[Prior Art]

 In industrial vehicles such as ordinary battery-powered forklifts, a top panel is mounted on the vehicle body so that it can be opened and closed using hinges, and one end of this top panel and a vehicle body-side member are elastically supported in a removable manner. A lock mechanism is provided.

As an example of the lock mechanism, the structure shown in FIGS. 5 and 6 is known. In the case of the example in FIG. 5, the support bracket 5 is fixed to the vicinity of the upper end of the center plate 1 which is the vehicle body side member by using bolts 3 and 3, and is integrally provided on the upper end of the support bracket 5. The mount rubber 7 is fixed on the support plate 5a. A support plate 7a provided at the lower end of the reinforcement 9 supported inside the top panel 11 is in contact with the upper surface of the mount rubber 7. A substantially U-shaped hook member 13 is fixed to one end of the top panel 11. Reference numeral 15 is a top front panel disposed on the front FR side of the center plate 1, and a catch bracket 19 is fixed near the upper end of the top front panel 15 using bolts 17, 17. An operation piece 21a of a catch member 21 is pivotally supported on the catch bracket 19, and a hook piece 21b is pivotally supported at a substantially intermediate portion of the operation piece 21a.

According to this structure, when the top panel 11 is locked, the hook piece 21b of the catch member 21 is locked to the U-shaped hook member 13 fixed to the top panel 11, and the operation piece 21a is rotated. As a result, the top panel 11 is locked to the top front panel 15. At this time, the mount rubber 7 elastically supports between the center plate 1 and the reinforcement 9 on which the top panel 11 is supported.

In the case of the example shown in FIG. 6, the support bracket 18 is fixed to the outer wall surface of the battery box 23, and the catch bracket 19 is bolted to the bosses 18 a, 18 a on the front surface of the support bracket 18. The operation piece 21a of the catch member 21 similar to the above example is pivotally supported on the catch bracket 19, and the hook piece 21b is pivotally supported at a substantially middle portion of the operation piece 21a. ing. Further, a mount rubber 7 is fixed on a rubber support bracket 25 that is horizontally projected near the upper end of the battery box 23, and the lower end of the reinforcement 9 supported inside the top panel 11 is the above-mentioned. It is in contact with the mount rubber 7. Further, a U-shaped hook member 13 is fixed to one end of the top panel 11.

Therefore, when the top panel 11 is locked, the hook piece 21b of the catch member 21 is locked to the U-shaped hook member 13 of the top panel 11 and the operation piece 21a is rotated as in the example shown in FIG. By moving, the top panel 11 is locked to the battery box 23 through the support bracket 18, and the mount rubber 7 fixed to the rubber support bracket 25 elastically supports the top panel 11 and the battery box 23. (For the above configuration, see, for example, the Parts Catalog M02 series, 1990 edition issued by Nissan Motor Co., Ltd.).

[Problems to be solved by the device]

 However, in the case of such a conventional top panel lock structure for an industrial vehicle, the relative positional accuracy between the mount bar 7 and the catch member 21 is not necessarily good, and the catch member 21 and the top panel 11 are However, there is a disadvantage that the locking mechanism of the above becomes structurally complicated, and an extra die cost is required at the time of manufacturing, which is disadvantageous in terms of cost.

Particularly in the case of the example shown in FIG. 5, the mount rubber 7 is between the center plate 1 and the reinforcement 9, while the catch member 21 is a member different from the center plate 1. Since it is provided on the front surface of the top front panel 15, the assembling property of the mount rubber 7 and the catch member 21 and the positional accuracy of the catch member 21 and the mount bar 7 may be deteriorated. Since it is necessary to provide an escape hole for the bolt head in the support bracket 5 in order to fix 7 to the support plate 5a of the support bracket 5, the mold cost at the time of molding becomes high, which causes an increase in cost. Difficulties arise.

On the other hand, there is a fear that the function of the mount rubber 7 may be deteriorated due to the loosening of the bolts that fix the mount rubber 7, and the mount rubber 7 and the catch member 21 may be located closer to the center plate 1 than the center plate 1. Also, because it is located on the front FR side, the leg space of the occupant is narrowed due to layout restrictions, and the legs of the occupant interfere with the top panel 11 when traveling, which causes discomfort. There is a problem.

On the other hand, in the case of the example shown in FIG. 6, since the catch bracket 19 is fixed directly to the outer wall surface of the battery box 23, a dedicated battery box 23 suitable for each vehicle must be provided individually. In addition, the existing battery box cannot be used, and the battery box lacks versatility.

Therefore, the present invention solves the problems of the conventional top panel lock structure for an industrial vehicle, improves the relative positional accuracy between the mount rubber and the catch member, and It is an object of the present invention to provide a top panel lock structure that simplifies the lock mechanism between the top panel and the top panel and can reduce the manufacturing cost.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a lock structure in which a top panel of an industrial vehicle such as a forklift is hermetically sealed in a detachable manner to a center plate which is a vehicle body side member by using a catch member and a mount rubber. A mount bracket protruding above the upper end of the center plate is fixed to the center plate, a catch member is arranged on the front side of the mount bracket, and a mount rubber is attached to the upper end on the rear side of the mount bracket. It has a top panel lock structure with a fixed rubber plate.

[0013]
