8 Claims. (Cl. 73-133) The present invention comprises a device for measuring or gauging the tolerable torque between a boot and a ski both in terms of horizontal twisting motion about the heel of the boot, and vertical rotary motion about the toe of the boot, tending to separate the boot from the ski at the heel thereof.
It is well recognized that many skiing accidents are due to a ski being fastened too rigidly to the associated boot. Hence, ski harness of various designs has included arrangements foradjusting the resistance to separation under stress between a ski and a boot in the two directions aforesaid. However, as far as has been ascertained, no invention has been designed for measuring the torque required to separate a boot from a ski responsive to tightening variations applied to the associated harness whereby it is possible to effect release of the boot from the ski at any preselected torque such as it is possible to do with the present invention.
A further object of the present invention is to provide a device of the character herewithin described which will foster the establishment of a tolerable torque standard for various persons of different weights and age either by the medical profession or responsible ski association or institute, to the end that skiers may use the present invention in association with such standard, and set their harness to release the boot from the ski according to standard data for their type, and hence reduce the incidence of injuries both as to quantity and severity.
The present invention has further applications such as in the making of equal (or measurably different) settings for both skis, and detecting the malfunctioning of harness, to mention just two of the uses which would be recognized readily by persons of skiing experience. In addition, the invention in all the three embodiments herein exemplified, is conspicuously simple to manufacture, assemble and use, being also capable of sale at a reasonable price, and free of any requirement such as replacement parts, servicing or the like.
With the foregoing objects in view, and such others as may become apparent as this specification proceeds, the present invention consists of the following arrangement and construction of parts all as hereinafter more particularly described, reference being made to the accompanying figures in which:
FIGURE 1 is a perspective representation of a simple and preferred embodiment of the present invention.
FIGURE 2 is a plan representation of the embodiment of FIGURE 1 in situ and in plan, showing the said device as applicable to measuring torque at the toe of a ski boot in a plane parallel to that of the ski.
FIGURE 3 is a view similar to FIGURE 2 but at right angles thereto and intended to indicate the manner of use of the embodiment of FIGURE 1 as applied to measure vertical stress between the heel of a ski boot and the ski.
FIGURE 4 is a detail on the line 4-4 of FIGURE 1.
FIGURE 5 is a plan representation of an alternative embodiment of the present invention.
FIGURE 6 is an elevational representation of the embodiment of FIGURE 5 depicting the use of same as applied to the heel of a boot.
FIGURE 7 is a front elevation of a further embodiment of the present invention as primarily designed for use in sports stores where skiing equipment is sold, and at skiing resorts where maintenance, renting and the like facilities are maintained, this figure illustrating the manner in which horizontal torque is applied against the toe of a boot.
FIGURE 8 is a representation of the modification of the invention depicted in FIGURE 7 but illustrating the manner of use thereof as applied against the heel of a ski boot.
FIGURE 9 is a view on the line 99 of FIGURE 7.
In the drawings like characters of reference designate similar parts in the several figures.
Describing first the embodiment of the accompanying FIGURES 1 through 4, it will be seen that what is there represented comprises a hollow cylindrical bearing portion 1 to the upper end portion of which is affixed load moving means collectively designated 2, and, at right angles thereto effort applying means collectively designated 3. Also projecting from member 1 is a pointer 4 constituting part of indicating means collectively designated 5. R0- tatably secured to the lower end of member 1 by means of the keyed stub-shaft 6, are device setting means collectively designated 7, the same, in this embodiment taking the form of a ski traversing stirrup provided with an upwardly projecting shoulder 8 designed to bear against the edge 9 of a ski 10, while the portion 10' extends across and beneath the ski as clearly depicted in the accompanying FIGURE 2.
Load moving means 2, and effort applying means 3-, in addition to being rigidly secured to the upper end of member 1 are preferably in right-angular relationship. Considered in detail, means 2 constitute a lever conformed at the distal end 11 thereof in the manner most clearly depicted in the accompanying FIGURE 1; that is to say is bifurcated to receive the swingable heel-lift component 12 journalled at the bifurcated end by means of the lug and stub- shaft details 13 and 14 respectively.
