[Technical field]

[0001] The present invention relates to an exercise machine, and more particularly to an exercise machine having an elastic body and usable by patients who need rehabilitation. [Background technology]

[0002] Patients who have difficulty moving while lying in bed, such as seriously ill patients, use bed exercisers. For example, such patients use balls made of soft materials such as sponge or rubber, or elastic bodies such as rubber bands, as bed exercisers.

[0003] However, balls are difficult for patients who are not in good physical condition to handle, and because of their small size, there is a high risk that the patient will lose them while using them. In addition, rubber bands are attached to beds, etc., and resistance is concentrated at the attachment point, making them easily ripped. In particular, rubber bands are troublesome in that they must be attached anew every time they are used and then untied after use. Rubber bands must be fixed in various positions so that patients can exercise with various movements, but such inconveniences limit the use of rubber bands.

[0004] Such prior art is technical information that the inventor possessed for the purpose of deriving the present invention or that was acquired in the process of deriving the present invention, and is not necessarily publicly known art that was disclosed to the general public prior to the filing of the application for the present invention.

[0032] 1 and 2 illustrate exercise device 10 according to one embodiment of the present invention, FIG. 3 illustrates ball 200 according to one embodiment of the present invention, FIG. 4 illustrates opening 130 according to one embodiment of the present invention, and FIG. 5 shows ball 200 according to one embodiment of the present invention being inserted and removed through opening 130.

[0033] 1 to 5, the exercise device 10 according to an embodiment of the present invention can be used by a patient who needs rehabilitation in bed. For example, a patient who needs rehabilitation exercise but has difficulty leaving the bed, such as a seriously ill patient, can use the exercise device 10 according to an embodiment of the present invention to perform rehabilitation exercise. However, the exercise device 10 according to an embodiment of the present invention is not limited to rehabilitation exercise, and can be used for various movements and exercises such as muscle strength exercise, corrective exercise, and stretching.

[0034] 1-5, an exercise device 10 according to one embodiment of the present invention also includes an elastic band 100 and a ball 200. As shown in FIG.

[0035] The elastic band 100 is a band made of an elastic material such as rubber, and can be contracted and stretched in various directions, including the lengthwise direction and the widthwise direction. A user can perform resistance exercise by contracting and stretching the elastic band 100 while holding it with hands, feet, etc.

[0036] In one embodiment, the elastic band 100 also includes a body portion 110, a hook portion 120, and an opening .

[0037] 1 and 2, the body portion 110 extends longitudinally along the length of the elastic band 100. The body portion 110 may have a constant or varying width along the length.

[0038] The hanging part 120 is disposed at an end of the main body part 110 and supports the ball 200. For example, as shown in Figs. 1 and 2, the hanging part 120 may be disposed at each end of the main body part 110 in the longitudinal direction, and may have a ring or loop shape. The hanging part 120 forms a closed loop and is connected to the ball 200 to prevent the ball 200 from moving away from a designated position. For example, the ball 200 may be fixed to one side of the hanging part 120 or may move within the hanging part 120. Through this, a user can easily contract and stretch the elastic band 100 while holding the ball 200.

[0039] In one embodiment, the hanging part 120 may be inserted into the through-hole 210 of the ball 200, and one side of the hanging part 120 may be fixed to the through-hole 210. For example, an adhesive may be applied to the inside of the through-hole 210, and the hanging part 120 may be inserted through the through-hole 210, and one side of the hanging part 120 may be fixed to the inside of the through-hole 210 to which the adhesive is applied. As a result, a fixing region 121, which is a portion of the hanging part 120 inserted into the through-hole 210, may be fixed to the through-hole 210. Alternatively, the through-hole 210 may fix the hanging part 120, more specifically, the fixing region 121, to the through-hole 210 via a separate clamping member.

[0040] In other embodiments, the barb 120 does not include a means for securing the ball 200. That is, the ball 200 is inserted through the barb 120 and does not disengage from the barb 120, but is free to move along the barb 120.

[0041] In one embodiment, the hook portion 120 may be formed by joining one end of the elastic band 100 to the inside of the elastic band 100. For example, as shown in FIG. 2, one end of the main body portion 110 may be bent and joined to an inner portion of the main body portion 110, which may form the joining portion 140.

[0042] In one embodiment, the hanging portion 120 may be made of the same or a different material than the body portion 110 .

[0043] One or more openings 130 may be provided on one side of the elastic band 100, for example, on one side of the body 110. The openings 130 are spaced apart from the hook 120, and the ball 200 may be inserted or removed through the openings 130.

[0044] In one embodiment, one or more openings 130 may be disposed between a pair of hooks 120. For example, two openings 130 may be disposed adjacent to each of the pair of hooks 120. A user may adjust the tension by inserting a ball 200 disposed at an end of the elastic band 100 into or removing the ball 200 from the opening 130 to adjust the length of the elastic band 100.

