The rollers have a running wheel rotatable in the use state about a horizontal axis, which is received in a support fork. For this purpose, the support fork usually has two fork legs which receive the axle ends and which are rooted in a clevis which forms an overlapping portion. At the overlapping portion or in the region of the fork head, a holding part is provided, by means of which the roller can be fastened to the method of operation. In the case of a castor, the support member is arranged so that in particular the support fork with the impeller is pivotable relative to the support member about a vertical axis in the use state. In the case of a castor, the support member is preferably rotatably connected to the support fork. With regard to the known state of the art, the object is to develop a role of the type in question or a roller attached to a carrier improved such that a handling-friendly mounting on the carrier of the procedural object can be achieved.

A possible solution of the problem is given according to a first inventive idea in a role in which it is geared to that the support member for sliding attachment by moving the roller in a plane which extends parallel to a mounting state to a horizontal plane in which extends the wheel axis , is trained.

With respect to the roller mounted on a support, it is considered that the support member and the counter-mounting member for sliding attachment by movement of the roller in a plane which is parallel to a mounting state parallel to a horizontal plane in which the wheel axis extends formed.

The role is according to the proposed solution in a technically favorable manner to the support of the procedural object fixable, this according to a molded sliding attachment. The roller-side holding part as well as preferably the counter-holding part fixed to the carrier, for example by gluing, welding or screwing, are designed such that the holding part captures the counter-holding part or vice versa in the course of a sliding movement of the one part relative to the other part. The sliding displacement is preferably carried out in a plane which runs parallel to a in the assembled state, further in particular in the operating state in which the roller attached to the support is supported on a floor, horizontally extending plane which receives the impeller axis. The push-on movement for fastening the holding part to the counter-holding part is preferably stop-limited. More preferably, the fixing position of the roller is secured to the carrier. The assembly of the roller to the carrier is preferably carried out without tools. With the repeal of a preferred backup also disassembly of the role of the carrier is also accessible in handling technology favorable manner. The support member forms in a preferred embodiment, a perpendicular to the direction of displacement and thus preferably in the mounting or use state vertically acting rear handle. This is achieved in particular by mounting part sections, which lie in a cross section through the support member and the counter-support member in the connecting state transversely to the direction of top and bottom in vertical overlap to a directly cooperating with the support member portion of the counter-support member. The inclusion of the counter-support member or a portion thereof in the support member is therefore preferably solely by switching on or off in or out of a correspondingly profiled in cross-section region of the support member possible.

Thus, the counter-holding part is preferably adapted in its contour to the given in the direction of displacement contour of the support member, so viewed in particular with respect to a width extension transverse to the direction of displacement.

Preferably, the rear grip contour of the counter-holding part is smaller than the rear grip contour of the holding part. With reference to a section in a vertical plane, a lower vertical height of the rear grip section to be inserted or pushed into the retaining part is preferably obtained in comparison to the rearward engagement section of the latter. gene holding part receiving free area of the support member, which free space is covered by at least one rear grip portion of the support member. The counter-holding part is in the assembled state with the interposition of a spring element in the support part. In a preferred embodiment, the spring element compensates for the difference between the rear grip portion of the counter-holding part and the receiving area of the holding part considered in the vertical direction in the use state. More preferably, the spring element in the assembled state acts on the counter-holding part in such a way that it is urged at least in the vertical direction upward against the rear grip sections of the holding part forming the rear grip.

The spring element is preferably in the course of a sliding displacement of the counter-support member with elastic deflection overflowable until a

Detent opening for the spring element is achieved. The latching opening is preferably formed in a facing region of the counter-holding part. As a result, a backup of the mounting position is given. This backup is at least cancel the dismantling of the role of the carrier by, for example, a displaced back into the locking opening in the counter-holding part spring tongue by means of a tool in a release position is shifted back.

