Definitions

  • the invention is related to a retractable shade, comprising a first border or the like, at least one web of pleatable material, as fabric, fixed thereto, a second border at a distance to said first border, and at least two cord means extending inbetween said first and second border, wherein the web is provided on predetermined places with a profile element having one or more guiding means and clasping means for receiving a strip of the material-web in a clasping or pinching way and wherein each of said cords being guided through said guiding means.
  • this shade is provided at certain places with a profile such that in the fold formed by said sewing a rigidifying slat can be slided in longitudinal way, wherein the profile has eyes or orifices, made for guiding said pulling cords.
  • the slat-like rigidifying profiles will be pulled up by said cords and there will be formed a group of folds or pleats of shade material falling over eachother, resulting in a funny aesthetical look of said shade.
  • the disadvantage of the known shade is the work involved necessary to slide the slats in the profile wherein further the aesthetical look is wrong as the profiles are suspended downwardly.
  • the invention has for its object to avoid said disadvantage and it provides a shade, distinguishing in that the web is clasped in such a way that a web portion at the upper side of the clasping is outwardly offset with respect to the web portion at the lower side.
  • the invention is further related to a profile suitable for a retractable shade, as described above, wherein the profile can be formed in a single or double embodiment.
  • the profile is channel-like and provided with a protruding ridge-like element, eventually formed integrally with said profile, wherein a guiding eye or orifice is arranged. Having a longer profile it is also possible to form the lips into a continuous ridge, so being able to manufacture said profile by extrusion. In order to obtain said offset clasping of the material-web and to carry out the guiding of the pulling cords along the lip-like elements or ribs as friction-less as possible, it is preferred to provide an angularity between the lip-like element or rib and the longitudinal center plane of the channel-like profile, being smaller than 180°.
  • the clasping means can be a lock-up profile snugly fitting into said channel-like profile, for instance a rod, said rod being a separate profile or being formed as integral portion of the channel-profile.
  • the invention is also related to a method for folding the web of material for a shade as described above, by means of a channel-like profile without or with a lock-up profile, wherein a strip of the web is brought into the open channel, and whereupon the lock-up profile can be pushed in said channel so clasping the web of material.
  • reference numeral 1 is related to the web of material, the width and the height thereof is dependent on the dimensions of the window R, in front of which the shade is suspended. It is clear that herebelow the "phrased” shade is to be used for all possible embodiments of partition means and the shade according to the invention is not only meant for curtains for windows.
  • the shade 1 is suspended at the upper side to a first or upper border 2 and is provided at the lower side with a second or lower border 3, which is fixed thereto.
  • the upper border 2 can be a separate beam, but it can also be the upper beam of a window for the glass panel in a building B.
  • the shade in figure 1 comprises one web of material having a width which is folded over the full length thereof at the lines 4, which folds or pleats can be formed by means of the profile as illucidated herebelow.
  • pulling cords 5 are arranged, which are fixed to the lower side to the lower border 3 and are guided along or in the upper border 2 to the right and continue in the downward hanging end portion 7, which can be manually seized by the user.
  • the shade will be pleated as depicted in figure 1 and 2b.
  • the folds 4 are formed by sewing together a strip of web-material 1. There is obtained a back-like element, in which a rigidifying profile can be received.
  • a profile is shown for replacement of said fixation, said profile, as depicted here, comprises a channel-like profile 10, having a Q-like cross section.
  • This channel-like profile 10 is provided with a continuous lip-like element, as rib 11, located at the side of the window R and wherein holes 12 are provided, serving as guiding eyes for the cords 5.
  • a lock-up profile in the form of a cilindrical rod 13 snugly fits in the space of the channel-like profile 10 and it is adapted to be pushed into said channel-like profile in the direction of the arrows P1 or P2 respectively.
  • the outwardly protruding lips 14 of the channel-like profile 10 has to be sufficiently flexible in order to spread apart during inserting the lock-up profile 10.
  • the cords 5 are guided through the eyes 12 and it will be clear that pulling up the cords 5 the lower border 3 will be pulled up against the superposing rib 11 and channel-like profile 10 directly thereabove. Pulling up further leads to a situation wherein the ribs 11 and profile 10 are laying upon eachother as depicted in figure 2B. The parts of the material-web 1 inbetween, will be folded as depicted in figure 2B.
  • the rib 11 is placed under a certain angle with respect to the longitudinal middle plane L-L of the channel-like profile 10, which angle is smaller than 180°.
  • figure 3 shows a short profile, suitable for locally folding the material-web, so obtaining a variant of the straight fold 4.
  • Figure 4 shows an embodiment, wherein the lock-up profile is integrally with the channel-like profile 10, said lock-up profile 13 can be folded up in the direction of arrow P3, see the broken line.
  • the web of material is not folded around the lock-up profile 10, but clasped inbetween the profile 10 and 13 respectively.
  • the embodiment according to figure 5 is comparable with the embodiment according to figure 1 and 2 respectively.
  • the lip-like element 11 is replaced by a separate strip having rounded edges, which can be connected to a second channel-like portion of the main profile 10.
  • the profile 10, 11 can be provided with a second main profile 10, so forming a double profile suitable to be used in the embodiment according to figure 6.
  • the profile is embodied in a double configuration, comprising two channel-like profiles 10, 10' mutually connected by a common rib 11 such that the profiles 10, 10' are arranged mirror-symmetrical to eachother. Also said rib is here provided with orifices 12 through which the pulling cords 5 are guided.
  • two material-webs 1, 1′′′ are necessary, each can be manufactured of arbitrary and/or different material.
  • Those material-webs 1 are brought into the channel-like profiles 10 in the way as described hereabove, by means of a lock-up profile 13, 13'.
  • the profile according to figure 6 has a downwardly directed mouth of the channel-like profile 10, 10'. Therefor a desired trapezoidal shape of the curtain is obtained.
  • the profiles 10 extend parallel to the lower and upper border respectively.
  • FIG 7 a variant is shown.
  • the profiles 10 are here arranged radially starting from a center point C in the mid of the upper border of a shade 1 suspended thereunder.
  • the upper shade 21 comprises here a pair of segment of a circle, which can be closed from the open position in the direction of the arrow P3. During the closing the profiles 10 turn around the center C and will be pulled up against the first border, a upstanding beam 20.
  • the profiles 10 in the embodiment according to figure 1 do not need to extend over the full width of the shade.
  • figure 8 a variant is shown.
  • the web of the shade is here devided in three web portions located adjacent to eachother in which the profiles 10 extend over a single web-like portion only. Moreover, they are offset to eachother, so obtaining a particular pleated appearance.
  • tensioning cords along which the second or lower border is to be shifted by means of the hand grip D are formed by a cord starting at E, which is led through the lower border to the right web portion, further through the eyes to the upper border and therethrough in a mirror-symmetrical way back to point E.
