Description

  The present invention relates to a bus board installed at a part of an opening of a bathtub in order to facilitate bathing by an elderly person or a care recipient, and in particular, a part of the bus board having a specially shaped front edge is provided. The present invention relates to a bath board that is pivotable and is disposed at a position where the pivot member does not overlap the upper surface of the bathtub side wall.

  2. Description of the Related Art Conventionally, a bath board that is installed in a part of an opening of a bathtub has been provided in order to facilitate bathing for physically handicapped persons such as elderly people and care recipients (Patent Document 1). Such a bath board is passed over a part of the opening of the bathtub when a user such as an elderly person or a care recipient takes a bath, and the user sits on the bath board while the user is sitting on the bath board. By moving from the outside to the inside or from the inside to the outside, entering and exiting the bathtub is facilitated.

  In addition, since the bus board is in the way of the user's bathing, in recent years, the entire body of the bus board has been rotated so that the bus board can be flipped up while the user is bathing (patented) Document 2), or a bus board in which a part of the bus board body can be rotated has been developed (Patent Documents 3 and 4).

  However, in recent years, for users such as elderly people and care recipients, handrails are often provided on the side wall of the bathroom adjacent to the bathtub and directly above the side wall of the bathtub. For this reason, when the bath board is closed, as shown in Patent Documents 2 and 3, in the type of the bus board in which a part of the pivotable stool part overlaps the upper surface part of the bathtub side wall, the stool part jumps. When trying to raise, there is a problem that the stool portion interferes with a handrail attached to the side wall of the bathroom, and the stool portion cannot be substantially lifted up. In addition, since the stopper of the pivotable stool part is the upper surface part of the bathtub side wall, if the bath board is used for a long time and the stool part is repeatedly opened and closed, the upper surface part of the bathtub side wall may be damaged. .

  In particular, in the bus board of the type described in Patent Document 3, the shape of the lid frame that rotatably supports the seating plate is such that the concave opening portion is formed to expand forward from the back. If the lid frame does not cover the upper surface of the bathtub side wall, there is no specific restriction other than that, and when trying to raise the seat plate, the seat plate is attached to the bathroom side wall as described above. There is a problem that the seat cannot be raised substantially.

  Moreover, since a bus board is arrange | positioned and used under a user's body or behind a body, there exists a seat board which can be rotated in a part of bus board as described in patent document 4. The user must confirm the position and rotate the seat plate. However, when the user tries to visually confirm the position of the stool plate, the user must take an unnatural posture by bending his waist or twisting his body backwards. It is grasped by the feeling of the palm of the person.

  However, since the bath board described in Patent Document 4 is used as a part of the lid of the bathtub, the side edge of the front edge of the seat plate and the side piece of the lid frame so as not to create a gap with the other lid. Therefore, the user cannot confirm the position of the seating plate depending on the feeling of the palm or the like. Further, when the front edge of the stool is formed in a straight line like the bus board described in Patent Document 4, the user's hand is guided to the end (corner) of the front rim of the stool. When tilting up the raised stool, between the edge (corner) of the stool and the upper surface of the bathtub side wall or the edge (corner) of the stool and the edge of the lid frame (corner) There was also a problem that a hand was caught between.

  Furthermore, in the bus board described in Patent Document 4, a stopper for supporting the seat back diagonally when the seat is raised must be provided on the lid frame so that the seat can be used as a headrest. . For this reason, in the bus board described in Patent Document 4, a lid frame having a width equal to or greater than the thickness of the bathtub side wall must be disposed behind the seat plate, which increases the weight of the bath board. There was also a problem.

  Therefore, the present invention is a bath board installed in a bathtub to facilitate bathing by elderly people or care recipients, and a part of the bath board can be opened and closed, and a handrail is provided on the side wall of the bathroom. The installed bath board can be opened and closed even in a bathtub as provided, and the user can safely open and close the bus board without relying on visual inspection. An object of the present invention is to provide a bath board that does not damage the upper surface of the bathtub side wall even if the above is repeated.

