- a fastening device for a ratchet-type strap including a ratchet-engaging member for releasably engaging a ratchet-type strap to prevent movement of the strap in a first direction; and a tightening member for releasably engaging a ratchet-type strap for moving the strap in a second direction; wherein the engaging member and the tightening member are resiliently biased with respect to each other by a single biasing member which is configured both to bias the engaging member into a position to engage with the strap and to bias the tightening member out of a position of engagement with the strap.
- An advantage of a fastening device is that the tightening member is biased out of engagement with a strap and the engaging member is biased into engagement with the strap by a single biasing member and so the number of components needed to manufacture the device is reduced and thereby manufacturing costs are saved. Unlike in the prior art, where various springs bias different components into their appropriate positions, provision of only a single biasing member can reduce the manufacturing costs as fewer components are required, and can also improve the reliability of the device since the relative positioning of the components is not dependent on the relative biasing of multiple members with various tolerances, each of which needs to be separately adjusted and configured.

- the fastening device 10 is provided on a base 16 that cooperates with the ratchet-type strap 12 as described in more detail below.
- the fastening device 10 in the preferred embodiment, includes only five parts. These are illustrated in Figures 3 and 4 .
- a ratchet-engaging member 30 has a tooth-engaging portion 32 and, at its opposite end, a release lever 34.
- the ratchet-engaging member 30 includes a transverse bore 36 for receiving a pivot 38, the function of which is described below.
- the transverse bore 36 is located between the tooth-engaging portion 32 and the release lever 34.
- a second transverse bore 31 is provided in the ratchet-engaging member 30.

- the ratchet-engaging member 30 also includes an aperture 33, through which a tightening member 35 extends (seen in Figure 3 ).
- the tightening member 35 is fixed to the ratchet-engaging member 30 by means of a pivot 38 and a bar 37 that accordingly extend through transverse bores 36 and 31 in the ratchet-engaging member 30 and through the slots 48 and 49 (seen in Figure 4 ) provided parallel to each other in the tightening member 35.
- the tightening member 35 is thus fixed to the ratchet-engaging member 30 in a manner allowing movement between the tightening member 35 and the ratchet-engaging member 30, for reasons described below.
- the tightening member 35 and the ratchet-engaging member 30 could be said to form an "X" shape, and are able to move with respect to one another by pivoting about pivot 38 and the bar 37 located substantially at the cross-point of the "X".
- the tightening member 35 includes a tightening tooth 39 adjacent a flat surface 40 at one end of the tightening member 35. At the opposite end of the tightening member 35, there is provided a tightening lever 42.
- the tightening member 35 includes a longitudinal bore 44, accommodating the slot 48.
- a helical spring 46 is located within the longitudinal bore 44, for reasons described below.
- the longitudinal bore 44 co-extends with the slot 48, the slot 48 extending only partially along the longitudinal bore 44.
- the helical spring 46 located within the longitudinal bore 44 engages the bar 37 that extends through the slot 48 biasing the bar 37 against the upper part of the slot 48.
- the tightening member 35 includes a bend approximately at the position of the slot 48 and the bar 37.
- the angle of the bend may be approximately 100°.
- the tightening member 35 can thus be said to include two "arms", a first arm forming the tightening lever 42 and a second arm including the tightening tooth 39 at the end thereof.
- the second arm includes the longitudinal bore 44, which, in the illustrated embodiment, can be accessed by an aperture in the first arm.
- the pivot 38 is also used to attach the fastening device 10 to anchor members 20 provided on the base 16 in a moveable manner.
- the device 10 is mounted to the anchoring portions 20 such that a gap for the ratchet-type strap 12 is provided between the ratchet-engaging member 30 and the base 16.
- a gap for the ratchet-type strap 12 is provided between the ratchet-engaging member 30 and the base 16.
- the tooth-engaging portion 32 of the ratchet-engaging member 30 is engaged with the perpendicular surface of a tooth 14 of the ratchet-type strap 12.
- the tooth-engaging portion 32 of the ratchet-engaging member 30 is able to slide over the sloping surface of the teeth 14 of the ratchet-type strap 12 thereby increasing overlap between the base 16 and the ratchet-type strap 12 and providing a tightening function. Relative movement between the ratchet-type strap 12 and the device 10 is thus possible in a tightening direction (i.e. movement of the device 10 and base 16 to the left as shown in Figures 5 and 6 ).
- the tightening member 35 is in a relaxed position. Its flat surface 40 is able to touch the peaks of the teeth 14, but movement of the tightening member 35 across the teeth 14 is not in any way impeded.
- the tightening member 35 is maintained in this position by pressure of the helical spring 46 within its bore 44 against the bar 37. This ensures that the bar 37 is located towards the top of the slot 48.
