Abstract
Description
- The invention relates to a means of mounting and adjusting two tubes which can slide inside one another.
- When constructing playground equipment comprising a frame of metal rods or tubes, each metal tube is normally secured to a base in order to provide a stable and safe item of playground equipment.
- U.S. Pat. No. 6,095,950 discloses an example of such an item of equipment comprising three posts which at their bottom are provided with feet being secured to the base.
- This construction does not permit immediate adjusting or setting and therefore requires a carefully erected base. Add to this that problems may occur in the event that the foundation subsides or the posts deform which will require the adjusting of one or more of the posts at the base. Any such adjustment will have to be performed by adjusting the actual attachment to the base.
- It is the object of the invention to facilitate the installation of the playground equipment as well as the adjustment of the supporting metal tubes, and this is obtained according to the invention when the interior of the tubes is provided with inwardly projecting grooves in which a wedge is fitted having a cross sectional shape which causes the diameter of the interior tube to expand once the wedge is tightened outwards towards the outer tube for assembly of the tubes.
- By configuring the interior tube so that it is an expansion body, it becomes possible in this simple manner to tighten this body from without in order to secure the outer tube in a manner which permits adjustment even after instalment of the playground equipment.
- This permits expansion to be obtained from without by means of bolts or the like so as to obtain a relative displacement of the telescopic tubes in relation to each other.
- Since each groove in the interior tube is configured in the tube wall by some kind of folding, the tube will form an expansion body which will expand upon tightening of the wedges, and contract and thus end the expansion force upon disengagement of the wedges.
- As disclosed in
claim 2, by configuring the grooves and the wedges with a shape on the sides which slopes towards the outside of the tubes, an evenly distributed expansion of the interior tube against the outer tube is ensured. - As disclosed in
claim 3, by configuring several grooves along the tube, such as three grooves at equal distances to each other, a very uniform compression and thus assembly of the tubes is obtained. - As disclosed in
claim 4, by providing the wedge body with one or more thread holes extending from without and inwards, and by also providing holes through the outer tube, an outwardly directed tigthening of the wedges is easily and safely obtained by means of bolts through the holes. - Finally, as disclosed in
claim 5, it is expedient to provide the interior tube with a base plate at the end, whereby the adjustable assembly can be established at the lower part of the tube where it causes no inconvenience to the user of the playground equipment. - An example of an embodiment of the means according to the invention will be disclosed in the following section with reference to the drawing, in which
- FIG. 1 shows the lower portion of a column with base plate,
- FIG. 2 is a cross sectional view of the tube in its non-tightened position seen in the direction11-11 in FIG. 3,
- FIG. 2a shows the same cross section in the tightened position seen in the direction IIa-IIa in FIG. 3
- FIG. 3 is a longitudinal view through the tube seen in the direction111-111 in FIG. 2, and
- FIG. 3a shows the same section with the tube in its tightened position seen in the direction IIIa-IIIa in FIG. 2a.
- The invention will be described in closer detail as a column or a supporting tube, for instance by way of a tube in an article of playground equipment.
- One or more such tubes constitute the bearing structure to which various playground accessories are secured, such as climbing ropes, slides, ladders, and the like.
- Such an item of playground equipment must be firmly secured to its base in order that it will tolerate the often great forces to which it is subjected during use.
- One or more of the tubes may be constructed in accordance with the invention and as shown in FIG. 1, which shows the lower part of a tube1.
- An internally extending
tube piece 2 is inserted from beneath into this tube 1, whichtube piece 2 for instance by means of a screw/wedge assembly is anchored to a base plate 7 which can be secured to a base which is not shown for instance by means of three bolts. - This base can be a buried or cast anchor, a floor or a footing which constitutes the support. The
interior tube 2 may form the foundation on its own merely by being buried or cast. - The internally extending
tube piece 2 is, as shown in FIGS. 2 and 3, configured as a tube being profiled in its cross section and in the shown example comprising threerecesses forming grooves 4 which are formed so that the width of the groove is largest towards the inside since the side faces taper inwards towards the outside as shown. - The
grooves 4 extend in the longitudinal direction of the tube piece to such an extent, i.e. length, that the necessary adjustability of the outer tube 1 can be obtained. This can be in the entire length of thetube 2 or part thereof. - In these grooves4 a
wedgeshaped expansion body 3 is inserted, as shown in FIGS. 2 and 3. - The
body 3 fills the inside of thegroove 4 as implied in FIGS. 2 and 3. - The wedge-
bodies 3 are further provided with threadedholes 5 forbolts 6 extending throughholes 10 in the outer tube 1 as shown in the drawing. - Thus fitted the
tubes 1 and 2 can be displaced longitudinally in a telescopic manner. - Once the required position of the tube1 has been established, the
bolts 6 are tightened, whereby thewedge body 3 will be drawn outwards in the groove, causing these to expand transversely. - The internally extending
tube piece 2 will thus expand and squeeze against the inside of the outer tube 1 as shown in FIGS. 2a and 3 a. - The
tubes 1 and 2 are thus locked together in a reliable manner since a uniform pressure distribution will take place among the tubes. - The assembly is easily disengaged, simply by loosening the
bolts 6 and releasing thewedge 3, whereby thetube piece 2 will reduce its circumference enabling the tubes to slide in relation to each other. - This simplifies the mounting, and there is no longer any need for a complete levelling of the base.
- Besides an easier assembly, the possibility is obtained of subsequent adjustment of the individual tubes1 on the base, merely by loosening the
bolts 6 and tightening them again after the adjustment. - The
tubes 1 and 2 are preferably made of steel but can also be made of other metals or perhaps plastic. The same applies to thewedge elements 3.
