Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail device to be installed and used in a toilet, a bathroom, a doorway, and other places inside and outside a building. More specifically, the present invention relates to a handrail device which can be easily attached to a wall surface or the like. The present invention relates to a handrail device that can be freely stored and taken out.

[0002]

2. Description of the Related Art In the case of handrails that are attached to the walls of toilets or bathrooms for persons with disabilities, such as the physically handicapped and the elderly, the amount of protrusion of the handrail from the wall is overwhelming compared to normal handrails. Grows to. This is because the handrail extends long in the direction (horizontal direction) orthogonal to the wall surface. As a specific example, in the case of a handrail composed of an inverted U-shaped pipe or a horizontally elongated pipe, the width (horizontal dimension) = 700 mm,
Length (vertical dimension) = 180 mm, pipe diameter = 32
mmφ, and the handrail projection amount from the wall surface is about 700 mm. Since such a handrail simply becomes an obstacle when it is not used, it is desired that it can be stored without being bulky when it is not used. In addition, the storage type handrail requires technical consideration for storing and taking out the handrail by a simple operation.

As a handrail storage means that meets the above demands,
Various types such as a flip-up type (vertical rotation type) and a lateral swing type (horizontal rotation type) are disclosed in Japanese Utility Model Laid-Open No. 5-31697. When the flip-up type handrail storage means is used, a horizontal handrail protruding in a direction orthogonal to the wall surface can be flipped up vertically and stored on the wall surface side. When using the lateral swing type handrail storage means, it is possible to store the handrail along the wall surface while rotating the handrail in the horizontal direction in the horizontal state.

[0004]

When the storage means for the handrail is a flip-up type and the handrail has the specifications described above, when the handrail is changed from the use state (horizontal state) to the storage state (vertical state). In addition, the protrusion amount is reduced from 700 mm to about 180 mm. However, in the stored state, 1 from the wall
In the case of a handrail that protrudes by as much as 80 mm, there is still a danger as an obstacle. Therefore, the flip-up type is not a perfect storage means for the handrail.

When the handrail storage means is of the lateral swing type and the handrail has the above-mentioned specifications, the handrail is stored so as to stick to the wall surface, and the protrusion amount is drastically reduced from 700 mm to 32 mm. That is, a desired storage state of the handrail can be obtained. However, when the handrail is stored or taken out in this way, the handrail having a turning radius of 700 mm is horizontally swung, so that it is essential to secure a large space in the region where the handrail moves. This means that there must be considerable room for the handrails. Therefore, in a toilet or bathroom in which the internal space is originally small and utensils such as toilets and bathtubs are arranged near the wall, it is difficult to equip the handrail itself when the storage means is a lateral swing type.

As a means for storing and taking out the handrail without making it bulky, it is convenient to operate the handrail in one direction, but it is too difficult to operate. It becomes impossible to escape from the above-mentioned flip-up type and lateral swing type, and these problems cannot be solved.

As an alternative to the above-mentioned two types, for example, it is possible to move the handrail in two directions and store it without making it bulky. In the case of the handrail storage means based on such an idea, in addition to the fact that the operation can be performed easily and lightly and the configuration is simple, erroneous operation can be prevented in advance, and there is a risk that the handrail will suddenly drop in the removal direction. Not required is also required. However, at present, there is not provided a handrail device which can satisfy these requirements and store the handrail without making it bulky.

SUMMARY OF THE INVENTION In view of the above technical problems, the present invention has a handrail storage state that is not bulky, effectively uses an excess space and expands an applicable range, stability during use, and simple and light operation. The present invention aims to provide a handrail device that can be improved in safety, prevent erroneous operation, prevent the handrail from dropping suddenly, and simplify the configuration.

In the handrail device according to the present invention, the following means are also desirable in order to achieve the intended purpose.
One of them is that, as described in claim 3, the clutch element is attracted to the clutch body side via a tension spring extending between the clutch element and the clutch body.
The other one is that, as described in claim 4, a resistance spring that resists the rotational force due to the weight of the rotating body is mounted between the fixed shaft and the rotating body. Still another one is that, as described in claim 5, a damper that resists the rotational force due to the weight of the rotating body is mounted over the fixed shaft and the rotating body. Another one is that the fixed shaft is fixed to both ends of the fixed shaft on the mounting seat. As for one other than these, as described in claim 7, the handrail is U
The U-shaped frame has a connecting end on one end side and a U-shaped collision end with the handrail mounting surface on the other end side. In this case,
As described in claim 8, it is provided with a receiver that is attached to the handrail attachment surface corresponding to the collision end portion of the handrail. In addition, as described in claim 9,
In some cases, the collision end of the handrail and its receiving member have relative concave portions and convex portions, and form a mating pair.

