The position indicator 1b and the call button 1c are accommodated in the case 1f, and the position indicator 1b and the call button 1c are exposed by the front plate 1a.

The cable processing apparatus of the elevator of this embodiment connects the cable 3 which extends in a hoistway with respect to said position indicator 1b and the call button 1c. Mainly based on FIG. 3 and FIG. 4, the detail of the cable processing apparatus of the elevator which concerns on this embodiment is demonstrated. Fig. 3 is a perspective view of the cable processing apparatus seen from the hoistway side, and Figs. 4A, 4B and 4C show the hoistway side, the side and the bottom of the cable processing apparatus of the elevator according to the first embodiment, respectively. It is a figure which shows the state seen from the.

The cable processing apparatus 10 includes a wiring cover 4 as a supporting member for holding the cable 3 and a case 1f as a base to which the supporting member is fixed. In addition, the wiring cover and case are an example of a support member or a base. Therefore, the present invention may be applied as a support member or base for a wiring cover or case having a structure different from that shown in the present embodiment, and is carried out with the support member or base as a target that is completely different from the wiring cover or case. You may.

At least one of the support member and the base, that is, the present embodiment, is provided with at least one projection portion including an enlarged diameter portion having a diameter larger than the diameter of the base portion. Specifically, a fastening member can be used as the protrusion, and in this example, two screws 4a are used as the fastening member. The screws 4a each have a screw shaft portion 11 as a root portion and a screw head 12 as a diameter expanding portion. The screws 4a are each screwed from the case 1f side (destination side) to a portion of the wiring cover 4 that faces the case 1f.

On the back surface of the case 1f (surface on the hoistway side), a rectangular wiring hole 1g is formed as a communication window for passing the cable 3 through. The wiring hole 1g is covered from the hoistway side by the wiring cover 4 which fixes the cable 3 for connecting to the position indicator 1b or the call button 1c, whereby dust, water, etc. Intrusion into the case 1f through 1g is prevented.

In addition, in the case 1f, two fixing holes 13 through which the screw 4a is inserted are provided in the case 1f corresponding to the screw 4a. The fixing hole 13 has the passage part 14 and the holding part 15, respectively. The passage portion 14 is formed larger than the holding portion 15. Specifically, the passage portion 14 is sized to penetrate the screw head 12 of the screw 4a. The holding portion 15 has a size that the screw head 12 of the screw 4a cannot pass through and the screw shaft 11 can penetrate.

The passage portion 14 and the retaining portion 15 will be described in more detail. First, the first fixing hole 13 is located above the wiring hole 1g, and the passage portion 14 is composed of a large diameter round hole, and the retaining portion 15 is formed of the passage portion 14. It consists of a small diameter round hole connected with the said round hole of the said large diameter so that it may overlap with the round hole of a smaller diameter than a large diameter round hole. On the other hand, the 2nd fixing hole 13 is comprised using the wiring hole 1g. That is, the passage part 14 of the 2nd fixing hole 13 is the wiring hole 1g itself which is a large diameter angled hole, and the holding part 15 is the lower angle part of the wiring hole 1g. Is composed of a small diameter round hole connected to the wiring hole 1g.

3 and 4, in each of the fixing holes 13, the holding portion 15 is located below the passage portion 14. In particular, in this embodiment, each holding | maintenance part 15 is arrange | positioned obliquely under the corresponding passage part 14. As shown in FIG.

Next, the connection of the wiring cover 4 and the cable 3 is demonstrated. The cover 4 for the wiring 4 is opened downward and protrudes toward the hoistway side. The groove 4b for introducing the cable 3 into the case 1f is formed in the surface of the boarding point side in this cover part 16. As shown in FIG. The cable 3 is arranged inside the cover portion 16 and guided up and down by the cover portion 16.

Moreover, as the outer surface (surface of the hoistway side) in the wiring cover 4, the cable fixing clamp 4c is attached to the lower part of the cover part 16. As shown in FIG. Most of the cable fixing clamps 4c are arched, as is particularly shown in Fig. 4C. One end of the cable fixing clamp 4c is hung from the hoistway side of the wiring cover 4 via an opening in the lower portion of the lid portion 16 or a dedicated through hole, and the other end of the cable fixing clamp 4c is fastened. It is fixed to the cover 4 for wiring by the means 4d. The cable 3 is sandwiched and fixed between the arch inner surface of the cable fixing clamp 4c and the outer surface of the wiring cover 4.

