This invention is directed to a roller ride, the roller ride being an amusement device whereby persons can enter upon the ride at the higher end thereof and individually ride down to the lower end thereof, the ride eing capable of several embodiments so as to impart different ride impressions.
Slides are well known in the childrens playyard equipment field. Such slides are conventionally straight troughs Which slant downward at a uniform angle so that when a child enters upon the top end he slides down to the bottom. Such slides are primarily effective when the sliding surface is clean and dry so that speed of different sliders is uniform, and none goes too slow or too fast. The angle is arranged so that when in the cleanest condition for the maximum sliding speed, this speed is limited to a reasonable value for safety. Thence, when the slide becomes dirty, sliding virtually stops. While undulation and horizontal curves are occasionally found in such slides, they are difficult to manufacture by reason of the nature of the sliding surface. Thus, such slides are severely limited.
It is an object of this invention to provide a roller ride which provides different ride characteristics from the well known childrens slide and which is arrangeable in a plurality of different configurations for different effects in different environments.
It is a further object of this invention to provide a roller ride which provides riding characteristics which are differcut for different persons riding thereon, so that smaller, lighter persons proceed down the roller slide at a slower rate than heavier persons.
It is another object of this invention to provide a roller ride which is comprised of a large plurality of rollers arranged upon slings so that a rider rolls from one set of rollers to the other while supported by the slings.
It is another object of this invention to provide a roller ride having flexible slings so that the slings can be easily positioned in the roller ride during the building of the structure, and wherein the individual slings can adapt themselves to the various riders.
It is another object of this invention to provide a plurality of rollers on the roller ride sling, which plurality of rollers form into a generally channel shaped configuration so as to provide safe side support to prevent a rider from falling sidewards off of the roller slide, each of the rollers on each sling being rotatable to permit ease of forward, downward motion of the rider.

As an aid to understanding this invention it can be stated in essentially summary form that it is directed to a roller ride. The roller ride comprises first and second side rails, spaced from each other and suitably supported. A plurality of slings connect the side rails. The slings are sufficiently long so as to form a hanging loop. A plurality of rollers are provided on each one of these slings, the rollers being rotatable. The overall angle of the bottom of one sling to the next is generally directed downwardly so that when a person enters upon the uppermost rollers in the uppermost sling, he descends from roller to roller to the outlet of the roller ride. In different embodiments, the side rails can be straight with the slings at substantially uniform lengths so that the roller ride provides a uniform down-hill passage. In other embodiments, the side rails extend downward at a uniform angle, but the slings are of different lengths so that the bottom of the slings defines a curved path. Thus, an undulating ride is obtained. In further embodiments, the side rails can be formed into a vertical curve and provided with uniform length slings so that an undulating ride is formed. In another embodiment the side rails are supported from downwardly sloping ground and are shaped to the ground contour so that a ride generally corresponding to the ground shape is obtained. In a further embodiment, the side rails are bent into circular arcs so that a downwardly spiral path of travel is enjoyed.
Several roller arrangements are possible. In one em bodiment, a relatively thin metallic rod is connected as a hanging loop between the side rails. The rollers are rotatable on this loop. In one embodiment, anti-friction bearings are used for easy rotatability, in another embodiment, sliding bearings are used to provide greater friction to prevent excessive speed. In another embodiment, rollers are connected together by universal joints so as to form a rotatable sling. This sling has a rotating connection with the side rails.
This invention will be understood in greater detail by reference to the following portion of the specification where the drawings are described. FIG. 1 illustrates the preferred embodiment of the roller ride of this invention which is generally indicated therein at 10. The roller side 10 comprises upright posts 12, 14 and 16 which support side rails 18 and 20 through yokes 22, 24 and 26. As is illustrated in FIG. 2, the yokes extend crosswise on the upright posts, then upwardly and then inwardly and are secured to the side rails 18 and 20 to support them in position. As is seen in FIGS. 1 and 2, the side rails come down to the ground at the lower end of the ride 10 for support. Additionally, yoke 22 extends upwardly so as to provide a looped handhold, and extends across above the entry platform to force the riders to be seated upon entering upon the downwardly sloping portion of the ride. Also secured to yoke 22 is ladder 28 which permits the riders to ascend to the entrance to the roller portion of this roller ride.
