Description

Technical field

[0001] The invention relates to a standing umbrella according to the preamble of claim 1. State of the art

[0002] Several parasols are already known that have an upper canopy section which can be raised and lowered relative to a fixed support mast. In some embodiments, said canopy section is arranged at the upper end of a telescopic section within the support mast, in particular a telescopic tube or pole.

[0003] Such a standing parasol is described in EP 2397044 B1. It comprises a mast and a foldable canopy with roof and support struts, the roof struts and support struts each being connected to a lower pivot ring and an upper pivot ring, respectively. The upper pivot ring is connected to a telescopic tube guided within the mast, which can be raised and lowered, while the lower pivot ring is fixed to the mast. The raising and lowering movement, in the direction of the mast axis, is effected by a drive unit housed within the mast, which can be operated, for example, with a hand crank.

[0004] In principle, a corresponding construction without a telescopic tube can also be used, provided that at least three roof and support struts are present to keep the movement of the upper steering ring essentially in the direction of the mast axis.

[0005] Further developments of the aforementioned parasol are also known, in which the lower control ring on the mast can be raised and lowered, with at least one of the support struts being equipped with a suspension strut hinged at the top, which is connected to a central control ring attached to the mast. With this type of parasol, the opening and closing of the parasol can be done manually, so that no drive unit housed in the mast is required.

[0006] A disadvantage of the latter type of parasol is that, when the parasol is open (i.e., unfolded), the central and upper pivot rings are spaced apart. This means that the uppermost section of the telescopic tube remains exposed even when the parasol is open and can become covered with dirt and debris, as well as wind-driven rainwater. In designs without a telescopic tube, undesirable lateral wobbling of the parasol is possible, especially in windy conditions. Description of the invention

[0007] The object of the invention is therefore to propose an improved parasol which is able to overcome the weaknesses of the prior art.

[0008] This problem is solved by the parasol according to claim 1.

[0009] The parasol according to the invention comprises a mast with a longitudinal axis A and a plurality of at least three roof struts for a foldable canopy, each roof strut being provided with an associated support strut hinged to its underside. The roof struts are hingedly connected to an upper pivot ring on the mast side, and the support struts are hingedly connected to a lower pivot ring that can be moved up and down the mast. At least one support strut is also provided with a suspension strut hinged to its upper side, which is connected to a central pivot ring attached to the mast.The upper control ring is provided with upper pivot points for the roof struts arranged on an upper control circle with a first diameter D1, the middle control ring is provided with central pivot points for the at least one suspension strut arranged on a central control circle with a second diameter D2, and the lower control ring is provided with lower pivot points for the support struts arranged on a lower control circle with a third diameter D3.

[0010] Because the central control ring and the upper control ring are essentially moved together when the parachute is in an open position, at least the disadvantages mentioned at the beginning can be avoided.

[0011] The term "standing parasol" is to be understood in the broadest sense, but in particular includes various types of mast-supported parasols for outdoor use, especially center-pole parasols with canopy ribs, in which the opening or closing of the canopy is achieved by a movement along the parasol axis.

[0012] The term "essentially retracted" means that, in the specified state, the components in question—that is, the central pivot ring and the upper pivot ring—together have an essentially gap-free outer contour. "Essentially gap-free" means that the two pivot rings ideally have at least one continuous line of contact or a continuous contact surface. Due to typical manufacturing tolerances, such as those found in injection-molded parts, this line of contact or contact surface may, in practice, include an air gap of approximately 1 mm.

[0013] Advantageous configurations are defined in the dependent requirements.

[0014] According to an advantageous embodiment (claim 2), the upper pivot ring is connected to a telescopic section guided in the support mast, which can be raised and lowered. In this way, the upper pivot ring is held on the longitudinal axis A, i.e., when the parasol is opened or closed, the upper pivot ring and the roof struts articulated to it, together with the telescopic section, move axially symmetrically to the support mast.

[0015] In contrast, in another embodiment (claim 3), the upper pivot ring is designed to be suspended relative to the mast, i.e., it does not rest on a telescopic element acting as a longitudinal guide or the like. To hold the upper pivot ring on the longitudinal axis A, at least three sets of struts are provided, distributed around the longitudinal axis A, each set of struts consisting of a support strut, an associated roof strut, and an associated suspension strut. It is understood that each set of struts lies in a strut plane extending through the mast axis. Advantageously, but not necessarily, the strut planes are distributed at uniform angular intervals around the longitudinal axis A.

[0016] In some applications, it is particularly advantageous (claim 4) if both the first diameter D1 of the upper pivot circuit and the third diameter D3 of the lower pivot circuit are each larger than the second diameter D2 of the central pivot circuit. This allows for a particularly compact radial configuration when the parachute is closed. This is advantageous not only for the closed parachute in its working position mounted on the mast, but also for transport. If the first diameter D1 is assigned a value of 100%, then in some embodiments the second diameter D2 is approximately 50 to 60% and the third diameter D3 is approximately 65 to 75%.

[0017] In a further embodiment (claim 5), the standing umbrella is provided with a tensioning device for fixing the open position of the standing umbrella. This ensures, in particular, the desired tensioning of the umbrella canopy.

