Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a belt-like material which is used in a bag such as a rucksack or a school bag, and which can be attached and detached very easily as required. It relates to a coupling device. 2. Description of the Related Art Conventionally, as a means for attaching and detaching a belt such as a rucksack or a school bag, a pair of main and sub-belts to which upper and lower outer ends of the back of the rucksack and the school bag are attached are provided. One of the opposing ends is generally provided with a plurality of holes at appropriate intervals, the other is provided with a connecting member that fits into this hole and connects each other, and when it is desired to remove the primary and secondary belts, disconnect each connection, In general, it is possible to adjust the length of the entire belt by changing the position of the hole into which the connecting member is fitted. [0003] However, this type of connecting means is a reliable means for connecting the connecting member of the sub-belt to the hole of the main belt, but encounters an unexpected accident or emergency. At that time, it was not suitable for disconnecting the belt. SUMMARY OF THE INVENTION An object of the present invention is to secure the fastening of the wearer in a normal state and to protect the safety of the wearer, but also in the case of an emergency or the like. It is an object of the present invention to provide a belt which can be easily and reliably removed with a so-called one-touch operation. [0005] The features of the present invention are:
There is a pair of main and sub-belts (1) and (2) whose opposite ends are detachable. The main belt (1) has one end fixed to its surface and the other end can perform a fan-shaped movement. A belt (3); a swingable latch (4) suspended from the back surface of the belt (3); and a swingably attached to the surface of the main belt (1). The auxiliary belt (2) is slidably attached to the end facing the main belt (1). A second connection fitting (6) that can be engaged with the connection fitting (5). The first connecting member (5) and the second connecting member (2) are further engaged, and the connecting member (5) and the latching member (4) are also securely connected. In the engaged state. Here, when it is necessary to quickly disengage them in an emergency or the like, the operation belt (3) is pulled. As a result, the operation belt (3) and the first connection fitting (5) are disengaged, and then the first connection fitting (5) and the second connection fitting (6) are disengaged. The engagement of the belt (2) can be easily released. According to the connecting device for a belt-like object of the present invention, the connecting means for connecting the main belt (1) and the sub-belt (2) is different from the conventional device for connecting a belt-like material. Metal fittings (5)
Since this is a means for engaging with the latch (4) in addition to the engagement of (6), the connection is assured. To release this connection, the operation belt (4) provided on the latch (4) is simply used. 3) could be easily solved by a so-called one-touch operation of merely performing a fan motion. Others The present invention has other objects, excellent structural features, and excellent functions and effects, which will be clarified in the following embodiments. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, (1) and (2) show a pair of main belts whose opposite ends are detachable. The outer ends of the belts are sewn on upper and lower sides of a bag such as a rucksack or a school bag worn by the wearer, if not shown, though not shown. Since the material of the main and sub belts (1) and (2) is in wide direct contact with the wearer's shoulder, it is the same as that for molding bags such as rucksacks if a temporary command is made so as not to cut into the shoulder. Is preferred, but the invention is not limited to this. Any material such as a rubber material that stretches elastically or a high-quality leather material may be used. An operation belt (3) is fixed at one end to a surface near an end of the main belt (1), and is open at the other end so as to be able to perform a fan-like movement. A male part (10) of the button is provided protruding from the rear side surface near the part. [0013] On the back surface of the end portion of the operation belt (3),
There is a first hook fitting (12), and a swingable latch (4) is suspended. That is, the latch (4)
As shown in FIG. 1, the distal end has a through hole (41) that can be engaged with the first hook fitting (12), and the distal end has a pair of arrows each having an outward spring force. There is a shape engaging claw piece (42). The positional relationship between these members is such that when the end of the operation belt (3) is moved upward in a fan-like manner in the figure, the first hook fitting (12) on the back surface thereof and the hook suspended therefrom. The stopper (4) can also be linked. Further, a second hook fitting (51) is provided on the end surface of the main belt (1), and the engaging hook piece (4) of the hook fitting (4) is provided on the fitting (51). A first connection fitting (5) which can be securely engaged with the first connection fitting (42) is pivotally mounted. A sub-belt (2) is provided with a third hook (61) at an end of the main belt (1), and a second hook (61) capable of engaging with the first connecting metal (5). A connection fitting (6) is pivotally mounted. Further, a female button (11) is provided at a position on the surface of the sub-belt (2) where the male button (10) of the main belt (1) can be engaged. A pair of male and female buttons (10) (11)
Any known button can be used as long as the combination can be released by the wearer's own force, and any button having a similar function, such as a hook, a fastener, or a magic tape (registered trademark), may be used as long as the command is issued. Next, the operation of the apparatus for connecting strips having the above-described configuration will be described. Therefore, first, the first connecting metal fitting (5) provided on the main belt (1) is inserted vertically into the second connecting metal fitting (6) provided at the tip of the sub-belt (2). However, in this case, the upper side of the connecting metal fitting (5) should be spaced from the second connecting metal fitting (6). When the engaging claw (42) of the latch (4) provided with the operation belt (3) is inserted into the space, the engagement is completed as shown in FIG. Since the stopper (4) has an arrow shape having an outward spring force, the stopper (4) is engaged with both side surfaces of the first connecting member (5) so as not to be easily pulled out. In order to prevent such a connection from being released due to a scandal, a pair of male and female buttons (10) and (11) provided on the main belt (1) and the sub-belt (2) as shown in FIG. Hang it. Subsequently, these engagement relationships are determined by the operation belt (3).
The operation of releasing by a so-called one-touch operation only by rotating (fan-like movement) is described. First, the wearer pulls the operation belt (3) relatively vigorously in an upward fan shape. As a result, the male and female buttons (1) of the main belt (1) and the sub-belt (2)
0) and (11) are disengaged, and the action of the movement causes the latch (4) provided on the operation belt (3) to interlock, so that the latch (4) and the first connecting bracket (5). And the main belt (1) also performs a fan-like motion, and the first connecting metal fitting (5) and the second connecting metal fitting (6) provided on the sub-belt (2) are locked by the hook. Since the connection is released due to the detachment of the metal fitting (4), there is no means for connecting the main belt (1) and the sub-belt (2). ) (2)
Was able to leave. As described above, according to the present invention, in a case where the main and sub belts (1) and (2) must be released, particularly in an emergency, the so-called "disconnection" can be instantaneously and smoothly performed by one-touch operation. That can be done. [0023] In addition, during normal use, a structure that cannot be easily attached and detached by firmly connecting to each other so as to prevent a possible accident beforehand and to ensure the safety of the wearer. is there.
