Description

  The present invention relates to a shock absorbing buffer structure used for absorbing a shock received by a body due to a fall and protecting the body, and a hip protector provided with the buffer structure, particularly for a fall of an elderly person. It relates to what is used to prevent the occurrence of fractures caused by it.

  With the progress toward an aging society, fractures (fall fractures) associated with the fall of elderly people are increasing. Since many of these fall fractures are fractures of the femoral neck, it has been proposed to wear a hip protector so that the impact can be absorbed even if the fall occurs (see Patent Document 1, for example). . This is a hip protector constructed by detachably attaching a shock absorbing pad to a long pant as an underwear. The shock absorbing pad has a plate-like shape having elasticity formed of a foamed polyurethane elastomer. A laminated structure of an outer portion, a fabric sheet embedded in the inner surface and functioning as a core, and a soft inner portion formed of a soft low-resilience polyurethane foam is employed. This is intended to protect the wearer's body by receiving an external impact at the time of falling at the outer portion and buffering the impact force at the inner portion.

  Further, a hip protector intended for diaper-type pants using a hook-and-loop fastener is also known in which an impact absorbing pad is detachably mounted (see, for example, Patent Document 2). This shock absorbing pad is intended to improve the feeling of contact with the body while ensuring a desired hardness by forming it in a dome shape using ABS resin as a core material.

  Furthermore, various types of hip protectors for sports have been proposed for protecting the body by absorbing the impact received by the body (see, for example, Patent Document 3). In Patent Document 3, in order to cover the entire surface of the half-length pants as sportswear with an impact absorbing member, the impact absorbing member is divided into a number of divided parts, and the divided parts are often arranged along the curved surface of the body. It has a unique shape.

  However, in the above hip protector, there is a tendency to force the wearer to operate under an adverse environment of being heavy, hard, and bulky, and it is possible to encourage aggressive wearing and sufficiently promote wearing. I can't. For sports use, it is only worn during competitions, and since the wearer wants to wear it most of the time, it tends to be worn more aggressively. On the other hand, even if it is recommended to wear to prevent falling fractures, it is considered that the promotion of wearing is quite difficult due to the above circumstances. In particular, since the various pads described above use a synthetic resin as a shock-absorbing buffer, it is unavoidable that the air permeability is inferior in addition to the adverse environment of heavy, hard, and bulky. They thought. In addition to the above-mentioned adverse environment, it is necessary to hold the shock-absorbing pad in a predetermined position on the body, particularly in the underwear type as clothes (wearing items) to which such shock-absorbing shock absorbers are applied. It is designed to fit the body relatively tightly against the body, so it is tighter than normal underwear and takes time to attach and detach, especially at nighttime when there is a high risk of falling fractures There are also inconveniences such as difficulty in attaching and detaching during a flight. For this reason, the promotion of wearing by elderly people does not progress easily, and it is considered that it cannot be an effective measure against an increase in falling fractures.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a shock absorbing shock absorber that can eliminate conventional disadvantages as much as possible, and to use this shock absorber. It is to provide a hip protector that can promote wearing for preventing a fall fracture of a person.

  In order to achieve the above object, according to the first aspect of the present invention, as a shock absorbing structure for absorbing shock, a large number of thin cylindrical structural walls arranged parallel to each other with the cylinder axis facing in the thickness direction are flattened. A unit buffer formed integrally in a block shape is used, and one or more desired number of unit buffers are applied to the outer region to be protected so as to receive an impact force in the thickness direction. It is assumed that they are arranged together (claim 1). The above “cylindrical shape” is intended to include a cylinder having an elliptical or oval cross-sectional shape in addition to a perfect circle. Further, as the cylindrical structure wall, a paper tube piece or a synthetic resin tube piece can be used. Further, “many” means not a few, but more than that.

