BEST MODE TO PRACTICE THE INVENTION

[0054] Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings to be easily practiced by one of ordinary skill in the art.

[0055] As shown in FIGS. 1 to 8, the present invention relates to a wearable arm exerciser 100 useable while walking, which enables natural movement of both arms and legs while walking upright, and the wearable arm exerciser 100 basically includes

[0056] weaving belts 110 coupled with a fastening means 111 to stably fasten the structure to a user's body to start from the user's chest, pass through the user's shoulders and cross each other in an X shape,

[0057] a pair of elastic strings 120 coupled with first connecting rings 113 and second connecting rings 114, which are connected to the webbing belts 110 on the user's chest and back, through first connecting means 121 and the second connecting means 122, respectively, while passing upper and lower parts of the shoulders, formed of one or more elastic wires, and forming closed loops with the webbing belts 110, and

[0058] an anti-friction device 150 mounted at lower parts of the pair of elastic strings 120, having a circular arc shape to allow the elastic strings 120 to slide according to movement of a handle to thereby prevent friction, positioning the handle at the lowest point of the elastic strings 120, and minimizing the abrasion of the elastic strings 120, and

[0059] the handle 130 coupled to the anti-friction device 150 and gripped by the user. When moving her arm backward (e.g., extending) while walking, the user pulls the handle 130 to stretch the elastic strings 120 and contract the triceps brachii, and extend the elbow joint.

[0060] The wearable arm exerciser 100 further includes a waist string 140 connected, via waist couplers 141, to third connecting rings 132 located opposite the handle couplers 131 with respect to the (pair of) handles 130 to exercise the biceps brachii. At this time, the waist string 140 is a long elastic string with both ends connected with the waist couplers 141 to be coupled with the handles 130. As shown in FIGS. 1 to 7, the handle couplers 131 and the waist couplers 141 produce a gap for insertion when pressed, for coupling and decoupling, by the user to move their part and, when the pressure is removed, the part is moved back to its original position to prevent the inserted ring from escaping off. The handle couplers 131 and the waist couplers 141 may have any other configurations for coupling or decoupling. The same is true for the first connecting means 121 and the second connecting means 122 described below.

[0061] The elastic strings 120 and the handles 130 of the present invention are used in both hands. Thus, two elastic strings 120 and two handles 130, one on one side of the chest and the other on the other side of the chest, are installed.

[0062] The shoulder joint consists of three bones, i.e., clavicle, scapula, and humerus and their related muscles, ligaments, and tendons. Shoulder joint means a joint where the clavicle and the humerus meet together, in a narrow meaning, and all joints which are formed as the three bones, in a broad meaning. When a problem with the shoulder joint arises, all of the user's activities which are routinely done, such as washing or bathing, are limited.

[0063] Thus, according to the present invention, there is provided a wearable arm exerciser 100 usable while walking in which, as the user moves his arms while walking, the elastic strings 120 produce tension that is then transferred to muscles around the shoulders and repetitive extension and flexion of the arms leads to contraction and relaxation of the around-shoulder muscles, reinforcing muscular flexibility, prompting body fluid circulation, allowing for recovery of the mobility of shoulder joint, preventing shoulder disease, and relieving pain.

[0064] The webbing belts 110 are formed of straps that are non-extendable against strong impacts and that, starting from the user's chest, pass the user's shoulders and cross each other in an X shape. The webbing belts 110 are connected to the elastic strings 120, with the X-shaped crossing of the belts facing the users back, to be worn on the user's shoulders.

[0065] When the user pulls the detachable left and right handles 130, which are coupled to the elastic strings 120 connected up and down to the webbing belts 110 to form closed loops, after wearing the webbing belts 110, the elastic strings 120 may extend in the direction when the user's arms move and remain in tension.

[0066] The webbing belts 110 have the fastening means 111 to stably fasten the structure to the users body to be crossed in an X shape on the user's back. The fastening means 111 have fastening holes spaced apart in three or four directions, to allow the webbing belts 110 to be inserted, crossed, thereto.

[0067] The fastening means 111 may be distinctively provided for men or women. The fastening means 111 may be polygonal in shape when used for men, according to the first embodiment of the present invention as shown in FIGS. 1 to 4 and be circular in shape when used for women, according to a second embodiment of the present invention as shown in FIG. 5. The above-described shape of the fastening means 111 depending on whether it is used for en or women is merely an embodiment and the fastening means 111 may be produced in other various shapes.

