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.

The present invention relates to a mechanical system for stabilization on the floor for vehicles on castors (for example a surgical assistance robot used in an operating room) that can adopt two stable states, i.e. disengaged, the vehicle resting on the castors, and activated, the vehicle being immobilized on the floor, respectively. According to the invention, the stabilization system comprises: feet for resting on the floor, movable between a first retracted position, at a distance from the floor, and a contact position ensuring the immobilization of the vehicle through mechanical friction against the floor; means for mechanically controlling said supporting feet, said control means being movable between two stable positions corresponding to the activated and disengaged states; mechanical means for transmitting the displacement of the control means simultaneously to all the supporting feet.

An electric vehicle has a structure mounted on balls which are arranged for rolling on the ground, wherein an actuating roller is associated with each ball. The roller-supporting structure is rotatably mounted about a substantially vertical axis within a main supporting structure which is rigidly connected to the ball-supporting member. The main support structure carries a first electric motor for controlling the rotation of the roller-supporting structure about the substantially vertical axis, while the roller-supporting structure carries a second electric motor for controlling the rotation of the roller about its axis.

A telescoping wheel assembly includes a base body, a wheel set and an elastic member. The base body includes a receiving groove. The wheel set is connected to the receiving groove and selectively positioned at an outward position or an inward position relative to the receiving groove. The wheel set includes a wheel axle and a wheel body. The wheel body is connected to an outside of the wheel axle. The elastic member is disposed in the receiving groove and abutted against the base body and the wheel set. When the wheel set is positioned at the outward position, the elastic member provides a buffering elastic force to the wheel set. When the wheel set is positioned at the inward position, the elastic member provides a pushing elastic force to the wheel set.

There is described a caster wheel support assembly for a wheelchair, the caster wheel support assembly having a first section configured to be securable to a frame member of the wheelchair and a second section configured to hold a swivel member coupled to a caster wheel. The caster wheel support assembly has a holding member designed as a collet configured to hold a first portion of the swivel member, in which first portion extends along a first axis. A second portion of the swivel member, which is coupled to the caster wheel, extends away from the first portion along a second axis, in which second axis forms an angle relative to the first axis. The holding member and swivel member are configured such that the first portion of the swivel member is supported by the holding member to selectively allow rotation of the swivel member relative to the holding member about the first axis and thereby cause adjustment of a camber of the caster wheel. The collet is configured to selectively allow clamping of the swivel member onto the holding member, thereby preventing rotation of the swivel member relative to the holding member, and release of the swivel member with respect to the holding member, thereby permitting rotation of the swivel member relative to the holding member.

A mounting unit for adjustably mounting an add-on piece to a frame, in particular of a wheelchair, includes at least one drum receiving unit having at least one aperture and female thread. The drum receiving unit is an integral part of the frame or adapted to be attached to the frame. At least one drum assembly has at least one hole and a male thread. At least one bolt is part of the add-on piece or adapted to be mounted therewith to hold the add-on piece. The drum receiving unit is adapted to receive the drum assembly. The female thread mates with the male thread and allows an alignment of the position of the hole with respect to the aperture, such that the bolt can be inserted through the aperture at least partly into the hole. The drum receiving unit with the drum assembly and/or the drum assembly with the bolt comprises a detachable form fit connection. At least one of the drum receiving unit, the drum assembly and/or the bolt comprises a detachable force fit connection with respective mating component.

A support assembly includes a body and a bearing assembly. The body defines a first opening. The bearing assembly is selectively repositionable within the first opening. The bearing assembly includes a housing, a socket, and a ball. The housing defines a second opening. The socket is positioned at least partly within the second opening and coupled to the housing. The ball bearing is positioned within the socket. The ball bearing is configured to rotate with respect to the housing. The bearing assembly is selectively repositionable between a first position, where the ball bearing extends from the body, and a second position, where the ball bearing does not extend from the body.

A removable transport caster assembly secured to side to side beams or front to back beams in a data center cabinet in a data center. The removable transport caster assembly is temporarily installed on the cabinet to enable the cabinet to be relocated to another location in the data center. The removable transport caster assembly includes a transport caster and a transport caster bracket secured to the transport caster. The transport caster has a mounting plate, a mounting bracket extending from the mounting plate, a lifting plate pivotally connected to the mounting plate, a lifting lever pivotally connected to the mounting bracket and a wheel assembly. The transport caster bracket secures the transport caster to the cabinet when relocation of the cabinet is desired.

A work vehicle includes a pair of left and right pivotal connecting units provided on a front frame, a caster wheel, a caster axle and a caster bracket connected to the pivotal connecting unit. The caster bracket includes side walls supporting the caster axle, a top wall extending rearwards from the upper side of the caster wheel and interconnecting the left side wall and the right side wall, and left and right cover portions for covering gaps between the side walls and the caster wheel.

A support assembly includes a body and a bearing assembly. The body defines a first opening. The bearing assembly is selectively repositionable within the first opening. The bearing assembly includes a housing, a socket, and a ball. The housing defines a second opening. The socket is positioned at least partly within the second opening and coupled to the housing. The ball bearing is positioned within the socket. The ball bearing is configured to rotate with respect to the housing. The bearing assembly is selectively repositionable between a first position, where the ball bearing extends from the body, and a second position, where the ball bearing does not extend from the body.
