Description

[Technical field]

[0001] The present disclosure relates to a head support device that is attached to and detached from a shampoo bowl to support the head of a person to be treated. [Background technology]

[0002] Conventionally, hair salons and other beauty salons have devices used for treatments such as shampooing and scalp massage, such as a portable shampoo bowl described in Patent Document 1. A head support device for supporting the head of a person receiving treatment is attached to this shampoo bowl.

[0003] In the head support device, a member for supporting the back of the head of the person to be treated (the head support base in Patent Document 1) is suspended via a rotating shaft between a pair of left and right columnar members, and a member for supporting the neck of the person to be treated (the neck rest in Patent Document 1) is suspended via a rotating shaft between the head support bases. When the head of the person to be treated is placed on the head support device, both members swing via the two rotating shafts depending on the posture of the head. Therefore, the head support device flexibly adapts to the posture of the person to be treated. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2017-77378 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the above-mentioned head support device, the parts from which the various components (the head support base and the neck rest) are suspended are exposed around the head of the patient, which interferes with the therapist's touching of the back of the head or the nape of the neck, hindering the treatment. In addition, cleaning the rotating shaft is also troublesome.

[0006] The present disclosure has been proposed in consideration of the above-mentioned circumstances, and aims to provide a head support device that has a structure that does not interfere with treatment and is easy to clean. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the head support device disclosed herein is a head support device that is attached and detached to the edge of a shampoo bowl to support the head of a person to be treated, and has a base portion that is attached to the edge of the shampoo bowl, and a oscillating portion that is connected onto the base portion by a connecting structure, and the oscillating portion has a first abutment portion that abuts the back of the head or the vicinity of the back of the head, a protruding support portion that rises upward on the side opposite the inside of the shampoo bowl from the first abutment portion, and a second abutment portion that is attached from the upper end side of the protruding support portion to contain the protruding support portion on the inside and the outside of the head abuts against the neck or the vicinity of the neck, and is characterized in that the oscillating portion oscillates toward the inside or outside of the shampoo bowl relative to the base portion, and the second abutment portion oscillates toward the inside or outside of the shampoo bowl, with the upper end of the protruding support portion as a fulcrum.

[0008] The head support device according to the present disclosure is characterized in that the second contact portion is placed on an upper end portion of the protruding support portion and is detachable.

[0009] The head support device of the present disclosure is characterized in that the protruding support portions are configured in a pair on the left and right sides intersecting the direction in which the second abutment portion oscillates, and the second abutment portions are recessed between the protruding support portions.

[0010] The head support device of the present disclosure is characterized in that the connecting structure is composed of a rail portion extending in the direction in which the oscillating portion oscillates and configured as a pair on the left and right, and a shaft portion configured as a pair on the left and right and connected to each of the rail portions.

[0011] The head support device according to the present disclosure is characterized in that the shaft portions protrude laterally to the left and right from the inside of the rail portions through the rail portions toward the outside.

[0012] The head support device of the present disclosure is characterized in that the second abutment portion has a cover portion that covers a concave neck rest space formed on the edge of the shampoo bowl for the recipient's neck to pass through.

[0013] The hairdressing and beauty device disclosed herein is characterized by having a treatment table used by the person to be treated, a shampoo bowl arranged behind the backrest of the treatment table, and a head support device described in claim 1 or claim 2 attached to the shampoo bowl. Effect of the Invention

