The present invention relates to a passenger handle of an elevator, specifically, a length-adjustable elevator that can be easily installed while promoting the safety of the operator inside the elevator cage, and can also adjust the distance of the handle to the elevator wall Relates to a passenger handle.

In general, the following three methods are generally used as a conventional method of installing a passenger handle installed on an inner wall of an elevator in an elevator cage.

1 is a cross-sectional view of a typical elevator, in which a passenger and a handle are shown.

As shown in the drawing, a handle 10 having a cylindrical shape or the like is generally attached to the inner wall of the elevator in a horizontally long position at a position suitable for a passenger's hand. Such a handle 10 is supported on the inner wall of the elevator by brackets 20 arranged at appropriate intervals in the longitudinal direction thereof, and is generally coupled to the elevator wall by fasteners 30 such as bolts connected to the brackets. .

2 shows an example of a conventional handle assembly in an enlarged cross sectional view.

As shown in the figure, one end of the bracket 20 has a fastener 30 such as a bolt, and the fastener penetrates through the elevator wall 1 and protrudes to the outside, and is fastened with a washer, a nut, etc. from the outside of the elevator. Tightening the sphere 30 is to fix the handle 10. In the assembling work, such a handle is generally installed after completing the interior decoration of the elevator cage and installing the elevator cage in the lifting passage. However, in this work, since the interior installer, who is not skilled in the elevator installation work, needs to go out of the elevator and work, there is a risk of the worker falling from the elevator suspended in the air.

3 is a cross-sectional view of a combination of another conventional handle assembly.

As shown, in this case there is a U-shaped cap 25 surrounding the bracket. The cap 25 is sized to have a predetermined space formed therein while being coupled to the bracket 20. Therefore, in the elevator, the cap 25 is first coupled to the elevator wall with a fastener 30 such as a bolt, and then the handle bracket is inserted into the cap 25, and the bracket is inserted into the cap 25 with the bracket inserted. When tightening with a small screw or the like, the handle assembly is completed.

However, such a handle assembly is coupled to the bracket and the cap by using a small screw, so the long-term use of the combination of the cap and the bracket is loose, the handle is often used to shake the handle. In addition, since there are many handle brackets (usually 3-4 pieces), there is a problem that it is difficult to align the cap and the fastener holes preformed on the elevator wall.

Figure 4 is a side view of a disassembled state of the handle assembly of another conventional example.

As shown, in this case, the fastening plate 50 is joined to one end of the bracket 20 by welding, and the fastening plate 50 is coupled to the elevator wall with a fastener. In this case, assembling of the handle can be performed inside the elevator, and the safety of the worker can be secured. However, since the fastening plate 50 itself protrudes to both sides of the bracket 20, it is visible from the outside. Will be exposed to the field of view. Since it is a serious problem that the fastening plate is exposed to the outside in an elevator that emphasizes the interior decoration, such a handle assembly is rarely used in an elevator that emphasizes the interior.

The present applicant has filed a utility model on December 23, 2002, elevator handle improved workability in view of such a conventional problem.

5 is a cross-sectional view showing this conventional invention of the applicant. In this invention, the bolt 30 is fixed to the exterior of an elevator, and inside a elevator, the nut inside a handle is fixed by turning. However, this invention has to be shipped by fixing the bolt on the elevator wall in advance in the elevator shipment factory, causing the scratches on the other wall boards stacked by the bolts protruding when the wall boards stacked, and the bolts in advance in the wall board There is a problem that it is difficult to fix. In addition, there is a problem in that it is inconvenient to fasten the washer and nut to the bolt through the inside of the handle.

In addition, none of the above-described prior art uses a machined handle to form an opening, and generally does not use a commercially available cylindrical body as it is, so that a separate processing cost or material cost is high. There is.

In order to improve this problem, the present applicant has filed a handle assembly as shown in FIG. 6 as Utility Model Registration Application No. 9996 on April 12, 2004.

The utility model registration application was devised in view of the conventional problems, and it is possible to secure the safety of the worker by allowing all operations to be performed inside the elevator cage without fixing bolts on the elevator wall in advance in the production plant of the elevator. Of course, the fasteners are not exposed to the outside, so as not to impair the aesthetics of the interior decoration of the elevator. An object of the present invention is to provide a handle assembly.

