[0151] FIG. 18 shows the support bases 1 of FIG. 12 (FIG. 18(A)) and FIG. 10 (FIG. 18(B)), wherein the L-shaped elements 3 and the base element 4 comprise a ground spike 30 underneath.

[0152] FIG. 19 shows (at the top) an extension element 31 connected to the foot part 3C of an L-shaped element 3. FIG. 19 shows (at the bottom) an element, which comprises a shaft part 32 and a blade part 33, connected to the foot part 3C of an L-shaped element 3.

[0153] FIG. 20 shows a support base 1 where each L-shaped element 3 is provided with integrated fastening means 36 such that, when the L-shaped elements 3 are brought into close proximity, fastening means 36 on one L-shaped element 3 engage with an adjacent L-shaped element 3, thus creating a stable and fixed support base 1. The ring member 18 is in effect divided into a number of segments, wherein each segment is integrated in an L-shaped element 3.

[0154] In FIG. 21 is illustrated the first holding means in the shape of a ring member 40. The ring member is provided with a slit 41 such that the diameter of the inner opening 42 may be enlarged in order to release the engagement between the ring member 40 and the upright portions of the L-shaped members (not illustrated). As is the case with most of the other embodiments relating to the first fastening means and particularly in the shape of a ring member the ring member is provided with guide grooves 43a, 43b, 43c, 43d. The guide grooves serve to guide and hold the upright portion of the L-shaped members. Friction enhancing means are provided, in order to mutually increase the friction between the upright part of the L-shaped members and the ring.

[0155] In order to firmly affix the ring member 40 to the pole and the upright portions the slit 41 may be closed by a releasable closing mechanism 44. In this embodiment the closing mechanism 44 incorporates two flanges 45, 46. The flanges 45, 46 are provided with a thread such that a threaded axle 47 can be arranged in the threaded holes in the flanges 45, 46. By rotating the handle 48 the size of the slit may be enlarged or diminished. In this manner the ring shaped member 40 may be tightened around the pole and the upstanding upright parts of the L-shaped members. Many other manners of tightening/closing and opening the slit may also be implemented.

[0156] Turning to a further embodiment of the invention this will be illustrated with respect to the FIGS. 22-27. In this embodiment the first fastening means is also in the shape of a ring, but in this embodiment the first fastening member 18 comprises two parts as will be explained with reference to the FIGS. 22-24. In FIG. 22 the assembled ring is illustrated and in FIG. 23 is illustrated the over-cup and in FIG. 24 the under-cup. Starting with the under-cup illustrated in FIG. 24 the under-cup comprises a bottom plate 50. Along the outer periphery of the bottom plate 50 is provided a peripheral wall 51 arranged substantially orthogonal to the bottom plate 50. Furthermore, in the bottom plate 50 openings are made for the guide grooves 43a, 43b, 43c and 43d. Also upstanding from the bottom plate 50 substantially parallel to the peripheral wall 51 are release tabs 52. The release tabs are arranged adjacent the guide grooves 43c on either side of the guide groove and the release tabs 52 are furthermore biased towards each other. In this embodiment the under ring 55 is made from injection moulded plastic and as such the release tabs 52 are moulded slightly leaning towards each other across the guide groove in order to create a degree of biasing.

[0157] Also provided upstanding from the bottom plate 50 of the under-cup 55 is a number of holding legs 53. At a distal end of the holding legs 53 is provided a hook.

[0158] The under-cup is further provided with biased means. In this embodiment the biased means are in the shape of injection moulded biased plastic leaf springs 56 arranged along the outer periphery of the peripheral wall 51. Alternatively, normal helical springs may be provided, and for this purpose the bottom plate 50 is provided with spring towers 57 suitable to accommodate and guide a helical spring arranged in parallel to the peripheral wall 51.

[0159] Turning to FIG. 23 the over-cup 60 is illustrated. The over-cup has a top plate 61 and a peripheral wall arranged along the outer perimeter of said top wall. The outer wall may be seen in FIG. 22 reference number 62.