- the user In order to release the fastening, the user simply presses on the release lever 34. This causes the ratchet-engaging member 30 to pivot about the pivot 38, and cause the tooth-engaging portion 32 to be raised so as to clear the teeth 14. As the user applies pressure to the lever 34, the bar 37 is caused to move within the slot 48 of the tightening member 35 and to compress the helical spring 46. Whilst in this configuration, the ratchet-type 12 strap is able to move freely between the device 10 and the base 16. However, this is only possible as long as the user maintains pressure upon the release lever 34 since release of the release lever 34 causes the helical spring 46 to relax.
- the tightening mechanism is illustrated in Figures 10 and 11 .
- the user can achieve a certain tightness simply by feeding the ratchet-type strap 12 between the base 16 and the fastening device 10 and causing engagement of the tooth-engaging portion 32 of the ratchet-engaging member 30 with a perpendicular wall of a tooth 14.
- the user may require further tightening, which they are unable to achieve in this way.
- the tightening member 35 includes a tightening tooth 39.
- the user lifts the tightening lever 42, which causes the tightening member 35 to pivot about pivot 38 and the bar 37 so that the tightening tooth 39 is able to engage with the perpendicular wall of a tooth 14 of the ratchet-type strap 12.
- the upward movement of the tightening lever 42 causes the bar 37 to move downwards within the slot 48 thereby compressing the helical spring 46.
- the engagement between the tightening tooth 39 and a perpendicular wall of a tooth 14 of the ratchet-type strap 12 causes movement between the device 10 and the ratchet-type strap 12 in a tightening direction (i.e. movement of the device 10 and base 16 towards the left shown in Figures 10 and 11 ).
- the spring 46 provides a pressure against the bar 37 within the slot 48. This biases the device into a ratchet-engaging configuration (as illustrated, in particular, in Figures 5 and 6 ). Release and tightening of the device 10, by contrast, require the user to exert some pressure on either the release lever 34 or the tightening lever 42 respectively.
- This mechanism provides an extremely simple device for providing a secure closure suitable for use on sport-type footwear. In particular, only a single biasing means (the helical spring 46 in the above embodiment) is required and the arrangement between the ratchet-engaging member 30 and the tightening member 35 provides that all of the necessary functionality can be achieved with as few component parts as possible.

Description
- The present invention relates to a fastening device, particularly envisaged for use with sports footwear, such as skates or ski boots.
- Many activities, for example, sports such as skating and skiing, require specialised footwear. In order that the participant can properly control their skates or skis, and also for safety reasons, the user must be able to ensure that their footwear is correctly fitted. Such footwear usually includes a fastening device that enables fine adjustment of the footwear around the user's foot, ankle and/or lower calf. Such fastening devices must be secure, adjustable in small increments, and easily tightenable and releasable.
- Known types of fastening device are disclosed in
US 5,606,779 ,US 5,779,259 ,US 5,887,318 ,US 5,909,850 andUS 7,086,122 . These devices are all very complex requiring many different parts in order to carry out their function. -
US 5,887,318 , for example, discloses a device for clamping a toothed strap comprising two levers and a pawl with a number of linkage components and springs to cause the desired relative movement between the components. - The present invention seeks to provide an improved fastening device.
- According to a first aspect of the present invention there is provided a fastening device for a ratchet-type strap, including a ratchet-engaging member for releasably engaging a ratchet-type strap to prevent movement of the strap in a first direction; and a tightening member for releasably engaging a ratchet-type strap for moving the strap in a second direction; wherein the engaging member and the tightening member are resiliently biased with respect to each other by a single biasing member which is configured both to bias the engaging member into a position to engage with the strap and to bias the tightening member out of a position of engagement with the strap.
- An advantage of a fastening device according to the preferred embodiment is that the tightening member is biased out of engagement with a strap and the engaging member is biased into engagement with the strap by a single biasing member and so the number of components needed to manufacture the device is reduced and thereby manufacturing costs are saved. Unlike in the prior art, where various springs bias different components into their appropriate positions, provision of only a single biasing member can reduce the manufacturing costs as fewer components are required, and can also improve the reliability of the device since the relative positioning of the components is not dependent on the relative biasing of multiple members with various tolerances, each of which needs to be separately adjusted and configured.
- In one embodiment, a coupling member, preferably a bar, attached to one of the engaging member and the tightening member, is held within a guide, preferably a slot, on the other of the engaging member and the tightening member. The bar may provide a pivot point about which the member on which the guide is located is pivotable. In one embodiment, the tightening member and the engaging member share a common pivot. These features can provide for a compact arrangement in which the tightening member and engaging member serve as supports for the pivoting and/or biasing of each other. Therefore, the need for multiple supports, pivot points and springs, as appear in the prior art, is reduced.
