f JUL I 5 5975 8 9 SHEET 9 5616. Fla? PROCESS FOR POSITIONING VARIOUS POLES AND THE LIKE AND DEVICE FOR EMBODYING THE SAME Positioning poles or posts into the ground for making fences and like constructions has, up to now, necessitated manual handling which is time consuming because a rather broad hole is made in the earth, the pole is introduced into the hole and then the pole is embedded into earth or concrete. Moreover, the poles or posts thus positioned can not be dismantled.
Through the invention all the manual handling is avoided and the poles, although being very strongly fastened to the ground, are dismountable.
According to a first aspect of the invention, the process for placing into the ground sleeves, each intended to receive a pole or like member comprises the steps of preparing a tubular sleeve, of slipping said sleeve onto a penetrating pin up to a retaining stop, of simulta neously driving the sleeve and the pin into the ground with said pin protruding beneath said sleeve, of applying said stop on the top of the sleeve during the penetration, of removing the pin from the sleeve and from the ground while maintaining the stop against the top of said sleeve, of driving off said stop and of inserting a pole into said sleeve, thus forming a housing for the base of the pole.
The invention relates also to a device for embodying the above process.
According to this second aspect of the invention, the device for placing into the ground sleeves, each intended to receive a pole or like member, comprises: a sleeve made of plastic material, a penetration pin engaged into the sleeve and protruding beneath said sleeve; means to simultaneously driving in the pin and the sleeve, means to retain the sleeve during the removal of the pin, and a pole, shaped at the base thereof according to the cross sectional form of the sleeve engaged in the ground.
For a better understanding of the present invention, and to show how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which:

FIG. 17 is a diagrammatic sectional view showing another development of the invention.
FIGS. 18 and 19 are sectional views showing another development of the invention.
FIG. 20 is a sectional view showing an additional characteristic of the invention.
Referring now to FIG. 1, an anchor-sleeve, designated by 1, is constituted of a tube, preferably made of synthetic resin, (for example of polyethylene, polyvinyl chloride or the like). The sleeve is driven into the ground with a portion la of the sleeve advantageously protruding above the surface 2 of the ground to prevent soil from penetrating therein when a pole is not yet placed or when it is removed.
Advantageously, the sleeve 1 is provided on the outer wall thereof, with protuberances 3 which can be constituted in various ways, for example as shown in 30 they can be made of slightly folded back barbs cut from the sleeve 1 and protruding in a direction for which they tend to prevent the removal of sleeve 1. The protuberances can also be constituted in the shape of sharp teeth as shown in 3 by providing a protrusion of material on the outer wall of the sleeve.
The pole 4, designed to be engaged inside the anchor-sleeve l, is constituted of a tubular element which preferably is made of synthetic resin, more preferably of thermoplastic synthetic resin in the form of foam or sponge. The pole is covered, at least on the outer wall thereof, with a dense skin in order to obtain, as shown in FIG. 1 of the drawing, a dense and rigid envelope 5 enveloping the foam body 6. To obtain such a pole, the synthetic resin previously provided with a foaming agent is injected into a cooled forming nozzle or into a cooled mobile mold. The nozzle or mold being insidely provided with a mandrel forming the inner wall 7 of the pole. Thus, a continuous tube is made with the forming nozzle or the mobile mould forming the skin or envelope 5 since said nozzle, or mold, is cooled to prevent the development of foam by the resin immediately in contact with the cold wall, while body 6 develops in foam between the immediately cooled skin 5 and the mandrel forming the inner wall 7. Said continuously made tube is then cut into sections, as required, to constitute the poles.
Finally, when a pole is introduced into the anchorsleeve 1, the pole is closed at its upper portion by a cover 8 also made of synthetic resin through molding by injection or another similar process.
Constructing the pole 4, as hereinabove described, gives the outer wall 5 an appearance of wood. The poles are made so as not to be an aesthetic nuisance when they are placed into the ground.
The body 6 of the pole being made of foamed resin, it is possible to fix nails therein or to screw some screws. Then as shown in FIG. 2, it is possible to place wires 9 connecting the various poles. In this respect, FIG. 1 shows a wire staple 10 wherein one of the wires 9 is passed.
