Abstract
A slide assembly comprises an upper section 21, a lower section 25 and a middle section 23 which detachably connect. Each section has an upper surface 26, a lower surface and side walls 27. The side walls of the middle section extend inwardly from the upper surface to the lower surface such that the section has a keystone shape when viewed side on. The side walls of the upper and lower sections are correspondingly shaped. The upper and lower sections may be connected to the ground 28 and 29. The middle section can be supported above ground between the upper and lower sections without the need for its own ground support. There may be additional support provided by interlocking means beneath the upper surface of the sections. The aim is for a modular slide that is convenient to transport and assemble and will not fail in use.
Description
A Slide Assembly
Field of the Invention
This invention relates to a slide assembly, particularly one 5 formed of multiple parts for assembly at the point of use.
Background of the Invention
A slide is a well-known playground or garden fixture comprising of a metal, wooden or plastic inclined member with a smooth upper surface so that a user can slide down the surface. The surface may be straight or curved or wavy, and may be supported at its upper end by a fixture such as a ladder, climbing frame or playhouse.
In some countries, a slide is known as a playground chute, sliding pond or pon.
Due to the relatively large size and shape of a slide, it is difficult to transport and will occupy a large amount of space in a van or truck, which is inefficient. Although modular slides, i.e. slides that are provided in sections for assembly at their point of use, are known, because of the safety aspect which requires that the slide will not fail when used, these known slides tend to rely on complex connection mechanisms, which may ultimately fail over time, and may require expert assembly at the point of use.
It is an aim to provide an improved slide assembly.
Summary of the Invention
A first aspect of the invention provides a slide assembly, comprising: first, second and third sections which detachably connect together, each section having an upper and lower surface and side walls, the third section being arranged to locate between the first and second sections by means of first and second end walls, which are generally transverse to the side walls and have an external surface the majority of which has a profile which extends inwardly from the upper surface to the lower surface to provide generally an overall wedge shape when the third section is viewed side-on, an end wall of each of the first and second sections being formed with a correspondingly-shaped surface so that, in use, the end walls of the third section abut said end walls of the first and second sections such that the third section can be supported above ground between the first and second sections without the need for its own ground support.
The supporting of the third section between the first and second sections is in the manner of a 'keystone' by virtue of its shape and the corresponding shape of the walls it abuts at each end. This means that the slide can be broken down into at least three sections, providing a transportable product that can be compact, and when assembled the third section has strong support without the need for its own ground support. If additional engagement portions are provided between adjacent sections, the wedge shape minimises, or at least reduces, the downwards forces imposed on said portions to improve lifespan of the product.
The end walls of the third section may have a flat, inwardly tapering profile. These may be identical at both ends.
The inwardly tapering profiles of the end walls may be angled so that they have a converging angle of between 15 and 20 30 degrees, e.g. 18 degrees, substantially.
The first and second sections may be arranged to be in fixed relation to an underlying surface, e.g. the ground.
When assembled, the first section may be the upper section, the third section the middle section and the second section the lower section, and the upper end wall of the first section may further comprise means for attachment to a ladder, climbing frame or playhouse structure.
The second section may further comprise means for anchoring it to an underlying surface, e.g. the ground.
The abutting end walls may further be arranged with interlocking means, e.g. beneath the upper surface, to provide additional support.
The interlocking means may comprise, on one of the abutting end walls, a plurality of fingers extending from, or from the region of, said end wall, each arranged to locate within a corresponding groove or channel provided in, or in the region of, the other end wall with which it is to abut.
The plurality of fingers on, or in the region of, each said end wall may each comprise a transverse groove or channel at a predetermined distance along the finger configured in use to receive a bar which extends through said transverse grooves or channels.
Said other wall may comprise a transverse channel through which the bar passes.
