[0009] A handrail device 1, comprising a base body 2 and a handrail body 3 fixed to the base body 2, is used, for example, to assist the movement of a user such as a person requiring care, such as walking. The base body 2 supports the handrail body 3 when placed on the ground or floor, and therefore the base body 2 needs to have a certain amount of weight.

[0010] Therefore, this disclosure provides a handrail device 1 that allows for easy movement of the base body 2, and a base body 2 that can be easily moved.

[0011] Embodiments and modifications will be described with reference to Figures 1 to 7B. Note that the embodiments and modifications described below are only a part of the various embodiments of this disclosure. Furthermore, the embodiments and modifications described below can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. Furthermore, it is possible to combine the configurations of the modified versions as appropriate. The diagrams referenced below are all schematic, and the dimensional ratios of the components in the diagrams do not necessarily reflect the actual dimensional ratios.

[0012] Figures 1 to 6 show a handrail device 1 according to an embodiment. As shown in Figure 1, the handrail device 1 comprises a plate-shaped base body 2 and a handrail body 3 supported by the base body 2. As shown in Figure 2, the base body 2 has a locking portion 6 on its upper surface. As shown in Figure 3, the locking portion 6 has a protruding portion 61 that protrudes in a direction perpendicular to the vertical direction.

[0013] Therefore, when moving the base body 2 which is placed on the floor or ground, a person can easily apply upward force to the base body 2 by placing their fingers on the protruding part 61 of the locking part 6 of the base body 2. As a result, the base body 2 can be easily lifted and moved from the floor or ground.

[0014] In the following, unless otherwise specified, the vertical direction will be defined and the structure of the handrail device 1 will be described based on the state in which the handrail device 1 is in use, that is, the state in which the base body 2 is placed on the floor or ground. Also, unless otherwise specified, in the following description, a plan view refers to looking from above downwards when the handrail device 1 is in use.

[0015] As shown in Figure 1, the handrail device 1 comprises a base body 2 and a handrail body 3 supported by the base body 2.

[0016] As shown in Figures 1 and 2, the base body 2 is a plate-shaped member having a thickness in the vertical direction and has a rectangular shape in plan view. That is, the vertical direction is also the thickness direction of the base body 2. The base body 2 includes a plate body 21, an edge body 23, and a cover body 22 (see Figures 1 to 5).

[0017] The plate body 21 is plate-shaped and rectangular in plan view. The plate body 21 is preferably made of a metal such as stainless steel. The plate body 21 is arranged such that its thickness direction extends along the vertical direction. Two locking portions 6 are formed on the upper surface of the plate body 21. Each locking portion 6 is an opening that opens at the upper surface of the plate body 21. The locking portion 6 penetrates the plate body 21 in the vertical direction, thereby penetrating the base body 2 in the vertical direction. The two locking portions 6 are arranged at intervals along the edge of the plate body 21 (that is, along the edge of the base body 2). Each locking portion 6 has an elongated shape in one direction in plan view; specifically, each locking portion 6 has an elongated shape along the direction in which the locking portions 6 are arranged in plan view. Therefore, for example, a person can lift the base body 2 with the fingers of the right hand and the left hand inserted into one locking portion 6 and the other locking portion 6 respectively and with the fingers hooked on the protruding portion 61, so that the base body 2 can be lifted more easily.

[0018] The length dimension (LA) of the locking portion 6 in plan view is preferably 40 mm or more. In this case, it is easy to insert a plurality of fingers into the locking portion 6. The length dimension (LA) of the locking portion 6 is more preferably 60 mm or more, and still more preferably 80 mm or more. Further, the length dimension (LA) of the locking portion 6 is preferably 200 mm or less. In this case, the dimension of the locking portion 6 does not become excessively large, and can be sufficient for inserting a plurality of fingers into the locking portion 6. The dimension (LA) of the locking portion 6 is more preferably 150 mm or less.

