[0035] Hereinafter, an embodiment of the temporary handrail disclosed here will be described with reference to the drawings. In addition, the embodiments and examples described here illustrate a preferred mode of the invention of the present application, but the invention of the present application is not limited thereto as long as not particularly mentioned. In addition, components and parts having the same function are denoted by the same reference numerals, and repeated descriptions are appropriately omitted or simplified.

[0036] Figure 1 It is a perspective view of the temporary handrail 10. Figure 2 It is a top view of the temporary handrail 10. As Figure 1 shown, the temporary handrail 10 includes a bottom plate 11 and handrails 12 and 13. As Figure 1 shown, the temporary handrail 10 is provided in front of the toilet 100. Here, the front, rear, left, and right of the temporary handrail 10 are determined in a state where the temporary handrail 10 arranged in front is observed from the toilet seat side of the toilet 100. In Figure 1 and Figure 2In the illustrated example, the armrest disposed on the left side of the user in the posture of sitting on the toilet is defined as the "left armrest", and the armrest disposed on the right side of the user is defined as the "right armrest". The left armrest 12 is disposed at a predetermined position on the rear and outer sides on the left side of the bottom plate 11. The right armrest 13 is disposed at a predetermined position on the front and inner sides on the right side of the bottom plate 11.

[0037] <Bottom plate 11>

[0038] Figure 3 is a perspective view of the bottom plate 11. As Figure 3 shown, the front-back direction and the left-right direction of the bottom plate 11 are predetermined. The bottom plate 11 is a substantially rectangular plate. The central portion at the rear side of the bottom plate 11 is recessed forward. As Figure 1 and Figure 2 shown, the bottom plate 11 is disposed in front of the toilet 100. The front portion of the toilet 100 enters the recessed portion 11a at the central portion of the rear side of the bottom plate 11. And, the rear side portions of the left and right side portions of the bottom plate 11 can be disposed on both sides of the front portion of the toilet 100.

[0039] The bottom plate 11 can be formed of, for example, a steel plate or a stainless steel plate. The bottom plate 11 can have such a weight that it can be carried and is not easily lifted when the weight of the user or caregiver is applied to the armrests 12, 13. The bottom plate 11 can also have a decorative plate mounted on its surface. In addition, a plate having a certain weight can be mounted on the back.

[0040] For the user, in order to use the armrests 12, 13 when using the toilet 100, it is assumed that there is a need to dispose the armrests 12, 13 close to the toilet 100 to a certain extent. As described above, the bottom plate 11 has the recessed portion 11a at the central portion of the rear side. From the viewpoint of disposing the armrests 12, 13 close to the toilet 100, the columns of the armrests 12, 13 can also be erected near the rear edge of the bottom plate 11 on both sides of the recessed portion 11a at the central portion of the rear side. However, on both sides of the recessed portion 11a at the central portion of the rear side, the width of the bottom plate 11 is narrowed. Therefore, if the position where the columns of the armrests 12, 13 are disposed is too close to the rear edge of the bottom plate 11, the bottom plate 11 may flex when the weight of the user is applied to the columns of the armrests 12, 13. If the bottom plate 11 flexes, the armrests 12, 13 may become unstable.

[0041] From the viewpoint of suppressing the flexure of the bottom plate 11 to a small value, it is sufficient for the bottom plate 11 to have the required rigidity as a whole. In Figure 1In the manner shown, the bottom plate 11 has a shape in which the whole is flat and the peripheral portion 11d bulges. With this shape, the rigidity of the bottom plate 11 is ensured. That is, compared with the case where the bottom plate 11 is a simple flat plate, the whole bottom plate 11 is less likely to flex. The angle at which the peripheral portion 11d bulges is gentler on the front side of the bottom plate 11 than on the rear side. And the columns 31 of the armrests 12 and 13 are installed at a position slightly forward without being too close to the edge on the rear side of the bottom plate 11.

[0042] A mat can be laid on the flat portion of the bottom plate 11, and the illustration is omitted. The mat can be set to substantially cover the upper surface of the bottom plate 11. The mat can be, for example, a detachable sheet or mat, or a so-called adsorption mat, etc. Even when a steel plate material is used for the bottom plate 11, by laying a mat, the feet can have a good touch, are not likely to slip, and the comfort of use can be improved. By appropriately disassembling, replacing or washing the mat, the surface of the bottom plate 11 can be kept clean.

[0043] On the bottom plate 11, mounting portions 11b and 11c are provided at predetermined positions where the armrests 12 and 13 are mounted. The armrest 12 is provided on the left side of the bottom plate 11. The armrest 13 is provided on the right side of the bottom plate 11. The mounting portions 11b and 11c are provided at two places that are offset in the front-rear direction on the left and right side portions of the bottom plate 11. In the present embodiment, as Figure 3 shown, six mounting holes 11b1 and 11c1 are respectively formed in the left and right mounting portions 11b and 11c of the bottom plate 11. The six mounting holes 11b1 and 11c1 are arranged at the four corners and the middle position of a substantially rectangular area that is long in the front-rear direction. The four front-side and four rear-side mounting holes among the six mounting holes 11b1 and 11c1 are respectively grouped into a set, and the mounting portions 11b and 11c are formed at two places that are offset in the front-rear direction. The two middle mounting holes 11b1 and 11c1 among the six mounting holes 11b1 and 11c1 are shared by the two mounting portions 11b and 11c that are offset in the front-rear direction. In addition, in the present embodiment, armrests are provided on both the left and right sides of the bottom plate 11, but as long as not specifically mentioned, the armrest can also be provided only on one of the left and right sides of the bottom plate 11.

