Description

  The present invention relates to a head support aid that suppresses the neck from bending backward when looking up.

  Workers working in high-rise construction sites, huge production lines, and the like often look up upwards or maintain a posture of looking up upwards for a long time, which often places an excessive burden on the neck. The excessively burdened neck not only causes fatigue to the operator, but also causes stiffness of the neck and shoulders, possibly causing health problems. The problem caused by such a burden on the neck is caused by trying to support the head that has been bent backward with the bent neck when looking up. Then, the head support auxiliary tool which supports the head which falls backward with a neck is proposed (patent documents 1 and patent documents 2).

  The head support auxiliary tool disclosed in Patent Document 1 includes a continuous portion on the occipital side, an extended portion extending from the continuous portion, and a protrusion that strikes between the shoulders of the operator continuously to the extended portion. It is a working helmet provided with this part (patent documents 1, [0010]). In the work helmet disclosed in Patent Document 1, when the worker looks up, the abutting portion that continues from the connecting portion on the back of the head abuts between the shoulders of the worker, and the worker's helmet is interposed through the work helmet. By supporting the head, the weight of the head and work helmet when looking up is supported not only on the neck but also on the shoulder, thereby reducing the burden on the neck (Patent Document 1 [0011] [ 0012]).

  The head support auxiliary tool disclosed in Patent Document 2 is a point-of-view-up support device that is supported from the shoulder to the back by an object that supports the back of the head (Patent Document 2, [Claim 1] [0002]). The point-of-view-up support device disclosed in Patent Document 2 is provided with a shoulder belt, a backrest having a support on the upper surface, and a head tilted backward by the support. By making the support part an air mat or supporting the support part via a leaf spring against the backrest, it gives elasticity to the support part, so that it can be used by children and adults with different head pressures that tilt backwards. I can do it.

  The head support auxiliary tool (working helmet) disclosed in Patent Document 1 is such that the portion that supports the head until the abutment portion, which is the tip of the extension portion, abuts between the shoulders until the head is supported is the neck. It is only, and the burden on the neck that bends backward cannot be reduced. In addition, since the stability of the support of the operator's head depends on how the work helmet is attached, even if the abutment portion is in a state of striking between the shoulders, If it slips, the burden of the neck which will bend backward will occur.

  Similarly to the head support assisting tool disclosed in Patent Document 1, the head support assisting tool disclosed in Patent Document 2 (the upward-pointing head support device) has a portion that supports the head until the head hits the support head. It is only the neck, and the burden on the neck that bends backward cannot be reduced. In addition, the neck is supported by the back rest carried on the back, and the back rest is supported on the shoulder via the shoulder belt, so if the shoulder belt is loose, the back rest moves, and as a result, the neck support is displaced, After all, the burden of the neck that bends backward occurs.

  In this way, conventional head support aids support the head with the neck only after the head tilts beyond a certain angle, and the work helmet and backrest are displaced and support the head stably. There was a problem that it was impossible to reduce the burden on the neck. In addition, since the neck is allowed to bend in the first place, even if the head is supported by another member, the burden due to the neck being bent backward is not reduced. Therefore, we studied to develop a head support aid that can restrain the neck from bending backwards and reduce the burden on the neck regardless of the tilt angle of the head.

  What has been developed as a result of the study is composed of a neck support surface and a pair of left and right hanging surfaces extending from the neck support surface, and the neck support surface follows the back of the neck when addressed to the back of the neck of the operator. It is an elastic resin plate that is elastically deformed mainly left and right, and the hanging surface is elastically deformed mainly up and down following the neck circumference when it is directed around the neck from the neck support surface addressed to the back of the neck to the front of the neck. With the elastic resin plate, the end part that is abutted or overlapped below the front of the neck is made detachable, and the hanging surface addressed around the neck is operated with the neck support surface directed to the back of the neck. It is a head support auxiliary tool that suppresses the neck from bending backward by a neck support surface fixed in a state of being addressed to the back surface of the neck by being sandwiched between an operator and work clothes worn by the operator .

