摘要:
A turntable for vertical support of substantially horizontal loaded surfaces, which has an upper and a lower half, between that it includes a vertical rotatable guiding element. A braking element (6) is located within the guiding element (3), which limits the vertical downward movement of the horizontal surface to a given speed, and the guiding element (3) includes a threaded part (4) that changes the vertical downward movement to rotating motion. The upper half (1) during its downward movement is connected to the lower half (2) by a mechanical coupling for rotation transfer by engagement into the threaded part (4). The braking element (6) is allowing backward movement of the upper half (1) relatively to the lower half (2) substantially without braking after expiry of the loading. The upper half (2) during its upward movement is connected to the lower half (2) without mechanical coupling for rotation transfer.
摘要:
A water heater arrangement comprising a gas-operated water heater device (1) that has an cold water inlet pipeline (2) and an hot water outlet pipeline (3), and which further comprises a storage type electric water heater (4) inserted serially into the hot water outlet pipeline (3), and which is equipped with a thermostat (5). In an embodiment it absorbs and utilizes the waste heat of the gas-operated water heater device (1).
摘要:
The pushbutton mechanism comprises a lower part (1) and a cover (2) which are connected to each other and together constitute a house; a push bar (3) being in contact with the cover (2) and passing through an opening (5) in the lower part (1) and protruding out from that; an activation surface being on the cover (2); a biasing spring (4) between the cover (2) and the lower part (1) providing mechanic bias at the initial position of the pushbutton mechanism; and the cover (2) is able to move from its initial position when approaching relatively to the lower part (1) in response to an external pressing force. The cover (2) is formed as a single piece and is attached to the lower part (1) so that it is movable to an angled position compared to its initial position, the angled position of the cover (2) and thus that part of the displaced push bar (3) protruding out of the lower part (1) is depending on the point of exertion the pressing force within the activation surface.
