Description

  The present invention relates to a handrail for a bathtub provided with a pressure plate and a pressure receiving plate that can swing freely following the shape of the side wall of the bathtub to be fixed to the side wall of the bathtub, and in particular, the pressure receiving plate and / or the pressure plate is a neck. The press receiving plate support is related to a handrail for a bathtub that is attached to a movable frame so as to swing freely and without rattling.

  Conventionally, a handrail for a bathtub that can be detachably attached to a side wall of the bathtub is provided so that an elderly person or the like can easily support the body when entering or leaving the bathtub. Since the handrail for the bathtub can be entrusted to the user's total weight by the user, it must be firmly attached to the side wall of the bathtub. For this reason, the handrail for bathtubs in recent years is equipped with the press plate and press receiving plate for fixing the handrail for bathtubs by generally pinching the side wall of a bathtub strongly from an inner side and an outer side.

  On the other hand, bathtubs in recent years tend to have a complicated shape with many curved surfaces as the functionality and design diversify. For this reason, recent handrails for bathtubs are disclosed in, for example, Japanese Patent Application Laid-Open No. 2005-224394 (Patent Document 1), Japanese Patent Application Laid-Open No. 2010-244661 (Patent Document 2), and Japanese Patent Application Laid-Open No. 2100-189069 (Patent Document 3). By attaching play to the mounting part of the pressing plate to the bolt shaft and the mounting part of the pressing receiving plate to the main body frame, the pressing plate and the pressing receiving plate can be swingably attached to the handrail for the bathtub. It is possible to follow the curved shape of the bathtub side wall.

  However, when a side wall of a curved bathtub is sandwiched by using a pressing plate having a play in the mounting portion and a pressure receiving plate, when the load is applied in a direction different from the direction in which the clamping force works, the pressing plate The connection point of the attachment portion or the connection point of the attachment portion of the pressure receiving plate may be displaced in the load direction by the amount of play in the attachment portion with the bolt shaft or the main body frame. At this time, if the mounting portion of the pressure plate and the pressure receiving plate is displaced to the side where the bathtub side wall is thin, the distance between the pressure plate and the pressure receiving plate is relatively increased with respect to the thickness of the bathtub side wall. Therefore, the clamping force by the pressing plate and the pressure receiving plate is weakened, and a gap is formed between the side wall of the bathtub and the pressing plate or the pressure receiving plate, so that the handrail for the bathtub becomes the side wall of the bathtub. There was a problem of leaving.

  On the other hand, for example, as described in Japanese Patent Application Laid-Open No. 2001-177872 (Patent Document 4), a handrail for a bathtub is fixed to the side wall of the bathtub without rattling through the pressing plate and the pressure receiving plate. By using high-precision angle adjustment connection means such as hinges and ball joints for the attachment part of the pressure plate and pressure receiving plate, the bathtub with the pressure plate and pressure receiving plate attached to the bolt shaft and main body frame without providing play Handrails have been developed.

  However, when a high-precision angle adjustment connecting means such as a hinge or a ball joint is used for the attachment portion of the pressing plate or the pressure receiving plate, when the pressing plate or the pressure receiving plate is pushed in at a relatively high feed rate, the high accuracy As a result of generating an excessive frictional force in the sliding portion of the angle adjusting connecting means, there has been a problem that the swing angle is fixed before the pressing plate or the pressing receiving plate follows the shape of the side wall of the bathtub. Therefore, in the case of a handrail for a bathtub using a highly accurate angle adjustment connecting means at the attachment part of the pressing plate or the pressing receiving plate, the side wall of the bathtub cannot be firmly and securely sandwiched, and the bathtub There was a problem of detaching from the side wall. Furthermore, the use of high-precision angle adjustment connecting means such as hinges and ball joints has a problem in that it greatly increases the manufacturing accuracy and manufacturing cost of the handrail for bathtubs.

  Therefore, the present invention provides a handrail for a bathtub that is fixed to the side wall of the bathtub by sandwiching the side wall of the bathtub with the press plate and the pressure receiving plate, so that the press plate and the pressure receiving plate can be easily formed into a curved shape of the bathtub side wall. It is possible to follow and firmly clamp the side wall of the bathtub, and after fixing the handrail for the bathtub to the side wall of the bathtub, the play of the mounting portion of the pressing plate or the pressure receiving plate or the side wall of the bathtub Insufficient follow-up (angle adjustment) of the pressing plate or the pressure receiving plate with respect to the shape may cause the holding force by the pressing plate and the pressure receiving plate to be unexpectedly weakened, or as a result, the handrail for the bathtub may be detached from the side wall of the bathtub. An object is to provide a handrail for a bathtub in which nothing is prevented.

  In the handrail for a bathtub fixed to the side wall of the bathtub by sandwiching the side wall of the bathtub with the pressing plate and the pressure receiving plate, the present inventors can easily form the pressing plate and the pressure receiving plate into the curved shape of the bathtub side wall, etc. A structure that can be followed, and a structure that does not loosen the clamping force due to play of the mounting portion of the pressing plate or the pressure receiving plate after the handrail for the bathtub is fixed to the side wall of the bathtub by the pressing plate and the pressure receiving plate As a result of repeated studies, the mounting portion of the pressure plate and / or the pressure receiving plate is swingable only in a predetermined direction without providing play and a first connecting portion that is free to swing with play. The present inventors have found that the above-described problems can be solved by combining with a free second connecting portion, and have completed the present invention.

  More specifically, the handrail for bathtub of the present invention is attached to the fixed frame disposed on the side wall of the bathtub, the bolt shaft attached to the vertical portion of the fixed frame via a nut, and the bolt shaft. , A pressing plate disposed opposite the side wall of the bathtub side wall, a movable frame slidably attached to the fixed frame, and swingable in the horizontal direction and / or vertical direction, and the vertical of the movable frame without rattling And a side wall of the bathtub opposite to the pressing plate, attached to the pressing receiving plate support so as to freely swing in the horizontal direction and / or the vertical direction and with play. And a pressure receiving plate disposed to face the side surface of the sheet.

  The handrail for bathtub of the present invention is roughly divided into a fixed frame and a movable frame, and the movable frame is slidably attached to the fixed frame. A bolt shaft is attached to the vertical portion of the fixed frame via a nut, and a pressure receiving plate is attached to the vertical portion of the movable frame via a pressure receiving plate support. The pressing plate is attached to the tip of the bolt shaft, and the bolt shaft or the nut can be rotated, and the bolt shaft screwed with the nut can be moved back and forth so that the pressing plate can be moved closer to or away from the side wall of the bathtub.

  In the handrail for bathtubs of the present invention, the press receiving plate is attached to a press receiving plate support described later so as to swing freely in the horizontal direction and / or the vertical direction and with play. In other words, the connecting portion between the pressure receiving plate and the pressure receiving plate support is allowed to have play due to play, and as a result, the angle of the pressure receiving plate is adjusted so that it can swing freely in all directions. The

  For this reason, the pressure receiving plate cannot swing the neck at a large angle with respect to the pressure receiving plate support, but there is almost no resistance such as friction when shaking the neck, so it fits perfectly with the side wall of the bathtub. The head can be shaken very easily and accurately for small angle changes. That is, the connecting portion between the pressure receiving plate and the pressure receiving plate support functions to accurately adjust the angle of the pressure receiving plate so that the pressure receiving plate is in close contact with the side wall of the bathtub.

  On the other hand, the pressure receiving plate support is attached to the vertical portion of the movable frame so as to be swingable in the horizontal direction and / or the vertical direction and without rattling. In other words, the pressure receiving plate support is an angle-adjustable connecting means such as a hinge or a ball joint, and the play of the pressure receiving plate support is substantially free from play, and thus is loose. The connecting portion can be moved smoothly without any problems. Further, the pressure receiving plate support need not be attached to the vertical portion of the movable frame so that the angle can be adjusted in all directions like the pressure receiving plate, and the angle can be adjusted in the horizontal direction and / or the vertical direction. It is preferably attached to the vertical part of the movable frame, and more preferably pivotally supported on the vertical part of the movable frame so as to be swingable only in the horizontal direction, such as a hinge.

  For this reason, the pressure receiving plate support has a larger resistance than the connecting portion between the pressure receiving plate and the pressure receiving plate support, but has a large angle with respect to the movable frame. The head can be swung very easily and quickly for large angle changes to roughly fit the side wall of the bathtub. That is, the pressure receiving plate support is inferior in accuracy to the connecting portion between the pressure receiving plate and the pressure receiving plate support, but the pressure receiving plate so that substantially the entire surface of the pressure receiving plate abuts the side wall of the bathtub easily. It functions to make large angle adjustments of the plate quickly and smoothly.

  As described above, in the handrail for bathtubs of the present invention, the pressure receiving plate has a first connecting portion that can accurately perform minute angle adjustment with a slight force, and a force larger than that of the first connecting portion. Although it is necessary, it has a feature that it is attached to the movable frame via a second connecting portion capable of instantaneously adjusting a large angle, that is, a pressure receiving plate support.

  For this reason, when the pressure receiving plate is pressed against the side wall of the bathtub, first, a large angle adjustment of the pressure receiving plate is performed by the pressure receiving plate support so that substantially the entire surface of the pressure receiving plate simply comes into contact with the side wall of the bathtub. It is done quickly and smoothly. Next, the pressure receiving plate is closely attached to the side wall of the bathtub by the connecting portion between the pressure receiving plate and the pressure receiving plate support substantially simultaneously with the large angle adjustment by the pressure receiving plate support. Thus, the fine angle adjustment of the pressure receiving plate is performed with high accuracy.

  For this reason, in the handrail for bathtubs according to the present invention, the angle of the press receiving plate is easily adjusted so as to be in close contact with the curved shape of the bathtub side wall, so that the side wall of the bathtub can be firmly and securely sandwiched. In addition, once the bathtub handrail is fixed to the side wall of the bathtub, the connecting portion between the pressure receiving plate and the pressure receiving plate support is closely attached so as not to be loose due to the synergistic effect with the pressure receiving plate support. Therefore, the holding force by the pressure receiving plate and the pressure plate is caused by the play provided at the connecting portion between the pressure receiving plate and the pressure receiving plate support or the angle adjustment (following) of the pressure receiving plate with respect to the side wall of the bathtub. It is prevented that the handrail for bathtub is detached from the side wall of the bathtub unexpectedly.

