[Figure 10] This is a diagram illustrating an example of handrail installation in this embodiment. [Modes for carrying out the invention]

[0008] Generally, handrail devices are known for being installed and used in Western-style toilets. Users can use the handrail to lower themselves when sitting on the toilet seat, and to stand up when getting off the toilet seat. In addition, users can maintain a stable posture and strain while defecating by gripping the handrail or resting their arms on it.

[0009] Such handrail devices typically have a fixed shape for both sale and use. Therefore, the armrests attached to the top of the handrail usually have different shapes at the front and back, and the mounting direction is fixed. Furthermore, to prevent installers from making mistakes in the mounting direction, the mounting direction for the handrail to the base is usually fixed, and the structure is often designed so that it cannot be installed in a direction other than the intended orientation (for example, in the opposite direction after rotating 180 degrees, or in the direction after rotating 90 degrees to the left or right).

[0010] However, in recent years, with the increasing demand for home care and the growing number of people requiring support or care, the use of handrails in homes has become more common. Because toilet shapes vary depending on the residence, there is a growing need to install handrails that are tailored to the specific toilet layout. Furthermore, given the diverse sizes of toilet spaces and the physical condition of users (for example, their level of support or care needs), there is a growing need to appropriately install handrails in toilets to accommodate these various factors.

[0011] Furthermore, in recent years, universal design has become a focus even in devices such as handrails. As a result, some users have expressed a need to reduce the sense of discomfort that can arise when handrails are installed, as they can give the impression of being caregiving equipment. For example, compared to typical handrails, there is a growing desire for designs that blend in with (harmonize with) the interior space, or for designs that are less recognizable as caregiving equipment, indistinguishable from ordinary furniture, and blend into the home environment.

[0012] To solve one or more such problems, one form of the handrail device in the present disclosure will be described below with reference to the drawings. Specifically, the case where the handrail device of the present disclosure is applied to a toilet handrail device used in a Western-style toilet will be described, but the scope to which the present disclosure is applied is not limited to this embodiment. In addition, the shading and shadows shown in each figure are all for specifying the shape of the three-dimensional surface. Also, the lines, wireframes, etc. shown in the changing parts of the surface shape shown in each figure are all for specifying the shape of the three-dimensional surface.

[0013] [1. Overall Configuration] FIG. 1 is a perspective view showing the whole of the handrail device 1. The handrail device 1 can attach and detach one or two handrails 3 to and from a base 7 serving as a base. The handrail 3 has a telescopic support column 5 and an armrest 10. FIG. 2 is a diagram (exploded view) for explaining the structure of the handrail 3. FIG. 3 is a plan view of the base 7 seen from the front side.

[0014] The handrail device 1 is, for example, a device used in a toilet. For example, the handrail device 1 is attached to a Western-style toilet. The handrail device 1 can assist in the sitting, standing up, excretion movements of a user in a Western-style toilet, and maintaining the posture, etc.

[0015] As an example, the handrail device 1 is provided with telescopic handrails 3 on the left and right of the base 7. The support column 5 of the handrail 3 is detachably fixed to the base 7 at the lower end and an armrest 10 is provided at the upper end. In addition, the support column 5 is, in this embodiment, circular and cylindrical and has a hollow pipe shape, but may be, for example, other shapes (rectangular shape, elliptical column shape, etc.).

[0016] Also, the support column 5 may be made of metal, but may be made of other materials such as wood, plastic (reinforced plastic, fiber-reinforced plastic, etc.). Also, the handrail 3 (support column 5) is shown as telescopic as an example in this embodiment, but may also have a non-telescopic shape (the height is fixed).

