- the present invention is described herein as being used to trim Venetian blinds V having a headrail H, a bottom rail R, and slats S in a single operation, one having ordinary skill in the art will appreciate that the present invention also can successfully be used to trim the individual elements or combinations of elements of the blinds (e.g., the bottom rail R, all of the slats S, individual slats S, and the headrail H). Additionally, one having ordinary skill in the art will appreciate that, while the invention is described herein as being operable to trim Venetian blinds, the invention can also successfully be used to trim other window coverings.
- a blind trimming apparatus 10, embodying the invention is illustrated in Figs. IA, IB, and 2. Portions of the apparatus 10 are similar to conventional blind trimming apparatus, such as those described in U.S. Patent Nos. 5,806,394,.6,178,857, and 6,196,099 and Published U.S. Patent Application No. 2001/0054338, which are incorporated herein by reference.
- the apparatus 10 includes a base plate 12 and a frame 14 fixed to and extending upwardly from the base plate 12.
- the frame 14 at least partially defines (Fig. 3A) a headrail opening 16 adapted to receive headrails H, a bottom rail opening 18 adapted to receive bottom rails R, and an elongated blind slat opening 20 adapted to receive slats S.
- a first axis A extends in a generally horizontal direction through the frame 14 and the blind slat opening 20.
- guides or rails 26 extend along a face of the frame
- first carriage or die plate 28 for sliding movement in a direction substantially parallel to the rails 26 along a first cutting path 30 between a first retracted position (shown in Fig. IA) and a first extended position (shown in Fig. IB).
- the rails 26 are spaced-apart and extend along generally parallel axes at an angle of about 45 degrees with respect to axis A. In this manner, at least a portion of the first cutting path
- first carriage 28 is at an angle of about 45 degrees with respect to the first axis A. It would be readily understood, however, that the rails 26 can be successfully arranged differently to facilitate movement of the first carriage 28 along an arcuate path, a horizontal path, a vertical path, or otherwise to define the desired cutting path.
- the first carriage 28 defines a headrail recess 32, a bottom rail recess 34, and a central cutout 36.
- the headrail recess 32 and the bottom rail recess 34 are arranged to correspond with the locations of the headrail opening 16 and the bottom rail opening 18, respectively.
- a portion of a headrail H is inserted through the headrail opening 16 and into the headrail recess 32 and a bottom rail R is inserted through the bottom rail opening 18 and into the bottom rail recess 34.
- the first carriage 28 is then moved along the first cutting path 30 (i.e., in a generally downward path) laterally with respect to the frame 14 to shear the headrail H and the bottom rail R between the first carriage 28 and the frame 14.
- the blind trimming apparatus 10 also includes a drive assembly 40 that is operable to move the first carriage 28 along the first cutting path 30.
- the drive assembly 40 includes a handle or lever 42 which is fixed to an eccentric cam 44 and which is operable to pivot the eccentric cam 44 into engagement with an aperture 46 in the first carriage 28.
- the eccentric cam 44 pivots into engagement with a lower edge of the aperture 46, causing the first carriage 28 to move downwardly along the first cutting path 30 toward the first extended position.
- the headrail H is sheared between the headrail opening 16 in the frame 14 and the headrail recess 32 in the first carriage 28 and the bottom rail R is sheared between the bottom rail opening 18 in the frame 14 and the bottom rail recess 34 in the first carriage 28.
- the handle 42 can be returned from the second position to the first position to thereby also return the first carriage 28 to the retracted position.
- the blind trimming apparatus 10 also includes a blade arrangement 48 having a second carriage 56. As shown in Figs. 2, 3A, 3B, and 4, the second carriage 56 is a . substantially U-shaped member having forwardly extending spaced-apart legs 58a, 58b and defining an internal space 63 between the legs 58a, 58b. Forward ends of the legs 58a, 58b define blade recesses 62a, 62b (shown in Figs. 2 and 4).
- Guides or rails 50 extend into the frame 14 and extend laterally along a surface of the frame 14 in a direction substantially parallel to the first axis A.
- the second carriage 56 is slideably mounted on the rails 50 for movement along a second cutting path (represented by arrow 57 in Figs. 3A and 3B) extending between a second retracted position of the carriage 56 (shown in Figs. IA and 3A) and a second extended position of the carriage 56 (shown in Figs. IB and 3B).
- the blind trimming apparatus 10 includes a second drive assembly 54 (shown in Figs. IA and IB) that is operable to move the second carriage 56 between the second retracted position and the second extended position.
