The object of the present invention is to provide a latching device for a truck engine cover that solves these problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a seat on the top surface of the engine cover whose rear end is pivotally connected to the vehicle body, so that the engine cover can be opened and closed together with the seat. This is a locking device for an engine cover of a truck, in which a protrusion is connected to the front end of the engine cover and is located below the seat and spaced a required distance from the bottom surface of the seat, and the engine cover is closed. When
An engagement fitting having a long hole is provided on a part of the vehicle body facing the protruding piece, and the protruding piece is rotatable around an axis facing in the same direction as the opening/closing direction of the engine cover. A locking rod is provided that faces in a direction perpendicular to the axis and can be fitted into the long hole of the engaging metal fitting at a required stopping position, and the locking rod is inserted into the long hole of the locking metal fitting. The stopper comes into contact with the stopper when the locking rod is rotated by the required angle, and the locking rod enters the rotational path of the locking rod in the middle of its rotational path from insertion into the long hole until it abuts the stopper. A restraint means for applying a restraining force to the rotation of the locking rod is provided, and the locking rod is connected to an operating handle provided in a space between the lower surface of the seat and the protruding piece. .

(Function) According to the present invention, after the locking rod is inserted into the long hole of the engaging fitting, the locking rod is moved over the restraining member by the operation handle until it comes into contact with the stopper of the engaging fitting. The opening/closing body can be easily latched to the vehicle body by simply rotating it, and in this latched state, the restraint means restricts the locking rod from rotating in the opposite direction, preventing the vehicle from vibrating. However, the locking rod will not accidentally come off the locking metal fitting.

If you want to open the opening/closing body, use the operating handle to rotate the locking rod in the opposite direction to the above case.
It is sufficient to allow the locking member to climb over the restraining means and to remove the locking rod from the elongated hole.

In addition, the entire latching device is located directly under the seat when the engine cover is closed, and the operating handle etc. do not protrude forward from the seat, so the latching device or a part of it is placed directly under the seat when the engine cover is closed. There is no fear that it will hit the foot and hinder the movement of the foot, and the appearance is improved.

The operating handle 8 is tightly fitted to the shaft 6 by screwing a nut 9 onto the small diameter threaded portion 6d of the shaft 6 from above. .

An annular elastic body 10 is contracted between the projecting piece 2 a and the operating handle 8 and is centered around the shaft 6 .

This elastic body 10 is made of, for example, rubber or a soft synthetic resin material, and includes a protrusion 2a and an operating handle 8.
In addition to absorbing the vertical play between the projecting piece 2
It acts to provide a resistance force when the operating handle 8 rotates with respect to a, that is, a force that prevents the operating handle 8 from rotating.

On the side of the vehicle body 1 corresponding to the locking rod 7, there is a locking metal fitting 1.
1 is provided.

This engagement fitting is formed by press working a metal plate, and mounting pieces 13 in which mounting holes 12 are bored are formed on both left and right sides.

In the middle between both mounting pieces 13, 13, there is a front half part 14.
An intermediate protruding part 16 is formed in which the rear part 15 and the rear part 15 are shifted from side to side to protrude upward, and a long hole 17 that is long in the left-right direction is bored in the center thereof.

The first half 14 and the second half 15 of the intermediate raised portion 16 are 180° symmetrical with respect to the center of the elongated hole 17, and one of the rising walls 14a, 15a
and the other rising walls 14b and 15b rise from a portion located in the middle of the elongated hole 17, respectively.

Each front half 14 and rear half 15 of the intermediate raised portion 16
Left and right rising walls 14a, 14b, 15 in
Approximately in the center of the upper walls 14c, 15c between the upper walls 14c, 15b are formed protrusions 14d, 15d which are long in the front-rear direction and curve downward into an arc shape.

In addition, each protrusion 14d, 15d and the rising wall 14
b, 15b is equal to or slightly larger than the width of the locking rod 7, and the distance between the front half 1
The protrusion 14d of No. 4 is the rising wall 15b of the rear half 15.
In addition, the protrusions 15d of the rear half 15 are aligned with the rising walls 14b of the front half 14 in the front and rear directions, respectively.

Further, the length of the long hole 17 is the same as the length of the locking rod 7, and the width of the long hole 17 is the same as or slightly longer than the horizontal width of the locking rod 7, respectively.

A restraining means is formed to apply a restraining force to the rotation of the locking rod 7.

Note that an appropriate space is formed between the operating handle 8 and the lower surface of the seat 4 to allow a hand to be inserted.

Next, the operation and handling of this embodiment will be explained.

In order to close and lock the engine cover 2 from the open state, the locking rod 7 must be inserted into the elongated hole 17.
Close the engine cover 2 while facing in the same direction as the longitudinal direction.

When opening the engine cover 2, the locking rod 7 is opened in the same direction as the longitudinal direction of the elongated hole 17, so if the locking rod 7 is left in the same position, the engine will open. There is no need to rotate the locking rod 7 when closing the cover 2.

When the engine cover 2 is closed in this state, the locking rod 7 fits into the elongated hole 17 (see FIG. 3).

Next, when the operating handle 8 is rotated approximately 90 degrees clockwise when viewed from above in FIG. 1, the locking rod 7 is
After climbing over the protrusions 14d and 15d, it comes into contact with the inner surfaces of the rising walls 14b and 15b, which are stoppers, and stops.

In this state, both ends of the locking rod 7 are narrowed by the rising walls 14b, 15b and the protrusions 14d, 15d in the front half 14 and rear half 15 of the intermediate raised portion 16, so that the locking rod 7 The rotation in the reverse direction is restricted, and even if the automobile vibrates, the locking rod 7 will not accidentally come off from the engagement fitting 11.

When it is desired to open the engine cover 2, the operating handle 8 is rotated 90 degrees in the opposite direction to that described above.

Then, after the locking rod 7 rides over the protrusions 14d and 15d, it comes into contact with the rear edge 14f of the rising wall 14b and the front edge 15f of the rising wall 15b and stops.

From this state, when the front end of the engine cover 2 is lifted upward, the locking rod 7 is disengaged upward through the long hole 17, and the engine cover 2 can be opened.

(Effects of the invention) According to the invention, the following effects can be achieved.