[0017] In the handrail device 1, it is preferable that the handrails 3 are provided in a pair on the left and right. Depending on the installation situation of the handrail device 1, only one of the left and right handrails 3 may be provided. Preferred installation situations where only one handrail 3 is provided on the left or right include, for example, when one side is a wall surface, or when there is a request that it is more preferable to have only one handrail 3 in terms of the location of the toilet entrance and the relationship between the position of the toilet entrance and the toilet bowl. As for the relationship with the toilet entrance, for example, first, when a user enters the toilet from the side, it is desired to provide a handrail only on the back side so as not to obstruct the entrance side, or second, when entering the toilet from the side, a handrail is provided only on the entrance side to support the user's sitting and standing up. Here, in the drawing of FIG. 1, the left - right direction is indicated by arrows as the right (R) direction and the left (L) direction. Similarly, the front - rear direction is indicated by arrows as the front (F) direction and the rear (B) direction. Also, the direction orthogonal to the left - right direction and the front - rear direction is defined as the up - down direction, and is indicated by arrows as the up (U) direction and the down (D) direction.

[0018] Also, the handrails 3 have the same shape for the entire handrails installed on the left and right. Therefore, for example, they can be installed on either the left or right side with respect to the base 7. Also, as will be described later, the handrails 3 can be installed with the front - rear direction reversed.

[0019] The support column 5 is configured to be height - adjustable vertically by the movement of the first support column 52 and the second support column 54 in a fitted state. The first support column 52 and the second support column 54 can be fixed in height by, for example, fixing means (not shown). As an example of the fixing means, a screw member may be fitted into holes provided in the first support column 52 and the second support column 54 to fix the positions of the first support column 52 and the second support column 54. Also, the fixing means may fix the first support column 52 and the second support column 54 by other means, for example, using a latch structure or the like to fix the positions of the two support columns.

[0020] The first support column 52 in this embodiment has a curved shape at the top. For example, the first support column 52 is curved so as to protrude in the front-rear direction of the handrail device 1 from the center line (the center line that fits with the second support column 54). For example, the first support column 52 is curved so that the top has a fishhook shape (a "U" shape in side view). The curvature of the first support column 52 creates a space in the curved portion below the armrest 10 of the handrail 3. For example, the handrail 3 can be positioned so that a toilet control panel or the like is located in the curved space created between the armrest 10 and the support column 5.

[0021] Furthermore, the first support column 52 is provided with an armrest 10 at its upper end. For example, in this embodiment, the first support column 52 and the armrest 10 may be connected via a connecting member or directly connected. Also, the first support column 52 and the armrest 10 may be fixed together with screws. In addition, the armrest 10 may be provided with a guide member (for example, a rail structure that acts as a guide) on its bottom surface, and the armrest 10 and the first support column 52 may be connected using the guide member. Furthermore, the armrest 10 may be fixed to the first support column 52 in a way that prevents it from being detached, such as by welding or integrally forming, or it may be fixed to the first support column 52 in a way that allows it to be detached.

[0022] The second support column 54 has a fixing member 56 on its lower end. It is detachably fixed to the base 7 via the fixing member 56. For example, the fixing member 56 has one or more screw holes 56a. The base 7 also has multiple screw holes 72 for fixing the fixing member 56 with screws. The support column 5 may also be fixed to the base 7 by screwing together the screw holes 56a and the screw holes 72 of the base 7.

[0023] Here, the handrail 3 may have a structure that prevents it from being attached to the base 7 in a specific direction. For example, a structure such as attaching a rivet to the back of the fixing member 56 may be used to prevent the handrail 3 from being attached to the base 7 when rotated 90 degrees. This allows the handrail 3 of this embodiment to be attached in various ways, such as swapping left and right, or swapping front and back (180-degree rotation). However, the handrail 3 can be restricted from being attached to the base 7 when it is rotated 90 degrees (for example, when the armrest 10 is parallel to the left and right direction of the handrail device 1, or when it is oriented sideways). As a method of restricting the attachment direction, for example, the arrangement of the screw hole 56a of the fixing member 56 and the screw hole 72 of the base 7 may be set to a specific arrangement. For example, by changing the lengths of the vertical and horizontal sides of the fixing member 56 (making it rectangular), it is possible to prevent the handrail 3 from being attached to the base 7 when it is rotated 90 degrees.

