Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a barrier-free entrance chair.
[0002]
[Prior art]
Special considerations for those who are not able to perform the same actions as healthy people (healthy people), such as those who have recently diminished function in some or all of their bodies, such as the elderly (old people) and disabled people It was way.
[0003]
In other words, it is essential for a healthy society that elderly people and persons with disabilities become independent and actively participate in society. Therefore, it is difficult to grasp the state of handy correctly and use equipment and tools. (Barrier) is eliminated, that is, the barrier free is closed up.
[0004]
By the way, one of the barrier-free designs for elderly people in the home is considered to be barrier-free in standing crouching, and this makes standing crouching harder as it gets older, and the operation of standing crouching tends to lose balance. From the viewpoint of, for example, installation of entrance benches and entrance chairs that can be used for standing crouching at home entrances to make it easy to move up and down in the vicinity of a raised town, that is, to remove and remove shoes and other footwear. Is encouraged.
[0005]
The following proposal is introduced about this entrance chair (refer patent 3051815 gazette).
[0006]
This will be described with reference to FIG. The figure is a schematic view of the entrance of a general household, and the entrance floor 101 and the entrance soil 102 are formed on the border of the uphill 100, and the following entrance chair 103 is raised on the entrance soil 102 and It is installed along the entrance wall 104.
[0007]
This entrance chair 103 is formed of a decorative plywood or a wooden board with a decorative veneer attached thereto, and a quadrangular seating top board 105 for an elderly person or the like to sit down. It comprises a pair of left and right rectangular legs 106 and 106 to be supported. The leg portion 106 is also formed of a decorative plywood or a wood board.
[0008]
According to the entrance chair 103, the uphill 100 is low (about 10 cm) at a general entrance, so that a burden is placed on the legs and legs during the operation of attaching and detaching footwear to an elderly person. It is supposed that a foot is not put on the board 105 because the foot is temporarily put on and removed from the board 105 and then moved to the entrance floor 101 or the entrance soil 102.
[0009]
[Problems to be solved by the invention]
However, the entrance chair 103 has a problem in that it does not sufficiently satisfy the requirement that the elderly person's crouching operation is easily out of balance, which is one of the barrier-free designs for the elderly person. It was.
[0010]
That is, there is a problem that the stability of the entrance chair 103 is not sufficiently considered against the imbalance of the movement of the elderly.
[0011]
Of course, if the entrance chair 103 is firmly fixed to the riser 100, the entrance wall 104, etc., the chair can be prevented from overturning. However, if such a fixing means is used, it is expensive, and any home entrance is used. Can not be adopted because it is not applicable.
[0012]
Therefore, the present invention aims to provide an entrance chair that is inexpensive and excellent in versatility, on the occasion of solving such a problem.
[0013]
[Means for Solving the Problems]
In order to achieve such an object, the gist of the present invention is as follows: 1) A front door formed between a front floor and a front soil with a rising town as a boundary, and used as an entrance chair for elderly people to squat down. Is formed in a horizontally long rectangular shape having a seat surface as a top plate without protrusions and a bottomless foot space, and the width of the seat surface is defined as a seating space and a space with two hands of the elderly. The elderly person's gripping heel is extended only to the front edge of the seating surface, and a grounding portion for preventing overturning is stretched below each front end surface of the side plates that support the seating surface at the end. The barrier-free entrance chair is characterized in that the entrance chair does not fall over even when the elderly are standing and crouching. 2) The amount of overhang of the fall-preventing grounding portion is in the overhanging quantity and the swollen weight of about 1cm to correct non-horizontal of entrance Doma In claim 1 which forms barrier-free according - in for entrance chair.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The invention will be described in more detail by means of an embodiment shown in the accompanying drawings.
[0015]
1 is a longitudinal sectional view of the embodiment of the present invention (cross-sectional view of arrow A in FIG. 2), FIG. 2 is a partially cut front view of FIG. 1, FIG. 3 (A) is a side view of FIG. FIG. 4 is a detailed view of the components, and the same or equivalent parts as those in the conventional example shown in FIG.
[0016]
The entrance chair (also referred to as a bench) 1 according to the embodiment of the present invention is made of wood (of course, it is not limited to natural wood and may be a wooden-like material suitable for installation at the entrance, such as a synthetic resin molding material for replacing wood). In this case, it is simply installed in the front door 102 composed of anti-slip tiles, decorative bricks, and concrete placing surfaces. Therefore, the tip of the leg portion 2 of the entrance chair 1 is not installed in the entrance soil 102.
[0017]
This front chair 1 supports a top board 3 as a seating surface by a pair of plate-like leg portions 2 and 2 that are provided at the ends of both sides (referred to as lateral or left and right sides) in a front view. Therefore, it can be said that the entrance chair 1 is configured in a rectangular parallelepiped shape having a bottomless foot space.
