ADJUSTABLE CHILD'S SLIDE med May 27 1984 z sheets-sheet z United States Patent O A 3,263,994 ADJUSTABLE CHILIYS SLIDE Richard E. Londgren, 3101 N. 29th, Tacoma, Wash. 98407 Filed May 27, 1964, Ser. No. 370,426 4 Claims. (Cl. 272-56.5)
This invention relates to .amusement and exercise devices for children, with particular reference to an apparatus upon which children can climb 'and slide.
The principal object of this invention is to provide -an unusual climbing and sliding surface for children of many ages. Because the angle of the sliding and climbing surface can be adjusted, this invention is suitable for children from 11/2 years old to 12 years old or older. When the slide pitch is made steeper for larger chlidren, the grab barat the top raises to accommodate the larger children.
Another object of this invention is to provide a double climbing and sliding surface. Because of the unusual features of this invention, a child can climb to the top of the slide, grasp the bar at the top and either slide down the other side or turn around and slide down the same side he climbed up. Because this apparatus has two climbing and sliding surfaces, several children can be Climbing and sliding at the same time.
Still another object of this invention is to provide a slide that can be moved about easily on a playground.
Because this slide has Wheels at one end, it oan be lifted I at the other end and readily pushed or pulled.
Another object of this invention is safety for children using the slide. Because the angle of the sliding and climbing surface can be adjusted to suit the age of the children using the slide, the 'slide is safer than other slides for small children. Also, because of its wide base, the device will not overturn easily. A child cannot fall between the steps on this slide because the steps are relatively small holes in a large flat panel.
An additional object of this invention is to provide a large amusement device that can be stored easily. After removal of four bolts and one p-in, the two sides of the slide can be stored 'as nearly flat panels.
Other objects and advantages will become .apparent by reference to the following detailed description in conjunction with the drawings.
In the drawings:
FIG. 1 is a perspective view of the children's adjustable and movable slide;
FIG. 2 is a fragmentary side elevation of the device supporting the gr-ab bar at the top of the slide;
FIG. 3 is a fragmentary side elevation of the wheel section of the slide.
Similar numerals refer to similar parts in the Various views.
This adjustable slide as shown in FIG. 1 is made of three basic components: a pair of climbing |and sliding panels 1, a pair of angle adjustment bars 2 and a grab bar 3 at the top.
Each clirnbing and sliding panel 1 is made of tempered hardboard o-r other smooth-surface, weather-resistant material. Holes 4 for children to place their hands and feet in as they climb :are cut into each panel 1. The pieces 5 cut from the panels 1 are glued to the underside 6 of each panel 1 to give additional strength at the bottom edge of each hole 4.
Each panel 1 is supported by wooden side rails 7. Each side edge of the panel 1 is glued in a groove 8 cut the length of the side rail 7. All four side rails 3,263,994 Patented August 2,' 1966 ICC.
7 of the slide are identical except the bottom ends of two of the side r'ails 7 have wheel units 9 attached.
Also supporting each panel 1 are three cross braces '10, one brace 10 at each end of the panel 1 and one brace 10 at the middle of the panel 1. Each cross brace 10 is glued to the underside 6 of the panel 1 and nailed 11 to the side rails 7.
The t'wo climbing and sliding panels 1 are fastened to each other by bolting 12 side rails 7 pivotally together slightly beyond the tops of the panels 1.
Two identical telescoping metal tubular braces 13 maintain the angle of the climbing and sliding panels 1. The braces 13 are secured to the side rails 7 with bolts 14. The angle of the slide can be changed by removin-g the bolt 15 in each of the telescoping braces 13, aligning the hole 16 in the larger-diameter section of the brace 17 with another of the holes 18 in the other part of the brace 19 and repl'acing the bolt 15.
FIG. 2 shows the grab bar 3 at the top of the slide. Children, when they reach the top of the slide, can hold onto this bar 3 .as they go under or over to the other side |of the slide or as they move along the top of the slide to go down the same side. When the pitch of the climbing and sliding panels 1 is made steeper, the height of the grab bar 3 increases to accommodate larger children. When the pitch is `adjusted the other way, the grab bar 3 is in a lower position for smaller children. Four identical members 20 are fastened with bolts 21 at the top ends of the side rails 7 to support the grab bar 3. The grab bar 3 extends through holes 22 in the members 20 vand is secured by p-ins 23 at each end of the bar 3.
FIG. 3 shows the wheel units 9 fastened .at the bottom ends of two of the side rails 7. With these wheel units 9 at one end of the slide, a person can lift the othe'r end of the slide and push or pull the entire slide. The wheel 24 is fastened to a side rail 7 .and another support 25 by a bolt 26. The other end of the support 25 is fastened to the side rail 7 and a spacer 27 by another bolt 28.
This children's adjustable slide can be easily disassembled for storage as two practically flat units. To do this, a pin 23 is removed from the grab ba'r 3 and the grab bar 3 is removed from its supports 20. The bolts 15 in the telescoping braces 1'3 are removed and the bolts 12 near the top of the panels 1 are also removed. The brace parts 17, 19 .and the grab bar supports 20 fold against the panels 1. The two panel Sections can then be leaned against a wall or laid down for storage.
Various changes can be made in this invention without departing from the spirit of the invention, .and it is requested that the description of the invention be considered illustrative rather than restrictive.
1. An adjustable slide, comprising: a pair of slide units each provided with a smooth flat panel having a plurality of openings formed therein wi-th side rails and cross braces fixed to each of said panels; means pivotally connecting said slide units together at one end thereof; telescoping braces connected to the side rails of said slide units adjustable to vary the steepness of said slide units; a grab bar supported adjacent the pivotal connection between said slide units; and a parallelogram support means for said grab bar that changes the height of said grab bar when the steepness of said slide units is varied.
2. An adjustable slide in -accordance with cl-aim 1 wherein said pivotal connection means between said slide units is removable.
3. An adjustable slide in accordanee with claim 1 wheien the material removed from said panels to form said openings t-herein is adhered to the underside of each of said panels ot provide additional support for said panels.
4. An adjustable slide in accordance with clairn 1 Wherein wheel means are mounted on the end of one of said slide units opposite the end pivotally connecting said slide units together.