  In the case of the present invention, the unit buffer is disposed so as to receive an impact force in the thickness direction, that is, in the cylinder axis direction of each cylindrical structure wall, and in the thickness direction, from the opening end face of each cylindrical structure wall. A thin cylindrical wall and a gap between the cylindrical walls extend. In other words, a frame structure wall is composed of a thin cylindrical wall, which is a large number of cylindrical structure walls, and when an impact force is received from the opening end face side, the frame structure wall is buckled and crushed to reduce the impact force. While absorbing, an efficient buffer function of blocking the transmission of the impact force to the rear is exhibited. Further, this unit buffer is constituted by a thin cylindrical structure wall, and the remaining part is a gap, so that it is lightweight and not hard as compared with a hard synthetic resin. Further, since the shock absorbing function is exhibited by crushing the above-described frame structure wall, an impact force that is received at the time of falling can be absorbed without being thickened and the transmission can be cut off. Therefore, it is possible to provide a buffer structure applied to a hip protector or the like that eliminates the conventional inconvenience of being heavy, hard and bulky.

  The unit buffer in the present invention may be provided with a thin substrate integrated so as to cover at least one open end face of the many thin cylindrical structural walls. . By disposing the unit buffer on the front side where the impact force is applied and disposing the unit buffer, the impact force can be uniformly distributed and transmitted to each cylindrical structure wall behind. The entire cylindrical structure wall can absorb the impact force efficiently.

  The buffer structure according to the present invention may further include one or two or more housing portions that are provided in the outer region of the protection target and in which the unit buffer body is detachably housed (Claim 3). . By doing so, it is convenient to arrange the unit buffer along the outer region to be protected. That is, it can be easily disposed by sewing, adhering, or temporarily fixing the accommodating portion in a state where the unit buffer is accommodated, and the outer region to be protected is Even if it is constituted by a curved surface, the unit buffer is accommodated by being separated by each accommodating portion, so that it can be easily arranged along the curved surface.

  Moreover, in the invention which concerns on Claim 4, when the hip protector main body is worn with respect to the hip protector main body with the buffer structure in any one of said Claims 1-3 as a hip protector. It was decided to provide directly or indirectly so that the waist outer region of the wearer would be covered.

  In the case of the invention according to claim 4, by wearing the hip protector, the outer region of the waist of the wearer is covered with the above-described buffer structure. Even if an impact force is applied to the area, the impact force is surely exerted by the shock absorbing function by the collapse of the frame structure wall that the thin wall such as the inner lining and liner constituting the unit buffer body is crushed. And the transmission of impact force to the wearer's waist is also blocked. As a result, it is possible to effectively prevent a fall fracture and to eliminate the conventional inconvenience of being heavy, hard, and bulky, so that particularly elderly people can be promoted to wear.

  In the invention of claim 4, the hip protector body is constituted by trousers (invention 5), constituted by a stall (invention 6), or constituted by a waist pouch (invention 7). Can do. In other words, as a hip protector, it can be formed into a pants shape, a stall shape, or a waist pouch shape. By doing in this way, unlike the case of the conventional underwear type, the motivation to wear based on each function is obtained, thereby promoting the wearing.

  As described above, according to the buffer structure of any one of claims 1 to 3, a thin frame structure wall can be formed by a large number of cylindrical structure walls constituting the unit buffer, When an impact force is applied in the thickness direction, the frame structure wall buckles and is crushed and absorbs the impact force, while exhibiting an efficient buffer function that blocks the transmission of the impact force to the rear. Will be able to. Moreover, the conventional inconvenience of being heavy, hard and bulky can be eliminated as a buffer structure applied to a hip protector or the like.

  In particular, according to claim 2, by disposing the unit buffer with the substrate positioned on the front side where the impact force acts, the impact force is uniformly distributed to each cylindrical structural wall behind. Therefore, the impact force can be efficiently absorbed by the entire cylindrical structure wall behind. According to the third aspect, it is possible to easily and surely arrange the unit buffer along the outer region to be protected.

  Moreover, according to the hip protector provided with the buffer structure according to claims 4 to 7, even if the wearer of the hip protector falls down and the impact force is applied to the outer region of the waist, the impact force The shock absorbing function based on the crushing of the frame structure wall that the thin wall such as the shin and liner constituting the unit buffer body is crushed is surely absorbed, and the transmission of the impact force to the wearer's waist is ensured It can be blocked. Thereby, a fall fracture can be prevented effectively. In addition, since the conventional inconvenience of being heavy, hard, and bulky is eliminated, it is possible to promote the wear of the elderly and avoid the occurrence of the broken fracture of the elderly.

