Description

  The present invention relates to a handrail for assisting walking of an elderly person, a sick person, and the like and capable of opening and closing the door even when attached to the surface of a sliding door.

  Conventionally, handrails have been attached to the walls of corridors in buildings such as houses, hospitals, nursing homes, etc., to ensure the safety of walking. There is no. When the door is opened and closed by a hinge like a door, even if a handrail is attached to the door, there is no hindrance to opening and closing the door, so a handrail may be attached rarely. There are even things that can be used as a handrail by changing the shape of the handle of the door. However, in the case where the structure for opening and closing is a sliding door using rails and a door pulley, if the handrail protrudes even slightly from the surface of the door, the handrail hits the door frame, so the door cannot be opened. Many inventions have been devised in view of this situation, but no technology has been used.

  Patent Publication 10-96375   Patent Publication 11-236755

  The present invention is a handrail for assisting the safety of walking of elderly people and victims, etc., and in order to be able to open and close the door even if attached to the surface of the sliding door, the surface on the opening side of the sliding door Attach a bracket with a fixed plate, a rotatable support, and a locking tool, and fix the base end of the handrail bar to the bracket via the locking tool, and the other end of the handrail bar to the wall Or it hold | maintains horizontally with the receiving tool provided in the eaves frame etc. And this other end part is made to slide up and down along a wall or a fence frame etc. in response to opening and closing operation of a sliding door.

According to Patent Document 1, hollow handrail bars with different thicknesses are attached to the two sliding doors, and when the sliding door is opened, a thin handrail enters the thicker handrail. A latch is attached to the two sliding doors and a handrail.
The first issue is the width of the sliding door from the surface of the sliding door of the bracket for attaching the handrail. However, considering that the thickness of the door usually varies depending on the type of the sliding door, the condition cannot be met. . For the latch, the structure is so complicated as to require a spring, so that the production cost is high, and it is necessary to perform processing such as cutting out a door to attach this, and labor and processing technology are required. In particular, it is extremely difficult to process a metal sliding door. In addition, the latch is a two-stage operation that lowers the handrail so that the sliding door does not move before opening the sliding door when a person relies on the handrail. If the sliding door moves even a little, it will not be latched and it is extremely dangerous. Also, when removing the sliding doors, you have to open both doors a little to hold the doors, but this is very difficult because the handrails are connected deeper and you have two sliding doors together. is there.
In Patent Document 2, when a person moves from the front side of the sliding door to the other side, the handrail has to be moved 90 degrees like a crossing barrier before opening the sliding door. After moving to the side, you must bother returning the handrail to its original position before closing the sliding door. Further, it is considered that the handrail is difficult to move when the sliding door is opened from the other side.
Many other applications of this type have been made, but each document has the same drawbacks as Patent Documents 1 and 2, although the structures are different.

  The present invention has the following configuration in order to solve the above problems. That is, as shown in FIGS. 1 and 4, the bracket 21 having the fixing plate 22, the rotation support 24 and the locking tool 26 is screw-fixed to an appropriate height of the sliding door 1 by the fixing plate 22. The handrail bar 11 is fixed to the bracket 21 by the locking member 26 at the base end 12 portion, and the other end portion 13 is fitted into the recess 32 (FIG. 5) of the receiving member 31 provided on the collar frame B6. It is held horizontally.

Effect of the invention

The operation of the present invention will be described in detail with reference to FIG. 1, FIG. 2, FIG. 3, FIG.
As shown in FIG. 1, a handrail bar 11 positioned horizontally on a sliding door 1 with an appropriate height is attached to a side where the sliding door 1 is opened via a bracket 21, and the length is the other end. The holder 31 is attached to a position where the other end 13 of the handrail bar 11 contacts the collar frame B6 until 13 contacts the collar frame B6. Further, since the horizontal core of the handrail bar 11 is located above the rotary core 25, the following actions are exhibited when the sliding door 1 is opened.
When the sliding door 1 is moved in the opening direction (arrow A), as shown in FIG. 2, the handrail bar 11 cannot be moved because the other end 13 cannot be moved by holding the collar frame B6. When the sliding door 1 continues to move in the direction opposite to the door (arrow B) with the support core 24 as the axis, the other end 13 slides upward on the surface of the frame B6. At the same time, the rotation support 24 continues to rotate, and when the sliding door 1 is fully opened as shown in FIG. 3, the handrail bar 11 is in a substantially vertical state. When the sliding door 1 is closed, the movement is completely opposite to that when the sliding door 1 is opened. At the same time as the sliding door 1 is completely closed, the other end 13 is accommodated in the support 31 so that it can be used again as a handrail. Become.
FIG. 4 is a cross-sectional view of the bracket 21. The fixing plate 22 fixed to the surface of the sliding door 1 is provided with a rotatable support 24 on the surface, and a locking tool 26 is provided on the upper part thereof. The handrail bar 11 is fixed with screws.
FIG. 5 shows a state in which the handrail bar is housed in the recess 32 formed in the receiver 31.

