Abstract

(57) [Abstract] [Purpose] To prevent wear of moving contacts of elevator floor selection device and prevent contact failure. [Structure] An oil-impregnated member 3 is interposed in an arbitrary gap between fixed contacts 1 arranged vertically and slidably contacted with the oil-impregnated member 3 by moving a movable contact 2 up and down. As a result, the movable contact 2 is automatically wiped and lubricated to prevent abrasion.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator floor selection device.

[0002]

[Prior art]

 2 and 3 are sketches of an elevator floor selection device disclosed in Japanese Utility Model Laid-Open No. Sho 58-34861, in which 1 is intermittently distributed in the upward and downward directions according to the elevator stop floor. The fixed contacts 2 provided are movable contacts that move in conjunction with the vertical movement of the car, and are configured to sequentially contact the fixed contacts 1.

[0003]

[Problems to be solved by the device]

 By the way, the movable contact has a structure that always receives a small amount of elastic pressure from behind, and as a result of repeated contact and sliding contact with the fixed contact depending on the operation of the elevator, its tip end wears out and eventually Contact failure will occur. To prevent this, the movable and fixed contacts are wiped and lubricated during maintenance inspections, but in the case of an elevator with frequent operation, it is desirable to take measures to prevent the above-mentioned wear between regular maintenance inspections. . The above-mentioned conventional technology has a problem that this point is not sufficiently taken into consideration.

An object of the present invention is to provide an elevator floor selection apparatus which is effective in solving the above problems and which is excellent in maintainability.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a fixed contact which is intermittently arranged in the vertical direction according to a stop floor of an elevator, and a fixed contact which is sequentially contacted with the fixed contact in association with the vertical movement of a car. In an elevator floor selection apparatus including movable contacts in contact with each other, the movable contact lubricating oil-impregnated member is interposed in an arbitrary gap between the fixed contacts arranged above and below.

[0006]

[Action]

 According to the present invention, the movable contact that is interlocked with the vertical movement of the elevator automatically slides into contact with the oil-impregnated member, which has the effect of playing a part of the contact maintenance work until the next maintenance.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a side view of a main part (A portion in FIG. 2) of a floor selection device of an elevator. In the figure, 3 is an oil-impregnated member mounted so that a movable contact 2 slides between upper and lower fixed contacts. The other reference numerals indicate the same parts as in FIGS. 2 and 3.

[0009]

[Effect of device]

 According to this invention, the movable contact that is interlocked with the vertical movement of the elevator automatically comes into sliding contact with the oil-impregnated material, which has the effect of playing a part of the contact maintenance work until the next maintenance.
