Definitions
- the invention refers to a mechanical reset device for a switch, and it allows said reset to be realized from a location at a distance from the switch.
- the invention has been especially designed to reset switches located in inaccessible or hard-to-reach places.
- the invention is applicable to automatically triggered switches that are turned on by means of the angular displacement, in either direction, of a contact bridge and its support.
- elevators use speed limiters incorporating switches that turn on automatically when the elevator exceeds a certain speed. These switches are turned on through the angular displacement of the contact bridge, in one of two directions, depending on whether the elevator is going up or down, and to reset the switch, it must be accessed and manually turned in the direction opposite the contact bridge.
- Speed limiters for elevators are set in places that are hard to access, so resetting is complicated.
- the invention presents a totally mechanical device that makes it possible to reset a switch from a location at a distance from said switch.
- the device is totally mechanical, so that interruptions in electrical power do not prevent the reset from being effected.
- the invention is applicable to automatically triggered switches that are turned on by means of angular displacement, in either direction, of the contact bridge and its support.
- the invention is characterized in that the outside of the contact bridge support comprises at least one extension that, when the contact bridge is closed, is perpendicular to the direction of displacement of an actuator and is separated from the actuator by a certain distance.
- the actuator is connected to a remote handle so that it can be moved by operating said handle.
- the at least one extension consists of two pin-shaped extensions.
- the central branch of a T-shaped piece forming the actuator runs between these pin-shaped extensions.
- the pins shift angularly, so that, depending on the direction of rotation, one of the pins approaches the arms of the T-shaped piece and the other pin moves away from the arms.
- the reset is realized by operating the handle, which displaces the T-shaped piece, and one of the arms of this piece presses against the closest pin, forcing the contact bridge to return to its initial position, where the other arm of the
- T-shaped piece contacts the corresponding pin, producing the reset.
- the at least one extension consists of a small partition which, in the idle position, is located parallel to a small wall that comprises the actuator.
- the opening of the contact bridge produces the angular displacement of the partition, so that one of its ends approaches the small wall and the other moves away from the wall, in such a way that, when the handle is operated, the wall approaches the closer end of the partition, pressing against it and forcing it to shift in the opposite direction toward the initial reset position, in which the partition and the wall are parallel and in contact.
- the actuator is assisted by a spring, so that after the reset is effected and the handle is no longer acted upon, the actuator is forced to return to its initial idle position.
- the actuator is joined to the handle by a cable housed in a sleeve.
- the ends of the sleeve are attached to a support of the handle and to a support of the actuator.
- the end of the actuator has an elastic stop that limits the movement of the actuator during reset, so that it stops at the end of the sleeve through which the cable runs.
- the actuator has a stop that stops at the frame of the switch to define the initial idle position of the actuator.
- the handle also has an elastic stop that limits its movement when it is released after the reset is effected.
- an elastic stop that limits its movement when it is released after the reset is effected.
- Figure 1 shows a perspective view of one possible embodiment of the device of the invention.
- Figure 2 shows a partially sectioned plan view of the device represented in the previous figure. DESCRIPTION OF THE PREFERRED EMBODIMENT
- the device of the invention is applied to a switch that comprises a support
- support 1 has two pin-shaped extensions 3 and the central branch 5 of a T-shaped actuator 4 is positioned between these pin-shaped extensions. In the position at which the contact bridge is closed, pins 3 are located parallel to arms 6 of actuator 4.
- Actuator 4 can be displaced so that it is guided into frame 2 by means of tabs 8a and 8b.
- actuator 4 is assisted by a spring 7, whose front end is supported by washer 9 and whose back end stops at tab 8b of frame 2.
- actuator 4 is solidly joined to stop 10, and its back end is capped by terminal 11 which forms the connection to cable 12, whose opposite end is connected to handle 13.
- Cable 12 runs through sleeve 14, which allows the cable to move when handle 13 is operated.
- Sleeve 14 is mounted to frame 2 by means of terminal 15 which houses the end of sleeve 14 and is held by nut 16.
- Terminal 11 is protected by elastic stop 20 and handle 13 is protected by elastic stop 21.
