Description

half body bathtub

The present invention relates to a half-body bathtub that minimizes the size of the bathtub body and does not cause discomfort to the knees and legs when used.

Half-body bathing is a new health bathing method that has become popular recently. It is a bathing method that is contrasted with a full-body bathing method in which the whole body is immersed by immersing only the lower body below the solar plexus in hot tub water for a long period of time to improve blood circulation and sweating effects on the whole body.

As such half-body baths are known to be significantly effective in relieving fatigue as well as various diseases such as atopic dermatitis, menstrual irregularities, menstrual pain and menopausal disorders, the number of people enjoying half-body baths is increasing significantly.

However, unlike a full-body bath, a half-body bath is a perspiration bath in which only the lower body is immersed in hot water and sweating while sitting for a long time, so it is somewhat inconvenient to perform in a full-body bathtub and wastes a lot of hot water, so eventually, a sitting bathtub for half-body bathing of various designs equipped with a chair was created. began to be designed.

As an example, a half-body bathtub proposed through Korean Registered Utility Model Publication No. 20-0358020 is known, and the half-body bathtub has a seating surface formed at a certain height from the bottom of the bathtub and a backrest surface extending from the seating surface, and a seating surface. A leg holder is formed at the front of the surface to support the user's legs and feet below the knees, allowing the user to sit comfortably in the bathtub for a long time and enjoy a half-body bath.

However, if a half-body bathtub is manufactured with a high chair height as described above, the walls of the bathtub are high, making it very inconvenient to use.

This is because the height from the bottom of the bathtub to the seating surface is about 40cm based on the standard body size of a Korean adult. If you add 40cm of height to the solar plexus and 5cm of sleeping space, and add a certain distance between the bottom of the bathtub and the bathroom floor, the bathtub's Since the height is approximately 100cm or more, users will face significant difficulties in access and safety due to the high height of the bathtub.

If a bathtub in which the user sits upright were actually made as shown above, the height of the bathtub would be so high that the user would have to climb a ladder to enter and exit the bathtub, which would pose safety and practical problems, making it impossible to implement.

To solve this problem, as shown in Figure 1, various types of half-body bathtubs designed to lower the height of the seating surface and minimize the certain gap between the bottom of the bathtub and the bathroom floor have been developed.

The conventional half-body bathtub (1) described above is effective to some extent in that the height (H1) of the bathtub (20) is relatively lower than the conventional one, making entry and exit easier, but for a half-body bath with fresh water at the level of the solar plexus, the seating surface of the hips ( 21) As the height is made much lower than the knees, the back lies backward and the legs are extended forward to straighten the bent hip and knee joints. In order to implement a low half-body bathtub that is easy to enter and exit, the backrest surface 22 is formed to be inclined at the rear of the very low seating surface 21, and at the same time, the length of the leg holder 23 for extending the feet forward is ( Since L1) must also be lengthened, the height H1 of the bathtub 20 is lowered, while the length becomes longer than before.

In addition, as the front and back length of the seating surface 21 is shorter, the weight of the lower body, which cannot be supported by the seating surface 21, is transmitted to the legs through the knees, causing discomfort in the knees and legs.

Therefore, the half-body bathtub (1) described above is not only burdensome to use in a narrow bathroom due to its long length to the front, but also uncomfortable for the knees and legs due to the short seating surface (21). There were many requests for a comfortable half-body bathtub, so improvements were needed.

In other words, the wall height of a bathtub that is easy to enter should be about 60cm, the horizontal distance between the back and toes of an adult male when sitting on an ordinary chair should be about 90cm, so it should be easy to install for urban people with narrow bathrooms, and the low seating position should be about 25cm. This means that the user sitting on the surface (21) should not feel any discomfort even if he or she takes a half-body bath for a long time.

However, as seen above, when the wall of the bathtub 20 is lowered, the height of the seating surface 21 must be lowered for half-body bathing, and when the seating surface 21 is lowered, the legs must be stretched out, so the length of the leg holder 13 becomes longer. In order to make the bathtub as small as possible, the shorter the leg holder (13) and the seating surface (21), the better, but the shorter it is, the more uncomfortable it is for the knees and legs. As such, the above problems are very difficult to solve because they are contradictory conditions that are difficult to reconcile.