  In particular, according to any one of claims 5 to 7, since the hip protector body is composed of trousers, a stall, or a waist pouch, it is different from the conventional underwear type and is intended to be worn based on each function. Motivation to do so can be given, and further wearing promotion can be promoted.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 shows a unit buffer constituting the shock absorbing buffer structure according to the first embodiment of the present invention. The unit buffer 2 is formed in a flat block shape having a rectangular shape (for example, a square shape) in plan view, and has a large number of cylindrical structures extending in the plane direction (the paper surface direction in FIG. 2A) as shown in FIG. A thin-walled frame structure wall configured such that a wall and a gap between the structure walls extend in the thickness direction, and the frame structure wall is formed in a thickness direction (a direction perpendicular to the paper surface of FIG. 2A). A shock absorption margin of a predetermined thickness is provided so as to absorb the shock by crushing.

  Specifically, the unit buffer 2 is formed as a rectangular flat block (for example, a flat block having a length of 3.5 cm, a width of 3.5 cm, and a thickness of 1 cm) in plan view. As will be described later, the vertical and horizontal sizes of the unit cushions 2 are the outer regions around the base of the thighbone at the waist of the body where the cushioning structure is to be placed (the femur). The region covering the greater trochanter part of the body buffer) is set so as to be able to cover substantially along the curved surface and does not interfere with the movement of the body waist and the like. It is set so as to be able to absorb the impact force received at the time of falling by being crushed by receiving an impact in the thickness direction. The impact force may be set based on the acceleration when the target elderly person falls due to carelessness, shaking, and the weight of the elderly person. As an example of a desirable size, the size of the vertical (X) × horizontal (Y) is a square or a rectangle selected from 3 cm to 5 cm × 3 cm to 5 cm, and the unit buffer 2 is a straw 3 described later. The thickness (H) is 0.5 cm to 1.5 cm in the case of using a straw piece 51 using the above. If H is smaller than 0.5 cm, the shock absorbing function will be insufficient. Conversely, if H becomes thicker than 1.5 cm, the shock absorbing function will increase and excessive performance will be achieved. The feeling is thought to be reduced. In addition, the numerical value illustrated above is not a strict critical value in units of 1 mm but a substantial value in units of 0.5 cm.

  In order to realize a thin-walled frame structure wall that exhibits a shock absorbing function by crushing the unit buffer body 2, in the present embodiment, a substrate 4 and a preliminary assembly 5 including a plurality of straw pieces 51 are used. The formed flat block-shaped unit buffer 2 is used. As an example of the manufacturing method of the unit buffer 2, first, as shown in FIG. 3, a predetermined number (six in the example) of straws 3, 3,... Are arranged in parallel with their ends aligned. A wide adhesive tape 4 is wound around the entire outer periphery of the straws 3, 3,. The adhesive tape 4 is wound around the cutting line t in a state where the whole of the straws 3, 3,... Next, the integrated straws 3, 3,... Are cut at every cutting width (= H) corresponding to the thickness H with respect to the longitudinal direction of the straw (the axial direction of each straw), that is, the cutting line. Cut along h, h,... As a result, the overall size corresponds to the width corresponding to the outer diameter of the straw 3 (exactly the thickness obtained by adding the minute thickness of the adhesive tape T), the depth corresponding to the cutting width, and the outer diameter of the straw 3 described above. A straw as a cylindrical structure wall having a length corresponding to a value obtained by multiplying the predetermined number (each having an extremely thin wall thickness corresponding to the thickness of the straw 3) and the same number as the predetermined number A pre-assembly 5 is obtained in which the pieces 51, 51,... Are assembled and integrated in a state of being aligned in a row by a strip tape 52 that is a cut strip of the adhesive tape T. The straw 3 is a drinking straw formed by extrusion using a synthetic resin (for example, polypropylene or polyethylene), and has a diameter of about 3 mm to 15 mm and a length of about 210 mm. As the diameter increases, the later-described crushability of the unit buffer 2 increases with the same thickness H.

  Next, the formed preliminary assemblies 5, 5,... Are formed on the substrate 4 (see FIG. 1 or FIG. 2) so that the opening end surface of each straw piece 31 faces the front surface (upper surface in FIG. 1) to form a plane. Attached to the end of the substrate 4 so as to be adjacent and aligned in parallel (see FIG. 1). At this time, the adjacent preliminary aggregates 5 and 5 may be attached with an adhesive. In the case where the unit buffer body 2 is formed only by a predetermined number (for example, six) of the preliminary assemblies 5, 5,... Without the substrate 4, the entire band tapes 52, 52 are bonded together. The preliminary assemblies 5, 5,...

