Description

  The present invention relates to a handrail device installed in a mounted state, for example, at a position immediately before an ascending ridge of a front door.

  For example, a stepped part such as an ascending ridge in the entrance of a house can pass without any trouble if the person is a healthy person, but the person is an elderly person and the leg strength is weakened. In the case of a person, it is necessary to ensure a safe walking of the person, and a handrail for a step portion has been proposed from such a viewpoint (see, for example, Patent Documents 1 and 2).

  The handrail shown by patent document 1 is a handrail arrange | positioned ranging between entrance soil and an uphill, and is fixedly arrange | positioned both between an entrance soil and an upwell. However, the installation of such a fixed handrail requires renovation of the house and increases the installation cost, and when it is no longer necessary to provide the handrail at a later date, if the handrail is removed, scratches will remain on the trace and damage the aesthetic There was a problem.

  From such a background, a so-called placement-type handrail device as shown in Patent Document 2 has been proposed and is becoming mainstream. This mounting-type handrail device is configured by disposing a handrail body in which handrails are attached to the upper ends of a plurality of columns on both sides of a flat base, and in particular, The support column provided in the foremost part is configured such that its lower end is in contact with and supported by the upper surface of the uplift. By adopting such a configuration, a stable guide function is exhibited in spite of the placement-type handrail device.

  By the way, in such a handrail device for steps, when a person uses this handrail device to move the stepped portion of the entrance by walking, as with walking on stairs, one step up and down one step. It is assumed that the “kick-up walking” is performed. And, if it seems that the step is too large for the person who passes through the step portion, it is proposed to reduce the step size by placing a step with a predetermined height between the entrance soils (patent) Reference 3).

  However, those who need such a handrail device for the stepped portion are not those who normally use “kick-up walking”, but those who are elderly or physically handicapped, etc. In addition, there is a reality that many of these persons have a “sliding leg walking” that moves with a sliding leg as a normal condition. If so, even if the handrail device is installed between the entrance soil, such a person cannot actually use it, which is not preferable from the viewpoint of care welfare. Therefore, improvement measures are desired.

  In view of this, the present invention has been made for the purpose of providing a handrail device that can be adapted to various walking modes.

  In the present invention, the following configuration is adopted as a specific means for solving such a problem.

In the handrail device according to the first invention of the present application, a handrail body including a plurality of support posts and a handrail attached to the upper end of each support post is disposed on either or both of the left and right edges of the base. A handrail unit configured on the lower surface of the stepped portion, and installed in an inclined state between the higher surface of the stepped portion and the base of the handrail unit, and in the installed state, the handrail A slope unit that is restricted from moving downward in the tilt direction by a regulating means provided between the body and the body, and the regulating means is formed horizontally on the surface of the base so as to extend in the width direction. The slope unit includes a plurality of retaining grooves that are latched at the lower end in the inclination direction.

  In the present invention, the following effects can be obtained.

(A) In the handrail device according to the first invention of the present application, a handrail body including a plurality of columns and a handrail rod attached to the upper end of each column on either or both of the left and right edges of the base. And a handrail unit placed on the lower surface of the stepped portion, and installed in an inclined state between the higher surface of the stepped portion and the base of the handrail unit, and its installed state Since it is provided with a slope unit in which the movement downward in the tilt direction is restricted by the restriction means provided between the handrail body,
(A) When a person moves through the stepped portion, the safety during walking movement is ensured by grasping the handrail rod of the handrail unit and moving along the handrail.
(B) Even if the person who moves through the stepped portion is, for example, a person whose legs and hips are weak and can move only by walking with a sliding foot, the stepped portion can be easily and easily passed through the slope unit. It is possible to provide a handrail device that can safely walk and can be adapted to various walking modes.
(C) When a person walks on a slope unit while traveling on a handrail, especially when moving on the slope unit from the lower side to the upper side in the inclined direction, However, since the movement of the slope unit downward in the tilt direction is restricted by the restricting means, safety in use of the slope unit is ensured. The
Etc. are obtained.