- Preferably, the ratchet-engaging member is pivotable. Release of the ratchet-engaging member may be achieved by moving the ratchet-engaging member about a pivot.
- The tightening member may be able to pivot with respect to the ratchet-engaging member. A pivot may be provided on the ratchet-engaging member. The tightening member may be mounted to the pivot by means of a slot through which the pivot extends, the pivot able to move within the slot, the slot being sized to allow movement of the pivot along a single axis. Preferably, the pivot is biased to an end of the slot. The biasing may be provided by a spring, which may be a helical spring. The biasing means may be provided within a channel provided in the tightening member.
- Preferably, the fastening device includes only a single spring.
- According to a second aspect of the present invention there is provided an item of footwear including a fastening device as described above.
- The item of footwear may be, for example, a skate, a ski boot or a snowboarding boot.
- According to a third aspect of the invention, there is provided a fastening device for a ratchet-type strap, including a ratchet-engaging member for releasably engaging a ratchet-type strap to prevent movement of the strap in a first direction; and a tightening member for releasably engaging the ratchet-type strap for moving the strap in a second direction; wherein the tightening member is coupled to the engaging member by a pivot about which one of the tightening member and the engaging member is pivotable with respect to the other.

Figures 10 and11 are perspective cross-sectional views of the fastening device ofFigure 1 in a tightening configuration. -
Figures 1 and 2 illustrate an embodiment of a fastening device in accordance with the present invention. The device 10 is intended for use with a ratchet-type strap 12, which includes a plurality of upwardly-extending teeth 14. The teeth 14 are unidirectional, including a substantially perpendicular surface and a sloping surface. Such ratchet-type straps 12 are well-known in the art. - The fastening device 10 is provided on a
base 16 that cooperates with the ratchet-type strap 12 as described in more detail below. - The fastening device 10, in the preferred embodiment, includes only five parts. These are illustrated in
Figures 3 and4 . A ratchet-engaging member 30 has a tooth-engagingportion 32 and, at its opposite end, a release lever 34. The ratchet-engaging member 30 includes atransverse bore 36 for receiving apivot 38, the function of which is described below. Thetransverse bore 36 is located between the tooth-engaging portion 32 and therelease lever 34. - A second transverse bore 31 is provided in the ratchet-
engaging member 30. The second transverse bore 31 is located between thetransverse bore 36 for thepivot 38 and therelease lever 34. The ratchet-engaging member 30 also includes anaperture 33, through which a tighteningmember 35 extends (seen inFigure 3 ). - The tightening
member 35 is fixed to the ratchet-engagingmember 30 by means of apivot 38 and abar 37 that accordingly extend throughtransverse bores 36 and 31 in the ratchet-engagingmember 30 and through theslots 48 and 49 (seen inFigure 4 ) provided parallel to each other in the tighteningmember 35. - The tightening
member 35 is thus fixed to the ratchet-engagingmember 30 in a manner allowing movement between the tighteningmember 35 and the ratchet-engagingmember 30, for reasons described below. The tighteningmember 35 and the ratchet-engagingmember 30 could be said to form an "X" shape, and are able to move with respect to one another by pivoting aboutpivot 38 and thebar 37 located substantially at the cross-point of the "X". - The tightening
member 35 includes a tighteningtooth 39 adjacent aflat surface 40 at one end of the tighteningmember 35. At the opposite end of the tighteningmember 35, there is provided atightening lever 42. - The tightening
member 35 includes alongitudinal bore 44, accommodating theslot 48. Ahelical spring 46 is located within thelongitudinal bore 44, for reasons described below. Thelongitudinal bore 44 co-extends with theslot 48, theslot 48 extending only partially along thelongitudinal bore 44. Thehelical spring 46 located within thelongitudinal bore 44 engages thebar 37 that extends through theslot 48 biasing thebar 37 against the upper part of theslot 48. - The tightening
member 35 includes a bend approximately at the position of theslot 48 and thebar 37. The angle of the bend may be approximately 100°. The tighteningmember 35 can thus be said to include two "arms", a first arm forming thetightening lever 42 and a second arm including the tighteningtooth 39 at the end thereof. The second arm includes thelongitudinal bore 44, which, in the illustrated embodiment, can be accessed by an aperture in the first arm. - As can be seen in
Figures 1 and 2 , thepivot 38 is also used to attach the fastening device 10 toanchor members 20 provided on thebase 16 in a moveable manner. - In use, the device 10 is mounted to the anchoring
portions 20 such that a gap for the ratchet-type strap 12 is provided between the ratchet-engagingmember 30 and thebase 16. In a closed configuration, the tooth-engagingportion 32 of the ratchet-engagingmember 30 is engaged with the perpendicular surface of a tooth 14 of the ratchet-type strap 12. - In this configuration the tooth-engaging
