Hereinafter, embodiments of the present invention will be described with reference to the drawings. The fasteners of the embodiment of the present invention shown in FIG. 1 include a fastening belt 3 for fastening luggage and the like, a reel for winding a fastening belt (not shown), and a belt tightening member 2 as a driving means for rotating the reel to tighten the fastening belt. A belt lock member 1 for locking the movement of the fastening belt is provided. A front fastening member 5 is provided at one end of the fastening belt, and the other end of the fastening belt is fixed to the reel of the fastener. Further, a rear fastening member is provided at the rear portion of the fastener 10. The front fastening member and the rear fastening member are formed in a substantially L shape so that they can be easily attached to the end of the plate of the flat trolley.

The tightening operation of the belt 3 will be described with reference to FIGS. 1 and 2. First, the fastener shown in FIG. 1A shows that the belt tightening member 2 is in the standby state and the belt lock member 1 is lifted. Since the belt lock member 1 is lifted, the fastening belt 3 is released from the locked state and the fastening belt 3 can move freely. In this state, the fastener 10 is attached to a trolley or the like with the rear fastening member 6. Then, after the fastening belt 3 is hung on the luggage, the front fastening member 5 provided at one end of the fastening belt 3 is attached to a trolley or the like. Since the fastening belt 3 is urged in the winding direction by the spiral spring 171 built in the reel, the excess belt pulled out is automatically wound on the reel, but the tightening force is not sufficient to prevent the load from collapsing. Since it is sufficient, it is necessary to tighten it with the belt tightening member 2 that drives the fastening belt in the tightening direction.

FIG. 1B shows a state in which the belt tightening member 2 is rotated toward the feeding side of the belt. Since the belt lock member 1 is in a position where the movement of the fastening belt 3 is released, the belt can move freely. The belt tightening member 2 in the standby state of FIG. 1 (A) is rotated in the feeding direction of the belt to bring it into the state of FIG. 1 (B). Then, the reel attached to the belt tightening member 2 rotates and winds up the fastening belt 3, so that the feeding length of the fastening belt 3 is shortened and the luggage is tightened. Since the drive lever of the belt tightening member 2 is sufficiently distanced from the rotating shaft, a high tightening force can be obtained by the principle of leverage.

When the belt lock member 1 is tilted toward the belt in order to prevent the fastening belt 3 from moving so that the fastening belt that tightens the load in FIG. 1 (B) does not loosen, the state shown in FIG. 2 (A) is obtained. Then, when the lever of the belt tightening member 2 is moved to the standby state, the state shown in FIG. 2B is obtained.

A belt lock for preventing the movement of the belt will be described with reference to the cross-sectional view of the fastener shown in FIG. In this embodiment, a commercially available cam buckle is used as a mechanism for preventing the movement of the belt. The cam buckle acts to prevent the belt from moving by locking the belt passed through the cam buckle by a built-in spring.

As shown in FIG. 3A, when the release lever drive member connected to the lever of the belt lock member pushes the release lever 21 of the cam buckle shown in FIG. 4, the belt is released from locking and the belt can move freely. Will be. The spiral spring built into the reel is a urging means for rewinding the belt.

As shown in FIG. 3B, when the release lever drive member 8 connected to the lever of the belt lock member separates from the release lever of the cam buckle, the locking teeth bite into the belt due to the built-in spring of the cam buckle, and the belt moves to the cam buckle 20. It is locked to and the movement of the belt is prevented.

Here, a cam buckle, which is a belt locking means, will be described with reference to FIG. 4 (A) is a cross-sectional view, and FIG. 4 (B) is a perspective view. The cam buckle 20 accommodates a front retaining member 23, a rear fastening member 24, locking teeth 25, and the like in a space formed by a side wall constituting a locking tool and a bottom slab. The torsion spring 22 urges the locking teeth 25 toward the front retaining member 23, and lifts the release lever 21 that moves the locking teeth. When the release lever 21 is lifted by the torsion spring 22, the belt is locked and the downward movement of the belt in the longitudinal direction is prevented.

When the belt is pulled downward with the belt between the locking teeth 25 and the front retaining member 23, the locking teeth 25 bite into the belt due to the movement of the belt, so that the belt is prevented from moving downward. On the contrary, if the belt is pulled upward with the belt between the locking tooth 25 and the front retaining member 23, the locking tooth 25 is separated from the front retaining member 23 by the movement of the belt, so that the belt can be moved upward. become. Therefore, when the release lever 21 is pushed from the outside in the direction of the arrow in FIG. 4A, the locking tooth 25 is separated from the front retaining member 23 and is locked between the locking tooth 25 and the front retaining member 23. The belt becomes movable.

