Abstract
A utility cart has four corner posts, a handle having a pair of elongate legs and coupling plugs for positioning the distal ends of the handle legs in aligned proximate disposition relative to a pair of corner posts. Support members engage the exterior of the corner posts against axial movement relative thereto and interlock with the handle legs thus to secure the corner posts to the handle. The support members also serve to support a corner of a shelf to each of the four corner posts.
Claims29
A utility cart comprising:
- a shelf;
- first and second pairs of corner posts;
- a handle having a pair of elongate legs;
- coupling means for positioning the distal ends of said handle legs in aligned, proximate disposition with respect to the ends of said first pair of corner posts;
- first support means adapted to engage the exterior of each of said first pair of corner posts against axial movement relative thereto;
- second support means adapted to engage the exterior of each of said second pair of corner posts against axial movement relative thereto;
- and
- means associated with said first support means and the distal ends of said handle legs to interlock said handle and said first support means, whereby said handle and said first pair of corner posts are fixed against removal from said aligned, proximate disposition and whereby said first and second support means engaging respectively said posts of said first and second pairs of corner posts are adapted to support said shelf in horizontal dispostion therebetween.

A utility cart comprising:
- first and second pairs of corner posts, the posts of at least one of said pairs being formed with a hollow tubular section at one end thereof;
- a U-shaped handle having a pair of elongate legs, the distal ends of which are formed with a hollow tubular section;
- coupling means formed with end sections adapted to fit, respectively, into said hollow tubular sections of said one of said pairs of corner posts and said sections of said handle;
- and
- support means adapted to engage the exterior of said posts against axial movement relative thereto thus to support a shelf in horizontal disposition between said corner posts, and being formed with means for interlocking with the distal ends of said handle thus to lock said handle against removal from said one of said pairs of corner posts.
2 more elements
A utility cart comprising:
- a pair of corner posts, each of said corner posts being formed with a recess;
- a handle having a pair of elongate legs;
- coupling means for positioning the distal ends of said handle legs in aligned, proximate disposition with respect to the ends of said corner posts;
- support means adapted to engage the exterior of said corner posts against axial movement relative thereto, each said support means being formed with a corresponding projection adapted to engage with the recess of a corner post;
- and
- means associated with said support means and the distal ends of said handle legs to interlock said handle and said support means, said means to interlock said handle and support means including a button extending laterally of each support means and an opening formed in the distal ends of said handle legs and adapted to receive said button of the associated support means, whereby said handle and said corner posts are fixed against removal from said aligned, proximate disposition.

A utility cart comprising:
- a pair of corner posts;
- a handle having a pair of elongate legs;
- coupling means for positioning the distal ends of said handle legs in aligned, proximate disposition with respect to the ends of said corner posts, the distal ends of said handle legs and opposing ends of said corner posts being tubular sections and each said coupling means having end sections adapted to fit, respectively, into said tubular sections of said legs and a pair of corner posts, said coupling means having a radially extending flange between the ends of said coupling means abutting the ends of said legs and corner posts to establish said coupling means between each leg and its associated corner post;
- support means adapted to engage the exterior of said corner posts against axial movement relative thereto;
- and
- means associated with said support means and the distal ends of said handle legs to interlock said handle and said support means, whereby said handle and said corner posts are fixed against removal from said aligned, proximate disposition.
