Description

[Detailed Description of the Invention] [Industrial Application] The present invention relates to a compact device, and particularly to one provided with a locking mechanism for opening and closing the lid.

[Conventional technology]

Various types of compacts have been proposed in the past, such as the
What is shown in the 93309 publication (FIGS. 5 to 7) has a lid 32 connected to a main body 30 via a hinge portion 31, and a lid 32 that is protruded from the main body 30. A locking device 34 is provided for locking or releasing the engagement with the engaging pawl 33.

A slide member 35 is slidably arranged at the bottom of the main body 1, and the engagement claw 3 is provided at one end of the slide member 35.
A hook-shaped engaging portion 36 that engages with the lid body 32 is formed in a protruding manner, and a hook 37 that engages with the vicinity of the hinge portion of the lid body 32 and biases it in the opening direction is formed on the other end side. Arm portions 38 extend diagonally on both sides of the slide member 35, and push buttons 39 are provided at the ends of the arm portions 38, respectively. This arm portion 38 is connected to the slide member 3
5 and the push button 39 are bendable hinges.

The push buttons 39 are disposed flush with the left and right side walls of the main body 30, and when pushed from the left and right, the arm portions 38 are bent, causing the slide member 35 to slide.

As a result, the engagement between the engaging claw 33 and the hook-shaped engaging portion 36 is released, and the hook 37 urges the lid 32 in the opening direction, so that the lid 32 is completely opened.

In this way, the force applied to the push button 39 releases the engagement between the engagement claw 33 and the hook-shaped engagement portion 36, and forces the lid 32 into the open state.

[The problem that the idea aims to solve]

However, with the above-described configuration, a considerable pressing force must be applied to each push button when opening the lid, resulting in a lack of operability. That is, when pushing up the lid 32, it is necessary to open the lid by a small amount of sliding of the slide member 35, so by making the distance between the contact point of the hook 37 and the hinge part 31 and the hinge shaft closer, the lid can be opened by a small sliding amount. There is no choice but to earn 32 rotation strokes. For this reason, it is necessary to slide the slide member 35 with a considerable force, but due to the structure, the pressing force in the right angle direction to the push button 39 can be divided into one in the same direction as the advancing direction of the push button 39, and one in the direction perpendicular to this. Therefore, sufficient stress cannot be applied to the slide member 35 unless a strong pressing force is applied.

Further, since a strong lateral moment is applied to the push button 39, it is likely to rattle, and friction between the side surface of the push button 39 and the main body 30 causes smooth operation.

From the above points, it is difficult to open the lid with one hand, and there are problems such as having to assist in opening the lid with the other hand.

The present invention was created in view of the above points, and allows the lid to be opened easily and smoothly with one hand.
In addition, the technical challenge is to eliminate the need to place large buttons on the outside of the compact, thereby reducing design constraints.

[Means for solving problems]

In order to solve the above-mentioned technical problem, the present invention connects the lid 2 and the main body 1 by a hinge part 3 so as to be openable and closable, and a locking pawl 2a protruding from the lid 2 side.
The following technical measures were taken in a compact equipped with a locking device 6 for locking or unlocking.

That is, the hinge portion 3 is provided with an elastic member 4 for always urging the lid body 2 in the open direction. As this elastic member, a coil torsion spring, a plate spring, or a synthetic resin elastic body can be used. On the other hand, on the main body 1 side, a through hole 5 penetrating to the outside of the main body is bored, and a slide member 7 is arranged so as to cover this through hole 5. This slide member 7
slides in a direction perpendicular to the hinge axis 8,
It is adapted to lock or release the lid 2. An engaging member 10 that engages with the locking pawl 2a is formed on one end side of the slide member 7, and the engagement between the locking pawl 2a and the engaging portion 10 is shallow, and the mutual contact surfaces are tapered, and a pressed surface 11 that is pressed by the hinge portion 3 when the lid body 2 is opened is formed on the other end side, and engaging holes 12 are formed at positions corresponding to the through holes 5, respectively. Form. A locking button portion 13 that penetrates from the inside of the body toward the outside of the body is inserted into the engagement hole 12 and the through hole 5, and the locking button portion 13 is inserted into the engagement hole 12 and the through hole 5.
2 is made compact by forming the locking button part 13 into a shape that can be released from engagement with the locking button part 13 by pressing the locking button part 13 from the outside.

[Effect]

When the locking button part 13 is pressed from outside the main body 1, the locking button part 13 and the slide member 7 are disengaged. Therefore, the engaging portion 10 formed on the slide member 7 is pressed by the locking pawl 2a. Here, the engagement between the engagement claw 2a and the engagement portion 10 is shallow, and the mutual contact surfaces are tapered, so the slide member 7
The whole unit retreats toward the hinge shaft 8 and becomes an open state. When the lid is opened, the pressed surface 11 is pressed, and the slide member 7 returns to its original position, and the locking button portion 13 and the slide member 7 engage again, so that the lid can be closed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

This compact has a main body 1 and a lid 2 engaged with each other via a hinge portion 3 so as to be openable and closable, and is similar to the conventional compact in this respect. A locking pawl 2a is formed on the lid body 2, and a locking device 6 is provided on the main body 1 side for locking or releasing the engagement with the locking pawl 2a.