A hard plastic is possible in this regard. The spring element is preferably adhesively bonded or latched to the holder part, furthermore connected in particular captively to the holder part, is correspondingly part of the roller to be fixed on the carrier. Furthermore, the invention relates to a roller, in particular castor or castor, with an impeller having an impeller wheel which is received in a support fork, wherein the support fork forms an overlap portion with respect to the impeller and on the overlapping portion on the upper side a fixing pin is provided.

The mounting pin, which can also be formed as a preferably integrally formed with the support member pin extends in mounting position, further in particular in the use position of the roller in the vertical direction, this further preferably in training the role as a steering roller cen- rally the steering axis receiving.

To solve the problem set in the introduction, it is pointed out that the mounting pin extending in a mounting direction in a vertical direction is designed as a tapering cone tapering towards its free end.

Further preferably, the mounting pin is rotationally symmetrical to a vertical axis of rotation in the mounting or use state pin or a steering axis when forming the roller as a castor truncated, facing the overreaching portion has a larger diameter than in the overreaching portion facing away, vertically upwards spaced end portion of the fastening pin.

It is provided a cone angle of preferably 0.5 to 2 °, in particular 0.75 to 1.5 °, which cone angle is in the range of self-locking with a corresponding configuration of the counter-support member. The cone extends preferably over a vertical length (vertical extension length of the vertically above the overlapping portion of the support fork freely projecting fastening pin) of 30 to 70 mm. More preferably, this free vertical length of the mounting pin corresponds to about 0.5 to 2 times, more preferably about 0.8 to 1.5 times the considered in the use position horizontal distance of the impeller axis receiving ends of the fork legs.

In one embodiment, the support part attached to the support is designed as a co-sleeve, for cooperation with a holding part of the roller designed as a conical pin, wherein the conical angles of the conical and conical shafts are adapted to each other, more preferably the same. Thus, the conical sleeve preferably has a cone angle of 0.5 to 2 °, more preferably 0.75 to 1.5 °. According plugging of the mounting pin from preferably vertically down into the downwardly open conical sleeve is in handling technically favorable manner a preferably tool-free plug-in mounting of the roller on the support achievable, the plug-in position is formed according to the preferred cone angle self-locking. An alternative approach provides that the support member having respect to the mounting state has horizontally extending latching formations, which are overflowable in the vertical direction.

The roller is preferably configured for attachment to a carrier, wherein the detent fixing is achieved in particular by a movement of the roller and its support member with respect to a mounting and / or use state in the vertical direction. Due to the horizontally extending latching formations acting in the vertical direction rear grip sections arise. For overflowing the latching formations, the sections of the holding part which are located upstream in the plug-on direction and / or the flank pointing in the plugging direction of a counter-latching projection of a counter-holding part are provided, for example, with an oblique section or a rounded section. The support member is preferably a metal part, for example aluminum part. Alternatively, in this regard, a hard plastic part may be provided.

The latching formations are formed in a preferred embodiment as horizontally extending, opposite and parallel grooves in the region of outer walls of the support member, this further preferably in a substantially plate-shaped configuration of the support member. The support member is also preferably associated directly with the overlapping portion of the support fork.

In an alternative embodiment, the support member forms two substantially parallel to each other extending, opposite and between a free space leaving support walls, each having at their free ends the latching formation. Accordingly, in such an embodiment, the latching formations are vertically spaced from the overlapping portion, in particular to a passage plane of the support member by the overlapping portion. Another approach is based on an embodiment in which the roller attached to the carrier has a counter-holding part, which is not directly and appropriately pre-mounted attached to the carrier, but rather is designed as a Loseteil for attaching the roller to the carrier.

The counter-holding part is preferably formed U-shaped (with respect to the mounting state in a vertical cross-section transverse to the longitudinal extent of the carrier), wherein the U-legs are formed for locking engagement in merging the support member and the counter-support member.

For this purpose, the mounting part has horizontally extending latching formations in the assembled state, which are detected in the assembled state by counter-latching protrusions of the counter-mounting part. In a preferred embodiment of the holder part-side latching formations as grooves, the counter-latching formations of the counter-holding part are preferably designed as ribs adapted in cross-section.