[0014] The head support device according to the present disclosure is attached to and detached from the edge of a shampoo bowl to support the head of a person to be treated, and has a base part attached to the edge of the shampoo bowl and a swinging part connected to the base part by a connecting structure, the swinging part has a first abutment part that abuts the back of the head or the vicinity of the back of the head, a protruding support part that stands up on the opposite side of the inside of the shampoo bowl from the first abutment part, and a second abutment part that is attached from the upper end side of the protruding support part to house the protruding support part inside and abuts the neck or the vicinity of the neck on the outside, the swinging part swings toward the inside or outside of the shampoo bowl relative to the base part, and the second abutment part swings toward the inside or outside of the shampoo bowl with the upper end of the protruding support part as a fulcrum. The second abutment part swings like a pendulum with the upper end of the protruding support part as a fulcrum, and since the protruding support part is contained inside the second abutment part, the swinging of the second abutment part is realized while the fulcrum of the swinging motion is shielded. That is, the head support device is structured so that the entire protruding support part, including the upper end of the protruding support part that serves as the fulcrum of the rocking motion, is shielded, so that it does not interfere with treatment, and is easy to clean as it does not get wet with hot water or treatment liquid. In addition, when a rod extending laterally is used as the rotation axis, the structure for supporting the rod generally becomes bulky in the horizontal direction, but the present disclosure uses the upper end of the protruding support part extending upward as the fulcrum of the rocking motion, so that it does not become bulky in the horizontal direction and is small. Furthermore, the rocking of the second abutment part and the rocking of the rocking part allow the head support device to adapt to the posture of the head of the person being treated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] In the head support device according to the present disclosure, the second contact portion is placed on the upper end of the protruding support portion and is detachable. That is, the head support device has a simple structure in which the second contact portion is simply placed on the upper end of the protruding support portion. Since the second contact portion can be easily attached and detached, there is no need to bother with attaching and detaching it for cleaning.

[0017] The head support device according to the present disclosure is configured with a pair of protruding support parts on the left and right sides intersecting the direction in which the second abutment part swings, and the second abutment part is recessed between the protruding support parts. The head of the patient is supported by the recessed second abutment part that is stretched between the protruding support parts, so the posture of the head is stabilized. In particular, the head is positioned lower than the upper end of the protruding support part that serves as the fulcrum for the swinging motion by the amount that the second abutment part is recessed, so the posture of the head is stabilized.

[0018] The head support device according to the present disclosure has a connecting structure that includes a pair of rails extending in the direction in which the swinging part swings, and a pair of shafts that are connected to each rail. The second contact part swings around the "point" of the upper end of the protruding support part as a fulcrum, whereas the swinging part swings along the "line" of the rail part. Therefore, the first contact part swings in the front-rear direction like a pendulum while changing the angle as the swinging part swings along the rail part, and is also displaced in the up-down direction, and the second contact part swings. Thus, the head support device can adapt to the posture of the head of the patient. The connecting structure is simple if it is the rail part and the shaft part.

[0019] In the head support device according to the present disclosure, the shaft portion protrudes from the inside of the rail portions through the rail portions toward the outside to the left and right sides. Therefore, compared to a case in which the shaft portion is passed through the rail portions from the outside of the rail portions, the connecting structure is not bulky in the lateral direction and is small. Therefore, the head support device has a structure that does not interfere with treatment.

[0020] In the head support device according to the present disclosure, the second contact portion has a cover portion that closes a concave neck rest space formed on the edge of the shampoo bowl for the neck of the recipient to pass through. The gap in the neck rest space is wider because of the small size of the head support device, but the gap is blocked by the cover portion. Moreover, regardless of the size of the head support device, even if the neck rest space is wide to begin with, the gap is blocked by the cover portion. Therefore, hot and cold water is prevented from splashing out of the gap in the neck rest space.

[0021] The beauty salon device according to the present disclosure includes a treatment table used by a person to be treated, a shampoo bowl disposed behind the backrest of the treatment table, and the head support device attached to the shampoo bowl, thereby achieving the same effects as the head support device described above.

[0022] Hereinafter, a head support device according to an embodiment of the present disclosure will be described with reference to the drawings. Figures 1 and 2 show a hairdressing and beauty device 1 equipped with a head support device 8 according to this embodiment. Figure 1 shows a state before treatment using a shampoo bowl 9 is performed, and Figure 2 shows a state in which treatment using the shampoo bowl 9 is possible.

