Definitions
- the invention relates to a hand switch for electromotive furniture drives with a Housing, which is equipped with push buttons that trigger functions interact with switching elements installed inside the housing.
- the hand switch in question is designed so that, for example, one or several furniture components, such as. B. the head and foot parts of slatted frames upwards and can be moved down. Depending on the design of the furniture will be a or two engines needed. As a result, the hand switch has a corresponding one Number of push buttons equipped.
- the arrangement can be made in this way that a push button is available for the up and down movement of a piece of furniture is, and that in the event that the furniture with several adjustable components is equipped, this by pressing a single push button together be adjusted in the same direction.
- the previously known hand switches are equipped with a control board on which For example, microswitches are applied when operating associated Push buttons trigger the functions.
- Such hand switches have proven their worth, disadvantageous is the relatively high design effort and the resulting contingent costs, which are correspondingly high.
- the invention has for its object a versatile hand switch to create with structurally simple switching elements.
- the task is solved by the switching elements from contact plates and consist of at least one contact spring made of electrically conductive materials.
- the complex and expensive microswitches are eliminated. This makes the execution much easier and cheaper.
- the arrangement is such that when pressing a push button through the Contact spring or closed by the contact springs of the electrical control circuit so that the function is triggered.
- the contact plates are arranged one above the other that a contact plate makes a break contact and the another forms a working contact, and that at least between the contact plates a contact spring is arranged.
- the number of contact springs depends on the Number of functions to be switched using the hand switch. This training achieves a particularly reliable design, due to the rest and work contact.
- the contact plate forming the normally closed contact lies in a particularly advantageous manner facing the push buttons and the contact plate forming the working contact Pushbuttons facing away, the contact springs on the in the rest position Rest contact contact plate form and when actuating one or more Press the button against the contact plate that forms the working contact.
- the carrier plate of the Hand switch is designed as a printed circuit board, to the conductor of which the cables are connected, for example, are soldered on.
- This version is also inexpensive. The decision as to which of the two versions is used is based according to the respective use cases.
- the hand switch 10 shown in the figures has a housing which in illustrated embodiment of an upper shell 11 and an associated Lower shell 12 is made.
- the two shells 11, 12 delimit the interior of the housing, by placing several contact plates one above the other in the following order Form of a functional package are arranged.
- a contact plate 13 which forms a normally closed contact.
- insulating plate 14 which has the contact springs 15 follow, which a carrier plate 16 follows, the outer edges of the outer edges protrude the insulating plate 14.
- the carrier plate 16 guides the push buttons 20 to 25 and limits their stroke.
- the contact plates 13 and 17 are double T-shaped or H-shaped.
- the contact springs 15 are angular, with one leg is kinked relative to the plane.
- the push buttons are in sets of three in the upper shell 11 used.
- the hand switch 10 is equipped with a power supply cable.
- the two outer push buttons 20, 21 facing away from the power supply cable 19 Blocks are for the same function of the head or foot part Slatted frame suitable, for example for lifting or lowering.
- the one in between lying push button 22 is actuated when the push buttons 20 and 21 triggered functions are to take place simultaneously.
- the two outer push buttons 23, 24 of the set facing the power supply cable 19 in turn loosen the same function from two different components, for example lowering the headboard or footboard of a slatted frame. Will both functions required at the same time, the intermediate push button 25 is actuated.
- the push buttons 22, 25 therefore trigger the same function as if the Pushbuttons 20, 21 and 23, 24 would be operated simultaneously. This will make the operation facilitated.
- the hand switch 10 is also designed so that between the one forming a block Contact plates 13 to 14 and the power supply cable a compartment for one or several batteries 26, 27 or for rechargeable batteries is provided in the event of a power failure lower the components to be adjusted. Housing the batteries 26, 27 or the batteries has the advantage that the change is easy can, because the hand switch is always accessible.
- the furniture drives are normally difficult to access, as for example with a bed below the Slatted frames can be mounted. Changing the battery is therefore a high Associated effort.
- the outer pushbuttons 20, 21, 23, 24 are selected so that the intermediate push buttons 22, 25 overlap them.
- the outer pushbuttons 20, 21, 23, 24 are provided with arcuate cutouts.
- the lower shell 12 is equipped with a battery cover 28, the one covers a sufficiently large opening.
- the housing is provided with an arcuate hook 29, to hang the hand switch 10 on suitable objects when not in use. This hook can be formed in one piece with the lower shell 12. Appropriately However, it is also when it is clipped onto the lower shell 12.
- While the Contact plates and the contact springs made of an electrically conductive material are the upper shell 11 and the lower shell 12 and the battery cover 28 and the hook 29 made of a plastic.
- the arrangement is such that a contact spring 15 is always actuated when a push button 20 to 25 is actuated, which closes the necessary control circuit.
- 3 and 4 show the mutual overlap of the push buttons 20 to 25, so the hand switch 10 is given a width which is favorable for gripping. Furthermore these figures show that one leg of the angular contact springs 15 is bent is.
- the carrier plate 16 is in a second embodiment Printed circuit board.
- the power cables are then soldered to the circuit board.
- the contact plate, in turn, the contact springs 15 are assigned to the respective To close circuits.
