Abstract
Abstract Apparatus for use by one manipulating a device to be swung such as a golf club, bat or the like. A flexible cord is anchored at one end thereof and has the opposite end affixed to the device to be swung at a point displaced from the grip end thereof. A slide assembly engages the cord between the ends thereof to shorten and lengthen the amount of cord available between the slide assembly and the point of attachment to the swing device as the device is swung by the user. In one embodiment, the cord is threaded through a tubular member disposed to permit additional cord to be pulled therethrough as a swing is executed, while in an additional embodiment, a slider traverses a guide mechanism during the swing and thereby permits additional cord to be presented between the swing device and the slide.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
118 words
Swing training apparatus for perfecting timing of the swing of a device to be swung by a user thereof comprising: a guide means; a slider engaging said guide means for movement therealong; a flexible cord anchored at one end remote from said user and said guide means and attached at its other end to said swing device; means slidably connecting said slider to said cord between the ends thereof to provide varying lengths of said cord between said slider means and said swing device during the swinging thereof with the smallest length of cord between said swing device and said slider at approximately the position in a desired swing of said device where maximum speed thereof is attained.
Claim 2
Dependent Claim
118 words
Swing training apparatus for perfecting timing of the swing of a device to be swung by a user thereof comprising: a guide means; a slider engaging said guide means for movement therealong; a flexible cord anchored at one end remote from said user and said guide means and attached at its other end to said swing device; means slidably connecting said slider to said cord between the ends thereof to provide varying lengths of said cord between said slider means and said swing device during the swinging thereof with the smallest length of cord between said swing device and said slider at approximately the position in a desired swing of said device where maximum speed thereof is attained.
Claim 3
Dependent Claim
39 words
Swing training apparatus as defined in claim 1 wherein said guide means is a hollow tubular member having an elongated slot therethrough and said slider is internally disposed within said guide means with said cord extending through said slot.
Claim 4
Dependent Claim
25 words
Swing training apparatus as defined in claim 1 wherein said guide means is an arcuate member adjustably disposed to accommodate users of varying physical sizes.
Claim 5
Dependent Claim
30 words
Swing training apparatus as defined in claim 3 wherein said arcuate member is supported upon a planar support member and said slider encircles only a portion of said guide means.
Claim 6
Dependent Claim
106 words
Swing training apparatus for perfecting timing of swing of device to be swung by a user thereof comprising: a slider; guide means; means for slidably mounting said slider on said guide means; a flexible cord; means for anchoring one end of said cord remote from said user and said guide means; means for attaching the other end of said cord to said device to be swung at a point displaced from the grip end thereof; means for slidably attaching said cord, intermediate the ends thereof, to said slider, whereby upon the user swinging said device, said slider traverses at least a portion of said guide means.
Claim 7
Dependent Claim
106 words
Swing training apparatus for perfecting timing of swing of device to be swung by a user thereof comprising: a slider; guide means; means for slidably mounting said slider on said guide means; a flexible cord; means for anchoring one end of said cord remote from said user and said guide means; means for attaching the other end of said cord to said device to be swung at a point displaced from the grip end thereof; means for slidably attaching said cord, intermediate the ends thereof, to said slider, whereby upon the user swinging said device, said slider traverses at least a portion of said guide means.
Claim 8
Dependent Claim
16 words
Swing training apparatus as defined in claim 5 wherein said guide means is a continuous member.
Claim 9
Dependent Claim
16 words
Swing training apparatus as defined in claim 5 wherein said slider completely encircles said guide means.
Claim 10
Dependent Claim
35 words
Swing training apparatus as defined in claim 5 wherein said guide means terminates at a point adjacent the position where maximum speed for said device to be swung is developed in a desired swing thereof.
Claim 11
Dependent Claim
33 words
Swing training apparatus as defined in claim 8 wherein said cord is automatically released from said slider upon its reaching the terminus of said guide means thereby allowing said slider to be projected.
Claim 12
Dependent Claim
43 words
Swing training apparatus as defined in claim 5 wherein said guide means comprises an elongated member disposed to include a plurality of convolutions spaced to allow said slider to traverse the entire distance of said guide means without interference from adjacent convolutions thereof.
Claim 13
Dependent Claim
30 words
Swing training apparatus as defined in claim 10 wherein said cord is automatically released from said slider upon its reaching maximum velocity and being adjacent the desired point of impact.
