ABSTRACT:
TECHNICAL FIELD
The present invention relates to a bracket for engagement with or securing on an object of substantially rigid or inflexible material of a predetermined thickness.
Background Art
In the surface treatment of objects, such as sheet metal parts, aluminum profiles etc., these are suspended in hooks which hang in a row on a conveyor. When the objects which are to be surface treated are immersed in a bath, it happens on many occasions that the objects begin to float, since air may have been entrapped in pockets, cavities etc. At worst, this may result in the object coming loose from the hooks. For these parts not to come loose from the suspension members of the conveyor, it is important that they are held steadily clamped. Further, it is occasionally of interest that the abutment of the bracket against the object being surface treated is at a minimum. Moreover, the mounting of the brackets must be simple and not require any special tools.
Problem Structure
The present invention has for its object to realize a bracket which has a fast grip with a limited abutment against the gripped object and which may be mounted in place and removed by means of a single operation. Further objects of the present invention are to realize electric contact with the object and also to give low production costs and simple operation.
Solution
The objects forming the basis of the present invention will be attained if the bracket according to the present invention is characterized by an approximately V- or U-shaped body portion produced from resiliently yieldable material and having two shanks, a recess in each shank open towards one of its edges, the recesses having defining edges, and there being provided, in association with each recess, an abutment means opposite the defining edge, and the arrangement being such that, on placing of the defining edges in line with one another and with the eye of the observer, the shanks have, by bending away from or towards one another, a first position where a look-through region between the defining edges and the abutment means has a thickness which is greater than the predetermined thickness, and the shanks, after return springing, have a second position where the thickness of the look-through region is less than the predetermined thickness.
Further advantages will be attained according to the present invention if the bracket according to the invention is also given one or more of the characterizing features as set forth in the appended claims.
