INSTRUCTIONS (1) Technical field to which the invention pertains (please read the note on the back side and then fill out this page) The present invention relates to a pit or a lifting box provided at the lowermost portion of the lifting path of the elevator for A bumper for an elevator that absorbs the aforementioned lifting box or the weight of the counterweight. In the prior art, a general-purpose elevator damper (hereinafter, simply referred to as a damper) is used as a safety device for an elevator, and in order to ensure the safety of passengers when the lift box or the counterweight fails to stop at the lowest stage and rushes into the pit. The cushioning performance is required to be stopped at approximately the average deceleration of 1 G or less. In addition, it is required that the acceleration of 2.5G or more does not last for more than 0.04 seconds. That is, the buffer must be: stable at all times, and does not produce excellent shock performance with large acceleration. The structure of the conventional buffer is based on the rated operating speed of the elevator, and in the low speed field (generally 45 to 60 m/min or less), a spring type buffer is generally used, and in the lifting equipment exceeding the low speed field, Use a hydraulic buffer. The Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printed spring-loaded buffer is a shock absorber that absorbs the impact energy by the elasticity of the coil spring. The hydraulic shock absorber is inserted into the hydraulic cylinder by the piston. The regulating flap controls the resistance of the hydraulic oil encapsulated in the hydraulic cylinder to control the braking force, creating a mechanism for specific cushioning performance. However, the spring type damper has a problem of strength. The hydraulic type has a disadvantage that the free length becomes long due to its structure. In addition, the oil pressure damper is particularly difficult to avoid due to its structural relationship. This paper scale applies to the Chinese National Standard (CNS) A4 specification (210X 297 mm) -5 - 1246500 A7 B7 V. Invention description (2) Moreover, the requirements for the reduction of pits have recently increased, and the buffers have been miniaturized. It is a requirement to make the height of freedom smaller. Therefore, the inventors have considered that, for example, when the use of the field of use is different, a buffer having a corrugated buckling mode in the axial direction, which is proposed in Japanese Patent Laid-Open Publication No. SHO-50-61-181, may be provided. Known springs, hydraulic buffers, small, inexpensive buffers. Disclosure of the Invention [Problems to be Solved by the Invention] However, the damper for an elevator is one of important safety devices, and it is extremely important to be able to obtain the necessary cushioning characteristics frequently. In other words, in the buffer using compression, it is important to obtain stable load-displacement characteristics when the load is applied in the axial direction. In particular, in order to obtain a certain degree of displacement stroke, it is necessary to obtain a continuous and regular corrugated buckling displacement. However, in the above-mentioned proposal, for example, the seventh diagram of the explanatory diagram of the compression displacement when the cylinder 10 having the thickness of 2 mm and the load of the cylinder 10 is applied without the flange, and the explanation of the relationship between the load and the displacement will be described. As shown in Fig. 8, as the compression displacement continues, the deviation of the compression displacement shape due to the initial deformation of the cylindrical crucible is accumulated, and the load-displacement characteristic is deviated. In particular, 'when it is desired to obtain a long displacement stroke, this tendency is remarkably apparent, and 'because of becoming the elongated cylinder 10, the cylinder 10 is bent into a "letter shape" to produce Euler's buckling. There will be problems with a sudden drop in load. This is due to the fact that the cylindrical section is rapidly flattened and the rigidity in the section is weakened in one direction. This paper scale is applicable to China National Standard (CNS) A4 specification (210X297 mm) (please read the note on the back and fill out this page) • Installed by the Ministry of Economic Affairs Intellectual Property Bureau Staff Consumer Cooperative Printed -6- 1246500 A7 B7 , invention description (3) (please read the precautions on the back and then fill out this page) In addition, in the elevator buffer, the stroke of the bumper is extremely important. For example, when the stroke of the weight side buffer is greater than the plan , the lift box connected by the cable approaches the hoistway ceiling above the predetermined distance, and there is even a possibility of collision when the difference is made. In general, although the stroke size of the hoistway is provided with a certain margin, the demand for the hoistway reduction has been increased in recent years, and it is desirable that the strobe stroke does not exceed the plan 尽可能 as much as possible. After the compression displacement occurs continuously, when the portion that can be compressed is not available, it becomes a large load rapid action. The position of the folding point is in the configuration of the proposed example, compared to the deformed shape resulting from the initial deformation of the cylinder. The deviation is still large, and it is difficult to clearly determine the stroke schedule. In addition, a large load 产生 is generated at the beginning, which becomes an excessive acceleration to the lift box during buffering, which is not preferable. In this way, it is difficult to use the proponent as it is for the elevator buffer. It is an object of the present invention to provide a bumper for an elevator that can stably obtain a load-displacement characteristic and that is inexpensive and compact.