  In the handrail for bathtubs of the present invention, the fulcrum of swinging of the pressure receiving plate support can be arranged in the pressure receiving surface of the pressure receiving plate.

  Here, the swinging fulcrum is, for example, a shaft part that is pivotally connected so that the angle can be adjusted with respect to each other if the swinging function of the pressure receiving plate support is realized by a hinge structure or the like. For example, if the swing function of the pressure receiving plate support is realized by a ball joint structure or the like, it means the center of the ball shaft and the bearing portion that are rotatably connected to each other so that the angle can be adjusted. Thus, in the pressure receiving plate support, it means a connection point that is rotatably connected to each other so that the angle can be adjusted.

  Further, in this specification, the inside of the pressure receiving surface of the pressure receiving plate means not only the pressure receiving surface of the pressure receiving plate, but also, for example, a plate-like member having a flat pressure receiving plate and a sheet-like non-slip rubber. In such a case, the surface is parallel to the pressure receiving surface of the pressure receiving plate, and is a surface obtained by cutting the volume space formed by the flat plate-like member and the rubber in parallel with the pressure receiving surface. It is used including. For this reason, disposing within the pressure receiving surface of the pressure receiving plate is not only disposed on the pressure receiving surface of the pressure receiving plate, but also a surface parallel to the pressure receiving surface of the pressure receiving plate and flat. The meaning which arrange | positions the volume space formed by a plate-shaped member and a rubber on the surface cut out in parallel with the press receiving surface is also included. Of course, when the pressure receiving plate is a pressing plate, the arrangement within the pressing surface of the pressing plate is not only a positioning on the pressing surface of the pressing plate, but also a surface parallel to the pressing surface of the pressing plate. Moreover, the meaning which arrange | positions the volume space formed by a flat plate-shaped member and rubber on the surface cut out in parallel with the pressing surface is also included.

  In a handrail for a bathtub that is fixed to the side wall of the bathtub by the holding force of the pressure receiving plate and the pressure plate, the force transmitted from the movable frame to the pressure receiving plate is usually via the swinging fulcrum of the pressure receiving plate support. Communicated. For this reason, when the fulcrum of swinging of the pressure receiving plate support is arranged within the pressure receiving surface of the pressure receiving plate, the force vector transmitted through the fulcrum of swinging of the pressure receiving plate support is No matter which direction is directed with respect to the pressure receiving plate support, it will pass through a predetermined fixed position on the pressure receiving surface, that is, a substantially swinging fulcrum (see FIG. 14a). The pressure receiving plate can always hold the side wall of the bathtub with a stable pressing force regardless of the swing angle.

  On the other hand, in the handrail for bathtubs according to the present invention, the fulcrum of swinging of the pressure receiving plate support can be arranged away from the pressure receiving surface of the pressure receiving plate.

  The inside of the pressure receiving surface of the pressure receiving plate not only means the pressure receiving surface of the pressure receiving plate, but also, for example, when the pressure receiving plate is made of a flat plate-like member and a sheet-like non-slip rubber Uses a surface parallel to the pressure receiving surface of the pressure receiving plate, including a surface obtained by cutting the volume space formed by the flat plate member and the rubber in parallel with the pressure receiving surface. . For this reason, disposing away from the pressure receiving surface of the pressure receiving plate is not only arranged away from the pressure receiving surface of the pressure receiving plate, but also a surface parallel to the pressure receiving surface of the pressure receiving plate. Moreover, the meaning which arrange | positions the volume space formed by a flat plate-shaped member and rubber away from the surface cut off in parallel with the press receiving surface is also included. Of course, when the pressure receiving plate is a pressing plate, disposing it away from the pressing surface of the pressing plate means not only disposing it away from the pressing surface of the pressing plate, but parallel to the pressing surface of the pressing plate. The meaning of disposing a volume space formed by a flat plate-like member and rubber away from a surface cut parallel to the pressing surface is also included.

  In a handrail for a bathtub that is fixed to the side wall of the bathtub by the holding force of the pressure receiving plate and the pressure plate, the force transmitted from the movable frame to the pressure receiving plate is the fulcrum of the swinging of the pressure receiving plate support as described above. Is transmitted through. For this reason, when the fulcrum of swinging of the pressure receiving plate support is arranged within the pressure receiving surface of the pressure receiving plate, the force vector transmitted through the fulcrum of swinging of the pressure receiving plate support is Regardless of the swing angle, it is impossible to pass a predetermined fixed position on the pressure receiving surface, and it passes an unspecified position on the pressure receiving surface according to the swing angle of the pressure receiving plate. Therefore (see FIG. 14b), even on the same pressure receiving surface, it is possible to generate a portion where the pressing force is strong and a portion where the pressing force is weak. Such a distribution of the pressing force is strong because the pressing force per unit area generated in the pressure receiving plate can be made uniform when the handrail for the bathtub is attached to the side wall of the bathtub where the thickness is not constant. It is advantageous for preventing breakage of the bathtub side wall while obtaining clamping force.

  In the handrail for bathtubs of the present invention, the pressure receiving plate supported so as to be swingable by the pressure receiving plate support does not need to be a single flat pressure receiving plate, but from a plurality of pressure receiving plates. It may be configured. In this case, it is preferable that the plurality of press receiving plates are connected to each other by a press receiving plate support or a dedicated connecting tool attached to the press receiving plate support so that it can be supported by one movable frame. Further, when a plurality of press receiving plates are attached to the press receiving plate support via a dedicated connector, each press receiving plate can swing freely in the horizontal direction and / or the vertical direction and play. It must be attached to a dedicated connector.

  When the pressure receiving plate is divided into a plurality of pressure receiving plates, the swing angle can be finely adjusted in accordance with the shape of the bathtub side wall that contacts each pressure receiving plate. It is convenient when it is intended to exert a strong clamping force by being in close contact with each other. However, the connecting portion between the pressure receiving plate and the pressure receiving plate support or the connecting portion between the pressure receiving plate and the dedicated connecting device cannot swing the neck with a large angle like the pressure receiving plate support. The number of the pressure receiving plates attached to the pressure receiving plate support or the dedicated connector is preferably 2 to 3.

  Further, when the pressure receiving plate is divided into a plurality of pressure receiving plates, among the plurality of pressure receiving plates, at least two of the pressure receiving plates can be a pressure receiving plate having pressure receiving surfaces having different areas.

  If the handrail for bathtub is attached to the bathtub side wall where the thickness is not constant, there may be a difference in pressing force for each pressure receiving plate, so by setting the pressure receiving surfaces of at least two pressure receiving plates to different areas, There is an advantage that the pressing force per unit area generated in the pressure receiving plate can be made uniform.

  In the handrail for bathtubs according to the present invention, the pressure receiving plate needs a force greater than the first connecting portion and the first connecting portion capable of accurately performing fine angle adjustment with a slight force. However, at the same time as attaching to the movable frame via the second connecting part, that is, the pressure receiving plate support, capable of performing large angle adjustment instantaneously, the angle adjustment with a slight force is performed with high precision. The first connecting part that can be performed and the second connecting part that requires a larger force than the first connecting part but can perform a large angle adjustment instantaneously, that is, pressing as a pressing plate support The above-described excellent effects of the present invention can also be achieved by attaching to the tip of the bolt shaft via the backing plate support.

  A handrail for a bathtub according to another embodiment of the present invention includes a fixed frame disposed on a side wall of the bathtub, a bolt shaft attached to a vertical portion of the fixed frame via a nut, and a neck in a horizontal direction and / or a vertical direction. A pressing plate support attached to the bolt shaft so as to be swingable and without rattling, and attached to the pressing plate support so as to freely swing in the horizontal direction and / or the vertical direction and with play. A pressure plate disposed opposite to the side surface of the side wall of the tub, a movable frame slidably attached to the fixed frame, and attached to a vertical portion of the movable frame, on the side surface of the side wall of the bathtub opposite to the pressure plate And a pressure receiving plate disposed to face each other.

  The bathtub handrail according to the present invention in this form is roughly divided into a fixed frame and a movable frame, and the movable frame is slidably attached to the fixed frame. A bolt shaft is attached to the vertical portion of the fixed frame via a nut, and a pressure receiving plate is attached to the vertical portion of the movable frame. The pressing plate is attached to the tip of the bolt shaft via a pressing plate support, and the bolt shaft or the nut is rotated, and the bolt shaft screwed to the nut is screwed back and forth, so that the pressing plate is attached to the side wall of the bathtub. Proximity and separation can be achieved.

  In the handrail for bathtubs of the present invention, the pressing plate is attached to a pressing plate support described later so as to swing freely in the horizontal direction and / or the vertical direction and with play. That is, the connecting portion between the pressing plate and the pressing plate support is allowed to have a play due to the provision of play, and as a result, the angle of the pressing plate is adjusted so as to freely swing in all directions.

  For this reason, the pressing plate cannot swing the neck at a large angle with respect to the pressing plate support, but has almost no resistance such as friction when shaking the neck, so it fits snugly with the side wall of the bathtub. The head can be shaken very easily and accurately for small angle changes. That is, the connecting portion between the pressing plate and the pressing plate support functions in order to precisely adjust the angle of the pressing plate so that the pressing plate is in close contact with the side wall of the bathtub.

  On the other hand, the pressing plate support is swingably mounted in the horizontal direction and / or the vertical direction and attached to the bolt shaft without rattling. In other words, the pressing plate support is an angle-adjustable connecting means such as a hinge or a ball joint, and since there is substantially no play at the connecting portion of the pressing plate support, there is no backlash. The connecting portion can be moved smoothly. Further, the pressing plate support need not be attached to the bolt shaft so that the angle can be adjusted in all directions like the pressing plate, and is attached to the bolt shaft so that the angle can be adjusted in the horizontal direction and / or the vertical direction. For example, like a hinge, it is more preferable that the shaft is supported on the bolt shaft so as to be swingable only in the horizontal direction.

  For this reason, the pressure plate support tool has a greater resistance to friction when swaying the neck than the connecting part between the pressure plate and the pressure plate support tool. Since it can be shaken, it is possible to shake the head very easily and quickly for a large angle change to roughly fit the side wall of the bathtub. That is, the pressure plate support is less accurate than the connecting portion between the pressure plate and the pressure plate support, but the angle of the pressure plate is adjusted so that the substantially entire surface of the pressure plate can easily come into contact with the side wall of the bathtub. It works to make it quick and smooth.

