  • Patent number: 6402234
    Abstract: A bicycle saddle comprises a main body, a supporting frame, and a bracing member. The supporting frame includes two metal bars each having a front section, a midsection and a rear section. The front section is fastened with the underside of a front end of the main body, whereas the rear section is fastened with the underside of a rear end of main body. The two rear sections of the two metal bars of the supporting frame are reinforced by a bracing member for averting lateral movement of the supporting frame at such time when the main body is laterally exerted on by an external force.

  • Patent number: 6343836
    Abstract: A bicycle saddle comprises a main body, two deflection members, a pliable support, and a bracing frame. The main body has a front portion and a rear portion wider than the front portion. The deflection members are fastened pivotally at the top end thereof with two opposite sides of the underside of the rear portion of the main body such that the axial direction of the pivot is corresponding to the front-rear direction of the main body, and that the bottom end of each deflection member swivels. The pliable support is fastened pivotally at both ends thereof with the bottom ends of the deflection members such that the top of the pliable support and the underside of the main body form therebetween a cushioning space. When the pliable support is exerted on by an external force, the pliable support is deformed.

  • Patent number: 6007148
    Abstract: A bicycle saddle is composed of a main body, a support frame, two shock-absorbing devices, and a bridge. The main body has a shape narrowing toward the front end thereof and is provided in the underside of the rear end thereof with two fastening posts. The main body is mounted on the support frame which is formed of two steel bars such that the front ends of the steel bar are joined together and fastened with the front end of the main body. Two steel bars have a hooked rear end. The shock-absorbing devices are fastened with the fastening posts of the main body and the hooked rear ends of the support frame and are composed of a cap, a shock-absorbing pad, and a base. The shock-absorbing pad has one end which is retained in the cap, and another end which is provided with a recess for retaining a conical portion of the base. The hooked rear ends of the support fame are engaged with the bases of the two shock-absorbing devices.

  • Patent number: 5692801
    Abstract: A bicycle saddle includes a saddle body, a front mounting socket member, a pair of spring cantilevers, and a bracket. The saddle body has a front converging portion, a rear diverging portion and a downwardly extending skirt portion. The front mounting socket member is formed at the bottom side of the front converging portion. The spring cantilevers extend from the internal face of the skirt portion toward one another so that a space is formed between the spring cantilevers and the bottom side of the rear diverging portion. Each of the spring cantilevers has an engaging portion formed at the free end thereof. The bracket has a converging bent front end which is inserted into the front mounting socket member and a pair diverging arms. Each of the diverging arms has a free end which engages a respective one of the engaging portions of the spring cantilevers.

  • Patent number: 5558396
    Abstract: The bicycle saddle of a bicycle saddle assembly includes a rigid saddle body which is formed as a looped member and which has a front portion with a nose, an intermediate portion and a rear portion. The saddle body has a width which increases gradually from the nose to the rear portion and defines an opening. The saddle body has a periphery defining the opening which is formed with a plurality of spring retaining holes. The bicycle saddle further includes a rigid spring retaining plate which has a periphery formed with a plurality of spring retaining holes, and a plurality of elongated coil springs, each of which has a first end secured to one of the retaining holes in the saddle body and a second end secured to one of the retaining holes in the retaining plate. The coil springs extend radially in different directions from the retaining plate to the saddle body to enable the bicycle saddle to absorb shock in a plurality of directions when the saddle assembly is in use.

  • Patent number: 5553916
    Abstract: A bicycle saddle includes a saddle body, an opening formed through the saddle body and a plurality of spring-retaining holes formed along the periphery of the opening. The bicycle saddle further includes a spring-retaining assembly and a plurality of elongated coil springs connected between the saddle body and the spring-retaining assembly under tension. The spring-retaining assembly includes at least one first connecting member having a threaded hole. The spring-retaining assembly further has at least one second connecting member which has a counterbore. At least one screw member extends through the counterbore of the second connecting member and engaging the threaded hole of the first connecting member to engage the first and second connecting members. Therefore, the first and second connecting members can be moved with respect to one another by rotating the screw member.

  • Patent number: 5348369
    Abstract: A saddle includes a saddle body, a foam, a covering, and two elastic bodies. The saddle body is made of a hard elastic material and is coated with the foam. The foam is coated with the covering. The saddle body has two accommodating holes formed therethrough and located at two positions in the saddle body under a portion of the covering, on which portion a user normally sits. The elastic bodies are made of a soft elastic material and are retained within the accommodating holes in such a manner that the top ends of the elastic bodies extend from the accommodating holes. Accordingly, the elastic bodies can absorb the shock of two portions of the foam, which two portions are located above the elastic bodies. The saddle body has two retaining units so that the elastic bodies can be retained on the saddle body.
