Abstract
A removable frame is detachably connected to a supporting frame by a connection having a plurality of spaced apart vertically extending sleeve-like members mounted on the removable frame. Upwardly projecting members are mounted at the periphery of the supporting frame and telescope into each of the sleeve-like members. A horizontal tubular housing attached to each sleeve-like member carries a locking element which cooperates with its upwardly projecting member to form a positively locked connection between the removable and supporting frame.
Claims1
Apparatus for detachably connecting a removable frame to a supporting frame of a vehicle which comprises:
- (a) a plurality of spaced apart, vertically extending sleeve-like members mounted on said removable frame with the lower ends of said sleeve-like members being beveled to provide downwardly and outwardly flaring lower end portions,
- (b) an upwardly projecting member having a tapered upper end portion mounted on said supporting frame in position to telescope into the downwardly and outwardly flaring lower end portion of each of said sleeve-like members,
- (c) a horizontal tubular housing mounted on one side of each said sleeve-like member and projecting outwardly thereof,
- (d) a passageway through each said sleeve-like member in axial alignment with said tubular housing,
- (e) a locking element having an annular recess therein mounted for axial movement in said tubular housing selectively from a first position outwardly of said sleeve-like member to a second position inwardly of said sleeve-like member;
- (f) a recess in said upwardly projectng member in alignment with said passageway with the uppermost wall of said recess in position to receive a notch provided at the inner end of said locking element upon movement of said locking element to said second position,
- (g) a compression spring urging said locking element toward said second position and into engagement with said recess in said upwardly projecting member,
- (h) there being an opening through one side of said horizontal tubular housing in alignment with said annular recess in said locking element when said locking element is in said first position,
- (i) a pin-like member extending through said opening in position to engage said annular recess and positively retain said locking element in said first position,
- (j) an axially extending slot in said locking element having one end thereof communicating with said annular recess and receiving said pin-like member upon movement of said locking element to said second position, and
- (k) a handle carried by the outer end of said locking element for selectively imparting axial and rotary motion thereto.
