Abstract

The base consists of a tube (1) whose upper end includes a collar or plate (2) with a downwardly-directed flange (3) around its periphery. The plate has a hole corresponding in size and position to the hollow interior of the tube. At the lower end of the tube are attached three fins (5) at regular angular spacing from each other. The fins project beyond the body of the tube and are triangular in shape to define a tapering point structure. The tube is forced into a ground surface by direct hammer impact or by impact on a cooperating intermediate driver which fits into the hole in the collar.

Description

The present invention relates to a metal base with fins with its post / base fixing system and also to its special driving device, the assembly intended, once the base inserted into the ground, to support all types of posts. mesh fence and welded mesh existing on the market, sign post and all types of equipment using posts.

The existing bases on the market represent various disadvantages.

- Generally studied and sold with a post concept.

- The incorrect placement technique, often by manual threshing with mass, implying a considerable effort for the user as well as a random planting precision.

- Inability to set up on difficult terrain such as asphalt, for example.

- Post base fixing device requiring different parts or none in certain cases, giving a result reducing the rigidity of the post as well as a blocking installation requiring several tools.

- Often produced in heavy technique, resulting from a high price.

- Poor resistance to tearing and twisting due to their short lengths and the concept of the fins - Poor aesthetics in terms of finish, this often protruding from the ground for the post base fixing device.

The purpose of this invention is to provide installers with rapid installation comfort on all types of terrain, eliminating concrete seals and the creation of holes, which can intervene in areas difficult to access and giving optimum mechanical resistance, a quality realization and to be able to adapt on base all types of posts.

The present invention is represented on the one hand at the base with its base / pole fixing system and on the other hand has its driving device.

Figures 1,2,3 show the base seen respectively from the front, above and below.

FIG. 4 represents the driving device from the front.

Figure 5 shows the front mounting system base / pole.

Figure 6 shows from above the base / pole fixing system.

The base is represented by a tube of different diameters depending on the dimensions of the posts used.

This tube (1) is made of steel of sufficient thickness to receive significant shocks during pneumatic or electric driving.

On the upper part of this tube is welded a square collar (2) with flange (3) pierced in its center (4) to the diameter of the tube.

On the lower part of the tube three fins (5) positioned at equal distances are welded around it and cut into a point
These fins are welded together to the level of the tube, then to the tube.

By way of nonlimiting example, base will have dimensions of the order of 600 mm in total length, square collar of 120 x 120 mm with 25 mm flange, tube 8 60 mm, fins of 250 mm in length, of width 80 mm ending in point. (see drawings).

The base may have different lengths depending on the nature of the ground (longer for topsoil) and different diameters depending on the posts to be installed.

The base / post fixing device is represented by a triangular metal wedge (6) which is positioned between the base and the post by wedging with a simple manual hammer blow.

The metal corner is positioned either perpendicular to the post for T-iron or parallel for round tube.

By way of nonlimiting example, the corner will have dimensions of the order of 150 mm in length, 50 mm in width ending in a point. (see drawings).

The driving device is represented by a driving head (7) in solid steel of cylindrical shape with a tip (8) for pneumatic or electric hammer.

On the lower part, a stud (9) is machined so that it can be fitted into the tube (1) of the base until it stops against the collar (2).

On the upper part a hole (10) is machined to be able to fit the end piece (8) of the pneumatic or electric hammer.

 By way of nonlimiting example, the driving head (7) will have dimensions of the order of 250 mm in total length, with a diameter of 100 mm, the stud (8) of 60 mm in length and in diameter 50 mm> the hole (1 0) 100 mm deep and 50 mm in diameter.

The hammer tip (8), in a standard hexagon shape, adaptable to any conventional air and electric hammer, will be cut flat to remove the tip of the pick so as not to lose energy during threshing and do not not damage the bottom of the hole (1 0) in the driving head.

The implementation is simple and fast, once the bases on the ground, it is enough to fit the driving head (7) in the base then the end piece (8) of the hammer in the hole (I 0) with the hammer.

Straighten everything to the desired point and activate the operation of the air or electric compressor.

The driving head (7) through the tip (8) of the hammer, strikes on the flange (2) and on the top of the tube (1).

Pressed down to -5 cm from the ground level, it only takes a maximum of 2 minutes to set it up.

The post must be positioned in the base then be clamped at the desired level with the metal corner (6) using a hand hammer.

The result offers greater resistance to tearing and twisting than a concrete seal.

Intervention on all types of terrain and whatever the access.

The base and the corner are treated anti-corrosion by bi-chromated zinc plating (can be untreated) or hot galvanized.

The very concept of the base is calculated to withstand significant shocks during threshing by the thickness of the steel and its welds, no deformation is possible.

If the base encounters a more or less important pebble (except rock), this one due to its shape pushes the material and by sliding makes its place in the ground.

Level penetration is readjusted during threshing.

The base once planted, the fins representing half the length of the base and 2 times wider than the tube allows perfect guidance and the impossibility of tearing it off.

The flange, with its edges, makes it possible to give a resistance at high point by an attachment of the materials under it.
