It is arranged. Such a vehicle operation device has a swingable operation lever and an operation knob formed at the tip of the operation lever. For example, an operator holds the operation knob while moving the operation lever back and forth or When it is swung left and right, the vehicle and equipment can be operated according to the rocking angle.

  However, in the conventional vehicular operating device as described above, the operating knob and the operating lever are not allowed to rotate around the axis (hereinafter referred to as Conventional Example 1), and there are almost no restrictions on the rotation around the axis. In some cases, the rotation was free (hereinafter referred to as Conventional Example 2). In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

However, the conventional vehicle operating device has the following problems.
When the operator swings the operating lever while holding the operating knob, in the conventional example 1, the operating knob and the operating lever do not rotate at all around the axis, so that the operating knob according to the swinging angle of the operating lever. In the conventional example 2, there is a case where the operator rotates carelessly about an axis that is not intended by the operator. In any case, the operability is poor. there were.

  The present invention has been made in view of such circumstances, and provides a vehicular operating device capable of improving the operability when the operator swings the operating lever while holding the operating knob. It is in.

According to the first aspect of the present invention, there is provided an operation knob that can be gripped by an operator, a support portion fixed to the vehicle side, and an operation lever that is swingably supported by the support portion while extending from the operation knob. A vehicle operating device for performing a predetermined operation on the vehicle or equipment included in the vehicle in accordance with a swing angle about the support portion of the operating lever. while permitting its rotation angle with the rotation regulating means for regulating within a predetermined range Rutotomoni, said rotation restricting means is protruded from the operation lever, a convex shape that rotates with the rotation of the operation lever A member, and a notch portion that is formed in the support portion and restricts the rotation angle within a predetermined range while allowing the convex member to rotate, and the supported portion of the operation lever is The substantially arc shape formed in the support part The operation lever can be swung back and forth, right and left, and obliquely, and the convex member can swing the operation lever in a predetermined direction at the supported portion. It is located on the moving axis .

According to a second aspect of the invention, in the vehicular operating apparatus according to claim 1 Symbol mounting, the rotation restricting means includes a feature to be restricted to a range of left and right rotation axes substantially 5 ° increments of the operating lever To do.

  According to the first aspect of the invention, the rotation restriction means allows the rotation of the operation lever around the axis and restricts the rotation angle within a predetermined range, so that the operator holds the operation knob while holding the operation knob. The operability when swinging can be improved.

In addition , since the rotation of the convex member is restricted within a predetermined range by the notch portion of the support portion, the rotation around the axis of the operation lever is restricted within an angle within the predetermined range, so that the configuration is relatively simple. The operability when swinging the operation lever can be improved.

Further , the operating lever can be swung back and forth, right and left, and obliquely, and the convex member is located on the swinging shaft of the operating lever in a predetermined direction in the supported portion. The movement of the shaped member can be minimized, and the structure of the support portion can be further simplified.

According to the invention of claim 2 , the rotation restricting means restricts the rotation around the axis of the operation lever within a range of approximately 5 ° on each of the left and right sides. Rotation around can be performed.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The vehicle operating device according to the present embodiment is disposed on a construction machine such as a forklift and can operate, for example, a fork. As shown in FIGS. 1 to 3, an operation in which a push button 6 is formed on the top. Knob 1, operation lever 2 extending downward from the operation knob 1, a support portion 3 that supports the operation lever 2 so as to be swingable, and an operation that is provided on the vehicle side and includes the support portion 3. The apparatus main body 4 is mainly composed of a convex member 8 as a rotation restricting means and a notch 3a.

  The operation knob 1 can be gripped by an operator, and is fixed with an upper end side of an operation lever 2 formed of a hollow long member, and a bellows-like cover 5 is attached. The lower end of the cover 5 is fixed by being sandwiched between the mounting portion K of the vehicle, and covers between the operation knob 1 and the mounting portion K to prevent intrusion of rainwater, foreign matter, and the like. However, when the operation knob 1 is operated to swing the operation lever 2, the bellows expands and contracts following the operation lever 2, and the state of covering the space between the operation knob 1 and the mounting portion K is maintained. Yes.

  The operation lever 2 is supported by the support portion 3 so as to be swingable, and the supported portion 2a (the portion supported by the support portion 3) has a substantially spherical shape as shown in FIGS. The support surface 3b of the support portion 3 is formed in a substantially arc shape following the surface shape. As a result, when the operation knob 1 is operated, the surface of the supported portion 2a slides on the support surface 3b, and the operation lever 2 can be swung in the front-rear direction a and the left-right direction b. (Between and b) is also possible.

  On the other hand, the vicinity of the lower end of the operating lever 2 is connected to a pair of swinging members 9 and 10 that can swing within the operating device body 4. As shown in FIGS. 5 and 6, the swinging members 9 and 10 are respectively formed with elongated holes 9a and 10a extending in the central longitudinal direction, and arm portions 9b, 9c and 10b protruding from both ends, 10c is formed, and the arm portions 9b, 9c and 10b, 10c are supported in the operation device main body 4 so as to be swingable.

  In addition, a potentiometer 11 is connected to the arm portions 9b and 10b so that the rotation angle of the arm portions 9b and 10b can be detected. Thus, when the vicinity of the lower end of the operation lever 2 is inserted into both the long holes 9a and 10a (see FIG. 6) and the operation lever 2 is swung in the front-rear direction a, the left-right direction b, or the oblique direction, Since the swing members 9 and 10 swing in conjunction with each other and the rotation angle of the arm portions 9b and 10b is detected by the potentiometer 11, based on the detected value of the potentiometer 11 (ie, Depending on the swing angle of the control lever 2, the vehicle (forklift or the like) or the equipment (hawk or the like) provided in the vehicle is caused to perform a predetermined operation.

