BEDSIDE TABLE BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to swivel top tables of the type having a rotatably mounted upper swivel section particularly adaptable for use in hospitals.

2. Description of the Prior Art Bedside tables of the prior art generally provide a pivotally mounted door in the front section and the rear section so as to provide access from either side. This convenience was primarily intended for bedridden individuals to provide ready access to the inner portion of the lower or cabinet section of the table with minimum effort. A drawer was provided generally in the upper section of the table with a provision for front mounting or rear mounting as required by the individual user. A part of the wall section of the bedside table in the rear portion was removable to facilitate inserting the drawer therein. Thus the drawer could be mounted in the front or the rear of the cabinet.

British Pat. No. 634,749 relates to a bedside cabinet which includes a swivelled upper part which can be rotated to provide access to the drawer from several directions. However no means are provided for locking the roatable section in position once a desired position is selected. Thus a slight force exerted against the upper section will result in rotation of the section away from the desired position thereby creating an unnecesssary inconvenience for bedridden patients who may be unable to rotate the upper portion.

It is therefore an object of this invention to create a bedside table of the type described but having a drawer section which may be used from two or more sides without the necessity to perform any conversions such as rotating the entire table for the convenience of a particular user.

Another object of the invention is to provide a bedside table of the type described having a swivelling upper part which is capable of swivelling into any desired position and locked in that position. Thus a drawer of the bedside table may be used in such a way that it does not swivel further with the upper part if a slight force is exerted against it.

SUMMARY OF THE INVENTION To attain these objects, the invention provides that the upper part which houses the drawer is swivellingly connected to rotate about a vertical axis relative to the lower part, with means for locking the upper part in several predetermined positions. By swivelling the upper part into any desired position the drawer of the bedside table may be used from the one of several sides. The swivelling of the upper part can be done easily by a person in bed and does not provide any difficulties, while a detent means provides for locking the upper part in a selected position.

The invention further relates to the provision of a supporting plate in the lower section at its upper side on which the upper section rests with an appropriate supporting plate by means of a bolt connected thereto. The bolt penetrates the lower support plate.

The object of the invention is solved by the provision of an upper supporting plate with recesses in a circular arrangement for two or more stop balls carried in holes of a lower supporting plate, against which springs are resting from below. By this arrangement of the balls an engaging reception thereof is made possible in several swivelled positions on the one hand, while on the other hand a smooth gliding is ensured'on the lower part while rotating the upper part. The stop balls may be arranged in such a way in this connection that the exact adjustment of the upper part on the lower part is possible if all edges are made to be aligned. The invention also relates to the provision of a bolt member with an adjusting nut supporting itself by way of a spring at the lower end of a guide member which surrounds the bolt. The above-mentioned spring at the end of the guide member provides additional support and the bias of the springs against the stop balls may be selected depending on the particular use intended.

Finally the invention relates to the provision of eight stop recesses in circular arrangement in the upper supporting plate so that the upper part together with drawer may be swivelled and locked at 45 intervals.

Broading stated, a swivel top table is provided having a rotatably mounted upper swivel section which is capable of being locked by a detent means at selected rotational positions. A lower stationary section is provided with at least one door member pivotally mounted thereon to provide access to the inner portion of the lower section. An upper section preferably having a drawer slidably mounted therein, is provided with a substantially planar upper table surface. The upper section is pivotally mounted on the lower section in a manner which permits rotatable swivel movement of the upper section relative to the lower section. Detent means are provided to lock the upper section in selected positions relative to the lower section such that the upper section may be conveniently rotated to any number of positions and locked in the selected position. The preferred table of the present invention is particularly suitable for use in hospitals and thus includes two L-shaped door members which provide substanially complete access to the inner portion of the lower section of the table when opened. Such door members cover portions of an adjacent wall when in a fully opened position. Rotational swivelling support of the upper section is provided by an upper supporting plate which is adapted to rotatably swivel about a vertical axis on a lower supporting plate connected to the lower section of the table by a bolt member. A plurality of stop balls or ball bearing members are positioned in openings in the lower supporting plate while spring members resiliently bias the ball members upwardly in engaging relation with the lower surface portion of the upper support plate. The upper support plate has correspondingly arranged recesses which engageably receive the balls and lock the upper section in position when it is rotated to specified positions. Thus the arrangement as well as the number of balls determines the rotational increments which the upper section may be rotated between locked positions. In the preferred embodiment, eight stop balls are equally spaced to form a circular arrangement while a corresponding arrangement of eight equally spaced recesses are provided on the lower or under surface of the upper support plate. Thus, with such an arrangement, the upper section of the table may be rotated freely while providing locking positions every 45 of rotational movement of the upper section.

