Definitions
- the invention relates to the light keys, in particular the illuminated multi-message light keys for the facades of equipment, in particular aeronautics or automobiles.
- Message means any kind of pattern, type symbolic or alphanumeric, usually worn in front before keys or buttons, indicating the function of the button, and, if applicable, the status of the ordered action (s) by said key or said button.
- the light keys used for the equipment aeronautical operators must perform several functions despite their small size, which contributes to the complexity keys currently encountered. Indeed, these keys must simultaneously ensure electrical contact by pressure on a contactor installed on the facade, and a information by means of a luminous signage, making usually call for a transparent front end with a hides the form of the message, backlit by lighting inside.
- the light sources can be of the same color, or different colors.
- Known keys having an equipped base with an electrical contactor and at least two sources of light, and having a push button opposite the contactor and light sources, said projecting button the facade.
- This button is constituted by a body of button rigid injection, which body presents internally a housing for a pusher provided with a spring, forming the resilient biasing means of the button and actuating the contactor.
- This button is closed on its front face by a label (called a jack), with transparency the two messages to illuminate.
- a label called a jack
- Inside the body of button is partitioned in such a way that each light source illuminate one and only one message.
- the inside of the body button is usually painted white to promote diffusion of light.
- a seal reported sealing is arranged around the body of button to be squeezed between the button body and the facade.
- US-A-4,535,396 discloses a push button similar in design to that of the previous push button, but realized in a simpler way. It includes effect a cloisonné cage in which are threaded two translucent blocks, the cage being inserted into a body between a cylinder and a support of diodes, all forming a rigid assembly linked to a return spring. In this arrangement, the translucent block only provides an optical function.
- keys comprising a button came integrally with a support rim, to which he is connected by a flexible peripheral ligament forming the elastic return element.
- the electrical contact is obtained thanks to the presence of a central finger inside molding with the button and pressing a contactor electric carried by the facade.
- To obtain keys bright we mold this type of button in a material translucent, then we paint the outside in black. The face before is then engraved or equipped with a jack, for example by gluing. We get in a very simple way a touch light. But unfortunately, it is not possible with this kind of keys to get independent lighting several messages, due to the transparency of the material used, which would drive the different light sources indifferently to the different messages carried front side, which would lead to confusion in signaling.
- JP-A-11 73838 The state of the art is also illustrated by JP-A-11 73838.
- This document describes a button pusher comprising a unitary element of flexible design, comprising a support flange and a touch body hollow connected by a peripheral ligament, the body being compartmentalized by a central partition.
- the body is covered by a rigid rollover, the presence of which is actually made necessary by the lack of block translucent inside the key.
- JP-A-01 211195 which describes a key according to the preamble of claim 1.
- the invention aims to design a light touch multi-messages with independent lighting, not presenting not the aforementioned drawbacks and limitations. This is achieved with a key according to claim 1.
- a light touch equipping a facade of equipment including equipment aeronautics, including a support rim, and a hollow key body ending with a front face of maneuver covered with a mask engraved according to messages to illuminate, said key body being connected to said flange by means of a peripheral ligament, said body, said ligament and said rim being made so unitary in a flexible material.
- a block of translucent material divided into cobblestones by at least an opaque partition substantially perpendicular to the face frontal, is enshrined in the interior of the sideline to extend to the front end of maneuvering the touch.
- the translucent block of the aforementioned light button allows not only to drive the light, but also to rigidify the touch body which is of flexible design, which eliminates the need for a rigid rollover.
- each tile independently drives the light from one of the sources, each light path being separated from the other by the opaque partition.
- Each source can so illuminate a different message that is part of the mask common, each one facing one of the pavers.
- the support flange is shaped to present a peripheral excrescence acting protruding gasket on the side of the facade.
- the watertightness is ensured without it being necessary to use a reported seal.
- the tiles are joined at the front face.
- the opaque partition separates them, but the pavers are always secured by a thin ligament caught between the partition and the mask. Pavers are thus more easily manipulated during the manufacture of the touch, especially if you use more than two pavers. In addition, the aforementioned ligament strengthens the frontal face of the body touch.
