US Patent:

55199160, May 28, 1996

Filed:

Mar 13, 1995

Appl. No.:

8/404194

Inventors:

Tommy D. Mainard - Wagoner OK

Assignee:

UNR Industries, Inc. - Chicago IL

International Classification:

B65B 504

US Classification:

16 35R

Abstract:

In a wheel and brake assembly for a wheeled cart, such as a shopping cart or a luggage cart, a horn is mountable to the cart so as to extend downwardly from the cart. A wheel defining a wheel axis and including a hub is journalled to the horn at the hub. A pin projects from the hub but clears the horn when the wheel is rotated. A bracket is mounted pivotably to the horn so as to be pivotable over a limited range, between an inoperative position and an operative position, with a tang projecting axially from the bracket. The tang is arranged to engage the pin so as to brake the wheel against further rotation in one rotational sense, once the bracket has been pivoted to the operative position, if the wheel is rotated by less than one full revolution in the same rotational sense. The pin is arranged to engage the tang so as to pivot the bracket from the operative position, and so as to release the wheel, if the wheel is rotated by less than one full revolution in the opposite rotational sense.

International Classification:

B62B 1100

US Classification:

280 33992

Abstract:

In a shopping cart comprising an undercarriage, a handle having two tubular portions extending generally upwardly from the undercarriage, and a basket mounted to the undercarriage and the handle, the basket has a gate hinged to the tubular portions of the handle via a hinge wire extending along an upper edge of the gate. Two tubular sleeves are fixed to the handle, each extending through an inwardly opening aperture in an associated one of the tubular portions of the handle. Each end portion of the hinge wire extends into one of the tubular sleeves. Two rivets are fixed to the handle, each having an outside head, a tubular shank extending inwardly through an outwardly opening aperture in an associated one of the tubular portions of the handle and through an associated sleeve, and a mandrel drawn outwardly into the shank so as to expand the shank and the associated sleeve. As disposed within the tubular portions of the handle, the mandrels of the rivets permit but limit axial movement of the hinge wire relative to the tubular sleeves, the tubular portions of the handle, and the retaining structures. In one contemplated embodiment, each tubular sleeve has an annular flange bearing against an outer margin of an associated one of the outwardly opening apertures.

Two rivets are employed, each having a head bearing against one such tubular portion of the handle, a tubular shank extending inwardly through an outwardly opening aperture in the same handle portion, and a mandrel drawn outwardly into the shank so as to expand the shank. As disposed within the tubular portions of the handle, the mandrels of the rivets limit axial movement of the hinge wire and retain the end portions of the hinge wire within the tubular portions of the handle, approximately at a centered position.

International Classification:

US Classification:

280 33991

Abstract:

In a shopping cart comprising a wheeled chassis, a handle structure including two handle uprights extending upwardly from the wheeled chassis, and a basket supported on the wheeled chassis and fastened to the handle uprights, two clips are employed for fastening the basket to the wheeled chassis. Each clip is fastened to an associated, generally horizontally extending portion of a frame of the wheeled chassis, beneath one of the side walls of the basket. Each clip has an upper, flanged end, which extends at least partly into an associated recess provided in one of the side walls of the basket and a lower, curved end, which conforms generally to and extends at least partly beneath the associated, generally horizontally extending portion of the frame. The frame of the wheeled chassis includes a tubular member defining the generally horizontally extending portions, to which the clips are riveted.
