FIGS. 18A and 18B show another embodiment of a handrail for fittings provided with automatic driving means and handrail interlocking means on both sides of the fitting, (a) usable state and (b) stored state.

In FIG. 1 to FIG. 4, a handrail 10 for a fitting according to the present invention is arranged so as to be substantially horizontal and substantially the same height as the handrail 3 on the wall only when the door 1 is used. The handrail body 11 in the housed state shown in FIG. 1 is projected substantially horizontally as shown in FIG. 4, and when not used, FIGS.
As shown in FIG. 4, a handrail main body 11 is provided inside the door 1 (a handrail main body 11 'shown by a two-dot chain line in FIG. 4).

As an example of the storage means, arms 12 at both ends supporting a handrail body 11 as shown in FIG. Handrail body 11 and arm 1
When the housing 2 is housed, the mechanism held by the magnetic force of the magnet 15 provided in the door 1 like the handrail body 11 'and the arm 12' in the housed state shown by the two-dot chain line in the door 1 is simple and easy to handle. Excellent and cheap (at least 12 arms
Alternatively, a magnetic metal such as iron attracted by the magnet 15 is disposed at a position corresponding to the magnet 15 of the handrail body 11. ).
Of course, in addition to the above-mentioned storing means, for example, a storing means by a rotating mechanism of the handrail main body 11 having a spring and a latching structure could be adopted.

In order to use the handrail 10 for fittings, the handrail body 11 'housed inside the door 1 as shown in FIG. By releasing the arm 12 ′ together with the arm 1 ′ substantially horizontally from the vertical plane of the door 1, the handrail body 11 is ready for use.

By the way, unless the person on the opposite side (inside of the room in FIG. 2) recognizes that the handrail 10 is in use or in a usable state and is protruding, the elderly person cannot use the handrail for the fitting. While using the slide 10, the door 1 is opened by the other person from the opposite side.
It is dangerous to open it unexpectedly. In this regard, there is little problem if the door 1 can be seen through the glass, but if not, the side of the door 1 opposite to the side where the handrail 10 for fittings is used (the front view in FIG. 2) is in a handrail use state. It is preferable from a safety point of view that a display notifying that the door 1 is visible so that a person does not open the door 1 from the opposite side.

The handrail use indication is, for example, a part of the shaft 13 or the end face 1 of the arm 12 in FIG.
The display section D in use may be provided in 2a, and the window 16 may be opened so that the display section D can be seen from the opposite side as shown in FIG. When the arm 12 or the shaft 13 is rotated by 90 degrees, the display unit D appears on the opposite front side in the use state.

Next, there is a possibility that the door 1 may be overlooked only by using the above-mentioned use display. Therefore, in order to further secure the safety of the handrail 10 for fittings, the door 1 is used from the opposite side during use of the handrail 10 for fittings. The lock mechanism L may be provided so that the door does not open immediately. For example, as shown in FIG.
The lock bar 17 of the lock mechanism L as shown in FIG.
It is configured to rotate around and protrude.

Next, from the opposite side (inside of the room), the handrail use state must be in the housed state, in other words, the lock must be released. It is often assumed that the elderly and the like do not return to the stowed state after closing and using the handrail 10 for fittings, so that when a person opens the door 1 from the opposite side, a protruding handrail is used. This is because the main body 11 may hinder opening and closing. So Figure 2,
As shown in FIG. 4, the door 1 can be opened and closed by storing the handrail body 11 and the arm 12 in the fitting by the unlocking operation as a structure provided with a release bar 18 that can be slid from the opposite side (indoor side). It is important to do so.
As the lock release mechanism K, for example, a means for rotating the handrail main body 11 and the arm 12 by a release bar 18 utilizing the principle of leverage around the shaft 13 as shown in FIG. 4 can be applied. A spring bias could be applied to increase the working force. The release bar 18 is returned to its original position by a spring or the like after the release.

As described above, the handrail for fittings 10 attached to the door 1 so as to have the same height as the handrail 3 on the wall has a planar structure as shown in FIG. 5 in a usable state. .

