## Background
BACKGROUND OF INVENTION
The present invention relates to a device in a kit for stretching the body.
A regular program of physical exercise is important to the physical and mental health of persons. Many people exercise at health and exercise facilities under the guidance and instruction of a trained exercise director. Other persons exercise alone or at home. Exercise takes on a variety of routines, including, but not limited to, yoga, martial arts, aerobics, swimming, running, cross-training, and gymnastics.
The stretching of the muscles, ligaments and other body tissues improves flexibility, reduces muscle cramping and strains or other forms of injuries, and improves exercise performance and endurance. Safely stretching tight muscles prior to an activity may help prevent soft tissue trauma during activities. Re-stretching during the cool-down phase after the completion of the activity minimizes muscle soreness and helps to elongate tissues that may become tight during the activity.

DETAILED DESCRIPTION
FIG. 1 shows an embodiment of an exercise device 10 of the present invention. The device includes an elongated member shown as a length of a flexible strap 12 and a connector assembly 30. The strap 12 has a first end 14 and a second end 16. The strap is inelastic and is typically made of a polypropylene, nylon or other thermoplastic, resilient woven material, but could be made of cotton, hemp, or other natural fiber woven material. The strap typically has a width of at least about 1.5 inches, and up to about 4 inches, and more typically of at least about 2 inches. The strap 12 typically has a length, from the first end 14 to the second end 16, with the connector 30 in the disconnected configuration, of about 8 feet, and up to about 12 feet, and more typically of about 10 feet.
The connector assembly 30 comprises a movable member  32 configured for positioning along a portion of the length of the strap 12, and a fixed member 36 that is attached to the second end 16 of the strap. The movable member 32 has a pair of adjoining slots through which the length of strap can pass and thereby engage with the movable member 32, thereby providing a loop-forming portion 52 of strap that extends from the movable member 32 toward the second end 16, and a trailing portion 54 of strap that extends from the movable member 32 toward the first end 14. The movable member 32 can be positioned along the length of the strap 12 by grasping the movable member and pulling on either the loop-forming portion 52 or trailing portion 54 of strap 12, so that the strap passes through the slots of the movable member 32.
The connector assembly 30 also comprises a fixed member 36 configured for attachment to the second end 16 of the strap. A typical attachment of the fixed member 36 is made by passing a leading portion 26 of the strap stock proximate the second end 16 through a slot in the fixed member 36, folding the leading portion back onto the strap, and securing the leading portion 26 to the strap with a securement, such as stitching 28.
A typical connector assembly is a snap buckle, such as an Airloc Side Release Buckle, available from ITW Nexus U.S, Des Plaines, Ill., or a Side Release Buckle, available from Fasnap® Corporation, Elkhart, Ind. Such snap buckles are typically made of a plastic material and are available in a variety of sizes to accommodate straps of various widths.
The strap has a fixed loop 20 formedproximate the end 14 by folding a leading portion 22 of the strap stock back onto mid-length portion of the strap, and securing the leading portion 22 to the mid-length portion with a securement, such as stitching 24. The fixed loop 20 is configured for fitment over a user's foot, hand, leg, or arm during the stretch exercise. The fixed loop typically has a circumference of at least about 14 inches, and up to about 18 inches, and more typically of about 16 inches.
As shown in FIG. 2, the connector assembly 30 has a connected configuration wherein the fixed member 36 and the movable member 32 are connected together, thereby forming a second loop 60 proximate the second end 16 of the strap. Typically, the connector assembly 30 is configured with a release button or other means for releasing the fixed member 36 from the movable member 32, into the disconnected configuration shown in FIG. 1.
Other connectors can be used to releasably connect the second end 16 with a mid-length portion of the strap 12 to form the second loop 60 of varying circumference. Non-limiting examples of such other connectors can include a mechanical hook and loop fastener, cap and button snaps, and others.
The size of the second loop can be varied by grasping the connector assembly 30 and pulling on either the loop-forming portion 52 or trailing portion 54 of the strap. Pulling on the loop-forming portion 52 will cause the second loop 60 to become larger in circumference, while pulling on the trailing portion 54 will cause the second loop 60 to become smaller in circumference.
The connector assembly 30 is configured to resist movement along the length of the strap while the device, in its connected configuration, is in use. That is, the connector assembly 30 resists movement along the strap 12 when opposed forces are applied to the loop 60 and to the trailing portion 54 of the strap.
