Description

The present invention relates to a connecting device for releasably connecting plate-shaped wall elements, the connecting device having a receiving body and a connector body and the connector body having a base body and at least one connecting bolt arranged on the base body and insertable into a recess of a wall element and the receiving body having at least one with a Has interior space and an opening provided, which can be inserted into the recess of the wall element and receives the connecting bolt at least along a portion of its longitudinal extension, according to the preamble of claim 1. The invention also relates to a partition according to the preamble of claim 11.

The connecting device can be used to set up a partition, which can be, for example, a mobile partition, as is often used in trade fair construction. The partition can be part of a system which uses different wall elements to form the partition.

Partition systems of the usual type have wall elements with corner holes and connectors as a flat plate with several bolts. In order to prevent the connectors from twisting, connectors with pairs of bolts are usually plugged into the wall corners. Usually the wall corners then have two bores and the connectors have four bolts. The wall elements are rigidly connected to one another. In order to build different wall floor plans with different angles, different angle connectors, end connectors, T-connectors and corner connectors are usually used. This means that different connector variants are necessary even for right-angled wall layouts. The material must be kept available. In such simple bolt wall systems, the lower connectors easily fall out during insertion, assembly and conversion. The falling out of the lower connector on a partition wall constructed in this way can be prevented by elastic parts on the bolts.

A connecting device for forming such a partition is for example based on DE 20 2015 001 588 U1 known.

In addition, the WO 92/21832 A1 a device for releasably articulated connection of panel-shaped wall elements has become known.

The object of the invention is to improve the known connecting device, in particular to provide a simply constructed, inexpensive and easy to use and stable connecting device which prevents the connecting device from accidentally falling out of the wall elements. The connecting device to be created should also make do with a few parts.

A partition with the connecting device to be created should also be provided.

In order to achieve this object, the invention has the features specified in claim 1 with regard to the connecting device. Advantageous refinements thereof are described in the further claims. In addition, the invention has the features specified in claim 11 with regard to the partition to be created, an advantageous embodiment thereof is specified in the further claim.

The invention creates a connecting device for releasably connecting plate-shaped wall elements, the connecting device having a receiving body and a connector body and the connecting body having a base body and at least one connecting bolt arranged on the base body and insertable into a recess of a wall element and the receiving body having at least one with an interior space and a receptacle provided with an opening which can be inserted into the recess of the wall element and receives the connecting bolt at least along a portion of its longitudinal extension, the receptacle having elastic elements which surround the interior space at least along a portion of the circumferential extent of the interior space.

The receptacle body can be arranged on a panel-shaped or plate-shaped wall element in such a way that the receptacle having the interior space and the opening is received in a recess of the wall element. The interior of the receptacle is accessible through the opening; the opening can be a passage opening for the connecting bolt of the connector body to be received. If the connector body with the connecting bolt is arranged on the receiving body arranged on the wall element, for example by means of a dowel or a screw element, then the connecting bolt enters through the opening into the interior of the receiving body, so that the bolt is also arranged in the recess of the wall element is located. The bolt is thus arranged in the interior of the receptacle which, starting from the opening, extends into the space arranged between the elastic elements extends and can also extend beyond that.

Since the receptacle has elastic elements, which can be, for example, two mutually associated elastic elements in the form of spring tongues which, when the connecting bolt is inserted through the opening into the interior of the receptacle, move away from each other, i.e. away from the connecting bolt For example, they are pressed radially outward and thus come into contact with an outer circumferential surface of the connecting bolt and are frictionally engaged there and exert a holding force or spring force on the connecting bolt due to the elastic design of the elements, so that the connecting bolt does not automatically, i.e. not unintentionally, move out of the receptacle can fall out, which is particularly advantageous if the connecting device is arranged on wall elements on an end face on the underside of the wall elements and could thus fall out due to the force of gravity.

The connecting device according to the invention prevents such an unintentional falling out of the connecting bolt (s) from the receptacle of the connector body even if a mobile partition created with the connecting device according to the invention is moved with, for example, two or more wall elements, for example when building a trade fair.

According to a further development of the invention, the elastic elements, which can be two or more elastic elements, are arranged on a base body of the receiving body, that is, for example, are formed in one piece with the base body, and the opening leading into the interior of the base body and are arranged at a distance from one another.

The elastic elements then give way radially outward when the connecting bolt is inserted into the interior of the receptacle and lie against the outer circumferential surface of the connecting bolt and apply a holding force to the connecting bolt which results from the elastic deformation of the elements.

The connecting bolt can simply be pulled out of the receptacle again, but does not fall out of the receptacle automatically in an unintentional manner. This process of inserting the connecting bolt into the receptacle of the receiving body and pulling the connecting bolt out again can be repeated, so that the above-mentioned partition with the connecting device according to the invention can be set up and dismantled again as often as desired.

The elastic elements act on the connecting bolt or bolts and thus reversibly clamp the connecting bolt in the receptacle.

According to a further development of the invention, provision is also made for the elastic elements to be designed as spring tongues and to have a contact surface facing the interior, on which the connecting bolt can be releasably brought into contact.

