Description

  The present invention relates to an engine hood opening and closing device for an industrial vehicle, and more particularly to an engine hood opening and closing device for an industrial vehicle having an engine hood that is rotated in the horizontal direction with a connecting pin as a fulcrum.

As a conventional engine hood opening and closing device for an industrial vehicle, for example, a left and right split type engine hood support device in a forklift disclosed in Patent Document 1 is known.
In this type of engine hood opening and closing device, the engine hood that covers the upper part of the vehicle body is composed of an engine hood that is asymmetrically divided into two left and right, and a driving seat is provided on one of the engine hoods.
Each engine hood is rotated in the horizontal direction using a hinge provided near the rear pillar as a rotation fulcrum.
When the engine hood is open to the left and right, the upper part of the vehicle body is exposed.

By the way, in this type of engine hood opening and closing device, the load due to the weight of the engine hood and the accessories provided in the engine hood is usually concentrated on the connecting pin of the hinge.
When such a load acts on the connecting pin, it is unavoidable that the engine hood bends. For example, the end of the engine hood farthest from the fulcrum in the engine hood may hang down from a normal position.
If the end of the engine hood is lowered from the normal position, the engine hood may interfere with the vehicle body or other parts.

In order to solve such a problem, for example, an engine hood opening / closing device 52 shown in FIG. 8 has been conventionally proposed.
In the engine hood opening and closing device 52, the bracket base member 53 is attached to the rear pillar 51 so as to be directed forward.
A fixing bracket 54 that supports the engine hood 55 is fixed to the bracket base member 53.
A plurality of elongated holes 54 a are formed near the bracket base member 53 of the fixed bracket 54.
These long holes 54a are arranged vertically in the fixed bracket 54, and the long diameter of the long holes 54a coincides with the front-rear direction.

When the fixing bracket 54 is attached to the bracket base member 53, the bolt 60 is inserted through the elongated hole 54a (for convenience of explanation, the upper and lower bolts 60 show the shaft portion in FIG. 8).
The fixing bracket 54 is attached to the bracket base member 53 by tightening the bolt 60 inserted through the long hole 54a.
At the front end of the fixed bracket 54 on the side of the engine hood 55, shaft holding portions 58 and 59 that respectively hold upper and lower connecting pins 56 and 57 that serve as pivot points provided on the engine hood 55 are provided.
The engine hood disposed at the front portion of the fixed bracket 54 rotates in the horizontal direction with the connecting pins 56 and 57 as fulcrums.

The front-rear position of the fixed bracket 54 with respect to the bracket base member 53 can be adjusted according to the long diameter of the long hole 54a.
Further, the inclination of the fixed bracket 54 with respect to the bracket base member 53 can be adjusted by the presence of the clearance between the short diameter of the long hole 54 a and the outer diameter of the bolt 60.
Specifically, for example, the inclination of the fixing bracket 54 is adjusted so that the fixing bracket 54 is changed from a state indicated by a two-dot chain line to a state indicated by a solid line in FIG.
By adjusting the inclination of the fixed bracket 54, the inclination of the axis S of the connecting pins 56 and 57 is changed.
Adjustment of the front-rear position and inclination of the fixed bracket 54 with respect to the bracket base member 53 requires releasing the tightening of the bolts 60 inserted in the respective long holes 54a.
Japanese Utility Model Publication No. 5-14951 (pages 1-4, 2 and 8)

However, in the prior art shown in FIG. 8, when the tightening of the bolt 60 inserted through the long hole 54a is released, the fixing bracket 54 moves steplessly with respect to the bracket base member 53 according to the range of the long hole 54a. Since it is allowed, it is difficult to grasp the adjustment amount of the front-rear position and the inclination of the fixed bracket 54.
When adjusting the position of the engine hood 55 using the bolt 60 inserted through the long hole 54a, it is difficult to appropriately adjust the front and rear position and the inclination of the engine hood 55, and the position adjustment is limited to the position adjustment in a specific direction. .
Moreover, after the position of the engine hood 55 is adjusted, if the tightening of the bolt 60 in the long hole 54a is loosened due to the use of the vehicle, there is a problem that the readjustment of the fixing bracket 54 becomes necessary.

  The present invention has been made in view of the above problems, and an object of the present invention is to adjust the position of the engine hood that rotates in the horizontal direction with the connecting pin as a fulcrum and to adjust the position in multiple directions. To provide an engine hood opening and closing device for industrial vehicles.

