A spring assembly includes coil springs supported on a spring support member. The coil springs include plural first coil springs and a second coil spring. The spring support member includes a first support member and a second support member facing the first support member. One ends of the first coil springs are supported on a front surface of the first support member. One end of the second coil spring is supported on the front surface of the first support member or a front surface of the second support member, and in this state, another end of the second coil spring protrudes further than other ends of the first coil springs. A sum of elastic repulsive forces of the first coil springs is larger than an elastic repulsive force of the second coil spring in a state where the first coil springs and the second coil spring are compressed.

The present invention relates to a compression spring assembly for a hay rake. The compression spring assembly has a rod that slidably receives a first stop, a compression spring, and a second stop. A limiter assembly is connected to the rod and has a limiting member that is received through a guide of a guide assembly that is connected to the rod. The guide encompasses the limiting member.

A bumper spring assembly having a one piece mandrel including an integral head piece is further configured with a cage assembly retained on the mandrel with a cage nut locked to the mandrel to obviate the need for pins, set screws, and the like, to provide a more robust assembly. In two embodiments the cage nut is locked to the mandrel in a swaging operation. Improved flow of fluids through and around the bumper spring assembly are also provided

Disclosed herein are shock absorbing foot pieces configured to be attached to an apparatus and to absorb the weight of the attached apparatus and any impact caused by the normal usage of the apparatus. In one or more embodiments, the shock absorbing foot pieces comprise multiple elements including a biasing spring and that are configured as a unitary piece.

A flexure is disclosed for accommodating misalignments in an assembly. The flexure can include a first portion, a second portion, and a flexible portion coupling the first portion and the second portion to one another. The flexible portion can facilitate relative movement between the first and second portions in a plurality of degrees of freedom. The flexure can further include one or more stops operable to limit relative movement between the first and second portions in at least two of the plurality of degrees of freedom.

A spring apparatus (10), including: a spring (12); an elongated object (18A) disposed within and along the spring (12); and a mode-changing assembly (16), for providing a first mode in which a portion (38) of the spring (12) being along the elongated object (18A) is not springy, and a second mode in which an entire of the spring (12) is springy.

An load adaptive lift assist for a pivoting stowage bin includes an assembly housing having an interior and a pair of opposing end fittings. A piston rod is disposed within the assembly housing and operatively coupled to one of the end fittings, the piston rod being configured to move between extended and retracted positions based on the movement of the pivoting stowage bin. A spring retainer is attached to a structure that retains at least one lift assist spring and a latch mechanism is operatively coupled to the other of the end fittings. The latch mechanism includes at least one mechanical feature for retaining the spring retainer until a predetermined load has been exceeded in the stowage bin. The load adaptive lift assist automatically resets itself and does not require use of sensors or feedback controls.

This coupling device comprises a support body, a first clamping jaw, a clamping member comprising a second clamping jaw and a connecting portion, the clamping member being hingedly mounted on the support body between a clamping position in which the first and second clamping jaws are configured to clamp a traction cable; a biasing device configured to bias the clamping member towards the clamping position, and an actuation member configured to actuate a displacement of the clamping member between its clamping and release positions, the actuation member being slidably mounted on the support body between a first stable position in which the clamping member is in the clamping position, and a second stable position in which the clamping member is in the release position.

A bellows assembly for a vibration damper includes a bellows with a plurality of pockets with pocket walls and a pocket inner profile, a helical compression spring with windings consisting of a wound spring wire and pressure contact lateral faces. The helical compression spring is arranged in the bellows and the plurality of pockets extend coaxially to the longitudinal axis of the helical compression spring. Under pressure loading of the helical compression spring arranged in the bellows, the bellows folds together with the helical compression spring, wherein the wound spring wire is arranged at least in certain portions in the plurality of pockets, wherein the pocket walls of the plurality of pockets in which the wound spring wire is arranged at least in certain portions cover at least the mutually opposite pressure contact lateral faces of adjacent windings of the helical compression spring.

A child stroller includes a frame member and a wheel attachment member including a first end and a second end. A wheel is coupled to the first end, with the second end coupled to the frame member. The stroller further includes a shock absorber having a body, an upper end coupled to the frame member, a lower end coupled to the wheel attachment member, and a spring mechanism disposed within the body. The spring mechanism includes an upper portion exhibiting a first spring constant, and a lower portion exhibiting a second spring constant different from the first spring constant.