By the latching connection between the support member and counter-support member a determination of the role of the support in the vertical direction is achieved, this taking the carrier between the U-legs of the counter-support member and in the vertical direction between the U-web of the counter-support member and the support member the role.

Between the U-legs preferably extends to the free end of the U-legs open sleeve. This is preferably rooted in the U-web of the counter-support member. The sleeve serves to receive a pin formed on the holder part, whereby an additional positive connection is achieved. With attachment of the counter-support member is spent under capture of the carrier profile of the pin of the support member in the sleeve. The U-legs of the counter-holding part here overlap the carrier, wherein in a preferred embodiment of the horizontal horizontal distance of the U-legs in the assembled state corresponds to the width considered in the same direction of the carrier substantially. It is also preferred that the inner contour of the counter-holding part formed in a cross-section, formed by the U-legs and the U-bar, be adapted to the outer contour of the carrier, so that in the fixing position preferably a large-area, in particular full-surface contact of the counter -Halterungsteiles on the outer wall of the carrier is reached.

The pin of the support member and the sleeve of the counter-support member pass through the carrier in one embodiment, to which the carrier has a corresponding, vertically aligned in the mounted state bore. As a result, an additional determination of the role is achieved even in the longitudinal direction of the carrier.

In one embodiment, the pin and the sleeve each have a length which corresponds to or exceeds the vertical height of the carrier. Alternatively, the length of the pin and / or the sleeve may be chosen smaller than the vertical support height.

The in the assembled state the U-web of the counter-support member facing surface of the support member is adapted in a further preferred embodiment of the facing contour of the carrier, so that in this area preferably a full-surface contact of the support member is achieved on the support. Thus, furthermore, the carrier in the connection region with respect to a cross-section is preferably encompassed over the entire length of the carrier by the holding part and the counter-holding part, all over the entire surface. The U-legs of the counter-support member are deflected in the assembled state to achieve a resilient bias. Thus, the counter-holding part, in particular its U-legs, is preferably formed of an elastically resilient material. Thus, the counter-support member made of a hard plastic. Alternatively, for example, in one embodiment of the counter-support member as a metal part by constructive means, such as partial material taper in the U-leg, given the required elasticity. The U-legs of the counter-support member can not be aligned parallel to each other in the unloaded position, ie before attaching the counter-holding member to the carrier, viewed in cross-section. Thus, the U-legs can extend inwards and towards each other inclined, for example, including an angle of 1 to 2 ° to a vertical in the assembled state. According plugging the counter-mounting member on the carrier and engagement of the counter-latching projections in the latching formations of the support member results in a pivotal displacement of the U-legs tend to be outwardly, which is given in the locked position a bias radially inward to secure the detent position.

The in mounting position facing each other leg surfaces of the iron-shaped counter-support part carry snap before jumps, which engage in correspondingly positioned and formed recesses of the wearer. As a result, a backup of the fixing position is also achieved in the horizontal direction. The determination of the role in the carrier is preferably carried out without tools sliding the bow-shaped support member on the carrier and locking device by clipping the counter-support member.

Another proposed solution provides that the mounting part has a plurality of mounting pins vertically aligned in the mounting position and one or more acting in the vertical direction latching formations are provided.

This Rastaus- shaping cooperates with a locking part of the counter-holding part, which is U-shaped to engage over the carrier.

More preferably, a locking part is provided on each U-leg of the support member, for corresponding cooperation with a correspondingly formed in the support member Rastausformung. The counter-support member forms receptacles for the support pins of the support member. Preferably, these recordings are adjusted with respect to their vertical depth in the mounting position as well as in terms of their cross-section (diameter) to the dimensions of the support pin.

It is a plug / clip connection reached, which can be made in handling technology favorable manner without tools. The roller is clamped to the carrier, for which purpose the counter-holding part in the region of the U-opening and the corresponding section of the holding part are preferably contour-adapted to the outer contour of the carrier.

