Description

[Technical Field]

[0001] The present invention relates to a hanger for suspending a sling seat. [Background technology]

[0002] When performing walking training for rehabilitation purposes, such as during the recovery period from a stroke or a leg injury, it is often difficult for patients to support their own weight due to a lack of strength in their legs. In such cases, if the weight on the legs could be reduced (load-relieved), walking training would become easier, and therefore there is a demand for equipment that allows for weight-relieving walking training.

[0003] Furthermore, when a person walks, weight is transferred between the left and right feet so that each foot alternates between the stance leg and the swing leg. Therefore, there is a need for equipment that can provide appropriate weight relief in response to the weight transfer between the two feet.

[0004] Therefore, the applicant of the present application previously proposed a hanger for hanging a sling sheet as a device that meets the above-mentioned needs, as described in Patent Document 1. This hanger for hanging a sling sheet comprises a main body, a torsion coil spring supported by the main body, a pair of arms extending left and right from both ends of the torsion coil spring, and a hanging part provided on each of the pair of arms on which the sling sheet is hung. As the load applied by the sling sheet changes, the pair of arms change their relative angle with each other, adjusting to prevent excessive load on the standing leg and also adjusting the left and right balance.

[0005] This sling sheet hanging hanger also has a display mechanism that indicates the magnitude of the load. However, this display mechanism is simply a linear scale on the main body that indicates the magnitude of the load based on the extension position of the arm extending from the main body, making it difficult to grasp the magnitude of the load being relieved.

DETAILED DESCRIPTION OF THE INVENTION

[0012] (1) Main body The structure of the main body is not particularly limited, as long as it can support the torsion coil spring and can be provided with a linear scale and numeric display.

[0013] (2) Torsion coil spring and arm The torsion coil spring may have any configuration, but examples include a configuration in which both ends of the torsion coil spring are arm portions, and the torsion coil spring and the arm portions are integrated, and a configuration in which both ends of the torsion coil spring are attached to arm portions, and the torsion coil spring and the arm portions are separate bodies.

[0014] (3) Linear scale and numerical display The linear scale preferably includes a plurality of linear segments corresponding to the extension positions of the arm portion that rotates in response to a change in the load. The numeral indication may be provided near each line segment of the linear scale, or may be provided near some of the line segments of the linear scale. The numerical indication may be a number that directly indicates the load value (kg force or N), or a number that indicates the relative magnitude of the load (without directly indicating the load value). The numbers in the numerical display are not particularly limited, but examples include Arabic numerals, Roman numerals, and Chinese numerals. [Example]

[0015] The present invention will be described with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor device according to an embodiment of the present invention; FIG. 2 is a block diagram of a semiconductor device according to an embodiment of the present invention; FIG. 3 is a block diagram of a semiconductor device according to an embodiment of the present invention;

[0016] As shown in Figures 1 and 2, the embodiment of the sling sheet hanging hanger 20 comprises a main body 21, a torsion coil spring 30 supported by the main body 21, a pair of arm portions 32 extending left and right from both ends of the torsion coil spring 30, and a hanging portion 33 provided on each of the pair of arm portions 32 on which a sling sheet (described later) is hung, and the pair of arm portions 32 change their relative angle with respect to each other as the load applied from the sling sheet changes.

[0017] The main body 21 includes a substantially plate-shaped front plate 22, a substantially plate-shaped rear plate 24, and a substantially cylindrical support shaft 23 between the substantially central portions of the two plates 22, 24.

[0018] The torsion coil spring 30 is made by winding a spring steel wire in a spiral shape 2 to 5 times, and is supported by being fitted onto the support shaft 23 .

[0019] Arm portions 32 are formed integrally with both ends of torsion coil spring 30, extend in the tangential direction of torsion coil spring 30, and further extend from main body portion 21. A hook-shaped hanging portion 33 is formed at the tip of arm portion 32, and a strap of the sling seat (described later) is hung on hanging portion 33 so as not to shift position or fall off.