BRIEF DESCRIPTION OF THE DRAWINGS Preferred embodiments of the invention are described hereinbelow with reference to the drawings wherein:

FIG. 1 is a perspective view of the bedside table according to the invention with one door shown partially open;

FIG. 2 is an appropriate representation of the bedside table with the upper swivel section shown partially rotated;

FIG. 3 is a side elevation of the upper section of the bedside table with sidewall portions broken away;

FIG. 4 is a top view of the inner portion of the rotatable upper section taken along section 4-4 of FIG. 3;

FIG. 5 is a detailed view of the locking feature of the doors of the bedside table;

FIG. 6 is a vertical sectional view of the connection between the upper and lower sections of the bedside table taken along sections 66 of FIG.- 4; and

FIG. 7 is a one-half portion of a top view of the bedside table with the top table portion removed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS From the drawings it may be seen that the bedside table according to the invention includes a lower section with feet and two L-shaped doors, 2, 3 and a storage area therein, preferably having a horizontally supported storage shelf as shown in FIG. 1 An upper section 4, houses a slidably mounted drawer 5. The upper section 4 may be swivelled to such an extent that the drawer may be used from any desired direction as is shown in FIG. 2. For this purpose the upper section 4 is swivellingly connected with the lower part 1 of the bedside table by means of a bolt 6. The bolt is also connected to a supporting plate 7 of which the upper part is connected, such as by welding with frame 8 of the upper part. The lower section 1 is provided at its upper frame part 9 with an appropriate supporting plate 10, which is provided with centre bore 11 and a bushing 12. The bushing 12 is inserted in the plate 11 and serves to guide and support bolt 6. At the free end of bolt 6 there is provided a nut 13. At its free end the bolt supports an intermediate spring 14 at the lower end of bushing 12. The bolt is secured against spring 14. Between supporting plate 7 and plate there may be arranged several balls such as 15 to 19 as shown (three balls not shown in FIG. 7) in holes in plate 10 which are held from below and biased upwardly by

springs

20, 21. Thus through the action of

springs

20, 21 the balls 15 to 19 are engageably received in

recesses

22, 23 in previously determined swivelling positions of the upper section to provide a detent or lock. Such balls may be of any type which is capable of supporting the bearing loads provided by the upper section. Thus for the purpose of this description, these balls may be referred to as ball bearing members.

Both

doors

2, 3 are locked with double hooks 24 in the manner shown in FIG. 5 such that at any time only one door may be opened if desired.

As indicated in FIG. 7, there are provided eight balls equally spaced and circularly arranged such that adjacent balls are spaced by approximately a 45 are on the 6 circle. The appropriate correspondingly arranged recesses 22, 23 in the lower surface portion of the upper supporting plate 7, make it possible to swivel and lock the upper section 4 relative to the stationary lower section 1 every 45 of rotation such that a position such as the position of the upper section 4 may be reached as represented in FIG. 2.

The numbers and arrangements of the balls and recesses can be varied to determine the desirable stop angles provided in the pivotal incremental movements of the upper section of the table. The convenience to bedridden patients unable to rotate the entire table to facilitate the use of the drawer may be clearly seen from the versatility of the table as described.
