DE19801509A1 - Furniture castor roller for assisted sideways movement - Google Patents

Abstract

The castor roller (4) can move vertically within limits on or in a foot (1) and is pressed automatically onto the ground (7) with its peripheral surface (6) by a spring (5). The foot is hollowed out (2) to accommodate a sleeve (3) with a joined ball at its bottom end to be urged downward by the overlying coil spring. The outer rim of the ball is pressed to the ground thus forcing the standing surface (8) of the foot upwards. The spring is compressed under the weight of a seated user, thus moving the ball up so that the standing surface provides the braking effect at ground level.

Description

The invention relates to a rolling body for easier seitli Chen moving objects, especially sitting or other furniture, due to its weight by means of lint rest on a surface.

To z. B. light an office chair when needed on the floor To be able to move laterally, the foot elements of the Like seating furniture often rolls, which if necessary can be braked.

However, such rolling elements are comparatively expensive and for a u. U. also retrofitting to normal chairs, Armchairs or other seating furniture is not very suitable because Increase seat height and often as visible elements Adversely affect furniture design.

The invention has for its object a generic ß create rolling body that easily in the Foot elements of furniture can be attached and a lightweight teres lateral movement of such furniture allows without that the seat height is changed.

The object is achieved in that the roll body in or on a foot element in an approximately vertical direction is limitedly movable and by the force of an Fe derelementes with its lower peripheral surface automatically against  the surface is pressed.

The rolling body according to the invention can, for. B. from a ball or a role that is gimbal mounted. The Ball or its bearing are in a housing in a vertical direction device limited movement, a spring element, the ball or the roll body in a weight relief of the furniture in a deep presses down.

This housing can now be inserted into a hole in a furniture base be set so that the entire device from the outside is not is more visible.

The spring force, which is preferably set in the rest can, is now to the respective weight of the furniture adjusted that the lower peripheral surface of the ball the furniture lifts something up without additional weight, so that a slight lateral shift is possible. If however, place one or more people on the furniture, the ball becomes slight due to the increased weight shifted upwards or the footprint of the foot downwards pressed against the floor so that it is free against the Movable ball acts as a brake and no longer be a hazard stands that the furniture accidentally slides sideways.

The spring force can of course also be chosen so that an unloaded piece of furniture is non-slip on the surface stands and the ball its load-bearing capacity only through will-emphasized Weight relief of the furniture developed.

The invention is illustrated in the drawing, for example light and is based on the drawing in the following described individually. Show it:

Fig. 1 a rolling body inserted into a furniture base in a position in which the furniture is relieved of weight and

Fig. 2 shows the rolling body of FIG. 1 in a weight-loaded state of the furniture.

The furniture foot 1 shown in the drawing figures has an inner cavity 2 into which a socket 3 is inserted. At the lower end of the socket 3 there is a cardanically mounted ball 4 , the ball 4 or its bearing being pressed down by a spiral spring 5 , which is arranged in the socket above the ball 4 , in the unloaded state into the position shown .

In this position, the lower peripheral surface 6 of the ball 4 presses against the base 7 , so that the footprint 8 of the furniture foot 1 is pressed upwards and a problem-free lateral shifting of the corresponding furniture can take place.

In the position of the ball 4 in FIG. 2, a state is illustrated in which, for example, a user has taken a seat on the seating furniture (not shown). Due to its additional weight, the spring 5 is compressed, so that the ball 4 inside the socket 3 is moved upwards and the base 8 rests on the base 7 with a corresponding braking effect.

Claims (1)

Rolling body for easier lateral movement of objects, in particular seating or other furniture that rest on a sub-ground due to their weight by means of foot elements, characterized in that the rolling body in or on a foot element ( 1 ) limits approximately verti cal direction is movably mounted and by the force of a spring element ( 5 ) with its lower peripheral surface ( 6 ) is automatically pressed against the surface ( 7 ).
