Abstract
Description
Shampoo bowls and beauty equipment
[0001] The present disclosure relates to a shampoo bowl and a beauty treatment device.
[0002] Conventionally, hair salons and other beauty salons have provided hairdressing chairs (hereinafter referred to as the "Publication 1 Invention") as devices used for treatments such as shampooing and scalp massages, such as those described in Patent Document 1 below. The Publicly Known Publication 1 Invention includes a chair on which the person receiving treatment sits and a shampoo bowl installed behind the chair. When the chair back is reclined, the person's head is placed in the shampoo bowl, and the therapist massages the person's head from inside the shampoo bowl.
[0003] During the treatment, the practitioner may stand to the side of the shampoo bowl and treat the patient's head from the side, but in recent years, there has been an increase in practitioners standing behind the shampoo bowl and treating the patient's head from the top (hereinafter referred to as "back shampoo").
[0004] JP 2008-104846 A
[0005] However, shampoo bowls come in a variety of shapes. For example, the invention in the first publication is generally oval, while others are rectangular. However, the shape of a shampoo bowl that is particularly suitable for back shampooing has not yet been established. In other words, the invention in the first publication does not take into consideration the size, shape, etc. that are easy for the practitioner to use when performing back shampooing.
[0006] The present disclosure has been proposed in consideration of the above-described circumstances, and aims to provide a shampoo bowl and a beauty and hairdressing device designed with a size and shape suitable for back shampooing.
[0007] In order to achieve the above-mentioned object, the shampoo bowl of the present disclosure has a treatment space surrounded by a bottom and a peripheral wall portion rising from the periphery of the bottom, and the peripheral wall portion has a neck placement wall portion on which the neck of the person to be treated is placed, corner wall portions connected to the left and right sides of the neck placement wall portion, a top wall portion on the opposite side of the neck placement wall portion with respect to the treatment space, and side wall portions connected to the corner wall portion and the top wall portion, and is characterized in that, compared to a virtual top wall portion in which the curvature of the top wall portion is smaller than the curvature of the side wall portion, the top wall portion curves in an arc and protrudes outward, and the curvature of the top wall portion is formed to be larger than the curvature of the side wall portion.
[0008] The shampoo bowl according to the present disclosure is characterized in that the corner wall portions and the side wall portions are curved outward in an arc shape, and the curvature of the peripheral wall portion increases in the order of the corner wall portion, the top wall portion, and the side wall portion.
[0009] The shampoo bowl according to the present disclosure is characterized in that the height of the side wall portion is the same as the height of the head support device attached to the neck placement wall portion.
[0010] The shampoo bowl according to the present disclosure is characterized in that the distance from the upper end of the neck placement wall portion to the upper end of the corner wall portion is longer than the distance from the upper end of the neck placement wall portion to the bottom.
[0011] The shampoo bowl of the present disclosure is characterized in that the distance from the installation portion where the shower head is installed to the bottom is longer than the distance from the installation portion to the upper end of the top wall portion.
[0012] The hairdressing and beauty device according to the present disclosure is characterized by having a treatment table used by the person receiving treatment, and the above-mentioned shampoo bowl positioned behind the backrest of the treatment table.
[0013] The shampoo bowl according to the present disclosure has a treatment space surrounded by a bottom and a peripheral wall portion rising from the periphery of the bottom. The peripheral wall portion has a neck placement wall portion where the neck of the person to be treated is placed, corner wall portions connected to the left and right sides of the neck placement wall portion, a top wall portion on the opposite side of the neck placement wall portion with respect to the treatment space, and side wall portions connected to the corner wall portion and the top wall portion. Compared to a hypothetical top wall portion where the curvature of the top wall portion is smaller than that of the side wall portion, the top wall portion curves outward in an arc shape, and the curvature of the top wall portion is greater than that of the side wall portion. A shower head is located inside the top wall portion. The treatment space is expanded by the amount of the top wall portion's protrusion. When a practitioner performs treatment from behind the top wall, the treatment space expands toward the practitioner, making it particularly suitable for back shampooing.
