  By the way, it is common that old houses that have been used to living by elderly people who need handrails for sliding doors have become obsolete, such as several decades after construction. There were various problems when trying to apply to the sliding doors of generalized houses. That is, distortion, deformation, wear, etc. of an aging house, the central part of the sill is lowered downward (or conversely the central part of the sill is raised upward), the sliding door is tilted, Sliding doors are spaced in the thickness direction, and bending force is applied to the conventional sliding door handrails that are installed, and the sliding door handrails inserted in a slidable nesting shape are smooth. The sliding doors were awkward and inconvenient for the elderly and those who had difficulty with their legs and legs and had weak hands and arms. In addition, it is a sliding door of a house built in an era when there was no unified building standard in the past, it is a sliding door of a unique house type in the region, and the thickness of the sliding door in the same house is also different I did. Therefore, many kinds of assortment of goods are necessary for the sliding door handrail, and it has become an expensive sliding door handrail.

  This will be described with reference to the drawings. FIG. 10 is a plan view (partially broken) in which a sliding door handrail is attached to a conventional sliding sliding door. FIG. 11 shows a front view corresponding to the plan view of FIG. The sliding door 21 is disposed between the sill 34 and the duck 35 in the opening 33 of the side wall 32 at the boundary between the hallway 30 and the room 31, and the sliding door handrail 1 is attached to the sliding door 21. The sliding sliding door 21 includes the first sliding door 22 on the corridor 30 side and the second sliding door 23 on the indoor 31 side. One first handrail 2 is attached to and held by the first sliding door 22, and the other second handrail 3 is attached and held by the second sliding door 23. The sliding door handrail 1 has a telescoping type that allows the other second handrail 3 to be fitted into the one first handrail 2 and be relatively slidable.

The one first handrail 2 of the handrail 1 for the sliding door is connected to the first sliding door 22 on the side of the hallway 30 by the first support member 84 at one end on the right side, and the other end on the left side. Are respectively attached and held by the second support member 85. Then, the other end on the left side of the other second handrail 3 is attached to the left surface (the surface facing the hallway 30 side) of the second sliding door 23 on the indoor 31 side by the third support member 86. Is retained. Furthermore, the one end of the right side of the other second handrail 3 is formed in a hollow cylindrical (pipe-like) first side of the first handrail 2 from the other end on the left side. The first sliding door 22 is inserted into the handrail 2 in a slidable manner so as to be slidable, and the second supporting member 85 passes through the outer peripheral portion of the other left end portion of the first handrail 2. That is, it is held horizontally on the surface of the left end (the surface facing the hallway 30 side).

  Referring to FIG. 11, when the central portion of the sill 34 is lowered downward due to distortion or deformation of an aging house as described above, the handrail member shaft center of the sliding door handrail 1 is The upper surface of the sill 34 (the upper surface of the sill 34 in FIG. 11 may be the upper surface of the first guide rail or first sill groove 34A, or the second guide rail or second sill groove 34B). Think about the distance. That is, the distance from the center of the handrail member axis of the sliding door handrail 1 to the upper surface of the sill 34 on the right side (right side wall 32 side) and the left side (left side wall 32 side) of the sliding sliding door 21. Is the sum of the sliding sliding door 21 (the central portion where the edges of the sliding sliding door 21 in the closed state overlap each other) and the sill 34 The distance to the upper surface is H + h (h is the lowering amount of the central portion of the sill 34 (or the rising amount, where h is a negative value)). In other words, due to aging, the sill 34 is in a central concave state (or a central convex state), and the first sliding door 22 and the second sliding door 23 constituting the sliding sliding door 21 are substantially in katakana. Inclination occurs in the C-shape (or the reverse C-shape of a substantially katakana).

  That is, the first sliding door 22 and the second sliding door 23 constituting the sliding sliding door 21 are inclined in a substantially katakana-shaped shape (or a reverse-shaped shape of a substantially katakana), and the sliding door handrail 1 When the sliding door 21 is simply mechanically attached to the sliding sliding door 21 such that the distance from the center of the handrail member axis to the upper surface of the sill 34 is H, the first support The member 84, the second support member 85, and the third support member 86 are attached in the horizontal direction. A bending force acts on the handrail 1 for sliding door in a concave (or convex upward) downward. As a result, the sliding door handrail 1 attached to the sliding sliding door 21 at the position of the dimension H from below is such that the central portion in the left-right longitudinal direction is bent downward (or upwardly convex) ( Deformation force (due to the weight and frictional force of the first sliding door 22 and the second sliding door 23) is applied. For this reason, the sliding door handrail 1 inserted in a slidable telescopic manner is not smooth, and the sliding doors of the elderly and those who have difficulty with the legs and hips and have weak hands and arms can be used. Opening and closing was awkward and inconvenient.

  In addition, when the conventional sliding door for the sliding door 1 is adopted and attached to the sliding sliding door 21, the same kind of sliding door or shoji, the thickness of the sliding door varies from region to region in Japan, and even in the same region For example, there are many types of sliding doors, such as sliding doors, clear doors, and sliding doors that open and close cabinets such as footwear boxes, and there is no standard for each sliding door. As described above, the sliding sliding door 21 is disposed in the opening 33 of the side wall 32 at the boundary between the corridor 30 and the indoor 31, and the sliding door 21 is attached with the sliding door handrail 1. The distance W1 from the handrail member axis center of the handrail 1 to the surface of the first sliding door 22, and the distance W2 from the handrail member axis center of the sliding door handrail 1 to the surface of the second sliding door 23, Relationship like Consider, that is, W2-W1 = (sliding doors thickness W + first, the gap amount between the second sliding door w). Here, the gap amount w between the first and second sliding doors is approximately constant at about 1 to 3 millimeters, but there was no unified standard for the thickness of the sliding doors before the Japanese Industrial Standards existed, The sliding door thickness W was not constant. Thus, in order to attach the conventional sliding door handrail 1 to the sliding sliding door 21, in order to ensure the dimension of (W + w) in consideration of the sliding door thickness W, a third suitable for this is provided. The supporting member 86 must be prepared, which is inconvenient due to high costs. The present invention has been made to solve these drawbacks.

  According to claim 1, in the sliding door rail which is nested by inserting the other second rail into one of the first rails, the horizontal rail is supported so that the sliding door rail held in the horizontal direction can be translated in the vertical direction. It is a handrail for sliding doors including a member. Of course, the handrail for sliding doors of the present invention may be adopted in a new house, but may also be adopted in a general house which is aged. When the telescoping handrail is attached to an old sliding door or sliding sliding door, the left and right ends of the sliding door rail and the vicinity of the middle part of the sliding door or sliding sliding door Three points are supported in the horizontal direction by the support member, and are attached to the sliding door and the sliding sliding door. Due to aging, the middle part of the sill is deformed upward (or downward). Since the sliding door disposed on the sill is inclined, the sliding door handrail mechanically attached to the support member from the lower side of the sliding door to the position of the dimension H is recessed downward in the center in the left-right longitudinal direction of the sill. A deforming force to be bent is applied to the (H + h) dimension in the state (or the (H-h) dimension in the upward convex state). At this time, the support member at the intermediate point at the three-point support near the summoning of the sliding door and the sliding sliding door is configured to be movable in either the upper or lower direction, and the sliding door handrail 1 is The intermediate support point can be translated in either the up or down direction to maintain linearity. For this reason, the operation of the sliding sliding handrail inserted in a relatively slidable manner is kept smooth, and the sliding door with the sliding door handrail and the sliding sliding door can be opened and closed smoothly and lightly, It is also safe and convenient for elderly people and those who have difficulty in walking with legs and weak hands and arms.

  Further, in the supporting member of the intermediate supporting point that can be translated in the vertical direction according to the present invention of claim 1, the sliding member for the sliding door is provided by a channel member having a substantially inverted C-shaped section guided by a substantially inverted T-shaped projecting section. Even if a force is applied to the support member, such as when a person is grabbing on the channel member, the channel member abuts against the rectangular parallelepiped member, and the descent is prevented and kept below a certain size. It is also convenient and safe for pedestrians because the sliding doors and sliding sliding doors can be opened and closed smoothly and lightly.