The ratchet mechanism used for the fastener will be described with reference to the cross-sectional view shown in FIG. A ratchet gear A12 is coaxially connected to the reel that winds up the belt. The ratchet gear B13 that meshes with the ratchet gear A12 is coaxially connected to the rotating shaft 16 of the belt tightening member so as to be movable in the axial direction. The ratchet gear B is urged in the direction of the ratchet gear A by the compression spring 17 mounted on the rotating shaft 16 and is engaged with the ratchet gear A. When the lever of the belt tightening member 2 rotates in the belt tightening direction, the rotation of the belt tightening member is transmitted to the reel by the ratchet gear B15 engaged with the ratchet gear A12.

In FIG. 5, the ratchet gear A is engaged with the ratchet gear B15, but the ratchet gear B15 is combined with a gear having an oblique inclination on only one side so as to idle when the ratchet gear B15 rotates in the direction of loosening the belt. It is a running face type ratchet.

FIG. 5 shows the angle control groove 122. The angle control groove 122 controls the rotation of the belt tightening member within the range where the angle control groove 122 is provided by fitting the angle control protrusion 121 described later. The angle control groove 122 is provided along the inner inner circumference of the disk member 19 and also exists on the opposite inner peripheral surfaces. This is in consideration of the case where the disk member is attached to the opposite side surface of the fastener 10. The angle control groove 122 has a length corresponding to about 100 degrees of the rotation angle of the belt tightening member 2.

The ratchet gear B is held on the rotating shaft 16 so as to be movable in the axial direction, and is driven by a drive projection 18 provided on the disk member 19 to rotate. A spiral spring 171 is built in the reel to urge the fastening belt 3 in the tightening direction.

A state of incorporating the ratchet mechanism into the fastener will be described with reference to FIG. The ratchet gear A12 is connected to the reel so as to rotate coaxially with the reel. When the lever of the belt tightening member at the belt feeding position is turned in the direction of the arrow shown in FIG. 6 (A) (the direction in which the belt is loosened), the ratchet gear A and the ratchet gear B do not engage with each other due to the inclination of the ratchet gear, and the belt tightening member. The lever of is moved to the vicinity of the standby position. When the lever of the belt tightening member is in the standby state, the ratchet gear A and the ratchet gear B are separated so that the ratchet mechanism does not work and the belt can be freely put in and taken out.

Therefore, the ratchet mechanism disconnection means will be described. A ride-on member 13, which will be described later, is provided on the surface of the ratchet gear A. Further, a riding member 14 corresponding to the riding member 13 is provided on the outer periphery of the ratchet gear B. When the lever of the belt tightening member is turned in the direction of the arrow shown in FIG. 6 (A) and the lever of the belt tightening member is near the standby state, the riding member 14 rides on the mounted member 13 and the ratchet gear B separates from the ratchet gear A. The drive of the reel by the belt tightening member is released, and the belt can be freely unwound or rewound. Here, the separation of the ratchet gear A and the ratchet gear B can be realized by another mechanism that detects the lever in the standby state and pushes the ratchet gear B back to the disk member.

FIG. 7 will explain how the ratchet gear A and the ratchet gear B are engaged with each other due to the rotation of the ratchet gear B. In FIG. 7A, when the riding member 14 moves in the direction of arrow A, the riding member 14 hits the inclined surface of the mounted member 13 and moves in the direction of arrow B. Then, the engagement between the ratchet gear A and the ratchet gear B is released, and mutual interference is eliminated. The state of FIG. 7B corresponds to the standby state of the lever of the belt tightening member 2, and since the rotation of the ratchet gear B is stopped by the stopper mechanism (not shown here), the state of the lever of the tightening member 2 is in the standby state of the reel. Rotation is free in either direction of feeding or rewinding the belt. Therefore, when the belt is pulled out from the reel and the belt is hung on the luggage, the extra length of the belt is rewound by the spiral spring built in the reel.

The rear fastening member shown in FIG. 8 includes a rear fastening member provided at the end of the housing of the fastener, and a member having a sharp tip, for example, a screw. Then, the screws bite into the material such as the flat trolley, so that the rear fastening member is prevented from coming off. This also applies to the front fastening member. Further, it is preferable to cover this member with a soft member in order to prevent injury caused by the member having a sharp tip.

FIG. 9A is an appearance of the fastener 10 according to the present invention. Since the belt is built-in, the length of the belt can be easily adjusted according to the size of the luggage. Further, by moving the lever in the feeding direction of the belt by the belt tightening member, the belt hung on the luggage can be easily tightened.

FIG. 9B shows a fastening method in which the fastener 10 according to the present invention is applied to a flat trolley to prevent the load loaded on the flat trolley from collapsing. The end of the belt pulled out from the fastener is attached to the end of the flat carriage by the front fastening member 5.

By using the fastener of the present invention, the predetermined fastening belt can be easily tightened, which has a great economic effect on the distribution industry.