[0014] FIG. 1 is a perspective view of a hairdressing device having a shampoo bowl according to an embodiment of the present disclosure in a non-treatment state. FIG. 2 is a side view of a hairdressing device having a shampoo bowl according to an embodiment of the present disclosure in a non-treatment state. FIG. 3 is a perspective view of a hairdressing device having a shampoo bowl according to an embodiment of the present disclosure in a treatment state. FIG. 4 is a side view of a hairdressing device having a shampoo bowl according to an embodiment of the present disclosure in a treatment state. FIG. 5 is a perspective view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 6 is a top view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 7 is a bottom view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 8 is a front view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 9 is a side view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 10 is a rear view of a shampoo bowl according to an embodiment of the present disclosure. FIG. 11 is a cross-sectional side view of a shampoo bowl according to an embodiment of the present disclosure, taken along line XI-XI of FIG. 8.
[0015] In the shampoo bowl according to the present disclosure, the corner wall portions and side wall portions are curved in an arcuate shape outward, with the curvature of the peripheral wall portions increasing in the order of corner wall portion, top wall portion, and side wall portion. This configuration results in a roughly triangular shape for the peripheral wall portions. The portions of the side wall portions near the top wall portion are narrower than the corner wall portions, and are therefore closer to the patient's head. During back shampooing, the practitioner places their arms on the side wall portions, and because the portions where their arms are placed are closer to the patient's head, the practitioner can place their arms on the side wall portions while grasping the patient's head with their hands. If the peripheral wall portions of the shampoo bowl were horizontally oval or rectangular, the curvature of the peripheral wall portions would be smaller near the top of the head, and therefore the peripheral wall portions would not be close to the patient's head. Therefore, when the practitioner grasps the patient's head with their hands during back shampooing, the peripheral wall portions will contact the patient's elbows, and this posture is not suitable for the practitioner during back shampooing.
[0016] In the shampoo bowl according to the present disclosure, the height of the side wall matches the height of the head support device attached to the neck placement wall. When the therapist places their arm on the side wall and grasps the head of the person being treated with their hand, the arm posture is generally straight, so that by rotating the wrist, the hand can reach the top or back of the head.
[0017] In the shampoo bowl according to the present disclosure, the distance from the top of the neck wall to the top of the corner wall is longer than the distance from the top of the neck wall to the bottom. During back shampooing, the therapist starts from the top of the person's head, so hot and cold water from the shower head splashes onto the neck wall and the corner wall. In the present disclosure, the corner wall is high, preventing hot and cold water from overflowing the corner wall.
[0018] The shampoo bowl according to the present disclosure has a longer distance from the installation portion where the shower head is installed to the bottom than from the upper end of the top wall. In back shampooing, the therapist starts from the top of the head, so it is convenient if the treatment space on the top wall side, which is closer to the therapist's hands, is wide. On the other hand, if the top wall is high, it becomes difficult for the therapist to reach the treatment space. The present disclosure has a low top wall and a deep bottom, making it suitable for back shampooing.
[0019] The beauty salon apparatus according to the present disclosure includes a treatment table used by a patient and the shampoo bowl disposed behind the backrest of the treatment table, thereby achieving the same effects as the shampoo bowl.
[0020] A shampoo bowl according to an embodiment of the present disclosure will be described below with reference to the drawings. Figures 1 to 4 show a hairdressing and beauty device 1 equipped with a shampoo bowl 9 according to this embodiment. Figures 1 and 2 show the hairdressing and beauty device 1 in a non-treatment state, which is a state before treatment using the shampoo bowl 9 is performed, and Figures 3 and 4 show the hairdressing and beauty device 1 in a treatment state, which is a state in which treatment using the shampoo bowl 9 is possible. Note that, hereinafter, in the hairdressing and beauty device 1, the direction toward the treatment table 2 is referred to as the front side (Front), the direction toward the shampoo bowl 9 is referred to as the back side (Back), the sides are referred to as the right side and the left side, respectively, and the height direction is referred to as the upper side and the lower side (Up, Down) (see Figure 1).