[0018]
In the portal space formed by the top plate 3 and the legs 2 and 2, a drawer 4 for storing slippers and the like is provided. Further, the top plate 3 has no protrusions such as handrails and forms a simple flat surface.
[0019]
Therefore, the entrance chair 1 is installed between the entrance soils 102, the outer side surface 5 of one of the legs 2 is raised and contacts the front end surface of the town 100, and the rear edge 6 of the top plate 3 and the leg 2 The rear end surface 7 can be installed so as to contact the entrance wall 104. This installation can be made on either the left or right side as viewed from the front of the entrance of the entrance soil 102. In other words, it can be used left or right.
[0020]
As described above, the entrance chair 1 is preferably installed in the corner of the rising town 100 and the entrance wall 104, but of course, depending on the specifications of the entrance, it may not be able to contact the entrance wall 104. In order to move to the entrance floor 101 (of course, including the entrance hallway) 101, it is installed so as to be in contact with the front end face of the uptown 100.
[0021]
Therefore, when an elderly person who is a user takes off his / her footwear, he sits on the top plate 3 which is the seating surface of the entrance chair 1 and then removes the footwear. If you put your foot down and then stand up, you can move your body up and down without placing a burden on your legs, and you can get up easily. Further, when this elderly person or the like wears footwear, the opposite operation may be taken.
[0022]
Here, the entrance chair 1 is provided with the following measures for preventing overturning. That is, even if an elderly person or the like is crouched and crumbles and the balance of the operation is likely to be lost, the entrance chair 1 is prevented from falling as follows.
[0023]
First, since the depth of the top board 3 is not seated for a long time, the depth of the normal work chair is shorter than 38 cm to 42 cm, and is about 35 cm, and the area occupied by the entrance soil 102 is reduced to reduce the size. For that reason, the horizontal width of the top 3 is not only the seating space for the user, but also the horizontal width (about 60 cm) for the space where the parties hold both hands when crouching while standing. In addition to being able to squat down, the chair is expanded laterally for stabilization. Therefore, it can be said that the rectangular parallelepiped is configured in a horizontally long rectangular parallelepiped shape (a rectangular parallelepiped shape).
[0024]
Next, on the top plate 3, only the front edge of the top plate 3 is integrally extended forward (referred to as the front direction orthogonal to the left-right direction), and the top plate 8 is gripped when standing by a senior citizen or the like. Formed in the part.
[0025]
For this reason, the overhanging amount of the ridge 8 is about twice as long as the thickness of the top plate 3 that can withstand shocking seating load and does not deform (for example, 2 cm for natural wood). It overhangs (4-5cm) to make it easier to grip.
[0026]
Therefore, it is not necessary to secure the seating surface expansion and foot space (the space where the heel of the foot can be pulled backwards when seated) as with a conventional top plate, but it projects forward for easy gripping. It is assumed to be 庇 8.
[0027]
Therefore, according to this top board 3, when a user who is an elderly person is standing and crouching, he / she can move while holding his / her hand on the top board 3 and holding the heel 8 together with sitting and standing. As well as making it easier, it prevents the balance of movement.
[0028]
In particular, it is recommended to sit with both hands on the top plate 3 when sitting, and to stand by holding the heel 8 when standing.
[0029]
On the other hand, by forming such a saddle 8 (compared to a chair formed entirely in a rectangular parallelepiped shape), a forward tilting moment is likely to occur. Therefore, the saddle 8 is formed only on the front edge of the top board 3, The rear edge 6 and the side edges 15, 15 of the top plate 3 are not formed with ridges but are flush with the rear end surface 7 and the outer surface 5 of the leg 2 in the vertical direction.
[0030]
Therefore, the rear edge 6 and both side edges 15 and 15 of these top plates 3 are prevented from being gripped by the elderly, thereby avoiding a concentrated load of weight due to gripping.
[0031]
Even if concentrated loads from above are applied to the rear edge 6 or both side edges 15 and 15 of the top plate 3, these loads are immediately supported by the legs 2 and 2, and the occurrence of a moment that falls is prevented. In addition, it can be installed in close contact with the rising town 100 and the entrance wall 104, and at least there is no rearward or sideways fall of the entrance chair 1, and it is as if fixed to these members.
[0032]
In particular, when standing while holding the heel 8, the front chair 1 falls backward, which is prevented. In addition, this saves the area occupied by the entryway 102.
[0033]
On the other hand, since there is a risk of the fall of the saddle 8, especially a forward fall moment, the following fall prevention measures are provided.
[0034]
As described above, since the leg portion 2 which is a side plate is made of a plate body, plate processing in a side view can be easily performed, and therefore, the amount of forward protrusion of the flange 8 only below the front end surface 9 of the leg portion 2. A fall prevention grounding portion 10 having a larger forward overhang amount is formed, and this formation is easily processed.