  1 and FIG. 2 illustrate an example in which a predetermined number of preliminary assemblies 5, 5,... Are attached on the substrate 4 to improve shape retention (performance of retaining the shape). The substrate 4 is added from the viewpoint of shape retention performance, and a resin sheet or paperboard may be used. From the viewpoint of disposal processing after use, paper is desirable. In the example of FIG. 1, a paper band is used as the substrate 4. As the paper band, for example, a paper band for handicrafts (12 to 13 or more strands of string that are joined together in a horizontal row and shaped like a belt) is cut into a predetermined length. What is necessary is just to use. By using the substrate 4, the shape retaining property of each unit buffer body 2 can be further improved, and at the same time, the substrate 4 is relatively moved in the direction of the impact indicated by the arrow in FIG. By arranging them on the opposite side), the received impact force can be uniformly distributed to each of the preliminary assemblies 5, 5,. Note that the substrate 4 is not necessarily essential for constituting the unit buffer 2.

  FIG. 4 shows a means for constructing a buffer structure using the unit buffer 2 for a region R of a certain garment T. This buffer structure forms a large number of receiving portions 7, 7,... Over the entire surface of the base fabric 6 in order to store and hold the unit buffer 2 with respect to the base fabric 6 having a shape corresponding to the region R. .. Are constituted by inserting the unit buffer bodies 2 into the accommodating portions 7, 7,... Belonging to the region in which the buffer function is to be exhibited from among the accommodating portions 7, 7. If the entire region R is desired to exhibit a buffering function, the unit buffer 2 is inserted and accommodated in all of the accommodating portions 7, 7,... Formed in the region R. In FIG. 4, an oval shape is shown as an example of the region R, but the shape of the region R can be freely set.

  Each said accommodating part 7 is formed as follows. As shown in FIG. 5, first, the base cloth 6 is placed in a state in which the accommodating portions 7 having a depth enough to allow the unit buffer 2 to fit into the base cloth 6 are arranged in a grid pattern. Bands 8a to 8n that are divided for each width k in the depth direction are prepared, and then the bands 8a to 8n are juxtaposed on the base cloth 6 with a slight gap (the base of FIG. 5). (See alternate long and short dash line on cloth 6). Then, the sewing machine is sewn so that the vertical sewing lines 9, 9,... Are inserted every horizontal interval (interval in the horizontal direction in FIG. 4) to which the unit buffer 2 can be inserted, and the horizontal direction Are sewn so that the horizontal stitching lines 10, 10,. The width k is not the vertical (X) dimension or the horizontal (Y) dimension of the unit buffer 2 but a dimension obtained by adding a margin for adding each horizontal sewing line 10 to the above dimensions. . As described above, for example, in the band cloth 8c (see FIGS. 4 and 6), the seven sewing portions 7, 7,... Are partitioned by the vertical sewing lines 9, 9,. Will be formed. In short, by placing the vertical sewing lines 9, 9,... And the horizontal sewing lines 10, 10,. .. Are formed so as to cover substantially all of the region R in a state of dividing the region R into a grid pattern. And the base fabric 6 in which many accommodating parts 7, 7, ... were formed with the band fabrics 8a-8n is applied to the site | part which wants to exhibit the buffer function of clothes T, and the outer periphery which goes around along the outer edge part of the base fabric 6 The sewing line 11 is inserted by sewing and is attached to the clothes T. Thereafter, the unit buffers 2 are individually placed in the accommodating portions 7, 7,. As described above, the unit buffer 2 and a plurality (at least two or more) of storage units 7 that can store the unit buffer 2 in a state where the predetermined region R to be provided with a buffer function is divided into a grid pattern. , 7,... Is completed.

  As a means for attaching the base fabric 6 to the garment T in this case, in addition to the above-described peripheral sewing line 11, as a fixing method, for example, a direct means by adhesion, etc. The indirect means used can be used. Moreover, in the case of a fixed system, said base fabric 6 can also be abbreviate | omitted. For example, the band fabrics 8a to 8n may be sewn directly to a predetermined portion of the target clothing T by the vertical sewing lines 9, 9,... And the horizontal sewing lines 10, 10,. In short, the fabric constituting the garment T is substituted for the base fabric 6.

