The present invention relates to a back grind device for the purpose of easily removing a portion of the neck ox hands, that is, the back waist portion by a mechanical device. Conventionally, for this purpose, in order to remove the back of the back waist, the wheat groats, which have been sandwiched with the wheat groats at one end of the guards, have been developed in many types, but all of them are inconveniences that must be dependent on manpower and the hassle of carrying them every day. In addition, it was previously known in Japanese Patent Publication No. 45-23,986 that it was possible to remove the back waist part by the up and down movement between the crankshaft and the operation by the crankshaft connected to the motor. As it was to be raised and lowered only up and down, the left and right parts of the back waist could not be removed evenly and there was a defect that the wheat buckwheat could not work as it adhered to the back part.

The present invention focuses on the above-described drawbacks as described above, and uses the electric device by the crank to make the intermittent movement up, down, left and right, so that a person sits in a chair installed in front of the tumbler and switches the switch. ON "to simply and evenly remove the back of the waist by a mechanical device as described in detail by the accompanying drawings the subject matter of the present invention as follows.

Known dry cane 5 'by inserting a sponge in one end of the operation section 4 which is moved up and down by a crank shaft 3a connected to a rotating pulley 3 provided on the upper surface of the substrate 2 in the case 1 ) Is clamped to the head and connected to the swinging groove (5) formed so that it can be tightened by the butterfly nut (5a), the chain (7), (7 ') of the shaft (7), (7') of the swinging bridge (6). Chain gears 8 and 8 ', which are driven by 8a), are installed, but shaft 7 and oscillation section 6 are installed to be idle with each other, and one side of shaft 7 has a spring 7a. The protrusion 7b protruding from the shaft 7 is caught by the locking plate 7b ', and the other gear 9 of the shaft 7 meshes with the gear 10 protruding from the protrusion 10'. It was. At the lower side of the operation section 4, a protrusion 4a is protruded, and at the other end, a "a" shaped pressing rod 11, 12 having a neck surface 11, 12 formed at one end is protruded downward. In the lower part of the pressing section 11, the “T” shaped support section 13 formed with the protrusion 13a is piled up with the spring 13 ', and the upper section of the pressing section 12 is located below the pressing section 12. , The one-way gear 14 to be rotated by lowering operation is installed, and the bevel gears 15 and 15 ', which are capable of right-angle transmission, are engaged with the shafts 15a and 15a', and the shafts 15a '. The cranks 16, 16 "and the lever 16 'are provided between the rotary shaft 2a of the substrate 2 and the rotational movement of the shaft 15a' causes the rotary shaft 2a of the substrate 2 to be left. In other words, it is configured to flow into right.

In the drawings, reference numeral 2a 'is a fixed shaft, 17 is a chair, and M is a motor.

Referring to the effect of the present invention configured as described above are as follows.

When the bather sits on the chair 17 and drives the motor M by a separate power supply device, the operation section 4 built on the crankshaft 3a is rotated by the rotation of the pulley 3 connected thereto. , Ha works. Therefore, the swinging rod 6 connected to one end of the operating rod 4 is lowered as shown by the chain line of FIG. 1 and removes the time of the back waist.

At this time, the protrusions 10 'of the gear 10 are struck while the bar sticks 4a are raised as a synergism of the operation 4.

Accordingly, the gear 9 meshed with the gear 10 is rotated, and the chain gear 8 installed on the same shaft 7 as the gear 9 is rotated and connected to the same axis as the chain gear 8 '. 5) As shown in the dashed line of FIG. 3, the oscillating rod 6 is lowered downwards as the dashed line is shown in FIG. It was made.

When the swinging section 6 is completely lowered, since the trough 5 is lowered while being moved upward by the rotational force of the gear 10, it is separated from the back waist and the close state. At this time, the shaft 7 protrusions 7b of the gear 9 rotated by 180 ° by the rotational force of the gear 10 are caught by one end of the support section 13, and the shaft 7 by the restoring force of the spring 7a. Will block the rotation of the.

The operating section 4 that has been raised is lowered again by the crankshaft 3a. At this time, the swinging section 6 rises upwards, and the trough 5 is also raised above the back waist.

At this time, the state of the crushing groove (5) is raised from the back waist, and when fully raised, the pressing bar (11) protruding from the operation (4) is lowered, the inclined surface 11 ' The protrusion 13a of the 13 is pushed to the right, and the protrusion 7b of the shaft 7 caught by the support rod 13 is terminated as shown in FIG. 4, and is restrained by the restoring force of the spring 7a. Since the shaft 7 is reversely reversed, the gear 10 and the grinder 5 are returned to their original state. Therefore, the grinder 5 is in close contact with the back of the back and repeats the above-described process while pushing the back of the back. Can be.

Here, when the working pressure 4 is lowered, the pressing pressure 12 is also lowered while the inclined surface 12 'operates the one-way gear 14 as shown in FIG. 5 (a) to bevel gears 15 and 15'. The shaft 15a 'is rotated.

In addition, the rotational movement of the shaft 15a 'causes the substrate 2 to be moved left and right via the crank 16, 16 "and the lever 16' via the rotation shaft 2a of the substrate 2.

Therefore, the present invention when the mill 5 can be intermittently moved to the upper, lower, left, and right by a simple mechanical device transmission, there is an effect that can easily push the back waist evenly.
