The present invention relates to a manual switch of the type which, by selection, makes it easy to operate in any given direction, but minimizes accidental operation in this direction.

An emergency stop switch is required in the elevator, which, when activated, causes power to be removed from the elevator drive motor and brake of the gun elevator, or from the electrically operated valve and pump motor of the hydraulic elevator. Co-trial US application serial no. 941,617, filed on September 12, 1978, cited an example of an improved pushbutton assembly that has many advantages for use as an elevator call button at a call location installed in an elevator. . The housing of this pushbutton assembly is mechanically strong and not only looks good, but it is also designed to withstand accidental and random abuse. In addition, the nameplate was engraved directly on the user's left side of the push plunger of the push button assembly to aid visual impairment.

Emergency stop switches are usually installed on the control panel such as elevator call push buttons. This known emergency stop switch is insufficient to be installed in the same place as the push button assembly, as well as coinciding with the actual position of the confirmation nameplate and the actuating part of the push button assembly to aid visual disturbances.

In the prior art, the operation toggle of the emergency stop switch is usually in the form of a handle or lever, in order to distinguish it from an elevator call push button with a responsive actuating part, and usually made of red material to also indicate its slander features. .

The primary purpose of the present invention is to further emphasize its emergency features, reduce the likelihood of accidental operation caused by the actuating part on clothes or briefcases, and also provide a control panel to find a nameplate for visually impaired people to check elevator call push buttons. It provides an improved emergency stop switch that reduces the likelihood of accidental operation.

In view of this object, the invention resides in a switch that facilitates operation by selection in a raised direction while minimizing accidental actuation in this direction, the switch being generally flat and vertically oriented front surface. And a housing having an inner side, an electrical contact assembly mounted in the housing and operable between the first and second positions, and an actuating portion mounted in the housing behind the front housing surface on a horizontally oriented pivot axis. And the actuating portion has a first portion that is easily accessible from the outside of the housing and a second portion in the housing that is operatively connected with the electrical contact assembly. The first portion has a generally spherical contour with recesses for pivotally actuating the actuating portion between first and second angular positions that respectively select first and second positions of the electrical contact assembly.

And the recessed portion of the first portion of the actuating portion is adapted with a horizontally oriented pivot axis selected to facilitate operation by selection to a second position and allow the area of the second generally flat surface to exceed the area of the first generally flat surface. Set with different spacings, each comprising first and second generally flat and intersecting surfaces for operating the actuator in the first and second positions, the first and second planes being oriented relative to one another; It is generally oriented with respect to the pivot axis of the spherical contour so that the first plane of the recess is at approximately the same plane as the front face of the housing, and the lowest edge of the second plane is in the second state when the actuator is in the first angular position. Operation of the actuator into the second position by excluding the force exerted on the actuator in a direction perpendicular to the front surface of the housing To minimize the action is placed on the pivot axis.

The present invention will become more apparent from the following illustrative description, in conjunction with the accompanying drawings.

In short, the present invention shows an improved manually operable switch comprising a pivotally mounted actuating portion and an electrical contact assembly. At least the accessible part of the actuating part has a spherical face recess (concave part) which causes the actuating part to move between the first and second angular positions of operating the associated electrical contact assembly in the first and second positions, respectively. It is a spherical shape.

The recess is formed by intersecting first and second planes to define a set angle between the generally flat first and second planes. This set angle relates to the travel (movement) angle of the actuator between the two angular positions, preferably equal to 180 ° minus the travel angle.

This relationship causes the first plane of the recessed portion to be oriented in a direction perpendicular to the first angular position of the actuating portion, and the second plane of the recessed portion is oriented in a direction perpendicular to the second angular position of the actuating portion.

The first and second planes have a first upper limit measured relative to the pivot axis of the actuator with the intersection of the first and second planes occurring at the first angular position above the pivot axis and the first and second planes selected. Intersect the faces of the spherical shapes in.

The relative portions of the first and second planes, the position of the plane with respect to the pivot axis, and all of the concrete structures are coordinated to suppress accidental actuation from the first angle position of the actuating portion to the second angle position.

Referring to FIG. 1, a switch assembly 10 constructed in accordance with the techniques of the present invention is shown. The switch assembly 10 includes a housing 12 having a front portion 14, a cylindrical groove 16 extending from the front portion 14 to a hole defined by the housing 12, and an actuating portion 20. It is included.

The actuator 20 is pivotally installed in the cylindrical groove 16 by a pivot pin 22 coaxial with the horizontal pivot shaft 24.

For purposes of illustration, the housing 12 is illustrated similarly to the push button housing shown in the above cited US application, which is incorporated by reference for a more complete understanding of the housing details used to construct the switch assembly 10.

However, it should be understood that the present invention can be applied to any manual switch having an actuating part that is pivotally installed.