[0045] For example, when the user wishes to contract and stretch the elastic band 100 with stronger tension in order to increase the intensity of exercise, the user can insert the ball 200 into the opening 130 and then pull it in the longitudinal direction to shorten the overall length of the elastic band 100. When the user wishes to contract and stretch the elastic band 100 with weaker tension in order to end exercise or reduce the intensity of exercise, the user can further remove the ball 200 from the opening 130 to lengthen the overall length of the elastic band 100.

[0046] In one embodiment, three or more openings 130 may be provided. For example, as shown in FIG. 5, three or more openings 130 may be provided between a pair of hanging parts 120. The openings 130 may be spaced apart from each other at equal intervals or at different intervals. Since the length of the elastic band 100 decreases as the distance between the opening 130 into which the ball 200 is inserted and the hanging part 120 increases, the user may select the opening 130 into which the ball 200 is inserted from among the multiple openings 130 and appropriately adjust the tension of the elastic band 100.

[0047] Through such a configuration, a user may conveniently adjust the tension of the elastic band 100 while inserting or removing the ball 200 through the opening 130 .

[0048] In one embodiment, the opening 130 may be disposed on the inside in the longitudinal direction of the elastic band 100 relative to the joint portion 140. In other words, the opening 130 may be disposed on the inside of the main body portion 110 so as not to overlap with the area where the hook portion 120 is formed.

[0049] In one embodiment, the opening 130 also includes a first slit 131 and a lamination member 133 .

[0050] The first slit 131 is a slit formed on one side of the body part 110 of the elastic band 100, and may be formed to extend long in the lengthwise direction and / or widthwise direction of the elastic band 100. For example, the first slit 131 may be elongated and slender, penetrating the body part 110 and extending along the lengthwise direction of the body part 110. As a result, when the ball 200 fixed to the hook part 120 passes through the first slit 131 and is pulled in the lengthwise direction of the elastic band 100, the body part 110 is hooked on the end of the first slit 131 and fixed.

[0051] 4, the first slit 131 is shown to have a rectangular or cuboid shape, but is not limited thereto, For example, the first slit 131 may also have a circular, elliptical, or other polygonal shape.

[0052] The adhesive member 133 may be disposed on one side of the body 110. For example, as shown in FIG 4, the adhesive member 133 may be disposed on the outside of the body 110 to correspond to the first slit 131. The adhesive member 133 may be made of a material that is stronger and has less or no elasticity than the body 110. This prevents the first slit 131 from being excessively opened or damaged when the ball 200 passes through the first slit 131.

[0053] 4 illustrates only the case where the bonding material 133 is disposed on the outside of the main body portion 110, but is not limited thereto. For example, the bonding material 133 may be disposed on the inside of the main body portion 110, or may be disposed both on the outside and inside.

[0054] In one embodiment, the bonding member 133 may have a second slit 132 corresponding to the first slit 131. The second slit 132 is disposed inside the bonding member 133 and may have the same or similar size and shape as the first slit 131. The ball 200 may pass through the first slit 131 and the second slit 132 in sequence.

[0055] In one embodiment, the bonding member 133 may be adhered to the body portion 110 by a pressing method. For example, the outer side of the bonding member 133, i.e., the remaining portion excluding the second slit 132, may be press-adhered to one surface of the body portion 110.

[0056] The reinforcing member 134 is disposed around the first slit 131 and / or the second slit 132 to prevent the first slit 131 and / or the second slit 132 from being damaged in the process of the ball 200 passing through. For example, as shown in Fig. 4, the reinforcing member 134 may be disposed with a predetermined width and thickness along the edges of the first slit 131 and the second slit 132. The type of the reinforcing member 134 is not particularly limited, and may be made of a material having a higher strength and less elasticity than the main body 110 and the bonding member 133.

[0057] The reinforcing member 134 may be arranged so as to be continuous or discontinuous along the inner edge of the first slit 131 or the inner edge of the second slit 132. Alternatively, the reinforcing member 134 may be arranged on both the main body 110 and the lamination member 133. For example, the reinforcing member 134 may be a thread sewn through the edges of the first slit 131 and the second slit 132. This allows the lamination member 133 to be more firmly fixed to the main body 110, and prevents the first slit 131 and the second slit 132 from being damaged by the ball 200.

[0058] One or more balls 200 may be provided at the ends of the elastic band 100. For example, as shown in Fig. 1, one ball 200 is provided at each end of the elastic band 100 in the longitudinal direction, and the user can perform exercises by holding and pulling the balls 200 with their hands. Alternatively, the user can use the balls 200 to secure the exercise device 10 to a bed railing or the like.