The exercise device 10 can be used in one or more configurations for use in assisting a person to stretch a targeted tissue in the body. One device configuration provides use of the device with the connection assembly in a disconnected configuration, having only a fixed loop 20. In this configuration, the user can grasp and restrain the strap at a point along the mid-length of the device. Another device configuration provides use of the device with the connection assembly 30 in a connected configuration having both the first loop 20 and the second loop 60. In various alternative configurations of the exercise device having both the first loop and the second loop 60, the position of the movable member 32 can be varied to provide the second loop 60 with correspondingly varied circumferences. One such configuration provides the second loop 60 with a circumference of at least about 14 inches to about 18 inches, and more typically of about 16 inches, but can be up to nearly the entire length of the remaining part of the strap. Since the size of the second loop 60 can be adjusted, the overall length of the strap 12, from the first end 14 of the fixed loop 20 to a distal end of the second loop 60, can correspondingly vary. The adjustability of the size of the second loop 60 allows for fine adjustment of the overall length of the strap. The fine adjustment of the overall length of the strap 12 can provide more effective use of the device by persons of all sizes while performing a wide variety of stretching exercises. In this configuration, the user may use only the expandable second loop 60, or may use both the fixed loop 20 and the second loop 60, as illustrated in FIG. 5.
Another embodiment of the present invention is a kit for use in assisting a person to stretch a targeted tissue in the body. The kit comprises an exercise device as described herein above, and instructions that inform a user of the proper use of the device to stretch a corresponding plurality of targeted tissues in the body. The kit also comprises a means for securing the exercise device with the instructions.
The instructions can be in a variety of forms that can explain or show the user the proper use of the exercise device in stretching a targeted tissue of the body. Typically, the targeted tissue is a muscle, a ligament, a tendon, and combinations thereof. More typically, the instructions inform the user of a plurality of proper uses of the device, to stretch a corresponding plurality of targeted tissues in the body. The instructions can be observed and used directly by a user of the exercise device, or can be observed by an instructor, who then directs the user in the proper use of the device.
A typical securement means for the kit comprises a package that encloses the exercise device and the instructions. Typically, the package is closed for shipment and storage of the kit, such as for transportation through commerce to a retail or wholesale store, or to a facility (including, but not limited to, an exercise facility, rehabilitation facility, hospital, clinic, yoga studio, martial arts training center, or a residence) where the device will be used. As shown in FIG. 3, a typical package is a closed transparent thermoplastic container 80 that has a backopening that is initially covered by a secured, hinged lid 81. A set of written instructions 90 are folded and positioned within the container. The exercise device 10 is typically rolled or folded, and placed within the container 80. The container can have a label 88 for commercial purposes that can be positioned and secured on the inside of the container, facing outward, as shown in FIG. 3, or on the outside of the container. The container 80 can be sized depending upon the length and width of the strap of the exercise device, and on the type and quantity of instructions. For example, when the instructions include a video tape, the container should be sized with dimensions to contain the videotape.
Another embodiment of a kit of the invention uses a securement means that comprises a shrink-wrap plastic film, or a plastic bag that is secured closed to contain the exercise device and instructions.
The instructions are selected from the group consisting of written instructions, pictorial instructions, audio instructions, video instructions, and mixtures thereof. Typically instructions include a combination of written instructions and pictorial instructions, in the form of an instruction sheet or card.
FIG. 4 shows an instruction as an instruction sheet 90 comprising a plurality of written exercise instructions 92 and a corresponding plurality of pictorial instructions 94.
A typical written exercise instruction 92a includes a description heading 96 and (one or) a plurality of steps 98a, 98b, and 98c of a method of using the exercise device in stretching a targeted tissue of the body. The written exercise instruction 92a is proximally associated with a pictorial instruction, shown as image 94a, to assist in understanding the instruction for using the device. Each written exercise instruction 92 can be directed to a different targeted tissue of the body for stretching, such as calf muscles, hamstring muscles, and others.
The instructions can be used to direct the user in a wide variety of stretching exercises. Typical examples include a straight leg stretch or release (release is an alternative term for stretching), hip release to the outside or to the inside, groin release, full body release, arms overhead release, and chest release. One example of an exercise instruction is provided for a stretching exercise called “groin release”.