[0068] Where formed in three directions, the fastening holes may include a first fastening hole, a second fastening hole, and a third fastening hole. Where formed in four directions, according to the first and second embodiments, as shown in FIGS. 3 and 5, the fastening holes may include a first fastening hole 111a, a second fastening hole 111b, a third fastening hole 111c, and a fourth fastening hole 111d.

[0069] When provided for men's use, the fastening means 111 may have an upper side wider than a lower side to allow the webbing belts 110 to be coupled in a broader area and thus stably fastened for male adults with broad shoulders.

[0070] When provided for women's use, the fastening means 111 which is circular in shape has a first fastening hole 111a, a second fastening hole 111b, a third fastening hole 111c, and a fourth fastening hole 111d which have the same shape and project in four directions.

[0071] Coupling means 112 each of which is formed by a female buckle member and a male buckle member which are cable of length adjustment and coupling and decoupling of the webbing belts 110 are provided to the webbing belts 110 to allow the user to perform length adjustment and coupling and decoupling even without taking off the wearable arm exerciser 110 already worn.

[0072] The coupling means 112 are placed on the user's chest near the shoulders when the user wears the wearable arm exerciser 100.

[0073] Thus, the user may easily adjust length after wearing the wearable arm exerciser 100 of the present invention.

[0074] The coupling means 112 are provided to allow for length adjustment and are formed of a female coupling member at one side thereof a male coupling member at an opposite side thereof to, when coupled together, enable coupling of the webbing belts 110 and, when decoupled from each other, allow the wearable arm exerciser 100 from being removed the user's body.

[0075] The fastening means 111 formed as a clip to fasten the webbing belts 110 crossed in an X shape on the user's back is provided at the webbing belts 110, keeping the webbing belts 110 separated left to right.

[0076] The first connecting means 121 and the second connecting means 122 are provided at the first connecting rings 113 and the second connecting rings 114 which are provided at both ends of the webbing belts 110 and are coupled with the elastic strings 120. An anti-friction device 150 mounted at the lower part of the elastic strings 120 to prevent friction by sliding according to movement and positioning the strings at the lowest point of the strings and a handle coupler 131 are used to couple the handle 130.

[0077] The first connecting rings 113 and the second connecting rings 114 are formed as closed rings. The first connecting means 121 and the second connecting means 122 are formed as rings that may be open and closed to be coupled to or decoupled from the first connecting rings 113 and the second connecting rings 114.

[0078] The webbing belts 110 have shoulder pads 115 which are formed of flexible rubber or plastic and which allow the webbing belts 110 to be stably fastened onto the user's body with reduced friction on the user's shoulders.

[0079] The detachable, ring-shaped first connecting means 121 and second connecting means 122, respectively, are provided at both ends of the elastic strings 120. Provided are covering means 123 to cover the elastic strings 120 which have elasticity. As illustrated, one covering means 123 may be provided. Alternatively, a plurality of covering means 123 may be provided and spaced apart from one another.

[0080] The covering means functions to prevent friction to the user's body when the elastic strings 120 extend or contract while preventing an accident that may occur when the elastic strings 120 are disconnected. In other words, the elastic strings 120 may impact and injure the user's body by their own elasticity. However, where an elastic string 120 is disconnected, the elastic string 120 is first moved inside the covering means 123 and, thus, the user may be prevented from injury.

[0081] The covering means is formed of an empty tube with a width enough to allow the elastic string 120 to freely travel back and forth thereinside.

[0082] The elastic string 120 may be formed of one or more wires depending on the strength of exercise. Where the elastic string 120 is formed of four wires, there are provided larger rings (not shown) hung on the four wires and a smaller ring (not shown) hung on two of the four wires.