[0021] As shown in Figures 1 to 4, the hairdressing and beauty device 1 includes a treatment table 2 used by a person (not shown) to be treated 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.
[0022] The shampoo bowl 9 is designed for a person to place their head while lying face up on the seat 3 and receive a treatment. The therapist stands behind 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, 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 side of the peripheral wall 15 facing the seat 3 is recessed, and a head support device 8 is attached to the recess. The head support device 8 is detachable and can be freely attached. The person's neck and head are placed on the head support device 8.
[0023] The shampoo bowl 9 will now be described in detail with reference to the drawings. Figures 5 to 11 show the appearance and cross section of the shampoo bowl 9.
[0024] 5 to 11, the shampoo bowl 9 has a bottom 14 and a peripheral wall 15 that rises from the periphery of the bottom 14. The inside of the shampoo bowl 9, surrounded by the bottom 14 and the peripheral wall 15, is a treatment space where the head of the person to be treated is placed. The shampoo bowl 9 is symmetrical with respect to a center line 35 in the front-to-rear direction (see FIG. 6).
[0025] The peripheral wall 15 has a neck placement wall 16 that forms the front side of the peripheral wall 15, corner wall portions 17 that form the front of the left and right sides of the peripheral wall 15 and are connected to the left and right sides of the neck placement wall 16, a top wall portion 18 that forms the rear side of the peripheral wall 15 and is located on the opposite side of the neck placement wall 16 with respect to the treatment space, and side wall portions 19 that form the left and right sides of the peripheral wall 15 and are connected to the corner wall portion 17 and the top wall portion 18. The peripheral wall 15 is divided into an upper peripheral wall portion 20 that forms the upper side and a lower peripheral wall portion 21 that forms the lower side, and the upper and lower peripheral wall portions 20, 21 are connected at different levels. The treatment space of the lower peripheral wall portion 21 is narrower than that of the upper peripheral wall portion 20, and the treatment space of the upper peripheral wall portion 20 is wider than that of the lower peripheral wall portion 21. The upper and lower peripheral wall portions 20, 21 are inclined outward as they extend upward.
[0026] The neck placement wall 16 is formed lower than other portions of the peripheral wall 15, forming a concave neck placement space on the edge of the shampoo bowl 9 for the recipient's neck to pass through. A front flat surface 22 is formed at the upper end of the neck placement wall 16 ( FIG. 11 ). The front flat surface 22 is a flat surface that protrudes outward. The front end of the front flat surface 22 protrudes slightly upward. The inner side of the neck placement wall 16, bounded by the front flat surface 22, constitutes a part of the lower peripheral wall 21, and the outer side, bounded by the front flat surface 22, constitutes a part of the upper peripheral wall 20. The head support device 8 is attached to and detached from the front flat surface 22. Thus, the recipient's neck is placed on the front flat surface 22 via the head support device 8.
[0027] The corner wall 17 is formed higher than the neck placement wall 16, and the upper end of the corner wall 17 is above the front flat surface 22 of the neck placement wall 16. The corner wall 17 extends upward and gently slopes outward. A side wall step 23 is formed on the side wall 19. The side wall step 23 protrudes outward and has a stop valve 12 and other components mounted on its upper surface. The inner side of the side wall 19, bounded by the side wall step 23, forms part of the lower peripheral wall 21, and the outer side of the side wall step 23 forms part of the upper peripheral wall 20. The top wall 18 is formed with a rear flat surface 24 as a mounting portion for the shower head 13. The rear flat surface 24 is a flat surface that protrudes outward, and the shower head 13 is mounted on it. The shower head 13 is located on the center line 35 of the shampoo bowl 9. The rear flat surface 24 is connected to the side wall step 23. The inner side of the top wall 18, bounded by the rear flat surface 24, forms part of the lower peripheral wall 21, and the outer side of the top wall 18, bounded by the rear flat surface 24, forms part of the upper peripheral wall 20.