  As described above, in the handrail for bathtubs according to another embodiment of the present invention, the pressing plate is more accurate than the first connecting portion and the first connecting portion that can perform fine angle adjustment with a slight force with high accuracy. Although it requires a large force, it has a feature that it is attached to the bolt shaft via a second connecting portion capable of instantaneously adjusting a large angle, that is, a pressing plate support.

  For this reason, when the pressing plate is pressed against the side wall of the bathtub, first, a large angle adjustment of the pressing plate is quickly and smoothly performed by the pressing plate support so that the substantially entire surface of the pressing plate comes into contact with the side wall of the bathtub easily. Done. Next, the pressing plate is adjusted so that the pressing plate is in close contact with the side wall of the bathtub even at the same time when the large angle adjustment is performed by the pressing plate support. Minute angle adjustment is performed with high accuracy.

  For this reason, in the handrail for bathtubs of the present invention, the angle of the pressing plate is easily adjusted so as to be in close contact with the curved shape of the bathtub side wall, etc., so that the side wall of the bathtub can be firmly and securely held. Also, once the bathtub handrail is fixed to the side wall of the bathtub, the connecting portion of the pressing plate and the pressing plate support is brought into close contact with the pressing plate support so as not to cause backlash. The clamping force by the pressing plate and the pressing receiving plate is suddenly weakened due to the play provided at the connecting portion between the pressing plate and the pressing plate support, or the angle adjustment (following) of the pressing plate with respect to the side wall of the bathtub, or As a result, it is possible to prevent the handrail for the bathtub from being detached from the side wall of the bathtub.

  In the handrail for bathtubs of the other form of this invention, the fulcrum of the swing of a press plate support tool can be arrange | positioned in the press surface of a press plate.

  Here, the swinging fulcrum means, for example, a shaft part that is pivotally connected so that the angle can be adjusted with respect to each other if the swinging function of the pressing plate support is realized by a hinge structure or the like. For example, if the swinging function of the pressing plate support is realized by a ball joint structure or the like, it means the center of the ball shaft and the bearing portion that are rotatably connected to each other so that the angle can be adjusted. Furthermore, in the pressing plate support, it means a connecting point that is rotatably connected to each other so that the angle can be adjusted.

  Further, in the present specification, the inside of the pressing surface of the pressing plate not only means the surface portion of the pressing surface, but the pressing plate is made of a flat plate-like material and a sheet-like non-slip rubber, for example. In such a case, the flat plate-shaped material and the rubber are used so as to include the plane parallel to the surface portion of the pressing surface. For this reason, arranging within the pressing surface of the pressing plate not only arranges so as to be flush with the surface portion of the pressing surface, but also traverses within the flat plate-like material and rubber constituting the pressing plate. It also means that it is arranged so as to be flush with a surface parallel to the surface portion of the pressing surface.

  In a bathtub handrail that is fixed to the side wall of the bathtub by the clamping force of the pressing plate and the pressing receiving plate, the force transmitted from the movable frame to the pressing plate is usually transmitted through the swinging fulcrum of the pressing plate support. The For this reason, when the fulcrum of the swing of the pressing plate support is disposed within the pressing surface of the pressing plate, the force vector transmitted through the fulcrum of the swing of the pressing plate support is No matter which direction it is directed, it passes through a predetermined fixed position on the pressing surface, that is, a substantially swinging fulcrum (see FIG. 14a). Regardless of the swing angle, the side wall of the bathtub can always be held with a stable pressing force.

  On the other hand, in the handrail for bathtubs of the other form of this invention, the fulcrum of the swing of a press plate support tool can also be spaced apart from the press surface of a press plate.

  The pressing surface of the pressing plate means not only the surface portion of the pressing surface, but also, for example, when the pressing plate is made of a flat plate material and a sheet-like non-slip rubber, the flat plate shape It also means including a surface that traverses the material and the rubber and is parallel to the surface portion of the pressing surface. For this reason, disposing away from the pressing surface of the pressing plate not only disposes away from the surface portion of the pressing surface, but also traverses the flat plate-like material and rubber constituting the pressing plate and It is also included that they are arranged away from a plane parallel to the surface portion of the pressing surface.

  In the handrail for bathtubs that is fixed to the side wall of the bathtub by the clamping force of the pressing plate and the pressing receiving plate, the force transmitted from the movable frame to the pressing plate is via the fulcrum of the swinging of the pressing plate support as described above. Communicated. For this reason, when the fulcrum of the swing of the pressing plate support is arranged away from the pressing receiving surface of the pressing plate, the force vector transmitted through the fulcrum of the swing of the pressing plate support is the neck of the pressing plate. Since it becomes impossible to pass a predetermined fixed position on the pressing surface regardless of the swing angle, it passes an unspecified position on the pressing surface according to the swing angle of the pressing plate (see FIG. 14b). ) Even on the same pressing surface, it is possible to generate a portion where the pressing force is strong and a portion where the pressing force is weak. Such a distribution of the pressing force can make the pressing force per unit area uniform in the pressing plate when the handrail for the bathtub is attached to the side wall of the bathtub where the thickness is not constant. It is advantageous for preventing breakage of the bathtub side wall while obtaining force.

  In the handrail for bathtubs according to another embodiment of the present invention, the pressing plate supported to be swingable by the pressing plate support does not need to be a single continuous pressing plate, but from a plurality of pressing plates. It may be configured. In this case, it is preferable that the plurality of pressing plates are connected to each other by a pressing plate support or a dedicated connector attached to the pressing plate support so that the pressing plates can be supported by one movable frame. In addition, when a plurality of pressing plates are attached to the pressing plate support via a dedicated connector, each pressing plate is swingable in the horizontal direction and / or vertical direction and has a play. Must be attached to the connector.

  When the pressing plate is divided into a plurality of pressing plates, the swing angle can be finely adjusted according to the shape of the bathtub side wall that contacts each pressing plate, so the pressing plate is brought into close contact with the side wall of the bathtub. This is convenient when trying to exert a strong clamping force. However, the connecting part between the pressing plate and the pressing plate support or the connecting part between the pressing plate and the dedicated connecting tool cannot swing the neck with a large angle like the pressing plate support. It is preferable that the number of the plurality of pressing plates attached to the tool or the dedicated connector is two to three.

  Moreover, when dividing | segmenting a press plate into a some press plate, at least 2 press plate can be made into the press plate which has a press surface of a mutually different area among some press plates.

  If the handrail for bathtub is attached to the bathtub side wall where the thickness is not constant, there may be a difference in pressing force for each pressing plate, so by setting the pressing surfaces of at least two pressing plates to areas different from each other, There is an advantage that the generated pressing force per unit area can be made uniform.

  In the handrail for bathtubs according to another embodiment of the present invention, the pressing plate is capable of accurately adjusting a minute angle with a slight force and a force larger than that of the first connecting portion. However, at the same time as attaching to the bolt shaft via the pressing plate support, the pressure receiving plate can be adjusted minutely with a slight force. The first connecting part that can accurately perform the operation and the second connecting part that requires a larger force than the first connecting part, but can perform a large angle adjustment instantaneously, that is, a pressure receiving plate support The above-described excellent effects of the present invention can also be achieved by attaching to the movable frame via a pressing plate support as a tool.

  Furthermore, the handrail for bathtubs of the present invention includes a first engaging portion that includes a concave portion or a convex portion and is formed on the front surface or the back surface of the movable frame, and a first engaging portion that includes the convex portion or the concave portion. A second engaging portion arranged at an opposing position, an operating portion arranged on the surface side of the movable frame and operated by a user, and a connecting portion connecting the second engaging portion and the operating portion And urging means for urging the second engagement portion to engage the first engagement portion, and the second engagement portion is urged by operating the operation portion. And a slide locking / releasing means attached to the fixed frame configured to be separated from the first engaging portion against the urging force by the first engaging portion and the second engaging portion. The contact surface with the engaging portion is a surface orthogonal to the front or back surface of the movable frame and is not parallel to the sliding direction of the movable frame. It may be configured to include that surface.

  The first engaging portion includes a concave portion or a convex portion, and is formed on the front surface or the back surface of the movable frame. The slide locking / releasing means includes a second engaging portion, an operation portion, a connecting portion, and an urging means, and the second engaging portion includes a convex portion or a concave portion, It arrange | positions in the position facing the engaging part. The operation unit is arranged on the surface side of the movable frame and is operated by the user. The connecting portion connects the second engaging portion and the operation portion. The urging means urges the second engagement portion to engage the first engagement portion. The slide locking / releasing means is configured such that the second engaging part is separated from the first engaging part against the urging by the urging means by operating the operating part.

  The contact surface between the first engagement portion and the second engagement portion is a surface orthogonal to the front surface or the back surface of the movable frame and includes a surface that is not parallel to the sliding direction of the movable frame.

  Hereinafter, the surface of the movable frame refers to a surface that is exposed to the outside when the movable frame and the fixed frame are assembled and can be generally contacted by the user. The back surface of the movable frame refers to a surface formed at a position opposite to the surface of the movable frame in the thickness direction of the movable frame, and is generally not exposed to the outside when the movable frame and the fixed frame are assembled. This is the surface that the user does not touch. Further, the movement of the movable frame in a direction approaching the bathtub wall surface is sometimes referred to as advancement of the movable frame, and the movement of the movable frame in a direction away from the bathtub wall surface is sometimes referred to as retraction of the movable frame.

  As described above, the first engaging portion including the concave portion or the convex portion is formed on the front surface or the back surface of the movable frame, and the first engaging portion is a slide locking / releasing means attached to the fixed frame. It arrange | positions facing the 2nd engaging part.

  A convex part or a concave part is formed in the second engaging part, and the second engaging part is urged to be engaged with the first engaging part by the urging means. For this reason, when the 1st engaging part is formed in the surface of a movable frame, a user operates the operation part arrange | positioned at the surface side of a movable frame, and resists urging | biasing by a biasing means. Then, by pulling up the slide locking / releasing means, or when the first engagement portion is formed on the back surface of the movable frame, the user operates the operation portion arranged on the front surface side of the movable frame. Then, the second engaging portion is separated from the first engaging portion by pushing the slide locking / releasing means against the urging by the urging means.

