BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to bamboo or wood storage devices and more particularly, to a reinforcing frame structure for a storage rack.
(b) Description of the Prior Art
Many materials such as wood, bamboo, plastics, stainless steel, etc., are used for making storage boxes, racks, cabinets, drums, racks and etc. for keeping things. Wood or bamboo storage devices show an antique beauty. Small storage devices of wood or bamboo material are widely invited for storing jewelries and other small items.
A wood or bamboo storage rack generally comprises a multilateral top open frame, a multilateral bottom open frame, upright posts connected between the multilateral top open frame and the multilateral bottom open frame at each of the multiple corners, and wall panels fastened to each of the multiple sides. However, the dynamic analysis shows that the corner area of a wood or bamboo storage rack is the weakest point where a concentration of stress occurs. Because wood and bamboo are elastic when compared to metal, a wood or bamboo storage rack of the aforesaid design is less stable.
SUMMARY OF THE INVENTION
The primary purpose of the present invention is to provide a reinforcing frame structure for a storage rack, which has the structural strength of each of the four corners reinforced.
To achieve this and other objects of the present invention, the reinforcing frame structure comprises top and bottom multilateral open frame units, a plurality of upright supports respectively made of an angle bar and vertically connected between the top and bottom multilateral open frame units at each of multiple corners of the top and bottom multilateral open frame units, and reinforcing pins respectively transversely fastened to the top and bottom multilateral open frame units and the upright supports at each of the multiple corners to reinforce the structural strength.
Further, each multilateral open frame unit comprises an inner multilateral open frame, an outer multilateral open frame surrounding the inner multilateral open frame, and two spacer blocks set in between the outer multilateral open frame and the inner multilateral open frame at each of the multiple corners at two sides of each of the upright supports.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIGS. 1 and 2, a reinforcing frame structure in accordance with a first embodiment of the present invention is shown comprising a rectangular open frame unit 1 (only a part of the rectangular open frame unit is shown in the drawings), an upright support 2, and a reinforcing pin 3. The rectangular open frame unit 1 comprises an inner rectangular open frame 12, an outer rectangular open frame 11 surrounding the inner rectangular open frame 12, two spacer blocks 13 set between the inner rectangular open frame 12 and the outer rectangular open frame 11 at two sides at one of the four corners of the rectangular open frame unit 1 and bonded thereto with an adhesive, and a reinforcing angle block 14 bonded to the inner side of the inner rectangular open frame 12 at one corner corresponding to the spacer blocks 13. The upright support 2 is an angle bar inserted into the gap between the inner rectangular open frame 12 and the outer rectangular open frame 11 at one of the four corners of the rectangular open frame unit 1 and stopped between the two spacer blocks 13 and bonded thereto with an adhesive, having the topmost edge thereof kept in flush with the inner rectangular open frame 12, the spacer blocks 13 and the outer rectangular open frame 11. Further two oblique through holes 141 are made through the reinforcing angle block 14, the inner rectangular open frame 12, the spacer blocks 13 and the outer rectangular open frame 11. The reinforcing pin 3 is press-fitted into the oblique through holes 141 and transversely extended through two sides of each of the outer rectangular open frame 11, the inner rectangular open frame 12 and the reinforcing angle block 14 to reinforce the structural strength of the rectangular open frame unit 1. Further, the inner rectangular open frame 12, the spacer blocks 13 the outer rectangular open frame 11 and the reinforcing angle block 14 may be made of bamboo or wood.
Referring to FIGS. 3 and 4, a reinforcing frame structure in accordance with a second embodiment of the present invention is shown comprising a rectangular open frame unit 1 (only a part of the rectangular open frame unit is shown in the drawings), an upright support 2, and two reinforcing pins 3. The rectangular open frame unit 1 comprises two inner rectangular open frames 12 arranged at different elevations, an outer rectangular open frame 11 surrounding the upper inner rectangular open frame 12, two spacer blocks 13 set between the upper inner rectangular open frame 12 and the outer rectangular open frame 11 at two sides at one of the four corners of the rectangular open frame unit 1 and bonded thereto with an adhesive, a reinforcing angle block 14 bonded to the inner side of the inner rectangular open frames 12 at one corner corresponding to the spacer blocks 13. The upright support 2 is an angle bar inserted into the gap between the upper inner rectangular open frame 12 and the outer rectangular open frame 11 at one of the four corners of the rectangular open frame unit 1 and stopped between the two spacer blocks 13 and bonded thereto with an adhesive, having the topmost edge thereof kept in flush with the upper inner rectangular open frame 12, the spacer blocks 13 and the outer rectangular open frame 11. Further oblique through holes 141 are made through the reinforcing angle block 14, the inner rectangular open frames 12, the spacer blocks 13 and the outer rectangular open frame 11. The reinforcing pins 3 are press-fitted into the oblique through holes 141 and transversely extended through two sides of each of the outer rectangular open frame 11, the upper inner rectangular open frames 12 and the reinforcing angle block 14 to reinforce the structural strength of the rectangular open frame unit 1.
FIG. 5 illustrates the present invention applied to a storage rack 4. The storage rack 4 comprises two rectangular open frame units 41 horizontally arranged at top and bottom sides, four upright supports 42 connected between the two rectangular open frame units 41 at the four corners, and reinforcing pins 3 respectively transversely fastened to the rectangular open frame units 41 and the upright supports 42 at the four corners at the top and bottom sides to reinforce the structural strength of the storage rack 4.
FIG. 6 illustrates the present invention applied to a multi-later storage rack 4 in which reinforcing pins 3 are respectively transversely fastened to the rectangular open frame units 41 and the upright supports 42 at the four corners at different elevations to reinforce the structural strength of the storage rack 4.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