[0024] Furthermore, the front and back of the handrail 3 (180-degree rotation) can be achieved not only by attaching and detaching the fixing member 56, but also by removing the support column 52 from the support column 54 and reattaching the support column 52 in reverse.

[0025] Thus, the screw holes 72 are positioned so that the handrail 3 can be installed with its front-to-back orientation reversed. Even if the front-to-back orientation of the handrail 3 is reversed, it can still be properly screwed into the screw holes 72 using the fixing member 56.

[0026] For example, users can install the handrail 3 so that the curved portion of the first support column 52 protrudes towards the rear, or so that the curved portion of the first support column 52 protrudes towards the front.

[0027] Furthermore, although this embodiment describes an example in which the support column 5 and the base 7 are fixed together with screws, the second support column 54 may also be fixed to the base 7 via an engaging member.

[0028] The base 7 is a platform that secures the left and right support columns 5, and is U-shaped in plan view, as shown in Figure 3. The base 7 also has a space in the center of its rear side in the left-right direction. For example, by positioning the handrail device 1 so that a Western-style toilet bowl is located within the space of the base 7, users can utilize the handrail device 1 when using the toilet.

[0029] Furthermore, the base 7 may have a gripping portion in part. The gripping portion may be configured as, for example, a rectangular (elliptical, oblong) hole. For example, a user can lift or carry the base 7 by inserting their hand (fingers) into the gripping portion. Also, by having a gripping portion on the base 7, maintenance workers or companies that deliver welfare equipment to users' homes can easily carry the base 7 by using the gripping portion.

[0030] [2. Armrest Structure] Figure 4 shows the armrest 10. Figure 4(a) is a plan view of the armrest 10, Figure 4(b) is a side view of the armrest 10, and Figure 4(c) shows a cross-section of the armrest 10 near the center in the longitudinal direction. The shape of the armrest 10 can be a combination of one or more of the following features.

[0031] Here, the armrest 10 is preferably made of a soft material. For example, the armrest 10 is preferably made of a material that is easy for the user to grip, such as urethane (ether-based polyurethane), but it may also be made of wood, plastic, or stainless steel. Furthermore, the armrest 10 may be made of a material that is resistant to mold, or it may be treated with an antibacterial coating.

[0032] The armrest 10 has, for example, a length of 250 mm to 390 mm in the longitudinal direction and a length of 120 mm to 180 mm in the transverse direction. The armrest 10 is also symmetrical in the front-to-back direction from the center in the longitudinal direction. Furthermore, the ends of the armrest 10 have a radius of R60 mm to R90 mm. The armrest 10 also has a thickness of 20 mm to 25 mm.

[0033] Furthermore, it is preferable that the armrest 10 has recesses (indentations) on the bottom surface of its longitudinal ends (both ends). For example, as shown in Figure 4(b), the armrest 10 has recesses 12 on its bottom surface. For example, it is preferable that the recesses 12 are shaped such that when a user is seated and grips the armrest, the indentations are in the areas where the fingers rest when gripping the armrest.

[0034] In this way, for example, the presence of the recess 12 makes it easier for the user to grasp the armrest 10. In particular, the shape makes it easy for the user to grasp the armrest 10 when standing up or when using the toilet. This is because when a user stands up, they need to shift their center of gravity forward from the seat to their feet, and they pull their body forward to shift their center of gravity. At that time, the recess 12 on the back of the armrest 10 and the slope of the side make the armrest 10 easy to grip and easy for the fingers to get a hold of. Furthermore, it is preferable that the recess 12 is recessed by about 2 to 3 mm relative to the thickness of the armrest 10.

[0035] Furthermore, it is preferable that the recess 12 has the same shape at both ends. By making the recess 12 the same shape, even if the orientation of the armrest 10 in the front-to-back direction is reversed and it is fixed to the base 7, the user can use the armrest 10 without feeling any discomfort. Even if the armrest 10 does not have a recess 12, it is preferable that the shape of both ends in the longitudinal direction is the same.