[Operation] The handrail device according to the present invention is mounted on a mounting surface (for example, a wall surface) at a place where the handrail is required. Therefore, the fixed shaft is attached horizontally to the wall surface. The rotating body having the fixed axis as a fulcrum is orthogonal to the fixed axis and can rotate within a range of about 90 degrees from the horizontal position to the vertical position. The handrail is connected to a clutch body fitted in the rotating body so that the handrail can rotate about the longitudinal axis of the rotating body.

The handrail in use is in a horizontal state and extends in a direction orthogonal to the mounting surface. The reason why the handrail during use is kept horizontal is that the collision end (fulcrum end) side of the handrail that has dropped due to its own weight hits the mounting surface and cannot rotate any more. Further, the handrail in this state cannot rotate in the clockwise direction (or counterclockwise direction) about the axis line along the length direction. This is because the clutch body, which is integral with the handrail, meshes with the clutch element, and the clutch element blocks the rotation of the clutch body, as will be understood from the description below.

When the handrail which has been in use is stowed when it is not used, the handrail is first raised in the vertical direction and rotated, and then the handrail is rotated clockwise around the axis along the length direction of the handrail. Rotate (or counterclockwise). At this point, the handrail can be rotated in this manner because the clutch element disengages from the holding groove of the clutch body and fits into the disengagement groove of the fixed shaft, as can be understood from the description below. Because it is crowded. Thus, when the handrail is stored, it appears as if it were attached to the wall surface. Even in the handrail storage state, for example, when the clutch element is inside the boundary between the vertical cylinder and the horizontal cylinder and is in contact with the rear surface of the inner wall of the boundary, the clutch element moves in the handrail extraction direction with respect to the clutch body. Because it blocks rotation,
The handrail does not fall down. When taking out the stored handrail when using it, the handrail may be operated in reverse of the storing procedure.

The handrail device according to the present invention and the receiver 201 and the holder 301 related to the handrail device illustrated in FIGS. 1 to 17 are necessary mainly for physically handicapped persons inside and outside the building. Where it is equipped. More specifically, the inner wall surface of the toilet, the inner wall surface of the bathroom, the inner wall surface of the entrance, and the inner and outer wall surfaces of the entrance / exit are mounted as mounting surfaces. Hereinafter, a mode in which the handrail device, the receiving member 201, the holder 301, etc. of the present invention are mounted on a required mounting surface and used will be described.

As will be apparent from FIG. 1, the mounting seat 1 is applied to the mounting surface (wall surface) 401 of the building, and
It is attached to the wall through a plurality of screws penetrating the seat plate 2 of the attachment seat 1 and screwed into the wall. When the mounting seat 1 is thus mounted on the wall of the building, the fixed shaft 11
Is in a horizontal state, and the rotating body 21 and the handrail 101 held by the rotating body 21 can rotate about the fixed shaft 11 in the directions of arrows R ₀₁ -R ₀₂ in FIG. 1. The handrail 101 can also rotate about the axis of the vertical cylinder 33 in the directions of arrows R ₀₃ -R ₀₄ in FIG. 1.

When the handrail 101 is taken out in the state shown by the solid line in FIG. 1, the collision end portion 1 of the handrail rod portion 103 is taken out.
06 or the cap 109 is the mounting surface 401 of the building.
Turn to the side and approach this. The receiving tool 201 corresponding to the cap 109 is applied to this location on the mounting surface 401, and then attached to a predetermined location with a plurality of screws that penetrate the seat plate 202 of the receiving tool 201 and are screwed into the wall. Therefore, when the handrail 101 is taken out in the state shown by the solid line in FIG. 1, the cap 109 covers the receiving member 201, and the concave portions 107 and the convex portions 203 are fitted to each other.

