Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a plastic case consisting of a main body and a lid body connected by a hinge, and having a handle and a locking mechanism on the main body side.

Prior Art In the conventional plastic case described above, as shown in FIG. 7, the handle a and the locking mechanism b are independent from each other. Further, as shown in the figure, the locking mechanism b protrudes from the upper outer surface of the case.

Problems to be Solved by the Invention In the conventional example described above, the handle a and the locking mechanism b had to be attached separately, making the assembly work complicated. Furthermore, since the locking mechanism b protrudes from the outer surface of the case, the external appearance becomes poor and the protruding locking mechanism b becomes an obstacle.

Means for Solving the Problems The present invention was developed in consideration of the above-mentioned problems, and it is possible to reduce the number of steps required for assembling the handle, locking mechanism, and locking mechanism to the main body, thereby simplifying the assembly work with the main body. The object of the present invention is to provide a plastic case that can improve the external shape since the locking mechanism does not protrude from the top surface of the main body.
The main body and the lid, which have a double structure, are connected by a hinge at the lower side of each, and a handle is provided on the upper side of the main body, and a lock that removably engages with a locking protrusion protruding from the lid side. A plastic case having a mechanism, a handle is provided on the upper surface of a plate-shaped pedestal, a locking mechanism is protruded from the lower surface of the pedestal, and a pedestal to which the pedestal is fixed to the upper surface of the upper side of the main body. In addition to providing a mounting surface, a hole for the locking mechanism into which the locking mechanism fits is provided on the pedestal mounting surface, and a hole for a locking protrusion corresponding to the locking mechanism is provided on the mating surface of the main body. The pedestal is fixed to the lid body, and a locking protrusion protruding from the mating surface corresponds to the locking protrusion hole on the main body side.

Function By fixing the pedestal to the pedestal mounting surface of the main body, the locking mechanism protruding from the lower surface of the pedestal is inserted into the hollow wall of the main body. The locking part of this locking mechanism faces the locking protrusion hole provided on the mating surface of the main body, and the locking protrusion on the lid side connects from this locking protrusion hole to the locking part of the locking mechanism. engaged.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 6.

In the figure, 1 is a main body, and 2 is a lid, each of which is molded from plastic to have a hollow double-wall structure, and these two members are connected by a hinge portion (not shown) at opposing lower edges. Reference numeral 3 denotes a handle device attached to the upper surface of the main body 1, and the handle device 3 includes a pedestal 4, a handle 5 rotatably provided in the middle of the pedestal 4 in the longitudinal direction, and a handle 5 on both sides of the pedestal 4 in the longitudinal direction. It consists of a locking mechanism 6 provided at the pedestal 4 and a locking mechanism 7 provided at the intermediate portion of the pedestal 4.

The pedestal 4 of the handle device 3 is formed into a plate shape by plastic molding, and its entire periphery is bent downward to form a shallow U-shape in cross section. The handle 5 is rotatably connected to two brackets 8, 8 projecting from the base 5.

The locking mechanism 6 includes a case 9 integrally molded on the lower side of the pedestal 4, a sliding piece 10 that slidably fits into the case 9, and a spring 11 that biases the sliding piece 10 in one direction. A knob 13 that moves along an elongated hole 12 provided in the pedestal 4 is protruded from the upper surface of the sliding piece 10. Hole 1 on the side of sliding piece 10
4 is open, and a locking step 15 is provided at the back of this hole 14 and on the side facing the spring 11. Further, the side surface of the hole 14 on the side of the locking step 15 is a slope 14a that is wider at the opening end side. A hole 16 facing the locking hole 14 is provided on the side surface of the case 9.

The locking mechanism 7 is composed of a hook 17 rotatably supported on the underside of the pedestal 4, and this hook 17 can be rotated by a lock inserted through a lock hole 18 provided in the pedestal 4. There is.

A plurality of fixing protrusions 19 are provided on the lower surface of the pedestal 4, and the pedestal 4 is adapted to be fixed to a pedestal mounting surface 20 formed on the upper surface of the main body 1.

The pedestal mounting part of the main body 1 is hollow,
The pedestal mounting surface 20 is provided with a groove 21 into which the bent portion of the periphery of the pedestal 4 fits, and the pedestal mounting surface 20 is provided with a locking mechanism hole 22 into which the case 9 of the locking mechanism 6 is fitted. However, a locking mechanism hole 23 into which the locking mechanism 7 fits, and a fixing hole 24 into which the fixing projection 19 fits are provided. Furthermore, a locking protrusion hole 25 corresponding to the locking mechanism hole 22 and a locking hook hole 26 are opened in the upper mating surface of the main body 1.

On the other hand, a locking protrusion 2 that engages with a locking step 15 of a sliding piece 10 of a locking mechanism 6 is provided on the upper mating surface of the lid body 2.
7 is provided in a protruding manner at a position corresponding to the locking mechanism 6. Further, at a position facing the locking mechanism 7, an engaging member 28 with which the hook 17 of the locking mechanism 7 engages is provided.

In the above configuration, the handle device 3 and the main body 1 are connected by attaching the pedestal 4 to the pedestal mounting surface 20. At this time, the peripheral edge of the pedestal 4 is fitted into the groove 21 provided on the pedestal mounting surface 20 and positioned, and the locking mechanism 6 protruding from the lower surface of the pedestal 4 is locked into the locking mechanism hole 22. The mechanism 7 is fitted into the locking mechanism hole 23, and the fixing protrusion 19 is fitted into the fixing hole 24, respectively. Then, the main body 1 is fixed by screwing the screw 29 into the fixing protrusion 19 from inside the main body 1.

When the lid 2 is closed in the above state, the locking protrusion 27 of the lid 2 comes into contact with the slope 14a of the hole 14 of the sliding piece 10 of the locking mechanism 6, and the sliding piece 10 is pushed against the spring 11. It is inserted while being moved, and the locking protrusion 27 engages with the locking step 15 of the sliding piece 10 at the end thereof, so that the lid body 2 is locked to the main body 1 in a closed state.

The locking state is released by moving the sliding piece 27 against the spring 11 using the knob 13 and removing the locking step 15 from the locking piece 27.

In the locked state, the hook 17 of the locking mechanism 7 is rotated and engaged with the engaging member 28 on the lid 2 side, thereby locking the lid.

Effects of the invention According to the invention, since the handle 5, the locking mechanism 6, and the locking mechanism 7 are assembled into a unit lock, it is possible to reduce the number of steps required for assembling each of the above-mentioned mechanisms to the main body 1. The assembly work can be simplified. Furthermore, the locking mechanism 6 is connected to the main body 1.
This eliminates the possibility of protruding from the top surface of the holder and improves the external appearance.