  In the second aspect of the sliding door handrail in which the second handrail of the other is inserted into the first handrail of one type to make a nesting type, the handrail for the sliding door held in the horizontal direction is translated in the thickness direction of the sliding door. It is a handrail for sliding doors including a support member. In the present invention, in a newly built house or house, this sliding door handrail may be adopted as a sliding door or a sliding door. Even if the thickness of the sliding door is different, even if the sliding door is different in the same house, the sliding rail for the sliding door held in the horizontal direction is translated in the thickness direction of the sliding door. The distance W1 from the handrail member axis center of the sliding door handrail to the surface of the first sliding door (the surface of the mounting wall in the case of a single sliding door), and the second from the handrail member axis center of the sliding door handrail, The gap between the first and second sliding doors in the relational expression of W2−W1 = (the sliding door thickness W + the gap amount w between the first and second sliding doors) in relation to the distance W2 to the surface of the sliding door. The amount w is about 1 to 3 millimeters and is almost constant, and the sliding door thickness W Change. Even if it is such a sliding door, what is necessary is just a support member which can translate the sliding door handrail in the thickness direction of a sliding door. Therefore, even if the thickness of the sliding door changes in this way, if you prepare one type of support member that can be translated in the thickness direction of the sliding door, a sliding door handrail is attached to many types of sliding doors and sliding sliding doors. It is possible, and special adjustment work such as inserting a shim (shim) is not required at the time of installation, the handling is easy, and an inexpensive sliding door handrail can be supplied.

According to the present invention, since the bearing member for reducing the frictional resistance is provided on the inner surface of the opening of one of the first handrails, the sliding between the other second handrail outer surface and the one first handrail inner surface is provided. The sliding resistance of the sliding door, which is inserted in a slidable manner so that the frictional resistance of the sliding part is reduced, is smooth, and the elderly and those who have difficulty with the legs and hips and have weak hands and arms Therefore, the sliding door and the sliding sliding door to which the handrail for the sliding door is attached are useful for assisting when walking and opening and closing the sliding door and the sliding sliding door smoothly and lightly.

  In claim 4, a pair of sliding sliding doors arranged opposite to each other, a sliding rail for a sliding door, in which the other railing is inserted into one railing and opposite to each other, is attached horizontally and summoned. The sliding door handrail is provided with a supporting member provided with a structure for preventing the other handrail from slipping out and fitted into the one handrail, while the sliding door handrail can be moved in an up and down direction at an intermediate portion.

  According to the fourth aspect of the present invention, a sliding sliding door provided with a sliding door handrail attached to a shoji screen or a light shoji facing a particularly long corridor can be provided. When the telescoping sliding door is attached to a sliding door or sliding door of an aged house, the features of claims 1, 2, and 3 are provided. That is, as in claim 1, the sliding door provided with the sliding door handrail held in the horizontal direction by the three-point support between both ends and the middle is upward (or downward) due to distortion of the house, deformation of the sill, etc. In the sliding door handrail that is mechanically attached to the H dimension position from below, the intermediate support point in the left and right longitudinal direction of the sill is recessed downward (H + h) (or upwardly protruding (H -When the deformation force that bends to dimension (h) is applied, the support member at the intermediate portion can be translated in either the upper or lower direction so that the sliding doorrail can maintain linearity, The intermediate support part of the sliding door handrail is moved in parallel. A force is applied to the support member when a person grabs and leans on the sliding door handrail by a channel member having a substantially C-shaped cross section guided by a substantially inverted T-shaped projecting portion capable of translating. However, since the channel member abuts on the rectangular parallelepiped member and prevents the channel member from descending and being held below a certain size, deformation of the sliding door handrail can be prevented. For this reason, the operation of the sliding sliding handrail inserted in a relatively slidable manner is kept smooth, and the sliding door and the sliding sliding door facing the long corridor where the sliding door handrail is attached can also be opened and closed. It can be opened and closed smoothly, and it is safe and convenient for the elderly and for those who have difficulty in walking, and have weak hands and arms.

  Further, in claim 4, as in claim 2, a support member that can translate the sliding door handrail attached to the shoji and light shoji facing the particularly long corridor in the thickness direction of the sliding door is adopted. Even if the thickness of the sliding door changes, if you prepare one type of support member that can be translated in the thickness direction of the sliding door, you can attach a sliding door handrail to many types of sliding doors and sliding sliding doors. There is no need for special adjustment work such as inserting a shim (shim) at times, handling is easy, and an inexpensive sliding handrail can be supplied. For pedestrians, the sliding doors and sliding doors facing the long corridor can be opened and closed smoothly and lightly, allowing elderly people and people with disabilities to walk safely while holding the long corridor on the handrail. It is convenient.

  Further, in the fourth aspect, as in the third aspect, in the sliding door handrail in which the other second handrail is inserted into one first handrail to form a telescoping type, the other second handrail is inserted. This is a sliding door handrail in which a bearing member is provided in the opening of one of the first handrails. According to the present invention, since the bearing member for reducing the frictional resistance is provided on the inner surface of the opening of one of the first handrails, the sliding between the other second handrail outer surface and the one first handrail inner surface is provided. The sliding resistance of the sliding door, which is inserted in a slidable manner so that the frictional resistance of the sliding part is reduced, is smooth, and the elderly and those who have difficulty with the legs and hips and have weak hands and arms Therefore, the sliding door and the sliding sliding door to which the handrail for the sliding door is attached are useful for assisting when walking and opening and closing the sliding door and the sliding sliding door smoothly and lightly.

  In the fourth aspect, as described above, the third aspect of the present invention has the features of the first, second, and third aspects. A fourth support member provided with a structure for preventing the sliding of the other handrail to be fitted into the one handrail and capable of moving the handrail for the sliding door in the vertical direction at an intermediate portion near the summoning of the sliding door. It is a handrail for sliding doors. A set screw is provided in the fourth support member body of the fourth support member, a screw hole in the fourth bush, a hole provided in the vicinity of the left other end of the third handrail, and a groove provided in the fourth handrail. And the fourth handrail is prevented from coming out of the hollow tubular third handrail. This eliminates the need for troublesome assembly work when the mating state is released, and even if elderly people or people with disabilities in the limbs grab or lean on the long corridor facing the shoji and light shoji, Since the structure for preventing the fourth handrail from slipping into the third handrail is formed, it is possible to prevent the other fourth handrail from coming out of one third handrail and hold it in the sliding door handrail. You can walk safely. Of course, since the handrail for the sliding door can be attached not only to the hallway side but also to the indoor side of the sliding door, it is possible to walk safely in the room.

  Further, in the fourth aspect of the present invention, as the fourth embodiment of the present invention, the structure for preventing the other handrail from slipping into the one handrail is arranged so as to face the sliding door end surface portion near the summoning of the sliding door. When the first stopper member 64 and the second stopper member 65 are attached and the sliding sliding doors 21 and 66 are closed, the sliding sliding door 21 has a space between the first and second sliding doors 22 and 23. In the sliding door 26, the protrusions 64A and 65A of the first stopper member 64 and the second stopper member 65 are in contact with each other so that the fifth and sixth sliding doors 67 and 68 are not separated from each other. The restrictor is formed, and a structure for preventing the other handrail from slipping into the one handrail is formed.

  According to the handrail for sliding doors of the present invention, it may be adopted for a newly built house, or for an old house such as several decades that has been used for many years by elderly people who need a handrail for sliding doors. It may be adopted. When a telescoping handrail is attached to a sliding door or sliding door, even if the sliding handrail held in the horizontal direction changes upward (or downward) due to housing distortion, sill deformation, etc. Here, the sliding door handrail is provided with a support member capable of moving in parallel in the vertical direction, and the sliding door handrail mechanically attached to the sliding door from the lower side to the H dimension position has a central portion in the left and right longitudinal direction of the sill below. Deformation force to bend is added to the concave (H + h) dimension (or conversely, the upward convex (Hh) dimension). At this time, the support member is translated in either the upper or lower direction so that the sliding door rail 1 maintains linearity. For this reason, the operation of the sliding sliding handrail inserted in a relatively slidable manner is kept smooth, and the sliding door with the sliding door handrail and the sliding sliding door can be opened and closed smoothly and lightly, Sliding doors with sliding door rails and sliding doors can be opened and closed smoothly and lightly for elderly people and those with weak legs and weak hands and arms.

