Abstract

PURPOSE: To get firm coupling of main central part and enable maintaining of stable coupling by wedging a guide member in the corresponding shape projected at a male member into the guide groove in the shape of a wedge made at the center of a female member at coupling. CONSTITUTION: When the tip side of the flexible arm 19 of a male member 1 is inserted into the hollow part 8 through the opening 9 of a female member 2, the outside flanks of both locks 20 abut on the peripheral walls of the hollow parts 8, and both flexible arms 19 bend little inward with each other by elasticity, and advance while sliding on the peripheral walls of the hollow parts 8 in intact condition. At the same time, the guide member 24 also goes on freely without sliding within the guide groove 15 in opposite position, and then, when both flanks of the guide members 24 and both flanks of the guide groove 15 abut on each other, the insertion stops, and both gets in wedged condition, and the wedging on central side in a buckle is performed, and the coupling is completed. At the same time, both locks 20 are positioned in a window part 10, and a lock step 21 reaches the brim of the hole 11 of the window part, and it gets in free condition without restraint by the hollow part 8.

る。In the embodiment shown in FIGS. 16 and 17, the guide grooves 15 and 27 described above are formed in the female member 2 and the guide member 25 is provided so as to project, whereas the male member 3 corresponds to these. The guide members 24 and 28 are provided so as to project, and the guide groove 26
At the end of the connection between the two, the guide grooves 15, 26, 27 form a triple wedge-shaped connection with the guide members 24, 25, 28, respectively, as shown in FIG. Even if the male member 3 is obliquely inserted into the female member 2, the guide member 24 having a long length comes into contact with the guide groove 15 so that the direction is corrected and the guide member 24 is guided to the correct insertion state. Further, for example, the guide member 25 is used as a guide groove formed on the inner surfaces of the side walls 5 and 5, whereas the guide groove 26 is provided to the guide member 2.
It is possible to make changes so as to project into a shape corresponding to the four surfaces.

上する。As is apparent from the above description, according to the present invention, since the wedge-shaped guide groove formed in the center of the female member and the corresponding guide member projecting from the male member are wedge-fitted at the time of connection, A strong connected state on the center side, which is the main body, is obtained, and there is no rattling or horizontal or vertical shake after connection, and a stable connected state can be maintained. Further, during insertion and removal, the guide groove and the guide member do not slide, and the wedged state can be released very quickly and easily, so that the attachment / detachment operation can be performed easily and lightly, and the buckle itself. There is little wear or failure. Moreover, since the guide groove is built in the inner surface of the cylinder, it acts as a rib to improve the strength of the female member.

ある。Further, a small wedge-shaped guide member is projected on the inner side of the guide groove of the female member, and a wedge-shaped guide groove corresponding to the guide member is formed at the tip of the guide member of the male member, so that the central portion at the time of connection. The double-sided wedge-shaped connection between the side and the back side makes it possible to make the connection on the back side of the buckle particularly strong.

とされるバックルが得られる。Further, a small wedge-shaped guide groove is formed on the inlet side of the side wall of the female member, and a wedge-shaped guide member corresponding to the guide groove is projectingly provided at the base of the main guide member at the center of the male member. Thus, a buckle in which the connection on the inlet side is particularly strong can be obtained by adopting a configuration that enables double wedge-shaped coupling on the center side and the inlet side at the time of connection.

保できる。Further, by providing the wedge-side means on the back side and the entrance side, the entire central portion connecting the center side, the back side and the entrance side of the buckle is triple-wedge-joined.
An extremely strong connection is obtained, and rattling and vertical / horizontal wobbling are completely eliminated, and the structure becomes strong, and even if a soft material is used, there is no inconvenience such as deformation or accidental detachment of the flexible arm.
It should be noted that the same effect can be expected by providing the protruding guide member and the guide groove that fits with the protruding guide member in the above-described embodiment on the male member and the female member, respectively. Furthermore, since the deep portion and the inlet are fitted tightly when they are joined and there is no vertical or horizontal deviation, no accidental disengagement of the twisting operation occurs, so an inexpensive soft material can be used. Furthermore, since engagement and disengagement of the male member and the female member are wedge-shaped (tapered), smooth induction fitting and disengagement are possible,
Safety can be ensured because hands, fingers, skin, clothes, etc. are not caught.

In this drawing die, those having parallel sliding contact are formed on the raised portion inside the female member. Since there is an upward slope, the gap between the back and the entrance will be different,
It is difficult to eliminate rattling, but it can be improved by using a wedge structure.
