1. Field of the Invention
The present invention relates to shelving, in particular, shelving consisting of components which are assembled with securing elements and further comprising vertical and horizontal compartment dividers.
2. The Prior Art
It is known in the art to connect shelves consisting of individual components such as horizontal and vertical compartment dividers, shelf posts and back walls by means of screws, rivets, or by welding. A method frequently employed for assembling shelves comprises securing the shelf bottoms with screws between vertical posts. Another frequently used method is to suspend so-called compartment supports in vertical posts, or to screw such supports into the latter. The individual compartment bottoms are then secured to such supports by means of screws.
Another method for constructing shelves makes use of mounting supports, such as angle sections which are located on vertical walls on the left and right sides having defined spacings. Compartment bottom components of the shelf are then secured to the supports using screws, rivets or welding.
A shelf-like rack with compartment bottoms is known from DE 89 14 430 U1, where a rearward extension of a compartment bottom projects through a slot and into a back wall. The rearward extension has an arresting slot terminating with the back wall. A T-shaped locking element is inserted through the slot, and prevents the compartment bottom from moving. Because of its overall construction, this known rack, which is made from corrugated board, is only suitable for receiving goods of a light weight. Furthermore, the edges in the slide-in area are not rounded.
The known designs of larger shelves all require tools and securing elements to assemble and stabilize the shelves. Furthermore, the compartment divisions formed by the assembly contain sharp edges on all sides. In the corner areas of the compartments, support sections, securing elements or other applications lead to interfering edges that may cause problems when the compartments of the shelf are loaded with sensitive goods, or when the latter are removed from the shelf. In addition, the securing elements may reduce the amount of useable storage space. Furthermore, disposal of those shelves which are no longer needed creates problems.
It is therefore an object of the present invention to provide a component shelf system which can be easily assembled and stabilized without the help of tools.
It is a further object of the invention to provide a component shelf which has compartments without sharp edges along the circumference, and horizontal and vertical compartment dividers with rounded edges in the slide-in areas. Furthermore, the horizontal and vertical compartment dividers are interwoven with each other at the points of intersection using a splint.
It is a final object to provide a strong shelf made from one type of material.
To achieve these objects, stabilizing elements such as angle sections, screws or rivets have been eliminated. This yields surfaces that extend around the compartment divisions with no sharp edges. Furthermore, in the junctions between the horizontal and vertical compartment divisions, a splint is inserted between the parts of the folded vertical compartment division. This not only increases the stability of the entire shelf with the horizontal compartment divisions, but safely prevents lateral movement of the vertical edges of the vertical compartment divisions.
The invention makes use of two tabs with bores which are arranged on the edges of the side wall and on the horizontal and vertical compartment divisions, through which securing bars are installed in the assembled shelf. Thus it is possible to assure an extremely stable connection between the components of the shelf when the components are assembled and fixed by the securing bars.
Other objects and features of the present invention become apparent from the following detailed description considered in connection with the accompanying drawings which disclose the embodiments of the present invention. It should be understood, however, that the drawings are designed for the purpose of illustration only, and not as a definition of the limits of the invention.
Turning now in detail to the drawings,
Side walls 2 and 3, top wall 5, bottom wall 4 as well as the horizontal compartment divider 6 and vertical compartment divider 7 consist of folded rectangularly shaped cuts from cellular plastic boards each forming a rounded folding edge 8. Using this process, the shelf does not have any sharp edges on the circumferential surfaces of the stabilizing elements or the like as the edges 8 are always rounded.
Side walls 2 and 3 contain at least one horizontal receiving slot 36 and at least one tab 9. Horizontal compartment divider 6 and vertical compartment divider 7 each have at least one tab 9 on one edge of the folded cuts, whereby tab 9 of side walls 2 and 3 are inserted into at least one side receiving slot 10 in back wall 1 and at least one vertical receiving slot 37 in bottom wall 4 and top wall 5 of component shelf system 30. To add further strength, horizontal compartment divider 6 and vertical compartment divider 7 can be secured to each other through a horizontal divider slot 13 on horizontal compartment divider 6 and a vertical divider slot 14 on vertical compartment divider 7.
Top wall 5 and bottom wall 4 contain at least one vertical receiving slot 37 to receive tab 9 from any vertical member. The location and number of vertical receiving slots 37 vary with the number of vertical compartment dividers 7.
After component shelf system 30 has been assembled, tabs 9 on the side walls 2 and 3 and on vertical compartment divider 7 are folded over on the underside and fused with bottom wall 4. It is, of course, possible to use as many vertical compartment dividers 7 and horizontal compartment dividers 6 as desired. The horizontal compartment dividers may also be inserted at a downward angle, away from the top wall.
As shown perspectively in FIG. 14 and by a detail of
Of course, the features of the invention can be applied in connection with shelves where no provision is made for additional horizontal compartment dividers as is formed only by the bottom and the top components.
While several embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention as defined in the appended claims.
