This invention relates to playground equipment and, in particular to free standing playground climbing structures, such as simulated rock walls.
Climbing structures, such as rock walls, are employed more and more frequently in indoor and outdoor recreation or playground areas. Typically, a climbing structure comprises a plurality of panels having a formed surface with hand and foot holds thereon. The formed surface can simulate a desired texture, and often is formed to simulate a rock wall. The panels are then rigidly connected together. The system commonly employed to connect the panels together does not allow for variation in the set up of the panels. That is, the angle or orientation between panels cannot be varied. Nor can the orientation of a panel be changed. The panels for currently available climbing structures or walls only fit together in certain predetermined orientations. Additionally, connecting elements are visible in some climbing structures.
A climbing wall assembly or climbing structure made in accordance with the present invention comprises at least two adjacent climbing panels and at least three support posts. The climbing panels are mounted between the support posts and adjacent climbing panels share a common support post.
Each climbing panel comprises a front surface, a back surface, a first side surface and a second side surface. The front and back surfaces of the panels are configured to be climbed, and can, for example, have the appearance of a rock wall. A first of the two panels has a connecting element on at least its first side surface and a second of the two panels has a connecting element on its second side surface. The connecting elements of the panels defining an elongate tube which surrounds a support post. Preferably, the tube defined by the connecting elements surrounds substantially the entire above ground height of the support posts. The connection of the panels to the support posts enables two adjacent panels to be oriented relative to each other at a desired angle.
In accordance with one aspect of the invention, the connecting elements of the climbing panels comprise hinge members, there being at least one hinge member a connecting side of each panel. The hinge members of the adjacent panels are vertically offset from each other and axially aligned with each other when the panels are positioned adjacent each other, to form or define the elongate tube through which the support post extends. The tube defined by the hinge member, and through which the support post extends, has a diameter at the top and bottom thereof that is dimensioned to engage the support post, such that there will be a tight fit between the support post and the hinge member at the top and bottom thereof. The central portion of the tube defined by the hinge member has a diameter greater than the diameter of the support post.
In accordance with another aspect of the invention, the climbing wall or climbing structure can comprise three or more climbing panels. In this situation, the panels of the assembly comprise two end panels with the remainder of the panels being center panels. The end panels have the at least one hinge member along only one side thereof and the center panels have hinge members on both their first and second side surfaces. Hence, the end panels can be connected to only one other panel and the center panels can be connected to two other panels. To enable the end panels to be supported by two support posts, end panels include a vertically extending passage which is horizontally spaced from the hinge member of the panel. The end panel passage is sized and shaped to receive a support post.
In accordance with a further aspect of the invention, caps or closures are provided to close the openings at the top of the climbing structure formed by the end panel passages and the hinge members. A first cap is sized and shaped to close the opening formed by the end panel passages. A fastener extends through the cap and into a plate within the post to secure the cap to the post. A second cap includes a cap body sized and shaped to close the opening defined by the hinge member and a flange or finger which extends from the cap body across a gap between adjacent panels. At least one fastener is provided which extends through the cap body of the second cap into a plate in the support post. A second fastener can also extend through the cap flange into the adjacent panel.
The hinge member at the top of the climbing structure can have a recess formed its upper surface, and a recess can be formed in the upper surface of the adjacent panel at the edge of the panel adjacent the upper hinge member. The recesses are sized and shaped to receive the cap so that the cap will be substantially flush with the upper surface of the climbing structure.
In accordance with a further aspect of the invention, the climbing structure includes a plurality of base members to which the support posts are mounted. Preferably the support posts are removably mounted to the base members. The base member includes a mounting post to which the support post is mounted. The mounting post can be a sleeve which receives the support post, or which is received in the support post. A fastener extends through the support post and the sleeve to secure the support post to the sleeve. The base member includes a plate which surrounds the mounting post above the fastener. In an assembled structure, the panel rests on the plate, such that the panel is supported above the level of the fastener.
In one embodiment, the base member comprises a pole which is set into ground. An upper portion of the pole defines the mounting post. In a second embodiment, the base member comprises a surface engaging plate, and the mounting post extends upwardly from the plate. A plurality of anchors extend through the base plate into surface upon which the plate sits.