The invention's effect

In the present invention, the following effects can be obtained by the above configuration.
1. When the sliding door is closed, the handrail bar functions as a handrail, and the sliding door can be opened in that state, and when closing, it can be closed normally. Therefore, although it is a sliding door with a handrail, it can be used in exactly the same operation as a conventional sliding door.
2. The handrail stick can be attached simply by screwing the bracket and bracket to the sliding door and frame, etc., and there is no processing to the sliding door or building. Can do.
3. Since the installation method is only screws, it can be installed on most sliding doors without questioning whether the building is new or existing.
4). Even in the case of a double sliding door that opens to the left and right, it can be manufactured at low cost because it can be used for both the left and right sides by attaching a handrail bar to the bracket locking tool in the opposite direction.
5. When removing the sliding door, it can be easily removed by one person because the other end of the handrail bar is separated from the receiving device at the same time if it is opened a little to hold the door.

The first embodiment will be described in detail with reference to FIGS. 6, 7, 8, and 9.
FIG. 6 is a front view in which a single sliding door 1 is fitted in a sliding door frame composed of a vertical frame A5, a fence frame B6, and a sill 4 and a duck 7 although not shown, and rotates with a fixed plate 22 The bracket 21 including the support 24 and the locking tool 26 is screwed to an appropriate height on the opening side of the sliding door 1 by a fixing plate 22, and the handrail bar 11 is locked at the base end portion 12. It is fixed to the bracket 21 via a portion 26, and the other end portion 13 is provided with a guide roller 14 via a roller support 16. The guide roller 14 has shaft protrusions 15 formed on both sides of the roller support 16 so as to extend the shaft of the roller.
A guide rail 33 including a linear guide groove 34 and a bent portion 35 is provided on the collar frame B6 in place of the support 31 shown in FIG.
The guide rail 33 has a guide groove 34 formed therein as shown in the cross-sectional view of FIG. 9, and a bent portion 35 is formed at the lower end portion thereof as shown in FIG. -The length is set to compensate for the height when the clogging guide roller 14 reaches the top when the sliding door 1 is fully opened. Further, a notch 36 is provided near the center of the guide rail 33 for pulling out the guide roller 14 when the sliding door 1 is removed. The width of the guide groove 34 is slightly narrowed as it goes downward at the bent portion 35, and the width of the guide groove 34 matches the distance between the tip of the guide roller 14 and the axial convex portion 15 to match the guide roller and the axial convex portion. Is just fitting.
The guide roller 14 and the shaft convex portion 15 may be shared by the same member, and the guide roller, the shaft convex portion, and the roller support 16 are integrally formed as one unit, and this unit is used as a handrail bar. If the end portion can be fixedly mounted, it is possible to make adjustments such as shortening the length of the handrail bar.
The first embodiment having the above configuration has the following effects.
1. By the action of the guide roller provided at the other end of the handrail bar, the vertical movement accompanying the opening and closing of the sliding door can be made extremely smooth. Furthermore, since the guide roller moves in the vertical direction with respect to the horizontal movement of the handrail, even if it is a roller, some resistance is generated at the initial movement of the sliding door, but the sliding door is formed by the curved portion formed at the lower end of the guide groove. Most of the initial resistance can be eliminated.
2. When the sliding door is in a closed state, the movable direction of the other end of the handrail bar is only the angle of the bent part and the direction obliquely above the clogging, and the handrail bar does not move in any direction other than this direction. When an ordinary person relies on a handrail, the force applied to the handrail is mainly in the downward direction, and it is unlikely that the force works in an obliquely upward direction. Therefore, the handrail bar will not move unless it is intentionally moved in an obliquely upward direction, so it is extremely safe when using a handrail. In addition, if you pull the handle as it is, the sliding door can be moved. Can be opened.

Example 2 will be described in detail with reference to FIG.
In this embodiment, two sliding doors are drawn from the center toward both sides and are often used in hospitals and nursing homes. However, according to this method, handrails attached to the walls of the corridor are moved to the room. Only the doorway part is not attached. And the length of the part without a handrail reaches at least 2 meters. Therefore, in this embodiment, the left and right sides of the bracket, handrail bar, and guide rail are not determined in the same manner as in the first embodiment, and the guide rail is used as it is. The handrail bar may be symmetrical when the base end of the handrail bar is reversed and fixed on the locking tool, and a handrail can be attached to the sliding door portion extending over 2 meters.
Further, according to this configuration, even in the case of left-right symmetry, the same parts can be used as they are, so that the manufacturing unit price does not increase.

The third embodiment will be described in detail with reference to FIGS.
In this embodiment, as shown in FIG. 11, a flange 37 is formed linearly on the periphery of the guide rail 33. As shown in FIG. 12, the guide rail 33 itself has a flange 37 and a bent portion 35. If it is left and embedded in the sash frame B, the opening when the sliding door is opened to reduce the bulge is widened, and it is easy to wipe and is excellent in design.
From the viewpoint of design, it is also possible to eliminate the bracket locking tool and integrally form the handrail bar and the rotation support.
