Description

The present invention relates to a connecting device for the detachable connection of panel-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 a receptacle provided with an interior and an opening, which can be inserted into the recess of the wall element and accommodates the connecting bolt at least along a section of its longitudinal extent, according to the preamble of claim 1. The invention also relates to a partition wall 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 screen may be part of a system that uses various wall elements to form the screen.

Conventional partition systems have wall panels with corner holes and connectors as a flat panel with multiple studs. To prevent the connectors from twisting, connectors with pairs of bolts are usually inserted at the wall corners. The wall corners usually have two holes and the connectors have four bolts. The wall elements are thus rigidly connected to one another. To build different wall layouts with different angles, different angle connectors, end connectors, T-connectors and corner connectors are commonly used. As a result, different connector variants are required even for rectangular wall layouts. The material must be kept. With such simple stud wall systems, the bottom connectors tend to fall out at the bottom when plugging in, setting up, and remodeling. The lower connectors on a partition built in this way can be prevented from falling out by means of 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, based on the WO 92/21832 A1 a device for detachably 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, easy-to-handle and stable connecting device which prevents the connecting device from accidentally falling out of the wall elements. The connection device to be created should also make do with few parts.

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

To solve this problem, the invention has the features specified in claim 1 with regard to the connecting device. Advantageous configurations of this are described in the further claims. In addition, the invention has the features specified in claim 11 with regard to the partition wall to be created, an advantageous embodiment of which is specified in the further claim.

The invention provides a connecting device for the detachable connection of panel-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 an interior space and a receptacle provided with an opening, which can be inserted into the recess of the wall element and accommodates the connecting bolt at least along a section of its longitudinal extent, the receptacle having elastic elements which surround the interior space at least along a partial region 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 receptacle of the receiving body, so that the bolt is also arranged in the recess of the wall element located. The bolt is located in the interior of the on measure arranged, which extends from the opening starting in the space arranged between the elastic elements and can also extend beyond that.

Since the receptacle has elastic elements, which can be, for example, two associated elastic elements in the form of spring tongues, which then, when the connecting bolt is inserted through the opening into the interior of the receptacle, away from the connecting bolt, i.e for example, be pressed radially outwards and thus come into contact with an outer peripheral surface of the connecting bolt and rest there by friction and, due to the elastic design of the elements, exert a holding force or spring force on the connecting bolt, so that the connecting bolt does not come out of the receptacle automatically, i.e. not unintentionally can fall out, which is particularly advantageous when the connecting device is arranged on wall elements on an end face on the underside of the wall elements and could therefore fall out due to gravity.

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

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

When the connecting bolt is inserted into the interior of the receptacle, the elastic elements then deviate radially outwards and lie against the outer peripheral surface of the connecting bolt and apply a holding force to the connecting bolt that results from the elastic deformation of the elements.

The connecting bolt can be easily pulled out of the receptacle again, but does not accidentally fall out of the receptacle on its own. This process of inserting the connecting bolt into the receptacle of the receiving body and pulling out the connecting bolt again can be repeated, so that the partition wall mentioned above with the connecting device according to the invention can be assembled and dismantled 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 development of the invention, it is also provided that the elastic elements are designed as spring tongues and have a contact surface facing the interior space, on which the connecting bolt can be detachably brought into contact.

When the connecting bolt is inserted into the receptacle of the connecting body, the connecting bolt slides along the contact surface and ensures that the spring tongues are pressed slightly radially outwards, so that they apply a spring force to the outer peripheral surface of the connecting bolt and thus frictionally engage the connecting bolt in the interior of the receptacle jam.

According to a 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 further development of the invention has the advantage that a locking bolt which passes through the opening and which is designed to be complementary in shape and surface area to the opening at least on a section of its longitudinal extent on the outer circumference, is non-rotatably in the opening with regard to any twisting movement of the locking bolt in the opening, in particular is arranged in a form-fitting, non-rotatable manner and is thus further prevented from accidentally falling out of the opening. An unimpeded rotary movement of the locking bolt in the opening can result in the bolt or locking bolt falling out of the opening being promoted by such a loosening of the locking bolt, which is prevented by the configuration 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 cross-sectionally tapering configuration towards 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, easily slides into the opening voltage can be introduced, since the cross-sectionally tapering configuration of the opening - and the shape and surface complementary formation of the locking bolt - improved guidance when inserting 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 if the wall panel is at least largely vertically aligned and the face is pointing down.

