Description

  The present invention relates to a footrest that can easily move a leg while driving a vehicle, and helps to prevent traffic accidents or traveler's thrombosis. Traveler thrombosis is described in 0008 for convenience.

  In the present invention, the definition of feet and legs is as follows. When emphasizing the range from the ankle to the toes, it is expressed as a foot. When it is not emphasized, it is expressed as a leg and represents the range of the body from the bottom of the pelvis to the toes.

  Depending on the vehicle model, a footrest is installed on the left side of the accelerator pedal and brake pedal at the lower part of the driver's seat.

  From the viewpoint of safety, it is considered that the conventional technique described in 0003 is effective in straddling during sudden deceleration and preventing the body from leaning forward. Also, from a health standpoint, raising the foot to a position higher than the floor alleviates the deterioration of the blood circulation of the leg due to the back of the thigh being pressed by the seat, making the leg easier sensuously Is considered to be effective.

However, the conventional technique has the following two drawbacks.
First, since the conventional footrest is fixed, the position cannot be adjusted according to the length of each user's leg.

  Leg length varies from person to person. For this reason, there are people who can ease their legs with a conventional footrest and those who are not. For those who do not, the distance from the seat to the footrest is not suitable for the length of the legs, and the back side of the thigh is compressed by the seat, and blood circulation of the legs deteriorates.

  Due to this deterioration in blood circulation, the whole body becomes tired, and there is a risk of causing concentration loss or drowsiness when driving a car, leading to a traffic accident. In addition, if blood circulation worsens excessively during long-distance driving, there is a risk of causing traveler's thrombosis.

  Traveler thrombosis is the so-called economy class syndrome. This is because, for example, when using a car, an airplane, a train, or the like, the back side of the object is pressed by continuing to sit for a long time, and a thrombus occurs in a vein in the back. It is a disease that clogs the pulmonary veins and makes it difficult to breathe, which reduces the function of the heart.

  The second is the disadvantage that there is only a use for putting a foot on the table and resting. When driving an automatic transmission vehicle for a long time, the right leg is in a state of being constantly moved to step on the accelerator pedal and the brake pedal, while the left leg is in a state of being hardly moved. This deteriorates blood circulation and causes the danger described in 0007.

Means to solve

  In order to solve the above problems, the present invention is installed on a conventional footrest, on the floor where the conventional footrest is removed, or on other places where it does not interfere with driving, and is used during driving. To do. The present invention is a footrest in which a foot pedal via an elastic body and a hinge is provided on a fixing member constituted by a rail or a jack.

The invention's effect

  In the footrest of the present invention, the rail, which is a fixing member, is attached with screws on the conventional footrest, on the floor where the conventional footrest is removed, or on other places that do not hinder driving. What can be done. In addition, the foot pedal or jack can be moved along the rail.

  With these two features, the position of the footrest of the present invention can be adjusted according to the length of each user's leg. And the back side of the thigh is released from the pressure by the seat, and the blood circulation deterioration of the legs can be alleviated.

  Furthermore, a foot pedal via an elastic body and a hinge is attached to the footrest of the present invention. By using this to exercise the leg, the effect of alleviating the deterioration of blood circulation of the leg is further enhanced. Moreover, since it gives a stimulus to the body, it becomes a mood change to prevent arousal from sleepiness, or getting tired of driving or lowering concentration due to fatigue. Therefore, it helps to prevent traffic accidents or prevent traveler's thrombosis.

  The attachment method will be described in order. The four holes a (2) in the pedal upper plate (1) shown in FIG. 2 are fixed to the four bolts a (4) in the spring hinge (3) shown in FIG. Similarly, the four holes b (6) in the pedal lower plate (5) shown in FIG. 4 are covered with the four bolts b (7) in the hinged hinge (3) and fastened with nuts.

  Next, the hole c (9) of the stopper a (8) shown in FIG. 9 is overlaid on either the hole d (10) or the hole e (11) or the hole f (12) in the pedal upper plate (1), and screwed. Secure with. Then, two bolts c (14) are inserted into the two holes g (13) in the pedal lower plate (5) and fastened with nuts. The stopper b (15) shown in FIG. 10 is inserted into the protruding bolt c (14). A state where the pedal is attached so far is a stepping pedal, which is shown in FIG.

  Next, two jacks a (18) are attached to the two holes h (16) in the pedal lower plate (5) through the ring (17). FIG. 13 shows the state of attachment up to here.