  The head support auxiliary tool of the present invention does not assist the support of the head tilted backward, but suppresses the neck from bending backward at the neck support surface directed to the back of the neck, and tilts backward. A neck that does not bend directly under the head is positioned to support the head, thereby reducing the burden on the neck. The circumference of the neck is around the base of the neck connecting the lower back of the neck, the lower side of the neck and the lower front of the neck, the lower back of the neck is continuous with the back, the lower neck side is the shoulder, and the lower front of the neck is continuous with the chest. The hanging surface is sandwiched between the worker and work clothes over the neck by connecting the ends. The neck support surface is fixed in position via a hanging surface sandwiched between the worker and work clothes, and stably maintains a state of being directed to the back of the neck.

  The neck support surface is mainly elastically deformed to the left and right and is in close contact with the back of the neck, and the elastic deformation of the front and rear is suppressed, thereby suppressing the neck from bending backward. Here, as described above, the neck support surface made of the elastic resin plate is slightly bent in the front and rear directions and allows the neck to bend slightly backward, although the elastic deformation in the front and rear directions is suppressed. Further, since the neck support surface is elastically deformed left and right, the neck is allowed to tilt in an oblique direction including the left and right. In this way, the neck support surface only prevents the neck from bending backward and does not unduly limit the degree of freedom of the neck.

  The hanging surface is mainly elastically deformed up and down and follows the neck, and is sandwiched between the worker wearing the head support auxiliary tool and the work clothes worn by the worker and fixed in position. . When an operator wears work clothes directly on the skin, the hanging surface is sandwiched between the skin and the work clothes, and movement is suppressed or prevented by friction with the work clothes. Since the worker usually wears the inner shirt, the hanging surface is sandwiched between the inner shirt and the work clothes, and the movement is better suppressed or prevented by friction between the inner shirt and the work clothes. From this, the surface of the hanging surface is preferably a rough surface where the frictional force is increased.

  The neck support surface and the hanging surface are integral elastic resin plates, and it is preferable that the left and right ends of the neck supporting surface directed to the back of the neck are twisted and the hanging surface is directed to the circumference of the neck. The neck support surface and the hanging surface may be configured such that both are connected as separate bodies. However, if both are formed of an integral resin plate, the left and right ends of the neck support surface are twisted and the hanging surface is directed to the neck circumference. It will be garbled. As a result, the rigidity of the twisted left and right ends of the neck support surface curved left and right is enhanced, the neck support surface easily opposes the neck that is about to bend backward, and the neck tries to bend backward. This can be better controlled.

  If the neck support surface is provided with a large number of openings, it will bend easily to the left and right along the back of the neck, and will be slightly easier to bend back and forth along the back of the neck. Can be better suppressed from bending backward. The opening is basically a circular or long hole of 1 cm or less, and a structure provided symmetrically on the neck support surface, but the size, shape and arrangement are not limited, and the larger the opening or the denser the opening, the more elastic it is. Bending due to deformation is promoted. In addition, the opening serves as a vent for the back of the neck that is easily stuffy due to the neck support surface that is in close contact with it, and also serves to prevent the stuffiness.

  The neck support surface can be detachably attached with a cooling agent or a heat insulating agent to cool the blood vessels flowing on the back of the neck to lower the heat of the whole body (cooling agent), and conversely to cool and warm the blood vessels to raise the whole body heat. You can. Since the neck support surface is brought into close contact with the back surface of the neck, it is easy to maintain a state in which the cold or warming agent attached to the neck support surface is close to the blood vessel flowing on the back surface of the neck. In addition, since the neck support surface is elastically deformed, it is easy to maintain a state in which the cold-retaining agent or the heat-retaining agent is brought close to the back of the neck following the allowable front and left-right movements of the neck. Thus, the neck support surface which comprises a head support auxiliary tool is suitable as a holding | maintenance member of the cold insulation agent or heat insulation agent addressed to a neck back surface.

