Description

head support device

[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 receiving treatment.

[0002] Conventionally, hair salons and other beauty salons have provided portable shampoo bowls as devices used for shampooing, scalp massage, and other treatments, for example, as described in Patent Document 1. This shampoo bowl is equipped with a head support device for supporting the head of the person receiving treatment.

[0003] In the head support device, a member for supporting the back of the head of the patient (the head support base in Patent Document 1) is suspended via a rotation shaft between a pair of left and right columnar members, and a member for supporting the neck of the patient (the neck rest in Patent Document 1) is suspended via a rotation shaft between the head support bases. When the patient's head is placed in the head support device, both members swing via the two rotation shafts in response to the head's posture. Therefore, the head support device can flexibly adapt to the patient's posture.

[0004] JP 2017-77378 A

[0005] However, in the head support device described above, 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 nape of the neck, hindering treatment. Also, cleaning the rotating shaft is cumbersome.

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

[0007] In order to achieve the above-mentioned object, the head support device of the present disclosure is a head support device that is attached and detached to the edge of a shampoo bowl to support the head of a person being treated, and has a base portion that is attached to the edge of the shampoo bowl, and a oscillating portion that is connected to the top of 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 opposite side of 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 house the protruding support portion inside and the outside of which abuts 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, using 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 the upper end of the protruding support portion and is detachable.

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

[0010] The head support device according to the present disclosure is characterized in that the connecting structure is composed of a pair of rail sections extending in the direction in which the oscillating section oscillates, and a pair of shaft sections connected to each of the rail sections, each of which is composed of a pair of shaft sections.

[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 according to the present disclosure is characterized by having a treatment table used by the person being treated, a shampoo bowl positioned behind the backrest of the treatment table, and a head support device as described in claim 1 or claim 2 attached to the shampoo bowl.

[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 receiving treatment, and includes a base attached to the edge of the shampoo bowl and a swinging part connected to the base by a connecting structure, the swinging part having 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 rises upward on the opposite side of the shampoo bowl from the inside of the first abutment part, and a second abutment part attached to the upper end side of the protruding support part to house the protruding support part inside and abutting 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, 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 because the protruding support part is housed inside the second abutment part, the second abutment part swings toward the inside or outside of the shampoo bowl In other words, the head support device is structured so that the entire protruding support portion, including its upper end, which serves as the fulcrum for the swinging 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 liquids. Furthermore, when a horizontally extending rod or the like is used as the rotation axis, the structure for supporting the rod generally increases the horizontal bulk. However, in the present disclosure, the upper end of the upwardly extending protruding support portion serves as the fulcrum for the swinging motion, so it does not increase the horizontal bulk and is compact. Furthermore, the swinging of the second abutment portion and the swinging of the swinging portion allows the head support device to adapt to the posture of the patient's head.

FIG. 4 is an exploded perspective view of a head support device according to an embodiment of the present disclosure. FIG. 5 is a front view of a head support device according to an embodiment of the present disclosure. FIG. 6 is a side view of a head support device according to an embodiment of the present disclosure. FIG. 7 is a cross-sectional side view of a head support device according to an embodiment of the present disclosure, taken along line VII-VII of FIG. 5. FIG. 8 is a cross-sectional side view of a head support device according to an embodiment of the present disclosure, but in a different position from FIG. 7. FIG. 9 is a perspective view of a head support device according to an embodiment of the present disclosure, with a cover member attached.

[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. Because the second contact portion can be easily attached and detached, there is no need for the hassle of attaching and detaching it for cleaning.

[0017] The head support device according to the present disclosure is configured with a pair of protruding support portions on the left and right sides intersecting the direction in which the second abutment portions swing, and the second abutment portions are recessed between the protruding support portions. The patient's head is supported by the recessed second abutment portions that are stretched between the protruding support portions, thereby stabilizing the head posture. In particular, the head is positioned lower than the upper ends of the protruding support portions, which serve as the fulcrum for the swinging motion, by the amount that the second abutment portions are recessed, thereby stabilizing the head posture.

[0018] The head support device according to the present disclosure has a connecting structure that includes a pair of rails extending in the direction of the swinging of the swinging portion, and a pair of shafts connected to each of the rails. While the second contact portion swings around a "point" that is the upper end of the protruding support portion as a fulcrum, the swinging portion swings along a "line" that is the rail portion. Therefore, as the swinging portion swings along the rail portion, the first contact portion swings in the front-to-back direction like a pendulum, changing its angle, and also displaces in the up-to-down direction, while the second contact portion swings. This allows the head support device to adapt to the posture of the patient's head. The rails and shafts provide a simple connecting structure.

[0019] In the head support device according to the present disclosure, the shafts protrude laterally from the inside of the rails, through the rails, and outward. Therefore, compared to when the shafts are passed through the rails from the outside, the connecting structure is not bulky in the lateral direction and is compact. 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 the recessed neck rest space formed on the edge of the shampoo bowl for the recipient's neck to pass through. Because the head support device is small, the gap in the neck rest space is large, but the cover portion shields the gap. Furthermore, regardless of the size of the head support device, even if the neck rest space is large to begin with, the cover portion shields the gap. Therefore, splashing of hot water through the gap in the neck rest space is prevented.