That is, as shown, a plurality of outer nuts are attached to each of the through holes on the outer surface of the wall surface 1 so as to be aligned with the plurality of through holes formed at intervals on the wall surface 1 of the elevator. The first fastener, such as a bolt, is connected to the outer nut 60 through the through hole of the handle rest end wall through the space of the handle rest 100, and then tightened with a wrench to secure the handle rest 100 to the elevator wall. To combine.

In the case of the handle assembly configured in this way, it is possible to secure the operator's stability by allowing all operations of coupling the elevator handles inside the elevator cage without fixing bolts on the outer wall of the elevator in the production plant of the elevator. The handle assembly for passengers of the elevator that is easy to maintain, such that the bulbs are not exposed to the outside, so as not to impair the aesthetics of the interior decoration of the elevator, and the combination state is so strong that the handles can be kept in spite of long-term use. Can be provided.

However, in recent elevators, it is common to attach a decorative plate therein. Some of these decorative plates are thin, but some are quite thick. When a thick decorative plate is attached to the inner wall of the elevator, there is a problem that the gap between the cylindrical handle and the decorative plate outer surface becomes narrow. Even when the passenger lifts the handle by hand, it may be inconvenient to sandwich the passenger's hand into the gap between the handle and the decorative plate. Therefore, the necessity of adjusting the length in the handle of an elevator is increasing. The length here means the length of the clearance gap between a handle and an elevator inner wall surface.

The present invention has been made in view of the above-mentioned problems in the prior art, and the length between the inner wall surface of the elevator and the handle can be arbitrarily adjusted as needed, while the length of the configuration can be adjusted so that the disassembly and assembly work can be conveniently performed inside the elevator. It is an object to provide a passenger handle of an elevator.

Provide a handle for

In the passenger handle of the elevator according to the present invention, the jaws 148 and 148 'are formed on the upper left and right sides of the lower horizontal walls 146 and 146' of the handle supports 140 and 140 ', and both jaws 148; The spacing between 148 'is preferably such that the rotation of the nut tightening the fastener 30 is prevented.

In addition, in the present invention, the lower vertical wall 125 protrudes at both ends of the lower horizontal wall 122 of the fixing table 120, and the length of the vertical wall 125 is greater than the height of the bolt head of the fastener 30. It would be more desirable to be able to cover the bolt head of the fastener in the assembled state of the cursor fastener.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 7 is a cross-sectional view of the handle assembly of the first embodiment according to the present invention, FIG. 8 is a cross-sectional view taken along line 8-8 of FIG. 7, and FIG. 9 is a cross-sectional view taken along line 9-9 of FIG.

As shown in Figures 7-9, the handle assembly of the present invention is a cylindrical handle (10) largely grasped by the passenger hand, the handle support 140 is coupled to the handle 10 at regular intervals, and the handle on the elevator wall Corresponding to the support 140 is fixed to the fastener is composed of a support 120 for receiving the handle support (140).

Fixture 120 is firmly fixed to the wall surface 1 of the elevator at a predetermined interval with a fastener 30 such as bolts. Of course, the holder 120 and the handle support 140 are paired with each other. The cross section of the fixing table 120 is preferably a semi-cylindrical shape, but may have other shapes such as squares and triangles. A horizontal wall 122 is formed at the lower end of the holder 120, and an opening 124 is formed over the entire length at the center of the horizontal wall. Since the handle support 140 must be coupled to the opening 124 by inserting a fastener such as a bolt as described below, the width of the opening 124 passes through a bolt column of the fastener 30 such as a bolt, but the bolt The head, etc., should not pass through. The length of the fixing rod 120, ie the length protruding from the wall surface can be appropriately set according to the size of the elevator.

Handle support 140 should be fitted to the corresponding support 120 in the state basically coupled to the handle (10). However, in the combined state, the handle support 140 should be slidable with respect to the holder 120. That is, the handle support 140 should be accessible to the appropriate length with respect to the holder 120 in a telescopic manner.

