Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to an industrial vehicle such as a forklift that uses LP gas as a fuel. More specifically, the seat on the hood interferes with the LPG cylinder when the engine hood is opened. The present invention relates to an engine hood of an industrial vehicle improved so as to avoid.

[Conventional technology]

2. Description of the Related Art As an LPG cylinder support device in an industrial vehicle, a structure in which a rear support of a head guard is used to support the LPG cylinder support device as shown in FIGS. 4 and 5 has been conventionally known.

That is, the cylinder support 10 includes a pair of left and right side plates 11 and three support rods 12 that connect the side plates 11 to each other.
A cylinder clamp 16 provided with a band 14 and a buckle 15 for tightening the LPG cylinder 13 on the cylinder support 10.
Is installed. Then, the hinge bracket 17 fixed to one side plate 11 is rotatably attached to a fixed bracket 20 provided on one rear column 19 of the head guard 18 via an upright shaft 21, and an engagement piece fixed to the other side plate 11 is provided. The structure is such that 22 is moored to a fixed bracket 23 provided on the other rear strut 19 via a connecting pin 24 that can be pulled out.

Therefore, in order to avoid the seat 26 and the like on the hood 25 from interfering with the LPG cylinder 13 when the engine hood 25 is opened rearward during inspection and maintenance work of the engine, the connecting pin 24 is pulled out prior to the work. ,
By rotating the cylinder support base 10 with the upright shaft 21 as a pivot, the LPG cylinder 13 is rotated to the rear side of the vehicle body, that is, to the non-interference area.

[Problems to be solved by the invention]

However, in the above support device, it is easy to forget to put the connection pin or forget to insert it if it gets caught in the busy work, so not only there is a possibility that the cylinder support base will rotate during traveling and an unexpected accident may occur, As described above, when opening the engine hood, it is necessary to turn the rear part of the vehicle body in advance and pull out the connecting pin to move the cylinder support to the non-interference area. If there is a problem, it is needless to mention again that the interference with the engine hood causes unexpected damage to each other.

The present invention provides a technical problem to be solved in which the engine hood itself is provided with an open posture that avoids interference with the cylinder, without intentionally turning the cylinder support to the non-interference area.

[Means for solving problems]

In order to solve the above problems, the present invention provides a fully open engine hood, a central hood in which the seat on which it is placed is limited to half-open without causing interference with the LPG cylinder, and interconnected on both sides of the central hood. A new configuration is adopted in which the side hood is divided into an allowable side hood, and the central hood is movably connected to the side hood via a delaying means for adjusting the maximum turning angle of the central hood.

The central hood and the side hood are pivotally supported at their rear upper edges so that they can be independently rotated and opened and closed, and both split edges of the central hood are bent inward to form the same split edge of the side hood. An overlapping sealing edge is formed, and an elastic sealing material such as soundproof rubber is interposed in the overlapping portion. The side hood, which does not have any obstacles such as seats, is allowed to be fully opened in the same way as a conventional gasoline vehicle, while the central hood is limited to half the range where the seat on which it is placed does not interfere with the cylinder. Thus, the maximum turning angle is adjusted by the retarding means operably connecting the central hood to the side hood.
One end of the retarding means is connected to the side hood and is inserted into the central hood, and the other end is constituted by a chain or a rod which has a play area and engages with the central hood. The side hood is equipped with each normal hood locking mechanism that locks it in the normally closed position and the open position for inspection and maintenance, and the central hood holds the side hood in either open or closed position. Similarly to the stop, the turning is restrained.