The connecting bolt thus slides along the contact surface when the connecting bolt is inserted into the receptacle of the connecting body and ensures that the spring tongues are pressed slightly radially outward so that they apply a spring force to the outer circumferential surface of the connecting bolt and thus frictionally engage the connecting bolt in the interior of the receptacle clamp.

According to a further development of the invention, it is also provided that the opening leading into the interior has a configuration deviating from a circular configuration in a plan view.

This development of the invention leads to the advantage that a locking bolt penetrating the opening, which is designed to complement the opening in shape and area at least on a portion of its longitudinal extent on the outer circumference, is non-rotatable in the opening with regard to any twisting movement of the locking bolt in the opening, in particular is positively rotationally fixed, and is thus further prevented from accidentally falling out of the opening. An unimpeded rotational movement of the locking bolt in the opening can namely lead to the bolt or locking bolt falling out of the opening being promoted by such loosening of the locking bolt, which is prevented by the design of the connecting device according to the invention.

According to a development of the invention, it is also provided that the opening has a peripheral wall which surrounds the opening and the peripheral wall has a configuration that tapers in cross-section in the direction of the interior.

With this development it is achieved in an advantageous manner that a locking bolt to be inserted into the opening, which for example has to be inserted from below into a lower end face of the wall panel, can be easily inserted into the opening, since the cross-sectional tapering configuration of the opening - and the shape and surface complementary training of the locking bolt - an improved guidance during Introducing or inserting the locking bolt into the opening of the receptacle of the receiving body is achieved. This is advantageous, for example, when the locking bolt has to be inserted into the wall panel from below in the manner already described above, since the user of the locking device cannot visually check this process of inserting the locking bolt when the wall panel is at least largely vertically aligned with the face pointing downwards.

According to a development of the invention, it is also provided that the locking bolt has an elongated configuration and has a first section with a configuration deviating from a circular configuration and a second section.

The second section can be, for example, a cross-sectionally circular section. The connecting bolt can easily be inserted with this section into the opening of the receptacle of the receiving body and this section can also protrude into the interior of the receptacle of the receiving body or penetrate the interior. With the first section having a configuration deviating from a circular configuration, it is achieved that the locking bolt with this first section is, for example, positively inserted into the opening of the receptacle of the connector body and fixed there in a twisted manner. The first section of the connecting bolt is advantageously designed to be complementary in shape and surface to the configuration of the opening of the receptacle.

According to a further development of the invention, provision is also made for the first section to have engagement elements provided on the outer region for engagement with the opening, the cross-sectional area of which decreases from the base body in the direction of the second section.

With the engagement elements it is achieved that the connecting bolt or bolt or locking bolt is secured against rotation in the opening of the receptacle of the receiving body.

Because the cross-sectional area of the first section decreases from the main body in the direction of the second section, it is achieved that the outer circumferential surface of the first section tapers in the area of the engagement elements and with the tapered configuration it is achieved that when inserting or inserting the connecting bolt In the opening of the receptacle a limitation of the depth of insertion of the connecting bolt into the receptacle is achieved. As soon as the connecting bolt has been inserted so far into the opening that the engagement elements come into contact with the inner circumferential surface of the opening, the connecting bolt is automatically secured in position in the opening without the user having to check this visually.

According to a further development, it is also provided that the first section has a configuration that is complementary in shape and surface to the configuration of the opening, whereby the above-mentioned positive connection between the connecting bolt and the opening is achieved and thus an anti-rotation lock of the connecting bolt is implemented relative to the opening .

According to a further development of the invention, it is also provided that the opening has an inscribed inner circle in a plan view, on the circumference of which there are bulges extending in the radially outward direction, which are provided equidistant or non-equidistant from one another.

The bulges can, for example, provide a star-shaped, rectangular, jagged configuration of the opening in a plan view; the bulges can also be semicircular, quarter-circle-shaped or ellipsoidal and be equally spaced relative to one another in the circumferential direction of the opening or have different distances from one another.

In a similar manner to this, the respective connecting bolt on the first section is designed to be complementary in shape and surface, so that the first section of the connecting bolt can be fixed in a rotationally fixed manner in the opening of the receptacle of the receiving body.

According to a further development of the invention, it is also provided that the connector body has two base bodies which are arranged axially fixed and pivotable relative to one another by means of a joint, with at least one connecting bolt being arranged on each base body.

In this way, for example, two wall elements can be coupled to one another on the opposite end faces with two connecting devices and the inner angle or outer angle between the two wall elements can be adapted or set according to the respective requirements by means of the joint.

The invention also provides a partition with at least two plate-shaped wall elements, which has a connecting device as explained above.

Thus, the two plate-shaped wall elements can be connected to one another at the respective end faces with a respective connecting device and can be fixed in relation to one another, for which purpose a connecting device with two connecting bolts is provided, of which one connecting bolt is arranged in a receptacle of a receiving body in each wall element, and two wall elements can also be connected to one another in an articulated manner, as has been explained above.

According to a development of the partition wall according to the invention, it is provided that a wall element has at least one recess on at least one end face, which recess is designed to accommodate the receptacle of the receiving body.
