Description

The present invention relates to a device for cross-connecting two struts, in particular struts of a support system for spring elements of a mattress or under mattress, according to the preamble of claim 1.

Such a support system for spring elements of a mattress or under mattress is from the EP 2 283 748 A1 known. In this carrier system can be connected to each other by means of a connecting element two struts cross each other. However, it is necessary that one of the struts is inserted through apertures provided on the connecting element, which makes the process of cross-connecting the two struts complex and complicated.

Further prior art is out US 2 248 023 A known.

The invention has for its object to provide a device by means of the two struts with little effort can be connected together in a cross.

This object is achieved by a device for cross-connecting two struts, in particular struts of a support system for spring elements of a mattress or under mattress, with the features of claim 1. Preferred embodiments and further developments of the invention are specified in the dependent claims.

The device according to the invention for cross-connecting two struts, in particular struts of a support system for spring elements of a mattress or under mattress comprises, in particular plate-like formed, base member, wherein on one side of the base member, a first receptacle for a first strut is formed, in which the first strut from this side can be inserted, and wherein on one side of the base member, a second receptacle is formed, in which a second strut is insertable from this side so that it extends crosswise to the first strut inserted in the first receptacle, and wherein locking means are provided, through which the two struts are fixable in the two receptacles.

The two struts can be connected easily in a cross over each other, since each strut can be easily inserted into the respective receptacle, so that a complex passing or Hindurchfeln through openings, as in the connecting element of EP 2 283 748 A1 is required, not applicable. Using a plurality of devices according to the invention and a plurality of struts, it is thus possible to assemble a carrier system, for example for spring elements of a mattress or under mattress, with latticed struts in a short time and with little effort.

According to the invention, the two receptacles are formed on sides of the base element facing away from one another. This has the advantage that the two arranged in the respective receptacles struts are separated by the part of the base member which lies between the two sides. The struts are thus not directly above each other. In addition, the recordings can also be provided for fixing further elements, such as spring elements, so that they can also be arranged on both sides of the base element because of the two-sided arrangement of the recordings.

Preferably, the two recordings are mirror-symmetrical to a plane lying between the sides facing away from each other center plane and relative to a plane perpendicular to the median plane axis rotated by 90 ° to each other. The recordings are thus formed the same on both sides of the base member and rotated by 90 ° to each other, so that the inserted into the two shots struts cross each other. Due to the symmetrical construction of the base element, it is irrelevant in which of the two receptacles the first or the second strut is inserted. The base element thus provides no orientation that must be observed when connecting the two struts, which greatly simplifies the assembly.

The locking means may be releasably connectable to the base member. Thereby, the locking means and the base member can be made independently and replaced independently if necessary.

It when the locking means to form a clamping or locking connection to the base member can be fixed, since such a clamping or locking connection manufacturing technology is particularly advantageous particularly easy to be realized. In addition, this makes it possible to safely determine the respective strut in the respective recording.

It is particularly advantageous if the struts between the base element and the locking means can be clamped to form the clamping or latching connection. This can be prevented in particular that the struts can slip in their longitudinal direction in the recordings.

The locking means may be formed by at least one locking piece. This can be designed as a separate part.

Preferably, the receptacles each have two essays whose spacing corresponds at least approximately to the width of a strut, wherein the locking piece can be placed in the manner of a bridge on the essays of at least one of the two recordings. In this way, the recordings can be realized structurally simple and arranged in the respective receptacle strut can be set in a secure manner by means of the locking piece on the recording.

Particularly preferably, the locking piece can be defined by means of a rotational movement of the essays, so that the locking piece can be set, for example, to form a screw on the base.

In a preferred embodiment of the invention, the locking piece on the receptacle by means of a formed between the essays and the locking piece bayonet lock can be fixed. The bayonet lock can be realized particularly easily manufacturing technology. It is also advantageous that the bayonet lock between The locking piece and the recording can be closed by hand and opened again. A tool is thus not needed.

On the essays projections and on the locking piece may be formed complementarily formed undercuts or vice versa, wherein the undercuts together with the projections form the bayonet closure. In this way, the bayonet lock can be realized structurally simple.

According to a further preferred embodiment of the invention, means for connecting the device are provided with at least one spring element. It is thus possible to arrange at least one spring element on the device in order, for example, to support a mattress or to form a lower mattress.

Preferably, the means are provided on the locking piece, so that the spring element can be attached to the locking piece and fixed together with the locking piece on the base element. In this case, the spring element can be easily replaced.

In particular, at least one spring element is arranged on the locking piece. As a result, the assembly is further simplified, since the spring element can be fixed together with the locking piece on the base element.

From the production forth, it is advantageous if the locking piece and the spring element are integrally formed with each other. An assembly of the corresponding parts is thereby eliminated.

Particularly preferably, the locking piece forms a base of the spring element, on which a spring body is formed, which extends between the base and a cover plate of the spring element. As a result, the production can be further simplified. In addition, the manufacturing cost is reduced because the locking piece forms the basis for the spring element and thus can account for a separate base.

In a preferred embodiment of the invention, the cover plate is formed as a separate part. As a result, the cover plate can be easily replaced if necessary.

At least one spring element can be attached or attachable on one side and on the side of the base element facing away therefrom. As a result, a device can be provided with spring elements arranged on both sides in order, for example, to serve as a spring core for a mattress.

In particular, if not according to the invention, both receptacles are arranged on the same side of the base member, the spring element provided on this side can be arranged on the locking means, by means of which the struts are fixed. The spring element, which is provided on the other side of the base member on which there is no receptacle, may, however, be directly connected to the base member or connectable.

In a base element, in which according to the invention the two receptacles are provided on sides facing away from one another, it is advantageous if the spring elements are respectively arranged on the locking means which are fixed to the receptacles. The spring elements then do not have to be arranged separately on the base element. In a further preferred embodiment of the invention, the base element has a, in particular in the middle and perpendicular to the one side extending through opening. This can save material and reduce the weight of the device.

The invention also relates to a support system for spring elements of a mattress or under mattress with lattice-like arranged struts, wherein the struts are connected to each other at their crossing points by a respective device according to the invention. In this case, spring elements may be arranged on one side of the device to serve as a bottom mattress, or on both sides as a spring core of a mattress.

By using struts which span substantially the entire width or the entire length of the mattress or under mattress, the total number of parts for constructing such a grid-like support system can be kept low. In addition, the production cost of the support system are relatively low, since the struts can be made endless, for example, as extruded profiles. Also, this is a stepless width and length adjustment possible. In addition, a continuous variation of the mesh size of the grid of the assembled carrier system is easily possible.
