DE3228211A1 - Economy switching device in circuits especially for hotel rooms - Google Patents

Abstract

In order to suppress current wastage, for example in hotel rooms, it is proposed that each hotel room have a dedicated circuit = room circuit which, for example, is connected in/to the main circuit or, for example, in parallel with the main circuit; means such as contact pins (34) having switching boxes (40) are proposed in order to interrupt this room circuit when the guest leaves the room, and to close the room circuit when he enters the room. Room keys (27) (in the sense of a security card or the like) are also proposed as means, which operate the corresponding, for example two, contacts (9, 14) for the room circuit on opening and closing, that is to say the room circuit is opened or closed. For safety, a further so-called safety circuit can be provided in the room. If gas or smoke develops, or flames occur, then an alarm contact is closed and the hotel management know that, for example, a fire has broken out; in this case it is possible to make the room in which this has occurred identifiable on a switchboard. <IMAGE>

Description

Economy switchgear for electrical circuits, especially Ejir hotel rooms The invention relates in particular to an economy switching device in electrical circuits for hotel rooms.

The object of the invention is to save energy in rooms - electricity and at the same time to secure the room (s). The given task is solved by the characterizing features of claims 1 and 2.

The invention is illustrated using an example.

Wherever a person is not responsible for costs himself is, is generally not saved, e.g. 9. not even on electricity. This is the case, for example at hotels too. The guest leaves the room, has the light separated, the television is running or other electrical devices in operation.

The invention forces the guest to leave the room to interrupt the now no longer required electrical circuit. The attachment should be designed, however, that the circuit in which the pulse generator is required for Security systems still under Electricity is available, so that if smoke is generated, A fire breaks out, but also if the room is entered by unauthorized persons, an alarm is given will.

Each hotel room or each hotel room group (Sute) (analogously at private rooms in houses, 10hnungen etc.) has its own circuit, which in the Main circuit of the hotel, the floor of the hotel, etc. is connected. This Room circuit has, for example, at least two contact points through which this Room circuit can be switched on and off. These two contact points lays down one according to the invention so that by pressing the key, the security card or the contact element according to the invention, the room circuit is switched on or off when the guest leaves the room, regardless of whether the guest so wishes or not; the guest is thus forced to be thrifty. In the fuse circuit there is a known signal (impulse) transmitter for e.g. gas, smoke and fire alarms or alarm.

Certain variants can be made here; z.3. can when interrupting of the room circuit, the air conditioning is still partially (e.g. with half a narrow; hangs from Klein2) continue to run anyway. The refrigerator will not be functional Switch to the room circuit because it should not be switched off, etc.

The invention is explained using 3 examples, and it shows (all basic sketches): Fig. 1 schematically shows an arrangement of the invention, with the switching on and off of the room circuit takes place via the bolt of the door lock, Fig. 2 a separate switch box, independent of the door lock to also open and close the room circuit, Fig. 3 and 4 arrangements of contacts or contact surfaces on the bolt, Fig. 5 a Similar embodiment to FIG. 1, with the opening and closing of the room circuit by tilting or rotating an element and Fig. 6-7 shows a similar arrangement according to Fig. 2, but the contact is not made by e.g.

Room key, but through a separate contact element.

The invention relates to all types of locksmiths e.g. cultivation, Applied locks, cylinder locks, etc. In door 30 (indicated schematically) a known lock is mounted; here only the bolt 1 is set, which is guided in guides 2 of the housing wall of the lock. In the wall 29 is a recess 4 is provided into which the bolt 1 engages when / opened. here the switching device is housed, which opens and closes the room circuit. In the example shown, a contact pin 5 can be seen; on this contact pin 5 acts cLne schematically Compression spring shown 7. At the ContaXtstiZt 5 a clay sheet 6 is provided with two contact pins.

In the position shown (the bolt 1 is in the locking position; see the dashed position) the Kontaktsti £ t 5 is pushed back so that the both contact pins on the contact plate 6 are offset to the right, so not can put against the tone-Taitstelle 8.

The contact point 8 is also indicated schematically and zvar by two Yontakt surfaces that lie in the circuit, the circuit being purely schematic with (+) and (-), is indicated (this is of course not intended to mean that it is are DC circuits).

