BACKGROUND OF THE INVENTION Retail stores often sell different types of window coverings, such as upholstery, draperies, venetian blinds, and louvers. These window coverings generally extend horizontally through the entrance to 3a. window and are typically dime-psionadaí-- to accommodate the window entrance t mafto »A popular type of window cover is the window lattice with bez rail, bottom rail and cover material between the rail head and the bottom rail. Common window cover material includes splints, such as PVC boards or boards. A problem with such window lattices is that the width of the rail df »c ^ bcz-? L, the background one?

In response to this problem, there has been a diversity of applications, so that users can obtain them from adapted windows, which can be adjusted. - According to the first option, the customer typically visits a specialized store, shops for apartments and makes an order for usual window lattices, this option requires the customer to measure First enter the window and present the measurements to the seller ..

Then, the seller will take the order to the factory or distribution center, where the window lattice cut to the specified length * This option is mostly time consuming because the client must at least make visits to the store in order to obtain the desired product, eg, in the first visit make the order and in the second pick up the product. In addition, this particular option is relatively expensive. The second option includes selecting the window lattice from the existence of cel- e? - pre-prepared, stored in the retail establishment. Typically, if the sizes have certain sizes because some v. Tons entries, especially in newer homes and offices, are of dimensions, standards. These celasias of window in preal acenaje and standardized s n ur-m im nt much less expensive »aue i« «-.

The frame is preferably mounted on the base to form a rigid structure. The frame and the top surface define the receiving area between them that receives one or more window lattices, the cells must be cut by the apparatus. The set dc-3 cut is installed sliding to the frame, sliding along the axis of movement towards and outside the receiving area. (~ 1 mark preferably includes one or more guiding tracks, which make an angle with respect to the mole surface of the base and the assembly is cut into the race tracks, so that the center line Movement is diagonal to the top surface of the base.The cutting assembly includes the cutting blade with a cutting edge between the receiving.The cutting apparatus also includes a mechanical element, such as a drive, which can be put into operation by imparting the sliding movement to the cutting unit, the up-rip impeller includes a carrier and an arrangement of the shunt, the catch mechanism, the activated element of osca or, © lementw pneumatic or electric motor driven device In a particular scorched fip-ntaci.on, the cutting joint includes an e so that "has a diversity of tooth." The pipion, having a diversity of teeth in the periphery of it, is installed rotationally in the mark »The pipion will couple it in engagement with the carrier, so that when the piphon is rotated, the pinion imparts sliding movement to the cutting assembly, moving the diagonal cutting blade through the receiving area, cutting the lattice window in the specified length The base can include a support guide, provided on the top surface thereof, guiding the movement of the window lattice through the top surface of the base and towards the receiving area. In the selected representations, the support guide includes a mandrel that at least engages one of the headrails to the base rail and which more preferably engages the head rail} during cutting operations. The mandrel extends along the top surface of the base from a first end of the tape surface to the second end of the tape surface. The second end of the abutment surface is preferably adjacent to the cutting blade In some selected representations the base includes a joint of clamps which ensures the window lattice on the abutting surface of the base. prp »ff - rent6.m < ar.t »incJuye a loq is of abra?« d "ra with a threaded diameter.

The rotation of the crank moves the block of abr was in and out of the hook with Ja c-e-lae-i window. Preferably, the rat crank clockwise or counterclockwise, so that it applies a staple ring to the window lattice. In other chosen representations, the clamp may include a pneumatic device, an electrically operated device, a turning device, a retainer device or a weight. The cutting blade is preferably provided in the secondary end of? the top surface, having a longitudinal axis, which is substantially perpendicular to the longitudinal axis of the guide rail. The cutting blade T has a first face that is substantially flat and a second face that includes a damped portion. The bagged portion of the cutting blade is preferably the only section of the blade that engages and cuts the window lattice. The pocket goes up ancicamente is thinner than the raa of the cutting blade that surrounds the pocket. The bagged portion includes a tapered region, which is contiguous with the cutting blade and extends up and apart from the cutting edge. The tapered region has a first tapered or bevelled section, which extends from the barri-ds cor1! -. The first tapered section and the first sub-section of the first instrument define the first acute angle. The tapered region includes a second tapered region, which extends from the first tapered section.

