Abstract

The invention describes a double pedal for the actuation of gas and brake with one foot in a motor vehicle, consisting of two independently operable tread plate parts which are pivotally mounted at one end in a substantially common fixed axis and at the other, free and pivotable End of the accelerator or brake cable starts.

Description

The invention relates to a double pedal for the actuation of Throttle and brake with one foot in a motor vehicle according to the preamble of claim 1.

From the illustrated "Stern" 7/2002, page 23 known a double pedal for the actuation of gas and brake with one foot too use, which however consists only of a single step plate. This tread plate is pivotable on a horizontal axis free, pivotable end of a relatively long swivel lever stored. The swivel bearing of the swivel lever is fixed in one stored hinge added. So it is a push-turn pedal. To brake, the footplate must be pressed through the entire pressure of the foot (without swiveling) actuated to allow the long, one-armed lever to be pivoted. In order to accelerate, however, the tread plate must be around the horizontal axis be pivoted at the front free end of the pivot lever, whereby the throttle cable is actuated becomes. It follows from this that a great mechanical effort for the realization of a such construction is required. In addition, the relatively long swivel lever takes at the front free end of the tread plate is arranged, valuable Space in the footwell of the vehicle and represents an additional source of danger in the event an accident.

There is also the disadvantage that the axes for the accelerator and for the brake pedal at different points on the lever and spatially apart are formed remotely, creating undesirable mechanical play arises and the design effort is greatly increased.

By arranging a swiveling step plate at the free end of a long swivel lever there is the further disadvantage that for actuation the brake cable is relatively large To overcome swivel paths are.

Such a pedal is also not adjustable and adaptable to different shoe types, so for example the actuation with a shoe that wears a heel, is difficult and can cause accidents can.

There is no defined rest position for the foot because the foot in A kind of protective posture must be placed on the step plate, without swiveling them forward in the sense of a braking movement. The driver must therefore always ensure that his foot is in one holds the correct position on this pedal and only with the heel the tread pivoted without striking the front tread surface. At a Incorrect operation can result in that during braking Accelerator pedal pressed is, which greatly deteriorates the braking effect.

Cases have been reported in the US at which even separate operation of gas and brake over two separate pedals had caused serious accidents because of the user accidentally gas with both feet and applied the brake at the same time. This danger also exists with the double pedal known here.

The object of the invention is therefore based on a double pedal for the actuation of gas and brake with a single foot in a car. to continue training that a much simpler structure with a reliable Function guaranteed is.

To solve the task the invention is characterized by the technical teaching of claim 1.

Essential feature of the invention is now that the tread plate made of two independently operable Tread plate parts that are in a substantially common stationary axis each with one end pivotally mounted are.

According to the invention, it is a thrust rotary pedal waived, but it becomes a pure double pedal from about 1/3 divided to 2/3 divided tread plate proposed, in which the rear tread part for actuation the brake and the front tread plate part for actuating the Accelerator cable is used.

With this technical teaching the main advantage is that only two swiveling movements, the above a substantially common mechanical axis take place for Operation of the one or another function of the vehicle. to lead.

This means incorrect operations, as they would be possible with a push-turn pedal, are definitely excluded. It is important here that the common axis between the two Footboard parts rests on a stationary bearing column and this bearing column Abutment for the foot sole forms.

Because of this abutment it is not possible, that the foot sole at the same time the front step plate part and the rear step plate part actuated because this from the pillar with the common axis mounted on it is prevented.

This gives the other major advantage that now the entire foot sole stored in the manner of a rest position on both tread plate parts can be.

That is, it is easily possible to use the toe tip on the front part of the footplate assigned to the gas and the Fußhacke on the rear step plate part (which is assigned to the brake is to be filed because a joint actuation of both parts by the Common fixed axis is definitely avoided on the stationary bearing column is stored.

It is not necessary to find a solution, that the two tread plate parts absolutely run in one plane. These footboard parts can also be used against each other and for example an angle from Z. B. 300 ° or have the same, so that they have a flat V-shape to each other form. this leads to that the foot tip stable on the front step plate part and the heel of the shoe can be stably stored on the rear step plate part without that the two tread plate parts can be operated together.