[0019] It is preferable that the width dimension (LB) of the engaging portion 6 in a plan view, that is, the dimension in the direction orthogonal to the length direction of the engaging portion 6 in a plan view, is 15 mm or more. In this case, it is easy to insert a finger into the engaging portion 6. The width dimension (LB) of the engaging portion 6 is more preferably 20 mm or more, and still more preferably 25 mm or more. Further, the width dimension (LB) of the engaging portion 6 is preferably 50 mm or less. In this case, the dimension of the engaging portion 6 does not become excessively large, and the engaging portion 6 can have a dimension sufficient for inserting a finger thereinto. The width dimension (LB) of the engaging portion 6 is more preferably 45 mm or less, and still more preferably 40 mm or less.

[0020] As shown in FIG. 3, a chamfered inclined surface 63 is formed at an upper end portion of an inner peripheral surface 60 of the engaging portion 6, and a chamfered inclined surface 62 is also formed at a lower end portion thereof. Each of the inclined surfaces 62 and 63 may be planar as shown in FIG. 3 or may be curved. As a result, a protruding portion 61 protruding toward the inside of the engaging portion 6 is formed on the inner peripheral surface 60 of the engaging portion 6. The protruding portion 61 is preferably formed so as to protrude toward the inside of the engaging portion 6 from the position of the lower end of the inner peripheral surface 60 as described above. In this case, it is particularly easy to hook a finger on the protruding portion 61. A protruding dimension L1 of the protruding portion 61 toward the inside of the engaging portion 6 with respect to the position of the lower end of the inner peripheral surface 60 is preferably 1 mm or more and 6 mm or less.

[0021] The plate body 21 includes a fixing hole 24 opened at an upper surface thereof. A plurality of (four in the illustrated example) fixing holes 24 constitute one fixing hole group 25. The plate body 21 includes the same number of fixing hole groups 25 as the number of engaging portions 6, that is, the plate body 21 includes two fixing hole groups 25. The engaging portions 6 and the fixing hole groups 25 are associated with each other in a one-to-one manner, and the fixing holes 24 of the fixing hole group 25 are arranged so as to surround the engaging portion 6 corresponding to the fixing hole group 25.

[0022] The edge 23 is frame-shaped and is attached to the periphery of the plate body 21, surrounding this periphery. The edge 23 is made of rubber, for example, but is not limited to this. The upper surface of the edge 23 slopes gently downwards towards the outside (opposite side from the plate body 21). Therefore, the possibility of a user tripping over the periphery 111 of the base body 2 when walking is reduced.

[0023] The cover body 22 is plate-shaped with thickness in the vertical direction and rectangular in plan view. The cover body 22 is made of, for example, synthetic resin, but is not limited to this. The cover body 22 is superimposed on the upper surface of the plate body 21. The cover body 22 has openings that expose a part of the upper surface of the plate body 21 to the outside. The openings are notches or holes, as shown in Figures 2 and 4, for example. The same number of openings as the number of locking parts 6 are formed, and there is a one-to-one correspondence between the openings and the locking parts 6. The openings expose the locking parts 6 and the group of fixing holes 25 corresponding to the locking parts 6 to the outside. For this reason, the openings form recesses on the upper surface of the base body 2 that open upward, and the locking parts 6 corresponding to the openings and the fixing holes 24 of the group of fixing holes 25 corresponding to the locking parts 6 are open at the bottom surface of each recess.

[0024] The handrail body 3 comprises one or more (two in the illustrated example) support posts 31 projecting upward from the base body 2, and a handrail 32.

[0025] The number of support columns 31 is the same as the number of locking parts 6 (two in the illustrated example). Each support column 31 comprises a first support column 311 and a second support column 312 that protrudes upward from the first support column 311. The lower end of the first support column 311 is fixed onto the base body 2. The second support column 312 is supported by the first support column 311 in a height-adjustable manner relative to the first support column 311.

[0026] The handrail 32 is supported by two support posts 31 such that it spans from the upper end of one post to the upper end of the other. The handrail 32 comprises two vertical bars 321 that are elongated vertically and a horizontal bar 322 formed to span between the two vertical bars 321. In the illustrated example, the handrail 32 comprises three horizontal bars 322, which are spaced apart vertically.

[0027] The support column 31 is equipped with a fixing bracket 35 at its lower end, i.e., the lower end of the first support column 311. The fixing bracket 35 is plate-shaped with thickness in the vertical direction, fits within the exposed portion, and has a plan view dimension larger than that of the locking portion 6. The fixing bracket 35 is equipped with fixing holes 351 corresponding to each of the fixing holes 24 included in a group of fixing holes 25.

