ABSTRACT:
FIELD OF THE INVENTION
This invention relates to the field of message boards, and more particularly relates to accessories attachable to message boards and mechanisms for attaching such accessories to message boards.
BACKGROUND OF THE INVENTION
Various forms of message boards are known in the art. The conventional bulletin board, which is generally made from a cork or other tack penetrable material, has been used to pin or tack notes or other things to it. Other message boards include dry-erase boards which are essentially smaller versions of the big dry-erase boards used like blackboards (or more accurately “white” boards) in offices and elsewhere. A combination bulletin and dry-erase message board is the subject of Applicant's U.S. Pat. No. 5,527,568.
In addition to the various materials used to comprise the surfaces of these message boards, it has also been known to attach various accessories to the surfaces and edges of the message boards. Trays, storage receptacles, and various types of holders are typical of these types of accessories. These accessories are typically attached to the frames and surfaces of the message boards by adhesive bonding, nailing, screwing, and similar techniques, or, alternatively, by detachably securing the accessory to the frame. Many of these arrangements are relatively complicated or cumbersome to use, and many do not provide a firm attachment such that the accessory is held firmly to the frame of the message board by a positively locking mechanism. There are also only a limited number of types of accessories available in the prior art which are capable of providing only a limited number of functions.
SUMMARY OF THE INVENTION
It is accordingly a principal object of the present invention to provide an improved message board having a frame adapted to receive and firmly retain various accessories in a convenient manner.
In a second aspect, a grip comprises a generally “C”-shaped body having a tip at one end and a lip extension at the other end. The tip is adapted to engage the front channel of the frame, while the lip extension is adapted to engage the rear channel of the frame, to thereby retain the grip on the frame. Various accessories designed to be attached to the frame are formed integrally with the grip.
In a number of additional aspects, several accessories of various designs and capable of performing various functions are provided.
Further objects and advantages of the present invention will become apparent from a consideration of the drawings and ensuing description.
