Summary of the Invention

Problems to be Solved by the Invention

[0004] However, according to the above - mentioned technology, for users with different body builds and dimensions on the left and right, or users with distorted skeletons, etc., there may be gaps in the chest and upper back, and an optimal fitting state may not be measurable. Also, although the shoulder belt is adjustable in length, there is no means to consider the area of the pad part with a buffering effect. Furthermore, it is impossible to create an optimal carrying state through the same path of the body for users with different body dimensions, and as a result, it was impossible to provide a measurement of a certain fitting quality for different users.

[Effects of the Invention]

[0006] According to the method of the present invention, starting with the bent portion of the roughly angled lower pad aligned with the armpit, the dimensions of the upper pad, lower pad, and back panel can be adjusted so that they uniformly conform to the body surface and make contact. This can be done regardless of differences in left and right body shape, and can also be adapted to users with different body dimensions and builds, creating an optimal carrying position through the same path on the body.

When the body shape changes, adjustments can be made based on the records, and the optimal fitting state can be easily updated. [Brief explanation of the drawing]

[0007] [Figure 1] This is an unfolded diagram showing the 13 dimensions defined in this invention. [Figure 2] This figure shows the measuring instrument of the present invention being worn by the person being measured. [Figure 3] This is a front view showing Embodiment 1 of the measuring instrument of the present invention. [Figure 4] This is a front view showing a part of the component in Figure 3. [Figure 5] This is a rear view showing a part of the component in Figure 3. [Modes for carrying out the invention]

[0008] Embodiments of the present invention will be described.

[0009] The measurement method of the present invention will be explained using Figures 1 and 2. The 13 dimensions that define the optimal carrying position measured by the method of the present invention are represented as shown in the unfolded view of Figure 1. That is, the upper part of the back panel 1 is connected to a pair of left and right shoulder pads 2, each having two bends on one side. The shoulder pads 2 consist of a lower pad 2a and an upper pad 2b, both having bends with a fixed angle in a roughly V-shape, and these are rotatably connected. The length of the center line extending from the center of the bend of the lower pad 2a to the lower end 2p is the lower pad length A. The length of the center line extending upward from the center of the bend of the lower pad 2a to the rotation center with respect to the upper pad 2b is the upper pad length B. The angle between the center line of the upper pad 2b and the upper center line of the lower pad 2a is the upper pad angle C.

[0010] The upper pad 2b is connected such that its centerline is parallel to the centerline of the back panel 1 in the height direction. The height from the reference point O of the back panel 1 to the end of the upper pad 2b is the pad base height D, and the horizontal distance between the centerline of the back panel 1 and the centerline of the upper pad 2b is the pad base distance E. In the unfolded diagram, the shoulder pad 2 and shoulder strap 3 are not connected, but in the actual carrying state as shown in Figure 2, the lower end 2p of the lower pad 2a and the end 3p of the shoulder strap are connected. The other end of the shoulder strap 3 is connected to the back panel 1, and the length from this connection point to the end 3p of the shoulder strap is the strap lower length F. Furthermore, the height dimension of the back panel 1 is the back panel height G. Of the above dimensions, the six dimensions A to F consist of one pair each on the left and right, and together with the back panel height G, there are a total of 13 dimensions.

[0011] In the optimal carrying position measured by the method of the present invention, the above 13 dimensions are the dimensions at the time of adjustment using the following adjustment method. Position the curved portion of the lower pad 2a along the axilla so that the orientation of the lower pad 2a is stably fixed to the outside of the chest. Then, adjust the lower pad length A so that the lower end portion 2p of the lower pad 2a is located in the area from the side of the chest to the lower rib and near the intermediate plane M between the front and back of the body. This ensures that the lower pad 2a covers the front of the body to the maximum extent. Furthermore, adjust the upper pad length B so that the upper side of the lower pad 2a follows the curved surface of the upper part of the scapula in front of and behind the ridge line R of the shoulder. Then, adjust the upper pad angle C so that the upper pad 2b remains in contact with the body, and adjust the pad base height D and pad base distance E while pulling the upper pad 2b. For the back panel 1, adjust the back panel height G so that it contacts the flat part of the upper back. Adjust the lower strap length F so that the upper pad 2b, lower pad 2a, and back panel 1 make gentle contact with the body. After following the above steps and adjusting the dimensions of the present invention, it will be carried on the back as shown in Figure 2.

[0012] An embodiment of the measuring instrument capable of stably measuring the 13 dimensions of the present invention and performing the above adjustment method will be described with reference to Figures 3 to 5.

[0013] The lower pad 2a has hook-and-loop fasteners 51 on its surface and has slit holes 6 at both its upper and lower ends. The upper extension member 21 and the lower extension member 22 are inserted through these slit holes 6 and can be extended while sliding vertically in the bending direction. On the back surface near the end of the upper extension member 21 and the lower extension member 22 on the lower pad 2a side, hook-and-loop fasteners 52 corresponding to the lower pad 2a are provided, allowing them to be fixed to the lower pad 2a at the desired extension position. A detachable resin buckle 7 is sewn to the other end of the lower extension member 22 via a woven tape 8, and a shoulder strap 3 is connected to the other end of the resin buckle in an adjustable length.

[0014] Near the other end of the upper extension member 21, it is pivotally supported on one end side of the upper pad 2b by a shaft extending in the thickness direction such as caulking, and a surface fastener 52 is provided at a portion overlapping the upper pad 2b. The upper pad 2b is provided with a surface fastener 51 corresponding to the surface fastener at a portion overlapping the upper extension member 22, and they can be fixed to each other at a preferred rotation angle. Further, a surface fastener 52 is also provided on the other end side of the upper pad 2b, and it can be fixed to the corresponding surface fastener 51 portion of the upper part 1a of the back plate material.

[0015] The back plate material 1 is composed of an upper part 1a and a lower part 1b. The lower part 1b has a slit hole 6, and the height adjustment part 11 of the upper part 1a is inserted therethrough. A surface fastener 52 is provided on the height adjustment part 11, and a corresponding surface fastener 51 is also provided on the lower part 1b, so that the back plate material 1 can be adjusted to a preferred height and then fixed. In addition, in order to fix the position of the lower part 1b at the waist of the person being measured, a hip belt 9 made of woven tape is sewn. The hip belt 9 is loop-shaped with a resin buckle 7 that can be adjusted in length and is detachable.

[0016] The relationship between the insertion part corresponding to the slit hole 6 of the embodiment of the measuring instrument is just one example, and it may be provided on the opposite member. Also, since it is a measuring instrument, a scale r and a reference mark m may be provided to read the length and angle at a glance. However, since the resin buckle 7 provided on the lower extension member and the hip belt can be removed respectively and the measuring instrument can be unfolded while maintaining the dimensional fixed state of each part, the dimensions may be directly measured using a ruler or a measuring tape in a stationary state.