[0028] Each support column 31 is also equipped with a metal fitting cover 34. The metal fitting cover 34 has vertical insertion holes. As shown in Figures 4 to 6, when the first support column 311 is inserted through the insertion holes, the metal fitting cover 34 is movable vertically relative to the support column 31. The metal fitting cover 34 has a shape and dimensions such that it can cover the entire fixing fitting 35 from above.

[0029] As shown in Figure 6, each support post 31 of the handrail body 3 is positioned such that the fixing bracket 35 is on the base body 2, the fixing bracket 35 covers one locking portion 6, and the fixing hole 351 of the fixing bracket 35 is aligned with the corresponding fixing hole 24 of the base body 2. Therefore, the locking portion 6 is covered at the lower end of the support post 31. In this state, the fixing bracket 35 is fixed to the base body 2 by passing fasteners such as screws, bolts, or other fasteners through the fixing hole 351 of the fixing bracket 35 and the fixing hole 24 of the base body 2. As a result, the support posts 31 are fixed to the base body 2 so as to protrude upward from the base body 2, and the handrail body 3 is supported by the base body 2. With the fixing bracket 35 fixed to the base body 2, when each fitting cover 34 is moved downward and positioned at the lower end of the support post 31, each fitting cover 34 covers the fixing bracket 35 as shown in Figure 1.

[0030] In this embodiment, as described above, the handrail body 3 can be attached to the base body 2 using fasteners, and the handrail body 3 can be separated from the base body 2 by removing the fasteners. In other words, the handrail body 3 can be attached to and detached from the base body 2 non-destructively. For this reason, when using the handrail device 1, the handrail body 3 can be attached to the base body 2 and the handrail device 1 can be used. Furthermore, when transporting or storing the handrail device 1, the handrail body 3 can be separated from the base body 2 to reduce the bulkiness of the handrail device 1 and improve convenience.

[0031] In this embodiment, when the handrail body 3 is separated from the base body 2 and the base body 2 is moved from the floor or ground, as described above, a person can easily apply upward force to the base body 2 by inserting their fingers into the locking portion 6 of the base body 2 and then placing their fingers on the protruding portion 61. Therefore, the base body 2 can be easily lifted and moved from the floor or ground. Furthermore, when the handrail body 3 is attached to the base body 2, such as when using the handrail device 1, the locking portion 6 of the base body 2 is covered by the lower end of the support column 31 of the handrail body 3 and does not appear to the outside, as shown in Figure 1. Therefore, when a user walks on the base body 2, they will not trip over the locking portion 6, thus increasing user safety.

[0032] Modifications are described below. The modifications described below can be applied in appropriate combination with the above embodiments.

[0033] In this embodiment, the locking portion 6 is an opening that opens on the upper surface of the base body 2, but the locking portion 6 does not have to be an opening. For example, the locking portion 6 may be a protrusion that projects upward from the upper surface of the base body 2, and a projection 61 may protrude from this protrusion. Also, if the locking portion 6 is an opening that opens on the upper surface of the base body 2, the locking portion 6 may be a recess that opens on the upper surface of the base body 2.

[0034] In this embodiment, the protrusion 61 is formed around the entire circumference of the inner circumferential surface 60 of the locking portion 6, but the protrusion 61 may be formed only on a part of the inner circumferential surface 60. It is preferable that the protrusion 61 be formed at a position on the inner circumferential surface 60 where fingers can easily grip it.

[0035] In this embodiment, a protrusion 61 is formed on the inner circumferential surface 60 of the locking portion 6 by forming chamfered inclined surfaces 63 and 62 at the upper and lower ends, respectively. However, for example, the protrusion 61 may be formed by not forming an inclined surface 63 at the upper end of the inner circumferential surface 60 of the locking portion 6, but only forming an inclined surface 62 at the lower end. Alternatively, instead of an inclined surface 62, a circumferential groove may be formed around the entire circumference of the inner circumferential surface 60 at the lower end of the inner circumferential surface 60, and the protrusion 61 may be formed above this groove.

