Abstract
A safety buckle assembly including a male member and a female member that interlockingly and releasably engages the male member. The buckle male member is disengaged from the female member by squeezing the side latches towards each other, to disengage the same from the side catches, while simultaneously pressing the push release button such that the central latch is disengaged from the central catch formed in the female member.
Description




BACKGROUND




The present invention relates to buckles, and in particular to a snap buckle for releasably connecting straps, belts or the like, that includes various safety features that prevent inadvertent and unwanted release.




Safety straps are traditionally secured to grocery store carts or other similar vehicles to provide a seatbelt-type restraint in an effort to assure the safety of an occupant or item that is being transported in the shopping cart. Such devices are securely attached to the shopping cart in a manner such that the safety buckle does not become accidentally detached from the cart. Additionally, buckles are used to secure loads carried by various item containers such as backpacks, luggage, fanny packs, etc. The aforementioned devices typically utilize a conventional side release buckle wherein a male member having one or two side latching arms is coupled to a female member that has complimentary catches that enable the male and female members to interlockingly engage one another to secure the system.




Due to the type of systems that these side release buckles are utilized in, the buckles may be subject to various pressures on one or both sides thereof. In these conventional systems, pushing inwardly on one or both of the side latching arms such that the catches release the latches effects disengagement of the securement device. Due to the resiliency of the side latching arms, the disengagement of the side latching arms from the catch cause the side latching arms to spring back to their original position. This resilient force forces the male member to accelerate in an outwardly direction resulting in the male member sliding out of the guide channel of the female member. Furthermore, young children may try to disengage the buckle resulting in a risk to injury to the child.




Thus, a buckle with a safety feature, that is both difficult for a young child to disengage and resistant to unwanted and inadvertent disengagement due to external forces exerted on the buckle, is needed.




SUMMARY




The present invention provides a safety buckle assembly that incorporates structural features that enable a strong and reliable coupling between the male and female members of the clip assembly. Due to these structural features, unwanted and inadvertent disengagement of the male member from the female member that may result in harm or damage to the occupants and/or items secured by the buckle is minimized.




According to the present invention, there is provided a safety buckle assembly comprising a male member that interlockingly and releasably engages a female member. The male member includes a base wall that has a pair of side locking arms each having a latch, a central locking arm having a latch, and a plurality of forming ribs extending therefrom. The central locking arm is longer in length than the side locking arms to afford the central locking arm greater resiliency and flexibility. The female member includes a receiving cavity, that receives the male member when the buckle is fastened, a push button release that engages the central locking arm, two opposing side catches that engage the side locking arm latches, a central catch that engages the central latch, and an opening that enables a user to disengage the buckle assembly in an alternative fashion. Two parallel guiding walls are formed in the cavity and used to guide the central locking arm when the male member engages the female member. The correct orientation of the buckle assembly is assured due to the engagement of the forming ribs with projections that extend from the cavity of the female member when the buckle assembly is fastened.











Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of example.

400


. The buckle assembly


100


including the male and female members


200


,


400


may be molded from a variety of extrudable materials. These may include LDPE, HDPE, ABS, polystyrene, polypropylene, acetates, butyrates, nylons, polyphenylene sulfides, acetals, polycarbonates, thermoplastic rubbers, and polyesters, among others.




As shown in

FIG. 2

, the male member


200


generally includes a handle


202


, and an engagement portion


204


, wherein handle


202


is separated from engagement portion


204


by a base wall


206


. The handle


202


has a generally rectangular shape and is formed by a sloping back wall


208


that is spaced from and parallel to base wall


206


, and two opposing side walls


210


,


212


that connect base wall


206


to back wall


208


to define an opening


214


therebetween. Connected to side walls


210


,


212


is a bar


216


that traverses opening


214


and configured to retain a strap, belt, or some other form of elongated member such as a member


490


shown in FIG.


4


.




