Description

[Technical Field]

[0001] The present invention relates to a handrail device to be installed at a step portion. [Background technology]

[0002] Known handrail devices that are installed at step portions include those shown in Patent Documents 1 to 3, for example.

[0003] The handrail device shown in Patent Document 1 is installed at the step between the dirt floor and the frame of the entrance hall, and supports the movement of people moving between the dirt floor and the top surface of the frame. The handrail portion is an inclined body that slopes upward from the dirt floor side, which is the lower surface, to the top surface of the frame, which is the higher surface.

[0004] The handrail device shown in Patent Document 2 is installed at the step between the entrance floor and the top surface of the frame, and supports the actions of pedestrians moving on the walking surface installed between the entrance floor and the top surface of the frame. The handrail portion that the pedestrian holds on to is an inclined body that slopes upward from the lower surface, the floor side, to the higher surface, the top surface of the frame.

[0005] The handrail device shown in Patent Document 3 is installed across the lower and upper steps of a multi-step staircase to support the movement of pedestrians moving up the multi-step staircase, and the handrail portion that the pedestrian holds on to is an inclined body that slopes upward from the lower step to the higher step. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-89974 [Patent Document 2] Japanese Patent Application Laid-Open No. 2016-94759 [Patent Document 3] Patent Publication No. 2021-17783 Summary of the Invention [Problem to be solved by the invention]

[0007] In each of the handrail devices listed above, the handrail portion is an inclined body that follows the slope of the step portion, which at first glance seems to be preferable because the change in height of the handrail portion corresponds to the change in height of the handrail portion when the pedestrian holds onto it. However, in reality, if the handrail portion is inclined, the hands tend to slip when holding onto it to move, making it relatively difficult to properly grasp the handrail and move, or to lean one's weight on the handrail portion to maintain posture, leaving room for improvement in terms of safe walking assistance.

[0008] SUMMARY OF THE INVENTION Accordingly, the present invention has been made with an object of providing a handrail device that improves the grip of the handrail portion and enables safe walking assistance. [Means for solving the problem]

[0009] The present invention employs the following configuration as a specific means for solving the above problems.

[0010] In the first invention of the present application, in a handrail device composed of a pair of left and right handrail units installed across the lower surface side and the higher surface side of a step portion, each of the handrail units is , tier The handrail body is attached to a plurality of base bodies arranged at each step of the difference section in a manner that allows height adjustment to a plurality of upright posts, or to a plurality of base bodies arranged on the same plane in a manner that allows height adjustment to a plurality of upright posts, The handrail body is characterized by having an L-shaped handrail section at each of the upper ends on the higher and lower sides, with the upper part of each handrail section extending approximately horizontally or in an arc shape and the vertical sections extending up and down, each functioning as a grip.

[0011] In a second aspect of the present invention, in the handrail device according to the first aspect of the present invention, Of the pair of left and right handrail units, the base body provided with a support post supporting one handrail unit and the base body provided with a support post supporting the other handrail unit are characterized by being integrally configured to be continuous in the direction in which the handrail units are spaced apart. [Effects of the Invention]

[0012] The present invention provides the following effects.

[0013] (a) According to the handrail device of the first invention of the present application, the handrail device is composed of a pair of left and right handrail units installed across the lower surface side and the higher surface side of the step portion. , tier The handrail body is mounted in a manner that allows its height to be adjusted to a plurality of upright posts on a plurality of base bodies arranged at each step of the difference in height, or in a manner that allows its height to be adjusted to a plurality of upright posts on a plurality of base bodies arranged on the same plane, and an L-shaped handrail section is provided at the upper end of the higher side and the upper end of the lower side of the handrail body, and the upper part of each handrail section extends approximately horizontally or in an arc, and the vertical section extends up and down so that each section functions as a gripping section. Therefore, when a person goes up or down the step along the handrail device, by gripping the vertical and upper parts of each handrail section, they can accurately hold the handrail without slipping, maintain their posture and move safely in the direction of the step, and by being able to accurately grip the handrail section, they can also put their weight on the handrail section to prevent swaying sideways, and the synergistic effect of these factors ensures that movement over the step is even safer.

