Definitions

  • This invention relates to a method and apparatus useful in the manufacture of an architectural covering, especially a covering for an architectural opening, such as a window blind or shade.
  • the invention particularly relates to a method and apparatus for routing or threading and then finishing the lift cords of window blinds and shades.
  • Lift cords in a blind or shade need to be of a particular length, corresponding to the width and vertical drop of the blind or shade, so that the blind or shade can be fully lowered.
  • US patent 2 703 447 discloses an apparatus for measuring and cutting the proper length of cord for a venetian blind. The correct length is obtained by adjusting the apparatus in accordance with the width and drop dimensions of the blind.
  • this invention provides a method comprising the steps of:
  • a second end of each length of cord is unwound from a continuous length of cord while threading and routing the first end of the length of cord, and the second end of the length of cord is advantageously cut from the continuous length of cord and then restrained at a predetermined distance from the head rail after threading and routing the first end of the length of cord.
  • This invention also provides an apparatus for routing and finishing lift cords of an architectural covering, comprising:
  • Figure 1 shows an apparatus, generally 1, of this invention.
  • the apparatus comprises a frame 2, on which are provided an elongate longitudinally-extending horizontal support member 3 and an elongate longitudinally-extending rail member 5 on the front of the support member 3.
  • first cord-finishing station 7 Mounted on top of the support member 3 is a first cord-finishing station 7 which can slidably move along the longitudinal length of the support member 3.
  • an upstanding abutment surface 9 At the right end of the support member 3 is an upstanding abutment surface 9.
  • the rear and front of the abutment surface 9 and the rear and front of the adjacent longitudinal end of the first cord-finishing station 7 are each provided with confronting longitudinally-extending tongues 11 and 13, 15 and 17, respectively, which can engage and position the longitudinal ends of a head rail C and a bottom rail D of a partially finished shade or shade precursor, generally A.
  • the partially finished shade A is a semi-finished pleated shade which has its pleated shade element B juxtaposed between its head rail C and bottom rail D.
  • a shade is described, for example, in US patent 5 058 650.
  • the partially finished shade A is shown just above the support member 3 of the apparatus 1, prior to the shade's being positioned on the support member 3 in the accommodation space (generally indicated by arrow 19) with its head rail C, blind or shade element B and bottom rail D in parallel juxtaposed relationship between the first cord-finishing station 7 and the abutment surface 9 on the support member 3 and preferably with its bottom rail D in front of its head rail C.
  • the first cord-finishing station 7 is slid towards the partially finished shade A, so that the tongues 11, 13, 15 and 17 engage the rear and front of the adjacent longitudinal ends of the head rail C and bottom rail D.
  • the partially finished shade A may already have been provided with openings E-E5 and F-F2 for the routing of lift cords (not shown), or such lift cord openings E-E5 and F-F2 may be formed after the partially finished shade A has been positioned on the apparatus 1.
  • the head rail C and bottom rail D of the partially finished shade A can be supported on the support member 3 of the apparatus 1 at a distance from one another much smaller than the intended full drop of the resulting shade. Preferably, however, this distance is slightly in excess of the stack size of the resulting shade.
  • Figure 1 also shows that a longitudinally-extending, frontally-facing measuring scale 21 is provided at the rear of the rail member 5.
  • Figure 1 further shows that, mounted on top of the rail member 5, in front of the measuring scale 21, is a second cord-finishing station 23 which can slidably move along the longitudinal length of the rail member 5.
  • the second cord-finishing station 23 can slidably move in front of the support member 3, in parallel to the first cord-finishing station 7, alongside the accommodation space (below arrow 19).
  • the second cord-finishing station 23 is provided with a pointer 25 which can be lined up with a particular index on the measuring scale 21.
  • the measuring scale 21 is preferably calibrated to correspond to the drop height of the partially finished shade A, under construction, so as to avoid the need to refer to reference tables or make calculations concerning lift cord lengths.
  • the first and the second cord-finishing stations 7 and 23 are each provided with means for cutting lift cords, such as the first and second cord-cutters 27 and 29, respectively, shown in Figure 1.
  • the cord-cutters 27 and 29 can be conventional lift cord cutters such as are described in US patent 2 726 448.
