Description

Technical Field

[0001] This utility model relates to a standing umbrella, which has a pole and at least three top umbrella ribs for folding the umbrella top. The pole has a longitudinal axis, and each top umbrella rib has a corresponding supporting umbrella rib with a lower hinge. The top umbrella rib is hinged to an upper hinge ring on the pole side, and the supporting umbrella rib is hinged to a lower hinge ring on the pole side that can move up and down on the pole. At least one supporting umbrella rib also has an upper hinged suspension umbrella rib connected to a central hinge ring fixed on the pole. The upper hinge ring has an upper hinge portion for the top umbrella rib arranged on an upper hinge circle with a first diameter, and the central hinge ring has a central hinge portion for at least one suspension umbrella rib arranged on a central hinge circle with a second diameter. The lower hinge ring has a lower hinge portion for the supporting umbrella rib arranged on a lower hinge circle with a third diameter. Background Technology

[0002] Various standing umbrellas are known, which have an upper umbrella section that can be raised and lowered relative to a fixed upright. In some embodiments, the umbrella section is arranged on the upper end of a member that can extend and retract within the upright, particularly a telescopic tube or telescopic rod.

[0003] Such a standing umbrella is described in EP 2397044 B1. This standing umbrella has a pole and a foldable canopy with top ribs and supporting ribs, wherein the top ribs and supporting ribs are connected to a lower hinge ring and an upper hinge ring, respectively. The upper hinge ring is connected to a height-adjustable telescopic tube guided in the pole, while the lower hinge ring is fixedly mounted on the pole. The lifting and lowering movement along the pole's axis is achieved by a drive unit located in the pole, which can be operated, for example, by a hand crank.

[0004] In principle, a corresponding structure without a telescopic tube can also be used, as long as there are at least three top umbrella ribs and supporting umbrella ribs to keep the mobility of the upper hinge ring basically in the direction of the rod axis.

[0005] An improved version of the aforementioned upright umbrella is also known, wherein the lower hinge ring is movable up and down on the upright, and at least one supporting rib has an upper-hinged suspension rib connected to a central hinge ring fixed to the upright. For this type of upright umbrella, opening and closing can be performed manually, thus eliminating the need for a drive unit in the upright.

[0006] The last disadvantage of this type of stand-up umbrella is that, in the open (spread) position, the central hinge ring and the upper hinge ring are spaced apart. This results in the uppermost section of the telescopic tube remaining exposed even in the open position and thus particularly susceptible to dust and wind-blown rain. In implementations without a telescopic tube, undesirable lateral swaying may occur, especially in windy conditions. Utility Model Content

[0007] Therefore, the technical problem to be solved by this utility model is to propose an improved standing umbrella that can overcome the shortcomings of the prior art.

[0008] This technical problem is solved in the type of upright umbrella mentioned at the beginning by having the central hinge ring and the upper hinge ring essentially closed when the upright umbrella is in the open position.

[0009] The standing umbrella according to this utility model has a pole with a longitudinal axis A and at least three top umbrella ribs for folding the umbrella top, wherein each top umbrella rib has a corresponding supporting umbrella rib hinged to its lower side. The top umbrella rib is hinged to an upper hinge ring on the pole side, and the supporting umbrella rib is hinged to a lower hinge ring on the pole side that can move up and down on the pole. At least one supporting umbrella rib also has an upper hinged suspension umbrella rib connected to a central hinge ring fixed to the pole. The upper hinge ring has an upper hinge portion for the top umbrella rib arranged on an upper hinge circle having a first diameter D1, the central hinge ring has a central hinge portion for at least one suspension umbrella rib arranged on a central hinge circle having a second diameter D2, and the lower hinge ring has a lower hinge portion for the supporting umbrella rib arranged on a lower hinge circle having a third diameter D3.

[0010] At least the disadvantages mentioned at the beginning can be avoided by ensuring that, in the open position of the upright umbrella, the central hinge ring and the upper hinge ring are essentially closed.

[0011] The term "standing umbrella" should be interpreted in the broadest sense, especially including various pole-supported parasols used outdoors, particularly center-pole umbrellas with ribs, in which the opening or closing of the umbrella top is achieved by movement along the umbrella axis.

[0012] The term "substantially closed" should be understood as meaning that, in this state, the relevant components, namely the central hinge ring and the upper hinge ring, share a substantially gapless outer contour. "Substantially gapless" means that the two hinge rings ideally have at least one circumferentially continuous contact line or circumferentially continuous contact surface. Due to common manufacturing tolerances acceptable, for example, in injection molded parts, an air gap of approximately 1 mm may actually exist on the contact line or contact surface.

[0013] Advantageous design options are defined in the specification.

[0014] According to an advantageous embodiment, the upper hinge ring is connected to a telescopic member that is guided and raised / lowered within the upright. In this manner, the upper hinge ring is held on the longitudinal axis A, meaning that during the opening or closing of the upright umbrella, the upper hinge ring and the top umbrella rib hinged thereto, together with the telescopic member, move symmetrically relative to the upright axis.

[0015] In a different implementation, the upper hinge ring is designed to be suspended relative to the pole; that is, the upper hinge ring is not located on a telescopic member or similar component serving as a longitudinal guide. To hold the upper hinge ring on the longitudinal axis A, at least three rib groups are provided, distributed around the longitudinal axis A, wherein each rib group consists of a supporting rib, a corresponding top rib, and a corresponding suspension rib. Naturally, each rib group lies in a rib plane extending through the pole axis. Advantageously, but not mandatory, these rib planes are distributed around the longitudinal axis A at a uniform angular spacing.

[0016] For certain applications, it is particularly advantageous that the first diameter D1 of the upper hinge circle and the third diameter D3 of the lower hinge circle are both larger than the second diameter D2 of the central hinge circle. This allows for a particularly compact radial configuration in the closed position of the upright umbrella. This is advantageous not only for the closed upright umbrella in its working position on the pole but also for transportation. If the first diameter D1 is set to a value of 100%, then in some embodiments the second diameter D2 is approximately 50%-60% and the third diameter D3 is approximately 65%-75%.

[0017] In another embodiment, the standing umbrella is provided with a tensioning device for fixing the umbrella in its open position. This particularly achieves ideal tension at the top of the umbrella.

[0018] Advantageously, the tensioning device is designed as a traction mechanism with an upper and a lower end, wherein the upper end is fixed, particularly hinged, to an upper hinge ring, and wherein the lower end is provided with a handle portion that can be hooked onto the lower hinge ring and placed in a tensioned, fixed position. It is particularly advantageous here that this hooking is achieved by a guided snap-fit ​​that passes through a dead point. In some embodiments, the handle portion is not hooked onto the lower hinge ring, but rather onto a hook-up portion on the upright.

[0019] In another embodiment, the upper end of the traction mechanism is fixed to the upright above the lower hinge ring, and the handle is hooked onto the lower hinge ring.

[0020] In some embodiments, the tensioning device includes two or more traction mechanisms, which are advantageously arranged symmetrically around the umbrella axis.

[0021] The elements to be used according to the present invention as described above and in the following embodiments are not subject to any special exceptions in terms of their size, shape design, material selection and technical solutions, and can therefore be applied without limitation to the selection criteria known in the respective application fields.
