Abstract
Abstract An improved system for fixedly mounting a case or the like box-shaped article onto the body of a motorcar is disclosed. The case is first placed on a mounting base fixedly secured to the body of motorcar by fitting a plurality of projections into holes on the mounting base and thereafter by operating a displacing device with the aid of a key the case is displaced relative to the mounting base so that the former is fixedly mounted on the latter. Each of the projections is formed with a V-shaped annular groove and each of the holes includes a larger diameter portion of which diameter is dimensioned larger than that of the projections and a smaller diameter portion formed by cutting a part of the larger diameter portion with a circle having the diameter dimensioned smaller than that of the larger diameter portion. Thus, the case is immovably mounted on the mounting base when the periphery of the smaller diameter portions of the holes are wedged between the upper and lower inclined parts in the V-shaped annular grooves on the projections. The case is normally constituted by a combination of upper cover and lower cover both of which are connected to one another by means of a plurality of fastening bolts of which head serves as a projection. The displacing device includes a tongue on the mounting base and a screw on the case and the latter is rotated by the key which is actuated from the outside of the device.

Claim 1
Independent Claim
221 words
In a system for fixedly mounting a case or the like box-shaped article, the improvement comprising: engaging means for in combination, a case or the like and a mounting base, engaging one surface of the case to one surface of the mounting base, said engaging means comprising a plurality of column-shaped projections with an annular groove formed thereon respectively, said projections provided on either one of the one surface of the case or the one surface of the mounting base, and a plurality of holes formed on the other one of the one surface of the mounting base or the one surface of the case at the position located opposite to the projections, said holes being formed with a first portion of larger diameter and a second portion of smaller diameter, the periphery of the larger diameter portion of said holes receiving the projections during their insertion into the holes, and displacing means for displacing the case relative to the mounting base after the formed is placed on the one surface of the latter so that the projections are moved into the smaller diameter portions of the openings and are firmly engaged by the latter said displacing means comprising a tongue standing from the mounting base and a locking means at the one surface of the case cooperating with said tongue.
