Description

The invention relates to a fastening device for mounting a component on a grid of square or rectangular grid fields forming, arranged at right angles to each other bars, with a component supporting the holding plate of equal or lesser extent than the grid fields on one side of its radially circumferential contour of a two Having side walls having first groove, with which the holding plate is insertable into a first grid bar of a grid field, and having a two side walls having second groove on the opposite side of the first groove of the radially circumferential contour of the holding plate, which extends parallel to the first groove and with its groove opening of the slot opening of the first groove is directed opposite, wherein the second groove in the first grid bar opposite grid bar of the grid field is used.

In such a fastening device, it is known to introduce an upper horizontal grid bar of a grid array in the horizontally extending first groove of the inclined relative to the grid plate holding plate to the groove bottom, wherein the depth of the first groove is greater than the depth of the second groove and the distance between the groove bottom of the first and the second groove is less than the distance of two horizontal bars of the grid field.

The depth of the first groove is so large that when planting the upper horizontal grid bar at the groove bottom, the holding plate can be pivoted in the plane of the grid field.

By lowering the holding plate, the lower horizontal grid bar passes into the second groove until it rests against the groove base and is held in this position by the gravity of the holding plate.

In this case, the upper horizontal grid bar remains in the first groove.

Then, the components are attached to the support plate, there may be an unintentional lifting the holding plate from the bars.

If the components are hydraulic components and connection couplings, to which hydraulic hoses lead, it can come with a corresponding intensity of pressure surges in the hydraulic hoses and hydraulic components to such vibrations of the holding plate that it pops out of the bars.

The object of the invention is therefore to provide a fastening device of the type mentioned, which is easy to assemble and disassemble with a simple structure, and secured against automatic release from the grid field.

This object is achieved in that the one side wall of the second groove is a movable side wall which is movable between a second groove laterally closing the use position and the second groove laterally releasable mounting position, wherein the distance from the groove bottom of the first groove to the groove bottom of second groove corresponds to the distance between two bars of a grid field or corresponds to the distance of the bars.

A slight play between the mentioned groove bases and the bars is of course present to allow insertion. Preferably, the distance from the groove bottom of the first groove to the groove bottom of the second groove is 0.98 times the distance between two grid bars of a grid array or slightly smaller.

With this design, the two inserted into the grooves bars are at least largely without or with very little play on the Nutgrunden grooves in investment, so that no movement of the mounted plate in the plane of the grid field is possible, leading to a release of the holding plate would lead to the grid field. The movement forces of the holding plate are forwarded directly into the grid.

The mounting position is the position in which the movable side wall for the assembly and disassembly of the holding plate is moved out of the region of the second groove.

For ease of assembly, a first grid bar is inserted into the first groove until it abuts the groove base and then the inclined plate is pivoted about the grid bar located in the first groove into the plane of the grid field. In this case, a second grid bar of the grid field parallel to the first grid bar passes from the side into the second groove, the movable side wall of which is located in a laterally releasing mounting position now being brought into a use position laterally closing the second slot.

Since no gravity of the retaining plate is required to hold the holding plate in the grid field, neither the bars nor the grooves must extend horizontally.

Any other extension is also possible.

In a simple embodiment, the movable side wall can be guided in a direction parallel to the side walls of the second groove guide recess of the holding plate between the use position and the mounting position.

If the movable side wall is acted upon by a spring force in the use position, then after a movement of the second side wall against the spring force for mounting the holding plate takes place an automatic movement of the second side wall in the use position and a secure hold in the use position.

In order to prevent movement of the second side wall beyond the use position and a release of the second side wall of the holding plate, the movement of the movable side plate from the mounting position to the use position in the use position may be limited by a stop.

In a simple embodiment, the movable side wall has a projecting transversely to the side wall approach, which projects into a Begrenzungsausnehmung the support plate and between the use position defining a first end and a mounting position defining or limiting second end of the Begrenzungsausnehmung is movable.

If in this case the limiting recess is designed to be continuous in a side surface of the holding plate and the projection protrudes from the holding plate on this side surface, a simple displacement of the second side wall from the use position into the assembly position is possible by application of force to the end protruding from the holding plate.

In a simple way, the limiting recess is a slot extending in the direction of movement of the movable wall, the ends of which are the use position and the limiting position defining or limiting the mounting position.

For a simple latching of a grid bar on the movable wall in the second groove, it is when the movable side wall is formed at its groove opening facing the end side of the second groove remote side to the second groove near the side ramp-like rising.

The movable side wall may have a shorter length transverse to its direction of movement than the fixed side wall of the second groove.

The movable side wall may even be formed by a movable in its longitudinal direction bolt, which is then only in line contact with the inserted into the second groove grid bar. The guide recess of the bolt is then a guide bore.

If the guide bore is a blind bore, then a compression spring can be supported on its bottom, which acts on the movable side wall in its use position.

In the holding plate can be formed on one or both side surfaces outwardly opening channels at the outwardly leading mouths hydraulic components or pneumatic components and couplings can be arranged.

The inventive attachment of the retaining plate to the grid field and pressure surges in the supply lines to the connection couplings and in the pneumatic or hydraulic components and unintentional force acting on the support plate can not lead to an automatic release of the holding plate from the bars.

An embodiment of the invention is illustrated in the drawing and will be described in more detail below. Show it
