There is a locking mechanism formed by a base plate having a locking device on an underside and a guide for slidably connecting the locking mechanism to the strip. The teeth and the locking device are configured so that the locking device can be moved forward along the strip using only a small amount of force, and can then be moved rearward using a larger amount of force.
Description
- 1. Field of the Invention
- This invention relates to an adjustment system for increasing and decreasing the circumference of an article, such as a sleeve cuff or footwear. In particular the invention relates to an adjustment system using a ratcheting device to adjust the width of the article.
- 2. The Prior Art
- In some articles of apparel, such as jacket sleeve cuffs and pant cuffs in athletic clothing, the cuff width needs to be adjusted to be more secure around the wrist or ankle of the user. Traditionally, this adjustment was accomplished via a strap that could be tightened around the cuff, either with a buckle or a hook-and-loop type closure, such as Velcro.®
- The disadvantage to using a buckle is that the buckle is very cumbersome to adjust with only one hand, which is necessary in the case of a sleeve cuff. The disadvantage to using the hook and loop type closure is that the rough surfaces on the closure parts attract a significant amount of debris, which can be unsightly and decrease the adhesiveness of the parts.
- It is therefore an object of the invention to provide an adjustment system that is simple to operate with one hand and which remains free of dirt and debris.
- This object is accomplished by an adjustment system comprising an elongated adjustment strip mounted on a cuff parallel to the edge of the cuff. There are a set of generally triangular teeth extending longitudinally along the strip. The teeth are formed as a ratchet system so that each tooth has a forward side facing a forward direction and a rearward side facing a rearward direction. The length of each of the forward sides is greater than a length of each of the rearward sides so that an angle created between a longitudinal axis of the elongated adjustment strip and the forward side is less than an angle between the longitudinal axis and the rearward side of each tooth.
- There is locking mechanism mounted to a strap that is attached to the cuff. The locking mechanism is formed by a base plate having a locking device extending from an underside thereof and a guide for slidably connecting the locking mechanism to the elongated adjustment strip. The teeth of the strip are configured so that the locking device can be moved along the strip in the forward direction with only a small amount of force required, and can then be moved in the rearward direction using a larger amount of force. This is because the locking device must flex to a lower degree when moved against the forward side of the teeth, having the lower angle, than when moved backwards against the rearward side of the teeth, which have a much steeper angle to overcome.
- The guides can be formed by brackets extending below the bottom surface of the base plate. The brackets engage under the edges of the elongated strip and keep the locking mechanism connected to the elongated strip during the adjustment process. There can be stops mounted at one or both ends of the elongated strip to prevent disengagement of the locking mechanism from the strip.
- In one embodiment, there is a cover plate connected to a top surface of the base plate. A strap or other piece of fabric can be attached to the locking mechanism between the cover plate and the base plate. To keep the strap in position, there can be a set of strap-gripping teeth disposed around the underside of the cover plate and top side of the base plate.
- One advantage of the invention is that the mechanism can be adjusted easily using only one hand. All that is required is to push the locking mechanism along the elongated adjustment strip with the minimum amount of force required for either the forward or rearward direction. To facilitate this adjustment, the top side of the cover plate can be equipped with a series of raised ridges. These ridges prevent fingers from slipping on the cover plate during adjustment, even when the user is wearing gloves.
- In one embodiment, the teeth are located along longitudinal edges of the elongated adjustment device and the locking device comprises two longitudinally extending springs arranged on the base plate so as to engage the teeth when the locking device is moved along the elongated adjustment strip. Here, the strip is attached to the cuff only along the longitudinal axis of the strip, so that the teeth of the strip are not connected to the cuff. This way, the brackets of the locking device can slide under the teeth and keep the locking device in contact with the strip at all times.
- In another embodiment, the teeth are facing upward along an expanse of the elongated adjustment strip, and the locking device comprises a resilient arm that engages the teeth when the locking mechanism is slid along the elongated adjustment strip. In this embodiment, there can be one or multiple rows of teeth along the strip. The brackets on the base plate can engage around edges of the strip to allow the locking mechanism to slide along the strip.