If the latch 1 is now shifted to the left out of the dashed line, the door is opened and the guest enters the room; pushes at this moment the spring 7 the contact pin 5 to the left (up to a stop, not shown) and the two contact pins of the contact sheet 6 lie against the contact the contact point 8, and since the two contact pins are conductively connected, is the room circuit is now closed. The striking plate 3 can still be seen here, through which the recess 4 protrudes.

A similar function can be seen in Fig. 5, only with the difference that there is no straight-line shift to the left or right, but a tilting movement executed vird. The bolt 1 can be designed accordingly; Here, a sloping surface 31 can be seen, which has a curved surface 32, for example cooperates and this is provided on a rocker arm 23. The rocker arm 23 can Carry out at least partial rotations because it is rotatably mounted about a pin 33, for example is. The return spring 24 (e.g. a spiral spring or the like.) Tends to the rocker arm 23 e.g. to spend in the horizontal position so that it rests against the abutment 25; one end of the return spring 24 can be attached here and the other end is locked on the rocker arm 23.

If the door is locked, the bolt 1 takes the dashed line Position, i.e. the rocker arm 23 makes a tapping movement so that the contacts 22, which are provided isolated on the rocker arm 23, release from the contact points 8, so that the Raumstromireis is open. If the bolt 1 moves into the fully extended position Position then the two surfaces 31/32 separate and the iPP lever 23 lies down against the abutment 25, whereby the contacts 22 are against the KontaXtstellen 8 and close the room circuit. Instead of a rocker arm 23 can of course other rotating or tilting elements may also be provided. In this sense but you can also use a normal switch, which should also be spring-loaded, actuate. Such switches are known.

In principle, they work in a similar way to Fig. 1 or Fig. 5.

A further variant is shown in FIG. 2, and is independent of the closure the door. The switch box 10 is, for example, near the door inside, for example, in a hotel room arranged. It consists of a housing 11 which has an insulating layer 12 counts. In addition, a guide opening 26 is provided for the key and where the beard 28 enters, contacts 9 and 14 are attached; these can of course also be provided on the opposite side. The contacts 9 and 14 are with contact represent 8 connected or trained to do so yourself. the key 27 is now inserted, then he represents the conductive connection between the contacts 9 and 14, so that the circuit is closed. All devices are now running or can be switched on will. if the key is removed, the circuit is reopened.

The guest must therefore always insert his key into the switch box 10, if he wants electricity to be available.

It is also shown here how a key 27 can be isolated. For example, in that an insulating intermediate layer between the beard 28 and handle is provided. The whole key can also be isolated and you only lant that favored contact points (which of course must be connected) free. So you could provide the back of the key with an insulating surface, when the key 27 itself is made from insulating material.

Then contacts 9 and 14 on the opposite side must be in the switch box 10 can be provided e.g. at the level of the insulating layer 12.

3 and 4 show schematically how many contact surfaces are attached to the bolt 1 could be. These can, for example (see Fig. 3) opposite each other, so that one has two contact surfaces 75 connected by a wire 17, for example. In the locked position (as indicated here) the contact surfaces 15 lie against contacts or locking surfaces 16 ', which can form contact points 8 or are connected to them.

In Fig. 4 there are two contact surfaces provided at a distance from one another 18 provided; they are connected by a conductive means, for example a wire 19; an insulating layer 20 is arranged for the bolt 1. Lie in the indicated place the two contact surfaces 18 at the contact points 8; the circuit is closed; if the bolt 1 is moved to the left or right, the circuit is opened.

Around the key 27 not always a high voltage (e.g. 220 volts) to expose and thus possibly endanger the guest, one can use the economy switchgear assign a so-called auxiliary current, which has a lower voltage, e.g. 12 or 6 Volts. The devices described are in this auxiliary circuit, so that z.9. the contact points 8 have this low voltage. If you can now inserts the key (e.g.

Fig. 2), then one need not fear that the guest himself v if the isolation of the key is unevenly free, gets a blow.

The auxiliary circuit controls the main circuit, i.e. becomes the auxiliary circuit closed, the main circuit follows and vice versa.

Part of the invention is that the switch box 10 itself is made of insulating material can be created; he then only receives conductive contacts 9, 14 or respectively. Contact points 8. In such a case, the insulating layer 12 could be saved.

The bars 1 can also be made entirely of insulating material be. This also applies to the rocker arm 23.