  According to the buffer structure using the unit buffer 2 described above, the frame structure wall in which the unit buffer 2 surrounds or partitions a large number of minute spaces with a cylindrical thin wall (the cylindrical wall of each straw piece 51). Therefore, when an impact is received from the front (see the arrow direction in FIG. 2B), the cylinder wall of each straw piece 51 is buckled in the cylinder axis direction and crushed to absorb the impact force. be able to. In short, by adopting such a crushable structure, the impact force can be sufficiently absorbed and converged, and transmission of the impact force to the wearer or wearer's body can be cut off as much as possible. it can. In this respect, for example, compared with a buffer body using elasticity such as polyurethane foam, it is extremely effective as a body protecting function. When the impact is received from the front, the front substrate 4 transmits the impact to the rear straw pieces 51 in a dispersed state. In addition, since there are a number of voids between the framework structural walls, extremely high air permeability is ensured, and even if applied to clothes, etc., there will be no adverse effects such as stuffiness in summer, and in order to keep warm in winter It becomes the air layer of this, and heat insulation can also be acquired now.

  Moreover, the unit buffer body 2 is formed in a relatively small size, and is individually accommodated and accommodated in a large number of accommodating portions 7, 7,... Arranged in a grid pattern so as to cover the region R to be protected by the buffer function. Therefore, even if the region R is a curved region corresponding to the body shape, it can be surely covered with the unit buffer 2 along the curved surface, Even if the region R is bent by physical movement, the unit buffer 2 can follow the bending. Since the unit buffer body 2 is formed mainly of an extremely thin straw piece 51, it is lighter than those using the polyurethane foam pad or plate as a buffer body, and is suitable for the wearer or wearer. It is possible to avoid a burden due to its weight.

  Further, the unit buffer 2 can be easily taken in and out of each accommodating portion 7, and the replacement work of taking out the unit buffer 2 that has been crushed or damaged and inserting a new unit buffer 2 can be easily performed. it can.

Second Embodiment
FIG. 7 or FIG. 8 is configured as a trouser (outer pants) shape as a hip protector to which the buffer structure according to the present invention is applied. Hereinafter, this trouser-shaped hip protector is called trousers 20 and 21 with a buffer function. As the trouser bodies 20a and 21a constituting the trousers 20 and 21 with the buffer function, sleeping trousers may be used in addition to the outer trousers. In addition, an elastic material may be used as the outer fabric 22 (see FIG. 7) that constitutes the outer portion of the pants with the intention of being worn by the elderly, so that it can be moved more easily. And with respect to the trouser main bodies 20a and 21a which comprise the trousers 20 and 21 with a buffer function, in area | region R1, R1 corresponded to the both outer area | regions (both outer area | regions of the greater trochanter part of a femur) of a pants wearer's waist | hip | lumbar part. A buffer structure is applied.

  Specifically, in the structure shown in FIG. 7, buffer structures 23 and 23 are formed separately from the trouser body 20a, and are attached to the trouser body 20a. That is, for example, the case where the buffer structure of the first embodiment is applied as the buffer structure 23 will be described as an example. The band fabrics 8a to 8n are connected to the vertical stitch line 9 with respect to the base fabric 6 (see FIGS. 4 and 5). , 9,... And the side stitching lines 10, 10... Are sewn, and the unit buffer body 2 is inserted and accommodated and held in each accommodating portion 7 arranged in a grid pattern, and the outer surface is held in this state. The buffer structure 23 is formed by covering with a covering cloth 231. Thereafter, each buffer structure 23 is arranged so as to cover a predetermined region of the trouser body 20a, and is fixedly attached by sewing or adhesion, or detachably attached by a hook-and-loop fastener.

