Abstract

The winding shaft bearing can be moved in a horizontal direction via sliding guides (5).

Description

Rollable door with sliding tree.

The invention relates to a roll-up door or a roller blind with slats that move in rails of lateral displacement and that form a shell, which can develop or roll through a rotating tree, being housed the tree at its ends scrollable in the horizontal direction

Rolling doors or rolling shutters of this type are known. To allow in the development of the shell an at least approximately vertical entrance of the shell in the input hopper arranged above the rails of side roller, the tree must be able to move during development in the horizontal direction towards the rails of rolling During the winding the shell goes away, so opposite, of the raceways. This move is allowed. thanks to a horizontal displacement of the housing of the tree.

According to the state of the art, for example, the DE 41 05 975 A1, this horizontal displaceability is achieved by a roller housing of the door shaft Rollable or roller blind. The support plates on the that the ends of the tree are rotatably arranged, they are fixed on support plates, which have rollers that are Guided in lanes. However, this entails costs of relatively high manufacturing and assembly effort considerable. In addition, the construction unit thus carried out occupies virtually all available space on the lid of coating, so that it is barely possible to fix other groups, e.g. eg limit switches.

Document DE 22 61 311 A1 describes a sliding device for housings of rolling surfaces, in which a bearing support mounted on a socket is provided Sliding, which is scrollable in the directions of the arrow on the guide base, being made of the socket self-lubricating plastic slide. However, this arrangement, in which the guide base is primarily arranged in the horizontal direction, it has a very large construction, of so that due to lack of construction space it is impossible to place insurance to prevent falls and, if necessary, an engine between the Roller shutter breastplate and lining lid.

The object of the invention is therefore create a roll-up door or a roll-up blind according to the preamble that can be manufactured more economically and mounted more easily.

This objective is achieved according to the invention. because the tree housings are movable in the direction horizontal by sliding guides fixed on the covers of Rolling door liner or rolling shutter, the sliding guides being formed, respectively, by a sliding element wrapped by a staple-shaped plate, in which it is movable in the longitudinal direction.

Within the framework of the invention it has been found surprisingly that the horizontal displaceability of the tree of the Rolling door or rolling shutter can be performed more economically with sliding guides. Against the expert prejudices, a sliding guide can absorb tree forces that occur in a rolling door or a roller blind without tilting, and this with lower costs for the guide than in the known rolling guides. In addition, the assembly of the slide guide is simpler than that of the rolling guide and sliding guide requires less space in the lining cover, so that they can be accommodated without Problems other additional groups.

A variant of the invention provides that tree housings are arranged on support plates that they are fixed, in turn, on the support plates of the guides glide.

Finally, an embodiment of the invention provides that the slide guides ascend an angle? between 1 and 10º away from the raceways.

Next, an example of embodiment of the invention with the help of the drawings:

They show:

fig. 1, a lining cover with a guide of the tree according to the invention at the beginning of the movement of winding in a plan view from above,

fig. 2, the arrangement according to fig. 1 at the end of the winding movement,

fig. 3, a side elevation of fig. 1 and 2,

fig. 4, a view of a detail of the tree guide.

As can be seen in fig. 1 to 3, a shell 1 of a rolling door or a rolling shutter formed by splints are fixed on a tree 2 and rolled or developed by rotation of the tree 2. The shell 1 enters through an input hopper 3 on travel lanes 4. Since at the beginning of winding movement (fig. 1) few are still arranged slats in tree 2, to ensure at least one entry approximately vertical of shell 1 on guides 4, this tree It should be arranged relatively close to the guides.

However, since this position only would allow the accommodation of a reduced number of tablets in the tree 2, tree 2 moves along the movement of winding in a fundamentally horizontal plane of the raceways 4 (fig. 2).

This is allowed according to the invention by guides of sliding 5 arranged primarily in the direction horizontal, in which the tree housings are arranged 2. It is recommended that the sliding guides 5 ascend a angle α between 1 and 10 ° away from the raceways Four.

The sliding guides 5 are fixed in the lining caps 6 and have a support plate 7 in the which is in turn fixed to the support plate 8, which carries the tree housing 2.

In fig. 4 you can see in detail the structure of the sliding guides 5. A plate 9 in the form of Staple, smooth wraps a sliding element 10 with a coating 11 to reduce friction on both sides, so which is only mobile in the longitudinal direction of the plate 9. The sliding element 10 has a support plate 7, in the that in the present example the support plate 8 is arranged.
