An apparatus may include an enclosure that includes a plurality of mounting features that are configured to receive information handling systems, a plurality of casters coupled to the enclosure, and first and second dampers. The first damper may have a first resonance frequency and be disposed such that, when the information handling systems are received in the enclosure, the first damper is coupled between the information handling systems and the plurality of casters. The second damper may have a second, different resonance frequency and be disposed such that, when the information handling systems are received in the enclosure, the second damper is coupled between the information handling systems and the plurality of casters.

A luggage article may include a plurality of walls together defining an outer structure of the luggage article, a wheel bracket attached to and extending from one of the walls, and one or more wheels attached to the wheel bracket. The wheel bracket may comprise a leaf spring having a loop-shaped profile and the one or more wheels may be rotationally attached to a lower end of the loop-shaped leaf spring. The configuration of the wheel bracket may result in higher shock absorption and reduced wheel noise comparative to conventional wheel brackets, and offer an improvement and alternative to conventional luggage wheel brackets.

A castor suspension system for suspending a first castor at a patient support device is provided. The castor suspension system comprises a pivoting suspension link pivotably attachable to the patient support device, and a springy element comprising a leaf spring made of a band deformed such that the band makes at least one U-turn so that the band has a first leg and at least one second leg. One of the first leg and the at least one second leg is provided with a first support portion supported on the pivoting suspension link, and the other of the first leg and the at least one second leg is provided with a second support portion for supporting the springy element with respect to the patient support device such that the springy element is configured to provide a pre-stress force to the pivoting suspension link.

A mobile X-ray imaging apparatus includes a main body performing X-ray imaging by operating an X-ray source, a movable wheel provided in a lower end of the main body and capable of moving the main body, and a support portion comprising a wheel support plate supporting the movable wheel capable of rotating, a frame connected to the main body and supporting the wheel support plate capable of moving, an elastic member disposed between the frame and the wheel support plate and applying an elastic force to the wheel support plate in a direction in which the movable wheel faces a ground, and a stopper restricting a movement of the wheel support plate, wherein the elastic force of the elastic member is smaller than a minimum load applied to the movable wheel.

A front suspension wheel for mobile robotic devices that can be compressed into or decompressed out of a main body of a mobile robotic device to facilitate driving the mobile robotic device over obstacles, thresholds and the like. The wheel will provide the mobile robotic device with information such as how fast the wheel is traveling. The wheel is easily removable by hand by the user.

A caster wheel suspension assembly for a wheelchair or the like includes a housing with a clevis portion and a tubular portion; a fork member pivotably mounted in the clevis portion of the housing, the fork member having a pair of fork arms extending from the housing, each of the fork arms terminating in a lower end, the fork member having an upper portion formed as a clevis tang disposed in the clevis portion of the housing; a damping element in the tubular portion of the housing; and a compression adjustment element connected to the clevis pin and extending axially through the damping element. The compression adjustment element is configured to apply an adjustable compressive force to the damping element, and it is further configured to be moved axially within the tubular portion of the housing for adjustment of the compressive force applied to the damping element.

A shock absorber wheel system for absorbing vibrations and impacts on precision transport and the translocation vehicles like patient stretchers, new born baby units, portable medical devices in the health sector has a track wheel, a compressive spiral spring absorbing the vibrations and the impacts, an upper spring holder which is connected to the spiral spring and has a spindle at one end and a centering housing at the other end, a lower spring holder which is connected to the spiral spring and has a housing providing connection to the track wheel at one end and has a centering spindle connected to said centering housing.

A caster may include a shaft, a first elastic ring, a C-shaped ring, and a second elastic ring. The shaft has one end inserted and secured in a wheel, and a first rod is extended from the other end of the shaft, and a second rod protrudes from an end of the first rod. The diameter of the first rod is larger than that of the second rod, and an end of the second rod comprises a flexible portion. The shaft only needs to be processed to form the second rod and the flexible portion, and the first elastic ring and the second elastic ring which are identical are adapted to be formed through the same mold so as to save the manufacturing cost.
