The buckle member includes a central member disposed between two side locks. The free end of the central member has a tenon, and the socket has a tenon hole defined in a position corresponding thereto for being matched with the tenon, so as to provide the side release buckle with a central lock, thereby greatly increasing pull-resistance thereof. The side lock further has a wedge-shaped block extended toward the central member. When a pressure is applied to the side locks, the slope of the wedge-shaped enables the free end of the central member to move, thereby making the tenon departed from the tenon hole and releasing the side and central locks.

Description

1247591 V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a side opening buckle, and more particularly to a side lock that is added to the side of the two side latches to increase the tensile strength thereof. Open buckle. [Prior Art] It is well known that webbing has numerous applications. Common examples are pet collars, harnesses, baby bags, backpack climbing, queen towels, skates, life jackets, goods and Passengers are tied up and used, and they have achieved great success in the market. As for the ribbons, the ability to use this wide-ranging and successful product depends on the buckle. As shown in the first figure, it is a typical buckle because it is unbuckled from the side, hence the name side release buckle. The conventional side opening buckle 50 includes a matable fastener 5 1 and a socket 5 2 having an axially extending two side lock members 53_ 53b and usually having a side lock member The central member 54; the socket 52 includes a slot 5 5 ' for receiving the fastener 5 and a notch 5 6 5 b formed on the two sides. When the fastener 5 1 is fully inserted into the socket 5 2 , the elastic restoring forces of the two side lock members 5 3 a and 5 3 b can cooperate with the notches 5 6 a and 5 6 b, thus the fastener 5 1 and Socket 5 2 phase lock. When the two side lock members 53b are pressed, the side lock members can be released from the notches 56a and 56b, and the buckles of the fasteners 5 1 and the sockets 5 2 can be released. The conventional side opening buckle is generally plastic injection molding (i] Q ject i〇n molding), and the material itself has a limited tensile strength. On the other hand, in order to make the two side lock members 53a #n 53b easy to apply pressure and buckle, the cross-sectional area thereof should not be too large. Therefore, the side lock members 5 3 a and 5 3 b are generally the most fragile portions of the conventional side opening buckles 50. Once the side opening buckles 50 are subjected to the tensile force exceeding the resistance of the side lock members 53a and 53b

When the pet belt is used, the irrational collision is so sudden. Collision and injury Although the cross-sectional area of the material lock can be unlocked, this will make the tripping action. As for the ability to use, but the material [invention] According to the middle latch between the lock members of the invention, when the socket is seated, the two side latches of the inventor can lose the lock belt because of the side. It must withstand a small pulling force that can satisfy the need to suddenly suffer from two sides that are prone to breakage. The intensity does not change and the side is opened to make it less powerful. The flatness of the A flat is not broken. This is a woven business. Some of them only need to bear the general dog once, only hit, or hurt. Resistance can be used to change the buckle function for the change. The cooperation of the buckles makes them wide and some of them do not need to withstand the tension, and some have a large pulling force. Therefore, for the side opening buckle, only the two sides are required. However, when the side-opening buckle is applied to the surrounding environment, the side-opening buckle that produces the buckle is often unbearable and tripped, and the result may be caused by increasing the tensile strength of the two side buckles in the case of the dog. However, users who increase the hardness of the side and need to exert greater force, such as children, are not within the scope of the discussion of the invention of a simple and effective square material. It has been found that the conventional fasteners usually have a two-sided central member, and a boring is provided at a corresponding position at the free end of the central member; A central locking buckle, combined with the existing, can greatly improve its tensile strength. Found that if the side locks extend toward the central member, a wedge

Page 6 1247591 (3) Yes, the central member and the central part of the present invention are capable of pulling the buckle of the present invention. When the side lock is inserted into the side lock from the end and facing the center, the wedge is used to disengage the cassette. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT The detailed description of the embodiments of the present invention is shown in FIGS. 3 to 5 and a socket 4 0; the joint 2 1 is usually penetrated by a belt (not shown) to prevent the webbing from slipping. The two side locks that are extended are locked at the free end of the pressure. The purpose of Ming is not only the purpose of the knot, but also the card between the pieces can be unwound. When the socket is used, the bevel of the wedge block can be used to break away from the blink, and the same kind of temple can overcome the ingenuity of the conventional technology. a central locking lock/fastener that can be inserted into the socket; the fastener member eight has a central member having a bore provided in the 'boring hole, and forming a middle wedge member that can be pressed The free end side of the central member and the central latch. And the feature reference to the following white 0. The side opening buckle 1 20 of the present invention has a webbing connection portion and a second belt hole 23a #u 23b to ensure sufficient friction, and the front portion and the second side of the self-joining portion 21 are included. The side lock member 5, the invention describes the shape block; by causing the middle side to be released, the side buckle is opened, and the lifting surface is resistant to the socket and the two sides are completely locked by the self-fastening member. The movement of the side side lock member, as for the embodiment of the drawing type, such as the first fastening member 2 1, the connection forms a movement for the woven fabric to extend the side edge of the tensioning member at the lower end of the pulling force, so as to provide a structure By using the opening buckle, the central member is freely extracted, and the corresponding position of the seat is caused by the inclined surface of the card insertion member extending one, and the other contents can be completely relieved, and the fastener cross member 22 is separated.
