Description
- 1. Field of the Invention
- The present invention relates to buckles and more particularly, to a front release buckle, in which a front hook of the male buckle member is vertically insertable into the female buckle member into engagement with a hooked portion in the female buckle member. Therefore, the front release buckle of the present invention can bear a strong pulling force in horizontal direction.
- 2. Description of the Related Art
- Conventional front release buckles are commonly comprised of a male buckle member and a female buckle member. These front release buckles are intensively used in backpacks, travel bags, shoulder bags, etc., to join two parts together.
-
FIG. 11 illustrates a front release buckle according to the prior art. As illustrated, the buckle is comprised of a male buckle member A and a female buckle member B. The male buckle member A has a center guide rod A2 forwardly extending from the front side, and two spring arms A1 forwardly extending from the front side and equally spaced from the center guide rod A2 at two sides. The two spring arms A1 each have a front end terminating in a retaining block A3 that defines a barbed engagement portion A4. The female buckle member B has a front open side B1, a longitudinal track B2 disposed on the inside and extending to the front open side B1 on the middle, and two side holes B3 respectively cut through the two opposite lateral sidewalls thereof. The side holes B3 each define a front engagement edge B4. When in use, the center guide rod A2 and the two spring arms A1 of the male buckle member A are inserted into the front open side B1 of the female buckle member B to force the center guide rod A2 into the longitudinal track B2, and at the same time the two spring arms A1 are squeezed in direction toward the center guide rod A2 by the two opposite lateral sidewalls of the female buckle member B. After insertion of the center guide rod A2 into the longitudinal track B2, the spring power of the spring arms A1 of the male buckle member A forces the retaining blocks A3 sideways, thereby causing engagement of the barbed engagement portions A4 of the retaining blocks A3 with the respective front engagement edges B4. - The aforesaid front release buckle is functional, however it still has drawbacks as follows:
- 1. Because the male buckle member A and the female buckle member B are attached together in horizontal direction, the engagement structure between the male buckle member A and the female buckle member B must bear a horizontal pulling force. When an excessively high pulling force is produced, the male buckle member A and the female buckle member B may be separated directly in horizontal direction (the engagement direction). Therefore an improvement in this regard is necessary.
- 2. The male buckle member A is fastened to the female buckle member B by means of engaging the retaining blocks A3 of the spring arms A1 into the side holes B3 of the female buckle member B. The engagement force between the spring arms A1 and the side holes B3 is insufficient to bear a strong pulling force, and the spring arms A1 may be permanently deformed or damaged when the belt is stretched heavily. Further, the retaining blocks A3 may be forced away from the respective side holes B3 accidentally, causing unintentional release of the buckle.
- 3. When fastening the male buckle member A to the female buckle member B, the center guide rod A2 must be accurately aimed at the longitudinal track B2 to ensure accurate positioning. If the center guide rod A2 is not accurately aimed at the longitudinal track B2 when fastening the male buckle member A to the female buckle member B, the spring arms A1 and the center guide rod A2 may be deformed or broken unintentionally.
- 4. Because the spring arms A1 and the center guide rod A2 are suspending at the front side of the male buckle member A, they may be permanently deformed or broken accidentally when the male buckle member A is not fastened to the female buckle member B.
- 5. The structural design of the center guide rod A2 is complicated and the matching precision of the male buckle member A and the female buckle member B is critical, and therefore the fabrication of the front release buckle is complicated, showing a low yield rate.
- Therefore, it is desirable to provide a buckle that eliminates the aforesaid drawbacks.
- The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the front release buckle is comprised of a female buckle member, a male buckle member, a control slide and a spring member. The male buckle member comprises a front hook that is to be inserted vertically downwards into the female buckle member into engagement with a hooked portion of the female buckle member. After engagement between the front hook of the male buckle member and the hooked portion of the female buckle member, the control slide holds down the front hook of the male buckle member in the female buckle member in positive engagement with the hooked portion, therefore the front release buckle of the present invention can bear a high pulling force in horizontal direction.
- According to another aspect of the present invention, the control slide is supported on the spring member. After engagement between the front hook of the male buckle member and the hooked portion of the female buckle member, the spring member immediately pushes the control slide from the open position to the close position to hold down the front hook of the male buckle member in the female buckle member, assuring positive engagement between the female buckle member and the male buckle member and prohibiting vibration and vertical displacement of the male buckle member relative to the female buckle member.
- According to still another aspect of the present invention, the front hook of the male buckle member can be forced into engagement with the hooked portion of the female buckle member or disengaged therefrom only when the control slide has been moved backwards relative to the female buckle member through a certain distance from the close position to the open position, and therefore the front release buckle will not be released accidentally.

When inserting thebottom lug 23 of thecontrol slide 2 into thetrough 13 of the female buckle member 1, thesliding rails 22 of thecontrol slide 2 are moved along the beveled guide faces 16 into thesliding grooves 15 for allowing movement of thecontrol slide 2 relative to the female buckle member 1 along thesliding grooves 15. - Referring to
FIGS. 3˜8 , when fastening themale buckle member 3 to the female buckle member 1, move thecontrol slide 2 along thesliding grooves 15 in one direction to open the hookedportion 11 and the top-open receiving chamber 10 and to simultaneously compress the spring member 4 (seeFIGS. 3 and 4 ), and then insert thefront hook 31 of themale buckle member 3 vertically downwardly into the top-open receiving chamber 10 to force thefront hook 31 into engagement with the hooked portion 11 (seeFIGS. 5 and 6 ), thereafter release thecontrol slide 2. When a user released thecontrol slide 2, thespring member 4 immediately pushes thecontrol slide 2 backwards to its former position to close the top-open receiving chamber 10 and the hookedportion 11 again. At this time, thebottom lug 23 is stopped against thestop block 14, and therefore thecontrol slide 21 is kept in position to hold down thefront hook 31 of themale buckle member 3 in positive engagement with the hooked portion 11 (seeFIGS. 7 and 8 ). - Further, during return stroke of the
control slide 2, thecontrol slide 2 is guided by the smoothly archedfront guide face 311 of thefront hook 31 into position to hold down thefront hook 31 of themale buckle member 3 in the top-open receiving chamber 10 of the female buckle member 1 in positive engagement with the hookedportion 11.