  In the trouser main body 21 a shown in FIG. 8, pockets 24 and 24 are formed so as to cover the same regions R <b> 1 and R <b> 1 as in FIG. 7, and a buffer structure 25 is attached inside each pocket 24. The buffer structure 25 may be attached to the trouser body 21a in a fixed manner by means such as sewing or adhesion directly to the outer fabric of the trouser body 21a. Further, an inner pocket 26 is formed, and the buffer structure 25 is detachably accommodated in the inner pocket 26. Taking the case where the buffer structure of the first embodiment is applied as the buffer structure 25 as an example, as shown in FIG. 9A, the overall shape and size of the base fabric 6a is set in the inner space of the inner pocket 26. .. Are set so that they match, and band fabrics 81, 81,... Are applied to the base fabric 6 a having such a shape, and the vertical sewing lines 9, 9,. The sections 7, 7,... Are partitioned and the unit buffers 2 are accommodated in the respective accommodating portions 7. In the illustrated example, five storage portions 7, 7,... Are formed horizontally in six rows, and 30 unit buffer bodies 2 are stored in total.

  Further, when an oval unit buffer body 12 is applied as the buffer structure 25, as shown in FIG. 9B, a base cloth 14a having a shape and size set in the same manner as the base cloth 6a described above. Are sewn together with the vertical sewing lines 16, 16,... And the horizontal sewing lines 17, 17,..., So that the vertically long accommodating portions 13, 13,. A buffer structure 25 is formed by accommodating the unit buffer 12 in each storage portion 13. In this example, five storage portions 13, 13,... Are horizontally formed in two rows, and a total of ten unit buffer bodies 12 are stored and held.

  In the case of the trousers 20 and 21 with the buffer function described above, the unit buffer body 2 and the like constituting the buffer structures 23 and 25 are formed mainly of the extremely thin-walled straw piece 51, and thus the conventional synthesis. The weight can be reduced as compared with the case where a cushioning material using a resin pad or plate is used, and since a large number of voids exist due to the use of a frame structure wall, air permeability in summer and winter heat retention can be ensured. For this reason, wearing promotion of the trousers 20 and 21 with a buffer function which applied the buffer structure 23,23 or 25,25 with respect to elderly people can be aimed at. In addition, since the shock absorbing mechanism adopts a crushable structure using a thin-walled frame structure wall, when the wearer of the trousers 20 and 21 with a shock absorbing function falls, the shock force accompanying the falling is surely absorbed. Transmission of impact force to the lumbar region (large trochanter of the femur) can be suppressed / blocked, and fall fracture can be effectively and reliably prevented. In addition, when the shock absorbing function is exerted on the buffer structures 23 and 25, the buffer structures 23 and 25 are avoided from becoming thick, so that the buffer structures 23 and 25 are relatively thin and not bulky. Therefore, while eliminating as much as possible inconveniences that hinder the promotion of wearing by elderly people, it is also possible to exert an impact absorbing function for preventing falling fractures.

<Third Embodiment>
FIG. 10 is mainly composed of a stall 30 with a buffer function as a hip protector to which the buffer structure according to the present invention is applied. The stall 30 is combined with trousers 31 provided with means for temporary holding thereof. Indicates. The trousers 31 include sleeping trousers in addition to outer trousers. In particular, the stall 30 with a buffer function is intended to be combined with outer trousers during the day and with night trousers at night. In addition, it is essential that the stall 30 has at least a length such that both side ends cover the outside of the waist while being hung on the neck. In this regard, not only the stall 30 but, for example, a muffler that is long enough to cover both sides of the waist if both side ends are hung down with the central portion in the length direction hung on the neck. Of course, the following buffer function may be provided. In short, even if it is named “stole”, “muffler”, “shawl”, etc., if it has the configuration of this embodiment, the name of the hip protector according to this embodiment is different just by having a different name. is there.

  Specifically, the stall 30 of the present embodiment has a length and a width such that both side end portions 301 and 301 cover the outer side of the waist of the wearer P in a state of being hung or wound around the neck of the wearer P. Yes, the buffer structures 32, 32 formed by applying either the buffer structure of the first embodiment or the buffer structure described in the second embodiment are attached to both end portions 301, 301. Is. And each edge part 301 provided with the buffer structures 32 and 32 can be temporarily fixed to the waist outer side area | region of the trousers 31 so that attachment or detachment is possible. As a means for temporary fixing, a hook-and-loop fastener 33 or a snap button stop may be employed. For example, when the surface fastener 33 is used, as shown in FIG. 10, one side 33a of the male side and the female side of the surface fastener 33 is attached to the back side of each end portion 301 provided with the buffer structures 32, 32, The other side 33b of the male / female side of the hook-and-loop fastener 33 is attached to the waist outer region of the trouser 31 so that each end 301 provided with the buffer structures 32 and 32 can be attached to and detached from the predetermined region of the trouser 31. What is necessary is just to enable it to fix temporarily.

