The weight holder device comprises a shear pin removably inserted through both the horizontal hole and the through bore and supports a variable number of upper plates of the stack, at least one end of the pin protrudes from the side of the supported plates, a holder formed by the protruding end of the pin retains a fractional weight releasably suspended therefrom. The holder includes an outer and an inner spaced discs radially extending from and coaxial with the pin.
Description
TITLE OF THE INVENTION
Weight holder device for weight lifting apparatus.
FIELD OF THE INVENTION
The present invention relates to a weight holder device, and more specifically to a weight holder device adapted to support fractional weights for weight lifting apparatus with weight stacks.
BACKGROUND OF THE INVENTION
It is known that using variable weight lifting exercise apparatus or the like, allows the user to lift a certain quantity of weight plates selected by the insertion position of a shear pin along the plate stack, each plate weighting the same amount that is sometimes considered as being significant. Unfortunately, for certain type of exercise, the user may be required to slowly increase the total lifted weight from time to time in order not to overcharge his/her muscles thereby inducing pain. This would not be possible with the standard weight of the plates being as heavy as 5 kilograms (or 10 pounds) each.
Therefore, it becomes apparent that there is a need for a user to be able to lift a fractional weight of a standard plate such as 1 or 2 kg (2 or 4 Ibs).
Harwick et al show in their two US Patents 4,712,793 and 4,787,628 granted on December 15, 1987 and November 29, 1988 respectively, two different devices installed on top of the upper plate of the stack. These devices are quite complex for the simple purpose they serve; they are found as kits that include a fractional weight support unit with its multiple small weights that are not that easy to install, and are also quite expensive. Also, the devices may not be suitable for all variable weight lifting exercise apparatus since the latter can be found with different stack plate attachment feature as well as with different plate sizes.
Furthermore, the user needs to take care of properly locating the fractional weights in order to ensure an adequate balancing of the overall stack to be lifted, fractional weights that need to be kept in a safe place to ensure that none of them get lost during the constant day-to-day usage of the apparatus.
OBJECTS OF THE INVENTION
The general object of the present invention is to provide a weight holder device for variable weight lifting apparatus that obviates the above noted disadvantages.
Another object of the present invention is to provide a weight holder device for variable weight lifting apparatus that is of simple and inexpensive construction.
A further object of the present invention is to provide a weight holder device for variable weight lifting apparatus that is adapted for use with any of the existing variable weights of standard weight lifting apparatus found in any fitness center.
SUMMARY OF THE INVENTION
The present invention consists of a weight holder device for use in combination with a weight lifting exercise apparatus that includes an upright stationary frame, a weight stack in said frame formed of several plates of equal size and weight, each plate having a vertical central through hole and a horizontal hole extending from a side of said plate to said central hole, a vertical plate lifting rod extending through said central holes of said plates and adapted to be displaced in an up-and-down movement by a user, said plate lifting rod having a horizontal through bore, said weight holder device comprises a shear pin removably inserted through both said horizontal hole and said through bore and

All plates 28 are essentially of equal weight and size.
Each weight plate 28 has a central through hole 30, two vertical lateral through holes 32 located on each side of the central hole 30 along the length of the plate 28 and a horizontal hole 34 extending from one long side of the plate 28 to the central hole 30, at least.
The upright frame 22 also includes two lateral guide rods 36 fixed thereto and extending through the lateral holes 32 of the plates 28 for guiding the latter in an up-and-down movement. A vertical plate lifting rod 38 extends through the central holes 30 of the plates 28. The plate lifting rod 38 has a plurality of horizontal through bores 40 in a number equal to the number of weight plates 28 in the stack 26, and each bore 40 is equally spaced from its next adjacent bore 40 by a distance equal to the thickness of the weight plates 28.
With all plates 28 aligned in the stack 26, the horizontal bores 40 are each coaxially aligned with their respective horizontal hole 34. The plate lifting rod 38 is adapted to be displaced in an up-and-down movement by a user U operated system. The latter is essentially composed of a cable 42 attached to the top of
4 the plate lifting rod 38 and running through different pulleys 44 to be terminated by a user handle 46.
During his period of exercise, the user U pulls on the handle 46 that in turn pulls on the plate lifting rod 38 via the cable 42 on the pulleys 44.
In its up-and-down movement, the plate lifting rod 38, supports a variable quantity of upper weight plates 28 that are temporarily secured thereto via a shear pin 48 that is inserted into both the horizontal hole of the lowest plate 28 of the variable quantity of upper plates and its corresponding through bore 40 of the vertical rod 38.
As shown in Figs. 2 and 3, at least one end 50 of the shear pin 48 of the present invention protrudes out from the side of the supported plates 28 and includes a weight holder 52 formed thereon. The weight holder 52 preferably includes a pair of an inner 54 and an outer 56 spaced flanges generally radially extending therefrom; the latter preferably being discs with the inner one 56 abutting against the side of at least the two lowermost of the upper plates 28.
The weight holder 52 is adapted to releasably support a fractional weight 58 that is suspended therefrom, the latter preferably weighs a fraction of the weight of each of the plates 28. The fractional weight 58 is preferably a standard ring (or disc) used on typical weight lifting bars thus already available in any fitness center and essentially having a sliding fit inbetween the two discs 54, 56.
The outer disc 56 is of an outer diameter d adapted to be of at most the inner diameter D of the central circular hole 60 of the typical ring 58, used as fractional weight, in order to be engaged by the latter. Preferably, the spacing between the two discs 54, 56 is essentially sized to provide a slidable engagement with the typical inner flange 62 thickness of small fractional weights 58.

Preferably, the spacing between the two discs 54, 56 is essentially sized to provide a slidable engagement with the typical inner flange 62 thickness of small fractional weights 58.
5 The preferred axial symmetry of the shape of the shear pin 48, including the weight holder 52, enables the user U to insert it into both the horizontal hole 34 of the lowermost of the upper plates 28 and its corresponding through bore 40 of the plate lifting rod 38 without having to worry about its orientation.
As an ordinary person skilled in the art would realize, the shear pin 48 is preferably made out of any highly resistant material with corrosion protection finish on surfaces, such as stainless steel or the like.
Although an embodiment has been described herein with some particularity and details, many modifications and variations of the preferred embodiment are possible without deviating from the scope of the present invention.
