Description

[Detailed explanation of the idea] This case relates to a cosmetic compact.

This type of device generally has a body and a lid that are pivotally connected at the rear, and the lid is locked to the body at the front to keep the lid closed.

The present proposal is intended to make it easier to open the lid of such a device.

The illustrated embodiment will be described below.

Figures 1 to 3 are examples of this.
4 is an inner plate fixed in the body 1; 5 is a drum plate housed in the inner plate; 6 is a lid body 2 and an inner plate 4;
The engaging means 7 provided at the front of the body 1 and the inner plate 4
8 is a cam means constructed between the rear part of the actuating plate and the rear part of the lid 2, and 9 is an actuating plate 7 for releasing the engaging means 6. This is a release cam installed at the front of the cam.

The body 1 and the lid 2 have a rectangular planar shape,
It is pivoted 3, 3 on the left and right sides of the rear, and has a horizontally long rectangular window 10 in the center of the rear.

The inner plate 4 has an outward flange 11 on its upper edge, and the flange 11 is fixed to the upper edge of the body 1, and spaces 12 and 13 are formed at least in the front and rear parts between the inner plate 4 and the body 1. The lower part supports the actuating plate 7 so as to be movable back and forth. Also, the flange 1
A notch hole 14 and a through hole 15 are bored in the front and rear portions of 1.

The engagement means 6 includes an engagement protrusion 16 provided in the notch hole 14, and an engagement protrusion 17 that hangs from the front of the lid 2 and engages with the engagement protrusion.

The actuating plate 7 is formed into a rectangular shape whose length is slightly shorter than the depth of the meat 1, and is located at the center of the meat 1 to connect the bottom of the meat and the inner plate 4.
It is disposed in the front-rear direction between the bottom of the inner plate 4 and supported so as to be movable back and forth at the lower part of the inner plate 4, with the front and rear parts located in the spaces 12 and 13, and the rear end 18 in the window 10. It is exposed so that it can be pushed.

The cam means 8 forms an inclined surface 19 facing diagonally upward and forward at the rear of the actuating plate 7, and the inclined surface is movably moved forward in the rear space 13, that is,
It is movably provided adjacent to the pivot parts 3, 3, and a contact 20 is vertically provided in the space from the rear of the lid 2, so that the contact 20 faces the inclined surface 19 through the through hole 15.

The release cam 9 is provided at the front of the actuating plate 7, and has an inclined surface 21 facing obliquely upward and forward, which abuts the lower end of the engagement protrusion 17.

In the figure, 22 is a mirror attached to the inner surface of the lid 2. It is preferable that the above structure is made of synthetic resin.

With the above structure, when the rear end 18 of the actuating plate 7 is pushed in with the illustrated lid 2 closed, the actuating plate 7 moves forward, and the inclined surface 21 of the release cam 9 engages the engagement protrusion 17. At the same time, the inclined surface 19 of the cam means 8 pushes up the contactor 20 and the lid 2 is raised greatly. To specifically explain this rising state using the formula shown in Figure 7, the rising angle θ ₁ is: O: Center point of the pivot joint A: Position of the contact point of action when the lid is closed B: Position of the contact point of action when the lid is open r: Straight line distance from point O to point A and from point O to point B l ; Horizontal distance from point O to point A h ₀ ; Height from point O to point A h ₁ ; Lifting height of the point of action of the contactor pushed up by the inclined surface of the cam θ ₀ ; Straight line from point O to point A and the horizontal line θ: It is given by the angle between the straight line from point O to point B and the horizontal line.

Now, if l = 7mm, h ₀ = h ₁ = 3mm, then As the point of action of the contact rises by 3 mm, the lid 2
rises at a large angle of 33°20′.

If the cam means 8 is at the front of the lid, l=7×12
mm, the rising angle θ ₁ ′ in this case is As a result, the point of application of the contact rises by 3 mm, and the lid rises only at an extremely small angle of 1°80'.

Therefore, when the cam means 8 is on the rear side, compared to when it is on the front side, 33°20'-1°80'=
A large angle of rise of 31゜40′ is produced, 33゜20′÷1゜
80′ = 18.44 times the angle of rise.

In other words, since the cam means 8 is close to the pivot points 3, 3 at the rear of the body 1 and the lid 2, the cam means can move the lid 2 to a very large extent with a slight movement of the cam means, following the principle of leverage. It can be raised.

In this way, the lid 2 rises significantly, so after that, it is only necessary to push the lid 2 further open.

Note that the cosmetics are stored in the drum 5.

Next, FIGS. 4 to 6 show another example. In this case, in the previous example, the rear window 10 is provided at the center of the front of the body 1, and the front end 2 of the actuating plate 7 is
3 is exposed in the window 10, and the inclined surface 19 of the cam means 8 faces obliquely upward and rearward.

In addition, the engaging means 6 is not provided with the engaging protrusion 16 on the inner plate 4 as in the previous example, but with the engaging protrusion 24 erected at the front part of the actuating plate 7, and this is attached to the lid 2. A pair of elastic pieces 25, 25 are provided protrudingly on the left and right sides of the engaging protrusion 24, and the tips of the elastic pieces are supported on the inner plate 4, Both engaging protrusions 17 and 24 are brought into engagement by the elasticity of the elastic piece.

In this case, when the illustrated lid 2 is closed, the front end of the actuating plate 7 is pushed in to release the engagement of the locking means 6 and the cam means 8.
In this case, the elastic pieces 25, 25 act to push the actuating plate 7, and the actuating plate 7 resists the elastic pieces 25, 25. It is pushed in and returned by the elasticity of the elastic piece. Further, in the locking means 6, when the actuating plate 7 is pushed, the engaging protrusion 24 of the actuating plate is separated from the engaging protruding piece 17 of the lid 2.

According to the present invention, the entire actuating plate 7 can be pressed and slid directly in the longitudinal direction of the material by pressing with a finger, and therefore, the actuating plate 7 can be pressed and slid smoothly and reliably without any inconveniences such as bending, skewing, or stiffness. By pushing the operating plate 7, the engagement means 6 is disengaged and the rear cam means 8 is moved.
, the lid 2 can be raised greatly, and the raising is achieved by providing the cam means 8 between the rear part of the actuating plate 7 and the rear part of the lid 2 and placing it close to the pivot parts 3, 3, so that the cam means 8 can be raised by a small amount. Regardless of the movement, the lever will cause an extremely large movement, making opening the lid extremely easy. In addition, there is no strong shock when opening the lid, and the contents do not accidentally pop out.
Moreover, the engagement can be performed strongly and natural opening due to external force can be prevented.

It is simple in structure and production, can be provided at low cost, and is extremely useful in practice.