The job has the other The advantage that the response sensitivity is significantly improved can be because ready z. B. the front tread part, which operates the throttle cable only with little adjustment play from the angle position can be pivoted into a lowered pivot position. This is because the fact that with the tip of the foot, which essentially rests on the front part of the step plate, a very high power transmission due to the leverage exerted by the foot exercise can and for the rest a very sensitive activity of the accelerator pedal (front step part) with the tip of the foot possible is.

The same also applies to the brake pedal, which is operated with the heel of the shoe, because in known Wise very high powers exercised can be. The longitudinal axis of the exercising Lower leg and tibia open directly into the heel of the shoe, so that there is an immediate power transmission a high heel force on the heel of the shoe and thus on the back Footplate part for actuation the brake possible is.

Because with the toe tip can act much more sensitively, it will be in an advantageous embodiment the invention preferred when the front tread plate part the throttle cable and the rear step plate part is assigned to the brake cable. hereupon however, the invention is not limited. It can do the two functions also be reversed in an analogous manner.

For the rest, it is not necessary for the invention that the two tread plate parts over appropriate mechanical linkage are connected to the gas or the brake cable. It can do any transmission from the movements of the tread plate parts for the corresponding gas or Braking function of the vehicle. be used. In particular, electrical Sensors are used, as is wireless transmission the corresponding movements of the tread plate parts on the assigned functional parts of the vehicle. and it is also possible that you have, for example, a brake cam directly in the floor area arranges the rear step plate part so that the brake over the Type of pestle press to can.

Likewise, it is not necessary to find a solution, that the two tread plate parts are of the same size. These can be done without further in size from each other deviate, which is also a significant difference from the beginning State of the art mentioned is where a continuous, only in one Axle swiveling step plate was proposed.

In this way, the tread plate parts can also to different needs be customized by users. For example, it can be provided be that with high-heeled shoes another one, the brake assigned step plate part is used, which is preferred is then designed to be exchangeable.

Another major advantage of Invention is that only a single, essentially horizontal Axis on the stationary bearing column needed becomes. The rear step plate part with its is on this axis stored front end and - over a Split separated - is on the same axis the rear part of the front tread part - which the brake is assigned - also stored there.

The one facing away from the axis Sides of these two tread plate parts are over linkage or over others articulated bearing elements on a common actuating part attached, which is also in a horizontal axis in the area a storage column is arranged.

The abutment for the swiveling ends of the both tread plate parts is by appropriate linkage and one rotatable on the rod mounted push rod bearing formed to the two tread plate parts to keep in a certain angular position in the starting position.

The invention is based on this, however not limited. It can also be provided that the respective pivotable ends of the two tread plate parts on assigned energy stores, such as z. B. spring elements, and only the pivoting movement of these two tread parts in any way the gas or the brake cable is forwarded.

Such energy storage on which the pivotable ends of the tread plate parts can rest, for example mechanical springs, elastomer springs, hydraulic springs or other energy stores.

These energy stores only ensure a defined one Swivel position of the two tread plate parts in the rest position and set the respective step plate part in this rest position after the activity back again.

The subject of the present invention arises not only from the subject of the individual claims, but also from the combination of the individual claims.

All in the documentation, including the Summary disclosed information and features, especially the spatial training shown in the drawings claimed as essential to the invention, insofar as they are used individually or in Combination versus the state of the art are new.

The invention is described below of just one way of execution illustrative drawings explained. Here go from the drawings and their description essential features and advantages of the invention.

Show it:

1 : schematically in section a double pedal according to the invention,

2 : Top view of the double pedal after 1 .

3 : the function of the double pedal when accelerating,

4 : the double pedal in the rest position,

5 : schematically the angular position of the two tread plate parts to each other,

6 : the function of the double pedal when braking.

In the 1 and 2 is shown schematically on a base plate 1 two spaced-apart storage columns 4 . 6 are arranged. In one pillar 4 are in a common axis 5 the front end of a rear tread part 3 and the rear end of a front tread part 2 each pivoted.

The two tread plate parts 2 . 3 are pivotable independently of one another, and for this reason there is a gap 23 between the two mutually associated ends of the tread plate parts 2 . 3 intended.

The swiveling part of the rear step plate part 3 is fixed with one end of a brake cable 13 connected. Accordingly, the step plate part 3 in the direction of the arrow 16 the brake cable is also activated 13 operates and operates the brake of the motor vehicle.