The anchor-sleeve l of FIG. I can also be made by extrusion in a forming machine placed at the outlet of an extruding machine and also comprising a mobile mold similar to the mold utilized for forming the tube constituting the poles, that is substantially comprising a mobile mold which can be constituted by cooperating caterpillars forming between them a molding cavity where the formed protuberances 3 or 3a are.
To place the anchor-sleeves 1 into the ground, a pin 11, (FIG. 3) longer than the sleeve 1, is provided at its lower portion with an ogive l2 facilitating its penetration into the ground. The pin 11 forms at the upper portion of the ogive 12 a small annular groove 13, of a small depth and in which penetrates the folded back end of the sleeve 1. Above the sleeve 1, the pin 11 is provided with an extraction component 14 bearing beneath a shoulder 15 formed by the upper portion of the As it appears from the above disclosure, when hitting or applying a pressure on the top of the pin previously equipped with a sleeve 1, said pin and said sleeve progressively penetrate into the ground, and the soil cannot penetrate between the pin and the sleeve due to the folded back portion 1b placed in the groove 13.
When the penetration is sufficient, the pin 11 is removed while maintaining the extraction component 14 against the top of the sleeve.
To facilitate the extraction, it is possible to design longitudinal grooves or ribs on the wall of the portion of the pin penetrating into the sleeve, said longitudinal grooves causing the pin to bear on the inner wall of the sleeve only by a very small surface. It is also possible that these grooves or ribs the same being not shown in the drawing be spiral-shaped, thus by rotating the pin, its removal is made much easier.
FIG. 4 shows a variant in the realization of the anchor-sleeve, wherein said sleeve, designated by 1,, forms at the lower portion thereof, an inner shoulder 16 having an outer wall 160 which is substantially in the shape of a truncated cone, or of an arc of circle, or of parabola. In addition, the upper portion of the sleeve forms a collar 17 designed to bear on the surface 2 of the ground.
In this realization, the pin 1 provided to drive the sleeve into the ground comprises an added ogive 12, forming in front of the shoulder 16 a slightly smaller portion 12 preven ing the soil to penetrate between the pin and the inner wall of the sleeve. In this embodiment it is to be noted that stresses due to the driving-in are applied by the pin directly on the top of the shoulder 16. This is on the lowest portion of the sleeve and also the portion having a greater strength.
Samely as for the annular groove 13 shown in FIG. 3, the portion 12 has a very small depth in order that the further removal of ogive 12 does not present any difficulty.
The ogive 12 in FIG. 3 and ogive 12 in FIG. 4 can be made, for example, of plastic material and be only placed to be removable from the pin 11 whereby these ogives remain in the ground. It is also possible that said ogive be directly formed from the shoulder 16 and then the pin bears only on the top of the ogive being thus an integral portion of the anchor-sleeve 1.
FIG. 5 shows a variant wherein the pole 4 laterally has longitudinal wings 18 containing apertures 19. The apertures 19 are provided for placing of the wires 9 in FIG. 2. The tubular shape of the poles is provided for placing in the inner channel they delimit, a reinforcement web 20 which can be constituted by a metal or concrete tube of any shape. The shoulder 16 of the anchor-sleeve 1, is then particularly advantageous since it centers the reinforcement web 20 upon its position- FIGS. 6 and 60 show two variations of the construction of the tubular pole, wherein said poles have an outer annular envelope 5 and an inner annular envelope; the two said envelopesbeing connected by struts 20 radially placed in FIG. 6, or by struts 21 forming successive triangles as shown in FIG. 6a.
In FIG. 7, reference 101 designates the rear portion of a tractor and 102 the lifting mechanism usually designed at the rear portion of said tractor, said lifting mechanism supporting a frame 103 advantageously provided with a trailer 104 comprising skids 105.
The group including the frame 103 and the trailer 104 is preferably setoff laterally to the tractor or placed in the vicinity of its longitudinal axis, between the wheels, depending on the path the tractor will follow to place into the ground the sleeves 106 designed to receive the poles 4.
In FIG. 7, the frame 103 supports a driving in jack 107, constituted by a double-effect jack advantageously provided with a vibrating device, and an extruding jack 108 called.
The lower portion of the piston 11] of extraction jack 108 is provided with an extraction component constituted by a ring or a fork 112 passing around the piston 109 of the jack 107.
