This application relates to and claims priority benefits from U.S. Provisional Patent Application No. 61/373,907 entitled “Dual Release Buckle,” filed Aug. 16, 2010, which is hereby incorporated by reference in its entirety.
FIELD OF EMBODIMENTS OF THE INVENTIONEmbodiments of the present invention generally relate to a buckle assembly, and more particularly, to a side-release buckle assembly.
BACKGROUNDA conventional side-release buckle assembly includes a male connection member that is configured to mate with a female connection member, such as shown and described in U.S. Pat. No. 5,465,472, entitled “Buckle.” Each connection member is configured to retain a strap, such as a seatbelt or backpack strap. The male connection member includes integral buttons that may be engaged to release the male connection member from the female connection member, thereby disconnecting the buckle assembly.
In order to secure the male connection member 12 into the female connection member 14, the male connection member 12 is urged into the female connection member 14 in the direction of arrow B. A guide beam 26 of the male connection member 12 moves into a reciprocal channel (not shown) formed in the female connection member 14 to ensure proper mating alignment between the male and female connection members 12 and 14, respectively. As the male connection member 12 is urged into the female connection member 14, the lateral arms 16 deflect inwardly in the directions of arcs A and A′ until the buttons 18 reach button openings 28 formed through the female connection member 14. When the buttons 18 enter the button openings 28, the tension stored in the lateral arms 16 snapably forces the lateral arms 16 and the buttons laterally outward, so that the buttons 18 are secured within the button openings 28. At this point, the male connection member 12 is secured to the female connection member 14.

Additionally, with increased use, the resiliency of the lateral arms 16 may diminish. Indeed, in certain conditions, such as extreme cold, the lateral arms 16 may even snap or otherwise break.
SUMMARY OF EMBODIMENTS OF THE INVENTIONCertain embodiments of the present invention provide a buckle assembly that includes a female connection member having a main body defining an internal chamber and first and second button openings, and a male connection member selectively connected to the female connection member. The male connection member includes opposed first and second buttons selectively retained within the first and second button openings, respectively, and a pull tab operatively connected to the first and second buttons.
The male connection member and the female connection member are configured to be disconnected from one another by the first and second buttons being squeezed toward one another and/or the pull tab being pulled. Linear movement of the pull tab in a first direction may cause relative movement between the first and second buttons in a direction that is perpendicular to the first direction, and vice versa. Similarly, movement of the first and second buttons may cause linear movement of the pull tab.
The male connection member may include first and second coil springs. The first coil spring may be disposed between the first button and the pull tab, and the second coil spring may be disposed between the second button and the pull tab.
The male connection member may also include a rigid housing that prevents the first and second buttons from moving in a direction that is parallel to a longitudinal axis of the pull tab.
The pull tab may include at least one post slidably retained within at least one angled track formed through at least one of the first and second buttons. For example, the pull tab may include an extension beam having a first post extending from a first surface and a second post extending from a second surface opposite the first surface. The first post may be slidably retained within a first angled track formed through a portion of the first button, and the second post may be slidably retained within a second angled track formed through a portion of the second button. The first button may include first panels and the second button may include second panels slidably retained to the first panels and/or a portion of the pull tab within the male connection member.
Certain embodiments of the present invention provide a male connection member of a buckle assembly that includes a rigid housing connected to a fixed cap through outer beams, wherein the rigid beam defines a central channel. The male connection member may also include opposed first and second buttons movably secured between the rigid housing and the cap, and a pull tab having an extension beam extending into the central channel. The extension beam is operatively connected to the first and second buttons.
The male connection member is configured to be disconnected from a female connection member by the first and second buttons being squeezed toward one another and/or the pull tab being pulled.
The male connection member may also include first and second coil springs. The first coil spring may be disposed between the first button and the extension beam, and the second coil spring may be disposed between the second button and the extension beam.
Certain embodiments of the present invention provide a buckle assembly including a female connection member and a male connection member. The female connection member includes a main body defining an internal chamber and first and second button openings.
The male connection member is selectively connected to the female connection member. The male connection member may include a rigid housing connected to a fixed cap through outer beams, opposed first and second buttons movably secured between the rigid housing and the cap, wherein the first button extends through the first button opening and the second button extends through the second button opening, a pull tab having an extension beam extending into a central channel of the rigid housing, and the extension beam is operatively connected to the first and second buttons. The male connection member may also include first and second coil springs, wherein the first coil spring is disposed between the first button and the extension beam, and the second coil spring is disposed between the second button and the extension beam.