The front, pivotable end of the front tread part is analogous 2 over a chain 10 with the throttle cable admission 11 connected. This, in turn, can be pivoted on the bearing column in a horizontal axis 6 stored and at the throttle cable intake 11 the accelerator cable sets 12 on when the footplate part is actuated 2 in the direction of the arrow 17 is operated.

The brake cable sets a brake cable holder 14 on the push rod bearing 7 on.

It was already pointed out in the general part of the description that the invention is not restricted to the actuation of the two tread plate parts 2 . 3 on the one hand via the operating rod 8th and on the other hand over the chain 10 on the common horizontal axis in the bearing column. Other mechanical energy stores can also be used, which are the two tread plate parts 2 . 3 hold in the pivoted ends in the defined rest position and ensure a reset after actuation.

It is only sufficient here, at the respective pivotable end of the respective step plate part 2 . 3 directly the throttle cable or the brake cable itself or

corresponding plunger for the actuation of Throttle and brake to be placed directly there.

The chain 10 for the operation of the throttle cable 12 otherwise runs over a ring gear 15 , the non-rotatable with the throttle cable admission 11 is connected, on which in turn the throttle cable 12 attaches.

It can be provided that the twist of the throttle cable receptacle on the horizontal axis in the bearing column 6 is adjustable, for which a corresponding locking screw 25 is provided.

It can also be provided that instead of the chain 10 and the associated ring gear 15 a toothed belt is used, which is also used to turn the throttle cable 11 provides.

It is not necessary for the rest that the brake cable holder 14 and the throttle cable intake 11 lie in a common horizontal axis. It can be used for these two parts 11 . 14 separate, independently rotatable horizontal axes can also be provided.

For construction reasons however it is preferred if a common horizontal axis is used on which the one part can be rotated independently of the other part is arranged.

The displacement of the tread plate parts 2 . 3 is in the direction of the arrow 18 . 19 via the assigned actuators 9 . 10 transferred to the common axis.

This is then the throttle cable intake 11 and the brake cable mount 14 independently in the directions of the arrows 20 and twisted in the opposite direction.

The 3 shows as an example that the front footplate part is very sensitive with the tip of the foot 2 in the direction of the arrow 17 can be operated, which then the throttle cable intake 11 in the direction of the arrow 21 is twisted and the throttle cable 12 is operated accordingly.

The 4 shows that the sole of the foot is in the rest position on both tread plate parts 2 . 3 rests without the risk of the two tread plate parts being pressed through the foot 2 . 3 are actuated accidentally because this is due to the axis - centered on the sole of the foot 5 is prevented.

The 5 shows that for the purpose of sensitive movement of the two tread plate parts 2 . 3 this at an angle 22 can be employed to each other. However, the invention is not restricted to this. The angle can also have a size of 180 °, as a result of which the two tread plate parts then merge into one another in alignment. In the exemplary embodiment presented, the angle 22 about a size of 160 °.

6 shows a very strong braking force across the heel of the shoe on the rear tread part 3 can be exercised, which then the actuating rod 8th pivoted and over the articulated push rod 9 the brake cable mount 14 in the direction of the arrow 20 pivoted.

The invention is not based on the use of a common axis for the two mutually associated and pivotally mounted ends of the two tread plate parts 2 . 3 limited. It can also be provided that each step plate part has its own horizontal axis and these two axes are arranged parallel to one another at a short distance. For example, the front, rotatably mounted, part of the step plate part 3 in a first horizontal axis on the pillar 4 stored and at a short distance and parallel to it is the rear part of the front tread part 2 in another horizontal axis also on the pillar 4 rotatably mounted. Although this arrangement increases the mechanical effort for the production of the double pedal, it may have the advantage that a larger neutral intermediate layer between the two tread plate parts 2 . 3 is given by what. the sole of the foot becomes more stable. The expression “substantially common axis” was therefore used in claim 1 to make it clear that instead of one axis, two parallel axes spaced apart from one another can also be used.

It can also be provided that the gap 23 is bridged by a stationary bridge on which the sole of the foot has a larger surface to rest on. This bridge is arranged in the manner of a U-shaped bracket over the gap and has an upper contact surface which is approximately parallel to the plane of the two tread plate parts. However, it has no connection to one of the two tread plate parts, but is fixed on the bearing column 4 attached. The two U-legs of this bridge then grip one side of the bearing column 4 on.