Next, the handrail 10 for fittings according to the present invention having the above structure can be basically applied to a sliding door. For example, as can be seen from the plan view showing the case of two sliding doors (sliding doors) in FIG. 6, when the sliding doors 20, 20 are in the use state of the handrail 10 for a fitting, the lock bar 17 (in comparison with the case of the door 1). Are also shortly protruded by about 20 to 30 mm.) And released by the release bars 18 respectively. In the case of the single sliding door 30 of FIG. 7, the arm 12 itself becomes a lock bar, and can be released by the release bar 18.

As shown in FIGS. 8 (a) and 8 (b), the handrails 40 for fittings move from the opened state to the closed state when the sliding door 30 is opened. The housed handrail body 11 automatically projects substantially horizontally with respect to the single sliding door 30 and is usable (it is important that the handrail body 11 has a protrusion dimension that can be used continuously at substantially the same height as the handrail 3 on the wall). ) Is provided.

The automatic handrail driving means is provided with a mechanism as shown in FIG. 9A, for example, in a usable state, and FIG. Is realized. That is, one shaft 31 (which does not rotate itself) is urged to the opening side (the left side in FIG. 9) by springs 32, 32 which are slidable about 10 to 50 mm in the lateral direction and are externally provided. In the state where 30 is open, the tip 31 of the shaft 31
a is configured to protrude from the side surface by 10 to 50 mm. A protruding member 34 is disposed at a position where the arms 12 and 12 of the shaft 31 are pivotally mounted. Is provided with a slit (or groove) 35 and is fitted with the projection member 34 on the shaft 31 side. Since the shaft attachment portion 12a of the arm 12 itself does not slide, when the protrusion member 34 slides along with the slide of the shaft 31, the slit (or groove) 35 fitted thereto is pushed by the protrusion member 34 and the shaft 31 Is applied. Thus,
When the sliding door 30 is closed, 10
The distal end portion 31a of the shaft 31 projecting from about 50 mm contacts the side surface of the wall and is retracted, and the shaft 31 slides against the spring 32, and at the same time, the single sliding door 3 in a vertical state.
The arm 12 and the handrail main body 11 housed in the housing 0 are rotated by about 90 ° to be ready for use. When the handrail is ready for use, the handrail can be unlocked by the lock bar 17 attached to the shaft attachment portion 12a of the arm 12 so as to protrude to the opposite side of the single sliding door 30, and released by the release bar 18. It is desirable to do. These are attached to the shaft attachment portion 12a on the side opposite to the arm 12 by 180 °.

Automatic driving means in the case of a single door can also be realized in the same manner as described above. For example, as shown in FIG. 10A and FIG. 10B, the distal end portion 31a of the shaft 31 is provided with a spring 32 on the side of the door 1 where the hinge 5 is provided. When the door is open, the door protrudes with the door open, and in the closed state, the shaft 31 is slid by retracting against the spring 32 to apply a rotational force to the shaft attachment portion 12a of the arm 12 by the same mechanism as described above. Rotate the arm 12 by 90 ° and move the handrail body 11
Is issued.

By the way, the door 1 can be easily seen from the opposite side (inside of the room) from the opposite side (inside of the room), like a glass door, to confirm that the handrail for fittings is usable. is there. In this case, it is often not necessary to force the release bar 18 to be stored by force (unlike the sliding door, the door can be generally opened even when the handrail main body 11 is exposed).
A lock release bar 27 (biased by springs 33, 33) for releasing the latch lock 6 of the door 1 as shown at 0 is provided separately or combined with the door knob so that the handrail can be opened in a usable state. You may.

Next, as shown in FIG. 11, the double sliding door 50 is provided with a handrail 4 for fittings provided on one sliding door 30a.
When 0 is changed from the housed state to the usable state, the handrail 41 for fittings in the housed state of the other sliding door 30b automatically comes out and is provided with an interlocking means that is brought into a usable state. In other words, when the handrail main body 11 is taken out from one sliding door 30a (or 30b) in a state where the opposite side surfaces of the double sliding door 50 are in contact with each other and the door is completely closed, the other sliding door 30b (or 30a). This is a mechanism from which the handrail body 11 comes out.

