Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a travel bag locking device.

[0002]

[Prior art]

 Generally, when traveling, we carry a luggage that contains necessary items such as daily necessities and clothes, but different luggage, structure and type of luggage are selected and used according to individual needs and preferences. Therefore, it is necessary for the contractor to continuously sell new types of goods according to the transition of the flow from the time of design and development.For example, the large-sized travel bag with a rigid shell used to be manufactured by the injection molding box gradually increases due to the increase in the manufacturing cost and the material cost. It was replaced by a bag, and the price dropped significantly even though it had the same function. However, since this type of injection-molded box-shaped bag is integrally molded of plastic material, it differs from conventional ones, and in addition, it is normally not reinforced by attaching a frame member to the opening edges of both lower housing parts. The design of the thickness and shape of the opening edge is devised so that it can be finished in a single molding process.However, as an accessory of plastic injection molding, the long thin part is cooled and shrunk after injection molding. Since it is easily deformed by stress, the locking device that is mounted across the opening edges of both the upper and lower housing parts is not suitable for the conventional structure where the opening edge is used for a large bag with high rigidity, and there is some deformation. Therefore, the structure must be designed so that it does not come off even if the opening edge does not fit perfectly.

[0003]

[Problems to be solved by the device]

 That is, an object of the present invention is to provide a travel bag lock device which is designed to have a novel structure and which locks by locking the two bag storage parts by injection molding which are pivotally connected so as to be openable and closable.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is fixed to the opening edge of either one of the upper and lower housing parts that are pivotally connected in an openable and closable manner, and the edge of the other opening edge side that faces the one opening edge side. A board having a fixed hook protruding along it; a substantially rectangular recess is formed in the board, a torsion spring is arranged at one edge pivotally connected to the board, and the other edge is separated from the board Is formed at one end of the rotating hook part by pivotally attaching a rotating hook part provided with a torsion spring to a middle part near the rotating end edge of the rotating hook part. When the pressing portion is extended to the outside of the back surface and at the same time the movable hook formed at the other end of the rotating hook portion is positioned in the recessed portion and the rotating edge is pressed toward the substrate, the movable hook is moved. Engage with the fixed hook and further press the pressing portion to release the engagement and allow the turning edge to return to the original position. A rocking seat provided with a lock tool that can hold the engaged state of the movable hook and the fixed hook close to the middle stage part; and a torsion spring arranged at one end pivotally connected to the rocking seat. A latch plate that is hooked on the other end and is driven by the swing seat to rotate in the direction toward the board, and that is hooked to a locking seat projecting on the opening edge of the other accommodation portion. It is configured by combining.

[0005]

[Action]

 According to the present invention configured as described above, when the rocking seat is rotated in the direction in which the rocking seat is superposed on the base plate from the unlocked state, the movable hook of the pivoting hook that is pivotally mounted on the base plate is moved to the base plate. It can be moved so as to come into contact with the outer curved surface of the fixed hook, and the latch plate is laterally interlocked with the surface of the opposite side accommodation part so that the hook at its end engages with the inside of the locking seat of one accommodation part. Can be stopped. Then, when the rocking seat is continuously pressed downward, the entire rotary hook is interlocked and moves downward, and the movable hook of the rotary hook moves along the curved surface of the fixed hook to the outer surface of the fixed hook. When the locking operation is performed, the latch plate pulls the locking seat of the one accommodating part toward the other accommodating part by the lever action that occurs when the swing seat rotates. As a result, the opening edges of the two accommodation parts are in close contact with each other. This completes the locking operation of the travel bag lock device.

Then, when releasing the hooked state of the movable hook and the fixed hook, if the pressing portion of the rotating hook portion is strongly pressed, the entire rotating hook portion rotates about the shaft pin as an axis, and The movable hook rotates along the arc locus and gradually separates from the fixed hook, and finally the hooked state with the fixed hook is released, and the swing seat tries to mutually repel the board. Since the rotational elasticity is accumulated, when the pressure applied to the pressing portion is released, the rocking seat recovers to the unhooked state with the other edge jumping up about the shaft pin.

The above and other objects, features and advantages of the present invention will become more apparent from the detailed description of the embodiments below with reference to the drawings.

[0008]

【Example】

 As shown in FIGS. 1 and 2, the embodiment of the present invention comprises a substrate 1, a swing seat 2 and a latch plate 3 which are pivotally connected to each other in turn; The pair of pivot seats 11 are fixed to the opening edge of one of the accommodating portions 91, 92, and a pair of pivot support seats 11 are formed at appropriate intervals along the ends facing the opening edge of the accommodating portion 91. A swinging seat 2 is pivotally connected, and a fixing hook 12 is provided so as to project along the other end of the substrate 1.

