Description
[0042] The invention is subsequently explained again with reference to the figures.
[0043] FIG. 1 shows an exemplary embodiment of a base according to the invention in a perspective view.
[0044] FIG. 2 shows an exemplary embodiment of a base according to the invention in a top view.
[0045] FIG. 3 shows an exemplary embodiment of a base according to the invention in a perspective view from below.
[0046] FIG. 4 shows a sectional depiction of an exemplary embodiment of a base according to the invention.
[0047] FIG. 5 shows a sectional depiction of an exemplary embodiment of a base according to the invention.
[0048] FIG. 6 shows an exemplary embodiment of a central chamber of a base according to the invention in a top view.
[0049] FIG. 1 shows an exemplary embodiment of a base 1 according to the invention in a perspective view. The base comprises an expanded central chamber 2 with an opening 9 arranged above for receiving an umbrella rod, which may be inserted into central chamber 2 in the longitudinal direction, so that central chamber 2 surrounds the rod. Central chamber 2 is held in the vertical alignment by expanded connecting chambers 3, 4, 5 designed as transverse struts. Connecting chambers 3, 4, 5 extend from the upper end of central chamber 2 to an expanded base chamber 8, which surrounds the lower end of central chamber 2 as a circular base ring. Base chamber 3 represents the lateral delimitation of a base element 6, which additionally has a floor mat 7, which covers the area delimited by base chamber 8. Floor mat 7 is connected water-tight to base chamber 8, so that the space, which is delimited laterally by base chamber 8 and from below by floor mat 7 may be filled with water. The water acts as a weight element, so that base chamber 8 and thus connecting chambers 3, 4, 5 remain in the depicted alignment—even with a rod inserted into central chamber 2—and may hold the inserted rod upright. Central chamber 2, connecting chambers 3, 4, 5, and base chamber 8 are configured as inflatable chambers, wherein the valve or the valves for inflating the chambers are not depicted.
[0050] FIG. 2 shows an exemplary embodiment of a base 1 according to the invention in an expanded state in a top view. Base 1 comprises a central chamber 2, which is connected to three connecting chambers 3, 4, 5, wherein the lower ends of connecting chambers 3, 4, 5 are respectively connected to base chamber 8. Connecting chambers 3, 4, 5, are arranged distributed regularly circumferentially about central chamber 2, and extend radially from central chamber 2 to base chamber 8, when viewed from above. Central chamber 2 forms a sleeve, into which a rod may be inserted through opening 9. Base element 6 comprises, in addition to base chamber 8, a floor mat 7, which connects the lower end of the central chamber completely to base chamber 8.
[0051] FIG. 3 shows an exemplary embodiment of a base 1 according to the invention in the expanded state in a perspective view from below. Base 1 comprises a base element 6 with a floor mat 7, which represents the lower end of base element 6, and at whose outer edge a base chamber 8 is arranged. Base 1 comprises a central chamber 2, whose lower end is sealed, wherein floor mat 7 is connected water-tight to central chamber 2. According to the invention, the lower end of central chamber 2 may also be sealed by floor mat 7.
[0052] FIG. 4 shows a sectional depiction of an exemplary embodiment of a base 1 according to the invention in the inflated state. A central chamber 2 is arranged vertically and forms a sleeve, through whose opening 9 a rod may be inserted and pushed in up to floor mat 7. Central chamber 2 is connected to connecting chambers 3, 4, 5, which extend form central chamber 2 up to base chamber 8. Base chamber 8 is connected to floor mat 7 and surrounds the same along the circumference. Base chamber 8 comprises a valve 10, via which base chamber 8, and the additional inflatable chambers, may be inflated, or from which air may be discharged.
[0053] FIG. 5 shows a sectional depiction of an exemplary embodiment of a base 1 according to the invention in the inflated state. Base element 6 comprises a circumferential base chamber 8, a floor mat 7 arranged below, and a cover 12 arranged above floor mat 7. In this way, a cavity is formed between floor mat 7, base chamber 8, and cover 12, which may be filled or emptied via valves 11 and 13.
[0054] FIG. 6 shows an exemplary embodiment of a central chamber of a base 1 according to the invention in a top view. Central chamber 2 has a quadratic opening with semicircular indentations in the direction of the central opening. Such an opening enables the fixing of rods with diverse cross-sectional shapes and diverse cross-sectional sizes.