The mechanism of the interlocking means is, for example, as shown in FIG.
And the mechanism shown in the structural diagram of the usable state of FIG. That is, one sliding door 30
The tip 43a of the shaft 43 of the handrail for fitting a is a hexagonal shaft or a square shaft (not a circular shaft), and one end side 47a is fitted deeply into the shaft 4 so that
An interlocking member 47 transmitting the rotational force of No. 3 and having the other end 47b processed into a rectangular concave shape is attached to the distal end 43a of the shaft 43 of the sliding door 30a. The tip 44a of the other sliding door 30b facing the sliding door 30a of the shaft 44 is connected to the other end 47b of the interlocking member 47.
It is processed into a convex shape that fits into the rectangular concave shape. The sliding member 30 is slid in the sliding door 30a in the lateral direction to maintain the fitted state of the distal end 43a of the shaft 43 and the one end 47a while maintaining the fitted state of the sliding door 30b at the other end 47b. Interlocking lever 4 for attaching and detaching mating
It is desirable that an interlock 8 be provided so that the interlocking mechanism can be set / reset by sliding the interlocking lever 48 according to the situation (the right side in FIG. 12 is the interlocking state, and the left side is the interlocking release state). .

In the case of the double doors 50a and 50b as shown in FIG. 13, the interlocking means of the fitting handrails 51 and 52 can be realized in substantially the same manner as described above. FIG. 14A is a structural diagram of a usable state in an interlocking set state, and FIG. 14B is a structural diagram of a state in which a handrail is stored in an interlocking set state and immediately before opening a door 50b. In this figure, the shaft 5
The shafts 56 of the latch locks 52, 53 and 52 are hexagonal shafts or square shafts.
3 and a rectangular latch lock 52 so as to be engaged with the latch lock 52 to transmit a rotational force. When the interlocking lever 48 is slid to the left, the interlocking member 57 of the door 50a is slid to the left, disengaged from the latch latch 52, and the interlocking is released.

Further, even in the interlocked state as shown in FIG. 14 (b), the release bar 59 of the low-type latch lock 52 provided on the door 50b slides rightward in conjunction with the latch release operation of the door handle or the like. In this configuration, the connecting member 58 that connects the shaft 54 of the door 50b and the shaft 56 of the rotatable latch lock 52 slides, and the rotatable latch lock 52 retracts into the door 50b. ), The doors 50b and 50a can be opened without any trouble even if the handrail is usable.

The sliding door 20 can also be provided with interlocking means. FIGS. 15A and 15B are structural views for explaining the interlocking mechanism, wherein FIG. 15A shows a stored state and FIG. 15B shows a usable state. In this figure, sliding doors 20a, 20
In the overlapping portion of b, the leaf springs 62a, 62b are respectively curved in a semicircle along the circumference at the ends of both shafts 61a, 61b, and are regulated in a U-shape. It is arranged to be. FIG. 16 schematically shows the operation of the leaf springs 62a and 62b. In order to clarify the movement of the leaf springs 62a and 62b, each side surface is divided in half by white and black.

First, when the handrail main body 11 is in the housed state as shown in FIG. 16B, the leaf springs 62a and 62b are accommodated inside the sliding doors 20a and 20b, respectively, and the sliding door can be freely opened and closed. In state. Next, in the closed state, when the handrail main body 11 of the sliding door 20a is put out as shown in FIG. 16A to be in a usable state, the shaft 61a rotates together with the rotation of the arm 12 by approximately 90 °. One end face (lower side) of the leaf spring 62a also projects toward the sliding door 20b, and pushes the leaf spring 62b of the sliding door 20b. Then, the shaft 61b also rotates in the same direction to rotate the arm of the sliding door 20b, thereby rotating the handrail main body 11 by approximately 90 ° to the same side. When the handrail body 11 is returned, the handrail body 11 is rotated in the reverse direction and cooperates. It should be noted that both positions are equivalent, and if one of the handrail bodies 11 is put out, the other handrail body 11 is also put out.

