Abstract: The present disclosure relates to a shock absorbing arrangement suitable e.g. for ship installed structures comprising a rod, a resilient member arranged in connection to the rod, a structure element and a locking member arranged in connection to the structure element. The locking member is arranged to detachably lock the structure element at a resting position at the rod and the locking member, or the structure element, is supported by the resilient member. The resilient member is configured such that a spring force of the resilient member acts to maintain the structure element essentially at the resting position at the rod. The locking member is further configured to release the structure element from the resting position when being exposed to a force exceeding a predetermined holding force, whereupon the resilient member acts to reinstate the locking of the structure element at the resting position at the rod.

Abstract: A spring is continuously acting on an upper part adjustable in the height by a spindle for compensating the weight of the vertical adjustable parts. An additional compensating spring acts over a piston on the upper part.

Many compensating springs can be provided which, at choice, can be rendered effective or ineffective in order to compensate for different weights.

Abstract: An essentially tubular spring housing (FIGS. 5, 6) is formed with longitudinal slits (8d, 8e) into which the support spring blocking structure (1, 10) can be assembled. The support spring blocking structure, in one form (FIGS. 1, 2) is a longitudinal rail retaining a plurality of stacked blocking plates (2) therein, between abutments (3, 4) which are spaced wider than the length of the stack of plates (2) to permit engagement of a spring plate (7) between selected blocking plates, and thus lock the spring plate, and hence the spring, in selected position. In another embodiment (FIGS. 3, 4), the stacked plates (9) are slidable in a holder band or strip (10a). The holders (1a, 10a) are formed with a longitudinal, externally projecting holding hook (5, 11) to permit storing the blocking structure on the spring holder (right side, FIGS. 5, 6) in readily accessible position.

Abstract: In a mechanism or support for a television or movie camera which allows the camera to be tilted or pitched upwardly and downwardly, the weight of torque offered by the camera is counterbalanced by means of a series of accumulators or spring elements placed between the rotatable support for the camera and the stator portion of the support and adapted to be selectively engaged between the rotor and stator, depending upon the weight of the camera being used. Preferably each accumulator offers a restoring torque that is different from that of the other accumulators such that by selective engagement of various combinations of accumulators many different weights of cameras can be accommodated.

Abstract: Delicate equipment is mounted on a carrier such as a vessel or a vehicle by means of shock absorbers which are spring biased to an accurately defined position in which the equipment is rigidly fastened to the carrier. When the carrier is subjected to a shock force exceeding the biasing of the shock absorbers, the rigid connection is released and the equipment thus protected against damaging forces.Each shock absorber has a single compression spring which is compressed by an axial force on the shock absorber regardless of the direction of the force.At least three parallel, vertical shock absorbers carry the equipment. Horizontal shocks are absorbed due to the tilting movement of the equipment relative to the shock absorbers, which are thus subjected to vertical movements in opposite directions.

Abstract: In a seat suspension wherein a seat part is slidable fore-and-aft on a suspension part, a latching member having an elongated slot therein is swingable to and from a normal position about a rivet secured to the seat part and extending through the slot. In its normal position, the latching member engages the suspension part to be locked against fore-and-aft motion, but the seat part can move fore-and-aft between slot-defined limits. A control member is pivoted to the latching member on an axis spaced from and parallel to that of said rivet, which extends through a triangular cutout in the control member. The control member has one limit position wherein a portion of said cutout registers with said slot for fore-and-aft shock isolating motion of the seat part and an intermediate position wherein an apex portion of the cutout engages the rivet to prevent seat part motion.

Abstract: A spring loaded vehicle seat is of the kind having a seat frame and an underframe supports this seat frame by levers and a pneumatic spring so that the seat is maintained at a constant height. Valves control the flow of air to and from the spring to counteract the effect of vibrations. A switch mechanism controls the operation of the valves and a coupling device transmits vibrations of the seat to the mechanism. The coupling device is arranged so that movement of the mechanism after opening a valve lags behind the vibration of the seat.