In front of the jacks 107, 108 and as shown in FIG. 8 the slide-guides 110a, 1 10b are replaced by swivelling flaps 113, 114 usually kept in line with said slide-guides by sets of springs 115, 115a and 116, 116a. The flaps 113, 114 comprise retaining stops 117 and respectively 117a, against which bears a collar 106' similar to the collar 17 of FIG. 4 and provided on each of the sleeves having to be driven into the ground. FIG. 8 shows, for the sleeve 106 that the collar 106' is retained by the stops 117, 117a.
The swivelling flaps 113, 114 are connected, at the ends thereof directed towards the sliding-guides 1100, 110b, to swivelling arms 118, and 118a, respectively the same being placed in the position shown when the flaps 113, 114 are in the horizontal position.
The above described device operating as follows: To drive in a sleeve, the jacks 107 and 108 being in the position shown in FIG. 8, through an external control, the piston 109 starts to penetrate into the sleeve 106, and the piston 111 begins to move down so that the fork 112 begins to bear on the collar 106'. While this downward motion continues, the fork 112 bearing on the collar 106' makes the flaps 113, 114 swivel downwards until collar 106' of the flaps is released. At the same moment the arms 118, 118a swivel at the same time and bear on collar 106'a of sleeve 106a to hold said sleeve.
The piston 109 passes entirely through the sleeve 106, The ogive shaped end portion 109a protrudes beneath said sleeve 106, and digs the ground. The fork 1 12 going down at the same time and at the same speed as the piston 109 of the driving-in jack 107, the sleeve 106, is also moved down and is introduced into the ground when the collar 106' comes in contact with the surface of the ground as shown in FIG. 7. The piston 109 is then raised while the piston 11 l of the jack 108 is kept motionless as shown in FIG. 7, thus the fork 112 connected to the piston 111 prevents extraction of the sleeve 106, while the piston 109 is removed. Finally the piston 111 is then taken up, the fork 112 lifting the flaps 113, 114 together with the arms 118, 118a said fork is when coming back to the position represented in FIG. 8. During lifting of the flaps, the sleeve 106a cannot go forward since the end of said flaps constitutes a stop for the collar 106'a. Finally the flaps 113, 114 are taken back to the horizontal position thereof by the springs 115, 115a and 116, 116a, thus providing the sleeve 106a to slide up to the position previously occupied by the sleeve 106, and a new driving-in process can take place after having displaced the trailer 104.
It is to be noticed that the various operations as above described can easily be automatically controlled by a simple programming unit, the same being advantageously placed on the frame 103 of the trailer together with the feeding pumps and tanks of the jacks 107 and 108. This assembly is diagrammatically represented as a whole by reference 120 in FIG. 7.
FIGS. 9 and show a variant wherein the sleeves 106 can be not provided with the collars 106' as it was the case in the preceeding realization. In such a case the flaps 113, 114 and retaining arms 118, 118a are placed at the end of a lower slide-guide l10c provided on the feeder 110, and they are generally designated by 114,.
In said variant, and as better seen in FIG. 10, only the driving-in jack 107 remains, of which the piston 109 has at its lower portion section 1091: having a diameter corresponding to the inner diameter of the sleeves 106 and the height of said section being higher than the height of said sleeves. This will allow an ogive shaped end 109a protrude beneath said sleeves. A sleeve 121 is placed coaxially to the piston 109 and is supported by a spindle 122 connecting the head of two sets of connecting- rods 123, 124 and 123a, 124a, the bases thereof being hinged to two other sets of connectingrods 125, 126 and 125a, l26a, the heads thereof being hinged on a spindle 128 supported by the body of the jack 107.
The connecting-rods are respectively hinged around two axles 129, 130 and around a common axle 131 laterally protruding to delimit fingers cooperating with retaining stops 132 formed by levers 133, 134 hinged at one of their ends on the axles 129, 130 and connected together, at their other end, by an operating handle 135. Springs, such as 136, 137 are designed to connect, for example, the axles 129, 131 to steady arms 138 supported by the body of the jack 107.
The operation of this device is as follows: FIG. 9 shows the piston 109 of the jack 107 in the starting position with the sleeve 12] being above a sleeve 106, which will be placed into the ground and which is retained by the flaps 114,. The portion 1091) of the piston comes out from the sleeve 121 and penetrates into the sleeve 106,.
