Description

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 according to the preamble of claim 1.

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.

Thanks to advances in the development of electronic components, the size and price of electronic components has dropped dramatically over the past 50 years, and the ever greater integration of transistor functions in microprocessors has dramatically increased the scope of possible functions, reducing the amount of electronics involved in manufacturing costs Remote unit has continued to fall, so that the current state of the art, the cost of the housing and the cost of energy supply are becoming an ever greater part of an electronic device that is already so large that only at this point significant cost savings can be achieved.

Furthermore, increased economy and improved ergonomics require an ongoing reduction in external dimensions, whereby a reduction of the material consumption is to be achieved.

In the current state of the art, the energy requirements of a radio remote control of increasing importance, since the cost of electrical energy storage - ie for batteries - due to increasing worldwide demand but limited capacity of the required raw materials continuously increase and the largest share of the total operating costs on the Lifetime can be.

Against this background, it is becoming increasingly interesting to be able to operate a radio remote control without a complex external supply of energy. Such a device presents the utility model DE 20 2004 005 837 , 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 Indian DE 20 2004 005 837 However, presented switch has the significant disadvantage that it is designed with the same visual and haptic appearance that has been customary for electrical switches of lighting fixtures in homes. This results in relatively very large and angular forms. According to his task, this switch builds on a large base plate which is to be screwed onto a mounting surface.

Because 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, however, 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 device of the generic type is the US 2007/182594 removable, showing a housing open to the outside, the interior of which is accessible to foreign bodies and therefore prone to failure and also cumbersome due to the complex structure in the production.

Against this background, the invention has the task of developing a radio remote control, which offers the highest possible protection against foreign bodies and is relatively lightweight and material-saving and easy to produce with simply designed forms.

As a solution, the invention teaches the features specified in the characterizing part of claim 1.

To attach the radio transmitter module is a cassette into which the radio transmitter module is inserted only and with the aid of which it is then attached to a housing part.

In particular, when the radio transmitter module consists of several parts, the cassette is advantageous because it can then also serve as a connection for the parts of the radio transmitter module.

The division of the radio transmitter module takes place in the two mechanically separate modules of an electric generator and a radio transmitter board. When the electric generator generates electrical energy upon movement of the actuating rod, which is removable on two contacts, on which two complementary, resilient contacts must be pressed by the radio transmitter board, the cassette serves both for the electric generator as also for the radio transmitter board as a holder and also as a clamp. 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.

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.

If the consumer has more than one function to be selected and activated with a single remote control, 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.

To activate the radio remote control, the two housing parts are manually pivoted toward each other, whereby the operating rod of the radio transmitter module is pivoted and thereby the leaf spring jumps 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. Meanwhile, 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.

If the radio transmitter module is programmed so that it only starts a counter on arrival of the first amount of energy, which is stopped upon arrival of the second energy pulse, the time duration between these two energy pulses can be detected by the radio transmitter module and translated into a certain information, which then the radio signal is forwarded to the receiver.

If the housing is also intended to protect against permanently applied moisture, then the invention proposes another embodiment of the housing in which only one housing part can consist of a cost-effective, rapidly embrittling material. In this case, 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 a higher protection class can be achieved, which can include a permanent protection against moisture.

The radio transmitter module is attached to the flexible housing closure and its actuating rod is pivotally connected to the housing pan. When pressure is applied to the flexible housing closure, 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 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.

• die hohe mechanische Stabilität trotz geringem Materialeinsatz und
• ein ausreichender Innenraum zur Aufnahme des Funksendemoduls und
• dessen Bewegbarkeit gegenüber einem weiteren Gehäuseteil zur Aufnahme der vom Nutzer manuell eingebrachten Energie und
• den Schutz des Funksendemoduls vor Fremdkörpern und Verschmutzung.

An essential feature of the invention is the trough-shaped design of a housing part, through which the three essential functions of the housing can be met, namely

• the high mechanical stability despite low material use and
• a sufficient interior space for receiving the radio transmitter module and
• its mobility relative to a further housing part for receiving the manually introduced by the user and energy
• the protection of the radio transmitter module against foreign bodies and contamination.

The large surface of the tub serves on your outside as pressure surface for the fingers of a human hand with the activation of the Radio remote control. As a second pressure surface for applying the required back pressure is used, the large area of the second housing part. For receiving the pressure forces during actuation of the radio remote control according to the invention, the housing must have a correspondingly high strength, which runs contrary to the task of saving material and the usability of over its lifetime in its strength decreasing material.

It is the merit of the invention, by the use of at least one trough-shaped housing part even with a very small material thickness of the large area of the tub to achieve sufficient stability in that the side walls of the tub are aligned for a large part approximately perpendicular to the large area and on this Way the entire housing is given a much higher stability than it would have a plate-shaped base of this material thickness alone.

Even if the material thickness of the side walls is as low as the material thickness of the large area, their contribution to the reinforcement of the large area is still much greater than with a tilted orientation. By this feature, the task of the invention for a high stability with low material usage is met.

The radio transmitter module can in the most general case be attached in any manner anywhere in the housing.