When the handrail 101 stands up in the state shown by the alternate long and short dash line in FIG. 1, the handrail rod portion 102 approaches the mounting surface 401 of the building. The rod portion 102 in this state
Holder 30 for receiving and holding a portion of
1 is attached to a predetermined position on the attachment surface 401. That is, the holder 301 is attached to the attachment surface 401 as shown in FIG. 1, and then attached to a predetermined wall surface portion through a plurality of screws that penetrate the seat plate 303 of the base 302 and are screwed into the wall. . When the handrail rod portion 102 is fitted inside the holder 301 as shown by the alternate long and short dash line in FIG. 1 or is escaped from the inside of the holder 301 as shown by the solid line in FIG. The opening and the entrance 305 of the holder ring 321 and the entrance and exit 322 of the pressing ring 321 open the front surface of the holder 301. Further, when the handrail rod portion 102 fits inside the holder 301 and the handrail 101 is along the mounting surface 401 as shown by the chain double-dashed line in FIG. 1, the inlet / outlet 316 of the rotating ring 315 turns to the inside of the base 302. The holder 301 comes to be closed and the front surface of the holder 301 is closed.

When not in use, the handrail 101 is housed as shown by the chain double-dashed line in FIG. 1 and stuck to the mounting surface 401. Therefore, the handrail 10 stored when not in use
1 does not bulky protrude from the mounting surface 401. Figure 2
Shows the main part of the device in the handrail storage state. As is clear from FIG. 2, the clutch main body 51 has one end portion of the holding groove 53 and the tip end surface of the stopper pin 58 facing the front surface of FIG. Against the cross. The lower surface of the clutch body 51 pushes down the clutch element 61 in the holding space 42 of the rotating body 21 against the tension spring 57, and pushes the clutch element 61 into the disengagement groove 12 of the fixed shaft 11. In this case, the clutch element 61 fitted in the disengagement groove 12 of the fixed shaft 11 cannot be escaped from here because it is pressed into the clutch main body 51, and the clutch main body 51 also has its lower surface. Since the clutch element 61 bites like a wedge between the release groove 12 and the release groove 12,
It cannot rotate in the direction of arrow R _{01 in} FIG. Moreover, both rollers 63a, 63b of the clutch element 61 are in contact with the rear wall surface of the holding space 42. Therefore, the handrail 101 in the stored state does not fall down due to its own weight or external force. In the handrail storage state, the holder 301 also receives the handrail rod portion 102 (the portion to which the grip 107 is attached) inside, and the rotating ring 315.
The inlet / outlet 316 of the holder wraps around the inside of the base 302 to close the front surface of the holder 301. Therefore, the handrail 101
If the holder receives the external force of its own weight and falls, the holder 30
It is also prevented by 1.

When the handrail 101 in the stored state is taken out, first, the handrail 101 is rotated in the direction of arrow R _{03 in} FIG. 1 to bring it into the state shown by the alternate long and short dash line in FIG. FIG. 3 shows the main part of the apparatus in this state. Handrail 10 in the stored state
When 1 is operated in this manner, as shown in FIG. 3, the holding groove 53 on the lower surface of the clutch body 51 is disengaged from the disengagement groove 12 of the fixed shaft 11 and the clutch element 61 fitted in the disengagement groove 12. Parallel. At the same time when this state is reached, the clutch element 61 receiving the force of the tension spring 57 fits into the holding groove 53 of the clutch body 51. That is, the handrail 101 rotates in the stored state (arrow R in FIG. 1).
_The clutch element 61 that has blocked the ( ₀₁ direction)
Since it is just accommodated in the holding space 42 of No. 1 and the holding groove 53 of the clutch body 51, the handrail can be rotated in the direction of the arrow R ₀₁ . Further, the holder 301 that has received the rod portion 102 of the handrail 101 therein also rotates the rotating ring 315 in the same direction as the handrail 101 rotates in the direction of arrow R _{03 in} FIG. Three
Align 16 with the other doorways 305, 322. That is, the front surface of the holder 301 is opened. Therefore, the holder 3
01 also enables handrail rotation in the direction of the arrow R ₀₁ . Note that the rotating ring 315 together with the handrail 101 is indicated by an arrow R in FIG.
_The grip 107 rotates in the ₀₃ direction when the rotating ring 3
This is because it is elastically deformed within 15 and is in strong contact with the inner surface of the rotating ring.

