Connecting element for tensile and detachable clamping or pressing, especially of two plates

Description

The invention relates to a connecting element for tensile and detachable clamping or pressing, in particular of two plates, according to protection claim 1.

To force-fit two panels together, connecting elements are often used that are designed to create a clamping, pressing or locking connection between the panels to be connected. Such clamping, pressing or locking connections should be easy to release on the one hand, and on the other hand enable a connection that is as strong and stable as possible.

For example, US 4,752,150 discloses a locking connection with which a first plate is connected to a second plate by means of a hook and snap construction. The first plate is provided with a hole into which a base body is pressed to fit precisely. This base body contains a hook mechanism that can be locked into a corresponding counterpart in a second plate.

This mechanism is complex to manufacture and therefore expensive. In addition, a press connection in the sense of an adjustable mechanism cannot be implemented in either plate one or plate two.

EP 0611 002 A1 also discloses a plug-in or snap-in connection which, with the aid of a drive-in dowel and a snap-in inside the dowel, connects a plate to a second plate with a corresponding counterpart by plugging.

These connections cannot be re-tensioned and do not result in any measurable compression of the panels. A large installation depth or panel thickness is required. In addition, with both patents, the hold in the panels is only guaranteed by the oversize of the base body or the dowel compared to the drill hole. Worn-out holes provide little or no hold for the systems.

The object of the present invention is to provide a connecting element for tensile and detachable press or clamp connection, in particular of two plates, which on the one hand requires a small installation depth and on the other hand to create a stable connection with corresponding compression forces between plates one and two for a wide variety of applications, whereby the fastening in plate one in itself also fulfills this requirement (M/GRS-024-DE).

(htOA U

This object is achieved by a connecting element with the features of claim 1. Preferred embodiments of the connecting element can be found in the dependent claims.

The core of the invention is a connecting element that has a base body with a dowel-like structure (see M/GRS-024-DE). On the top there are two opposing jaws, each of which houses two sliding blocks and guides an eccentric bolt when a panel with a hole open towards the edge is inserted in such a way that the eccentric bolt automatically secures the inserted panel against accidental removal. By pressing down a lever on the inner jaw of the eccentric bolt, a preload or pressure can be generated between the first and second panels.

A tensile clamp or press connection is created without the need for any tools.

The connection can be released by pushing away the catches within the sliding gates with the help of a screwdriver and returning the lever to its original position.

The press connection is particularly suitable for thin panels on both sides, preferably from 6 mm, which can also withstand dynamic loads, preferably through the guidance of the opposing, stable jaws. Furthermore, only simple holes are required on both sides. Undercuts and undercuts in the holes are not necessary because the eccentric bolt is pressed against the hole with force.

Both plates are press-fitted with a pre-tensioning force that can be checked and adjusted. This makes it easy to compensate for loosening caused by wear, particularly when dynamic forces are applied to the drill holes.

The connecting element according to the invention can be used advantageously in various areas, such as in furniture construction for connecting panels of all types and designs, in caravan and mobile home construction, exhibition stand construction or ship interior construction. The connecting element creates such a stable press connection that it can also be used in container construction, shop fitting, light metal construction, acoustic construction or plastic construction, i.e. areas of application in which the connection can be subjected to particularly high loads.

In addition, the opposing jaws on the base body together with the guide slots reliably cover the holes on both sides of the plate and enable an attractive appearance that can set design accents through appealing surfaces, such as colored or chrome-plated, etc.

The advantage of the connecting element is that it can be assembled without tools and is suitable for automated and CNC-compatible processing in industry. Overall, the result is an easy-to-produce press connection between two panels that differ in thickness and type, with corresponding assembly time savings, increased pull-out values and correspondingly high cost-effectiveness.

Finally, the base body with the dowel claws and the locking bolt, the jaws with the sliding gates, the eccentric bolt with the lever are made of plastic or metal or composite materials. Plastic versions can be produced inexpensively using injection molding, for example, while a metal version is particularly resilient and stable.

Further advantages and embodiments of the invention are given in the following description in conjunction with the drawings. In the drawings,

Fig. 1 shows a cross-section of the clamping or pressing connection of two plates of different thickness and/or type (10) and (20). The first plate (10) has a hole (11) with a depth of 6 to 7 mm. The second plate (20) has a through hole (21) that has been placed at the edge of the plate at an appropriate distance. This creates a precisely defined opening (39) at the edge of the plate.

The fastening in the first plate (10) is described in detail in M/GRS-024-DE. ^ (^(j COO O^t ^l At»

The edge of the plate (20) is pushed between the jaws (18, 18') in such a way that the hole (21) is located exactly above the eccentric bolt (22). The wall of the hole (21) presses against the eccentric bolt (22) and causes the eccentric bolt (22) to inevitably perform the movement (38) and (36) along the sliding blocks (33) and the deflector (35), as well as with the help of the sliding bolts (34), while overcoming the locking resistance (37), and automatically locks the plate (20) against accidental removal.

The connection can be released by pushing the locking teeth (24) aside using a screwdriver or similar tool.

Fig. 2a shows an isometric view of the open system without plates (10) and (20) to better illustrate the function. Here, the movement (31) of the locking bolt (14) can be seen, which takes place when the plate (10) is pushed in and presses and pushes the dowel claws (13) and (13') outwards and against the hole (11) of the plate (10) with the help of the webs (29).

The jaws (18) and (18') provide additional lateral support and resistance to shear forces. The base plate (16) connects the jaws (18) and (18') to the dowel claws (13) and (13') using the connecting bars (29).

Fig. 2b shows an isometric view of the locked system with the plates (10) and (20).

The sliding gate (33) is open at the top and has a slightly narrowed connecting channel (40) to the lower sliding gate (33) in the lower third, which enables easy and automatic pre-assembly of the eccentric bolt (22)

The lever (26) can be moved in direction (30) and generates a pressure against the plate (10) with the help of the eccentric bolt (22), the locking teeth (24), the sliding bolts (34) and the sliding guides (33). The plates (10) and (20) are connected in a tension-resistant manner with an adjustable pressure.

Fig. 3 shows an isometric image as an overall view of the system. Here, the projection of the eccentric bolt (22) above the jaws (18) and (18') can be seen, which enables the movement (36) and (38) in (Fig. 1) within the bore (21).

A further advantage of this connecting element is that tolerances of the bore (11) and the thickness of the first plate (10) as well as the bore in the plate (20) can be accommodated to a certain extent by the design of the dowel claws (13) and (13') and the eccentric bolt (22).

When using the connecting elements, no tools are required for assembly. The connecting element can be processed by hand or by machine, particularly from a magazine.

All details of the invention disclosed in the description of the figures are claimed as essential to the invention.
