BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a device for holding a drawer in an article of furniture.
Devices of this type serve, on the one hand, to cushion a drawer to be inserted during the last insertion stage and, on the other hand, to hold a drawer to be inserted in a terminal position such that it can only be withdrawn by overcoming a resilient force, albeit small.
To this end, it is known to mount a fork component on the side of the drawer while the pin which the fork component is affixed to the side wall of a furniture article.
It is here necessary to the spacing between the corresponding side of the drawer and the side wall of the furniture article relatively precisely. Otherwise, there will be malfunctions, i.e., the pin will be too short or too long so that it is either unable to engage the fork component altogether or projects in too far with the result that operation is not possible.
In this connection, a given dependence of certain guide rails is also to be considered as disadvantageous. The corresponding components of these guide rails are affixed to the drawer, on the one hand, and to the furniture article, on the other hand, and the guide rails can only be selected taking into account the pin length or the pin length must be adjusted to their dimensional characteristics.
In any event, a construction of the device which can be employed without restriction for all usable guide rails is not possible.
In practice, the situation can arise that the fork component is unintentionally pivoted to a holding position before the drawer is pushed into a holding position, that is, before engagement of the pin in the fork opening, so that the pin cannot engage the fork opening when the drawer is closed.
SUMMARY OF THE INVENTION
It is an object of the present invention to design a device of this type in such a manner that, using means of the greatest structural simplicity, the utility of the device is improved, a reliable return of the fork component is assured and the overall life of the device is increased.
This object is achieved by a holding device having a return mechanism provided with a guide channel which is open at two sides and extends approximately parallel to the fork opening. One opening of the guide channel is adjacent the fork opening while the other opening is closable by a resilient locking bar which opens towards the guide channel.
For one, the invention allows the device to be arranged on the underside with the pin secured to the drawer while the fork component with the connected return mechanism can, for example, be secured to a support rail which is fastened to the furniture article.
Accordingly, no requirements exist as regards tolerances and guide rail type so that the use of the device has no influence on the mounting and employment of guide rails.
A particularly advantageous embodiment of the invention provides for the return mechanism and the fork component to be constructed as plastic part and to lie in the interior of a housing having a slot which is open at one side. The common pivot pin of the fork component and the return mechanism lies in the slot.
This structural embodiment makes possible a particularly simple manufacture of the overall device since especially the assembly thereof, that is, the mounting of the fork component and the return mechanism in the slot, requires very little expenditure.