  The second engaging portion of the slide locking / releasing means is located on the surface side of the movable frame when the first engaging portion is formed on the surface of the movable frame, or the first engaging portion is the movable frame. When it is formed on the back surface of the movable frame, it is disposed between the back surface of the movable frame and the fixed frame. Since the second engaging portion is connected to the operation portion arranged on the surface side of the movable frame by the connecting portion, the user operates the operation portion from the surface side of the movable frame, so that the surface side of the movable frame Alternatively, the second engaging portion arranged on the back side can be separated from the first engaging portion. Thus, in the handrail for bathtubs of this invention, the 1st engaging part and 2nd engaging part which were formed in the surface or back surface of a movable frame operate without a user touching a hand directly. be able to. In particular, when the first engagement portion is provided on the back surface of the movable frame, the first engagement portion and the second engagement portion are covered by the movable frame, so that the user cannot touch the hand directly. It is impossible and safe.

  Further, the contact surface between the first engagement portion and the second engagement portion is a surface orthogonal to the front or back surface of the movable frame and includes a surface that is not parallel to the sliding direction of the movable frame. The second engaging portion disposed on the front side or the back side of the movable frame by the user operating the operating portion to lift or push the slide locking / releasing means against the biasing by the biasing means Unless they are separated from the first engaging portion, the first engaging portion and the second engaging portion come into contact in a plane non-parallel to the sliding direction of the movable frame, thereby preventing the movable frame from sliding. In this way, it is possible to prevent the movable frame from being accidentally slid.

  The user operates the operation unit to raise or push the slide locking / release means against the urging force by the urging means, both when moving the movable frame closer to the bathtub wall surface and away from the bathtub wall surface. Thus, the movable frame can be slid. Thus, since the movable frame can be slid in any direction by the same operation, the operation is easy. In addition, in order to release the slide lock of the movable frame, the second engagement portion may be separated from the first engagement portion against the biasing force by the biasing means. The operation of the operation units connected by the units is not limited to a pulling operation or a pushing operation.

  The handrail for bathtubs of the present invention includes a surface that contacts the second engaging portion at the concave portion or convex portion of the first engaging portion, and the first engagement at the convex portion or concave portion of the second engaging portion. The surface in contact with the part preferably has a cylindrical peripheral surface shape. Therefore, in the handrail for bathtubs of the present invention, for example, the second engaging portion includes a columnar convex portion, and the first engaging portion is a side periphery of a cylinder that receives the convex portion of the second engaging portion. A surface-shaped recess may be included.

  The first engagement is such that the second engaging portion is a cylindrical convex portion, and the first engaging portion is a cylindrical side circumferential concave portion that receives the convex portion of the second engaging portion. The surface that contacts the second engaging portion in the concave portion or the convex portion of the portion and the surface that contacts the first engaging portion in the convex portion or the concave portion of the second engaging portion have a cylindrical side peripheral surface shape. Then, even if the fitting accuracy between the first engagement portion and the second engagement portion is somewhat rough, the first engagement portion and the second engagement portion are not parallel to the sliding direction of the movable frame. It is possible to reliably contact within a smooth surface and reliably prevent sliding of the movable frame. In the above case, since the contact surface between the first engagement portion and the second engagement portion is formed by a curved surface, local wear of the first engagement portion and the second engagement portion. Etc. are suppressed, and there is also a benefit that the durability of the product is improved.

  In the handrail for bathtubs according to the present invention, it is preferable that the fixed frame includes a second concave portion having a cylindrical side peripheral surface that receives the convex portion of the second engaging portion.

  When the second concave portion having a cylindrical side peripheral surface shape for receiving the columnar convex portion of the second engaging portion is formed on the fixed frame, the first engaging portion is formed on the surface of the movable frame. The second engaging portion having the movable frame inserted therethrough is inserted into the second recessed portion of the fixed frame, so that the convex portion and the connecting portion of the second engaging portion are Since two points can be supported by the second concave portion of the fixed frame, sliding of the movable frame can be firmly prevented. Further, when the first engaging portion is formed on the back surface of the movable frame, when the slide locking / releasing means is released, the convex portion of the second engaging portion is the second of the fixed frame. Since it is accommodated in the concave portion, it is not necessary to provide an extra space for retracting the convex portion of the second engagement portion on the fixed frame, and the mounting structure of the fixed frame and the movable frame is thinned as a whole. be able to.

  In the handrail for bathtubs according to the present invention, as a configuration in which the movable frame is slidably attached to the fixed frame, the fixed frame extends in a substantially horizontal direction with a vertical portion extending in a substantially vertical direction and disposed substantially parallel to the side wall of the bathtub. A horizontal portion, and a plurality of reinforcing ribs are formed between the horizontal portion and the vertical portion of the fixed frame, and the reinforcing ribs extend in a direction substantially orthogonal to the vertical portion of the fixed frame at the horizontal portion of the fixed frame. The movable frame includes a vertical portion extending in a substantially vertical direction and disposed substantially parallel to the side wall of the bathtub, and a horizontal portion extending in a substantially horizontal direction, and the horizontal portion of the movable frame is formed of a plurality of reinforcing ribs. You may arrange | position so that it may slidably contact | connect between them, and you may screw on a fixed frame.

  As a result, the handrail for bathtubs of the present invention having a configuration in which the movable frame is slidably attached to the fixed frame can increase durability and increase attachment strength without greatly increasing the weight.

  Furthermore, as another configuration for slidably attaching the movable frame to the fixed frame, the fixed frame includes a vertical portion extending in a substantially vertical direction and disposed substantially parallel to the side wall of the bathtub, and a horizontal portion extending in a substantially horizontal direction. The reinforcing rib is formed across the horizontal portion and the vertical portion of the fixed frame, the reinforcing rib is extended in a direction substantially perpendicular to the vertical portion of the fixed frame at the horizontal portion of the fixed frame, and the movable frame is It is composed of a vertical part extending in a substantially vertical direction and arranged substantially parallel to the side wall of the bathtub, and a horizontal part extending in a substantially horizontal direction. A movable frame is formed so as to be opposed to each other with the reinforcing rib interposed therebetween and extending in a direction substantially orthogonal to the vertical portion of the movable frame. In a state of being attached to the fixed frame, the movable frame is arranged so that the first leg and the second leg are in sliding contact with the reinforcement rib with the reinforcement rib interposed therebetween, and the horizontal portion of the movable frame is screwed. For example, it can be fixed to the reinforcing rib of the fixed frame.

  As a result, in the handrail for bathtub of the present invention having a configuration in which the movable frame is slidably attached to the fixed frame, the fixed frame and the movable frame are each provided with durability and reinforcement by the reinforcing rib and the first and second legs. The mounting strength is enhanced, and it is easy to fix according to the thickness of the bathtub side wall, and the mounting work to the bathtub side wall and the removing work from the bathtub side wall can be performed safely and easily. Can do.

  According to the present invention, the pressure receiving plate and / or the pressure plate requires a first connecting portion capable of accurately performing minute angle adjustment with a slight force and a force larger than that of the first connecting portion. However, since it is attached to the movable frame through the second connecting portion, that is, the pressure receiving plate support, and / or the bolt shaft through the pressure plate support, which can instantaneously perform a large angle adjustment, When the pressure receiving plate and / or the pressing plate is pressed against the side wall of the bathtub, the pressure receiving plate and / or the pressing plate support first causes the substantially entire surface of the pressure receiving plate and / or the pressing plate to reach the side wall of the bathtub. A large angle adjustment of the pressure receiving plate and / or the pressure plate is performed quickly and smoothly so as to make contact easily. Next, the pressure receiving plate and / or the pressing plate is connected to the connecting portion between the pressure receiving plate and the pressure receiving plate support substantially simultaneously with the large angle adjustment performed by the pressure receiving plate support and / or the pressing plate support. Even with the connecting portion between the pressing plate and the pressing plate support, fine adjustment of the angle of the pressing plate and / or the pressing plate is performed with high accuracy so that the pressing plate and / or the pressing plate is in close contact with the side wall of the bathtub. Is called.

  For this reason, in the handrail for bathtubs according to the present invention, the angle of the pressure receiving plate and / or the pressure plate is easily adjusted so as to be in close contact with the curved shape of the bathtub side wall, so that the side wall of the bathtub is firmly and securely sandwiched. can do. Further, once the bathtub handrail is fixed to the side wall of the bathtub, the connecting portion between the pressure receiving plate and the pressure receiving plate support and / or the connecting portion between the pressing plate and the pressing plate support is supported by the pressure receiving plate. Because of the synergistic effect with the tool and / or the pressing plate support, it is brought into close contact with the ratchet, so that the connecting portion between the pressing plate and the pressing plate support and / or the pressing plate and the pressing plate support Due to the play provided in the connecting portion and the lack of angle adjustment (following) of the pressure receiving plate and / or the pressure plate with respect to the side wall of the bathtub, the clamping force by the pressure receiving plate and the pressure plate is unexpectedly weakened, or as a result It is prevented that the handrail is detached from the side wall of the bathtub.

  The whole figure is shown by FIG. 1 as a common structure of the handrail 1 for bathtubs which concerns on one Embodiment of this invention. For this reason, the handrail 1 for bathtubs shown by FIG. 1 shows the basic composition of the handrails 1a, 1b, 1c, 1d for bathtubs which concern on 1st-4th embodiment mentioned later. The number of plates, the mounting structure of the pressure receiving plate, the pressure receiving plate support, and the movable frame, the number of the pressing plates, the mounting structure of the pressing plate, the pressing plate support, and the bolt shaft, etc. are described in the first to fourth embodiments. It differs depending on the handrails 1a, 1b, 1c, 1d for bathtubs.

  As shown in FIG. 1, a handrail 1 for a bathtub according to an embodiment of the present invention mainly includes a main body 10 and an upper grip 11 supported by the main body 10. The main body 10 is covered with a top cover 12. On the upper surface of the upper cover 12, an operation portion 60 of a slide locking / releasing means described later is exposed. The main body 10 includes a fixed frame 2, a movable frame 3, and a slide locking / releasing means. A pressing plate 4 and a handle knob 70 are attached to the fixed frame 2. A press receiving plate 5 and a side grip 13 are attached to the movable frame 3. The pressure plate 4 and the pressure receiving plate 5 are respectively disposed so as to face the side wall of the bathtub when the bathtub handrail 1 is installed on the side wall of the bathtub. The upper grip 11 is fixed to the column 14. The upper grip 11 is supported by the main body 10 by accommodating a part of the column 14 in the main body 10.

