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.

  Hereinafter, embodiments of the present invention will be described based on the drawings.

  FIG. 1 is a schematic view 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 moving up and down a hoistway 21, a counterweight 23 moving 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 on which the main rope 24 is wound. A handrail (not shown) is attached to the inside of 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 plates 3A and 3B, and a rear side plate 4 as side walls. More specifically, a pair of front side plates 2A and 2B adjacent to both sides of the entrance 1 of the car 22 and lateral side plates 3A and 3B to which the front side plates 2A and 2B are respectively connected It has a rear side plate 4 whose both ends are connected to the side plates 3A and 3B. On the inner surfaces of the side plates 3A, 3B and the rear side plate 4 of the car, a series of handrails fixed at a predetermined height position using a plurality of support brackets 5 are attached. The handrail is made of, for example, an aluminum pipe, and can be used to assist the movement of a wheelchair user or the like in the car. In this embodiment, the handrail is divided into three parts, the rear handrail 6 fixed to the rear side plate 4 and the side handrails 7A and 7B fixed to the side plates 3A and 3B, respectively, at the same height position. It is arranged horizontally. Such handrails, which are provided in the elevator system's car, provide support when the passengers leave their body and lean on the side plates.

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

  Thus, since the handrail is divided into three, each component (rear handrail 6 and side handrails 7A, 7B) of the handrail can be easily carried into the car 22 from the entrance 1 separately. it can. Moreover, even if the handrails are arranged in three directions in the car, each divided portion of the handrail is formed not in the corner of the handrail but in the portion having the linear shape of the component. For this reason, it is possible to reduce the number of connection places of the handrail constituent members compared to the case where corner bodies are provided at the corners as in the prior art and to provide a handrail excellent in feeling in use, designability and manufacturability. Can.

  Next, the assembly process of the handrail mentioned above is demonstrated. FIG. 3 is a plan view showing a first assembly step of the handrail, and FIG. 4 is a plan view showing a second assembly step of 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 it to 4.

  As described above, since the curved portion and the end are formed in advance integrally with the rear handrail 6, both ends of the rear handrail 6 are the side plates 3A in a state where the installation of the rear handrail 6 is completed. , 3B, and extends substantially horizontally.

  Then, the operator arranges the side handrail 7B substantially horizontally along the inner surface of the side plate 3B as shown in FIG. 4 and uses the support bracket 5 as in the case of the rear handrail 6 so as to form the side plate 3B. Fix to Although either of the side handrails 7A and 7B may be fixed first, 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. , And the other structure having a similar configuration to the support bracket 5 so that the end of the side handrail 7B (the end opposite to the end connected to the rear handrail 6) is directly fixed to the side plate 3B. The side handrail 7B may be fixed to the side plate 3B by the support bracket 9. As shown in FIG. 4, the side handrail 7B is disposed so that the end of the rear handrail 6 which has been completely attached and the end of the side handrail 7B come into contact with each other. It 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 disposed in contact with the end of the rear handrail 6 are a moving joint (hereinafter simply referred to as "joint"). Concatenate by

  Hereinafter, this joint will be described in detail. FIG. 5 is a top view showing the end of the side handrail prior to connection to the rear handrail. The connection of the rear handrail 6 and the side handrail 7B is housed inside the side handrail 7B after the installation of the side handrail 7B, and can be moved in the axial direction (longitudinal direction) of the side handrail 7B. It is performed by the joint 10.

  The side handrail 7B is made of, for example, a hollow aluminum pipe, and as shown in FIG. 5, the joint 10 having a cylindrical shape is inserted (stored) at the end on the connection portion 8 side. As shown in FIG. 6, a plurality of screw holes 11 extending from the surface toward the center are formed in the joint 10. As shown in FIG. The slit 12 which has predetermined length in the axial direction is formed in the position which opposes. A low head screw (hereinafter simply referred to as a "screw") 13 is inserted into the screw hole 11b located on the connection portion 8 side among the plurality of screw holes (in FIG. 5, 11a and 11b). 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. Thus, the side handrail 7B in which the joint 10 is stored in advance is prepared and carried into the car, and the handrail is assembled in the car. The screw 13 is preferably a low-head screw with a small protrusion of the screw head. By using a low head screw, after assembly of the handrail, it is possible to reduce the discomfort when the user grips the handrail. Further, even when stored before assembling the handrail, it is possible to prevent the cords and the like in the surrounding area from being caught and disturbing the assembling operation.