[0023] As shown in Figs. 1 and 2, the hairdressing and beauty device 1 has a treatment table 2 used by a person to be treated (not shown) and a shampoo bowl 9 arranged behind the treatment table 2 on which the head of the person to be treated is placed. The treatment table 2 has a seat section 3 on which the person to be treated lies and a lifting section 4 supporting the seat section 3 from below. The seat section 3 has a seat section 5 on which the person to be treated sits, a leg rest section 6 connected to the front of the seat section 5 on which the legs of the person to be treated are placed, and a backrest section 7 connected to the rear of the seat section 5 on which the upper half of the person to be treated is placed. The seat section 3 may have armrest sections (not shown) arranged on the left and right sides of the seat section 5 on which the arms of the person to be treated are placed. The treatment table 2 has a seat section 3 that rises and falls as the lifting section 4 operates to expand and contract up and down, and the angle of the seat section 3 changes as the backrest section 7 reclines or rises. When the backrest section 7 reclines, the seat section 3 becomes horizontal or approximately horizontal. The posture of the treatment table 2 can be changed arbitrarily by being operated by a therapist (not shown), and can also be automatically changed to a predetermined posture.

[0024] The shampoo bowl 9 is for the person to be treated to place his / her head while lying on his / her back on the seat part 3 and receive the treatment. The therapist stands behind or on the left or right side of the shampoo bowl 9 (or sits on a stool) and performs treatment on the head and hair of the person to be treated. The treatment includes, for example, shampooing, scalp massage, coloring, perm, eye makeup, etc. The shampoo bowl 9 is placed on a base part 10. The shampoo bowl 9 is composed of a bottom part 14 and a peripheral wall part 15, and is roughly hemispherical. In the shampoo bowl 9, a drain port 11 is formed in the bottom part 14, and a stop valve 12 for hot water supply, a shower head 13 for discharging hot water, etc. are installed on the inner surface of the peripheral wall part 15. A part of the front edge of the peripheral wall part 15 facing the seat part 3 is recessed, forming a concave neck placement space 16. A head support device 8 is placed in the neck placement space 16. The head support device 8 is freely attached and detached. The neck and head of the person to be treated are placed on the head support device 8, and a part of the head support device 8 swings in accordance with the posture of the head.

[0025] Here, the head support device 8 will be described in detail with reference to the drawings. Figures 3 to 9 show the appearance and cross section of the head support device 8. In the following, among the directions in which the head support device 8 swings, the direction toward the inside of the shampoo bowl 9 is referred to as the front side, the direction toward the outside of the shampoo bowl 9 is referred to as the back side, the directions intersecting the front side and the back side directions are referred to as the right side and the left side, respectively, and the height directions are referred to as the upper side and the lower side (Up, Down) (see Figure 3).

[0026] As shown in Figs. 3 and 4, the head support device 8 has a base portion 17 attached to the edge of the shampoo bowl 9, and a swinging portion 24 connected to the base portion 17 by a connecting structure 32. The swinging portion 24 has a rail portion 26 constituting the connecting structure 32, a hemispherical first contact portion 27 that contacts the head of the person to be treated, a rod-shaped or thin plate-shaped protruding support portion 28 that stands up on the upper side, and a second contact portion 29 attached to the protruding support portion 28. The second contact portion 29 has a second contact main body portion 33 and a contact cover portion 36 that covers the second contact main body portion 33. As shown in Figs. 7 and 8, the first contact portion 27 swings in the front-rear direction together with the swinging portion 24, centering on a first swing fulcrum 45. The second contact portion 29 swings in the front-rear direction, centering on a second swing fulcrum 46 that is the upper end of the protruding support portion 28.

[0027] 3 to 6, the base portion 17 has a pair of left and right pedestal portions 18, and a rod-shaped base connection portion 19 that extends in the left-right direction between the two pedestal portions 18 and is connected to both pedestal portions 18. Each pedestal portion 18 has a generally circular and flat plate portion 20, a leg portion 21R (21L) that rises upward from the upper surface of the plate portion 20, and an axis portion 22R (22L) and buffer portions 23F, 23B attached to the leg portion 21R (21L). Therefore, the plate portion 20, the legs 21R, 21L, the axis portions 22R, 22L, and the buffer portions 23F, 23B are all configured as a pair on the left and right.

