Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting device for a rubber knitting machine for a hand knitting machine.

[Conventional technology]

Conventionally, as this type of device, for example,
- As shown in Publication No. 11153, the hanging part of the support plate bent into an approximately L-shaped cross section is attached to the rubber machine needle bed, and the upper horizontal part is attached to the front edge of the machine needle bed. Some types of fitting means are installed between the upper horizontal part of the needle bed and the needle bed of the machine, and have a substantially uneven fitting means that can be fitted into and removed from the needle bed.

[Problem that the invention attempts to solve]

However, according to the conventional method, when the rubber machine needle bed is supported on the machine needle bed, the upper horizontal part of the support plate is inserted into the front insertion hole and the rear insertion hole of the machine needle bed. However, especially when inserting the upper horizontal part of this support plate from the front insertion hole to the rear insertion hole, the rear insertion hole is almost covered by the butt guide groove plate above it. Since you cannot see it, you have to insert it by feeling, and if the rear end of the upper horizontal part shifts even slightly in the vertical direction with respect to the rear insertion hole, it will not be able to be inserted into the rear insertion hole. In this case, the needle bed of the rubber machine, which is quite heavy, must be supported by hand, which is very troublesome and time-consuming.

[Purpose of invention]

Therefore, the present invention makes it possible to carry out the work of supporting the rubber machine needle bed with respect to the machine needle bed extremely easily and quickly, and furthermore, once it is supported, the rubber machine needle bed is ensured in the specified position. It is intended to be placed in

[Means for solving problems]

A rod-shaped support that is arranged horizontally on the left and right above a gap that is slightly larger than the thickness of the plate, and that rotatably supports the inner part of the L-shaped bent part of the support plate that is inserted into the gap from the front. A rod is provided, and a receiving piece is provided on the upper rear side of the mounting member to receive an upper surface of the rear end of the upper horizontal portion supported by the support rod and in which the fitting means is engaged. It is characterized by:

[Effect]

According to the above-mentioned means, when the rubber machine needle bed is supported on the main machine needle bed, the upper horizontal part of the support plate is inserted through the gap of the mounting member, and the inner part of the L-shaped bent part is moved backward until it abuts against the support rod, and in this state, the rubber machine needle bed is released from the hand, whereby the fitting means performs the fitting action and the upper surface of the rear end part of the upper horizontal part is received by the receiving piece, whereby the rubber machine needle bed is arranged in a predetermined position. Conversely, to remove the rubber machine needle bed from the main machine needle bed, the rubber machine needle bed is lifted and rotated slightly around the support rod to release the action of the fitting means, and then the rubber machine needle bed is moved forward, and the upper horizontal part of the support plate is released forward from the gap of the mounting member.