As a result, even if the sliding door rail 1 extending to the left is rotated in the vertical direction, the right end of the sliding door rail 1 is supported by the first support member 4 in the first direction. Although it corresponds to be rotatable on the right side of the one sliding door 22, it is securely attached and supported. (See Figs. 1 and 2)

  That is, the sliding door handrail 1 extending to the left of the first support member 4 may be lowered in accordance with the tilting or vertical movement of the sliding door 21 due to the deformation of the sill 34 or the like. When the sliding door handrail 1 moves upward, the first support member 4 can be rotated to cope with it, and a pedestrian grabs or leans on the sliding door handrail 1 to apply force. Also, the right end of the sliding door handrail 1 is securely attached and held by the first support member 4. Of course, at the time of assembly, the first support member 4 is first attached to the right surface of the first sliding door 22 with the attachment screws 8, 8, and then the one first handrail 2 is attached. A right end may be inserted into the first support member body 6 and attached with the set screw 7. To remove the sliding door handrail 1, the set screw 7 may be removed.

  Next, FIG. 3 shows an exploded perspective view of the second support member 11 according to the present invention. The second support member 11 that is attached to the left surface of the first sliding door 22 and supports the intermediate portion of the sliding door handrail 1 in the middle portion of the sliding sliding door 1 near the summons will be described. With reference to FIGS. 1 and 3, the second support member 11 includes a second support member main body 12 and a second mounting plate 13. The second support member main body 12 has a second bush 12A and a second projecting member 12B fixed in a substantially inverted T shape, and further on the distal end surface on the other side of the second projecting member 12B. A channel member 12C having a substantially inverted C-shaped cross section is fixed. The material of the second support member main body 12 can be made of metal, synthetic resin, or wood.

  The second mounting plate 13 has a substantially inverted T-shaped projecting portion 13B having a transverse cross section in the middle of the second mounting plate main body 13A, and a rectangular parallelepiped member 13C fixed thereto in contact therewith. . Further, a pair of mounting holes 13D, 13D are provided in the vicinity of the upper and lower ends of the second mounting plate main body 13A, and are attached to the left surface of the first sliding door 23 with set screws 14, 14. The channel member 12C having a substantially inverted C-shaped cross section of the second support member main body 12 is fitted into the substantially inverted T-shaped projecting portion 13B of the second mounting plate 13 and is moved and guided in the vertical direction. The rectangular parallelepiped member that is in contact with the substantially inverted T-shaped projecting portion 13B and is fixed to the lower side when a downward force (such as a pedestrian grabs and leans) is applied to the second support member main body 12 and descends. The lowering of the second support member main body 12 stops by contacting 13C.

  This means that in the support member 11 that can be moved in the vertical direction, even when a pedestrian grabs and leans against the sliding door handrail 1, the channel member 12C is Since it abuts on the rectangular parallelepiped member 13C to prevent the descent and keep it below a certain size, deformation of the sliding door handrail 1 can be prevented. As a result, even if a pedestrian grabs and leans on the sliding door rail 1, the sliding door rail 1 does not drop and deform more than a certain size, so that it can be smoothly expanded and contracted, and the sliding door rail 1 is attached. The sliding sliding door 21 can be opened and closed smoothly so that a pedestrian can easily open and close the sliding sliding door 21. Even if the sliding sliding door 21 is caught by the handrail 41, the sliding sliding door 21 can be helped when walking. is there.

  Further, in the second support member 11, the transverse section substantially inverted C-shaped of the second support member body 12 is formed on the substantially inverted T-shaped projecting portion 13 B which is fixed to the second mounting plate 13. Since the channel-shaped channel member 12C can be inserted and guided in the up-and-down direction, the aging general house is distorted, deformed or worn, or the central part of the sill is lowered downward (or vice versa). The central part of the sill is raised upward) and the sliding door or the sliding sliding door is tilted, that is, for example, in the sliding sliding door 21 specifically, the first sliding door 22 and the second sliding door 23 Even if they are tilted so as to fall into Katakana's half-shaped shape (or even if they are tilted so as to fall into Katakana's reverse-half-shaped shape), the sliding door handrail 1 is summoned for the sliding sliding door 21. Matching part ( The second support member main body 12 of the second support member 11 near the center portion where the edges of the sliding sliding door 21 in the chain state meet and overlap each other is slidably guided downward (or the first Second support member main body 12 is slid and guided upward), the first rail or the first sill groove 34A from the center of the handrail member axis of the handrail 1 for the sliding door near the summing portion of the sliding sliding door 21. Alternatively, the distance to the upper surface of the second rail or the second sill groove 34B is H + h (h is a positive value in the lowering amount of the central portion when the sill 34 is recessed downward, and conversely h is When the sill 34 is convex upward, the amount of increase is a negative value (see FIG. 11), but also when the sill 34 bends downward (so-called slack) (or On the other hand, even in the case of bending upward in the convex state), the second The channel member 12C having a substantially inverted C-shaped cross section of the holding member main body 12 is inserted and guided in the vertical direction, and automatically moves to the upper (or lower) change amount to correct the correspondence. The handrail member shaft center of the handrail 1 is held on the same straight line without being forced to be arranged on the same line, and the bending of the sliding door handrail 1 attached to the sliding sliding door 21 is held. The sliding sliding door 21 can be opened and closed smoothly because it slides smoothly and freely without deformation force.

  Further, the rectangular parallelepiped member 13C serves as a limiter (stopper) for the downward movement of the second support member main body 12. That is, the second support member 11 prevents the sliding door handrail 1 from descending further even if a pedestrian grips and leans against the sliding door handrail 1, and serves as a limiter (stopper). Therefore, the sliding door rail 1 can be prevented from being deformed due to excessive lowering, and the safety of the pedestrian can be ensured.

  Then, the other end on the left side of the one first handrail 2 having a hollow cylindrical shape is inserted into the second bush 12 </ b> A of the second support member main body 12. Then, the inner diameter of the opening 2A at the other end on the left side of one of the first handrails 2 in the hollow cylindrical shape (pipe shape) is expanded (cutting or mechanical expansion may be performed), and the expanded inner diameter A bush (bearing member) 2B having a small friction coefficient is provided in the part. The bush (bearing member) 2B may be a sliding bearing made of synthetic resin such as nylon, polyimide, polyethylene, or tetrafluoroethylene resin, or may be a sliding bearing using graphite or molybdenum disulfide, or other rolling elements. A bearing may be used. The inside of the bush (bearing member) 2B provided in the opening 2A at the other end on the left side of the one first handrail 2 in the hollow cylindrical shape (pipe shape) The second handrail 3 is smoothly guided to slide. Thus, the sliding sliding door 21 that moves in parallel with the sliding door handrail 1 can be smoothly opened and closed.

  The second support member 11 is attached to the left surface of the first sliding door 22 using set screws 14 and 14 in a pair of upper and lower attachment holes 13D and 13D. Then, the other end on the left side of the first handrail 2 having a hollow cylindrical shape (pipe shape) is inserted into the second bush 12A, and further, the first handrail having a hollow cylindrical shape (pipe shape). The sliding door rail 1 is nested by inserting the right end portion of the rod-shaped second handrail 3 into the bush (bearing member) 2B of the enlarged inner diameter portion of the opening 2A at the left other end portion of 2. The intermediate portion is held by the second support member 11. The sliding door handrail 1 can be removed by removing the set screw 14.

  Next, FIG. 4 shows an exploded perspective view of the third support member 17 according to the present invention. The third support member 17 includes a third support member main body 18 and a third attachment plate 19. The third support member main body 18 has a third bush 18A and a pipe-like third projecting member 18B fixed in an inverted T shape, and is near the left end of the third bush 18A. Is provided with a screw hole 18C on the side surface in the vicinity of the tip of the third projecting member 18B. The third mounting plate 19 includes a third mounting plate main body 19A and a projecting bar member 19B protruding from the center of the third mounting plate main body 19A, and the third mounting plate main body 19A. A pair of mounting holes 19D and 19D are provided in the vicinity of the upper and lower ends.

  A groove portion 19C is formed on the side surface of the protruding rod member 19B, and the groove portion 19C is formed at a position corresponding to the screw hole 18D on the side surface in the vicinity of the tip of the third protruding member 18B. Yes. Then, the protruding rod member 19B is fitted inside the pipe-shaped third protruding member 18B, and the mounting screw 20B is screwed into the screw hole 18D, so that the tip thereof faces the groove 19C. Installed. As a result, the third projecting member 18B is guided by a groove 19C in which the tip of the mounting screw 20B is carved on the side surface of the projecting bar member 19B, and the third support member main body 18 is supported by the projecting bar. Guided by the member 19B, its axial translation is possible, and the tip of the mounting screw 20B is fitted in the groove 19C so that it does not separate without being removed. Guide the translation. Thus, the sliding door handrail 21 can be translated in the thickness direction of the sliding door. By the way, as a means for adjusting the thickness direction, a thin sheet metal shim can be used. However, the number of sheets used is not constant, and adjustment work is added, which is inconvenient.