[0028] Each leg 21R (21L) has two shafts 22R (22L) and two buffers 23F, 23B. The shaft 22L attached to the left leg 21L protrudes leftward from the left side surface of the leg 21L. The shafts 22L are aligned in the front-rear direction, with the front shaft 22L being positioned slightly above the rear shaft 22L (see FIG. 6). One of the buffers 23F attached to the left leg 21L protrudes forward from the front side surface of the leg 21L, and the other of the buffers 23B attached to the left leg 21L protrudes rearward from the rear surface of the leg 21L. On the other hand, the shaft 22R attached to the right leg 21R protrudes rightward from the right side surface of the leg 21R. The shafts 22R are aligned in the front-rear direction, with the front shaft 22R being positioned slightly above the rear shaft 22R. One of the buffer parts 23F attached to the right leg 21R protrudes forward from the front side of the leg 21R, and the other buffer part 23B attached to the right leg 21R protrudes rearward from the rear surface of the leg 21R.

[0029] In the swinging part 24, the rail part 26, the first contact part 27 and the protruding support part 28 are configured as a pair on the left and right. The rail part 26 is formed at both ends of the main body part 25 that is long in the left and right direction. Each rail part 26 is formed by a hole penetrating in the left and right direction, extends in the front-rear direction in which the swinging part 24 swings, and curves along a circumference centered on the first swing fulcrum 45 (see FIG. 7). A front side regulating part 30 is formed between the rail parts 26 on the front side of the main body part 25, and a rear side regulating part 31 is formed between the rail parts 26 on the rear side of the main body part 25. Each first contact part 27 is disposed between the rail parts 26 and adjacent to each rail part 26, and is attached to the front side of the main body part 25. Each protruding support part 28 is disposed rearward of the first contact part 27 and attached directly behind each rail part 26.

[0030] The connecting structure 32 is composed of a pair of rail portions 26 of the swinging portion 24 and a pair of shaft portions 22R, 22L of the base portion 17. The legs 21R, 21L are disposed between the rail portions 26, and the shaft portions 22R, 22L pass through the rail portions 26 from the inside to the outside in a state in which the legs 21R, 21L and the rail portions 26 are adjacent to each other in the left-right direction. When the swinging portion 24 and the base portion 17 are connected by the connecting structure 32, the shaft portions 22R, 22L slide within the rail portions 26, causing the swinging portion 24 to swing in the front-rear direction relative to the base portion 17.

[0031] The second abutment body portion 33 is elongated in the left-right direction, and has flat front and rear surfaces. The second abutment body portion 33 has a pair of left and right insertion groove portions 34, and abutment body concave portions 35 connected to the respective insertion groove portions 34 between the respective insertion groove portions 34. The insertion groove portions 34 are formed at both left and right ends of the second abutment body portion 33, and the protruding support portions 28 of the first abutment portion 27 are inserted into the insertion groove portions 34. The abutment body concave portions 35 are upper ends of the second abutment body portion 33 between the insertion groove portions 34, and are recessed downward.

[0032] The abutting cover part 36 has a flat cover front part 37, a flat cover rear part 38, and a cover recessed part 39 connecting the upper end of the cover front part 37 and the upper end of the cover rear part 38. The cover front part 37 and the cover rear part 38 face each other with a gap therebetween. The cover recessed part 39 is the upper end of the abutting cover part 36 and is recessed downward. As shown in FIG. 9, the abutting cover part 36 may have a wide cover part 44. The wide cover part 44 is freely attached to and detached from the rear side surface of the cover rear part 38. The wide cover part 44 is thin plate-shaped and is formed wider than the width of the abutting cover part 36 in the left-right direction.

[0033] The shape of the inner surface of the contact cover portion 36 generally coincides with the shape of the outer surface of the second contact main body portion 33. Therefore, the front-to-rear thickness of the second contact main body portion 33 is a size that fits between the cover front surface portion 37 and the cover rear surface portion 38 of the contact cover portion 36, and the shape of the contact main body recessed portion 35 of the second contact main body portion 33 generally coincides with the shape of the cover recessed portion 39 of the contact cover portion 36.