A second aspect of the invention provides a slide assembly, comprising: an upper section, a middle section and a lower section, each having an upper sliding surface, a lower surface and lateral side walls, the middle section having end walls for abutting a respective end wall of the upper section and the lower section, said end walls of the middle section having an inwardly-converging profile from the upper surface to the lower surface to provide an overall generally wedge-shaped profile when viewed side-on, said end wall profiles corresponding with the abutting surface of the upper and lower sections so that the 5 middle section can be supported between the upper and lower sections without the need for its own ground support, the middle section further comprising means to interlock at or in the region of each end wall with the other sections by means of a transverse bar that extends through a groove or channel underneath the 10 upper sliding surface.

Detailed Description of Preferred Embodiments
The preferred embodiment disclosed herein provides a slide assembly suitable for use in a garden or playground. The assembly can be provided in disassembled form, making it easily and efficiently transportable from factory/distributor to place of use, where it can be safely and easily assembled. The slide assembly comprises three separate slide sections, namely an upper, lower and middle section, which means that the sections can be compactly stored and transported, e.g. in nested form.
The middle section is generally wedge-shaped (when viewed in cross-section or from the side) and supported when assembled by the adjacent sections in the manner of a bridge or arch 'key stone' so that it requires no ground support of its own and is sturdy and stable when assembled between the two fixed outer sections.
Referring to Figure 1, which is useful for understanding the general principle, there is shown in cross-section part of an upper section 1, part of a lower section 3 and a middle section 5 in assembled form. Each section 1, 3, 5 has a smooth upper sliding surface 7, a lower surface 9 and generally transverse end walls 11, 13, 15, 17. Only the end walls of the lower and upper sections, that abut the middle section, are shown. In practise, there are also provided lateral side walls upstanding from the upper surface 7 to prevent a user from falling sideways from the slide.
It will be seen that the end walls 11, 13 of the middle section 5 taper inwardly from the upper to lower surfaces 5, 9, i.e. they converge towards a distant point, indicated by dotted lines with a convergence angle a.
The overall side profile of the middle section 5 is therefore that of a wedge. The abutting surfaces 15, 17 of the lower and upper sections 1, 3 are correspondingly shaped. Provided the lower and upper sections 1, 3 are mounted in fixed relation to the ground, then the middle section 5 will remain supported as shown without the need for its own ground support. The stability is improved by virtue of the fact that the majority of the end wall surfaces are tapered in this way, making the assembly strong and less likely to fail. The end wall surfaces are substantially planar and have the same, but oppositely oriented, taper.
Referring now to Figure 2, a first embodiment slide assembly 20 (hereafter "slide") is shown in assembled form. The slide 20 10 employs the Figure 1 keystone principle, employing in this case a convergence angle a of approximately 18 degrees. The slide 20 comprises an upper section 21, a middle section 23 and a lower section 25. The upper sliding surface is indicated generally by reference numeral 26, and the upstanding lateral 15 walls by reference numeral 27.
Each section 21, 23, 25 is in this case curved, but each can be planar. The upper and lower sections 21, 25 are provided with means to secure said sections in fixed relation to the ground, indicated by arrows 28, 29. In the case of the upper section 21, this may be by means of a ladder or attachment to a playhouse or climbing frame, for example. In the case of the lower section 25, this may be any suitable anchoring means, e.g. posts or spikes that embed into the ground.
Figure 3 shows the Figure 2 embodiment in side view, where the converging end walls 31, 33 of the middle section 23 abut adjacent walls 35, 37 of the upper and lower sections 21, 25 having a surface profile the majority of which corresponds to the adjacent wall they abut, i.e. in the manner shown in Figure 1. The separate sections 21, 23, 25 by virtue of their dimensions and shape can be provided disassembled, nested and easily transported for assembly.
In theory, provided the upper and lower sections 21, 25 are securely fixed, the middle section 23 will support the weight of users. However, for further safety, the embodiment also provides interlocking connecting means, to be described below.