[0160] A second central aperture having a second diameter larger than the diameter of the first diameter through which the pole is supposed to pass is provided in said top plate 61. The over-cup 60 is also provided with guide grooves 43a-43d.

[0161] Adjacent to at least one guide groove is provided flexible engagement means 64 projecting into the guide grooves. The engagement means 64 are suitable to engage the corrugations, serrations, teeth, ridges or grooves provided on the side faces of the upright part of the L-shaped members such that as the ring member 60 as assembled in FIG. 22 slides down the upright parts of the L-shaped members the engagement means 64 will click or be deviated as it passes each corrugation, serration or tooth on the side faces of the L-shaped members.

[0162] Once the ring 60 has been lowered sufficiently down the tapered upright part of the L-shaped members the L-shaped members will be in firm engagement with the pole (not illustrated) and the engagement means 64 will be locked against a corrugations, serration, teeth, ridges or grooves provided in the side faces of the L-shaped member. In this manner a secure and stable connection is created between the pole and pole basis.

[0163] In order to release the ring shaped member 60 from the engagement with the L-shaped upright part the over-cup and the under-cup are further squeezed together, whereby the release tabs slide upwards on an angular face 65 of the engagement means 64. As the engagement means are in very close proximity to the side faces of the upright part of the L-shaped member, the release tabs will cause the engagement means 64 to flex away from the L-shaped members thereby releasing the grip of the ring against the L-shaped members making it possible to lift the ring shaped member further up until it disengages completely from the tapered L-shaped members.

[0164] The holding legs 53 described with reference to FIG. 24 provided on the under-cup will engage flanges 66 provided on the over-cup such that the hook shaped member will hinder the over and under-cup in disengaging, but will allow the over-cup and under-cup to be further depressed, i.e. such that the distance between the top plate 61 of the over-cup and the bottom 50 of the under-cup will come closer to each other. Bringing the two closer will cause the release tabs 52 to slide upwards along the face 65 of the engagement means 64 thereby flexing the engaging means 64 as already described above.

[0165] In FIG. 25-27 is disclosed an alternative embodiment but working on the same principle that a displacement vertically or parallel to the pole's longitudinal direction of an over-cup and an under-cup will create a release mechanism. Whereas the release mechanism described above with reference to FIGS. 22-24 was created by a vertical movement creating a sideways flex of the engagement means 52 the alternative embodiment illustrated in FIGS. 25-27 creates the release by swinging engagement members out of engagement with the serrations on the upright part of the L-shaped members. In order to ease the explanation of the embodiment like features will be denoted with the same reference numbers as was used above with respect to the first embodiment described with reference to FIGS. 22-24.

[0166] In FIG. 25 the assembled fastening means is illustrated having an under-cup 55 and an over-cup 60. As was the case in the first embodiment the under-cup 55 illustrated with reference to FIG. 27 has a bottom plate 50 where an outer periphery is provided with an upstanding peripheral wall 51. Holding leg 53 provided with hook means are also provided for engagement with flanges 66 provided on the over-cup.

[0167] On FIG. 26 the over-cup 60 is illustrated where the engagement means 68 has a distinct engagement section 69. The engagement section 69 is designed to actively engage the serrations, teeth or corrugations or the like provided on the side faces of the L-shape members. In the under-cup is provided deflection blocks 70. The deflection blocks are dimensioned and provided with an oblique surface 71 such that as the over-cup and the under-cup are assembled the oblique surface 71 will engage the release section 72 of the fastening means 68 thereby swinging the engagement section 69 out of engagement with the serrations, corrugations or other friction enhancing properties on the side face of the L-shaped members. The action between the oblique surface 71 and the release section 72 occurs as the under-cup and over-cup are squeezed together in the same fashion as the embodiment of the invention described with reference to FIGS. 22-24.