  Various conventionally known means can be used as the means for attaching / detaching the cryogen or the heat insulating agent to the neck support surface. For example, a cooling agent or a heat insulating agent is inserted and held in a slit or pocket provided on the neck support surface and directed to the back of the neck via an elastic resin plate on the neck support surface, or covered with a stretchable fabric on the neck support surface. A cold-retaining agent or a heat-retaining agent is inserted and held between the bag and the neck support surface, and is directed to the back of the neck via the stretchable fabric of the bag or the elastic resin plate of the neck support surface. Moreover, you may provide a double-sided tape in a cold insulating agent or a heat insulating agent, and may provide the male surface and female surface of a pair of hook-and-loop fastener in a neck support surface and a cold insulating agent or a heat insulating agent. As described above, it is important that the cold insulating agent or the thermal insulating agent does not directly touch the back of the neck.

  The hanging surface may be provided with a buffer surface that is an elastic resin plate that projects from the circumference of the operator's neck toward the shoulder. When the operator wearing the head support aid of the present invention carries a heavy load on the shoulder, the cushioning surface is interposed between the heavy load and the shoulder together with the work clothes, and is elastic according to the shoulder and the heavy load. By deforming and increasing the contact area with both the shoulder and the heavy object, the pressure applied to the shoulder is reduced and the burden on the shoulder is reduced. The buffer surface may be an elastic resin plate integral with the hanging surface, or may be a separate elastic resin plate from the hanging surface, but by specifying the positional relationship between the hanging surface and When the hung surface is hung around the neck, the position of protruding toward the shoulder is specified.

  For example, a combination of a button and a button hole, a combination of a hook and a hook receiver, a snap button, and a hook-and-loop fastener are conceivable as the configuration for making the end of the hanging surface detachable. Preferably, the hooking surface is provided with a hooking projection at one end and a hooking hole at the other end, and the end is detachable by inserting or removing the hooking projection into the hooking hole. The hooking protrusion and the hooking hole are obtained by integrally molding a part of the elastic resin plate constituting the hooking surface. The hooking protrusion only needs to have a configuration in which a hook portion that hooks to the inner peripheral edge of the hooking hole is provided. Engage with the periphery.

  The head support auxiliary tool of the present invention does not reduce the burden on the neck by supporting the head tilted backward with the bent neck, so that the neck does not bend in the first place and tilts backward. The head is supported by the neck to reduce the burden on the neck. Since the head is located just above the neck, the weight of the head is added to the body supporting the neck, not the neck, which also contributes to reducing the burden on the neck. In addition, since the neck support surface and the hanging surface that come into contact with the neck and shoulder are both made of an elastic resin plate, there is an advantage that the neck and shoulder are not damaged.

  When the neck support surface and the hanging surface are formed as an integral elastic resin plate, a manufacturing advantage can be obtained in which the neck supporting surface and the hanging surface can be configured by a single molding operation (for example, manufacturing by die cutting from an original plate). Further, the connecting portion of the neck support surface and the hanging surface can also be formed of an elastic resin plate, and it is not necessary to provide a seam, so that the neck supporting surface and the hanging surface can be elastically deformed, Even when the hung surface is twisted, it is possible to avoid concentration of stress and to obtain an advantage of avoiding deterioration and breakage of each part.

  A large number of openings provided in the neck support surface have a function of adjusting the ease of elastic deformation of the neck support surface so that the neck support surface can easily adhere to the back surface of the neck. As a result, even if the elastic resin plate on the neck support surface is thick and difficult to follow the neck back surface as it is, it is possible to adhere to the back surface of the neck by devising the size and arrangement of each of the many openings. This has the effect of allowing the use of a neck support surface with a thickness that resists bending the neck backwards. In addition, a large number of openings function as air holes as they are, and bring about various effects such as a function of preventing stuffiness caused by bringing the neck support surface into close contact with the back of the neck.