The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what we presently believe is the best mode of carrying out the invention. Additionally, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
A climbing structure assembly 10 constructed in accordance with the present invention is shown generally in
The climbing structure 10 actually comprises two types of panels—end panels 14 and center panels 16. Further, the end panels 14 can be classified as right end panels 14a and left end panels 14b. The panels 12 all comprise front and back surfaces 18, an upper surface 20, a bottom surface 21, a first side 22 and a second side 24. With reference to the figures, the first side 22 is the right side of the panel and the side 24 is the left side of the panel.
The panel front and back surfaces 18 have a desired configuration or shape. For example, the panel surfaces 18 can be configured to look like a rock wall. The surfaces 18 are provided with a plurality of foot and hand holds 26, enabling the structure 10 to be climbed. Foot and hand holds 26 are provided on both the front and back surfaces of the panels, and preferable, for each foot and hand hold 26 on the panel front surface; there is a corresponding foot and hand hold on the panel back surface. The corresponding or opposing hand and foot holds are connected together in such a way so as to increase the structural integrity of the panel. The manner in which the foot and hand holds are formed and how they are mounted to the panel are well known to those skilled in the art and are not described herein. As seen in
Turning to
The connecting sides of the center panels 16 comprise at least one connecting element, shown to be in the form of a hinge member 40a along side 22 and at least one hinge member 40b along side 24. The hinge members 40a and 40b are offset from each other, such that when the panels 16 are positioned adjacent each other, the hinge members from one panel will be axially aligned with the hinge member from the adjacent panel.
The connecting sides of the end panels are also provided with at least one connecting element, again, in the form of a hinge member. However, to enable the right and left end pieces to mate with the hinge members of the center panels, the right panel 14a has hinge members 40b along its left side 22 (with respect to
As seen in the Figures, each panel is provided with two hinge members on their respective connecting sides, and the hinge members mesh together, such that the top of one hinge 40b is adjacent the bottom of the hinge 40a. Thus, in an assembled climbing structure 10, there will be substantially no gap between vertically adjacent hinges joints. Although the panels are shown to include two hinge members on each connecting side, the panels could be provided with only one hinge member on their respective connecting sides or three or more hinge members on their respective connecting sides. Preferably the hinge members 40a,b are all of the same length
The hinge members 40a,b of the center and end panels define tubes 41 having an inner surface 42 (
As seen in
The panel sections 12 are maintained in place by support posts 50. The posts 50 are sized and shaped to pass through the hinge members 40a,b. As noted above, the hinge tubes 41 have inner diameters at the tops and bottoms thereof which form a tight fit about the support posts 50. This tight fit rigidly maintains the panel in place relative to the post, to substantially prevent movement of the panel in an assembled wall 10. The support posts 50 are preferably hollow and have outer surfaces shaped complimentarily to the inner surface 42 of the hinge members. As noted above, each panel 12 is supported by two support posts 50. The center panels 16 are mounted to the support posts which pass through the hinge members 40a,b of the two connecting sides of the panels; and the end panels 14a,b are mounted to a supporting post 50 which passes through the hinge members of its connecting side and to a support post 50 which passes through the end panel's passage 30.
As noted above, the hinge members of respective adjacent panels mesh together. Hence, the hinge members of adjacent panels for a continuous passage through which the support post 50 extends. Thus, the combined length of the hinge members 40a,b from two adjacent and connected panels surrounds substantially the entire above ground length of the support post 50 (i.e., the length of the support post above any ground cover GC). That is, substantially no part of the support post is exposed, and a climber is presented with only the front and back surfaces of the climbing wall 10. This allows for the placement of more foot and hand holds 26 on the front and back surfaces 18 of the panels.
In positioning one panel 12 relative to another, the support post 50 will define a pivot point about which the panels 12 can pivot or rotate (during assembly). It will be understood that the panels will be fixed in place once the structure 10 is fully assembled. Hence, by providing a pivotal connection between adjacent panels, the orientation of one panel relative to another can be selectively designed. Further, because the end surfaces 22a,b and the outer surface of the hinge member are shaped complimentarily to each other, the size of any gap between adjacent panels will not be affected by the angle formed by two panels, as occurs, for example, when two bodies having flat surfaces are rotated relative to each other.
The climbing structure is also provided with caps to close the upper end of the tube formed by the hinge members 40a,b and the passage 30. A first cap 52 (
A second cap 62 (
The cap 62 is formed as a one-piece cap. However, the cap 62 could be replaced with two parts. A cap 52 could be used to close the hinge member tube, and a separate bridging element could be provided to close the gap between adjacent panels.