The engagement portion


204


generally includes base wall


206


and a plurality of projections that extend therefrom including two side locking arms


218


,


220


, a central locking arm


222


, and a plurality of forming ribs


240


,


242


,


244


, and


246


. Each of the side locking arms


218


,


220


includes an extension member


223


,


224


and a latch element


226


,


228


, respectively, that is disposed on the distal end of each extension member


223


,


224


. The side locking arms


218


and


220


are configured to be resilient in relation to base wall


206


. In this manner, side locking arms


218


and


220


bend horizontally in the directions of arrows


230


and


232


, respectively, when a sufficient amount of force is exerted upon them. As seen from

FIG. 2

, a diameter D of latch elements


226


and


228


is sufficiently larger than a diameter d of extension members


223


and


224


such that a user may be able to manipulate side locking arms


218


and


220


with ease when engaging or disengaging the buckle assembly. Additionally, latch elements


226


and


228


each include a sloping surface


248


and


250


, respectively, that is configured to engage female member


400


during the engagement process of buckle assembly


100


. Latch elements


226


and


228


also include engagement surfaces


252


and


254


, respectively, that are configured to engage complimentary catches formed in female member


400


, discussed below.




The central locking arm


222


includes a groove


234


located therein that runs substantially the entire length of locking arm


222


. A central latch element


236


, encircled by the dotted line shown in

FIG. 2

, is disposed on the distal most end of central locking arm


222


. The central locking arm


222


is configured to be resilient in relation to base wall


206


in that central locking arm


222


bends in a vertical direction indicated by arrow


238


when a sufficient amount of force in the direction of arrow


238


is exerted upon it. As shown in

FIG. 2

, central locking arm


222


has a length L that is longer than a length l of the side locking arms


218


and


220


. The length L affords central locking arm


222


a high degree of flexibility and a large contact surface when the buckle system is engaged. The combination of the large contact area and the high degree of flexibility effects a more reliable and secure engagement between male member


200


and female member


400


. The central latch


236


will be described in more detail with reference to

FIG. 3

, discussed below.




Forming ribs


240


,


242


,


244


, and


246


each extend from base wall


206


and are configured to be relatively stiff. Forming ribs


240


and


242


are disposed between and spaced equidistantly from side locking arm


218


and central locking arm


234


. Similarly, forming ribs


244


and


246


are disposed between and spaced equidistantly from side locking arm


220


and central locking arm


234


.




Referring to

FIG. 3

, a more detailed description of central latch


236


will be given. Central latch


236


of the central locking arm


222


includes a recess


302


, a sloping surface


304


, and a wall


306


. As shown in

FIGS. 2 and 3

, recess


302


is disposed at the most distal end of groove


234


, and has a substantially planar surface. Recess


302


is separated from groove


234


by a downwardly sloping surface


304


. Therefore, recess


302


, bordered by sloping surface


304


and wall


306


, forms central latch


236


that is configured to retain a catch formed on the female member


400


, discussed below.




Female member


400


will be discussed with reference to

FIGS. 4 and 5

. Female member


400


generally consists of a body


402


and a strap retaining portion


404


. Body


402


includes a first open end


406


, a second closed end


408


bordered by back wall

420


and


422


, opening


424


, guiding walls


426


and


428


, and a central catch


430


shown in dotted lines.




Open end


406


is defined by a lower surface


432


, an upper surface


434


, and two side surfaces


436


and


438


that join lower surface


432


and upper surface


434


. A cavity


440


is defined between open end


406


and back wall


410


of the body. Projections


412


,


414


, and


416


are formed in most proximal edge of lower surface


432


are configured to fittingly engage forming ribs


240


,


242


,


244


, and


246


when the buckle assembly is engaged. Guiding walls


426


and


428


are disposed on lower surface


432


of body


402


and are substantially the same length as cavity


440


. Guiding walls


426


and


428


are configured to engage central locking arm


222


when male member


200


is inserted into female member


400


. In a preferred embodiment, guiding walls


426


and


428


are connected to back wall


410


for a more stable buckle system.




Side surfaces


436


and


438


have sloping surfaces


446


and


448


, respectively, formed therein that are configured to engage side locking arms


218


and


220


when male member


200


is inserted into female member


400


. Side catch


420


is defined by an opening


442


formed in the sloped surface


446


of side surface


436


. Similarly, side catch


422


is defined by an opening


444


formed in sloped surface


448


of side surface


436


. Side catches


422


and


420


are configured to interlockingly engage latch elements


226


and


228


, respectively, when the buckle assembly is engaged.