Effort applying means 3 embody a shaft 15 which is flexible under stress being secured in a short sleeve or collar 16 integral with member 1. Upon the end of shaft 15 is a handle 17 for convenient manual operation of the present device, but interposed between shaft 15 and handle 17 is a scale block 18 constituting part of indicating means 5. Scale block 18 is most clearly depicted in the accompanying FIGURE 4 from which it will be observed that the actual reading scale 19 thereon is slightly adjustable laterally by virtue of the provision of countersunk bolts 20 engageable with internally screwthreaded sockets 21 projecting from the rear side of plate 19 into cavities 22. These cavities, together with the apertures 23 within which bolts 20 are received, provide a tolerance for the said bolt and socket assemblies. In this way indicating needle 4 can be accurately zeroed.
The accompanying FIGURES 2 and 3 indicate sufficiently the manner in which the first embodiment of the present invention is employed for testing the tolerable torque between a boot and a ski, at the toe and at the heel of the latter respectively. There are many different forms of ski harness collectively designated 24 but all operate to the same end which is to maintain a rigid connection between boot and ski, which connection is only intended to be broken when excessive stress is applied between boot and ski either in parallel horizontal planes as indicated by arrow 25 of FIGURE 2, or in right-angularly related planes as indicated by arrow 26 of FIGURE 3.
One manner in which the toe 27 of a boot 28 is secured to ski 10 against horizontal rotation is conventionally designated at 29. The arcuate toe-bearing plate 30 exerts pressure against the front end of the sole 31 of boot 28. It swings about pivot point 32 via plate 33. Detail 34 including the adjustable screw 35 constitutes means whereby, upon rotation of the latter, varying resistance to yielding, of the toe-plate 30 may be achieved.
In light of the last foregoing explanation, it will now be apparent that in order to gauge the stress in pounds at which plate 30 should yield, load moving means 2 are caused to lie against the sole 31 of boot 28 in the toe region thereof while setting means 7 under-span the ski as aforesaid. At this point it will be observed that the distal end 11 of means 2 is slightly stepped-back at 36 in order the more conveniently to accommodate the toe portion of sole 31 at the corner thereof. Heel piece 12 is swung out of position for horizontal torque testing. If now an effort be applied to handle 17 in the direction of arrow 37, it will be apparent that shaft 15 will deflect while needle 4 remains straight, portion 8 acting as the fulcrum of a lever system in the toe testing position while the lever constituting the principal component of load moving means 2 bears clockwise against the edge of the boot sole in the manner by now clearly apparent.
To operate the first embodiment of the present invention with respect to the heel 38 of boot 28, setting means 7 are swung out of use. Then toe-piece 12 is inserted between heel 38 and the ski. Now handle 17 is urged counter clockwise as indicated by arrow 39. Thus in this use of the device, member 1 functions as the fulcrum, and when suflicient stress is applied to handle 17, boot 28 obviously yields upwardly at the heel, and about the toe portion so that the heel clamping portion 40 of any conventional harness 24 may be adjusted to yield at the requisite stress attainment measured in pounds on scale 19.
In the econd embodiment of the present invention as illustrated in the accompanying FIGURES and 6 there is shown load moving means collectively designated 41 in the form of a rectangular, double angulated bracket 42 having an underplate 43 intended to be inserted between sole and ski, an intermediate vertical portion 44 which bears against the edge of the sole, and an upper flange 45 to which is secured a toe-cap overspanning portion 46 connectible by means of ring 47 to indicating means collectively designated 48 and taking the form of a slotted and spring-loaded barrel 49 suitably scaled as at 50 and terminating in a pulling handle 51, it being understood that pointer 52 is suitably connected to a spring within barrel 49 so that upon the application of tension to handle 51, relative movement takes place between pointer 52 and slot 53.
In the use of this embodiment for testing heel stress, there is substituted for the toe-cap overspanning portion 46, a species of clevis 54 taking the form of U-shaped portion 55 designed to extend downwardly on either side of the rear portion 56 of boot 28, being of course engageable with ring 47 as shown, and terminating at the base in the angular heel lift 57 insertable between boot heel and ski, being secured to the lower ends of the U-shaped portion 55.
Obviously upon the application of an upward effort, parting stress at the heel of a boot may be accurately measured with respect to the associated ski.
