Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a tonneau board for hiding luggage loaded in a luggage compartment behind a rear seat of an RV vehicle.
The present invention relates to an improvement in a lock device that is removably locked to both side walls of a luggage compartment.

[0002]

2. Description of the Related Art As a conventional lock device of this kind, there is one disclosed in Japanese Utility Model Laid-Open No. 3-82650. Although not specifically shown, the conventional locking device is provided with concave holder discs opposed to both side walls of the luggage compartment of the RV car, and provided on each of the holder discs on both sides of the tonneau board described above. By fitting the tip of the mounting pin, the locked state of the mounting pin is obtained, and the tonneau board is to be mounted horizontally in the luggage compartment. However, the locking structure of the mounting pin is L-shaped. A cylindrical housing having a guide groove is provided on both sides of the tonneau board, and the mounting pin is supported together with the compression coil spring in each housing, and the tip of the mounting pin always projects in the direction of the holder board. In addition, the operation lever connected to the mounting pin is movably faced in the guide groove of the housing.

[0003] Therefore, when actually installing the tonneau board on the cargo room side, if the operation lever is locked to the L-shaped end of the guide groove, the tip of the mounting pin is compressed by the compression coil spring. After being immersed in the housing against the urging spring pressure, after obtaining such a sunk state, while applying each mounting pin to the corresponding holder board, the guide groove of the operation lever is reversed. When the lock on the L-shaped end is released, the tip of the mounting pin automatically fits inside the holder board by the biasing spring pressure, so that each mounting pin is locked to the holder board. At the same time, the tonneau board is mounted in a horizontal state.

When the tonneau board is to be removed, the operating lever is also locked to the L-shaped end of the guide groove, and the tips of all the mounting pins are similarly lowered into the housing. Since the locked state of the pin with respect to the holder board is released, the tonneau board can be removed.

[0005]

Therefore, in the conventional locking device, the mounting pin is locked to the holder board or unlocked as necessary, so that the tonneau board is moved to the cargo room side. Since it can be attached and detached, it has a certain degree of convenience, but in that work, each time, the movement of the operating lever in the guide groove is obtained, and the tip of all the mounting pins is removed. There is a dislike that the locking and unlocking of the mounting pin becomes naturally difficult because the housing must be individually protruded and retracted from the housing. It goes without saying that the locking and unlocking of the mounting pin becomes difficult, and accordingly, the attaching and detaching of the tonneau board also becomes difficult.

[0006]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional lock device. It has a movable striker and a rotatable operation lever for operating the striker. The striker has a protruding part on the side facing the operation lever, and is always resilient in a rising direction by the spring pressure of a spring. The operating lever has a pressing portion that presses the protruding portion on the side facing the striker against the urging spring pressure of the spring, and is locked by the striker when the operating lever is rotated to the operating position. A configuration having a holder wall abutting from below on the shaft-shaped member is adopted.

According to a second aspect of the present invention, based on the first aspect, when the shaft member is locked by the striker, a structure is adopted in which the holder wall of the operation lever elastically holds the shaft member with the striker. .

According to a third aspect of the present invention, based on the second aspect, the holder wall is provided on the operation lever via a hinge so as to be able to bend, and the first wall portion abuts on the shaft member from below. And a second surface portion orthogonal to the first surface portion and elastically holding a shaft-like member between the striker and the striker. The hinge portion is provided at the base of the second surface portion.

According to a fourth aspect of the present invention, based on the first to third aspects, a configuration is adopted in which a cover body is laid over the striker and the holder wall.

Therefore, according to the first aspect of the present invention,
If the striker is lowered by the shaft-like member against the biasing spring pressure and the shaft-like member is moved inside the striker, the striker rises by the biasing spring pressure and the shaft-like member is moved in place. Can be locked. Conversely, when releasing the locked state of the shaft-shaped member, when the operation lever is rotated and the protrusion of the striker is pressed by the pressing portion, the striker descends against the biasing spring pressure. At the same time, the holder lever on the operation lever side comes into contact with the shaft member from below, and while the striker is lowered, the operation lever is temporarily restrained at the operation position and the locked state of the shaft member by the striker is released. Thereafter, the shaft member is pulled out of the locked position as it is. Therefore, the locking and unlocking of the shaft member becomes very simple, and the workability can be greatly improved, and when the shaft member is pulled out of the lock position, the striker rises again by the biasing spring pressure. The operating lever can be automatically returned to the standby position.

