Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a juicer for squeezing juice from vegetables, fruits, etc. at home.

(Prior art) Regarding this type of conventional regulator,
This will be explained with reference to FIG. 11, taking Publication No. 25598 as an example.

In the same figure, the conventional juicer has a main body 1,
It consists of a container 2 mounted on a main body 1 and a lid 3 thereof. Fixing plates 4 having engaging hooks 4a on both sides of the main body 1 are rotatably attached so that the left and right sides interlock with each other, and each of the engaging hooks 4a connects to the lower end of the lid 3. The container 2 and the lid 3 are engaged with the engagement protrusions 3a formed on both sides and mounted on the main body 1.
It has a structure in which it is fixed to the main body 1.

(Problems to be Solved by the Invention) However, in the above configuration, after the container 2 and the lid 3 are placed on the main body 1, the fixing plate 4 is operated and the engaging hook portion 4a is attached to the lid 3. It is necessary to engage the engaging protrusion 3a, and two operations are required: placing the container 2 on and closing the lid 3, and operating the fixing plate 4 to fix the lid 3, and also removing the container 2. At the same time, two operations were required: removing the fixing plate 4 and lowering the container 2, resulting in a problem that the operation was complicated and troublesome.

Furthermore, since the fixing plate 4 is provided on the outside of the main body 1, the width becomes wide and the appearance becomes complicated, making it difficult to miniaturize.

The present invention solves the above-mentioned problems and provides a compact juicer with a simple appearance, in which the container and lid can be attached and detached in one operation.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides engaging holes in the extension parts of the lower ends of both sides of the lid, and protrudes from both sides of the main body, and provides the above-mentioned A built-in clamp is always biased in both directions by a spring, and has an engaging protrusion that fits into the engaging hole of the clamp.
Furthermore, the protruding surface of the engagement protrusion forms an obliquely upward cam surface. Furthermore, a sloped rib with a lower lower part is formed below the engagement protrusion toward the inner wall surface of the main body. Furthermore, it rotates about a shaft fixed within the main body as a fulcrum, and the tips of the left and right arms move up and down while contacting the above-mentioned inclined ribs. An operating arm is provided that is integrally formed and has left and right arms of different lengths, and when the left and right operating arms are rotated, the tip of the longer arm is placed before the tip of the shorter arm. It is made to touch the above-mentioned inclined rib.

(Function) With the above configuration, when the container and lid are sequentially mounted on the main body and the lid is pressed down, the extension of the lid hits the cam surface of the engagement protrusion of the clamp, and as it slides down the cam surface, Push the engaging protrusion inward against the spring. Furthermore, press down on the lid to open the engagement hole.
When the clamp is aligned with the engagement protrusion, the clamp is urged outward by the spring, so the engagement protrusion fits into the engagement hole, and the lid is fixed to the main body.

When the actuating plate is pushed up by operating it from the outside, the actuating plate moves up the inclined rib of the clamp and pushes the clamp inward against the biasing force of the spring.
The engagement protrusion comes out of the engagement hole of the inner lid. At this time, the resistance force that causes the tip of the operating arm to climb up the inclined rib while tilting the spring-biased clamp inward is as follows:
Although the left and right sides are equal, the longer arm will load a larger couple than the shorter arm, and by taking advantage of the deflection in advance, the clamp can be pushed inward at the same time.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 1 is a cross-sectional view of a regulator according to the present invention, in which the regulator is connected to a main body 1 to which an electric motor 8 is mounted via a buffer body 7, using a bottom plate 5 and screws 6, and to the rotating shaft of the electric motor 8.

Further, a push rod 13 for pressing loaded vegetables, fruits, etc. onto the cutter 10 is slidably fitted into the material input port 3b of the lid 3. Further, as shown in the perspective view of FIG. 2, the container 2 is provided with a juice outlet 2a at one corner of the bottom, and a third
As shown in the bottom view of the figure, a leaf spring 14 is installed in rectangular spring housing recesses 2b formed on both sides.

Returning to FIG. 1, there are containers 2 on both sides of the upper part of the main body 1.
The protrusion 1 that the leaf spring 14 comes into contact with when placed on the
a is provided, and when the lid 3 is fixed to the main body 1, the above-mentioned protrusion 1a is in a state where the leaf spring 14a is bent, as shown in FIG.

As shown in FIG. 2, the lid 3 has downwardly extending portions 3c formed on both sides, and an engagement hole 3d provided at the tip thereof.

As shown in FIG. 1, the main body 1 has clamps 16 on both sides thereof that are biased outwardly by compression coil springs 15 and are supported by fixing anvils 5b formed on the bottom surface of the bottom plate 5. Has been installed. The upper end of the clamp 16 protrudes from the main body 1 and fits into the engagement hole 3d of the lid 3 described above.
Engagement protrusion 16a having a cam surface whose upper surface faces upward
An inclined rib 16b having a low lower end is formed at the upper part of the inner wall side of the main body. Furthermore, tip portions 17a and 17b of the actuating arms 17 are disposed between the clamps 16 disposed on the left and right sides of the main body 1 and the inner wall of the main body 1.

5 and 6 are perspective views and side sectional views showing the relationship between the clamp 16 and the operating arm 17, and FIG. 7 is an overhead view showing the shape of the operating arm 17.

