What I now claim as new and desire to secure by Letters Patent as set forth in the United States Code Title 35 Patents is

1. An athletic training device comprising a horizontally disposed rectangular frame, the long sides of which are of hollow construction, having one end thereof fixed by cross bars while the other end thereof is provided with an extension , said extension consisting of a rectangular U-shaped structure the sides of which slide in and out of said hollow frame sides; correlated holes in the free ends of said hollow sides and in the sides of said U-shaped structure in combination with pins which pass through these holes for fixing the extended end in the required position; and a rectangular board of the same width as but shorter than said horizontal frame hingedly attached at the rear end thereof to the fixed end of said horizontal frame.

2. An athletic training device such as described in claim 1, in which the hinged board is provided with reinforcement bars, and the free end of which is rounded for convenient hand gripping.

3. An athletic training device such as described in claim 1, in which the hinges between the said board and horizontal frame consist of two bearing blocks fixed rigidly one at each side at the said one end of said horizontal frame; and a stub shaft, one at each side at said rear end of said board, which is held by and free to rotate within each of said bearing blocks.

The way in which this novel invention is used is clearly understood by examination of the accompanying drawings.

This invention relates to athletic training devices; more particularly, to training devices designed for athletes who are engaged in rigorous sports wherein the prime prerequisites are stamina and agility.

It is the principal object of this invention to provide an athletic training device of the character herein described that will permit the total coordination of all of the muscles of the body when the body is exercised on the device.

Another object of this invention is to provide an athletic training device of the character described that does not contain any weights, springs, or other mechanism that may require adjustment and/or replacement from time to time, or mechanisms which require operation by the person who is exercising, or operation by outsiders.

Another object of this invention is to provide an athletic training device of the character described that can be manufactured from any available material, such as wood, metal, plastic or the like and/or a combination of the aforesaid materials.

Still another object of this invention is to provide an athletic training device of the character described that is adjustable for use of persons of varying heights.

Other and further objects and advantages of this novel invention will no doubt appear to those experienced in the art as the reading of this specification and its appended claims proceeds and the accompanying drawings are examined in connection therewith.

In the drawings:

FIG. 1 is a pictorial view of this invention in its folded position.

FIG. 2 is a pictorial view of this invention in an open position ready for use.

FIG. 3 is a pictorial view of an athlete using this invention and in the starting position.

FIG. 4 is a pictorial view of an athlete in the second position on this invention.

FIG. 5 is a pictorial view of an athlete in the third position on this invention.

FIG. 6 is a pictorial view similar to that of the last three views except that it is in a fourth position.

In the several views of this invention, like parts of the device are indicated by like reference numbers. The reference number 10 indicates the invention in its entirety.

Directing one's attention to FIGS. 1 and 2 of the accompanying drawings it will be seen that this invention 10 consists of two spaced and parallel square tubes 11 that are firmly secure together at one end by two like tubes 12, as one can clearly see by examination of the aforesaid FIG. 2 of the drawing. A bearing block 13 is located on the upper surface of one end of each tube 11 for the reception of the stub shaft 14 that extends outward from one end and side of the rectangular board 15. The bearing blocks and stub shafts obviously form hinges for the just-mentioned rectangular board 15 whose underside is provided with two bars 16 that are square when viewed from the ends. There is one bar along each longitudinal edge of the aforesaid board 15. It will be noted on examination of FIGS. 2 and 5 of the drawings that the two aforesaid bars 16 are not only set back longitudinally from the front and rounded edge 17 of the board 15 but are also cut or otherwise formed at an angle. The purpose of this novel construction is to permit the fingers of the athlete to grip the front edge 17 of the board when this invention is in use, as can be seen on examination of FIGS. 3, 4 and 5 of the accompanying drawings.

Continuing to look at FIGS. 1 and 2 of the drawings one will see that this invention also consists of two parallel and equally spaced square bars or tubes 18 that are adapted to slide into the first-mentioned tubes 11. The outer end of each bar or tube 18 is suitably secured to a crossbar or tube 19 which along with the two longitudinally disposed tubes 18 form a U-shaped member 20 which is longitudinally held in place in the two aforesaid tubes 11 by means of two vertically disposed pins 21. One of the aforesaid vertically disposed pins 21 is in each tube 18 and projects up through an opening in each tube 11, as one can clearly see by looking at FIG. 2 of the drawings. The aforesaid crossbar or tube 19 is a foot brace bar that can be moved outward from the rest of the invention when the athlete is a tall person, as can be seen in the drawings.

Having now described the actual construction of this novel device the way in which it is used is given as follows:

From a closed or starting position on the aforesaid training device 10 the performing athlete sits down squarely on the aforesaid rounded front end 17 of the rectangular board 15, sitting in an upright position. By raising his knees to form an approximate 45 degree angle in relation to the floor or whatever the invention is resting on, the athlete places his feet flat on the floor or the like against the two aforesaid longitudinally disposed square tubes 22 with his toes pressing firmly against the aforesaid crossbar or tube 19 which is the foot brace bar. The athlete then extends his hands forward with the arms snug against his hips and grips the aforesaid rounded end 17 of the board 15. This position of gripping is very important in order to insure the correct alignment of the shoulders and knees. The athlete now reclines or lies down flat on his back, as is illustrated in FIG. 3 of the accompanying drawings, with his hips back, shoulders and head touching the board 15. In this position, the athlete must adjust in relation to the position of his hips on the often-mentioned board 15 and the length of his arms gripping the aforesaid rounded front end 17 of the board. Also, the aforesaid crossbar or tube (foot brace) 19 must now be adjusted, if need be, to accommodate the length of the legs of the athlete in forming the aforesaid 45° the raised knees form in relation to the floor or the like. With the foregoing accomplished, the performing athlete is now ready to commence the exercise which results in bringing the entire body from a horizontal to a vertical or standing position, as is shown in FIG. 6 of the accompanying drawings. The athlete must concentrate on what his various muscles in the various parts of his body are called upon to do in unison. The performing athlete must inhale and exhale several times while setting up a mental rhythm or timing, then, with the lungs two thirds filled the athlete starts the exercise movement.

The exercise movement is accomplished by applying extraordinary strength, pushing forward with the legs and thighs, and pulling straight back with the arms and shoulders while raising gradually upward with the center of the body; carrying along with the body the movable end of the aforesaid board 15 to a point where the legs and thighs have been fully extended. From this arched position, the athlete continues the pull with the center and upper part of the body to raise the head and shoulders from the reclined horizontal position to the vertical standing position. In doing this the strain is relieved and the weight is shifted from the horizontal to the vertical position. The push pressure from the toes upon the foot brace bar 19 can be relieved by taking a few short steps backward, thus straightening the body to a normal standing position. While doing this exercise, bringing the body from a horizontal to a vertical position, it is essential that the performing athlete does not let go of his grip on the aforesaid board 15.

At such time that the athlete becomes proficient in doing this exercise, bringing the body from a horizontal to a vertical position, he can further use this novel training device 10 by executing the process of the device in the reverse, that is, going from a vertical to a horizontal position. This is accomplished by placing the toes against the aforesaid foot brace bar 19, reaching back and gripping the aforesaid front end 17 of the board 15. Positioning is at hip level and slowly proceeding backward and downward into the arched horizontal position shown in FIG. 4 of the accompanying drawings, then into the closed or original starting position. This is a tricky movement and requires equally and as much exacting on all counts as do the original horizontal to vertical position.

This invention is subject to any and all changes in detail design and/or modifications one may care to make in so long as the changes and/or modifications fall within the scope and intent of the appended claims.
