[0006]

The manual operation of opening and closing the lid member in the above-described lid member locking device involves opening and closing the lever and the stopper ring on the side and rear (or front) of the dust box. Two types of manual work were required, and in particular, manual work under the vehicle behind (or in front of) the dust bin was troublesome, and the workability of manually opening and closing the lid was poor.

[0007] Further, a lid member for closing the discharge port on the side wall surface of the dust input box is connected to the side wall surface of the dust input box in a single-opening manner,
Since the member for locking the lid member in the closing position is installed on the rear surface (or the front surface) closer to the discharge port of the trash input box, the opening and closing directions of the lid member and the opening and closing lever for opening and closing the lid member are substantially determined. I have. For this reason, there has been a problem that it is difficult to change the left and right opening directions of the lid member from the left single opening type to the right single opening type, or vice versa, on the side wall surface of the dust input box.

Further, the lid member is pressed against the side wall surface of the refuse input box by the tightening force of the opening / closing lever or the elasticity of the spring material so that the discharge port is firmly closed so as not to leak sewage.
As the final pressing force of the lid member on the side wall surface of the dust box is increased, the opening / closing lever needs to be opened and closed with a large force proportional to the final pressing force. Workability is even worse. Therefore,
Even if the final pressing force of the lid member on the side wall of the dust box is small, in order to make the lid member tightly adhere to the side wall surface of the dust box with good sealing performance, for example, a device as shown in FIG. I have.

As shown in FIG. 16A, the lid body 9 of the lid member 5 shown in FIGS. 14 and 15 is made of a rectangular box-shaped sheet metal, and a rubber elastic sealing material 18 is adhered inside the lid body 9. Fix with an agent. The sealing surface around the outer surface of the sealing material 18 is a flat surface slightly projecting from the opening end of the lid body 9, and a groove 19 is formed along the rectangular center line of the sealing surface. FIG.
The lid member 5 is removed from the dust opening box side wall surface m from the opened state of FIG.
To directly press the sealing material 18 against the side wall surface m as shown in FIG. 16B, and at this time, the sealing material 18 is vacuum-sucked to the side wall surface m so as to crush the groove 19. . Even if the final pressing force on the side wall surface m of the seal member 18 is small due to the vacuum suction, the seal member 18 adheres strongly to the side wall surface m, and the lid member 5 tightly seals the discharge port 4.

However, when the sealing member 18 of the lid member 5 is vacuum-sucked to the side wall m of the dust box, when the lid member 5 is opened, the sealing member adhered to the lid body 9 as shown in FIG. There is a case where only the lid main body 9 is opened while 18 is adsorbed on the side wall surface m of the refuse input box. If the sealing material 18 remains on the side wall surface m, the discharge port 4 is not opened and the wastewater cannot be discharged, and the sealing material 18 remaining on the side wall surface m is manually removed and adhered to the lid body 9 again. Such extra manual work is required, and the reliability of the lid member locking device deteriorates.

An object of the present invention is to provide a locking device for a lid member in which the procedure for opening and closing the lever is reduced to improve the operability of opening and closing the lid and the reliability of closing the opening is improved.

[0012]

A technical means for achieving the above object of the present invention is to provide a lateral single-opening type lid member for closing an opening by pressing the opening against a side wall surface around the opening, and a lid member having a tip end portion. An opening / closing lever rotatably connected to the outer surface of the lid member in the opening / closing direction of the lid member, a swinging end having a rear end portion rotatably connected to the opening / closing lever in the same direction as the opening / closing lever, and a claw locking portion at the tip end portion The hook is rotatably connected in the same direction as the lid member to a side wall surface near the opening / closing end of the lid member that closes the opening. A locking claw that is pushed down toward the outer surface of the distal end of the contacting lid member, and manually rotates the opening / closing lever toward the outer surface of the lid member that contacts the side wall surface. The locking claw tip presses against the outer surface of the lid member to swing the hook Characterized in that the over so as to pull it defeat rotate to lock in place.

[0013] An opening / closing lever for opening and closing the cover member installed on the side wall surface in a sideways opening manner;
All of the swing hook and the lock claw rotate and swing only in the same horizontal direction as the lid member, and the swing hook and the lock claw rotate and swing in accordance with the rotation of the opening / closing lever. Therefore, the lid member can be opened and closed by manually opening and closing only the opening and closing lever on only one side of the side wall. Also,
By rotating the opening / closing lever toward the outer surface of the lid member and pulling and rotating the lock claw on the lid member with the swing hook, the tip of the lock claw strongly presses the lid member against the side wall surface by leverage principle As a result, the final pressing force of the lid member on the side wall surface is large and stable.

Further, in the invention of claim 2 of the present invention, an adjusting screw for final pressing force adjustment directly pressed by the lock claw is screwed on a portion of the lid member pressed by the tip of the lock claw. This adjustment screw has its head pressed by a lock claw, and by adjusting the height of the head of the adjustment screw protruding from the lid member, the final pressing force when closing the opening of the lid member is finely adjusted. Is done.

