Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention has articulatingly interconnected armor plates which extend in side grooves up to an upward deflection device. Concerning a folding roll-up blind which is retractable as a stack of horizontally overlapping armor plates guided by a driveable roll-up shaft and supported at the bottom by zigzag-like folding behind this .

BACKGROUND OF THE INVENTION In this type of folding roll-up blind, the armor plate guides both side grooves and the guide grooves connected to these side grooves by means of guide pins attached to both ends of the armor plate. It has become publicly known that However, both the large number of guide pins at both ends of the armor plate and the guide grooves in both girders require significant manufacturing and maintenance costs.

Problem to be Solved by the Invention The problem to be solved by the present invention is thus to obtain a foldable roll-up blind that does not require guide pins at both ends.

Means for Solving the Problems The inventor has proposed that when the stacking of the armor plates is carried out on the bottom of its support member with care that no inclination with respect to the vertical plane is possible, the guide pin has made the surprising discovery that it does not need to be installed at both ends of the armor plate, but only at one end.

Therefore, based on this knowledge, the foldable roll-up blind according to the present invention is provided with one girder on each side of the opening of the window frame, and each girder has the following:
One bearing for the hoisting shaft and one guide groove surrounding the turning point are provided so as to be continuous with each side groove, and the armor plate is folded in a zigzag shape only on one girder. Branch grooves for guiding are provided, and these branch grooves are guided from the guide grooves formed in the girders to the bottom of the armor plate support member, and a guide pin is provided at one end of at least every other armor plate. and these guide pins are guided alternately in the branch grooves so that at least two armor plates are folded and stored as a set on the bottom of the armor plate support member. and has on both girders at least one retaining element for the armature support member extending in the height direction of the armature storage space, these retaining elements It is characterized by regulating the position of the armor plate within the member.

For reasons of finishing technology, both girders, which may themselves be divided into two parts, are provided with downwardly removable armor plate supports, for example fixed in a vertically movable manner at two levels. can be done, but it serves the purpose. Both support members may be rigidly interconnected, for example by a bottom portion which closes below a recess in the building on the house side of the roll-up blind. For the formation of the stacking guide, pairs of holding elements for the downwardly projecting support elements are provided on both girders, these pairs of holding elements comprising:
At the same time, it can also serve as an engagement member for the support member.

Embodiment In FIG. 1, reference numeral 1 indicates a lintel recess made between a window frame 2 and a lintel (beam at the top of the window opening) 3. Girders 4a and 4b each having a U-shaped cross section are fixed to both side surfaces of the lintel recess 1. In the illustrated embodiment, which is suitably made of synthetic resin, the girder 4a, 4 is made of two parts.
The upper beams 5a, 5b of b are each provided with one bearing for a rolling shaft, here a winding shaft 6, which is formed as a square roller. The drivable winding shaft 6, which is designed as a rotor by means of corner projections 6c, serves as a transport and deflection device for the armor plate 9. This armor plate 9 is guided in a normal side groove 7, which extends along the side of the lintel 3 into a lower girder 6.
guided upward along a or 6b, where
The side groove 7 adjoins a guide groove 8 which is guided into the region of the winding shaft 6 in the upper beam part 5a or 5b and surrounds the winding shaft 6 by approximately 180°. This guide groove 8 is bounded on its outer part by an arcuate flange 8a which serves as a guide for the armor plate 9 and as a safety device against its dislodgement. The shutter plate 9 of the roll-up blind is designed as a hollow shell. These armor plates 9 are articulated to each other at their longitudinal edges by connecting chains 10 passing through them and consisting of bent chain members hooked together. and have limited movement toward or away from each other. Armor plate 9 guided via the winding shaft 6
is caused by the joints of these connecting chains 10,
c, and in this way the winding shaft 6
It can be hung on the rotary ring 6c without direct contact with the rotary ring 6c. As can be seen from Figures 1 and 3, the girder 4a placed on one side of the roll-up blind
The guide groove 8 in the upper beam 5a opens behind the winding shaft 6, approximately at the height of its axis, into a branch point formed by a deflection wedge 11. The turning wedge 11 is connected to the guide groove 8
is divided into two branch grooves 11a and 11b that are guided downward to approximately the height of the upper end of the side groove 7,
From there, these branch grooves 11a, 11b are led spaced apart from each other and parallel to each other into the support member 13 in the lower beam 6a. 1
The ends of the individual armor plates 9 facing toward the upper girder 5a are provided with guide shafts at approximately half the height of the armor plates 9. Each guide shaft consists of a guide disk 12a and an end journal 12b eccentric thereto. As shown in FIG. 1, these end journals 12b
are alternately displaced so that one end journal is on the inner side and the other end journal is on the outer side when viewed from the guide pin. Guide disk 12a
are guided with relatively small play in their side grooves 7 and in the guide grooves 8 and branch grooves 11a, 11b, while the alternately displaced end journals 12b of the blind During winding, at the deflection point formed by the wedge 11, it is deflected alternately into one or the other branch groove 11a or 11b, which means that
In a manner known per se, for the zigzag-like folding of the shroud 9 away from the winding shaft 6 behind the winding shaft 6 and the folded shroud 9 downward onto the bottom of the shroud support 13. , is carried out for the formation of a stack of armor plates 9 consisting of a pair of armor plates 9 lying horizontally with respect to each other. In the illustrated embodiment, the shroud support member 13 is provided with a U that interconnects both girders 4a, 4.
It is formed by a one-piece support groove with a shaped longitudinal section, the bottom of which closes the recess 1 of the lintel below. However, the integral support groove 1
Instead of 3, it is also possible to simply provide two fixed support groove parts on each digit 4a, 4b.