Next, the handrail 70 for fittings shown in FIG.
The handrail 70a, which is provided on one side of the sliding door 71 of the fitting, for example, becomes available from the stored state, and the second handrail 70b provided on the opposite side of the sliding door 71 is automatically used from the stored state. The handrail is provided with handrail interlocking means on both sides of the fitting in a state, and is also provided with automatic driving means which automatically outputs the handrail when closed.
Two sets of the same automatic driving means as those shown in FIG. 9 are provided. That is, one shaft 31 (which does not rotate itself) is slid in the lateral direction by about 10 to 50 mm and is urged to the opening side (the right side in FIG. 16) by the spring 32 that is provided, and the sliding door 71 is opened. In this state, the tip 31b of the shaft 31 is 10 to 50 m from the side.
m. Four protruding members (cylindrical) 34 are provided at positions where the arms 72 and 73 of the shaft 31 are rotatably mounted on the shaft 31, and the shaft mounting portions 72 a of the arms 72 and 73 mounted on the shaft 31 are provided. A slit (or groove) 35 is provided on the 73a side obliquely with respect to the shaft axis, and is fitted with the projection member 34 on the shaft 31 side. Shaft attachment portions 72a, 73a of the arms 72, 73
When the protrusion member 34 slides along with the slide of the shaft 31 because the slide member itself does not slide, the slit (or groove) 35 fitted to the slide member is pushed by the protrusion member 34 to rotate around the axis of the shaft 31. Power is given. At this time, the direction of the slit (or groove) 35 is determined so that the rotation direction of the handrail main body 11b of the handrail 70b and the handrail main body 11a of the handrail 70a are opposite.
In FIG. 17, the arm 73 and the handrail body 11b intersect in the housed state, but it is important that the intersection is appropriately processed into a recess or the like so that the arm 73 can be housed. Of course, the shaft attachment portions 72a and 73a can be provided so as not to intersect. In addition, it is clear that the handrail for fittings provided with the automatic driving means and the handrail interlocking means on both sides of the fittings can be applied to a door (one door in FIG. 1 or a double door in FIG. 13) as it is.

Next, another embodiment of the handrail for fittings provided with automatic driving means and handrail interlocking means on both sides of the fitting is shown in FIG.

In the stored state, the handrail main body 11a fits on the upper side of the shaft 81, and the handrail main body 11b fits on the lower side. I have. Either handrail body 11a or handrail body 11b
When it is taken out and rotated 90 ° and slid sideways, it becomes usable, and the roots of the respective arms 82 and 83 hit against the cutting edge 89 of the fitting 88 in a horizontal state and are supported. When slid, the lock concave portion 87 provided on the shaft 81 is locked by being locked by the lock bar 86.
In the above-described embodiment, it is desirable to dispose the shielding plate 85 in order to close the storage portion of the handrail and keep the fitting airtight.

Although the embodiment of the handrail for fittings which can be stored in various kinds of fittings has been described above, it is ideal that the handrail for fittings of the present invention is completely stored in the fitting when not in use. Although there are some cases, there is no problem even if it slightly protrudes from the vertical surface of the fitting, so it is sufficient that most of the fitting is stored. In addition, in the case of the handrail for fittings of the present invention, the basic dimensions and shapes of the Western fittings and the Japanese fittings (the dimensions of which are generally determined) to be attached are determined in several types according to the opening width and the standing frame width of the fittings. Is preferred. For example, it corresponds to doors, one sliding door (single sliding door), two sliding doors, three sliding doors, and the like. In addition, the material of the handrail depends on the material of the fittings, steel handrails for steel doors, stainless steel handrails for stainless doors, aluminum for aluminum doors, wooden or synthetic resin (FRP etc.) for wooden doors ) Is preferable without giving a sense of incongruity. Further, it is preferable to incorporate the handrail for fittings in advance at the time of manufacturing the fittings, but it is also possible to partially cut out the ready-made fittings and fit them in later.

It should be noted that the handrail for fittings of the present invention described above can be applied not only to ordinary dwellings but also to all fittings in buildings, public facilities, and other buildings in which people may enter. It goes without saying that there is no doubt that it can be a very useful safety facility for the elderly and the disabled in realizing a human-friendly environment.
