Definitions

• the present invention relates to an expandable stand.
• Feet which are often referred to as umbrella stands, can be used, for example, to hold parasols or small flagpoles from advertising flags.
• Feet are known that are heavy and take up a lot of space, so that transport is difficult.
• Such mobile feet that can be brought into a transport state in which they are less voluminous.
• Such mobile feet usually have fold-out feet or ground spikes.
• the models with the fold-out feet are designed to be weighted down with separately transported concrete slabs, while the models with the fold-out ground spikes are laborious to fix in the ground.
• the object of the invention is to provide a stand which overcomes the disadvantages known from the prior art.
• the object of the invention can thus be seen, inter alia, in providing a stand that is easy to transport and that can be used on any type of surface.
• a stand comprising an expandable central chamber which, in the expanded state, has a sleeve with a forms an upwardly open end for receiving a rod, a base element and at least one expandable connecting chamber which connects the central chamber with the base element.
• the stand is in the non-use state, i.e. in the non-expanded state, very compact and light.
• the base In the state of use, i.e. in the expanded state, the base can accommodate a rod, such as an umbrella base, and hold it upright.
• the floor element can be weighted down, for example, with water, sand or other weight elements that are available at the installation site.
• the chambers of the stand are expandable. This means that the volume of the chambers can be changed from a small volume, in the non-expanded state, to a larger volume, in the expanded state.
• the expandable chambers are filled or partially filled with an expandable filler such as a foam, the filler being compressed in the non-expanded state and expanded in the expanded state.
• the chamber can be made air-permeable or air-impermeable.
• An air-permeable chamber is understood to mean a chamber whose envelope is air-permeable.
• An air-impermeable chamber is understood to mean a chamber the envelope of which is air-impermeable.
• mixed forms are also provided in which one or more chambers with filler are combined with one or more chambers without filler in a stand.
• the central chamber and / or the at least one connecting chamber is preferably an airtight, ie air-impermeable, chamber.
• one connecting chamber can thus preferably be designed as an airtight chamber; particularly preferably, all connecting chambers are designed as airtight chambers.
• the central chamber and / or the at least one connecting chamber can be expanded by inflation. If more than one connection chamber is present, one, several or all connection chambers can thus be designed to be inflatable.
• the expandable stand preferably does not comprise any rigid material; the expandable stand is particularly preferably made of plastic, in particular PVC.
• the central chamber In the expanded state, the central chamber forms a sleeve with an end that is open at the top for receiving a rod. In the expanded state, the central chamber thus forms an elongated envelope with a vertical longitudinal axis, into the end of which a rod, stick, tube or other rod-like object can be inserted.
• the upwardly open end of the central chamber in the expanded state preferably forms an opening which, in plan view, forms a slot, a circle, an oval or a polygon, particularly preferably a triangle, square, pentagon or hexagon.
• the sides of the polygon preferably form indentations, preferably semicircular indentations, in the direction of the center of the opening. Due to these indentations, bars with various cross-sectional shapes and sizes can be held securely.
• the base has at least one connecting chamber that connects the central chamber to the floor element.
• the inflatable stand comprises at least two, preferably at least three, expandable connecting chambers that each connect the central chamber to the floor element.

• the connecting chambers are preferably arranged distributed circumferentially around the central chamber.
• the connecting chambers are particularly preferably arranged distributed regularly around the circumference of the central chamber.
• the effect of the connecting chambers is that, in the expanded state, the central chamber cannot tilt in the direction that is approximately opposite the connecting chamber. It is therefore particularly advantageous if the connecting chambers are distributed circumferentially around the central chamber, so that tilting of the central chamber in any direction can be prevented.
• the connecting chambers can thus form transverse struts which connect the central chamber to the floor element. If only one or only two connection chambers are used, however, it is advantageous if the one or two connection chambers are not designed as thin transverse struts, but rather as wide elements, so that the central chamber is largely circumferentially surrounded by one or two connection chambers , and tilting of the central chamber can be prevented.
• the connecting chambers can also be designed as partition walls, such a partition wall preferably having the shape of a triangle, which extends with a first side to the floor element, preferably to the floor mat, and with a second side to the central sleeve. Because of these partitions, the floor element can be loaded separately from one another with different weight elements.
• the expandable central chamber and the at least one expandable connecting chamber in the expanded state form an angle in the range from 20 ° to 60 °, preferably in the range from 30 ° to 50 °, to one another.
• Such an embodiment offers one good stability with a compact shape of the base in the expanded state.
• the at least one expandable connecting chamber in the expanded state is at least half as long as the expandable central chamber in the expanded state.
• the base element is connected to the at least one connecting chamber and can be weighted with one or more weight elements.
• Particularly suitable weight elements are sand or water.
• the connecting chambers are preferably arranged at a distance from one another, so that the weight elements can be applied to the base element between two adjacent connecting chambers. If only one connection chamber is used, it preferably has an opening for attaching a weight element to the base element.
• the floor element comprises a floor mat, in particular a floor film.
• the end of the central chamber opposite the open end is connected to the floor element, preferably to the floor mat.
• the expandable central chamber is preferably closed at the bottom by the floor element, preferably by the floor mat.

• the bottom chamber can be circular in plan view, but the bottom chamber can also be polygonal, preferably a rectangle, in plan view.
• the base chamber In the expanded state, the base chamber preferably forms a base ring which is circular in plan view and whose axis of rotation extends axially to the longitudinal axis of the central chamber.
• the floor mat and the floor chamber are connected to one another.
• the floor mat preferably covers the entire area which is delimited circumferentially by the floor chamber.
• the bottom chamber preferably forms the outer end of the bottom element in plan view. When in use, the floor chamber preferably rests directly on the ground.
• the bottom chamber can be filled or unfilled with filler material.
• one, several or all of the chambers selected from the group consisting of the central chamber (2), connecting chambers (3, 4, 5) and bottom chamber (8) form airtight chambers.
• one, several or all of the chambers selected from the group consisting of the central chamber (2), connecting chambers (3, 4, 5) and bottom chamber (8) can be expanded by inflation.