Removing the stop surface The cutting blade preferably includes any material that occurs naturally or artificially, having the edge and / or durability to efficiently cut through the lattice joint and more preferably includes carbide or diamond oil The cutting apparatus also preferably includes a measurement set, adjacent and / or downstream of the cutting blade for measuring window celasia. Specifically, the measurement set provides a measuring tool to define the exact length of the final portion of the window lattice to be cut. The measurement assembly preferably includes a stop block, which butts against the final portion of the window lattice. The stop block is connected to the "cylinder" of the cam, at which it "sees", corre- sponds to the pinion, so that the stop block moves away from the window lattice end. , as the cutting blade is cut through the window lattice. For camp j, apart, c > The stop block allows the final cutting portion to fuse the lattice of »von ü- a gi e apart from the» cutting blade, which minimizes them. forces exerted by the cutting blade on the window lattice. Thus, the stop block is movable between the first position and the second position. In the first position, the stop block splices against the final portion of the lattice window. In the second position "the stop block is not. in contact with the final portion of the window lattice since the cams of the stop block separate from the end portion Another aspect of the present invention provides a method of cutting window lattice to a specific length. In some selected representations, the window lattice cutting method includes providing a cutting apparatus with a receptara to receive the window lattice, whereby the cutting apparatus includes a sliding window lattice mounted thereon to be detached from the lattice. the axis of the movement axis, towards and outside the k &at the receiver. Next, the window lattice in the receiving area and the window lattice p & cutting a final portion of window lattice by providing a window lattice of a specific length. Initially, the window lattice is inserted inside the first rail of the cutting apparatus and extends from the top surface of the base towards the blade. of cutting, so that the short blade is superimposed on the final portion of the window lattice., which must be cut off. In on es, the measurement set is used to determine the exact length of the final portion of the window lattice that is. being cut. Once the 1st edge of the end portion has been stopped, the handle of the shoulder joint rotates, so that the clamp block moves within the latch with the window lattice to secure the 3a. window lattice between the clamp block and the guide rail. The crank continues to rotate until the clamp block has secured the window lattice above the top surface of the base. Then, the piphon is rotated by moving the cutting assembly. Preferably »the crank is connected to the piffon to facilitate the rotation of the piPhon. The rotation of the piphoon runs the set of cartels in angled guide tracks along the axis of movements which is diagonal to the surface tape of the base, so that the window lattice slides diagonally through the window lattice. . As the card blade slides through the window lattice, the cams of the stop block are separated from the end portion of the window lattice being cut, so that the cut end portion is free to rotate separated from the cutting blade. As the end of the window lattice puq «sfis í» ßi.i «ndr-- car" -: -.It remains -free to adjust "cmrt- <l of the blade, the compressive forces exerted The blade on the window frame is greatly reduced, which greatly reduces the likelihood that the head rail or the fan rail will break while the cut is made, after the window lattice has been completely cut, the direction of the crank is preferably reversed to return to the window lattice to its initial position, the measurement set moving back to the knife blade as the crank is returned to its initial starting position. This point, the window lattice can be removed from the cutting apparatus, In certain opportunities, it may be preferable to cut or cut a second end of the window lattice to a specific length.This can be accomplished by inserting the second extreme of the celasia of window within the cutting apparatus, repeating the raisins described above.

