DE4423721A1 - Retraction and covering the motor car mascot, preventing injury or theft, - Google Patents

Abstract

The system translates a solid body with respect to it's surroundings. It is operated by either of two switches. The first (28) is external, for example, may be operated by the vehicle central locking system when the door is opened. The second (29) is operated manually, and is in series with the first. Closing these switches (28,29) activates the relays (25,26) and solenoid valve (37), to retract the pneumatic cylinder (11) and hence open the hole closure plate (9). The retracted cylinder (11) trips the position switch (19), the relay (24) is energised, and the motor is started via the switch (31); hence the mascot (1) is exposed. Should either operating switch (28,29) be opened, current flow is interrupted, and all relays (24,25,26) drop out.

Description

There are already a number of problem solutions in the literature and in the case of older property rights have been described, which, however, does not address the problem underlying the invention solve.

For example, a radiator figure is described in the Swiss patent specification 355366, which with a Tiltable foot arranged in a base of the cooler and by a spring in the Normal position is pulled, in which the hood ornament is approximately at right angles from the hood protrudes. In the event of an accident or when colliding with an object, it bends this hood ornament resiliently back, to avoid injuries. This The problem always arises when sharp contact breaks at the hard contact Hood ornament can arise. The described solution eliminates the risk of However, injuries are not avoided because the hood ornament is also folded down protrudes beyond the smooth radiator surface. An anti-theft device is described by the System also not given.

In a further development of this problem solution, a retractable radiator figure is described in the event of danger, the system inside the hood or body disappears leaves, so that the risk of injury - caused by a break in the hood ornament - can be reduced.

The solution is achieved in that at least 2 cooperating snap springs are provided, one end of which with the motor vehicle and the other end of which retractable part is movably connected, such that the springs in each end position of the retractable part are in a stable position. This is said to ensure be that the hood ornament or a similar projecting part within Fractions of a second within the body structure disappears before a touch or injury can occur. This movement is supposed to be triggered by the impulse that in the event of an impact at any point on the vehicle. Preferably there are described snap springs from two, part-forming leg springs, the free ends are articulated on the part to be sunk and their connected ends on the motor vehicle.  

Such spring structures have been described several times, for. B. in the AS 1480437. They serve e.g. B. to the engine or trunk lid both in the Preload the closed position as well as the open position in order to make 2 stable ones Realize positions. The transition from one stable situation to the next has to be done here however done by hand. The opening of the trunk must not be caused by an impact or Brake impulse are caused.

The problematic function of such sinking solutions is already evident here. With strong Braking maneuvers or when slamming a door would cause the sunken hood ornament from the lower unstable state jumps into the upper unstable state and offers - depending on Spring tension - due to the speed of the state transitions the possibility of Injuries. In addition, the theft of the hood ornament is of course easy through this Realizing the visible door and gate open.

A car radiator figure is also known, which is located above one at its lower end Bearing journals and a bearing dome bearing the latter and lying in a joint socket, is hinged and rotatably mounted, one below the bearing dome Clamping pressure-setting compression spring and a spring sleeve containing the latter is provided, as well as a cross over the upper part of the bearing dome, with a Passage opening provided for the bearing journal and on the edge of one in the radiator plate existing installation opening to be fitted and below that the Installation opening edge of the radiator plate, which allows to be clamped in between Joint socket and the spring sleeve at least partially encompassing fastening sleeve is provided.

Here too, the known problem is to be solved, that for security reasons one on the Car cooler standing vertically, creating a risk of injury by a horizontal extending axis foldable, and moreover about a substantially vertical extending axis should also be designed to be rotatable. These demands are with the known radiator figures can only be realized to a certain extent because of the Bearing pins in the dome are limited in their ability to move and the latter in the socket are only rotatably supported to a limited extent. With hard contact is therefore with these Figures with breakage, the formation of sharp edges and a potential risk of injury to count. In addition, theft protection is not by retracting the hood possible.

The invention is therefore based on the object, in part contrary requirements vertical mobility, theft protection, selective realization of the accident risk in one to connect mechanically and electronically simple and reliable solution.  

The object is achieved in that, in the device described by the inventor, the switch ( 28 ) is connected to the locking system (e.g. central locking) which provides access to the motor vehicle (which is switched when the car door is opened) and the switch ( 29 ) by manual actuation - in combination with the switch position of switch ( 28 ) - the device can be controlled or activated.

In the solution according to the invention, when the switches ( 28 ) and ( 29 ) are actuated, the relays ( 25 ) and ( 26 ) and the solenoid valve ( 37 ) are switched, and then - in continuation of the function - the closure plate ( 9 ) due to the switching action of the solenoid valve ( 37 ) is actuated via the cylinder ( 11 ).

It has also turned out to be advantageous that the retracted cylinder ( 11 ) actuates the read switch ( 19 ), the relay ( 24 ) being actuated in the activation position and subsequently the motor ( 16 ), which starts the radiator, via the switch ( 31 ) ( 1 ) move to its end position. When Fig. (1) is in the end position, the switch ( 31 ) switches off the motor ( 16 ).

If - as suggested by the inventor - the switches ( 28 ) and ( 29 ) are actuated again, the current flow is interrupted and the relays ( 25 , 26 , 27 ) are switched to the basic position.

In a configuration according to the invention, the deflection roller ( 3 ) is made of polyethylene, while the fastening element for round steel ( 2 ) consists of metal and fixes the rod ( 17 ) by means of friction locking.

A possible embodiment of the invention is shown in the drawings. It demonstrate:

Fig. 1

The cooler figure ( 1 ) is guided with the holder ( 5 ) and connected to the drive cable ( 23 ) by means of the retaining screw ( 6 ) via the fastening plate ( 8 ) and the fastening bracket ( 7 ) fixed thereon. This is passed over the deflection rollers ( 3 ), which receive the functionally necessary pretension by means of the holder ( 15 ). The drive cable ( 23 ) is moved in both directions depending on the direction of travel via the motor in a plastic housing.

The movement is guided by the guide tubes ( 4 ), which are arranged so that they can move vertically on the rods ( 17 ). The movement is limited by the stop sleeves ( 10 ) with a lateral screw connection. The impulses for the top and bottom dead center required for the switching operations take place via the microswitches ( 13 ) and the holder for microswitches ( 14 ). The pneumatic cylinder ( 11 ) is fixed by means of the fastening part ( 12 ) and acts via the cylinder rod ( 36 ) on the closure plate ( 9 ), which is mechanically prescribed its radius of movement via the hinge ( 20 ).

The actuation and control elements required to implement the movement process are shown here. The vacuum container ( 34 ) is connected to the check valve ( 35 ). The vacuum container ( 34 ) is connected to the cylinder ( 11 ) via the solenoid valves ( 37 , 38 ) by means of a fork line. The circuit connections of the relays ( 24 , 25 , 26 ) and the switches ( 28 , 29 , 30 , 31 , 32 , 33 ) are shown.