  In order to provide the buffer structure 32 at each end 301 of the stall 30, as described above, it is possible to use a means such as sewing or adhesion in order to provide it in a fixed manner. For this purpose, a means such as storage in a pocket or a hook-and-loop fastener may be used. FIG. 10 shows an example in which storage in a pocket is adopted and further fashion and functionality are added. That is, an outer pocket 34 is formed on the front side surface of each end portion 301 of the stall 30 using a material forming the stall 30 or other materials, and one or more inner pockets 35, 35 (two cases are shown in FIG. 10). And the buffer structure 32 is inserted in each inner pocket 35, and is accommodated so that attachment or detachment is possible. Note that reference numeral 341 in the figure denotes a flap of the outer pocket 34.

  For the buffer structure 32, for example, the buffer structure 25 described in FIG. 9A or 9B may be used.

  In the case of this third embodiment, when using externally worn trousers as the trousers 31, the respective end portions 301 of the stall 30 that are hung or wrapped around the neck are temporarily fixed to the trousers 31 by the surface fasteners 33. To do. Thereby, the waist outer region of the wearer P will be covered with the buffer structures 32, 32, so that the shock received on the outer side of the waist in the event of a fall should be buffered and the impact force transmitted directly to the waist. Can be avoided. Thereby, it is possible to prevent the occurrence of falling fractures particularly in the femoral neck. In addition, in the case of the present embodiment, since the buffer structures 32 and 32 are applied to the stall 30, the fashionability is high, so that the wear of the stall 30 can be promoted and the prevention of falling fractures of the elderly is promoted. It can contribute to. On the other hand, when sleeping trousers are used as the trousers 31, the stall 30 with a buffer function is hung on the neck before going up to the toilet for sleeping on a bed at night. , 301 is effective as a measure for preventing falling fractures in addition to keeping warm as a measure for cooling.

<Fourth embodiment>
FIG. 11 shows an embodiment configured as a waist pouch with a buffer function as a hip protector to which the buffer structure according to the present invention is applied. That is, the hip protector is constituted by the waist pouch 40 with a buffer function. In this embodiment, the name “waist pouch” is used, but as long as it has the same configuration and function, another name such as “belt” is also a hip protector according to the present invention.

  The waist pouch 40 is a belt body 41 that can be wound around the waist of the wearer P, pouch portions 42 and 42 provided at at least two specific positions of the belt body 41, and the pouch portions 42 and 42. And a buffer structure 43 provided individually in each of the above.

  The belt body 41 is preferably formed from candy rubber, and one end 44a and the other end 44b of the hook-and-loop fastener 44 are provided at both side ends 411 and 412 as means for temporary holding. And as shown in FIG.11 (b), in the state hold | maintained at the wearer P by making it wind around the waist | hip | lumbar part of the wearer P, and overlapping both ends 411 and 412 and making it couple | bond with the surface fastener 44, Two pouch portions 42 are formed on the belt body 41 so as to cover both outer regions of the waist of the wearer P. Specifically, the belt body 41 itself is also wide enough to cover both outer sides of the waist of the wearer P, and a pocket forming material 421 for forming a pouch portion 42 there, and a flap forming material The pouch portions 42 are formed by sewing the 422. Further, an inner pocket 45 is formed inside each pouch portion 42, and a buffer structure 43 is inserted into the inner pocket 45 so as to be detachable. The position and size of the inner pocket 45 and the buffer structure 43 accommodated therein are set so as to cover the waist outer region of the wearer P (particularly the region covering the greater trochanter of the femur).

  The buffer structure 43 is configured by applying any one or more buffer structures of the first to third embodiments, similar to those described in the previous embodiments. The buffer structure 25 described with reference to 9 (a) or FIG. 9 (b) may be used.

  In the case of the waist pouch 40 with a buffer function of this embodiment, there is no sense of incongruity with wearing on the waist when the wearer P goes out. Rather, if worn, small items are put in the pouch portions 42 and 42. Since the use value becomes higher, it is possible to promote wearing and wearing. And if it mounts | wears, since the fall fracture will be aimed at by the buffer structure 43, promotion of fall fracture prevention by promotion of mounting | wearing / wearing can be aimed at.
