Description

The invention relates to a remote control device for entrance gates, front doors, garage doors and the like, with a box-shaped housing, an electronic circuit arrangement housed in the housing and at least one push button assigned to it, which is accessible from outside the housing through an opening formed in the housing.

In order to ensure long-term, reliable functioning of such a remote control device, it is essential to reliably protect the electronic circuitry from environmental influences, in particular from the ingress of dust and moisture as well as from impact and shock loads.

In some known remote control devices, this requirement is met by providing the housing with a thin coating of a transparent material, at least in the area of the access opening to the push button. The disadvantages of such a remote control device are the sensitivity of the coating to damage, increased production costs and the risk that the coating does not adhere completely to the housing, so that moisture can penetrate into the remote control device.

As an alternative to covering the housing with a cover, the use of touch switches on such remote control devices has been suggested, which

However, production costs increase unacceptably. 30

One aim of the invention is to provide a remote control device of the type mentioned at the outset, in which the discussed above disadvantages and deficiencies of known devices are avoided.

In a remote control device of the type mentioned at the outset, this aim is achieved according to the invention in that it has at least one actuating button made of an elastically flexible material, which in a locking

2 intervention into which at least one opening is inserted.

The remote control device according to the invention preferably has a recessed seat formed around the opening in the housing for receiving the said actuating button.

An embodiment of the invention is explained below with reference to the drawing. They show:

Fig. 1 is an oblique view of a remote control device in an embodiment of the invention,

Fig. 2 is a partial section along the line II-II

side view of the remote control device shown in Fig. 1 and

The remote control device 1 has a housing 2 consisting of two

veal shells 3, 4 which are placed one above the other and which are connected to one another in a locking engagement and are each formed from a plastic of sufficient rigidity.

The housing 2 contains a known electronic

% Circuit arrangement 5, which is mounted on an intermediate floor 6 in

'' Housing 2 is arranged. The electronic circuit

. arrangement 5 includes two closely arranged

P Push buttons 7 for activating the circuit arrangement

&ggr; _a0 and a light source 8, in particular a light-emitting diode,

⁽ ·· which is connected to the push buttons 7 and when pressed

_; activation of one of them lights up.

■; Opposite the push buttons 7 in the upper half shell

of the housing Z, two circular openings 9 are formed, &igr; 35 which are each surrounded on the outside of the housing ^ by a 't countersunk seat 10 of substantially square shape with rounded edges.

Preferably, each of the seats 10 formed in the upper half-shell 3 has a raised edge 11.

Opposite the light source 8, the upper half-shell 3 has an opening surrounded by a circular edge 12a. On the outside of the housing 2, the opening 12 is surrounded by a recessed, circular seat 12b, which in turn is surrounded by a raised edge 19.

In Fig. 2 one can also see a lens 13 made of an elastically deformable material, preferably a tri-polymer known under the trade name ELVA-S.

The lens 13 has a cylindrical first part 13a, whose diameter corresponds essentially to that of the countersunk seat 12b, and a second part 13b coaxial with the first part, whose diameter is slightly larger than that of the opening 12. A step 13c is formed between the two parts 13a and 13b of the lens 13.

The lens 13 is inserted into the opening 12 so that it rests with its step 13c on the recessed seat 12b and

that the second part 13b is held in the opening 12 in a press fit. This creates a secure seal between the edge 12a of the opening 12' and the first part 13a of the lens 13 compressed by the raised edge 19.

Each opening 9 of the remote control device 1 is assigned an operating button 14 made of an elastically flexible material, for example a rubber-like material known under the trade name DESMOPAN.

Each actuating button 14 has a curved upper part 15 which has a substantially square shape with rounded corners and which faces the respective push button 7 with its concave side. In the middle of the concave side of the upper part 15 there is a projection 16 facing the push button 7.

An annular lower part 17 formed in one piece with the upper part 15 of the respective actuating button 14 has a groove 18 on the outer circumference, which

annular edge 9a of the respective opening 9 can be brought into locking engagement.

The locking engagement of the groove 18 of the lower part 17 with the rim 9a of the opening 1 ensures a secure seal, while the upper part 15 of the actuating button is held in place in a form-fitting manner on the seat 10.

To actuate one of the push buttons for opening or closing a gate or the like via the electronic circuit arrangement 5, pressure is exerted on the respective actuating button 14 so that the upper part 15 of the same is elastically deformed and the push button 7 is actuated by the respective lug 16.

Simultaneously with the actuation of the push button 7, the light source 8 lights up, which can be seen through the lens 13 on the outside of the housing 2.

Due to the elastic flexibility of the material used for the actuating button 14, the upper

Part 15, when the pressure is removed, immediately return to its

original curved shape, so that the wart 16 from the push button 7 and the activation of the electronic circuit arrangement 5 is thus interrupted. At the same time, the light source 8 also goes out.

The remote control device according to the invention has proven to be robust and handy and can be manufactured cost-effectively.

Inserting the control buttons and the lens into the respective openings is quick and easy and ensures a secure seal against the ingress of dust, moisture, etc. into the interior of the housing.

The raised edges surrounding the openings offer the special advantage that the user can safely feel the respective button without looking.

A further and not to be underestimated advantage of the remote control device according to the invention is that

it has no protruding or breakable parts, so that it can be carried comfortably and safely in a handbag or coat pocket or stored anywhere can be stored in a car, for example.

In addition, the described remote control device offers

the possibility of personalization by adding markings, patterns or other decorative elements to the case.
