Definitions
- the invention relates to a key, in particular for actuation a steering or ignition lock of a motor vehicle.
- Such keys have a key handle on the Key shaft with a mechanically coded key bit is attached.
- a key is known from document FR 1 538 140 A, the handle is made of an elastic material.
- the Handle can be pivoted with the key shaft via a hinge connected so that the shaft is releasably attached to the handle and when a force is exerted on the handle swings away so that the risk of injury is reduced becomes.
- the problem of the invention is to create a key protection from injury when a person is against pushes the key handle.
- a key 1 ( Figure 1), in particular for actuating a Steering or ignition lock of a motor vehicle has one Key handle (hereinafter referred to as handle 2) on via a key shaft (hereinafter referred to as shaft 3) a key bit (hereinafter referred to as beard 4) is fixed with a mechanical coding.
- the beard 4 and the shaft 3 are in a keyhole 5 one Castle 6.
- the shaft 3 is fastened elastically (resiliently) to the handle 2 with the aid of an elastic fastening means (hereinafter referred to as holder 7) (for better understanding, the area of the key 1 around the holder 7 is shown in the figures as a section and not as a plan view ).
- the holder 7 can be made on the one hand from an elastic, resilient material and / or on the other hand can be designed to be resilient due to its shape in the form of elastic connecting webs 8 (here S-shaped). If, for example, an axial force F 1 (represented by the arrow in FIG. 1; direction of force parallel to the axis 3 ′ of the shaft 3 and towards the lock 6) acts, the handle 2 becomes against the lock 6 due to the elasticity of the holder 7 pressed.
- Such an axial force F 1 can arise, for example, when a person unintentionally presses or pushes the handle 2. Since the handle 2 is resiliently connected to the shaft 3 via the holder 7, a risk of injury to the person is reduced.
- a lateral force F2 (FIG. 2; see arrow) can also act on a side of the handle 2 facing away from the lock 6.
- the handle 2 is bent by a bending angle ⁇ with respect to the axis 3 'of the shaft 3 (original position of the handle 2 is shown in dashed lines in FIG. 2), since the holder 7 by its individual shape or by the elastic material from which the Bracket 7 is made, resilient acts.
- the size of the bending angle ⁇ depends on the size, the direction and the point of application of the force F 1 or F 2 .
- the lock 6 in turn can be designed so that the Handle 2 from a certain bending angle ⁇ against the housing of the castle 6 abuts. If the handle 2 is additional still has an elastic cap, not shown, so the shock is additionally dampened. Depending on the hardness and elasticity of the material used for the holder 7 can be prevented be that the handle 2 breaks off from the shaft 3.
- the bracket 7 must not be too soft, so that the shaft 3 in the lock 6 can still be turned by hand can. But you mustn't be too adamant about it either also high forces and shocks, for example in the event of a knee impact on the handle 2, taken up by the elastic holder 7 become.
- Predetermined breaking points 9 are tapers in the material, which are produced, for example, by indentations. Predetermined breaking points 9 can also be produced by a material which is only present in a narrowly limited area and which, because of its lower elastic limit than the other material of the handle 2, is suitable for such an application (above the elastic limit there is a plastic deformation, ie if the force is too great, the material tears or breaks).
- the predetermined breaking points 9 can be arranged in the vicinity of the shaft 3 his. However, turning the key 1 hardly possible in lock 6 when handle 2 broke off is. For this reason, it is advantageous if the predetermined breaking points 9 arranged further away from the shaft 3 are. This leaves enough leverage with which a sufficiently large torque can be exerted on the shaft 3 can so that it can be rotated in lock 6.
- the key 1 can be used for mechanical actuation or electrical actuation of the lock 6 can be used.
- a transmitter arranged in a handle housing 10 (FIG. 3) and / or receiving unit through which coded signals transmitted or received wirelessly (via infrared or radio) become.
- the handle housing has 10 buttons for sending signals 11 on, the coded signals generated when actuated and then via a transmitting and receiving antenna be sent out.
- the handle housing 10 is advantageously in a receiving body 12 inserted and fastened there by snapping.
- the receiving body 12 and the handle housing 10 Lugs and notches on, for the sake of clarity are not shown in the figures.
- the receiving body 12 has the elastic holder 7 to which the shaft 3 is attached is.
- the handle 2 is thus opposite the shaft 3 kept resilient.
- the holder 7 can have grooves 13 (FIGS. 3 or 4), by means of which an elastic bending of the handle 2 relative to the shaft 3 is facilitated.
- the grooves 13 can also protrude so deeply into the material that a predetermined breaking point 9 is created. If the force F 1 or F 2 on the handle 2 becomes too great, the handle 2 breaks off in the area of the grooves 13.
- the magnitude of the force F 1 or F2 at which the handle 2 breaks off depends on the material used and the shape of the holder 7. Small forces, on the other hand, have little effect, since such shocks are absorbed because of the elasticity of the holder 7, so that the handle 2 bends only briefly with respect to the axis 3 'of the shaft 3 and then returns to its original position.
- the holder 7 is preferably made of an elastic material, such as a plastic (for example polyamide) reinforced in part with glass fiber, so that the handle 2 is elastic relative to the shaft 3 when a force F 1 or F2 on the handle 2 attacks.
- the holder 7 thus acts like a spring with a spring constant depending on the material and shape with a limited deflection.
- the grooves 13 through which the handle 2 is also bent enabled can on the inside of the handle 2 (like shown in Figure 3) or on the outside (as in Figure 4 shown) be attached. You can also have several Grooves 13 may be arranged in the handle 2 (see FIGS. 1 and 2).
- the handle housing 10 separable from the receiving body 12 the advantage that the receiving body 12 is universal for many Locks can be used.
- the handle housing 10 with the The sending and receiving unit is only needed at the end of production a motor vehicle or only at the customer together with the Receiving body 12 can be assembled into a unit. Before that is starting the motor vehicle with the receiving body 12 possible, which offers enough surface for this. Because with the approximately U-shaped shown in Figures 3 and 4 Receiving body 12 can already be operated mechanically (Turn the key 1) of the lock 6 made be when a user on the two legs of the receiving body 12 attacks.
- the key 1 in the form shown is preferred suitable as key 1 for a steering or ignition lock.
- the ignition lock is located next to the steering column, the Knees on handle due to impact or rear-end collision 2 of the key 1 push more or less strongly.
- the risk of injury for the knee by the invention Key 1 reduced.
- the key 1 can also be a key 1 for office furniture, such as a desk, through which the risk of injury when a part of the body hits the handle 2 is reduced because the handle 2 with the flexible bracket 7 at least partially absorbs the impact.
- the invention is also suitable for other applications where the danger there is a person on the handle 2 of a key 1st can accidentally toast.
- the handle 2 or the receiving body 12 can be made in one piece be made of the elastic material. But it is enough even if only part of the handle 2 or the receiving body 12 is elastic, this part on the rest Handle 2 or receiving body 12, for example Glued or fused is attached.
- the receiving body 12 and the handle housing 10 can also be made in one piece his.
- the shaft 3 preferably has at least one radially circumferential one Groove and / or holes in which the holder 7 engages.
- the shaft 3 is attached to the handle 2.
- a such attachment can be done, for example, by injection molding getting produced.
