Abstract
Description
- The present invention relates to an adjustable buckle for mounting on relatively movable portion of a sport boot that enables the wearer to readily adjust the sports boot during athletic endeavors.
- Sports boots, for example, ski boots and ice hockey boots formed of plastic materials, are closed by buckles. Ordinarily two portions of the boot, for example, overlapping flaps, are provided with a catch on one portion and a latch on the other. Several buckles are normally used to close the boot.
- The fit of sports boots must be accurately controlled by the wearer. Often the boot must be tightly fitted and thus under a high tension for one type of activity, while more loosely fitted and under a lower tension for another type. Moreover the foot tends to change in size slightly during the day. Thus it is essential for the buckles to be readily adjustable under all conditions, for example, on a mountain while skiing to permit the wearer the option of tightening or loosening the boot a precise amount at any time.
- A boot buckle that has been widely and satisfactorily used and has fulfilled many of the needs of sports boot wearers, is shown in U.S.Patent N8 4.051.611, issued in the name of Edward L.Chalmers, one of the present inventors, and assigned to the assignee of the present invention. However, micro-adjustment of the patented buckle requires rotation of a wireform and its holder on a threaded shaft. It would be advantageous to provide a simpler and more rapid adjustment of the buckle and yet retain the required precision of boot tensioning.
- The present invention provides an adjustable buckle for sports boots which can be easily and quickly adjusted with precision on or off a ski mountain, for example. This is achieved by the features combined in the characterizing part of
claim 1. - In a typical embodiment of the invention, the buckle latch includes a shaft attached to the manually actuatable mechanism for moving the shaft relative to the catch. A hooking device, for example, a wireform, extends from a carrier which is coupled by ratchet means to the shaft. In this embodiment the shaft is provided with suitable teeth and the carrier includes pawls cooperating with the teeth. Manually operated handles on the pawls facilitate adjustment of the hook and carrier relative to the shaft, thereby permitting fine or micro-adjustment of the buckle.
- The invention will be better understood when the following description is read in connection with the accompanying drawings.
- Figure 1 illustrates a ski boot closed by four of the inventive adjustable boot buckles;
- Figure 2 is a view in perspective of one of the adjustable boot buckles shown in Figure 1;
- Figure 3 is a partial bottom view, greatly enlarged and partially broken away, of the adjustable boot buckle;
- Figure 4 is a bottom view of the inventive boot buckle similar to Figure 3, but showing a modified ratchet arrangement;
- Figure 5 is a side view of a modified adjustable boot buckle in accordance with the present invention;
- Figure 6 is a view in cross section taken on the line 6-6 of Figure 5 looking in the direction of the arrows; and
- Figure 7 is a top view of the boot buckle shown in Figure 5.
- Referring to the invention in greater detail, with particular reference to Figure 1, a
sports boot 10, here shown as a ski boot, normally formed of a suitable plastic, includes a boot lower 11, a boot upper orcuff 12, secured byrivets 13 to the lower 11. Movable portions orflaps buckles 18 are provided to close theski boot 10. Each of thebuckles 18 includes acatch 19 formed withteeth 19a for macro-adjustments of the buckle, and alatch 20, on the overlapping boot flaps. - Referring to the
buckle 18 in greater detail, with particular reference to Figure 2, a hookingwireform 21 is suitably attached as shown to acarrier 22. Ashaft 23 coupled by ratchet means, described hereinafter, to thecarrier 22, is pivoted bypin 24 tolatch handle 25. Alatch base 26, fastened by rivets or the like to the boot, pivotally supports thehandle 25 viapin 27. Aninternal spring 27a maintains the latch closed against the boot and aids in positioning the wireform in thecatch 19. - The adjustable feature of the boot buckle is shown in greater detail in Figure 3. The
rectangular shaft 23 is formed withteeth 28 cut inchannels 29 on opposite sides of the shaft.Pawls 30 provided withteeth 31 formed to mesh with theteeth 28, are pivoted onpins 32 in thecarrier 22.Handles 33, adapted to be manually operated by the boot wearer, pivot the pawls to disengage theteeth 31 from theteeth 28, thereby permitting the carrier to be moved with respect to theshaft 23. Springs 34 bias thepawls 30 into engagement with theshaft 23. Slot 35 in a web 36 of thecarrier 22 guides movement of theshaft 23 in the carrier. Note that with this arrangement, thecarrier 22 andwireform 21 can be moved somewhat off center with respect to theshaft 23, thereby permitting better seating of thewireform 21 in thecatch 19 when the latch and catch are not aligned with the boot closed. - In operation of the inventive buckle, one of the
teeth 19a is selected for macro-adjustment of the boot tension. The buckle is then released byhandle 25, and thepawls 33 are operated to slide thecarrier 22 along theshaft 23 to provide for micro-adjustment of the boot tension. - A modified form of the inventive adjustment feature is shown in Figure 4 in which elements corresponding to those in Figure 3 are designated by primed numerals. In this embodiment, a rectangular shaft 23' is formed with angled teeth 28' in
channels 29'. Pawls 30' include teeth 31' mating with the teeth 28'. With this arrangement, when a boot wearer wishes to tighten the boot slightly, as often occurs after a few ski runs, the wearer need merely push the carrier 20' along the shaft 23' in the direction indicated by the arrow 37. The pawls 30' will ratchet down the shaft 23' and hold the carrier 20' at a desired location. To loosen the boot adjustment, the handles 33' are manually operated and the carrier 20' moved upwardly along the shaft 23'. - Still a further embodiment of the inventive adjustable fastener is shown in Figures 5,6 and 7. It is desirable to provide boot buckles conforming as closely as possible to the boot surface for both functional and aesthetic reasons. To this end, the buckle shown in Figures 5-7 includes a number of parts similar to and identified by the same reference numerals as the buckle in
- Figure 2, but also includes a
curved shaft 38 provided withteeth 39 in grooves 40 (Fig.6). An enlargedportion 38a extends into thehandle 25. Thegrooves 40 are configured to provide convex surfaces 41 andangled surfaces 42 for cooperating withteeth 43 on thepawls 44. The pawls are mounted similarly to thepawls 33 shown in detail in Fig.3, and cooperate with theteeth 39. Acarrier 45 includes upper andlower portions upper portion 46 andlower portion 47 is formed to provideenlargments shaft 38. These provide interior surfaces 46b and 47b cooperating withsurfaces 38a on theshaft 38 to permit limited rotational or twisting movement of the shaft with respect to the carrier. Depressed surfaces 46c and 47c limit the amount of rotation and movement. Note that thepawl teeth 43 are smaller than thechannels 40 to permit such rotational movement. This arrangement also permits a limited amount of movement of the carrier to and from with respect to the axis of theshaft 38. Other desired tooth arrangements may be used for the ratchet device of the fastener, depending upon the particular alignment requirements of the latches and catches on the flaps of the boots. - A
curved hooking device 48, contoured to the boot surface, includesarms 49 pivoted bypin 50 to thecarrier 45. Ahook 51 on the end of thehooking device 48 is selectively engageable withteeth 19a of thelatch 19. - The adjustable fastener of Figures 5-7 provides macro-adjustments through selection of the
teeth 19a engaged by thehooking device 48, and micro-adjustment by manual operation of thepawls 44 to permit movement of the carrier along theshaft 38. - It will be understood that the above described embodiments of the invention are merely exemplary and that persons skilled in the art may make variations and modifications without departing from the spirit and scope of the invention. All such modifications and variations are intended to be within the scope of the invention as defined in the appended claims.