[0014] Furthermore, since each handrail unit is attached to a plurality of posts that are erected on a plurality of base bodies that are respectively arranged on each step of the step section in a manner that allows the height to be adjusted, the height of each handrail of the handrail unit can be set to an appropriate height regardless of the height dimension of the step, and a highly versatile handrail device can be provided under the current situation where step heights are not always constant.

[0015] Furthermore, because the handrail units are attached to a plurality of posts that are respectively erected on a plurality of base bodies that are installed on the same surface in a manner that allows their heights to be adjusted, by installing this handrail device on the same surface and placing a step-forming member of an appropriate height between the pair of left and right handrail units, the handrail device can function as a handrail device installed on a step.As a result, even in places where there is no step, for example, where the front of an opening in a building is a flat road surface, the handrail device can be used as a handrail device installed on a step by installing the handrail device just before the opening in the building and placing step-forming members between the handrail units on the left and right of the handrail device.This means that the range of application of the handrail device can be extended not only to cases where a step exists, but also to cases where no step exists, thereby improving the versatility of the handrail device.

[0016] (b) In addition to the effect described in (a) above, the handrail device according to the second invention of the present application has the following unique effect: That is, in this invention, the base body equipped with a support post that supports one of the pair of left and right handrail units and the base body equipped with a support post that supports the other handrail unit are integrally configured to be continuous in the direction in which the handrail units are spaced apart, which improves the stability of the handrail device when installed and also improves the workability when disassembling and assembling the handrail device.

As shown in Fig. 1, this handrail device Z1 is installed on a step consisting of a lower surface G11 and a higher surface G12, and is equipped with a pair of left and right first handrail units 1 that face each other at a predetermined distance.

[0020] The first handrail unit 1 is a pipe body De-shaped The handrail body 11 includes a first vertical member 21, a second vertical member 23, and a third vertical member 25 that are erected at an appropriate distance in the step direction, an L-shaped first handrail section 22 attached across the upper end of the first vertical member 21 and the upper end of the second vertical member, and an L-shaped second handrail section 24 attached across the upper end of the second vertical member 23 and the upper end of the third vertical member 25.

[0021] The upper portion 22a of the first handrail portion 22 and the upper portion 24a of the second handrail portion 24 function as gripping parts mainly when moving down a step, and are each straight and extend substantially horizontally. The vertical portion 22b of the first handrail portion 22 and the vertical portion 24b of the second handrail portion 24 function as gripping parts mainly when moving up a step, and are each straight and extend vertically.

[0022] The first vertical members 21 of each handrail main body 11 of the pair of left and right first handrail units 1 are supported by columns 7A arranged upright near the left and right ends of the horizontally elongated first base body 4 installed on the lower surface G11 of the step portion in the width direction thereof, so as to be height-adjustable. The second vertical members 23 of each handrail main body 11 are supported by columns 7B arranged upright at both front ends of the horizontally elongated second base body 5 installed on the higher surface G12 of the step portion in the width direction thereof, so as to be height-adjustable. Furthermore, the third vertical members 25 of each handrail main body 11 are supported by columns 7C arranged upright at both rear ends of the second base body 5 in the height-adjustable manner. The handrail device Z1 is ready for use by adjusting the height of the first handrail unit 1 to match the difference in height between the lower surface G11 and the higher surface G12 of the step portion.

[0023] The handrail device Z1 is used when walking over a step, and when moving upward from the lower surface G11 to the higher surface G12, the vertical portion 22b of the first handrail portion 22 of the handrail main body 11 and the vertical portion 24b of the second handrail portion 24 are mainly used as gripping portions, and because these vertical portions 22b, 24b are both straight, when gripping them, the hands are less likely to slip, providing a reliable walking assistance effect.

[0024] On the other hand, when moving downward from the higher surface G12 to the lower surface G11, particularly reliable walking assistance is required to prevent danger, and when moving downward, the upper part 22a of the first handrail part 22 of the handrail main body 11 and the upper part 24a of the second handrail part 24 are mainly used as gripping parts, and because these upper parts 22a and 24a are both straight and extend horizontally, even when gripping the upper parts 22a and 24a in a slightly forward-leaning position, the hands are less likely to slip, providing reliable walking assistance. This ensures safe movement both when moving upward and downward.