  Then, the other end on the left side of the other rod-shaped second handrail 3 is inserted into the third bush 18 </ b> A of the third support member main body 18. Then, a screw 20A is screwed into the screw hole 18C and a stop hole 3A provided in the vicinity of the other end on the left side of the other rod-shaped second handrail 3, whereby the left side of the sliding door handrail 1 is secured. The end portion can be held in the horizontal direction on the third support member 17. In this case, of course, the third mounting plate 19 is screwed to the left surface of the other second sliding door 23 by means of a pair of mounting holes 19D, 19D using mounting screws 2OC, 20C. It is. Accordingly, in the third support member 17, the third projecting member 18B and the projecting bar member 19B can be moved relatively in parallel to each other, the left side of the sliding door handrail 1 held in the horizontal direction. It means that the end can be translated in the thickness direction of the sliding door. That is, the third support member 17 can cope with various sliding door thicknesses when there was no unified standard, and the sliding door handrail 1 can be easily used for various thickness sliding doors and sliding sliding doors. It can be applied. Accordingly, the sliding door handrail 1 according to the present invention is held in the horizontal direction by the third support member 17, and the left end portion of the sliding door handrail 1 is moved to the sliding door by only one kind of the third support member 17. It can be translated in the direction suitable for the thickness, and adjustment is not required, the cost is low, installation is easy, and it can be applied to various kinds of sliding doors and sliding sliding doors.

  The first support member 4 can be easily attached to and detached from the sliding door handrail of the present invention by attaching and detaching the set screw 7 and the set screw 8. The second support member 11 can also be easily attached / detached with the set screw 14. In the 3rd support member 17, it can carry out easily by attachment or detachment of mounting screw 20A, 2OB, 20C.

  FIG. 5 is an exploded perspective view showing a second embodiment according to the present invention. The second sliding door 23 guided on the second rail (or second sill groove) 34B is disposed in the opening 33 between the left column 32B and the intermediate column 32C at the left end of the sill 34, and further A wall member 29 provided between the intermediate column 32C and the right column 32A at the right end is disposed. And, for the telescopic sliding door, between the left surface of the second sliding door 23 guided on the second rail (or second sill groove) 34B and the right column 32A at the right end. A handrail 1 is attached.

  The second embodiment of the present invention of FIG. 5 is similar to that of FIG. 1, but there are significant differences as will be described later. In FIG. 5, the right end of the sliding door handrail 1 is supported by the first support member 4 attached to the surface of the right column 32A, and the sliding door handrail 1 is the first supporting member. The left side of the sliding door handrail 1 is rotatably supported around the member 4. In the closed state of the second sliding door 23, the other left end portion of the second handrail 3 in the form of a rod is attached and held on the left surface of the second sliding door 23 by the third support member 17. Has been. Then, one end of the rod-shaped second handrail 3 on the right side is fitted into the opening 2A at the other end on the left side of the first handrail 2 in the shape of a hollow tube (pipe). Has been. Then, the inside of the bush (bearing member) 2B provided in the opening 2A at the other end on the left side of the first handrail 2 of the hollow cylindrical shape (pipe shape) is the other of the rod shape. The second handrail 3 is smoothly slid and guided. Thus, the second sliding door 23 that moves simultaneously with the other second handrail 3 in the bar shape of the sliding door handrail 1 can be smoothly opened and closed.

  The outer surface of the opening 2A is supported by the second support member 11 attached to the surface of the intermediate column 32C. The other end of the left side of the other second handrail 3 in the shape of a bar is held in the horizontal direction by the third support member 17 attached to the left surface of the second sliding door 23. That is, as described above, the handrail 1 for the sliding door is horizontally moved by the first support member 4, the middle portion by the second support member 11, and the left by the third support member 17. Will be held. The mounting surface of the support member 4 is the surface of the right column 32A, and the mounting surface of the support member 11 is the surface of the intermediate column 32C. A plane including the surface of the right column 32A and the surface of the intermediate column 32C can be expressed as a “mounting wall surface” as a common mounting surface.

  The second embodiment of the present invention shown in FIG. 5 is significantly different from that shown in FIG. 1 in that the mounting surfaces of the first and second support members 4 and 11 shown in FIG. The distance from the “wall surface” to the surface of the second sliding door 23 which is the mounting surface of the third support member 17 is the mounting surface of the first and second support members 4 and 11 in FIG. This corresponds to the distance from the surface of the first sliding door 22 to the surface of the second sliding door 23. For this reason, the distance from the “mounting wall surface” in FIG. 5 to the surface of the second sliding door 23 (because the thickness of the pillar is larger), the distance from the surface of the first sliding door 22 in FIG. This is overwhelmingly larger than the distance to the surface of the second sliding door 23. Therefore, in the third support member 17, the function that the third projecting member 18B and the projecting bar member 19B can move relative to each other is exhibited to the maximum, and the sliding door is held in the horizontal direction. Since the left end of the handrail 1 is translated in the thickness direction of the sliding door, the sliding door handrail 1 is supported by the third support member 17 straight without being bent, so that the sliding door handrail 1 is smooth. Since it can slide, the second sliding door 23 can be opened and closed smoothly. Therefore, even if the distance from the “mounting wall surface” in FIG. 5 to the surface of the second sliding door 23 changes greatly, one type of the supporting member 17 that can be moved in the thickness direction of the sliding door is prepared. The handling is easy, and an inexpensive handrail for sliding doors can be supplied.

  Further, due to distortion and deflection of the sill 34 due to an aging house or the like, it is supported by the third support member 17 on the left side surface of the second sliding door 23 at the left other end of the sliding door handrail 1. Compared with the positions supported by the first and second support members 11 and 4 at the location of the intermediate column 30 and the right column 32A on the near side (the “mounting wall surface”). The second mounting plate is also attached to the channel member 12C having a substantially C-shaped cross section of the second support member main body 12 of the support member 11 even in a state where it is relatively displaced upward or on the contrary. A substantially inverted T-shaped projecting portion 13B of the main body 13A is fitted, is guided to move in the vertical direction, automatically moves to the upper (or lower) change amount, and at the same time is corrected for the sliding door. The right end of the handrail 1 is the right column The sliding door handrail 1 is supported by the first support member 4 attached to 2A, in the countersink hole 5A from the back surface of the first attachment plate 5 in the first support member 4. A stepped screw 6E is inserted and screwed into the screw hole 6D, and the left side of the sliding door handrail 1 is rotatably supported by the countersink hole 5A and the stepped portion of the stepped screw 6E. Therefore, the handrail member axis center of the sliding door handrail 1 is not stretched so as to be forcibly arranged on the same line, and the bending of the sliding door handrail 1 supported by the sliding sliding door 21 is bent. Therefore, the center of the handrail member axis of the first handrail 2 and the center of the handrail member axis of the second handrail 3 are always arranged on the same straight line. The other second handrail 3 is inserted into the handrail 2 Expansion and contraction of the sliding door handrail 1 having a lever type is performed smoothly. That is, the second sliding door 23 to which the sliding door handrail 1 is attached can be opened and closed smoothly.

  As described above, when the channel member 12C guided by the substantially inverted T-shaped projecting portion 13B is guided to the second support portion 11 and a person is caught on the first handrail 1, the second support portion 11 is Even if a force is applied to the second support member 11, the first handrail 1 can prevent the first handrail 1 from being deformed because the channel member 12C abuts against the rectangular parallelepiped member 13C to prevent the first handrail 1 from descending. The rectangular parallelepiped member 13C serves as a limiter (stopper) for the downward movement of the second support member main body 12. That is, even if a pedestrian grabs and leans on the sliding door handrail 1 attached to the second sliding door 23, the sliding door handrail 1 is prevented from further descending downward, and a restrictor (stopper). Therefore, the first handrail 1 can be prevented from being deformed due to excessive lowering, and the safety of the pedestrian can be ensured.

  Furthermore, even when the third support member 17 exerts a force in a direction in which the intermediate column 32C and the right column 28 and the second sliding door 23 are separated from each other for reasons such as aging of the building itself, Since the pipe member 18B and the bar member 19B can be relatively translated and can absorb the displacement, the second sliding door 26 can be opened and closed smoothly.