According to a third aspect of the present invention, a pair of left and right symmetrical mounting brackets are fixed to both left and right sides of the opening of the side wall surface, and a lid member is rotatably supported on one of the pair of mounting brackets. Bracket on the other side, a lock claw bracket on the other,
It is characterized by being connected by the same connecting means.
That is, by attaching the lid member and the lock claw only to the side wall surface and connecting the swinging hook to the lid member, it becomes easy to change the left-right directionality of the lid member locking device on the side wall surface.

The claw locking portion 41 of the swing hook 40 is formed by bending the tip of the sheet metal swing hook 40 inward, and the tip of the lock claw 70 is detachably hooked on the claw locking portion 41. A fulcrum pin 42 connecting the swing hook 40 and the opening / closing lever 30 is installed at a fixed position near the center of the opening / closing lever 30 from the fulcrum pin 32 at the tip of the opening / closing lever 30.

The bracket 60 and the lock claw 70 will be described with reference to FIG. 3. The bracket 60 is composed of a fixed seat portion 61 bolted to a mounting bracket 82 and a main body portion composed of a pair of parallel vertical plates integral with the fixed seat portion 61. 62, a stopper having a stopper plate 63 formed at the inner end of the main body 62. The rear end of the thick plate-shaped lock claw 70 is inserted between a pair of vertical plates of the main body 62, and the support shaft 64 It is rotatably connected. The lock claw 70 reciprocates around the support shaft 64 between the lock release position shown by the solid line in FIG. 3 and the lock position shown by the chain line in FIG. A lock claw 70 is provided between the main body 62 and the lock claw 70.
A spring member for constantly applying a rotational force to the unlocking side, for example, a coil spring 65 is provided. Both ends of the coil spring 65 are locked by the main body 62 and the lock claw 70, and the coil spring 6
5 constantly biases the rear end of the lock claw 70 below the support shaft 64 in the direction of the arrow in FIG. The rear end of the lock claw 70 comes into contact with the stopper plate 63 by the biasing elastic force, and the lock claw 70 is held at the lock release fixed position.

The distal end of the lock claw 70 protrudes from the bracket 60, and a screw pressing end surface 71 is formed inside the right end of FIG. 3 on the right side in FIG. 3, and a hook engaging portion 72 is formed outside the left end of FIG. The screw pressing end surface 71 is a curved surface that presses the top surface of the adjusting screw 28 provided on the lid member 20, and the hook locking portion 72 is detachably hooked on the claw locking portion 41 of the swing hook 40. It is an uneven step surface.

The lock claw 70, the swing hook 40 and the opening / closing lever 30 are arranged so that the cover member 20 is manually opened and closed as shown in FIGS. 4 to 6, and the cover member 20 closes the discharge port 4. Sometimes, to lock the lid member 20 firmly,
The mutual dimensional relationship is determined. FIG. 4 shows a state in which the cover member 20 is partially opened, and the opening / closing lever 30 and the swing hook 40 are located at arbitrary positions with respect to the opened cover member 20. The opened lid member 20 is pushed by hand and pressed against the side wall surface m of the trash can 2b as shown in FIG. 5, and then the opening / closing lever 30 is pulled forward with one hand and rotated in the direction of the lock claw 70 to open and close. When the lever 30 and the swing hook 40 approach the lock hook 70, the hook hook 41 of the tip of the swing hook 40 is manually hooked on the hook hook 72 of the lock hook 70 located at the unlock position, and the lever 30 is held. The opening / closing lever 30 is rotated in the closing direction on the lid member 20 side. The rotation operation of the opening / closing lever 30 in the closing operation direction is a simple manual operation in which the opening / closing lever 30 is pushed toward the dust bin 2b from the near side, and is also a manual operation only at the lateral position of the dust bin 2b. Therefore, the work posture is easy and the work can be performed quickly.

In the state shown in FIG.
Side, the swing hook 40 starts swinging movement in the rotation direction of the opening / closing lever 30 and pushes down while pulling the lock claw 70, and the tip of the lock claw 70 resists the elasticity of the coil spring 65. And rotate it inward. When the opening / closing lever 30 is rotated to a position in the middle of rotation indicated by the solid line in FIG. 6, the tip of the lock claw 70 contacts the head of the adjusting screw 28 of the lid member 20. From this point, the opening / closing lever 30
Is further rotated in the closing operation direction, the swinging hook 40 further pushes down the lock claw 70, and the tip of the lock claw 70 gradually presses the adjustment screw 28 firmly, so that the lid member 20 is moved to the side wall surface of the dust input box. m. Immediately before the opening / closing lever 30 rotates to a lock position where the swing arm 24 is substantially parallel, a straight line connecting the locking point between the lock claw 70 and the swing hook 40 and the fulcrum pin 42 overlaps the position of the fulcrum pin 32,
The pressing force of the adjusting screw 28 by the lock claw 70 becomes maximum. When the pressing force reaches a maximum, the opening / closing lever 30
Is slightly rotated in the closing operation direction, a straight line connecting the locking point between the lock claw 70 and the swing hook 40 and the fulcrum pin 42 passes from the fulcrum pin 32 to the swing arm 24 side, and the open / close lever 30 swings. The self-locking is performed at the lock position abutting on the arm 24, and the swing hook 40 and the lock claw 70 are firmly locked at the lock position indicated by the solid line in FIG.