The present invention was conceived to solve the above-mentioned problems, and its purpose is to provide a half-body bathtub that is low in height and easy to enter and exit, is minimal in size without increasing the length in the front, and does not cause discomfort to the user's knees and legs. .

In order to achieve the above object, the half-body bathtub of the present invention includes a bathtub body, a pair of holders detachably mounted on the left and right walls of the bathtub body, and both ends are detachably coupled to the holders to support the user's thigh area. It includes a thigh support with a support bar.

Additionally, the bathtub body may be provided with a flange portion that extends to be bent downwardly outward along the top of the left and right walls.

In this case, the holder includes a body portion that is in close contact with the inside of the left and right walls of the bathtub body, an upper support portion that extends from the top of the body toward the flange portion of the bathtub body and is supported on the top of the flange portion, and an outer end of the upper support portion. It may be provided with a side end support portion extending downwardly from and supported on the outer surface of the flange portion.

In addition, in order to adjust the height of the support bar, fitting holes spaced apart in the vertical direction may be formed in the body of the holder, and fitting protrusions that fit into the fitting holes may be formed at both ends of the support bar.

Additionally, the fitting hole may have a circular shape whose diameter becomes smaller as it goes downward.

In this case, the fitting protrusion of the support bar may include an arc-shaped connecting portion supported at the lower end of the fitting hole, and an arc-shaped close contact end extending outward along the connecting portion to be in close contact with the rear surface of the fitting hole. .

Meanwhile, it is preferable that at least one receiving groove for accommodating the upper support portion of the holder is formed at the upper end of the flange portion.

In this case, the upper support portion and the receiving groove may each have a corresponding semicircular shape.

On the other hand, the holder extends from the bottom of the side end support toward the wall of the bathtub body, has a lower support part supporting the bottom of the flange part, and extends upward from the lower support part and is located between the flange part and the wall of the bathtub wall. A locking step may be provided.

In this case, the vertical width of the flange portion may increase toward the center of the bathtub body.

Since the present invention configured as described above is provided with a thigh support that is detachably mounted on the left and right walls of the bathtub body, the user not only feels comfortable with the lower body as a significant part of the lower body weight is supported on the thigh support, but also the leg part below the knee. Since there is no need to extend the legs forward while naturally moving backward, there is an effect of reducing the front-to-back length of the leg rest.

Due to this, the present invention lowers the height of the bathtub body compared to the prior art and reduces the front and rear length of the leg holder, thereby dramatically reducing the size of the bathtub, making it convenient to use as a half-body bathtub for many urban people with narrow bathrooms, and allowing users to reduce water usage. It is economical because it can save a lot, and it can be expected to contribute to the energy-saving green movement through saving hot water.

The half-body bathtub of the present invention includes a bathtub body, a pair of holders detachably mounted on the left and right walls of the bathtub body, and a thigh support having a support bar that is detachably coupled to both ends of the holder to support the user's thigh area. Includes.

Hereinafter, when an embodiment of the present invention is described in detail with reference to the drawings, the same symbols are used for the same components, and for clarity, only the different parts are mainly described to avoid overlap as much as possible.

Figure 2 is a perspective view of a half-body bathtub according to the present invention, Figure 3 is an exploded perspective view of a half-body bathtub according to the present invention, Figure 4 is a cross-sectional view taken along line IV-IV of Figure 2, and Figure 5 is a side view of the half-body bathtub in use according to the present invention. As shown in the cross-sectional view, the half-body bathtub of the present invention consists of a bathtub body 100 and a thigh support 200.

The bathtub body 100 is made of synthetic resin, and has a seating surface 110 inclined downwardly toward the rear, a backrest surface 120 so that one can sit on the seating surface 110 and lean back, and the seating surface ( A leg holder 130 is formed in front of 110) to support the user's legs and feet below the knee.

Since the seating surface 110 is formed to slope downwardly toward the rear, the user can enjoy a half-body bath in a very comfortable position by leaning back against the backrest surface 120 with the buttocks deeply buried.

In addition, when the seating surface 110 is formed to slope downwardly toward the rear, the knees do not touch the front of the bathtub 110 even if the front-to-back length (L2) of the leg holder 130 is designed to be narrower than before, so the front and back of the bathtub 110 It is possible to manufacture by minimizing the size.