The rocking seat 2 is pivotally installed between both pivotally supporting seats 11 of the base plate 1 by shaft pins 21 around which torsion springs 22 are provided at both lower ends thereof. Rotational hooks 25 are pivotally attached to each other by accumulating the rotationally elastic properties of mutual repulsion, and by a shaft pin 23 around which a torsion spring 24 is provided at an interrupted position facing the upper end side of the swing seat 2 (shown in FIG. 2). As described above, the pressing portion 252 formed at one end of the rotating hook portion 25 is extended to the outside from the back surface of the swing seat 2, and the movable hook 251 formed at the other end of the rotating hook portion 25 is attached. Let it stay inside. The movable hooks 251 can be hooked and engaged with each other corresponding to the fixed hooks 12, and the pressing portion 252 is such that one end of the torsion spring 24 abuts on the rotating hook portion 25. Therefore, when pressed, the rotation hook 251 is released to release the hook locking engagement with the fixed hook 12 as shown in FIG. 5, and at the same time, to provide the elastic force to recover the state shown in FIG. be able to. Further, the rocking seat 2 is provided with a lock tool 27 in the vicinity of the middle part thereof, and the lock tool 27 abuts in a locked state by appropriately rotating a number ring 271 having numbers set therein beforehand. The plate 272 is rotated upward to stop the rotation of the rotating hook portion 25. The locking / unlocking function and the detailed structure belong to the prior art in comparison, and are not the design emphasis of the present invention. So I will omit the joke here.

The latch plate 3 is pivotally attached to a pair of mounting holes 28 provided on both side surfaces of the swing seat 2 through a pair of shaft pins 31 in both left and right shaft supporting holes 32 formed at one end thereof, and Since the torsion spring 33 is provided around the circumference of any one of the shaft pins 31, the latch plate 3 accumulates the elastic force of rotating downward, and at the same time, at the other end of the latch plate 3 which swings downward. The hooks 34 for hooking are formed on the locking seats 921 (as shown in FIG. 2) protruding from the opening edge of the other accommodation portion 92 of the luggage.

With the above-described structure, the swing seat 2 rotates about the shaft pin 21 at the lower end as an axis, and the movable hook 251 of the pivot hook portion 25 pivotally attached to the swing seat 2 is provided on the substrate as shown in FIG. It can be brought into contact with the outer surface of the fixed hook 12 of No. 1. At the same time, the latch plate 3 is also interlocked and moves laterally (to the right in the drawing) so that the hook 34 thereof is locked inside the locking seat 921 of the one accommodation portion 92. Thereafter, when the swing seat 2 is continuously pressed downward, the entire rotary hook portion 25 is interlocked and moves downward, so that the rotary hook 251 of the rotary hook portion 25 moves outside the fixed hook 12. When the movable hook 251 shown in FIG. 4 has already been hooked to the fixed hook 12 by sliding inward from the side surface, and when the hook is fixed, the latch plate 3 is engaged with the one accommodation portion 92. By pulling the stop seat 921 further to the right in the figure, the opening edges of the accommodating portions 91 and 92 come into close relative contact with each other, and the hooking operation of the overall good bag lock device is completed.

When it is desired to release the state where the movable hook 251 is hooked by the fixed hook 12, as shown in FIG. 5, if the pressing portion 252 of the rotating hook portion 25 is strongly pressed, the rotating hook hook 252 is pushed. The entire part 25 rotates about the shaft pin 23, and the movable hook 251 rotates along an arc locus to gradually separate from the fixed hook 12, and finally the hooked state with the fixed hook 12 is released. Further, as described above, since the rocking seat 2 accumulates the rotational resilience for mutually repulsing the substrate 1, as described above, when the pressing on the pressing portion 252 is released, the rocking seat 2 is released. 2 jumps up about the shaft pin 21 and recovers the unhooked state shown in FIG.

[0013]

[Effect of device]

 According to the present invention, when the swing seat is rotated in the direction in which the swing seat rises from the unlocked state to overlap with the board as described above, the turning hook of the turning hook contacts the outer surface of the fixed hook of the board. At the same time, the latch plate can be laterally interlocked and its hook can be locked inside the locking seat of the other accommodating part.If the rocking seat is pressed downward, the whole pivoting hook part is interlocked. The movable hook of the pivoting hook moves downward and slides inward from the outer surface of the fixed hook to be locked, and in the process of this hook stopping operation, the latch plate is opened by the opening edge of the other accommodation portion. Closely abut each other. Further, when it is desired to release the hooked state of the movable hook and the fixed hook, if the pressing portion of the rotating hook portion is strongly pressed, the entire rotating hook portion rotates about the shaft pin as an axis, and When the hook rotates along the arc locus, it gradually separates from the fixed hook, and finally the hooked state with the fixed hook is released, and when the pressure on the pressing portion is released, the rocking seat moves Since the other edge jumps up around the product and recovers to the unhooked state, it has a relatively new structure and can be applied by straddling both the bag storage parts by injection molding.
