The present invention relates to belt buckles, and more particularly to belt buckles that releaseably connect to a belt strap with a separate clasp mechanism.
Buckles have long been used to fasten two ends of a belt strap to one another. Two common types of buckles include the frame-style buckle and the plate-style buckle wherein the buckle is permanently connected to one end of the belt and removably fastens with the other end of the belt. In either these buckle type or the various other buckle types available in the prior art, the general principle is the same wherein the buckle is affixed to one end of the belt strap, the belt strap is secured around the waist of a wearer through multiple belt loops on the garment of the wearer, and the free distal end of the belt strap connects with the prong of the buckle. Therefore, the entire belt must be removed in order to remove the buckle, which can be an inconvenience to the wearer. Accordingly, it is desirable to provide a belt and buckle that does not necessarily need to be completely removed in situations where a person is going through a metal detector at a security checkpoint. Accordingly, there is a desire in the art to provide a belt buckle that can be easily removed from the belt without the wearer necessarily removing the belt strap from around their waist.
In a traditional frame-and-prong buckle, the frame connects to the proximal end of the belt strap with a prong attaching to one end of the frame and extending away from the wearer through a hole in the belt strap, where it anchors against the opposite side of the frame. In comparison, traditional plate-style buckles include a belt plate that is a substantially planar surface, such as with the Snap-On buckle described by Casanova® and shown in
Along with multiple buckle types in the prior art that fasten in various ways, there are multiple known ways to connect the buckles to belt straps. Some of the most common mechanisms for attaching a buckle to the end of a belt strap include providing a loop in the proximal end of the belt, screws, a chape, and snaps. When a loop is provided, the proximal end of the belt is looped through a portion of the buckle and is then sewn closed. Similarly, the loop can be secured with snaps or other fasteners rather than being permanently sewn. However, the buckle may not be detached without damaging the belt or may include a release mechanism on the proximal end of the strap, such as in the Switch Buckle™ belt shown in
Other variations of buckles that permanently attach to the proximal end of the belt strap include a screw attachment where the buckle has a chape that is attached to the proximal end of the belt. The chape has holes where screws pass through and pierce the belt. Of course, the screws may be removed to disconnect the buckle from the belt but this process requires a screwdriver with a very small head and repeated detachment and reattachment will cause permanent damage to the belt. Similarly, other buckles may have a chape that attaches to the proximal end of the belt via a toothed mechanism. When closed, the teeth will pierce the belt and opening the teeth mechanism to remove the buckle requires a small pry-bar and repeated detachment and reattachment will cause permanent damage to the belt.
In comparison, buckles exist that releaseably attach to the proximal end of the belt and which can be quickly detached without additional tools. For example and as mentioned above, snaps can be used to attach the buckle to the proximal end of the belt where the proximal end of the belt is looped through the buckle, and then closed. The attachment mechanism is therefore attached to the belt, not the buckle. Further, these snaps are generally metal and a wearer cannot wear them while going through a security area.
Other examples of removable belt buckles include US Pat. No. 489,656 and U.S. Pat. No. 7,520,031 which describe buckles with a post that engage holes at both ends of the strap. However, these buckles necessarily require a hole at both ends of the belt strap and cannot readily be attached to the proximal end of the belt for an extended period of time. Another example of a removable belt includes the Flybelt™ which particularly requires a separate attachment mechanism on the proximal end of the belt that engages with the buckle, as shown in
Accordingly, the removable buckles in the prior art fail to provide a simple mechanism within the buckle itself that allows for a quick and easy removal. Accordingly, there remains a need in the art to provide an improved buckle that provides a clasp to connect the proximal end of the belt to the buckle.
The invention described herein is a removable belt buckle that can quickly be disconnected from a belt, preferably made of leather, and subsequently reconnected without necessarily removing the belt from the waist of the wearer. It is a particular aspect of the invention to allow for the buckle to quickly be removed prior to a wearer walking through a metal detector, for example at an airport or courthouse, without the wearer having to necessarily remove their entire belt. Accordingly, the belt strap preferably has no metal pieces or fasteners wherein the clasping mechanism, which allows for the quick removal of the buckle, is solely housed within the buckle rather than on the proximal end of the belt strap.
