An abdominal support which includes a pair of shoulder and back straps, each of which passes over one of the wearers shoulders, crosses over the wearer's upper back, and connects to the other shoulder and back strap at the wearer's side; a sling support is secured to each shoulder and back strap at or adjacent the wearers side and a support sling extends from one sling support to the other, passing beneath the wearer's abdomen in use; the sling incorporates length adjusters.

A telescopic support includes a tube and an elongated element inserted in the tube and formed with a series of ratchets. A driving and locking device includes a locking element, a spring and a driving element. The locking element includes a jaw formed with at least one ratchet and being pivotally installed on the tube. The spring is provided between the tube and the locking element for biasing the ratchet of the locking element into engagement with the ratchets of the elongated element. The driv...

A knock-down type support stand especially suited for aquariums or other heavy objects employs double walled support legs that are each formed of inner and outer sleeves of tubing. Upper and a lower horizontal frames act as supports for the objects. Attached to each outside corner of both of the frames is a corresponding one of a plurality of vertical hollow sleeves, each of which is of the same cross sectional dimension as the outer hollow sleeves in the support legs. The inner sleeves for each...

The present invention relates to a collapsible support (1) for absorbing energy during an impact, particularly to a support for an automobile knee bolster (50). The collapsible support (1) has the form of a tubular body with closed ends. The body extends along a longitudinal axis (3) along which it will collapse during an impact. The support (1) has two opposing end walls (4,10) substantially perpendicular to the axis (3). The two end walls (4,10) are connected by four similar stepped side walls...

A bed for a person is provided. The bed includes a deck and/or a mattress having an adjustable length.

A track support for the track of a magnetic levitation railway consists of a steel support having a closed hollow trapezoidal or hollow triangular cross section with closed end faces, whose cover plate projects, in the manner of a jib, with its longitudinal edge sections over the side wall web plates, and at the end of which cover plate a side guidance rail is arranged in each case. In order to keep the surfaces of the track support that are exposed to environmental influences as small as possib...

A back portion (16) for a chair (10) includes a peripheral frame (34) defining an opening therein. A lumbar support portion (36) is disposed in the opening. The lumbar support portion (36) comprises a substantially rigid panel (207). Two hinge devices (214) are hingedly mounted on opposite sides of the peripheral frame (34). The lumbar support portion (207) is mounted on the peripheral frame by the two hinge devices (214). Each hinge device has a biasing device (226) associated with it to bias t...

A turbine engine has a rotor shaft rotatably carried within a non-rotating support structure. A seal is carried by the support structure circumscribing the shaft and having a flexible sealing element for sealing with the shaft. A chamber is located between the seal and support structure. A fluid is carried within the chamber and damps radial excursion of a seal axis from a support structure axis. The seal may be a full annulus or may be segmented. The fluid may be contained within one or more el...

In a fixture for supporting a workpiece in a machine tool by means of two support elements held in a housing with the workpiece lying on them, the support elements are configured as levers held in a rotating mounting in the housing, the levers being driveably connected together by means of a threaded spindle. The threaded spindle has counter-rotating thread sections in areas corresponding to the support elements, and each of the counter-rotating thread sections of the spindle engage in a sliding...

A bipod type gun support has a generally cylindrical hub that defines a barrel-receiving bore that can be slipped onto and off of the muzzle end of the gun. Downwardly diverging legs are integrally joined to opposite sides of the hub to present a one-piece construction. A slot along the top of the hub facilitates a slight amount of resilient flexing of sidewall portions of the hub toward and away from one another when the diverging legs are squeezed and released, thus enlarging the bore of the h...
