Description




BACKGROUND OF THE INVENTION




The present invention relates to a ski pole grip, in particular for cross-country poles, having a wrist strap, which is releasably lockable to the pole grip via a first connecting element that is fixed to the wrist strap, and a second connecting element cooperating with the first connecting element, provided in a pole grip recess and movable counter to resilient bearing by means of an actuating member that is accessible in the region of the grip head.




In one such pole grip, known from German Patent DE 196 36 852 C1, the pole grip recess is accessible from a circumferential side for the first connecting element solidly connected to the wrist strap, and is covered on the face end of the grip head by a release cap and the actuating member. The actuating member is movable in the axial direction of the pole grip and is coupled with the second connecting element for the sake of axial motion of the second connecting element. In this known pole grip, the inlet and outlet of the pole grip recess are accordingly disposed perpendicular to one another, which is appropriate in designing downhill ski poles, in particular, since the pole grips for such poles are typically provided with a slightly curved grip head face end extending substantially perpendicular to the axis of the pole.




OBJECT AND SUMMARY OF THE INVENTION




The object of the present invention is to provide a pole grip of the type defined at the outset whose releasable wrist strap fastening is adapted to the preferably slenderer forms of cross-country ski pole grips and is released in a structurally simpler way.




To attain this object, in a pole grip of the type defined at the outset, the inlet to the pole grip recess into and out of which the first connection element can be introduced and retracted, is disposed in an approximately rectilinear alignment with the outlet of the pole grip recess, in whose region the actuating member is actuatable.




By the provisions according to the invention, because of the approximately rectilinear alignment, a structurally simpler capability of releasable locking of the two connecting elements inside the pole grip recess is obtained. Moreover, the face end of the grip head of the cross-country ski pole can be designed in a more versatile way.




By disposing the pole grip recess at an acute angle to the longitudinal axis of the pole grip, or of the pole tube connected to it, or by providing the inlet to the pole grip recess on a circumferential region and providing the outlet of the pole grip recess on a leveled grip head end of the pole grip; or protruding the actuating member past the outlet of the pole grip recess, it is attained that the capability of locking the wrist strap in the pole grip does not increase the diameter of the pole grip; that is, the pole grip can be kept very slender. Nevertheless, designing the upper free end of the pole grip is advantageously possible.




Advantageous handling of the release of the locking is obtained if the by forming the actuating member as a lever pivotably supported in the pole grip recess. The actuating lever is disposed on the one hand in such a way that it cannot be actuated unintentionally, yet nevertheless in such a way that one-hand operation is possible.




Advantageous and simple constructive provisions are obtained from the emboding the actuating member as a lever and forming it and the second connecting element as, one piece, or by pivotably connecting the actuating lever between the pivot axis and the outlet of the pole grip recess with a spring, or by providing a spring which is based on an inner wall region of the pole grip and which presses the actuating member against a wall region of the pole grip that defines the outlet of the pole grip recess.




Advantageous features of the connecting elements and their disposition inside the pole grip recess are realized in that the first and second connecting elements are provided with lugs that interests with one another, or in that the first connecting element, in the state in which it is thrust into the pole grip recess is braked on an inner guide face of the pole grip, or in that the inner guide face is provided with a stop.




Further details of the invention can be learned from the ensuing descriptions, in which the invention is described and explained in further detail in terms of the exemplary embodiment shown in the drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT




The pole grip


10


shown in the drawing in terms of a preferred exemplary embodiment has a base body


12


, made for instance from a plastic injection-molded part. The base body


12


may, as shown in the drawing, be provided with a sheath


14


of material suitable for a hand grip. The pole grip


10


is slipped onto and over a pole tube


16


of a cross-country ski pole and is solidly joined to it, preferably being adhesively bonded or pressed onto it.




The base body


12


of the pole grip


10


is embodied approximately cylindrically in a lower region


18


, but is disposed eccentrically to the longitudinal axis


17


of the pole tube


16


, as can be best seen from FIG.


3


. The upper end region


20


of the base body


12


of the pole tube


10


is conversely provided with an approximately oval form in end view as seen in

FIG. 2

, which in a manner not shown changes over continuously in a middle region, approximately below the free end of the pole tube


16


, into the cylindrical shape. The upper end region


20


is inclined in a lateral direction relative to the longitudinal axis


17


as shown in

FIG. 1

; the short sides of the oval form are slightly curved. The end of this upper region


20


has an end head face


22


, which in the direction of its narrow dimension extends straight and in the direction of its longer dimension is curved slightly concavely, and extends at an acute angle to the longitudinal axis


17


.




Aside from and axial cylindrical hollow chamber


24


in the lower end region


18


for receiving the end of the pole tube


16


, the base body


12


has a recess


26


in the upper end region


20


, specifically at a specific spacing above this cylindrical hollow chamber


24


, that is embodied substantially rectangularly with different cross sections. The width of the recess


26


is approximately the same, while its height is in part graduated and in part widens in fanlike fashion. The recess


26


extends from a substantially rectangular inlet


28


, which is provided on a short side of the base body


12


, to a substantially likewise rectangular outlet


30


, which is located in the obliquely extending end face


22


of the grip head. Since the access opening


28


is located in a region somewhat above the bottom of the cylindrical hollow chamber


24


in the base body


12


, the recess


26


extends in a direction that is at an acute angle to the orientation of the longitudinal axis


17


.




