although the disclosure hereof is detailed and exact to enable those skilled in the art to practice the invention , the physical embodiments herein disclosed merely exemplify the invention which may be embodied in other specific structure . the scope of the invention is defined in the claims appended hereto . referring to fig1 a self - locking mounting clip system 1 is illustrated that includes the present invention . the mounting system 1 is particularly useful for mounting a wide variety of document storage components to vertical supports in a work place environment . for example , the mounting system may be used to assemble a cabinet , represented by reference numeral 3 to a sturdy support structure represented by reference numeral 5 . other typical applications include mounting a paperbasket to a vertical wall panel in an office . thus , it will be understood that the invention is not limited to any particular type of support structure or to the type of component mounted to the support structure . in accordance with the present invention , the self - locking mounting clip system 1 comprises at least one mounting clip 7 and an upright frame member 9 for each mounting clip . the frame members 9 are depicted as having channel cross - sections . however , any shape structural member of sufficient strength and rigidity is acceptable , such as angle irons and h - shaped cross - sectional members . in each instance , the frame member is formed with a series of vertically aligned vertically oriented slots 11 that pass through a front wall 13 of the frame member . the slots 11 are preferably equidistantly spaced , with a land 15 of the frame member material between adjacent slots . to mount the cabinet 3 or other component to the support structure 5 , the mounting clips 7 preferably are fastened to the back side of the cabinet . looking also at fig2 and 3 , each mounting clip comprises a base portion 17 and a series of angled connectors 19 joined to the base . to attach the mounting clip to the cabinet , a suitable flange or similar member is employed . the flange is designed to suit the particular storage component that is to be mounted to the support structure . with a component such as cabinet 3 , a flange 21 that makes a right angle with the base 17 is satisfactory , but other attachment configurations are also acceptable . conventional screws 23 may be used to attach the mounting clip to the cabinet . with particular attention to fig2 each angled connector 19 comprises a short generally horizontal stem 25 and an angular plate 27 . the stem first end 29 is integrally joined to the mounting clip base 17 along the free edge 30 thereof . the angular plate 27 is integrally joined to the stem 25 at the second end 31 thereof . each stem has top and bottom surfaces 33 and 35 , respectively . the angular plate 27 of each angled connector 19 is preferably formed as a parallelogram having an outside end 37 and an opposed inside end 47 that is joined to the stem second end 31 . the angular plate outside end 37 is preferably vertical when the mounting clip 7 is in the operative position shown . the opposed sides 39 and 41 of each angular plate make angles of approximately 45 ° with the stem second end 31 . consequently , the angular plate side 41 and the base free edge 30 form a crotch 46 therebetween . turning to fig4 and 5 , the cabinet 3 is mounted to the support structure 5 by means of the mounting clip system 1 by first aligning the outer ends 37 of the mounting clip angled connectors 19 with the slots 11 in the frame member 9 . the cabinet and mounting clip 7 are then moved horizontally toward the frame until the angular plate ends 37 enter the corresponding slots . to facilitate insertion of the angular plates , the lower corners 43 thereof are chamfered . once the angular plate ends have entered the frame member slots , the cabinet and mounting clip must undergo a vertical downward motion simultaneously with a horizontal motion in order for the angular plates to completely enter the slots , fig5 . consequently , to remove the cabinet from the support structure , a reverse bidirectional motion of the cabinet and mounting clips is required , thereby increasing the difficulty of removing the cabinet from the support structure and decreasing the risk of accidentally dislodging the cabinet . further in accordance with the present invention , the mounting clip 7 is formed with a notch 45 between the base portion 17 and each of the angular plates 27 . each notch 45 is defined by a portion of the free edge 30 of the base , the lower surface 35 of the stem 25 , and a portion of the angular plate end 47 , which is longer than the second end 31 of the stem . the length of the stem bottom surface 35 is slightly greater than the thickness of the wall 13 of the mounting frame 9 . when the mounting clip 7 fully engages the frame member 9 , notches 45 engage the respective lands 15 between the slots 11 . notch and land engagement contribute to the permanence of the connection between the cabinet 3 and the support structure 5 . to remove the cabinet , a three - step procedure is required : the cabinet must be vertically moved to disengage the notches from the frame member lands , the cabinet must be moved simultaneously in horizontal and vertical directions to partially disengage the angular plates 27 from the slots , and the cabinet must be moved in a horizontal direction to completely remove the angular plates from the slots . therefore , removing the cabinet requires a conscientious effort to perform the required sequence of events , and unintentional or accidental removal is unlikely . thus , it is apparent that there has been provided , in accordance with the invention , a self - locking mounting clip system that fully satisfies the objects , aims and advantages set forth . while the invention has been described in conjunction with specific embodiments thereof , it is evident that many alternatives , modifications , and variations will be apparent to those skilled in the art in light of the foregoing invention . accordingly , it is intended to embrace all such alternatives , modifications , and variations as fall within the spirit and broad scope of the amended claims .
a system for mounting storage cabinets and the like to a vertical frame comprises a mounting clip that has a plurality of notched angled connectors . the angled connectors are designed to engage cooperating slots in the vertical frame . the angled nature of the connectors requires that the cabinet be moved in three steps to engage the plates and notches with the vertical frame , thereby reducing the risk of the cabinet becoming accidentally dislodged from the frame .
