ES259633U - Pulsation device (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Pulsation device, especially suitable for complementing an electrical switch or switch, the visible part of which is in the keypads of elevators and other electrical maneuver assemblies, characterized in that the upper edge of the electrical appliance box, rectangular in shape, presents two forked extensions extending from opposite corners in parallel and in opposite directions and having in their upper plane a recessed area in which a protruding area of a corresponding forked extension corresponding to a frame that closes the mouth of said box copying its parts is adapted. Peripheral shapes and which, with this pair of opposite couplings, is correctly centered, such overlapping of fork-shaped extensions being used to fix the device by screws whose heads are housed in two recesses of the extensions of the frame in whose central zone there is a square window bordered by a pest external peripheral year, through which the counter top of the pulsation key appears which is constituted by a metallic plate which is fixed by any appropriate means in the flat bottom of a recess existing in the surface of an upper projection, of perimeter square, of a hollow support whose peripheral skirt copies the internal shapes of the box of the apparatus, within which it can perform sliding movements that are resiliently recovered by the maneuvering means of the electrical device and guided simultaneously by the external forms of said upper projection, which fit gliders inside the frame window.2. Pulsation device, according to the preceding claim, characterized in that, while the frame and the metallic plate of the key are opaque, the hollow support of said plate is made of transparent material and therefore the small rim surrounding the recess of the the upper protrusion of the support, on the bottom of which the plate is fixed, determines, between said plate and the flange of the window of the frame, the existence of a groove of constant width that, during the operating moments of the apparatus, allows the light to pass through that produces an inner light bulb so that the repeated metal plate is surrounded by a light frame that allows its location. 3. Pulsation device, according to the preceding claims, characterized in that the falling skirt of the sliding hollow support engages on centering means that has the upper part of a sliding inner frame, with descending lateral fins that limit the displacements of the sliding assembly by contact with the bottom of the box, which march sliding serves as a link between the elements that make up the pulsation device and the maneuvering organs of the electrical device. 4. Pulsation device. (Machine-translation by Google Translate, not legally binding)