- the pavers are disjoint. This gives a total optical separation two light paths, since the opaque partition can extend to the mask.
- the mask is a label carrying in transparency messages to be illuminated.
- an opaque coating covers the maneuvering face, revealing messages to illuminate on the maneuvering face.
- the finger is advantageously carried by the opaque partition.
- the pavers are stuck in the body of touch.
- the blocks are snapped in the touch body.
- the touch body with its or its partitions, and the associated support ledge have come overmolding on the pavers, being made of a material opaque.
- the invention also relates to a strip of keys lights according to claim 12, consisting of a plurality of juxtaposed keys having at least one of the characteristics aforementioned, the support flange of said keys forming a peripheral support rim of said bar.
- equipment 1 of the type calculator or aeronautical control box is equipped with a frontage 2 in which is provided at least one orifice 3 for projecting a body 4 parallelepiped shaped key, with a flange 5, a key 6 according to the invention.
- the flange 5 is sandwiched between the equipment 1 properly said and its facade, so that rim 5 is immobilized between these two elements.
- the body of key 4 is linked at the support rim 5 by a ligament or peripheral membrane flexible 7, acting as a spring to reposition the body of key 4 after its maneuver.
- the touch body 4, the ligament 7 and the support rim 5 are made of unitary manner in a flexible material.
- This support flange 5 has, in addition, protruding towards the front 2, a sealing gasket 8, intended to prevent that moisture seeps under the facade 2.
- the seal 8 is in this case came from matter with the rim 5, and therefore does not constitute a separate component as was the case with earlier keys.
- AT inside the touch body is enshrined a block 9 of translucent material, for example silicone, against a flange 10 inside the body of touch, said block 9 being separated into two blocks 11 and 12 by means of an opaque partition 13, separating the two pavers 11 and 12 over the entire dimension 4.
- the partition 13 thus separates the block 9 throughout the length of the touch body 4.
- These pavers 11 and 12 participate in the structural rigidity of the body of key 4, which is made of flexible material.
- these blocks 11,12 can be glued in the touch body 4.
- these pavers are overmolded 11,12 with an opaque material, for example silicone, to form touch it directly around the pavers.
- an opaque material for example silicone
- Pavers 11 and 12 each lead the light from two light sources 16 and 17 related to the equipment and lying behind the cobblestones 11 and 12. These light sources can for example LEDs, ordered for light according to a defined logic and implemented in equipment.
- the presence of the opaque partition 13 prevents a light source assigned to a tile illuminates the pavement adjacent. Each pavement thus leads the light of a only source.
- the two sources are of different colors, you get a two-tone touch.
- Pavers 11 and 12 extend to one face front maneuver 19, or front face, to drive the light towards the outside of the light key 6.
- This front face 19 is covered with a mask 18.
- these masks 18 let appear in transparency two patterns for each light touch bi-messages, some of which correspond to a message readable such as (ON, OFF, CALL, STOP, MECH), others representing a symbolic pattern (square, rectangle, or any other form), each one being at the foot of a pavement.
- Each pattern or message is therefore illuminated by a single source.
- This mask 18 may consist of a label glued on the front face 19.
- this mask covering the front face 19 of an opaque coating then removing the part of that matching coating the desired patterns or messages, for example by a laser engraving process.
- the messages can be secret, that is to say that the messages are not readable by day if they are not enlightened; alternatively, the messages can be rendered readable by day, for example by painting translucent.
- Partition 13 protrudes a finger 14 directed to the equipment, to operate an electrical contactor associated with the equipment 1.
- FIG. 3 presents a series of key bodies 52 grouped into a bar marked 50, comprising a common peripheral support rim 51, formed to from the support edges of the illuminated keys and juxtaposed. Peripheral seal (not visible in the figure) then ensures overall tightness for the entire bar thus formed.
- keys can be grouped according to any type geometric arrangement, and in particular in a table of keys.
- FIG. 3 distinguishes partition 13 separating the pavers 11 and 12 along the length of each body 52, and projecting from the support flange 51 a operating finger 14.
- the shape of the key is not limited to a parallelepiped, but can instead take any type of shape, polygonal, circular or other.
- partition (s) are not necessarily rectilinear.
