Abstract
Abstract A machine for training football players and wrestlers comprises a rigid U-shaped support frame (12a, 12b, 14) which supports vertical struts (22a, 22b). A crossbeam carrying a dummy (39) slides either in vertical guides (24a, 24b) or in inclined guides (26a, 26b) which have switchable cams. These cams are joined to both guides so that one of them is open when the other is closed. The upper ends of the guides have measuring device for registration of forces applied by the athlete to the dummy. By opening or closing respective guides, it is possible to use the machine for various moves, thereby developing in the athlete rapid dynamic reflexes.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
An apparatus for physical training, comprising: a supporting frame; vertical guide means supported by said frame; at least one inclined guide means merging with said vertical guide means; a horizontal crossbeam element positioned for movement in said vertical and said inclined guide means; means for selectively guiding said horizontal crossbeam into either of said horizontal or said inclined guide means; a dummy attached to and capable of rotating about said horizontal crossbeam element; loading means attached to said crossbeam element for adding weight to said dummy.
Claim 2
Independent Claim
86 words
An apparatus for physical training, comprising: a supporting frame; vertical guide means supported by said frame; at least one inclined guide means merging with said vertical guide means; a horizontal crossbeam element positioned for movement in said vertical and said inclined guide means; means for selectively guiding said horizontal crossbeam into either of said horizontal or said inclined guide means; a dummy attached to and capable of rotating about said horizontal crossbeam element; loading means attached to said crossbeam element for adding weight to said dummy.
Claim 3
Dependent Claim
64 words
The apparatus of claim 1 wherein said frame comprises a U-shaped supporting element and vertical struts are attached to the legs of said U-shaped supporting element, said vertical and inclined guides being formed in said vertical struts, said inclined guides being branched upwardly and rearwardly from said vertical guides so that said crossbeam element can freely enter said inclined guide from said vertical guide.
Claim 4
Dependent Claim
35 words
The apparatus of claim 2 wherein said selective guide means includes means for selectively closing either (a) the part of said vertical guide which is located above said inclined guide, or (b) said inclined part.
Claim 5
Dependent Claim
37 words
The apparatus of claim 2, further including lower supporting means adjustably located in said vertical guide and upper indicating means at upper ends of said vertical and inclined guides for indicating the force applied to said dummy.
Claim 6
Dependent Claim
20 words
The apparatus of claim 4 wherein said lower supporting means support means comprises resilient means which supports said crossbeam element.
Claim 7
Dependent Claim
27 words
The apparatus of claim 2 wherein said inclined guide means is positioned at an angle within the range of 15° to 85° to said vertical guide means.
Claim 8
Dependent Claim
41 words
The apparatus of claim 1 wherein said dummy is shaped like a human being and consists of an upper part rotatable about said horizontal crossbeam element and a lower part rotatable on a vertical axis with respect to said upper part.
Claim 9
Dependent Claim
31 words
The apparatus of claim 1 wherein the ends of said crossbeam element extend outwardly beyond said frame and said loading means comprises a set of disks fitted on said extending ends.
Claim 10
Dependent Claim
155 words
An appartus for training football players and wrestlers comprising: a support frame; a pair of stationary vertical columns rigidly atttached to said support frame and having vertical guides; a pair of struts telescopically inserted into said vertical guides and having means for locking said struts in said vertical guides; each of said struts having vertical guide means; a pair of inclined guide means extending rearwardly and upwardly from said vertical guide means; a horizontal crossbeam guided to move in said vertical and said inclined guide means; means for selectively opening said inclined guide means and closing the part of said vertical guide means located above its point of merging with said inclined guide means, or for closing said inclined guide means and opening said part of said vertical guide means; a dummy capable of rotating about said horizontal crossbeam element; and loading means attached to said horizontal crossbeam element for adding weight to said dummy.
Claim 11
Dependent Claim
155 words
An appartus for training football players and wrestlers comprising: a support frame; a pair of stationary vertical columns rigidly atttached to said support frame and having vertical guides; a pair of struts telescopically inserted into said vertical guides and having means for locking said struts in said vertical guides; each of said struts having vertical guide means; a pair of inclined guide means extending rearwardly and upwardly from said vertical guide means; a horizontal crossbeam guided to move in said vertical and said inclined guide means; means for selectively opening said inclined guide means and closing the part of said vertical guide means located above its point of merging with said inclined guide means, or for closing said inclined guide means and opening said part of said vertical guide means; a dummy capable of rotating about said horizontal crossbeam element; and loading means attached to said horizontal crossbeam element for adding weight to said dummy.
Claim 12
Dependent Claim
38 words
The apparatus of claim 9, further including lower supporting means adjustably located in said vertical guide means and upper indicating means at upper ends of said vertical and inclined guides for indicating the force applied to said dummy.
Claim 13
Dependent Claim
17 words
The apparatus of claim 10 wherein said lower supporting means comprises resilient means which supports said crossbeam.
Claim 14
Dependent Claim
29 words
The apparatus of claim 9 wherein said inclined guide means is positioned with respect to said vertical guide means at an angle within the range of 15° to 85°.
Claim 15
Dependent Claim
40 words
The apparatus of claim 9 wherein said dummy is shaped like a human being and consists of an upper part rotatable about said horizontal crossbeam, and a lower part rotatable on a vertical axis with respect to said upper part.
Claim 16
Dependent Claim
31 words
The apparatus of claim 9 wherein the ends of said crossbeam extend outwardly beyond said frame, and said said loading means comprise a set of disks fitted on said extending ends.