The poster apparatus 20, which is preferably provided with a support device, such as a table. The cutting apparatus 20 will preferably be screwed or firmly secured to the table. The. table can have adjacent and / or falling from the blade opening carte 32 so that the end portion of the lattice cut window 36 can fall through the opening and into a trash bin. Typically, the customer interested in the window lattice cut to length specifies the length. Seller (hereinafter referred to bed the "operator") the dimensions of one to several window openings.The operator can then refer to a letter, typically supplied by the manufacturer uncle the window lattices, in order to select a jealousy Preferably, the manufacturer will supply 5 to 10 and even more different lattice models.The manufacturer's letter may also provide the operator with information concerning how many inches in feet should be cut in one to both OH remes of the window lattice 'With reference to Figures 6A and 6B, e end 128 of the window lattice. 36 to be cut is preferably passivated at the first end 52 of the abutment surface 24 of the base 22. Desput ts that the end caps 44 (not shown) have been removed from the rail of c-abeic-al 38 and tf.1 base rail 40, the refosla dfc v &ampFig. 36 is preferably aligned above the abutment surface 24 so that the rail-zal 30 rail faces the guide rail or mandrel and ol. batting rail 40 in front of clamp block 60. The C-shaped abutment 42 at the top of head rail 38 is aligned and sliding on mandrel 58, where the head rail is considered to be captured by the mandrel » Once the head rail 38 has been captured by the mandrel 58, the window lattice 36 is moved or inserted towards the second end 3 of the stopper 24 and the stop block 118. The window lattice 36 is still inserted inside the poster apparatus 20 until the end portion 128 of the window lattice 36 splices against the stop block Í18. In this step, the card blade 32 is superimposed on the ai-trem portion 128 of the window lattice 36. After the window lattice 36 has been fully inserted into the cutting apparatus 20 and spliced against the block. at stop 118, the operator firmly secures the window 36 celasia in place above the tape surface 24, using the collar assembly. The operator rotates the crank 74, preferably in the clockwise direction, which rotates the shaft, which in turn causes the clamp block 60 to move towards the window 36 and T? mandrel 58. The or-er? rinr will continue * hand-tightening the crank 74 to which "-.1 clamp block > 0 splice against the base rail 40 and compress the window celasia 36 between the jaw block 60 and the mandrel ». As the window 6 has been secured above the abutment surface 24 of the base 22, the operator can cut the end 128 of the window lattice 36 Referring to FIGS. 2A and 2B, before the crank 86 can be pushed to cut the window lattice 36, the safety pin 88 must be retracted so as to release the rotation pin 82. As the safety pin 88 is held in retracted pasture, the crank 86 preferably rotates e > n descent towards the operator, which rotates a) pinion 82. As the pin 82 rotates, the teeth 84 of the pin 82 engage with the teeth 80 of the carrier 78, moving the set of board 30 downwards within the tracks of guide 28A and 28R in angle. As the card assembly 30 moves downward, the cutting blade 32 s © moves along the. movement axis designated A-A diagonally to the abutment surface 24 of the base 22 and the knife blade 3¡. In other words, the cutting blade ee moves in a direction that has the vertical component (axis of the y) and the horizontal component (axis of the x) «Bed the cutting blade 32a. it moves diagonally with respect to the surface area 24 of the base 22 and the window lattice 36 secured thereto, the card blade 32 is disengaged through the window lattice 36 in a diagonal direction.

J2 on 3 the window lattice 36, resulting in the formation of a cleaner cut. The debonding action also prevents the edges of the boundary and the bottom edges 38, 40 s & break or split With reference to Figure 6B, the window celasia is preferably configured on the abutment surface 24 of the base 22, so that the tab edge 90 is connected simul- taneously to the rail 40, the rail h- cat-ßaal 30 and ol Arterial of cover B window 41. Conforme! the cutting edge is routed through the lattice of the window 36 in a diagonal direction, the mandrel (58) supports the head rail 38, operating as an internal cuff, or the mandrel extends along the entire path to the second. end 54 of the surface area 24 of the base 22 and ends unimpeded before the first face 92 of the cutting blade 32, an extremely clean cut can be formed at the end of the head rail 38. The mandrel 58 also it prevents the head rail 38 from rotating while it is being cut, therefore it contributes additionally to the formation of a clean and straight bill. FIGS. 7A-7C show the cutter blade 32 above how the blade is cut. slides through the window lattice 36. The lattice window 36 and the base 22 san are represented as blocks for illustration clarity.