[Means for Solving the Problem] In order to achieve the above object, the present invention is provided under a pit or a lifting box at the lowermost portion of the lifting path of the elevator for absorbing the aforementioned lifting box or A damper for an elevator that has a heavy impact energy, wherein the damper for an elevator has a plurality of flanges, and a thin plate cylindrical portion is provided between the flanges, and when the damper is operated, the damper is operated. The cylindrical portion of the thin plate produces a corrugated buckling in an axisymmetric mode. -7- This paper scale is applicable to China National Standard (CNS) A4 specification (210X297 mm) 1246500 A7 B7 V. Invention description (4) (Please read the note on the back and fill in this page) So, because it can be convex Since the edge cylinder is a damper, it is possible to provide a smaller buffer than the conventional spring type or hydraulic damper, and it is possible to make the pit of the hoisting path shallow. In addition, it is much smaller and lighter than the conventional ones, and it can be installed under the lifting box and the counterweight. The machine in the pit is reduced, and the maintainability is also improved. EMBODIMENT OF THE INVENTION Hereinafter, a bumper for an elevator according to the present invention will be described based on an illustration of an embodiment. The first part of the elevator of the elevator damper to which the present invention is applied, and the second figure show the front view of the damper for an elevator according to an embodiment of the present invention. Fig. 3 is a view showing the relationship between the size of the buffer of Fig. 2, and Fig. 4 is an explanatory view showing the relationship between the load and the displacement when the buffer of Fig. 2 is operated, and Fig. 5 is a thin plate cylinder. Explanation of the displacement shape at the time of the corrugated buckling in the axisymmetric mode in which the two waves are generated, and Fig. 6 shows the displacement shape in the case of the corrugated buckling in which the one-wave axis-symmetric mode is generated in the cylindrical portion of the thin plate Figure. In Fig. 1, reference numeral 1 denotes a lifting path, and the lifting box 2 and the counterweight 3 are connected to the lifting path 1 by a cable 4, and are raised and lowered by the rotation of the pulley 5. The 6-series travels to a pit below the lifting path 1, where a buffer 7 is provided. Fig. 2 shows a specific configuration of the damper 7. The damper 7 is composed of a plurality of flanges 7 A provided at specific intervals and a thin plate cylindrical portion 7 B extending between the flanges 7A. Moreover, the overall size L of the buffer 7 and the inner diameter of 0 d -8 - the paper scale is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) 1246500 A7 B7 V. Invention description (5), thin plate cylindrical part The thickness t of 7B and the height h between the flanges 7A are as shown in Fig. 3. (Please read the note on the back and fill out this page.) The material of the bumper 7 is aluminum, which is JIS A 1 050 tempered material. The compression interval is set to 6 segments, and the thickness of the plate is gradually changed. In the present embodiment, as the upper portion of the oil flange goes down, the thickness of the plate is gradually increased. This is for the purpose of displacing the thin plate cylindrical portion 7 B in a very order. In addition, the load characteristics can also be controlled by variations in the thickness of the plate. In addition, h/t at this time becomes 0. 2 to 9.0. It can be seen from Fig. 4 showing the result of the actual test of the buffer of Fig. 2 that in the buffer 7 of the present invention, excessive load at the start does not occur, and continuous and stable compression occurs. Stable load characteristics are obtained. In addition, due to the change in the thickness of the plate, the average load gradually rises, knowing that the load characteristics can be controlled. Thereby, the buffer 7 having free buffering performance can be designed. In addition, knowing that the load-displacement characteristic increases as the displacement increases, the load rises sharply. The thin plate cylindrical portion 7B is all compressed, and the displacement portion is not changed. This is the same as the compaction state of the spring damper, and point A in Fig. 4 can be utilized to define the stroke of this damper 7. By this, it is possible to determine the clear stroke and stop the ride in the plan. The fifth figure shows the displacement shape when the thin plate cylindrical portion 7B causes the two-wave axisymmetric mode of the corrugated buckling 7C, and the sixth figure is shown in the thin plate cylinder. The portion 7B causes a displacement shape when the corrugated buckling 7C of the one-axis axisymmetric mode is generated. In addition, in the cylindrical portion of the thin plate, the relationship between the height h of the thin plate cylindrical portion and the thickness t when the corrugated buckling of one wave or two waves is generated is caused by the corrugated buckling 7D in which the one-axis axisymmetric mode is generated. In the case, if it is set to 0 < h/t < 9.8, when the corrugated buckling 7C of the axisymmetric mode of two waves is generated, it is set to 14.0 < h/t < 22 . In the case of 2 waves, with stroke 5 1 for full length can be compared to 1 -9- This paper scale applies Chinese National Standard (CNS) A4 specification (210X297 mm) 1246500 A7 B7 V.

On the other hand, in the case of one wave, as shown in Fig. 6, for the inner diameter of 0 d, there is a feature that the amount of expansion is small, for example, there is an advantage that the guide cylinder 8 can be passed through the center in order to restrain the buffer. . Further, in Fig. 6, the corrugated buckling is generated almost exclusively on the outer side of the cylindrical portion of the thin plate. According to the above embodiment, the flanged cylindrical body can be used as a damper, and it is possible to provide a buffer that is cheaper and smaller than the conventional spring type or hydraulic damper, and can also change the pit of the lifting path. shallow. In addition, compared with the conventional ones, it is very small and lightweight, and can be installed under the lift box and the counterweight, and the number of machines in the pit is reduced, and it is easy to ensure the moving line, and the maintainability is also improved. [Effects of the Invention] According to the present invention, it is possible to provide a buffer which is smaller and smaller than a conventional spring type or hydraulic type buffer, and which can shallowen the pit of the lifting path.
