Description

Supports anchored in the ground

technical field

The present invention relates to support devices and more particularly to support devices which can be anchored in the ground for keeping objects fixed on the ground.

Background technique

Some support devices capable of being anchored into the ground exist in various forms. A study of the prior art has shown that there are various means of anchoring into the ground, more specifically into ground containing any particulate matter such as soil, sand, snow and the like. For ease of writing, soil is used here as an exemplary ingredient. There are a large number of support devices and they are generally distinguished by: the geometry of the support sleeve for sinking into the ground.

Among these devices we are interested in support devices consisting of tubular rods with large hollow sections, which are erected vertically when anchored into the ground. The lower end of the rod for anchoring into the ground comprises a lower opening and a blade-like thread or a pointed helical rod, the same shape as an unconstrained spring, constituting the screwing means in the ground. The upper end comprises a fastening opening in which any object such as a parasol can be fastened. By sinking the lower opening of the support device into the ground, the ground can enter into the lower end of the support tubular rod, allowing the rod to sink more easily, without the ground becoming compacted as the device spirals into the ground because the rod It has a conical closed lower end. However, when soil gets in and builds up in the tubular body of the pole, it can be difficult to get it out. If the device is used a second time, the previously formed soil column has not been discharged, a new soil column will be able to form and this new soil column will force the old soil column towards the height of the tubular pole; if the device is so After several uses, the tubular pole can be filled with soil over its entire length until the soil blocks the position of the fastening opening at the upper end of the pole, thereby preventing the fastening of objects such as parasols.

Detailed ways

Figures 1-4 illustrate a support device of the present invention for use in a floor S containing a particulate content and for supporting objects not part of the invention, such as sunshade umbrellas secured to the floor.

This support device 10 comprises a rod with a hollow tubular portion defining two ends: a lower end corresponding to the end that can be anchored into the ground, and an upper end opposite the lower end.

A lower opening 14 is located at the lower end of the rod 12 . An upper opening 16 is located at the upper end of the rod 12 .

A pointed threaded rod 22 is fixedly connected to the lower part of the rod 12, as shown for example in FIG. 1 . This threaded rod 22 represents the screwing means of the device 10 . The helical rod 22 is used to assist the user of the device 10 in anchoring the device 10 into the ground S. As shown in FIG. The helical rod 22 acts on the thread of the screw. The converging lower part 22a of the helical rod 22 goes beyond the lower end of the rod 12 towards the bottom, so that it is easy to anchor the device 10 in the ground S, and the part of the rod 12 surrounded by the helical rod 22 can be rotated further. Easy access to ground s. Since the body of the rod 12 itself is cylindrical and hollow, the effective area against subsidence is very small.

The rod 12 has a central hole 18 on its side, which is located between and spaced from the openings 14 and 17 .

In addition, the rod 12 is provided with a deflection device 24 in the form of an elliptical metal plate. The deflection device 24 is in the shape of an elliptical metal plate. Paste and. The deflection device 24 is arranged obliquely inside the rod 12 such that the deflection device 24 faces the hole 18 obliquely. The tallest part of the deflection means is aligned with the upper part of the contour of the hole 18 .

An elongated tightening arm 20 is pivotally connected to the rod 12 by one of its ends. The connection point between the arm 20 and the rod 12 is between the hole 18 and the upper opening 16, for example directly above the hole 18 as shown. This arm 20 can swing between two defined positions: a folded position and an unfolded working position in which the arm 20 is parallel to the rod 12 and the free end of the arm 20 faces the top of the rod 12, As shown in FIG. 1 ; in the deployed working position, the arm 20 is perpendicular to the rod 12 , as shown in FIG. 2 . This arm makes it easier to rotate the device 10 about its central axis of symmetry. The arm 20 is thus a lever arm that readily applies a rotational torque to the rod 12, thereby facilitating the screwing of the device 10 into the ground S.

On the rod 12 are two fastening screws 26 and 27 . The two screws 26 and 27 lie opposite each other in diametrically opposite positions on the rod 12 . The screws 26 and 27 are used to hold in place by fastening an object inserted through the opening 16 into the hollow of the pole 12 , for example inserting the lower end of a pole of a parasol into the hollow of the pole 12 .

The support device 10 works as follows: the arm 20 first pivots in the working position. Then, the lower point of the helical rod 22 is pressed towards the ground S. The device 10 is then repeatedly rotated about its central axis of symmetry. Each revolution made by the device 10 causes the threaded rod 22 and the rod 12 to sink into the ground S, the threaded rod acting as a thread. The support device 10 can be sunk to the desired depth, however the intermediate hole 18 must be above the ground S at all times.

As the device sinks into the ground S, ground S containing granular material will enter the rod 12 through the lower opening 14 . A column of soil thus gradually forms inside the rod 12 . Depending on the material composition of the ground S, this column of soil is more or less difficult to remove. The ground S containing the material is not discharged, but enters the inside of the pole 12, and the center of gravity of the device 10 is at a lower position, thereby increasing the firmness of the device 10 fixed on the soil S.

Once the device 10 is sunk into the soil S at the desired depth, the arms 20 are swung towards their overlapping position. Objects with fixed posts, such as parasols, can then be temporarily or permanently fixed to the support device. The explanation will continue with the embodiment of a sunshade as an object fixed above the ground, regardless of its extension, any object can be fixed on the pole 12 which can be used with the device 10 .

The lower end of the fixed leg of the object is inserted into the rod 12 through the upper opening 17 and held in place by means of fastening screws 26 and 27 which, once tightened, exert sufficient pressure to tighten the fixed leg of the object. Hold it tightly in place.

In order to stow the device 10, the steps described above need to be performed in reverse order.

When using the device 10 as described above, the column of soil formed may be at least parallel to the interior of the hollow body of the rod 12 . If the device 10 is subsequently pulled out and screwed back into the ground S, additional soil will be inserted into the lower end 14 of the rod 12 . The column of soil thus rises higher and higher in the pole 12 until it meets the height of the middle hole 18 . The deflection means 24 prevents the flow of particulate material from the ground surface S from rising past the central hole 18 and thus prevents blocking the upper opening 16 allowing objects to be inserted into the opening 16 . The column of soil is in fact gradually deflected by the deflection device 24 towards the hole 18 and out of the rod 12 through the hole 18 , while new soil enters through the lower end 14 .

The helical rod 22 can be replaced by another anchoring device. According to one embodiment of the invention, the helical rod 22 is welded on the rod 12 . In addition, however, it can also be decided not to include the helical rod 22 , the device being sunk into the ground S and then achieved by hammering or malleting on the upper end of the rod.

According to an embodiment of the invention, the arm 20 can not comprise the above-mentioned shape. A detachable arm may be provided, the end of which can be inserted into a socket on the side of the pole when it is desired to screw the device 10 into the ground S. In addition, it is also possible to provide a support device 10 without a tightening arm.

Said fastening screws 26 and 27 can be replaced by other fastening means. For example, a button can also be provided in the upper part of the rod 12 . The tubular rod of the object to be supported comprises holes in its lower part, one of which is able to accommodate a button located on the rod 12, thus holding the object in place.

Any other type of modification of the invention is also conceivable without going beyond the scope of the appended claims.