After the handrail 101 is in the state shown by the alternate long and short dash line in FIG. 1, it is rotated in the direction of the arrow R ₀₁ in the figure to obtain the state shown in the solid line in FIG. That is, the handrail 101 in the upright (almost vertical) state is tilted horizontally and taken out. Figure 4
Indicates the main part of the apparatus in this state. As is apparent with reference to FIG. 4, when the handrail 101 is operated in this manner, the rotating body 21 rotates about the axis of the fixed shaft 11 in the direction of the arrow R ₀₁ , as is obvious. Therefore, the vertical cylinder 33 of the rotating body 21 also falls from the vertical state to the horizontal state.
Further, the clutch element 61, which is in the holding space 42 of the rotating body 21 and fits in the holding groove 53 of the clutch body 51, is also held by the clutch body 51, and the fixed shaft 11 is held.
4 rolls on the outer peripheral surface and is displaced to the front of the fixed shaft 11 in FIG. In this handrail take-out state, the clutch element 61, which acts as a wedge between the lower surface of the clutch body (holding groove 53) and the outer peripheral surface of the fixed shaft, has the handrail 101 swinging in the directions of arrows R ₀₅ -R _{06 in} FIG. 4. Prevent (shake). Therefore, the handrail extraction state is stable. In the state shown in FIG. 1 where the handrail is taken out, the cap 109 at the tip of the handrail rod portion 103 is the receiving member 201 on the mounting surface 401 side.
The cap 201 and the receiving member 201 in the recess 110 of the cap 109.
Since the convex portion 203 is fitted, the fitting of the cap 109 and the receiving member 201 also prevents the handrail swing in the direction of the arrow R ₀₅ -R ₀₆ . Since the collision end portion 106 of the handrail rod portion 103 indirectly abuts the mounting surface 401 via the cap 109, the receiving member 201, and the like, the person who holds the handrail 101 (person with a physical disability) in FIG. Arrow R ₀₇
Even if a load is applied in that direction, the handrail 101 does not move in that direction.

When the handrail 101 is changed from the one-dot chain line state in FIG. 1 to the solid line state, the handrail 101 after it has escaped from the holder 301 is rotated by its own weight in the arrow R ₀₁ direction in FIG. In this case, the resistance spring 71 mounted over the spring holder 72 on the fixed shaft 11 side and the protrusion 27 on the rotating body 21 side is unwound by receiving the force in the unwinding direction (the direction of the arrow R ₀₁ ). Or, while receiving the force in the winding direction and being wound, it exerts a reaction force against this. In addition, a plurality of fixed disks 82, a plurality of rotating disks 85, a viscous body 9
In the damper 81 mainly composed of 0, etc.,
Each fixed disk 82 does not rotate on the fixed shaft 11, but each rotary disk 85 rotates in the direction of the arrow R ₀₁ together with the rotating body. In this case, the viscous body 90 interposed between each fixed disk 82 and each rotary disk 85 exhibits a high degree of shear resistance depending on its own viscosity. Therefore, the handrail 10 when taking out from the state of FIG.
Since the reaction force of the resistance spring 71 is generated and the shearing resistance of the viscous body 90 is generated in the damper 81, No. 1 rotates at a low speed in the direction of the arrow R ₀₁ . That is, the handrail 101 does not drop suddenly.

When the handrail 101 in the take-out state (state shown by the solid line in FIG. 1) is to be stored, the handrail 10 is reversed in the reverse order.
Operate 1. That is, first, the handrail 101 is rotated in the direction of the arrow R _{02 in} FIG. 1 to bring it into the state of the one-dot chain line in FIG. 1, and then the handrail 101 is rotated in the direction of the arrow R _{04 in} FIG. Put it in a broken line.