In addition, when the seating surface 110 is formed to slope downwardly toward the rear, the height of the seating surface 110 goes down and the height H2 of the bathtub 110 can be minimized.

In addition, since not only the buttocks but also the backs of the thighs are mounted on the seating surface 110, the front-to-back length (L2) of the leg holder 130 can be designed to be narrower, and the sitting feeling is naturally improved.

Meanwhile, the bathtub body 100 may be provided with a flange portion 140 that extends to be bent downwardly outward along the top of the left and right walls.

The flange portion 140 is not only used as a handle when transporting the bathtub body 100, but also prevents safety accidents resulting from cuts on the top of the thin bathtub body 100 when used.

The thigh support 200 is mounted on the left and right walls of the bathtub body 100.

The thigh support 200 includes a pair of holders 210 detachably mounted on the left and right walls of the bathtub body 100, and both ends are detachably coupled to the holders 210 to support the user's thigh area. A support bar (220) is provided.

The holder 210 has a body portion 211 that is in close contact with the inside of the left and right walls of the bathtub body 100, and extends from the top of the body portion 211 toward the flange portion 140 of the bathtub body 100 to form the planar portion. It includes an upper support portion 212 supported on the upper end of the branch 140, and a side end support portion 213 extending downward from the outer end of the upper support portion 212 and supported on the outer surface of the flange portion 140. can do.

When the holder 210 is configured as described above, even if the weight of the user's thigh area acts downward on the body part 211, it is possible to maintain a stable position without being separated from the flange part 140.

In consideration of this, the holder 210 is preferably made of metal or synthetic resin material with excellent strength and corrosion resistance so as to be able to withstand the weight of the user's thigh area.

The support bar 220 is removable at both ends from the holder 210 across the leg holder 130 to the left and right at a position spaced upward from the seating surface 110 so as not to put excessive pressure on the user's thigh area. are combined together.

Considering this, the support bar 220 is preferably made of metal or synthetic resin material with excellent strength and corrosion resistance so as to be able to withstand the weight of the user's thigh area.

In addition, the support bar 220 is preferably formed in a shape with a long side that contacts the user's thigh area, and is preferably formed to slope upward toward the front.

In this case, the user does not feel excessive pressure on the thigh area, so the user can always enjoy a half-body bath in comfort without pain or decreased blood circulation in the thigh area.

Although not shown, the surface of the section of the support bar 220 that comes into contact with the user's thigh area may be made of a cushion material.

In this embodiment, the support bar 220 is shown and described as having a rectangular cross-section as an example, but it is not necessarily limited to this and may have various cross-sectional shapes.

Meanwhile, fitting holes 216 spaced apart in the vertical direction are formed in the body portion 211 of the holder 210 so that the height of the support bar 220 can be adjusted because the user's height or body shape is different, and the support bar Fitting protrusions 221 that fit into the fitting holes 216 may be formed at both ends of 220 .

Since the insertion protrusion 221 must withstand the weight of the user's thigh area, it goes without saying that it must be manufactured to have sufficient strength.

In this case, the fitting hole 216 may have a circular shape whose diameter becomes smaller as it goes downward. In addition, the fitting protrusion 221 of the support bar 220 is in close contact with the arc-shaped connecting part 221a supported at the lower end of the fitting hole 216 and the rear surface of the fitting hole 216. It may be provided with an arc-shaped close contact end (221b) extending outward along .

Accordingly, the user can easily mount the support bar 220 on the holder 210 by simply placing the fitting protrusion 221 of the support bar 220 on the fitting hole 216, and the user can easily mount the support bar 220 on the holder 210 in close contact with the support bar 220. Due to the stage 221b, the mounted state is maintained stably without floating.

In addition, when the user simply lifts the mounted support bar 220 while the support bar 220 is mounted, the fitting protrusion 221 is separated from the fitting protrusion 221 and the support bar 220 is placed on the holder ( Since it can be easily separated from 210, the attachment and detachment operation of the support bar 220 can be easily performed.