[0044] In this embodiment, the peripheral portion 11d of the bottom plate 11 bulges. The bottom plate 11 has a flat shape except for the peripheral portion 11d. The mounting portions 11b and 11c for mounting the armrests 12 and 13 are provided on the flat portion except for the peripheral portion 11d. Therefore, the mounting portions 11b and 11c for mounting the armrests 12 and 13 are provided at a position slightly inward from the peripheral portion 11d of the bottom plate 11. There is a tendency for the user's weight to be applied to the armrests 12 and 13 from the inside toward the outside. In this embodiment, the mounting portions 11b and 11c for mounting the armrests 12 and 13 are provided at a position inward from the peripheral portion 11d of the base plate 11. And, the peripheral portion 11d of the bottom plate 11 bulges. Therefore, even when the user's weight is applied to the armrests 12 and 13 from the inside of the bottom plate 11 toward the outside, the bottom plate 11 is not easily deflected.

[0045] <armrests 12 and 13>

[0046] As Figure 1 shown, the armrests 12 and 13 include columns 31, arms 32, and armrest portions 33.

[0047] <column 31>

[0048] The column 31 stands up from the bottom plate 11 upward. In this embodiment, the column 31 includes a base portion 31a and a support column portion 31b. Figure 4 is a perspective view of the base portion 31a of the column 31. Figure 5 is a top view of the armrest 12.

[0049] As Figure 1 shown, the base portion 31a is the portion mounted on the bottom plate 11. In this embodiment, the base portion 31a is composed of a plate-like member. The base portion 31a overlaps the bottom plate 11 and is fastened by bolts 31a1. In this case, the mounting portions 11b and 11c of the bottom plate 11 and the base portions 31a of the columns 31 of the armrests 12 and 13 only need to be fastened from above the bottom plate 11. In this embodiment, nuts are inserted into the mounting holes 11b1 and 11c1 of the mounting portions 11b and 11c. Therefore, the base portion 31a is arranged on the bottom plate 11 and fastened with bolts. Because there is a fastening structure in which the mounting portions 11b and 11c of the bottom plate 11 and the base portions 31a of the columns 31 of the armrests 12 and 13 can be fastened from above the bottom plate 11, it is not necessary to lift the bottom plate 11 having a certain weight for operation, improving the operability and the convenience for the user.

[0050] As Figure 4 shown, ribs 31a2 may be appropriately provided on the base portion 31a. The ribs 31a2 are formed by locally bending the plate-like base portion 31a. The base portion 31a is a substantially rectangular plate. Each side of the base portion 31a is mounted on the bottom plate 11 toward the front, rear, left, and right. As Figure 1As shown, bolts 31a1 are installed at the four corners of the base 31a. As Figure 4 and Figure 5 shown, bolt mounting holes 31a3 for mounting the bolts 31a1 are formed at the four corners of the base 31a. A convex portion that bulges in the left - right direction is formed on the base 31a. This convex portion functions as a rib 31a2. As will be described later, in the present embodiment, the base 31a can be mounted relative to the bottom plate 11 by rotating 180 degrees. In addition, the structure of the base 31a, the mounting structure between the base 31a and the bottom plate 11, the reinforcement structure of the base 31a, etc. are not limited to this embodiment.

[0051] The support column portion 31b is a portion that stands upward from the base 31a. In the present embodiment, the support column portion 31b has a telescopic structure with a variable height. The support column portion 31b includes an outer cylinder 61, an inner cylinder 62, and a bolt 63. Figure 6 is a cross - sectional view of the support column portion 31b. In Figure 6 it shows the cross - section of the portion where the bolt 63 is installed in the support column portion 31b.

[0052] The outer cylinder 61 is installed on the base 31a. As Figure 6 shown, bolt mounting holes 61a are formed on the side circumferential surface of the outer cylinder 61. An internal thread portion 61b is provided in the bolt mounting hole 61a. In the present embodiment, as the internal thread portion 61b, a nut is provided at a matching position in the bolt mounting hole 61a. The nut can be welded to the outer cylinder 61. In the present embodiment, the base 31a can be mounted relative to the bottom plate 11 by rotating 180 degrees. The outer cylinder 61 has bolt mounting holes 61a and internal thread portions 61b at the front and back respectively.

[0053] The inner cylinder 62 is installed inside the outer cylinder 61 and has a structure that can slide up and down relative to the outer cylinder 61. On the inner cylinder 62, bolt insertion holes 62a are intermittently formed in the length direction (refer to Figure 14 ). The inner cylinder 62 can be mounted relative to the outer cylinder 61 with its orientation changed in the front - back direction.