[0025] Second Embodiment 3 and 4 show a handrail device Z2 according to a second embodiment of the present invention. As shown in Fig. 3, this handrail device Z2 is installed on a step consisting of a lower surface G21 and a higher surface G22, and is equipped with a pair of second handrail units 2 on the left and right that face each other at a predetermined distance.

[0026] The second handrail unit 2 is a pipe body De-shaped The handrail body 12 includes a first vertical member 31, a second vertical member 33, a third vertical member 35, and a fourth vertical member 37 that are erected at an appropriate distance in the step direction, an L-shaped first handrail section 32 attached to straddle the upper end of the first vertical member 31 and the upper end of the second vertical member 33, an L-shaped second handrail section 34 attached to straddle the upper end of the second vertical member 33 and the upper end of the third vertical member 35, and an L-shaped third handrail section 36 attached to straddle the upper end of the third vertical member 35 and the upper end of the fourth vertical member 37.

[0027] The upper part 32a of the first handrail part 32, the upper part 34a of the second handrail part 34, and the upper part 36a of the third handrail part 36 are parts that function as grips mainly when moving down a step, and are each straight and extend substantially horizontally. Additionally, the vertical part 32b of the first handrail part 32, the vertical part 34b of the second handrail part 34, and the vertical part 36b of the third handrail part 36 function as grips mainly when moving up a step, and are each straight and extend vertically.

[0028] The first vertical member 31 of the handrail main body 12 is supported by a support pillar 8A, which is arranged upright near both the left and right ends of the horizontally elongated first base body 4, which is installed on the lower surface G21 of the step portion in the width direction, and is inserted and supported in a height-adjustable manner.

[0029] The second vertical member 33 of each handrail body 12 is supported in a height-adjustable manner by inserting it into a support pillar 8B which is arranged upright near both the left and right ends of the horizontally elongated second base body 5 which is installed in the width direction on the mid-level surface G22 of the step portion.

[0030] The third vertical member 35 of each handrail body 12 is supported in a height-adjustable manner by inserting it into support posts 8C erected at both front end portions of a horizontally elongated third base body 6 which is installed on the high surface G23 of the step portion in the width direction.

[0031] The fourth vertical members 37 of each handrail body 12 are inserted and supported by support posts 8D erected at both rear end portions of the third base body 6 so as to be adjustable in height.

[0032] Then, by adjusting the height of the second handrail unit 2 to match the height difference between the lower surface G21, the middle surface G22 and the higher surface G23 of the step portion, the handrail device Z2 is put into a usable state.

[0033] The handrail device Z2 is used when walking over a step, and when moving upward from the lower surface G21 to the higher surface G23, the vertical portion 32b of the first handrail portion 32 of the handrail main body 12, the vertical portion 34b of the second handrail portion 34, and the vertical portion 36b of the third handrail portion 36 are mainly used as gripping portions, and because these vertical portions 32b, 34b, 36b are all straight, the hands are less likely to slip when gripping them, providing a reliable walking assistance effect.

[0034] On the other hand, when moving downward from the higher surface G23 to the lower surface G21, particularly reliable walking assistance is required to prevent danger, and when moving downward, the upper part 32a of the first handrail section 32 of the handrail main body 12, the upper part 34a of the second handrail section 34, and the upper part 36a of the third handrail section 36 are mainly used as gripping parts, and because each of these upper parts 32a, 34a, and 36a is straight and extends horizontally, the hands are less likely to slip even when gripping each of the upper parts 32a, 34a, and 36a in a slightly forward-leaning position, providing reliable walking assistance. This ensures safe movement both when moving upward and when moving downward.

[0035] "Third embodiment" Figures 5 and 6 show a handrail device Z3 according to a third embodiment of the present invention. As shown in Figure 5, this handrail device Z3 is installed on a step consisting of a lower surface G31 and a higher surface G32, and is equipped with a pair of left and right third handrail units 3 that face each other at a predetermined distance.

[0036] The third handrail unit 3 comprises a handrail main body 13 formed in the shape of a ladder with uneven steps using a pipe body. This handrail main body 13 comprises a first vertical member 41, a second vertical member 43, and a third vertical member 45 that are erected at an appropriate distance in the step direction, as well as an L-shaped first handrail section 42 attached across the upper end of the first vertical member 41 and the upper end of the second vertical member 43, and an L-shaped second handrail section 44 attached across the upper end of the second vertical member 43 and the upper end of the third vertical member 45.

