Description

object The present invention is a storage compartment according to the preamble of claim 1.

Storage compartments are in the field of vehicles, especially motor vehicles, well known. Usually show the storage compartments one formed between a bottom and a closable lid Cavity on, with the lid with a mechanism for opening and Close the Storage compartment is provided. Furthermore, locking mechanisms or Locking devices known which the storage compartments in the closed or open Hold or lock in position.

Such a storage compartment is from the DE 100 48 587 A1 known. The storage compartment disclosed there has a lid guided in scenes, which is brought by means of a locking device from the closed position to the open position. To close the locker, this must be closed by means of mechanical pressure on the lid, the locking device having a spring which is tensioned in the closed position. Only then is it possible to automatically convert the storage compartment to the open position after the actuation of a push-push mechanism for opening. The lid does not move abruptly, but slowly and subdued from the closed to the open position. Other such storage compartments are from the DE 200 05 552 or the DE 102 51 813 A1 known.

A danger emanates from the stowage compartments when they fall, for example, in the event of a rear or front impact or a sudden strong braking or close uncontrollably. This can cause injury to passengers. A measure to prevent this is, for example, from the DE 100 09 291 A1 known. Thus, that storage compartment has a mechanism which holds the open lid in the event of an impact or a strong deceleration in the open position.

Storage compartments will be often used as a holder of multimedia devices, especially navigation devices. It can the multimedia devices preferably be plugged connected to a holder. In the event of a rear impact, the navigation device or the multimedia device from the Release bracket and so a danger to the Be in the vehicle occupants.

task The present invention is to provide a storage compartment, which suitable for it is a multimedia device or other objects in a storage compartment to prevent, in the event of an impact, a danger to the occupants.

The Task is with a storage compartment according to the features of the claim 1 solved.

The Storage compartment according to the invention has one with the lid operatively connected acceleration element, which in a rest position of a triggering device under storage is held by energy and in a release position of the triggering device is released, allowing the stored energy of the accelerator element converted into kinetic energy of the lid and this from the open Position is brought into the closed position.

in the Normal state, the cover of the storage compartment is opened by means of a locking device or a guide device held. Now act on the vehicle acceleration forces or a Acceleration, which over go beyond a predefined limit, the triggering device transferred from a rest position in a trigger position. This will be an accelerating element activated or released, which opens the lid from the open Accelerated position to the closed position, so that the Storage compartment is closed, before in the storage compartment located objects can move this out. The acceleration element is arranged such that it the energy stored in it directly or over another with the lid connected element can give the lid and the lid so moved to the closed position.

there It is particularly advantageous if the acceleration element with the locking device is connected or is in operative connection. This causes the locking device connected to the cover this to a closing movement at.

The Acceleration element can inter alia by a spring element, a gas charge, a magnetic element or an electromagnetic Be given element.

In a spring element this is held in a tensioned, ie compressed form. The stored energy in the spring element is approximately 1 2 kx 2 where k is the Hook's spring constant and x is the deflection from the unloaded rest position of the spring element.

at a gas charge is the stored energy in the under pressure stored gas, which is held in the gas charge stored. The gas charge is by the triggering device analogous to a Airbag device ignited, And now does not accelerate the gas bag, but the lid in the closed position.

at a magnetic element, which for example consists of two permanent magnets the energy is stored in the magnetic fields. there the two permanent magnets are arranged so that they repel each other. The stored energy in the resulting magnetic field leads to, that the two magnets strive for each other as soon as the triggering device actuated has been.

in the Fall of an electromagnetic element, these in the rest position the triggering device be poled so that they attract each other. Will the triggering device is transferred to the trigger position is a polarity reversal of one of the two magnets is excited, so that the repel both electromagnets now and diverge, wherein the lid moves to the closed position.

The triggering device can in the rest position the accelerator element directly or fix mechanically or electromagnetically indirectly. So can the triggering device mechanically hold a part of the accelerator element. This offers especially when it is at the accelerating element is a mechanical component.

however must be the triggering device not necessarily with the accelerating element in mechanical operative connection. So can the triggering device also electromechanical or electromagnetic, d. H. in shape a controller or an electrically controllable mechanical Device such as a switch.

In order to prevent that the storage compartment is closed even at low acceleration forces, it is advantageous if the triggering device is set so that it at an acceleration of more than 3 g, preferably more than 5 g, where g is the gravitational acceleration of the Rest position is transferred to the release position. Here, the triggering device can be in operative connection with another spring, which is compressed at the aforementioned acceleration. Alternatively, the triggering device, such as in the print font DE 10 2005 015 559 A1 shown to be trained.