[0054] As Figure 6 shown, the bolt 63 has an external thread portion 63a on its outer circumferential surface and is installed in the internal thread portion 61b provided in the bolt mounting hole 61a. The bolt 63 has a length that extends inside the inner cylinder 62 through the bolt mounting hole 61a of the outer cylinder 61 and the bolt insertion hole 62a of the inner cylinder 62 and abuts against the inner side surface of the inner cylinder 62.

[0055] In this case, when the bolt 63 is screwed into the internal thread portion 61b of the bolt mounting hole 61a of the outer cylinder 61, then as Figure 6As shown in the figure, the front end 63b of the bolt 63 contacts the inner side surface of the inner tube 62, pressing the inner tube 62 against the outer tube 61. As a result, the inner tube 62 does not shake relative to the outer tube 61. In addition, the bolt 63 receives a reaction force from the inner tube 62 in the axial direction. Therefore, there is no play between the internal thread portion 61b of the bolt mounting hole 61a and the external thread portion 63a of the bolt 63, and frictional force acts. Therefore, the bolt 63 is not easy to loosen.

[0056] In this embodiment, if Figure 6 As shown, the bolt 63 is provided with an external threaded portion 63a at the end portion mounted on the internal threaded portion 61b. In addition, the portion that is closer to the front end side than the external threaded portion 63a and extends inside the inner tube 62 through the bolt mounting hole 61a is smaller than the inner diameter of the internal threaded portion 61b. Therefore, the front end side of the bolt 63 can be smoothly inserted into the inner tube 62 through the internal threaded portion 61b until the portion provided with the external threaded portion 63a. Therefore, it is easy to install and remove the bolt 63. In addition, in the present embodiment, the bolt 63 is also provided with a knob 63c at the end portion provided with the external threaded portion 63a. Therefore, even without tools, the bolt 63 can be operated by operating the knob 63c.

[0057] By adjusting the height of the support column 31b in this way, the armrests 12 and 13 can be adjusted to an appropriate height. The left and right armrests 12 and 13 can be adjusted to different heights. Figure 1 In the embodiment shown, bolts 63 for adjusting the height of the support 31b are installed at two locations, one above and one below the support 31b. If the height of the support 31b can be maintained by one bolt 63, the bolt 63 may be installed at one location, above and below the support 31b.

[0058] In this embodiment, the support column 31b is offset to one side from the center in the left-right width direction relative to the substantially rectangular base portion 31a. Figure 1 In the illustrated embodiment, the base 31a of the left handrail 12 is mounted on the bottom plate 11 in such a manner that the support column 31b is arranged on the outside of the bottom plate 11. The base 31a of the right handrail 13 is mounted on the bottom plate 11 in such a manner that the support column 31b is arranged on the inside of the bottom plate 11. That is, the left handrail 12 is mounted on the bottom plate 11 in such a manner that the base 31a is rotated 180 degrees with respect to the right handrail 13.

[0059] Further, on the bottom plate 11, six mounting holes 11b1 and 11c1 are provided on each of the left and right sides. The six mounting holes 11b1 and 11c1 of the bottom plate 11 are arranged such that the base portion 31a is mounted on the bottom plate 11 with a stagger in the front and rear directions. In the present embodiment, the armrests 12 and 13 can be adjusted and arranged in the front and rear directions respectively on the left and right sides of the bottom plate 11, and the base portion 31a is rotated 180 degrees and mounted on the bottom plate 11, so that the inner and outer configurations can be selected. Therefore, for example, the armrests 12 and 13 can be arranged at positions where the user can easily use them. In addition, the armrests 12 and 13 can be arranged to avoid the toilet paper holder, the operation panel of the bidet toilet, etc. Therefore, the versatility of the temporary armrest 10 is improved.

[0060] As Figure 6 shown, the support column portion 31b has an oblong shape (elliptical shape). The support column portion 31b is mounted on the base portion 31a in such a manner that the longer width of the oblong is oriented in the front-rear direction and is offset from the center of the base portion 31a in one of the left-right directions. In the present embodiment, a convex portion that bulges along the left-right direction is formed on the base portion 31a as a rib 31a2. The support column portion 31b is mounted on the base portion 31a so as to straddle the convex portion of the base portion 31a that serves as the rib 31a2.

[0061] The base portion 31a can be mounted on the bottom plate 11 by rotating 180 degrees. And by rotating 180 degrees, the support column portion 31b is arranged outside the bottom plate 11 like the left armrest 12, or the support column portion 31b is arranged inside the bottom plate 11 like the right armrest 13. In addition, on the outer cylinder 61 of the support column portion 31b, a bolt mounting hole 61a and an internal thread portion 61b for inserting a bolt 63 therein are provided on the front and rear sides of the outer cylinder 61. In the present embodiment, a bolt insertion hole 62a for inserting the shaft of the bolt 63 is formed on the front side surface of the inner cylinder 62. Regarding the base portion 31a, when it is mounted by rotating 180 degrees with respect to the bottom plate 11, the inner cylinder 62 is mounted on the outer cylinder 61 with the front side surface of the inner cylinder 62 facing forward. And the bolt 63 is installed in the bolt mounting hole 61a and the internal thread portion 61b on the front side of the outer cylinder 61 to adjust the height of the support column portion 31b.