  When the head support aid of the present invention is used outdoors in the summer or winter, the cryostat or heat insulator attached to and detached from the neck support surface can cool or warm the back of the neck to reduce the heat of the operator's whole body. , Give the work to raise. Further, the buffer surface provided on the hanging surface gives a function of reducing the burden on the shoulder when the head support auxiliary tool of the present invention is used at a site where a heavy object is carried on the shoulder. These mean that there is an effect brought about in addition to the effect of reducing the burden on the neck, and the usage scenes of the head support aid of the present invention are increased.

  There are various conceivable configurations for making the end of the hanging surface detachable, but when the hooking protrusion and the hooking hole are combined, the hooking protrusion and the hooking hole are simultaneously formed when the hooking surface that is an elastic resin plate is formed. It is possible to obtain the effect of improving productivity. In addition, the hooking protrusion is engaged with the inner peripheral edge of the hooking hole to maintain the connection between the end portions of the hooking surface. Therefore, it can be said that it is an attachment / detachment means suitable for the head support auxiliary tool of the present invention.

FIG. 8 is a front view corresponding to FIG. 7 showing a state where an operator wearing the head support auxiliary tool of this example and further wearing work clothes looks up.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the head support auxiliary tool 1 of this example includes a neck support surface 11, a pair of left and right hanging surfaces 12, 12, and buffer surfaces 121, 121 protruding from each hanging surface 12. Are made of a single elastic resin plate of foamed resin (foamed polyethylene). The head support auxiliary tool 1 can be attached by being wrapped around the neck 22 of the operator 2 (see the succeeding FIG. 4 and subsequent figures) and provided with elasticity that restores to its original shape when removed from the neck 22. As described above, an elastic resin plate having a thickness of 5 mm made of foamed resin (foamed polyethylene) may be used. The head support auxiliary tool 1 of this example has a reversible specification that can be used even if the left and right sides are reversed, with a bilaterally symmetric shape and no distinction between the front and back sides.

  The neck support surface 11 has a substantially hexagonal shape in a front view having parallel upper and lower sides, and the wrapping surface 12 extends from the oblique lower sides of the left and right ends via a constriction (a narrow portion) 124. The shape and size of the neck support surface 11 can be freely viewed, but the neck support surface 11 is required to suppress the neck 22 to which the neck support surface 11 is bent backward. The position and size addressed to the neck back surface 221 so as to have a hexagonal shape may be a shape and size in front view that satisfies the above function. The neck support surface 11 of the present example is directed to the left and right center of the neck back surface 221 vertically, in order to reduce the size addressed toward the neck side surface 223 so as not to hinder the left and right movement of the neck 22. The front view has a substantially hexagonal shape with parallel upper and lower sides.

  In addition, the neck support surface 11 of this example exhibits a function of suppressing bending of the neck 22 backward as described above as an elastic resin plate having a thickness of 5 mm made of foam resin (foamed polyethylene) having elasticity. However, by providing a large number of openings 111 made of long holes facing in two vertical and horizontal directions and circular holes whose diameter is the length of the long holes, the neck back surface 221 bends in the left-right direction following the neck back surface 221. It is designed to be in close contact with 221. The bending in the left-right direction of the neck support surface 11 suppresses the neck support surface 11 from bending in the front-rear direction, and makes it easy to exert the function of the neck support surface 11 suppressing the neck 22 from bending backward. The large number of openings 111 function as vents to prevent stuffiness due to the neck support surface 11 in close contact.

  The hanging surface 12 is a bent plate-like portion having a downwardly convex bend, facing the left and right directions from the vicinity of the constriction 124 that is a connecting portion with the neck support surface 11, and has a substantially fan-shaped buffer surface 121 in front view. Is overhanging. The hanging surface 12 is sandwiched between the inner shirt 25 and the work clothes 24 of the worker 2 to ensure the mounting stability of the head support auxiliary tool 1 to the worker 2 and to hang around the neck. At this time, the neck 22 is restrained from being bent backward by the neck support surface 11 bent in the left-right direction by being largely twisted with respect to the neck support surface 11 with the constriction 124 interposed therebetween.