  To achieve the above object, the present invention provides a fixed bracket provided on a vehicle body, a connecting pin provided on the fixed bracket and having an axis extending in the vertical direction, and an engine hood connected to the vehicle body via the connecting pin. The engine hood includes a hood main body that covers an upper portion of the vehicle body, a movable bracket that is connected to the hood main body and passes through the connection pin, and the engine hood uses the connection pin as a fulcrum. In an engine hood opening and closing device for an industrial vehicle that opens and closes the engine hood by turning in a horizontal direction, the fixed bracket or the movable bracket has an eccentric hole into which the connection pin is inserted, and upper and lower portions of the connection pin. Each having a pair of upper and lower positioning members and a stopper member for defining a fixing position of the positioning member, Position of the movable bracket with respect to the fixed bracket, and is possible, characterized in defined according to the position of the eccentric hole to be defined for each fixed position of the positioning member.

In the present invention, each stopper member defines a fixed position of the positioning member with respect to the fixed bracket or the movable bracket.
Since the fixing position of the positioning member is defined by the stopper member, the position of the eccentric hole in the positioning member is defined.
The position of the eccentric hole in the positioning member is defined for each fixed position, and the position of the movable bracket relative to the fixed bracket is defined according to the position of the eccentric hole.
By defining the position of the movable bracket relative to the fixed bracket, the position of the engine hood relative to the fixed bracket is defined.
In addition, the position of the movable bracket with respect to the fixed bracket refers to a position related to horizontal movement in multiple directions including front and rear, left and right directions, and a position related to inclination in multiple directions including front and rear, left and right directions.
If there are a plurality of positioning positions of the positioning members, the position of the engine hood relative to the fixing bracket can be adjusted stepwise and multi-directionally by changing the fixing positions of the pair of upper and lower positioning members.

  In the present invention, in the engine hood opening and closing device for an industrial vehicle described above, the positioning member has a polygonal outer periphery in plan view having a plurality of flat surfaces, and the stopper member is a specific flat surface in the outer periphery. It may have a defining surface that defines the fixed position of the positioning member by contact with the positioning member.

In this case, the defining surface provided in the stopper member defines the fixed position of the positioning member by contacting a specific flat surface of the outer periphery of the polygonal shape in plan view of the positioning member.
Since the outer periphery has a polygonal shape, each flat surface constituting the outer periphery maintains a predetermined angle with the adjacent flat surfaces.
When the flat surface that contacts the prescribed surface of the stopper member is changed, the fixed position of the positioning member is changed by a predetermined angle.
Since the fixed position of the positioning member is defined for each flat surface, the position of the eccentric hole can be changed in stages corresponding to the flat surface, and the position of the engine hood relative to the fixed bracket is the shape of the outer periphery of the positioning member It is adjusted step by step to correspond to.

  According to the present invention, in the engine hood opening and closing device for an industrial vehicle described above, the stopper member is fixed by a shaft member whose axis is up and down with respect to the fixed bracket or the movable bracket, and the connecting pin and the shaft member An axis center line that horizontally connects the two axis centers may be non-parallel to the prescribed plane.

In this case, the orientation of the prescribed surface of the stopper member when the stopper member is used with the front and back reversed can be made different from the orientation of the prescribed surface when the stopper member is used without being reversed.
The number of fixed positions of the positioning member is determined by the number of flat surfaces on the outer periphery, but by using the stopper member in both the front and back states, the number of fixed positions can be increased as compared with the case where the stopper member is used without reversing the front and back. Can do a lot.
If the fixing position of the positioning member increases, the position of the engine hood can be finely adjusted stepwise.

Shaft holes 14 are provided in the vicinity of the front end of the fixed bracket 13, and the upper and lower shaft holes 14 have a common axis.
These shaft holes 14 are holes through which connecting pins 15 that connect the engine hood 16 and the vehicle body 10 are inserted.

The connecting pin 15 has a pin main body portion 15a corresponding to the shaft hole 14 and a head portion 15b for preventing the pin main body portion 15a from being formed at one end of the pin main body portion 15a.
A tapered surface 15c for facilitating insertion of the connecting pin 15 into the shaft hole 14 is formed at the other end of the pin body portion 15a.
The connecting pin 15 inserted through the shaft hole 14 has an axis S in the vertical direction. In this embodiment, the connecting pin 15 is fixed to the fixed bracket 13.