Also provides a further proposed solution that the support member Uf is formed örmig formed by the U-leg support walls, wherein on a support wall, a bracket is hinged, the latching connection with the opposite support wall under closure of a through the support walls in the assembled state to vertical upwardly directed opening is formed. The U-opening between the support walls of the support member is preferably adapted in cross section to the outer contour of the carrier to be embraced.

The pivot axis of the bracket extends in the mounting position transversely to a vertical axis, more preferably parallel to a longitudinal extension direction of the carrier, so that with a throwing over of the bracket this overhangs the top of the carrier.

In the region of the end of the stirrup opposite or facing away from the hinge, the stirrup is provided with a latching part for latching laying the bracket on the hinge side opposite U-leg of the support member. For this purpose, the U-leg on an overflowable Rastausformung. The role is clamped over the support member and the swiveled thereto bracket on the support, the determination is preferably without tools and thus handling technology low feasible.

A further proposed solution provides that in a mounting state in the vertical direction extending fastening pin or pin of the support member has a circumferentially extending holding profiling profiled.

In this case, the mounting profiling can be a circumferential or even only partially circumferential groove with respect to an axis that passes centrally through the fastening pin. It can be provided in this regard, a plurality of such grooves in the axial direction arranged one behind the other.

When a groove is formed, it is provided with an axial distance to the free end of the pin, which distance preferably corresponds to 0.25 to 1 times the pin diameter. The free end of the pin is mushroom-shaped.

As an alternative to an embodiment of the mounting profiling according to the shape of one or more grooves, it is also possible to provide a completely or partially circumferential collar or a plurality of such collars in an axial rearward arrangement.

The radial height of a Elevation or the radial depth of a depression relative to the uninfluenced lateral surface preferably corresponds to one hundredth to one fifth, in particular one fiftieth to one tenth of the journal diameter.

In a further preferred embodiment, the mounting profiling is formed in the region of a free end of the fastening pin facing away from the overlapping portion of the mounting fork. The mounting pin passes through in the mounting position, the carrier in the region of a correspondingly provided bore, more preferably the provided with the mounting profiling end of the mounting pin projects beyond the roller opposite side of the carrier freely for detection. This freely projecting end of the fastening pin is detected for fixing the roller to the carrier by the counter-holding part. This is substantially U-shaped and preferably has on opposite inner surfaces of the U-legs Halterungsausformungen which engage in the mounting profiling of the support member.

In a web-like support profiling of the support member, the Halterungsausformungen are formed in the form of grooves.

The holding state is secured by an elastic construction of the counter-holding part. Thus, the counter-holding part is elastically deformable, in particular transversely to a longitudinal extension of the carrier, which is represented by a corresponding chende choice of material of the counter-support member and / or can be achieved by design measures.

The positive connection between the counter-holding part and the holding part, more particularly between the counter-holding part and the holding profiling of the holding part having end of the fastening pin is achieved in one embodiment by pushing or bouncing of the counter-holding part in the direction of an axis passing through the fastening pin ( Vertical axis in the assembled state).

Alternatively, a pushing on of the counter-holding part with respect to the axis of the fastening pin from radially outward in the direction radially inward, further substantially in the direction of a longitudinal extent of the support reach, thereby capturing the profiled mounting spigot end, to which the counter-holding part a corresponding edge open Having insertion opening in the direction of the Halterungsausformungen.

As a result of the formation of a circumferential latching groove in the region of the free end of the fastening pin, a mushroom-shaped projection can be provided. The end-side mushroom head formed in this way is positively captured, in particular by pushing the counter-holding part in a direction transverse to the extension direction of the fastening pin, for vertical clamping of the fastening pin and, consequently, for holding the roll on the carrier. The preferred bracing is achieved, in particular, according to the elastic configuration of at least the areas preferably supported on the carrier, for example U-legs of the counter-holding part.

The counter-support member may also be a spring element, which is supported directly under elastic deformation on the support. For example, the spring element is an elastically resilient hard plastic part. In this regard, preference is given to a metal spring part, for example a leaf spring, which acts in the positive locking position with the actuating pin or with the mushroom head of the actuating pin resiliently in the vertical direction.

