Definitions
- the present invention relates to the field of buckling closures. More particularly, the present invention relates to a buckle device for providing enhanced opening and closing. More particular yet, the present invention involves an easily adjusted tension mechanism within an athletic-boot buckle, where tension is adjustable from any buckle position including a fully latched position.
- ski-boots In the field of downhill-skiing, speed is an intrinsic factor, and loose ski- boots can be fatal. Thus, it has long been common within this field to use ski-boots that fit tightly. Typically, such ski-boots have been provided with clamp-like buckles that are able to firmly close a ski-boot. Although this type of prior-art buckle tends to provide a tighter ski-boot fit, it is often very difficult to move into and out of position. The difficulty is even more pronounced for individuals who have limited manual dexterity or hand-strength. Typically, children and those with arthritic hands often are unable to open or close such prior-art buckles without assistance. Further, even individuals with otherwise-normal hand strength and dexterity find that cold weather conditions and the presence of gloves renders such prior-art buckles unmanageable.
- the prior-art mechanisms fail to provide any fastening device that enables engagement and disengagement of a buckle by individuals with limited dexterity. Also, the prior-art mechanisms fail to provide any fastening device that can be adjusted while the buckle is engaged and without being limited to the fixed clamping-positions. Therefore, what is needed is a buckle device that provides secure and tight closure.
- buckle device that provides tension adjustment that assures that ski-boots are not loose or otherwise ill-fitting due to buckle tension. Further, what is needed is such a buckle device that provides tension adjustability while the clasp is engaged and without regard to the fixed clamping-positions of conventional buckles.
- Another object of the present invention is to provide such a buckle device that is able to tightly close in a securely locked fashion.
- Yet another object of the present invention is to provide such a buckle device that substantially eliminates looseness of a ski-boot through enhanced buckle tensioning.
- Still another object of the present invention is to provide such a buckle device that allows an individual having limited hand strength and dexterity to quickly and easily engage and disengage a ski-boot buckle. It is also an object of the present invention to provide such a buckle device that can be relieved of tension yet able to be maintained in a position slightly less than full disengagement so as to prevent buckle damage or loss.
- the buckle device of the present invention includes multiple hooks on a hook section, a loop section, and a pivotable clasp section.
- An adjustable section is located between the loop section and the pivotable clasp section.
- the hook portion is permanently affixed to one half of a ski-boot opening, while the base portion of the clasp section is permanently affixed to the other half of the ski-boot opening.
- the adjustable section permits tension adjustments up to full buckle engagement. Such adjustments are preferably made after the clasp is closed so as to draw the ski-boot flaps. However, it should be noted that it is possible that such adjustments are made before closing the clasp.
- the adjustable section is optionally provided with a knob, a ratchet, or a swiveling key as its actuation means, each of these actuation means being operably connected to a gearing mechanism.
- the gearing mechanism may be any one of a worm-gear, rack-and-pinion-gear, planetary-gear, or some other type of gearing that exhibits a suitable gearing ratio.
- a continuous ratcheting unit may also be employed.
- a gearing mechanism that provides both ratcheting and a locking-in of the setting may also be used.
- a suitable gearing ratio for purposes of the invention would enable high torque gear output with minimal input by a user.
- the gearing mechanism provides micro adjustment between the hook and loop sections and the clasp section through manual rotation of the actuation means.
- an optional cover may be provided for movable placement over the hook and loop sections.
- the present invention's key aspect is that it provides tension adjustment "on-the-fly" whenever the need arises and wherever the user happens to be located. Even after initial buckle engagement where each buckle device is fully clamped into place, a user can quickly and easily fine-tune the tension of any number of buckles. In this way, loosening of a user's foot within a boot during an athletic activity can be corrected immediately by the user without disengaging or undoing the buckle in any way. Thus, at any moment during the athletic activity, a user can manipulate the overall tightness of the boot to any desired level.
- the actuation means is large enough and strong enough so that nearly any user is able to adjust the tension of the buckle device.
- the invention may be utilized in a variety of ways including, but not limited to, placement on down-hill ski-boots, roller-skates, in-line-skates, and ice-skates. Again, the present invention may be used even by persons using bulky gloves without compromising its usefulness. It is to be understood that other objects and advantages of the present invention will be made apparent by the following description of the drawings according to the present invention. While a preferred embodiment is disclosed, this is not intended to be limiting. Rather, the general principles set forth herein are considered to be merely illustrative of the scope of the present invention and it is to be further understood that numerous changes may be made without straying from the scope of the present invention.
- FIGURE 1 is a top-view of a buckle device in accordance with a first preferred embodiment of the present invention showing a knob-type actuation means.
- FIGURES 2 is a cut-away side-view of the buckle device as shown in FIGURE !
- FIGURES 3 is a top-perspective view of a buckle device in accordance with an optional protective cover.
- FIGURE 4 is a cut-away side-perspective view of the buckle device as shown in FIGURE 3.
- FIGURE 5 is a cut-away partial side-view of a buckle device in accordance with a second preferred embodiment that includes a swivel-type actuation means.
- FIGURE 6 is a cut-away partial side-view of a buckle device in accordance with a third preferred embodiment that includes a ratchet-type of actuation means.
- FIGURE 7 is a ski-boot shown in its entirety utilizing the first preferred embodiment as detailed in FIGURES 3-4.
- a buckle device 10 is shown according to a first preferred embodiment of the present invention.
- the buckle device 10 is shown connecting to two opposing portions of a footwear surface, the portions shown as two flaps 28, 30. Although these flaps 28, 30 could be surface parts of any type of athletic equipment, they are preferably related to foot-gear and, more specifically, ski- boots.