  A rod 7 whose upper end is connected to the push button 6 is disposed in a hollow portion extending in the axial direction of the operation lever 2. The lower end 7 a of the rod 7 is in contact with the upper surface of the receiving member 12 formed at the lower part of the operating device body 4. When the push button 6 is pressed, the receiving member 12 can be lowered via the rod 7. It is configured as follows. In addition, a magnet 12a is formed on a part of the receiving member 12, and when the receiving member 12 descends and the Hall IC 13 detects the magnetism from the magnet 12a, the pressing operation of the push button 6 is detected, A predetermined operation of the vehicle (operation different from the operation by the swing operation of the operation lever 2) is performed.

  Here, in this embodiment, the convex member 8 and the notch that restrict the rotation angle within a predetermined range while allowing the operation lever 2 to rotate about the axis L (rotation in the direction c in FIG. 4). 3a (rotation restricting means) is formed. The convex member 8 is composed of a pair of pin-like members formed to protrude laterally from the approximate center of the supported portion 2a of the operation lever 2, and the rotation of the operation lever 2 (with the axis L as the center as shown in FIG. 4). Rotation).

  The notch 3a is formed in a concave shape built in the support portion 3 (support surface 3b side), and is formed at a position corresponding to the convex member 8 as shown in FIG. The rotation angle of the convex member 8 accompanying the rotation around the axis L is restricted within a predetermined range. That is, the notch 3a is set so that the rotation angle of the convex member 8 can be restricted to a range of α ° on the left and right sides by interference with the convex member 8 whose side wall surface rotates. It is.

  Accordingly, the rotation angle of the operation lever 2 around the axis L is allowed and the rotation angle is restricted within a predetermined range (left and right α °), so that the operator can swing the operation lever 2 while holding the operation knob 1. In this case, it is possible to avoid problems caused by the operation lever 2 not rotating at all (requires re-grip) and problems caused by excessive rotation (such as inadvertent rotation). Can be improved.

  That is, even if the operator swings the operation knob 1 while gripping it firmly, the operation lever 2 rotates about the axis L together with the operation knob 1, so that re-gripping in the operation process is unnecessary, and Since the rotation is regulated within a predetermined range, the problem of excessive rotation is suppressed. In addition, at the time of manufacture of the support part 3, the rotation of the operation lever 2 around the axis L can be adjusted to a desired angle by arbitrarily changing the side wall position of the notch part 3a.

  Further, according to the present embodiment, the rotation of the convex member 8 is restricted within a predetermined range by the notch portion 3a of the support portion 3, so that the rotation of the operation lever 2 around the axis L is within a predetermined range of angle α. Therefore, it is possible to improve the operability when the operation lever 2 is swung with a relatively simple configuration. However, it is preferable to restrict the rotation of the operation lever 2 around the axis L to a range of approximately 5 ° on each of the left and right sides (that is, α is approximately 5 °). In this case, more appropriate from the viewpoint of improving operability. The operation lever 2 can be rotated around the axis L within the range.

  By the way, when the operating lever 2 is swung in the left-right direction b, as shown in FIG. 7, the convex member 8 moves up and down, so that it is notched to avoid interference with the moving convex member 8. Although the portion 3a is formed large in the vertical direction, when the operation lever 2 is swung in the front-rear direction a, as shown in FIG. 8, the convex member 8 is formed at the approximate center of the supported portion 2a. Since it is located on the rocking shaft, movement in the vertical direction is suppressed, and a shape for preventing interference is not necessary.

  On the other hand, when the convex member 8 is not substantially at the center of the supported portion 2a, the convex member 8 moves up and down when the operation lever 2 swings in all directions, and the interference is prevented. A separate shape is required. Therefore, according to this embodiment, since the convex member 8 is formed at the approximate center of the supported portion 2a, the movement of the convex member 8 when the operation lever 2 is swung can be minimized. The structure of the support part 3 can be further simplified.

  Although the present embodiment has been described above, the present invention is not limited to this, and while allowing rotation around the axis of the operating lever that can be swung only in either the front-rear direction or the left-right direction, You may comprise so that a rotation angle may be controlled in a predetermined range. The rotation restricting means for restricting the rotation angle within a predetermined range is not limited to that of the present embodiment, and other forms (providing a convex member from the support portion side and rotating the convex member on the supported portion side). For example, a notch that restricts movement may be provided.

  In the present embodiment, the swing members 9 and 10 are swung in accordance with the swing of the operation lever 2 and the operation direction and swing angle of the operation lever 2 can be detected. The operation direction and the swing angle may be detected with another configuration. Of course, the present invention can also be applied to the case where the operation knob 1 is not provided with the push button 6 as in the present embodiment, or the case where another operation means is formed.

While permitting rotation about the axis of the operating lever, Rutotomoni comprising a rotation restricting means for restricting the rotation angle within a predetermined range, the rotation restricting means is protruded from the operation lever, with rotation of the operating lever A convex member that rotates, and a notch that is formed in the support portion and restricts the rotation angle of the convex member within a predetermined range while allowing the convex member to rotate. The portion is formed in a substantially spherical shape that can slide on a substantially arc-shaped support surface formed in the support portion, and the operation lever can be swung back and forth, right and left, and obliquely, and the convex member is As long as the operating device for a vehicle is positioned on a swing axis in a predetermined direction of the operating lever in the support portion , the operating device can be applied to devices having different external shapes or those having other functions added.
