Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a standing vehicle such as a golf car.
[0002]
[Prior art]
A vertical riding vehicle such as a golf car has a steering shaft that is erected obliquely upward toward the rear of the vehicle body at the front portion of the vehicle body, and a step portion for a rider to stand on is provided at the rear portion of the vehicle body. Is constructed by laying an elastic member on a step substrate (see, for example, Japanese Patent Laid-Open No. 5-123429).
[0003]
[Problems to be solved by the invention]
By the way, in such a stand-up type vehicle, when the occupant stands on the step part, the weight is more heavily applied to the heel part than the toe part of the occupant's foot, but the conventional step part structure is elastic. Since the elasticity (spring constant) of the member was uniform over the entire area, the amount of bending of the elastic member where the heel portion of the occupant's foot hits was more forward than that (the foot ahead of the heel portion). It was larger than the amount of deflection of the part hitting the back part). For this reason, the toes of the occupant are higher at the toes than at the heel part, and there is a problem that the occupant cannot take a comfortable posture although the posture of the occupant becomes unnatural.
[0004]
Accordingly, an object of the present invention is to provide a standing type vehicle in which an occupant can ride in an easy posture.
[0005]
In addition, in order to make the longitudinal length of the vehicle compact, the longitudinal length of the step board of the step portion is set as short as possible, so that the occupant's heel part is on the rear edge where the elastic member of the step board does not exist In such a case, the impact from the road surface is not absorbed by the elastic member and is transmitted to the occupant as it is.
[0006]
Accordingly, the object of the present invention is to provide a vertical riding four-wheel vehicle that can always ensure a good riding feeling.
[0007]
[Means for Solving the Problems]
To achieve the above object, a first aspect of the present invention, comprising a step portion for passenger to ride up consisting configured laying an elastic member on a step substrate provided on the vehicle body rear portion Tatsuno In the type vehicle, the elastic member is composed of a main elastic member and a sub-elastic member having a larger spring constant than the main elastic member, the rear end portion of the elastic member is composed of the sub-elastic member, and the sub-elasticity of the elastic member The front side of the member is constituted by the main elastic member .
[0008]
According to a second aspect of the present invention, in the first aspect of the present invention, the sub elastic member is extended to the rear end edge of the step substrate and fixed on the step substrate, and the sub elastic member and the main elastic member are fixed. The upper surface of the elastic member is covered with a cover plate made of an elastic material.
[0009]
Therefore, according to the first aspect of the present invention, since the heel portion of the occupant's foot is received by the secondary elastic member having a larger spring constant than the main elastic member, the bending amount (sinking amount) of the heel portion is larger than that. Compared to the front portion, the heel portion of the occupant is not lowered below the toe portion, and as a result, the occupant can maintain a comfortable driving posture.
[0010]
According to the second aspect of the present invention, since the auxiliary elastic member is extended to the rear edge of the step board and fixed on the step board, the front and rear length of the step board is shortened for the purpose of compacting the front and rear length of the vehicle. Even if the occupant's heel part is located on the rear edge of the step board, the impact from the road surface is absorbed by the secondary elastic member, so that no strong impact is applied to the occupant's heel part. Always gives a good ride.

The golf car 1 is driven by standing and operating the bar handle 34 with both hands. Details of the configuration of the step unit 52 will be described with reference to FIGS. 10 to 12. 10 is a plan view of the step portion at the rear of the golf car, FIG. 11 is a sectional view taken along the line CC in FIG. 10, and FIG. 12 is a sectional view taken along the line DD in FIG.
[0034]
As shown in FIG. 11, channel-like cross members 53, 54, and 55 are laid between the rear portions of the pair of left and right main frames 2a of the vehicle body frame 2 at appropriate intervals in the front-rear direction, and the rearmost cross member. A plate-like step board 56 is installed behind 55 in an obliquely upwardly inclined manner toward the rear. A stopper portion 56a bent upward is formed at the rear end of the step substrate 56.