The male connection member is configured to be disconnected from the female connection member by the first and second buttons being squeezed toward one another and/or the pull tab being pulled. Linear movement of the pull tab in a first direction causes relative movement between the first and second buttons in a direction that is perpendicular to the first direction, and vice versa.
Before the embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein are for the purpose of description and should not be regarded as limiting. The use of “including” and “comprising” and variations thereof is meant to encompass the items listed thereafter and equivalents thereof as well as additional items and equivalents thereof.
DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTIONThe female connection member 32 includes an open receiving end 36 configured to receive the male connection member 34. A strap channel 38 is formed at an end 40 that is opposite the receiving end 36. Button openings 42 are formed on opposite sides of the female connection member 32.
The male connection member 34 includes a strap end 44 configured to receive a strap and a female-engaging end 46 that is configured to pass into the receiving end 36 and secure within the female connection member 32. The female-engaging end 46 includes opposed buttons 48 and 48′ that are retained within the button openings 42. Each button 48 and 48′ is bounded on three sides by rigid walls of the female connection member 32. As such, an operator may engage the exposed surfaces of the buttons 48 and 48′ and squeeze them together in order to disconnect the male connection member 34 from the female connection member 32.
The male connection member 34 also includes a moveable pull tab 50 that is operatively connected to the buttons 48. A hole 52 may be formed through an exposed end of the pull tab 50. A looped string may secure within the hole 52 so that an operator may pull on the string to move the pull tab 50. Optionally, the pull tab 50 may include tactile surfaces for an operator to grip.
The extension beam 58 of the pull tab 50 extends into the channel 60. As shown in
The coil springs 56 are compressively secured within each button 48 and 48′ between respective panels 72 and 72′. The coil springs 56 abut into the extension beam 58 and push the buttons 48 and 48′ laterally away therefrom. As shown in
Because the upper panel 72 of the button 48 rests within a recessed area 74′ of the button 48′ above the upper panel 72′, and the lower panel 72′ of the rests within a recessed area 74 of the button 48 below the lower panel 72 (and the upper panel 72′ of the button 48′ and the lower panel 72 of the button 48 slidably engage the extension beam 58 within the channel 60), the buttons 48 and 48′ may be squeezed together in order to reduce the width W of the male connection member 34. When an operator squeezes the buttons 48 and 48′ together, for example, with sufficient force to overcome the spring constant of the springs 56, the buttons 48 and 48′ retract toward a central axis X of the male connection member 34.
In addition to being squeezed by an operator, the button 48 may also be retracted by pulling the pull tab 50 in the direction of arrow A. When the pull tab 50 is pulled in this manner, the post 68 at the distal end 70 of the extension beam 58 follows. As the post 68 moves in the direction of arrow A, the post 68 pulls the button 48 inwardly by way of the angled track 70. That is, as the post 68 moves linearly in the direction of arrow A, it slides over the surfaces of the button 48 that define the angled track 71, thereby pulling the button 48 inwardly. Similar movement is experienced by the button 48′ (not shown in
When an operator ceases to exert a pulling force on the pull tab in the direction of arrow A, the springs 56 (shown in
In order to reconnect the male connection member 34 to the female connection member 32, the cap 64 of the male connection member 32 is urged into the receiving end 36 of the female connection member 32. The buttons 48 and 48′ have beveled leading edges. As such, the buttons 48 and 48′ are able to pass into the female connection member 32 and squeeze together. Once the male connection member 34 is urged to the point where the buttons 48 and 48′ encounter the button openings 42, the force exerted by the springs 56 forces the buttons 48 and 48′ outwardly so that they are retained by the rigid walls of the female connection member 32 that define the button openings.
Thus, embodiments of the present invention provide a buckle assembly that may be easily disconnected through squeezing and/or pulling. If an operator finds it difficult to squeeze the buttons together, the operator may instead pull the pull tab to disconnect the buckle assembly. Embodiments of the present invention provide a robust buckle assembly that does not include long button arms that are susceptible to snapping.
