Problems solved by technology
[0008] - It is possible to keep the product in the connected position and the pulled position without locking, which will cause the danger of automatic separation of the switching device under the action of electric disconnection
[0009] In addition, it is inconvenient to identify the disable hole and the insertion lock, since their location is inaccessible in the lower part of the drawing frame

Embodiment Construction
[0045]In the following, all terms "high", "low", "right", "left", "front" and "rear" used in the specification, refer to figure 1 The pull frame shown.
[0046] Furthermore, the position of the switching device corresponds to the position of the carriage on which the switching device is fastened. Therefore, for a better understanding of the invention, the position of the carriage and not the position of the switching means will be described.
[0047] figure 1 It is an overall view of the drawing frame of the present invention. The pull frame has an engagement base 3 adapted to be fixed against a wall. On the right and left of the joint base 3 are disposed side plates 4 , which refer to two side members mounted on both sides of the joint base 3 and are fixed relative to the joint base 3 . The carriage 2 equipped with the switching device 1 cooperates with the side plate 4 by means of pins 8 which extend from the carriage 2 and slide in slots 17 arranged for this purpose on ...

The present invention relates to a draw-out frame for a circuit breaker (1), which is capable of being arranged so as to keep said circuit breaker (1) in a plugged-in position in a connection socket (3) or in an unplugged position from said socket (3). Said frame comprises two stationary flanges (4) capable of being connected to the socket (3), and a movable carriage (2) capable of supporting thecircuit breaker (1) and provided with guiding means engaging with the corresponding stationary flanges (4) in order to provide the movement of the circuit breaker (1) from one to the other of said plugged-in and unplugged positions. Each stationary flange (4) is fitted with an operating lever (5) provided with a handle (6) and pivoting about a stationary axis. Said lever (5) is arranged to engagewith said means for guiding the carriage (2), each lever (5) being provided with a locking device arranged to block said lever (5) in a position corresponding to one or the other of said plugged-in and unplugged positions of the circuit breaker (1). The unplugging frame comprises means for simultaneously articulating the two levers (5), characterized in that it comprises means for coupling the operation of the levers (5) with the operation of the locking device.
Description
technical field [0001] The invention relates to a drawer for a switching device, suitable for holding said switching device in a connected position on a joint base or in a drawn position of the joint base. Such pull frames usually have two fixed side panels, which are adapted to be connected to the joint base, and a sliding frame, which is suitable for carrying the switching device and is equipped with guides, which cooperate with the corresponding fixed side panels , to ensure that the switching device moves from one of the connected position and the pulled position to the other. Each fixed side plate is equipped with a joystick equipped with a handle and pivoted about the fixed axis, said joystick is intended to cooperate with said guide of the carriage, each joystick is equipped with a locking device, Locking means are used to lock the operating lever in a position corresponding to one or the other of said connecting position and pulling position of the switching device. ...
