Definitions

  • the invention relates to a radio remote condition consisting of a radio transmitter module protruding from a confirmation rod, through the mechanical movement of which electrical energy can be generated, which triggers a radio signal and a multi-part housing that receives a radio transmitter module and of which a first housing upper part relative to a second Housing part is movable and the relative movement activates the actuating rod.
  • Radio remote controls have been known for decades and proven remote controls, z. As for the opening of garage doors from a vehicle or for the activation of lighting fixtures or other electrical equipment to which the user does not want to go directly or go.
  • This radio remote control includes a radio transmitter module that includes an electric generator that generates electrical energy by movement of an actuating rod that is passed to a radio transmitter electronics that is programmed to emit a radio signal upon receipt of an energy pulse. This radio signal is received by a receiver at the consumer and converted into a command to operate this consumer.
  • a major advantage of this wireless remote control is that it does not require batteries or accumulators, but that converts the mechanical energy that the user applies when pressing the actuator button into electrical energy, with the help of the radio transmitter module is activated. This avoids not only the costs for the constant renewal of batteries or the expensive acquisition of accumulators and their constant charging, but also the necessary installation space and its coverage in the device can be saved.
  • the switch incorporates a radio transmitter module that includes an electric generator, it does not require power via a cable and would therefore, in principle, be usable as a mobile radio remote control.
  • the disadvantage here is its in relation to the built-in radio transmitter module considerable size and the predetermined by the design of the housing, very low protection against foreign objects entering from the outside. Also disadvantageous are the relatively high costs due to the complicated shape and the high number of parts of the housing.
  • the invention has taken on the task of developing a housing for radio transmission modules that offers the highest possible protection against foreign bodies and is relatively lightweight, but still as stable and compact and material-saving and easy way with simply designed forms produce and with very quickly embrittled and therefore reduced in their strength materials also at the end of the desired Duration of use still provides sufficient stability and functionality.
  • a first housing top is trough-shaped and has side walls which are at least partially aligned approximately perpendicular to the large surface of the housing part and in the region of its opening a complementary shaped area of a second housing part touches or encloses and the two large areas of the two Housing parts are spread apart by a spring.
  • the large surface of the tub serves on your outside as a pressure surface for the fingers of a human hand when activating the radio remote control.
  • a second pressure surface for applying the required back pressure is used, the large area of the second housing part.
  • the housing For receiving the pressure forces when operating the radio remote control according to the invention, the housing must have a correspondingly high strength, which is the task of material savings and the usability of his Life contrary in its strength decreasing material runs counter.
  • the radio transmitter module can in the most general case be attached in any manner anywhere in the housing.
  • the inside of the large area of the tub serves as a mounting surface for mounting the radio transmitter module.
  • the pivot bearing From this base from approximately perpendicular to extending side walls of the tub take on the pivot bearing, in which the lower housing part is pivotally mounted.
  • the transition between the base and the side walls can, for. B. continuously done by a hollow cylinder segment is inserted between the two levels, so that the production is simplified.
  • the side walls can only fulfill the protective function for the radio transmitter module in cooperation with the housing lower part, which almost completely fills the region of the opening of the housing upper part.
  • this base must not only be shaped like a flat lid, but can also be trough-shaped for an enlargement of the interior.
  • the outstanding feature of the housing base is its complementary to the housing top trained area. This leaves only a small gap between the lower part of the housing and the upper part of the housing so that foreign bodies, if any, can only penetrate if they pass through the gap between the two housing parts.
  • both housing parts are mutually pivotable, it follows that the two housing parts in the simplest case along a single line must be complementary to each other and in the most complex expansion stage in all angles of the possible pivoting. Then the area with a complementary shape extends at walls, which are aligned perpendicular to the pivot axis, on a circular sector-shaped surface, wherein the angle of the circular sector corresponds to the maximum pivoting angle of the two housing parts against each other.
  • the protective effect depends on the forms of formation of the gap between the two housing parts.
  • the gap between the two housing parts also retains its small size during the activation of the radio remote control - that is, during the movement of the two housing parts relative to one another.
  • the upper housing part is designed in the region of its opening as a hollow cylinder segment, specifically for all edges which do not run perpendicular to the pivot axis.
  • the complementary portion of the housing base then has the shape of a cylinder segment that is complementarily shaped to the hollow cylinder segment of the housing top, leaving a gap between the two parts.
  • this gap is as small as the requirement for mobility of the two parts against one another only permits. Since the protective effect is better, the smaller the gap, the desire for the smallest possible gap width occurs. However, the permissible lower limit is given by possibly different thermal expansions of the two housing parts as well as by deformations in the principle of pressing on both housing parts to activate the radio remote control.
  • the lower housing part closes the opening of the trough-shaped housing upper part only in the deactivated state, ie, therefore, when the spring between the two housing parts expands to their maximum possible length in the installed state Has.