The engine hood 16 includes a hood main body 16a that covers an upper portion of the vehicle body 10, and a movable bracket 16b that is connected to the hood main body 16a.
An upper recess 16c having a space is formed near the upper portion of the hood body 16a near the movable bracket 16b, and a lower recess 16d that forms another space is formed near the lower portion.
Bolt holes 16e and 16f for fixing bolts 20 as shaft members are formed in the upper recess 16c and the lower recess 16d of the hood body 16a.

The movable bracket 16b is connected to the corner of the hood body 16a near the fixed bracket 13 of the upper recess 16c and the lower recess 16d.
The movable bracket 16b is a hollow cylindrical body, and the hollow portion 16g formed in the movable bracket 16b allows the connection pin 15 to be inserted.
The movable bracket 16b is disposed between the upper and lower fixed brackets 13 in a state where the connecting pin 15 is inserted into the hollow portion 16g.
The dimensional difference between the diameter of the hollow portion 16g and the diameter of the pin main body portion 15a is set large, and a gap is formed between the outer peripheral surface of the pin main body portion 15a and the inner peripheral surface of the movable bracket 16b forming the hollow portion 16g. Is done.

As shown in FIGS. 3 and 4A, a positioning member 21 is provided at the upper end of the movable bracket 16b, and a part of the positioning member 21 is inserted into the upper opening of the hollow portion 16g.
The positioning member 21 has an insertion portion 21a inserted into the hollow portion 16g, a head portion 21b formed at an end portion of the insertion portion 21a, and an eccentric hole 21c penetrating the insertion portion 21a and the head portion 21b.

The insertion portion 21a is a cylindrical body that fits into the hollow portion 16g, and the head portion 21b has a nut shape having a hexagonal outer periphery in plan view.
The outer periphery of the head portion 21b in the positioning member 21 has six top portions 21e and flat surfaces 21d, and the adjacent flat surfaces 21d are in a relationship of maintaining an angle of 120 degrees with each other.
The eccentric hole 21c is a long hole formed at a position eccentric from the center of the positioning member 21, and the long diameter of the long hole coincides with the direction toward the top 21e on the front side.
Since the positioning member 21 has the eccentric hole 21c, at the fixed position of the positioning member 21 shown in FIG. 4 (a), the thickness between the top 21e on the head 21b and the eccentric hole 21c is the rear side. A wall thickness difference that is thinner than the wall thickness between the top portion 21e and the eccentric hole 21c is set.
The fixed position of the positioning member 21 is defined by the stopper member 22.

The stopper member 22 is a plate-like body, and has an insertion recess 23 that allows the positioning member 21 to be inserted from a specific direction, and a bolt through hole 24 through which the fixing bolt 20 is inserted.
The insertion recess 23 in the stopper member 22 is in contact with a flat surface 21d parallel to each other in the positioning member 21, and is formed by a pair of defining surfaces 22a parallel to each other and a bottom surface 22b formed between the defining surfaces 22a. .
The bolt through hole 24 is a through hole through which the fixing bolt 20 is inserted when the positioning member 21 is fixed to the upper surface of the upper concave portion 16c and the lower surface of the lower concave portion 16d of the hood main body 16a.
Since the positioning member 21 has a hexagonal outer periphery, the fixing position of the positioning member 21 is defined by the stopper member 22 around the axis S every angle of 60 degrees, and the number of fixing positions is six.

As shown in FIGS. 3 and 4B, a positioning member 21 having the same configuration as the positioning member 21 at the upper end is also provided at the lower end of the movable bracket 16b.
A part of the positioning member 21 on the lower end side is inserted into the lower opening of the hollow portion 16g.
Since the positioning member 21 on the lower end side has the same shape as the positioning member 21 provided on the upper end, the positioning member 21 has an insertion portion 21a inserted into the hollow portion 16g, a head portion 21b, and a long hole-shaped eccentric hole 21c. The outer periphery has six flat surfaces 21d and a top 21e.
In the fixing position of the positioning member 21 on the lower end side shown in FIG. 4B, the thickness between the top portion 21e on the front side and the eccentric hole 21c is the thickness between the top portion 21e on the rear side and the eccentric hole 21c. A wall thickness difference that is thicker than that is set.

