A height adjustable support comprising a three-sided support channel, a cylindrical support post positioned within the support channel and at least one saddle brace positioned within the support channel and to partially surround the cylindrical support post. In the present invention, the downward force resulting from the weight of the equipment results in static friction between the saddle brace and the cylindrical support post that is sufficient to hold the equipment surface at a desired height. The height adjustable support may be implemented into hygienically designed food processing equipment to eliminate undesirable bacteria harboring surfaces and to improve height adjustability of the equipment.

A retractable caster assembly includes a frame and a caster wheel assembly. The caster wheel assembly has a wheel and two guide members. The assembly is configured with the guide members movable along slots within the frame so that when the caster wheel assembly is at a first end of the slots the wheel is in a retracted position substantially within the cavity, and so that when the caster wheel assembly is at a second end of the slots the wheel is in an extended position extending from the cavity. A package may have at least one cavity, each cavity for receiving a retractable caster wheel assembly to make a wheeled package.

A caster wheel adjustment assembly for a wheelchair includes a first mounting member coupled to a wheelchair frame member, a second mounting member coupled to a caster wheel, and an angle adjustment member defining a first side opposite a second side. The first side defines a plurality of first projections, and the second side defines a plurality of second projections. The first plurality of projections includes a different number of projections than the second plurality of projections. The angle adjustment member is configured to interlock with first mounting member and the second mounting member. The first plurality of projections selectively interlock with a third plurality of projections on the first mounting member, and the second plurality of projections selectively interlock with a fourth plurality of projections on the second mounting member.

A dolly comprising a chassis, a castor having a fork and a wheel rotatably mounted to the fork, and a fastener for fixing the fork of the castor to the chassis of the dolly. The fastener comprises a head which is shaped to the peripheral shape of the wheel of the castor.

A caster wheel assembly includes a wheel mounted for rotation about a horizontal axis within a wheel carriage such that the wheel rotates about the horizontal axis with respect to the wheel carriage. The wheel carriage is positioned within a retention ring such that the wheel carriage can rotate about the vertical axis with respect to the retention ring. The wheel carriage also has an opening on the bottom surface such that the wheel can make contact with the ground. The horizontal axis about which the wheel rotates is offset from the vertical axis about which the wheel carriage rotates. An outer carriage may be included such that the outer carriage is positioned within the retention ring and the wheel carriage is positioned within the outer carriage. The outer carriage would be able to rotate about the vertical axis with respect to both the retention ring and the wheel carriage.

The present invention provides a wheel assembly for a luggage bag. The wheel assembly comprises a mounting plate, a fork, at least one wheel and at least one magnet. The mounting plate is adapted to be configured on a peripheral portion of the luggage bag. The fork extends from the mounting plate and at least one wheel is connected to the fork. The magnet is adapted to be arranged on an inner portion of the luggage bag opposite to the corresponding mounting plate. When the luggage bag is brought into proximity with the mounting plate, the magnet inside the luggage bag is attracted to the mounting plate and securely connects with the mounting plate, thereby fastening the wheel assembly to the luggage bag.

Disclosed is an assembly type fixture whose assembling is easy and convenient, and an assembling part of an assembly type fixture. A square pipe having an insertion hole in a front surface plate, and a coupling member having an engagement element that is inserted into the square pipe from an end opening of the square pipe are provided, the engagement element has a pair of long side plate and short side plate that oppose each other and have different front-to-rear lengths from each other, and an intermediate plate that connects the long side plate and the short side plate, and is abutted with and arranged on an inner surface of the square pipe, and the insertion hole is arranged close to the short side plate side.

This application relates to a roller device. The device comprises: a roller; and a roller axle, the roller axle comprises: an axle portion configured to mount the roller such that the roller is rotatable about the axle portion; and a riveting portion at a mounting end of the roller axle with respect to an axial direction of the roller axle, and extending from the mounting end in a direction away from the axle portion, wherein, when the roller device is pressed against a carrier under force, the riveting portion can pierce the carrier such that the roller axle is riveted with the carrier through the riveting portion.

A support frame for a sheet conveying apparatus includes a bottom plate that includes a first member having a first surface portion and a first wall portion and a second member having a second surface portion and a second wall portion, a support rod that is fixed to the bottom plate, and a plurality of installation members that is fixed to the bottom plate and installs the sheet conveying apparatus. The second member is fixed to the first member by the second wall portion overlapping and being joined to the first wall portion on an outer side of the first wall portion.

A caster wheel adjustment assembly for a wheelchair includes a first mounting member coupled to a wheelchair frame member, a second mounting member coupled to a caster wheel, and an angle adjustment member defining a first side opposite a second side. The first side defines a plurality of first projections, and the second side defines a plurality of second projections. The first plurality of projections includes a different number of projections than the second plurality of projections. The angle adjustment member is configured to interlock with first mounting member and the second mounting member. The first plurality of projections selectively interlock with a third plurality of projections on the first mounting member, and the second plurality of projections selectively interlock with a fourth plurality of projections on the second mounting member.