[0034] The base part 17, the swinging part 24, the second abutment body part 33 and the abutment cover part 36 are assembled as follows. In Figs. 3 and 4, the base part 17 and the swinging part 24 are connected by the connecting structure 32. The abutment cover part 36 is attached to the second abutment body part 33. By being attached to the abutment cover part 36, the second abutment body part 33 is covered by the abutment cover part 36. By inserting the protruding support part 28 into the insertion groove part 34 of the second abutment body part 33, the second abutment part 29 covers the upper end part of the protruding support part 28 from above. Therefore, the second abutment part 29 is detachable from the protruding support part 28 in the vertical direction. It is also possible to attach the abutment cover part 36 to the second abutment body part 33 after the second abutment body part 33 is attached to the protruding support part 28.

[0035] 5, shafts 22R, 22L of base 17 protrude laterally to the left and right from the inside of rails 26 of swinging part 24 through rails 26 toward the outside. Protruding support part 28 of swinging part 24 is housed inside second abutment part 29, and protruding support part 28 is entirely covered and shielded by second abutment part 29. Therefore, connecting structure 32, protruding support part 28, etc. are not exposed at both left and right ends of head support device 8.

[0036] The assembled head support device 8 is placed in the neck placement space 16 of the shampoo bowl 9 and attached to the peripheral wall 15 (see Figs. 1 and 2). Specifically, the flat plate portion 20 of the base portion 17 is placed on the upper edge of the peripheral wall 15 and fixed to the peripheral wall 15 by passing bolts or the like through. Even if there is a gap between the peripheral wall 15 and the head support device 8 in the neck placement space 16, if the second contact portion 29 has the wide cover portion 44 (see Fig. 9), the gap will be blocked by the wide cover portion 44 (see Fig. 9).

[0037] Next, the operation, function and effects of the head support device 8 will be described together with the internal structure of the second contact portion 29.

[0038] As shown in Figs. 7 and 8, the insertion groove 34 of the second contact body 33 has an inner front surface facing portion 40 facing the front side of the protruding support portion 28 of the swinging portion 24, an inner rear surface facing portion 41 facing the rear side of the protruding support portion 28, and an inner supported portion 42 connected to the upper end of the inner front surface facing portion 40 and the upper end of the inner rear surface facing portion 41 and against which the upper end of the protruding support portion 28 abuts. A swinging space 43 surrounded by the inner front surface facing portion 40, the inner rear surface facing portion 41, and the inner supported portion 42 is formed inside the insertion groove 34. The swinging space 43 is wider than the protruding support portion 28. Therefore, the distance between the inner front surface facing portion 40 and the inner rear surface facing portion 41 is wider than the thickness of the protruding support portion 28 in the front-rear direction. In addition, the inner front surface facing portion 40 and the inner rear surface facing portion 41 are gradually separated from each other as they move downward from the inner supported portion 42. Therefore, the second abutment portion 29 swings in the front-rear direction with the upper end portion of the protruding support portion 28 as a second swing fulcrum 46. The angle of the inner rear facing portion 41 relative to the inner front facing portion 40 with the inner supported portion 42 as a fulcrum (this can also be rephrased as the angle of the inner front facing portion 40 relative to the inner rear facing portion 41 with the inner supported portion 42 as a fulcrum) and the distance between the inner front facing portion 40 and the inner rear facing portion 41 (the width of the swing space 43) are arbitrary.

[0039] The rail portion 26 of the swinging portion 24 is supported by the shaft portion 22L (22R) of the base portion 17, and slides along the shaft portion 22L (22R) within the range of the hole in the rail portion 26. The shaft portion 22L (22R) is arranged with a slight vertical offset, and the rail portion 26 is curved along a circumference centered on the first swing fulcrum 45, so the trajectory of the swinging portion 24 is arc-shaped. Therefore, the swinging portion 24 swings in an arc in the front-rear direction centered on the first swing fulcrum 45. Therefore, the first abutment portion 27 also swings in the front-rear direction centered on the first swing fulcrum 45 together with the swinging portion 24. When the swinging portion 24 swings forward and the rear-side regulating portion 31 hits the buffer portion 23B of the base portion 17, the swinging motion of the swinging portion 24 is regulated. Similarly, when the swinging portion 24 swings rearward and the front restricting portion 30 abuts against the buffer portion 23F of the base portion 17, the swinging motion of the swinging portion 24 is restricted.