[0062] In the present embodiment, as Figure 2 shown, the base portion 31a can be mounted on the bottom plate 11 by rotating 180 degrees. The outer cylinder 61 is provided with a bolt mounting hole 61a and an internal thread portion 61b at the front and rear respectively. The inner cylinder 62 is an elliptical shape that is slightly smaller than the inside of the outer cylinder 61 which is oblong and longer in the front-rear direction. The inner cylinder 62 can be mounted by rotating 180 degrees with respect to the outer cylinder 61 to change the direction. Therefore, even when the base is rotated 180 degrees, the bolt 63 can be installed from the front of the outer cylinder 61 and the inner cylinder 62 can be fixed from the front.

[0063] In the present embodiment, the support column portion 31b is oblong (elliptical in shape), and the side surface of the support column portion 31b is flat inside the bottom plate 11. Even when the user's leg contacts the inner side surface of the support column portion 31b, it contacts with a relatively large area. Therefore, the pressure feeling when the user's leg abuts against the inner side of the support column portion 31b can be reduced. In addition, the bolt 63 is installed on the front side of the support column portion 31b. The temporary armrest 10 is disposed in front of the toilet 100. Sometimes, the space for arranging the toilet seat of the toilet 100 is limited in the lateral width. In addition, an operation portion of the cleaning device or a toilet paper holder is provided beside the toilet 100. As Figure 1 shown, the bolt 63 of the temporary armrest 10 can always be operated from the front side of the support column portion 31b. Therefore, the operability of the bolt 63 when changing the height of the support column portion 31b is improved.

[0064] In addition, in the present embodiment, the outer contour shape of the support column portion 31b is an oblong shape. As long as there is no particular limitation, the cross-sectional shape of the support column portion 31b is not limited to this manner. The support column portion 31b only needs to have the required rigidity, and the cross-sectional shape of the support column portion 31b can be, for example, a rectangle. Considering the designability, the cross-sectional shape of the support column portion 31b can take various shapes. From this viewpoint, the cross-sectional shape of the support column portion 31b can be, for example, a square or a circle. In addition, as a structure for adjusting the height of the support column portion 31b, a structure in which the inner cylinder 62 is fixed to the outer cylinder 61 of the support column portion 31b is illustrated. As long as there is no particular mention, the structure for adjusting the height of the support column portion 31b is not limited to this manner.

[0065] <Arm 32>

[0066] The arm 32 is provided at the upper end portion of the column 31. The arm 32 extends upward and obliquely rearward from the upper end portion of the support column portion 31b. Figure 7 is a perspective view of the arm 32. In Figure 7 is shown a view of observing the arm 32 and the armrest portion 33 from the obliquely lower rear side. Figure 8 is a rear view of the arm 32 and the armrest portion 33. In the present embodiment, as Figure 1 shown, the arms 32 are respectively installed at the upper ends of the inner cylinders 62 of the support column portion 31b. The arm 32 is a member formed by bending a plate into a predetermined shape so as to form an upper surface 32a and left and right side surfaces 32b, 32c. The lower end of the arm 32 is installed at the upper end of the column 31. In the present embodiment, the arm 32 extends upward and obliquely rearward from the upper end portion of the column 31. The lower end portion of the arm 32 is installed at the upper end of the inner cylinder 62 of the support column portion 31b. In the present embodiment, the lower end portion of the arm 32 is welded to the upper end of the inner cylinder 62 of the support column portion 31b. A cover 34 is installed at the lower end portion of the arm 32. In the present embodiment, the arm 32 is formed of a plate-like member, achieving weight reduction and cost reduction.

[0067] A rotating shaft 35 is installed at the upper end of the column 31 (the upper end of the arm 32 in this embodiment), and the armrest portion 33 is installed on this rotating shaft 35. In other words, the rotating shaft 35 for installing the armrest portion 33 is provided at the rear end of the arm 32. The rotating shaft 35 is an axis extending in the left-right direction. In this embodiment, the rotating shaft 35 penetrates the left and right side surfaces of the arm 32. The rotating shaft 35 of the armrest portion 33 is provided at the upper end of the arm 32 that extends upward and obliquely rearward from the upper end of the column portion 31b. Therefore, the rotation fulcrum of the armrest portion 33 can be set on the rear side with respect to the column 31. In other words, the rotation fulcrum of the armrest portion 33 can be set at a position close to the seat surface of the toilet 100. That is, in this embodiment, a bottom plate 11 is provided in front of the toilet 100, and the column 31 is provided at a position away from the front edge of the bottom plate 11. Nevertheless, the rotation fulcrum of the armrest portion 33 is set at a position close to the seat surface of the toilet 100. Therefore, the armrest portion 33 can be arranged close to the toilet.

[0068] <Armrest portion 33>

[0069] The armrest portion 33 is rotatably installed on the rotating shaft 35 provided on the arm 32. In this embodiment, as Figure 7 and Figure 8 shown, the armrest portion 33 includes a skeleton 33a and an armrest member 33b. In this embodiment, the skeleton 33a is a member formed by bending a plate cut into a predetermined shape. The skeleton 33a includes an upper surface 33a1 and left and right side surfaces 33a2, 33a3 that cover the upper surface and the outer sides of the left and right side surfaces of the arm 32. The rotating shaft 35 provided on the arm 32 penetrates the left and right side surfaces of the skeleton 33a, and supports the skeleton 33a so that it can rotate. The armrest member 33b is installed on the upper surface of the skeleton 33a. The armrest member 33b is arranged on the upper surface of the skeleton 33a and is installed using screws 37. This armrest portion 33 can be used as an armrest and an elbow rest. Therefore, the armrest portion 33 can also be called an elbow rest portion. The armrest member 33b can be made of a material with a good touch for the skin. The armrest member 33b can be made of wood or resin, for example.

