DE3317031A1 - Clamping apparatus - Google Patents

Abstract

The invention relates to a clamping apparatus consisting of an upper and a lower part, for flat and, within certain limits, flexible articles such as films, textiles or paper. It is so designed, in two parts, that an upper part can be tilted relative to a lower part into the clamping position and out of the latter, clamping parts being provided on one side and fixing devices, such that the clamping apparatus is fixed in both positions, being provided on the other side. The upper part is preferably designed as a shallow spherical shell which covers the lower part in both positions.

Clamping device

The invention relates to a clamping device consisting of an upper part and a lower part for flat and flexible ones Items #

Such clamping devices are in various forms known, e.g. clothespins, which encompasses a whole category that uses feathers, i.e. is made up of three parts.

An older patent application, however, discloses a clamping device, which also consists of two parts and is intended for the curtain of bathrooms, showers to fix. In addition to a base body, it has an angle lever as a clamping means, which-so not in the idle state in the clamping position - almost perpendicular to the base body sticks out.

Of course, this has the serious disadvantage, especially in the bathroom, that you have to use this protruding angle lever can easily injure after loosening the clamp. Because of this fact, this clamping device cannot either used elsewhere.

The object of the invention was therefore, not only for this but also to develop a clamping device for other purposes that is flat in all positions and none has protruding parts, so that they can also be used in drawing, architecture, etc. as a holder of drawings, flat Patterns and the like can be used and the inherently practical but expensive magnets are practically unnecessary can·

The invention achieves this in that the upper part and the lower part are mutually tiltable about an axis that on the one side of the clamping device clamping parts and on on their opposite side fixing parts are provided which fix both parts in their two positions.

As such, both parts of the clamping device can have an approximately rectangular outline, such as, for example be designed like a bracket; the advantage of the new clamping device, namely no protruding parts, Having no additional spring etc. can also be achieved in such a design.

According to a preferred embodiment of the invention, however, both parts of the clamping device are different educated; the lower part can retain its rectangular shape, but the upper part is preferably flat spherical jacket formed, which accommodates the lower part and covers it in both positions, This is an obvious advantage because, according to j on the outside only the spherical cap can be seen, which can be kept very flat and no protruding parts

having. These and other features are based on the claims, the schematic drawings and the description; show it:

Fig. 1 the upper part,

2 shows the lower part of the clamping device,

3 shows the clamping device in the clamping position,

Fig. H the clamping device in the rest position and

Figure 5 is a horizontal section through the clamping device.

The upper part 1, like the lower part 2, can have a rectangular plan; Fig. 5 indicates that the Clamping device is preferably flat spherical. It has a pivot bearing 10 around which the Upper part 1 can be tilted about lower part 2, which has a corresponding bearing 20. Both parts have abutments, which are matched to one another and work together in such a way that the tiltable upper part 1 is fixed in both positions

Thus, the upper part 1 has one or more cams 11 which protrude into the interior of the upper part and on their free ends are rounded, so that the nose 21 of the lower part 2, slightly resilient, over these cams 11 can slide and come to rest in the clamped position over them and in the rest position under their tip.

On the opposite side, the upper part 1 has ei- j NEN edge 12 against which the counterpart 22 of the lower part 2 can apply in the clamping position. Further the upper part 1 has an inner web 13 at this point, which lies opposite the groove 23 of the lower part.

The outer contour of the upper part 1 has recessed grips i4 which are assigned to the fixing and clamping devices just described in such a way that the upper part 1 tilts about its axis (10, 20) when pressed at these points. The lower part 2 has a self-adhesive strip 2h , with which it can be attached to a wall, a board or the like. can attach.

The clamping device works as follows:

If a flat, flexible object 3 is to be clamped, it is pushed into the clamping device until it, as indicated in FIG. H , protrudes beyond the transverse groove 23; then a pressure is exerted on the right trough, so that the upper part 1 tilts about its axis (10, 20). The following happens:

The nose 23 slides using their elasticity over the crest of the cam 11 across and lies against the upper edges of these cams, so that the upper part 1, is held in the Klemmst RECOVERY _o At the same time the object 3 again between the two edges 12, 22 and clamped to the other by the web, so that

it cannot be pulled out again by force. If the object is to be released, 1 * 1 is pressed on the left recess, which causes the nose to be opened while tipping 21 again, but in the opposite direction, slides down over the top of the cam 11

It is important that the fixation of the upper part 1 in the clamping device is exact, whereas it can be relaxed in the rest position, i.e., can be moved within small limits.

Both parts can be made of plastic, at least the nose 21 of the lower part 2 being made of one material should, which has elasticity within certain limits; the nose 21 must namely in the lateral direction give in, but it must not buckle when pressure is exerted on it «

In principle, the following features are important:

The clamping device must be flat, both parts can have the same or different floor plans, whereby the upper part covers the lower part in such a way that there are no protruding parts.
