ABSTRACT:
FIELD OF THE INVENTION
The invention herein pertains to mattress and box spring supports as are used in conventional beds. Particularly, the invention concerns the use of preformed corner connectors in mattress supports and box spring bases.
DESCRIPTION OF THE PRIOR ART AND OBJECTIVES OF THE INVENTION
Manufacturers of furniture components such as mattress supports and box spring bases in recent years have fallen under great competitive pressure in recent years due to foreign imports, low local unemployment and increased local competition. As a result, many manufacturers have eliminated conventional box springs that are normally used for mattress supports in beds and are instead supplying “built-up” mattress supports formed from wood. These built-up mattress supports are formed in rectangular fashion and are then sawed at each corner to fairly duplicate the rounded corners of conventional mattresses. Pine and other lightweight woods are used with square corner posts in the initial construction of the mattress supports after which the corners are band-sawed, often with difficulty and sometimes with sufficient inaccuracy to require additional fabrication or repair.
In addition to built-up mattress supports as aforedescribed, metal box spring manufacturers are utilizing relatively thin wooden bases to reduce weight and costs of box springs. Such bases again are formed from built-up wooden components which are first assembled in rectangular form with 90° corners which are subsequently rounded with a band saw or the like. Rounding of the corners is time consuming and requires a skilled worker, increasing the cost of labor and production.
Thus with the aforesaid problems and disadvantages of previous manufacturing and construction methods, the present invention was conceived and one of its objectives is to provide a preformed corner connector and method for use in mattress support and box spring base assembly methods which is easy to incorporate into conventional manufacturing techniques.
It is still another objective of the present invention to provide a corner connector which allows a relatively unskilled laborer to accurately assemble a mattress support with little training or skill.
It is yet another objective of the present invention to provide a corner connector for a mattress support which is inexpensive to manufacture yet provides an aesthetically pleasing, uniform result.
It is a further objective of the invention to provide a preformed corner connector which can be used for a box spring base.
It is still another objective of the invention to provide a corner connector which can be preformed in mass quantities such as through plastic molding to exact size requirements.
It is yet another objective of the present invention to provide a box spring base which is relatively light in weight and inexpensive to manufacture.
Various other objectives and advantages of the present invention will become apparent to those skilled in the art as a more detailed description is set forth below.
SUMMARY OF THE INVENTION
The invention herein pertains to corner connectors such as manufactured from plastic, wood or other suitable components. The corner connectors are preformed, i.e. completed before initial assembly of a mattress support or box spring base, as required. In one embodiment a corner connector for a mattress support includes a series of planar members of different sizes which are joined to a main central block and assembled with a coincidental arcuate rear surface or corner.
In another embodiment, a preformed corner connector for a box spring base is provided. The corner connectors are formed such as by injection molding of a suitable plastic as is conventional in the trade.