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. Well known and proven are coil springs or coil springs, which claim only a relatively small space, but are relatively expensive and short-lived.

An alternative to this are 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.

If the relatively large, elongated movement margin for a leaf spring has been taken into account in the design from the outset, there are no corresponding additional costs in the production compared with a construction with a helical spring.

Alternatively, 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 can be attached in any manner in the housing, such. B. with an adhesive bond as well as with a screw or a connector.

If the flexible housing closure z. B. 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.

Even in the versions with the highest degree of protection, a radio remote control according to the invention can emit various commands. For this purpose, 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.

Alternatively, this function of the spring is integrated in the housing closure. For this he exists z. B. of permanently elastic rubber, through which the pressure range of the housing closure after removing the externally acting pressure force on the pressure area automatically returns to its original position.

In the following, further details and features of the invention will be explained in more detail with reference to an example. However, this is not intended to limit the invention but only to explain. It shows in a schematic representation:

FIG. 1

Cut through a radio remote control with two rigid housing parts.

FIG. 2

Section through a radio remote control higher degree of protection with a rigid and an elastic housing part.

In FIG. 1 is a radio remote control across its pivot axis 23 diagrammatically cut. The pivot axis 23 - right in FIG. 1 - thus points to the viewer. The section runs through all parallel to the pivot axis 23 aligned walls. The perpendicular to the pivot axis 23 oriented walls W can be seen in the plan and not hit by the cut. Very fast to recognize in FIG. 1 the upper housing part 21 with obliquely hatched cut surfaces and the lower housing part 22 with also obliquely hatched cut surfaces.

It is obvious that the upper housing part 21 together with the lower housing part 22 completely encloses the inner space with the radio transmitter module 1, namely parallel to the pivot axis 23 with the surfaces of the housing 2, which are aligned perpendicular to the viewer. The interior of the housing 2 is completed by the parallel to the plane, ie perpendicular to the pivot axis 23, extending walls W.

In FIG. 1 is very good to see that the wall W 21 of the housing top 21 is much larger than the wall W 22 of the housing base and they overlap for the most part. In FIG. 1 the lower edge of the wall W 21 is shown in dashed lines, since it is covered by the wall W 22 of the housing base. The wall W 21 of the upper housing part forms, together with the curved areas of the housing, the side walls of the trough-like basic structure of the upper housing part 21. In the region of the - downwardly facing - opening of the upper housing part 21, the upper housing part 21 comprises the Housing base 22 so at the aligned perpendicular to the pivot axis edges and touches it at the other edges. Very good to see in FIG. 1 in that the wall W 22 of the lower housing part overlaps with the wall W 21 of the upper housing part 21.

In 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. In 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. In FIG. 1 However, it is understandable that a gap thanks to the relatively large surface of the overlap is a pretty good seal against penetrating foreign bodies.

For the two - running perpendicular to the plane - joints between the upper housing part 21 and the lower housing part 22 is in FIG. 1 clear that their seal is to be solved differently than in the area of the walls, since in this case the elements to be sealed against each other do not have to move past each other, but only toward each other. Thus, there are defined bearing surfaces, with which the two housing parts 21 and 22 abut each other in this area of their outer surfaces. In these areas, they are pressed together by the force of the spring 3, so that with a low tolerance in the compatibility of the support surfaces in these areas a good seal is ensured.

In FIG. 1 is understandable that in this embodiment during the activation of the radio transmitter module - ie during the Pivoting of the two housing parts 21 and 22 against each other - in the perpendicular to the plane extending areas of the housing - ie on the right and on the left - move the retired touching surfaces away from each other, so here each opens an opening, but is immediately closed again after the deactivation of the radio remote control by the spring, so that the protective effect of the housing is reached again.
In FIG. 1 also the formation of the pivot bearing for connecting the two housing parts 21, 22 clearly: In FIG. 1 is marked with a cross, the pivot axis 23 about which the wall W22 and the lower housing part 22 relative to the upper housing part 21 are pivoted. This pivot axis 23 is therefore the center of the pivot bearing. On the right side of the wall W 22 of the lower housing part 22, the bore 25 can be seen, in which the pin 24 protrudes and the cross-sectional area of the bore 25 completely fills. Since the pin 24 assigns to the viewer is in FIG. 1 only to see his faces. Also in FIG. 1 is not visible that the pin 24 is fixedly connected to the upper housing part 21.

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 border is encompassed on three sides by the upper housing part 21, in the plane of the drawing and in a second, parallel thereto, in FIG FIG. 1 but not shown each level by a respective wall 21 and on the left side by a pocket 26. Only on the right side of the housing upper part 21 is brought up to the housing base 22 and is inactive remote control on it, but does not overlap it.

In FIG. 1 As a possible variant for the installation of the radio transmitter module 1, a cassette 4 is shown. 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.

From the electric generator 12, 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. In 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.

