DESCRIPTION:
BRIEF SUMMARY
The invention relates to furniture mounts consisting of a housing which can be affixed to furniture and a horizontally and vertically adjustable carrying component movably supported in the housing. Horizontal and vertical adjustment each take place by means of a respective screw which is in threaded engagement with the carrying component.
Many designs for such mounts are known. The purpose of the horizontal and vertical adjustment is to be able to compensate for unevennesses at the building wall and/or positional inaccuracies of the carrying elements on the wall side during mounting of the furniture.
However, precisely during the horizontal adjustment, it has been found that the horizontal adjusting screw is frequently rotated out too far as a result of unawareness so that the threaded connection between carrying component and horizontal adjusting screw is broken. For all practical purposes, the adjustability in the horizontal direction is then lost because, due to the dropping of the cabinet under its weight, and due to the lack of a view into the housing of the mount, the horizontal adjusting screw cannot, or can only with great difficulty, again be screwed into the carrying component.
To prevent this unintentional separation of horizontal adjusting screw and carrying component, it has been proposed to attach to the end of the horizontal adjusting screw a safety disc or, by subsequent deformation of the end of the screw, to provide a thickening which prevents the screw from rotating out of the internal thread of the carrying component. Both proposals result in additional manufacturing costs and significantly increase the difficulty of assembling the individual parts, i.e., the assembly costs increase also.
The object of the present invention is to provide an economical solution which, with a minimum expenditure for manufacturing and assembly, reliably and inexpensively prevents a complete separation of carrying component and horizontal screw--while excluding all of the drawbacks associated therewith--.
This object is achieved in that the end of the horizontal adjusting screw carries an unthreaded portion of smaller diameter and that the thread-carrying portion in no longer in threaded engagement with the internal thread of the carrying component when the carrying component is in a terminal position inside the housing.
The terminal position of the carrying component in the housing is established in a simple manner by projections/ abutments affixed to the housing or the carrying component, or by abutment of the vertical adjusting screw against the narrow end of the keyhole-shaped, slotted hole.
The diameter of the unthreaded portion is favorably equal to or smaller than the root diameter of the thread. It can be of advantage to select the ratio of the lengths of the threaded portion and the unthreaded portion so that the threaded portion is approximately 2/3 and the unthreaded portion 1/3.
A preferred exemplary embodiment is illustrated in the drawings. There is shown:
FIG. 1 a sectioned housing with partially sectioned carrying component in a terminal position of the carrying component,
FIG. 2 the bottom zone of the hosing with the keyhole-shaped, slotted hole in a sectional view along the line II--II of FIG. 1.
The mount consists of the housing 1 which, in a known manner not illustrated in greater detail, can be secured to the furniture by means of pegs 2 formed on the housing 1 or by means of screws.
The movably supported carrying component 3, which has essentially an approximately U-shaped outline, is located in the interior of the housing 1. The ends 4 of the carrying component 3, which project out of the housing 1, are hook-shaped for mounting on non-illustrated mounting elements at the building side.
At its other end 5 opposite the hooks 4, the carrying component is provided with an internal thread 6 which is engaged by the thread 13 of the horizontal adjusting screw 12. It being understood that relative orientation adjectives such as "horizontal", "vertical", etc. are utilized herein to simplify th
