Description

  The present invention relates to a device for preventing a driver of a forklift from driving without a seat belt attached.

  The driver seat of the forklift is equipped with a two-point seat belt device, and the driver of the forklift is obliged to operate with a seat belt. However, since the belt storage portion for storing the seat belt of the seat belt device is attached to the side portion of the driver's seat, the belt storage portion is inconspicuous, and the driver may drive the forklift without noticing the seat belt device.

  In order to prevent this, every time a forklift is started, a warning message is displayed on the screen to “do seat belt” (see Patent Document 1), or an alarm sound is generated when the seat belt is not attached. (See Patent Document 2).

  However, in each of the above-described technologies, the driver can issue a warning for driving the forklift without wearing the seat belt, but further operations (for example, forcing the driver to seat belt) This is not a forced action. For this reason, the driver may ignore the warning and drive the forklift.

In addition, in each of the above-described techniques, the driver can recognize the presence of the seat belt, but the operation of the driver wearing the seat belt remains the same as the conventional one and does not facilitate the operation.

  In view of the above-described circumstances, an object of the present invention is to enable a driver of a forklift to reliably and easily attach a seat belt.

Means for Solving the Problems and Effects of the Invention

The present invention for solving the above problems is as follows.
A device for preventing a driver of a forklift from driving without a seat belt,
A seat belt that presses the trunk of the driver seated in the driver seat;
A belt storage unit that is attached to the left side of the driver's seat in a front view of the forklift and winds and stores the seat belt;
A first hook portion that is also attached to the right side and hooks a seat belt that is pulled out to press the torso of a driver seated in the driver's seat from the belt storage portion and locks the seat belt so that it cannot be wound;
A seat belt attached to the front of the driver's seat and pulled out from the belt storage portion so as to hang over a space formed above or around the handle of the forklift is locked to be unwound, and the driver's seat is locked. A second hook that makes it difficult for the driver seated in
It is characterized by having.

  The seat belt can be releasably connected to the second hook portion in a space portion directly above the handle.

  The seat belt non-mounting prevention device for a forklift according to the present invention is configured as described above, and is attached to the left side of the driver's seat in the front view of the forklift (the right side of the driver's seat in the traveling direction) in the non-operating state. The seat belt pulled out from the belt storage portion is hooked on a second hook portion attached to the front of the driver's seat, and is hung on the space above or around the handle. For this reason, the driver who got on the forklift can surely see the seat belt. When the driver gets on the right side of the driver's seat in the front view of the forklift (the left side of the driver's seat in the traveling direction), the driver can get on as it is without interfering with the seat belt. Further, since the seat belt has already been pulled out, it is not necessary for the driver seated in the driver's seat to pull out the seat belt from the belt storage portion.

  When the driver seated in the driver's seat tries to drive the forklift, the seat belt becomes an obstacle to driving, and the driver is forced to remove the seat belt from the second hooking portion. The seat belt removed from the second hooking portion is directly hooked on the first hooking portion attached to the right side of the driver's seat in the front view of the forklift (left side of the driver's seat in the traveling direction). Press the torso of the driver who is seated. That is, since the driver only needs to move the hand hung on the seat belt to the first hook as it is, the operation of mounting the seat belt is easy. Further, when the driver is about to get off from the driver's seat after finishing the operation of the forklift, the driver only has to hook the seat belt removed from the first hook portion on the second hook portion as it is.

The second hook is attached to the right front column in the front view of the forklift,
When the seat belt is hooked on the second hook portion, the seat belt can be disposed across the space between the driver's seat and the handle diagonally in plan view.

  As a result, the seat belt can be arranged so as not to hinder the driver's getting on and off and also to hinder driving. For this reason, the driver is forced to remove the seat belt, and the wearing rate of the seat belt is increased.

  The second hook portion is a hook portion main body wound in a reel shape, a hook piece provided at a front end portion of the hook portion main body and engaged with the seat belt, and the hook portion main body. And a case body that accommodates in a wound state with a predetermined winding force.

  When the seat belt is not hooked on the second hook portion, the hook portion main body of the second hook portion is accommodated in the case body with a winding force. For this reason, the second hook portion does not hinder the operation of the forklift.

  The seat belt engaged and connected to the second hook is preferably disposed so as not to obstruct a passage when a driver who sits in the driver's seat gets out of the driver's seat of the forklift.