The buckle is generally made up of a frame, a clasp operatively connecting the frame to the belt and a restriction bar. A prong extends outwardly from the back face of the frame to engage a hole in the distal end of the belt strap and the restriction bar is situated on the opposite end of the back face of the frame from the prong. The clasp has a pair of fingers at one end and a corresponding pair of arms that extend to a joint at the opposite end of the clasp. When the buckle is connected to the belt, the fingers are positioned within a loop in the proximal end of the belt strap and the joint on the opposite end of the clasp from the fingers engages the bottom portion of the prong or a separate catch proximate thereto. Accordingly, the joint engages the catch that is either integrated with the prong of the buckle or separated from the prong and positioned between the prong and the restriction bar. To fasten the belt, the end of the prong is inserted into the hole on the free end of the belt and the buckle thereby connects the ends of the belt together.
In operation, the restriction bar restricts the movement of the arms and fingers of the clasp. The clasp arms pivot at the joint between a reduced angle when the clasp and restriction bar are actuated and an expanded angle when the clasp and restriction bar are unactuated. The joint continuously biases the pair of arms towards the expanded angle but when the clasp and restriction bar are in the actuated configuration, the distal ends of the arms abut the standoffs of the restriction bar and the arms are thereby prevented from expanding beyond the reduced angle. Conversely, when the clasp and restriction bar are in the unactuated configuration, clearance is provided between the distal ends of the arms of the clasp and the restriction bar and the joint biases the arms apart. Subsequently, the space between the fingers widens and the buckle can be disengaged from the loop at the end of the belt where the fingers can slide out of the loop.
In one buckle embodiment, the restriction bar is fixedly attached to the back face of the frame by the standoffs and the clasp slides through the opening between the frame and the restriction bar. When engaged, the joint is proximate to the opposite end of the frame from the restriction bar and the ends of the arms opposite from the joint abut the standoffs. Conversely, when unactuated, the joint is moved towards the restriction bar and the distal ends of the arms disengage the standoffs, allowing the joint to bias the arms of the clasp towards the expanded angle and subsequently move the fingers away from one another.
In an alternative buckle embodiment, the restriction bar slidingly connects to the back face of the frame within a pair of longitudinal recesses. When actuated with the clasp, the restriction bar is slid towards the end of the frame on the opposite end as the prong and the standoffs engage the distal ends of the arms, biasing the arms to the reduced angle and moving the fingers together. Conversely, when unactuated, the restriction bar is slid towards the prong where the distal end of the arms disengage the restriction bar and the arms can expand.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The present invention will become more fully understood from the detailed description and the accompanying drawings, wherein:
The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
The removable belt buckle consists of a plate buckle that is used to connect the opposite ends of a belt strap while providing a clasp mechanism to quickly disconnect the buckle from the belt without the wearer necessarily removing the belt. As with belts in the prior art, the belt described herein has a free distal end with one or more holes for fastening the belt with one end of the buckle and a proximal end with a loop that removably attaches to the other end of the buckle. In traditional belt and buckle combinations, the proximal end of the belt is permanently attached to the buckle. To secure the belt around the waist of a wearer, the distal free end has a series of holes that secure within a prong on the back face of the frame of the buckle, as with other belts and buckles in the prior art. However, the innovative buckle described herein has a clasp mechanism that removably connects to the buckle to the loop in the proximal end of the belt. The clasp allows the proximal end of the belt to be connected and disconnected to the buckle in a repeated manner that does not bring harm to the loop in the end of the belt nor necessarily requires the belt strap to be removed from the waist of the wearer.
