Abstract
Description
- The present invention relates to a foldable bookcase which can be easily assembled and folded into a compact size.
- Conventional bookcases are made to be a one-piece structure which includes a top board, a bottom board, two sidewalls and one or two front doors. All of the parts are fixedly by nails (for wood boards) or by way of welding (for metal boards). The conventional bookcases are not convenient to be transported and occupy a lot of space which increases cost for the manufactures. As shown in Figs. 9 and 10, a conventional
foldable bookcase 80 includes afront frame 81, arear board 83, afoldable top board 85 and afoldable bottom board 86 both are connected between thefront frame 81 and therear board 83, twosidewalls 82 and twodoors 84. Each of thetop board 85 and thebottom board 86 is composed of twoparts 87 which are pivotably connected to each other bypivots 871 and can be folded along the connection side located at a center of thetop board 85 and thebottom board 86. The other side opposite to the connection side of each of thetop board 85 and thebottom board 86 are pivotably connected to thefront frame 81 and therear board 83 byconnection pieces 872. The two ends of each of theparts 87 include L-shapedengaging plates 88 which are connected toholes 821 of thesidewalls 82. Therefore, thebookcase 80 can be folded into a compact size by folding thetop board 85 and thebottom board 86. - Nevertheless, the folding line, i.e. the connection side is exposed and can be seen from outside of the
bookcase 80 and theengaging plates 88 need extra machining processes to be made on the parts 27 of thetop board 85 and thebottom board 86. Theengaging plates 88 protrude from the parts 27 and exposed so that thebookcase 80 cannot meet requirements of aesthetic purposes. - The present invention intends to provide a foldable bookcase wherein the top board, the bottom board and the two sidewalls can be folded relative to the front frame. Besides, the bookcase of the present invention has no folding lines and engaging plats can be seen from outside of the bookcase.
- The present invention relates to a foldable bookcase that comprises a frame including a top side, a bottom side and two vertical sides connected between the top side and the bottom side. A top board has a first edge plate bent from a front side and two ends of the top board and a first connection portion is bent from a rear side of the top board. The front side of the top board is pivotably connected to the top side of the frame by first pivotable members. A bottom board has a second edge plate bent from a front side and two ends of the bottom board, and a second connection portion is bent from a rear side of the bottom board. The front side of the bottom board is pivotably connected to the bottom side of the frame by second pivotable members. Two sidewalls each have a bent plate extending from a top side, a front side and a bottom side thereof. The two respective front sides of the two sidewalls are pivotably connected to the two vertical sides of the frame by third pivotable members. An L-shaped bent edge is defined in a rear side of each of the sidewalls. A rear board has an inward bent L-shaped connection portion on a top side thereof and an insertion extends from a bottom side and two vertical sides of the rear board. The L-shaped connection portion of the rear board is connected to the a first connection portion of the top board and the insertion on the bottom side and the two vertical sides of the rear board are respectively connected to the bottom side of the frame and the two L-shaped grooves of the two sidewalls.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

Thebent plate 41 on the top side of each of thesidewalls 40 includes ahole 42 so that thebosses 22 on thetop board 20 are engaged with theholes 42 to connect thetop board 20 to the twosidewalls 40 as shown in Figs. 1-1 and 7. - A
rear board 50 has an inward bent L-shaped connection portion 51 on a top side thereof and aninsertion 53 extends from a bottom side and two vertical sides of therear board 50. The L-shaped connection portion 51 of therear board 50 includes a second throughhole 52 and the L-shaped connection portion 51 is connected to the afirst connection portion 23 of thetop board 20 by extending a bolt through the first and second throughholes insertion 53 on the bottom side and the two vertical sides of therear board 50 are respectively connected to the bottom side of theframe 10 and the twogrooves 43 of the twosidewalls 40 as shown in Figs. 6 and 6-1. Twostops 54 extend from an inside of therear board 50 so as to stop two respective distal ends of the L-shaped bent edge 44 of thesidewalls 40 as shown in Figs. 6 and 6-1. - As shown in Fig. 8, the bookcase of the present invention may be equipped with two sliding
doors 70 which are movably engaged with rails connected to thefront frame 10. - The bookcase can be easily assembled and the two
sidewalls 40 are quickly positioned relative to thetop board 20 by thebosses 22 and theholes 42. Thetop board 20, thebottom board 30 and the twosidewalls 40 are able to be pivoted relative to theframe 10 so as to become a thin combination which is benefit for storage and transportation. The pivotable members are not seen from outside of the bookcase so that the bookcase has smooth outer appearance. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