[0040] When the head of the person to be treated is placed on the head support device 8 configured as described above, the first contact portion 27 comes into contact with the back of the head of the person to be treated or the vicinity of the back of the head. Since the second contact portion 29 is located on the opposite side of the inside of the shampoo bowl 9 from the first contact portion 27, the second contact portion 29 comes into contact with the neck of the person to be treated or the vicinity of the neck. The body sizes of the people to be treated vary, and the postures of the head during the treatment also vary. That is, the people to be treated may move their head downward by pulling their chin in, or may move their head upward as if looking up.

[0041] As described above, in the head support device 8, the second contact portion 29 swings like a pendulum with the upper end of the protruding support portion 28 as a "point" as a fulcrum, whereas the swing portion 24 swings along the rail portion 26 as a "line" (see Figs. 7 and 8). Therefore, as the swing portion 24 swings along the rail portion 26, the first contact portion 27 swings in the front-rear direction like a pendulum while changing the angle, and is also displaced in the up-down direction, and the second contact portion 29 also swings. Thus, the head support device 8 can adapt to the posture of the head of the patient. The rail portion 26 and the shaft portions 22R and 22L make the connecting structure 32 simple.

[0042] In head support device 8, protruding support part 28 of oscillating part 24 is housed inside second abutment part 29, and protruding support part 28 is entirely covered and shielded by second abutment part 29 (see FIG. 5). In other words, since protruding support part 28 is entirely shielded together with its upper end part which serves as second fulcrum 46 of the oscillating motion, this structure does not interfere with treatment, and is easy to clean as hot water or medical fluids used for treatment do not adhere to it.

[0043] Furthermore, shafts 22R, 22L of base 17 protrude laterally to the left and right from the inside between rails 26 of swinging section 24 through rails 26 toward the outside (see FIG. 5). Therefore, connecting structure 32, protruding support parts 28, etc. are not exposed at both left and right ends of head support device 8. Therefore, head support device 8 has a structure that does not interfere with treatment and is small in size.

[0044] In the head support device 8, the protruding support part 28 is inserted into the insertion groove part 34 of the second abutment main body part 33, so that the second abutment part 29 covers the upper end part of the protruding support part 28 of the swinging part 24 from above (see Figs. 7 and 8). That is, it is a simple structure in which the second abutment part 29 is simply placed on the upper end part of the protruding support part 28. Therefore, the second abutment part 29 can be easily attached and detached to the protruding support part 28, and there is no hassle of attaching and detaching it for cleaning.

[0045] In the head support device 8, the second contact body part 33 has the contact body concave part 35, and the contact cover part 36 has the cover concave part 39 (see FIG. 1), so that the head of the patient is supported by the concave second contact part 29 that is stretched between the protruding support parts 28. Therefore, the posture of the head is stabilized. In particular, since the cover concave part 39 is located below the upper end part of the protruding support part 28 that serves as the second swing fulcrum 46 of the swinging motion, the head is also positioned below the upper end part of the protruding support part 28, so the posture of the head is stabilized.

[0046] In the head support device 8, the second contact portion 29 has a wide cover portion 44 (see FIG. 9). Even if a gap is created between the peripheral wall portion 15 and the head support device 8 in the neck rest space 16 of the shampoo bowl 9, the gap is blocked and shielded by the wide cover portion 44. This prevents hot and cold water from splashing out from the gap in the neck rest space 16.

[0047] In another embodiment of the present disclosure, the protruding support portion is a single plate that is long in the left-right direction. In this case, the contact cover portion does not have a cover recess. In another embodiment, the connecting structure is a rotating shaft, and the swinging part swings around the rotating shaft.