When the lid member 20 is opened from the trash insertion box 2b, if the opening / closing lever 30 at the lock position is slightly pulled toward the user, the lock is released, and the state shown in FIGS. 6 to 5 is obtained. The swing hook 40 is removed from the claw 70 by hand. This lid opening operation is also a manual operation only on the side of the dust bin 2b, so that it can be easily and quickly performed.

In the closed state of the discharge port shown in FIG.
0 is forcibly pressed against the side wall surface m of the refuse input box 2b by the lock claw 70. This pressing force is given by the principle of leverage when the swing hook 40 swinging by the rotation of the opening / closing lever 30 pushes down the lock claw 70. Therefore, the opening / closing lever 30
The lock claw 70 presses the lid member 20 sufficiently firmly even if the manual rotation operation force of is small. Also, garbage input box 2
Since the final pressing force of the lid member 20 to b can be arbitrarily adjusted with the adjusting screw 28, the following is possible.

As shown in FIGS. 7 and 8, a groove for generating a vacuum is conventionally formed on the sealing surface around the outer surface of the elastic sealing material 25 fixed to the lid body 21 of the lid member 20. In the present invention, as described above, the sectional shape of the sealing surface is increased by increasing the final pressing force so that the convex surface 2 having no vacuum suction effect is formed.
5a. The convex surface 25 a is formed at a height protruding from the opening end of the lid main body 21. FIG.
As shown in (A), when the lid member 20 is brought into contact with the side wall surface m of the trash input box 2b, the convex surface 25a of the sealing material 25 is formed.
Abuts against the side wall surface m. In this state, when the lid member 20 is pressed by the lock claw 70 via the adjusting screw 28, the pressing force at this time crushes the convex surface 25a of the sealing material 25 as shown in FIG. 25 is pressed against the side wall surface m, and the sealing material 25 firmly closes the outlet 4. When the lid member 20 is opened, the convex surface 25a of the sealing material 25 is elastically restored at the stage of starting the opening, and the separation of the sealing material 25 from the side wall surface m is ensured.
Does not have to be detached from the lid body 21.

In particular, as described with reference to FIG.
If the sealing material 25 is embedded and filled with the buried metal fitting 26, the buried metal fitting 26 bites into the sealing material 25, and the sealing material 25 is more firmly fixed inside the lid main body 21.
When the lid is released, there is no need to worry that the sealing material 25 comes off the lid main body 21, and the reliability of opening and closing the lid is improved.

As described with reference to FIG. 9, a pair of left and right symmetrical mounting brackets 81 and 82 are welded to the left and right sides of the discharge port 4 on the side wall surface m of the refuse input box 2b. By selecting one of the brackets 60 and fixing it with the same bolts 83,..., The left-right directionality of the lid member locking device can be arbitrarily selected. For example, the direction of the lid member locking device shown in FIG. 1 can be reversed right and left by 180 degrees, an example of which is shown in FIG. In the lid member locking device of FIG. 10, the bracket 60 is bolted to the right mounting bracket 81 in FIG. 9, and the bracket 50 is bolted to the left mounting bracket 82. The selection of the left and right directions of the lid member locking device is performed so that the lid opening / closing operation can be easily performed in accordance with the type of the dust bin 2b. Also,
Welding the fittings 81 and 82 to the dust box 2b stabilizes the mounting strength, and eliminates the risk of sewage leakage from the metal fitting location of the dust box 2b.

Although the embodiment of the present invention has been described above, the present invention can be variously modified in addition to the above embodiment. For example, the embodiment is a cover member for a sewage tank discharge port of a garbage truck. Although the present invention is applied to a lock device, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a lock device for various lid members that require sealing.

[0034]

According to the first aspect of the present invention, the opening / closing lever for opening and closing the lid, the swinging hook, and the locking claw are provided only on the side wall surface, and these manual operations can be performed only on the side of the trash input box. Therefore, the manual opening and closing operation of the discharge port on the side wall surface becomes simple and convenient.

According to the second aspect of the present invention, the final pressing force when the lid member is pressed against the side wall surface by the lock claw can be finely adjusted by the adjusting screw of the lid member, and the discharge port closing strength of the lid member can be adjusted appropriately. Adjustment is possible.

According to the third aspect of the invention, the right and left directions of the lid member locking device installed on the side wall surface can be arbitrarily and easily selected and changed, so that the design of the lid member locking device in the garbage charging box is free.