  The fixed frame 2 is formed in an L shape and includes a horizontal portion 20 and a vertical portion 21. With the main body 10 attached to the side wall of the bathtub, the horizontal portion 20 extends in the horizontal plane, and the vertical portion 21 extends downward from the end of the horizontal portion 20 and extends in the vertical plane. The side cover 15 is attached so as to cover the outer surface of the vertical portion 21 of the fixed frame 2. The side cover 15 is formed with a through hole for accommodating the upper grip 11. The pressing plate 4 is attached so as to protrude from the inner surface of the vertical portion 21 of the fixed frame 2. The handle knob 70 is attached to the side cover 15. In the case of the handrail 1a for a bathtub according to the first embodiment shown in FIG. 2 described later, the handle knob 70 and the pressing plate 4a are connected by a bolt shaft 7a, a nut 71a, and a torque transmission mechanism 8. In the case of the handrail 1b for a bathtub according to the second embodiment shown in FIG. 9, the handle knob 70 and the pressing plate 4b are connected by the pressing plate support 40b, the bolt shaft 7b, the nut 71b, and the torque transmission mechanism 8. ing. By turning the handle knob 70, rotational force is transmitted from the handle knob 70 to the nuts 71a and 71b, and the bolt shafts 7a and 7b screwed with the nuts 71a and 71b are screwed back and forth, whereby the fixed frames 2a and 2b. The pressing plates 4a and 4b are moved forward and backward along a direction orthogonal to the surfaces of the vertical portions 21a and 21b.

[First Embodiment]
FIG. 2 shows a cross-sectional view of the handrail 1a for the bathtub according to the first embodiment as seen from the direction of the line XX shown in FIG. 1, and FIG. 3 shows the hand for the bathtub according to the first embodiment. A cross-sectional view of the slide 1a viewed from the direction of the YY line shown in FIG. 1 is shown. 4 is an exploded perspective view showing components of the fixed frame 2a, the bolt shaft 7a, the torque transmission mechanism 8, and the pressure receiving plate 4a of the handrail 1a for the bathtub according to the first embodiment. These are the exploded perspective views which show the structural member of the movable frame 3a of the handrail 1a for bathtubs of 1st Embodiment, the press receiving plate support tool 50a, and the press receiving plate 5a.

  As shown in FIGS. 2 and 3, the handrail 1a for the bathtub according to the first embodiment is attached to the fixed frame 2a disposed on the side wall of the bathtub and the vertical portion 21a of the fixed frame 2a via the nut 71a. A bolt shaft 7a, a pressing plate 4a that is attached to the side wall of the bathtub side wall, a movable frame 3a that is slidably attached to the fixed frame 2a, a horizontal direction and / or Or, it is possible to swing freely in the vertical direction and with the pressure receiving plate support 50a attached to the vertical portion 31a of the movable frame 3a without rattling, and to swing freely in the horizontal direction and / or the vertical direction, and to play. It is attached to the pressure receiving plate support 50a and has a pressure receiving plate 5a disposed opposite to the side surface of the side wall of the bathtub opposite to the pressing plate 4a. ing. Unlike the pressure receiving plate 5 of the handrail 1 for a bathtub shown in FIG. 1, the pressure receiving plate 5a is divided into a pair of left and right, and a pressure receiving plate support is provided via a connecting plate (not shown). It is attached to 50a.

  As shown in FIG. 4, the fixed frame 2 a is formed in an L shape and includes a horizontal portion 20 a and a vertical portion 21 a. With the main body 10a attached to the side wall of the bathtub, the horizontal portion 20a extends in the horizontal plane, and the vertical portion 21a extends downward from the end portion of the horizontal portion 20a and extends in the vertical plane. A plurality of large reinforcing ribs 22a for reinforcing the fixed frame 2a and a plurality of small sizes for guiding the movable frame 3a in a slidable manner over the horizontal portion 20a and the vertical portion 21a of the fixed frame 2a. Reinforcing ribs 23a are formed, and both of the reinforcing ribs 22a and 23a extend in a direction substantially orthogonal to the vertical portion 21a of the fixed frame 2a in the horizontal portion 20a of the fixed frame 2a.

  The handle knob 70 and the pressing plate 4a are connected by a bolt shaft 7a, a nut 71a, and a torque transmission mechanism 8. The torque transmission mechanism 8 includes a substantially circular torque transmission surface orthogonal to the rotation axis of the bolt shaft 7a, and a first annular member 80 that synchronizes with the rotation of the handle knob 70 by a fitting structure, and torque A second annular member 81 which is provided with a substantially circular torque transmission surface which is in contact with the transmission surface and which is orthogonal to the rotation axis of the nut 71a, and which is attached to the nut 71a by a fitting structure; A coil spring 82 that biases the torque transmission surface of one annular member 80 toward the torque transmission surface of the second annular member 81 is provided. The coil spring 82 is fixed by a stopper 83 attached to the end of the nut 71a with a screw.

  When the torque transmitted to the first annular member 80 and the torque transmission surface of the second annular member 81 are less than a predetermined value, the torque transmission surface and the torque transmission surface are mutually connected. When the torque transmitted to and the torque transmitted is equal to or greater than a predetermined value, a concave portion or a convex portion having an inclined surface that causes slippage between the torque transmission surface and the torque transmission surface is included.

  Therefore, a constant frictional force is always generated between the inclined surface of the torque transmission surface of the first annular member 80 and the inclined surface of the torque transmission surface of the second annular member 81. When the torque transmitted from the handle knob 70 to the nut 71a is less than a predetermined value, the inclined surface of the torque transmitting surface cannot get over the inclined surface of the torque transmitting surface and is engaged with each other while being engaged with each other. doing. Then, the torque of the handle knob 70 is transmitted to the nut 71a by this engagement, and the bolt shaft 7a screwed with the nut 71a is screwed back and forth.

  On the other hand, when the torque transmitted from the handle knob 70 to the nut 71a exceeds a predetermined value, the inclined surface of the torque transmitting surface of the first annular member 80 becomes the inclined surface of the torque transmitting surface of the second annular member 81. Slip occurs between the two. As a result, the second annular member 81 having the torque transmission surface is retracted against the coil spring 82, and the engagement between the two is released by the inclined surface of the torque transmission surface getting over the inclined surface of the torque transmission surface. . Therefore, even if the handle knob 70 is rotated in this state, the handle knob 70 only rotates around the nut 71a, and torque is not transmitted from the handle knob 70 to the nut 71a.

  Further, a vertical surface substantially orthogonal to the torque transmission surface is formed at the rear end of the inclined surface of the torque transmission surface of the first annular member 80, and the inclined surface of the torque transmission surface of the second annular member 81 is formed. A vertical surface substantially orthogonal to the torque transmission surface is formed at the rear end. The vertical surface of the torque transmission surface and the vertical surface of the torque transmission surface are in contact with each other and engaged when the handle knob 70 is rotated so that the pressing plate 4a moves backward from the side wall of the bathtub. Therefore, when the handle knob 70 is rotated so that the pressing plate 4a moves backward from the side wall of the bathtub, the handle knob 70 and the nut 71a always rotate in synchronism regardless of the magnitude of the transmitted torque.

  As shown in FIG. 1, the side cover 15 of the fixed frame 2a is attached so as to cover the outer surface of the vertical portion 20a of the fixed frame 2a. The side cover 15 is formed with a through hole for accommodating the upper grip 11. The pressing plate 4a is attached so as to protrude from the inner surface of the vertical portion 21a of the fixed frame 2a. The handle knob 70 is attached to the side cover 15.

  On the other hand, as shown in FIG. 5, the movable frame 3a is formed in an L shape and includes a horizontal portion 30a and a vertical portion 31a. With the main body 10a attached to the side wall of the bathtub, the horizontal portion 30a extends in the horizontal plane, and the vertical portion 31a extends downward from the end of the horizontal portion 30a and extends in the vertical plane. The horizontal portion 31a of the movable frame 3a is disposed so as to face each other with two small reinforcing ribs 23a sandwiched between the movable frame 3a and the fixed frame 2a, and the vertical portion 31a of the movable frame 3a. First and second leg portions 32a extending in a direction substantially orthogonal to are formed. In a state where the movable frame 3a is attached to the fixed frame 2a, the movable frame 3a is configured so that the first and second leg portions 32a are in sliding contact with the reinforcing rib 23a with two small reinforcing ribs 23a interposed therebetween. The horizontal portion 30a of the movable frame 3a is fixed to the fixed frame 2a by slide locking / releasing means described later.

  The pressure receiving plate support 50a attached to the vertical portion 31a of the movable frame 3a includes a first rotating member 54a, a second rotating member 55a, and a connecting plate 56a. The first rotating member 54a and the second rotating member 55a are screwed to each other so as to be rotatable. Further, the connecting plate 56a for supporting the press receiving plate 5a is screwed to the second rotating member 55a so as not to rotate.

  For this reason, in the handrail 1a for bathtubs of 1st Embodiment, the press receiving plate 5a can swing freely in a horizontal direction and / or a vertical direction, and has a play, The connection plate 56a of the press receiving plate support 50a Is attached to. In other words, the first connection portion 51a between the pressure receiving plate 5a and the connection plate 56a of the pressure receiving plate support 50a is allowed to have play due to play, and as a result, the pressure receiving plate 5a The angle can be adjusted to swing in all directions.

  The pressure receiving plate 5a cannot swing the neck at a large angle with respect to the pressure receiving plate support 50a, but has almost no resistance such as friction when swinging the neck, so it fits perfectly with the side wall of the bathtub. Therefore, the head can be shaken very easily and accurately for a small angle change. That is, the 1st connection part 51a of the press receiving plate 5a and the press receiving plate support 50a performs the fine angle adjustment of the press receiving plate 5a accurately so that the press receiving plate 5a may closely_contact | adhere to the side wall of a bathtub. To work for.

  The pressing plate 4a attached to the vertical portion 21a of the fixed frame 2a, like the pressing receiving plate 5a, can swing freely in the horizontal direction and / or the vertical direction, and has play, to the tip end portion 72a of the bolt shaft 7a. It is attached. That is, the connecting portion 43a between the pressing plate 4a and the tip end portion 72a of the bolt shaft 7a is allowed to have play by providing play, and as a result, the pressing plate 4a can also swing freely in all directions. Angle adjusted.

