DESCRIPTION:
BRIEF SUMMARY
The invention relates to a closed decoration frame composed of sectional pieces which are connected to one another and are provided with a hollow chamber and which, in use, form visibly from outside an end face and a continuous outer wall and invisibly a back and an inner wall, the end face projecting beyond the inner wall toward the inside of the frame and forming a bearing edge for sheet-like contents of the decoration frame.
Decoration frames of this type are primarily used as picture frames, but also serve to hold mirrors or the like. Conventionally, the sectional pieces for rectangular frames are mitered in the corner region and connected to one another there, for example by gluing. This results in strictly rectangular frames which only have a pleasing appearance when the miter cut has been made extremely carefully. It is therefore not possible to vary the design of the frames in the corner region.
Object of the invention therefore, is to provide a closed decoration frame of the type mentioned in the introduction, in which the shape in the corner regions of the frame can be varied.
According to the invention, this object is achieved in that the sectional pieces are each connected by means of a corner part, in that essentially continues the outer walls and the end faces of the sectional pieces in the corner region and by means of a lug projects into the respective hollow chamber in each of the two sectional pieces and is connected to these there.
In the frame according to the invention, the sectional pieces do not butt directly against one another, but are connected to one another by the corner parts. Where a rectangular frame is concerned, the corner parts have two lugs which are at right angles to one another and which project into the hollow chambers of the sectional parts and are connected to the sectional parts there, for example by gluing or by deformation of the sectional parts. The invention makes it possible to design the frame with normal corners, but also to provide corners with rounded contours.
In a preferred embodiment, the outer edge of the end face of the corner parts is therefore rounded, and preferably the inner edge of the end faces of the corner parts is also rounded. This makes it possible, for the first time, to design a closed decoration frame in a stable manner so as to provide rounded corners which in a simple way connect the sectional parts to one another.
When the corners are also rounded on the inner edge, it is advantageous if the corner parts are designed without an inner wall continuing the inner walls of the sectional pieces and form a receiving space which is free in the extension of the inner walls of the two sectional parts up to the point of intersection of this extension. Although the inner edge of the end face is rounded, pictures, mirrors or the like with rectangular edges can be placed in this frame, since the corner parts have a corresponding receiving space. The decoration frame with rounded corners therefore requires no machining of the generally rectangular pictures, mirrors or the like, which machining may be very costly.
The corner parts according to the invention make it possible to use sectional pieces which are cut off at right angles and which consequently do not have to be miter-cut in a relatively expensive way.
In an especially simple embodiment, the sectional pieces are connected to the lugs of the corner parts by deforming the hollow chambers on the inner wall into the inserted lugs. After the corner parts have been inserted into the hollow chambers, therefore, the invisible inner wall of the hollow chambers is merely deformed at particular points, the deformation consequently pressing into the lug of the corner part and making a firm connection. For this purpose, the corner parts are preferably made of plastic. Alternatively, screws can be screwed into the lugs of the corner parts and serve to connect the corner parts firmly to the sectional pieces.
The decoration frame according to the invention can be produced in a highly advantageous way from a