According to the second aspect of the present invention, the locked shaft member can be elastically held between the striker and the holder wall of the operation lever, so that the unnecessary rattling of the locked shaft member is prevented. It can be effectively prevented and when the locked state of the shaft member is released, if the shaft member is lightweight, the shaft member can be automatically pushed out in the pull-out direction only by turning the operation lever Becomes

According to the third aspect of the present invention, the holder wall is composed of a first surface portion and a second surface portion which are orthogonal to each other, and the rotation of the operation lever is related to the fact that the hinge portion is present at the base of the second surface portion. In the process, the contact state of each surface portion with the shaft-like member is rapidly changed, so that it is not necessary to rotate the operation lever at a large angle, and the operability is improved.

According to the fourth aspect of the present invention, the presence of the cover body prevents the shaft member in the locked state from coming off, and also clamps the shaft member between the holder wall and the cover body. Therefore, when the operation lever is rotated and the operation lever is restrained at the operation position, a reliable restrained state can be obtained.

It is designed to be supported inside.

Therefore, the locking device L according to the present embodiment
The lock device L is, as shown in FIG.
A striker 12 is vertically movably supported on a box-shaped housing 11 having an open upper surface fixed in the space 3 of each of the receiving rails 1 and an operation lever 13 is supported by a support shaft 14.
The lock pin P1 on the front side of the tonneau board B is locked and unlocked by rotatably supporting the striker 12 and the operating lever 13 through the lever to organically act. Things. In the figure, 1
5 is an operation lever 1 described below from above the striker 12.
3 is a cover member straddled between the three raised portions 20.

The former striker 12 is an integrally molded product of synthetic resin, and has a projection 16 integrally formed on the side facing the operation lever 13 and a tapered shape 17 provided on the opposite upper side to provide a housing. Boss 1 between bottom of 11
The structure is such that the spring force of the compression coil spring 18 mounted via the first spring 1a constantly urges in the upward direction.

The operating lever 13 is an integrally molded product of a synthetic resin, and presses the protruding portion 16 against the distal end facing the striker 12 against the urging spring pressure of the compression coil spring 18. The pressing portion 19 is formed integrally, a hollow raised portion 20 is provided behind the pressing portion 19, and the holder wall 21 has an inverted U-shape on a side surface of the raised portion 20 on the pressing portion 19 side. It is configured to be continuously connected to bend via the slit 22. As shown in the figure, the holder wall 21 has a first surface portion 21a which abuts against the mounting pin P1 from below, and a mounting pin P1 which is orthogonal to the first surface portion 21a and which is held between the striker 12 and the first surface portion 21a. Hinge portion 21c which promotes bending of holder wall 21 inward and outward at the base of second surface portion 21b.
Has existed.

Therefore, when the mounting pin P1 of the tonneau board B is locked to both side walls of the luggage compartment by using the lock device L having such a configuration, and the tonneau board B is horizontally mounted in the luggage compartment, Although not specifically shown, while supporting the mounting pins P2 on the rear side in the recesses 2 of the left and right receiving rails 1, the guide action of each receiving rail 1 is obtained to receive the mounting pins P1 on the front side. 1 and the cover body 15, the mounting pins P1 collide with the side face of the striker 12 to which the tapered shape 17 is provided, and the striker 12
Is lowered against the biasing spring pressure of the compression coil spring 18, and thereafter, if the mounting pin P1 is moved to the inside of the striker 12 as shown in FIG. The pressure rises and the mounting pin P1
Lock in place. In this case, it is also possible to lock the mounting pin P1 on the front side first and then support the mounting pin P2 on the rear side in the recess 2 later.

Therefore, in any case, this allows R
In the cargo room of the V-vehicle, the tonneau board B will be mounted horizontally with the help of the receiving rail 1,
At this time, as shown in the drawing, the mounting pin P1 in the locked state is moved between the striker 12 and the holder wall 2 of the operation lever 13.
Since it is elastically held between the first and second surface portions 21b, there is no fear that the left and right mounting pins P1 are loosely played and the mounting state of the tonneau board B becomes unstable.