[0021] The beauty treatment device according to the present disclosure includes a treatment table used by the patient, 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] A head support device according to an embodiment of the present disclosure will now be described with reference to the drawings. Figures 1 and 2 show a beauty salon apparatus 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 ready.

[0023] As shown in Figures 1 and 2, the hairdressing and beauty treatment device 1 includes a treatment table 2 used by a person (not shown) and a shampoo bowl 9 located behind the treatment table 2 and on which the person's head is placed. The treatment table 2 includes a seat 3 on which the person lies and a lifting unit 4 supporting the seat 3 from below. The seat 3 includes a seat 5 on which the person sits, a leg rest 6 connected to the front of the seat 5 and on which the person's legs are placed, and a backrest 7 connected to the rear of the seat 5 and on which the person's upper body is placed. The seat 3 may also include armrests (not shown) located on the left and right sides of the seat 5 and on which the person's arms are placed. The treatment table 2 is configured such that the seat 3 rises and falls as the lifting unit 4 operates to expand and contract vertically, and the backrest 7 tilts or rises to change the angle of the seat 3. When the backrest 7 is tilted, the seat 3 is horizontal or approximately horizontal. The posture of the treatment table 2 can be changed arbitrarily by operation by a therapist (not shown), or can be automatically changed to a predetermined posture.

[0024] The shampoo bowl 9 is designed for a person to lie face up on the seat 3 and place their head there to receive a treatment. A therapist stands behind or to the left or right of the shampoo bowl 9 (or sits on a stool) and performs treatments on the person's head and hair. Treatments include, for example, shampooing, scalp massage, coloring, perming, and eye makeup. The shampoo bowl 9 is placed on a base 10. The shampoo bowl 9 is generally hemispherical and comprises a bottom 14 and a peripheral wall 15. A drain outlet 11 is formed in the bottom 14 of the shampoo bowl 9, and a hot water stop valve 12 and a shower head 13 for discharging hot water are installed on the inner surface of the peripheral wall 15. A portion of the front edge of the peripheral wall 15, facing the seat 3, is recessed to form a concave neck rest space 16. A head support device 8 is disposed in the neck rest 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. Note that, hereinafter, among the directions in which the head support device 8 swings, the direction toward the inside of the shampoo bowl 9 will be referred to as the front side (Front), the direction toward the outside of the shampoo bowl 9 will be referred to as the back side (Back), directions intersecting the front side and back side directions will be referred to as the left and right sides (Right Side, Left Side), respectively, and the height direction will be referred to as the upper side and lower side (Up, Down) (see Figure 3).

[0026] As shown in Figures 3 and 4, the head support device 8 includes a base 17 attached to the edge of the shampoo bowl 9 and a swinging unit 24 connected to the base 17 by a connecting structure 32. The swinging unit 24 includes a rail 26 constituting the connecting structure 32, a hemispherical first contact portion 27 that contacts the head of the user, a rod-shaped or thin-plate-shaped protruding support portion 28 that rises upward, and a second contact portion 29 attached to the protruding support portion 28. The second contact portion 29 includes 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 Figures 7 and 8, the first contact portion 27 swings back and forth together with the swinging unit 24 around a first swing fulcrum 45. The second contact portion 29 swings back and forth around a second swing fulcrum 46, which is the upper end of the protruding support portion 28.

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

[0028] Each leg 21R (21L) has two axles 22R (22L) and two buffers 23F, 23B. The axle 22L attached to the left leg 21L protrudes leftward from the left side surface of the leg 21L. The axles 22L are aligned front to back, with the front axle 22L positioned slightly higher than the rear axle 22L (see FIG. 6). One buffer 23F attached to the left leg 21L protrudes forward from the front side surface of the leg 21L, and the other buffer 23B attached to the left leg 21L protrudes rearward from the rear surface of the leg 21L. Meanwhile, the axle 22R attached to the right leg 21R protrudes rightward from the right side surface of the leg 21R. The axles 22R are aligned front to back, with the front axle 22R positioned slightly higher than the rear axle 22R. One of the buffer parts 23F attached to the right leg 21R protrudes forward from the front surface 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 unit 24, the rail portions 26, first abutment portions 27, and protruding support portions 28 are configured as a pair on the left and right. The rail portions 26 are formed at both ends of the main body portion 25, which is elongated in the left-right direction. Each rail portion 26 is formed by a hole penetrating in the left-right direction, extends in the front-rear direction, which is the direction in which the swinging unit 24 swings, and curves along a circumference centered on the first swing fulcrum 45 (see FIG. 7 ). A front restricting portion 30 is formed between the rail portions 26 on the front side of the main body portion 25, and a rear restricting portion 31 is formed between the rail portions 26 on the rear side of the main body portion 25. Each first abutment portion 27 is disposed between the rail portions 26 and adjacent to the respective rail portions 26, and is attached to the front side of the main body portion 25. Each protruding support portion 28 is disposed rearward of the first abutment portion 27 and attached directly behind the respective rail portions 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 with the legs 21R, 21L and the rail portions 26 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-to-rear direction relative to the base portion 17.