  Next, using a hole j (20) in the rail a (19) shown in FIG. Then, one end of the two jacks a (18) attached to the pedal lower plate (5) is fastened to a hole k (21) in the rail a (19) with an overlap screw and a nut. Also, the two holes j (22) in the pedal lower plate (5) are fixed to the holes k (21) in the rail a (19) with screws.

  Finally, the inclination of the pedal upper plate (1) and the pedal lower plate (5) is adjusted to an angle suitable for each user with the jack a (18) so that the footrest (23) of the present invention can be used. Become. This state is shown in FIG. Moreover, the state which attached the footrest (23) of this invention to the driver's seat leg lower part is shown in FIG.

"Effect of the embodiment"
The presence of the rail a (19) or the jack a (18) makes it possible to install the footrest (23) of the present invention at a position suitable for the length of each user's leg. Further, the angle of the foot pedal can be adjusted by the jack a (18). And by putting a foot on the pedal upper plate (1), the back side of the thigh is released from the pressure by the seat, and the effect of alleviating the blood circulation deterioration is obtained.

  Moreover, since the foot pedal is attached, the effect of alleviating the blood circulation deterioration of the leg is further enhanced by the exercise of stepping on the pedal upper plate (1). And since it gives a stimulus to the body, it becomes a mood change to prevent arousal from sleepiness coming from fatigue of the whole body, getting tired of driving, or a decrease in concentration due to fatigue. Therefore, it helps to prevent traffic accidents or prevent traveler's thrombosis.

  As another effect, when driving a car, if it is an automatic transmission car, the left leg is hardly moved. Therefore, when driving for many years, the muscles of the left leg become weaker than the right leg, and the balance of leg strength is lost. Therefore, the balance of leg strength can be maintained by moving the left leg using the foot pedal of the present invention during driving.

  By placing the footrest (23) of the present invention at a position suitable for the length of each user's leg and placing the foot on it, a good posture can be maintained during driving. That is, since the distance from the seat to the accelerator pedal and the brake pedal is equal to the distance from the footrest, the spine and pelvis can be kept in a natural position. This alleviates driving fatigue and helps prevent traffic accidents caused by reduced concentration or sleepiness.

  Because of the presence of the stopper a (8), the pedal upper plate (1) matches the shape of the toe as compared with the case where the pedal upper plate (1) is flat. Further, since the stopper b (15) has a spring a (24) as shown in FIG. 10, the pedal upper plate (1) is stepped on, and the impact transmitted to the leg when it hits the stopper b (15). Can be relaxed. This makes it easy to step on.

  The presence of the stopper a (8) and the stopper b (15) helps to prevent the body from leaning forward and striking forward during sudden deceleration. Since the pedal upper plate (1) has holes d (10), holes e (11), and holes f (12), the position of the stopper a (8) can be adjusted in three stages. As a result, the foot pedal can be used in accordance with the size of each user's foot, and therefore it is easy to perform a stepping exercise.

"Other embodiments"
As shown in FIG. 14, the rail a (19) has cuts at equal intervals on the side wall, so that the triangular portion (25) can be easily separated. There is also a protruding portion (26) from the bottom surface. Even when the floor is inclined by these, the effect of using the footrest (23) of the present invention can be obtained.

  For example, when the floor surface is inclined in the direction in which the rail a (19) extends long, the triangular portion (25) is cut along the cut. This can be easily separated. And rail a (19) can be bent and rail a (19) can be fixed along a floor surface. This state is shown in FIG.

  Further, when the floor surface is inclined in a direction perpendicular to the direction in which the rail a (19) extends long, as shown in FIG. 21, the rail a (19) is provided on the protruding portion (26) from the bottom surface. The rail a (19) can be fixed horizontally by adjusting the inclination of the bottom surface using the jack b (28) in the hole l (27). The type, size, or number of jacks b (28) may be changed as appropriate.

  For other floor surface inclinations, the rail a (19) is bent and the bottom surface inclination is determined by using the jack b (28) in the hole l (27) provided in the projecting portion (26) from the bottom surface. This can be dealt with by adjusting.

  The rail a (19) may be cut according to the shape of the installation floor. For example, in order to cut one side of the projecting portion (26) from the bottom surface, or to cut and shorten the rail a (19), or to increase the angle at which the rail a (19) bends, a triangular-shaped portion ( 25) Increase the notch at 25).