- the drive assembly 54 includes two spaced-apart cylindrical rails 51 supported on the base plate 12.
- the second carriage 56 is coupled to a follower 52 with two parallel through-holes 60.
- the rails 51 extend through the through-holes 60 in the follower 52 to guide movement of the second carriage 56 between the second retracted position and the second extended position.
- the second drive assembly 54 also includes a connecting rod 76 (shown in Fig. IA) operably connected to the first drive assembly 40 so that pivoting movement of the handle 42 also causes movement of the second carriage 56 between the second retracted position and the second extended position, hi this manner, an operator can simultaneously move both the first and second carriages 28, 56 between their respective retracted and extended positions with a movement of a single handle 42.
- the first and second drive assemblies 40, 54 can be uncoupled and made to be independently operable so that the first and second carriages 28, 56 can be moved independently.
- the blade arrangement 48 also includes a cutting blade 64, which is coupled to the forward ends of the legs 58a, 58b and extends across the internal space 63.
- the cutting blade 64 includes laterally extending flanges 66a, 66b and an arcuately shaped cutting edge 68 extending between the flanges 66a, 66b. As shown in Figs. 3A, 3B, and 5, the flanges 66a, 66b are configured to be received in and closely engage the blade recesses 62a, 62b of the second carriage 56.
- Forward portions 69a, 69b of the flanges 66a, 66b extend outwardly from the leading edge of the cutting blade 64 a short distance (e.g., between about 0.10 inches and about 0.23 inches in the illustrated construction) beyond the cutting edge 68.
- the flanges 66a, 66b define locating recesses 70a, 70b.
- the locating recesses 70a, 70b are generally C-shaped notches located on interior sides (i.e., opening toward the interior space 63) and extend laterally through the flanges 66a, 66b in a direction substantially parallel to the first axis A.
- the recesses 70a, 70b can be located in other positions on one or both of the legs 58a, 58b of the second carriage 56 and/or on the cutting blade 64.
- forward ends of the locating recesses 70a, 70b open through the forward portions 69a, 69b of the flanges 66a, 66b. In this manner, the forward ends of the locating recesses 70a, 70b are spaced a short distance from the cutting edge 68 along the first axis A.
- the cutting edge 68 can become nicked, dulled, and/or misshapen.
- the blade arrangement 48. also includes fasteners (not shown) which selectively and removeably fix the flanges 66a, 66b to the legs 58a, 58b. In this manner, when the cutting edge 68 is damaged, an operator can remove the cutting blade 64 for sharpening, or alternatively, an operator can replace the damaged cutting blade 64.
- the cutting tool 78 includes a support flange 79 which extends outwardly from a rearward end of the cutting tool 78 and is configured to be received in a slotted recess (not shown) in the frame 14.
- the support flange 79 travels with the cutting tool 78 along the slotted recess in the frame 14 to accommodate movement of the cutting tool 78 during trimming operations. Additionally, the engagement between the support flange 79 and the slotted recess limits movement of the cutting tool 78 relative to the frame 14 within a desired travel area or path and prevents the cutting tool 78 from inadvertently becoming separated from the frame 14. As shown in Figs.
- the blade arrangement 48 also includes a die or cutting tool 78, which extends outwardly from the frame 14 into the blind slat pppning 20 and defines a second axis B that intersects the first axis A at an angle of approximately 90 degrees.
- the cutting tool 78 is moveably coupled to the frame 14 for movement along the second axis B.
- the cutting tool 78 is moveably coupled to the frame 14 for movement along a third axis C, which is substantially perpendicular to the first and second axes A, B.
- the cutting tool 78 has a generally arcuately shaped cutting edge 80 that is shaped to correspond to the generally arcuately shaped cutting edge 68 of the cutting blade 64. More particularly, as described in detail below, the cutting edge 80 is arranged and shaped to closely engage the cutting edge 68 of the cutting blade 64 to shear portions of the blind slats S located in the blind slat opening 20. In other aspects and in other constructions (not shown), one or both of the cutting edges 68, 80 can have any other shape to provide different blind slat configurations (e.g., dog-eared, pointed, and the like) but are preferably similarly shaped to facilitate a shearing interaction during trimming operations.