  • the areas of the side walls of both housing parts which are formed perpendicular to the pivot axis also overlap in the simplest embodiment, since they serve to receive the pivot bearing for pivoting the two housing parts relative to one another.
  • the invention As mentioned, aligned perpendicular to the pivot axis walls to the two bearings, which allow pivoting of the two housing parts against each other.
  • a pivot bearing a separate component can be used.
  • the invention preferred a simple construction, which consists of a pin which is integrally formed on a wall and engages in a bore in the opposite wall. When pivoting the pin thus serves as a sliding bearing, which slides on the inner edges of the bore.
  • the two pins are formed on the upper housing part, which encloses the lower housing part, so that the two pins point inwards and towards each other. Each pin then engages in a hole in the walls of the housing base.
  • the advantage of this variant is that the pins are not visible to the outside.
  • the pins are arranged on the walls of the housing lower part and have away from each other, ie to the outside. Then the complementary holes must be introduced in the upper housing part. If this has a fairly small wall thickness, which is preferable in the interest of cost reduction, then the two holes are visible to the outside. Although they are filled by the moving therein pin, but form a joint, can penetrate into the impurities.
  • this hole can therefore be designed as a "blind hole", so that the pin is not visible from the outside. It is clear that, however, sufficient wall thickness must be available in the upper part of the housing.
  • the invention prefers to choose the diameter of the pin as large as possible, and indeed so large that even at a reduced strength of the material -. As an aged plastic at the end of its planned service life - the connection between the pin and wall is still strong.
  • the invention proposes to make the pin as a hollow cylinder.
  • the approximately uniform wall thickness across the entire housing part minimizes the risk of uneven shrinkage on cooling or hardening.
  • the connection between the pin and the hole should still fail - e.g. by breakage of the pin - proposes the invention as a further embodiment that then a sliding bearing of the two housing parts can take over each other the function of the pivot bearing.
  • the two side walls of the housing lower part, in which the bore is introduced are each formed at its upper edge as a circular arc segment, wherein the center of this arc segment is the center of the bore.
  • this circular arc segment has a small distance to the upper housing part, then the upper housing part can serve as a counterpart of a sliding bearing.
  • it must be formed in this area as a hollow cylinder segment, which is complementary to the Circular arc segment is formed on the upper edge of the housing lower part. Then it can serve as a plain bearing in a fracture of the pin, which takes over the function of the pivot bearing in the pivoting of the two housing parts against each other.
  • the invention provides that the housing upper part has at its opposite end of the pivot axis a pocket into which projects the lower housing part.
  • This bag can also be seen from the opening of the upper housing part as an undercut. If the lower housing part protrudes into this pocket-like undercut, so its lower surface serves as a stop which limits the pivot angle of the two housing parts against each other.
  • the lower housing part For mounting, the lower housing part must be pushed transversely to its pivot axis with an edge in the pocket, while the opposite edge is still far away from the upper housing part. In this mounting state, the radio transmitter module and its attachment can be introduced. Only in the next step, the other end of the housing base is brought together with the upper housing part by z. B. its two pins are engaged in the complementary holes of the upper housing part. With these few steps, the housing is assembled without a special tool.
  • An inventive housing has in each case a spring which spreads the two housing parts from each other.
  • This spring can z. B. be performed as a steel spring.
  • leaf springs which are easier to manufacture and therefore less expensive. Another advantage is that their bearing surface is significantly larger than the annular bearing surface of coil springs so that they exert only a relatively much smaller specific pressure on the bearing surface. Therefore, the support for a leaf spring made of much thinner and / or more brittle material than a coil spring.
  • springs made of plastic elements such as a silicone pad or a foam pad can be used. Or rubber elements serve as springs. These springs also spread apart the two housing parts.
  • the radio transmitter module may be mounted in the housing in any manner, e.g. with an adhesive bond as well as with a screw or a snap connection or a connector.
  • the invention proposes, as an interesting variant for attaching the radio transmitter module, a cassette into which the radio transmitter module is only inserted and with the aid of which it is then fastened to a housing part. If the cassette is connected to the housing part by locking lugs and complementary recesses, it can be mounted very quickly and without further tools, which is as advantageous for manual assembly as in assembly by robots. The locking connection saves the use of additional fasteners and the necessary tools.
  • the cassette is advantageous because it can then also serve as a connection for the parts of the radio transmitter module.
  • the radio transmitter module is divided into the two mechanically separate components of an electric generator and a radio transmitter board.
  • the electric generator generates electrical energy upon movement of the actuating rod, which is removable at two contacts, on which two complementary, resilient contacts must be pressed from the radio transmitter board
  • the cartridge serves both for the electric generator and for the radio transmitter board as a holder and also as a parenthesis. Namely, not only the two components are connected to the housing part during installation of the cassette in a housing part, but also pressed against each other, whereby on the resilient contacts an electrical connection between the electric generator and radio transmitter board is made, so that the electrical energy from the electric generator to the radio transmitter board can flow.
