Abstract
Description
[Technical Field]
[0001] The present invention relates to a band-shaped member worn on the human body, such as a smartwatch band or a headband for headphones, and more particularly to a band-shaped member for human body wear that can be wrapped around or bent to be worn on the human body. [Background technology]
[0002] Bands for smartwatches and headbands for headphones, and other band-like components worn on the human body, are primarily made of plastic. However, in recent years, there has been a growing social demand to minimize the use of plastic. Paper is one example of a plastic substitute (see Patent Document 1, etc.). [Prior art documents] [Patent Documents]
[0003] [Patent Document 1] Japanese Patent Application Publication No. 02-310580 [Overview of the Initiative] [Problems that the invention aims to solve]
[0004] However, ordinary thin paper cannot provide the required strength and is prone to wrinkles, folds, and fraying. On the other hand, thick cardboard is too rigid to be wrapped around the human body or bent to conform to the body, making it difficult to use as a band-shaped component for human attachment. In view of these circumstances, the present invention aims to provide a strip-shaped member for human attachment, primarily made of paper, that can achieve both the required strength and ease of attachment to the human body. [Means for solving the problem]
[0005] To solve the above problems, the present invention provides a band-shaped member that is attached to the human body, It comprises a strip-shaped base material having a part that needs to be deformed, The aforementioned base material consists of cardboard with a thickness of 0.5 mm to 5 mm. The deformation-prone portion is characterized in that one or more notched grooves intersecting the longitudinal direction of the base material are formed so as to reach the longitudinal side edges on both sides in the width direction of the base material. With this strip-shaped member, the required strength of the base material can be ensured by making the thickness of the paper base material greater than that of ordinary paper. Furthermore, deformation is permitted in the parts that require deformation by the cut grooves. Therefore, the strip-shaped member can be wrapped around the human body or bent to fit the human body, ensuring wearability on the human body.
[0006] Preferably, the notched groove may be straight. This facilitates manufacturing. The aforementioned grooves may be wavy or meandering. This allows the base material to be deformed not only by bending but also by twisting. Preferably, the plurality of notches are arranged parallel to each other.
[0007] Preferably, the remaining thickness from the bottom of the groove in the substrate to the surface opposite the groove is 0.05 mm or more and less than the stated thickness. By setting the remaining thickness and, consequently, the depth of the groove, the degree of deformation, such as the curvature of the part to be deformed, can be adjusted.
[0008] The pitch of the aforementioned multiple cut grooves is 1 mm or more. The degree to which the deformation of the part to be deformed can be adjusted by setting the pitch. [Effects of the Invention]
[0009] According to the present invention, it is possible to achieve both the required strength and ease of attachment to the human body in a strip-shaped member for human attachment that is mainly made of paper. [Brief explanation of the drawing]

Mode for Carrying Out the Invention
[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. <First Embodiment (FIGS. 1 to 3)> As shown in FIG. 1, an applied product of the first embodiment of the present invention is a wristwatch-type device 1 such as a smartwatch. As shown in FIG. 1(a), the wristwatch-type device 1 has a device body 1a and a wristband 2. Base ends 3b of a pair of band portions 3 of the wristband 2 are attached to both ends of the device body 1a. Stopping portions 4 and 5 are provided at the tip ends of each band portion 3. As shown in FIG. 1(b), the wristwatch-type device 1 is wound around the arm A of the human body, and the stopping portions 4 and 5 are stopped to be worn on the human body. Although detailed illustration is omitted, the stopping portions 4 and 5 are constituted by a planar fastener, a button, a buckle, a key lock, etc.
[0012] As shown in FIG. 1(a), the pair of band portions 3 are each constituted by a belt-like member 10 for body wear. The belt-like member 10 for body wear includes a belt-like base material 11 as a main material. The longitudinal dimension of the base material 11 is several times to several hundred times the width dimension of the base material 11. The width dimension of the base material 11 is several times to several tens of times the thickness t 11 of the base material 11.
[0013] The material of the base material 11 is paper, preferably thick and hard cardboard. 11 is, t 11 = Approximately 0.5mm to 5mm, preferably t 11 The thickness is approximately 1 mm to 5 mm. This ensures the required strength of the body-worn band-shaped member 10. The paper constituting the base material 11 includes paper materials such as cellulose and pulp. Preferably, the paper constituting the base material 11 is made by pressing and compressing paper material to harden it, or by laminating and integrating multiple sheets of paper material with a thickness of several mm.
[0014] As shown in Figure 1(a), the majority of the base material 11, excluding both ends in the longitudinal direction, constitutes a deformable portion 19 that is to be allowed to bend. As shown in Figure 2, one or more notches 12 (half-cuts) are formed in the deformable portion 19. Preferably, a number of notches 12 are formed in the deformable portion 19 at a constant pitch P in the longitudinal direction. 12 It is formed by the pitch P of the notched groove 12. 12 Preferably P 12 = 1 mm or more and 10 mm or less, more preferably P 12 = Between 1mm and 5mm.
[0015] As shown in Figure 2, each notch 12 extends so as to intersect the longitudinal direction (left-right direction in Figure 2) of the base material 11. Both ends of the notch 12 reach the longitudinal side edges 15 on both sides (top and bottom in Figure 2) in the width direction of the base material 11. Preferably, the notch 12 is linear along the width direction (top and bottom direction in Figure 2) of the base material 11. Multiple linear notches 12 are arranged parallel to each other. Multiple curved notches 12 may also be arranged parallel to each other (see the third embodiment (Figure 6)).