Meanwhile, a receiving groove 141 for accommodating the upper support part 212 of the holder 210 is provided at the top of the flange part 140 to prevent the holder 210 from moving forward and backward along the flange part 140. It is desirable to form

The receiving grooves 141 may be formed in plural numbers at regular intervals so that the position of the holder 210 can be adjusted according to the user's body size.

In this case, the upper support portion 212 and the receiving groove 141 may each have a corresponding semicircular shape.

When the upper support portion 212 and the receiving groove 141 are formed in a semicircular shape, the thigh support 200 naturally rotates according to the external force transmitted from the user's thigh, so the user can always assume a comfortable posture.

The half-body bathtub of the present invention configured as described above is used as follows.

First, place the thigh stand 200 on the bathtub body 100 and then adjust the position of the stand 210 so that the support bar 220 of the thigh stand 200 is located at the thigh area.

At this time, it is desirable to position the support bar 220 at a point spaced upward from the seating surface 110 to prevent excessive pressure from being applied to the thigh area.

In this way, when the thigh support 200 is mounted on the bathtub body 100, the user sits with his/her knees placed on the support bar 220, and the support bar 220 supports the front of the thigh while holding the armchair. Like the long seat of , the seating surface 110 has the effect of expanding forward, and at the same time, the user's body weight is distributed to the support bar 220, allowing the user to enjoy a half-body bath in a more comfortable position.

In addition, when the user sits down with his knees placed on the support bar 220, his knees naturally move up and approach the chest. Accordingly, the legs and feet below the knee also naturally move backward along the knee, so the user does not need to extend the leg forward, and as a result, the front-to-back length (L2) of the leg holder 130 can be further reduced. There will be.

Therefore, the present invention makes it possible to implement the height (H2) of a bathtub that is easy to enter and exit at about 60cm, and the horizontal distance between the back and toes of an adult male when sitting on an ordinary chair is reduced to about 90cm, making it easier for urban people with narrow bathrooms to provide one. Lose.

In addition, the seating surface 110 is formed as low as 25 cm from the floor, so that the user does not feel uncomfortable even if he or she takes a half-body bath for a long time.

In this way, when the height (H2) of the bathtub body 100 is lowered, the height of the seating surface 110 must be lowered for half-body bathing, and when the seating surface 110 is lowered, the legs must be stretched out, so the leg holder 130 A contradiction arises that is difficult to reconcile with the need for the front and back lengths to be longer, but the present invention solves this problem by introducing the principle of the seat of an armchair.

The seat of the armchair is comfortable as it supports the thighs of the seated person in a long upward direction. However, it is not possible to install a long seat in a half-body bathtub. Instead, the support bar 220, which functions as a long seat, is installed above the short seating surface 110 to provide the above-mentioned comfort. The contradiction was overcome and resolved. If the support bar 220 is positioned spaced apart from the front of the seating surface 110 rather than in close contact with it, it can support the weight of the thigh area like the seat of an armchair, thereby providing comfort to the user.

Meanwhile, as shown in FIGS. 6 and 7, the holder 210 extends from the bottom of the side end support portion 213 toward the wall of the bathtub body 100 to support the bottom of the flange portion 140. It may be provided with a lower support portion 214 that extends upward from the lower support portion 214 and a locking protrusion 215 located between the flange portion 140 and the wall surface of the bathtub wall.

In this case, the vertical width (D) of the flange portion 140 may increase toward the center of the bathtub body 100, and the receiving groove 141 formed in the flange portion 140 may be excluded.

Therefore, the holder 210 can be easily mounted on the flange portion 140 at the front or rear of the wall of the bathtub body 100 and then easily slidably moved to the center of the bathtub body 100. As the lower support portion 214 of the holder 210 comes into close contact with the bottom of the flange portion 140, the holder 210 can be mounted stably without moving.

In addition, the holder 210 is reliably prevented from being separated from the flange portion 140 by the locking protrusion 215.

Considering this, it is preferable that the vertical width D of the flange portion 140 at the point corresponding to the user's thigh region is formed to be the same length as the vertical width of the side end support portion 213 of the holder 210. .

As such, although preferred embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments, and modifications may be made by those skilled in the art without departing from the spirit of the present invention. It is possible, and it is obvious that such modifications fall within the scope of the present invention.

The half-body bathtub of the present invention can be easily used by people of all ages and genders at home.