  The present inventors, the shape and structure of the rotating portion of the bath board, the mounting manner of the bath board to the bathtub opening, the positional relationship between the bath board and the rotating portion, the bathtub side wall, the bathroom side wall, the handrail, etc. As a result of intensive research on the movement of the user's body on the bath board and the opening / closing operation of the bath board by the user, the rotating part provided on the bath board is positioned so as not to overlap the upper surface of the bathtub side wall. It has been found that the above-mentioned problems can be solved by adopting a shape and structure that can be arranged, and by making the front edge of the rotating portion a specific shape, and the present invention has been completed.

  That is, according to the present invention, the support base material placed on the upper surface of the bathtub side wall, and the left and right end portions have a front edge portion in which a concave portion that is curved rearward than the center portion is formed, In addition, in the bus board composed of a plate-like rotating member that is rotatably attached to the support base material, the rotating member is in a plan view when the bus board is attached to the upper surface of the bathtub side wall. A bath board is provided, wherein the bath board is disposed at a position not overlapping with an upper surface of a left side wall and / or an upper surface of a right side wall of the bathtub side wall.

  Further, according to the present invention, in plan view, the support base material placed on the upper surface of the bathtub side wall so as to cover the upper surface of the bathtub side wall, and the substantially straight left edge and the right side facing each other A plate-like circuit having an edge portion and a front edge portion in which a left and right end portion is formed with a concave portion curved backward from the center portion, and is rotatably attached to the support base material. In the bus board comprising a moving member, the left edge portion and the right edge portion of the rotating member are disposed inside the support base material when the rotating member is closed. A bus board is provided.

  Here, in the bus board of the present invention, “front” corresponds to the free end side of the rotating member of the bus board, and “rear” corresponds to the supporting end side of the rotating member of the bus board. Therefore, “left” corresponds to one end side in a direction perpendicular to the direction connecting the front and rear of the rotating member, and “right” refers to the other end located on the opposite side of the left. It corresponds to the department side. Since the bus board of the present invention is basically fixed to one corner of the bathtub, the front of the bus board corresponds to the inner side of the bathtub, and the rear of the bath board corresponds to the outer side of the bathtub. Further, the left side of the bath board corresponds to the washing room side of the bathtub or the side wall side of the bathroom, and the left side of the bath board corresponds to the side wall side of the bathroom or the washing room side of the bathtub.

  The material used for the bus board of the present invention is not particularly limited as long as it has the strength required for each component, and is a plastic material, a metal material, a wooden material, a fiber material, or a composite material combining them. Etc. can be used. However, since the inside of the bathroom is a severe corrosive environment of high temperature and humidity, it is preferable to use a plastic material having high corrosion resistance and light weight as a main material for the bath board.

  The support base member forms a part of the stool portion of the bath board, functions to fix the bus board to the side wall of the bathtub, and to rotatably support a rotating member described later. For this reason, if a support base material can be mounted in the upper surface of a bathtub side wall, what has plate shape, rod shape, or the shape which combined them can be used. However, in consideration of stability when the bath board is installed on the bathtub side wall, avoidance of damage to the upper surface of the bathtub side wall, convenience for the user, etc., the support base material is preferably plate-like, and When placed on the upper surface, it preferably has a width that can be completely covered so as to hide the upper surface of the bathtub side wall in plan view.

  Moreover, it is preferable that the support base material has a shape that can be arranged along the upper surface shape of the bathtub side wall. Therefore, the support base material is at least a left side base material placed on the left side wall of the bathtub. And a right side base material placed on the right side wall. In this case, when the left side base material and the right side base material are placed on the top surface of the bathtub side wall, they are completely covered so as to hide the top surface of the left side wall and the right side wall of the bathtub in plan view. It is preferable to have a width that can be

  In general, a handrail provided on the side wall of the bathroom is installed so as to protrude from the side wall of the bathroom to the inside of the side wall of the bathtub over the upper surface of the bathtub side wall in order to facilitate attachment / detachment or opening / closing of the bathtub lid. There is almost nothing. For this reason, when the bath board is placed on the upper surface of the bathtub side wall, the supporting base material, or the left side base material and the right side base material can completely cover the upper surface of the bathtub side wall in a plan view. If it has a width, the pivoting member of the bath board arranged inside can be freely opened and closed without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall. Become. Further, when the supporting base material, or the left side base material and the right side base material have a width that can cover the upper surface of the bathtub side wall, the rotating member does not come into contact with the upper surface of the bathtub side wall. Therefore, even if it opens and closes repeatedly, the upper surface of the bathtub side wall is not damaged.