  FIG. 7 is a top view showing a third assembly process of the handrail, and FIG. 8 is a top view showing a fourth assembly process of the handrail. 7 and 8 are enlarged views of the connecting portion 8 of 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 stored, the screw 13 (first screw) is once removed from the screw hole 11b and inserted into the screw hole 11a. And, it can be moved by an axial length of the slit 12 (FIG. 7). Therefore, when the operator picks up the screw 13 inserted in the screw hole 11a and moves it in the axial direction (direction of arrow A in FIG. 7), this time, unlike the state when stored earlier, the joint 10 is used as a side hand It can be made to project from the end of the rail 7B by a predetermined distance. The projection distance of the joint 10 at this time can be appropriately adjusted depending on the position, length, and length of the joint 10 of the slit 12 and the like.

  At the end of the rear handrail 6, a fixing hole 15 for fixing the screw 13 (first screw) on the surface thereof is formed in advance. The fixing holes 15 are positioned so that the screws 13 can be inserted, and 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 11 b and the fixing hole 15 is made equal. Of course, the fixing holes 15 may be elongated in the axial direction in order to absorb dimensional errors.

  The operator picks the screw 13 and moves the screw 13 toward the connecting portion by the length of the slit 12. Then, together with the screw 13, the joint 10 coupled to the screw 13 similarly moves, 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 into which the screw 13 was inserted when the joint 10 was stored moves along the linear 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 opposite to the 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 places of the screw 13 and the screw 16, and the rear handrail 6 and the side handrail 7B are substantially It is connected continuously. That is, the connection surface 17 of the rear handrail 6 and the side handrail 7B is fixed via 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 accommodated inside the side handrail 7B will be described next, 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 worker can move the joint 10 along the slit 12 by pinching the screw 13. When the screw 13 is moved to the screw hole 11a provided in the side handrail 7B, the joint 10 is completely housed inside the side handrail 7B. In this state, by fixing the screw 13 to the screw hole 11a, the joint 10 is fixed in a state stored in the side handrail 7B.

  In the above-described embodiment, the slit 12 is provided 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 movement of the joint described above. The same applies to the fixing holes 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 there is no hindrance to the movement of the joint 10, and the bolt 14 provided at the other end of the support bracket 5 is used. The side handrail 7B can be fixed to the side plate 3B by utilizing it. If at least the bolt 14 side of the support bracket 5 is fixed to the side plate 3B in advance and then the car 22 is assembled, the side handrail 7B idles only the main body side of the support bracket 5 from inside the car and inserts it 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, each component of the handrail can be easily carried in from the entrance 1 before being connected. In addition, even if the handrails are arranged in three directions in the car, the divided portions of the handrails are considered to be positioned not in the corner portions of the handrail but in substantially linear portions. Therefore, the joint 10 is used, in which the straight end of the rear handrail 6 and the straight ends of the side handrails 7A and 7B are disposed opposite to each other and moved coaxially with the connecting portion. The work efficiency can be improved without increasing the number of connection points. Moreover, it can be set as the handrail which maintained the designability also as a whole, maintaining the designability of a connection part.

  In this way, the entire handrail is connected as if it were a continuous integral construction, so that the outer surface can be made smoother. Therefore, when a wheelchair user or the like moves in the car while being caught by the handrail, it can smoothly move in the car without being restricted using the uninterrupted handrail, so that the user has an excellent feeling of use. There is no risk of injury or discomfort to the user.

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

  The present invention is not limited to the embodiments described above, but includes various modifications. For example, the embodiments described above are described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the configurations described. Also, 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. In addition, with respect to a part of the configuration of each embodiment, it is possible to add, delete, and replace other configurations.

  Specifically, in the above-described embodiment, the handrail is divided into the three members of the rear handrail 6 and the side handrails 7A and 7B, but the number of constituent members and the specific shape are limited. It is not something to do. For example, the curved portions may be integrally formed in advance in the side handrails 7A and 7B, and the rear handrail 6 may be configured substantially linearly.

  Further, in the above-described embodiment, the joint 10 is housed inside the side handrail 7B, but the cylindrical joint 10 movable in the axial direction may be provided outside the side handrail 7B. Instead of the side handrails 7A, 7B, the joint 10 can be provided inside the rear handrail 6.

  Furthermore, if the rear handrail 6 and the side handrails 7A and 7B are attached to the support bracket 5 so that position adjustment is possible, the rear handrail 6 and the side handrails 7A and 7B should be disposed in close proximity. As the moving joint 10 can be moved smoothly, the feeling of use, the designability and the manufacturability of the connecting portion 8 can be further improved.