Central catch


430


is formed on and extends from upper surface


434


a distance into the cavity


440


of body


402


. Central catch


430


is configured to engage central latch


236


of central locking member


222


when the buckle assembly is engaged. Push release button


418


is formed on upper surface


434


of body


402


and includes an upper free end


450


and a lower fixed end


452


wherein upper end


450


is translatable, in a downward direction in relation to a fixed lower end


452


, when a downward force is exerted thereon. Push button


418


is configured to resiliently engage central locking member


222


in an effort to disengage male member


200


from female member


400


. In a preferred embodiment of the present invention, push release button


418


is formed in a circular configuration to more comfortably accommodate a user's finger upon actuation of button


418


. However, push button


418


may embody any other convenient shape that is suitable for its purpose.




Strap retaining portion


404


of female member


400


includes a strap retaining bar


458


, shown in dotted lines, that is configured to retain a strap, belt, or some other form of elongated member such as the member


490


shown in FIG.


4


. Opening


424


is a substantially rectangular opening formed in upper surface


434


of body


402


and configured such that wall


306


of central latch


236


is visible to a user looking at upper surface


434


of engaged buckle assembly


100


in a downwardly direction, such as seen in FIG.


1


. One example of the operation of the opening


424


will be discussed below with reference to disengaging the buckle assembly


100


of the present invention.




With reference to

FIGS. 2-7

, the engagement of buckle assembly


100


will be described in detail. During the operation of fastening the buckle assembly, engagement portion


204


of male member


200


is aligned with cavity


440


of female member


400


such that the distal end of central locking arm


222


is inserted between guiding walls


426


and


428


and latch elements


226


and


228


of side locking arms abut side surfaces


438


and


436


, respectively. At this point, an engagement force is exerted upon the male and female members


200


and


400


such that side locking arms


218


and


220


are moved in the direction of arrows


230


and


232


, respectively, as a result of the enlarged diameter D and sloped surfaces


248


and


250


of latch elements


226


and


228


, respectively, engaging side surfaces


438


and


436


. At this point, a greater portion of the length L of central locking arm


222


is positioned in cavity


440


, between guiding walls


426


and


428


, with central latch


236


positioned just proximate of central catch


430


, as shown in FIG.


5


. At this point, engagement portion


204


of male member


200


has resiliently conformed to the shape of first open end


406


and cavity


440


of female member


400


such that latch elements


226


,


228


, and


236


may slide into alignment with complimentary side catches


422


,


420


and central catch


430


, respectively. As male member


200


is further inserted within female member


400


, wall


306


of central locking arm


222


engages a sloping surface


502


of central catch


430


and is forced in a downward direction, as shown in FIG.


6


. At this point, a distal portion of sloping surfaces


248


and


250


are adjacent to openings


444


and


442


, respectively. Additionally, projections


416


and


414


are in alignment with forming ribs


240


and


242


. Similarly, projections


414


and


412


are in alignment with forming ribs


244


and


246


.




Continuation of the engagement force upon male and female members


200


and


400


results in wall


306


of central latch


236


being pushed over the distal most part of slope surface


502


resulting in central locking arm


222


resiliently moving in an upward direction, back to its original state, as seen in FIG.


7


. Thus, central catch


430


is retained between wall


306


and sloping surface


304


. Additionally, latch elements


226


and


228


are positioned adjacent to openings


444


and


442


, respectively, in a manner such that engaging walls


252


and


254


are adjacent to openings


444


and


442


, respectively. Therefore, the forces exerted on sloping surfaces


248


and


250


by side surfaces


438


and


436


, respectively, cease to exist allowing latch elements


226


and


228


to fill openings


444


and


442


. Due to the resiliency of side locking arms


218


and


220


, side locking arms


218


and


220


resume their original position in relation to central locking arm


222


. In this manner, engagement surfaces


252


and


254


engage side catches


422


and


420


. Furthermore, projections


416


and


414


engage forming ribs


240


and


242


, respectively, and projections


414


and


412


engage forming ribs


244


and


246


.




In this manner, a secure buckle arrangement is effected due to the mating of side catches


422


and


420


and central catch


430


of female member


400


with latches


226


,


228


, and


236


, respectively, of male member


200


. Additionally, a proper engagement of male member


200


with female member


400


is assured due to the forming ribs engagement to projections


412


,


414


, and


416


. For example, if male member


200


is inserted into female member


400


in a reverse manner such that sloping surface


248


engages side surface


436


and sloping surface


250


engages side surface


438


, forming ribs


240


,


242


,


244


, and


246


would engage the most proximal surface


454


of upper surface


434


. This engagement would prevent latch elements


226


,


228


and


236


from engaging catches


422


,


420


, and


430


, respectively, thus prohibiting the securement of male member


200


to female member


400


.