Conversely, when releasing the locked state of the mounting pin P1 and removing the tonneau board B from the luggage compartment, the operation lever 13 is pivoted about its support shaft 14 while pulling up the rear end of the operation lever 13. When the projecting portion 16 of the striker 12 is pressed by the pressing portion 19 by rotating clockwise in the drawing, the striker 12 initially resists the urging spring pressure of the compression coil spring 18 as shown in FIG. At the same time, the second surface 21b of the holder wall 21 is also attached to the mounting pin P1.
While being in contact with the side surface of

When the operation lever 13 is further raised to the final operation position by continuing the rotation operation, the striker 12 is completely lowered into the housing 11 as shown in FIG. The first surface 21a of the wall 21 switches and comes into contact with the mounting pin P1 from below. In this case, the weight of the mounting pin P1 including the tonneau board B itself is reduced by the biasing spring of the compression coil spring 18. If the weight overcomes the pressure, the operation lever 13 can be restrained at the operation position while the striker 12 is completely lowered, although temporarily, so that the mounting pin by the striker 12 can be restrained. P1
The locked state of is easily released. Moreover, in such a restrained state, the operating lever 13 does not return to the standby position even if the hand is released.

In this case, as described above, the holder wall 21 is composed of the first surface 21a and the second surface 21b which are perpendicular to each other, and the hinge 21c is present at the base of the second surface 21b. In the course of the rotation of the operation lever 13, the contact state of each of the surface portions 21a and 21b with the mounting pin P1 is rapidly switched, and the first surface portion 21a can be instantaneously contacted with the mounting pin P1 from below. The unlocked state of the mounting pin P1 can be easily obtained without rotating the lever 13 at a large angle.

When the operation lever 13 is constrained to its operation position, it is sufficiently possible to constrain the operation lever 13 to the operation position only by the weight of the mounting pin P1. If it is configured so as to be sandwiched between the portion 21a and the cover body 15, the attachment pin P1 can be effectively prevented from coming off, and the operation lever 13 can be more securely restrained, so that there is no fear of malfunction. Almost disappears.

Therefore, after the left and right operation levers 13 are restrained at the operation position, if the left and right mounting pins P1 are pulled out in synchronization with the arrow direction, the tonneau board B can be easily removed from the luggage compartment. However, when the mounting pin P1 is pulled out, the restrained state of the operation lever 13 is released.

When the striker is moved inward, the striker is raised by the biasing spring pressure, and the shaft member can be locked in place. Conversely, when releasing the locked state of the shaft-shaped member, when the operation lever is rotated and the protrusion of the striker is pressed by the pressing portion, the striker descends against the biasing spring pressure. At the same time, the holder lever on the operation lever side comes into contact with the shaft member from below, and while the striker is lowered, the operation lever is temporarily restrained at the operation position and the locked state of the shaft member by the striker is released. Thereafter, the shaft member is pulled out of the locked position as it is. Therefore, the locking and unlocking of the shaft member becomes very simple, and the workability can be greatly improved, and when the shaft member is pulled out of the lock position, the striker rises again by the biasing spring pressure. The operating lever can be automatically returned to the standby position.

According to the second aspect of the present invention, the locked shaft member can be elastically held between the striker and the holder wall of the operation lever, so that unnecessary rattling of the locked shaft member can be effectively prevented. At the same time, when releasing the locked state of the shaft-shaped member, if the shaft-shaped member is lightweight, the shaft-shaped member can be automatically pushed in the pulling-out direction only by rotating the operation lever.

According to a third aspect of the present invention, the holder wall comprises a first surface portion and a second surface portion which are orthogonal to each other, and the hinge portion is provided at the base of the second surface portion. Since the contact state of each surface portion with the shape member is rapidly changed, it is not necessary to rotate the operation lever at a large angle, and the operability is improved.

According to the fourth aspect of the present invention, it is possible to prevent the locked shaft member from coming off due to the presence of the cover member, and also to hold the shaft member between the holder wall and the cover member. Therefore, when the operation lever is rotated and the operation lever is restrained at the operation position, a reliable restrained state can be obtained.