FIG. 17 shows a longitudinal cross sectional view along lines XVII-XVII ofFIG. 15 . - Referring now in detail to the drawings,
FIG. 1 shows a view of the view of the system according to the invention installed on aboot 1. The system comprises anelongated adjustment strip 10 and a locking mechanism generally designated as 20 attached to astrap 2 ofboot 1.Locking mechanism 20 slides alongadjustment strip 10 to tighten or loosenboot 1 as desired. The structure and function of the system is explained below with reference to the remaining Figures. -
FIGS. 2 and 3 show theelongated adjustment strip 10 according to one embodiment of the invention. The strip has a set ofteeth 11 extending along each of the two longitudinal sides ofstrip 10. Acentral portion 12 ofstrip 10 is recessed on the top surface as shown inFIG. 2 and protrudes from the bottom surface as shown inFIG. 3 . This way, thecentral portion 12 can be attached to an article along the bottom surface ofstrip 10 while leavingteeth 11 free. Each one ofteeth 11 has aforward side 13 facing a forward direction and arearward side 14 facing a rearward direction. Eachforward side 13 is longer than eachrearward side 14, so that an angle α between the longitudinal axis L and the forward side is less than an angle β between the longitudinal axis L and the rearward side, as shown inFIG. 11 . This creates a ratcheting type of design with thelocking mechanism 20 as explained in further detail below. - On the end of
strip 10 is astop 18, which prevents further movement of lockingmechanism 20 alongstrip 10 to keep the two components together. - The pieces of locking
mechanism 20 are shown inFIGS. 4-8 .FIGS. 4-6 show thebase plate 21 of lockingmechanism 20.Base plate 21 has a set of guides in the form ofbrackets 22 for receiving edges ofstrip 10 as lockingmechanism 20 is fed alongstrip 10. A locking device in the form ofsprings 23 is disposed between guides 22.Springs 23 engageteeth 11 as lockingmechanism 20 is slid alongstrip 10. - On the top side of
base plate 21 there are a plurality offabric gripping teeth 24, and catches 25 for engaging acover plate 26, which is shown inFIGS. 7 and 8 .Cover plate 26 has a series oflateral ridges 28 along its top surface, andapertures 27 for engaging withcatches 25 onbase plate 21 to securecover plate 26 tobase plate 21. The underside ofcover plate 26 has a plurality offabric gripping teeth 29 as shown inFIG. 8 . - As shown in
FIG. 9 , astrap 30 can be attached to lockingmechanism 20 by placingstrap 30 betweencover plate 26 andbase plate 21. Once catches 25 engageapertures 27,fabric gripping teeth grip strap 30 from the bottom and top and preventstrap 30 from releasing from lockingmechanism 20. - The operation of this embodiment of the system is shown in
FIGS. 10-13 . As shown inFIG. 10 ,locking mechanism 20 is attached to strip 10 by slidingbase plate 21 alongstrip 10 so thatteeth 11 slide withinguides 22 and are engaged bysprings 23.Springs 23 are shaped similar toteeth 11 so that they engageteeth 11 and keepteeth 11 in place until a force that exceeds the spring force ofsprings 23 is applied. To movelocking mechanism 20 in a forward direction alongstrip 10, a first amount of force F1 is applied, which causes springs 23 to flex outward and allowbase plate 21 to be slid past one set of teeth until a desired position is reached, in which springs 23 engage a next set ofteeth 11. The lower angle α created byforward side 13 ofteeth 11 means that only a small amount of force F1 needs to be exerted onsprings 23 to movesprings 23 out of engagement withteeth 11, as shown inFIG. 11 . In order to movelocking mechanism 20 in the rearward direction, a greater amount of force F2 is required, so that springs 23 can overcome the greater angle β of the rearward side ofteeth 11. Thus, it is easier to movelocking mechanism 20 in the forward direction than in the rearward direction. The spring force F2 required to movelocking mechanism 20 in the rearward direction should be such that no movement in the rearward direction should occur under normal use and stress, but only when releasing of the system is desired. -
FIGS. 12 and 13 show the system according to the invention in use on acuff 31. Lockingmechanism 20 withcover 26 is attached to strap 30 as shown inFIG. 9 and then lockingdevice 20 is slid alongstrip 10 to tighten or loosencuff 13 the amount desired by the wearer.Lateral ridges 28 oncover plate 26 allowlocking mechanism 20 to be moved forward and backward alongstrip 10 using only a user's finger, even when the user is wearing gloves. Thus, the system according to the invention is ideal for use on athletic apparel such as ski jackets and ski pants, where the wearers are usually wearing gloves and do not want to take them off to adjust their clothing. Pushing forward with the user's finger oncover plate 26slides locking mechanism 20 to the desired level of tightness ofcuff 31. A rearward push with a greater amount of force allowscuff 31 to be loosened again. -
Strip 10 is connected to cuff 31 only alongcentral portion 12 so thatteeth 11 are free to slide within guides 22 (shown inFIGS. 4-10 ) to keep lockingmechanism 20 connected to strip 10. - An alternative embodiment of the system is shown in
FIGS. 14-17 . Here,strip 100 has abase section 101 in which a plurality ofteeth 110 are mounted in two parallel longitudinal rows. Each tooth has a longerforward side 115 and a shorterrearward side 116 to form a ratcheting mechanism in the same way as the embodiment shown inFIGS. 1-13 . Astop 114 is located at one end ofstrip 100 to preventlocking mechanism 200 from sliding off ofstrip 100 when it is mounted thereon.Locking mechanism 200 is mounted to strip 100 by feedingguide portions 113 onstrip 100 throughaperture 211 onguides 210 oflocking mechanism 200. This way,locking mechanism 200 can slide alongstrip 200 without becoming disengaged. - On the bottom of
locking mechanism 200 is aflexible arm 215 which engagesteeth 110 as lockingmechanism 200 is slid alongstrip 100.Locking mechanism 200 can move in a forward direction under a first, low amount of force F1 which causesflexible arm 215 to flex and pass overteeth 11, to tighten a cuff onto which strip 100 is mounted. A greater amount of force F2 is required to flexarm 215 enough to overcome the greater angle created byrearward side 116 of each ofteeth 110 to movelocking mechanism 200 in the rearward direction. - Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