[0070] Figure 9 And Figure 10 are respectively side views of the temporary armrest 10. In Figure 9 , a state where the armrest portion 33 is rotated upward by about 45 degrees is shown. In Figure 10 , a state where the armrest portion 33 is rotated upward by about 100 degrees is shown.

[0071] In this embodiment, the armrest portion 33 rotates around the rotating shaft 35 as a base point. The armrest portion 33 can take a first posture extending forward as shown in Figure 1 and a posture as shown in Figure 10A second posture extending upward as shown. Figure 9 An intermediate posture when the armrest portion 33 is rotated is shown. The armrest portion 33 can be supported by the arm 32 in this first posture and the second posture. In this posture, the armrest portion 33 is configured such that rotation is restricted and it is supported. In addition, it can also be configured to be able to take not only the first posture and the second posture, but also multiple postures. Further, the armrest portion 33 can be configured to be able to stop rotating at an arbitrary angle.

[0072] The armrest portion 33 can be provided with a locking structure for maintaining rotation in a first posture extending forward. Additionally, the armrest portion 33 can also be provided with a locking structure for maintaining rotation in a second posture extending upward. Here, the locking structure can include a locking plate 36 that penetrates the left and right side surfaces 33a2, 33a3 of the skeleton 33a. The locking plate 36 abuts against the left and right side surfaces 32b, 32c of the arm 32 to restrict the rotation of the skeleton 33a of the armrest portion 33. In the present embodiment, the locking plate 36 is composed of a plate-shaped member. The plate-shaped member has good visibility, and the locked situation is clear at a glance. In addition, the locking structure is not limited to this method. For example, the locking plate 36 can also be a shaft-shaped member instead of a plate-shaped one. Also, the rotating shaft 35 can be a ratchet type and configured to stop rotating at a specified rotation angle. In this way, the locking structure can adopt a known method.

[0073] In contrast, according to Figure 1 For the temporary armrest 10 shown, the arm 32 extends upward and obliquely rearward from the upper end portion of the column 31 that stands upright from the bottom plate 11. And the armrest portion 33 is installed so as to be rotatable about a rotating shaft 35 provided at the upper end portion of the arm 32. The rotating shaft 35 is arranged along the left-right direction. The armrest portion 33 rotates upward from the upper end portion of the arm 32 toward the rear. In this temporary armrest 10, the arm 32 extends upward and obliquely rearward from the upper end portion of the column 31. Therefore, as Figure 10 shown, when the armrest portion 33 is lifted upward, the armrest portion 33 becomes a state of extending upward from the rear end portion of the arm 32. In other words, the armrest portion 33 is located further rearward on the side of the toilet 100.

[0074] In addition, the arm 32 extends upward and obliquely rearward from the upper end portion of the column 31 that stands upright from the bottom plate 11. And the armrest portion 33 is installed so as to be rotatable about a rotating shaft 35 provided at the upper end portion of the arm 32. Therefore, the overlapping portion of the armrest portion 33 and the arm 32 is also small. Thus, the cover provided on the side of the armrest portion 33 can be small. For example, in the present embodiment, as Figure 7 and Figure 8As shown, the left and right side surfaces 33a2 and 33a3 of the skeleton 33a of the armrest portion 33 extend downward to cover the portion where the armrest portion 33 overlaps with the arm 32, but this portion can be relatively small. These left and right side surfaces 33a2 and 33a3 prevent the fingers from being pinched at the portion where the armrest portion 33 overlaps with the arm 32. In addition, from this perspective, a cover for preventing the fingers from being pinched at the portion where the armrest portion 33 overlaps with the arm 32 can also be provided using a component different from the armrest portion 33.

[0075] When the armrest portion 33 rotates upward, an open space is formed above the column 31. Therefore, in the case of need for care, the operability of the caregiver is improved. In addition, for a user who does not need the support of the armrest portion 33, rotating the armrest portion 33 upward can make the armrest portion 33 less obstructive. In this way, in Figure 1 In the temporary armrest 10 shown, for a caregiver or a user of the toilet 100 who does not need the armrest portion 33, the armrest portion 33 is less obstructive. Therefore, by adopting the temporary armrest 10, the convenience of the user is improved.

[0076] In addition, the rotating shaft 35 is provided at the upper end portion of the arm 32. The rotating shaft 35 is provided at the rear side (a position approximately near the rear end) of the armrest portion 33. Therefore, the armrest portion 33 can be lifted significantly by raising the front end. In addition, when viewed from above, the column 31 is located at the middle portion of the armrest portion 33. The arm 32 extends upward and obliquely rearward from the upper end portion of the column 31, so the rotation fulcrum of the armrest portion 33 is provided at the rear end portion of the armrest portion 33. Therefore, even when the user applies body weight at a position behind the rotation fulcrum of the armrest portion 33, the armrest portion 33 is not likely to rotate accidentally. In addition, a locking structure is also provided on the armrest portion 33 to prevent the armrest portion 33 from rotating backward accidentally.