  • the radio transmitter board When a sufficient operating voltage is applied, the radio transmitter board automatically generates a radio signal, that is to say an electromagnetic wave, which is radiated via an antenna. This radio signal is picked up by a matching receiver and converted into a command for the consumer connected to it. The energy supply of the receiver is the same as for the consumer to be controlled by him.
  • this selection must be transmitted by transmitting the radio signal from the radio remote control.
  • One way to encode this feature is to set the radio remote control to operate. If z. B. the actuating rod of the electric generator moves a resting flat leaf spring, which is clamped between two joints so that it curves, then it can change from one curvature in the other direction curvature, so it is bistable.
  • the two housing parts are manually pivoted toward each other, whereby the operating rod of the radio transmitter module is pivoted, thereby skipping the leaf spring from one stable state to the other stable state. Through this skipping, it generates a certain amount of electrical energy in an electric generator in the radio transmitter module.
  • the radio remote control is held by the user in the "active" position, the two housing parts are permanently swung towards each other, but do not move against each other, so that no radio signal is emitted. Only when the user no longer puts the two housing parts under pressure, they are spread apart again by the spring, so that the actuating rod of the radio transmitter module is moved a second time and thereby emits a second amount of electrical energy.
  • the radio transmitter module is programmed to start only a counter on arrival of the first amount of energy, which is stopped on the arrival of the second energy pulse, the time between these two energy pulses from the radio transmitter module be detected and translated into a specific information, which is then forwarded via the radio signal to the receiver.
  • Another way to enter additional information is one or more keys built into the top of the housing.
  • the invention proposes to actuate these keys in the same direction as the radio transmitter module, so that the key is first activated by pressing and subsequently also the radio transmitter module is actuated upon continuation of this pressure in the same direction.
  • the user thus activates the button and then also pivots the two housing parts towards each other, whereby these two temporally separate steps appear to him like a single operating procedure.
  • the user can thus activate the radio remote control either without pressing the button or by pressing the button, as a result of which the radio remote control can send out two different information.
  • this key consists of a rubber body, on the underside of which a layer of conductive silicone is applied. This conductive layer is pressed on depressing the button on the top board of the radio transmitter module. There it encounters two contacts which are interconnected by the conductive silicone layer, which interprets the radio transmitter board as the activation of a particular function.
  • these contacts consist of two comb-like intermeshing tracks. Thanks to their large surface, even at relatively low pressure, a conductive connection is created.
  • each additional key can trigger an additional function.
  • the user can thus z. B. at a garage door opener, whether he opens his garage door a little further or closes a little more by the activation of the radio remote control.
  • the housing according to the invention provides very good protection against dust and spray, because the housing walls move past each other at a very small distance and even touch to a part. Despite this good protection, the housing is light and sturdy and can even be made from a relatively inexpensive plastic material that will become brittle after a relatively short time.
  • the invention proposes another embodiment of the housing in which only one housing part can consist of a cost-effective, rapidly embrittling material.
  • the first housing part is a rigid and inflexible housing tub, whose opening is closed by the second housing part, the permanently flexible housing closure.
  • On the outer surface of a pressure area is marked and by an externally acting on this pressure range force the actuating rod is moved relative to the electric generator, so that it emits electrical energy.
  • the housing closure must therefore be permanently flexible, since it must deform with each activation of the radio remote control. It is known that such a material is more expensive than a brittle material. The advantage, however, is that with it a higher protection class can be achieved is that can include a permanent protection against moisture.
  • the invention proposes two variants.
  • the radio transmitter module is mounted in the housing pan and the actuator rod is extended into the immediate vicinity of the pressure area of the housing closure.
  • Such an extension can either be formed directly on the projecting out of the radio transmitter module operating rod.
  • the push rod serves as an extension of a push rod, which is pivotally connected to the actuating rod.
  • the other end of the push rod can also be hingedly connected to the flexible housing closure.
  • the push rod carries at its end a small pressure plate on which the inside of the flexible housing closure is pressed.
  • the radio transmitter module is attached to the flexible housing closure and its actuating rod is pivotally connected to the housing pan.
  • the radio transmitter module moves relative to the housing pan to which the free end of the actuator rod is connected so that the electric generator can generate a flow of current.
  • the flexible housing closure for example, consists of a silicone rubber, so it can be formed on a circumferential collar, behind which engages a complementary collar on the upper edge of the cassette.
  • a radio remote control can emit various commands.