  In order to improve the rigidity when the bath board is attached to the bathtub, the left side base material and the right side base material are preferably connected to each other by the rear side base material. That is, since the upper surface of one corner of the bathtub side wall usually has a U-shape or U-shape, the left side base material and the right side base material are also rear side in accordance with the top shape of the bathtub side wall. It is preferable that the base material is connected so as to form a substantially U shape or a substantially U shape.

  Further, when the left side base material and the right side base material are connected via the rear support base material, the left side base material, the right side base material and the rear side base material are As long as it can be placed on the upper surface, it is possible to select one having a plate shape, a rod shape, or a combination thereof. For example, a support base material can be configured by connecting a plate-like left side base material and a right side base material made of a plastic material with a rod-like rear side base material made of a metal material. For example, a plate-like left side base material and a right side base material can be integrally formed as a support base material made of the same plastic material by connecting them with a plate-like rear side base material.

  In order to improve the strength of the supporting base material by connecting the left side base material and the right side base material mainly unlike the left side base material and the right side base material. Since it functions, it does not necessarily have a width that can be completely covered so as to hide the upper surface of the rear side wall of the bathtub in plan view.

  The rear base material of the support base material has a front edge portion, and a plate-like rotating member in which concave portions curved rearward from the central portion are formed at the left and right end portions of the front edge portion. Is pivotally attached. Furthermore, the recessed part formed in the front edge part of the rotation member may curve back rather than the front-end part of the support base material arrange | positioned on each outer side. Since the bath board of the present invention can flip up the rotating member disposed in the opening of the bathtub, it does not disturb the user during bathing.

  The front edge portion of the rotating member has a concave portion that is curved rearward of the central portion at the left and right end portions thereof, so that the user does not have to bend the waist or twist the body backward and visually observe the palm. The position (concave portion) of the left and right end portions of the rotating member can be confirmed by the touch of the above. Also, if the concave portion is cut out to fit the user's palm, when the user opens and closes the rotating member, the palm is naturally guided to the concave portion of the rotating member. The rotating member can be safely opened and closed without a hand being sandwiched between the member and the bathtub side wall or between the rotating member and the support base.

  For this reason, the left shelf and the right shelf for supporting the bus board from the lower side when the rotating member is closed protrudes inward of the left side substrate and the right side substrate of the bus board. It is installed. Also, the front edge of the left shelf is arranged so as to be flush with or located behind the front edge of the recess of the rotating member when the rotating member is closed, and to the right The front edge portion of the side base material is disposed so as to be flush with or located rearward of the front edge portion of the recess of the rotation member when the rotation member is closed.

  In particular, when the rotating member is closed, the front edge of the left shelf and the front edge of the right shelf are arranged so as to be located behind the recess of the rotating member. Even if the user's hand that grips the moving member is turned to the back surface of the rotating member in the recess, the user's hand is between the rotating member and the left shelf, It can prevent effectively that it is pinched | interposed between right side shelf parts.

  In addition to the front edge, the rotating member preferably further includes a substantially straight left edge and a right edge facing each other in a direction substantially perpendicular to the front edge. The support base of the bath board, or the left side base and the right side base have a width that can cover the upper surface of the bathtub side wall, and the left and right edges of the rotating member Is formed so as to be along the inner edge of the support base, so that when the rotary member is closed, the left and right edges of the rotary member are attached so as to be disposed inside the support base. . Therefore, the left and right edges of the rotating member can freely open and close the rotating member without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall. Become.

