DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

[0030] As can be seen from the figures, the standing parasol according to the present invention comprises a parasol mast 2 and an actuating device 4 arranged thereon, which actuating device cooperates with a connecting organ 6 for moving a parasol part, not shown here, in particular a parasol roof.

[0031] The actuating device comprises a hand crank device 8, which is rotatable about a substantially horizontal axis of rotation A. The hand crank device 8 is coupled to the connecting organ 6 and comprises an associated crank handle 10, wherein the crank handle is formed in two parts with an inner handle portion 12 and an outer handle portion 14. FIG. 1 shows the basic arrangement of the hand crank device 8 on the parasol mast 2, while FIG. 2 illustrates an overview with further operating units of the standing parasol, which will be described later.

[0032] As can be seen in particular from FIGS. 3 to 6, the inner handle portion 12 is arranged substantially transversely to the axis of rotation, i.e. in radial direction, while the outer handle portion 14 is pivotable with respect to the inner handle portion between a substantially coaxial resting position and an angled functional position. As explained further below, the hand crank device 8 is rotationally connected to the connecting organ 6 in its functional position, whereas it is disengaged from the connecting organ 6 in the resting position.

[0033] The hand crank device 8 is provided with a restoring means generically referred to as 16, by means of which the outer handle portion 14 is urged into the resting position. As will henceforth be explained in more detail, this releases the rotationally connected engagement.

[0034] In the embodiment shown, the hand crank device is configured as follows.

[0035] The outer handle portion 12 is articulately connected, via a lug member 18, to a pin member 20 of the inner handle portion 12, wherein the lug member 18 is pivotable, with respect to the outer handle portion 14, about a first pivot axis G1 which is displaced parallel to the handle pivot axis G. Moreover, the lug member 18 is pivotable with respect to the pin member 20 about a second pivot axis G2 which is displaced parallel to the handle pivot axis G. Due to this arrangement, a pivoting movement of the outer crank handle 14 from the resting position to the functional position, causes the pin member 20 to be pushed from a basic position into a position protruding towards the crank axis of rotation.

[0036] Furthermore, the pin member 20 is provided with a follower pin 22 pointing towards the crank axis of rotation A, which the follower pin being urged by a first spring means 24 into a position protruding with respect to the pin member 20. In the situation shown in FIG. 6, the protruding follower pin 22 is partially inserted into a cam opening 28 of a rotary drum 26 rotatably connected to the connecting organ 6, the rotary drum with the cam opening not being shown in this illustration. During the transition into the functional position, the pin member 20 is further pushed towards the crank axis of rotation A, and the follower pin 22 is thus also completely inserted into the cam opening 28. In this situation, there is a rotary coupling between the hand crank device 8 and the connecting organ 6.

[0037] In contrast, in the resting position of the outer handle portion 14, the pin member 20 is maximally pulled back with respect to the crank axis of rotation A, and the follower pin 22 is thus located outside of the cam opening 24. Accordingly, the rotary coupling between the hand crank device 8 and the connecting organ 6 is disabled.

[0038] It shall be understood that the engagement of the follower pin 22 into the cam opening 28 is only possible when the rotary drum 26 is in the same rotary position. During the transition from the resting position into the functional position, the follower pin 22 will first rest against a side surface of the rotary drum 26. During rotation of the hand crank device, the follower pin 22 will then hit a cam opening 28 and penetrate thereinto. Therefore, it is advantageous, if the rotary drum 26 comprises more than one cam opening 28, for example three of them or even more.

[0039] Conversely, during transition from the functional position into the resting position, the follower pin 22 is pulled out of the cam opening 28 and is disengaged.

[0040] As can also be seen from FIGS. 5 and 6, in the example shown, the outer handle portion 14 comprises an inner pivot member 30 connected to the handle pivot axis G, and further comprises an outer grip sleeve 2 arranged concentrically and longitudinally displaceable thereto, which is urged against the handle pivot axis G by a second spring means 34. The function referred to generically as restoring means 16 is thus implemented.

[0041] In the arrangement just described, the hand crank device 8 in its resting position is substantially free-rotating. Accordingly, it can spontaneously assume a downward orientation parallel to the parasol mast 2. In the example shown, magnet means 36 are also present, which cause a soft securing of the downward pointing orientation.

[0042] As explained in more detail by means of FIGS. 1, 7 and 8, the actuating device 4 is integrated into an operating unit for further parasol functions.