[0036] In this embodiment, the locking portion 6 is covered by the lower end of the support post 31 of the handrail body 3, but the locking portion 6 does not have to be covered by the lower end of the support post 31. That is, the support post 31 may be fixed to the base body 2 at a position different from the position of the locking portion 6. In that case, when the handrail device 1 is in use, the locking portion 6 may be exposed on the upper surface of the base body 2 and may be covered by means other than the support post 31.

[0037] In this embodiment, there are two locking parts 6, but there is no limit to the number of locking parts 6; there may be one locking part 6 or three or more.

[0038] In this embodiment, the number of locking parts 6 and the number of support columns 31 are the same, but the number of locking parts 6 may be greater than the number of support columns 31, or the number of support columns 31 may be greater than the number of locking parts 6. If the number of locking parts 6 is greater than the number of support columns 31, the locking parts 6 may include at least one locking part 6 that is covered by the lower end of the support column 31 and at least one locking part 6 that is not covered by the lower end of the support column 31. Also, if the number of support columns 31 is greater than the number of locking parts 6, the support columns 31 may include at least one support column 31 that covers the locking part 6 at its lower end and at least one support column 31 that does not cover the locking part 6 at its lower end.

[0039] In this embodiment, one handrail body 3 is provided with two support posts 31, but there is no limit to the number of support posts 31 that one handrail body 3 may have; the number of support posts 31 may be one or three or more.

[0040] In this embodiment, one handrail body 3 is supported by one base body 2, but two or more handrail bodies 3 may be supported by one base body 2.

[0041] In this embodiment, one handrail body 3 is supported by only one base body 2, but one handrail body 3 may be supported by multiple base bodies 2. That is, the handrail device 1 may have multiple base bodies 2, and the support column 31 of the handrail body 3 may be fixed to each base body 2.

[0042] In this embodiment, the handrail body 3 is detachable from the base body 2, but the handrail body 3 does not necessarily have to be detachable from the base body 2. That is, it is not necessary for the handrail body 3 and the base body 2 to be separated without destruction. In this case, if the locking portion 6 is exposed on the upper surface of the base body 2 and not covered by the lower end of the support column 31, the base body 2 can be lifted using the locking portion 6 while the handrail body 3 is supported on the base body 2, and the base body 2 can be moved together with the handrail body 3. Also, even if the locking portion 6 is covered by the lower end of the support column 31, the base body 2 can be moved using the locking portion 6 before the handrail body 3 is attached to the base body 2.

[0043] The structure of the base body 2 in the embodiment is an example; for example, the base body 2 does not have to include a cover body 22, nor does it have to include an edge body 23. The base body 2 may consist only of a plate body 21.

[0044] The structure of the handrail body 3 in the embodiment is just one example, and for example, the shape of the handrail 32 may differ from that of the embodiment. Also, in the embodiment, the support column 31 and the handrail 32 are different members, but the support column 31 and the handrail 32 may constitute a single, inseparably integrated member.

[0045] There are no restrictions on the structure for supporting the handrail body 3 on the base body 2. For example, the handrail body 3 may be fixed to the base body 2 by means of welding or adhesive, or the base body 2 and the handrail body 3 may each be provided with interlocking parts, and the handrail body 3 may be fixed to the base body 2 by interlocking the base body 2 and the handrail body 3.

[0046] Furthermore, when moving the base body 2, an auxiliary device 7 can be attached to the base body 2, and this auxiliary device 7 can be used to make the base body 2 even easier to move. The auxiliary device 7 and examples of its use are shown in Figures 7A and 7B.

[0047] The illustrated auxiliary device 7 comprises a handle portion 71 and a fixing portion 72. The handle portion 71 is ring-shaped with a hole, through which a person's fingers can be inserted. The fixing portion 72 is a male screw protruding from the handle portion 71, with a male screw groove on its outer surface. The auxiliary device 7 can be attached to the base body 2 by screwing the fixing portion 72 of the auxiliary device 7 into the fixing hole 24 of the base body 2. In this state, a person can apply force to the base body 2 by placing their fingers on the handle portion 71 of the auxiliary device 7. This allows the base body 2 to be easily moved. The number of auxiliary devices 7 attached to the base body 2 is not limited to just one; for example, auxiliary devices 7 can be attached to any position and number of fixing holes 24 in the base body 2.