[0018] Advantageously (claim 6), the tensioning device is designed as a tensioning element with an upper end and a lower end, wherein the upper end is attached, in particular pivoted, to the upper pivot ring, and wherein the lower end is provided with a handle that can be hooked onto the lower pivot ring and brought into a tension-loaded locking position. It is particularly advantageous if the hooking is effected by a guided snap-in action beyond a dead center. In certain embodiments (claim 7), the handle is not hooked onto the lower pivot ring, but rather onto a hooking point on the support mast.

[0019] In a further embodiment (claim 8) the upper end of the pulling element is attached to the support mast, above the lower pivot ring and the handle part is hooked onto the lower pivot ring.

[0020] In certain embodiments, the tensioning device comprises two or even more tensioning elements, which are advantageously arranged symmetrically around the umbrella axis.

[0021] The aforementioned elements, as well as those claimed and described in the following exemplary embodiments, which are to be used according to the invention, are not subject to any special exceptional conditions with regard to their size, shape, use of materials and their technical conception, so that the selection criteria known in the respective field of application can be applied without restriction.

Ways to implement the invention

[0023] The in Figs. 1 and 2The parasol 2, known from the prior art, has a support mast 4 and roof struts 6 for a foldable canopy (not shown), each roof strut 6 being provided with a support strut 8 hinged to its underside. The roof struts 6 are hingedly connected at the mast end to an upper pivot ring 10, and the support struts 8 are hingedly connected to a lower pivot ring 12 that can be moved up and down the support mast 4. The support struts 8 are also provided with a suspension strut 14 hinged at their upper end, which is connected to a central pivot ring 16 attached to the support mast 4.The upper pivot ring 10 is provided with upper pivot points 20 for the roof struts 6, arranged on an upper pivot circle 18 with a first diameter D1; the central pivot ring 16 is provided with central pivot points 24 for the suspension struts 14, arranged on a central pivot circle 22 with a second diameter D2; and the lower pivot ring 12 is provided with lower pivot points 28 for the support struts 8, arranged on a lower pivot circle 26 with a third diameter D3. The upper pivot ring 10 is connected to a telescopic section 30, in the form of a telescopic tube, which is guided in the support mast 4 and can be raised and lowered.

[0024] As from the Fig. 3 As can be seen, in the open, i.e. unfolded position of the parachute, the central control ring 16 and the upper control ring 10 are clearly spaced apart from each other, see distance Δh in Fig. 3 .

[0025] As especially in the Fig. 2As illustrated, the diameter D1 of the upper control circuit 18, the diameter D2 of the middle control circuit 22, and the lower diameter D3 of the lower control circuit 26 are essentially identical. This means that when the canopy is closed ( Fig. 1 ) the roof struts 6 cannot be brought into a desired vertical resting position.

[0026] The in the Figs. 4 to 7 The first embodiment shown comprises largely the same components as the previously known parasol of the Figs. 1 to 3 The main difference is that, in the open position of the parachute, the central control ring 16 and the upper control ring 10 are essentially moved together, see Fig. 5 .

[0027] Furthermore, the first diameter D1 of the upper pivot circuit 18 and the third diameter D3 of the lower pivot circuit 12 are significantly larger than the second diameter D2 of the middle pivot circuit 22 (see Fig. 4 , Fig. 6 and Fig. 7 ), so that when the umbrella is closed, the roof struts 6 are in an approximately vertical rest position (see Fig. 4 ).

[0028] Further details regarding the design in the area of ​​the upper and central pivot ring can be found in the Figs. 6 and 7 evident.

[0029] A second embodiment is described in the Figs. 8 to 13 This is shown. It is equipped with a tensioning device 32 for fixing the open position of the parasol 2. The tensioning device 32 is designed as a tensioning element 34 with an upper end 36 and a lower end 38, the upper end 36 being hinged to the upper control ring 10. The lower end 38 is provided with a handle 40, which can be hooked onto the lower control ring 12. As can be seen from a comparison of the Figs. 12 and 13 As can be seen, the handle part 40 can be swivelled into a tensile-loaded fixing position.

[0030] The Fig. 14Figure 1 shows a third embodiment in which the upper pivot ring 10 is suspended relative to the support mast 4. For this purpose, at least three sets of struts distributed around the longitudinal axis A are required, each consisting of a support strut 8a, 8b, 8c, an associated roof strut 6a, 6b, 6c, and an associated suspension strut 14a, 14b, 14c, in order to hold the upper pivot ring 10 on the longitudinal axis A. Fig. 14 Only two of these sets of aspirations are shown.

[0031] In another embodiment, not shown in figures, the handle part 40 is not attached to the lower pivot ring 12, but to an attachment point on the support mast 4.

[0032] In yet another embodiment, not shown in the figures, the upper end 38 of the pulling element 36 is attached to the support mast 4, above the lower pivot ring 12, and the handle part 40 is attached to the lower pivot ring 12 analogously to the Figs. 12 and 13 hooked up. Reference symbol list