Next, the mounting procedure to the case of the wiring cover comprised as mentioned above is demonstrated. First, the wiring cover 4 is disposed near the case 1f in a state where the cable 3 is fixed to the wiring cover 4 by using the cable fixing clamp 4c. In addition, although the two screws 4a are attached to the wiring cover 4, at this time, the screw head 12 of each screw 4a has a predetermined distance from the surface of the landing side of the wiring cover 4 ( For example, the thickness of the case (about +1 mm) is kept in a floating state.

Then, the wiring cover 4 in the above-described state is inserted into the passage portion 14 of the corresponding fixing hole 13 by the two screws 4a and brought to the case 1f. At this time, since the screw head 12 is in a state of floating from the surface of the wiring cover 4 as described above, the screw head 12 exits the passage portion 14 of the fixing hole 13, and the screw shaft portion is provided in the fixing hole 13. (11) is located. Further, the tip of the cable 3 extends out of the wiring hole 1g and sufficiently reaches the position indicator 1b and the call button 1c. In other words, it is assumed that the wiring hole 1g, the fixing hole 13, and the screw 4a described above are provided in a relation, position, and form such that such a state is obtained.

Thereafter, the wiring cover 4 slides obliquely downward with respect to the case 1f, and the screw shaft portions 11 of the two screws 4a are positioned at the holding portions 15 of the corresponding fixing holes 13. Do it. As a result, the screw head 12 of the screw 4a is caught by the holding portion 15 of the fixing hole 13, and the wiring cover 4 is supported so as not to be spaced apart from the case 1f. The wiring cover 4 is temporarily fixed.

After that, by connecting the connector of the cable 3 with the position indicator 1b and the call button 1c on the landing side, and tightening each of the screws 4a which are screwed to the wiring cover 4 sufficiently firmly. This fixing to the case 1f of the wiring cover 4 is completed. In addition, the connector connection of the cable 3 and this fixation of the wiring cover 4 may be started either any first, and either may be finished first.

According to the cable processing apparatus of the elevator according to the present embodiment as described above, since the wiring cover can be temporarily fixed to the case of the operation display mechanism only by hanging the projection part in the fixing hole, the operator places a rigid position such as a screw hole from the hoistway side. It is not necessary to perform work called a fitting operation or a subsequent screwing operation. That is, in a hoistway with a lot of work space restrictions, only the task of hanging the protrusions into a predetermined hole can be completed without the use of a tool, and thus the necessary work can be completed on the hoistway side. It can be easily attached to the object.

Moreover, since the fastening means screwed from the landing side side is used as a projection part, when screwing in the state which loosened the fastening member at the time of temporarily fixing, and fastening a fastening member firmly in the state which fastened the fastening member to the fixing hole, it will be seen as it is. Fixing can be performed. Therefore, a common means can be used for temporary fixation and this fixation, and the part score can be reduced. In addition, since the fastening means has already been set before the main fastening, there is no fear that the fastening means may fall before the fastening means is held in the hand and inserted into the screw hole. All you need is a simple tool with a common tool. Therefore, workability is extremely favorable.

Moreover, the hole provided in the case can be utilized by two functions, a hole (contact window) which guides a cable to an object, and a hole as a passage part for inserting the enlarged diameter part of a projection part. Therefore, since the passage portion does not have to be provided separately, the production and processing can be simplified, and the complexity of the structure can be avoided. Moreover, the space saving of the area | region required for forming a fixed hole can also be aimed at.

Moreover, since the protrusion part and the fixing hole are provided in multiple settings, rotation with respect to the case of the wiring cover is already suppressed in the step of temporarily fixing before this fixation, and it is possible to shift from temporary fixation to this fixation work in a stable state.

In addition, since the cable is guided to extend in the up and down direction by the cover portion of the wiring cover, the cable extending from the wiring cover to the hoistway is laid downward, that is, the cable is not extended vertically from the wiring cover so that the cable is not extended vertically. It can avoid escaping.

In addition, the cable is secured by being pushed by the cable fixing clamp in the state where it is guided to the cover part, thereby preventing the cable from rattling against the outer surface of the wiring cover, so that the cable remains in the desired state within the cover part. Can be.

Embodiment 2 Fig.

