  • Patent number: 7624958
    Abstract: The invention relates to a fastening block for mounting objects on a profiled rail (12) having an at least approximately rectangular cross-section. The fastening block comprises a housing part (14) with at least one claw (26), which is fixed to the housing and reaches over the profiled rail (12) so that the housing part (14) rests against two faces of the profiled rail (12) via contact surfaces that are parallel to the profiled rail (12). The fastening block also comprises an L-shaped moving clamping part (28) which, with its first L-limb (30), is mounted on the housing part (14) in a manner that permits it to pivot about a first axis (32) that is parallel to the contact surfaces and which is pretensioned into a clamping position in which it reaches around the profiled rail (12) with its second L-limb (34) provided in the form of a claw. Lastly, the fastening block comprises a tightening device (40, 46, 72) for tightening and blocking the clamping part (28) in the clamping position.

  • Patent number: 5083331
    Abstract: A mobile patient support system includes a table plate, a support column for supporting the table plate and a transport carriage for transporting the table plate. Two pin-shaped connecting elements arranged on the table plate are receivable in complementary pin receivers of the support column for connection therewith. The table plate is transferrable by relative motion between the transport carriage and the support column from the support column to the transport carriage and the reverse. The table plate and the support column on one hand are provided with latching means and the table plate and the support column on the other hand are likewise supplied with latching means for exchangeable engagement with one another. On each connecting element are at least two latching members supported for movement between a latching position and a free position, and during the transfer process they are simultaneously insertable in a pin receiver of the column and a pin receiver of the transfer carriage.