  On the other hand, the pressure receiving plate support 50a is attached to the vertical portion 31a of the movable frame 3a so as to freely swing in the horizontal direction and without rattling. That is, in the case of the handrail 1a for a bathtub according to the first embodiment, the pressure receiving plate support 50a is an angle-adjustable connecting means having a hinge-like structure, and the second connecting portion of the pressure receiving plate support 50a. Since the play is not provided in 52a substantially, the 2nd connection part 52a can be moved smoothly, without rattling. Moreover, although the press receiving plate support 50a should just be attached to the vertical part 31a of the movable frame 3a so that angle adjustment is possible to a horizontal direction and / or a vertical direction, in the case of the handrail 1a for bathtubs of 1st Embodiment The hinge structure is pivotally supported on the vertical portion 31a of the movable frame 3a so as to be able to swing only in the horizontal direction.

  For this reason, the pressure receiving plate support 50a has a resistance such as friction when shaking the neck larger than that of the first connecting portion 51a between the pressure receiving plate 5a and the pressure receiving plate support 50a. Since the head can be smoothly swung with a large angle, the head can be swung very easily and quickly with respect to a large change in angle to roughly fit the side wall of the bathtub. That is, the pressure receiving plate support 50a is inferior in accuracy to the first connecting portion 51a between the pressure receiving plate 5a and the pressure receiving plate support 50a, but substantially the entire surface of the pressure receiving plate 5a is easy on the side wall of the bathtub. So as to make a large angle adjustment of the pressure receiving plate 5a quickly and smoothly.

  FIG. 6 shows an enlarged schematic diagram of the pressure receiving plate support 50a and the pressure receiving plate 5a of the bathtub handrail 1a according to the first embodiment. As shown in FIG. 6, in the handrail 1 a for the bathtub according to the first embodiment, the pressure receiving plate 5 a includes a first connecting portion 51 a that can accurately perform minute angle adjustment with a slight force. Although it requires a larger force than the first connecting portion 51a, it is attached to the movable frame 3a via the second connecting portion 52a capable of instantaneously adjusting a large angle, that is, a pressure receiving plate support 50a. It has the feature of being.

  For this reason, when the pressure receiving plate 5a is pressed against the side wall of the bathtub, first, the pressure receiving plate 5a is pressed by the pressure receiving plate support 50a so that the substantially entire surface of the pressure receiving plate 5a easily comes into contact with the side wall of the bathtub. Large angle adjustments are made quickly and smoothly. Next, the pressure receiving plate 5a is pressed by the first connecting portion 51a between the pressure receiving plate 5a and the pressure receiving plate support 50a substantially simultaneously with the large angle adjustment by the pressure receiving plate support 50a. The fine angle adjustment of the pressure receiving plate 5a is performed with high accuracy so that the plate 5a is in close contact with the side wall of the bathtub.

  For this reason, in the handrail 1a for bathtubs of 1st Embodiment, as shown in FIG. 13, since the press receiving plate 5a is easily angle-adjusted so that it may closely_contact | adhere to the curved surface shape etc. of a bathtub side wall, Can be firmly and securely held. Moreover, once the bathtub handrail 1a is fixed to the side wall of the bathtub, the first connecting portion 51a between the pressure receiving plate 5a and the pressure receiving plate support 50a is caused by a synergistic effect with the pressure receiving plate support 50a. Since the contact is made so as not to cause backlash, the play provided in the first connecting portion 51a between the pressure receiving plate 5a and the pressure receiving plate support 50a, and the angle adjustment of the pressure receiving plate 5a with respect to the side wall of the bathtub ( It is prevented that the clamping force by the pressure receiving plate 5a and the pressing plate 4a is suddenly weakened due to lack of following), or as a result, the handrail 1a for the bathtub is detached from the side wall of the bathtub.

  The schematic diagram which shows the 1st modification of the press receiving plate support 50a and the press receiving plate 5a of the handrail 1a for bathtubs of 1st Embodiment is shown by FIG. In this modification, the first connecting portion 51a ′ of the press receiving plate support 50a ′ has a hinge structure, and the connecting plate 56a ′ of the press receiving plate support 50a ′ is partially bent to The swing support point Q of the backing plate support 50a ′ is disposed within the pressure receiving surface of the pressure receiving plate 5a ′ (including a surface parallel to the pressure receiving surface and crossing the range of a). . Further, the press receiving plate 5a ′ is provided with play in the second connecting portion 52a ′ between the press receiving plate 5a ′ and the connecting plate 56a ′, so that the connecting plate 56a can swing freely in the horizontal direction and / or the vertical direction. 'Attached to.

  In the bathtub handrail 1a ′ that is fixed to the side wall of the bathtub by the clamping force of the pressure receiving plate 5a ′ and the pressure plate (not shown), the force transmitted from the movable frame 3a ′ to the pressure receiving plate 5a ′ is the pressure receiving plate. It is transmitted through a swinging fulcrum Q of the plate support 50a ′. For this reason, the swing support point Q of the pressure receiving plate support 50a ′ is within the pressure receiving surface of the pressure receiving plate 5a ′ (including a surface parallel to the pressure receiving surface and crossing the range of a). When arranged, the vector of the force transmitted through the swing support point Q of the pressure receiving plate support 50a ′ is directed in any direction with respect to the pressure receiving plate support 50a ′. In this case, the pressure receiving plate 5a 'passes through a predetermined fixed position on the pressure receiving surface, that is, the substantially swinging fulcrum Q (see FIG. 14a). Thus, the side wall of the bathtub can be held with a stable pressing force at all times.

  On the other hand, the schematic diagram which shows the 2nd modification of the press receiving plate support 50a and the press receiving plate 5a of the handrail 1a for bathtubs of 1st Embodiment is shown by FIG. In this modification, the first connecting portion 51a "of the pressure receiving plate support 50a" has a ball joint structure, and the connecting plate 56a "of the pressure receiving plate support 50a" has a flat plate shape, thereby The swing support point Q of the backing plate support 50a ″ is disposed within the pressure receiving surface of the pressure receiving plate 5a ″ (including a surface parallel to the pressure receiving surface and crossing the range of a). . Moreover, also in the press receiving plate 5a of the handrail 1a for bathtubs of 1st Embodiment shown by FIG. 6, the fulcrum Q of the swing of the press receiving plate support 50a is in the press receiving surface of the press receiving plate 5a ( (Including a surface parallel to the pressure receiving surface and crossing the range of a). Further, the press receiving plate 5a ″ is provided with play in the second connecting portion 52a ″ between the press receiving plate 5a ″ and the connecting plate 56a ″, so that the connecting plate 56a can swing freely in the horizontal direction and / or the vertical direction. Is attached to.

  In the bathtub handrail 1a ″ that is fixed to the side wall of the bathtub by the clamping force of the pressure receiving plate 5a ″ and the pressure plate (not shown), the force transmitted from the movable frame 3a ″ to the pressure receiving plate 5a ″ is the above-described force. As described above, the vibration is transmitted through the swing support point Q of the pressure receiving plate support 50a, 50a ". For this reason, the swing support point Q of the pressure support plate support 50a, 50a" is used as the pressure support plate 5a, 5a ". The force vector transmitted through the fulcrum fulcrum Q of the pressure receiving plate support 50a, 50a ″ is the swing angle of the pressure receiving plates 5a, 5a ″. Irrespective of this, it is impossible to pass through a predetermined fixed position on the pressure receiving surface, and an unspecified position on the pressure receiving surface is passed according to the swing angle of the pressure receiving plates 5a and 5a ″ ( (See Fig. 14b) Even on the receiving surface, it can produce a strong portion and a weak pressing force. Such distribution of the pressing force is such that the pressing force per unit area generated in the pressure receiving plates 5a, 5a "is uniform when the handrails 1a, 1a" for the bathtub are attached to the side walls of the bathtub where the thickness is not constant. Therefore, it is advantageous for preventing the bathtub side wall from being damaged while obtaining a strong clamping force.

  The swing support point Q means that the swinging function of the pressure receiving plate support members 50a and 50a 'is realized by a hinge structure like the pressure receiving plate support members 50a and 50a' shown in FIGS. In this case, it means a shaft portion Q that is pivotably connected to each other so that the angle can be adjusted, and like the pressure receiving plate support 50a ″ shown in FIG. 8, the pressure receiving plate support 50a ”. In the case where the swinging function of “is realized by the ball joint structure, it means the ball shaft and the center Q of the bearing portion that are pivotably connected to each other so that the angle can be adjusted.

  Moreover, the inside of the pressure receiving surface of the pressure receiving plates 5a, 5a ′, 5a ″ not only means the pressure receiving surface of the pressure receiving plates 5a, 5a ′, 5a ″ but also the direction of the arrow a in FIGS. As shown in the range, the pressure receiving plates 5a, 5a ′, 5a ″ are parallel to the pressure receiving surfaces of the pressure receiving plates 5a, 5a ′, 5a ″ and press the pressure receiving plates 5a, 5a ′, 5a ″ (within the range a). It is used including a surface cut parallel to the receiving surface. For this reason, not only arranging on the pressure receiving surface of the pressure receiving plate 5a ′ but also arranging it in the pressure receiving surface of the pressure receiving plate 5a ′ is a surface parallel to the pressure receiving surface of the pressure receiving plate 5a ′. And the meaning which arrange | positions this press receiving plate 5a '(within the range of a) on the surface cut off in parallel with the press receiving surface is also included. On the other hand, disposing the pressure receiving plates 5a and 5a ″ away from the pressure receiving surfaces means not only arranging the pressure receiving plates 5a and 5a ″ apart from the pressure receiving surfaces but also surfaces parallel to the pressure receiving surfaces of the pressure receiving plates 5a and 5a ″. In addition, the meaning of disposing the press receiving plates 5a, 5a ″ (within the range a) away from the surface cut parallel to the press receiving surface is also included.

[Second Embodiment]
FIG. 9 shows a cross-sectional view of the handrail 1b for a bathtub according to the second embodiment as seen from the direction of the line XX shown in FIG. 1, and FIG. 10 shows a hand for a bathtub according to the second embodiment. A cross-sectional view of the slide 1b viewed from the direction of the YY line shown in FIG. 1 is shown.

