Problems solved by technology

[0007] However, the additionally required restoring element and its fastening on the plate element cause additional manufacturing and assembly effort.
Furthermore, the reset element and its fixation on the plate element increases the overall size of the protective cover when the protective cover should be pushed to its minimum length
[0008] All this makes such a protective cover expensive to manufacture and relatively expensive

Embodiment Construction

[0042] figure 1 A schematic diagram showing a part of a protective cover according to an embodiment of the present invention. Firstly, three protective cover sections 1 can be seen, which are telescopically displaceable relative to one another and alternately in the horizontal direction with respect to the drawing. The protective cover section 1 each has a covering leg 2 and a supporting leg 3 .

[0043] The protective cover sections 1 are connected to one another in a manner known per se by means of web-shaped connecting elements or bellows 4 .

[0044] According to the invention, however, the material of the connecting element or of the bellows 4 is designed to be inherently rigid or rigid against bending. Furthermore, the fastening of the bellows 4 to the support leg 3 is designed such that height ranges h and h' result, along which or within which the bellows 4 faces the corresponding support leg 3 connected in shape.

Abstract

The invention relates to a protective cover, comprising a plurality of protective cover segments (1), which can be moved in relation to one another telescopically and which each have a covering leg (2) and a supporting leg (3), and comprising a connecting element or bellows (4). When the protective cover is telescopically extended, an elastic restoring element produces a torque (M) and transfers said torque to the supporting leg (3). The invention is characterized in that the elastic restoring element is an integral component of the connecting element (4), in that the connecting element (4) has flexural rigidity and is connected to the supporting leg in a planar manner along a height range (H) of the supporting leg (3). Because of the invention, an additional elastic restoring element and the fastening thereof to the supporting leg are no longer necessary. Thus, the fully compressed size, weight, and production complexity of the protective cover can be reduced, and the leak-tightness and operational reliability are improved.

Description

technical field [0001] The invention relates to a protective cover according to the preamble of claim 1 . Background technique [0002] Protective covers of the type mentioned at the outset are used, for example, in machine tools to protect movable parts, such as drives, etc. Media or other components and particles cannot leave or enter in a way that endangers users and / or contaminates other machine areas. [0003] Conventional protective covers of this type have protective cover sections in the form of substantially L-shaped plate elements, which are telescopically displaceable relative to each other, whereby their legs rest on each other behind. Then, a substantially closed, movable and variable-length cover is formed. [0004] Since the covering legs which overlap one another are only stacked as loosely as possible, usually either an insufficiently tight closure is possible or structurally complex replacements have to be carried out. Such protective covers are therefor...