[0083] The elastic strings 120 are detachably coupled at both ends thereof to the webbing belts 110 so that the webbing belts 110 and (one pair of) left and right elastic strings 120 form closed loops. Thus, when a force occurs anywhere in the elastic string 120, the overall elastic string 120 is tensioned and, when tension occurs at a side in the middle of the elastic string 120, the tension may be separated from where the tension occurs, and the first connecting ring and the second connecting ring of the webbing belts 110 are pulled and tensioned, Therefore, when the user swings to move up or down his arm so that the handle grabbed in the hand 130 is moved, the handle coupler 131 coupled with the handle 130 is tensioned from the handle 130, allowing the elastic string 120 to extend at the front and rear of the shoulder. The anti-friction device 150 is mounted at the lower part of the elastic strings 120 and slide according to the movement of the handle 130 to thereby prevent friction with the strings and keeps the handle at the lowest point of the strings. The anti-friction device 150 minimizes friction with the elastic strings 120 and the handle coupler 131 and allows the handle to move to the lowest point along the elastic strings and, as the user exercises, the same amount of tension is generated by the handle 130 at the front and back of the elastic strings 120. In other words, the same amount of tension is generated on both (front and rear) sides of the elastic strings 120 coupled to both sides of the anti-friction device 150.

[0084] The handle 130 is provided to be movable on the elastic strings 120 between the covering means 123 and is connected to the ring-shaped handle coupler 131 that may be open and closed.

[0085] The handle 130 is coupled, via the handle coupler 131, with the anti-friction device 150 that is mounted at the middle portion, i.e., the lowest portion, of the elastic strings 120 to allow the elastic strings to slip according to exercise, thereby preventing friction while keeping the elastic strings positioned at the lowest point, under the armpit. Therefore, when the user pulls out the handle 130, the tension applied to the elastic strings 120 extending forward or backward of the user's body may be evenly distributed.

[0086] At this time, the handle coupler 131 of the handle 130 is connected at the user's armpit which is around the middle of the elastic string 120, allowing the handle 130 to be positioned at the lowest point of the elastic string 120.

[0087] The upper part of the handle 130 is connected to the elastic string 120 via the handle coupler 131, and a waist string 140 is connected to the third connecting ring 132, which is provided at the lower part of the handle 130, via a waste coupler 141—as such, both the upper and lower part of the handle 130 are elastically connected.

[0088] The waist string 140, which is provided as a separate elastic string from the elastic string 120 and passes the rear (waist or butt) of the user, is connected to the third connecting rings 132 which are provided at lower parts of the left and right handles 130 on the user's body, so that the muscles in the front of the upper arm and in the front of the shoulder are strongly tensioned when the arm moves from a lower and rear position to an upper and front position. In other words, the handles 130 are coupled at both sides of the waist string 140 and the elastic strings 120, forming a second closed loop. According to the present invention, as the closed loop is formed without an opening between first sides of the handles 130 and the elastic strings 120, when extension and flexion (or forth-and-back movement) with respect to the elbow joint is repeated, the upper and lower parts and the front and rear of the arm are simultaneously tensioned, leading to movement of the arm when walking.

[0089] When the user moves his arm from the back to front to flex the elbow joint of the arm as shown in FIG. 9B, the waist string 140 is extended, producing tension and hence contracting biceps and deltoid and supraspinatus. When the user extends his arm from the front to back as shown in FIG. 9A, the elastic strings 120 inside the covering means 123 are extended to produce tension and hence contracting triceps. Such flexion and relaxation leads to movement of the user's arm as the user walks, thereby raising exercise effects.

[0090] The waist string 140 is formed of an elastic string with waist couplers 141 formed at both ends thereof and is positioned on the user's waist or butt.

[0091] The third connecting ring 132 may be formed of a closed triangular ring. The waist coupler 141 is formed of a plastic ring that may be open and closed to be hooked to or unhooked from the third connecting ring 132.

[0092] The waist ring 140 may be covered with a covering means, as are the elastic strings 120, to be prevented from friction.

[0093] The waist ring 140 may be inserted through the loops of the pants, allowing the wearable arm exerciser to be stably worn.

[0094] The handles 130 are coupled with the elastic strings 120 and the waist string 140, giving strong stimulation to the arms, and thus an exercise effect, when the user pulls the handles 130 from a rear to front position, from a front to rear position, from a lower to upper position, or from an upper to lower position. In other words, an exercise effect is achieved when the arm is moved backward, as well as forward, while walking.

[0095] When the handle 130 is moved down, the triceps may be strongly tensioned and, when the handle 130 is moved up, the biceps and deltoid may be strongly tensioned.

