At the base end, cut out the lower part from the circumferential groove (11)
3) is provided.

A core wire (21) inserted through the opening edge of the bag-like net (2) is fitted into the circumferential groove (11) of the frame (1) so that both ends of the core wire are inward from the notch (13) of the frame (1). The screw shaft (61) is pulled in, bundled, inserted into the hollow screw shaft (61), caulked at its tip and integrated, and the screw shaft (61) is positioned between the bent portions (12) (12).

The bent portions (12) (12) at both ends of the frame (1) and the screw shaft (61) are accommodated in a frame fixing device (3). The frame fixture
As shown in FIG. 3, (3) is constructed by bolting a frame fixing tool main body (4) and a fixing tool holding plate (5).

The frame fixing device main body (4) has a front surface corresponding to the frame (1).
It is formed in a flat body in which the distance between both sides gradually decreases from (40) to the rear. On the upper surface of the frame fixture main body (4), grooves (42), (43) and (43) are formed at the center and both sides, and the central groove (42) opens at the front and rear end surfaces of the frame fixture main body (4), Grooves on both sides (43) (43)
Is opened at the front end of the frame fixture main body (4) and the other end is closed.
The front portion between the grooves (42) and (43) is shaved to form low step portions (47) and (47).

The fixture holding plate (5) is provided with the fixture main body (4).
A pressing piece (52) that sandwiches the core wire (21) between the fixing tool main body (4) and a cover piece (5) that covers the upper surface of the fixing tool main body (4).
A groove (53) in which the core wire (21) fits is formed on the inner surface of the holding piece (52).

The cover piece (51) and the frame fixing device main body (4) have counterbore bolts penetrating vertically at positions corresponding to the low step portions (47) and (47) of the frame fixing device main body (4). Hole (48) is opened and bolt (4
5) The head and nut (46) sink into the counterbore of the bolt insertion hole.

A tightening mechanism (6) for fitting the core wire (21) into the circumferential groove (11) of the frame (1) to tighten it is provided on the frame fixing tool (3). The fastening mechanism (6) shown in FIGS. 2 and 3 is an example of the U-shaped washer (62) in which a screw shaft (61) protruding from the end face penetrates the tip end face of the frame fixing tool (3). Is fitted with the screw shaft
Double nuts (63) and (63) are screwed into the protruding part of (61), and the frame fixing device (3), screw shaft (61), U-shaped washer (62) and double nuts (63) (63) The core wire (21) to pull the groove of the frame (1)
(11) is strongly engaged.

The handle (7) has at its tip a flat insertion hole (71) in which the frame fixing device (3) is fitted tightly, and both side walls (72) of the hole (71) are connected to the frame fixing device (7). It inclines corresponding to both slopes (41) of 3). 4 and 5, handle (7) and frame fixing device
(3) is provided with a pulling mechanism (8) for pulling the frame fixing device (3) deep into the insertion hole (71).

The pulling mechanism (8) is composed of a circular cam plate (81) attached to the handle (7) and a projection (88) formed on the lower surface of the frame fixture (3). As shown in FIG. 7, the cam plate (81) has a retaining flange (85) at the upper end of a short shaft (84) which is rotatably fitted into a hole (74) formed through the lower surface of the handle (7).
And a recess (82) is formed on the upper surface of the flange (85). The dent (82) is partially open to the side (82a),
The inner peripheral surface of (82) is gradually depressed clockwise from the opening (82a).
An eccentric cam surface (83) approaching the center of (82).

A drive groove (86) into which a part of a coin fits is formed on the lower surface of the cam plate (81). On the lower surface of the fixture body (4), a cam plate (8
A fitting chamber (87) for accommodating the flange (85) of 1) is opened, and a projection (88) is provided at the center of the fitting chamber (87).

The procedure for attaching the net (2) to the frame (1) and attaching the handle (7) will be described below. The core wire (21) inserted through the opening edge of the bag-like net (2) is fitted into the circumferential groove (11) of the frame (1), and both ends of the core wire (21) are inward from the notch (13) of the frame (1). And the screw shaft (61) is positioned between the bent portions (12) and (12).

The core wire (2) is inserted into the central groove (42) of the fixture main body (4).
1) The upper screw shaft (61) is fitted, the tip of the screw shaft (61) is made to protrude from the rear end of the fixture main body (4), and the grooves (43) ( Fit both bent portions (12) and (12) of the frame (1) into 43).

The holding piece (52) of the fixture holding plate (5) is connected to the core wire (21).
The cover piece (51) is placed on the upper surface of the fixture main body (4), and the fixture main body (4) and the fixture holding plate (5) are fixed with bolts (45) and nuts (46). . At this time, a sleeve (44) is interposed between the fixture main body (4) and the fixture holding plate (5), and the sleeve is fitted to the bolt (45).

A U-shaped washer (62) is applied to the rear part of the frame fixing tool (3) to make the tip of the screw shaft (61) project from the washer (62), and the double nut (63) (63) ), Pull out the screw shaft (61), and pull the core wire (21). As a result, the core wire (21) fits tightly into the circumferential groove (11) while pressing the frame (1) inward.

The core wire (21) drawn into the frame fixture (3) comes into contact with the sleeve (44) fitted on the bolt (45), so that the bolt (45) and the core wire (21) directly rub against each other. The bolt or the core wire (21) can be prevented from being damaged.

Insert the frame fixing tool (3) into the insertion hole (71) of the handle (7).
Fit into The flange (85) of the cam plate (81) fits into the fitting chamber (87) of the frame fixing device (3), and the projection (88) of the frame fixing device (3).
Is recessed from the side opening (82a) of the recess (82) of the cam plate (81) (82).
(FIGS. 8A and 8B). Rotation groove (86) of cam plate (81)
And turn the drive groove (86) counterclockwise. The projection (88) of the frame fixing device (3) slides on the eccentric cam surface (83) of the cam plate (81) and is pulled deep into the insertion hole (71). As a result, the entire frame fixing device (3) is drawn toward the inner side of the insertion hole (71), and the slopes (4) of the frame fixing device (3) are placed on both side slopes (72) of the insertion hole (71).
1) is pressed, and the frame fixture (3) fits tightly into the insertion hole (71) (FIGS. 9A and 9B).

As described above, the frame fixing member (3) is formed in a flat body, fits in the flat insertion hole (71) of the handle (7), and is pulled into the insertion hole (71) by the pulling mechanism (8). Side (7) because it is drawn to the side and is tightly fitted in the insertion hole (71).
The frame and the frame (1) do not rotate relative to each other, so that it is possible to reliably prevent the frame from rotating and failing to receive fish, or the frame from coming off.

FIGS. 11 and 12 show another embodiment of the pulling mechanism (8) for pulling the frame fixture (3) deep into the insertion hole (71) of the handle (7). The pulling mechanism (8) includes a worm screw (89) that penetrates the wall surface of the handle (7) and is rotatably disposed with its axis oriented in the insertion direction of the frame fixing device (3), and a frame fixing device (3). ) And a rack surface (80) that can be engaged with the worm screw (89) .The screw thrust generated by engaging the worm screw (89) and the rack surface (80) and turning the worm screw (89) is used. The frame fixing tool (3) is pulled into the inside of the insertion hole (71), and the frame fixing tool (3) is tightly fitted and fixed in the insertion hole (71).

The description of the above embodiment is for the purpose of illustrating the present invention, and should not be construed as limiting the invention described in the claims for utility model registration or reducing the scope. Further, the configuration of each part of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made within the technical scope described in the claims for utility model registration.
