  The Saya Fork according to the first embodiment of the present invention will be specifically described with reference to the drawings as follows.

  FIG. 1 is a perspective view showing a Saya fork, FIG. 2 is a longitudinal side view thereof, FIG. 3 is a front view thereof, and FIG. 4 is a side view of a forklift equipped with the Saya fork.

  The forklift shown in FIG. 4 is a counterbalance forklift that travels with left and right drive wheels 2 supported on the front portion of the vehicle body 1 and steering wheels 3 supported on the rear portion of the vehicle body 1. Further, a lower end portion of an extendable mast 4 is supported at the front portion of the vehicle body 1 so as to be tiltable, and the mast 4 is tilted by left and right tilt cylinders 5. Further, a lift bracket 6 is supported on the mast 4 so as to be movable up and down, and a finger bar 7 and left and right forks 8 are supported on the lift bracket 6, and the lift bracket 6, finger bar 7, and left and right forks are supported by a lift drive device 9. 8 are raised and lowered along the mast 4 respectively.

  Saya forks 10 are respectively attached to the left and right forks 8, and as shown in FIGS. 1 to 3, the fork 10 includes a plate member 11 placed on the upper surface of the fork 8, The friction member 12 is formed of a rubber plate adhered to the upper surface of the plate member 11, left and right side stoppers 13, and a rear stopper 14.

  The plate member 11 may be formed of a highly rigid synthetic resin, but is formed of an iron plate in consideration of cost, strength, surface hardness, workability, and the like.

  The plate member 11 has a width slightly larger than the width of the fork 8 of the forklift, and the length thereof is set to an appropriate length according to the depth of the pallet supported by the fork 8. In the example of this embodiment, the length is set slightly shorter than the fork 8.

  The side stoppers 13 are extended and formed by bending both side edges in the width direction of the plate member 11 continuously and uniformly downward along the entire length thereof, and the respective inner surfaces thereof are side surfaces of the fork 8. Abut. The side stopper 13 is for preventing the Saya fork from moving left and right on the fork, and is thus set to have a vertical length equal to the vertical thickness of the horizontal portion 8a of the fork 8.

  The plate-like rear stopper 14 is fixed to one end of the both side stoppers 13. The rear stopper 14 is substantially U-shaped when viewed from above, and a fork insertion hole 15 through which the fork 8 is inserted is formed between the rear stopper 14 and the plate member 11.

  The rear stopper 14 allows the fork 8 to be smoothly inserted into the fork insertion hole 15, and in the mounted state shown in FIG. 1, the rear stopper 14 is a base end portion of the vertical portion 8 b of the fork 8, that is, a bent portion. It is formed at a position where it abuts on the rear surface or approaches as much as possible. As shown in FIG. 2, in this embodiment, in order to make the rear stopper 14 as close as possible to the vertical portion 8b, an arc shape is formed along the arc shape formed at the base end portion of the vertical portion 8b. It is bent. Further, the rear stopper 14 is formed such that the lower end thereof is positioned close to the lower surface of the fork 8 in a side view. The rear stopper 14 is formed of an iron plate in the same manner as the plate member 11 and the side stopper 13 described above.

  The structure of the Saya fork 10 is as described above. Therefore, the Saya fork 10 does not have a member below the plate member 11, and as shown in FIG. Arranged and side stoppers 13 are arranged on both sides thereof, and the entire lower part of the plate member 11 has a gate-like shape with an open space A.

  The saf fork 10 is attached to the fork 8 in the manner shown in the side view of FIG.

  First, the fork 8 is positioned at an appropriate height from the ground, and as shown by a two-dot chain line in FIG. 5, the plate member 11 is placed at the tip of the fork 8 with the sheath fork 10 and the rear stopper 14 facing down. The fork 8 is maintained in an inclined posture toward the vertical portion 8b. Thereafter, the Saya fork 10 is maintained in the same posture, and the horizontal portion 8a of the fork 8 is inserted into the fork insertion hole 15 so that the plate member 11 is attached to the vertical portion 8b of the fork 8 as shown by a one-dot chain line in FIG. The plate member 11 is placed on the horizontal portion 8 a of the fork 8 by horizontally moving the contactor fork 10 to the abutting position and then turning the whole of the sheath fork 10.

