Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
A buckle assembly and methods of use will now be described in detail with reference to the accompanying drawings. It will be appreciated that, while the following description focuses on an assembly that can buckle straps, the systems and methods disclosed herein have wide applicability. For example, the buckle assembly described herein may be readily employed with clothing, footwear, fabric, tool belts, building materials or anywhere where a removable coupling between elements is desired. Notwithstanding the specific example embodiments set forth below, all such variations and modifications that would be envisioned by one of ordinary skill in the art are intended to fall within the scope of this disclosure.
One Embodiment of the Buckle AssemblyIn one example embodiment, the buckle assembly generally comprises a buckle body and a base body. The buckle body is configured to couple with an article, such as a strap, and be received and retained within the base body. In embodiments, the buckle body is received in the base body from one direction and it is retained in the base body when the buckle body is forced or pulled in another direction. In some embodiments, the buckle body is also secured in the buckle body when a non-removing force is applied to the buckle body while a removing force may remove the buckle body from the base body.
For illustration purposes and not for limitation, one example embodiment of the buckle assembly is shown in
One embodiment of the buckle body generally comprises at least one engaging element. In the embodiment shown in
In some embodiments, there may be different engaging elements. For example, the first engaging element may be provided by a separate element, or a separate portion of another element whereby it provides a shape to engage the base body and retain the buckle body in a first direction. The second engaging element may also be the curved resilient retaining finger as described above.
In some embodiments, as in those shown in
Referring back to the embodiment of
Also shown in the embodiment of
In the example embodiment shown in
Suitable example materials for the buckle body include, but are not limited to plastics, polyethylene (PE), polypropylene (PP) and polycarbonate (PC), acetal, nylon, thermoplastics, thermoset materials, resins, metals, any combination of these materials or any combination with other materials that can provide a flexible engaging element and a buckle body to be retained in the base body when forces are applied to the buckle body.
Referring to
In this embodiment, the base body 360 further comprises a first directional retainer 364 and a second directional retainer 366. The first directional retainer 364 is a separate element or a shaping of the cavity side wall configured to engage a first surface of the buckle body, here a portion of an engaging element, and retain the buckle body in a first direction. The profile of the cavity at the first directional retainer 364 defines the location of the cross-section for the first directional retainer portion profile. The second directional retainer 366 is a separate element or a shaping of the cavity side walls configured to engage a second surface of the buckle body, here a portion of an engaging element, and provide a means to retain the cavity of the buckle body in a second direction whereby the buckle body is retained in the base body 360. The second directional retainer 366 generally defines the location of the cross-section of the second directional retainer portion profile. In some embodiments, as in the one shown, but not in all embodiments, the second directional retainer 366 may define the location of the cross-section for both the second directional retainer portion profile and the receiving portion profile.
The distance between the cavity side walls 370 of the cavity define the cavity width W. The first directional retainer portion, defined between the first directional retainers 364, similar to compression retaining bumps, define a first directional retainer portion having a first directional retainer portion profile including a constraining cavity width W1. The second direction retainer portion, defined between second directional retainers 366 defines a second directional retainer portion having a second directional retainer portion profile including a constraining cavity width W2. The profiles of the two retainer portions are sized such that a first engaging surface 342 of the buckle body can pass through the width W2 but not the first constraining width W1 and the buckle body 320 is constrained in the first direction D1.
As shown in the illustrations of
Referring back to
In some embodiments, when the buckle body 320 is inserted in the base body 360, the second engaging surface 348 is biased to engage the second directional retainer 366 at the second constraining width W2 whereby the buckle body 320 is constrained in the second direction of the third dimension.
As shown in
For this, and for other embodiments, the cavity walls may be shaped to help retain the engaging element. For example, if the engaging elements are rounded, a concave cavity wall shape may help retain the engaging elements.
The flex properties of the engaging element 230 should be sufficient to allow a setting force to be applied to the buckle body 220 relative to the base body and allow it to flex to at least the buckle body receiving profile whereby the buckle body 220 can pass through the second directional retainer portion in the first direction into the base body cavity. The setting force is defined as at least the force necessary to force the engaging elements to flex into the buckle body receiving profile. In some embodiments, the flexing of the engaging elements is provided by cooperating shapes of the base body cavity side walls and the external surface shape of the engaging elements.
The resiliency of the engaging element should be sufficient to allow the engaging elements to be urged into the buckle body set profile and stay in a profile larger than the second directional retainer portion profile when a non-removing force is applied to the buckle body in the second direction. The non-removing force is defined as a force no greater than the force necessary to force the engaging element to flex into the buckle body receiving profile. This resiliency constrains the buckle body in the base body when the non-removing force is applied in the second direction. The resiliency of the engaging element may be influenced by cooperative shapes of the base body cavity side walls and the external surface shape of the engaging elements. The interoperation of the engaging element resiliency and the second directional retainer portion profile provide one embodiment of the means to retain the buckle body in the cavity when the buckle body is forced in the second direction.