- the buckle device 10 has key elements that include a clasp 26, an adjustable section 23, a loop 16, and a hook section 12.
- the clasp 26 is pivotably connected to flap 30 by means of a first pin 26a.
- the clasp 26 is also pivotably connected to an arm 36 of the adjustable section 23 by means of a second pin 26b.
- the arm 36 of the adjustable section 23 is preferably formed integrally with a main body 22 of the adjustable section 23.
- the adjustable section includes an actuation means shown in the form of a knob 24.
- the knob 24 is preferably a relatively large and rounded shape with a relatively flat vertical section.
- the knob 24 being shaped similar to that of a common stove knob.
- any suitable shape can be used that would provide the preferred ergonomic shape and characteristic of being easily manipulated by a user's hand with or without hindrances. Such hindrances could be clothing articles such as ski-gloves or mittens with or without additional hindrances including physical handicaps such as arthritis or small, weak hands.
- the knob 24 is preferably detachable so that encumbrances on the user are minimized.
- the knob 24 have a threaded female receiving end for accepting a male threaded bolt that is substantially permanently affixed to gearing 20 of the buckle. In that way, snow build-up in the device is eliminated.
- gearing 18, 20 is shown coupled to the knob 24. More specifically, rotary gear 20 is directly coupled to the knob 24 so that rotation of the knob 24 results in rotation of rotary gear 20. This rotary motion is then transferable to worm gear 18 such that a linear motion is created.
- Connected to the worm gear 18 is a loop 16 that is designed to securely be seated on any one of hooks 14.
- Multiple hooks 14 exist on the hook section 12.
- the hook section 12 is itself firmly affixed in any conventional manner -e.g., adhesive, screws, tacks, etc.— to the other flap 28 of the two flaps 28, 30.
- the two flaps 28 and 30 are connected by way of the buckle device 10 and adjustment between the flaps 28, 30 is accomplished by rotation of the knob 24 to activate the adjustment section 23.
- Retrofitting conventional clamping ski-boot buckles is also a preferable use of the invention where only the loop 16 and adjustment section 23 are provided for attachment to a pre-existing clamp 26 and hook section 12.
- the buckle device 10 functions by having a user manually place loop 16 over one of the hooks 14 and then pivot the clasp 26 downwards to result in what is shown in FIGURE 1 and 2.
- the knob 24 is rotated manually by the user, thereby actuating the gearing 18, 20 and drawing the loop 16 towards the clasp 26.
- Loosening of the buckle device 10 is done by first rotating the knob 24 and hence related gearing 18, 20 in the opposite direction so that tension on the clasp 26 is significantly reduced. This allows the clasp 26 to then be pivoted upwards with minimal effort on the part of the user.
- the loop 16 may then be removed from the hook 14 entirely.
- FIGURES 3 and 4 An optional element of the present invention is shown in FIGURES 3 and 4 which differ from the first preferred embodiment only in that a cover means — shown in the form of a protective hook-cover 14a - is included for shielding the hook section 12 and holding down the loop 16.
- the additional hook-cover 14a is easily attached to the buckling device 10 at one end of the hook section 12.
- the hook-cover 14a is held in place preferably by means of a screw 13.
- any other suitable method of affixing the hook-cover 14a can be used including adhesive, plastic-rivet, stitching, and the like.
- the hook-cover 14a normally rests down against the hooks 14 atop the hook section 12.
- the hook-cover 14a is preferably made of a plastic that is flexible enough so that it may be pulled up and away from the hooks 14 when the loop 16 requires movement on and off any given hook 14.
- a pivoting hinge (not shown) may also be used in lieu of the screw 13.
- Such a pivoting hinge may be an axle separate from the hook-cover 14a or nubs that are formed integrally with the hook- cover 14a.
- the hook-cover 14a serves to protect snow from accumulating in the hook section 12 (when the invention is utilized in ski-boots) and serves to retain the loop 16 in position atop the hook section 12 regardless of the tension level of the adjustment section 23.
- FIGURES 5 and 6 Second and third preferred embodiments are shown in FIGURES 5 and 6, respectively. These embodiments differ from the first preferred embodiment only in that the actuation means in the previous form of knob 24 has been changed to include a swivel-key 24a in FIGURE 5 and a ratchet 24b in FIGURE 6. All other structural elements remain unchanged and the embodiments in FIGURES 5 and 6 may further optionally include the protective hook-cover 14a as shown in FIGURES 3 and 4.
- the swivel-key 24a operates rotationally similarly to the embodiment including the knob 24 except that the swivel-key 24a is further able to pivot about a swivel-key-axis 50. This allows the swivel-key 24a to pivot downwards into a low-profile position when not being used. Such an arrangement enables a larger sized actuation means to be utilized.
- a ratchet 24b as shown in FIGURE 6 is provided to increase the torque available to the user in turning the associated gearing 18, 20.
- gearing 18, 20 may include planetary gearing, ratcheting gearing, or any other suitable gearing that magnifies the users adjustment capabilities.
- alternative ratcheting gearing will include reversible and releasable aspects commonly understood with respect to mechanical ratchet wrenches.
- FIGURE 7 multiple buckle devices 10 are shown in the preferred manner of use for the present invention - i.e., situated upon a ski-boot 70.
- the particular embodiment shown is that of FIGURES 3 and 4.
- Protective covers 14a are shown in place above the hook sections 12. This partially exposes some of each loop 16, yet hides most of each from view.
- the flaps 28 and 30 are more clearly seen by way of FIGURE 7 as edges of the outer-covering of the ski-boot 70.
