DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a stand or separation, especially a book end to be used on book shelves, shelves, desks and the like furniture having one or more horizontal plate elements, for example, shelves and to a construction for gripping the shelf so as to enable the respective shelves to be fixed thereon by sliding a support element in relation to a resilient element.
BACKGROUND OF THE INVENTION
In, for example, Swedish Patent 109,121 a book-end is proposed wherein the fixation to the shelf takes place by sliding two elements relatively to each other. A support part and the part engaging the underside of the shelf are made as a unit, with a wedge action arising by the lower part of the support being provided with a wedge track which is inclined towards the shelf. The book-end is comparatively complicated, as a track has to be made both in the fixed and in the sliding part. Moreover the adaption of the book-end to various shelf thicknesses is limited due to the wedge-track rendering no alternative variations.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a stand or separation of a modern design, with a wide range of adaption to different thicknesses of shelves, and, at the same time, having a simple construction and being especially functional, as without screws and small springs it can be fastened on a shelf.
This is achieved by a stand or separation according to the invention, characterized in that the support element rests against the shelf with a support area and can be locked thereto by the resilient element, which has a branch parallel to the support area of the support element, which branch is resiliently connected to another branch, which is inclined in relation to the first branch, such that the together from a wedge, and is slidably connected to the support element. By displacement of the support element the distance to the resilient element, which engages the opposite side of the shelf, can be changed, causing a clamping force on the shelf between the supporting element and the resilient element. This results in an area pressure between one side of the shelf and the support element and an area pressure between the resilient element and the opposite side of the shelf.
The attachment to various shelves of different thicknesses is achieved by more or less displacing the support element on the resilient element. The wedge angle of the resilient element and the rigidity is chosen such that the support element is self locking by means of friction, which contributes to the simplicity of the book-end.
By placing holes for the resilient element in the support element at different distances, a greater adaptability for different thickness of shelves is achieved by turning the support element.
In a further embodiment of the book-end according to the invention the support element can be made with more sets of holes or tracks (depending on whether the support element is solid) and thereby having wide-range adaptability.
Preferably the lower branch of the resilient element is inclined slightly upwardly towards the engaging area of the support element, such that there, by tightening of the stand or separation around a shelf, is caused a pre-tension in the lower branch, which branch initially engages the shelf with its outer end a distance along the shelf, and, thereafter, in its entirety is pulled upwardly against the shelf.
