Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand knitting machine whose needle bed can be folded and housed in a case.

Conventionally, this type of hand knitting machine was manufactured using the Utility Model 36-26160.
The one disclosed in the publication No. 1 is known. The main body of this hand knitting machine is constructed by fixing a cover plate to the needle bed, which covers the needle bed from the bottom to the rear of the top.
This main body is divided into two parts at the center and the two sides are connected with a hinge so that the main body can be folded in half. I'm trying to make it easier. On the other hand, the case consists of three lid plates that are hinged to each other: a side lid plate that covers the front edge of the main body, a bottom lid plate that covers one end of the main body, and a bottom lid plate that covers the other end of the main body. The structure is such that the main body is covered with a case along with its covering plate. Further, a handle is provided on one bottom cover plate of the case, so that when carrying the case, the folded main body and the carriage on the needle bed are carried vertically together with the case.

However, this has the following drawbacks.

Since a cover plate for covering the carriage must be separately attached to the needle bed, the overall size of the main body becomes large.

Because the case is divided into three lid plates,
It takes a lot of effort to cover the main body.

When carrying, the folded main body and the carriage on the needle bed are carried vertically, so that unnatural force is generated between the carriage and the needle bed, damaging them.

Since the case must be inverted when being carried, it is difficult to provide a storage section inside the case to store accessories.

The present invention proposes a hand knitting machine that does not have such drawbacks, and its feature is that the needle bed is divided into three parts, a central part and left and right side parts on both sides, which can be bent and rotated freely. On the other hand, the case is divided into two halves, a front half and a rear half, and the size of the accommodation space formed when these halves meet is determined by making the left and right sides of the needle bed stand up with respect to the center. The center part is made large enough to accommodate the entire needle bed when placed on the bottom plate of both the front and rear halves, and a handle is provided on the upper part of both the front and rear halves, and the inner surface of at least one half is made large enough to accommodate the entire needle bed. To,
When the needle bed is accommodated, a parts accommodating part is provided so as to protrude between the left and right sides of the needle bed and located above the carriage placed in the center thereof.

The needle bed 1 is set to operate in conjunction with the sliding movement of a carriage 26 that is slidably mounted on the needle bed 1. The structure and operation of the stage number counter 23 are the same as those of the known ones, so a description thereof will be omitted.

The carriage 26 is provided with a knitting cam mechanism (not shown) corresponding to plain knitting, pattern knitting, etc. on the lower surface, and is equipped with needle selection devices 27, 27 on both the left and right sides, as well as a thread opening for the base yarn and a colored yarn. A knitting presser foot 28 equipped with a yarn opening (not shown) is mounted on the front side by a hinge 29 so that it can be moved between a used position (solid line in Figure 3) and an unused position (dashed line in the same figure). There is. 3
0 is a starting member protruding from the rear side of the carriage 26,
This is to operate the needle selection signal applying device 24.

The needle selection device 27 is a well-known device, and the required unit pattern (24
A memory piece 31 that stores needle selection signals constituting needle selection)
A memory rotary body 32 which is swingably mounted in a radial manner, and a needle selection piece (not shown) that receives a needle selection signal from the memory piece 31 and selects the knitting needle 7 in two positions, front and back. The needle selection rotary body (not shown) is provided with the same number of memory pieces 31 and mounted in the same state. Then, a gear (not shown) fixed to the storage rotor 32 meshes with the rack 4 of the needle bed 1 and rotates in conjunction with the sliding movement of the carriage 26, whereby the storage rotor 32 and the needle selection rotor are rotated. The rack 4 is rotated, and the needle selection piece engages with the butt 7b and selects the needle in two positions, front and rear, depending on whether or not it is moved forward.

The needle selection signal giving device 24 attaches a signal card 33 on the upper side of the frame 25, in which a needle selection signal constituting a required unit pattern (24 needle selections) is displayed in multiple stages by a perforated part 33a and a non-perforated part 33b. a roller 34 that moves outward in a predetermined direction; and the activation member 30.
a drive mechanism 35 that rotates the roller 34 by engaging with the passive piece 35'; and a storage rotating body 3.
The signal reading piece 36 reads the needle selection signal of the signal card 33 in relation to the rotation of the signal card 2 and transmits the signal to the memory piece 31. The signal reading pieces 36 are made of synthetic resin and have the same number as the memory pieces 31, and each base end is rotatably supported on a support shaft 37 horizontally suspended in the frame 25 in the direction of movement of the memory rotating body 32. They are lined up in

The signal reading piece 36 has an engaging piece 36a that engages with the memory piece 31 on the front side of the tip, and a pin-shaped reading part 36b that projects into the signal hole 33a on the rear side of the tip.
Also, a spring part 36c is integrally formed on the rear side of the base end, and the engaging part 36a and reading part 36b thereof are made to protrude upwardly and outwardly from the frame 25, and the spring part 36c is attached to the spring stopper bar 38. It makes elastic contact and applies a rotational force in the counterclockwise direction as shown in Fig. 8. Therefore, each signal reading piece 36 is always waiting at a front position (solid line in FIG. 8) in which the reading part 36b faces the front of the perforated part 33a and the non-perforated part 33b on the upper outer side of the frame 25. As the storage rotary body 32 rotates, the corresponding storage piece 31 engages with the engaging portion 36a at a substantially horizontal outer position (dashed line in the figure) and is pushed rearward. In this case, the signal reading piece 36 has a perforated portion 33.
When a is facing the signal reading piece 36, the signal reading piece 36 is displaced to the rear position (dashed line in the figure) where the reading part 36b enters the perforated part 33a, and as a result, this signal reading piece 3
The memory piece 31 corresponding to number 6 continues to maintain its outer position. Further, when the non-porous part 33b is facing the reading part 36b, the reading part 36b comes into contact with the non-porous part 33b, and the backward movement is prevented and the signal reading piece 36 maintains the front position, and as a result, the memory piece 31 is reversed. It is pushed and displaced to a downwardly inclined inner position (solid line in Figure 8). Thus,
The needle selection signal read by the signal reading piece 36 and stored when the memory piece 31 takes either the inner or outer position is transferred to the corresponding needle selection piece of the needle selection rotary body, and the needle selection signal is transferred to the corresponding needle selection piece of the needle selection rotary body. Therefore, the desired unit pattern is selected. Moreover, since the needle selection signal to be read by the signal reading piece 36, that is, the perforated portion 33a and the non-perforated portion 33b, are exposed on the upper side of the frame 25, the knitting person can directly see them and receive the needle selection signal. and the patterns that are knitted can be identified.

Moreover, since the entire needle bed can be accommodated in the case with the central portion placed on the bottom plates of both the front and rear halves of the case, the needle bed can be shortened to, for example, one-third of its total length. It can be stored inside the case.

When storing the needle bed in a case and carrying it around, the carriage is placed in the center of the needle bed and can be carried with the center and carriage held horizontally, so the needle bed and carriage can be placed vertically. Unlike when the needle bed and the carriage are carried together with a case, there is no unnatural gravity exerted on the needle bed and the carriage, which could damage them.

Since a parts storage part is provided protruding from the inside surface of at least one of the front and rear halves of the case, accessories, knitting yarn, signal cards, etc. can be stored, carried, and stored therein.

When the needle bed is housed in the case, the above-mentioned parts storage section is located between the upright left and right sides of the needle bed and above the carriage placed in the center, so there is no room in the case. The above-mentioned accessories can be stored by making effective use of the space, and the left and right sides of the needle bed can also be prevented from falling down by the parts storage section.