  Further, when the bath board is mounted on the upper surface of the bathtub side wall, the rotating member of the bath board is arranged at a position that does not overlap with the upper surface of the left side wall and / or the upper side surface of the right side wall in plan view. You can also. Generally, the handrail provided on the side wall of the bathroom is hardly installed so as to protrude from the side wall of the bathroom to the inside of the bathtub side wall beyond the upper surface of the bathtub side wall in order to easily open and close the lid. Therefore, when the bath board is attached to the upper surface of the bathtub side wall, the rotating member is disposed at a position that does not overlap with the upper surface of the left side wall and / or the upper surface of the right side wall of the bathtub side wall in plan view. Can be opened and closed freely without interfering with the handrail attached to the bathroom side wall adjacent to the bathtub side wall. In addition, since the rotating member does not come into contact with the upper surface of the bathtub side wall, the upper surface of the bathtub side wall is not damaged even if it is repeatedly opened and closed.

  Well-known techniques such as hinges and ball joints can be adopted as the turning means of the turning member, and there is no particular limitation. Further, the rotating member may be attached to the rear side base material in the supporting base material, or the left side base material is sandwiched between the left side base material and the right side base material from both sides thereof. And may be rotatably supported on the right side base material.

  The bus board of the present invention has a left stopper that is slidable in the width direction of the left side base material on the lower surface of the left side base material, and that can be brought into contact with the inner surface of the bathtub side wall. It is preferable that the lower surface of the side base material is provided with a right side stopper that is slidable in the lateral width direction of the right side base material and that can be brought into contact with the inner surface of the bathtub side wall.

  The structure of the stopper is not particularly limited as long as it can be slidably moved in the width direction on the lower surface of the left side base material or the lower surface of the right side base material and can be fixed at a predetermined position. is not. For example, the stoppers described in Patent Documents 1 to 3 can be used as a stopper for the bus board of the present invention. In the bus board of the present invention, the support base of the bath board can be easily and firmly attached to the side wall of the bathtub by the frictional force of both stoppers by bringing the left and right stoppers into contact with the inner surface of the bathtub side wall. it can.

  In the bus board of the present invention, it is preferable that the upper surface of the rotating member is formed to be substantially flush with the upper surface of the supporting base material when the rotating member is closed.

  When the rotating member is closed, the upper surface of the support base and the upper surface of the rotating member are formed to be substantially flush with each other, and the user does not separate the buttock from the upper surface of the bath board. Since it can move smoothly from outside to inside or from inside to outside, it is safer and easier to enter and exit the bathtub.

  The bus board of the present invention preferably includes a knob having a substantially flat support surface for supporting the palm of the user on the upper surface of the rotating member.

  The bath board is originally placed over a part of the opening of the bathtub, and a person with a physical disability, such as an elderly person or a person requiring care, sits on the bath board from the outside of the bathtub. Used to move in or out. However, the degree of inconvenience of the user's body varies widely, and some users may use the bus board like a handrail and straddle the side wall of the bathtub in an upright position. In this case, the user faces the bath board and puts his hand on the upper surface of the bath board to straddle the side wall of the bathtub. For this reason, if a knob is provided on the upper surface of the bus board, the user can securely deposit a part of his / her weight on the bus board by putting his hand on the knob, so it is safe and easy. It becomes possible to straddle the side wall of the bathtub in a standing state.

  For this reason, it is preferable that a substantially flat support surface is formed on the upper surface of the knob. Since elderly people and those who need care often do not have sufficient grip strength, if a substantially flat support surface is provided on the top surface of the knob, the user can put the palm, back of the hand or fist on the support surface of the knob. You can leave a part of your weight on the bus board without putting your hand on it. As a result, the user can cross over the side wall of the bathtub in a safer and more easily standing position. For this reason, the knob is preferably substantially circular in plan view. By making the shape of the top surface of the knob or the entire shape of the knob into a substantially circular shape in plan view, the user can easily access the knob from any direction. A part can be deposited on the bus board.

  Moreover, in order to make it easy to support a user's palm, back of a hand, or a clenched fist stably, the support surface of the knob may be formed with a recess recessed from the side to the center. Moreover, when it is disliked that a water | moisture content accumulates on the support surface of a knob, the convex part which swelled toward the center from the side surface may be formed.