Protective pan 30 is mounted within yokes 22, 24 and 26 so as to form a protective channel on the sides and the bottom of the roller ride between these points. Furthermore, pan 30 has louvres 32, directed downwardly, to permit sand and debris to exit from the pan. The protective pan prevents mischievous youngsters from inserting objects between the rollers, which action may injure the riders on the roller slide. The lower portion of the roller ride is considered too close to the ground to require such a protective pan, but such could be provided if desired. Furthermore, the pan 30 is preferably applied in all embodiments of the roller ride, even though it is illustrated only in FIGS. 1 and 2 with respect to the roller ride 10. It is omitted from the following embodiments in order to clarify the showings.
It is to be noted that in the embodiment of FIG. 1 the slings carrying the rollers are of uniform length and the side rails 18 and 20 are straight and uniformly downwardly inclined. The slings themselves will be disclosed in further detail in a later portion of this specification. For identification, the slings are indicated at 34.
The second embodiment of this roller ride of this invention is generally indicated in FIG. 3 at 36. The roller ride 36 comprises upright posts 38, 40 and 42 which support a pair of side rails 44 by means of yokes 46, 48 and 50. Furthermore, ladder 52 provides a place to ascend into the top of the roller ride. It is to be noted that the roller ride 38 at it is described, is identical to the roller ride 11). However, in the roller ride 36, the slings 54 are of varying length so as to provide an undulating ride within the confines of the straight side rails 44. Structurally the slings 54 can be identical to the slings 34, except for the overall length of individual slings.
Referring now to FIG. 4, the third embodiment of the roller ride of this invention is generally indicated at 56. The roller ride 56 comprises upright posts 58, 60 and 62 which support a pair of side rails 64 by means of yokes 66, 68 and 70, in an identical manner as indicated with respect to FIG. 1. Furthermore, ladder 72 provides a place to ascend into the top end of the roller ride. Side rails 64 are formed into vertical curves to provide an undulating ride and slings 74, secured to side rail 64 in supporting the rollers thereon, are of uniform length so as to provide an undulating ride. Again, the slings 74 are constructed similarly to slings 34, and are described in more detail below.
Referring to FIG. 5, another embodiment of the roller ride is generally indicated therein at 76. The roller ride 76 illustrates the application of the generic roller ride invention to a downwardly sloping contour. The roller ride 76 is supported on a plurality of upright posts 78, each being surmounted by a yoke 80. The side rails 82 and 84 are supported 'by the yokes 80. Slings 86 are supported by side rails 82 and 84. The slings 86 can be formed in the specific manner as hereinafter described. Furthermore, the slings 86 can either be of uniform length so as to provide a downward ride which conforms to the shape of the side rails or may be of somewhat different lengths so as to provide an undulating ride in specific areas. Furthermore, the height of the upright posts 78 may be varied in accordance with the ground contour so that the downward slope of the ride is appropriate and is only generally related to ground contour rather than exactly related to it. The only requirement is that the exit end of the roller ride 76 be of proper height for convenient entry and for safe exit. The entry end of this roller ride may be just above ground level with an appropriate entrance platform, or may be elevated and provided with a ladder of the type previously described. If desired, a protective pan may be positioned beneath slings and supported upon the yokes 80, in the manner previously described to protect riders upon the roller ride 76.
Referring to FIG. 6, a further embodiment of the roller ride is generally indicated at 88. FIG. 6 is a top plan view of a roller ride having side rails 90 and 92 arranged in partially circular paths. As shown, they extend for threequarters of a circle. In addition, they extend spirally downward so as to provide a circular roller ride. The lower ends 94 of side rails 90 and 92 are sufiiciently close to the ground so that safe exit is permitted. The upper end 96 of the side rails 90 and 92 are elevated and have a ladder 98 connected thereto to permit the rider to ascend to the upper end of the ride. Slings 100 are connected between the side rails 96 and 92. The slings provide rollers upon which the rider descends to roller ride 88.