[0059] In one embodiment, the ball 200 may be disposed in the hanging portion 120. As shown in Figures 1 and 2, the ball 200 may be disposed in each of the hanging portions 120 provided on both ends of the elastic band 100. The hanging portion 120 passing through the ball 200 is joined to the elastic band 100 at the joint portion 140 to form a closed loop, and the ball 200 may be maintained in the hanging portion 120.

[0060] The ball 200 may have a through-hole 210 on one side into which the hanging part 120 is inserted. The through-hole 210 is a hole or slit formed on one side of the ball 200 and may be large enough for the elastic band 100 to pass through. In FIG. 3, the through-hole 210 is shown spaced apart from the center of the ball 200, but is not limited thereto. The through-hole 210 may be formed to include the center of the ball 200 or to be spaced apart from the center of the ball 200.

[0061] In one embodiment, the hook portion 120 may be fixed to one side of the through-hole 210. For example, as shown in Fig. 2 and Fig. 3, the through-hole 210 may have a flat surface toward the center of the ball 200 and / or a flat surface away from the center of the ball 200. An adhesive or the like may be applied to these surfaces, and the hook portion 120, more specifically, the fixing region 121, may be inserted into the through-hole 210 and then adhered to the surface to be fixed.

[0062] In another embodiment, a mechanical configuration for fixing the hanging part 120 may be provided on one side of the through-hole 210. For example, as a fixing member, protrusions extending inwardly may be provided on both edges of one side of the through-hole 210, and the hanging part 120 may slide in a state of being inserted into the protrusions.

[0063] In another embodiment, the penetrating portion 210 does not fix the hanging portion 120. As a result, the ball 200 can move freely while being inserted into the hanging portion 120.

[0064] 6 and 7 show an exercise device 10A according to another embodiment of the present invention.

[0065] 6 and 7 is different from the exercise equipment 10 according to the above embodiment in the configuration of the ball 200A, but the remaining configuration is the same as that of the exercise equipment 10. For ease of explanation, the following description will focus on the configurations that are different from the exercise equipment 10.

[0066] The exercise equipment 10A according to one embodiment of the present invention includes an elastic band 100A and a ball 200A. The elastic band 100A also includes a main body portion 110A, a hook portion 120A, an opening portion 130A, and a joint portion 140A. These components are the same as those of the exercise equipment 10 according to the previous embodiment, and detailed description thereof will be omitted.

[0067] The ball 200A also includes a penetrating portion 210A and a fixed portion 220A.

[0068] The through-hole 210A is disposed so as to include the center of the ball 200A, and may have a circular, elliptical, or polygonal shape when viewed from the front. In FIG. 6, the through-hole 210A is illustrated as communicating one side and the other side of the ball 200A, but is not limited thereto. For example, the through-hole 210A may be formed in a concave shape through one side of the ball 200A into which the hanging portion 120A is inserted, and may be formed so as not to communicate with the other side of the ball 200A.

[0069] The fixing portion 220A is disposed inside the through-hole 210A and can fix the hook portion 120A. For example, the fixing portion 220A is disposed so as to connect the inner surfaces of both sides of the through-hole 210A, and the hook portion 120A is hooked on the fixing portion 220A to prevent the ball 200A from being detached from the elastic band 100A.

[0070] 6, the fixing part 220A is illustrated as being cylindrical, but is not limited thereto. For example, the fixing part 220A may have a shape with a different diameter along the height direction by repeatedly arranging recesses and protrusions on the outer surface. Alternatively, the fixing part 220A may be a polygonal prism.

[0071] In one embodiment, an adhesive may be applied to an outer surface of the fixed part 220A, and the hanging part 120A may be adhesively fixed to the fixed part 220A. Alternatively, no separate adhesive may be applied to the outer surface of the fixed part 220A, and the hanging part 120A may rotate while being wound around the fixed part 220A.

[0072] In another embodiment, the hook 120A may be disposed along the circumferential direction of the fixed part 220A. For example, as shown in FIG. 7, the hook 120A may be inserted through the through-hole 210A, and then may pass through the through-hole 210A after wrapping around the fixed part 220A one or more times. Here, the through-hole 210A is formed to communicate one side and the other side of the ball 200A, so that the hook 120A may be inserted into one side of the through-hole 210A, wrap around the fixed part 220A, and then pass through the other side. Alternatively, the through-hole 210A is formed to be recessed into one side of the ball 200A, so that the hook 120A may be inserted into one side of the through-hole 210A, wrap around the fixed part 220A, and then exit to the outside of the ball 200A through the first inserted side of the through-hole 210A. Through this, the hook 120A may be fixed in position to the fixed part 220A.

[0073] With such a configuration, the exercise device 10 according to an embodiment of the present invention allows even bedridden patients to easily exercise. In particular, the exercise device 10 according to an embodiment of the present invention uses the elastic band 100 and the ball 200, and the tension of the elastic band 100 can be easily adjusted to fix the exercise device 10 in an appropriate position.