As mentioned, side faces


32


and


33


that define the recess


26


extend substantially parallel between the access opening


28


and the outlet opening


30


. By comparison, a stepped bottom face


34


that defines the recess


26


extends from the access opening


28


slightly concavely inward and forms a step at a stop face


36


, facing toward the access opening


28


, after which it extends straight in approximately the same direction to the outlet opening


30


. A top face


35


that defines the recess


26


extends at such an angle to the bottom face


34


that the recess


26


widens from the access opening


28


to the outlet opening


30


. The top face


35


extends relatively steeply in a first and second portion


39


,


40


and more shallow in a third portion


41


toward the outlet opening; all the portions


39


,


40


,


41


are straight.




Inside the recess


26


, near the first portion


39


of the top face


35


, a pivot axis


42


is defined, which is retained in the base body


12


and traverses the recess


26


between the side faces


32


and


33


. A one-armed lever


44


is pivotably connected by its one end


46


at the pivot axis


42


, while the free end


48


of the lever


44


protrudes out of the outlet opening


30


of the recess


26


. This actuation end


48


is connected at an obtuse angle to the inner end


46


via an intermediate part


47


. The outside


50


of the lever


44


, which is oriented toward the top face


35


, corresponds in its course to the top face


35


.




The lever


44


is acted upon by a compression spring


52


, one end of which extends inside the recess


26


at the intermediate part


47


of the lever


44


and the other end of which extends into a bore


54


, originating at the top face


35


, and is braced on a stop formed in this exemplary embodiment by a screw


56


introduced from outside into the base body


12


. The compression spring


52


, which has a somewhat curved course and which in the lever


44


extends into a blind bore


58


, prestresses the lever into a position of repose, in which the actuation end


48


presses against the bottom face


34


at the outlet opening


30


. The lever


44


is pivotable about the axis


42


as indicated by the double arrow A; the pivoting is limited by the top face


35


.




A wrist strap


11


is releasably lockable to the pole grip


10


; of the wrist strap,

FIG. 1

shows only the fastening portion


62


of a strap


60


. A connecting element


64


, which is somewhat cleatlike and is made from a suitable plastic, has a slit


66


on its back side that receives the fastening portion


62


of the strap


11


, which slit is penetrated by a pin or screw


68


, retained in the fastening element


64


, so that the strap


60


is solidly joined to the connecting element


64


. The connecting element


64


, which is approximately rectangular in cross section, has a unilaterally protruding detent lug


70


on its front end. At the lateral faces perpendicular to the detent lug


70


, the front end of the connecting element


64


is designed slightly conically, for the sake of introduction into the access opening


28


of the recess


26


. The external cross-sectional dimensions of the connecting element


64


match the internal cross-sectional dimensions of the access opening


28


of the recess


26


, so that the connecting element


64


can be introduced into and retracted out of the recess


26


, as indicated by the double arrow B and the positions represented by solid and dot-dash lines in

FIG. 1

, along with the strap


60


of the wrist strap


11


without substantial play yet still smoothly. For locking the connecting element


64


to the lever


44


inside the recess


26


of the base body


12


of the pole grip


10


, the inner end


46


of the lever


44


is embodied as a counterpart detent element, with a sawtooth detent lug


45


protruding from the inside.




If the connecting element


64


, retained on the wrist strap


11


, is pushed out of the dot-dashed position of FIG.


1


through the access opening


28


into the recess


26


of the pole grip


10


, the lug


70


slides with its face


71


along the sawtooth face


72


of the detent lug


45


of the lever


44


and, supporting itself on the bottom face


34


, presses the lever


44


into a position equal to or near the dot-dashed position counter to the action of the compression spring


52


. At the end of this introduction motion, that is, when the stop face


36


is reached by the connecting element


64


, the detent lug


45


comes from of the connecting element


64


at the inner end


46


, so that under the influence of the compression spring


52


the lever


44


is pressed into its outset position or position of repose represented by solid lines. As a result, locking of the connecting element


64


behind the detent end


46


of the lever


44


is achieved. A release of the locking is accomplished in correspondingly reverse order by moving the lever


44


out of its position of repose shown in solid lines into its release position shown in dot-dash lines, in which the wrist strap


11


can be pulled along with the connecting element


64


out of the recess


26


. The detent release motion of the lever


44


can easily be accomplished with the index finger of one hand, for instance, while the hand is grasping the pole grip


10


.




Although the recess


26


has been shown and described as extending at an acute angle to the longitudinal axis


17


, it is understand that the recess


26


can also be disposed at an arbitrary other angle to the longitudinal axis


17


.