- different blind slat configurations e.g., dog-eared, pointed, and the like
- Flanges 82a, 82b extend outwardly from the cutting tool 78 on opposite sides of the cutting edge 80 and include respective engagement surfaces 84a, 84b. Additionally as shown in Fig. 6, the cutting tool 78 includes two substantially pointed locating projections 86a, 86b. In other aspects and in other constructions (not shown), the cutting tool 78 can include one, three, or more locating projections 86a, 86b. Additionally, in other aspects and in other constructions (not shown), the locating projections 86a, 86b, can have other shapes and configurations (e.g., arcuate, dog-eared, T-shaped, and the like). As explained in greater detail below, the locating projections 86a, 86b are configured to matingly engage the locating recesses 70a, 70b on the cutting blade 64 to facilitate indexing or alignment of the cutting tool 78 with respect to the cutting blade 64.
- an operator moves the first and second carriages 28, 56 to the first and second retracted positions (as shown in Fig. IA and as partially shown in Fig. 3A).
- the operator then inserts a portion of the headrail H through the headrail opening 16 and into the headrail recess 32, a portion of the bottom rail R through the bottom rail opening 18 and into the bottom rail recess 34, and the blind slats S into the blind slat opening 20 and the central cutout 36.
- the operator then operates the first and second drive assemblies 40, 54 to move the first and second carriages 28, 56.
- the operator pivots the handle 42 (e.g., in a clockwise direction as represented by arrow 43 in Figs. IA and IB), moving the first and second carriages 28, 56 along the first and second cutting paths 30, 57, respectively.
- the first carriage 28 moves along the first cutting path 30 and cooperates with the frame 14 to shear one or both of the headrail H and the bottom rail R.
- the cutting edge 68 of the cutting blade 64 engages individual slats S located i ⁇ the blind slat opening 20.
- Lateral motion of the cutting blade 64 causes the cutting edge 68 to cut through or trim the individual slats S.
- the cutting blade 64 approaches the cutting tool 78.
- the forward ends of the locating recesses 70a, 70b move into engagement with the locating projections 86a, 86b of the cutting tool 78.
- the engagement between the locating projections 86a, 86b and the locating recesses 70a, 70b causes the cutting tool 78 to move along the second axis B into engagement with the cutting blade 64.
- the engagement between the locating recesses 70a, 70b and the locating projections 86a, 86b causes the cutting tool 78 to move along the third axis C into engagement with the cutting blade 64. More particularly, the engagement between the locating recesses 70a ? 70b and the locating projections 86a, 86b indexes or aligns the cutting blade 64 and the cutting tool 78 so that as the cutting edge 68 of the cutting blade 64 passes across the cutting edge 80 of the cutting tool 78, the cutting edges 68, 80 are spaced-apart by a predetermined distance (e.g., between about 0.000 inches and about 0.001 inches).
- a predetermined distance e.g., between about 0.000 inches and about 0.001 inches
- Movement of the cutting tool 78 along the second axis B is limited by the interaction between the engagement surfaces 84a, 84b and the flanges 66a, 66b so that the cutting edge 80 of the cutting tool 78 is preferably prevented from moving into locking engagement with the cutting blade 64.
- FIG. 7-9 A second construction of a blade arrangement 48B for the blind trimming apparatus 10 is illustrated in Figs. 7-9. Common elements are identified by the same reference number "B".
- a carriage 56B is moveable along a cutting path (represented by arrow 57B in Fig. 7) which is substantially parallel to the first axis A.
- the carriage 56B supports a cutting blade 64B, having flanges 66aB, 66bB and a cutting edge 68B extending between the flanges 66aB, 66bB.
- forwardly extending legs 58aB, 58bB of the carriage 56B define blade recesses 62B (only one is shown in Fig. 7) and the flanges 66aB, 66bB are positioned in the blade recesses 62B.
- Fasteners removeably couple the flanges 66aB, 66bB to the carriage 56B and facilitate blade removal and blade replacement. Interior sides of the flanges 66aB, 66bB provide locating projections 7OaB, 7ObB.
- the locating projections 7OaB, 7ObB are rectangularly shaped and extend laterally along the length of the flanges 66aB, 66bB.
- the locating projections 7OaB, 7ObB can have other shapes and configurations (e.g, dog-eared, T- shaped, pointed, arcuate, and the like).
- the frame 14 supports a cutting tool 78B having a cutting edge 8OB and defining locating recesses 86aB, 86bB located on opposite sides of the cutting edge 80B.
- the locating recesses 86aB, 86bB are , substantially rectangular and are configured to matingly engage the locating projections 7OaB, 7ObB of the cutting blade 64B.
