  • Patent number: 10104956
    Abstract: A connecting device for connecting a table leg to a table leaf having a back-gripping element, which can be disposed on the table leaf and has an engagement hole and a locking device, which can be disposed on the table leg. The locking device has a clamping element having an engagement hook which is designed to engage the engagement hole of the back-gripping element, a spring element, which is supported at least indirectly against the clamping element and at least indirectly against a spring abutment, and an actuating element. The actuating element acts on the spring abutment so that, in a locking position, the spring abutment applies sufficient force to secure the engagement hook of the clamping element in the engagement hole, and in an unlocking position, the spring abutment is in a position in which the spring element is at least partially unloaded in relation to the locking position.

  • Patent number: 10001010
    Abstract: A hydrostatic axial piston machine (1) utilizing a bent-axis construction has a driveshaft (4) with a drive flange (3) rotatable around an axis of rotation (Rt) inside a housing (2). A cylinder barrel (7) has pistons (10) fastened in an articulated manner to the drive flange (3). The drive flange (3) is supported on a housing-side slide face (101) by an axial bearing (100) in the form of a hydrostatically relieved sliding bearing (102) having a plurality of slippers (105). Each of the slippers (105) is mounted in an articulated manner in the drive flange (3) so that when the drive flange (3) rotates, a compensating force (FFR) acts on the slipper (105) which is in the opposite direction to the centrifugal force (FF) acting on the slipper (105). The point of application (AP) of the compensating force (FFR) on the slipper (105) is selected so that there is no tipping moment on the slipper (105) or to compensate for some or all of any tipping moment that does occur.
