BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention concerns an elastic (i.e. resilient) foot for an apparatus (component) as disclosed in U.S. Pat. No. 4,767,105.
When feet of the type disclosed in that parent application are employed and several components are stacked on top of a compact-disk player, the unsymmetrical load on the feet of the player may make the stack lean. This situation may occur when the line connections into several components stacked into a tower are all on one side. Feet that are loaded in this way are compressed more than the less loaded feet, and the tower will accordingly tend to lean. The unfortunate result is not only unattractive, but the instability of the upper components in particular can lead to manfunction of the controls.
SUMMARY OF THE INVENTION
The object of the present invention is accordingly to improve stability when the four feet of a compact-disk player are unsymmetrically, or even symmetrically, loaded while maintaining the return motion constant.
Since it is impossible to predict how the owner of a compactdisk player will combine it with other components, it is important to find a flexible solution to the problem.
Further developments and details of the invention will be evident from the subsidiary claims and from the description.
Using reinforcing rings results in the requisite improvement in stability and, since they can be added on or removed later by either the manufacturer or the user, any lack of symmetry or leaning resulting therefrom can easily be compensated for.
One embodiment of the invention will now be specified with reference to the drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view from below and from one side and an exploded view of the rubber part and a reinforcing ring and
FIG. 2 is a side view sectioned at two levels of the assembled rubber part and reinforcing ring.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The rubber part has as will be evident from FIG. 1 three rectangular, radially oriented, and equally distributed openings 5, 6, and 7 that accommodate projections 10 on a reinforcing ring 8. Noses 11 on projections 10 engage the resilient material that rubber part 1 is made out of on the other side of openings 5, 6, and 7 and ensure that reinforcing ring 8 will remain in place once it has been forced on, while still allowing it to be removed as necessary. A central convexity 12 on rubber part 1 extends through a central opening 9. When the compact-disk player is employed by itself without load, the situation will be evident from FIG. 2. When it is subjected to load, rubber part 1 will compress (in an unillustrated way) and the flat lower surface of reinforcing ring 8 will provide additional support.
When there is no additional stress, the situation will be as described in the U.S. Pat. No. 4,767,105. When the load is increased, the parameters provided therein with respect to return motion will remain more or less constant, and the reinforcing rings will improve stability as a result of their more extensive supporting surfaces.
In summary, the present invention is concerned with a resilient foot for supporting consumer electronics components, such as compact disk players, in which a reinforcing ring is placed against a rubber member from below. The rubber member has a central convex portion extending through a central opening of the reinforcing ring. The reinforcing ring has a lower surface in contact with a supporting surface at an outer edge of that lower surface. The reinforcing ring, furthermore, has projections on one side that are substantially parallel to the central axis of the ring. The rubber member has openings which correspond in shape to the projections on the ring. These projections extend into the openings in the rubber member, and the projections are integrally formed with the reinforcing ring. The rubber member, moreover, has a surface which contact with the convex portion of the rubber member is flattened under load of the electronic component being supported, the plane passing through the top surfaces
