Description

"Removable fixture of a goal on a sports field"

  The present invention relates to a device

  removable attachment of a goal on a sports field.

  In recent years, the use of

  goals on the sports fields was very

  widely spread because it allows for a more

  great versatility of sports fields.

  A mobile object is a frame, usually of prismatic shape, with two partially connected uprights

  high by a crossbar constituting the opening

  of the goal and two lateral, lower, horizontal parts, connected to the base of the two uprights, one

  possible rear crossbar and finally two legs in-

  clinches connecting the rear part at each end of the crossbar.

  These goals are relatively stable against reversing backwards but their shift towards

  the front on the sports fields provoked by

  Many serious, sometimes fatal, accidents, such mobile goals are no longer allowed without being firmly anchored to the ground. The present invention aims to remedy these drawbacks and proposes to create a means for releasably locking a goal without

  require the installation of

  anchored, fixed permanently or likely to damage the grass or more generally the sports field, or

  to allow the use of existing mobile goals

  not equipped with an anchoring system on the ground,

  any place on the sports field.

  For this purpose, the invention relates to a device

  detachable fastening device characterized in that it comprises: - a fixing plate intended to be fixed to a part of the mobile object,

  this plate comprising a guide tube, inclined

  born with respect to the plate to which it is attached, - an anchor rod provided with a threaded portion with a wide thread and the other end is complete

  by a support flange and a coin

  se, - a tool that removably attaches to the

  gripping piece for screwing the anchor rod

  troduced in the tube, in the soil, or unscrewed

ser

  - a protective cap which is placed on the

be.

  According to another characteristic of the invention

  the anchor rod has a smooth

  the threaded part and the gripping part, the length

  of this smooth part corresponding substantially

to the length of the guide tube.

  According to other characteristics of the

prevention:

  - the gripping piece is a hexagonal head, an em-

  preinte cruciform or hexagonal and the tool has a piece of complementary shape,

- the tool is a crank.

  The fixing device according to the invention is implemented in a very simple manner and ensures perfect blocking of the ground goal. This fixing means

  can easily be removed simply by unscrewing

  anchorages. The goal can then be transported to be stored or moved. The establishment of the device (s)

  fixing is extremely fast from

  as much as one part of each fixing device

  may be attached to the goal while traveling, either to a storage location or to a

  other location. As a result, the only operation

  each time is to place a stem of

  embedding in the tube of the fixing plate, screw

  this anchor rod into the ground and place the cape

  protective shield over the tube and the head of the

anchor rod.

  Since the stem has a collar

  killing a screw stop resting on the top

  of the tube fixed to the plate, screwing can not be

  follow until the flange is in abutment.

  This protects the anchor rod against any ex-

  cessive which would reduce the stability of the anchorage and

would complicate the unscrewing.

  The fact that the anchor rod is placed and screwed through the guide tube makes it possible to fix the screwing angle in the ground while preventing the rod from being screwed perpendicularly to the plate, which would considerably reduce its efficiency. In addition, the holding of the assembly is considerably improved and resists perfectly vibrations induced in the plate, for example when a player clings to the crossbar, shakes it or tries to

  reverse the goal. Indeed, the plate, its inclined tube

  born and the anchor rod bearing on the tube by

  its collar, is a rigid assembly.

  This holding of the connection or even the blocking

  between the anchor rod, the tube and the fixing plate

  is further increased by the fact that the end of the anchor rod which is in the tube after screwing is completed, is a smooth cylindrical surface (and not a threaded portion) which increases the

support surface rod / tube.

  Screwing is done extremely fast. Unscrewing is not only made possible but is particularly easy and fast. This means of removable attachment of the goals, which is put in place

  very quickly, also facilitates

  on the ground, the abduction of mobile goals, their

storage, etc ...

  The present invention will be described hereinafter

  in more detail with the help of an example of

  shown schematically in the drawings

nexes in which:

  - Figures 1, 2, 3 are views in

  spective of a mobile goal equipped with two, three or four

  fixing devices according to the invention.

