The receiving part (3) is adapted to be attached to a mount (9) comprises a carrier (9) with a horizontal bearing surface (10) for the receiving part (3). A depression (11) is located in the carrier (9) and adapted to receive the rim end portion (4b) of the receiving part (3) to provide a mechanically locking engagement. The mount also includes a projection (12) which is arranged at a distance from the depression (11) corresponding to the rim height of the receiving part (3) and which extends at least partially over the upper surface (6) of the rim (4) when the receiving part (3) is placed on the carrier (9).
What is claimed is: 1. A table assembly of the type for receiving dental tools, such as a set of instruments and the like, said table assembly comprising a holding arm, a mount attached to said holding arm and a receiving part which is releasably engaged with said mount, wherein:said receiving part has a tool receiving bottom surface and a rim end portion having a predetermined height extending in a generally perpendicular direction relative to said bottom surface and encircling at least a portion of the perimeter of said bottom surface, said rim end portion having a lower rim edge extending downward relative to said bottom surface, and an upper rim edge; said mount comprises a horizontally extending support part which in a longitudinal dimension of said support part is stationary with respect to said holding arm, a projection which is stationary with respect to said support part, and a carrying part mounted on said support part in a manner which allows movement in a longitudinal direction of said carrying part relative to said support part, said support part and said carrying part having guide elements coupled thereto for effecting said longitudinal movement of said carrying part relative to said support part; said carrying part includes a depression therein dimensioned to engage with said downwardly extending lower rim edge of said receiving part; and said projection of said mount is vertically spaced at a distance from said depression of said carrying part corresponding substantially to said height of said rim end portion of said receiving part, said projection and said depression being adapted to engage said upper and lower rim edges of said receiving part, repectively, when the lower rim edge of said receiving part is positioned in said depression and said carrying part and receiving part are moved longitudinally in a first direction relative to said support part until said projection of said mount engages said upper rim edge of said receiving part. 2. The table assembly according to claim 1, wherein:said upper rim edge of said receiving part extends upwardly from said bottom surface and has a bevelled shape angled so as to facilitate engagement of said upper rim edge of said receiving part with the projection of said mount when said receiving part and carrying part are moved longitudinally in said first direction. 3. The table assembly according to claim 1, wherein said rim end portion extends completely around the perimeter of said bottom surface of said receiving part and is of constant cross-section.
4. A table assembly according to claim 1, wherein:said guide elements comprise a guide pin attached to said carrying part and a slot formed in said support part which receives said guide pin for defining the direction of said longitudinal movement of said carrying part relative to said support part. 5. A table assembly according to claim 4, further including:spring means coupled with said carrying part which undergoes compression when said carrying part is moved in said first direction, thereby urging said carrying part to move in a second direction which is opposite said first direction; and said support part includes stop means which contacts said carrying part for preventing lateral movement of said carrying part in said second direction when said projection of said mount is engaged with said upper rim edge of said receiving part. 6. A table assembly according to claim 4, further including:spring means coupled with said guide pin for urging said carrying part against said support part. 7. A table assembly according to claim 6, further including:first and second stop means connected to both of said support part and said carrying part which, due to the urging of said spring means, act to limit said longitudinal movement of said carrying part relative to said support part in said second direction, said first stop means limiting said movement when said rim of said receiving part is engaged with said projection of said mount and said second stop means limiting said movement when said rim of said receiving part is not engaged with said projection of said mount. 8. A table assembly according to claim 1, wherein said carrying part comprises:at least one inlay part forming a bearing surface for said receiving part; and selectively adjustable spacing means coupled between said carrying part and said inlay part which in a first adjustment causes said bearing surface of said at least one inlay part to be flush with a supporting surface of said carrying part and in a second adjustment causes said bearing surface of said at least one inlay part to be slightly elevated from said supporting surface of said carrying part. 9. A table assembly according to claim 8, wherein:said selectively adjustable spacing means comprises a second inlay part and a spacer which abuts therewith, said first and second adjustments of said selectively adjustable spacing means corresponding to respective predetermined rotational orientations between said spacer and at least one of said first mentioned and said second inlay parts. 10. A table assembly according to claim 1, further including:an eccentric lever means rotatably secured to said support part for selectively urging said carrying part to move in said first direction, due to rotation of said lever means, by an amount such that when said receiving part is positioned on said carrying part said rim end portion of said receiving part is locked in a space bounded by said projection on one hand and said depression on the other hand. 11. A table assembly according to claim 1, wherein:said projection and support part are integrally formed in said holding arm. 12. A table assembly according to claim 1, wherein:the size of said receiving part is such that commercial trays of a size range from 285�185 mm to 345�245 mm may be deposited thereon. Description
Available on the market are two types of trays whose dimensions are standardized, but which differ in size i.e. 285�185 mm and 345�245 mm. To make it possible for the cutomer to use either one of the trays, the equipment manufactuer must offer mounts for both tray sizes. This, however, means more stock-keeping. If the customer later changes the tray mount, retrofitting costs are involved.
In FIG. 2, the bearing surface 10 is formed by two inlay parts 16a, 16b which are arranged one above the other, embedded in a corresponding recess in the carrying part 9, and resting against abutting surfaces 9a of the carrying part 9. The inlay part 16b is provided with spacers 16c and can be inserted turned around 180�. In the inserted position shown, a bearing surface raised somewhat in relation to the rest of the surface of the carrying part 9 is formed, and in the other inserted position, in which the spacers 16c are inactive, a bearing surface flush with the rest of the surface. By this selective position, receiving parts differently formed with respect to their edge configurations can be taken into account. Advantageously, the selected position can be marked on the inlay part.
