DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a frame with an inserted board, particularly a table top, wherein the frame has a frame receiver corresponding to the shape of the board or table top, and a circumferential frame support edge supporting the board edge and oriented toward the interior of the frame. In this case the frame receives the board or table top and also directly supports it. In the case of a table, the frame is equipped with at least three table legs. However, if the frame is otherwise supported, for example on consoles or the like, or as an intermediate board between two tables, the legs are of course omitted, but in this case the board is also directly supported on the frame.
Frames or tables with inserted boards are already known per se. The board is maintained in the frame because of its inherent weight.
SUMMARY OF THE INVENTION
It is an object of the present invention to maintain the table top in the frame by means in addition to its inherent weight, so that at least it cannot simply be removed out of the frame.
This object is attained in accordance with the present invention in that it is proposed to embody the frame with the inserted board such that the board, particularly the table top, on at least two edges or edge parts, which are located approximately opposite each other, has respectively a spring-elastically pivotable member which projects underneath an interior frame projection or interior frame edge facing the board edge, which can be put into a release position by means of an adjustable operating element supported on the frame. Since this board is maintained in the frame on at least two oppositely located edges or edge parts, it can only be removed out of the frame, if necessary, if previously each blocking member has been brought into a non-effective position. This is true for a round or an oval frame as well as a frame with corners, the latter being required to have three or more corners.
Because the blocking member projects below the associated frame projection or an interior edge of the frame protruding inward, the board can neither be pushed up from below nor be removed in another way, the latter being difficult anyway when the board has been inserted deep enough or completely into the frame. In addition, the weight of the board also plays a decisive role during removal or problem-free removal.
By operating the operating element associated with each blocking member it is possible to cancel the blocking action of the associated blocking member, so that this frame edge is released. However, since at least two blocking members per board are provided, it is necessary to bring all of them into the non-effective position by means of their associated operating elements and to keep them there sufficiently long until the board has been lifted out of the frame at least far enough that the blocking members no longer can assume the blocking position.
An embodiment of the present invention provides for the blocking member to be embodied as a spring-elastic lever with a blocking projection or to support a lever of this type, wherein the projection extends below the frame projection or interior edge of the frame. A separate blocking member spring can be omitted because of the inherent resilience of the blocking member, because of which the structure becomes simpler, less expensive and more sturdy. The size and shape of the blocking projection depends on the local conditions, i.e. particularly the shape and size of the frame projection or the interior edge of the frame. The latter can be created, for example, by undercutting or it can immediately be embodied by providing a profile on it.
A further embodiment of the present invention is distinguished in that the flexible lever of the blocking member has a detent which projects in the same direction as the blocking projection and which engages a locking recess when the blocking member is locked. While the detent prevents the lifting of the board out of the frame, by means of the detent and the recess in the frame a m