  FIG. 4 is a schematic sectional view

  than the right of a mobile goal fixing device

according to the invention.

  FIG. 5 is a perspective view of

the plate of the device.

  FIG. 6 is a sectional view of the arrangement

  operative part. According to Figures 1, 2, 3 the invention is intended for the removable attachment of a mobile object 1. This mobile object 1 is composed, as is usual, two uprights 2, 3 connected in the upper part by a cross bar 4. Each upright 2, 3 is connected backward to a horizontal bar 5, 6 and the end

  behind the two horizontal bars is connected

  by a horizontal crossbar 7. Finally,

  the whole is stabilized by two legs 8, 9

  binding each end of the horizontal bar to the ex-

  tremité of the crossbar and receives a net.

  These tubes are generally cylindrical tubes for

security reasons.

  According to the invention, the mobile object 1 represents

  1, 2, 3 is fixed to the ground by two, three

  or four fasteners 10, 11, 12, 13, 14.

  Depending on the nature of the terrain and the conditions of use

  tion, we will use either a single fixing device

  on the lower side of the goal, ie two (in case of

soft ground, wet, etc ...).

  According to FIGS. 4, 5 and 6, the fixing device 15 consists of a fixing plate 16 intended to be pressed against the ground 17. This plate 16 is provided with a collar 18 of dimension adapted to attach to a horizontal bar 5, 6, 7 of the goal as shown in Figures 1, 2, 3. This plate could also be welded to the horizontal bar (5, 6, 7). The fixing plate 16 is provided with a guide tube 19 fixed to this plate, for example welded. This guide tube 19 is inclined relative to the horizontal direction represented by the plate, at an angle, for example 60. This tube 19 has a

  certain length. It receives an anchor rod 20

  on a part of its length a thread 21. This thread 21 is wide thread; it may be in the form of a helical ribbon terminated by a point 22. Beyond the threaded portion, the anchor rod 20 preferably comprises a smooth cylindrical portion 23. The section

  inside the tube 19 and the section of the stem of

  20 are chosen so that the anchor rod can slide in the tube without leaving too much play

  important (that is, without floating).

  At its upper end, that is to say the one not pressed into the ground, the rod 20 has a support flange 24 of sufficient width to overflow and come into the position shown in Figure 2 in abutment against the edge of the 19. Finally, it ends with a gripping piece 25. This gripping piece 25 may be positive, that is to say in relief or negative, that is to say, hollow. This gripping piece 25 is usually constituted by a head of

  hexagonal screw. It may also be a question of

Printe cruciform or hexagon.

  To screw the anchor rod 20 into the ground

  up to the position shown in FIG.

  first treats the rod freely in the tube 19 and

  with a tool 26 provided with a head 27 of complementary shape.

  to that of the gripping piece 25, we screw the

  Anchor rod 20. In the example shown, this

  til 26 is a crank. This screwing operation is extremely fast. For example, an anchor rod may have a length of the order of 60

  cm and the screwing will be done in less than a minute.

  The fitter will note the end of the screwing when the flange 25 of the anchor rod 20 will bear against the edge of the tube 19. At that moment,

  removes its screwdriver 26 and sets up a

  protective cap 28. This cap 28 is preferably

  A flexible material to prevent the tube 19 and the rod 20 are a protruding part, dangerous. It should be noted that the device for

  removable attachment 15 according to the invention may be

  against vandalism. Indeed, it is particularly difficult to tear the mobile goal; it is just as difficult to pull out a rod separately, since from the outside there is hardly any

  outlet. Only the unscrewing makes it possible to extract the rod 20.

  However, by choosing a particular form of grip, not corresponding to a hexagonal head screw but a particular form, it complicates attempts to vandalism. Plus, the extremely great ease with

  anchoring rods 20 are unscrewed,

  in no way to leave in place the modern goal

  during periods of non-use or

  night, on the grounds that the anchorage would be difficult to remove.

  worm. It is clear that the different parts and

  in particular the anchor rod can be made

  in materials that are difficult to oxidize or

  protected against oxidation by a treatment of

face.
