Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a low lift handle device.

[0002]

[Prior art]

 The low lift 20 is shown in FIG. The low lift 20 includes a main body portion 25, a handle post 5 pivotally attached to the main body portion 25, a handle device 21 mounted on the upper portion of the handle post 5, and a driver that can be steered by a turning operation of the handle device 21. It is composed of an Eve wheel 24, a movable portion 26 that is vertically movable with respect to the main body portion 25, and a fork 22 that is fixed to the tip of the movable portion 26. A caster 23 is mounted on the tip of the fork 22, and the caster 23 is mounted so as to be able to move up and down by a cylinder and a link mechanism (both not shown) housed in the main body 25. It is a well-known configuration.

FIG. 3 shows details of the handle device 21. In the figure, a guard plate 30 is fixed to the handle post 5, and a pivot 31 is fixed to a standing portion 30A formed on both left and right sides of the guard plate 30 with a screw 37 via a pad 36. Supported. The guard plate 30 and the standing portion 30A play a role of protecting the driver's hand even when the handle device 21 is brought into contact with a wall or some obstacle when the driver holds the grip portion 32. Is responsible for. Therefore, it is formed using an iron plate having a relatively thick wall thickness so as to improve its strength.

A grip portion 32 is rotatably supported on the pivot shaft 31 via a bearing 39 on the end portion side of the pivot shaft 31, and the grip portion 32 is supported by a snap ring 38. Directional movement is restricted.

The accelerator lever 33 is rotatably inserted into the pivot shaft 31 and fixed to a sleeve 35 having a substantially “D” -shaped cross section with a set screw 34. Therefore, when the accelerator lever 33 is rotated, the sleeve 35 is rotated with respect to the pivot 31.

A cam 8 that can rotate integrally with the sleeve 35 is fitted and mounted on the sleeve 35. As shown in FIG. 4 which is a BB view in FIG. The limit switch LS is configured to actuate forward / backward traveling commands by turning. In addition, 6 is a collar interposed between the handle post 5 and the sleeve 35, 9 is an emergency switch 9 elastically supported by the handle post 5 via a spring 10, and allows the driver to move between the wall and the low lift 20. The emergency switch 9 is actuated when it is sandwiched between and to stop the low lift 20 in an emergency.

[0007]

[Problems to be solved by the device]

 However, in the conventional configuration as described above, the rigidity of the guard plate 30 and the pivot 31 must be designed to be considerably high, which leads to the high cost of the device, and the number of steps for assembling the device. There is a problem of cost. The present invention has been devised in view of the above problems, and its purpose is to provide a low lift that can protect the driver's hand as in the conventional case and can greatly simplify the structure and improve workability during assembly. To provide a handle device.

[0008]

[Means for Solving the Problems]

 According to the present invention, an accelerator grip is fitted and mounted on both left and right sides of a pivot that is rotatably supported by a handle post, and a disk-shaped bulge radially bulged at the outer end of the accelerator grip. The above-mentioned problems are solved by adopting a structure in which a part is formed.

[0009]

【Example】

 The first embodiment of the present invention will be described below with reference to FIGS. 1 and 2, and the same components as those of the conventional device will be designated by the same reference numerals.

The handle device 1 of the present invention is configured to rotatably support a pivot shaft 3 via a collar 6 on a handle post 5 and insert and mount an accelerator grip 2 at both ends of the pivot shaft 3.

The accelerator grip 2 includes a grip portion 2A, which is a portion directly gripped by a driver, and a bulge portion 2B formed at an outer end of the grip portion 2A. The bulging portion 2B has a disk shape bulging in the radial direction, and the side end surface of the bulging portion 2B is fixed by screwing a screw 4 into the pivot 3.

Further, as shown in FIG. 2, the cross section of the pivot 3 has a substantially “D” shape, and the inner diameter of the accelerator grip 2 is also formed so as to correspond thereto. Therefore, when the accelerator grip 2 is rotated, the accelerator grip 2 and the pivot 3 are integrally rotated.

Retaining rings 7 are mounted on the left and right sides of the pivot 3 and at a predetermined distance from the handle post 5, and together with the flange portion 6A of the collar 6, the pivot 3 is moved from the handle post 5 to the pivot post 3. It is possible to prevent a large protrusion and an imbalance between the left and right protrusion amounts.

A cam 8 is fitted and mounted on the pivot 3 in the same manner as in the conventional art. Therefore, when the accelerator grip 2 is rotated, the pivot 3 and the cam 8 are also rotated integrally. A limit switch (not shown) can be activated.

[0015]

[Action]

 As shown in FIG. 6, the outside end surface of the bulging portion 2B can protect the hand of the driver against obstacles in the X direction, and the bulging portion 2B can be protected from the circumferential portion in the Y direction. This makes it possible to protect the driver's hand.

[0016]

As a result of adopting the above-mentioned configuration, the present invention reduces the number of parts without sacrificing the function of protecting the driver's hand as in the conventional case, and also greatly simplifies the structure and makes it easier to assemble. There is a practical effect that the workability of can be improved.