In the above, the clutch element 61 prevents the handrail 101 from swinging in the direction of the arrow R ₀₅ -R _{06 in} FIG. 4 from the state shown by the solid line in FIG. 1 to the state shown by the alternate long and short dash line. To do. This is as described with reference to FIG.
This is because the clutch element 61 is interposed between the lower surface of the clutch body (holding groove 53) and the outer peripheral surface of the fixed shaft and acts like a wedge. When the handrail 101 reaches the state shown by the alternate long and short dash line in FIG. 1, the handrail rod portion 102 (the portion provided with the grip 107) is fitted into the holder 301 having the front surface opened, and the state shown in FIG. 3 is obtained. . Thereafter, by rotating the handrail 101 in the direction of the arrow R _{04 in} FIG. 1, the main part of the apparatus is displaced to the state of FIG. 2, and the handrail storage state shown by the chain double-dashed line in FIG. Further, in the holder 301 which receives the handrail rod portion 102 inside, since the rotating ring 315 rotates together with the handrail 101 in the direction of arrow R _{04 in} FIG.
The inlet / outlet 316 of No. 5 goes around the inside of the base 302. Therefore, in the handrail storage state shown in FIG.
The front surface of the holder 301 is also closed. Here the rotating ring 3
The reason why 15 rotates in the direction of arrow R _{04 in} FIG. 1 together with the handrail 101 is that the grip 107 is elastically deformed and strongly contacts the inner surface of the rotating ring 315 as described above.

In the state of FIG. 3, the clutch body 5
When the handrail 101 is rotated in the arrow R ₀₄ direction (storage direction) in FIG. 1, the stopper 58 on the right side of 1 rotates around the free space 43 of the rotating body 21 in the same direction. When the state shown in FIG. 2 is reached, the stopper 58 hits the collision surface 45 (shown in FIG. 7) of the collision step portion 44. This stopper collision occurs just before the handrail 101 comes into contact with the mounting surface 401 during storage. Therefore, when storing the handrail 101,
Handrail 101, even if it is turned vigorously in the direction of arrow R ₀₄
Does not collide with the mounting surface 401. Further, even when the handrail 101 in the state indicated by the alternate long and short dash line in FIG. 1 is rotated in the direction of the arrow R _{03 in} FIG. 1 when the handrail 101 is stored, the collision surface 46 of the collision step portion 44 and the stopper 58 cooperate to mount the handrail 101. A handrail collision with the surface 401 is prevented as described above.

The illustrated handrail device according to the present invention also uses related parts such as the receiver 201 and the holder 301. These handrail device, receiver 201, holder 301
Examples of the material include well-known metals, well-known synthetic resins, well-known rubbers, and composite materials thereof. In particular, these materials are selected in consideration of required mechanical properties, workability, airtightness, and the like. For example, an O-ring made of rubber is used to give priority to airtightness, and a spring type is made of metal having such physical properties to give priority to elasticity. Metals are used as the class and washers. Based on the required characteristics, the materials and materials that have already been explained and parts other than the above will be
Mainly metal processed products are used, but in some cases synthetic resin products are also used. As a typical example of the handrail 101, a metal pipe whose surface is covered with a synthetic resin is used, and the grip 10 made of rubber or synthetic resin is used.
7 is attached.

The handrail device according to the present invention is used together with the receiving member 201, the holder 301 and the like in the above-described use mode. Here, if one set of the device of the present invention, one receiving member 201, one holder 301, etc. are put together into one set, only one set of these may be used, or two or more sets may be used at the same place. By the way, when these are installed in the toilet, the above set is installed on the inner wall surface of the toilet in order to take out and store a pair of (two) handrails on both sides of one toilet.

In the above-described use mode, the handrail 101 in the take-out state (horizontal state) is rotated upward to be stored, but the handrail 101 in the take-out state (horizontal state) is rotated downward to be stored. There is also such a usage mode. In such a case, the handrail device in the previous example may be turned upside down and attached to the attachment surface 401, and the receiver 201, the holder 301, and the like may be attached to the attachment surface 401 in correspondence therewith. However, regarding the resistance spring 71, the handrail 10
This is mounted over the fixed shaft 11 and a part of the rotating body 21 so that the 1 resists the force of falling by its own weight. Also,
In such a usage example, the cap 109 on the handrail 101 side and the receiving member 201 on the mounting surface 401 side may be changed to a pair of male and female catching tools. For example, the pair of male and female catching tools are automatically engaged when the male and female tools are abutted, and when the release button is pressed, the engaging of the male and female tools is released.