[0077] In addition, in the present embodiment, the rotating shaft 35 extends along the left - right direction. In this case, when the armrest portion 33 moves in the front - rear direction, the movable area of the armrest portion 33 does not expand in the left - right direction. Therefore, the temporary armrest 10 is easy to be arranged in a space - saving manner. In addition, without special mention, the rotating shaft 35 does not need to be completely arranged along the left - right direction and can be inclined with respect to the left - right direction. For example, when allowing the movable area of the armrest portion 33 to expand, the rotating shaft 35 can be inclined with respect to the left - right direction.

[0078] Figure 11 is a longitudinal sectional side view showing a modified example of the temporary armrest 10. As Figure 11 shown, the arm 32 can have a strengthening structure inside. In Figure 11 the manner shown, the bent sheet 41 is installed between the left and right side surfaces 32b and 32c of the arm 32 (refer to Figure 7 and Figure 8)。The plate 41 can be welded to the left and right side surfaces 32b and 32c of the arm 32 respectively. In addition, a pedestal 42 for supporting the base end of the armrest 33 is provided on the upper surface 32a of the arm 32. The upper end 42a of the pedestal 42 is flat and supports the lower surface 33a1 of the skeleton 33a of the armrest 33. The pedestal 42 is provided by a plate material and can be installed so that a part thereof penetrates through the inside of the arm 32. The left and right side surfaces 33a2 and 33a3 of the skeleton 33a of the armrest 33 can cover both sides of the pedestal 42. In addition, in the present embodiment, the rear end portion 42b of the pedestal 42 covers the rear side of the rotation shaft 35. Thereby, it is possible to prevent a finger or the like from entering through the gap on the rear side of the rotation shaft 35 of the arm 32. In this way, a cover can also be provided in the gap on the rear side of the rotation shaft 35 of the arm 32.

[0079] Figure 12 It is a side view showing a modified example of the temporary armrest 10. As Figure 12 shown, a handle 43 can also be installed on the upper part of the column 31 so that it is easy to grasp when placing the hand. The handle 43 can be formed of a soft material such as rubber, for example. The shape of the handle 43 can be changed in various ways.

[0080] Figure 13 and Figure 14 are side views showing modified examples of the column 31 respectively. As Figure 13 shown, the bolt insertion holes 62a formed in the inner cylinder 62 can be set within the following range, that is, within the range of being housed in the outer cylinder 61 within the range where the inner cylinder 62 can be adjusted to move up and down. Thereby, the bolt insertion holes 62a do not protrude outside the outer cylinder 61, so problems such as an object being hooked by the bolt insertion holes 62a do not occur. As Figure 13 shown, for the bolt mounting holes 61a provided in the outer cylinder 61, one can be provided above half of the height of the outer cylinder 61. By setting the bolt mounting holes 61a at a position above half of the height of the outer cylinder 61, a larger sliding amount of the inner cylinder 62 can be obtained. In addition, when the sliding amount is limited so that the bolt insertion holes 62a formed in the inner cylinder 62 do not protrude from the outer cylinder 61, a longer portion of the inner cylinder 62 housed in the outer cylinder 61 can be ensured. Therefore, the shaking can be suppressed to a small level.

[0081] It is not limited to this method, and the bolt mounting holes 61a provided in the outer cylinder 61 can also be set at a position below half of the height of the outer cylinder 61. In addition, as another method, as Figure 14 shown, bolts 63 can also be installed at the upper and lower two places of the outer cylinder 61 of the column 31. Thereby, the inner cylinder 62 is stabilized. In addition, the base portion 31a of the column 31 can be rotatably mounted on the bottom plate 11 by 180 degrees. Therefore, it can be configured such that the inner cylinder 62 can be mounted relative to the outer cylinder 61 by rotating 180 degrees. In the present embodiment, as Figure 1As shown, a mark 62b is provided on the outer side surface of the inner cylinder 62. The mark 62b can be set such that the bolt insertion hole 62a of the inner cylinder 62 is aligned with the bolt mounting hole 61a of the outer cylinder 61 by aligning with the upper end of the outer cylinder 61. The mark 62b can be marked using a notch, a seal, a coating, etc. The mark 62b can be provided, for example, on the outer side surface of the front side of the inner cylinder 62.

[0082] As Figure 1 shown, the handrails 12 and 13 of the temporary handrail 10 include: a base portion 31a that is mounted on the mounting portions 11b and 11c of the bottom plate 11; a support portion 31b that stands up from the base portion 31a; and a handrail portion 33 that is provided at the upper end portion of the support portion 31b. In the present embodiment, an arm 32 is provided at the upper end portion of the support portion 31b, and the handrail portion 33 is provided on the arm 32. As Figure 2 shown, when viewed from above, the handrail portion 33 is provided at a position eccentric with respect to a predetermined center position of the base portion 31a. The base portion 31a and the bottom plate 11 have the following mounting structure: the base portion 31a can be mounted on the bottom plate 11 in a plurality of states, and the plurality of states are formed by rotating with respect to a predetermined mounting center position on the bottom plate 11.