[Action]

Therefore, in order to open the engine hood for inspection and maintenance, if the closing and locking mechanism of the hood is released and the side hood is turned rearward, the play area of the retarding means that cooperates with the side hood is released. After that, the central hood is driven to rotate, and when the side hood reaches the fully open state, the central hood is held in the half open state with some margin left for interference with the cylinder. In this state, inspection and maintenance work is started after the side hood is locked, but although there is some dislike for the open space just above the engine due to the half-opening of the central hood, both sides, that is, the side The hood is wide enough to allow maintenance to be done without any substantial hindrance. Both hoods in the closed state have a soundproofing performance comparable to that of the integrated type because the dividing edges are tightly sealed by the overlapping portion with the elastic sealing material interposed.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 to 3, an engine hood 30 that is openably and closably arranged on the vehicle body so as to cover the engine room.
Is divided into a central hood 30A on which a seat 31 is placed on the upper surface and side hoods 30B arranged on both sides of the central hood 30A. The both side hoods 30B have connecting plates 32, 33 at their upper rear and lower end front edges. The central hood 30A and the armpit side hood 30B are independent from each other by pivoting the upper ends of their rear ends to the balance weights 35 through the hinges 34. It can be opened and closed by turning. However, since both sides of the central hood 30A are formed with a sealing edge 36 (only one is shown) that is bent inward and overlaps with the same edge of the side hood 30B, the side hood 30B precedes. Central hood 30
The turning open of A is inevitably impossible. Then, the outer surface of the sealing edge 36 or the side hood 30B that overlaps
An elastic seal member 37 such as a soundproof rubber is provided on the inner surface of the divided edge of the engine hood 30 together with an existing seal member (not shown) provided over the entire lower end edges of the hoods 30A and 30B. The airtightness is secured.

The side hood 70 that does not have an obstacle such as the seat 31
B is almost completely opened like the conventional engine hood, while the central hood 30A is mounted on the seat 31
However, the maximum turning angle is limited to a range that does not cause interference with the LPG cylinder 38 arranged on the vehicle body behind the seat 31, that is, the maximum turning angle so that the central hood 30A can be driven by the side hood 30B. It is adjusted by the delay means. The retarding means is composed of a chain body 40 or a rod, one end of which is fixed or pivotally attached to the inner surface of the connecting plate 32 and which extends through the through hole 39 of the central hood 30A. An engagement piece 41 is fixedly attached to the end and abuts against the through hole 39 with a predetermined floating area.

Therefore, when the engine hood 30 is opened for inspection and maintenance work, first, the hood closing locking mechanism (not shown) is released to open the side hood 30B in the opening direction (backward).
When it is turned to the side, the chain body 4 that cooperates with the side hood 30B
The free range of 0, that is, while the chain 40 itself is moving in the through hole 39, the central hood 30A is placed in an immovable state, and the loose moving range is exhausted, and the engaging piece 41 becomes the through hole 39 portion. The central hood 30A is suspended from the time of collision and starts driven rotation. Then, when the side hood 30B reaches the fully open state, the central hood 30A is held in the half open state with a slight margin left for interference with the LPG cylinder 38. The work is started after the side hood 30B is locked by the open locking mechanism (not shown) in such a state.
The central hood 30A is also suspended by the chain 40 so that the center hood 30A is reliably prevented from turning in the closing direction. It should be noted that the opening space directly above the engine becomes slightly narrower due to the half-opening of the central hood 30A, but on both sides, that is, the side hood 30.
Since the part B is open wide enough, it does not cause any trouble in the actual maintenance work.

When the armpit side hood 30B is turned in the closing direction after finishing the work, the central hood 30A is interlocked to return to the closed position first, and the armrest side hood 30B that has been subsequently returned is locked, so that both hoods 30A are closed. , 30B cover the engine room sufficiently tightly through the overlap of the dividing edges.

[Effect of device]

As described in detail above, the engine hood according to the present invention has the following excellent effects.

(1) Of the divided engine hoods, only the central hood on which the seat is placed is automatically limited to a turning angle that does not cause interference with the LPG cylinder, and the side hoods on both sides of the engine hood are completely open. Since it is widely turned into a state, it is possible to quickly perform inspection and maintenance by opening and closing the engine hood as with a gasoline vehicle, without taking a evasion measure against the existing LPG cylinder support device.

(2) Since the central hood is always driven by the opening / closing operation of the side hood, the hood can be opened and closed simply by operating the side hood.

(3) Since the divided edges of both hoods are tightly polymerized via the sealing material, even the divided hoods can exhibit a soundproofing function comparable to the integrated type.