Alternatively, the counter-support member is supported on a system part, wherein the system part is in turn supported on the carrier. In this case, the plant part preferably has a form-fit formation adapted to the facing outer contour of the substrate, for adapted fitting of the plant part on the carrier. The surface of the contact part lying opposite the form-locking formation in the vertical axis direction is preferably planar, further in particular directed perpendicular to the vertical axis. On this flat surface, the spring element, in particular in the form of a leaf spring, is supported. The support member has a form-fitting formation, which bears against the outside of the carrier. Thus, a concave configuration, viewed in the direction of the free end of the fastening pin, of the surface of the holding part facing the carrier is preferably provided, which in a preferred embodiment is adapted to the cross-sectional configuration of the carrier section to be allocated.

Also, the counter-holding part preferably has a form-locking formation, which bears against the outside of the carrier. This form-fit formation is preferably rounded in the cross-section opposite to the form-fitting formation of the holding part.

The securing in the longitudinal extent of the carrier is achieved by the passage of the fastening pin through the carrier-side bore.

A further proposed solution is provided, in which the fixing pin extending in a mounting state in the vertical direction has a secant-like latching groove which opens in a view which reproduces the cross-sectional profile of the latching groove, including an acute angle directed towards the support fork. The latching groove extends in this case with respect to a vertical section through the mounting pin, starting from radially outward into the region of the central axis of the fastening pin, so that a radial dimension of the latching groove with respect to the axis is established, which radial dimension corresponds to 0.3 0.6 times the diameter of the fastening pin in a, the locking groove intersecting transverse plane corresponds to the axis.

According support of the counter-support member on the roller-side support member results in an action of the latching groove in the axis on the mounting pins, which acts by the obliquely rising latching groove a force component vertically upwards on the mounting pins. As a result, a tension of the fastening pin against the counter-gene holding part is achieved.

The counter-support member flanked in the mounting position, the carrier on both sides, which carry the carrier flanking portions of the counter-support member in the region of a vertically upper end of the axis and come in a contrast lying lower end to rest against the support member.

The determination of the role is carried out according to pivoting, for which purpose the counter-mounting part forms a U-shaped grip area, which offers a pivotal attack for mounting.

The axis of the counter-holding part is used for mounting in the slot-shaped locking groove of the actuating pin, which locking groove above and on the opposite side of the support member is freely accessible. By pivoting the handle area in the direction of the carrier and

Supporting portions of the counter-support member on the roller-side support member is achieved a tension, preferably a Festlegungsstellung is reached after exceeding a dead center in the course of Verschwenkvorganges. In this fixing position, the U-shaped grip region preferably lies over a large area, in particular over its entire surface, against the outer wall of the carrier.

The counter-holding part is preferably formed as a sheet-metal bent part. Also proposes a solution that in a mounting state in the vertical direction extending mounting pin has in the foot region extending transversely to the longitudinal extension of the mounting pin Achsausformungen.

The mounting bracket penetrates in the mounting position preferably the carrier according to reaching through the fastening pin by corresponding vertical holes in the carrier. It is further preferred a plate-shaped foot portion is provided, which facing the carrier has a form-fitting preferably in the form of a concave cavity. Starting from the plate-shaped foot region, the axle formations extend freely radially outward with respect to the vertical axis passing through the fastening pins.

Thus, the counter-support member is pivotable by rotating about the Achsausformungen between a release position and a support position, wherein in the support position of the U-region of the counter-support member preferably over a large area, in particular over the entire surface rests against the outer wall of the carrier.

The counter-holding part has one or more latching formations for cooperation with the carrier in the assembly position. The resting place ments are preferably formed in an elastically resilient region of the counter-holding part, for example in a spring region of the counter-holding part formed by a free cut. In a preferred embodiment, the latching recess is a latching projection pointing in the direction of the carrier, which in the assembled position dips into a correspondingly positioned opening in the carrier wall. Alternatively, the latching formation is formed by a resilient deflectable designed under-handle portion, which undercuts in the mounting position, the investment area of the counter-holding member on the support opposite underside of the carrier.