The fixing position of the positioning member 21 on the lower end side is defined by another stopper member 22 having the same shape as the stopper member 22 that fixes the positioning member 21 on the upper end.
Similarly, the stopper member 22 on the lower end side has an insertion recess 23 and a bolt through-hole 24. The insertion recess 23 has a pair of defining surfaces 22a that contact the parallel flat surfaces 21d of the positioning member 21, and a bottom surface. 22b.
The bolt through-hole 24 is a through-hole through which the fixing bolt 20 is inserted when the positioning member 21 is fixed to the lower recess 16d of the hood main body 16a.

By the way, as shown in FIG. 5B, the stopper member 22 can be used as the stopper member 22 even if it is turned upside down.
In the state in which the positioning member 21 is inserted into the insertion recess 23, assuming an axial center line P that connects the center of the connecting pin 15 and the bolt 20 horizontally, the axial center line P is in a non-parallel relationship with the defining surface 22a.
Specifically, as shown in FIGS. 5A and 5B, an angle of 15 degrees is maintained between the axis P and the surface direction of the defining surface 22a.
An angle of 30 degrees is formed between the prescribed surface 22a of the stopper member 22 that is not reversed and shown in FIG. 5A and the prescribed surface 22a of the stopper member 22 that is reversed as shown in FIG. The

For this reason, the six fixing positions of the positioning member 21 defined by the defining surface 22a of the stopper member 22 that is not reversed are different from the six fixing positions defined by the stopper member 22 in the reversed state.
Accordingly, if the stopper member 22 is used with its front and back reversed, 12 fixing positions of the positioning member 21 are set.

Next, the operation of the engine hood opening / closing device 12 according to this embodiment will be described.
The position adjustment of the engine hoods 16 and 17 in the engine hood opening and closing device 12 according to this embodiment is performed by adjusting the inclination of the engine hoods 16 and 17 in multiple directions including the front and rear and left and right directions and in multiple directions including the front and rear and right and left directions. The position adjustment is related to the horizontal movement of.

First, position adjustment related to the inclination of the engine hood 16 will be described.
In this embodiment, the upper part of the connecting pin 15 is inserted into the eccentric hole 21c of the upper positioning member 21 shown in FIG. 4A, and the eccentric hole 21c of the lower positioning member 21 shown in FIG. 4B. The lower part of the connecting pin 15 is inserted through the.
In the upper part of the connecting pin 15, the thickness between the front-side top 21e and the eccentric hole 21c in the positioning member 21 is thinner than the thickness between the rear-side top 21e and the eccentric hole 21c.
In the positioning member 21 below the connecting pin 15, the thickness between the top portion 21e on the front side and the eccentric hole 21c is thicker than the thickness between the top portion 21e on the rear side and the eccentric hole 21c.

Therefore, as shown in FIG. 3, the upper and lower positioning members 21 of the movable bracket 16b cause the upper end of the movable bracket 16b to be directed rearward and the lower end to be directed forward, while floating the front of the engine hood 16. The engine hood 16 is inclined so as to sink the rear.
In this embodiment, the inclination of the engine hood 16 in the front-rear direction is adjusted. However, depending on the combination of the fixed positions of the positioning members 21, the engine hood 16 can be inclined in multiple directions other than the front-rear direction. .
The fixing position of the positioning member 21 is changed every 30 degrees around the axis S if the stopper member 22 is used upside down, and each eccentric hole 21c corresponding to the combination of the fixing positions of the positioning members 21 is changed. The position of the engine hood 16 is regulated by the position.

Next, position adjustment related to the parallel movement of the engine hood 16 will be described with reference to FIGS. 6 (a) and 6 (b).
The front and rear positions of the engine hood 16 shown in FIG. 6A are on the rear side compared to the front and rear positions of the engine hood 16 shown in FIG.
As shown in FIG. 6A, at the upper and lower ends of the connecting pin 15, the thickness between the front-side top 21e and the eccentric hole 21c in the positioning member 21 is such that the rear-side top 21e and the eccentric hole 21c The positioning member 21 is in a fixed position so as to be thinner than the intermediate thickness.
That is, both positioning members 21 are in the same fixed position with respect to the movable bracket 16b.
In the case of the engine hood 16 shown in FIG. 6B, on the contrary, at the upper and lower portions of the connecting pin 15, the thickness between the front-side top 21e and the eccentric hole 21c in the positioning member 21 is the rear-side top. It is the fixed position of the positioning member 21 that is thicker than the thickness between 21e and the eccentric hole 21c.

