Description

The present invention relates to a footrest used for a seat of a vehicle such as an automobile, an aircraft, and a ship. More particularly, the present invention is a suspension used to reduce body fatigue, particularly leg and waist fatigue, when the user is forced to sit for a long time in a vehicle seat and the limited space around it. It relates to a vertical footrest.

A conventional footrest has a structure in which the footrest portion is placed on the floor surface, a structure in which the footrest portion is fixed to a seat or a frame, and a footrest portion is a belt or string (hereinafter referred to as “ It has been devised to suspend using a "band". The present invention improves the suspension type structure in which the footrest portion is suspended using a belt-like body so as to reduce the fatigue of the legs.

A conventional hanging type footrest has a structure in which a footrest is suspended using a belt-like body, and is attached to the upper end side of the belt-like body to hang the belt-like body on the front seat, A footrest that is attached to the lower end side of the body and puts the tip from the heel is provided (Patent Literature 1, Patent Literature 2).
).
JP-A-7-228179, FIG. JP-A-2002-23382, FIG. 1, FIG. 4, FIG.

The hanging type footrest described in the above publication is configured so that a comfortable posture can be maintained by changing the position of the foot by adjusting the length of the belt-like body. However, on the other hand, in order to make the height of the foot constant, all of the belt-like bodies of the conventional footrest are non-stretchable. When a non-stretchable belt-like body is employed, the movement of the foot in the vertical direction is restricted. If the same posture is forced in the vehicle for a long time, there is a problem that blood circulation of the foot becomes worse like so-called economy syndrome.

In addition, any vehicle such as an automobile, an aircraft, and a ship generates vibration and shaking. As long as a non-stretchable belt-like body is employed as in a conventional footrest, vibrations in the up and down direction and vibrations cannot be absorbed even if the vibrations in the front and rear and the right and left can be absorbed. For example, in the case of an automobile, road surface unevenness causes vibrations in the vertical direction to act on the waist through the vehicle body and on the heel through the footrest. However, since the thighs, knees, and inflated shins between the waist and the heel are not supported, there is a problem that the burden on the knees and the like due to vibration increases, and the effect of reducing fatigue cannot be obtained sufficiently. .

SUMMARY OF THE INVENTION An object of the present invention is to provide an improved suspended footrest used for reducing fatigue of legs and legs in a vehicle that is required to sit for a long time in a seat and a limited space around the seat. There is.

The present invention includes, firstly, a stretchable strip having flexibility, a fastener attached to an upper end side of the strip to suspend the strip from a structure, The said subject is solved by the footrest for vehicles comprised from the footrest part attached to the lower end side.

In the footrest of the first invention, for example, a belt-like body is hooked on a structure such as a front seat using a fastener. A footrest portion is attached to the lower end side of the belt-like body, and the position of the footrest portion is set by adjusting the length of the belt-like body so that a comfortable posture is obtained. When the tip is placed on the footrest part from the heel, the foot is in a floating state.
The belt-like body of the footrest according to the present invention has flexibility and stretchability, and allows the foot to move freely while allowing the foot to move freely. Further, when vibrations or shakings in the front / rear / left / right direction occur in the vehicle, the flexible belt-like body follows the vibrations in the front / rear / left / right direction and so on, so as to relieve vibrations acting on the foot. Further, when vertical vibrations or vibrations occur in the vehicle, the stretchable belt-like body absorbs vertical vibrations and so forth, so that vibrations acting on the foot are alleviated. As described above, the present invention reduces fatigue when the legs are in the same posture for a long time by the function of moving the foot in three dimensions of front and rear, left and right and up and down and the function of absorbing vibration in three dimensions of front and rear, right and left and up and down. can do.

Secondly, the present invention provides a non-stretchable strip having flexibility, a stretchable elastic body connected to the strip, and suspends the strip and the elastic body on a structure. Therefore, the above object is achieved by a vehicle footrest composed of a fastener attached to the upper end side of the belt-like body and the elastic body, and a footrest attached to the lower end side of the belt-like body and the elastic body. Resolve.

In the footrest device of the second invention, as in the first invention, the belt-like body is hooked on the front seat using the fastener, and the length of the belt-like body is adjusted to set the position of the footrest portion. . When the tip is placed on the footrest part from the heel, the foot is in a floating state.
The belt-like body of the footrest of the present invention is flexible but non-stretchable. A stretchable elastic body is connected to a non-stretchable strip. The belt-like body and the elastic body have flexibility and stretchability as a whole, allowing the foot to move freely and allowing the foot to move naturally. The elastic elastic body absorbs vibrations acting on the foot by absorbing vibrations in the vertical direction. As described above, the present invention reduces fatigue when the legs are in the same posture for a long time by the function of moving the foot in three dimensions of front and rear, left and right and up and down and the function of absorbing vibration in three dimensions of front and rear, right and left and up and down. can do.

Thirdly, the present invention provides a non-stretchable strip having flexibility, a stretchable elastic body that loosens an intermediate portion of the strip and short-circuits, and the strip is suspended from a structure. Therefore, the above-mentioned problem is solved by a vehicle-mounted footrest composed of a fastener attached to the upper end side of the belt-like body and a footrest attached to the lower end side of the belt-like body.