  Next, FIG. 6 shows a perspective view of a third embodiment of the present invention. According to FIG. 6, the sliding door 21 is placed on the left half and the sliding door 21 is pulled on the right half, opposite to the openings 33 (not shown) between the pillars 32B and 32A provided on the left and right ends of the sill 34. The sliding door 61 is disposed symmetrically. The sliding sliding door 21 has a first sliding door 22 on the front side and a second sliding door 23 on the rear side. Similarly, the sliding sliding door 61 is configured with a third sliding door 62 on the front side and a fourth sliding door 63 on the rear side. Then, the first sliding door 22 and the third sliding door 62 are guided on the first rail (or sill groove) 34A, and the second rail (or sill groove) 34B (not shown). On the top, the second sliding door 23 and the fourth sliding door 63 are guided.

  In the sliding sliding door 21 and the sliding sliding door 61, a sliding-type sliding door is formed by inserting a rod-shaped fourth handrail 43 into one hollow cylindrical (pipe-shaped) third handrail 42. The handrails 41 are formed and symmetrically attached to each other in the horizontal direction. First, the sliding sliding door 21 side will be described. The sliding sliding door 61 side will be described later. In the left half of the opening 33 (not shown), on the right surface of the first sliding door 22 that forms the sliding sliding door 21, the right side of one third handrail 42 in the shape of a hollow cylinder (pipe). One end is provided by the first support member 4 and on the left surface of the first sliding door 22. An end is held horizontally by the fourth support member 51, and the other left end of the rod-shaped fourth handrail 43 is formed on the left surface of the second sliding door 23. The other end of the fourth handrail 43 in the form of a rod that is held horizontally by the support member 17 and the left end of the third handrail 42 in the shape of a hollow cylinder (pipe-shaped) near the summit. It is inserted into the opening 42A at the end (not shown in FIG. 6, see FIG. 8) and is held horizontally in a telescopic manner in a telescopic manner. In this manner, an intermediate portion of the sliding door handrail 41 described later can be translated in the vertical direction by the fourth support portion 51 and the other fourth handrail that fits into the third handrail 42 is inserted. It has a structure for preventing the handrail 43 from coming off, and is held horizontally by a support member 51 by a bush (bearing member) 42B, and is attached smoothly and slidably.

  Next, the sliding sliding door 61 will be described symmetrically (see FIG. 6). On the left half surface of the third sliding door 62 that forms a sliding sliding door 61 in the right half of the opening 33 (not shown), one left end of the third handrail 42 having a hollow cylindrical shape (pipe shape) is provided. The right other end of the one third handrail 42 in the shape of a hollow cylinder (pipe-shaped) near the summit is formed on the right surface of the third sliding door 62 by the first support member 4. Is held horizontally by the fourth support member 51, and the other right end of the rod-shaped fourth handrail 43 is disposed on the right surface of the fourth sliding door 63. The other end on the right side of the one third handrail 42 in the shape of a hollow cylinder (pipe shape) near the summit is held on the left side of the other rod-like fourth handrail 43 held horizontally by the member 17. It is inserted into an opening 42A (not shown) of the part and is held horizontally horizontally in a telescopic manner. In this way, as will be described later, the middle portion of the sliding door handrail 41 provided in the opposite horizontal direction can be translated in the vertical direction by the fourth support member 51, and the one third The other fourth handrail 43 fitted into the handrail 42 has a structure for preventing the other handrail 43 from slipping out, and is held horizontally by a support member 51 via a bush (bearing member) 42B, and is attached smoothly and slidably. ing.

  In FIG. 6, the configuration of the sliding sliding door 21 provided with the sliding door handrail 41 on the left half of the opening 33 (not shown) is the same as that for the sliding door on the right half of the opening 33 (not shown). It is symmetrical with the configuration of the sliding sliding door 61 to which the handrail 41 is attached, just opposite 180 degrees. Thus, in the right half, the left sliding door 21 is replaced with the right sliding door 61, the left first sliding door 22 is replaced with the right third sliding door 62, and the left second sliding door 23 is replaced with the right sliding door 61. The fourth sliding door 63 is replaced with a hollow cylindrical (pipe-shaped) third handrail 42 with a rod-shaped fourth handrail 43 fitted therein, and the sliding door handrail 41 is 180 degrees on the right side. The sliding door handrail 41 is formed in the opposite direction. If the left half of the opening 32 (not shown) is described, the description of the right half can be omitted because it can be read as described above.

  In FIG. 6, the sliding door handrail 41 attached to the sliding door 21 on the left half of the opening 33 (not shown) is the sliding door 21 according to the first embodiment of the present invention shown in FIG. The difference between the sliding door handrail 1 attached to the sliding door is that, when the sliding sliding door 21 in FIG. It is. However, since the sill 34 is long in the sliding sliding door 21 of FIG. 6, the first sliding door can move away from the second sliding door 23 and move to the right of the opening 33 (not shown). In this case, the rod-shaped fourth handrail 43 is fitted into the one third handrail 42 having a hollow cylindrical shape (pipe shape) attached to the sliding sliding door 21 so as to be nested. The sliding door handrail 41 can be manufactured at low cost if there is no structure for preventing the detachment of the nesting part. The handrail 43 is removed, and the sliding door handrail 41 is disassembled, so that the handrail function is lost, which is inconvenient. In order to prevent this, the third embodiment of the present invention shown in FIG. 6 is implemented. That is, in the support member 51 according to the third embodiment of the present invention as shown in FIGS. 7 and 8, in addition to the vertically movable structure, the sliding portion of the sliding door handrail 41 can be removed. A prevention structure may be provided.

  In addition, as will be described later, as shown in FIG. 9, as a fifth embodiment of the present invention, a sliding prevention structure for the telescopic part of the sliding door handrail 1 is provided on the door side, and is fitted into the one handrail. A first stopper member 64 and a second stopper member 65 are attached to the sliding doors 21 and 66 so that the sliding preventing structure of the other handrail is opposed to the sliding door end surface near the summit of the sliding door. In the sliding sliding door 21, the first and second sliding doors 22, 23 are not separated from each other, and in the sliding sliding door 26, the fifth and sixth sliding doors 67, 68 are not separated from each other. The stopper member 64A and the second stopper member 65A are in contact with each other to serve as a restrictor, thereby forming a structure for preventing the other handrail from slipping into the one handrail. And you may use together with the supporting member 11 of the intermediate part of the structure which can translate in an up-down direction. The sliding door handrail 1 and the sliding door handrail 41 may be attached to the shoji screen and the light shoji facing the long corridor according to the embodiment of the present invention. The sliding door handrail 1 or the sliding door handrail Grasping on the handrail 41, elderly people and people with disabilities can walk safely in the long corridor.

(Here, the effect is the same as in FIG. 2 if it is replaced with the third handrail 42 instead of the first handrail 2 in FIG. 2).

  A countersink hole 5A is provided in the center of the first mounting plate 5 from the back surface, and a pair of mounting holes 5B and 5B are provided symmetrically above and below the first mounting plate 5 and the first bush 6A has a hollow cylindrical shape (pipe). The right hand end of the third handrail 42 is inserted, and the set screw 7 is inserted into the right hand end of the third handrail 42 through the screw hole 6C. (See FIG. 8, hole 42C corresponds to hole 2C in FIG. 2). Then, the first mounting plate 5 is brought into contact with the distal end surface portion of the first projecting member 6B, and the stepped screw 6E is screwed into the countersink hole 5A and the screw hole 6D from the back surface. The countersink hole 5A and the stepped portion of the stepped screw 6E are freely rotatable, but the screw hole 6D and the screwed portion of the stepped screw 6E are firmly attached to the sliding door. The right end of the handrail 41 is strongly supported.

  Then, the first support member 4 inserted and attached to the right end of the one third handrail 42 having the hollow cylindrical shape is attached to the pair of mounting holes 5B and 5B, respectively. 8 and 8 are screwed to the right surface of the first sliding door 22. Accordingly, even if the sliding door handrail 41 extending leftward is rotated in the vertical direction, the right end portion of the sliding door handrail 41 is the first support member 4, The first sliding door 22 is supported and securely attached to the right side of the first sliding door 22 although it can be turned. (See Figure 6)

  In other words, the sliding door handrail 41 extending to the left of the first support member 4 is capable of rotating freely corresponding to the movement of the sliding door handrail 41 moving downward or rising upward. In addition, even if a pedestrian grabs or leans on the sliding door handrail 41 and a force is applied, the right end of the sliding door handrail 41 is securely attached and held by the first support member 4. Yes. Therefore, the sliding doors 41 attached to the sliding doors facing the long corridors and passages allow the elderly and handicapped people to walk safely while holding on to the handrails.