Although the caps 52 and 62 are described to be secured in place using fasteners or the like, the caps can be secured in place by other means as well. For example, the caps could each be provided with a collar that extends into the hinge tube or the passage 30 to frictionally hold the cap in place. Such a collar could frictionally engage either the inner surface of the hinge member (or end panel passage) or the inner surface of the support post.
The second cap 62 is received in a recess in the adjacent panel sections, so that the upper surface of the cap 62 is generally flush with the upper surface of the panel sections, as seen in
The cap 52 is shown to rest on the upper surface of the end panels. (see
Lastly, to facilitate assembly (or disassembly), the climbing structure 10 is provided with base members to which the support posts are mounted. A first embodiment of a base member is shown in
The second base member (
Although the base member mounting posts 86, 86′ are described to be hollow sleeves which receive the support posts 50, the support posts could, alternatively slide over the mounting posts, such that the mounting posts extend internally of the support posts.
The various features of the climbing unit 10 give the unit several distinct advantages over currently available free standing climbing structures. Initially, the hinged connection of the panel sections to the support posts allows for the panel sections to be positioned relative to each other in virtually any desired angular orientation, over an arc of about 180°. This ability to selectively position the panels relative to each other allows for greater freedom in the design and configuration of a climbing wall assembly from the various panels 12, and can allow for more efficient use of the space available for the climbing wall. Further, the placement of the hinge members 40a,b also allows for the panels to be flipped or rotated about a horizontal axis, such that the top of the panel becomes the bottom of the panel. The panels can also be rotated about a vertical axis such that the right side of a panel can become the left side of a panel. This ability to change to manner or position in which the panel is installed in a wall assembly increases the freedom in designing the overall configuration of a wall assembly. In addition, because the hinge members 40a,b and the end panel passages 30 enclose the support posts 50, the support posts are contained inside the plastic of the climbing structure. Hence, children climbing on the wall will only come into contact with plastic—they will not come into contact with the metal support post 50. Also, as noted above, by encasing the support posts, the number of foot and hand holds on the individual panels 12 can be increased. The caps 52 and 62 close the openings through which the support posts are passed. This reduces possible areas of entanglement.
As seen in
To assemble a climbing wall structure, the wall structure is first laid out in the area where the wall will be erected. With the proper location for the support posts 50 noted, the appropriate base members are put in place. If an in ground installation is to be used, then base members 80 are used. If a surface installation is to be used, then the base members 80′ are used. After the base members have been positioned and secured in place, the wall panels 12 can be put in place. The base member mounting post has a diameter generally equal to the diameter of the support post, hence the bottom hinge of the panel will slide over the base member mounting post 86, 86′. After two adjacent panels are positioned, with their hinge members aligned with each other and with a mounting post, the support post 50 for the two adjacent panels can be passed through the passage defined by the hinge members of the two panels to be received in the base member mounting post. A fastener 88 will then be inserted to secure the supporting post to the base member mounting post. The structure 10 can be assembled starting from one end and working towards the other, from the middle towards the ends, or in any other desired order. The supporting posts can be put in place as the wall is assembled (i.e., as panels are positioned), or all the panels can be positioned, and then the supporting walls can be put in place. Once the wall assembly has been constructed, the ground G ground cover GC is positioned about the climbing structure. The ground cover GC has a depth sufficient to cover base members and their fasteners 88, and most preferably extends at least from the ground G or surface S to the bottom 21 of the climbing structure, if not slightly above the bottom of the climbing structure. The ground cover can be any acceptable ground cover, such as shredded wood, shredded tires, pea gravel, etc.
As various changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Although the hinge members 40a,b are shown to be approximately the same length, the hinge member 40a can be longer or shorter than the hinge member 40b, as long as the hinge members 40a,b of two adjacent panels will mesh together for form a passage which will surround substantially the entire above ground length of the support post 50. This example is merely illustrative. The connecting elements could be reconfigured such that the wall panels “snap” together. In this instance, a “pin” would be formed into one set of the connecting members and a corresponding opening would be formed in the connecting members of the adjacent panel. The two panels would be “snapped” together and could pivot about the connection between the two panels. The caps 62 would then serve a greater role in connecting adjacent panels together. This would also require that the panels be further secured to a base. This example is merely illustrative.