[0036] Furthermore, the armrest 10 may have inclinations at its longitudinal ends (both ends). As shown in Figure 4(b), the inclinations at the longitudinal ends of the armrest 10 make it easier for the user to grip the armrest 10. For example, the inclination angle θ1 is preferably 20 to 30 degrees, and for example, it may be 25 degrees. In particular, the combination of the shape of the recess 12 and the inclination makes it easy for the user to grasp, easy to grip when standing up, and easy to strain when defecating. It is also preferable that the inclination angle be the same in the longitudinal direction.

[0037] Furthermore, the armrest 10 may have a recess on its upper side, as shown in Figure 4(c). That is, it may have a shape that curves inward towards the center along the shorter side. Because the armrest 10 has a shape that curves inward towards the center, it is easy for the user to rest their arms on it. Also, even if the user rests their arms on the armrest 10, the recess makes it difficult for their arms to fall off. Therefore, for example, even if the user takes a long time to defecate, they can comfortably rest their arms.

[0038] Furthermore, it is preferable that the upper surface of the longitudinal end (both ends) of the armrest 10 be a flat plane. That is, in the longitudinal direction of the armrest 10, the front and rear regions have flat surfaces. Also, in the longitudinal direction of the armrest 10, the central region is formed to be recessed compared to the ends. In this case, it is preferable that the recessed portion on the upper surface of the armrest 10 extends over the entire area other than the front and rear regions. Thus, the front and rear regions of the armrest 10 have flat surfaces, while the central region has a recessed shape in the center of the surface compared to the ends.

[0039] Because the longitudinal end of the armrest 10 is wide and flat, users can place their hands on the end to stably support their body when they first enter the toilet.

[0040] Furthermore, because the upper surface of the longitudinal end of the armrest 10 is flat, users can easily support their bodies by shifting their weight onto the flat area when standing up. Also, because the upper surface of the longitudinal end of the armrest 10 is flat, it is easier to wipe clean.

[0041] Furthermore, the armrest 10 may have inclines on both sides (both sides) in the shorter direction. For example, as shown in Figure 4(c), by providing inclines on both sides of the armrest 10, the shape becomes easy for the user's fingers to grip from any direction. For example, the armrest 10 can be approached by the user from the front or from the side. This makes it easier for the user to change direction by holding the armrest 10. Also, the user can change direction more easily by holding the armrest 10 with both hands.

[0042] Here, the inclination angle of both sides is preferably 10 to 20 degrees, and more preferably 15 degrees.

[0043] Furthermore, it is preferable that the armrest 10 be made to a length that takes into account the user's physique. For example, the length of the armrest 10 should be such that it is possible to ensure the distance from the average posterior edge of the olecranon to the grip axis of the user. For example, according to the "Japanese Human Body Dimensions Data Book 2004-2006 (Japan Human Life Engineering Research Center)," the average distance from the posterior edge of the olecranon to the grip axis for 95% of the median age group between 65 and 74 years old is 351 mm for men and 325.8 mm for women. Therefore, the length of the armrest 10 in the longitudinal direction should be between 350 mm and 420 mm, preferably between 370 mm and 400 mm.

[0044] Similarly, the length of the armrest 10 in the shorter direction should be at least 60 mm, preferably about 90 mm, of the average diameter of the wrist circumference of an average subject.

[0045] Furthermore, the thickness of the armrest 10 should be at least 26 mm from the average length obtained by subtracting the palm length from the average hand length of a subject (in other words, the length of the middle finger), divided by 3, assuming a human grip.

[0046] [3. Examples of handrail installation] Now, let's explain an example of installing the handrail 3 in the handrail device 1.