  At the time of assembly, the first support member 4 is first attached to the right surface of the first sliding door 22, and then the right end of the third handrail 42 having the hollow cylindrical shape (pipe shape) is attached. The first support member body 6 is inserted into the hole 42 </ b> C at the right end of the one third handrail 42 through the screw hole 6 </ b> C with the set screw 7, and is prevented from coming off. May be attached. To remove the sliding door handrail 1, the set screw 7 may be removed.

  Next, referring to FIG. 7 and FIG. 8, the other end on the left side of the third handrail 42 in the hollow cylindrical shape (pipe shape) near the summit of the first sliding door 22 on the near side is The opening 42A is opened, the inner diameter of the opening 42A is expanded (cutting or mechanical expansion may be used), and a bush or bearing member having a small friction coefficient in the expanded inner diameter of the opening 42A. 42B is installed internally. Accordingly, the other rod-shaped fourth handrail 43 which is inserted and has a telescopic type can be slidably moved in and out of the one third handrail 42. The outside of the opening 42 </ b> A is held horizontally by the fourth support member 51.

  As described above, FIG. 8 is an exploded perspective view of the fourth support member 51 according to the third embodiment of the present invention. The fourth support member 51 is attached to the left surface of the first sliding door 22 at the middle portion of the sliding sliding door 21 near the summon, and the middle portion of the sliding door handrail 41 is horizontally oriented. Hold. The fourth support member 51 includes a fourth support member main body 52 and a fourth mounting plate 53. In the fourth support member main body 52, the fourth bushing 52A and the fourth projecting member 52B are fixed to each other in a substantially inverted T shape, and further on the distal end surface on the other side of the second projecting member 52B. A channel member 52C having a substantially inverted C-shaped cross section is fixed. The material of the fourth support member main body 52 can be made of metal, synthetic resin, or wood.

  Next, the fourth mounting plate 53 has a substantially inverted T-shaped projecting portion 53B having a transverse cross section in the middle of the fourth mounting plate main body 53A, and a rectangular parallelepiped member 53C fixed thereto in contact therewith. Yes. Further, a pair of mounting holes 53D and 53D are provided in the vicinity of the upper and lower ends of the fourth mounting plate main body 53A. The channel member 52C having a substantially inverted C-shaped cross section of the fourth support member body 52 is fitted into the projecting portion 53B having a substantially inverted T-shaped cross section fixed to the fourth mounting plate 53. It is guided to move in the direction. If a downward force is applied to the fourth support member main body 52 and it is lowered, the drop is caused by coming into contact with the rectangular parallelepiped member 53C which is guided by the substantially inverted T-shaped projecting portion 53B and fixed below the cross section. Stop. This means that in the support member 51 that can be translated in the vertical direction, even if a force is applied to the support member 51 when a pedestrian grabs the sliding door handrail 41, the channel member 52C Since it abuts against the rectangular parallelepiped member 53C and is prevented from descending and kept below a certain size, the sliding door rail 41 can be prevented from being deformed. As a result, even if a pedestrian approaches the sliding door rail 41, the sliding door rail 41 can be smoothly expanded and contracted without being deformed, and the sliding sliding door provided with the sliding door rail 41 is provided. Since the opening and closing of the door 21 is smooth, the sliding door 21 can be easily opened and closed for a pedestrian, and it is held by the handrail 41 for the sliding door to assist in walking and is safe.

  Further, in the fourth support member 51, the cross section of the fourth support member main body 52 is substantially reversed C to the projecting portion 53 </ b> B having a substantially transverse cross section fixed to the fourth mounting plate 53. Since the channel-shaped channel member 52C can be inserted and guided in parallel translation in the vertical direction, the center portion of the sill is lowered downward (or due to distortion, deformation, wear, etc. of an aging ordinary house) (or On the other hand, even if the sliding door or the sliding sliding door is inclined), for example, specifically in the sliding sliding door 21, the first sliding door 22 and the second sliding door 21 are tilted upward). Even if the sliding door 23 is tilted so as to fall into the Katakana half-shaped shape (or even if the sliding door 23 is tilted so as to fall into the reverse half-shaped Katakana shape), the sliding door handrail 41 of the sliding door 21 is reversed. Summon The fourth support member body 52 of the fourth support member 51 near the portion (the central portion where the edges of the sliding sliding door 21 in the closed state meet and overlap each other) is slidably guided downward (or the first 4 support member main body 52 is slid and guided upward), and the distance from the center of the handrail member axis of the sliding door handrail 1 near the summing portion of the sliding sliding door 21 to the upper surface of the first rail or first silt groove 34A Alternatively, the distance to the upper surface of the second rail or the second sill groove 34B is H + h (h is a positive value in the lowering amount of the central portion when the sill 34 is recessed downward, and conversely h is the sill 34 Even if it is a negative value in the upward amount when it is convex upward (see FIG. 11), it is also when the sill 34 bends downward in a concave state (so-called slack state) (or conversely upwards). The fourth support member main body 52 also in the case of bending in a convex state). The channel member 52C having a substantially inverted C-shaped cross section is inserted and guided in parallel translation in the vertical direction, and automatically translated in accordance with the upward (or downward) amount of change, and the handrail of the sliding door handrail 1 is corrected. The center of the member axis is not stretched so as to be forcibly arranged on the same line and is naturally held on the same line, and the bending deformation force of the sliding door handrail 41 attached to and supported by the sliding sliding door 21 is reduced. The sliding sliding door 21 can be smoothly opened and closed because the sliding sliding door 21 can slide freely.

  The rectangular parallelepiped member 53C serves as a limiter (stopper) for the downward movement of the fourth support member main body 52. In other words, even if a pedestrian grabs and leans on the sliding door handrail 41, the sliding door handrail 1 is prevented from further descending by the fourth support member 51, and a restrictor (stopper) Since it plays a role, it is possible to prevent the sliding door rail 1 from being deformed too much and to ensure the safety of pedestrians.

  Further, the fourth bushing 52A of the fourth support member main body 52 is provided with a screw hole 52D. Then, the left other end of the one third handrail 42 having a hollow cylindrical shape (pipe shape) is inserted into the fourth bush 52A. The inner diameter of the opening 42A at the other end on the left side of the one third handrail 42 in the hollow cylindrical shape (pipe shape) is expanded (may be cut or mechanically expanded), and the expanded inner diameter A bush (bearing member) 42B having a small friction coefficient is provided in the part. The bush (bearing member) 42B may be a sliding bearing made of synthetic resin such as nylon, polyimide, polyethylene, or tetrafluoroethylene resin, or may be a sliding bearing using graphite or molybdenum disulfide, or other rolling elements. A bearing may be used. This is the same as the bush (bearing member) 2B. (See Figs. 2 and 3)

  The inside of the bush (bearing member) 42B provided in the opening 42A at the other end on the left side of the one third handrail 42 in the hollow cylindrical shape (pipe shape) The fourth handrail 43 is smoothly slid and guided. Thus, the sliding door handrail 41 is attached, and the sliding sliding door 21 that moves in parallel with the sliding door handrail 41 can be opened and closed smoothly. Further, a hole 42 </ b> D is provided in the vicinity of the opening 42 </ b> A at the other end on the left side of the one third handrail 42 having the hollow cylindrical shape (pipe shape). The hole 42D is preferably located away from the place where the bush (bearing member) 42B is provided. However, when the bush (bearing member) 42B is a synthetic resin slide bearing or the like, it will be described later. The set screw 55 to be inserted into the slide bearing 42B may be used, the position where the bush (bearing member) 42B is provided is avoided, and the bush (bearing member) 42B serves to prevent the bushing (bearing member) 42B from coming off. You may provide the hole 42D in the position which can fulfill.

