Description

[Detailed description of the invention] The invention includes a support arm for a squeeze container that holds fruits, etc., and a bracket above the support arm, which is mounted on a support that is erected on a mounting plate.
A vertically movable screw shaft equipped with a squeezing plate that corresponds to the squeeze container is inserted into the bracket, and a pinion that is engaged with the thread of the screw shaft is mounted on the bracket, and one end of the pinion shaft that protrudes outside of the bracket is inserted into the bracket. Move the handle lever, which is attached so that it can swing back and forth, up and down, rotate the pinion shaft and pinion, and rapidly descend until the squeeze plate comes into contact with the fruit, etc., then move the handle lever in one direction, front and back. A two-stage switch that swings to make the pinion and pinion shaft unrotatable, then rotates the screw shaft to lower it gradually and forcefully, and uses a squeezing plate to crush fruits, etc. and squeeze the juice. This invention relates to a manually operated juicer, and its purpose is to provide a manual juicer that can effectively squeeze fruit juice, vegetable juice, etc.

An embodiment of the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a mounting plate on which the receiver a can be freely removed, and a support arm 2 is erected on the rear side thereof, and a support arm 3 of the squeezing container and a bracket 5 above the support arm 3 are attached to the support arm 2.

The support arm 3 has a horseshoe shape when viewed from above, has a stopper protrusion 4 protruding from each front end, and has a bottom plate 35 which is funnel-shaped and has concentric multiple protruding rings 36 and a number of holes 37 inside. The flange plates 33 of both wings of the squeeze container 31, which is placed on the dashed line 32, are placed on the upper surface and are locked by the stopper protrusion 4 so as not to move in the horizontal direction. It is made to face upward.

The bracket 5 is provided with a through hole 6 through which the screw shaft 13 can freely move up and down, a device hole 7 for the pinion 14 that engages with the screw of the screw shaft 13, and a support hole 8 for the pinion shaft 15 that fixes the pinion 14. A fixed clutch 9 with engaging teeth 10 protruding around the support hole 8 and a spring-fitting recess 11 on the inner periphery of the retaining teeth 10 are provided on the outside of the pinion shaft 15 from which one end protrudes.

A squeezing plate 16 that enters from the upper opening of the squeezing container 31 is attached to the lower end of the screw shaft 13 so as to be rotatable in the horizontal direction or fixedly, and a handle 17 is attached to the upper end.

A movable clutch 19 that engages a pin 18 protruding from the outer periphery of the shaft 15 with a sliding groove 20 to restrain relative rotation is slidably fitted into the protruding portion of the pinion shaft 15 from the bracket 5. The clutch 19 is provided with engagement teeth 21 that fit between the retaining teeth 10 of the fixed clutch 9 and a spring hook recess 22 on the inner circumference of the engagement teeth 21. In addition, both ends of a spring 23 loosely wound around the pinion shaft 15 are applied to separate the movable clutch 19 from the fixed clutch 9, and a handle lever 25 is attached to the tip end of the pinion shaft 15, which is capable of swinging from side to side. The base is attached using the pin shaft 24.

At the base of the handle lever 25 are cam surfaces 27 and 28 that alternately come into pressure contact with the outer end surface of the movable clutch 19 by swinging left and right.
The cam surface 28 is shaped like a cam 26 formed with a pin shaft 24.
When the cam surface 28 is brought into pressure contact with the movable clutch 19 by swinging the handle lever 25 left and right, the clutch is pushed in a direction against the elasticity of the spring 23 and engaged with the fixed clutch 9. As a result, the pinion shaft 15 and pinion 14 are restrained from rotating.

To explain the operation of the juicer of the present invention, the handle lever 25 is swung to the left with the screw shaft 13 moved upward as shown in FIG. Then, the clutch 19 is released from the fixed clutch 9 forming the outer surface of the bracket 5 by the elasticity of the spring 23 as shown in FIG. 4, leaving the pinion shaft 15 and the pinion 14 free to rotate. 15 in the direction of the arrow X in FIG.
5 Pressure is applied by contacting the fruit etc. stored on the top to squeeze out most of the fruit juice.

Here, when the handle lever 25 is swung to the right around the pin shaft 24 and the cam surface 28 is brought into pressure contact with the outer end surface of the movable clutch 19, the clutch 19 is pushed by the elasticity of the spring 23 and becomes as shown in FIG. As shown, the locking clutch 9 is engaged to fix the pinion shaft 15 and pinion 14 to the bracket 5.

Therefore, the screw shaft 13 is rotated by the handle 17, and screwed downward while rotating according to the lead of the screw of the screw shaft 13 that engages with the pinion 14 which is not rotatable, and the fruit etc. are relatively squeezed by the squeezing plate 16. Squeeze with high pressure and slow speed.

In the present invention, the fixed clutch 9 is integrated with the bracket 5.
It is not always necessary to provide the movable clutch 19 on the pinion shaft 15, and the cam surface 28 of the cam 26 is pressed directly against the outer surface of the bracket 5 as the handle lever 25 swings in either the left or right direction. and pinion shaft 1
5 may be made non-rotatable.

Also, the cam surface 28 or the movable clutch 19 is connected to the bracket 5.
A friction clutch method may also be used which applies pressure to the shaft in a timely manner.

As clarified from the above explanation, the present invention provides a handle lever 2 that rotates the pinion 14 and the pinion shaft 15.
5 is swung in one direction left and right, the cam surface 28 is pressed against the outer surface of the bracket 5, and the pinion 14 and the pinion shaft 1 are
5 and 5 in a timely manner so that the screw shaft 13 acts as a rack by rotating the pinion 14 to press the squeeze plate 16 etc. against the fruit in the squeeze container 31, and the pinion shaft 15 etc. By fixing the pinion 14, the pinion 14 is converted to the action of a fixed worm or a part of a nut, and the screw of the screw shaft 13 that engages with the pinion 14 is converted into a conveying piece that screws, and by this conveying, fruits etc. are strongly compressed. The juicer can evenly squeeze fruit juice, vegetable juice, etc., and can improve the squeezing function of the screw shaft of the juicer.