  As a result, the left and right side stoppers 13 of the Saya fork 10 abut against both side surfaces of the fork 8 in the width direction, and the Saya fork 10 is positioned in the width direction of the fork 8. Further, the rear stopper 14 is positioned on the rear surface of the base end portion 8c of the fork 8 and is received by the rear surface, so that the front fork 10 is prevented from being detached from the fork 8 forward. Of course, the separation of the Saya fork 10 toward the rear of the fork is prevented by the plate member 11 coming into contact with the vertical portion 8 b of the fork 8.

  By attaching the Saya fork 10 to the fork 8 in this way, the friction material 12 is disposed on the horizontal portion 8a of the fork 8, and slipping of the pallet supported via the friction material 12 can be prevented. It becomes like this. Further, the Saya fork 10 can be separated from the fork 8 easily and in a short time by the reverse procedure.

  Since the entire lower area of the Saya fork 10 is widely opened due to the presence of the open space A, the Saya fork 10 can be attached to the fork 8 from above, and the Saya fork 10 is shorter than the fork 8. Even if it is set, there is no problem in wearing. In this case, the Saya fork 10 covers the upper surface of the fork 8 leaving the fork tip side portion.

  Further, when the friction material 12 is worn due to contact with a load, it can be restored to a state in which the friction material 12 is not worn by exchanging the friction material 12 with a new one, which is very convenient.

  FIG. 6 shows a Saya fork 10 according to the second embodiment of the present invention.

  In this embodiment, the rear stopper 14 is formed in a substantially L shape in a top view, and is fixed to the side stopper 13 so as to extend from the side stopper 13 at one end thereof. The fork insertion hole 15 formed between the rear stopper 14 and the plate member 11 is formed so that one end of the side portion is opened.

  In the Saya Fork 10 according to the second embodiment, other configurations are the same as those of the first embodiment described above.

  According to the second embodiment, the Saya Fork 10 can be attached to and detached from the fork 8 in the same manner as in the first embodiment, and the Saya Fork 10 can also be attached and detached from the width direction of the fork 8. it can.

  For example, as shown by a two-dot chain line in FIG. 6, first, the Saya fork 10 is positioned substantially parallel to the fork 8 so that the opening of the fork insertion hole 15 faces the base end portion 8 c of the fork 8. . Next, the Saya Fork 10 is moved to the fork 8 side in a state where the Saya Fork 10 is inclined so that the side stopper 13 on the opening side of the fork insertion hole 15 is higher than the upper surface of the horizontal portion 8a of the fork 8, and thereafter The plate member 11 is placed on the horizontal portion 8a of the fork 8 by turning the Saya fork 10 to a horizontal posture. When the Saya Fork 10 is detached from the fork 8, it is performed by the reverse method.

  In each of the above-described embodiments, the rear stopper 14 is fixed to the side stopper 13, but the rear stopper 14 may be formed to extend from the plate member 11. Of course, the side stopper 13 and the rear stopper 14 do not always have to abut against the fork 8, and a force in the direction of separation acts so that the Saya fork 10 does not unexpectedly leave the fork 8. It may be anything that comes into contact with the fork 8 sometimes.

  Note that, as described above, the present invention involves the work of placing and mounting the plate member 11 on the fork 8 in the detaching work of the Saya fork 10, so that an open space A is formed below the plate member 11. There is a need.

  Further, in the present invention, the anti-slip plate-like friction material 12 made of rubber, resin or the like is attached to the upper surface of the plate member 11, or irregularities are formed on the upper surface of the plate member 11 to form the friction material 12. By using it, it is possible to effectively prevent the load from slipping off from the Saya Fork 10 and coming off.
