A locking projection 3a that can be engaged is projected, and is always biased and held in one of the moving positions shown in FIG. 1 by a compression spring 4 interposed between one side thereof and the mounting plate 1. In order to switch the various types of switching cams (not shown) provided on the underside of the carriage to a state suitable for two-color simultaneous knitting, slip stitch knitting, tuck knitting, etc., the operating rod 2 selects the push button 2b. When pressed backward from the front position by operation, the locking recess 2a and the locking protrusion 3a are reciprocated left and right by a predetermined amount.
The operating rod 2 is held in the rearward movement position by engagement with the rearward moving position.

Reference numeral 5 denotes a sliding plate as a driving member which is supported on the rear end of the upper surface of the carriage base plate behind the mounting plate 1 so as to be movable left and right, and the sliding plate 5 is attached to the rear surface of the mounting plate 1 on the front edge thereof. A plurality of engaging recesses 5a are formed to engage with the elastic retaining plate 6, and the carriage can be flattened through a pinion and a rack plate (not shown) by means of an appropriate rotation operation knob provided on the upper surface of the carriage base plate. Four positions for stitching, pattern stitching, one-point pattern stitching (partial pattern stitching), and carriage removal I, II, II
A guide cam, etc., which are arranged to be switched between I and IV and which guide the butt of the knitting needle to the needle selection cam mechanism provided on the lower surface of the carriage, is switched to a position suitable for the pattern knitting, etc.

Next, the sliding plate 5 is placed at position II or III, and the operating rod 2 that has been selectively operated is held at the rear position, so that pattern knitting such as two-color simultaneous knitting or one-point pattern knitting is performed. When switching to the flat knitting state by moving the sliding plate 5 to position I using the rotating operation knob etc., the operation rod 2 is moved to the holding rod 3 based on the movement of the sliding plate 5. The mechanism for releasing the rear pressing and holding position will be explained below.

Reference numeral 7 denotes a rotating lever that is rotatably supported on the upper surface of one side of the mounting plate 1 by a support pin 8 at the intermediate portion and displaceable in the axial direction, and its monopod 7a is connected to the elastic retaining plate. The other leg 7b is extended to the vicinity of one side end of the holding rod 3 and engages with the end of the holding rod 3. It corresponds to possible.

Reference numeral 9 denotes a coiled spring that is wound around the support pin 8 on the upper surface of the rotary lever 7, and its both ends are hooked to the monopod 7a of the rotary lever 7 and the mounting plate 1, respectively. 7 is urged to rotate clockwise in FIG. The lever 7 is pressed downward along the axis and is normally held in contact with the upper surface of the mounting plate 1.

Reference numeral 11 denotes a substantially chevron-shaped drive piece formed on the upper rear end of the sliding plate 5 so as to be able to engage with the rear edge of the monopod 7a of the rotating lever 7. 5 is position II, II
When the sliding plate 5 is placed in positions I and IV, it does not engage with the monopod 7a of the rotating lever 7, and when the sliding plate 5 is switched to the position ■, as shown in FIGS. 4a and 5a, At the beginning of its movement, it engages with the monopod 7a of the rotating lever 7, and the rotating lever 7 is rotated counterclockwise against the action of the coil spring 9.

Accordingly, with the rotation of the rotation lever 7, the holding rod 3 is moved to the left from the state shown in FIG. 1 by the other leg 7b against the action of the compression spring 4, as shown in FIG. 4a. The operating rod 2 with its latching protrusion 3a in the rear pressing and holding position.
The operating rod 2 and push button 2 are removed from the latching recess 2a.
After b is released from the pressed state, it is returned to the forward position by the action of a compression spring (not shown) applied thereto.

As a result, all the switching cams and the like on the lower surface of the carriage, which are arranged in a state suitable for pattern knitting, etc., are automatically switched to a state suitable for plain knitting.

Reference numeral 12 denotes a retainer protruding from the upper part of the base end of the elastic retaining plate 6 so as to be located within the rotation locus of the monopod 7a of the rotation lever 7 and to be able to engage with the monopod 7a. As shown in FIG. 3, the operating protrusion as a release member has an inclined surface 12a on its side edge corresponding to the one leg of the rotating lever 7, and the rotating lever 7 is connected to the holding rod 3. Immediately after the actuating protrusion 12 is rotated by the amount necessary to release and move it by a predetermined amount, the operating protrusion 12 engages with the monopod 7a of the rotary lever 7, and as shown in FIGS. 2 and 5b, The monopod 7a is attached to the coiled spring 9 along the inclined surface 12a.
The monopod 7a is displaced upward against the action of the monopod 7a, and the engagement between the monopod 7a and the drive protrusion 11 is released.

