Definitions

  • the idea on which the invention is based is a pressure clamp consisting of two clamping elements which make it possible to connect any two parts T1 and T2 which are to be connected to one another by plugging and pressing together with a specific holding force.
  • the clamping elements of this pressure clamp contain elastic parts, which are shaped and arranged in such a way that they are elastically deformed when pressed together due to space requirements and thereby jam each other, but if necessary i.A. can also be removed at any time with little wear.

  • a pressure clamp consisting of two (with the exception of the head parts) the same clamping elements, called: "symmetrical" pressure clamp, and
  • the symmetrical pressure clamp is very likely to be a fundamentally new type of technical clamping principle, which up to now has apparently not been known in a similar form even in approaches to other technical fields. Because of the otherwise usual, but in this case missing comparison with already known similar arrangements, the clamping effect is almost blinding with the simplest shape and choice of material, because it is unusual. The breadth of the resulting new application options and the associated variety of different design options in terms of shape and material naturally make the comprehensive assessment extremely difficult.
  • the solution according to the invention of the symmetrical pressure clamp 85 consists of two identical clamping elements; The basic structure of one of these clamping elements is shown in drawing 1:
  • Two identical elastic legs (1) are arranged in such a way that they enclose a small angle Alfa (2). At the upper end they are non-positively connected by a connecting part (3); at the lower end, the legs are angled slightly outwards as an insertion aid (4). At the upper end, an appropriately shaped head part (5), provided with a locking pin (6) if necessary, provides a connection or locking in a conventional manner to the part T1 in question, which is to be connected to another part T2 (In the example shown, parts T1 and T2 are not shown; the 100 head part has the same locking function as the round head with a conventional round head screw!).
  • a concrete design of the clamping element of the symmetrical pressure clamp consists of a round rod made of an elastic material, e.g. a cylinder with the diameter a (7).
  • Suitable measures such as e.g. Roughening, reefing and special shaping of the legs are very much enlarged; an additional increase in both frictional forces can result from the use of ferromagnetic materials
  • the width of the clamp elements put together should fill the drill holes approximately (2d + a B); the length of the locking pins (19) and (20) must be greater than B so that the locking pins protrude beyond the drill holes and can act as a locking bar; the length of the
  • Clamping elements should be selected so that the plates can also be pressed together sufficiently when the clamping elements are pressed together, without the leg ends of the clamping elements already touching the locking pins.
  • the function of the head part is performed directly by the locking pin; in other applications, the 235 or connection function can be adapted to the special task.
  • the simplest head part after the mere locking pin is an eyelet (21) (drawing 5) bent from the same leg-round rod mat ⁇ ⁇ - al, which arises when the round rod is not simply bent into a U-shape, but

  • the two clamping elements of a symmetrical pressure clamp do not necessarily have to be assembled from several individual parts, but the individual clamping element can also only be made from a single connection and head part.
  • the two clamping elements (46) and (47) created in this way can then be rotated by 90 ° to each other, as with symmetrical pressure clamps usual, put together. If you then push a tight-fitting, stable sleeve over the 275 jammed pairs of legs, this prevents the legs from being able to bend apart under greater tensile loads. If the legs are made of metal and the sleeve is either not (yet) present or if it consists of a 280 electrically non-conductive material, the legs can, as already described above, be permanently welded to one another by a sufficiently large electrical current pulse. In this way, for example, the two ends of a solid electrical cable can be mechanically operated in a simple manner
  • the necessary space is created so that the respective pair of legs can form the required angle Alfa before being plugged together in order to generate the required elastic restoring forces when printing together.
  • Restoring force is achieved exclusively by specifying the angle Alfa that the two legs form. After spreading the two pairs of legs when printing together, all four legs are parallel to each other. There is basically another alternative to this version described up to 330:

  • the free ends of the legs must of course be tapered in a rotationally symmetrical manner (37) in order to ensure the necessary insertion aid.

  • Pressure clamps with differently shaped clamping elements are particularly large.
  • the clamping force is only ever generated with one of the two clamping elements, and here only a very limited part of the available volume is used for the actual restoring spring action (e.g. the thin push button on the push button)

Abstract

La présente invention concerne une pince de compression qui est constituée de deux éléments de pince permettant de relier deux parties quelconques T1 et T2, qui doivent être reliées l'une à l'autre, par emboîtement et compression des deux éléments de pince avec une force de rétention définie. Les deux éléments de pince comprennent des parties en forme de barres, appelées branches, qui sont placées et formées symétriques en rotation autour de leur axe de symétrie, de façon à pouvoir être emboîtées, puis, lorsqu'elles sont emboîtées et comprimées, elles sont déformés de manière élastique pour des raisons d'encombrement et sont ainsi bloquées de force l'une dans l'autre.