The lower beam part 6a of the armor plate support member 13,
6b, the front and rear walls of the lower beams 6a, 6b, U-shaped in cross-section, have downwardly projecting, inwardly curved cross-sections and A shroud support retaining element 14 is provided which has an engaging nose at its lower end. U
The front and rear walls of the shroud support member 13, which has a shaped longitudinal section, are provided with incisions 15 spaced apart from each other. In the operating position of the roll-up blind (FIGS. 1 and 2), the shroud support 13 is pressed into its upper end position;
In this position, the engagement nose of the armor support retaining element 14 is engaged in the lower notch 15 . The height of the accommodation space for the stack of armor plates 9 formed between the winding shaft 6 and the bottom of the armor plate support 13 is in this case the height behind the winding shaft 6 when the armor panels 9 are rolled up. It is selected to be sufficient to receive a portion of the blind shutter 9. Note that in this case the lowermost shutter plate 9 of the blind is still in the side groove 7 covered by the lintel 3. However, in order to bring the entire blind armor 9 into its storage space (and thus when the armor 9 is completely rolled up by the winding shaft 6), the armor support 13 is , can be slightly lowered,
This allows the armor plate support member holding element 14 to
It is adapted to engage with the upper notches 15 in the front and rear walls of the armor plate support member 13. In this way, the entire folding blind (blind with winding shaft, girders 4a, 4b and shingle support 13) is transported as a small unit and assembled into the recess 1 of the lintel 3. broken down and decomposed.

As previously explained and as shown in FIGS. 1 to 3, the guide disks 12a, 12b as well as those necessary for the zigzag folding and thus for the formation of a stack of folded armor plates 9 are shown. The deflection wedge 11 and the branch grooves 11a, 11b are only on one side of the blind. As shown,
In this case, these guiding elements are provided in separate plastic elements, which plastic elements are located in the lower beam part 6.
It serves the purpose to be fixed in b.
It is therefore expedient to design the basic elements of both beam parts 6a, 6b identically in mirror symmetry. However, in all cases, due to the stiffness and self-weight of the armor plate 9, the part of the armor plate 9 that moves away from the winding shaft 6 is
is ensured to be folded over its length to form the desired stack of armor plates 9 on the bottom of the armor plate support 13. However, the guide pins 12a, 1 in one digit 4a
2b guarantees the correct position (both horizontally and vertically) of the stack of armor plates in the armor storage space, but the stack of armor plates that is not guided at the other end is already tilted during the folding process. It can be positioned horizontally, vertically, or slightly diagonally. This means that the connecting chain 10 projecting in the bent position between the pairs of mutually successive armor plates 9 is close to the upper corner of the front or rear wall of the armor plate support 13 and thus
This may result in preventing further lowering of the armor plate 9. In order to avoid this, of course, the front wall or the rear wall of the armor plate support member 13 has lower beam portions 6a, 6 along its entire length.
can be pulled up to the upper corner of b. However, in the case of the above-mentioned blinds, this complicated measure is such that the shingle support retaining element 14, which extends over the entire height of the receiving space of the shingle, is curved inwardly in cross section as described above. By virtue of the fact that the guide pins are not provided on the side of the armor plate, they are also avoided, since they also serve as guide ribs that ensure the correct position of the stack.

If other means are provided for the removable fixation of the armor plate support 13 instead of the armor plate support retaining element 14, corresponding
Guide ribs for establishing the stacking condition can be provided on the corresponding girder 4b (or also on the armor plate support 13) only in the region of the end of the armor plate 9 which is not guided by guide pins. Lateral sliding of the armor plate 9 (which is due to the absence of a guide disk on one side of the blind, as shown in FIG. 3) is caused by the guide disk 12a. Side grooves 7, 8 and branch groove 11
This can be prevented by narrowing the opening side of the portions a and 11b.

The above-mentioned guide pins only on one side are of course also possible in the case of folding roll-up blinds in which the stack of shingles is formed from a single shroud rather than from pairs of shingles. Yes, but
At that time, the stack is usually correspondingly higher.

Effects of the Invention The above-described folding roll-up blind is simple in construction since the guide means are provided only on one side of the shutter plate, and therefore can be manufactured inexpensively, yet still functions well. is certain. This roll-up blind also ensures that it can be folded up behind the turning point and stacked in the correct position.