1 is a fixing ring 35, a spacer 38, a clutch body 5
The movement in the axial direction is restrained via the flange 54 and the like formed in 1. As an alternative means, an annular groove is formed on the outer peripheral surface of the clutch main body 51, an arcuate groove is formed on the connecting end portion 105 of the pipe handrail 101, and a single or a plurality of stopper pins are formed on this. May be combined. When using such means, the vertical cylinder 3
The tip of the stopper pin fixed to the vertical cylinder 33 penetrating from the outside of 3 is inserted into the annular groove on the outer peripheral surface of the clutch main body 51 through the arcuate groove of the connecting end portion 105. Therefore, when such a means is adopted, the fixing ring 35, the spacer 38, the flange 54, etc. are unnecessary. Further, in an example in which one end (upper end in FIGS. 2 and 3) of the clutch main body 51 fitted in the vertical cylinder 33 of the rotating body 21 projects out of the vertical cylinder 33, one end of the clutch main body 51 and a handrail. The connecting end 105 of 101 is connected outside the vertical cylinder 33. At this time, as a connecting means,
A connection sleeve, a welding method, or a screw fastening method is used.

In the handrail device according to the present invention, the handrail 10

In the inside, the clutch element 61 fitted in the disengagement groove 12 of the fixed shaft 11 is pressed by the clutch main body 51, and this is just wedged between the lower surface of the clutch main body 51 and the disengagement groove 12. Instead, the front and rear surfaces of the clutch element 61 (the front peripheral surface and the rear peripheral surface of the rollers 63a and 63b) contact both front and rear wall surfaces of the holding space 42. In this case, the rear wall surface of the holding space 42 prevents the handrail 101 from falling forward, and the front wall surface of the holding space 42 has the handrail 1.
Prevents 01 from falling backwards. Therefore, in order to hold the stored handrail 101 in the upright state, it is desirable that the width of the holding space 42 and the width of the clutch element 61 are substantially the same (they are in close contact with each other) as described above.
The width of the holding space 42 may exceed the width of the clutch element 61 so that the clutch element 61 has a play in the holding space 42.

Further, in the case where the rotary body 21 is composed of only the vertical cylinder 33 and has the resistance spring 71 and / or the damper 81, the casing required for them is separate from the vertical cylinder 33. It is made and assembled in a predetermined place.

The above paragraph numbers [0059] to [0070]
Each item described in the column may be a combination of two or more items within a practicable range.

[0072]

The handrail device according to the present invention has the following effects.

When the handrail is stored when it is not used, the handrail seems to stick to the mounting surface, and the handrail can be stored without being bulky. Therefore, a situation in which the handrail when not in use is an obstacle can be avoided.

When the handrail is taken out or stored, it is turned horizontally or vertically, but the turning radius when turning the handrail horizontally is much larger than the turning radius when turning the handrail vertically. Small. In such a case, it is not necessary to secure a wide space in the horizontal rotation region of the handrail, and the handrail device can be installed even in a narrow internal space. Further, since there is an extra space in the vertical rotation area of the handrail, this can be utilized as it is. Therefore, it is possible to effectively use the surplus space and expand the applicable range.

The lateral deflection of the handrail taken out for use is prevented by the clutch body, the clutch element, the fixed shaft and the like working together. Therefore, it is possible to ensure stability when using the handrail.

When the handrail is taken out and stored, the handrail is simply rotated in two directions, so that the operation is simple. Further, when a resistance spring or a damper is provided as a component of the handrail device, the vertical rotation operation of the handrail can be easily performed.

An erroneous operation when the handrail is turned in two directions and taken out or stored, that is, an operation error such as horizontally rotating the handrail to be vertically rotated, or a vertical rotation of the handrail to be horizontally rotated. The clutch body, clutch element, fixed shaft, etc. work together to prevent operational errors. Therefore, it is possible to prevent erroneous operations that often occur when taking out and storing the handrail.

When the above-mentioned resistance spring or damper is provided as a constituent element of the handrail device, there is no fear that the handrail will drop suddenly during vertical rotation, which is safe.

Besides the handrail, it is mainly composed of a fixed shaft, a rotating body, a clutch body, a clutch element, etc., so that the structure can be simply summarized.

When the main components are assembled on the mounting seat, the handrail device can be easily attached to the mounting surface thereof. Also,

When the receiving device is combined, the handrail during use can be kept more stable through the receiving device, and the load applied to the clutch body, the clutch element, etc. can be reduced to avoid damage to them. can do.
