Abstract
Abstract There is disclosed a holder device for mounting a forceresponsive transducer of the type sensing transverse or bending stresses. The holder device comprises a stationary member and a movable member for applying a force in a selected measuring direction to the movable member. Connecting members join the movable member to the stationary member and are positioned to act as a mild restraining force in the selected measuring direction. The stationary member and the movable member each include a recess for receiving therein an actuating part and a mounting part respectively of the transducer to be mounted on the holder device. The recesses are so located that a neutral axis of the transducer supported in the recesses is substantially parallel to lengthwise and transverse directions of the connecting members. The measuring direction is substantially normal to the neutral axis whereby a load applied to the movable member causes tensioning of each of the connecting members.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
215 words
A device for mounting a force-responsive transducer of the bending-stressed beam type for sensing transverse or bending stresses, said device comprising in combination: a rigid stationary support member, a rigid movable member responding to a force in a selected measuring direction said movable member being disposed within said stationary member, a pair of yielding connecting members for joining the movable member to the stationary member, said connecting members being positioned to act as a restraining force in said selected measuring direction, said stationary member having first extensions and said movable member having second extensions, said extensions being disposed in substantially juxtaposed and spaced apart relationship, said connecting members joining the extensions of the stationary member to the extensions of the movable member, a force-responsive transducer having a bendingstressed beam including an actuating part and a mounting part, said stationary member and said movable member further each including a recess for receiving therein said force-responsive transducer, the locations and configurations of said recesses being such that a neutral axis of the transducer received in said recesses is substantially parallel to lengthwise and transverse directions respectively of said connecting members and that said measuring direction is substantially normal to said neutral axis whereby a load on the movable member causes tensioning of each of said connecting members.
Claim 2
Independent Claim
215 words
A device for mounting a force-responsive transducer of the bending-stressed beam type for sensing transverse or bending stresses, said device comprising in combination: a rigid stationary support member, a rigid movable member responding to a force in a selected measuring direction said movable member being disposed within said stationary member, a pair of yielding connecting members for joining the movable member to the stationary member, said connecting members being positioned to act as a restraining force in said selected measuring direction, said stationary member having first extensions and said movable member having second extensions, said extensions being disposed in substantially juxtaposed and spaced apart relationship, said connecting members joining the extensions of the stationary member to the extensions of the movable member, a force-responsive transducer having a bendingstressed beam including an actuating part and a mounting part, said stationary member and said movable member further each including a recess for receiving therein said force-responsive transducer, the locations and configurations of said recesses being such that a neutral axis of the transducer received in said recesses is substantially parallel to lengthwise and transverse directions respectively of said connecting members and that said measuring direction is substantially normal to said neutral axis whereby a load on the movable member causes tensioning of each of said connecting members.
Claim 3
Dependent Claim
26 words
The device according to claim 1 wherein each of said first extensions on the stationary member protrudes past the respective second extension on the movable member.
Claim 4
Dependent Claim
36 words
The device according to claim 1 wherein said recesses in the stationary member and the movable member each have a cylindrical configuration for receiving therein a correspondingly shaped actuating part and mounting part of a transducer.
Claim 5
Independent Claim
280 words
A device for mounting a force-responsive transducer of the bending-stressed beam type for sensing transverse or bending stresses, said device comprising in combination: a rigid stationary support member, a rigid movable member for responding to a force in a selected measuring direction, said movable member being disposed within said stationary member, a pair of yielding connecting members for joining the movable member to the stationary member, said connecting members being yieldable in the selected measuring direction but acting as restraining force in said direction, said stationary member having first extensions and said movable member having second extensions, said extensions being disposed in substantially juxtaposed and spaced apart relationship, said connecting members joining the extensions of the stationary member to the extenSions of the movable member, a force-responsive transducer having a bending-stressed beam including an actuating part and a mounting part, said stationary member and said movable member further each including a recess for receiving therein said force-responsive transducer, a force transmitting member interposed between the movable member and the actuating part of the transducer, said force transmitting member coacting with an adjacent surface in said recess of the movable member in response to a deformation of said connecting members due to a response of the movable member to a load, thereby causing actuation of the actuating part of the transducer, the locations and configurations of said recesses being such that a neutral axis of the transducer received in said recesses is substantially parallel to lengthwise and transverse directions respectively of said connecting members and that said measuring direction is substantially normal to said neutral axis whereby a load on the movable member causes tensioning of each of said connecting members.
Claim 6
Independent Claim
280 words
A device for mounting a force-responsive transducer of the bending-stressed beam type for sensing transverse or bending stresses, said device comprising in combination: a rigid stationary support member, a rigid movable member for responding to a force in a selected measuring direction, said movable member being disposed within said stationary member, a pair of yielding connecting members for joining the movable member to the stationary member, said connecting members being yieldable in the selected measuring direction but acting as restraining force in said direction, said stationary member having first extensions and said movable member having second extensions, said extensions being disposed in substantially juxtaposed and spaced apart relationship, said connecting members joining the extensions of the stationary member to the extenSions of the movable member, a force-responsive transducer having a bending-stressed beam including an actuating part and a mounting part, said stationary member and said movable member further each including a recess for receiving therein said force-responsive transducer, a force transmitting member interposed between the movable member and the actuating part of the transducer, said force transmitting member coacting with an adjacent surface in said recess of the movable member in response to a deformation of said connecting members due to a response of the movable member to a load, thereby causing actuation of the actuating part of the transducer, the locations and configurations of said recesses being such that a neutral axis of the transducer received in said recesses is substantially parallel to lengthwise and transverse directions respectively of said connecting members and that said measuring direction is substantially normal to said neutral axis whereby a load on the movable member causes tensioning of each of said connecting members.
Claim 7
Dependent Claim
36 words
The device according to claim 4 wherein said fixed member, said movable member and said connecting members are a one-piece body including elongate slots extending parallel to and crosswise of the neutral axis of said body.
Claim 8
Dependent Claim