In this embodiment, the position adjustment is performed by moving the engine hood 16 in the front-rear direction. However, depending on the combination of the fixed positions of the positioning members 21, the engine hood 16 can be moved in the left-right direction.
The fixing position of the positioning member 21 is changed every 30 degrees around the axis S if the stopper member 22 is used upside down, and each eccentric hole 21c corresponding to the combination of the fixing positions of the positioning members 21 is changed. The distance and direction of the horizontal movement of the engine hood 16 are defined by the position.

In this embodiment, the position adjustment of one engine hood 16 has been described, but the other engine hood 17 includes a positioning member 21 and a stopper member 22 similar to the engine hood 16, although not shown.
Therefore, the position of the engine hood 17 can be adjusted in the same manner as the engine hood 16, and the inclination of the engine hood 17 with respect to the fixed bracket 13 is adjusted, or the position of the engine hood 17 with respect to the fixed bracket 13 is adjusted by horizontally moving the engine hood 17. You can do it.

According to the engine hood opening and closing device 12 according to this embodiment, the following operational effects can be obtained.
(1) Since the fixed position of the positioning member 21 is defined by the stopper member 22, and a plurality of fixed positions are set, the position of the eccentric hole 21c is defined for each fixed position. The position of the movable bracket 16b relative to the fixed bracket 13 is defined according to the combination of the positions of the eccentric holes 21c in the pair of upper and lower positioning members 21. By changing the fixing position of the pair of upper and lower positioning members 21, the position adjustment of the engine hood 16 with respect to the fixing bracket 13 can be performed stepwise and the position can be adjusted in multiple directions. The engine hood 17 can be adjusted in the same position. In addition, the position of the movable bracket 16b with respect to the fixed bracket 13 refers to a position related to tilting in multiple directions including the front / rear / left / right direction as well as a position related to horizontal movement in multiple directions including the front / rear / left / right direction.

(2) The defining surface 22a included in the stopper member 22 defines a fixed position of the positioning member 21 by contacting with a specific flat surface 21d of the outer periphery of the positioning member 21 having a polygonal shape in plan view. Since the outer periphery has a polygonal shape, each flat surface 21d constituting the outer periphery maintains a predetermined angle with the adjacent flat surfaces 21d. When the flat surface 21d that contacts the specified surface 22a of the stopper member 22 is changed, the fixing position of the positioning member 21 is changed by a predetermined angle around the axis S. Since the fixing position of the positioning member 21 is defined for each flat surface 21d, the position of the eccentric hole 21c can be changed in stages, and the positions of the engine hoods 16 and 17 with respect to the fixing bracket 13 are adjusted in stages. be able to. Since it is a stepwise adjustment, the operation of adjusting the positions of the engine hoods 16 and 17 is facilitated.

(3) The direction of the specified surface 22a in the stopper member 22 when the stopper member 22 is used upside down is different from the direction of the specified surface 22a when the stopper member 22 is used without being turned upside down. Can do. The number of fixed positions of the positioning member 21 is determined by the number of flat surfaces 21d. However, by using the stopper member 22 in both states, the number of fixed positions is more than when the stopper member 22 is used without turning the stopper member 22 upside down. Will also increase. By increasing the fixing position of the positioning member 21, the positions of the engine hoods 16 and 17 can be finely adjusted stepwise.

(4) Since the positions of the engine hoods 16 and 17 can be finely adjusted in stages, additional parts such as armrests and operation levers are added to the driving seat 18 and the engine hoods 16 and 17 later, Even if it is not provided, the combination of the fixed positions of the positioning members 21 where the engine hood 16 is in an appropriate position when the additional part is provided and the engine hood 16 when the additional part is not provided are appropriate If the combination of the fixed positions of the two positioning members 21 that are the correct positions is set in advance, the position adjustment of the engine hood 16 can be performed quickly regardless of the presence or absence of additional parts.

(5) Since the fixing position of the positioning member 21 is defined by the stopper member 22 and the stopper member 22 is fixed by the fixing bolt 20, the positioning member 21 is fixed when the stopper member 22 is fixed to the engine hood 16. There is no deviation from the position.