  Instead of the rail a (19), a rail b (29) whose shape is determined from the beginning according to the shape of the floor may be used. That is, the bottom surface of the rail a (19) shown in FIG. 14 is enlarged in accordance with the shape of the floor surface. This is shown in FIG. The material, shape or size of the rail a (19) and the rail b (29) may be appropriately changed.

  In the footrest (23) of the present invention, the hinged spring (3) which is an elastic body is provided only on the fulcrum side of the foot pedal, but in addition to this, the elastic body is provided on the opposite side of the fulcrum. Also good. Further, the fulcrum side of the foot pedal may be a free hinge (30) instead of the spring hinge (3), and an elastic body may be interposed on the opposite side of the fulcrum.

  In addition to the hinged hinge (3) on the fulcrum side of the foot pedal, it will be described that an elastic body is provided on the side opposite to the fulcrum. FIG. 23 shows a case where the spring b (31) is interposed. The spring b (31) has an intermediate diameter smaller than that of the upper end and the lower end. With such a shape, it is possible to smoothly expand and contract by drawing an arc.

  In addition, a spring c (32) having a shape other than the spring b (31), an oil damper, an air cushion, urethane, or the like may be added. In that case, if a support base is required, you may install in a pedal lower board (5). Here, the support base is not for expanding and contracting the elastic body so as to draw an arc like the spring b (31), but for expanding and contracting vertically and sufficiently exerting the drag of the interposed elastic body. .

  The fulcrum side of the foot pedal is set to a free hinge (30), and an elastic body is interposed on the opposite side of the fulcrum. As the elastic body, a spring b (31) or a spring c (32), an oil damper, an air cushion, urethane, or the like may be used.

  At that time, the support is provided if necessary. FIG. 24 shows a case through the spring c (32). The strength, shape or size of the hinge with spring (3) may be changed as appropriate. The shape or size of the free hinge (30) may be changed as appropriate. The strength, shape, size, or number of the interposed elastic body may be appropriately changed.

  The material of the pedal upper plate (1), the pedal lower plate (5), or the stopper a (8) may be appropriately made of a material having negative ion or far-infrared effect, resin, wood, plastic, or metal. .

  The shape or size of the pedal upper plate (1), the pedal lower plate (5), or the stopper a (8) may be appropriately changed. For example, the overall shape may be changed, or a hole may be made to reduce the weight. FIG. 25 shows an example in which the shape of the pedal upper plate (1) is changed. In addition, the pedal upper plate (1) or the stopper a (8) may be provided with a projection for stimulating the acupuncture points on the sole. Helps alleviate blood circulation.

  You may change suitably the kind or magnitude | size of junkie a (18). The pedal lower plate (5) may be directly attached to the rail a (19) with screws without using the jack a (18), or four jacks a (18) may be used on the front and rear as shown in FIG. good.

  This makes it possible to adjust the height in addition to the position or angle of the footrest of the present invention. Further, when the footrest of the present invention is installed at a position where the leg cannot be put out straight from the trunk, there is an effect of reducing the burden on the ankle.

  For example, if it must be installed diagonally to the left with respect to the torso, if the angle or height of the foot pedal is the same as when installed in front of the standard, the inside of the left ankle will be over-pressed when depressed. Being painful. In such a case, if the height of each of the four jacks a (18) is adjusted and the foot pedal can be tilted toward the trunk side, the burden on the ankle can be reduced.

  On the other hand, even when the leg can be straightened and installed in front of the torso, being able to adjust the angle or height reduces the burden on the ankle of a person with X or O legs.

  The pedal lower plate (5) may be directly attached to the rail b (29) shown in FIG. 22 without using the jack a (18). Moreover, you may attach a pedal lower board (5) using the jack a (18).

  Instead of the rail a (19), the rail b (29), the jack a (18), or the jack b (28), an electrically adjustable rail or jack may be used. You may change suitably the magnitude | size of the whole footrest (23) of this invention.

  The material, shape or size of the stopper b (15) may be changed as appropriate. For example, if it is made of rubber, the pedal upper plate (1) is stepped on, and the impact sound when it hits the stopper b (15) is reduced, so that it does not feel relatively bothersome.

  The foot pedal can be closed with a hook (33). This is convenient because only the foot pedal can be carried and the leg muscles can be moved appropriately.