To this end, the cross-sectional shape of the handle support 140 is preferably a semi-cylindrical shape so as to be fitted to the holder 120 and slidably, but needless to say that it has a cross-sectional shape corresponding to the cross-sectional shape of the holder 120. . For example, if the cross section of the holder 120 is triangular, round, square, it should be a cross-sectional triangle, circle, square of the corresponding handle support 140.

The front end 142 of the handle support 140 is coupled to the handle 10, but may be coupled by welding or the like, but is preferably coupled by a fastener 30 such as a bolt. To this end, a vertical bulkhead 144 is formed in the front end portion 142 with a space 143 slightly inside, and the vertical bulkhead 144 has a through hole 145 through which a fastener 30 such as a bolt passes. It is good to be formed. If so configured, the handle support 140 can be firmly fixed to the handle 10 by using a bolt as shown.

In addition, a horizontal wall 146 is formed at the lower end of the handle support 140, and an opening 147 corresponding to the opening 124 of the fixing table 120 is formed in the center of the horizontal wall 146 over the entire length. Formed. Similarly, since the opening 147 cooperates with the opening 124 of the holder, the fastener must be inserted, so that the width of the opening passes through the bolt column of the fastener 30 but does not pass through the bolt head. In addition, the entire length of the handle support 140 is preferably longer than the fixed support 120.

In this case, when the supporter and the handle support are configured, the rear end portion of the handle support 140 is fixed in the state where the handle 10 is firmly fixed to the front end portion 142 of the handle support 140 by the fastener 30. Inserted into the inner space of the 120, and then fixed to the desired length through the lower opening 124 of the holder and the lower opening 147 of the handle support can be firmly fixed to the handle support with the fastener (30). . Therefore, the handle 10 can be fixed to the required length by using the fastener 30 in view of the thickness of the decorative plate attached to the elevator wall when installing the handle.

On the other hand, when fixing the handle support 140 to the holder 120, it is common to fix by rotating a bolt with a bolt. In this case, it is convenient to assemble the nut inside the handle support 140, and the jaw 148 is formed on the upper left and right sides of the lower horizontal wall 146 of the handle support 140 to prevent idle of the nut. It is desirable to. The interval between these jaws 148 may be sufficient to prevent rotation of the nut tightening the fastener 30. For example, in the case of a hex head nut, the distance between both jaws 148 may be set according to the gap between the opposite head surfaces.

In addition, for the aesthetic appearance of the interior of the elevator, it is preferable to make the above-mentioned fastener 30 invisible to the passenger as much as possible. To this end, the lower vertical wall 125 protrudes on both ends of the lower horizontal wall 122 of the holder 120, the protruding length is greater than the height of the bolt head of the fastener (30). In this case, since the bolt head of the fastener is hidden by the lower vertical wall 125 in the assembled state of the fastener, it is not visible to the outside, so as not to harm the aesthetics.

On the other hand, Figure 10 shows another embodiment of the present invention. 10 is a side cross-sectional view of the second embodiment, and FIG. 11 is a cross-sectional view taken along line 11-11 of FIG.

This embodiment is similar to the configuration of the first embodiment, but slightly different in the configuration of the handle support (140 '). In this embodiment, an arcuate recess for supporting the handle 10 separately is formed at the front end of the handle support 140 '. That is, the handle support 140 ′ is fitted to the holder 120 and is slidable and has a substantially semi-cylindrical cross section. One end coupled to the handle is substantially matched with the outline of the handle to support the handle 10 from below. An arcuate recess 142 'is formed. The horizontal bulkhead 144 'is formed in the recess slightly below the space 143' with which to place a nut, and a handle can be firmly fastened to a recess with a fastener. A horizontal wall 146 'is formed at the lower end over a part of the length of the semi-cylindrical part of a handle support, and the opening part 147' corresponding to the opening part 124 of a fixture is formed in the center. Of course, the width of the opening 147 'has a length such that the bolt head of the fastener 30 cannot pass. Other configurations are almost similar to those of the first embodiment, and thus detailed descriptions thereof will be omitted.

According to the present invention configured as described above, even when a thin or thick decorative plate or a decorative plate having irregularities on the surface is attached to the wall inside the elevator, the distance between the handle and the elevator wall can be adjusted to correspond to the thickness of the decorative plate. Passenger convenience can be achieved.
