Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator lever structure for an electric cart having a pair of left and right handle grips on a steering handle and an accelerator lever that can be operated by a grip operation with one of the handle grips.

[0002]

2. Description of the Related Art Conventionally, as an accelerator lever structure of this type of electric cart, for example, as disclosed in Japanese Patent Application Laid-Open No. 7-10061, a pair of left and right accelerator levers are manually gripped. In the structure in which the grasping lever portion and the crank-shaped supporting arm portion are integrally formed, the supporting arm portion is swingably supported by the steering wheel.

[0003]

Therefore, in the above-mentioned conventional structure, since the pair of left and right grasp lever portions and the support arm portion are integrally formed, the fingers of the left and right hands are paired with each other. It was supposed to be hung on each grasping lever part, but for example, when grasping the right grasping lever part, the grasping lever part on the left side also swings, so it is not operated. Therefore, holding the handle grip might become unstable. Therefore,
It is conceivable to provide the grasping lever part only on either the right side or the left side.However, there are cases where a person who cannot use the left hand or a right-handed operator operates, and when a person who cannot use the right hand or a left-handed operator operates. Therefore, it is necessary to be able to change the position where the accelerator lever is gripped to the left and right. However, when the left and right of the crank-shaped support arm is changed, the gripping part of the grasping lever part will be reversed in the front-back direction, so that the gripping force is detected by the pressure-sensitive sensor provided in the grasping lever part. In this case, the pressure sensor has to be installed at the gripping portion of the grasping lever on both front and rear sides, which is disadvantageous in that the cost is increased.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an accelerator lever structure of an electric cart capable of easily changing the accelerator operation position according to the dominant arm of the operator.

[0005]

(Structure) An accelerator lever structure for an electric cart according to claim 1 of the present invention is provided with a pair of left and right handle grips on a steering handle, and can be gripped together with one of the handle grips. An accelerator lever structure for an electric cart having an accelerator lever that can be operated by an accelerator, and a crank-shaped arm member configured to be detachable from a support member provided on the steering handle and to be able to change its mounting direction to the left and right. The accelerator lever is constituted by a grasping lever portion which is detachably attached to one end portion of the arm member and whose attachment direction can be changed rightward and leftward.

(Operation) According to the structure of claim 1 of the present invention, the accelerator lever is a crank-shaped member which is detachably attached to the support member provided on the steering handle and whose mounting direction can be changed to the left and right. Since it is composed of an arm member and a grasping lever portion which is detachably attached to one end portion of the arm member and whose mounting direction can be changed to the left and right, the one provided for a right-handed accelerator lever is provided. When changing to left-handed and vice versa, it can be configured as a single component for right-handed and left-handed, and by replacing it, it can be grasped as an accelerator lever on either side Become.

(Effect) Therefore, according to the structure of claim 1 of the present invention, the mounting direction of the arm member to the support member is simply changed, and the mounting direction of the grasping lever portion to the arm member is changed. You can get a right-handed or left-handed accelerator lever by simply attaching and detaching each, and you do not have to prepare both a right-handed and a left-handed grip lever part of the accelerator lever, so the number of parts is also The number can be reduced, and the cost can be reduced.

(Structure) The accelerator lever structure of the electric cart according to claim 2 of the present invention is the one according to claim 1, wherein the grasping lever portion has a feeling of detecting a pressure due to squeezing with the handle grip. A characteristic configuration is that a pressure sensor is provided.

(Operation) According to the configuration of claim 2 of the present invention, in the grasping lever portion provided with a pressure-sensitive sensor for detecting the pressure due to squeezing with the handle grip, By only providing the surface on which the pressure sensor is provided on one surface in the front-rear direction, a single grasping lever portion can be configured for both the right side and the left side.

(Effect) Therefore, according to the structure according to claim 2 of the present invention, the detection structure is extremely simple as compared with the accelerator operation structure of the mode for detecting the swing amount of the accelerator lever, and the mechanical structure is mechanical. It has excellent durability because it does not have such a structure, and as explained in the above operation, it has a simple structure in which the pressure-sensitive sensor is provided only on one surface of the grasping lever portion that is grasped by hand, The cost can be reduced because it is possible to replace the left-handed person.
