Description:
SUMMARY OF THE INVENTION
The present invention relates to exercising devices and more particularly to an improved arm exercising device to be gripped by both hands of a user for the purpose of rotating a pair of weight members.
It is a particularly important feature of the present invention that each weight member includes a container, which is formed of a pliable material and adapted to receive quantities of a flowable material, such as water, sand or shot. The effective weight of weight members may be selectively varied by varying the quantity of flowable material within the container with the aid of visual indication imprinted thereon. The construction of the container and nature of its contents reduces the likelihood that serious injury would result from improper use of the exerciser.
In an alternative form of the present invention, the hand grips whose movement impart rotational movements to the weight members, are supported on opposite ends of the hand grip connecting shaft for free sliding reciprocating movements lengthwise thereof, that is, movement in directions towards and away from one another. Coil springs are employed to resiliently resist or oppose sliding movements of the hand grips towards one another. During use of the exerciser, a user may endeavor to continuously force the hand grips towards one another or attempt to maintain them in a given spaced relationship. In either case, the muscles of the user will be exercised in a novel manner.

The nature and mode of the present invention will now be more fully described in the following detailed description taken with the accompanying drawings wherein:
FIG. 1 is a perspective view of the arm exerciser of the present invention;
FIG. 2 is a sectional view taken generally along line 2--2 in FIG. 1;
FIG. 3 is a sectional view taken generally along line 3--3 in FIG. 1, but showing a modified construction; and
FIG. 4 is a view similar to FIG. 2, but showing a modified form of the present invention.
DETAILED DESCRIPTION
Reference is now made particularly to FIG. 1, wherein the exercising device of the present invention is generally designated as 10. Exercising device 10 includes a shaft member 12; a pair of hand grips 14, 14; a pair of weight bearing devices 16, 16; and a pair of weight members 18, 18.
In a preferred construction of device 10, shaft member 12 is in the form of a metal rod, and hand grips 14, 14 are in the form of contoured or roughened surfaced plastic sleeves fitted over reduced diameter end portions of the shaft member, only one end portion being shown as 12a in FIG. 2. Also, as best shown in FIG. 2, each of bearing devices 16, 16 may be conveniently formed from a bolt 20 having one end threadably received concentrically within end portion 12a. As will be apparent, the bolts support weight members 18, 18 for rotational movements within parallel planes and about an axis 20a, which extends lengthwise of shaft member 12. Alternatively, shaft member 12 may be in the form of a tube fitted with threaded end plugs to support the bolts and/or hand grips 14, 14 may be formed integrally with the shaft member.
In FIGS. 1 and 2, each of weight members 18, 18 is shown as including arm member 24, which is supported adjacent one end thereof by one of bolts 20, and a container or chamber device 26, which is carried by the other end of arm member 24. Containers 26 are adapted to receive a flowable material, which is preferably water, but may be for instance, sand or small shot.
Arm member 24 is shown in the drawings as being in the form of a bendable plastic tube, which preferably has its bearing end reinforced, as by a suitable insert 28 in the form of a wooden plug 30 bored to receive a Nylon or like material wear sleeve 32. Preferably, the ends of sleeve 32 are arranged to project outwardly through aligned arm wall openings 34, 34 in order to space the arm from the head end of bolt 20 and shaft end portion 12a.
Containers 26 are preferably in the form of bottles blow-molded from a pliable plastic material, which is sufficiently transparent to permit a user to visually determine the degree to which the bottle is filled with water. As indicated in FIG. 1, the neck end of the bottle may be sealed and permanently fixed within the end of its associated arm 24 as by screws or adhesive, not shown, and water added or removed, as desired, through a side wall located access opening sealable for instance by a stopper or plug 36.
To aid a user in determining the volume of water within the bottle and thus the effective weight thereof, suitable indicia may be imprinted on the side wall of the bottle, as indicated at 38.
To operate unit 10 as thus far described, a user would add water to containers 26, 26 to obtain a desired exercise weight. Then the user would grip hand grips 14, 14 and with both arms held generally outstretched or with elbows adjacent his sides, and impart movements to shaft member 12 laterally of axis 20a, thereby to produce rotational movements of weight members 18, 18. By forming containers 26, 26 from a pliable material and filling same with a flowable material, the likelihood of injury to the user and/or adjacent objects due to improper or careless operation of device 10 is greatly reduced.
According to an alternative form shown in FIG. 3, the neck end of the bottle may be removably screw threaded into the end of arm 24 to permit filling of the bottle through its mouth in the normal manner. In this construction, escape of water into arm 24, when the device is not in use, may be prevented by forming arm 24 with an internal partition 40 or merely by employing a stopper to removably close the bottle mouth.
Reference is now made to FIG. 4, which illustrates an alternative form of the present invention, wherein a pair of hand grips 14' are removably mounted for sliding movements on opposite ends of a solid shaft 12' in directions towards and away from one another, and serve to carry associated bearing devices 16' and sliding movement limiting or opposing coil type compression springs 42 engaging both the shaft and hand grips. In this construction, each of hand grips 14' is formed with a cylindrical recess 44, which is dimensioned to loosely receive an end of shaft member 12'; and each of bearing devices 16' includes a bearing shaft portion 46, which is formed at one end with an opening threaded to receive a headed retainer bolt 48 and fixed adjacent an opposite end to an enlarged cup-shaped mounting portion 50. Mounting portion 50, which is suitably fixed within recess 44 as for example by welding or adhesive, frictionally receives one end of an associated coil spring 42, whereby to mount such spring on its associated hand grip concentrically within recess 44.
An exerciser unit including the construction illustrated in FIG. 4 may be operated in the same manner as that described above in connection with the embodiment of FIGS. 1 and 2. However, during use, the user may also endeavor to continuously or intermediately force the hand grips towards one another against the bias of springs 42 or attempt to prevent any movement of the hand grips from a given spaced relationship, wherein the springs are partially compressed or completely released. In any event, the user's muscles will be exercised in a novel manner.
While hand grips 14' are preferably made readily removable from the shaft member 12' in order to permit their independent use, suitable constraints, not shown, may be employed to insure against unintentional separation of the hand grips from the shaft member during use.
The present invention relates to exercising devices and more particularly to an improved arm exercising device to be gripped by both hands of a user for the purpose of rotating a pair of weight members.
It is a particularly important feature of the present invention that each weight member includes a container, which is formed of a pliable material and adapted to receive quantities of a flowable material, such as water, sand or shot. The effective weight of weight members may be selectively varied by varying the quantity of flowable material within the container with the aid of visual indication imprinted thereon. The construction of the container and nature of its contents reduces the likelihood that serious injury would result from improper use of the exerciser.