  The fourth support member 51 is attached to the left surface of the first sliding door 22 using set screws 54 and 54 in a pair of upper and lower attachment holes 53D and 53D of the fourth attachment plate 53. Mounted. As described above, the other end on the left side of the one third handrail 42 having a hollow cylindrical shape (pipe shape) is inserted into the fourth bush 52A, and this hollow cylindrical shape (pipe shape) is further inserted. ) In the bush (bearing member) 42B in the enlarged inner diameter portion of the opening 42A at the other end on the left side of the one third handrail 42, and further on the right side of the rod-like fourth handrail 43. An intermediate portion of the sliding door handrail 41 which is inserted into an end portion and is telescopically held is horizontally and smoothly slidable by the fourth support member 51.

  In the sliding door balustrade 41 in which the rod-like 4th balustrade 43 is fitted into the one hollow third balustrade (pipes) 42 and the telescopic door balustrade 41 is formed in a hollow form (pipes). As described above, the hole 42 </ b> D is provided in the vicinity of the opening 42 </ b> A at the other left end of the one third handrail 42. The rod-like fourth handrail 43 is engraved with a groove 43A from the vicinity of the other end on the left side to the vicinity of the one end on the right side, almost the entire length except for the left and right ends. The right end of the groove 43A forms a groove end stopper 43B (see FIG. 8). Then, the other end on the left side of the one third handrail 42 is inserted into the fourth bush 52A, and further, the left side of the one third handrail 42 in the hollow cylindrical shape (pipe shape). The right end of the rod-shaped fourth handrail 43 is fitted and supported via the bush (bearing member) 2B of the opening 42A at the other end, and the set screw 55 is screwed into the screw hole 52D. Then, the front end of the set screw 55 is inserted into the hole 42D and the groove 43B so as to face (in the direction of arrow X in FIG. 8). Accordingly, the set screw 55 and the groove 43 </ b> A form a nesting-type prevention structure for the other fourth handrail 43 fitted into the one third handrail 42. Here, the groove 43A provided in the other fourth handrail 43 may be a cut groove when the other fourth handrail 43 has a round bar shape, or may be a pressing groove or a cut groove in the case of a pipe material. But you can.

  The set screw 55 is fitted into the screw hole 52C of the fourth bush 52A, the hole 42D provided in the vicinity of the other end on the left side of the third handrail 42, and the groove 43A provided in the fourth handrail 43, so that the hollow cylinder The other bar-shaped fourth handrail 43 is prevented from coming out of the third handrail 42 having a pipe shape. This eliminates the need for troublesome assembly work when the mating state comes off, and the elderly or the handicapped people get caught or lean on the long corridor facing the shoji or light shoji. Since the structure for preventing the other fourth handrail 43 from slipping into the third handrail 42 is formed, the one third handrail 42 does not come out of the fourth handrail 43 and the sliding door handrail. It is possible to walk safely in a long corridor while holding onto 41. Of course, the sliding door rail 41 can be attached not only to the corridor side but also to the sliding door 21 on the indoor side, so that it is possible to walk safely in the room.

  Then, the other end on the left side of the other fourth handrail 43 in the form of a rod is placed in the third bush 18A of the third support member 17 on the left surface of the second sliding door 23 on the back side. The left other end portion of the fourth handrail 43 is inserted and screwed into the screw hole 18C and the stop hole 43C using the mounting screw 20A, so that the left hand side of the other fourth handrail 43 and the like. The end is held horizontally by the third support member 17. The configuration and operational effects of the third support member 17 are the same as those described with reference to FIG. (In FIG. 6, the other fourth handrail 43 is replaced in place of the other second handrail 3 in FIG. 4.)

  That is, the sliding door handrail 41 attached to the sliding sliding door 21 is held in the horizontal direction by the third support member 17 at the other end on the left side, and the first sliding door 22 and the first sliding door 21. Even when two sliding doors 23 are separated from each other for reasons such as aging of the building or when the sliding sliding doors 21 have different thicknesses, the third protruding member 18B and the protruding members By allowing the bar member 19B to be translated in parallel, the other end on the left side of the other fourth handrail 43 can be translated in the thickness direction of the sliding door, and the dimensional difference can be absorbed. The handrail member shaft center of the one third handrail 42 attached to the first sliding door 22 on the side and the handrail of the rod-like fourth handrail 43 attached to the second sliding door 23 on the back side Nested so that it is on the same line as the member axis center The sliding door handrail 41 can slide smoothly and freely, so that the first sliding door 22 and the second sliding door 23 constituting the sliding sliding door 21 to which the sliding door handrail 41 is attached are provided. It can be opened and closed smoothly.

  That is, the third support member 17 can cope with various sliding door thicknesses that did not have a unified standard, and the sliding door handrail 41 can be easily applied to various types of sliding doors and sliding sliding doors. is there. Therefore, the sliding door handrail 41 of the present invention is held in the horizontal direction by the third support member 17, and the other left end portion of the sliding door handrail 41 can be translated in the sliding door thickness direction. Adjustment is not required, cost is low, installation is easy, and it is convenient to apply to various types of sliding doors and sliding sliding doors.

  In the third embodiment of the present invention, the sliding door 41 is easily attached to and removed from the sliding door 21 by attaching and detaching the set screw 7 and set screw 8 in the first support member 4. Yes. The fourth support member 51 can also be easily performed by attaching and detaching the set screw 54 and the set screw 55. And in the 3rd supporting member 17, it can carry out easily by attachment or detachment of mounting screw 20A, 2OB, 20C.

  Then, due to distortion or deflection of the sill 34 due to reasons such as an aging house, the second sliding door 23 on the back side is displaced upward relative to the first sliding door 22 on the near side, or conversely Even in the shifted state, the one third handrail 42 is rotatably supported around the first support member 4, and the intermediate portion is attached and supported by the fourth support member 51, so that the bush ( Since the frictional force is reduced by the bearing member 42 </ b> B, the telescoping handrail 41 for sliding doors can slide smoothly and freely, and as a result, the sliding sliding door 21 can be opened and closed smoothly.

  As described above (see FIGS. 7 and 8), the fourth support member 51 has the same basic function as the second support member 11, but is nested in the third handrail 42. A difference is that a structure (stopper structure) for preventing the detachment of the nesting part by the groove end stopper 43A and the set screw 54 is provided so that the right end of the fourth handrail 43 is not removed. When the channel member 52C having a substantially inverted C-shaped cross section inserted in the substantially inverted T-shaped projecting portion 13B is guided in the vertical direction and a person grabs on the sliding door handrail 41, the fourth Even if a force is applied to the supporting member 51, the sliding door handrail 41 is deformed by the channel member 52C having a substantially reverse C-shaped cross section abutting against the rectangular parallelepiped member 13C and being prevented from descending. It can be prevented and can play the role of a restrictor (stopper), so that it is possible to prevent the sliding door handrail 41 from being deformed too much and to ensure the safety of pedestrians.

  As described above, the right half of the opening 33 (not shown) between the pillars 32A and 32B is configured symmetrically with the left half, and the first sliding door 22 is changed to the third sliding door 42, and the second sliding door 42 is changed to the second sliding door 42. The sliding door 23 is replaced with the fourth sliding door 43, and the direction of the sliding door handrail 41 that is nested by inserting the rod-like fourth handrail 43 into the hollow tubular (pipe-shaped) third handrail 42 is 180. Considering the opposite direction, the left half has the same configuration as the right half, and the operational effects are the same, so the description of the right half is omitted.