To provide a simpler belt buckle, the attachment mechanism is contained within the buckle with a clasp that engages a loop in the proximal end of the belt. Accordingly, the proximal end of the belt does not have any mechanical attachment mechanism and preferably has a sewn loop 108, such as shown in
The belt used with the removable buckle described herein is generally a belt strap with a free distal end and a proximal end that connects with the buckle. As with known belts, the strap is designed to encircle the waist of the wearer and pass through one or more belt loops in order to hold up the wearer's trousers or shorts. As particularly shown in
The removable belt buckle 10 particularly includes a frame 12, a restriction bar 14, a clasp 16 and prong 18 that collectively operate to connect the buckle to both the proximal end 102a and distal end 102b of a belt 100. The frame includes side edges 32 and ends 34 with a front face 30b that faces away from the wearer and back face 30a that faces towards the waist of the wearer. The frame itself preferably has a curvature, as depicted in
As with other buckles in the prior art, the buckle described herein is designed to temporarily fasten two ends of a belt strap together and support the garment of a wearer. The buckle includes a traditional prong protruding a prong length 36 from the back face of the frame which is illustrated in
The inventive buckle described herein further includes a clasp which releaseably connects to a loop 106 in the proximal end of the belt on the opposite end of the buckle frame from the prong, such as shown in
The clasp includes a pair of arms 46 extending from a joint 44 connecting the proximal end of the respective arms 50a to a pair of fingers 48 at the distal end of the arms 50b. As illustrated in
To attach the clasp to the buckle, a restriction bar laterally extends between the edges of the frame and provides an opening 42 adjacent to the back face of the frame. In operation, the clasp and restriction bar move relative to one another between an actuated configuration 22 and an unactuated configuration 24 with the angle between the pair of arms reducing as the clasp and restriction bar move into the actuated configuration. In the preferred embodiment, the clasp slides through the opening into the actuated configuration but other embodiments may include a fixed clasp wherein the restriction bar slides along the back face of the frame, as further described herein. The restriction bar includes a center section 40 between a pair of standoffs 38 that connect to the back face of the frame. The proximate ends 64a of the standoffs are respectively attached near opposite side edges 32a & 32b of the frame and extend a standoff length 52 to their respective distal ends 64b that are attached to opposite ends of the center section. Thus, the center section is spaced from the back face of the frame by the length of the standoffs and the opening is formed between the center section of the restriction bar and the back face of the frame.
In the preferred method of operation shown in
To engage and disengage the clasp from the proximal end of the belt, the pair of arms pivot between an expanded angle (α) and a reduced angle (β) (α>β) wherein the joint biases the arms apart and causes the distance 86ba between the fingers at the end of each arm to widen when the clasp is in the unactuated configuration and the standoffs are not biasing the clasp towards the reduced angle. Conversely, as the angle between the arms reduces, the distance 86a between the pair of fingers also reduces where the restriction bar engages the distal ends of the pair of arms and biases the arms towards the reduced angle. As illustrated in
When the clasp and restriction bar are in the actuated configuration, the distal ends of the arms of the clasp engage the respective standoffs and the restriction bar biases the arms together towards the reduced angle, as shown in
As noted above, the standoffs of the restriction bar engage the distal ends of the arms in the actuated configuration and are separated from the distal end of the arms as the joint gets closer to the restriction bar in the unactuated configuration. Thus, the standoffs bias the arms of the clasp towards the reduced angle when the joint is positioned proximate to the prong and the fingers are proximate to the opening. In another aspect of the buckle described herein, the standoffs have a length that is less than the length of the prong so that the prong protrudes past the restriction bar, as shown in
In another aspect of the buckle described herein, the clasp is prevented from sliding through the opening and disengaging the restriction bar where the joint locks with one of the prong or a catch 20 in a locked orientation 26 and disengages the prong or catch in an unlocked orientation 28. Regardless of whether a catch is provided or if the joint simply engages a portion of the prong as explained below, at least one of the clasp and restriction bar move relative to one another between the actuated and unactuated configuration. Similarly, the clasp is prevented from moving between the actuated configuration and the unactuated configuration when the clasp is in the locked orientation but can freely move between the actuated configuration and the unactuated configuration when the clasp is unlocked.
In the preferred embodiment shown in
In operation the joint of the clasp engages the catch in the locked orientation as shown in
In the alternative embodiment shown in
When the restriction bar is slid towards the locked end into the actuated configuration, such as shown in
In another alternative embodiment shown in
As shown in
In another aspect of the invention, the prong may include a top portion 72a that is intended to engage the hole in the distal end of the belt and a bottom portion 72b that engages the joint in the locked orientation. As shown in
In addition to various shapes used in the top portion of the prong, a cutout section 74 may be used in the bottom portion of the prong as shown in
Additionally, it is an aspect of the preferred embodiment to have a prong length that is greater than the height of the restriction bar. Accordingly, the prong can accommodate the joint of the clasp and still securely hold the distal end of the belt to the buckle. Alternatively, it will be appreciated that the length of the prong may be shorter than the height of the restriction bar, such as when the joint engages a separate catch as described herein. However, when a catch is used, such as in the preferred embodiment, the catch has a length that is less than
The embodiments were chosen and described to best explain the principles of the invention and its practical application to persons who are skilled in the art. As various modifications could be made to the exemplary embodiments, as described above with reference to the corresponding illustrations, without departing from the scope of the invention, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto and their equivalents.