[0096] The handle 130 may include a rear part 130b and a front part 130a which is formed of a pad with a predetermined thickness and width and surrounding the back of the hand when the rear part 130b is grabbed by the user. The user's hand may be inserted between the front part 130a and the rear part 130b and may thus be stably placed.

[0097] Such a structure of the handle 130 allows the user to hang his hand on the handle 130 without tightly holding it when his arm feels fatigue. Thus, the user may relax and recover from fatigue.

[0098] In the wearable arm exerciser 100 usable while walking as described above, the user wears the wearable arm exerciser 100 by putting it on his shoulders, with the webbing belts 110 and the elastic strings 120 coupled together, adjusts the length to fit the user's body, and then holds, in his hands, the handles 130 coupled to both sides of the elastic strings 120, which are placed on the user's chest and under the armpits and alternately pulling the right and left handles 130 while walking to thereby do upper body exercise.

[0099] The armpits are depressed parts on the sides of the chest and under the shoulders, which contain lots of fat and a large sweat gland and lymph node group under the skin and where major nerves and blood vessels pass, and is susceptible to adhesion in such a disease as frozen shoulder and hard to exercise. However, exercise on the wearable arm exerciser 100 of the present invention may prompt lymph circulation at or around the armpits and increase the flexibility of the surrounding tissues.

[0100] On the other hand, as illustrated in FIG. 6, the anti-friction device 150 may be provided between the handle coupler 131 and the elastic strings 120 to generate the same amount of tension at the front and back of the strings by keeping the handle 130 positioned at the lowest point of the strings while reducing continuous friction between the handle coupler 131 and the elastic strings 120 due to changes in the position of the handle 130, The anti-friction device 150 includes a circular string support 153 that has a diameter large enough to enable wide line contact to reduce frictional wear of the elastic strings 120 and a handle fastener 151 which is coupled with the string support 153 and into which the handle coupler 131 is fitted.

[0101] The string support 153 includes a string moving part 154 that is recessed inward to allow the elastic strings 120 to be inserted therethrough and prevent the elastic strings 120 from escaping off, a string fixing part 154 surrounding the elastic strings to prevent the elastic strings 120 from escaping off, around the handle fastener 151, and stepped portions 157 where the elastic strings 120 are exposed at the ends of the string fixing part 154. The central portion of the string support 153 has a hollow central hole 156, so that the elastic strings 120 slip while making wide line contact in the string moving part 154. The string fixing part 154 has a groove formed in the outside thereof to allow the elastic strings 120 to be inserted therethrough.

[0102] The handle fastener 151 is shaped as a hollow circle or an ellipse and is coupled with the handle coupler 131. One hand fastener 151 may be provided on one side of the groove 152 in the string support 153 as illustrated in FIG. 7 or two hand fasteners 151 may be provided on both sides of the groove 152 in the string support 153 as illustrated in FIG. 8.

[0103] The elastic strings 120 are inserted into the anti-friction device 150, and when the handle 130 moves back and forth, the elastic strings 120 slip in the circular string fixing part 154 while making wide line contact. Therefore, continuous friction to any one portion of the elastic strings 120 may be prevented, allowing for long-term use of the elastic strings 120. The anti-friction device 150 which has a slipping function may allow the strings to slip during exercise, keeping the handle 130 positioned at the lowest point of the strings and hence allowing the same amount of tension to be distributed on the front and back strings of the user's body.

[0104] Further, the anti-friction device 150 may minimize friction between the elastic strings 120 and the handle coupler 131 while allowing the limited elasticity of the elastic strings to be used as efficient as possible. For example, if 100 g of tension is generated at the handle 130 when the front elastic strings are pulled by 1 cm, then 200 g of tension is generated if the front and back strings are simultaneously pulled by 1 cm, so that the load of exercise doubles.

[0105] Given the limited elasticity according to the length of the elastic strings 120, if the same amount of tension is generated at the front and back strings, the efficiency of exercise may be significantly increased.

[0106] As such, the present invention allows the user to work or move, with it worn, and allows the user to easily exercise anytime as long as he has a short break time.

[0107] Further, the present invention, by its excellent wearability and portability, allows the user to do exercise even when seated in the same way as he can in other positions. In particular, while standing or sitting, the user may do exercise on the wearable arm exerciser, with his left hand put in the right handle 130 or with his right hand put in the right handle 130. This way enables exercise in various directions and leads the user to exercise fitting the user's environment while stimulating various upper body muscles.