[0037] The upper part 42a of the first handrail part 42 and the upper part 44a of the second handrail part 44 function as gripping parts mainly when moving down a step, and the upper part 42a of the first handrail part 42 is straight and extends in a substantially horizontal direction, while the upper part 44a of the second handrail part 44 is arc-shaped. Furthermore, the vertical part 42b of the first handrail part 42 and the vertical part 44b of the second handrail part 44 function as gripping parts mainly when moving up a step, and are straight and extend in a substantially vertical direction.

[0038] The first vertical member 41 of each handrail main body 13 of the pair of left and right third handrail units 3 is supported by height-adjustable supports 9A erected near the left and right ends of the horizontally elongated first base body 4 installed on the lower surface G31 of the step portion facing in the width direction. The second vertical member 43 of each handrail main body 13 is supported by height-adjustable supports 9B erected at both front ends of the horizontally elongated second base body 5 installed on the higher surface G32 of the step portion facing in the width direction. Furthermore, the third vertical member 45 of each handrail main body 13 is supported by height-adjustable supports 9C erected at both rear ends of the second base body 5. The handrail device Z3 can be put into use by adjusting the height of the third handrail unit 3 to match the difference in height between the lower surface G31 and the higher surface G32 of the step portion.

[0039] The handrail device Z3 is used when walking over a step, and when moving upward from the lower surface G31 to the higher surface G32, the vertical portion 42b of the first handrail portion 42 and the vertical portion 44b of the second handrail portion 44 of each handrail main body 13 are mainly used as gripping portions, and because these vertical portions 42b, 44b are both straight, the hands are less likely to slip when gripping them, providing a reliable walking assistance effect.

[0040] On the other hand, when moving downward from the higher surface G32 to the lower surface G31, particularly reliable walking assistance is required to prevent danger. During this downward movement, the upper part 42a of the first handrail section 42 and the upper part 44a of the second handrail section 44 of the handrail main body 13 are mainly used as gripping parts. In this case, because the upper part 42a of the first handrail section 42 is straight, it is less likely to slip when gripped, providing reliable walking assistance. In contrast, because the upper part 44a of the second handrail section 44 is arc-shaped, when a person moves from the higher surface G32 side to the handrail device Z3 side, it can be smoothly gripped as the person moves toward the handrail device Z3 side, and can slide smoothly forward as the person moves, providing walking assistance.

[0041] The combined effect of these features is to ensure safe movement both during upward and downward movement.

[0042] "Fourth embodiment" 7 shows a handrail device Z4 according to a fourth embodiment of the present invention. This handrail device Z4 has a similar structure to the handrail device Z1 shown in the first embodiment described above, and here, the same components as those in the handrail device Z1 are given the same reference numerals as those in the handrail device Z1. The specific structure of the handrail device Z4 will be omitted here, and the corresponding explanation in the first embodiment will be used.

[0043] This handrail device Z4 differs from the handrail device Z1 according to the first embodiment in that the handrail device Z1 is installed at an existing step, whereas the handrail device Z4 of this embodiment is installed in a site situation where there is no existing step on the road surface G01, but there is a building floor surface G02 at a predetermined height beyond it, facing the building floor surface G02, just before the building floor surface, to support walking movement between the road surface G01 and the floor surface G02.

[0044] Specifically, the handrail device Z4 is installed on the road surface G01 just before the building floor surface G02. In this case, the first base body 4 and the second base body 5 are both installed on the road surface G01, so the handrail main body 11 of each first handrail unit 1 has its first vertical member 21, first handrail section 22 and second vertical member 23 inserted and supported by the support post 7A provided on the first base body 4 and the support posts 7B and 7C provided on the second base body 5, and the height position of the handrail main body 11 is set according to the height difference between the road surface G01 and the building floor surface G02.

[0045] Thereafter, a step is formed by placing an appropriate step-forming member 14 between the pair of left and right handrail bodies 11 of the handrail device Z4. In this state, the handrail device Z4 is ready for use.

[0046] Therefore, according to this handrail device Z4, even in places where there are no steps, the handrail device Z4 can be installed to provide walking assistance, thereby improving its versatility. [Industrial Applicability]

[0047] The handrail device according to the present invention can be widely used in nursing care settings and the like. [Explanation of symbols]
