Abstract
Description
- This invention relatesto an actuator device for an instep presser, particularly useful in rear entrance ski boots.
- As is known, it is essential with rear entrance ski boots that the skiers foot instep be firmly secured. To this aim, a presser is provided on the boot shell interior which is operated to exert a desired locking pressure on the instep region.
- To achieve that locking action, US-A-41 60 332 proposes to use a cable acting on the pressure element to squeeze it against the user's foot, which cable is controlled, i.e. placed under tension, through a pivotal movement of the boot rear quarter which acts in practice as a lever element to apply a pulling force on the cable.
- The above prior construction is quite simple, but is unpractical and awkward to use because, to vary the pull exerted by the cable actuating the pressure element, the quarter requires to be opened.
- In other prior embodiments, such as those disclosed in a prior European Patent Application EP-A-0099504 No. 83106499.3 filed on July 4, 1983 by the same Applicant, which forms prior art within the meaning of Art 54(3), EPC, and incorporated hereto for reference, the cable which extends above the presser acting on the foot instep is connected with one end to a mechanism, located at the boot rear, which is rotated to wind and unwind cable around a reel.
- The mechanism includes a pinion gear and gear wheel drive effective to greatly reduce the effort required to apply a desired tension.
- The latter embodiment has the advantage of favoring an improved utilization of the device by its user, since pressure can be adjusted with the boot on and closed but involves, on the other hand, a more complex construction and the need for assembling a large number of component parts.
- It is an object of this invention to obviate such prior shortcomings by providing a device for actuating the foot instep presser, which can combine the advantages of known embodiments with freedom from their disadvantages.
- A further object of the invention is to provide such an actuator device which affords the ability to continuously adjust the pressure to be exerted by the presser by operating the presser with the boot in the worn condition.
- It is another object of this invention to provide such an actuator device which enables adjustment with quick and easy movements and requires no skill on the part of its user.
- Still another object of the invention is to provide a device for actuating the foot instep presser which, owing to its peculiar construction, can afford an increased degree of reliability and be safe to use.
- These and other objects, such as will be apparent hereinafter, are achieved by an actuator device for an instep presser, particularly useful in rear entrance ski boots, comprising a cable extending above a presser located inside the boot shell at the foot instep region and being attached with one end to a side point on the. shell and with the other end to an actuator element, characterized in that said actuator element includes a reel made rotatively rigid with a knob carried; for rotational and axial movements, on a fixed body associated with said shell, and that means are provided for releasably preventing rotation of said knob including front tooth formations, respectively providing on said fixed body and said knob.
- Further freatures and advantages will be more readily understood from the following detailed description of an actuator device for an instep presser, particularly useful in rear entrance ski boots, with reference to the accompanying illustrative drawing, where:
- Figure 1 is a diagramatic perspective view showing, partly in section, a ski boot incorporating the device of this invention;
- Figure 2 is an exploded perspective view of the inventive device; and
- Figure 3 is a diametrical section view taken through the cable take-up reel.
- With reference to the drawing views, an actuator device for an instep presser, particularly useful in rear entrance ski boots, according to the invention, comprises a
cable 1 running inside aflexible sheath 2. Thecable 1 is attached with one end, indicated at 3, to a side location within the boot shell 4 and runs above a foot instep presser, indicated at 5. - The
sheath 2 is connected, at its remote end from thefixed point 3, to aguide block 6 mounted on the inner side surface of the boot, at the opposed side to thefixed point 3. - The
cable 1 is connected, at its other end, to areel 10, and specifically to thepulley portion 11 of thereel 10 which is accommodated rotatably inside a fixedbody 15 attached to the rear portion of the boot shell 4 and provided with ayoke 16 which is coupled to asmall bushing 17 located at the end of thesheath 2 to guide thecable 1 as it is wound or unwound from thepulley portion 11 of thereel 10. - The
reel 10 has anaxial tang 12 which extends inside a bushingportion 18 defined axially within thefixed body 15. - The
reel 10 is made rotatively rigid with aknob 20 which is carried on thefixed body 15 for rotation and axial translation. - More in detail, the
knob 20 has an outercylindrical body handgrip 21 connected to an innercylindrical _body 22 which may be positioned around thebushing portion 18. - From the outer
cylindrical body 21 there extends an innerradial partition 23 which is inserted, for sliding movement in an axial direction, - into aslot 24 defined by asmall cover 25 adapted to be rigidly attached to thereel 10 through ascrew 26. - The
fixed body 15 has at the bottom of the bushing portion 18 a firstfront tooth formation 30 of sawtooth configuration which engages with a secondfront tooth formation 31 defined on the innercylindrical body 22. - Also provided are elastic means comprising a
spring 40 acting between thecover 25 andinner bottom 27 which joins the outercylindrical body 21 and innercylindrical body 22 together and holds the second tooth formation elastically pressed against the firstfront tooth formation 30, thus preventing theknob 20, and hence thereel 10, from turning. - In order to impose a tension on the
cable 1, it will be sufficient to turn the knob, for example, in a clockwise direction, whereupon owing to their particular configuration, thetooth formations - To relax the
cable 1, the knob should be shifted axially to disengage thetooth formations - It should be added to the foregoing that from the
knob 20, or more precisely, from the outercylindrical body 21, there may extend axially apeg 50 which functions as a rotation end stop in cooperation with a corresponding fixed detent defined on the shell to allow the knob to rotate axially at most through an angle of 360 degrees. - It may be appreciated from the foregoing description that the invention achieves its objects, and in particular, the fact should be emphasized that by connecting the
cable 1 to theknob 20, with the interposition of thereel 10, the structure can be considerably simplified, without using additional gearing or similar, alternative arrangements, while rotation in the cable slackening direction can be effectively inhibited by mutual engagement of thefront tooth formations - With the device of this invention, therefore, the user is enabled to adjust as desired through a wide range, the pressure to be applied by the presser 5, without becoming involved in complex or laborious operations, since disengagement of the knob from the
fixed body 15 can be simply achieved through an axial movement that sets thefront tooth formations - In practicing the invention, any suitable dimensions, contingent shapes or materials may be used to meet individual requirements, though the best results have been obtained using plastic materials.