When the portion 109!) is entirely introduced into the sleeve 106,, the portion of piston 109 having a bigger diameter than the portion 10% bears on the top of the sleeve 121, thus driving the sleeve 106, downward through the retaining flaps 114 While the piston 109 is moving downward, the sleeve is driven into the ground as shown in FIGS. 11 and 11a, while the hinged connecting- rods 125, 126, a and 126a swivel around their axles.
When the driving-in step is completed the stops 132 of the levers 133, 134 cover the axle 131 in the position shown in FIG. 11. At that moment the piston 109 of the jack 107 is taken up, the sleeve 12] remaining in place to retain the sleeve 106, engaged into the ground.
When the piston 109 is sufficiently lifted, a lug 139 (FIG. 10) laterally provided on said piston, comes in contact with a stop 140 supported by the lever 134 which is lifted up as well as the lever 133 to release the axle 131. The springs 136, 137 being stressed, then return the connecting-rods and the sleeve 121 from the position shown in FIG. 10 to the position shown in FIG. 9, and a new operating cycle can start.
In order that the motion of the connecting-rods, when returned to their first position be not too brutal, friction dampers can be provided on the hinging axles 129, 130.
FIGS. 12-20 show that the piston rod 111 of the jack 108 is provided with an arm 141 on which is placed a sleeve 142 which is able to slide with a low clearance on the piston rod 109 of the jack 107.
The sleeve 142 supports on its bottom side, a compression plate 143 advantageously forming a sleeve 143a wherein is placed the upper portion of a sleeve 106 which is placed into the ground.
The rod 109 of the jack 107 forms, just above the sleeve 142, a shoulder 144, thus the sleeve 142 is lowered at the same time as the driving-in rod 109 when said jack 107 is slid into the direction of arrow f, to introduce the sleeve 106 into the ground.
When the rod 109 has sufficiently penetrated into the ground, the plate 143 bears against the surface of the ground and compresses it as shown in FIG. 14, the action of compression being improved by the vibrations which can be transmitted to said plate 143 through the rod 109. The compression thus operated on the ground increases the holding of the sleeve 106.
Finally the jack 107 is controlled to lift-up its rod 109 in the direction of arrowf (FIG. 15), while the rod 111 of the jack 108 is maintained down to cause the sleeve 142 to immobilize both the plate 143 and the sleeve 106 during the lifting of the rod 109. A pole 145 is then placed in the sleeve 106 as shown in FIG. 16. The pole 145 can be of any kind, that is it can be made of metal, of synthetic resin, of wood, of concrete, etc...
FIG. 17 shows a development of this invention wherein the rod 109 of the driving-in jack 107 is axially provided with at least one channel 147 communicating with distributing holes 148 running in the boring ogive 109a. It is thus possible to inject into the ground, either when the rod 109 is entirely introduced, or during introduction of said rod, different materials, such as liquid mortar, concrete, resins, etc..... In this embodiment the sleeve 106 around which the ground is compressed by the compression plate 143, is practically embedded in the ground and it is possible, in some cases, to utilize sleeves shorter than the sleeves usually utilized when an injection of adding and setting material is not practiced.
In some cases, the sleeves 106 must be placed into very light soils and must be able to support poles which can be submitted to important stresses. To take into consideration the possible instability of the ground, this invention comprises an additional development, illustrated in FIG. 18, wherein a container 149 (cylindrically shaped, for example) is placed on the ground, be-
fore lowering the rod 109, and open at the two ends and having a width corresponding to that of the compression plate 143. Into the container is placed some sand, gravel or a shallow concrete as shown at 150.
To engage the sleeve, the process is the same as above described, with said sleeve being introduced through the material contained in the container 149. When the engagement step is completed, the compression plate 143 makes the sand, gravel or shallow concrete to penetrate into the ground while compressing said material around sleeve 106, as shown in 1500 in FIG. 19.
If the rod 109 is provided with the channel 147 utilized to bring an added material, then the sleeve 106 can be embedded on the whole portion thereof engaged in the ground.
The sleeves 106, set into the ground, can be not immediately provided with a stake or a pole or, in some cases, the stakes or poles can be removed. To prevent the sleeves to be filled with soil, it is advantageous, when not in use, to provide them with a cover 151 as shown in FIG. 20.