The particular sling structure useable in any of the roller rides 10, 36, 56, 76 and 88, are described in the FIG- URES 7 through 13. Several different embodiments are disclosed therein, and the difi'erent embodiments can be employed in accordance with particular requirements. Referring particularly to FIGS. 7 and 8, sling 102 is shown as being connected on one end to side rail 104. It is clear that side rail 104 may be any one of the previously described side rails. Side rail 104 is a cylindrical tube and has a plurality of fastening openings located along the lower surface thereof. Only one of such fastening openings is illustrated, but it is understood that there is one of such openings for each end of each of the slings of the roller ride. Slot 106 is wide enough to accept shaft 108. Shaft 168 carries ball 110 on the end thereof, and shaft 108 swaged at 112 to prevent ball 110 from coming oil the end of the shaft. Slot 106 is smaller than ball 110 so that the end of the shaft 198 is retained in side rail 104. Hole 114 is threaded and is open to slot 106. Hole 114 is large enough to pass ball 110 so ball 110 can enter therein and shaft 108 moved into slot 106. Plug 116 is threaded into hole 114 to prevent the end of the shaft from coming out of side rail 104. Each end of shaft 108 is secured to one of the side rails in this manner. Shaft 108 is sufiiciently long and is sutficiently flexible so as to form a U-shaped sling. For example, shaft 108 may be a inch stainless steel rod. The length of shaft 108 depends on whether an undulating ride is desired by different lengths of said shafts and it depends on the amount of U-shape desired between and below the side rails.
Rollers 118 are the preferred embodiment of the rollers mounted upon shaft 108. Rollers 118 comprise a cylindrical tubular center portion 120 secured into roller ends 122 and 124. Roller ends 122 and 124 and tube 120 are preferably of polymer composition material. The polymer composition material need be tough and have low friction and low wear properties. Ends 122 and 124 have large internal bores 126 which permit the shaft 108 to be in curved configuration within the roller. Bearings 128 engage directly upon shaft 108. Bearings 128 are provided with reliefs 130 which reduce the area in contact to permit sand to run out of the end of rollers 118. Furthermore, this reduced area in contact aids in proper hearing characteristics, especially in view of the bent character of shaft 108.
FIGURE 9 illustrates the plurality of rollers 118 on a plurality of shaft 108. The rollers 118 in the lower part of the U-shaped sling are provided with sand outlet holes 132. These sand outlet holes permit the normal soil of a playyard to discharge from the rollers 118. The sand holes 132 are formed in cylindrical tube 120. The sand holes 132 are not necessary in the rollers positioned higher up on the sides of the sling 102, for example as illustrated in FIG. 7, but they may be used there as well if desired.
In order to prevent the slings 102 from moving apart, and perhaps catching the clothing or a bodily member of the person using the roller ride, shafts 108 are interconnected by connecting links 134. The connecting links 134 may be either metallic or polymer composition material and have holes 136 and 138 therein to engage over adjacent shafts 108. Slots 140 and 142 are provided at each of the holes 136 and 138 so that the links may be inserted over the shafts. The link 134 illustrated in FIG. is broken to indicate that various lengths of such a link may be necessary, especially in cases where the side rails are formed in horizontal curves. In such cases, the shafts 108 are further apart at the outer side rail than at the inner side rail, and various lengths of link 134 would be necessary for proper inter-connection.
Another embodiment of rollers is generally indicated at 144. The roller 144 comprises roller tube 146 and bearing balls 148. Roller tube 146 is a relatively large bore tube; equal to about /3 the outside diameter of bearing balls 148. The ends of the tube 146 engage upon the outer surface of balls 148 sufficiently toward the maximum diameter to provide stability. Roller tubes 146 and bearing balls 148 are alternately positioned along shaft 150 to form a complete sling which extends between the side rails. Roller tube 146 is appropriately provided with sand holes 152 to permit the exit of sand therefrom. Bearing balls 148 have large bores 154 entering each end so as to provide a relatively restricted bearing 156. This permits curvature of shaft 150 and reduces the bearing area in contact. Furthermore if desired, the bearing can be formed with reliefs such as the reliefs 130 in FIG. 8. These reliefs would further aid in the discharge of sand and conformation of the bearing to the curvature of the particular shaft 150.