[0083] In the present embodiment, the base portion 31a is mounted on the bottom plate 11 so as to be rotatable 180 degrees. For example, in Figure 2 this case, the handrail portion 33 of the handrail 12 arranged on the left side is located outside the bottom plate 11, in other words, outside the bottom plate 11 with reference to the left base portion 31a. In contrast, the handrail portion 33 of the handrail 13 arranged on the right side is located inside the bottom plate 11, in other words, inside the bottom plate 11 with reference to the right base portion 31a. By rotating the base portion 31a of the handrail 12 arranged on the left side by 180 degrees and mounting it on the bottom plate 11, both handrail portions 33 of the handrails 12 and 13 can be made to be inside. By rotating the base portion 31a of the handrail 13 arranged on the right side by 180 degrees and mounting it on the bottom plate 11, both handrail portions 33 of the handrails 12 and 13 can be made to be outside. In this way, by rotating the base portion 31a by 180 degrees for mounting, the position of the handrail portion 33 with respect to the bottom plate 11 can be changed. In the present embodiment, with respect to the relationship between the bolt mounting holes 31a3 formed in the base portion 31a and the mounting holes 11b1 and 11c1 provided in the bottom plate 11, the center position of the base portion 31a mounted on the bottom plate 11 is determined. In this way, the mounting center position of the base portion 31a on the bottom plate 11 can be determined by the mounting structure of the bottom plate 11 and the base portion 31a.

[0084] Figure 15 and Figure 16These are respectively top views showing modified examples of the arm 32. The arm 32 can extend upward and obliquely rearward from the upper end portion of the column 31 at the upper end portion of the support column portion 31b. For example, as Figure 1 shown, the arm 32 can also extend straight rearward from the upper end portion of the support column portion 31b. Additionally, as Figure 15 or Figure 16 shown, the arm 32 can also extend obliquely rearward in the left - right direction from the upper end portion of the support column portion 31b. When the arm 32 extends obliquely in the left - right direction from the upper end portion of the support column portion 31b and extends rearward, for example, the arm 32 can be installed by rotating 180 degrees relative to the upper end portion of the support column portion 31b. The base portion 31a of the column 31 can be rotatably installed on the bottom plate 11 by 180 degrees. Correspondingly, by appropriately rotating the arm 32 by 180 degrees, as Figure 15 and Figure 16 shown, the position where the armrest portion 33 is provided inside or outside the column 31 can be adjusted. In this way, at the upper end portion of the column 31, the extending direction of the arm 32 can be changed. In this case, the arm 32 can also be installed at the upper end portion of the column 31 via a universal joint that can change the orientation in the rotational direction and the up - down direction. A universal joint that can change the orientation in the rotational direction and the up - down direction can apply a known hinge structure.

[0085] Furthermore, in the above - mentioned embodiment, the arm 32 is provided at the upper end portion of the column 31, and the armrest portion 33 is installed at the upper end portion of the arm 32. The temporary armrest is not limited to this method. For example, it can also be that there is no arm 32 at the upper end portion of the column 31. Additionally, in the above - mentioned embodiment, the armrest portion 33 can take a first posture extending forward and a second posture extending upward at the upper end portion of the column 31. That is, the armrest portion 33 is installed on the rotating shaft 35 provided at the upper end portion of the column 31, and the armrest portion 33 can be raised rearward. The temporary armrest disclosed herein is not limited to this method. It can also be that the armrest portion 33 is fixed to the upper end portion of the column 31. In this case, although the armrest portion 33 cannot be raised, the temporary armrest can be constructed inexpensively. Additionally, when the armrest portion 33 is directly installed at the upper end portion of the column 31 without providing the arm 32, it can also be constructed inexpensively.

[0086] Figure 17 This is a side view showing modified examples of the column 31 and the armrest portion 33. In Figure 17 it shows an armrest 12 where there is no arm 32 at the upper end portion of the column 31 and the armrest portion 33 is directly fixed to the upper end portion of the column 31. In Figure 17In the manner shown, the armrest portion 33 includes a support member 33c and an armrest 33d. The support member 33c is a metallic bracket and has the required mechanical strength. In the present embodiment, the support member 33c is a long sheet-like member. The middle portion 33c1 in the length direction is welded to the upper end portion of the column 31. The support member 33c is bent downward on both sides in the width direction, for example. In the welded portion 33c1 of the support member 33c welded to the upper end portion of the column 31, the upper end portion of the column 31 is clamped by the two sides bent downward in the width direction, and the two sides in the width direction are respectively welded to the upper end portion of the column 31. The armrest 33d can be fixed to the upper side of the support member 33c by screws.

[0087] In addition, in Figure 17 the manner shown, the column 31 includes an outer cylinder 61 and an inner cylinder 62 and is configured to be height-adjustable by bolts 63. The mounting structure of the bolts 63 is as described above. In addition, although the column 31 is configured to be height-adjustable, it may also be a structure that cannot be height-adjusted. In this case, the column 31 may also be a hollow shaft member and have a predetermined required length. Thus, in the temporary armrest 10 disclosed herein, the column 31 may also be a column that cannot be height-adjusted without special mention.

