Definitions
- the present invention relates to an autonomous mechanical key control device, the miniaturized key of which is completely integrated into the surface of a ring and which operates by simple external contact face to face with the sliders of its control unit.
- This key control device comprises two following elements:
- a key ring whose face is engraved with several parallel grooves. Each groove materializes, by its length, a code value. The function of this key ring is the possession of a code which activates the command.
- a control unit comprising a base and a movable plate.
- the plate is held in the rest position by an elastic mechanism. When pressed, the plate sinks into the base.
- the plate has on the surface a window through which there is a row of sliders arranged in the same pitch as the grooves of the key ring.
- the window has a protruding side slide and a lower stopper used to guide the movement of the key ring.
- Each cursor has a guide light cut in the direction of its movement, and, on its inner profile, a toothing and a notch.
- the interior of the plate comprises on the two lateral sides of the window an upright in which is fixed a guide bar. This bar guides the cursors in translation.
- the sliders are each held in the rest position by an elastic mechanism. The sliders can all move the same length, according to a defined number of positions. This length is limited by the upper edge and the lower edge of the window. The number of possible codes is equal to the number of these positions raised to the power of the number of sliders.
- the notch materializes the position of the cursor code; and all the notches have the same depth and the same width.
- the base includes a code sensor and a control sensor, both placed side by side and perpendicularly opposite the serrated profile of the sliders.
- the code sensor is used to detect the correct codes of all the sliders and is protected against possible overwriting following a heavy strike on the turntable. Indeed, the code sensor is mounted on a damper keeping it in its rest position. If the board is pressed
- the control sensor is mounted on a spring mechanism keeping it at rest in the control locking position. When this sensor is pressed, his foot moves towards the unlocking position of the control. The distance between these two positions is determined by the depth of the slider notch.
- the control activation mechanism consists in sliding the key ring in the protruding slide of the control unit until it comes into contact with the slide stopper and then pressing, still with the key ring, on the plate until activation of the command.
- This control activation mechanism results in the fact that by sliding the key ring up to the stop of the slide, each slide which is opposite it is dragged to its correct and unique position. .
- This position is determined by the length of the corresponding groove on the key ring. So, and only when all the sliders are each in this position (representing the correct code), the notches on the serrated profile of the sliders are aligned and together form a transverse groove which fits into the code sensor without pressing it in, as you press the plate. At the same time, these sliders push the control sensor towards its control activation position.
- the sliders can have different widths constituting additional coding.
- the code sensor can be fixed and without damper if protection against possible crushing is not essential for certain applications.
- Figure 1 shows the key ring and its control box.
- Figure 2 shows the face of this key ring.
- FIG. 3 represents a cursor and some cursor notches of different position.
- Figure 4 shows the plate seen from the front and without cursor.
- FIG. 5 represents the plate seen from behind with an example cursor.
- Figure 6 shows the collar
- Figure 7 shows the guide portion of the sliders.
- Figure 8 shows the base seen from the front.
- Figure 9 shows the base seen from behind.
- Figure 10 shows the code sensor and the control sensor in the idle state.
- FIG. 11 represents the code sensor and the control sensor when a cursor is pressed in its correct position.
- FIG. 12 represents the code sensor and the control sensor when a cursor is pressed in its wrong position.
- FIG. 13 represents the code sensor and the control sensor and the parts constituting their shock absorbers.
- the code for the key ring comprises eight digits from 00000000 (rest position of the eight sliders) to 99999999 (position of the sliders at the stop), ie 10 8 possible combinations.
- the dimension of the key ring is of the order of 8 ⁇ 10 mm plus the edge of approximately one millimeter, ie one millimeter per pitch of groove. The latter will be easily reduced for industrialization.
- the control box will have dimensions of the order of 30x30x20mm.
- the device according to the invention and an embodiment comprises:
- a key ring (1) whose face (2) is engraved with several parallel grooves (3).
- a control unit comprising a base (4) and a plate (6).
- the plate (6) is guided in translation in the base (4) and is stopped in one direction by the bottom of the base (4) and in the other by a flange (5).
- the plate (6) is held in the rest position (contact with the collar (5)) by four cylindrical springs with angular action (18). When pressed, the plate (6) sinks into the base (4).
- the plate (6) has on the surface a window (14) through which there is a row of sliders (9) arranged in the same pitch (10) as the grooves (3) of the key ring (1).
- the window (14) is provided with a projecting lateral slide (7) and a lower stop (8) serving to guide the movement of the key ring (1).
- Each cursor (9) has a guide light (11) cut in the direction of its movement, and, on its internal profile, a toothing (12) and a notch (13).
- the interior of the plate (6) comprises on two lateral sides of the window (14) an upright (15) in which is fixed a guide bar (16). This bar (16) guides the sliders (9) in translation.
- the sliders (9) are each held in the rest position by a cable (19) secured to a cylindrical traction spring (20) and returned by a set of pulleys (17).
- the sliders (9) can all move the same length, according to a defined number of positions.
- the number of possible codes is equal to the number of these positions raised to the power of the number of sliders.
- the notch (13) materializes the position of the cursor code; and all the notches have the same depth and the same width.
- the base (4) comprises a code sensor (21) and a control sensor (23), both placed side by side and perpendicularly opposite the serrated profile of the sliders.
- the code sensor (21) is mounted on a damper (22) keeping it in its rest position. If the plate (6) is pressed strongly while one of the sliders (9) is in the wrong position, this sensor (21) sinks towards the control locking position (its light (25) off the axis release (27).
- the control sensor (23) is mounted on a spring mechanism (24) keeping it at rest in the locked position of the control (where its light (26) is not in the release axis (27) ).
- this sensor (23) is depressed, its foot goes towards the position for unlocking the control (where its light (26) is in the axis for unlocking the control (27)).
- the distance between these two positions is equal to the depth of the notch (13) of the sliders.
- the command can only be activated if there is displacement of the control sensor (23) and immobility of the code sensor (21).
- the control activation mechanism consists of sliding the key ring (1) in the protruding slide (7) of the control unit until contact with the stopper (8) then pressing, still with the key ring ( 1), on the plate (6) until activation of the command. That is to say, by sliding the key ring (1) up to the stopper (8), all the sliders (9) are slid to their proper and unique position. This position is determined by the length of the corresponding groove (3) on the key ring (1). Thus and only when all the sliders (9) are each in this position, the notches (13) on the serrated profile of the sliders (9) are aligned and together form a transverse groove which is embedded in the code sensor (21 ) without pushing it in, as you press on the plate (6).
- the sliders (9) push the control sensor (23) towards its control activation position.
- at least one of the cursors is badly placed (its notch (13) not being opposite the code sensor (21)) and causes that, when pressed of the plate (6), the code sensor (21) is pushed in and blocks the activation of the command.
