LATERALLY PIVOTED WEIGHT TRAINING DEVICE

BACKGROUND OF THE INVENTION

L Field of the Invention
The present invention relates to exercising devices for developing and conditioning various parts of the body and, more particularly, for developing neck muscles.
2. Description of the Prior Art
Many exercising devices have been developed for improving muscular strength and endurance of various parts of the body. Those that have been developed for exercising the muscles of the neck typically incorporate cumbersome and uncomfortable head-engaging harnesses to which a force resister, such as a weight, is applied. Many of these
< are portions of complex and costly "universal" exercising machines which are not suitable for home use.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to obviate the above-noted disadvantages of the prior art by providing a simple, inexpensive and comfortable exercising device for developing the muscles of the neck and other portions of the body.
Another object of the invention is to provide such a device which is used in conjunction with the weights of a common barbell set.
Another object of .the invention is to provide such a device which does not require a complex and cumbersome head-engaging harness for operation.

Another object of the invention is to provide such a device which is designed to be easily assembled by the consumer using a minimum number of conventional hand tools.
Another object of the invention is to provide such a device which is adjustable to suit the needs of various users.
These and other objects of the present invention are accomplished by providing an exercising device for use with interchangeable weights of selected quantity comprising an inverted, generally J-shaped frame having a generally upstanding lower portion, and a generally arched upper portion joined at one end to the lower portion along a back side of the frame and having a free opposite end, the frame being adapted to be supported in a stationary position relative to a user-supporting surface. A weight support means is pivoted to the back side of the frame for pivotal movement about a substantially horizontal axis, the weight support means including a user-engageable. lower lifting surface against which a generally upward exercising force is applied to pivot the weight support means about the axis and raise the weights supported thereon. A stop means is carried by the frame in the region of the free end of the upper portion for supporting the weight support means in a lowest rest position wherein the weights are disposed substantially laterally of the vertical plane containing the pivot axis.
Preferably, the weight support means comprises a pivoted padded board having an upstanding post for engaging the holes of the apertured weights of a barbell set. The frame means preferably comprises two spaced tubular legs which are adapted to be adjustably supported in mounting brackets affixed to the legs of an exercising bench or any other suitable supporting structure.
BRIEF DESCRIPTION OF THE DRAWINGS
The novel features of the invention are set out with particularity in the appended claims, but the invention will be understood more fully and clearly from the following detailed description of the invention as set forth in the accompanying drawings, in which:
Figure 1 is a perspective view of the exercising device according to the invention showing its use in conjunction with an exercising bench having mounting brackets for securing the device thereto; and

OMPI Figure 2 is a side elevational view of the same illustrating its manner of use.
DESCRIPTION OF THE INVENTION
In the preferred embodiment shown in the figures, most of the structural elements of the invention are tubular steel members which are secured together by bolted connections. This arrangement permits the components of the device to be marketed in a compact package, and readily assembled using conventional hand tools. Of course, other types of members of various cross-section may be used, and they may be secured together by other means, such as welding.
The exercising device according to the invention includes a frame 20 comprising a pair of laterally spaced, inverted J-shaped members 22 which may be supported in the mounting brackets 12 of an exercising bench or any other suitable supporting structure. J-shaped members 22 include vertically spaced holes 24 which may be selectively aligned with holes 14 in brackets 12 to adjustably secure the device at a desired height from the floor by means of shear pins (not shown). A tubular crosspiece 26 is bolted across the back sides of the J-shaped members 22 just beneath their curved upper portions. A tubular strut 28 is bolted across the tips of the curved portions.
A pivoted weight support 30 comprises two spaced parallel arms 32 which are pivotally mounted on crosspiece 26 by means of cylindrical collars 34 welded to the ends of arms 32. The free ends of arms 32 are secured to a padded board 36 by means of screws 38. Board 36 may comprise a plywood base having a lower padded surface of vinyl-wrapped polyurethane foam. Conventional flanged tubular nuts (not shown) are secured in predrilled holes in the plywood base and are engaged by screws 38 to secure board 36 to the arms 32.
Selected apertured weights W are retained on weight support 30 by means of an upright post 40 welded to a plate 42. Plate 42 is screwed to the top of board 36 by flanged tubular nuts (not shown) or other equivalent means.. Arms 32 are spaced apart so that the weights W placed on post 40 are supported on the arms themselves above board 36. In this way, all of the weight is borne by the arms 32, thereby preventing undue stresses on the board 36 and its connections with arms


Referring to Figure 2, the operation of the exercising device will now be described. For developing the muscles at the back of the neck and the shoulders, the user adjusts the height of the device relative to the floor such that, when on all fours, the back of the user's head, when held substantially horizontal, will contact the padded underside of board 36. The user then lifts his head to pivot weight support 30 about crosspiece 26 and raise weights W. The weights need be raised only a small distance. The user then lowers his head to permit weight support 30 to come to its rest position with arms 32 in contact with strut 28, which acts as a stop. The head raising and lowering movements are repeated for a desired number of times to complete the exercise.
The exercising device may also be used to develop muscles at the sides of the neck by raising and lowering the weight support with the side of the head. In this situation, the exercising device would be lowered to a position such that the user can comfortably support himself on the floor on his side and elbow or in any other comfortable manner while performing the desired exercise. Of course, the exercising device of the invention is not limited to performing neck muscle developing exercises, and may be used to develop any portions of the body which can conveniently be arranged beneath weight support 30 to raise and lower weights W.
Advantageously, the rest position of weight support 30, with arms 32 abutting strut 28, is such that weights W are disposed substantially at a maximum horizontal distance from the pivot axis defined by crosspiece 26. In this manner, the lifting force exerted by the user can be conveniently directed substantially upwardly against board 36. This is the most efficient arrangement since the weight moment of the weight support 30 and weights W about the pivot axis is a maximum. Of course, the rest position of weight support 30 could be arranged so that weights W are disposed at a lesser horizontal distance from the pivot axis. The device could still function in this manner, although not as effectively, as long as weights W are disposed substantially laterally of the vertical plane containing the pivot axis.
