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.

, is a longitudinal section, partly truncated, showing a pole grip with a wrist strap that can be snapped in releasably, in accordance with a preferred exemplary embodiment of the present invention;
FIG. 2
is a view, partly in section, in the direction of arrow II of
FIG. 1
; and
FIG. 3
is a section taken along the line IIIāIII of FIG.
1
.
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
.