  The hooking surface 12 protruding to the left has a hooking protrusion 122 at the end, and the hooking surface protruding to the right has a hooking hole 123 at the end. The left and right hanging surfaces 12, 12 are hung around the neck with the neck support surface 11 directed to the neck back surface 211, and the hook projection 122 inserted into the hook hole 123 on the neck front surface 222 is formed in the hook hole. By engaging with 123, the ends are connected (refer to the succeeding figure 4 and subsequent figures). Conversely, the left and right hanging surfaces 12, 12 are released from connection when the hooking protrusion 122 inserted in the hooking hole 123 is pulled out of the hooking hole 123.

  The hooking protrusion 122 is a trapezoidal shape that is line-symmetric with respect to the extending direction axis of the hooking surface 12 protruding leftward, and is a hook portion that engages the left and right corners with the inner peripheral edge of the hooking hole 123. The engagement hole 123 has a triangular shape in front view that is convex in the extending direction of the hanging surface 12 that protrudes to the right. The hooking protrusion 122 is not limited to the illustrated shape as long as it has a configuration in which a hook portion hooked to the inner peripheral edge of the hooking hole is provided. The hooking protrusion 122 can be elastically deformed as a part of the hanging surface 12 that is an elastic resin plate, and is restored after passing through the hooking hole 123 in a rounded state, so that the flange portion of the hooking hole 123 is restored. Engage with the inner periphery.

  As apparent from FIGS. 1 and 2, the engaging protrusion 122 of this example is configured as a residue obtained by cutting off the end material from the end portion having the same arcuate outer peripheral edge as the hanging surface 12 projecting rightward. . Thereby, the head support auxiliary tool 1 of this example is an elastic resin plate provided with an end portion having an arcuate outer peripheral edge, without the hooking protrusion 122 and the hooking hole 123, from the raw material elastic resin plate. Can be manufactured by forming a hooking protrusion 122 at one end and a hooking hole 123 at the other end. This is an advantage of increasing the productivity of the head support auxiliary tool 1 of the present invention.

  When the hanging surface 12 is hung around the neck, the buffer surface 121 overhangs on the shoulder 23 of the operator 2 (see the successor figure 6), and between the heavy object carried by the operator 2 and the shoulder 23. Intervene to reduce the burden on the shoulder 23 due to heavy objects. The buffer surface 121 of this example protrudes from the hanging surface 12 in the vicinity of the constriction 124 at the boundary between the neck supporting surface 11 and the hanging surface 12, and when the hanging surface 12 is hung around the neck, It is formed so as to rest on two shoulders 23. Further, the buffer surface 121 is sandwiched between the inner shirt 25 and the work clothes 24 of the worker 2 as well as the hanging surface 12 to ensure the mounting stability of the head support auxiliary tool 1 to the worker 2. There is also.

  In addition, as shown in FIG. 3, the head support auxiliary tool 1 of this example covers a neck bag 11 with a tubular bag 112 made of a stretchable mesh fabric, and the bag 112 and the neck support surface 11. By holding the cold-reserving agent 113 between the two, the blood flowing through the neck back surface 221 can be cooled and the whole body heat can be lowered. Since the bag 112 wraps the neck support surface 11, the cold insulating agent 113 can be held on the front side or the back side of the neck support surface 11. When the cold insulation agent 113 is held on the front side of the neck support surface 11, the cold insulation agent 113 is preferably wrapped around a cloth or the like so as not to touch the neck 22 directly. When the cold insulation agent 113 is held on the back side of the neck support surface 11, the cold insulation agent 113 indirectly touches the neck 22 through the neck support surface 11, and therefore may be stored in the bag 112 as it is.