In the first aspect of the invention , the restricting means is formed in a lateral manner so as to extend in the width direction on the surface of the base, and a plurality of latching grooves for latching the lower end in the inclination direction of the slope unit. Since it is only necessary to provide the retaining groove only on the base without performing any processing on the slope unit side, the cost can be reduced by reducing the number of work steps when manufacturing the handrail device. Is promoted.

“First Embodiment”
1 and 2 show a handrail device Z1 according to the first embodiment of the present invention. This handrail device Z1 is installed in the entrance soil 52 and supports walking of a person who moves between the entrance soil 52 and the indoor floor surface 53, and includes the handrail unit 1 and the slope unit 4 described below. Configured.

(1) Handrail unit 1
The handrail unit 1 includes a rectangular flat plate-like base 2 and a pair of handrail bodies 3 that are installed on both the left and right sides of the base 2 in a standing state. The handrail body 3 has three columns, that is, a front column 11, a rear column 13 connected to the front column 11 via a horizontal member 15, and an upper end fixed to the horizontal member 15. An intermediate strut 12 connected to the front strut 11 via a cross member 16 is provided, a front portion of a handrail rod 14 is connected to the upper end of the front strut 11, and the upper end of the rear strut 13 is connected to the upper end of the rear strut 13. The rear part of the handrail 14 is connected. The handrail body 3 fixes the intermediate strut 12 and the rear strut 13 to the base 2, while the lower end portion of the front strut 11 is extendable.

(2) Slope unit 4
The slope unit 4 includes a plurality of horizontally long plate-like end plate materials (four in this embodiment), a lower edge plate material 41 having a long wedge-shaped cross section, and a long wedge-shaped cross section. A sheet-like hinge material 46 is attached to the back side of the upper end plate members 42 of the horizontally long strips having a shape in a line, and these are integrated.

  And in the state which this slope unit 4 expand | deployed in flat form as shown in FIG. 3, the end surfaces of each said edge part board | plate material 42 and each edge part board | plate material 41,42 which mutually adjoin each other contact | abut. The plate-like form is maintained facing the load from above, and the original function as a slope can be exhibited.

  On the other hand, in the slope unit 4, the end plate members 42 and the end plate members 41, 42 are connected to each other only by the hinge member 46 on the back side thereof, as shown in FIG. It can wind up with 46 inside.

  Furthermore, in this embodiment, a predetermined number (six in this embodiment) of pin receiving holes 45 are formed at equal pitches on the left and right end faces of each of the above-mentioned joint plate materials 43. A latch pin 44 is selectively inserted into each pin receiving hole 45. In this case, when the latch pin 44 is inserted into the pin receiving hole 45, the tip of the latch pin 44 is inserted. The length is set so that the side extends outward from the end face of the joint plate member 43 by a predetermined length. The “predetermined length” of the latch pin 44 is the extension of the latch pin 44 in a state where the end face of the foot plate member 43 is close to the intermediate strut 12 or the rear strut 13 of the handrail unit 1. The length is such that the portion can be hooked on the front column 11 or the intermediate column 12. The latch pin 44 corresponds to a “regulator” in the claims.

(3) Installation of the handrail device Z1 First, the handrail unit 1 is positioned so that the base 2 is positioned immediately before the uplift 51 and the front column 11 corresponds to the upper surface of the uplift 51. And it installs on the above-mentioned entrance soil 52. And the lower end part of the said front side support | pillar 11 is extended | stretched, this is contact | abutted to the upper surface of the said rising rod 51, and is supported.

  Next, the unfolded slope unit 4 is arranged with the base plate 2 in a state where the end plate member 41 corresponds to the base 2 side and the end plate member 42 corresponds to the uphill 51 side. It is installed between the uphill 51. In this case, as shown in FIG. 1 and FIG. 2, the connecting portion between the end plate member 42 and the adjacent foot plate member 43 corresponds to the front end corner portion 51 a of the ascending rod 51 on the rising rod 51 side. Thus, the relative position of the slope unit 4 with respect to the uphill 51 is set. With this setting, the slope unit 4 is in a state in which the upper end plate member 42 is bent downward at a position corresponding to the front end corner portion 51a and is in contact with the upper surface of the rising rod 51, A person gets in and out of the upper end plate 42 smoothly.

