Abstract

A wearable exercise device in the form of a backpack has resistant pull cables at both shoulders and at both hips. Handgrips can be connected to the pulls in various ways to provide for varying degrees of resistance. The tension of the pulls is adjustable as is the mass of the backpack as a whole. A weight compartment can hold one or two weights of varying masses. The pulls at the hips can be connected either to handgrips or to the back of specialized shoes. When connected to shoes, the resistance of the pulls simulate running up hill.

Description

RELATED APPLICATIONS

This application claims priority from U.S. provisional application 61/297,903 filed Jan. 25, 2010, which is hereby incorporated herein by reference in its entirety.

FIELD

The teachings herein relate to exercise equipment; more specifically exercise equipment worn by the user.

BACKGROUND

Physical exercise is engaged in for general health and for athletic training as well as for other goals. Some forms of exercise are classified as aerobic, including walking, running, and cycling. Other forms are known as anaerobic including weight lifting and sprinting. While many exercise activities, such as walking, require no special equipment, a modern gym contains a wide variety of both simple and quite complex equipment—most of it being equipment fixed in place. It is desirable to have a relatively simple exercise apparatus that is highly portable and provides specific facilities to enhance both aerobic and anaerobic exercise.

SUMMARY

Apparatus and systems that can be in the form of a wearable, weighted apparatus with included cable pulls solve the problem of a portable multi-mode exercise device. In some versions consistent with these teachings, an apparatus in the form of a backpack can have resistant cable pulls at each shoulder and at each hip. Some aspects can include provisions for adjusting the resistance presented by the various pulls. Some versions can include facilities for attaching a pull to a handgrip. Some versions can include facilities for attaching a pull to a shoe. The worn apparatus can have compartments to accept weights of various masses.

DETAILED DESCRIPTION

In conjunction with the included drawings this detailed description is intended to impart an understanding of the teachings herein and not to define their metes and bounds.
Structure
The initial embodiment being described is an exercise apparatus in the form of a backpack as seen in FIG. 1. As shown in that figure there are tension cord termini at each shoulder and at the right hip. Not seen in FIG. 1 is a similar structure at the left hip. The unit includes a hard-shell housing 3, straps 4, and adjustments for the upper 15 16 and lower 17 18 tension cords respectively. As seen in FIG. 2, at each of the four points of tension cord termini there are, in fact, two cords shown. In each case there is a higher tension cord 15 17 and a lighter tension cord 16 18. Each cord is shown ending in a loop. To use the cords in any given position one, or the other, or both, can be attached to a handle 1 as seen in FIGS. 3 and 4.
As well as the tension cords, this unit also is weighted. As seen in FIG. 2 and FIG. 3 there is a foam pad 5 that would be against a wearer's back, for comfort. Behind the readily removable foam pad is a butterfly shaped weight compartment 19, seen in the exploded view of FIG. 3. This version can accommodate up to two weights 6 that are secured in place by locking knobs 20.
FIG. 4 shows an exploded view from the back. The major sub units of this version are a hard-shell housing 3, a base plate 2, the optional weights 6, and the straps 4. The base plate provides a mechanism to adjust the tension cords. Using the right shoulder cord ends 12 for explanation purposes, the higher and lighter tensioned cord ends 15 16 are seen in FIG. 5. As mentioned above, there are loops at each of the cord ends. Both cords are led through a cord guide 41 to an upper central tensioning mechanism 33. The structure is symmetric from left to right. The left and right shoulder cord end termini are ends of the same cord. The upper higher tension and lighter tension cords 15 16 go around dual spools 31 seen in FIG. 7. When the tension knob 32 is pressed in to become engaged, it provides for turning of the spools, thus increasing or decreasing the tension and resistance provided by the pair of cords. FIG. 6 shows the base plate 3 with the upper cord guides 41 removed.
The structure of the cords emanating from the housing 3 at the left and right hips and their tensioning mechanism is symmetric with that of the upper system described immediately above.
Kit
The Body Gym Backpack 50 described can be the foundation of a more complex exercise system. FIG. 8 shows an exercise bar 44 attached to the left and right shoulder cord loop ends 11 12. Rather than pull the left and right cords separately this allows them to be pulled together and would constrain the arm movements. In FIG. 9, a wearer is shown with the lower tension cords 17, 18 connected to the back of the heel of shoes 42 configured for this purpose. In FIG. 10, a shoe 42 is shown with a shoe loop 43 with a clasp 45 that opens and closes. FIG. 11 shows an enlarged view of the shoe loop 43 and clasp 45.
Variations
One set of variations of the above-described unit is to use only a single tension cord in some or all of the four portions. Another would be to locate access to the weight compartment differently, through the back, top, bottom or side, for example. If a device was desired primarily for use connected to shoes, a unit might only have the left and right two hip cord ends and therefore the base and housing might not be a full backpack configuration.

Alternate Embodiment

Constant Force Spring

Rather than using an elastomeric “bungee cord” spring resistance, embodiments might use a constant force spring. Such a version would use cords that are not substantially stretchable and would add a constant torque spring into the spool mechanism. The force of resistance could be changed by using alternate springs or by varying the effective diameter of the spool.
Operation
The body gym embodiment described above is a flexible device that can be used in many ways. A user can chose an amount of weight to add into the weight compartment 19 and can set the upper and lower tension to a desired degree of resistance. An additional flexibility is provided by having a pair of cord ends at each position. By connecting the load (either a handle 1, a bar 44, or a shoe 42) to one or the other or both end loops a great range of resistance is selectable by a user. Typical ranges of resistance might be 5 to 25 lbs for women and up to 40 lbs for men.
As seen in FIG. 12 a user might remain stationary while pulling up a cord 15 from his left shoulder and pulling down a cord 18 from his hip. In FIG. 9 a women is seen running with the right and left hip cords 17 18 attached to a specialized shoe 42 with a molded in hook, referred to as a shoe loop 43. Another use is seem in FIG. 8 In that use the bar 44 is attached to upper cords 15 16 at the users right and left and the bar is raised and lowered. In FIG. 13 a women is shown running while alternately pulling on the right 18 and left 17 hip position cords.
Other uses might include doing jumping jacks with the handles 1 on the upper tension cords 15 16 and the hip cords 17 18 connected to the specialized shoes 42.
FIG. 14 shows the unit of FIG. 1 and an exercise bar in perspective illustrating how the exercise bar might be connected to upper cords. FIG. 15 is a plan view of the unit from the top. FIG. 16 is a plan view of the unit from the bottom. FIG. 17 is an elevation view of the unit from the right side. FIG. 18 is an elevation view of the unit from the left side. FIG. 19 is an elevation view of the unit from the front. FIG. 20 is an elevation view of the unit from the back. FIG. 21 is a perspective view of the unit from the front, and FIG. 22 is a perspective view of the unit from the back.