  • the invention proposes that at least one probe insert is embedded in the flexible housing closure. By pressing this button insert a switching element on the radio transmitter board is activated and moved by continued pressure on the probe insert the radio transmitter module relative to the housing pan. Because the actuator rod of the radio transmitter module is hingedly connected to the housing pan, it moves relative to the radio transmitter module, thus activating the electrogenerator.
  • the housing closure can move a spring back to its original position, which is arranged as a compression spring between the two housing parts and the parts spread apart after the elimination of the external pressure from the inside.
  • this function of the spring is integrated in the housing closure.
  • the housing closure consists e.g. made of permanently elastic rubber, through which the pressure region of the housing closure automatically returns to its starting position after the removal of the externally acting pressure force on the pressure area.

  • FIG. 1 is represented by a double arrow on the left side, as the upper housing part 21 is pivoted relative to the lower housing part 22.
  • FIG. 1 is well understood, as doing the wall W 22 of the housing base 22 slides on the wall W 21 of the housing top 21 along.
  • the fact that a very small gap between these two walls is required for good protection against penetrating foreign bodies is in FIG. 1 not representable, since the two walls are parallel to the plane of the drawing.

  • FIG. 1 In the embodiment according to FIG. 1 Not only is the upper housing part 21 trough-shaped, but also the lower housing part 22: In FIG. 1 On both sides of the housing base 22, the diagrammatically cut side walls are visible, which are curved and are aligned near the edge approximately perpendicular to the base. These side walls propagate in the plane of the wall in the wall W 22 and thus form an around the large base of the housing base 22 peripheral edge, which also gives the lower housing part in the form of a trough.

This cassette 4 is also shaped like a trough and receives in its lowest level the electric generator 12 of the radio transmitter module 1. In the in FIG. 1 In the embodiment shown, the electric generator 12 is provided with two small feet, which engage in complementary recesses of the cassette 4, so that the electric generator 12 can not move within the cassette.
  • the actuating rod 11 projects out, which is guided through an opening in the side wall of the cassette 4 and engages in a recess of the housing lower part 22.
  • FIG. 1 is very nice to understand that by a relative movement of the lower housing part 22 relative to the cassette 4, the actuating rod 11 is moved. As already mentioned, this causes the bistable spring connected to the actuating rod 11 in the electric generator to jump into the other of its two possible positions, thereby moving a permanent magnet past a coil in which electrical energy is thereby generated. This is forwarded via the two contacts 14 on the top of the electric generator 12 to two resilient contacts 14 on the radio transmitter board 13.

  • the snap-in connections and the necessary elasticity of the material of the housing parts only need to be taken during the first assembly, but then no longer required for proper operation of the radio remote control. Therefore, the housing can still be used even if the embrittlement of the material has already severely limited the elasticity of the material, but the material is at least still good under pressure on pressure.
  • FIG. 1 is visible that the inventive principle of designing a housing of two nested trays also offers the advantage of being able to be adapted to a poorly resilient material such as an aged plastic can:
  • the eye-like formation of the bore 25 in the wall W 22 of the housing base 22 is visible.
  • Its upper edge can serve in an emergency operation as a pivot bearing according to the following principle: If the wall W22 above the bore is so far enlarged that it reaches up to the inner surface of the housing upper part 21 zoom and if the top of this wall area arcuate segment-shaped and thus complementary to a hollow cylindrical area is formed in the inner surface of the upper housing part 21 and when one of the two pins 24 is broken off, so when pressing the two housing parts 21,22 against each other, the circular edge of the wall W 21 serves as a sliding bearing. In this case, the other remaining pin 24 prevents the lower housing part from being detached from the upper housing part 21 by its own weight.

This ensures a secure fit of the cassette 4 despite a permanently flexible material for the housing closure 28.
  • an actuating rod 11 which engages in a recess in a transverse wall in the housing pan 27.
  • FIG. 2 the sequence of the transmission of a radio signal is well understood:
  • the attached cassette 4 together with the radio transmitter module is moved closer to the housing pan 27 zoom.
  • the actuating rod 11 moves relative to the electric generator 12, whereupon a current pulse is generated, which - as in FIG. 1 - Triggers the transmission of a radio signal from the radio transmitter board 13.
  • the sectional view of the FIG. 2 shows how various information can be selected for this radio signal:
  • a probe insert 5 is embedded.
  • the switching element 6 which is evaluated by the radio transmitter board 13, whereupon the switching element 6 switches and thus emits another radio signal from the radio transmitter board becomes.
  • This signal activates in the radio receiver the desired of at least two or more desired commands.
  • a housing closure made of a permanently elastic material such as rubber can also act as a spring, which automatically pulls back "smooth" after the elimination of the external pressure force.
  • the drawn in the lower part of the housing pan 27 leaf spring 3 acts alternatively or in addition to an elastic housing closure 28 and presses the cassette 4 with the radio transmission module 1 again away from the housing pan 1.