[0047] [3.1 First installation example] Figure 6 shows an example where handrails 3 are installed on both the left and right sides of handrail device 1. Figure 6(a) is a schematic plan view of handrail device 1, and Figure 6(b) is a perspective view of handrail device 1. In this case, we assume that a toilet control device (for example, a sleeve remote control) is installed to the right (R) of handrail device 1.

[0048] Figure 6 shows that the handrail 3 is installed on the base 7 such that the protruding direction of the first support column 52 is in front of the handrail device 1, in order to avoid the remote control device. Also, the handrail 3 is installed towards the front of the base 7. In this case, the tip of the armrest 10 does not extend beyond the base 7. As shown in Figure 6(a), the front tip of the armrest 10 is installed in a position that does not exceed the position of the front tip of the base 7.

[0049] [3.2 Second installation example] Figure 7 shows an example where handrails 3 are installed on both the left and right sides of handrail device 1. Figure 7(a) is a schematic plan view of handrail device 1, and Figure 7(b) is a perspective view of handrail device 1. In this case, it is assumed that no toilet operating device (e.g., sleeve remote control) is installed.

[0050] Figure 7 shows that the handrail 3 is installed on the base 7 such that the protruding direction of the first support column 52 is behind the handrail device 1, in order to secure ample space in front of the handrail device 1. Furthermore, the handrail 3 is installed towards the rear of the base 7 in order to secure ample space in front of the handrail device 1. In this case, the armrest 10 is included within the range of the base 7. As shown in Figure 7(a), the front and rear ends of the armrest 10 are installed in positions that do not extend beyond the range of the base 7. [3.3 Third installation example] Figure 8 shows an example where handrails 3 are installed on both the left and right sides of handrail device 1. Figure 8(a) is a schematic plan view of handrail device 1, and Figure 8(b) is a perspective view of handrail device 1. In this case, a toilet control device (for example, a sleeve remote control) is installed on the right (R) side of handrail device 1, and it is assumed that the toilet is entered from the side (from the left).

[0051] Figure 8 shows that, in order to avoid the remote control device, the handrail 3A is installed on the base 7 such that the protruding direction of the first support column 52 is in front of the handrail device 1. Also, the handrail 3B, which is closer to the entrance, is installed on the base 7 such that the protruding direction of the first support column 52 is behind the handrail device 1 in order to secure a large space in front of the handrail device 1. In this way, the handrail device 1 can be installed by combining the installation methods of Figures 6 and 7 as the installation method of the handrails 3.

[0052] Furthermore, as shown in Figure 9, handrails 3A and 3B may be installed at different positions relative to the base 7. Figure 9(a) is a schematic plan view of the handrail device 1, and Figure 9(b) is a perspective view of the handrail device 1. Here, handrail 3A is installed towards the rear of the base 7, and handrail 3B is installed towards the front of the base 7.

[0053] [3.4 Fourth installation example] Furthermore, the handrail 3 may be installed in combination of orientations and positions. For example, Figure 10 shows an example where the handrail 3 is installed on one side of the handrail device 1. For example, Figure 10(a) shows a state in which the handrail 3A is installed to the right of the base 7 so that the protruding direction of the first support column 52 is towards the front of the handrail device 1. For example, when there is a wall on the right, the handrail 3A is installed only on the wall side. Also, even if there is a toilet control device, the handrail 3A is positioned so as not to get in the way.

[0054] Figure 10(b) shows the state in which the handrail 3B is installed to the left of the base 7 such that the protruding direction of the first support column 52 is towards the front of the handrail device 1. For example, when the entrance is on the right, the handrail 3A is installed only on the entrance side.

[0055] Figure 10(c) shows the handrail 3A installed to the right of the base 7 such that the protruding direction of the first support column 52 is towards the rear of the handrail device 1. In this case, if there is no toilet operating device, the handrail 3 is positioned to secure a wide space in front of it.

