The invention relates to the boot the door, formed by panels that can be folded, curled up, installed next to ensure that the auto transmission is th or to act as a protective curtain shops or other similar tasks.

Known boot door, containing interconnected by a transverse beam rack with rails and panels, interconnected power rods mounted for movement along the guides.

The disadvantage of the boot door is the inconvenience of its operation and the lack of unreliability in the case of strong shock loading device on the panel.

In Fig. 1 shows a General view of the described boot door; Fig. 2 is a vertical cross-section in Fig. 1; Fig. 3 is a schematic view of a variant of the loading door; Fig. 4 is a vertical cross-section in Fig. 3; Fig. 5 is a concrete implementation of the panel in the boot the door; Fig. 6 - element panel (spar), and Fig. 7 is a cross-connection panel of Fig. 8 and 9 are views in cross section of an example of the swivel of Fig. 10 is a view in cross section showing the mounting plates between the side members via a flexible shaft.

The boot door has two vertical side uprights 1, 2 the upper ends of the horizontal support beam 3. Racks have in cross section the General shape and each have a vertical guide 4. Rack and yoke designed to be placed around the doorway so that the door obespechivat panels 5, pivotally fastened together by two, with horizontal cylindrical hinges crossed by the axis. Axis represents the power terminals 6, 7, each second of which is continued inside the guide, starting from the bottom with the rod 7. Length of panels equal to or slightly less than the width of the door, i.e. have the distance between the posts 1, 2, so that these panels could form between the posts. Opening doors is provided by lifting the bottom of the rod 7, the ends of which continued in the guides to ensure their directions. The lower rod can be raised with the help of tapes secured to the lower rod and wound on a special shaft, located, preferably in the upper traverse.

When the fake tapes rod 7 rises, forcing the two bottom panels overlap each other, however, the hinge pin 6, which connects them and whose length is such that its ends are not included in the guides 4 racks, departs from the plane of the door. Then, the lower rod rack rests on the upper rod, the ends of which are entered into the guides and begins to lift him up to the moment when the panels are stacked on each other in the upper part of the door, as shown in Fig. 2.

In Fig. 3 vertical side posts 1 and 2, is made with the guides, which extend upward horizontal or inclined guides 8 and 9, respectively. Panel 5 pivotally interconnected at around two power rods 7, which extend into the guide. To open the door, simply pull up the top panel 5, which will pull up the door panel.

In Fig. 4 vertical side posts 1 and 2, with each guide 4, in which the slide panel 5 is fastened pivotally with each other. In the process of opening the door panel 5 are stacked above the door.

In addition, the use of the invention is not limited to vertical lifting doors: panels can slide horizontally in the lateral direction.

In Fig. 5 shows the panel 5, each of which has two parallel side member 10, shown in more detail in Fig. 6. Each side member 10 has two opposite edges of the fastening means in the form of a dovetail 11 and one or more longitudinal grooves 12.

The two spar 10 of each panel 5 are connected, at least two transverse links 13 is raised, which takes the profile 11 of the type dovetail of the spar 10. Additionally, in Fig. 7, the cross-link 13 has one or more longitudinal grooves 15 on two oppositely located sides, agreed with longitudinal grooves 12 of the side members 10.

The side members 10 and cross connection 13 form a frame, the holes which may be provided with a flat rigid plates filling 16, which may be made from plastic, wood, for example with a coating of glass, metal, etc. Plate filling 16 can slide in the grooves 12 and 15 of the side members and cross-linking. Plate filling 16 can be fixed using flexible peripheral edges 17, having a H-shaped profile, as shown in Fig. 10. The rim 17 is inserted, on the one hand, in the side members 10 and cross connection 13, and then takes a well-known fashion plate filling 16.

In addition, the side of the side member 10 opposite to the cross ties 13, receives the hinge elements 18 and 19, shown in detail in cross section in Fig. 8 and 9. Each element 18 and 19 has a groove 20 type dovetail, which allows its holder on the profile 11 in the dovetail rails 10, side rails, directed the every spar 10, and each element 18 panel 5 front element 19 adjacent panels. In a special example in Fig. 5 panel 5 is hinged on two power terminals 21, of which at least some slip in the stationary side rails, as explained above with reference to Fig. 1-3. The elements 19 cross rods 21, whereas the elements 18 fill the space between the panel 5, where they are fixed and the element 19 opposite.

When the panel 5 is not connected pivotally by two, as shown in Fig. 4, each panel 5 may be attached to the two power terminals 21 with a hinge joints 19, cross rods, or any other means of fastening.

In all cases, it is desirable that the ends of the power rods 21 which slide in stationary guides the door could be broken before constantly could be destroyed or deformed other details in case of shock overloading mechanism on the panel. Thus, the panel can be released without considerable damage. For example, the reinforcement rods 21 can have a cross-section of least resistance between the edge of the panel and the rail. In the embodiment, the terminals can be dostat the governmental form of implementation of the invention, the profiles in the dovetail 11 of the side members 10 have a sufficiently small cross section to break during strong strike for example, when the boot device gears panel 5. Thus, the panel shifted, and other panels are not at risk to be damaged. It is possible that only adjacent edges of adjacent panels are at risk of damage. Needless to say, the cross-section profiles in the dovetail 11 should still be sufficient to panel 5 resisted the weather (wind) and hacking attempts.

In another preferred form of the invention the side members 10, cross connection 13 and the hinge elements 18 and 19 collected exclusively by friction, without gluing, welding, and have a flexibility sufficient to profiles in the dovetail 11 out of the grooves in the dovetail 14 and 20 in the process a strong impact on the panel 5, for example, because of the handling device. Thus, the panels are split up, which limits the destruction of this panel, and possibly the adjacent edges of adjacent panels. As before, needless to say, the panels are resistant to weather (wind) and hacking attempts. (56) USSR Author's certificate N 939706, CL E 06 In 9/00, 1980.