In a particularly advantageous embodiment, the locking device at least a first and a second sub-element, which in the Rest position of the triggering device essentially rigidly connected to each other and in the release position the triggering device are movable against each other. In this case, the triggering device arranged in such a way be that they have a movement of the first and second subelements prevented in the rest position. In the release position, the first sub-element Released and can be so in relation to the second sub-element move against this. It is particularly advantageous if the first sub-element is guided in the second sub-element. It can, however the second subelement may be guided in the first subelement.

In a further embodiment It may be in the storage compartment to a storage compartment with a rotating act stored movable lid. Alternatively, this is also a straightforward, unidirectional movement is conceivable.

Further embodiments or features can taken from the various embodiments become.

following the invention will be explained in more detail with reference to some embodiments. It It should be noted that in the various embodiments disclosed features can be combined with each other. Show it:

1a a first embodiment of a storage compartment in the maximum open position;

1b a closed position of the first embodiment of the storage compartment;

1c a closed position of the first embodiment of the storage compartment when triggered release device;

2a , b alternative embodiments of the accelerating elements and locking device;

3 a second embodiment of a storage compartment.

The 1 show a first embodiment of a storage compartment according to the invention 1 ,

This includes a lid 2 which is about the axis of rotation 20 is rotatably mounted. The storage compartment further comprises a floor 3 , wherein the actual cavity for receiving objects between the lid 2 and the floor 3 located. That in the 1 illustrated storage compartment 1 is located at the top of an instrument panel, but may for example be arranged accessible in the center console of a motor vehicle for the rear passengers.

Furthermore, a locking device 4 present, which is a first subelement 41 and a second subelement 42 includes. The first subelement 41 is firmly with the lid 2 connected. The locking device 4 , more precisely the second subelement 42 . has a collar 43 on which an opening 30 in the ground 3 engages behind, with the lid 2 in the 1a is shown in its maximum open position A. Below the collar 43 is as part of the second subelement 41 formed a device 44 present, which is a counterpart to a push-push mechanism for holding the lid 2 is in the closed position.

In the in 1a The sectional view shown is the cross section of the second part element 42 shown. It can be clearly seen that one at the lower end of the first subelement 41 existing stamp 41 ' by an inertial trap 60 trained triggering device 6 is held. In the illustration shown, the triggering device is shown in a rest position R, which is characterized in that the punch 41 ' is held directly by the provided with a trigger spring inertial trap.

Between the upper end 42 ' of the second subelement 42 and the stamp 41 ' there is an acceleration element 5 which is formed in this embodiment as a spring element. The spring element 50 , which consists of a metal or a plastic is in the rest position of the inertial trap in the compressed, ie relative to the rest position of the spring element 60 held strongly shortened state and has stored energy, which can be calculated according to the Hooke's law.

From the representation of 1a is clearly seen that in the rest position R of the triggering device 6 the first and the second sub-element are substantially rigidly interconnected. Depending on the embodiment, the inertial trap may be arranged such that it does not allow play between the first and second sub-elements. In addition, from the representation of the 1 it can be seen that the first subelement can be guided in the second subelement.

In the 1b is the storage compartment 1 shown in the closed position B. Because the inertia trap 60 still in the rest position R, causes a pressure on the top of the lid 2 a movement of the lid or the locking device 4 down, the device 44 in a device 7 held in the closed position for holding the locking device. Since the first and the second sub-element are rigidly connected to each other, the force applied to the cover is transmitted directly to the first and the second sub-element, wherein the second sub-element clearly through the opening 30 in the ground 3 moved to the bottom.

In the 1c is the storage compartment 1 again shown in the closed position B, wherein the inertial trap 60 now shown in the triggering position. Closing the storage compartment 1 or the triggering of the triggering device has now been effected due to an occurring by a rear impact acceleration force α → of> 6 g. Due to the large acceleration α → the inertial trap became 60 transferred from the dashed line rest position R in the release position AS. This became the stamp 41 ' of the first subelement 41 no longer held, allowing a relaxation of the spring element 50 for partial conversion of the stored energy of the spring element in kinetic energy of the lid (a complete conversion is not possible energetically) and the spring element on top of the punch 41 ' pressed and this from the open position A, as in the 1a shown in the ge closed position B 'convicted. In this case, the first sub-element moves 41 within the second subelement 42 after lower, whereas the second sub-element initially remains in a nearly constant position. The constant position of the second sub-element can, for example, by a like from DE 100 48 587 A1 known mechanism can be effected. In the 1c It can be clearly seen that the second subelement 42 the locking device 4 has moved only a little down after completion of the closing process, the slight downward movement ultimately only occurs due to the coincident lid. The actual transfer of energy to the lid and the corresponding closing of the lid or the relative movement between the first and the second sub-element comes only because of the relaxing spring 50 conditions.