  Therefore, as explained in accordance with FIGS. 6, 7, and 8, the pair of sliding sliding doors 21 and 61 facing the long corridor and symmetrically disposed opposite to each other have a hollow cylindrical shape (pipe The sliding handrails 41 and 41, which are nested, are inserted into the third handrail 42 in the form of a rod and the telescoping handrails 41 and 41 are attached to face each other. In the middle portion near the summoning, the fourth support member 51 is attached and held in the horizontal direction. In the fourth support member 51, from the one third handrail 42 having a hollow cylindrical shape (pipe shape), Since the stopper structure by the groove end stopper 43A and the set screw 54 is provided so that the right end of the other rod-shaped fourth handrail 43 inserted does not come off, the sliding door 22 is located on the right side of the sill 34. If you go too far, the nesting part will not come off (see above In the case of the sliding door 61, the telescoping part does not come off even if the third sliding door 62 goes too far to the left), so that it is not necessary to perform troublesome assembling work as in the case where the fitting state of the telescoping part is removed. The third handrail 42 does not come out of the fourth handrail 43 and the third handrail 42 does not come out even if elderly people or people with disabilities in the limbs grab or lean on the long corridor facing the shoji and light shoji. You can walk safely in a long corridor while holding. (See Figure 6)

  Furthermore, even if a pedestrian grabs and leans on the sliding door handrail 41 provided in the long corridor, the rotating action of the first support member 4 or the fourth support member 51 further increases the sliding door handrail. 41 prevents the lowering 41 from descending, and serves as a structure for preventing the detachment of the telescoping part (stopper structure), so that the sliding sliding doors 41, 41 can be prevented from being deformed too much, and the sliding sliding doors 21, 61 are smooth. The door can be opened and closed and the safety of the pedestrian can be ensured. The first sliding door 2 of the sliding sliding door 21 and the second sliding door even when forces are applied in directions away from each other due to aging of the building itself by the third support member 17. The fourth pipe member 18B and the bar member 19B may be different even if the thickness of the sliding door 3 is different, or the thickness of the fifth sliding door 62 of the sliding sliding door 61 or the sliding door of the sixth sliding door 63 is different. Since the sliding door handrail 41 can slide smoothly and retractably, the sliding door door with the sliding door handrails 41 and 41 attached thereto can be relatively translated. 21 and 61 can be opened and closed smoothly. Furthermore, it is only necessary to prepare one type of the support member 17 that can be moved in the thickness direction of the sliding door, and the handling is easy, and an inexpensive handrail for sliding doors can be supplied.

  Next, FIG. 9 is a perspective view of the fourth embodiment of the present invention. As shown in FIG. 9, the sliding sliding door 21 including the left first sliding door 22 and the second sliding door 23 facing the opening 33 (not shown) between the pillars 32 </ b> A and 32 </ b> B, and the right side A sliding sliding door 66 composed of a fifth sliding door 67 and a sixth sliding door 68 is disposed in a pair, and the sliding sliding door 21 and the sliding sliding door 66 are arranged in a hollow cylindrical shape. The second handrail 3 in the form of a rod is inserted into the first handrail 2 and the sliding-type handrail 1 nesting is opposed to each other in the horizontal direction symmetrically, and the sliding sliding door 21 and the sliding sliding door 66 are attached. And a support member 11 that supports the sliding door handrail 1 in the middle portion of each of the summits and can be moved in parallel in the vertical direction, and the other second fitting member that fits into the first handrail 2.

The member 64 is mounted with a set screw 70 so that the protruding portion 64A protrudes toward the second sliding door 23 so as not to contact, and protrudes to the lower right end of the second sliding door 23. A second stopper member 65 having a portion 65A and a mounting hole 65B is attached to the set screw 70 by projecting the projecting portion 65A toward the first sliding door 22 so as not to contact. Next, at the lower right end portion of the fifth sliding door 67 of the sliding sliding door 66 shown in the Z portion (enlarged view) of FIG. The first stopper member 64 provided with 64A is protruded to the sixth sliding door 68 side so as not to contact, and is attached by a set screw 70, and a protruding portion 65A and a mounting hole 65B are attached to the lower left end portion of the sixth sliding door 68. The second stopper member 65 having the above-described structure is mounted at the set screw 70 by projecting the projecting portion 65 </ b> A toward the fifth sliding door 67 side so as not to come into contact therewith. Accordingly, in the sliding sliding door 21, when the first sliding door 22 is moved to the right, the first stopper member 64 and the second stopper member 65 come into contact with each other with the protruding portion 64A and the protruding portion 65A. Thus, the second sliding door 23 is connected and moved to prevent the nesting portion of the other second handrail 3 to be fitted into the one first handrail 2 of the attached handrail 1 for the sliding door. Forming a structure. Similarly, in the sliding sliding door 66, when the fifth sliding door 67 is moved to the left, the first stopper member 64 and the second stopper member 65 are brought into contact with each other with the protruding portion 64A and the protruding portion 65A. In contact therewith, the sixth sliding door 68 is connected and moved, and the nesting portion of the other second handrail 3 fitted into the one first handrail 2 of the attached sliding door handrail 1 is removed. A prevention structure is formed.

  In the sliding sliding door 21 and the sliding sliding door 66, the rod-shaped second handrail 3 is fitted into the one first handrail 2 having a hollow cylindrical shape (pipe shape) so that the telescopic sliding door 21 and the sliding sliding door 66 are nested. The sliding handrails 1 to be formed are provided in the horizontal direction so as to face each other. First, the sliding sliding door 21 will be described. In the left half of the opening 33 (not shown), on the right surface of the first sliding door 22 that forms the sliding sliding door 21, the right side of the first handrail 2 in the shape of a hollow cylinder (pipe) One end of one side is horizontally supported by the first support member 4, and the other end on the left side of the first handrail 2 in the shape of a hollow cylinder (pipe-shaped) near the summit is horizontally supported by the second support member 11. The other left hand end of the second bar-shaped handrail 3 is held horizontally by the third support member 17 on the left surface of the second sliding door 23, and the other second bar-shaped second handrail 3 is held. The right end of the handrail 3 has a hollow cylindrical shape (pipe shape) near the summit, and the bush ( Bearing member) 2B is fitted and telescopically held horizontally in a telescopic manner. In this way, the intermediate portion of the sliding door handrail 1 can translate the sliding door handrail 1 in the vertical direction by the support member 11, and both end portions of the sliding door handrail 1 are located on the left side. The first stopper member 64, the second stopper member 65, and the second stopper member 65 are held horizontally by the third support member 17 so as to be rotatable by the support member 4. Is provided on the sliding door side to constitute a structure for preventing the telescopic part of the sliding door rail 1 from coming off.

  Next, the sliding sliding door 66 will be described (see FIG. 9). On the left half surface of the fifth sliding door 67 forming the sliding sliding door 66 in the right half of the opening 33 (not shown), the left one end of the first handrail 2 in the shape of a hollow cylinder (pipe). However, due to the first support member 4, the right other end of the first handrail 2 in the shape of a hollow cylinder (pipe-shaped) near the summit is placed on the right surface of the fifth sliding door 67. 2 is held horizontally by the second support member 11, and the other right hand end of the other rod-like second handrail 3 is held horizontally by the third support member 17, and the other rod-like second handrail 3 is held. One end on the left side of the first is fitted into an opening 2A (not shown) on the other end on the right side of the first handrail 2 in the shape of a hollow cylinder (pipe) near the summons, and telescopically expands and contracts. It is freely held horizontally. In this way, the middle portion of the sliding door handrail 1 can move the sliding door handrail 41 in the vertical direction, and the first stopper member 64 and the second stopper member 65 are provided on the sliding door side, and the sliding door handrail is provided. The structure for preventing the detachment of the telescopic part 1 is configured.

  As for the operation and effect of the sliding door handrail 1 according to the fourth embodiment of the present invention, the first rail on the sill 34 or the first sill groove 34A, the second rail, as described above with reference to FIG. Alternatively, the sliding sliding door 21 and the sliding sliding door 66 guided in the second sill groove 34B may correspond to the unevenness of the sill 34 for reasons such as aging of the building itself. The linearity of the sliding door handrail 1 is ensured by the action and effect of the support members 4 and 11 and by the action and effect of the third support member 17 in the difference in the sliding door thickness of the sliding sliding doors 21 and 66. Since the sliding of the sliding door 1 can be smoothly and freely slidable because the displacement of the position can be absorbed, the sliding sliding doors 21 and 66 to which the sliding door 1 is attached can be opened and closed smoothly. ,

  Furthermore, even if a pedestrian grabs and leans on the sliding door handrail 41 provided in the long corridor, the rotating action of the first support member 4 or the second support member 11 further increases the sliding door handrail. 41, and when the third support member 17 exerts a force in a direction away from each other for reasons such as aging of the building itself, Even if the sliding door thickness of the first sliding door 2 or the second sliding door 3 is different, or the thickness of the fifth sliding door 62 of the sliding sliding door 61 or the sliding door of the sixth sliding door 63 is different. The fourth pipe member 18B and the bar member 19B can be moved in parallel with each other, and the positional deviation can be absorbed.

The rod-like fourth handrail 43 is prevented from coming off from the one third handrail 42. This eliminates the need for troublesome assembly work when the mating state comes off, and the elderly or the handicapped people get caught or lean on the long corridor facing the shoji or light shoji. Since the structure for preventing the other fourth handrail 43 from slipping into the third handrail 42 is formed, the one third handrail 42 does not come out of the fourth handrail 43 and the sliding door handrail. It is possible to walk safely in a long corridor while holding onto 41.