Figure 3 also provides typical dimensions, which may of course vary. The width of the Figure 3 slide is 570 mm.
Referring to Figure 4, the upper, middle and lower sections 21, 23, 25 are shown in exploded view. It will be seen that interlocking means are provided between adjacent sections, in the form of fingers 40, 42 which project from the upper and lower sections 21, 25 and channels 44, 46 formed in the middle section 23, specifically within part of the tapering end walls 31, 33. The fingers/channels may be arranged the opposite way around, i.e. fingers on the middle section 23 and channels on the upper and lower sections 21, 25.
Figure 5 shows the interlocking means in more detail, 20 specifically from the underside between the upper section 21 and the middle section 23.
The upper section 21 has on its underside a central, reinforced portion 50; on either side of this portion extend a pair of fingers 51 (hereafter "overhanging fingers") with part-cylindrical grooves 53 transverse along axis X-X. A pair of further fingers 55 (hereafter "underhanging fingers") extend in the same direction, nearer to the side walls.
The middle section 23 has on its underside a central, reinforced portion 56; on either side of this portion are provided a pair of grooves or recesses 59 shaped and dimensioned so as to receive the overhanging fingers 51 in a close-fitting manner.
transverse cylindrical channel 61 extends through the reinforced portion 56 and is aligned with the grooves 53 which locate either side of said portion when the two sections 21, 23 are connected. A pair of further grooves or recesses 57 are provided on the underside, nearer to the side walls, shaped and dimensioned to receive the underhanging fingers 55 in a close-fitting manner, when the sections 21, 23 are connected.
As indicated in Figure 5, the cylindrical bar 48, which is preferably metal, is threaded through the aligned grooves 53 and the transverse channel 61, to secure the interlocking engagement. Figure 6 shows said bar 48 in final position when the upper and middle sections 21, 23 are interconnected. The diameter of the bar 48 is such as to closely conform with that of the grooves 53 and channel 61 so that it can slide easily within, but is close-fitting such that it will not easily be freed without user effort.
The same or a similar interlocking means 42, 46 is/are provided between the lower and middle sections 25, 23.
As shown in Figure 7, which indicates the engagement between the lower and middle sections 23, 25, the overhanging fingers 51 may be shaped on their upper sides (not-visible in Figure 5, which is from the underside) with protrusions 70 (or recesses) which mate with correspondingly shaped recesses (or protrusions) on the lower surface of the grooves/recesses 59 into which they locate. The same may also apply to the outer fingers 55. The fingers will therefore act as clips.
End caps (not shown) may locate over the ends of each bar 48. Screws 65 (see Figure 6) may be used to secure the bar 48 in position within the channel 53.
The provision of the above-described interlocking means at the join between the sections 21, 23, 25 ensures even greater stability; the keystone wedge shape minimises the downwards forces imposed on the interlocking sections during use, which may otherwise weaken the interlocking means over time. In the event of any part failing, the keystone wedge shape of the middle section 23 will ultimately prevent failure. The interlocking means also prevents unwanted lateral movement, with the plural fingers preventing a possible hinge point.
Manufacture is straightforward, particularly in the case of plastics materials, in that moulding can provide the sections 21, 23, 25 which are shaped and dimensioned, possibly such that they nest when stored and/or transported. Less secondary manufacturing processes are required as only the two channels 61 need drilling in the middle section 23.
The above-described embodiment is particularly suited to play slides for use in gardens or playgrounds. The principles and 20 advantages described herein can also be applied to other forms of slide or chute, however.
It will be appreciated that the above described embodiments are purely illustrative and are not limiting on the scope of the invention. Other variations and modifications will be apparent to persons skilled in the art upon reading the present application.
Moreover, the disclosure of the present application should be understood to include any novel features or any novel combination of features either explicitly or implicitly disclosed herein or any generalization thereof and during the prosecution of the present application or of any application derived therefrom, new claims may be formulated to cover any such features and/or combination of such features.