Next, based on FIG. 5 and FIG. 6, the cable processing apparatus of the elevator which concerns on Embodiment 2 is demonstrated. (A), (b) and (c) are the figures which showed the state seen from the hoistway side, the side, and the bottom with respect to the cable processing apparatus of the elevator which concerns on Embodiment 2, respectively, and FIG. 6 is Embodiment 2 It is a figure which shows the fixed spring provided in the cable processing apparatus of the elevator which concerns on.

This Embodiment 2 improves the structure which concerns on a fixed clamp in Embodiment 1, and may be set as the structure similar to Embodiment 1 about another part. The cable processing apparatus 20 is provided with the plate-shaped fixed spring 5. The fixed spring 5 is attached to the inside of the cover portion 16 in the wiring cover 4.

The fixed spring 5 has a semicircular cable pressing part 5a and a pair of left and right peaks 5b positioned at both ends thereof. In addition, a plurality of pairs of insertion holes 4e into which a pair of peaks 5b are inserted are formed in both side portions of the cover portion 16 of the wiring cover 4.

The fixed spring 5 has a right and left pair of peaks 5b inserted into the corresponding pair of insertion holes 4e of the cover portion 16 so as to be more curved than a natural state, and the cover portion is formed by its elastic restoring force. It is attached to (16). The fixing spring 5 fixes the cable 3 by sandwiching the cable 3 between the inner surface of the cover portion 16 as shown. Moreover, the size of the space which arises between the fixed spring 5 and the inner surface of the cover part 16 can be changed by changing the pair of insertion hole 4e of the object which inserts a pair of mountain part 5b. Can be.

In the elevator cable processing apparatus according to the second embodiment as described above, similarly to the first embodiment, the cable extending in the hoistway can be easily attached to a predetermined object. In the second embodiment, by using the elastic restoring force of the fixing spring, the fixing spring itself can be held and the cable can be fixed, so that the number of parts can be reduced and the fixing spring can be easily removed. In addition, since the fixed spring is mounted using elastic restoring force, it is easy to change the mounting position. In addition, the fixing spring can be expected to generate deformation and restoring force at the time of fixing, having one fixing spring, can cope with the fixing of the cable of different thickness, and also leads to the reduction of the type of fixing spring to be prepared.

Embodiment 3:

Next, based on FIG. 7, the cable processing apparatus of the elevator which concerns on Embodiment 3 is demonstrated. FIG.7 (a), (b) and (c) is a figure which shows the state seen from the hoistway side, the side, and the bottom about the cable processing apparatus of the elevator which concerns on Embodiment 3, respectively.

In the third embodiment, the configuration related to the fixing tool is also improved in the first embodiment, and other portions may be the same as the first embodiment. The cable processing apparatus 30 is provided with the fixed wire member 6. The fixed wire member 6 is, for example, a string-like member such as a bind wire, and is wound around the cover portion 16 in the wiring cover 4. Through-holes 4f are formed in both side portions of the lid portion 16. Moreover, 4 g of long holes are provided in the upper part which concerns on the protrusion of the cover part 16. As shown in FIG.

The fixed wire member 6 extends to sew the inside and the outside of the lid part 16 by inserting the right and left through holes 4f alternately. As a result, the fixing wire member 6 fixes the cable 3 by sandwiching the cable 3 between the inner surface of the lid portion 16 as shown. As an example, the fixed wire member 6 is prepared to some extent in advance, and the winding is performed using the length corresponding to the thickness of the cable 3 to be fixed, and the remaining length is cut off after the winding. You may also

In addition, when the fixing wire member 6 is wound around the lid portion 16, the fixing wire member 6 is caused to fall into the long hole 4g. Thereby, the fixed wire member 6 is caught by the long hole 4g, and the position shift of the fixed wire member 6 with respect to the cover part 16 can be prevented.

In the elevator cable processing apparatus according to the third embodiment as described above, similarly to the first embodiment, the cable extending in the hoistway can be easily attached to a predetermined object. Moreover, in Embodiment 3, since the length of use in a fixed wire member changes only with a situation, it is only necessary to prepare what is long enough string shape as a member, and it does not need to prepare many variations as a fixed wire member, It can cope with the fixing of the cable over the thickness of the cable.

As mentioned above, although the content of this invention was concretely demonstrated with reference to preferable embodiment, it is clear that those skilled in the art can acquire various modified forms based on the basic technical idea and teaching of this invention. .