A coil torsion spring 4 is provided as an elastic member on the hinge portion 3, and is adapted to always bias the lid body 2 in the opening direction. A through hole 5 penetrating to the outside of the main body is bored in the bottom surface of the main body 1, and a slide member 7 is arranged so as to cover this through hole 5. This slide member 7 is adapted to slide in a direction F perpendicular to the hinge axis 8, and is arranged so as to move along a rail groove 9 formed on the bottom surface of the main body 1. This slide member 7
is formed into a long plate shape, and an engaging portion 10 that engages with the engaging claw 2a is formed at one end in the longitudinal direction, and an engaging portion 10 that engages with the engaging claw 2a is formed at the other end, and the hinge portion 3 engages with the engaging claw 2a when the lid body 2 is opened. A pressed surface 11 to be pressed is formed. Furthermore, the slide member 7 is provided with a substantially “L”-shaped engagement hole 12 at a position corresponding to the through hole 5.
A locking button portion 13 is inserted into the engagement hole 12 and the through hole 5. This locking button part 13
A push button piece 15 is provided vertically on the flange 14 for preventing extraction,
A locking step 16 is formed at the base thereof, and when the locking step 16 is inserted into the engagement hole 12 up to the base, the locking step 16 engages with a corner 17 of the engagement hole 12. There is.

Therefore, when the locking button portion 13 is in the above-described state, the slide member 7 is locked to the main body 1. On the other hand, the push button piece 15 is slightly exposed from the bottom surface of the main body 1, and when pressed, the entire locking button part 13 moves upward and the engagement between the locking step 16 and the corner part 17 is released. The slide member 7 is then in a state in which it can slide along the guide portion 18 of the engagement hole 12 in a direction perpendicular to the hinge shaft 8. A placing plate 19 for placing cosmetics, etc. is provided above the slide member 7, and this placing plate 1
A housing chamber 20 for housing the locking button portion 13 is formed on the lower surface of the housing 9 . The locking button part 13 is housed in the housing chamber 20 via a leaf spring 21, and the locking button part 13 is pressed downward by the leaf spring 21.

Note that the mounting plate 19 is provided with a passage hole 22 through which the engaging claw 2a passes. A pressing portion 23 is formed at the lower end of the hinge portion 3 and projects when the lid is opened, and is configured to press the pressed surface 11 and push the slide member 7 back to its original position when the lid is opened.

An example of operation in such a configuration is as follows:
First, when the push button piece 15 is pressed when opening the lid, the entire locking button portion 13 moves upward, and the engagement between the locking step 16 and the corner portion 17 is released. Since the engagement between the engagement claw 2a and the engagement portion 10 is shallow, and their mutual contact surfaces are tapered, the slide member 7 receives the opening force from the coiled torsion spring 4 and closes the hinge portion 3. It is moved back to the side and the lid is opened. After the lid is opened, the pressing portion 23 presses the pressed surface 11 to advance the slide member 7 to the position before opening the lid. Therefore, the locking stage 16 is fitted into each part 17 again, and the slide member 7 is locked in its original position.

When the lid is opened, when the lid body 2 is moved downward, the engaging claw 2a engages with the engaging portion 10, and the lid is closed.

Although an example has been described above in which the slide members 7 are arranged in the central part of the main body 1, they may be arranged in a part offset from the center as shown in FIG. FIG. 4 shows another embodiment, in which the engagement hole 12 is formed in a potbellied hole shape, and the locking button portion 13 is formed by coaxially stacking cylinders of different diameters.
The engagement is made to be released.

Although an example has been described in which a coiled torsion spring is used as the elastic member, the present invention is not limited to this, and it is of course possible to use an elastic body such as a plate spring or synthetic resin.

[Effect of idea]

According to the present invention, the hinge part is provided with an elastic member for always biasing the lid body in the opening direction, and the engaging claw provided on the lid body side is released by sliding the sliding member, and this slide The operation is activated by pressing the locking button, and since the engagement between the locking pawl 2a and the engaging portion 10 is shallow, and the mutual contact surfaces are tapered, the locking button can be pressed slightly. The lid can be opened just by pressing with sufficient force.

Furthermore, since the locking button section is activated by pressing with a slight force, the pressing portion of the locking button section 13 can be downsized, and the degree of freedom in design can be increased.

In addition, when opening the lid, the sliding member 7 is moved by the hinge part 3.
Since the lid can be pushed back and reset to its original position, it can be reliably locked when closing the lid.
