Description

stand for items such as parasols

The invention relates to a stand for objects such as parasols, signs, billboards or clothes hangers, having an upper part for supporting a pole of the object and a lower part facing the ground.

Stands of this type can be made of different materials, an important prerequisite being that the weight should be dimensioned according to the required stability. Some stands are heavy, for example made of concrete, and are difficult to transport. There are also stands that can be filled with water or sand, making them easy to transport when emptied. A major disadvantage of all these stands is that when they are not in use, or are left standing, there is a risk of accidents and injuries as pedestrians may trip or run into them; It must be transported back to the place of use when needed, but this is laborious for heavy stands, or impractical or laborious for emptyable stands. It is also known to insert or enclose in the ground a tube into which the rod of the article is inserted. However, the diameter of this tube must be larger than the diameter of the rod, so it is not perfect.

The object of the present invention is to provide such a stand which can be easily mounted and dismantled with high stability and is light in weight.

According to the invention, a stand of this type which achieves the above-mentioned object is characterized in that there is a central connection element arranged in the lower region, which can be positively connected to a fixing element firmly anchored in the ground (underground) .

Because the stand of the present invention is firmly anchored to the ground, its stability is not obtained through a large weight, so it can be constructed into a relatively light structure. After the stand has been detached from its anchor in the ground, no interfering parts remain because the anchor can be fully sunk into the ground.

Within the scope of the invention, it is preferred that the central connection part is designed as a screw and the fastening part as a dowel. However, other connection methods can also be used, such as a threaded quick connection, a screw-in (bayonet) connection or a snap-in connection.

Further preferred embodiments of the invention are the subject matter of the remaining subclaims.

Preferred embodiments of the invention are described below with the aid of the drawings. in:

The view of the stand in Fig. 2 Fig. 1 in assembled state,

Fig. 3 is an exploded view of a second embodiment of the stand of the present invention,

The view of the stand in Fig. 4 Fig. 3 in assembled state,

Figure 5 is a top view of a mounting device,

FIG. 6 is a sectional view of the above-mentioned mounting device along the line VI-VI in FIG. 5 .

In Fig. 1 is shown a first embodiment of a stand according to the invention, which basically comprises a tubular upper part 1 and a disc-shaped lower part 2, which are welded together. The lower part can also be designed into other shapes besides the disc shape, such as a star-shaped foot or a support, which is not positioned at the bottom of the pipe 1 but is fixed at a higher position and protrudes obliquely downward.

In the region of the lower part 2 , a screw 3 is fastened inside the tube 1 , as shown in FIG. 2 . For fixing the screw 3 in the pipe 1, a bearing part 4 is provided which comprises a receiving part 5 and a fixing part 6. The receiving part 5 is fixed to the bottom end of the tube 1, for example by welding or gluing. The screw 3 passes through the receptacle 5 from above, wherein the screw head 8 is fixedly seated in a recess 9 of the receptacle 5 . In order to prevent axial movement of the bolt 3 , the fixing part 6 is screwed together with the receiving part 5 by means of a bolt 7 . Bonding is also possible. Furthermore, the fastening part 6 has a centering opening 10 in its upper part.

A pole of an object such as a parasol, a sign, a billboard or a coat hanger can be inserted into the tube 1 from above and it can be centered in the centering opening 10 if the pole has a pointed end at the bottom end. For fixing the rod in the tube 1 , for example, a known clamping screw is used, by means of which the inserted rod can be centered and locked by turning. The rod can also be secured by one or more bolts screwed horizontally through the pipe wall.

The connection to the ground is achieved by, for example, inserting a dowel 11 made of high-quality steel or aluminum into a prefabricated hole in, for example, asphalt or concrete ground, and bonding it in the hole so that it The upper edge 12 is flush with the surface 14 or slightly lower than the surface 14. The stand can then be screwed by means of its bolts 3 into the fixing part 11 until the plate 2 rests firmly on the ground.

Depending on the loads expected to be carried on the stand, the diameter of the plate 2 or the radial distance from the stand foot forming the lower part to the central connection formed by the bolt 3 can be of various sizes.

By means of the invention, it is possible to provide fixings in the form of dowels 11 etc. where it is expected that the object must be erected repeatedly, which do not interfere at all when not in use. If desired, the stand of the present invention can be quickly and stably erected in these prepared areas.

An embodiment of the stand according to the invention is shown in FIGS. 3 and 4 , which essentially corresponds to the embodiment shown in FIGS. 1 and 2 . The main difference lies in the construction of the lower part in the form of a base plate 2' and the structure of the fastening means of the central connection in the form of bolts 3'. In the embodiment of the stand shown in FIGS. 3 and 4, a simplified embodiment is involved, wherein the bolt 3' is screwed into a threaded hole 13 in the base plate 2', thus saving the stand of the invention. cost of production or manufacture of racks. The bolts can be secured against rotation, eg by bonding.

The anchoring of the stand of the present invention can be further simplified by replacing the traditional bolts 3, 3' which need to be screwed into the dowels 11, 11', and adopting other connection methods, such as threaded quick connections , plug-in rotary connection or snap-in rotary connection.

Also shown in FIGS. 1 to 4 is an elastic layer 15 on the underside of the plate 2 , which can be, for example, a rubber plate and is fixedly bonded to the base plate 2 . The rubber plate 15 preferably rests on the bolts 3 , 3 ′ and is used to compensate for ground irregularities and to prevent friction of the underside of the soleplate 2 against the ground surface 14 , such as tiles or paving stones.

The fixings 11, 11', eg threaded dowels, must be firmly anchored in the ground 14 (underground). This can be done, for example, by applying adhesive or grout to a hole in the ground. It is important here that the dowels 11 , 11 ′ are inserted perpendicularly to the ground surface 14 or to the underside of the base plate 2 .

This can be achieved on the one hand in that the dowels 11, 11' are screwed onto the bolts 3 of the stand, the adhesive or grout is introduced into the holes in the ground and the dowels 11, 11' are then connected to the stand 1 Press together into the hole. In this embodiment, the rubber plate 15 is very effective, because the dowel 11 can be screwed onto the bolt 3 in such a way that the dowels 11, 11' seal against the rubber plate 15, preventing adhesive or grout from Penetration between the dowels 11, 11' and the bolt 3 would otherwise make the connection difficult or impossible to loosen.

Alternatively, in order to insert the dowels 11, 11' into the ground, a mounting device according to FIGS. out. A supporting ring 19 is fastened to the free end of the brace 18 .

The dowels 11 , 11 ′ are mounted by means of the mounting device in such a way that the dowels 11 , 11 ′ are first screwed onto the threaded pin 16 sufficiently far. Then fill enough suitable material (such as adhesive or grout) in the hole on the ground, and by means of installation device dowel 11,11 ' is pressed deeply enough in the hole, until supporting device 17 is fully attached. Lean on the ground. Excess adhesive on the mounting device can be easily removed, since the adhesive points can be reached via the braces 18 . Once the dowels 11, 11' are sufficiently firmly fixed in the ground, the mounting means can be unscrewed from the dowels 11, 11'.

In summary, an embodiment of the present invention is as follows:

A stand for objects such as parasols, signs, billboards or coat hangers, having an upper part 1 for supporting a pole of the object and a lower part 2, 2' facing the ground. In order to anchor the stand on the ground, a central connecting element 3, 3' is provided, for example a bolt, which is arranged in the region of the lower part 2, 2' and can be connected with a fixing element 11 firmly anchored in the ground , 11', for example a dowel, are positively connected.