+ not t: lenn in the description of one with a key Is spoken about the lock to be opened, then another opening means can accumulate can be used, for example a security card.

In addition to the room circuit kar.n, a fuse circuit is integrated i.e. the fuse circuit can be parallel to the room circuit, for example switch. The fuse circuit has a task, then an alarm device in To set the function as soon as the rooms are endangered e.g. by fire, smoke, gas, etc. will. In the same way, an alarm is given if an unauthorized person enters the room, whereby a delay switch could be accommodated here so that an alarm is not given when the guest enters his room.

Such a delay switch could e.g. after ten or twenty Seconds to trigger the alarm.

A security card is understood to mean any type of legitimation card, as is customary in ATM service at banks, for example. 9 in the so-called For cash payers (cash dispensers) the card is the corresponding magnetic signal generator has, inserted into a slot provided and the payment is made; often additionally with another key or setting a six-digit secret number. The card and Ceheim number together cause the money to be issued. In a sense, a Time lock for steel doors to be opened and the application of these known device is to be used for the invention.

A special arrangement is shown schematically in FIG. Left is a switch box 40. It can be molded from an insulating housing (e.g. plastic) be, has a mounting flange 43 and has an inlet opening 41, the can be designed completely or partially conical so that the following described Contact pin 34 is easier to insert. In the area of the insertion opening 41 the two contacts 9 and 14 housed; directly to the leadership on which the Contacts 9, 14 are, a boundary wall can be arranged or - as shown - A stop 42 can be provided at a distance. now the contact pin 34 inserted, then the circuit is closed. The contact pin 34 cause the current to flow by himself, for example by creating it from copper is; or contact surfaces 35 can be provided.

In the example shown, the contact element 34 has a connecting element 37, which is provided with two slots 38, 39. Reaches into one slot the guide surface 36 of the contact pin 3n and a snug fit is fastened with a rivet or screw, gt. On the opposite rope can be in the slot 39 the room key is introduced; it is also attached there.

When the guest has unlocked his room, he has to use the contact pin Slide 34 into the insertion opening 41, otherwise its room circuit remains open. By inserting the contact pin 34, the room circuit is closed and the guest can turn on his radio, light, etc. As he left the room The room key needs, however, he must pin the contact 34 from the control box 40, which opens the room circuit. The guest is always there forced by pulling the contact pin 34 out of the switch box 40 the room circuit to open so that no electricity flows when he wants to lock his room door.

The contact pin 34 can have suitable and expedient cross-sectional shapes exhibit; The insertion opening 41 must then be designed to fit properly. The contact pin can be created as a fixed unit with the key. He can for example be attached on the opposite side of the key bit or across it.

If the contact pin 34 is, for example, at right angles to the key provided, then you save the so-called * appropriately articulated Key ring, that ensures that the guest does not put the key in his pocket. the lower one schematic representation of the key 27 with de contact pin 34) (Fig. 6a).

Zveckm & Sig will open the opening for the key 27 or the Contact element 34 has a conical design (finding funnel).

In Fig. 7, another form of contact is shown. The inner wall 45 (which is e.g. round) may have buffers 51 (plastic rings or the like); on the other hand, a plate, which is preferably designed as an insulating plate 48, is placed is. This plate 48 carries contacts 49, 50, and if the key 27 or the contact element 34 verden inserted (the contact element 34 then has no contact surfaces 35), vird the plate 48 against the force of the compression spring 46 in the direction of the contacts 49a, 50a led; the contact surfaces 50, 50a and 49, 49a lie on top of each other, whereby the contact is effected. So that the key 27 or the contact element 34 cannot slide out automatically, securing means known per se can be used be provided (clamping effect, turning the contact element 34 into a locking position etc.).

The circuit of the entire system can be varied.

For example, the air conditioning can be switched off or immediately operate a delay switch so that the air conditioning system, for example, only is shut down after half an hour. With the switching off of the circuit an emergency light can be switched on at the same time.

The inclined outer wall 44 is particularly suitable for labeling (in all languages), so that the hotel guest is informed in the same way as the system is to use.

The switch according to FIG. 7 has the advantage that there is no short circuit called Un can cause; but instead of the switch selected there, you can do all of them known switching elements that are similar or have the same effect are used there.
