Spiral wave slide
A slide body including an upper segment with an upper surface for sliding thereon extending between a first end and a second end thereof, and a lower segment with an upper surface for sliding thereon extending between a first end and a second end thereof. The lower segment includes a flange at the first end thereof, and the upper segment includes a mating element at the second end thereof. The flange and the mating element are adapted to cooperate to locate the first end of the lower segment adjacent to the second end of the upper segment. Also, the flange includes one or more connector elements adapted to cooperate with the mating element for attaching the first end of the lower segment and the second end of the upper segment to each other.
Slide bodies which are spiral in shape (i.e., generally helical) are known. In addition, slide bodies which are substantially linear in plan view, but have generally sinusoidal profiles, are known. In the latter slide bodies, the profile (i.e., the path substantially taken by a user when sliding down a bed portion of the slide body) provides pleasing oscillation effects to the user as the user slides along an upper surface of the slide body. The prior art slide bodies are typically made of a plastic such as polyethylene or structural foamed polyethylene.
However, the slide bodies of the prior art are either formed integrally, or they are formed of parts which are fastened together. Both of these approaches have some disadvantages. First, the slide body which is integrally formed is relatively large, and the larger the slide body, the more difficult it is to form, to transport, and to erect.
Second, where the slide bodies are formed of a number of parts, the prior art parts are fastened together with known fastening systems in arrangements which have certain undesirable characteristics. For instance, a commonly-used type of prior art fastener assembly 10 is shown in
In another typical arrangement of the prior art, slide body parts are adapted to cooperate with each other, as shown in
Also, the prior art connection arrangements shown in
In the arrangement shown in
There is therefore a need for a spiral wave slide which overcomes or mitigates one or more of the defects of the prior art.

The lower segment also includes a flange at the first end thereof extending from the upper surface past the lower surface. In addition, the upper segment includes one or more mating elements at the second end thereof extending from the upper surface past the lower surface. The flange and the mating element are adapted to cooperate to locate the first end of the lower segment adjacent to the second end of the upper segment so that the upper surfaces of the upper and lower segments form a substantially continuous surface for sliding thereon. Also, one of the flange and the mating element has one or more connector elements shaped to cooperate with the other of the flange and the mating element to attach the first end of the lower segment and the second end of the upper segment to each other.
In another aspect of the present invention, upon receipt of the flange in the mating element, the flange and the mating element cooperate to attach the first end of the lower segment to the second end of the upper segment.
In another aspect, the mating element includes a downstream wall and an upstream wall which define a slot in which the flange is receivable.
In accordance with another aspect of the present invention, the upstream wall includes one or more apertures, and the downstream wall includes a preselected portion which registers with the aperture. The aperture is at least partially defined by one or more surfaces disposed in the upstream wall.
In yet another aspect, the connector element is configured for engagement with one or more of the surfaces in a snap fit upon receipt of the flange in the slot, to attach the upper and lower segments to each other.
In another of its aspects, the flange includes a substantially planar face element adapted for engagement with the upstream wall when the flange is received in the slot, and each connector element protrudes from the face element.
In yet another aspect of the present invention, each connector element has a bottom end positioned distal to the upper surface of the lower segment and a top end located between the bottom end and the upper surface. Also, in each connector element, the top end protrudes further from the face element of the flange than the bottom end.
In another aspect of the present invention, there is provided one or more fasteners for securing the flange and the mating element to each other.
In another aspect, the flange is connected by the fastener to the preselected portion, to secure the lower segment and the upper segment to each other.
In another of its aspects, the connector element has an indented surface for directing the fastener substantially along a predetermined path through the preselected portion of the downstream wall upon insertion of the fastener therein.
In yet another aspect, the lower segment additionally includes one or more tabs projecting from the lower surface thereof, each tab being substantially aligned with a preselected portion so that the fastener connects all of the tab, the preselected portion of the downstream wall, and the flange, to secure the lower segment and the upper segment to each other.
In another aspect, the invention includes one or more plugs positioned at the first end of the lower segment and one or more cups positioned at the second end of the upper segment. Each plug is nestable in each cup, and is supported by each cup when nested therein. Also, each plug is nested in each cup respectively upon receipt of the flange in the mating element.
In yet another aspect, a fastener connects each cup and each plug respectively, to secure the lower segment and the upper segment to each other.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention will be better understood with reference to the attached drawings, in which:
Reference is first made to
As shown in
It will be understood that the slide body of the invention may have more constituent body parts than the upper segment 41 and the lower segment 53 shown in
Preferably, the slide body additionally includes one or more fasteners 77 for attaching the flange 65 and the mating element 67 to each other (as will be described), to secure the upper segment 41 and the lower segment 53 to each other. As shown in
As can be seen in
Preferably, the connector element 69 is configured for engagement with one or more of the surfaces 89 when the flange 65 is received in the slot 83 in a snap fit, to attach the upper and lower segments 41, 53 together. As can be seen in
As can be seen in
This wedge-like configuration of the connector elements 69 is important because it enables the flange 65 to be fully received in the slot 83, and it results in each connector element 69 snapping into the aperture 85, once the flange 65 is fully inserted into the slot 83. Preferably, the thickness of the flange 65 at the upper end 95 is significantly greater than the width of the slot 83, i.e., it is desirable that the top end 95 should extend into the aperture 85 to a significant extent when the flange 65 is fully inserted in the slot 83, to facilitate engagement of the connector element 69 with the surfaces 89, and also to impede removal of the connector element 69 from the aperture 85. Accordingly, after the flange 65 is fully inserted into the slot 83, the connector elements 69 attach the upper and lower segments to each other, to facilitate insertion of the fastener 77.
As can be seen in
As can be seen in
As can be seen in
It is also preferred that the connector element 69 includes a ledge 109 with the indented surface 105, for supporting and directing the fastener 77 along the predetermined path upon insertion of the fastener 77 in the preselected portion 87.
As can be seen in
In the preferred embodiment, one or more fasteners 123 connects each of the cups 115, 117 to the plugs 119,121 respectively, to secure the lower segment 53 and the upper segment 41 to each other (
It will be understood that, as shown in
For example, another embodiment of the slide body of the invention 239 is disclosed in
In another embodiment, a slide body 439 of the invention is disclosed in
In use, and as can be seen in
As described above, when the flange 65 is seated in the slot 83, the connector elements 69 snap into position in the apertures 85, engaging one or more of the surfaces 89 which define the aperture 85 as they snap into place. At this point, the upper segment 41 and the lower segment 53 are attached together, and held in place by the cooperation of the connector elements 69 with the surfaces 89 defining the apertures 85 to form a relatively secure connection. Because this connection is relatively secure, an installer (not shown) is not required to hold the upper and lower segments together while the fasteners are installed.
Next, the fasteners 77 and 123 are installed. As can be seen in
As can be seen in
In another embodiment, the upper segment bed portion 43 has an upper segment bed profile 50 which substantially defines a path taken by the user sliding from the first end 47 to the second end 49 of the upper segment 41 (
As described above, in another embodiment, the slide body 239 includes upper, middle, and lower portions 225, 227, and 229. In this embodiment, the middle portion has a middle bed profile 254 which substantially defines a path taken by the user sliding from a first end 256 to a second end 258 of the middle portion 227.
