2 Claims. (01. 248-242) This invention relates to new and useful improvements and structural refinements in adjustable shelf brackets, and the principal object of the invention is to provide a device of the character herein described, such as may be conveniently and effectively employed for supporting shelves in a horizontal position regardless of the relative angular disposition of the wall, or the like, to which such shelf is attached.
A further object of the invention is to provide an adjustable shelf bracket which is simple in construction, which may be quickly and easily adjusted, and which will readily lend itself to economical manufacture.
Another object of the invention is to provide an adjustable shelf bracket which will not easily become damaged and which is otherwise Well adapted for the purpose for which it is intended.
With the above more important objects in view, and such other objects as may become apparent as this specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:
Figure 1 is a perspective view of the invention.
Figure 2 is a perspective View of one of the blocks used in the invention.
Figure 3 is a perspective view of a hinge member used therein.
Figure 4 is a perspective view of a further hinge member, and
Figure 5 is a fragmentary perspective view of a strut used in the invention.
Like characters of reference are employed to designate like parts in the specification and throughout the several views.
Referring now to the accompanying drawings in detail, the invention consists of an adjustable shelf bracket designated generally by the reference character In, the same embodying in its construction an elongated wall member H and an elongated shelf member I2, these members being formed from any suitable material and preferably having an H-shaped cross sectional configuration, as is best shown in the upper left hand portion of the accompanying Figure 1.
The wall member H is formed with a plurality of apertures l3, whereby it may be conveniently secured by means of suitable bolts, screws, or the like (not shown) to the wall or to some other suitable supporting structure.
One end of the wall member I l is provided with a hinge member I4 which coacts with a further hinge member [5 provided at one end of the shelf member l2, the hinge members l4, [5 being pivotally connected together by a suitable pin l5, as will be clearly apparent from the accompanying drawings. As will be clearly apparent from the accompanying Figure 3, the hinge members l4, l5 are formed with integral leg portions I! which are receivable in the grooves [8 of the wall and shelf members ll, [2, the members l4, l5 being secured to the members ll, [2 respectively by welding or the like.
A block l9, formed with a T-slot 20, is slidable on the shelf member I2, while a further block 2|, formed with a similar slot 22, is slidable on the wall member I l. The two blocks 19, 2| are similar in construction, both being provided with yokes 23 to which are pivotally connected the end portions 24 of a strut 25 by means of suitable pins 26.
A set screw 21 is provided in each of the blocks I9, 2| whereby the blocks may be rigidly yet adjustably secured in any desired position upon their respective members [2, l l, as will be clearly apparent. Needless to say, the set screws 21 are frictionally engageable with the surfaces of the members 12, II, so that the blocks l9, 2| may be adjustably secured in position.
When the invention is placed in use, the member II is secured to a wall or to some other supporting structure and a shelf, or the like (not shown), is similarly secured to the member l2.
Thereupon, the position of the blocks I9, 2| with respect to the members l2, ll may be adjusted so that the shelf mounted upon the member I2 is supported in a substantially horizontal position regardless of the angular disposition of the wall to which the member ll may be attached. When this adjustment of the brackets has been obtained, the set screws 2'? of the blocks l9, 2! may be tightened so that the shelf will be supported in the horizontal position, as will be clearly apparent.
It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and accordingly, further description thereof at this point is deemed unnecessary.
While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
Having described the invention what is claimed as new is:
