It is a top view which shows the assembly 3rd process of a handrail. It is a top view which shows the assembly 4th process of a handrail.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a schematic diagram showing an example of an elevator apparatus according to the present invention. As shown in FIG. 1, an elevator apparatus 20 according to the present invention includes a car 22 that moves up and down a hoistway 21, a counterweight 23 that moves up and down together with the car 22, one end connected to the car 22, and the other end Has a main rope 24 connected to a counterweight 23 and a hoisting machine 25 having a sheave around which the main rope 24 is wound. A handrail (not shown) is attached inside the car 22.

  Next, the structure of the handrail will be described in detail. FIG. 2 is a plan view of the car of FIG. As shown in FIG. 2, the car 22 has front side plates 2A and 2B, side side plates 3A and 3B, and a rear side plate 4 as side walls. More specifically, a pair of front side plates 2A, 2B adjacent to both sides of the entrance / exit 1 of the car 22, the side plates 3A, 3B connected to the front side plates 2A, 2B, respectively, on the side opposite to the entrance / exit 1 Both ends have a rear side plate 4 connected to the side plates 3A and 3B. A series of handrails fixed at predetermined height positions using a plurality of support brackets 5 are attached to the inner surfaces of the lateral side plates 3A and 3B and the rear side plate 4 of the car. The handrail is made of, for example, an aluminum pipe, and can be used as an aid for moving a wheelchair user or the like in the car. In this embodiment, the handrail is divided into three parts, a rear handrail 6 fixed to the rear side plate 4 and side handrails 7A and 7B fixed to the side plates 3A and 3B, respectively, at the same height position. It is arranged horizontally. Such a handrail provided in the elevator car serves as a support when the passenger leans on the body and leans on the side plate.

  As shown in FIG. 2, the rear handrail 6 has a main portion substantially linear along the rear side plate 4, and both ends thereof are bent from the rear side plate 4 along the side plates 3 </ b> A and 3 </ b> B. A curved surface portion having a shape is included. At the tip of the bent curved surface portion, there is an end portion having a substantially linear shape along the lateral side plates 3A and 3B. The side handrails 7A and 7B are connected to the end of the rear handrail 6 and have a substantially linear shape along the lateral side plates 3A and 3B. The connecting portion of the rear handrail 6 and the side handrail 7A has the same configuration as the connecting portion 8 of the rear handrail 6 and the side handrail 7B.

  Since the handrail is thus divided into three parts, each component of the handrail (the rear handrail 6 and the side handrails 7A and 7B) can be easily carried into the car 22 from the doorway 1 separately. it can. Moreover, even if the handrails are arranged in three directions in the car, the divided portions of the handrail are formed not on the corners of the handrail but on the portions having the linear shape of the constituent members. For this reason, it is possible to reduce the number of connecting portions of the handrail constituent members as compared with the conventional case where the corner body is provided with a corner body, and to make the handrail excellent in usability, designability and manufacturability. Can do.

  Next, the assembly process of the handrail mentioned above is demonstrated. FIG. 3 is a plan view showing a first step of assembling the handrail, and FIG. 4 is a plan view showing a second step of assembling the handrail. When attaching the handrail to the inside of the car, the operator first arranges the rear handrail 6 substantially horizontally along the inner surface of the rear side plate 4 as shown in FIG. Fix to 4.

  As described above, since the curved surface portion and the end portion are integrally formed on the rear handrail 6 in advance, both ends of the rear handrail 6 are disposed on the side plate 3A in a state where the attachment of the rear handrail 6 is completed. , 3B and extending substantially horizontally.

  Next, as shown in FIG. 4, the operator arranges the side handrail 7B substantially horizontally along the inner surface of the side plate 3B, and uses the support bracket 5 in the same manner as the case of the rear handrail 6 to use the side plate 3B. Secure to. Note that either of the side handrails 7A and 7B may be fixed first, but the case where the side handrail 7B is assembled first will be described below. At this time, as in the case where the rear handrail 6 is fixed to the rear side plate 4, the side handrail 7B may be fixed to the lateral side plate 3B using a plurality of support brackets 5, as shown in FIG. The other end of the side handrail 7B (the end opposite to the end connected to the rear handrail 6) is directly fixed to the lateral plate 3B. The side handrail 7B may be fixed to the lateral side plate 3B by the support bracket 9. As shown in FIG. 4, the side handrail 7B is arranged so that the end of the rear handrail 6 that has been attached and the end of the side handrail 7B come into contact with each other, and the support bracket 5 and other brackets 9 The state is fixed or temporarily fixed to the side plate 3B.

  Thereafter, the end of the rear handrail 6 and the end of the side handrail 7B arranged in contact with the end of the rear handrail 6 are referred to as a moving joint (hereinafter simply referred to as “joint”). Connect with

  Hereinafter, the joint will be described in detail. FIG. 5 is a top view showing an end portion of the side handrail before being connected to the rear handrail. The connection of the rear handrail 6 and the side handrail 7B is housed in the side handrail 7B after the side handrail 7B is installed, and is movable in the axial direction (longitudinal direction) of the side handrail 7B. This is done by the joint 10.

  The side handrail 7B is made of, for example, a hollow aluminum pipe, and as shown in FIG. 5, a joint 10 having a cylindrical shape is inserted (accommodated) at the end on the connecting portion 8 side. As shown in FIG. 6, the joint 10 is formed with a plurality of screw holes 11 extending from the surface toward the center, and the side handrail 7B has a plurality of screw holes 11 as shown in FIG. A slit 12 having a predetermined length in the axial direction is formed at a position opposite to. A low head screw (hereinafter simply referred to as “screw”) 13 is inserted into a screw hole 11b located on the connecting portion 8 side among the plurality of screw holes (11a and 11b in FIG. 5). Since the joint 10 and the side handrail 7B are fixed via the screw 13 in the storage state of the joint 10, the joint 10 moves so as to protrude from the end of the side handrail 7B. Absent. In this way, the side handrail 7B in which the joint 10 is stored in advance is prepared, and this is carried into the car, and the handrail is assembled in the car. As the screw 13, it is preferable to use a low-head screw with a small protruding screw head. By using the low head screw, it is possible to reduce a sense of incongruity when the user grips the handrail after the handrail is assembled. In addition, even during storage before assembling the handrail, it is possible to prevent the surrounding strings from being caught and hindering the assembly work.

  FIG. 7 is a top view showing a third step of handrail assembly, and FIG. 8 is a top view showing a fourth step of handrail assembly. 7 and 8 are enlarged views of the connecting portion 8 between the rear handrail 6 and the side handrail 7B shown in FIG.

  In the side handrail 7B in which the joint 10 shown in FIG. 5 is accommodated, when the screw 13 (first screw) is once removed from the screw hole 11b and inserted into the screw hole 11a, the screw 13 extends along the slit 12. And it can be moved by the axial length of the slit 12 (FIG. 7). Therefore, when the operator picks the screw 13 inserted into the screw hole 11a and moves it in the axial direction (the direction of arrow A in FIG. 7), this time, the joint 10 is moved to the side hand. A predetermined distance can be projected from the end of the rail 7B. The protruding distance of the joint 10 at this time can be appropriately adjusted according to the position and length of the slit 12, the length of the joint 10, and the like.

  A fixing hole 15 for fixing the screw 13 (first screw) is formed on the surface of the end of the rear handrail 6 in advance. The fixing hole 15 is sized so that the screw 13 can be inserted, and is positioned in relation to the screw holes 11 provided at both ends of the slit 12 formed in the side handrail 7B. That is, in the state where the rear handrail 6 and the side handrail 7B are connected, the distance between the screw holes 11a and 11b formed at both ends of the slit 12 and the screw formed on the rear handrail 6 side in the slit 12 The distance between the hole 11b and the fixing hole 15 is equal. Of course, in order to absorb a dimensional error, the fixing hole 15 may be a long hole elongated in the axial direction.

  An operator picks the screw 13 and moves the screw 13 to the connecting portion side by the length of the slit 12. Then, together with the screw 13, the joint 10 coupled to the screw 13 moves in the same manner, and the tip (insertion side end) of the joint 10 is inserted into the rear handrail 6. This insertion length corresponds to the length of the slit 12. The screw hole 11b in which the screw 13 is inserted when the joint 10 is stored moves along the straight shape of the rear handrail 6 and the side handrail 7B (in the direction of arrow B in FIG. 7) and is formed on the rear handrail 6 side. It moves to a position facing the fixed fixing hole 15. In this state, the operator inserts another screw 16 (second screw) into the fixing hole 15 (FIG. 8), and fixes the screw 13 (first screw) to the screw hole 11b. Then, as shown in FIG. 8, the joint 10 is fixed to the side handrail 7B and the rear handrail 6 at two locations of the screw 13 and the screw 16, and the rear handrail 6 and the side handrail 7B are substantially Concatenated continuously. That is, the connecting surface 17 between the rear handrail 6 and the side handrail 7B is fixed through the joint 10. The other end of the rear handrail 6 and the side handrail 7A are similarly connected.

  Next, the case where the joint 10 is housed inside the side handrail 7B will be described, contrary to the case described above. In the state of FIG. 8, the screw 16 (second screw) is first removed, and the screw 13 (first screw) is loosened. Then, the operator can pinch the screw 13 and move the joint 10 along the slit 12. When the screw 13 is moved to the screw hole 11a provided in the side handrail 7B, the joint 10 is completely stored in the side handrail 7B. In this state, by fixing the screw 13 in the screw hole 11a, the joint 10 is fixed in a state of being accommodated in the side handrail 7B.

  In the embodiment described above, the slit 12 is provided so as to be positioned directly above the side handrail 7B when the side handrail 7B is viewed from the surface connected to the rear handrail. It may be formed at any position on the surface of the handrail 7B. It is preferable to determine the position of the slit 12 in consideration of the workability of the joint movement described above. The same applies to the fixing hole 15 of the rear handrail 6.

  As shown in FIG. 5, in the side handrail 7B, one end of the support bracket 5 is connected to a position where the movement of the joint 10 is not hindered, and a bolt 14 provided on the other end of the support bracket 5 is connected. The side handrail 7B can be fixed to the lateral side plate 3B by using it. If the car 22 is assembled after fixing at least the bolt 14 side of the support bracket 5 to the side plate 3B in advance, the side handrail 7B idles only from the inside of the car to the main body side of the support bracket 5 and is inserted into the bolt 14. It can be fixed by doing.

As described above, since the handrail installed in the elevator apparatus according to the present invention is divided into three parts, each component of the handrail can be easily carried in from the doorway 1 in a state before connection. Moreover, even if the handrails are arranged in three directions in the car, it is considered that each divided portion of the handrail is positioned not in the corner portion of the handrail but in a substantially straight portion. For this reason, the joint 10 which moves the end part which has the linear shape of the rear handrail 6 and the end part which has the linear shape of the side handrails 7A and 7B to face each other and moves in the coaxial direction is used. Thus, the working efficiency can be improved without increasing the number of connecting points. Moreover, it can be set as the handrail which hold | maintained the designability as a whole, maintaining the designability of a connection part.

  In this way, since the entire handrail is connected as if it were a continuous and integral structure, the outer surface can be formed more smoothly. Therefore, when a wheelchair user or the like moves inside the car while being caught by the handrail, the user can move smoothly without being restricted in the car using the uninterrupted handrail. Can be achieved, and the user is not injured or discomforted.

  As described above, according to the present invention, the in-car handrail is provided which has few connection points, is excellent in feeling of use, designability and manufacturability, and can be easily assembled only by in-car work. It has been shown that an elevator device can be provided.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.

  Specifically, in the above-described embodiment, the handrail is divided into three members, that is, the rear handrail 6 and the side handrails 7A and 7B. However, the number and specific shapes of the constituent members are limited. Not what you want. For example, the curved portions may be integrally formed in advance on the side handrails 7A and 7B, and the rear handrail 6 may be formed in a substantially straight line shape.

  In the above-described embodiment, the joint 10 is housed inside the side handrail 7B. However, a tubular joint 10 that is movable in the axial direction may be provided outside the side handrail 7B. The joint 10 may be provided inside the rear handrail 6 instead of the side handrails 7A and 7B.

  Furthermore, if the rear handrail 6 and the side handrails 7A and 7B can be attached to the support bracket 5 so that the positions thereof can be adjusted, the rear handrail 6 and the side handrails 7A and 7B should be arranged very close to each other. Since the moving joint 10 can be moved smoothly, it is possible to further improve the feeling of use, the designability and the manufacturability of the connecting portion 8.