As shown in FIG. 5, the main body 1 has a recess formed on the right side in which a gift-receiving container (not shown) is placed, so that the operating knob 18 protruding from the front of the left convex portion of the main body 1 is fixed. The operating arm 17 is formed with a short arm 17c and a long arm 17d having tip portions 17a and 17b for operating the inclined rib 16b of the clamp 16 on the left and right sides, respectively. The operating arm 17 is also rotatably supported on a support shaft 20 fixed to the main body 1 with a screw 19, and has a positioning projection 17c formed at the base of the short arm 17c as shown in FIG. It is biased counterclockwise by a compression coil spring 21 disposed between the main body 1 and the ceiling surface. Note that the operating arm 17 is held in a substantially horizontal steady position by the main body 1, the operating knob 18, and the compression coil spring 21.
The overhead view of the operating arm 17 in FIG. 7 shows the left and right short arms 1.
7c and an actuating arm 17 with a long arm 17d.

Returning to FIG. 2, the operating arm 17 is placed on the pressure front of the main body 1.
The operation knob 18 and the engagement protrusion 16a of the clamp 16 protrude from the side surface of the upper seal portion.

The operation of the juicer having such a configuration will be explained. First, as shown in Figure 1, the main body 1
After placing the container 2 thereon, the centrifugal separation cage 11 equipped with the comb-shaped filter 12 is fitted onto the output shaft 9.

Next, the lid 3 is fitted to the inner periphery of the container 2, and the extension part 3c is fitted to both sides of the main body 1, so that the tip of the extension part 3c is inserted into the main body 1. It hits the inclined cam surface of the engagement protrusion 16a protruding from 1. Subsequently, when the lid 3 is pushed down, the extension part 3c pushes the engagement protrusion 16a to the surface of the main body 1 against the biasing force of the compression coil spring 15, rides on this, and at the same time, as shown in FIG. , the leaf spring 14 of the container 2 is supported by the protrusion 1a of the main body 1. When the lid 3 is subsequently pushed down, the leaf spring 14 is bent and the container 2 is pushed down, and at the same time the extension 3c is lowered and the engagement hole 3 is lowered.
When d coincides with the engagement protrusion 16a, the engagement protrusion 16a falls under the force of the compression coil spring 15, resulting in the state shown in FIG. 1, and the lid 3 is fixed to the main body 1.

In this way, the lid 3 can be fixed to the main body 1 by attaching the lid 3 to the main body 1 and pushing it down. At this time, the leaf spring 14 housed in the container 2 is bent by the protrusion 1a of the main body 1, and an upward biasing force is generated.

Next, when removing the lid 3, push down the operating knob 18 provided at the front of the main body 1, and as shown in FIG.
is rotated counterclockwise about the support shaft 20 as a fulcrum, and the tip 17a of the actuating arm 17 rides on the inclined rib 16b of the clamp 16, resisting the biasing force of the compression coil spring 15. The clamp 16 supported by the fixing anvil 5b of the bottom plate 5 is tilted inward. At this time, when lifting the clamp 16 onto the inclined rib 16b, the loads applied to the tips 17a and 17b are equal, but the force couple on the long arm 17d is larger than the couple on the short arm 17c, and therefore the deflection that occurs It's also big. However, the long arm 17d
The tip 17b of the short arm 17c is the tip 17a of the short arm 17c.
Since it is formed so as to hit the inclined rib 16b earlier, the deflection is absorbed and the left and right clamps 1
6 fall inward at the same time, and therefore, the left and right engaging protrusions 16a simultaneously come out of the left and right engaging holes 3d of the lid 3.

In this way, when the engagement protrusion 16a of the clamp 16 is removed from the engagement hole 3d of the lid 3, the leaf spring 14
The container 2 and lid 3, which are urged upward by the
It rides on the inner wall of the building, resulting in the situation shown in FIG.
Even if the user releases the operating knob 18 in this state, the engaging protrusion 16a does not fit into the engaging hole 3d, so the lid 3 can be easily removed.

In this way, since the actuating arm 17 is formed such that the tip end 17b of the long arm 17d first contacts the inclined rib 16b, the engaging protrusions 1 provided on the left and right sides
6a is synchronously disengaged from the engagement hole 3d, and the operation for removing the lid 3 is performed smoothly.

Furthermore, since the clamp 16 is built into the main body 1 and fixes the lid 3 from the inside, there are fewer parts that protrude to the outside of the main body 1, and the size of the parts can be reduced.This not only makes the Jusa smaller, but also saves storage space. It also requires less. Furthermore, since there are no parts that protrude outward, there is no chance of the product getting caught on clothing or the like during use.

(Effects of the Invention) As explained above, according to the present invention, the lid is provided with engagement holes in the left and right extensions, and the left and right portions inside the main body are provided with engagement holes that protrude from the main body and fit into the above-mentioned engagement holes. An engaging protrusion that locks the lid, and a lower sloped rib facing the inner wall of the main body are formed at the bottom of the engaging protrusion, and a clamp biased outwardly by a spring is arranged, and a clamp is provided between the left and right clamps and the inner wall of the main body. The actuating arm is integrally formed so that the tip of the actuating arm rotatably supported by the main body moves up and down while contacting the above-mentioned inclined rib, and the long tip of the actuating arm is provided. is formed so that it hits first from the tip of the short arm.

Therefore, when putting a lid on the main body, the lid can be fixed to the main body by sequentially attaching the container and the lid to the main body, and then pushing down the lid in one operation. In addition, when removing the lid, by pressing down on the operating knob, the operating arm, which has the tip of the long arm touching first, absorbs the difference in deflection from the short arm, and synchronizes to open the lid's engagement hole. Since the engaging protrusion of the clamp is pulled out from the clamp, it can be removed smoothly.

Furthermore, since there is no external fixing plate, a compact jacket with a beautiful appearance and no risk of catching clothes etc. can be obtained.