The front portion 14 of the housing 12 is spaced horizontally away from the first projection 26 and the first projection 26 having a front face 27 surrounding the front opening for the cylindrical groove 16. A second projection 28 and a name plate 30 disposed between the two projections on the left side of the actuating portion 20 as shown in FIG. The name plate 30 includes an embossed portion 32 that shows the visually impaired function of the switch assembly 10. The illustrated “×” indicates that the switch assembly 10 is an emergency stop switch for use in an elevator, and the switch assembly is not limited to this application.

The name plate 30 is pinned by the pins 34 and 36, and each pin is fitted into the straight holes of the second protrusion 28, the name plate 30, and the first protrusion 26, and is assembled in the assembled position. It is pinned.

The actuating part 20 is a first part 40 accessible from the front of the housing 12 and a second part in the hole of the housing 12 as well shown in FIGS. 3 to 7. It contains (42). At least the first portion 40 has a spherical shape 44 in which a spherical shape is formed to enable the actuating portion 20 to be operated between the first angle position shown in the first degree and the second angle position shown in the second degree. With a spherical appearance.

FIG. 2 is a partial view of the switch assembly 10, similar to the switch assembly 10 of FIG. 1, except for the position of the actuating portion 20.

3 is a side view of the actuating portion 20 in each position shown in FIG. 1, and FIG. 4 is a rear view of the actuating portion 20 as illustrated in FIG. 3, and FIG. 5 is shown in FIG. Side view of the actuating section 20 at the respective positions. In the preferred embodiment of the invention illustrated in FIGS. 3, 4 and 5, the second part 42 of the actuating portion 20 is characterized by the electrical contact arrangement in which the actuating device 46 is specified or the switch mechanism used. In addition to the spherical structure for interaction with each other, the spherical structure of the first portion 40 continues. The continued spherical structure has a number of advantages, including providing the necessary operating spacing for the actuator 20 to pivot within the cylindrical groove 16.

The actuating portion 20 has an opening 48 accessible from the second portion 42, with the pivot shaft pin 22 extending between the sides of the actuating portion defining this opening.

As illustrated in the figure, the horizontal pivot axis 24 crosses the center of the spherical structure.

The first and second stop portions 50 and 52 are horizontally spaced opposite the opening 48 so that the stop portions 50 and 52 extend outward of the cylindrical structure of the cylindrical groove 16. Touches the inner wall 54 of the front portion 14 at both respective positions of the actuating portion 20 in order to determine the travel limit of the actuating portion 20.

An actuating pin 56 extending between the spaced stops 50 and 52 is provided coaxially with the horizontal axis 57. The actuating pins 56 are coordinated with the actuating mechanism of the electrical contact assembly or the switch mechanism, as will be explained next with reference to FIGS. 6 and 7.

The first and second electrical contact actuators extend outwardly from the horizontally spaced first and second stops 50 and 52, respectively, the purpose of which also relates to FIG. 6 and FIG. Will be explained.

The recess 44 has a structure related to the traveling angle of the actuating unit 20.

As illustrated in FIGS. 3 and 5, the advancing angle is the angle between two positions of the centerline 62 intersecting the sides 24 and 57, and between the third degree centerline 62 and the horizontal line 66. FIG. Including an angle 64, the angle 68 is included between the centerline 62 and the horizontal line 66 of FIG. 5. For purposes of poetry, the angles 64 and 68 were each chosen to be about 30 °, so that the advancing angle of the actuating portion 20 is about 60 °.

The recess 44 includes first and second planes extending inwardly from the spherical surface of the first portion 40 and intersecting with each other, the intersection of the surfaces having an angle 74 equal to 180 ° minus the advancing angle. Form.

As such, in the example given the advancing angle of about 60 °, the angle 74 between the intersecting faces 70 and 72 of the spherical actuation sphere is 120 °.

The arrangement of the first and second planes 70 and 72 is such that they are chosen to have different areas and the intersection with the outer surface of the spherical structure of the flat surface is also shown in FIGS. 20, and the second angular position of the actuating portion 20 shown in FIGS. 2 and 5 has been selected to occur at the designated position.

Their placement criteria include the following conditions;

(1) The first plane 70 should face perpendicular to the face of the front portion 14 of the housing 12 at the first angular position of the actuating portion 20 and the second plane 72 of the actuating portion 20 It should face vertically at the second angle position.

(2) The intersection of the spherical structures of the first and second planes 70 and 72 should occur around the pivot axis 24 (measured, within a single 90 ° arc or quadrant.

(3) The intersection of the spherical structures of the first and second planes 70 and 72 should occur on the pivot axis 24 when the actuating portion 20 is at the first angled teeth shown in the first and third degrees. do.

(4) The area of the second plane 72 for operating the switch assembly from the first angular position of the actuating portion 20 to the second angular position is such that the actuating portion 20 is moved from the first angular position to the first angle. It should be larger than the area of the first plane 70 tripping to the angular position.