[0028] As shown in Figure 6, in the upper peripheral wall portion 20, the side wall portions 19 are connected at the rear via the top wall portion 18, and are connected at the front via both corner walls 17 to both ends of the neck arrangement wall portion 16. The top wall portion 18 is on the center line 35 and faces the center of the neck arrangement wall portion 16. Therefore, the shampoo bowl 9 has a generally triangular shape with the single top wall portion 18 and the two corner walls 17 as vertices. The top wall portion 18, corner walls 17, and side walls 19 of the upper peripheral wall portion 20 are curved outward in an arc-like shape, so the triangular shape is rounded. The curvatures of the first curved portion 26, the second curved portion 27, and the third curved portion 28 of the upper peripheral wall portion 20 are greatest in the order of corner wall portion 17, top wall portion 18, and side wall portion 19 (curvature of first curved portion 26 > curvature of second curved portion 27 > curvature of third curved portion 28). Here, top wall portion 18 protrudes outward from imaginary top wall portion 25 in a hypothetical case where the curvature of second curved portion 27 of top wall portion 18 is smaller than the curvature of third curved portion 28 of side wall portion 19. In other words, top wall portion 18, which is triangular in shape, protrudes outward in comparison with a portion corresponding to the top wall in a hypothetical case where shampoo bowl 9 is shaped like a horizontally elongated oval.
[0029] When viewed from above, the corner wall 17 of the upper peripheral wall 20 protrudes outward beyond the neck placement wall 16, but the corner wall 17 of the upper peripheral wall 20 has a first curved portion 26 at its upper end with a different curvature than the fourth curved portion 29 at its lower end. More specifically, as shown in Figure 7, the curvature of the fourth curved portion 29 at the lower end of the corner wall 17 is smaller than the curvature of the first curved portion 26 at the upper end. Therefore, when viewed from below, the neck placement wall 16 protrudes outward beyond the corner wall 17 at the periphery of the lower end of the upper peripheral wall 20. That is, the upper peripheral wall portion 20 slopes outwardly as it extends upward, and the corner wall portion 17 also slopes outward as it extends upward, so that its upper end protrudes outward beyond the neck placement wall portion 16. As a result, the curvature of the first curved portion 26 at the upper end of the corner wall portion 17 differs from the curvature of the fourth curved portion 29 at the lower end of the corner wall portion 17. Note that in Figures 6 and 7, the first curved portion 26, the second curved portion 27, the third curved portion 28, and the fourth curved portion 29 indicate only a specific point, but the curvatures of the first curved portion 26, the second curved portion 27, the third curved portion 28, and the fourth curved portion 29 do not refer to the curvature of the specific point shown. The curvatures of the respective portions 26, 27, 28, and 29 are within an appropriate range of the corner wall portion 17, the top wall portion 18, and the side wall portion 19.
[0030] 11 , a distance 31 from the front flat surface 22 to the upper end of the corner wall 17 is longer than a distance 30 from the upper end (front flat surface 22) of the neck placement wall 16 to the bottom 14. Also, a distance 33 from the rear flat surface 24 to the bottom 14 is longer than a distance 32 from the rear flat surface 24 on which the showerhead 13 is installed to the upper end of the top wall 18.
[0031] As shown in Figures 10 and 11, the height of the side wall portion 19 near the top wall portion 18 and the height of the ball portion 8a of the head support device 8 attached to the neck placement wall portion 16, on which the nape and back of the head of the patient are placed, are roughly the same (see line 34 in the figure).
[0032] The present embodiment is configured as described above. Next, the effects of the present embodiment will be described.
[0033] As described above, in this embodiment, the top wall 18 of the upper peripheral wall 20 protrudes outward beyond the imaginary top wall 25, and the curvature of the second curved portion 27 of the top wall 18 is greater than the curvature of the third curved portion 28 of the side wall 19 (see FIG. 6 ). Therefore, the treatment space is wider by the amount that the top wall 18 protrudes. For a practitioner positioned behind the top wall 18, the treatment space expands toward the practitioner, making this suitable for back shampooing.