[0031] The second abutment main body portion 33 is elongated in the left-right direction and has flat front and rear surfaces. The second abutment main body portion 33 has a pair of left and right insertion groove portions 34 and abutment main body recessed portions 35 connected to each of the insertion groove portions 34 between the insertion groove portions 34. The insertion groove portions 34 are formed on both left and right ends of the second abutment main 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 main body recessed portions 35 are the upper end portions of the second abutment main body portion 33 between the insertion groove portions 34 and are recessed downward.

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

[0033] The shape of the inner surface of the contact cover portion 36 generally matches 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 large enough to fit 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 matches the shape of the cover recessed portion 39 of the contact cover portion 36.

[0034] The base 17, the swinging part 24, the second abutment body 33, and the abutment cover 36 are assembled as follows. In Figures 3 and 4, the base 17 and the swinging part 24 are connected by the connecting structure 32. The abutment cover 36 is attached to the second abutment body 33. By attaching the abutment cover 36 to the second abutment body 33, the second abutment body 33 is covered by the abutment cover 36. By inserting the protruding support part 28 into the insertion groove 34 of the second abutment body 33, the second abutment part 29 covers the upper end 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 36 to the second abutment body 33 after the second abutment body 33 is attached to the protruding support part 28.

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

[0036] The assembled head support device 8 is placed in the neck rest 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 with bolts or the like. Even if there is a gap between the peripheral wall 15 and the head support device 8 in the neck rest space 16, if the second abutment portion 29 has a wide cover portion 44 (see FIG. 9), the gap will be closed 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] 7 and 8 , the insertion groove 34 of the second contact main body 33 has an inner front-face-facing portion 40 that faces the front side of the protruding support portion 28 of the swinging portion 24, an inner rear-facing portion 41 that faces the rear side of the protruding support portion 28, and an inner supported portion 42 that is connected to the upper end of the inner front-face-facing portion 40 and the upper end of the inner rear-facing portion 41 and against which the upper end of the protruding support portion 28 abuts. A swing space 43 surrounded by the inner front-face-facing portion 40, the inner rear-facing portion 41, and the inner supported portion 42 is formed inside the insertion groove 34. The swing space 43 is wider than the protruding support portion 28. Therefore, the distance between the inner front-face-facing portion 40 and the inner rear-facing portion 41 is wider than the thickness of the protruding support portion 28 in the front-to-rear direction. Furthermore, the inner front-face-facing portion 40 and the inner rear-facing portion 41 gradually increase in distance from the inner supported portion 42 downward. Therefore, the second abutment portion 29 swings in the front-rear direction with the upper end 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-face-facing portion 40 with the inner supported portion 42 as a fulcrum (this can also be rephrased as the angle of the inner front-face-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-face-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 positioned 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-to-rear direction around the first swing fulcrum 45. Therefore, the first abutment portion 27 also swings in the front-to-rear direction together with the swinging portion 24 around the first swing fulcrum 45. When the swinging portion 24 swings forward and the rear-side restricting portion 31 abuts against the buffer portion 23B of the base portion 17, the swinging motion of the swinging portion 24 is restricted. 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 movement 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. People of various sizes and head postures during treatment vary. That is, the person to be treated may tuck their chin and move their head downward, 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 serving as a fulcrum, while the swinging portion 24 swings along the rail portion 26, which serves as a line (see FIGS. 7 and 8 ). Therefore, as the swinging portion 24 swings along the rail portion 26, the first contact portion 27 swings in the front-to-back direction like a pendulum, changing its angle, and is also displaced in the up-and-down direction, and the second contact portion 29 also swings. Therefore, the head support device 8 can adapt to the posture of the patient's head. The rail portion 26 and the shaft portions 22R, 22L provide a simple connecting structure 32.

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

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

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

[0045] In the head support device 8, the second contact body portion 33 has a contact body recessed portion 35, and the contact cover portion 36 has a cover recessed portion 39 (see FIG. 1 ), so that the patient's head is supported by the recessed second contact portion 29 that is stretched between the protruding support portions 28. This stabilizes the posture of the head. In particular, since the cover recessed portion 39 is located below the upper end of the protruding support portion 28, which serves as the second swing fulcrum 46 of the swinging motion, the head is also positioned below the upper end of the protruding support portion 28, which stabilizes the posture of the head.

[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 formed between the peripheral wall portion 15 and the head support device 8 in the neck resting space 16 of the shampoo bowl 9, the wide cover portion 44 closes and shields the gap. This prevents hot water from splashing out of the gap in the neck resting 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 abutment cover portion does not have a cover recess. In another embodiment, the connecting structure is a rotation axis, and the swinging portion swings around the rotation axis. In another embodiment, a rail portion is formed on the leg of the base portion, and a shaft portion is formed on the swinging portion. In another embodiment, the second abutment portion is connected to the upper end of the protruding support portion. In other words, the second abutment portion is not simply placed on the upper end of the protruding support portion. In another embodiment, the second abutment portion is not recessed. In this case, the second abutment main body portion does not have a contact main body recess and is flat, and the abutment cover portion does not have a cover recess and is flat.