  The handrail 1b for the bathtub according to the second embodiment includes a fixed frame 2b disposed on the side wall of the bathtub, a bolt shaft 7b attached to the vertical portion 21b of the fixed frame via a nut 71b, and a horizontal direction and / or a vertical direction. To the pressing plate support 40b attached to the bolt shaft 7b so as to freely swing in the direction and without rattling, and to the pressing plate support 40b so as to freely swing in the horizontal direction and / or the vertical direction. A pressure plate 4b that is attached to face the side of the side wall of the bathtub, a movable frame 3b that is slidably attached to the fixed frame 2b, and a vertical portion 31b of the movable frame 3b that is It is comprised from the plate 4b and the press receiving plate 5b arrange | positioned facing the side surface of the side wall of the bathtub on the opposite side. Unlike the pressure receiving plate 5 of the bathtub handrail 1 shown in FIG. 1, the pressure receiving plate 5b is divided into a left and right pair and attached to the pressure receiving plate support 50b.

  In the handrail 1b for a bathtub according to the second embodiment, the handle knob 70 and the pressing plate 4b are connected by a bolt shaft 7b, a nut 71b, a torque transmission mechanism 8, and a pressing plate support 40b. The pressing plate 4b is attached to the pressing plate support 40b so as to swing freely in the horizontal direction and / or the vertical direction and with play. In other words, the first connecting portion 41b between the pressing plate 4b and the pressing plate support 40b is allowed to have play by providing play, and as a result, the pressing plate 4b can swing in all directions. Angle adjusted to. Similarly to the pressing plate 4b, the pressing receiving plate 5b is attached to the vertical portion 31b of the movable frame 3b so as to freely swing in the horizontal direction and / or the vertical direction and with play. In other words, the connecting portion 53b between the press receiving plate 5b and the vertical portion 31b of the movable frame 3b is allowed to play with play, and as a result, the press receiving plate 5b swings in all directions. The angle can be adjusted freely.

  The pressing plate 4b cannot swing the neck at a large angle with respect to the pressing plate support 40b, but has almost no resistance such as friction when swinging the neck, so that the pressing plate 4b fits perfectly with the side wall of the bathtub. The head can be shaken very easily and accurately for small angle changes. That is, the 1st connection part 41b of the press plate 4b and the press plate support tool 40b functions in order to perform fine angle adjustment of the press plate 4b accurately so that the press plate 4b may contact | adhere to the side wall of a bathtub. .

  On the other hand, the pressing plate support 40b is attached to the distal end portion 72b of the bolt shaft 7b so as to be swingable in the horizontal direction and without rattling. That is, in the case of the handrail 1b for a bathtub according to the second embodiment, the pressing plate support 40b is an angle-adjustable connecting means having a hinge-like structure, and the second connecting portion 42b of the pressing plate support 40b Since substantially no play is provided, the second connecting portion 42b can be moved smoothly without rattling. Further, the pressing plate support 40b may be attached to the distal end portion 72b of the bolt shaft 7b so that the angle can be adjusted in the horizontal direction and / or the vertical direction, but in the case of the handrail 1b for a bathtub according to the second embodiment, The hinge structure pivotally supports the tip 72b of the bolt shaft 7b so that the head can swing only in the horizontal direction.

  For this reason, the resistance of the pressing plate support 40b, such as friction when shaking the neck, is larger than that of the first connecting portion 41b between the pressing plate 4b and the pressing plate support 40b, but is larger than the bolt shaft 7b. Since the head can be swung smoothly at an angle, the head can be swung very easily and quickly for a large change in angle to roughly fit the side wall of the bathtub. That is, the pressing plate support 40b is inferior in accuracy to the first connecting portion 41b between the pressing plate 4b and the pressing plate support 40b, but the entire surface of the pressing plate 4b is easily in contact with the side wall of the bathtub. In addition, it functions to quickly and smoothly adjust the large angle of the pressing plate 4b.

  Thus, in the handrail 1b for bathtubs of 2nd Embodiment, the press plate 4b can perform 1st connection part 41b and 1st connection part 41b which can perform fine angle adjustment accurately with slight force. Although it requires a larger force, it has a feature that it is attached to the bolt shaft 7b via the second connecting portion 42b, that is, the pressing plate support 40b, capable of instantaneously adjusting a large angle. Yes.

  For this reason, when the pressing plate 4b is pressed against the side wall of the bathtub, the pressing plate support 40b first adjusts the angle of the pressing plate 4b so that the substantially entire surface of the pressing plate 4b comes into contact with the side wall of the bathtub easily. It is done quickly and smoothly. Next, the pressing plate 4b is substantially at the same time that the angle adjustment is performed by the pressing plate support 40b, and at the same time, the pressing plate 4b is connected to the first connecting portion 41b between the pressing plate 4b and the pressing plate support 40b. Minute angle adjustment of the pressing plate 4b is performed with high accuracy so as to be in close contact with the side wall.

  For this reason, in the handrail 1b for bathtubs of 2nd Embodiment, since the press plate 4b is easily angle-adjusted so that it may closely_contact | adhere to the curved surface shape of a bathtub side wall, etc., it clamps the side wall of a bathtub firmly and reliably. Can do. In addition, once the bathtub handrail 1b is fixed to the side wall of the bathtub, the first connecting portion 41b between the pressing plate 4b and the pressing plate support 40b is loose due to the synergistic effect with the pressing plate support 40b. Since the contact is made so as not to occur, the pressing is caused by the play provided in the first connecting portion 41b of the pressing plate 4b and the pressing plate support 40b, or the angle adjustment (following) of the pressing plate 4b with respect to the side wall of the bathtub is insufficient. It is prevented that the clamping force by the plate 4b and the pressure receiving plate 5b is suddenly weakened, or as a result, the bathtub handrail 1b is detached from the side wall of the bathtub.

[Third Embodiment]
FIG. 11 is an exploded perspective view showing components of the fixed frame 2c, the movable frame 3c, and the slide locking / releasing means 6 of the handrail 1c for a bathtub according to the third embodiment.

  The handrail 1c for bathtubs of 3rd Embodiment is a nut to the vertical part 21c of the fixed frame 2c arrange | positioned at the side wall of a bathtub, although not shown in figure like the handrail 1b for bathtubs of 2nd Embodiment. A bolt shaft attached via a bolt, a horizontal and / or vertical swingable and pressing plate support attached to the bolt shaft without rattling, and a horizontal and / or vertical swing A pressing plate 4c that is freely and freely attached to the pressing plate support and is disposed to face the side surface of the side wall of the bathtub, a movable frame 3c that is slidably attached to the fixed frame 2c, and a horizontal Is attached to the vertical portion 31c of the movable frame 3c so as to swing freely in the direction and / or the vertical direction, and has a play, and the side surface of the side wall of the bathtub opposite to the pressing plate 4c Is composed of a pressable plate 5c disposed oppositely (FIGS. 9 and 10).

  As shown in FIG. 11, the fixed frame 2 c of the handrail 1 c for a bathtub according to the third embodiment is formed in an L shape and includes a horizontal portion 20 c and a vertical portion 21 c. With the main body 10c attached to the side wall of the bathtub, the horizontal portion 20c extends in the horizontal plane, and the vertical portion 21c extends downward from the end portion of the horizontal portion 20c and extends in the vertical plane. The pressing plate 4c is attached so as to protrude from the inner surface of the vertical portion 21c of the fixed frame 2c. Although not shown, the handle knob 70 and the pressing plate 4c are connected by a pressing plate support, a bolt shaft, a nut, and a torque transmission mechanism. By turning the handle knob 70, the rotational force is transmitted from the handle knob 70 to the nut, and the bolt shaft screwed with the nut is screwed back and forth, so that it is perpendicular to the surface of the vertical portion 21c of the fixed frame 2c. The pressing plate 4c is moved forward and backward along.

  On the upper surface of the horizontal portion 20c of the fixed frame 2c, four reinforcing ribs 22c for reinforcing the fixed frame 2c and guiding the movable frame 3c to be slidable are formed. A fixing plate 80 is attached to the upper surface of the reinforcing rib 22c. The reinforcing rib 22c extends along a direction substantially orthogonal to the horizontal portion 20c of the fixed frame 2c. In this embodiment, the four reinforcing ribs 22c are formed in parallel to each other. The fixing plate 61 is formed in a plate shape, and is fixed between the two reinforcing ribs 22c on the inner side of the four reinforcing ribs 22c. The lower surface of the fixed plate 61 and the upper surface of the horizontal portion 20c are separated from each other by the reinforcing rib 22c, and a through hole 610 that penetrates the upper surface and the lower surface of the fixed plate 61 is formed in the fixed plate 61. Between the two inner reinforcing ribs 22c, a hole 24c for accommodating the column 62 of the slide locking / releasing means 6 is formed.

  On the other hand, the movable frame 3c is formed in an L shape and includes a horizontal portion 30c and a vertical portion 31c. With the main body 10c attached to the side wall of the bathtub, the horizontal portion 30c extends in the horizontal plane, and the vertical portion 31c extends downward from the end of the horizontal portion 30c and extends in the vertical plane. The first and second leg portions 32c protrude from the back surface of the horizontal portion 30c of the movable frame 3c. The two leg portions 32c are formed in a shape in which the end portion extending along the direction orthogonal to the plane of the vertical portion 31c is folded downward in the horizontal portion 30c. The two leg portions 32c are formed with a space therebetween and extend along a direction orthogonal to the vertical portion 31c. The movable frame 3c is disposed between the reinforcing ribs 22c so as to be in sliding contact with the two reinforcing ribs 22c, and is fixed to the fixed frame 2c by the slide locking / releasing means 6.

  A slit 33c is formed in the horizontal portion 30c of the movable frame 3c. The slit 33c is a hole that penetrates the front surface and the back surface of the horizontal portion 30c. A plurality of circular holes 34 (FIGS. 2 and 9) are formed as first engaging portions on the back surface of the horizontal portion 30c of the movable frame 3c. The plurality of circular holes 34 are arranged along the direction in which the movable frame 3c extends. Further, the bottom of the circular hole 34 is formed by the horizontal portion 30c of the movable frame 3c, and a slit 33c is formed at the bottom. In addition, although the space | interval in which a some hole is arranged is not specifically limited, In this embodiment, the circular hole 34 is continuously formed so that a part of periphery may mutually overlap.