[0020] The sling sheet hanging hanger 20 is equipped with a display mechanism that indicates the magnitude of the load, and the display mechanism includes a linear scale 25 and a numerical display 26 using numbers, which are provided on the front surface of the front plate 22 of the main body 21 (or the rear surface of the rear plate 24) so ​​as to indicate the magnitude of the load depending on the extension position of the arm portion 32 extending from the main body 21.

[0021] 1, when the strap 17 is not hung on the hanging portion 33, that is, when the arm portion 32 is in an unloaded state where the load from the sling seat 16 is not applied to the arm portion 32, as viewed from the front, the pair of arm portions 32 extend substantially horizontally from the main body portion 21. Then, as shown by the two-dot chain line in FIG. 1, when the strap 17 is hung on the hanging portion 33 and the load from the strap 17 increases (the load relief increases), the torsion coil spring 30 deforms, the relative angle between the pair of arm portions 32 changes, and the extension position of the arm portion 32 from the main body portion 21 rotates downward.

[0022] The linear scale 25 includes a plurality of line segments corresponding to the extension position of the arm portion 32, which rotates in response to changes in the load. In the illustrated example, the line segments are provided corresponding to rotational movements of every 10 degrees. Furthermore, the numerical displays 26 in the illustrated example are provided near each line segment of the linear scale 25, and are Arabic numerals ranging from 0 to 5 that indicate the relative magnitude of the load (rather than directly indicating the numerical value of the load (kgf or N)).

[0023] [Usage example 1] The sling sheet hanging hanger 20 can be used for walking training, as shown in Figure 3. That is, the sling sheet hanging hanger 20 is attached to the lower end of the hoisting strap 13 of an electric hoist 12 that can move along rails 11 provided on the ceiling 10, and a pair of straps 17 of a sling sheet 16 worn by a walking training person P so as to cover the person's waist, buttocks, and part of the thighs is hung on the hanging parts 33 of the arms 32. The electric hoist 12 retracts the hoisting strap 13 to lift up the sling sheet 16, allowing walking training to be performed while relieving the burden on the walking training person P's legs. The following effects are obtained.

[0024] (a) Since straps 17 are attached to the left and right arm portions 32, respectively, the torsion coil spring 30 adjusts the load on the left and right in response to the shift in weight between the left and right feet during walking training, thereby providing appropriate load relief and preventing excessive load from being placed on the standing leg. (i) By providing the torsion coil spring 30, stable and appropriate load relief can be achieved. (c) By providing the torsion coil spring 30, the foot can smoothly respond to weight shifts during walking, allowing for natural walking. (d) The torsion coil spring 30 can be used to adjust the difference in length between the left and right straps, making it easy to adjust the balance between the left and right straps.

[0025] (E) A display mechanism is provided to show the magnitude of the load, and the display mechanism includes a linear scale 25 and a numeric display 26, making it easy to grasp the magnitude of the load being relieved. This provides the following detailed effects. -The amount of care can be quantified. · It becomes easier to record medical records and hand over information between staff members. - The amount of unloading can be adjusted to the same conditions every time. - By managing your numbers, you can track your recovery. - It also makes it easier to explain to patients. - More precise weight-bearing rehabilitation tailored to the patient's symptoms can be provided.

[0026] [Usage example 2] The sling sheet hanging hanger 20 can also be used for walking training, as shown in Figure 4. That is, the sling sheet hanging hanger 20 is attached to the lower end of the hoisting band 43 of an electric hoist 42 provided at the top of a gate-shaped steel frame 41, and as in Use Example 1, the pair of straps 17 of the sling sheet 16 worn by the walking training person P are hung on the hanging portions 33 of the arm portions 32, and the hoisting band 43 is wound up by the electric hoist 42 to lift up the sling sheet 16, thereby enabling walking training while relieving the burden on the feet of the walking training person P. This provides the same effects as Use Example 1.

[0027] The present invention is not limited to the above-described embodiments, and can be embodied by making appropriate modifications within the scope of the invention. [Explanation of symbols]