[0035]
In the figure, the front grounding portion 10 and the rear grounding portion 10 are formed separately to avoid making the grounding portion a solid surface, but a solid surface may be used.
[0036]
The amount of overhang of the fall-preventing grounding portion 10 is determined by investigating a lot of entrance soil 102 and, according to an experiment, when the height of the seat surface (top plate 3) described later is about 38 to 40 cm, It has been found that an increase of at least about 1 cm from the overhang amount of the ridge 8 is sufficient.
[0037]
In other words, if the amount of overhang prevention grounding portion 10 is made equal to the amount of overhang of ridge 8, the entrance soil 102 is not exactly horizontal but is inclined for running water or has a surface roughness. However, if the entrance chair 1 is slightly bent forward, a forward tilting moment will occur, so if it is made equal, the non-horizontalness between these entrance soils cannot be corrected, and this is more than 2 cm. For this reason, the fall prevention is not particularly improved, but rather it is hooked on the foot or occupies the space between the frontal soil 102, so it is slightly about 1 cm.
[0038]
Therefore, according to this entrance chair 1, when an elderly person tries to sit or stand while holding the heel 8, a concentrated load which is a part of the weight acts on the heel 8 from above, but this is overturned. It supports by the grounding part 10 for prevention, and does not generate a fall moment. Therefore, the front chair 1 does not fall forward.
[0039]
The fall prevention grounding portion 10 will be further described. In FIG. 1, A is the amount of overhang of the entire heel 8, a is the amount of overhang of the heel 8 in the leg 2, and B is the grounding dimension of the fall prevention grounding portion 10 that supports and supports this A. And the amount of overhang that corrects the non-horizontalness between the front doors 102 is shown. “b” represents the sum of the overhang amount “a” and the overhang amount “c” that corrects the non-horizontalness between the entrance soils 102.
[0040]
In addition, the height of the seat (top 3) of the entrance chair 1 is about 38 to 42 cm from the surface of the entrance soil 102 in order to facilitate standing crouching, and corresponds to the height of 38 to 40 cm of the chair for light rest. ing. Therefore, it is slightly lower than a general chair seat surface.
[0041]
In FIGS. 1 and 2, reference numeral 11 denotes a handle of the drawer 4, 12 denotes a shelf board, 13 denotes a cross rail, and 14 denotes a rear board. The drawer 4 is single-stage or double-stage, but in any case, a bottomless foot space is left below.
[0042]
Next, in the front chair 1 of this embodiment, the following stick support 16 is detachably provided on either the left or right side edge 15 of the top board 3.
[0043]
In FIG. 3B, (B1) is a partially cutaway plan view, (B2) is a longitudinal sectional view, and (B3) is a front view, but this stick support 16 is a U-shaped wooden frame in plan view. The U-shaped connecting portion 17 is joined to the outer surface of the side edge 15 and attached. For this reason, the screw through holes 18 are provided in both U-shaped leg portions, while the two embedded nuts 19 are provided on both side edges 15 of the top plate 3, and the stick support 15 is screwed 20.
[0044]
Of course, the entrance chair 1 is installed so as to enter the entrance as described above and to contact either the left or right entrance wall 104 when viewed from the front, so that the walking stick support 16 is also attached to any anti-entrance floor 101 side. Install it.
[0045]
The barrier free entrance chair of the present invention is suitable for the embodiment, but it may be installed not only in ordinary households but also in other entrances, and may be used by people other than the elderly. Of course.
[0046]
【The invention's effect】
According to the present invention, the space for the elderly with both hands on the seat surface of the entrance chair and the grip for the handrail instead of the handrails are provided only on the front edge of the entrance chair, taking into account the smoothing of the crouching operation by the elderly. Therefore, the reliability of the barrier-free front chair can be improved.
[0047]
Not only this, but also a chair fall prevention measure due to the provision of a heel, that is, a fall prevention measure that was directly connected to the heel one-on-one, so the chair fell over due to the balance of movement of the elderly In addition, the reliability of the barrier-free front chair can be improved.
[0048]
In addition, the chair is configured in the shape of a rectangular parallelepiped, and the protrusions are eliminated from the top plate, which is the seating surface. This makes it easy to change the direction of the body around the buttocks, and it can be installed in close contact with the riser and the entrance wall. In addition, a simple and inexpensive chair can be provided.
[0049]
In addition, considering the non-horizontal nature of the entrance soil, a grounding part for preventing overturning has been provided in consideration of the safety factor, so it can be installed with peace of mind while being compatible with most entrance soils and maintaining versatility. Can do. In other words, it is easy to handle and extremely simple, but even when an elderly person is crouching, it can be made difficult to fall down.