[0108] Thus, according to the present invention, a wearable arm exerciser 100 usable for walking includes, in its basic structure, webbing belts 110 passing from a user's chest through the user's shoulders and crossed in an X shape, one or more elastic strings 120 coupled, in front or behind, to the webbing belts 110, and handles 130 coupled with the elastic strings 120 to produce tension and further including a waist string 140 which is connected to the handles 130 to exercise triceps, wherein, as the elastic strings 120 and the waist string 140 are connected to the upper and lower parts, respectively, of the handles 130, the muscles around the shoulder joints may be tensioned by back-and-forth movement and upper-and-lower movement of the arm that arise when the shoulder joint moves while walking, thereby producing an exercise effect to reinforce the flexibility of shoulder muscles and preventing or relieving shoulder disease.

[0109] Further, in the wearable arm exerciser 100 usable while walking, according to the present invention, the user may exercise the triceps by pulling down the elastic strings 120 ahead of the shoulders and may also exercise biceps, deltoid, and supraspinatus that are used when the arm extends to move from a rear to front position or from a lower to upper position.

[0110] Further, in a wearable arm exerciser 100 usable while walking, according to the present invention, the connecting means are connected to the middles of the elastic strings 120, i.e., around the armpits so as to evenly distribute tension applied to the elastic strings 120 on the front and rear of the user's body when the handles 130 are pulled, and a separate elastic string, i.e., the waist string 140, is connected to the connecting rings 132 provided under the handles 130 to pass over the rear part (waist or butt) of the user's body to produce tension whose strength is adjustable in the muscles in the front parts of the upper arm and shoulder when the arm is moved from a rear to front position or from a lower to upper position, thereby increasing the exercise effect.

[0111] Further, a wearable arm exerciser 100 usable while walking may be easily produced in a simplified structure including webbing belts 110 crossed in an X shape on the user's back, elastic strings 120 coupled with the webbing belts 110, and handles 130 coupled to the elastic strings 120 and a waist string 140 connected to the handles 130, in which as the user couples the elastic strings 120 to the webbing belts 110 on the shoulders, wears the wearable arm exerciser 100, and repeatedly pulls the handles 130 while walking, the wearable arm exerciser 100 enables steady upper body exercise along with leg exercise.

[0112] Further, in a wearable arm exerciser 100 usable while walking, the structure of the wearable arm exerciser 100 in which the left and right elastic strings 120 are connected to the webbing belts 110 so that tension is delivered to the left elastic string 120 when the right handle 130 is pulled enables a natural, simultaneous, and balanced posing of the same load of exercise to both arms during the course of swinging the arm forward and backward, and after a predetermined degree of tension is formed by pulling down the handle 130, back-and-forth movement is performed, steadily delivering a predetermined degree or more of tension to the arms during the course of exercise and hence giving rise to increased physical endurance.

[0113] Further, according to the present invention, a wearable arm exerciser 100 usable while walking is formed of an elastic material to be tightly worn on the user's body so that it may be put on a dress suit or training suit, thus allowing the user to exercise during a spare time at work or commuting or taking a walk.

[0114] Further, in the wearable arm exerciser 100 usable while walking, both the handles 130 may be pulled in opposite directions, transferring tension to more muscles in a wider area.

[0115] Further, a wearable arm exerciser 100 usable while walking, according to the present invention, may be worn while walking or jogging to enable upper body (muscles around the arms and shoulders) exercise in a natural way and with the expectation of balanced development of upper and lower body muscles and the prevention or mitigation of various musculoskeletal diseases from the shoulders through the elbow joints to the wrists.

[0116] Further, according to the present invention, a wearable arm exerciser 100 usable while walking may be adjusted in length while being worn and be easy to wear or remove.

[0117] Further, in a wearable arm exerciser 100 usable while walking, the elastic strings 120 formed of one or more wires may be separated by the covering means 123, thereby preventing friction against the user's body and injury due to the elastic string 120 when disconnected.

[0118] Further, in a wearable arm exerciser 100 usable while walking, the strength of exercise may be adjusted by varying the thickness of the elastic strings 120 coupled to the webbing belts 110 or the number of the elastic strings 120.