The difference between the closed positions B and B 'is that in the closed position B, the release device in the rest position R, that is, the first and second sub-element are substantially rigidly interconnected, and the triggering device in the position B' in the release position AS is present, that is, the first and second sub-element are movable against each other and by the accelerating element 5 be accelerated against each other. Because the second subelement 42 due to the collar 43 can not move up, the lid becomes 2 pulled down.

Generally pass between the actuation of the triggering device 6 and the associated transfer from the rest position R to the release position AS only a few μsec or msec, preferably less than 100 msec, particularly preferably less than 50 msec. The closing process triggered thereby results in a cover held in the maximum open position, due to the energy emitted by the accelerating element, within less than 200 msec, preferably less than 100 msec is transferred to the closed position. Possibly, the lid can also be transferred only in a slightly open position, wherein the slightly open position is chosen such that, although a human finger of about 2 cm thickness is not clamped, but at the same time a befindlicher in the storage compartment object can not escape from this ,

Although the in the 1 drawn triggering device 6 an inertial trap 60 is, which is triggered by a mechanical spring element, it is also conceivable to use a piezoelectric device as a triggering device, which closes a circuit in the occurrence of appropriate to close the lid leading accelerations, so that the triggering device by means of a motor from the rest position R in the Trigger position AS is transferred.

In the 2 shown alternative embodiments of the locking devices and the acceleration elements. That's how it shows 2a a locking device 4 ' which consists of a first subelement 41 and a second subelement 45 consists. The triggering device shown here 6 ' is again an inertial trap 60 which, however, partially from the outside of the second part element 45 is accessible. In this way, once a triggered inertial case of the release position AS back to the rest position R can be moved without the second sub-element 45 to have to open.

That in the 2a exemplary arranged acceleration element 5 ' consists of two permanent magnets 51a , b. These are arranged such that their north poles face each other, ie, the two permanent magnets show a tendency to drift apart. Here is the upper permanent magnet 51a mechanically fixed to the second sub-element 45 , the lower magnet 51b mechanically fixed to the first sub-element 41 connected. Now the inertial trap 60 triggered by an acting acceleration, strive for the permanent magnets 51a and 51b apart, and the one with the first subelement 41 directly connected lids 2 will be closed.

Another embodiment is found in the 2 B , The triggering device 6 '' Here is an electronic circuit 61 , The acceleration element 5 '' has two electromagnets 52a and 52b on, with the first electromagnet 52a with the second subelement 46 and the second electromagnet 52b with the first subelement 41 is firmly connected. At rest is the electronic circuit 61 switched so that the two electromagnets 52a respectively. 52b attract each other. If a corresponding acceleration leading to the closure of the cover is now measured, the circuit is actuated in such a way that one of the two electromagnets is reversed so that they diverge. In the present combination of triggering device and acceleration element, the acceleration element is electromagnetically fixed in the rest position. A mechanical holding of the stamp 41 ' as in the previous embodiments is not necessary.

A second embodiment of the storage compartment is in the 3 shown. The storage compartment 1' is in many elements with the storage compartment 1 from the 1 match.

In addition, the storage compartment 1' a bracket 8th on which in a backdrop 80 of the soil 3 to be led. On the holder is a plug-in element 81 , on which a multimedia device, in the present case a navigation device 9 , can be attached. If corresponding accelerations now occur, the inertial trap becomes 60 triggered, and the first subelement 41 moves down, with the first subelement 41 within the second subelement 45 is guided.

Furthermore, the shows 3 a push-push mechanism 10 ' , which is designed as a standard heart-shaped push-push mechanism.

The Storage compartment disclosed in this invention can be made of a variety of Materials are made. The materials include metals and plastics, in particular fiber-reinforced plastics or abrasion-resistant Plastics such as POM.

Although only one locking mechanism with two sub-elements has been described in the embodiments, it is also possible to use a locking mechanism with only one element. In that case, the accelerating element and the triggering device in the region of the connection 21 be arranged between the axis of rotation and the lid, wherein the triggered acceleration element is on the underside of the carrier 11 supports and on the connection 21 acts. However, due to the shorter lever, the accelerators need to store larger energies to close the lid completely and quickly enough.
