ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a device for positive locking connection of a wall mounting with a support member by hooking, wherein the wall mounting is a hollow cylindrical body with an outer mantle, an inner mantle, and a bottom, and wherein the support member is preferably L-shaped.
Wall mountings are known in the prior art in which, for example, metal strip brackets are mounted on a wall to which support brackets can be coupled. For example, the perforated strip brackets are fastened by plug and screw anchors in a time consuming operation to the wall, and the support brackets are then hooked in or suspended from the holes in the perforated strip bracket. The support brackets receive shelf boards. Not only is the connection by plug and screw anchors, requiring multiple such anchors, time consuming for each one of the perforated strip brackets and thus work intensive, but the connection requires also a certain amount of manageability and dexterity by the user. The conventional wall shelves are sufficient when it is not necessary to load the shelves too much, but already when placing books etc. onto the shelves, there is the risk that the stress over time will cause the perforations of the perforated strip brackets to become fractured because of material fatigue or to rip. At least the suspension location of the support bracket hooks, having a thickness matching substantially that of the wall thickness of the support brackets, become overextended in the holes of the perforated strip bracket so that there is the risk of breakage.
In order to prevent the support members from breaking out of the perforated strip brackets, the support members according to the prior art are fastened by plug and screw anchors to the walls. However, this again requires a lot of time and great dexterity of the user.
Further developments of such support bracket systems as self-locking support bracket systems with square or U-shaped columns with double support brackets do not eliminate the disadvantages with respect to footprint size requirements.
In conventional flat wall strip brackets, the shelf boards are supported on cylindrical support pins which are inserted into matching holes of the perforated strip bracket. The uniform distribution of these holes makes it possible to move the support pins and thus the individual shelf boards, but the wall strip brackets are not suitable for medium weight objects to be stored thereon because of the minimal wall strip bracket thickness. The U-shaped wall strip brackets with supports are more stable than the flat ones and provide a sufficient stability and load carrying capacity, but their application is substantially limited by the large amount of wall surface area needed.
Furthermore, the attachment of conventional perforated brackets results in a limitation of the design possibilities and attachment possibilities of shelf boards because a sufficient amount of wall surface area must be provided for attaching at least two such perforated brackets.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a device which eliminates the aforementioned disadvantages of the prior art. Furthermore, the device should be easily attachable to walls and allow easy coupling or hooking, respectively, unhooking of support members which are to be attachable in a variable manner, while, at the same time, sufficient flexibility, for a customized design and arrangement at the wall should be provided. Furthermore, the device should require less assembly time and should be less labor-intensive while at the same time having a high load carrying capacity. These objects are solved by the inventive device of the independent claim. The dependent claims relate to preferred embodiments of the inventive device.
The invention relates to a device for a positive-locking connection of a wall mounting and a support member by hooking or suspending, whereby the wall mounting is a hollow cylindrical body with an outer mantle, an inner mantle, and a bottom. The wall mounting is characterized in that the bottom has a perforated hole, the length of the perforated hole being shorter than the inner diameter of the inner circle described by the inner mantle within the hollow space of the hollow cylindrical body. The longitudinal axis of the perforated hole intercepts the center point of the circle of the inner circular surface and/or of the outer circular surface, respectively, the cylinder axis of the hollow cylinder. At the upper end of the outer mantle a lip is arranged which extends annularly about the outer mantle. The support member is L-shaped.
The inventive device for a positive-locking connection of the wall mounting and a support member is embodied as a hollow cylindrical body. The hollow cylindrical body is preferably of a circular cylindrical design and, even more preferred, of a hollow cylindrical design. The body has an interior with a cylinder axis, also referred to as hollow cylinder axis. The surface of the bottom facing the interior corresponds to the inner circular surface. The surface of the bottom facing away from the interior is the outer circular surface having a center of a circle. The preferably circular cylindrically designed inner mantle describes or delimits the inner circular surface having a center of a circle. The centers of the circle of the inner and outer circular surfaces advantageously coincide. Also, the outer mantle of the body can describe or delimit the outer circle or circular surface, having a center that can correspond to that one of the inner circle. The inner circular surface at the lower end and the inner circular surface at the upper end of the body may be identical. The outer circular surface at the lower end and the outer circular surface at the upper end of the body may be identical. The straight line connecting the centers of the outer circular surface and of the inner circular surface can determine the cylinder axis or hollow cylinder axis. The bottom has an elongate hole, for example, a slotted hole. The elongate hole is oriented such that the longitudinal axis of the slotted hole intercepts the center of the inner circular surface. The two ends of the slotted hole are spaced from the inner mantle. In a further embodiment the spacing of the two ends of the slotted hole from the inner mantle are identical.
Furthermore, the hollow cylindrical body has a lip at the upper end of the outer mantle, wherein the surface of the lip facing the lower end of the outer mantle is advantageously perpendicularly arranged to the outer mantle. The lip can also be of an annular design extending about the bottom. The bottom and the lip are embodied advantageously as a unitary part. The lip can have an angular, such as quadrangular or hexagonal shape, or be circular, depending on the wishes of the user or the technical requirements. Even more advantageous is the unitary or monolithic design of the wall mounting.
After drilling a hole into a wall, having a diameter which corresponds substantially to the diameter of the outer circle described by the outer mantle, wherein minimal deviations are not impairing the mounting action, the body is inserted into the hole to such an extent that the surface of the lip which faces the lower end of the outer mantle or the body, is arranged at the wall as flush as possible. It is understood that the diameter of the hole in the wall should be matched to the outer circle as closely as possible. However, if there is a minimal difference between the two diameters, a sufficient coupling between the wall and the wall mounting of the inventive device is substantially ensured. Furthermore, when the hole has a slightly smaller diameter in comparison to that of the outer circular surface, a positive-locking connection is ensured in a sufficient manner after insertion of the body by means of slightly hammering or rotating of the outer mantle of the body provided with projections and/or depressions (see below). It may even be further enhanced by a frictional and/or positive-locking connection of the wall