  When the support surface of the knob is recessed from the side surface toward the center, it is preferable to provide a drain hole or a drain groove for preventing moisture from accumulating on the support surface of the knob. In particular, when a drainage groove is provided on the support surface of the knob, it is preferable to provide at least one groove portion having a bottom surface bulging from the side surface toward the center. In this case, the water accumulated on the support surface of the knob is guided to the groove, and the water accumulated on the support surface is drained from the vicinity of the center of the knob to the side opening through the groove. The groove also functions to prevent the user from slipping on the support surface when the user places the palm, back of the hand, or fist on the support surface of the knob. For this reason, a plurality of grooves may be provided on the support surface of the knob in a lattice shape or a radial shape.

  The knob is composed of a grip part that is accessed by the user's hand, and a support part for attaching the grip part to the upper surface of the rotating member, and the maximum cross-sectional area of the horizontal section of the grip part is the support part. It is preferable that it is larger than the maximum cross-sectional area of the horizontal cross section. In this case, the support surface formed on the upper surface of the knob matches the upper surface of the grip portion.

  If the knob consists of a grip part and a support part, and the maximum cross-sectional area of the horizontal cross section of the grip is larger than the maximum cross-sectional area of the horizontal cross-section of the support part, even the user who has insufficient grip strength will Since a finger can be easily hooked, a part of his / her weight can be deposited in the grip portion in a more stable state.

  Moreover, in the bus board of this invention, it is preferable that the grip part is attached to the upper surface of a bus board via one support | pillar part. When the grip part is supported by a single support part, the user can easily grasp the grip part from any direction or place a fist on the grip part without choosing a position to access the grip part. A part of the body weight can be deposited in the grip portion, and the strength of the entire knob is improved, so that safe use by the user is guaranteed.

  Further, it is preferable that the outer peripheral portion of the grip portion is provided with a side surface having substantially the same width for a user to hang a finger, and the side surface of the grip portion is connected to the support surface by a continuous curved surface. If the outer periphery of the grip part is formed with side surfaces of approximately the same width, the user can easily grip the grip part from any direction, and the side surface of the grip part is supported by a continuous curved surface. When connected to the surface, the fit of the grip portion to the palm of the user is also improved. For this reason, as long as the side surface of a grip part has the substantially same width | variety, it may have a substantially flat shape in side view, and may have a shape which bulged a little outside.

  The knob is preferably attached to a position near the front edge of the rotating member of the bus board and a position near the left end and / or a right end of the rotating member. . For example, if the user uses the bus board to move mainly in a sitting position, the knob is attached to a position near the front edge of the rotating member and opposite to the washing area side. For example, if the user uses the bus board in a standing position with his / her hand mainly placed, the knob is located near the front edge of the rotating member and on the side opposite to the washing area side. Or a position near the front edge, and is preferably attached at a position on the washing area side and a position on the opposite side.

  When the user straddles the side wall of the bathtub in a standing position using the bath board, the user faces the bath board and puts his hand on the knob of the bath board and straddles the side wall of the bathtub. Therefore, the knob is attached at a position near the front edge of the turning member of the bus board and at a position near the left end and / or a right end of the turning member. Then, the user can easily access the knob and can support his / her body. In addition, when the user tries to enter or leave the bathtub while sitting on the bath board, the user can easily move his / her body using the knob.

  In addition, if the knob is located near the front edge of the rotating member, the user who sits on the bus board only lifts the knee slightly even when the knob is attached to the washroom side. Since the user can get over the knob together with the side wall of the bathtub, the knob does not become an obstacle when the user tries to enter or leave the bathtub in the sitting position. Further, since the knob is attached to the rotating member, not the support base material, the opening and closing of the rotating member is facilitated by using the knob. In addition, since the front edge of the rotating member is separated from the rotating shaft, the user can open and close the rotating member with a smaller force than when the knob is mounted near the rotating shaft. become.

  In the bus board of the present invention, it is preferable that the knob mounting position on the bus board can be changed / moved in accordance with the physique of the user. For this reason, the knob is provided with first engaging means such as a male screw, and a plurality of second engaging means such as female screws (screw holes) are provided on the upper surface of the rotating member. By installing and selecting the second engaging means to be engaged with the first engaging means, the knob mounting position can be changed / moved.

