Description

105956 Elevator keypad "The invention relates to an elevator keypad as defined in the preamble of claim 1.

5

When constructing buildings, the aim is to get the lifts operational as quickly as possible so that they can be used during the construction phase. The finished elevator is then subjected to extremely abrasive conditions. Dust, dirt and moisture during construction and dirty hands and clothing of lift users, as well as the goods carried in the lift, result in relatively high wear during the construction period. The keyboard, in particular, is subject to heavy wear and tear as it is a part of the elevator that every passenger has to touch.

Due to the abrasive use described above and the heavy wear and tear, the building will have to be repaired in the elevator and often the entire keyboard will have to be replaced. Keyboard repair and partial replacement is a significant cost addition.

. . It is an object of the invention to eliminate the aforementioned • I i • · ·; 25 disadvantages. In particular, it is an object of the invention to provide a novel elevator keyboard which is one i 1 *. 1! simple and inexpensive and very impurities and wear resistant. It is a further object of the invention to provide a novel type of temporary elevator keypad that is easily removable after completion of a building and replaces with a new actual keypad.

The elevator keypad of the invention includes a mounting surface facing the lowest mounting base used. For example, the adhesive surface can be used as a mounting surface. On top of the attachment surface is a switch-5 layer which contains the required number of switches and is further integrated with the required cable connector. The entire switch layer is further covered by a continuous film-like protective layer having key patterns depicting the keys 10 at positions corresponding to the keys of the switch layer. Preferably, a uniform protective layer covering the clutch layer is formed by a protective tape, wherein the entire keypad consists of a flexible and flexible jacket that can be attached to both straight and curved surfaces, even over corners, by means of an adhesive surface or other mounting surface.

The keys themselves, between the protective layer and the attachment surface, may consist of various technical solutions known per se. Thus, the switch-20 hinged layer may have depressions, springs, or bubbles that form key switches.

The top layer of the protective layer used in the keypad of the invention is preferably made of a suitable plastic,: Y: 25, which can be used to make various key representations and • *. : signs. Likewise, it is easy to make a variety of * * «patterns and even blind characters, making the * * ... keyboard accessible to the visually impaired.

The keyboard of the invention can be used in elevators instead of the standard, traditional keypad keys. • · · · /> · due to its simplicity of use and construction and its ease of installation; The X 35 is also an excellent temporary keyboard that is removed from the elevator, for example, when the building is completed and replaced by the actual keyboard.

3 105956 The cable connection from the keyboard sheath can come from the edge of the sheath by pulling the cable on a suitable surface to pull the cable 5 as desired. ' In this case, for example, the cable may be temporarily taped to said surface. Another installation option is to drill a small hole in the mounting surface from which the cable is guided under the surface and glue the keyboard onto the hole, whereby the keyboard sheath covers the hole and all wiring is invisible and protected from vandalism.

The keyboard of the elevator according to the invention, which is used continuously or temporarily, has significant advantages over the prior art. The keyboard is very simple and cheap to manufacture. Installing the keyboard requires nothing more than a relatively flat surface to adhere to the appropriate mounting surface. The keypad is completely protected from dirt, dust and moisture 20, making it ideal for building conditions. In addition, the keyboard does not contain any protruding or detachable parts or projections, so it is also very resistant to external knocks and vandalism. Temporary use of the keyboard is: Y: 25 easily disconnected after use and replaced by the actual lift keyboard.

The invention will now be described in detail with reference to the accompanying drawing, in which: Fig. 1 is a top view of a keyboard according to the invention and Fig. 2 shows a top view of a keyboard according to the invention. a sectional view of a single button 4 · J of Figure 1.

35/1 shows what the temporary or permanent use of the keyboard keys according to the invention is shown on the top. In other words, the keyboard is relatively thin. a film-like layer structure having an integral protective layer 3 of plastic on its surface, with key patterns 4 indicating the positions and functions of the keys 5.

Figure 2 is a sectional view of the keyboard of Figure 1 at another key pattern 4. At the bottom of the keyboard is the adhesive surface 1, which acts as a mounting surface, by means of which the keyboard 10 can be glued to the desired mounting base. A coupling layer 2 is provided on the adhesive surface. The coupling layer comprises a printed circuit board 5 with an integrated cable connection. A metal spring 6 is provided on the circuit board to provide the flexibility of the key. The actual switch members 7, the resistor 8 associated with the switch 15, and the LED 9 illustrating the operation of the keyboard are disposed in the periphery of the key pattern. The entire structure is covered by a uniform, flexible protective layer 3 which covers and hides the entire switch structure. The keyboard may comprise only two arrow keys as shown or only one arrow key. Similarly, the keypad may include a large number of numbered keys when used in a basket, depending on the number of floors in the building.

The invention has been described above by way of example with reference to the accompanying drawings, in which various embodiments of the invention are possible within the scope of the inventive invention.