[0016] As shown in Fig. 3(a), the cut groove 12 is formed in the thickness direction of the base material 11 from the outer peripheral side surface 13 to the inner peripheral side surface 14 of the base material 11. The outer peripheral side surface 13 is the surface facing the outside when the arm band 2 is wound around the arm. The inner peripheral side surface 14 is the surface contacting the arm when the arm band 2 is wound around the arm. The cut groove 12 does not reach the inner peripheral side surface 14 (the surface opposite to the cut groove). The remaining thickness ta from the groove bottom 12d of the cut groove 12 to the inner peripheral side surface 14 is preferably 0.05 mm or more and less than the thickness t 11 (0.05 mm ≦ ta < t 11 ).
[0017] According to the body-wearing belt-like member 10, by using paper as the main material, the amount of plastic used in the entire product 1 can be reduced. As shown in Fig. 3(b), when the arm band 2 made of the body-wearing belt-like member 10 is wound around the arm A (Fig. 1(a)), each cut groove 12 is expanded, and the required deformation part 19 is curved and deformed as a whole. As a result, the arm band 2 can be easily wound around the arm A and worn. On the other hand, as shown in Fig. 3(b), the solid part 11a of the base material 11 between adjacent cut grooves 12 is hard and difficult to deform. Therefore, the required strength of the body-wearing belt-like member 10 can be ensured, and the formation of wrinkles, breaks, abrasions, etc. on the body-wearing belt-like member 10 can be suppressed. As a result, it is possible to achieve both the required strength and the body-wearing property of the body-wearing belt-like member 10 made of the paper base material 11.
[0018] Next, another embodiment of the present invention will be described. In the following embodiments, for the configurations overlapping with the above-described embodiments, the same reference numerals are given in the drawings and the description will be omitted as appropriate. <Second Embodiment (Figs. 4 to 5)> As shown in Fig. 4, the applied product of the second embodiment of the present invention is the headphones 6. As shown in Fig. 4(a), the headphones 6 include a headband 7 and a pair of earcup speakers 8. The earcup speakers 8 are attached to both ends of the curved belt-like headband 7 via the connecting portions 9.
[0019] In the second embodiment, the headband 7 of the headphones 6 is made of a body-worn band member 10B. The body-worn band member 10B comprises a band-shaped base material 11B made of thick cardboard. As shown in Figure 5, the thickness t of the base material 11B 11B is, t 11B = Approximately 0.5mm to 5mm, preferably t 11B It is approximately 2mm to 5mm in size.
[0020] As shown in Figure 4(a), the base material 11B for the headphones 6 is curved in an unloaded state by being given a curvature during molding that matches the standard size of a human head. Deformable sections 19 are set at both ends of the curved base material 11B. Several shallow notches 12B (half-cuts) are formed on the inner circumferential surface of the deformable sections 19 on the base material 11B. This allows the curvature of the deformable sections 19 on the base material 11B to be finely adjusted to match the size of the head B of the actual user of the headphones 6, as shown in Figure 4(b).
[0021] As shown in Figure 5, the pitch P of the notched groove 12B 12B Preferably P 12B = 1 mm or more and 10 mm or less, more preferably P 12B = Between 1mm and 5mm. The remaining thickness tb from the bottom 12d of the groove 12B to the outer surface of the base material 11B is greater than the depth of the groove 12B. This gives the base material 11B rigidity (elasticity) even in the deformation-prone area 19, allowing the headphones 6 to be stably attached to the user's head B.
[0022] Furthermore, notches may be formed on the outer circumferential surface of the base material 11B. Notches may be formed on both the inner and outer circumferential surfaces of the base material 11B. The majority of the base material 11B in the longitudinal direction may be the deformable portion 19, and multiple notches may be provided over the entire longitudinal area of the base material 11B. The headband 7 may include multiple base materials connected in the longitudinal direction. The headband 7 may be expandable and contractible by the sliding of the multiple base materials relative to each other.
[0023] <Third Embodiment (Figure 6)> As shown in Figure 6, in the third embodiment of the present invention, the body-worn band member 10C has a wavy or meandering groove 12C (half-cut) in the cardboard base material 11C. The wave shape of the groove 12C is triangular wave or sinusoidal. This allows the body-worn band member 10C to be not only bent but also twisted. The wave shape of the notched groove 12C may also be a square wave shape or the like. The product to which the third embodiment applies may be a wristwatch-type device 1 (Figure 1) or headphones 6 (Figure 4).
[0024] The present invention is not limited to the embodiments described above, and various modifications can be made as long as they do not contradict its spirit. For example, the notched groove may be straight, wavy, or meandering, extending diagonally with respect to the width direction of the base material. The belt-shaped member for human body attachment may have holes formed for fasteners such as buckles, or for connecting to other parts or for punching. Holes may also be formed after the cut grooves have been formed. The band-shaped member for human body attachment may include a surface resin layer and a metal reinforcing layer in addition to the cardboard base material. This invention is not limited to wristwatch-type devices or headphone bands, but can also be applied to VR goggle bands, massage bands, and other band-shaped members worn on the human body.