  Further, the knob can be slidably attached to the upper surface of the rotating member, whereby the knob attachment position can be continuously changed / moved in a stepless manner. In this case, the structure of the slide mechanism of the knob is not particularly limited as long as the knob can be slidably moved on the upper surface of the rotating member and can be fixed at a predetermined position. For example, it is also possible to divert the stopper slide mechanism described in Patent Documents 1 to 3 as a knob slide mechanism.

  According to the bus board of the present invention, it has a width that facilitates bathing of the elderly and care recipients and the support base material can be completely covered so as to hide the upper surface of the bathtub side wall, or Since the rotating member of the bath board is arranged at a position that does not overlap the upper surface of the bathtub side wall, the rotating member of the bath board can be opened and closed even in a bathtub where a handrail is provided on the side wall of the bathroom. It can also be opened and closed repeatedly without damaging the upper surface of the bathtub side wall.

  According to the bus board of the present invention, the front edge portion of the rotating member is formed with a concave portion whose left and right end portions are curved backward from the center portion, so that the user can bend his waist or face his body backwards. The position (recessed portion) of the left and right ends of the rotating member can be confirmed by touch of the palm, etc. without twisting it, and between the rotating member and the bathtub side wall or between the rotating member and the supporting base material The rotating member can be safely opened and closed without a hand being sandwiched between them.

  According to the bus board of the present invention, since the knob having a special shape is attached to the upper surface of the rotating member of the bus board, the user can ensure a part of his / her body weight by attaching his hand to the knob. It can be deposited on the bath board, and the side wall of the bathtub can be straddled in a standing state safely and easily.

  Hereinafter, a bus board according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments shown below, and various modifications can be made without departing from the technical idea of the present invention.

  FIG. 1 shows a bus board 1 according to an embodiment of the present invention attached to a bathtub 2. FIG. 2 shows a state in which the rotating member 4 of the bus board 1 shown in FIG. 1 is flipped up. FIG. 3 shows a bus board 1 ′ according to another embodiment of the present invention attached to the bathtub 2. 1 and 2, “front” means the lower left diagonal direction, and “rear” means the upper right diagonal direction. Therefore, “left” means the lower right diagonal direction, that is, the front side of the bathtub 2 (washing area side), and “right” means the upper left diagonal direction, that is, the rear side of the bathtub 2 (side wall side of the bathroom). means.

  As shown in FIGS. 1 and 2, the bus board 1 according to the present embodiment is disposed on the inner side of the plate-like support base 3 placed on the upper surface 21 of the bathtub side wall 20 and the support base 3. In addition, it is composed of a plate-like rotation member 4 that is rotatably attached to the support base 3 and a knob 5 that is attached to the upper surface of the rotation member 4.

  In addition, the material used for the bus board 1 is not particularly limited as long as it has the strength required for each part. However, since the bathroom is a severe and hot corrosive environment, it is resistant to corrosion. A high-weight and lightweight plastic material is used as a main material.

  The support base 3 forms a part of the stool portion of the bus board 1, functions to fix the bus board 1 to the side wall 20 of the bathtub 2, and rotatably support a rotating member 4 described later. To do. For this reason, if the support base material 3 can be mounted in the upper surface 21 of the bathtub side wall 20, what has plate shape, rod shape, or the shape which combined them can be used. However, in the present embodiment, in consideration of stability when the bath board 1 is installed on the bathtub side wall 20, avoidance of damage to the upper surface 21 of the bathtub side wall 20, convenience for the user, and the like, a plate-like support base material 3 is used.

  The support base material 3 is a plate-like left side base material 31 a placed on the upper surface of the left side wall 22 a of the bathtub 2 and a plate-like right side placed on the upper surface of the right side wall 22 b of the bathtub 2. It includes a side base material 31b and a plate-like rear side base material 31c placed on the upper surface of the rear side wall 22c of the bathtub 2, and is integrally formed so as to form a substantially U-shape in plan view as a whole. Has been. For this reason, since the support base material 3 which concerns on this embodiment can be arrange | positioned so that the shape of the upper surface 21 of the bathtub side wall 20 may be arrange | positioned, stability at the time of attaching to the bathtub 2 is high, and it has very high rigidity.
