A support device has a planar base that is positioned under the legs of a user and on top of the surface of the chair, when a user is in a seated position. An adjustable tube connects the base to an adjustable joint, with a platform on the opposing side of the adjustable joint. The adjustable joint provides position adjustments to the platform in the orientations of pitch, roll, and yaw. The adjustable tube allows the distance from the base to the platform to change. The device supports the weight of an instrument which may be placed on the platform.

The helmet unit is configured to fix an object thereon. The ball unit is configured to adjust orientation of the helmet unit. The yoke unit is configured to adjust position of the plurality of leg units. And the plurality of the leg units is configured to adjust orientation thereof respectively.

The invention relates to a method for displacing a ceiling formwork (10) for a nearest concreting section (9), wherein first (11) and second (12) supporting devices for supporting the ceiling formwork (10) are arranged below the nearest concreting section (9). Said supporting devices each have a shuttering position (EP) and a stripping position (AP), wherein the ceiling formwork is raised to a concreting level in the shuttering position (EP) and lowered relative to the concreting level in the stripping position (AP). The first supporting device (11) is moved into the stripping position and the second supporting device is moved into the shuttering position, and a collision protection element (15, 15) is arranged between the second supporting device (12) and an end face (17, 17) of the ceiling formwork (10) when the end face (17, 17) of the ceiling formwork (10) strikes the second supporting device (12) after passing over the first supporting device (11), so that the collision protection element (15, 15) forms a flank (15a) rising in the displacement direction (VR) for guiding the ceiling formwork (10) in the displacement direction (VR). The end face (17, 17) of the ceiling formwork (10) is then liftedguided by the collision protection element (15, 15)to the concreting level so that the ceiling formwork (10) passes over the second supporting device (12).

The invention relates to a supporting device (14, 14, 14, 15, 15, 15) for the construction industry. Said device has a fixing element (14a, 15a) which rests against a side wall (2a) and is fixed at a fixing point (FP) of the side wall (2a). Said device also has a cantilever (14b1, 14b2, 14c; 15b1, 15b2, 15c-15e) which is connected to the fixing element (14a, 15a) and, when the fixing element (14a, 15a) is in the fixed state, projects from the side wall (2a) such that a load element (10) can rest against a bearing point (AP) of a bearing element (14b1, 14b2; 15b1, 15b2) of the cantilever. The load element (10) can now be displaced in a displacement direction (VR) substantially parallel to the side wall (2a) relative to the cantilever and, when the load element (10) rests against the bearing element of the cantilever, the cantilever is coupled to the load element (10) such that a displacement force component acts on the cantilever in the displacement direction (VR) when the load element (10) is displaced, said displacement force component resulting in a torque on the cantilever. The device also comprises an anti-rotation element (16, 16, 17, 17) which is connected to the cantilever. When the load element (10) is displaced, another end of the anti-rotation element should rest against the side wall (2a) in order to counteract the torque.

An electric lifting frame includes a lifting pedestal and a remote control. The lifting pedestal includes a supporting base, a lifting rod detachably connected to the supporting base, and a transmission mechanism, a motor, a controller, and a power supply provided at the lifting rod. The motor is configured to effect extension and retraction of the lifting rod via the transmission mechanism. The controller is configured to control starting and stopping and a rotation direction of the motor. The power supply is configured to supply electric energy to the motor and the controller. The controller is further configured to determine a remaining capacity of the power supply and calculate a number of remaining available times of use according to the remaining capacity, a power of the motor, and a stroke of the transmission mechanism.

A pedestal is provided having a telescoping column and an integrated master/slave actuator unit for a telescoping column of a pedestal-mounted support structure such as a surgical bucket, storage container, receptacle, utility tray, work surface, seat, equipment or automotive service rack, or other platform. The telescoping column preferably is vertically extendible and retractable by an actuator unit, which preferably is manually-actuated such as by being foot-actuated and vertically extendable to raise and lower the platform. The actuator unit is operated by an actuator pedal or other drive unit through an actuator stroke, which causes the column to raise and lower through a lift stroke. The actuator stroke is smaller than the lift stroke so that a small movement, such as by downward movement of the user's foot, allows the column to rise through an extended distance, i.e. the lift stroke. The actuator pedal may be actuated again, such as by being depressed downwardly, to unlock the column and allow the column to automatically retract preferably in response to the weight of the pedestal and gravity acting thereon.