The disengagement of buckle assembly


100


will now be described in detail with reference to

FIGS. 1-4

,


8


and


9


. To disengage male member


200


from female member


400


, a force must be exerted upon latches


226


and


228


to push them towards one another in the direction of arrows


230


and


232


. The movement of latches


226


and


228


in this direction releases engagement surfaces


252


and


254


from side catches


422


and


420


, respectively. This operation is well known in the art and thus will not be described in any further detail. In addition to the force exerted upon latch elements


226


and


228


, a simultaneous downward force must be exerted upon push release button


418


to disengage central latch


236


from central catch


430


. Once a sufficient force has been exerted upon push button


418


, central locking arm


222


will be forced in a downward direction through the actuation of push button


418


upon central locking arm


222


, as seen in FIG.


8


. Once latches


226


and


228


, and central latch


236


have been disengaged from side catches


422


and


420


, and central catch


430


, respectively, a disengagement force may be exerted upon male member


200


and female member


400


that effectively pulls male member


200


and female member


400


in opposite directions to effect disengagement of the buckle assembly


100


. Due to the requirement of disengaging three latches from their respective catches before the buckle assembly may be disengaged, the accidental disengagement of the buckle assembly due to external forces on one or two latches included in the buckle assembly is averted. Due to the design of the buckle assembly


100


, a user may use one hand to facilitate the disengagement of the male member


200


from the female member


400


.




As seen in

FIGS. 1 and 4

, push release button


418


is formed substantially in the center of upper surface


434


and central catch


430


is disposed close to back wall


410


, intermediate push release button


418


and back wall


410


. Due to the length L of central locking arm


222


and the placement of central catch


430


within cavity


440


of female member


400


, push release button


418


engages central locking arm


222


at a point substantially in the center of central locking arm


222


, as seen in

FIG. 8

, during the disengagement of buckle assembly


100


. Those having skill in the art can appreciate that the combination, of the placement of push release button


418


, central catch


430


, and central latch


236


, and the manner in which push release button


418


engages central locking arm


222


, allows for a very stable disengagement of buckle assembly


100


.




In a second embodiment of the present invention, a second method of disengagement of male member


200


from female member


400


may be affected. In this embodiment, opening


424


may also be used to disengage central latch


236


of central locking arm


222


from central catch


430


. The opening has the further benefit of being configured to enable the addition of structural features to the female member during and after manufacturing. These features may include the internal central catch


430


, or other features that may be desired. The emergency disengagement method of the present invention will now be described in detail. Opening


424


is configured such that it physically borders central catch. Additionally, the dimensions of opening


424


are such that wall


306


of central locking arm


222


may be clearly seen and manipulated to effect the release of central latch


236


from central catch


430


. To effect this end result, an external actuator


900


that has a distal configuration comparable to the dimensions of opening


424


may be used to exert a downward force on wall


306


of central locking arm


222


such that central catch


236


disengages central latch


430


, as seen in FIG.


9


. At this point, the disengagement of male member


200


from female member


400


is accomplished by the simultaneous disengagement of side catches


422


and


420


from latch elements


226


and


228


in the same manner as described above. In this manner, if push release button


418


were to ever become inoperable, the buckle assembly of the present invention may be disengaged by utilizing a second method that is fast, safe, and reliable while ensuring that the operation of buckle assembly


100


is not compromised any further. To this end, emergency release opening


424


gives a user an alternative method to release buckle assembly


100


without damaging the assembly any further.





FIG. 10

illustrates an alternative embodiment of the present invention. Referring to

FIG. 10

, a buckle assembly


1000


is shown wherein a male member


1200


is interlockingly engaged to a female member


1100


. In this embodiment, a push release button


1002


is formed in a top surface


1004


and has a free end


1006


that faces male member


1200


and a fixed end


1008


that faces a strap retaining bar


1014


. A central catch


1010


, shown in dotted lines, is formed intermediate push release button


1002


and proximal end


1012


of female member


1100


.





FIG. 11

illustrates a bottom view of buckle assembly


1000


shown in FIG.


10


. In this embodiment, opening


1102


is formed in a bottom surface
