Primary Examiner-Leo Friaglia Assistant Examiner-Milton L. Smith Att0rneyClarence A. OBrien and Harvey B. Jacobson ABSTRACT: A ski pole having an upper hollow end providing a liquid container. The contoured handgrip is readily applicable and removable, and is provided with a latch-controlled locking device. The handgrip when removed permits partial withdrawal of a flask for drinking use. In addition, the locking device functions as a safety release if the basket at the pointed lower end of the ski pole should become snagged on a tree, a bush or other obstruction.
SKI POLE CONSTRUCTION WITH LIQUID RESERVOIR This invention relates to a ski pole whose lower pointed end is of ordinary construction and whose upper end features a special purpose chamber which is lined by an insertable and removable plastic drinking flask and is provided with a readily applicable and removable handgrip, more particularly, a handgrip which is lined with a suitable sleeve whose projecting lower end is provided with a conveniently accessible locking device embodying a manually regulatable latch.
Briefly, the elongated ski pole is rigid and is characterized, explicitly stated, by an upper end portion, a lower end portion and an intervening or median portion interconnecting said upper and lower end portions. The lower end portion has a pointed terminal end and is provided above the pointed end with a fixedly mounted basket-type guard. The handle means embodies an elongated sleeve which is fitted into and lines the axial bore or socket of a molded suitably contoured handgrip. The sleeve is such in length and cross-sectional dimension that it fits removably and telescopingly over the cooperating upper end portion of the pole. This upper end portion is hollow and serves to define a chamber, more specifically, a chamber which is adapted to receive an insertable and removable plastic container. This container is referred to herein as a liquid-containing and drinking flask. The upper end of the container has an outstanding liplike flange which abuts the coacting upper end of the ski pole. The upper end of the sleeve is provided with an insert made of wood or the like and which is faced with a compressibly resilient washer which constitutes a gasket and abuts and seals the upper flanged'end of the flask. The lower end of the sleeve is provided on one side with retainer means, that is, a special adaptation which functions to retentively but releasably mount and secure the sleeve and handgrip on the upper portion of the ski pole. To the ends desired, the retainer means is preferably in the form of a bracket having a pivoted lever, the lever having a cam acting on a spring which in turn acts on and frictionally retains a shoelike detent against the surface of the ski pole.
One improvement has to do with the readily applicable and removable handle means having the usual hand strap at an upper end and a protruding sleeve at the lower end which is equipped with the aforementioned retainer. The retainer is such that the trip lever actuates a cam and the cam acts on a spring carrying a friction gripping and clamping detent or shoe. With this arrangement the handle functions as a safety release device should the commonly used basket on the ski pole get snagged on a tree, bush or other obstruction. The handle or handgrip can be released and slipped off the ski pole with a view toward minimizing the likelihood of injury to the skiers arms or shoulders as the case may be.
As is perhaps already evident and aside from the safety type handle means, the removable grip portion of the handle means is provided with a closure which is in turn equipped with a gasket, the gasket being pressed and latched tightly against a limit stop and positioning flange on the upper end of the insertable and removable container or flask, thus sealing the contents of the container against leakage.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
FIG. 1 is a view in perspective of a ski pole constructed in accordance with the invention and readied for use.
FIG. 2 is a view on an enlarged scale showing the handle means released and bodily removed, showing the upper end portion of the hollow or chambered ski pole and showing the flanged upper end portion of the container or flask lifted out and projecting to a conveniently usable position.
FIG. 3 is an enlarged section with parts in section and elevation taken approximately on the plane of the vertical section line 3-3 of FIG. 1 looking in the direction of the arrows.
FIG. 4 is an enlarged detail elevational view showing the latch-equipped retainer means, that is a view observing this means in FIG. 3 in a direction from right to left and appearing in elevation.
And FIG. 5 is a horizontal section taken approximately on the plane of the section line 5-5 of FIG. 3.
Taking up first the ski pole it will be evident that it resembles any ordinary or conventional type ski pole, It is denoted, generally stated, by the numeral 6 and embodies a median or body portion 8 of requisite length and cross section, a complemental lower end portion 10 having a pointed terminal or leading end 12 and an upper portion 14. This upper portion 14 as better shown in FIG. 3 is hollow and provides a cylindrical chamber of uniform dimension from end to end. The extreme upper end of this hollow portion is denoted at 18 and provides a shoulder which serves in a manner to be described. The lower portion is provided above the point with an appropriate guard such as is commonly referred to as a basket and is denoted for convenience of reference by the numeral 20. Thus the ski pole 6 except for being hollow at the upper end portion is not unusual.
The chamber 16 is such as to accommodate an insertable and removable telescopingly fitted plastic elongated container which is denoted by the numeral 22 and which has a pointed lower end 24 (FIG. 3) and has an upper flanged end 26, the flange providing an annular lip and said lip being normally seated on the shoulder 18 when the container is fitted and sealed in place as shown. The container or flask lends itself to use as a receptacle for a liquid beverage or for whatever purpose the skier finds use therefor. Manifestly with this type of snug fitting but removable container it is desirable that the handle means, denoted generally by the numeral 28, must be such in construction as to provide a satisfactory retaining and sealing device.
In carrying out a preferred embodiment of the handle means it comprises an elongated open-ended sleeve 30 which is fitted snugly but removably over the coacting upper end portion 14 of the ski pole. The upper end portion of the sleeve is provided with a wooden or an equivalent filler or plug 32 which functions as a stopper or closure and which is faced with a compressibly resilient gasket 34 which fits atop the flange and provides a satisfactory seal when the parts are assembled in the manner shown in FIG. 3.
The major upper end and body portions of the sleeve are fitted within and serve to line the socket or bore of a molded plastic or equivalent handgrip which is denoted, generally stated, by the numeral 36. The extreme upper closedend of the grip is denoted at 38 and is provided with an axial hole 40 permitting access to be had to a screw 42 which is used to fasten an end portion 44 of a hand strap 46 in a radial hole 48 provided therefor, The lower end portion of the sleeve. denoted at 50 projects beyond the corresponding lower end 52 of the handgrip where it is provided with an integral or permanently attached retainer means. More specifically the retainer means comprises a bracket embodying a pair of spaced parallel ears 54 provided with a pivot pin 56 which serves to hingedly mount the cam-equipped end portion 58 of a lever-type latch 60. The latch, that is the handle portion, is accessible for easy use and functions to retentively apply the cam nose 58. When pressed in place the nose is engageable with a median portion of a suitable leaf spring 62 which has inturned or laterally directed end portions 64. This spring is provided intermediate its ends with a suitably attached disclike friction shoe or detent 66. This detent is of a shape that it can be pressed firmly against the surface of the ski pole in a manner to retentively but releasably latch the sleeve portion of the handle means 28 in its set position, that is the position shown in FIGS. 1 and 3 in particular.
This handle means as already suggested constitutes a safety release device in the event that the basket 20 on the ski pole should become snagged in any way on a tree, a stump, a bush or other obstruction. With the construction and arrangement shown, the handle can be released so that it will slip off the ski pole thus saving injury to the skiers arms and shoulders. The brass or equivalent detent 66 functions as a friction shoe and is carried on the spring means 62 and the spring means is forced into a secured position by moving the cam 58 of the lever 60 to the position illustrated in FIG. 3. The latch can be released to assume the position shown in FIG. 2 whereupon the handle means 28 can be slipped off either for safety purposes or to uncover the flask 22 so that it can be withdrawn in the manner shown in FIG. 2 for readily accessible and sanitary drinking purposes. In fact the entire container can be withdrawn and cleansed from time to time and restored for acceptable use.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
