Abstract
Abstract An acceleration responsive device 30 includes a support 34 which supports a rod 46 between two spaced portions of the support. A weighted disc 48 is mounted for movement on the rod and is held by a spring 128 at one end of the rod 46. An indicator 50 is also mounted for movement on the rod 46 adjacent disc 48. A tube 62 is coupled to support 34 to facilitate swinging movement of the device 30 where, due to the acceleration thereof, disc 48 is moved along rod 46 and pushes indicator 50 along the rod. When the swinging movement ceases, disc 48 is returned to the one end of rod 46 and indicator 50 remains at the position to which it was moved. A scale reading of a decal 89 adjacent the moved indicator 50 provides a indication of the acceleration attained during the swinging of device 30. This reading can be applied to a graph to assist the user of device 30 in the selection of golf clubs having a shaft stiffness most appropriate for the user.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
276 words
An acceleration responsive device, which comprises: a support, a handle attached to the support, a track located on the support extending between at least a first portion to a second portion of the support and located at an angle with respect to the handle, a first member located on the track in a normal position at a prescribed location of the track adjacent the first portion of the support and having a first side which faces toward the second portion of the support and a second side which faces away from the second portion of the support, a second member located on the track in a normal position adjacent the first member and having a face which interfaces with the second side of the first member, each of the first and second members being located on the track for movement relative thereto, a biasing element attached to the second member for allowing the second member to move along the track and to biasingly return to the normal position thereof, whereby, upon movement of the support in a prescribed manner, and due to the acceleration applied thereto, the second member is caused to move along the track toward the second portion of the support against the biasing action of the biasing element to push the first member toward the second portion of the support where, after reaching the maximum acceleration during the movement, the second member returns under the action of the biasing element to the normal position of the second member and the first member remains at its moved position on the track as an indication of the acceleration of the support during the movement thereof.
Claim 2
Dependent Claim
276 words
An acceleration responsive device, which comprises: a support, a handle attached to the support, a track located on the support extending between at least a first portion to a second portion of the support and located at an angle with respect to the handle, a first member located on the track in a normal position at a prescribed location of the track adjacent the first portion of the support and having a first side which faces toward the second portion of the support and a second side which faces away from the second portion of the support, a second member located on the track in a normal position adjacent the first member and having a face which interfaces with the second side of the first member, each of the first and second members being located on the track for movement relative thereto, a biasing element attached to the second member for allowing the second member to move along the track and to biasingly return to the normal position thereof, whereby, upon movement of the support in a prescribed manner, and due to the acceleration applied thereto, the second member is caused to move along the track toward the second portion of the support against the biasing action of the biasing element to push the first member toward the second portion of the support where, after reaching the maximum acceleration during the movement, the second member returns under the action of the biasing element to the normal position of the second member and the first member remains at its moved position on the track as an indication of the acceleration of the support during the movement thereof.
Claim 3
Dependent Claim
141 words
An acceleration responsive device, which comprises: a support, a handle attached to the support, a track formed in the support and extending from a first portion of the support to a spaced second portion thereof and located at an angle with respect to the handle, an acceleration responsive element located at a first end of the track in a rest position and mounted for movement on the track, a movable element located on the track in a rest position adjacent the acceleration responsive element and between the acceleration responsive element and a second end of the track spaced from the first end thereof, the movable element mounted on the track for movement relative thereto, and a biasing element coupled between the support and the acceleration responsive element to normally urge the acceleration responsive element toward the first end of the track.
Claim 4
Dependent Claim
141 words
An acceleration responsive device, which comprises: a support, a handle attached to the support, a track formed in the support and extending from a first portion of the support to a spaced second portion thereof and located at an angle with respect to the handle, an acceleration responsive element located at a first end of the track in a rest position and mounted for movement on the track, a movable element located on the track in a rest position adjacent the acceleration responsive element and between the acceleration responsive element and a second end of the track spaced from the first end thereof, the movable element mounted on the track for movement relative thereto, and a biasing element coupled between the support and the acceleration responsive element to normally urge the acceleration responsive element toward the first end of the track.
Claim 5
Dependent Claim
32 words
The acceleration responsive device as set forth in claim 2, wherein the support includes a body of a prescribed configuration, a housing section and a cover for attachment to the housing section.
Claim 6
Dependent Claim
49 words
The acceleration responsive device as set forth in claim 2, wherein the support includes a body having an elongated slot formed therethrough, and a rod mounted in and extending from one end of the elongated slot to an opposite end thereof, whereby the slot and rod form the track.
Claim 7
Dependent Claim
36 words
The acceleration responsive device as set forth in claim 2, wherein the acceleration responsive element is of a prescribed shape formed with a pair of slots extending outwardly to and through a periphery of the element.
Claim 8
Dependent Claim
17 words
The acceleration responsive device as set forth in claim 2, wherein the biasing member is a spring.
Claim 9
Dependent Claim
25 words
The acceleration responsive device as set forth in claim 2, which further comprises at least one weight of a prescribed weight attached to the support.
Claim 10
Dependent Claim
41 words
The acceleration responsive device as set forth in claim 2, which further comprises a scale of characters appearing on the support adjacent the track to provide an indication of the location of the movable element following accelerating movement of the support.
Claim 11
Dependent Claim
39 words
The acceleration responsive device as set forth in claim 2, which further comprises a tube coupled to the support to provide the handle for the device and facilitate swinging movement of the support by a user of the device.
Claim 12
Dependent Claim
35 words
The acceleration responsive device as set forth in claim 4, wherein the elongated slot is defined by spaced opposed edges of the body extending between the first portion and the second portion of the support.
Claim 13
Dependent Claim