[0056] In addition, as shown in all the installation examples of this embodiment, regardless of how it is installed, the front end (tip) of the armrest 10 is positioned so as not to exceed the position of the front end (tip) of the base 7. That is, when the handrail device 1 is viewed from above, when the handrail 3 is installed, the front end of the armrest 10 is positioned so as not to exceed the range of the base 7. As a result, even if a user places their hand on the armrest 10, the handrail device 1 can stably support the user.

[0057] In this embodiment, the handrail 3 is positioned such that the front end (tip) of the armrest 10 does not exceed the end (tip) of the base 7. However, "not exceeding" means that slight dimensional changes that may occur due to manufacturing errors or displacement during use are permitted, and even if it slightly exceeds the limit, it is included within the technical scope of this disclosure as long as the above-described effects can be substantially achieved.

[0058] Furthermore, as mentioned above, the handrails 3 may be installed symmetrically, or they may not be installed in pairs. For example, one handrail (for example, the right side) may be installed on the base 7 such that the protruding direction of the first support column 52 is towards the rear of the handrail device 1, while the other handrail (for example, the left side) may be installed on the base 7 such that the protruding direction of the first support column 52 is towards the front of the handrail device 1.

[0059] Furthermore, as mentioned above, only one handrail 3 may be installed. Thus, in the handrail device 1, the handrail 3 should be installed as needed.

[0060] Furthermore, the same components can be used for the handrail 3 mentioned above. For the sake of explanation, we refer to them as handrail 3A and handrail 3B, but these may be made from the same component. In other words, only one type of handrail 3 is needed, and it can be shared with other handrail devices 1. In addition, the handrail 3 can be installed flexibly by changing the front-to-back orientation of the installation direction on-site, or by shifting the installation position of the base 7.

[0061] [4. Effects] According to the handrail device 1 of this disclosure, the handrail 3 can be installed by switching its position front to back to match the layout of the place where the handrail device 1 is to be installed. For example, by utilizing the space created by the curved portion of the handrail 3, the toilet control panel can be efficiently positioned.

[0062] Furthermore, the curved portion of the handrail 3 creates a space, which is expected to prevent the support post 5 of the handrail 3 from hitting the user's feet when sitting down on the toilet, standing up from the toilet, or turning around in the toilet. It is also expected to prevent the user's knees from hitting the support post 5 of the handrail 3 when sitting down on the toilet or standing up. In particular, if the support post 5 was made of metal, it would become cold in winter, leading to discomfort when the user touched it. By preventing the user from touching the support post 5, this discomfort can be avoided.

[0063] Furthermore, by installing handrail 3 towards the rear (with the curved portion protruding to the rear), the space in front of handrail 3 can be made wider. As a result, the design of handrail device 1 is visually less oppressive, allowing it to blend naturally into the toilet space and reduce the psychological burden on users. Here, the psychological burden on users refers to the psychological burden on the care recipient and the caregiver of providing and receiving care. In this way, by using handrail device 1, it is possible to provide a handrail device that realizes universal design.

[0064] [5. Variant] This disclosure is not limited to the embodiments described above, and various modifications are possible. In other words, embodiments obtained by combining technical means that are appropriately modified within the scope of this disclosure are also included in the technical scope.

[0065] Furthermore, we intend to obtain rights to any of the technologies described in the specification through amendments or divisional applications, etc.

[0066] Furthermore, the scope of this disclosure is not limited to the configurations explicitly described in the specification, but also includes combinations of the technologies disclosed herein. While the configurations for which patent protection is sought are described in the attached claims, there is no intention to exclude them from the technical scope simply because they are not described in the claims.

[0067] Furthermore, the phrases "in the case of..." and "when..." in the above-mentioned specification are explained as examples only, and do not represent a configuration limited to those described. Even for configurations other than those described, we disclose information that would be obvious to a person skilled in the art, and we intend to acquire rights to such information.

[0068] Furthermore, although the handrail device 1 of this embodiment has been described as being preferably used for use with a Western-style toilet, it can of course be used with other chairs and the like. [Explanation of Symbols]