  Thereby, when the driver gets on and off the forklift, the seat belt does not hinder.

  Further, a warning can be issued when the key switch of the forklift is off and the seat belt is not hooked on the second hooking portion.

  As a result, it is possible to reliably prevent the driver from driving the forklift with the seat belt not attached.

  Examples of the present invention will be described. FIG. 1 is a side view of a forklift 100 according to an embodiment of the present invention, FIG. 2 is a plan view of the same, and FIG. 3 is a plan view of an operation unit 5 of the forklift 100.

  First, the overall configuration of the forklift 100 will be described. As shown in FIG. 1 and FIG. 2, the forklift 100 includes a vehicle body 1 and a cargo handling device 2 that is mounted on the front portion thereof. A plurality of struts (two front struts 3a and two rear struts 3b in this embodiment) are erected on the body 1 of the forklift 100. A head guard 4 is laid on the upper ends of the columns 3a and 3b.

  In the vehicle body 1, a driving unit 5 is provided in a portion surrounded by the respective columns 3 a and 3 b and the head guard 4. A driver's seat 6 on which a driver (not shown) is seated is attached to the driver 5. A steering wheel 7 and a plurality of (four in this embodiment) operating levers 8 are attached to the front of the driver's seat 6 in the driving unit 5, and an accelerator pedal 9 and a brake are also provided on the floor. A pedal 10 is attached (see FIG. 3).

  The cargo handling device 2 includes a mast 11 attached to a front portion of the vehicle body 1 so as to be tiltable in a vertical plane, and two forks 12 attached to the mast 11 so as to be movable up and down. The tilting operation of the mast 11 and the raising / lowering operation of the fork 12 are performed by the operating lever 8 provided in the driving unit 5. In FIG. 1, 13 is a front wheel of the forklift 100, and 14 is a rear wheel.

  Next, the operation unit 5 of the forklift 100 will be described in detail with reference to FIG. Steps 15 and 16 are respectively provided in portions on both sides of the driving unit 5 that are one step lower than the floor on which the accelerator pedal 9 and the brake pedal 10 are attached. The driver of the forklift 100 gets into the driving unit 5 from either of the left and right steps 15 and 16 and sits on the driver's seat 6. The driver can get into the driving unit 5 from any of steps 15 and 16, but in a portion on the right side of the driving seat 6 in the traveling direction (a portion on the left side of the driving seat 6 in the front view of the forklift 100). Since the operation lever 8 is arranged and the passage is narrowed, the vehicle often gets in from the left step 15. In the following description, “right side of driver's seat” means “right side of driver's seat in traveling direction (in other words, left side of driver's seat in front view of forklift)”.

  The driving unit 5 of the forklift 100 is equipped with a seat belt device 200 (a seat belt non-mounting prevention device). The seat belt device 200 of the present embodiment is stored in the belt storage unit 17 installed on the right side of the driver's seat 6, the buckle 18 (first hook) installed on the left side, and the belt storage unit 17. The seat belt 19 is provided, and a hooking portion 22 (second hooking portion), which will be described later, is provided. The belt storage portion 17 is provided with a belt winding means (for example, a mainspring) (not shown), and the seat belt 19 is always wound and stored in the belt storage portion 17 by the winding force of the belt winding means. It is energized in the direction.

  A driver (not shown) seated in the driver's seat 6 pulls out the seat belt 19 from the belt storage portion 17 against the winding force of the belt winding means, and pulls the seat belt 19 that is pulled out to his / her body 21. The tongue 19a provided at the tip is engaged with the buckle 18. As a result, the seat belt 19 presses the driver's torso 21 against the driver's seat 6. As a result, the driver can accurately perform the forklift work.

  In the seat belt device 200 according to the present invention, a hook portion 22 (second hook portion) for hooking the tongue 19a of the seat belt 19 pulled out from the belt storage portion 17 to a portion other than the buckle 18 is attached. The hooking portion 22 of this embodiment includes a hooking portion main body 23 that is wound up in a reel shape, and a case body 24 that accommodates the hooking portion main body 23 in a wound state. Are attached directly below the mirror 25 in the front column 3a. The case body 24 is provided with a winding means (for example, a mainspring) that urges the hook portion main body 23 drawn from the case body 24 in the winding direction. A hook-like hook portion 23 a is provided at the front end portion of the hook portion main body 23, and the hook portion 23 a is hooked in the hole portion 20 of the tongue 19 a of the seat belt 19 pulled out from the belt storage portion 17. . Thereby, the seat belt 19 and the hook part main body 23 are connected. At this time, the seat belt 19 is urged in the winding direction by the urging force of the winding means provided in the belt storing portion 17, and the hook body 23 is urged by the urging force of the winding means provided in the case body 24. It is biased in the winding direction (the direction opposite to the winding direction of the seat belt 19). For this reason, the seat belt 19 and the hook portion main body 23 are arranged in a state of pulling each other with a constant tension.