  The head support auxiliary tool 1 of this example is mounted and used as follows (in FIG. 4 and subsequent figures, the illustration of the opening 111, the bag 112, and the cooling agent 113 is omitted for the sake of illustration). Before wearing the work clothes 24 which is the outerwear, the worker 2 puts the left and right hanging surfaces 12 and 12 from the neck side surface 223 to the neck front surface 221 in a state where the neck support surface 11 is directed to the neck back surface 221. As shown in FIGS. 4 to 6, the hooking protrusion 122 (left side in FIG. 4) provided on the left hooking surface 12 is inserted into the hooking hole 123 provided on the right hooking surface 12. The wrapping surfaces 12 and 12 are connected in the vicinity of the neck front surface 222 or the chest just below. Since the head support auxiliary tool 1 of this example has a reversible specification that does not distinguish between left and right, the hanging surface 12 having the hooking protrusion 122 may be on the right, and the hanging surface 12 having the hooking hole 123 may be on the left.

  In the state where the end portions of the hanging surfaces 12 and 12 hung around the neck are connected, the head support auxiliary tool 1 is not pressed, so that the neck supporting surface 11 is not necessarily attached to the neck back surface 221 due to its own elasticity. They are not in close contact with each other, and the hanging surfaces 12 and 12 float away from the chest and the cushioning surface 121 from the shoulder 23 (FIGS. 4 to 6 show that the neck support surface 11 is the back of the neck for convenience of explanation) In FIG. 221, the hanging surfaces 12 and 12 are deformed along the chest, and the cushioning surface 121 is deformed along the shoulder 23 so as to be in close contact). For this reason, when the work clothes 24 are not worn, the neck support surface 11 of the head support auxiliary tool 1 cannot suppress the bending of the neck 22 to the rear.

  Thus, when the operator 2 wears the work clothes 24 with the head support auxiliary tool 1 attached to the circumference of the neck, as shown in FIGS. The hanging surface 12 and the buffer surface 121 other than the surface 11 are sandwiched between the inner shirt 25 and the work clothes 24 of the worker 2, and the mounting stability of the head support auxiliary tool 1 to the worker 2 is ensured. Further, the head support aid 1 is less likely to be displaced due to friction with the inner shirt and the work clothes 24. Then, the hanging surface 12 twists the constriction 124 that is a boundary with the neck support surface 11 to closely contact the body of the operator 2 or the inner shirt 25, so that the neck support surface 11 is in close contact with the neck back surface 221. Bend. Thereby, the neck support surface 11 suppresses the neck 22 from bending backward.

  In this way, when the operator 2 wearing the head support auxiliary tool 1 under the work clothes 24 looks up, as shown in FIG. 10, the neck support surface 11 prevents the neck 22 from bending backward. Therefore, only the head 21 of the worker 2 is tilted rearward, and the head 21 is positioned immediately above the neck 22. Thereby, the burden by supporting the head 21 with the neck 22 is reduced or eased. When the operator 2 stops looking up and returns the head to the original position, the neck support surface 11 that has been elastically deformed by being pushed by the neck 22 is restored and returned to a state in which it is in close contact with the straight neck back surface 221 (FIG. 9). reference).

  The neck support surface 11 opposes the neck 22 that is to bend backwards, as long as the surface 12 and the buffer surface 121 are sandwiched between the inner shirt 25 and the work clothes 24 and the position is fixed. For this reason, for example, if the neck 22 is bent largely backward to avoid dangerous materials, the entire head support auxiliary tool 1 is displaced, and the bending of the neck 22 is allowed. As described above, the head support assisting tool 1 of the present invention allows the neck 22 to bend without overcoming the bending of the neck 22 while suppressing the bending of the neck 22 when looking upward in the normal operation. No worry about hurting neck 22.

  In addition, as described above, the head support auxiliary tool 1 of the present example holds the cryogen 113 or a heat insulator (not shown) on the neck support surface 11 to cool or warm the blood vessels flowing on the neck back surface 221. Thus, the heat of the worker 2 can be lowered or raised. The head support assisting tool 1 is assumed to be used by the worker 2 during outdoor work, and such cooling or heating by holding the cold insulating agent 113 or the heat insulating agent is a burden on the worker 2 due to the outside temperature of the work environment. Reduce. Thus, the head support aid 1 of the present invention not only reduces the physical burden by suppressing the bending of the neck 22, but also adds the function of adjusting the body temperature to reduce the physiological burden.
