Abstract

PURPOSE: To obtain the subject needle haunting a slider and a needle main body in one body on a needle groove by engaging a slider base part in a depressed notched part in a side face of a needle bat and piercing a tongue base part into a guide hole in a needle main body. CONSTITUTION: This compound needle has a slider 3 engaged in a depressed groove 8 located at an upper edge part of a needle main body 2 in freely sliding. A base part 18 of the slider is engaged with a depressed notched part cut on a side face of a needle bat 7 and a base part of a tongue 13 of the slider is pierced into a guiding hole 10 of the needle main body, then either of the needle bat 7 or a slider bat 23 is pushed down, thus the slider and the needle main body haunt in the needle groove in one body.

Description

[Detailed description of the invention]

[Industrial Field of Application 1] The present invention relates to compound needles used in knitting machines. [Prior Art] A compound needle is known in which a slider is slidably attached to a needle body, and as the slider slides, a tongue at the tip of the slider advances and retreats from a hook at the tip of the needle body, opening and closing the hook. 1978-
No. 109664). In a known compound needle, a slider is slidably fitted into a groove provided in the needle body, and the slider is slid by bringing the slider butt into contact with a cam. The slider is prevented from falling off by pressing the slider from above with a band that is provided across the needle body in the longitudinal direction of the needle bed. The slider butt acts only on the forward and backward movement of the slider, and cannot cause the needle body to move forward and backward or move in and out through the slider butt. [Problems to be solved by the K invention] In a compound needle that combines a needle body and a slider, the slider and needle body are each operated and slid by separate cams,
It can be said that the two are in a relationship that allows them to work together in forward and backward movements. However, if the slider is simply fitted into a groove provided on the upper edge of the needle body, the slider butt may not be pushed in even if the needle butt is pushed into the needle bed. There will be. In view of the above points, an object of the present invention is to obtain a compound needle that can simultaneously and integrally move in and out of a needle groove by integrating a slider and a needle body.

[Means to solve the problem]

A slider having a slider butt at the upper edge and a tank at the tip is slidably fitted into a groove provided in the upper edge of the needle body, and the tongue is inserted into the groove following the groove. The slider base was inserted into a guide hole provided in the needle body and grasped by its base, and the slider base was slidably fitted into a recess cut out on the side surface of a needle butt provided at the upper edge of the needle body. 1 Action] Since the slider base is fitted into the recess cut out on the side of the needle butt, and the tank base of the slider is inserted into the guide hole of the needle body, the needle rose l-1 is attached to the slider. By pressing down on either of the butts, the slider and the needle body move in and out of the needle groove as a unit. K Embodiment An embodiment of the compound needle 1 of the present invention will be described next. The compound needle 1 of the present invention consists of a needle body 2 and a slider 3. The needle body 2 is made by punching out a plate-shaped body, and has a hook 4 at the tip, a bent part 5 at the base end that comes into contact with the needle bed surface, and the upper edge of the central shank 6. A needle butt 7 is provided, and a concave groove 8 in which the slider 3 is slidably fitted is provided in the tip end of the upper edge. Guide holes 10 that fit into the shank 6 are provided in the throws 1 to 9 of the concave groove 8 at positions closer to the hook. The guide hole 10 is formed by bending the upper ends of both side walls 11 and 12 of the groove 8 inward to close the upper part of the groove 8. hook 4
The tip of is the tongue 1 provided at the tip of the slider 3, which will be described later.
A recessed portion 14 is formed such that the number 3 can be inserted thereinto. A guide 15 is formed below the throat portion 9 of the shank 6, with which the hook of the needle on the receiving side comes into contact during transfer. The side surface of the shank 6 forming the guide 15 is connected to a transfer plate spring 1 provided on the slider 3, which will be described later.
A thinly cut portion 17 is provided so that the tip of the portion 6 comes into contact with the portion 17. Needle rose! - A recessed notch 19 into which the base 18 of the slider 3 fits is provided on the side surface of the slider 7. The slider 3 is made by punching out a plate like the needle body 2, and its thickness is the same as that of the needle body, and a protrusion 20 is provided at the lower edge of the shank 21.
A tongue 13 is provided at the tip. The protrusion 20 is thinner than the shank 21 and is slidably fitted into the groove 8 of the needle body 2, and the tongue 13 is
When inserted through the guide hole 10 of the needle main body 2 and advanced the most, it engages with the concave portion 14 of the hook 4 and closes the hook 4. On the side of the shank 21 is a leaf spring 1 for transfer.
6 is provided. The base of the slider 3 has a concave notch 2
2 is provided, and when the slider 3 is combined with the needle body 2, the concave notch 19 of the needle body 2 and the concave notch 22 of the slider 3 fit together, so that the slider 3 can slide with respect to the needle body 2. It is. When using the compound needle 1 of the present invention, in order to slide the slider 3 and open and close the hook 4 with the tongue 13 at its tip, the slider butt 23 is raised and lowered by a slider lifting cam (not shown), and in order to raise and lower the needle body, The slider is lowered by contacting the needle butt 7 with a needle elevating cam or by the slider elevating cam, and by pushing the needle body with the slider. In order to raise the needle body with the hook 4 open, a cam is brought into contact with the needle butt 7 and the needle body 2 is raised, and the already knitted green loop is locked to the stepped portion 24 of the slider 3. Therefore, the slider 3 is prevented from rising and only the needle body 2 rises. However, if the front edge 25 of the needle rose l-7 comes into contact with the front edge 26 of the recessed part 22 of the slider 3, the needle body 2 will rise and the needle body 2 will rise. Slider 3 will also rise. When pushing the compound needle 1 into the needle groove, the purpose is achieved by pushing the needle butt 7 or slider butt 23 because the needle body 2 and slider 3 are integrated by the M4 structure as described above.

【Effect of the invention】

A slider having a slider butt at the upper edge and a tongue at the tip is fitted into a concave groove provided on the upper edge of the needle main body such that the slider can move freely in the R direction, and the tongue is inserted into the needle following the concave groove. The slider base is inserted into a guide hole provided in the needle body and gripped by its base, and the slider base is slidably fitted into a recess cut into the side of the needle butt provided at the upper edge of the needle body. Therefore, by pressing down either the needle butt or the slider butt, the slider and the needle main body can be operated as one and moved into and out of the needle groove.