[0034] In this embodiment, the upper peripheral wall 20 has a single top wall 18 and two corner wall 17 as vertices. The curvatures of the first curved portion 26, the second curved portion 27, and the third curved portion 28 of the upper peripheral wall 20 increase in the order of the corner wall 17, the top wall 18, and the side wall 19 (curvature of the first curved portion 26 > curvature of the second curved portion 27 > curvature of the third curved portion 28). The top wall 18, the corner wall 17, and the side wall 19 are curved outward in an arc-like shape, forming a rounded triangular shape (see FIG. 6 ). The area near the top wall 18 is narrower than the corner wall 17, and is therefore closer to the user's head. During back shampooing, the practitioner places their arm on the side wall 19, and because the area where the arm is placed is closer to the user's head, the practitioner can place their arm on the side wall 19 while holding the user's head with their hand.
[0035] In this embodiment, the height of the side wall 19 near the top wall 18 is generally the same as the height of the ball portion 8a of the head support device 8 attached to the neck placement wall 16 (see FIGS. 10 and 11). When the therapist places his / her arm on the side wall 19 and grasps the head of the patient with his / her hand, the posture of the arm is generally straight, so that by rotating the wrist, the hand can reach the top or back of the head.
[0036] In this embodiment, the distance 31 from the front flat surface 22 to the upper end of the corner wall 17 is longer than the distance 30 from the upper end (front flat surface 22) of the neck placement wall 16 to the bottom 14 (see Figures 10 and 11). In a back shampoo, the therapist performs the shampoo from the top of the head of the person being treated, so hot and cold water from the shower head 13 splashes onto the neck placement wall 16 and the corner wall 17, but the high corner wall 17 prevents the hot and cold water from splashing over the corner wall 17.
[0037] In this embodiment, the distance 33 from the rear flat surface 24 to the bottom 14 is longer than the distance 32 from the rear flat surface 24 on which the shower head 13 is installed to the upper end of the top wall 18 (see Figures 10 and 11). In back shampooing, the therapist begins the treatment from the top of the head, so it is convenient if the treatment space on the top wall 18 side, which is the side closest to the therapist's hands, is wide. On the other hand, if the top wall 18 is high, it becomes difficult for the therapist to reach the treatment space. In this embodiment, the top wall 18 is low and the bottom 14 is deep, making it suitable for back shampooing.
[0038] In other embodiments of the present disclosure, the curvature of the side wall and the corner wall may be any, as long as the top wall of the upper peripheral wall protrudes outward beyond the imaginary top wall and the curvature of the top wall is greater than the curvature of the side wall. Another embodiment does not include a head support device. In this case, the neck of the non-practitioner is placed directly on the front flat surface of the neck placement wall. In another embodiment, the height of the side wall near the top does not match the height of the bowl portion of the head support device attached to the neck placement wall, on which the nape of the neck or the occipital region of the patient is placed. In another embodiment, the height of the side wall near the top does match the height of the bowl portion of the head support device attached to the neck placement wall, on which the nape of the neck or the occipital region of the patient is placed. In another embodiment, the distance from the front flat surface to the upper end of the corner wall is shorter than the distance from the top end (front flat surface) of the neck placement wall to the bottom. In another embodiment, the distance from the upper end (front flat surface) of the neck placement wall to the bottom is approximately the same as the distance from the front flat surface to the upper end of the corner wall. In another embodiment, the distance from the rear flat surface to the bottom is shorter than the distance from the rear flat surface to the upper end of the top wall. In another embodiment, the distance from the rear flat surface to the upper end of the top wall is approximately the same as the distance from the rear flat surface to the bottom.
[0039] Although the embodiments of the present disclosure have been described in detail above, the present disclosure is not limited to the above embodiments, and various design modifications can be made to the present disclosure without departing from the scope of the claims.