On the other hand, the cutting edge 9p is simultaneously attached to the base rail, the material of the cutting edge 90 is attached to the tape, complete with the window frame 36. In other words, the cutting edge 9p engages simultaneously with the base rail. window cover and rial. do head. Co or 4 shown in 1A Figure 715, the letter bar moves vertically to, along the axis and laterally to the axis of the x axis, ie, diagonally across E3 the window span 3 ¿. B? edge of carte 90 continues moving .- ».-! iagonly through the latticework of at ana 36 until the blade 32 has completely detached through the lattice 36, as shown in Figure 7C. During the complete operation, only the pocket 96 engages the lattice 36, which additionally minimizes the forces that the blade exerts on the lattice 36. FIGS. 8A and 813 show the side views of FIGS. 7A and 7C, respectively. When the blade 32 initially engages the window lattice 36, the stop block 1.18 splices against the end of the window lattice 36. Siq seizes, immediately after the blade 32 is slid through the window celasia 36. , the cams of the stop block 118 ST are of the window lattice 36, which facilitates the end portion 128 of window lattice 36, which is taught to be freely supported so that it freely rotates out of the blade As the end portion of the board 128 is not sufficient to rotate out of the blade 32, the forces ejected on the window blind 36 by the cuchi Lia of cor 32 are greatly reduced. This is of particular importance towards the end of the knife stroke or knife. ".2 .--- to ---! Cuts through completely from the window frame 36., because at this point there is a likelihood that the blade 36 will compress the head rail 38. bottom rail 40, which greatly increases the likelihood that these elements break. As shown in Figures 8A and 88, due to the first face 9 of the cutting blade 32 is vertical and / or I ssubstanci línente flat, the blade 36 provides the window lattice 36 with a clean, square cut As mentioned before, the pocketed portion 96 of the blade 32, which is much thinner than the remainder of the blade 36, is the only portion of the blade which hooks the window lattice, this minimal structure is chosen by the thickness of the short blade 32 actually cutting through the window lattice 36, thus preventing the head rail 38 and the rail, from the bottom 40 they break, fracture or remain in pieces when the window celasia is marked 36.

Bed bagged portion 96 is tapered, end portion 128 of the window lattice that is cut rotates out of the blade 32. When the blade reaches the bottom portion of the cut, the thickness of the blade 32 in that section is particularly thin, so removed the blade 32 does not break or break the blade. head rail 38 and the bottom rail 40. The pocket design results in only a thin portion of the blade 30 which contacts the window lattice 3 s and seizes the "solid" portion of the blade 32 surrounding the pocket? the embalmed portion 6 is abilized and prevents the blade 32 from being given during the cutting operation f After the end portion 128 of window lattice 36 has been completely cut off, the portion © Ntremo 128 lowers and separates from the apparatus of FIG. cutting 20, preferably through the opening in the support table. The crank 86 can then be rotated upward to its initial position, from which the cutting blade 32 will be moved out of the support 76-. As the crank 86 rotates upwards, the safety pin 88 re-engages the pinion 82 closing the pinion 82 in place and preventing further rotation of the pinion. Then the crank 74 is preferably rotated in the opposite direction to the r < * Lo, j releasing the brace out of a and on J? The window lattice 36 can be removed from the poster apparatus 20. The window lattice 36 can then be removed by removing the window lattice 36 from the first surface 52 of the surface. stop 24 of the base 22, so that the opening,In the form of C 42, in the head rail 38 can be released from the mandrel 58. If necessary, the second end of the window lattice 36 can also be cut to a specific length using substantially the same techniques as above. described.