Condition (1) directs the manual operating pressure to an appropriate surface and completes the travel angle without either surface being retracted into the cylindrical groove 16. It is also most apparent when the nameplate arranged on either or both surfaces is in position with the switch in relation to the vertically facing surface. For example, as shown in FIG. 1, when the switch assembly 10 is used as an emergency stationary switch, a name plate of "stop" may be engraved on the second plane 72. A plate called "moving" may be engraved on the first plane 70.

It will be noted that the position of the switch assembly 10 is automatically marked by the relative size of the two plates in the vertical direction.

If the nameplate is only used on one surface, the angle of the surface also indicates the nameplate indicating the switch position. This condition is achieved by forming the angle 74 at an angle minus the advancing angle at 180 °.

Condition (2) maintains a large portion of the spherical surface of the first portion while providing a suitable surface area for actuation of the actuating portion 20.

The large spherical surface causes an accidental force exerted on the actuator 20.

Condition (3) results from the force exerted on the actuator from tripping the actuator 20 from the first angular position shown in FIGS. 1 and 3 to the second angular position shown in FIGS. In a direction perpendicular to the front portion 14 of the housing 12. When used as an emergency stop switch for a car, the first angle position is the "move" position and the second angle position is the "stop" position. Accidental stop of the elevator is avoided.

The condition (4) provides a relatively large surface to actuate from the first to the second angular position of the actuating section 20 if an emergency occurs and such action is intended.

Conditions (2), (3) and (4) indicate that the distance 80 from the vertical centerline 82 shown in FIG. 3 is equal to the second plane 72 and the vertical centerline 82 shown in FIG. It is provided by forming the first plane 70 to be smaller than the gap 84 with.

In the first angular position shown in FIG. 3, the lowest edge 86 of the second plane 72 is preferably shown as being as high as a specified size 88 than the horizontal line 66, but the edge 86 is shown. Note that it is also appropriate to lay as low as this horizontal line 66.

When the first plane 70 is oriented vertically, it is substantially flush with the front face 27 of the protrusion 26, and when the second plane 72 is oriented vertically, the second plane 72 is turned to the front ( Note also that it is spaced out from 27. This arrangement adds to the difficulty of accidental operation of the switch assembly 10 from the first angle position shown in FIG. 3 to the second angle position shown in FIG.

FIG. 6 is a longitudinal sectional view, taken between and in the direction of arrows VI-VI, of the switch assembly 10 shown in FIG. 1, and FIG. 7 is an arrow VIII- of the switch assembly 10 shown in FIG. It is a longitudinal cross-sectional view taken in the direction of and between them. 6 and 7 illustrate the actuating portion 20 fluidly coupled to the electrical contact assembly 90 of the switch device used.

However, the electrical contact assembly 90 is shown by way of example only and many other actuation mechanisms may be used. The electrical contact assembly 90, in this example, comprises a U-shaped structure 92, the leg portion of which is an overcurrent toggle structure pivotally mounted on a common horizontal pivot axis 94.

At the bend of the U-shaped structure 92 is a first spring seat 96. The second spring seat 98 is mounted on the operating plate 56 and the helical spring arrangement 100 extends between the first and second spring seats 96 and 98.

The helical spring 100 is slightly compressed, which springs incline or hold the second spring seat 98 relative to the actuating pin 56. The stop devices 101 and 103 restrict the stroke of the U-shaped structure 92.

In the first angular position of the actuator 20, shown in FIG. 6, the contact actuators 58 and 60 apply pressure to the common conductive connection 102, respectively, to overcome normal upward deflection and to move downward. Bend to

In this way, the electrical contacts of the conductive connection 102 may be separated from the associated fixed contacts, such as for example 104 the fixed contacts 106. As illustrated, the state of the additional contacts, such as the contact pair 108 including the fixed contact 110 and the movable contact 112, does not change at this position, so it is normally shorted.

When the second plane 72 is pressed in the downward direction, the helical spring 100 stops the U-shaped structure 92 from the position shown in FIG. 6, with respect to the stop 101. Driving to the position shown in the seventh, which is stationary relative to 103, the spring action causes the actuating portion 20 to continue turning once it reaches a specified angular position, the rear wall 54 of the front portion 14 of the housing. It causes the two stops of the actuating part 20 to act on the associated stops formed by them.

The contact actuators 58 and 60 thus fall away from the conductive connection 102 and the springing of this part causes the contacts involved to return and engage with their fixed contacts. The contact constructions 58 and 60 apply pressure to the connection with the moving contact of the additional contact device, such as the movable contact 112 of the contact pair 108, to separate them from their associated fixed contacts 110.

The upward pressure of the first plane 70 sufficient to rotate the actuator 20 by the specified angle around the horizontal pivot axis 24 will return the switch assembly to the position shown in FIG.