The flex properties of the engaging element also allow a removing force to be applied to the buckle body whereby the engaging elements are forced to flex to at least the buckle body receiving profile whereby the buckle body can pass through the second direction retainer portion in the second direction out of the base body cavity. The removing force is defined as at least the force in the second direction necessary to force the engaging elements to flex into the buckle body receiving profile. The removing force may be influenced by cooperative shapes of the base body cavity side walls and the external surface shape of the engaging elements.
In some embodiments, the buckle body may further comprise a pusher portion 258. As shown in
The suitable embodiments of
Suitable materials for the base body include, but are not limited to those described for the buckle body. In addition, the base body may be made of more rigid materials than the buckle body including any materials that can provide rigidity and strength in the cavity to retain the buckle body when forces are applied.
In another embodiment of the buckle assembly shown in
In another embodiment, as shown in
As shown in
In another example embodiment, as shown in
Operation of one embodiment of the buckle assembly generally comprises the steps of inserting the buckle body into the receiving portion of the base body, applying a setting force to the buckle body in a first direction relative to the base body and forcing the buckle body engagement element to engage the first directional retaining portion of the base body and retaining the buckle body in the base body. The setting force applied to the buckle body overcomes the flex of the engaging element and allows the engaging element to pass through the receiving portion profile of the cavity. The setting force is not enough to allow the engaging element to pass through the first directional retaining portion profile of the cavity. The buckle body is also retained in the cavity of the base body in a second direction by the receiving portion profile. When a non-removing force is applied to the base body, the receiving portion profile retains the buckle body in the cavity. The buckle body may also be retained in the cavity by an interior surface defined by a cavity bottom wall, a cavity top wall and a cavity side wall. The interior surface engages the buckle body and retains the buckle body in a first and second dimension. Through the interoperation of elements, the buckle body is retained in the base body in two dimensions through the interior surface walls and the buckle body is retained in the third dimension by the constraining profiles of the first directional retaining portion and the receiving portion of the base body.
As shown in the example embodiment of
For the base body embodiments illustrated in
In embodiment of the buckle body similar to those illustrated in
In embodiments similar to those illustrated in
In embodiments, the setting force can be applied without needing complex manipulation through methods such as putting a force on a coupled strap or pulling on the buckle body or having to flex the engaging element with fingers. When using Silicone Rubber, the tension of the strap may pull the buckle body into the cavity of the buckle body.
Operationally, embodiments of the buckle assembly can also include removing the buckle body from the base body by applying a removal force to the buckle body relative to the base body and forcing the buckle body through the receiving portion and out of the cavity of the base body. The removal force is enough to flex the engaging element of the buckle body inward so that it passes through the second directional retainer and the receiving portion profile of the base body. In some embodiments, the removal force removes the engaging element of the buckle body from the restrainment of the second directional retainer allowing the buckle body to be removed from the cavity.
In some embodiments, the buckle assembly may be used with an orthotic brace to couple or otherwise connect brace elements to each other such as coupling a strap to a brace. Suitable braces which may be utilized with embodiments of the disclosed brace assembly include, but are not limited to those braces described in co-pending U.S. patent application Ser. No. 13/541,796 filed Jul. 5, 2012, co-pending U.S. patent application Ser. No. 13/188,506 filed Jul. 22, 2011 now U.S. Pub. No. 20110275970 and co-pending U.S. patent application Ser. No. 12/993,258 filed Nov. 18, 2010 now U.S. Pub. No 20110071451, the entire contents of all are herein incorporated by reference in their entirety. For some embodiments used with an orthotic brace, the configuration and operation of the buckle assembly benefits users in that the buckle body and base body may be coupled with minimal manual dexterity. The buckle body may be received into the base body by overlapping the buckle body over the base body and slipping the engaging elements into the receiving portion of the base body. Once received, the coupling is secure. To remove the buckle body, it may be disengaged from the base body by providing a removing force on the pusher portion and pushing the buckle body out of the base body. The removal force may also be applied without complex hand manipulation. For example, the removal force can be applied by a thumb or other finger or it may be provided by forcing other element of the buckle body or strap. Additionally, in embodiments that include appropriate strap couplers and straps, adjustment of the orthotic brace can be done with minimal adjustments. For example and not for limitation, when a strap and strap coupler as those illustrated in