In the footrest device of the third invention, as in the first invention, the belt-like body is hooked on the front seat using the fastener, and the length of the belt-like body is adjusted to set the position of the footrest portion. . When the tip is placed on the footrest part from the heel, the foot is in a floating state.
The belt-like body of the footrest of the present invention has flexibility but is not stretchable. The non-stretchable belt-like body is short-circuited by loosening the non-stretchable belt-like body and using a stretchable elastic body like a bridge. The non-stretchable belt-like body short-circuited at the middle part by the elastic body has flexibility and stretchability as a whole, and allows the foot to move freely while allowing the foot to move freely. In addition, the elastic elastic body absorbs vibrations acting on the foot by absorbing vertical vibrations and the like. As described above, in the present invention, the function of moving the foot in the front / rear / right / left and up / down three dimensions and the function of absorbing the vibration in the front / rear / left / right and up / down three dimensions reduce fatigue when the posture is the same for a long time. can do.
Furthermore, if you adjust the dimensions of the short circuit, the belt will be tensioned when the elastic body stretches beyond a certain level, so you can adjust the cushion function in the vertical direction and prevent the footrest part from touching the floor of the vehicle. It can also be set.

Moreover, it is comprised from a left-right paired footrest, and you may make it connect the footrest part of each footrest with a flexible string or belt.
In the first to third inventions, attention is paid to a footrest that is configured to place only one foot. However, when a pair of left and right footrests are used, it is comfortable that the left and right feet move freely. May be impaired. Therefore, the left and right feet can be moved together by connecting the left and right footrest portions with a flexible string or belt.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of use of a suspended footrest according to the first embodiment, FIG. 2 is an enlarged perspective view of a suspended footrest, and FIG. 3 is an enlarged perspective view of a footrest portion.

The suspended footrest 10 of the present embodiment includes a band 12, a fastener 14, and a footrest 16, and is configured to be used for a rear seat of an automobile.
The belt-like body 12 is a long rubber cord having flexibility and stretchability. In order to attach the suspended footrest 10 to the handle 20 of the front seat 18 or the bracket 24 of the headrest 22 as a structure, a fastener 14 is attached to the upper end side of the rubber cord 12. On the lower end side of the rubber cord 12, a footrest portion 16 for placing the tip from the heel of the foot is attached. Foot rest part 1
6 is a heel-like shape that fits the shape of the foot from the heel of one foot to the toe.
6 is suspended from the arch portion 28 on both sides.

If the rubber cord 12 is wound around the handle 20 or the metal fitting 24 while adjusting the length so that the foot does not touch the floor even if it is placed on the footrest portion 16, and the fastener 14 prevents the rubber cord 12 from being unwound, a predetermined amount is obtained. The footrest portion 16 is suspended from the height. At this time, a fastener 14 like a buckle
The rubber string 12 may not be unwound using In this embodiment, the suspended footrest 10 is suspended from the front seat, but the suspended footrest 10 may be suspended from an appropriate structure depending on the place and seat used.

When used for both the left and right feet, each hanging footrest 10 is attached to the structure. Each hanging footrest 10 need not be attached to the same structure, but in order to obtain a sense of security or to make it easier to balance, it is preferable that they are moved together rather than independently. . Therefore, the footrest portion 1 of the pair of left and right suspended footrests 10, 10
6 is provided so that the fastener receivers 30 and 30 face each other, and a flexible string or belt 3
2, the footrest portions 16, 16 are connected to each other.

As described above, the suspended footrest 10 is attached to the front seat, and the footrest is used while sitting on the rear seat and placing the foot on the footrest portion 16. By adjusting the length of the rubber strap 12, the footrest portion 16 is in a suspended state, and when the foot is placed on the footrest portion 16, the rubber cord 12 is extended by the weight of the foot. When the automobile is stationary, the rubber strap 12 hardly expands or contracts unless the user voluntarily moves his / her foot or body.

When the car is running, three-dimensional vibrations and vibrations act on the legs floating in the air due to starting and stopping, curves, and uneven road surfaces. The suspended footrest 10 absorbs vibrations and vibrations in a three-dimensional direction acting on the vehicle by the action of the rubber string 12.
By hanging the footrest portion 16 with a flexible rubber strap 12, the left and right feet independently move naturally. Further, the elastic cord 12 relieves an extra force acting on the foot by following vibrations and vibrations in the front and rear, right and left directions. When vertical vibration or shaking occurs, the elasticity of the rubber string 12 absorbs the vertical vibration and so on, so that the vibration acting on the foot is alleviated. As described above, the function of moving the foot in three dimensions and the function of absorbing vibration in the three dimensions enhance the blood flow of the legs by actively moving the legs without being restricted to a certain posture. Moreover, since vibration can be absorbed, fatigue when riding in the same posture for a long time can be reduced.

Further, as shown in the figure, the left and right feet can be moved together at a constant interval by connecting the left and right footrest portions with a flexible string or belt. By doing this,
This provides a sense of security and makes it easier to balance when riding.