  • Each of the first and second cord-finishing stations 7 and 23 are also provided, adjacent to the means for cutting lift cords, with means for temporarily restraining lift cords, such as the first and second cord clamps 31 and 33, respectively, shown in Figure 1.
  • the first and second cord-finishing stations 7 and 23 are also each provided, adjacent to the means for cutting lift cords 27 and 29, with means for affixing lift cords together, such as the first and second crimping tools 35 and 37, respectively, shown in Figure 1.
  • Such crimping tools can be manually operated by a lever as shown in Figure 1 or by other mechanical, pneumatic, electrical or hydraulic means.
  • lift cords are affixed to one another by crimping a small metal tubular element (not shown) around them.
  • each of the first and second cord-finishing stations 7 and 23 is further provided with means to lock the station in an adjusted position, such as the first and second clamp screws 39 and 41, respectively.
  • the first cord-finishing station 7 is also preferably provided with a supply of a continuous length of cord, such as a spool 43 of cord.
  • the second cord-finishing station 23 is provided with means 45 for temporarily holding and positioning a cord-guiding structure, such as a cord lock (not shown), in which all the lift cords are to be received and which is thereafter attached to the head rail C of the finished shade A.
  • a cord-guiding structure such as a cord lock (not shown)
  • Such temporary holding and positioning means 45 can be in the form of a U-shaped bracket for holding and positioning the cord-guiding structure of the shade A before the cord-guiding structure is attached to an end of the head rail C.
  • Figure 1 shows that the support member 3, close to the abutment surface 9, is also provided with cord guides 47 and 49.
  • Figure 2 shows that a first length G of lift cord is unwound from the spool of cord 43.
  • the forward end of the first length G of lift cord is then threaded from the left end of the bottom rail D of the partially finished shade A through its routing path through a first opening E in the bottom rail D and from there towards and through a first opening E1 in the head rail C of the partially finished shade A.
  • the first length G of lift cord extends through several first openings F (shown in Figure 1) in the pleated shade element B of the partially finished shade A, through which openings F the first length of lift cord G has been threaded.
  • the first length of lift cord G is then guided in its routing path around the cord guides 47 and 49, towards the second cord-finishing station 23.
  • the forward end of the first length G of lift cord is then guided through the bracket 45 and the cord-guiding structure therein and is temporarily held by the cord clamp 33 of the second cord-finishing station 23, and the rearward end of this first length G of lift cord is cut with the first cord-cutter 27 from the spool 43 and clamped by the cord clamp 31 on the first cord-finishing station 7.
  • Figure 3 shows that two additional lengths G1 and G2 of lift cords are then routed through their respective cord paths in the same way described above.
  • the additional lengths G1 and G2 of lift cords are unwound from the spool of cord 43.
  • the forward end of the middle length G1 of cord is routed through its routing path through the second openings E2 and E3 in the bottom rail and head rail D and C and through the second openings F1 in the pleated blind member B, between the second openings E2 and E3, and the forward end of the right length G2 of cord is routed through its routing path through the third openings E4 and E5 in the bottom rail and head rail D and C and through the third openings F2 in the pleated blind element B, between the third openings E4 and E5.
  • the forward ends of the additional lengths G1 and G2 of lift cord are then each guided in their routing paths around the cord guides 47 and 49, towards the second cord-finishing station 23.
  • a conventional lacing needle 51 (shown in Figure 3) can be used.
  • Such a lacing needle is described, for example, in US patent US 2 698 116.
  • the cord ends extending from one end of the bottom rail D will usually be attached to an end cap structure (not shown) which can thereafter be attached to the bottom rail once it has been removed from between the first cord-finishing station 7 and the abutment surface 9.
  • the cord-guiding structure (not shown) can be taken from bracket 45 and be inserted, with all the lengths G, G1 and G2 of lift cords, in the opposite end of the head rail C once the head rail is removed from the apparatus 1.
  • the cord ends extending from the cord-guiding structure can additionally be finished by attaching them to a cord connector, ending in a common draw cord and tassel depending therefrom. In this way, a shade can be obtained, such as is described in US patent 5 058 650.