portion 32 of the ratchet-engagingmember 30 is able to slide over the sloping surface of the teeth 14 of the ratchet-type strap 12 thereby increasing overlap between the base 16 and the ratchet-type strap 12 and providing a tightening function. Relative movement between the ratchet-type strap 12 and the device 10 is thus possible in a tightening direction (i.e. movement of the device 10 andbase 16 to the left as shown inFigures 5 and6 ). However, loosening of the fastening is prevented, because relative movement between the ratchet-type strap 12 and the device 10 in the opposite direction is blocked by abutment of the tooth-engagingportion 32 of the ratchet-engagingmember 30 with the perpendicular surface of a tooth 14. - In this configuration, the tightening
member 35 is in a relaxed position. Itsflat surface 40 is able to touch the peaks of the teeth 14, but movement of the tighteningmember 35 across the teeth 14 is not in any way impeded. The tighteningmember 35 is maintained in this position by pressure of thehelical spring 46 within itsbore 44 against thebar 37. This ensures that thebar 37 is located towards the top of theslot 48. - In order to release the fastening, the user simply presses on the
release lever 34. This causes the ratchet-engagingmember 30 to pivot about thepivot 38, and cause the tooth-engagingportion 32 to be raised so as to clear the teeth 14. As the user applies pressure to thelever 34, thebar 37 is caused to move within theslot 48 of the tighteningmember 35 and to compress thehelical spring 46. Whilst in this configuration, the ratchet-type 12 strap is able to move freely between the device 10 and thebase 16. However, this is only possible as long as the user maintains pressure upon therelease lever 34 since release of therelease lever 34 causes thehelical spring 46 to relax. This, in turn, pushes thebar 37 upwardly within theslot 48, causing pivoting of the ratchet-engagingmember 30 about thepivot 38, and subsequent re-engagement of the tooth-engagingportion 32 with a perpendicular wall of a tooth 14. - As indicated above, it is important for such fastening devices 10 to be adjusted finely and tightly. Therefore a tightening mechanism is provided. The tightening mechanism is illustrated in
Figures 10 and11 . The user can achieve a certain tightness simply by feeding the ratchet-type strap 12 between the base 16 and the fastening device 10 and causing engagement of the tooth-engagingportion 32 of the ratchet-engagingmember 30 with a perpendicular wall of a tooth 14. However, the user may require further tightening, which they are unable to achieve in this way. - The tightening
member 35 includes a tighteningtooth 39. In order to provide additional tightening, the user lifts the tighteninglever 42, which causes the tighteningmember 35 to pivot aboutpivot 38 and thebar 37 so that the tighteningtooth 39 is able to engage with the perpendicular wall of a tooth 14 of the ratchet-type strap 12. At the same time, because the tooth-engagingportion 32 of the ratchet-engagingmember 30 is engaged with the perpendicular wall of the tooth 14, the upward movement of the tighteninglever 42 causes thebar 37 to move downwards within theslot 48 thereby compressing thehelical spring 46. The engagement between the tighteningtooth 39 and a perpendicular wall of a tooth 14 of the ratchet-type strap 12 causes movement between the device 10 and the ratchet-type strap 12 in a tightening direction (i.e. movement of the device 10 andbase 16 towards the left shown inFigures 10 and11 ). - Release of the tightening
lever 42 causes the tighteningmember 35 to pivot back about thepivot 38 and the bar 37 (which is pushed back up towards the top of theslots tooth 39 is raised out of engagement with the perpendicular wall of the tooth 14 of the ratchet-type strap 12 ready to re-engage with another tooth 14 of the ratchet-type strap 12 upon a second lifting of the tighteninglever 42. This process can be repeated as many times as necessary by the user to achieve the appropriate tightness for the fastening. - It can seen that the
spring 46 provides a pressure against thebar 37 within theslot 48. This biases the device into a ratchet-engaging configuration (as illustrated, in particular, inFigures 5 and6 ). Release and tightening of the device 10, by contrast, require the user to exert some pressure on either therelease lever 34 or the tighteninglever 42 respectively. This mechanism provides an extremely simple device for providing a secure closure suitable for use on sport-type footwear. In particular, only a single biasing means (thehelical spring 46 in the above embodiment) is required and the arrangement between the ratchet-engagingmember 30 and the tighteningmember 35 provides that all of the necessary functionality can be achieved with as few component parts as possible. - The skilled person will, of course, appreciate that various modifications may be made to the above-described embodiment and that various items of the proposed embodiment may be varied or exchanged without departing from the scope of the invention.