  The slide locking / releasing means 6 is attached on the horizontal portion 20c of the fixed frame 2c. The slide locking / releasing means 6 includes a column 62 as a second engagement portion, a rod-shaped connection portion 63 connected to the column 62, and an operation portion 60 connected to the opposite side of the column 62 in the connection portion 63. And a spring 64 as a biasing member for biasing the operation unit 60 and a lock member 65 inserted between the cylinder 62 and the operation unit 60.

  In the slide locking / releasing means 6, when the user is not operating the operation unit 60, the spring 64 biases the operation unit 60 from the bottom to the top. At this time, the column 62 connected to the operation unit 60 via the connecting portion 63 is also urged from the bottom to the top, that is, from the bottom toward the circular hole 34 on the back surface of the horizontal portion 30 of the movable frame 3. The upper part of the cylinder 62 is accommodated in the circular hole 34 and the cylinder 62 and the circular hole 34 are engaged with each other. In a state where the cylinder 62 and the circular hole 34 are engaged (FIGS. 2 and 9), the movable frame 3c is not slid in a direction away from the fixed frame 2c or a direction approaching the fixed frame 2c. Locked on top.

  In the slide locking / releasing means 6, when the user pushes down the operation unit 60 against the bias of the spring 64, the column 62 connected to the operation unit 60 also moves down, and the column 62 And the circular hole 34 are disengaged. In this embodiment, the pushing stroke of the operation unit 60, that is, the depth at which the operation unit 60 can be pushed downward is set so that the lower surface of the flange and the fixed frame 2c when the cylinder 62 is engaged with the circular hole 34 are used. Is equal to the distance from the upper surface of the horizontal portion 20c.

  Further, as shown in FIGS. 2 and 9, the lock member 65 having a flat bottom surface is slid so that the lock portion of the lock member 65 is sandwiched between the operation portion 60 and the fixing plate 61. By doing so, the user cannot push the operation unit 60 downward. By making the thickness of the lock portion of the lock member 65 equal to the pushing stroke of the operation portion 60, the operation portion 60 is pushed in when the lock portion is sandwiched between the operation portion 60 and the fixed plate 61. Can not be.

  Thus, the column 62 of the slide locking / releasing means 6 is disposed so as to engage with the circular hole 34 of the fixed frame 2c, that is, between the back surface of the movable frame 3c and the fixed frame 2c. Since the column 62 is coupled to the operation unit 60 disposed on the surface side of the movable frame 3c by the coupling unit 63, the user operates the operation unit 60 from the surface side of the movable frame 3c to thereby move the movable frame 3c. The cylinder 62 on the back side can be separated from the circular hole 34. In this way, the user can be prevented from touching the circular hole 34 or the cylinder 62.

  Further, since the contact surface between the circular hole 34 and the cylinder 62 is a surface orthogonal to the back surface of the movable frame 3c and includes a surface that is not parallel to the sliding direction of the movable frame 3c, the user operates the operation unit 60. As long as the slide locking / releasing means 6 is pushed against the bias by the spring 64 and the column 62 on the back surface side of the movable frame 3c is not separated from the circular hole 34, the circular hole 34 and the column 62 are connected to the movable frame 3c. In a plane that is not parallel to the sliding direction, and prevents the movable frame 3c from sliding. In this way, it is possible to prevent the movable frame 3c from being accidentally slid.

  The user pushes the slide locking / releasing means 6 against the urging force of the spring 64 by operating the operation unit 60 when moving the movable frame 3c close to the wall surface of the bathtub or away from the wall surface of the bathtub. The movable frame 3c can be slid. Thus, since the movable frame 3c can be slid in any direction by the same operation, the operation is easy.

  Moreover, in the handrail 1c for bathtubs of the handrail 1c for bathtubs concerning 3rd Embodiment, the circular hole 34 is a recessed part of the side peripheral surface shape of a cylinder, The vertical surface of the circular hole 34 and the vertical surface of the column 62 are as follows. Since it has a cylindrical side peripheral surface shape, even if the column 62 rotates in the circumferential direction during the sliding of the movable frame 3 c, the column 62 is easily received in the circular hole 34.

  Further, in the bathtub handrail 1c of the third embodiment, since the slit 33c of the movable frame 3c is an opening whose peripheral edge is closed, when the movable frame 3c is slid, the connecting portion of the slide locking / releasing means 6 is provided. 63 moves relatively inside the periphery of the slit 33c, and the sliding range of the movable frame 3c on the fixed frame 2c can be regulated so as not to rattle.

  The other configurations and effects of the handrail 1c for a bathtub according to the third embodiment are the same as those of the handrail 1b for a bathtub according to the second embodiment.

[Fourth Embodiment]
FIG. 12 is an exploded perspective view showing components of the fixed frame 2d, the movable frame 3d, and the slide locking / releasing means of the bathtub handrail 1d according to the fourth embodiment.

  The handrail 1d for the bathtub according to the fourth embodiment is similar to the handrail 1b for the bathtub according to the second embodiment, and a fixed frame 2d disposed on the side wall of the bathtub and a nut to the vertical portion 21d of the fixed frame (not shown). A bolt shaft attached via a bolt, a horizontal and / or vertical swingable and pressing plate support attached to the bolt shaft without rattling, and a horizontal and / or vertical swing A pressing plate 4d that is freely and freely attached to the pressing plate support, is arranged to face the side surface of the side wall of the bathtub, a movable frame 3d that is slidably attached to the fixed frame 2d, and a horizontal Is attached to the vertical portion 31d of the movable frame 3d so as to swing freely in the direction and / or the vertical direction, and has a side surface of the side wall of the bathtub opposite to the pressing plate 4d Is composed of a pressable plate 5d which are arranged oppositely (FIGS. 9 and 10).

  As FIG. 12 shows, the fixed frame 2d of the handrail 1d for bathtubs of 4th Embodiment is formed in the L-shape, and contains the horizontal part 20d and the vertical part 21d. With the main body 10d attached to the side wall of the bathtub, the horizontal portion 20d extends in the horizontal plane, and the vertical portion 21d extends downward from the end of the horizontal portion 20d and extends in the vertical plane. The pressing plate 4d is attached so as to protrude from the inner surface of the vertical portion 21d of the fixed frame 2d. Although not shown, the handle knob 70 and the pressing plate 4d are connected by a pressing plate support, a bolt shaft, a nut, and a torque transmission mechanism. By turning the handle knob 70, the rotational force is transmitted from the handle knob 70 to the nut, and the bolt shaft screwed with the nut is screwed back and forth, so that it is perpendicular to the surface of the vertical portion 21d of the fixed frame 2d. Accordingly, the pressing plate 4d is moved forward and backward.

  A plurality of screw holes 25d and 35d are formed in the horizontal portion 20d of the fixed frame 2d and the horizontal portion 30d of the movable frame 3d. In this embodiment, two screw holes 25d are formed in the fixed frame 2d, and four screw holes 35d are formed in the movable frame 3d. The directions are perpendicular to the vertical portion 21d of the fixed frame 2d and the vertical portion 31d of the movable frame 3d. That is, they are arranged side by side along the longitudinal direction of the horizontal portion 20d of the movable frame 3d.

  The horizontal portion 20d and the vertical portion 21d of the fixed frame 2d are respectively provided with a small reinforcing rib 23d for reinforcing the fixed frame 2d and a large reinforcing rib 22d for guiding the movable frame 3d to be slidable. In parallel to the horizontal portion 20d and the vertical portion 21d.

  On the other hand, the horizontal portion 30d of the movable frame 3d includes first and second leg portions 32d extending downward from the lower surface of the horizontal portion 30d. The first and second leg portions 32d are arranged in parallel with a gap therebetween, and continuously extend across the horizontal portion 30d and the vertical portion 31d of the movable frame 3d. Four screw holes 35d are formed in the horizontal portion 30d of the movable frame 3d between the first leg portion 32d and the second leg portion 32d. The screw hole 35d penetrates from the upper surface to the lower surface of the horizontal portion 30d.

  In the bathtub handrail 1d of the fourth embodiment, when the fixed frame 2d and the movable frame 3d are assembled, the first and second leg portions 32d of the movable frame 2d slide on the large reinforcing rib 22d at the center. Arranged to touch. One side surface (inner surface) of the first leg portion 32d and the second leg portion 32d of the movable frame 3d is in sliding contact with the side surface of the large reinforcing rib 22d, and the first and second leg portions 32d of the movable frame 3d. Is in sliding contact with the upper surface of the horizontal portion 20d of the fixed frame 2d. The horizontal portion 30d of the movable frame 3d is placed on the horizontal portion 20d of the fixed frame 2d, and the screw 36d is passed through the screw hole 35d and the screw hole 25d, so that the movable frame 3d is fixed on the fixed frame 2d. In this embodiment, since four screw holes 35d are formed, depending on which screw hole 25d, 35d is used to fasten the fixed frame 2d and the movable frame 3d, The overlapping width of the movable frame 3d with the horizontal portion 30d can be changed, and the distance between the pressing plate 4d and the pressing receiving plate 5d can be adjusted.

  In the handrail 1d for a bathtub according to the fourth embodiment, when the user grabs the side grip 13d and goes in and out of the bathtub, a load is applied to the fixed frame 2d and the movable frame 3d in the vertical plane. The fixed frame 2d is formed with a large reinforcing rib 22d extending over the horizontal portion 20d and the vertical portion 21d. Since the movable frame 3d is screwed to the reinforcing rib 22d, the user holds the side grip 13d. When grasping and going in and out of the bathtub, the strength of the fixed frame 2d against the load applied in the vertical plane can be improved.

  Similarly, since the first leg portion 32d and the second leg portion 32d are formed on the movable frame 3d, the strength of the movable frame 3d with respect to such a load in the vertical plane is improved. Further, in a state where the movable frame 3d is attached to the fixed frame 2d, the first and second leg portions 32d are arranged so as to face the large reinforcing rib 22d, and are reinforced so as to be in sliding contact with the large reinforcing rib 22d. Since the rib 22d is sandwiched, it is possible to prevent the movable frame 3d from rattling in a direction parallel to the vertical portion 31d of the movable frame 3d in the horizontal plane, and the fixed frame 2d and the movable frame 3d are loaded in the vertical plane. It is possible to prevent the strength from being lowered when it is applied. Further, by screwing the movable frame 3d to the large reinforcing rib 22d, the screw can be screwed deeper than when directly screwing to the horizontal portion 20d of the fixed frame 2d, so that the mounting strength of the movable frame 3d is increased. Can be improved.
