A brake system for a patient support apparatus including at least one wheel is disclosed. The brake system comprises a braking mechanism to be operatively coupled to at least one wheel of the patient support apparatus. The braking mechanism includes a first coupling portion movable between a lock position for locking the corresponding wheel, and an unlock position for allowing rotation of the wheel. The brake system comprises an actuating tool comprising a second coupling portion complementary to the first coupling portion of the braking mechanism and allowing removably connecting the actuating tool to the braking mechanism of the patient support apparatus. The first and second coupling portions are adapted for allowing engagement between the braking mechanism and the actuating tool to urge the braking mechanism between the lock and unlock positions, and are further adapted for allowing disengagement of the actuating tool from the braking mechanism.

A patient transport apparatus is provided for use with a retainer of a transport vehicle. The patient transport apparatus comprises a support structure comprising a patient support surface to support a patient. An engagement member is coupled to the support structure and arranged to engage the retainer when unloading the patient transport apparatus from the transport vehicle. A dampener is operable in a standby state or a resistance state such that the dampener provides increased resistance to movement of the patient transport apparatus in the resistance state as compared to the standby state. The resistance state of the dampener is activated by manually moving the patient transport apparatus in a first direction and the standby state is activated by manually moving the patient transport apparatus in a second direction, opposite the first direction.

The present invention relates to a castor wheel structure, comprising a wheel part (18) and a castor wheel house (28), on which a transition element can be mounted, such as a spindle structure (1) or a flange structure (2), which again can be mounted on equipment that is to be made mobile, which wheel part (18) is unilaterally suspended and arranged about a substantially horizontal shaft on the castor wheel house (28).

The present disclosure provides a gantry for an X-ray system. The gantry may include a base section, a lifting section, and a swing section. The base section may be configured to move. A first end of the lifting section may be connected to the base section. A first end of the swing section may be rotatably connected to a second end of the lifting section. A radiation assembly may be disposed on a second end of the swing section.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

A formfitting securing device for a roller has a rotation blocking engagement part which is biased into an engagement position by means of a first spring. The first spring exerts a bias onto the rotation-blocking engagement part both in the engaged position as well as in the nonengaged position, and a bias is achieved in the non-engaged position by acting on the rotation-blocking engagement part by means of a second spring.

A geologic core inspection table includes at least two legs, each including an extending portion for increasing the effective length of each leg, the extending portion at least partially concentrically disposed within or about the leg from which it extends; and a tabletop disposed above and coupled to the legs. The tabletop includes a top surface for receiving a core sample tray. At least one leg may be extended to a different height than at least one other leg.

An actuation assembly includes a torque input element, a torque output element, and a transfer linkage assembly comprising a connector assembly which connects the input element to the output element. The connector assembly includes a first connector having a proximate end and a connector portion. The proximate end of the first connector is the end closer to either the input element or the output element, and the connector portion is further from that same element. The connector assembly also includes a second connector having a proximate end closer to the other of the input element and the output element. The connector portion is further from that same element. The connector portions are selectively joinable to either permit or resist relative longitudinal translation of the first and second connectors. One example application for the actuation assembly is as an actuation assembly for a braking system on a hospital bed.

An article movement system includes an article and at least one ball wheel. The article has first and second article surfaces meeting at a first article edge. The ball wheel is located along the first article edge and includes a ball, a bearing arrangement and a shell. The ball engages a surface underlying the article, the bearing arrangement supports the ball for omni-directional rotational movement, and the shell is located along the first article edge and contains the ball and the bearing arrangement. The shell defines a non-circular ball opening through which a portion of the ball extends to contact the underlying surface. The article, the bearing arrangement and the shell are configured such that the ball wheel is able to support the article for omni-directional rolling motion over the underlying surface with either of the first and article surfaces parallel thereto, and at any orientation therebetween.