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 section with a circular cross section. With this section, the connecting bolt can be easily inserted 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 pass through 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 inserted, for example, in a form-fitting manner in the opening of the receptacle of the connector body and is securely fixed there when rotated. The first section of the connecting bolt is advantageously designed to be complementary in shape and area to the configuration of the opening of the receptacle.

According to a development of the invention, it is also provided that the first section has engagement elements on the outer area for engagement with the opening, the cross-sectional area of which decreases starting 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.

The fact that the cross-sectional area of the first section decreases from the base body in the direction of the second section means that the outer peripheral surface of the first section tapers in the area of the engagement elements and the tapering configuration means that when the connecting bolt is inserted or inserted a limitation of the insertion depth of the connecting bolt into the receptacle is achieved in the opening of the receptacle. Namely, as soon as the connecting bolt has been inserted so far into the opening that the engagement elements come into contact with the inner peripheral 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 area to the configuration of the opening, whereby the above-described positive connection between the connecting bolt and the opening is achieved and thus the connecting bolt is secured against rotation relative to the opening .

According to a 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 are arranged radially outwardly extending bulges, which are provided equidistantly or non-equidistantly from one another.

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

In a manner similar to this, the respective connecting bolt on the first section is designed to be complementary in terms of shape and area, 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 receptacle body.

According to a 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 connected to the respective by the joint Adjusted or set according to requirements.

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

The two plate-shaped wall elements can be connected to one another at the respective end faces with a respective connecting device and fixed in relation to one another, for which purpose, for example, 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 explained above.

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

The invention is shown and explained below in different embodiments based on various exemplary embodiments of the connecting device with receptacle bodies and connector bodies with openings in the receptacles of the respective receptacle body and connecting bolts of the respective connector body. In particular, the openings of the receptacles of the receiving body and the connecting bolts can have different configurations and/or inner contours and/or outer contours.

The connector body 200 of the connecting device 400 has a main body in the form of a longitudinal plate 21, the longitudinal plate having a connecting bolt or bolt 22 at both ends. The bolts 22 preferably have a round cross-section at the free end, the second section 222, and in the other part, the first section 221, a shaped, for example square, preferably star-shaped cross-section. The connector body with connecting bolts is also referred to below as a connector.

At the transition from star shape to round shape, the transitions are chamfered. The upper round part facilitates insertion into the holes or openings 303 of the base body 1 of the receiving body 300. The bolts 22 are thicker at their base near the longitudinal plate 21 than at their free ends and are made slightly conical or in two or more different sections with different thickness molded. At the free end, the bolts 22 are heavily chamfered over a short distance. So both the star-shaped parts of the bolts and the round parts of the bolts are slightly tapered towards the end. The bulge on the bolts 22 are preferably designed as a triangular bulge with a 90° tip, i.e. star-shaped points 23, but can also be steeper or flatter, or can also be designed as a rectangular bulge 24, a wavy bulge 25 or a combination thereof. The star shape preferably consists of eight protrusions in the form of spikes, but can also be in the form of a square, that is to say with four spikes or four protrusions, or have fewer or more protrusions.

The bolts have a threaded hole 14 of preferably M8 mm to accommodate extensions such as adjustable feet 13 or top bolts 12. The connector body 200 with connecting bolt 22 and base body or longitudinal plate 21 can preferably be made of a stable, slightly elastic material such as polyamide, the mentioned construction parts can also be made of other plastic or metal.

The longitudinal plate 21 is of rectangular cross section and is preferably 3 mm to 7 mm thick and preferably 14 to 30 mm wide. The longitudinal plate has a circumferential fold 27 for engaging in order to be able to remove the connectors easily.

The used in the wall panel or the wall element 8 receiving body 300 has a basis of example 3 Apparent base body or counterplate 1 and is located on all four wall corners 29 of the wall element 8 and can be molded, glued or screwed in there. The wall panels 8 are preferably 40 mm thick. The counter-plate 1 of the connecting device 400 integrated into the wall plate 8 consists of a plate with a thickness of preferably 3 to 8 mm and rounded ends.

The counter plate is chamfered on the outside edge towards the inside. The counterplate has square, preferably star-shaped openings 303 or holes 2 corresponding to the connecting bolts or shaped bolts 22, preferably there are two holes 2, but there can also be several, preferably with an inner circle 4 describing 12 mm.