In the embodiment illustrated in the accompanying FIGURES 7 through 9 there is depicted a third variation of the inventive concept disclosed in the present application. In this embodiment a mounting structure collectively designated 58 is usable horizontally as in FIG- URE 7 or vertically as in FIGURE 8. Such mounting structure comprises an elongated plate terminating at one end in an upstanding projecting portion 59 which, in horizontal stress measurement functions as a fulcrum like detail 8 of FIGURE 1, but in vertical use functions as a foot for supporting the mounting structure, rotatable extensions 59' being provided to stabilize this embodiment against overturning as best illustrated in FIG- URES 8 and 9. At the opposite end of mounting structure 58 is a right-angularly related bearing plate 60 having journalled therewithin a keyed, rotatable, internally screw-threaded bushing 61 projecting from which is a handle 62.
Mounting structure 58 also includes at the left end thereof with respect to the accompanying FIGURE 7, what is designated in one or more of the claims appended hereto as a load supporting stirrup 63 when such structure is employed for measuring torque in horizontal planes. Sustained upon the mounting structure and to the right of the portion 63 is a load moving assembly collectively designated 64 including an end component collectively designated 65 engageable selectively either against the edge 66 of the sole 67 of boot 28 in the toe region thereof, or between said boot and ski 10 in the heel region. Such end component comprises the upstanding fish plate 66 and bearing plate 67 secured at right angles thereto for lifting the heel of boot 28. From the accompanying FIGURE 8 it is apparent that both the projecting end portion 68 of plate 67 and the pair of extensions 59 are insertable between boot-sole and ski as aforesaid.
The effort applying means in this third embodiment are collectively designated 69 and may be said to constitute the shaft 70 splined and keyed as at 71 upon support 72 against rotation, the opposite end of such shaft being screw-threaded as at 73 for endwise movement under the rotary influence of bushing 61.
Load moving assembly 64 also carries at the opposite end thereof to that to which end component 65 is secured, a collar 74 through which shaft 70 extends. Projecting from this collar is a pointer 75 constituting part of indicating means for measuring stress, collectively designated 76 and including the double angulated bracket 77, which in turn comprises a scaled bar portion 78, and end supports 79 and 80 the lower ends of which encircle, and are keyed against end shifting movement to, shaft 70.
The portion 81 of shaft 70 which is encircled by collar 74 is of greater diameter than the remainder of the shaft. It will also be observed that secondary collars 82 and 83 encircle shaft 70 on either side of portion 81. Between these secondary collars and the shaft encircling collar portions 84 and 85 of parts 79 and 80 are springs 86 and 87.
From the foregoing it will be apparent that, in relation to the accompanying FIGURE 7, rotation of handle 62 clockwise from the position in which portion 81 is centered with respect to collar 74, shaft 70, in moving leftwardly causes compression of spring 86 (in virtue of the keyed portion 84 which is the agency causing such compression against collar 83). Scale bar 78 obviously also moves leftwardly from the Zero point 88 and hence the amount of pressure required to cause boot 28 to swivel about the heel thereof under the influence of portion 67 can conveniently be measured.
When the third embodiment of the present invention now being described is employed in the vertical position of the accompanying FIGURE 8 to lift heel 33, it will be apparent that handle 62 is to be rotated counter clockwise. By rotation in such direction spring 87 is compressed under the influence of the keyed shaft encircling sleeve portion 85. At the same time a scale bar 76' travels in the opposite direction. Hence it is to be understood that both in the first and third embodiments of the present invention, the markings on either side of the zero point 88 stand for the same amount of stress in one direction as the other.
What I claim as my invention is:
1. A device for measuring the torque between a boot and a ski comprising in combination load moving means in the form of a load bearing arm one end of which is bearable against said boot, device setting means connected to and co-acting with said load moving means for positioning and holding said device against said ski, an effort applying resilient arm, a rigid indicator r-od, said load bearing arm and said resilient arm being fixed immovably relative to each other in angular relationship at one end of each, the end at which said load bearing arm is fixed being opposite to that which is bearable against said boot, said indicator 'rod being fixed immovably relative to said load moving means to the junction of said two arms to lie parallel with said resilient arm, and a measuring scale adjacent said rod whereon the extent of deflection of said resilient arm relative to said rod may be read.