[0088] In addition, in Figure 1 the manner shown, the base portion 31a of the column 31 is plate-shaped and has bolt mounting holes 31a3 (see Figure 4 ). The bottom plate 11 has mounting holes 11b1, 11c1 corresponding to the bolt mounting holes 31a3 of the base portion 31a (see Figure 3 ). Nuts are provided in the mounting holes 11b1, 11c1. Therefore, when the column 31 is mounted on the bottom plate 11, the column 31 can be disposed on the bottom plate 11 with the bottom plate 11 set and fixed by bolts. As described above, the base plate 11 of the temporary armrest 10 has the required weight so that it is not easily lifted. When mounting the column 31, it is not necessary to lift the bottom plate 11, so the operability when mounting the column 31 on the bottom plate 11 is significantly improved.

[0089] In Figure 1 the manner shown, the bolt mounting holes 31a3 are formed in the peripheral portion of the base portion 31a. Therefore, the plate shape can be firmly mounted on the bottom plate 11. The base portion 31a has a raised convex portion 31a2. The raised convex portion 31a2 functions as a rib as described above. By providing the convex portion 31a2, the rigidity of the plate-shaped base portion 31a is improved. And the support column portion 31b is mounted so as to straddle the convex portion 31a2 of the base portion 31a.

[0090] The support portion 31b is provided at a position offset from the center in the left - right width direction to one side with respect to the substantially rectangular base portion 31a, and the base portion 31a can be installed by rotating 180 degrees with respect to the bottom plate 11. The position where the column 31 is provided on the base portion 31a is not limited to this method.

[0091] Figure 18 is a perspective view showing the cover 50 covering the base portion 31a. As Figure 18 shown, the temporary handrail 10 may have a cover 50 that covers the base portion 31a around the support portion 31b. In the present embodiment, the cover 50 has an opening 51 through which the support portion 31b is inserted and a slit 52 communicating with the opening 51. In addition, the cover 50 has a shape corresponding to the rib 31a2 provided on the base portion 31a. The opening 51 is elliptical (oblong) to match the shape of the support portion 31b, with a longer width in the front - rear direction and a shorter width in the left - right direction. In addition, the edge 51a of the opening 51 bulges. The slit 52 is formed to reach the peripheral portion from the front ends of the semi - circular portions provided in the front and rear of the opening 51. In addition, the cover 50 is made of resin having required rigidity and flexibility, and ribs for maintaining the shape are appropriately provided on the back surface of the cover 50. For this cover 50, the slit 52 can be expanded within the elastic range. And the support portion 31b can be inserted into the opening 51 from the gap of the expanded slit 52. Therefore, even after the handrail portion 33 is installed on the support portion 31b, the cover 50 can be installed on the base portion 31a or removed therefrom.

[0092] Figure 19 is a top view schematically showing a modified example of the base portion 31a of the column 31. As Figure 19 shown, the base portion 31a may be square and have bolt mounting holes 31a3 provided at the four corners. On the bottom plate 11, mounting holes 11b1, 11c1 may be formed corresponding to the bolt mounting holes 31a3 of the base portion 31a. In this case, the base portion 31a can be installed by rotating 90 degrees with respect to the bottom plate 11. The support portion 31b may be provided at a position offset from the rotation center position of the base portion 31a when installed on the bottom plate 11. In Figure 19 the shown method, the support portion 31b is provided at a position offset diagonally from the rotation center position of the base portion 31a. In this case, even if the position where the base portion 31a is installed on the bottom plate 11 is the same, by rotating the base portion 31a with respect to the bottom plate 11, the position of the support portion 31b with respect to the bottom plate 11 can be adjusted to four kinds. In addition, as Figures 1 to 3 shown in the method, when mounting positions of the base portion 31a are provided at two places offset in the front - rear direction on the left and right sides of the bottom plate 11 respectively, eight positions of the support portion 31b can be prepared on the left and right sides of the bottom plate 11 respectively. Thus, it is easy to finely adjust the position of the support portion 31b with respect to the bottom plate 11 and the position of the handrail portion 33 with respect to the bottom plate 11.

[0093] Thus, regarding the base, in terms of the orientation of installation relative to the bottom plate, it is sufficient to provide two or more at the central position of installation on the bottom plate relative to the base. For example, the base can be triangular, pentagonal, hexagonal, etc., and the illustration is omitted. In addition, the base can also be in the shape of a disc. Moreover, the base can be configured to be installed on the bottom plate in an orientation after multiple rotations according to its shape. Thereby, it is easy to finely adjust the position of the support column portion 31b relative to the bottom plate 11 and the position of the armrest portion 33 relative to the bottom plate 11. Therefore, even in a narrow toilet space, the positions of the support column portion 31b and the armrest portion 33 can be appropriately adjusted according to the user's situation or the equipment.

[0094] Various explanations have been made for one embodiment of the temporary armrest disclosed herein. The temporary armrest disclosed herein is not limited to the above embodiment. In addition, various changes can be made to the temporary armrest disclosed herein. As long as no particular problem occurs, each component or each process described herein can be appropriately omitted or appropriately combined.