Corresponding to the number of openings 303 of the respective receptacles 301, a corresponding number of round holes 28 are drilled in the wall behind the plate 1 in the wall or the wall element 8; the diameter of the round holes 28 corresponds to the descriptive outer circle 3 of the openings 303 of the counter-plate or the descriptive outer circle 3 of the bolt 22, as a result the inserted bolt 22 is additionally held stable and the overall stability is significantly increased.

The openings 303 in the counter plate 1 are preferably designed as a triangle, i.e. a star shape 23, with a 90° point corresponding to the shaped bolts 22, but can also be steeper or flatter, or could also be designed as a rectangular shape 24, wave shape 25 or a combination thereof. The star shape preferably consists of eight indentations in the form of spikes, but can also be designed as a square, ie with four spikes or four indentations, or have fewer or more indentations.

On the counter plates 1, which are mounted on the wall corners 29, small resilient parts 6 or elastic elements 6 are attached or formed on the inside, which protrude somewhat resiliently into the openings 303. Preferably, four or eight such spring parts 6 are formed per opening, but there can also be fewer or more resilient parts 6.

When connecting, the bolts 22 engage in the openings 303 - which are also referred to as holes 2 and also as star holes 2 in the case of a star-shaped configuration of the holes 2 - of the counter plate 1 on the wall element 8, the spring parts 6 are slightly radially outwards from the bolt 22 pushed away, thereby the bolt 22 is held by the resilient parts 6, in particular held by friction. These spring parts 6 are arranged precisely in the area between the outer diameter or outer circle 3 and the inner diameter or inner circle 4 and are delimited by the edges of the star triangles or the bulges 30 .

Due to the fact that the spring parts 6 are arranged in this area 31, the star bolts 22 can find additional support in the round holes 28 of the wall panels 8.

The small resilient parts or spring parts or elastic elements 6 are thicker at their base near the longitudinal plate or body 1 than at their free ends and are slightly tapered or formed in two or more different sections with different thickness. The edges of the resilient parts are chamfered.

On the counter-plate 1 there is one or more round dowels 10 formed on the inside, preferably with a diameter of 8 mm, preferably formed with corrugations, which dowel the counter-plate into the wall 8, ie fasten it. The dowel 7 is slightly chamfered. Likewise, the counter plate could also be screwed to the wall. The counter plates or base bodies are preferably made of a stable, slightly elastic material such as polyamide, but can also be made of other plastic or metal.

For special connections, the longitudinal plate of the connector is provided with a T-formation in the middle at 90° and preferably with three or four bolts, preferably star-shaped bolts 22, preferably with M8 threaded hole 14, resulting in a special U4 connector 15.

For angled connections, the connector is formed with a hinge 224, creating an articulated connector 16, the hinge being formed so that the pivot point is exactly at the outer, vertical edge of the wall panel, so that the wall joint when changing the angle between the walls always remains almost closed. The articulated connection is non-releasably connected to a hinge axis 17, preferably with a screw, but this could also be released with a riveted connection or a welded bolt connection. This allows the articulation to rotate with a predetermined resistance and maintain the set position.

Another variant of the connector is the rigid angle connector 18, here the star bolt 22 is twisted according to the required angle on the longitudinal plate 21 of the connector and the distance between the star bolts is adjusted accordingly. This type of connector is cheaper to manufacture and more stable than the variably articulated angle connector.

Another advantage is that various extensions can be screwed into the threaded hole 14, preferably M8, of the connector. A possible extension are adjustable feet 13. Another extension are attachment bolts 14, through these the normal connectors such as U-connector 11, articulated connector 16, U4-connector 15 become the corresponding connectors for wall attachments 32, walls can be built on top of each other without completely new connector variants become necessary, the existing connectors only have to be expanded.

With the invention it is achieved on the one hand that the connector bodies 200 inserted into the wall panels 8 are held in a stable manner, that is to say they do not fall out when being moved and can nevertheless be easily removed. With the invention, right-angled floor plans can be built with only one type of connector, the U-connector 11, for the straight connections, end connections and corner connections. For special connections, only one other type of connector is required, the U4 connector 15, and for angled connections, no matter what the angle, only one other type of connector is required, the articulated connector 16, in which the angle can be adjusted without tools. Depending on the connection requirements, the bolts 22 of the connector engage in other holes in the counter-plate at the wall corners or only a few types of connector are required. The construction and dismantling of the partition wall system is significantly simplified with very high stability.