  The operation of the seat belt device 200 according to the present invention will be described. In a non-operating state of the forklift 100 (a state in which no one is in the driving unit 5), the seat belt 19 pulled out from the belt storage unit 17 is attached to the front column 3a diagonally to the left front of the driver seat 6. It is connected with the hook part main body 23 pulled out from. Since both the seat belt 19 and the hook portion main body 23 are urged in the winding direction with a predetermined tension, the seat belt 19 does not hang down. Since the belt storage portion 17 is installed on the right side of the driver's seat 6, the seat belt 19 connected to the hook portion main body 23 is a plan view of the space portion Q <b> 1 formed between the driver's seat 6 and the handle 7. In the space Q2 (see FIG. 2) formed diagonally across and above the handle 7. Here, when the driver gets into the driving unit 5 of the forklift 100, the driver often gets in from the step 15 on the right side of the driver's seat 6 with few obstacles such as the operation lever 8 or the like. In this case, the driver slides his / her torso 21 into the space Q1 formed between the driver's seat 6 and the handle 7 and presses the seat belt 19 away from the driver's seat 6 by the torso 21. Sit in the driver's seat 6. For this reason, the seat belt 19 arranged in a tension state does not become an obstacle when the driver is seated in the driver's seat 6.

  At this time, the seat belt 19 is hung on a part (right side part) of the trunk 21 of the driver seated in the driver's seat 6. Further, a seat belt 19 is positioned above the handle 7 in a tensioned state. For this reason, the driver seated in the driver's seat 6 visually recognizes the seat belt 19 with certainty.

  The driver who is seated in the driver's seat 6 can release the connection between the seat belt 19 and the hook portion main body 23 as it is. That is, the connecting portion between the seat belt 19 and the hook portion main body 23 is disposed in the space Q2 above the handle 7, and the driver seated on the driver's seat 6 reaches out as it is and hooks with the seat belt 19. It is possible to release the connection by placing a hand on the unit main body 23.

  The driver who has released the connection between the seat belt 19 and the hook portion main body 23 holds the seat belt 19 while holding the front end of the released seat belt 19 (the portion supporting the tongue 19a). The buckle 18 is engaged while being wound around the portion 21. As a result, the driver can easily wear the seat belt 19.

  When the driver who has finished the operation of the forklift 100 leaves the driver's seat 6, the operation in the reverse process is performed. That is, when the engagement between the seat belt 19 and the buckle 18 is released, the hand holding the front end portion of the seat belt 19 is moved as it is, and the tongue 19a of the seat belt 19 is engaged with the hook body. It hooks on the hook part 23a of 23. At this time, it is not necessary for the driver to change the seat belt 19 or to change the position where the driver holds the seat belt 19, and the operation is easy. Thereby, a passage for getting off is formed on the left side of the driver. The driver rotates his / her torso 21 leftward (counterclockwise in plan view), gets on the step 15 and gets off. At this time, there is no possibility that the driver will catch the seat belt 19.

  When a key switch (not shown) of the forklift 100 is turned off in a state where a sensor (not shown) is incorporated in the hook 22 and the connection between the seat belt 19 and the hook body 23 is released, A warning (for example, an alarm sound) may be issued. This prevents the driver from storing the seat belt 19 in the belt storing portion 17 as it is after the engagement between the seat belt 19 and the buckle 18 is released in order to get off the vehicle.

  The seat belt device 200 of the present invention only needs to add the hooking portion 22 to the existing forklift 100. For this reason, it is possible to make the driver securely wear the seat belt 19 with an inexpensive and simple configuration.

  In the case of the seat belt device 200 of the present embodiment, the case body 24 of the hook portion 22 is attached to the front column 3a of the forklift 100. However, you may attach to parts other than the front support | pillar 3a, for example, the part of the instrument panel of the driving | operation part 5. FIG.