[0035]
Thus, another thin plate-like step substrate 57 is placed on the cross members 53 to 55, and the front end portion of the step substrate 57 is attached to the foremost cross member 53 by a plurality of rivets 58. ing. Further, a sheet metal stopper member 59 bent in a cross-section Z shape is welded to a position in front of the cross member 54 on the step substrate 57, and a sponge-like member is formed on the step substrates 56 and 57. The main elastic member 60 is laid so that the front end surface thereof is in contact with the stopper member 59.
[0036]
The rear portion of the main elastic member 60 extends to the front half of the step substrate 56, and the sub elastic member 61 divided into three parts is attached to the rear half of the step substrate 56 by a plurality of rivets 62. .
[0037]
Here, as shown in FIG. 12, each of the sub elastic members 61 is configured by integrally projecting two hollow projections 61b on a plate-like flange portion 61a at an appropriate interval, and the flange portion 61a. As described above, the rear end surface of the step substrate 56 is in contact with the stopper portion 56 a formed at the rear end portion of the step substrate 56 by the three rivets 62 inserted through the step substrate 56. . The spring constant when the secondary elastic member 61 is bent in the vertical direction is set larger than that of the main elastic member 60.
[0038]
Thus, the main elastic member 60 and the sub-elastic member 61 are laid on the step substrates 56 and 57. The main elastic member 60 and the sub-elastic member 61 are covered with a cover plate 63 made of hard rubber. The rear end of the cover plate 63 is attached to the auxiliary elastic member 61 by a plurality of rivets 65 via a sheet metal fixing member 64. That is, as shown in FIG. 11, a fixing member 64 having a U-shaped cross section is fitted into the rear end portion of the cover plate 63, and as shown in FIG. Is attached to the upper surface of each projection 61b of the secondary elastic member 61 by a plurality of rivets 65 via a fixing member 64.
[0039]
In the step portion 52 having the above-described configuration, when the occupant stands on the step portion 52, the occupant's feet (shoes) indicated by chain lines in FIGS. 10 and 11 are placed on the cover plate 63. At this time, the heel portion of the occupant's foot is positioned on the secondary elastic member 61, and the sole portion in front of the heel portion is positioned on the main elastic member 60.
[0040]
By the way, the weight is applied to the heel portion of the step portion 52 more than the toe portion of the occupant's foot (shoes), but in this embodiment, the heel portion of the occupant's feet (shoes) is more than the main elastic member 60. Since it is received by the secondary elastic member 61 having a large spring constant, the bending amount (sinking amount) of the heel portion is suppressed smaller than that of the toe portion, and the heel portion of the occupant's foot (shoes) is the toe portion. Therefore, the occupant can maintain a comfortable driving posture.
[0041]
In the present embodiment, since the auxiliary elastic member 61 is extended to the rear edge of the step board 56 and fixed on the step board 56, the front and rear sides of the step boards 56 and 57 are made compact in order to reduce the longitudinal length of the vehicle. Even when the occupant's heel portion is positioned on the rear edge of the step board 56 because the length is shortened, the impact from the road surface is also absorbed by the secondary elastic member 61 and a strong impact is applied to the occupant's heel portion. The rider is always given a good ride feeling.
[0042]
Further, a highly rigid metal fixing member 64 is fitted into the rear end portion of the cover plate 63 made of an elastic material, and the rear end portion of the cover plate 63 is fixed to the secondary elastic member 61 by the rivet 65 via the fixing member 64. Therefore, local deformation of the cover plate 63 is prevented and the cover plate 63 is deformed uniformly, and this also provides a good ride feeling.
[0043]
In the present embodiment, the case where the present invention is applied to a golf car has been described. However, the present invention can be applied to any other standing type vehicle.
[0044]
【The invention's effect】
As is clear from the above description, the heel portion of the occupant's foot is received by the secondary elastic member having a larger spring constant than the main elastic member. As a result, the heel portion of the occupant's foot is not lowered below the toe portion, and as a result, the occupant can maintain an easy driving posture.
[0045]
According to the second aspect of the present invention, since the auxiliary elastic member is extended to the rear edge of the step board and fixed on the step board, the front and rear length of the step board is shortened for the purpose of compacting the front and rear length of the vehicle. Even if the occupant's heel part is located on the rear edge of the step board, the impact from the road surface is absorbed by the secondary elastic member, so that no strong impact is applied to the occupant's heel part. Can always provide a good ride feeling.