It is noted that the roller structures shown in detail in FIGS. 7 and 11 are sleeve type or sliding type bearings. These bearings have a relatively high coeflicient of friction as compared to rolling type bearings. While roller rides of substantially uniform downward grade can be provided with the same type of hearing, it may be desirable in those with changing slopes to provide bearings of lesser friction in the portions of lesser slope. For this purpose, roller 158, see FIG. 12, is provided with anti-friction bearings. For example, roller 158 has body 160 having a bearing bore therein. Anti-friction bearing 162, which is illustrated as a double-row ball hearing, but may be a single-row ball hearing or an appropriate roller or needle bearing, is mounted within the bearing bore. It is also engaged upon shaft 164 which forms part of a complete sling extending between and secured to the said rails of the roller rod. A plurality of rollers 158 are provided along the length of shaft 164. Seals 166 and 168 are mounted in roller body 160 and engage upon shaft 164 to prevent the entrance of soil into the bearing 162. By this means, individual slings having rollers thereon which roll more easily so as to maintain riders speed can be selectively provided in the roller ride.
It should be noted that in the embodiments of FIGS. 7 and 12, the rollers each rotate on their support shaft independently of the adjacent rollers. Furthermore, a substantial independence of the rollers is provided in the structure of FIG. 11. However, in the embodiment of FIG. 13, the entire rotatable body of sling 166 rotates as a unit. A plurality of rollers 168 are arranged so that a univeral joint 170 is connected between each roller. Roller 168 comprises an outer polymer composition material tube having a metallic tube 172 therein. Universal joints are connected into the rollers and secured into the tube 172. Thus, a string of rollers 168 and universal joints 170 forms the rotatable portion of the sling. The universal joints are of conventional construction, and are illustrated with a flexible covering to prevent dirt from entering therein. There are suflicient rollers 168 and universal joints 170 so as to substantially reach from one side rail to the other of the roller ride in which they are mounted.
One side rail is illustrated at 174, and again is useable in the same embodiments as side rail 104. Side rail 174 also has a slot 176 therein joining with plugged hole 178 which provides for entry and retention of ball 180. Ball 180 is secured to hearing housing 182. Universal joint 186 carries shaft 188 which extends into bearing housing 182 and terminates in flange 190 which bears on bearing 184.
Thus, the entire sling 166 is flexible along its length through the universal joints and 186 and is flexibly connected to side rail 174. Furthermore, the portion of this sling from hearing 184 through the universal joints and rollers to the similar bearing on the opposite end is secured to the opposite side rail and is rotatable. Thus, another embodiment of sling is useful in the roller ride of this invention.
Flexibility of the slings has been described with respect to the several embodiments. From these descriptions, it is clear that flexibility as viewed in the transverse cross section is the flexibility desired. This flexibility permits each individual sling to at least partially accommodate to the load of a person riding along from sling to sling to at least partially shape the sling to the person. Flexibility longitudinally of the ride is undesired, for it would permit sling separation in the longitudinal direction. Such would be uncomfortable, and would present the danger of catching a limb or clothing. Flexibility on the longitudinal direction may be minimized or limited by a number of different types of construction including the links 134.
A definite use advantage of the roller ride of this invention is not immediately apparent from the constructional details recited above. This advantage is that smaller, lighter riders proceed more slowly down the roller ride than heavier riders. Thus, smaller children descend more slowly and safely, in view of the their age, than larger children. The cause of this functional advantage is that the momentum of a lighter child is less, and part of this momentum is consumed in accelerating the rollers on eah sling as they are reached. This is a very desirable builtin safety feature.
This invention having been described in its preferred embodiment, and several additional embodiments disclosed, it is clear that this invention is susceptible to numerous changes and embodiments within the scope of this invention and without the exercise of the inventive faculty.