  On the other hand, among the foot plate members 43 of the slope unit 4, the latch pin 44 is inserted into the pin receiving hole 45 provided on the end surface of the foot plate member 43 corresponding to the rear column 13. In this case, the latch pin 44 is located on the front surface of the front column 11 (that is, the side surface on the upward rod 51 side) among the pin receiving holes 45 located closer to the upward rod 51 than the front column 11. The pin receiving hole 45 which adjoins is selected, and the said latch pin 44 is inserted and inserted here. In this way, by selecting the pin receiving hole 45 and inserting the latch pin 44 therein, the latch pin 44 is arranged in the state of being close to the front surface of the front column 11, for example, When the slope unit 4 tries to move closer to the lower end plate member 41, the hook pin 44 is hooked on the front surface of the front column 11, so that the slope unit 4 is more than that. Movement will be restricted. In addition, the said front side support | pillar 11 corresponds to the "stopper body" in a claim here.

  Here, in spite of the selection setting of the pin receiving hole 45, when it seems that the gap between the latch pin 44 and the front surface of the front column 11 is large, the entire handrail unit 1 is moved in the front-rear direction. Finely adjust the installation position to make the gap as small as possible.

  The hook pin 44 is not inserted into only the pin receiving hole 45 of the foot plate member 43 corresponding to the front column 11, but instead, the foot plate member 43 corresponding to the intermediate column 12. Of course, it can also be inserted into the pin receiving hole 45 of this. Further, the foot plate 43 corresponding to the intermediate strut 12 or the rear strut 13 is not always the same, and changes depending on, for example, the height of the uplift 51 from the entrance soil 52.

  In the handrail device Z1 installed in this way, the slope unit 4 is disposed in the center of the handrail unit 1, and the slope unit 4 is installed between the uplift 51 and the base 2. Therefore, a person who walks and moves through the handrail device Z1 holds each handrail rod 14 of the handrail unit 1 and holds the posture thereof, while performing a “kick-up walk” on the slope unit 4, Or it can move safely by "sliding foot walking". That is, since the handrail device Z1 includes the slope unit 4, it is possible to always ensure the safe walking of the person regardless of the walking form of the person who uses the slope unit 4.

  Further, the movement of the slope unit 4 toward the lower end plate member 41 side, that is, the relative movement of the slope unit 4 with respect to the rising rod 51 is ensured by the latching action of the latch pin 44 and the front column 11. Therefore, the slope unit 4 is always maintained in a highly safe and accurate installation state, thereby further improving the safety of walking of the person using the handrail device Z1.

  In this handrail device Z1, it is not necessary to always use the slope unit 4 with the slope unit 4. For example, the slope unit 4 is removed, and a usage pattern intended for “kick-up walking” is adopted. You can also.

“Second Embodiment”
FIG. 5 shows a handrail device Z2 according to the second embodiment of the present invention. The handrail device Z2 has the same basic configuration as that of the handrail device Z1 according to the first embodiment, and is different from the handrail device Z1 according to the first embodiment in the slope. The movement restriction of the unit 4 is performed by the latching action of the latch pin 44 provided on the slope unit 4 side and the rear column 13 on the handrail unit 1 side. In the handrail device Z <b> 2, a plurality of retaining grooves 47 extending in the width direction of the base 2 are formed on the upper surface of the base 2 at predetermined intervals in the front-rear direction of the base 2. The edge 41a of the lower end plate 41 of the slope unit 4 installed on the slope unit 4 is hooked on any one of the hooking grooves 47, so that the lower end plate 41 of the slope unit 4 is moved to the side. It is intended to regulate the movement of.

  By adopting such a configuration, it is a matter of course that the same effect as the handrail device Z1 in the first embodiment can be obtained, but in addition, any processing is performed on the slope unit 4 side. In addition, since the hook groove only needs to be provided in the base 2, a specific effect that cost reduction is promoted by reducing the number of work steps when manufacturing the handrail device Z <b> 2 is obtained.

  Since the configuration and effects other than those described above are the same as those in the case of the first embodiment, the corresponding description is cited and the description thereof is omitted here.

  The handrail device of the present invention is mainly used in the field of care and welfare.
