Description

[Detailed description of the invention] The present invention relates to an improvement of a hook-wound band with an adjustment piece in which rectangular edge pieces and adjustment pieces are connected like a row of fish cakes when viewed from the top. The aim is to improve the workability of connecting and removing adjustment pieces.

As shown in FIG. 1, a conventional hook-wound band with an adjustment piece has flat square frames 1a and 1b formed at both ends of the back surface of an adjustment piece 1, and one of the flat square frames 1a has a groove 1a extending from the center of the inside. ' is formed.

2 is a connecting plate with two engaging pieces 2 a and 2 on both ends respectively.
It has a, 2b, and 2b.

Reference numeral 3 denotes a core frame, which has a spring portion 3a in the center that can be curved in the vertical direction, and has a protrusion 3b' on the base portion 3b.

When connecting the adjusting pieces 1, insert the engaging pieces 2b, 2b at the ends of the connecting plate 2 into the flat rectangular frame 1b of one side of the adjusting pieces 1 placed adjacent to each other.
and then insert one retaining piece 2 on the other end of the connecting plate 2.
a to the groove 1a in the other flat rectangular frame 1a of one adjustment piece 1.
′ and pull it horizontally, then remove the flat rectangular frame 1 on the side of the groove 1a′.
a Insert and lock on the bottom surface.

Next, while tilting the other adjusting piece 1 slightly, the other retaining piece 2a of the connecting piece 2 is inserted into the groove 1a' in the flat rectangular frame 1a of the adjusting piece 1.
by placing the adjustment piece 1 horizontally, the engagement piece 2
a is located on the lower surface of the flat square frame 1a on the side of the groove 1a'.

Next, insert the core frame 3 between the connecting plate 2 and the already connected connecting plate 2, and insert the core frame 3 into one of the flat rectangular frames 1b.
the other flat 4 while pressing the base 3b downward.
It is inserted into the lower surface of the square frame 1a, and the protrusion 3b' is fitted and locked into the groove 1a'.

In this way, the adjustment pieces are successively connected.

When removing it, just do it in the opposite direction. However, the connecting piece 2 of the connecting plate 2
The work of inserting the grooves 1a and 2a into the grooves 1a' and 1a' and locking them to the lower surface of the flat rectangular frame 1a is extremely troublesome and requires skill, resulting in poor workability.

The present invention is designed to eliminate these drawbacks.
Next, one embodiment shown in FIGS. 2 to 6 of the accompanying drawings will be described in detail.

10 is an adjustment piece with flat square frames 10 a on both ends of its back side;
10b, a hole 10a' is formed in the center of one flat rectangular frame 10a, and an i-shaped engagement piece 10C is formed in the center of both sides of the back side.
, 10C all in one piece.

Reference numeral 11 denotes a four-cornered connecting ring large enough to fit and lock onto the r-shaped engagement piece 10C; 12 has a spring portion 12b in the center that can be bent in the vertical direction; and a protrusion 12b at the base. It is an adjustment pin with

Next, when connecting the adjustment pieces 10, each adjustment piece 10 in which the i-shaped engagement pieces 10C on both sides of each adjustment piece 10 are arranged adjacently to each other.
The connecting tongues 11 are respectively fitted to the adjacent i-type engaging pieces 10C to connect them.

A predetermined interval is formed between each connecting ring 11, so the adjustment pin 12 is inserted into this interval and the tip is flattened 4.
The protrusion 12b is inserted into the square frame 10b, the base is pushed down against the elasticity of the spring part 12a, and the protrusion 12b is inserted into the flat square frame 12.
When the push-down force is released by aligning it with the hole 12a' of a, the adjustment pin 12 is pushed upward by the elasticity of the spring portion 12a, the protrusion 12b is fitted into the hole 12a', and is held in that position, and the connection is completed. The ring 11 is also held and connected without play.

To remove it, simply push down the adjustment pin 12, pull it out to remove it from the adjustment piece 10, and then remove the connecting ring 11 from the i-shaped engagement piece 10C.

According to the present invention, the connecting ring is connected to both the adjacent adjusting pieces.
The work of fitting and connecting to the mold retaining piece is extremely simple and can be easily done without requiring any skill, so the workability of connecting and removing the adjusting piece is good.