In FIG. 1 is very nice to understand that the cassette 4 is dimensioned so that touch after inserting the electric generator 12 and the subsequent placement of the radio transmitter board 13 to the electric generator 12, the electrical contacts 14 of both components. By the spring in each contact 14, the radio transmitter board 13 is pushed slightly upwards and is slightly beyond the edge of the cassette 4 addition. When locking the cassette 4 in the corresponding retaining lugs on the upper housing part 21, the inner surface of the upper housing part 21 pushes the radio transmitter board 13 to the electrical contacts 14, so that even without soldering, screws or other connection a permanent and stable electrical contact is ensured.

In FIG. 1 is shown as an embodiment of the spring 3, a leaf spring, which is shaped in this embodiment, that it is centered between the left and right side wall of the housing base 22 and thereby even with only inaccurate insertion into the trough of the housing base 22 in the correct position to be led. In this position you will be in the left half of the FIG. 1 visible, movable part pressed against the lower edge of the cassette 4 and thereby spreads the two housing parts 21, 22 away from each other.

At the current state of the art, the housings for electronic devices are cast almost exclusively of plastic. By casting, the current production costs are relatively low and the pace of production is pleasingly high. The disadvantage is that it requires a relatively complex form. FIG. 1 shows that according to the principle of the invention, the requirements for this form are relatively very low.

The experience in dealing with plastic also teaches that after a short time, the material begins to become brittle and then still can be loaded on pressure, but no longer on train and in particular on no longer permanently and irreversibly moldable, but then on regularly moving points soon show "fatigue fractures" and the entire part then fails. Of these, in particular catch connections and other sections are concerned, which must be moved again and again.

It is another special feature of the invention that 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.

In FIG. 1 It can be seen that this principle of designing a housing consisting of two nested trays also offers the advantage of being able to be adapted to a material that is as poorly resilient as an aged plastic: In the right part of FIG FIG. 1 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 down 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.

In FIG. 1 is an embodiment of the spring 3 between the housing parts 21, 22 to be seen as a leaf spring 3. This leaf spring 3 generates in the left area of the cassette 4 a pressure on the cassette 4 and on the inside of the housing base 22. By forming a leaf spring 3 ensures that the support surface is relatively large, so that a brittle expectant material not on a single Point is overloaded, since the force of the leaf spring evenly distributed over a larger area.

In FIG. 1 is also understandable that despite the small number of parts, the installation of the radio remote control invention comparatively still is easy. At the beginning is in the upper housing part 21 in the pocket 26 at the in FIG. 1 left side of the left edge of a housing lower part 22 inserted and indeed to the stop. Meanwhile, the right side of the lower housing part 22 with the bore 25 is still spread quite far from the upper housing part 21. By this fairly large opening between the two housing parts 21,22, the spring 3 is first inserted and inserted into the lower housing part 22.

In the next step, a cassette 4 is placed on it, in which an electric generator 12 and thereon a radio transmitter board 13 are located. In the following step, through the large opening between the two housing parts 21 and 22 through the cassette 4 with their locking lugs on the corresponding counterparts on the inside of the upper housing part 21 is engaged, so that the upper housing part 21 presses on the radio transmitter board 13, which in turn is supported with the electrical contacts 14 on the electric generator 12 and is ready via the contacts 14 for receiving electrical energy.

In the next step of the assembly, the lower housing part 22 is again moved to the right to the extent that the actuating rod 11 of the radio transmitter module engages in the complementary recess in the side wall of the housing lower part 22.

Meanwhile, the lower housing part 22 is still "obliquely" with respect to the upper housing part 21. In the next step of assembly, the lower housing part 22 is pivoted at its right edge into the upper housing part 21, wherein it should be noted that the pin 24 on the wall W 22 of Housing base 22 must pass by must. For this purpose, it is necessary that the side walls W 21 of the housing upper part 21 can be pressed outwards and the walls W 22 of the housing lower part 22 are pressed inwards. Then the pin 24 slides with its end face along the wall W 22 of the housing base along and "locks" in the bore 25, once it has reached.

In FIG. 2 a longitudinal section of a radio remote control according to the invention is shown in an embodiment of the housing in which the lower housing part - the housing trough 27 - is permanently closed at the top by an upper housing part - the permanently flexible housing closure 28. By hatching the cross-section of the housing trough 27 is symbolized that it consists of a permanently rigid material. For the housing closure 28 is shown by a puncture of its cutting surface that it is permanently flexible.

In the FIG. 2 shown variant shows as in FIG. 1 a cassette 4 for receiving the radio transmitter module. In contrast to FIG. 1 However, the cassette is not secured by locking lugs on the upper part of the housing, but on a circumferential bead, which forms an undercut, into which a complementary collar at the upper edge of the cassette 4 inserts. This ensures a secure fit of the cassette 4 despite a permanently flexible material for the housing closure 28.

As with the version in FIG. 1 protrudes from the electric generator 12, an actuating rod 11 which engages in a recess in a transverse wall in the housing pan 27.

In FIG. 2 the sequence of the transmission of a radio signal is well understood: By pressure on the surface of the housing closure 28, the attached cassette 4 together with the radio transmitter module is moved closer to the housing pan 27 zoom. As a result, 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: In the housing closure 28, a probe insert 5 is embedded. When a force acts on the probe insert 5 from the outside, it exerts a pressure on 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.

In FIG. 2 It is understandable that 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.