Therefore, after the engagement between these two 7a and 11 is released,
As shown in FIGS. 4b and 5b, the rotating lever 7 is rotated back to its original position by the action of the coil spring 9 with its monopod 7a riding on the upper end of the driving protrusion 11, and then slid. Only the plate 5 is further moved toward the position (2), and the guiding cams and the like on the lower surface of the carriage are switched to a state suitable for ten stitches.

The operation of the operating mechanism constructed as described above will now be described.

Now, FIGS. 1 to 3 show the pattern knitting switching state in which the sliding plate 5 is placed at the pattern knitting position II and the arbitrary operating rod 2 is held at the rear pressing operation position.

In this state, turn the rotation control knob on the top of the carriage (
When the sliding plate 5 is moved to the position (2) and switched to the plain knitting state using a button (not shown) etc., as the sliding plate 5 slides, the rear edge The driving protrusion 11 engages with the monopod 7a of the rotating lever 7, and the rotating lever 7 is rotated counterclockwise against the action of the coil spring 9.

With this rotation and the rotation of the lever 7, the holding rod 3 is moved to the left from the state shown in FIG. The locking recess 2a is released from the locking protrusion 3a of the holding rod 3, and the operating rod 2 and push button 2b are returned to the forward position by the action of the compression spring applied thereto.

Therefore, various switching cams and the like on the lower surface of the carriage are automatically switched from positions suitable for pattern knitting to positions suitable for flat knitting.

Immediately after the rotating lever 7 is rotated by the amount necessary to release and move the holding rod 3 by a predetermined amount as described above, the monopod 7a engages with the operating protrusion 12, and as shown in FIG. As shown in FIG. 5b, the one leg 7a of the rotating lever 7 is displaced upward against the action of the coil spring 9 by the inclined surface 12a, and is released from the engagement with the driving protrusion 11. Ru.

After the engagement between these two 7a and 11 is released,
As shown in FIGS. 4b and 5b, the rotating lever 7 is rotated back to its original position by the action of the coil spring 9 with its monopod 7a riding on the upper end of the driving protrusion 11, and then slid. Only the plate 5 is further moved toward position (2), and the guiding cams and the like on the lower surface of the carriage are switched to a position suitable for flat knitting.

Therefore, even when the amount of movement of the sliding plate 5 is large as described above, the rotating lever 7 is always rotated by a predetermined amount at the beginning of the movement and then returned to its original position, regardless of the amount of movement, so that no force is applied to each member. The holding rod 3 is reliably released and moved by a predetermined amount by the rotating lever 7 without any force being applied.

Next, another embodiment of this invention will be described with reference to FIG. 6. In this embodiment, the rotating lever 7 is formed of a thin elastic plate, and the monopod 7a is supported against its own elasticity. It is designed to be displaced upward.

Therefore, as in the previous embodiment, as the sliding plate 5 moves, the rotating lever 7 is rotated by the driving protrusion 11, and immediately after the holding rod 3 is released and moved by a predetermined amount at the other end 7a, the monopod is moved. When the monopod 7a engages with the working protrusion 12, the monopod 7a
a is displaced upward against its own elasticity and released from engagement with the driving protrusion 11.

Further, in this embodiment, it is sufficient to provide a spring 13 that biases the rotary lever 7 only toward the original position in the rotation direction.

Note that this invention is not limited to the structure of each of the embodiments described above, and the structure of the rotary lever, drive member, actuated body, disengagement member, etc. may be arbitrarily changed, or a hand knitting machine may be used. It is also possible to implement it in other mechanisms.

As described in detail above, this invention operates by moving a driving member to engage the edge of one leg of a rotating lever whose intermediate portion is rotatably supported on one shaft. In an actuating device for an actuated body in which the actuated body is actuated by the other leg by rotation, at least one leg of the rotary lever is engaged with or disengaged from the drive member. The lever is displaceable in the axial direction of the shaft within a range of positions, and the rotating lever is always biased by a spring means toward one displacement position in the axial direction where it can be engaged with the drive member. , the rotation lever is biased in a rotation direction opposite to the rotation direction of the monopod, and the monopod is pushed by the drive member at a position corresponding to the rotation locus of the monopod. Immediately after the actuating body is rotated by the amount necessary to actuate the predetermined amount, the monopod is engaged with the monopod to displace the monopod to the other displacement position in the axial direction against the action of the spring means. By providing an engagement release member that releases the engagement with the drive member, even if the drive member is moved a large amount, the rotation can be made within a certain predetermined range of movement, regardless of the amount of movement of the drive member. After the lever is always rotated by a predetermined amount, it is returned to the original position of the rotation, and the actuated body is reliably operated by the predetermined amount by the rotation of the rotary lever without applying unreasonable force to each member. It is also advantageous in that it is not necessary to set the amount of movement of the drive member according to the amount of rotation of the rotation lever required to operate the actuated body by a predetermined amount, making it easy to design and manufacture. It has a great effect.
