SHEET 3 BF 3 Howard 6. Lang/rausen POOL TABLE DOLLIE The invention herein is generally concerned with the provision of a device whereby one man can load and transport pool tables and the like. More particularly, the instant invention relates to a hand-propelled dollie which receives a vertically tipped pool table, providing opposed table bracing upright portions and a mobile base for manual movement of the supported table as desired.

Significant objects of the invention include the provision of a dollie which incorporates laterally adjustable sections for the accommodation of tables of different depths, and auxiliary support and rocker arms for facilitating both a loading of the table onto the dollie and a subsequent setting up of the dollie in a usable horizontal position.

Other objects of the invention include the provision of a dollie which, when not in use, collapses into a pair of separate compact sections which are easily carried or stored; a dollie which is of a structurally simple although highly unique and stable construction; and a dollie which is easily used both as a transporting means for the table and as a device for facilitating the erection of the table.

Basically, the objects of the instant invention are achieved through the provision of a two-section dollie. Each section mounts a pair of transport wheels with a first section including laterally extendable cradle arms selectively locked to the second section in a manner which enables a lateral adjustment of the sections relative to each other for an accommodation of tables of different depths. The first section includes pivotally mounted support leg means for an angular support of the loaded cradle, while the other section is adapted to selectively mount rocker means utilized in swinging the dollie, and the supported table, to a horizontal position.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIG. 8 is a perspective detail illustrating the manner of mounting the lower end of one of the rocker arms.

Referring now more specifically to the drawings, reference numeral 10 is used to generally designate the dollie comprising the instant invention. The dollie 10 consists basically of two

similar sections

12 and 14.

The section 12 includes an elongated rectangular base 16 formed of laterally spaced horizontal rails l8 interconnected, at the opposed ends thereof, by transverse bars or plates 20 to define a rigid rectangular framework. The base 16 is mobile, mounting a pair of spaced aligned freely rolling wheels or rollers 22 located inwardly of the opposed end cross bars 20.

A table stabilizing upright portion 24 mounts on the inner rail 18 and extends a substantial height vertically therefrom. This upright portion 24 consists basically of a pair of laterally spaced side posts 26 interconnected by upper and intermediate cross rails 28. The upright portion 24 is braced by a pair of braces or legs 30, one fixed to each post 26 at or slightly above mid-height thereon and extending downwardly and outwardly therefrom to fixed engagement with the outermost of the base rails 18. The innerfaces of the vertically elongated support portion 24 can be cushioned as desired so as to provide for a non-marring engagement with a received pool table or the like.

The second section, section 14 includes all of the above described components which, in the drawings, have been designated by like reference numerals.

The two

sections

12 and 14 are, during use, releasably interconnected by a cradle consisting of two cradle arms 32, each being in the nature of an elongated angle bar including a horizontal top flange 34 and a depending vertical flange 36. The inner base rail 18 of section 12 includes an elongated rod 38 extending completely therethrough and beyond the opposite ends thereof so as to pivotally mount the opposed cradle arms 32 to the opposite ends of the base 16, the rod end portions extending through the vertical flanges 36 slightly inward from the end thereof. Mounted in this manner, the cradle arms 36 can pivot between a stored substantially vertical position as in FIG. 7 and a horizontal in use position as illustrated in FIG. 1.

In order to maintain each cradle arm 32 so that it projects perpendicularly from the associated upright portion 24, independently of the second section 14, a rotating lock or retainer 40 is provided and orientated so as to selectively engage beneath the extreme end of the horizontal flange 34 of the arm when the arm is rotated to its horizontal position. This retainer, noting particularly FIGS. 5 and 7, consists of a vertical rod rotatably retained within a horizontal plate 42 projecting from the end of the associated base 16, the rod having a laterally directed lower end portion which can be selectively swung under or away from the end portion of the top flange 34. When swung beneath the top flange 34, as illustrated in FIG. 5, the top flange is retained between the rod end and plate 42 and hence locked in at the horizontal position thereof.

In order to provide for an interlocking of the sections 12 and I4 through the cradle arms 32, the vertical flange 36 of each cradle arm, toward the outer or free end thereof, includes a series of vertical slots 44 therein. These slots selectively engage over and receive an outwardly directed vertical plate or keeper 46 projecting from the corresponding end of the base 16 of the second section 14. Each of the plates 46, noting FIGS. 6 and 7 in particular, have the end portion thereof laterally bent so as to lie parallel to and immediately outward of the vertical flange 36 of the associated cradle arm 32 thereby precluding an accidental disengagement of the arm 32 from the plate 46. As previously indicated, the provision of a series of retaining slots 44 enable an adjustment of the lateral distance between the

sections

12 and 14 as well as a positive interlocking of the sections to each other in any of the adjusted positions thereof. In this manner, pool tables and the like of varying depths can be accommodated in a snug and protected manner. The upper surfaces of the cradle arms 32 will also of course have protective or cushioning material provided thereon.

In order to further assist in positively interlocking each cradle arm 32, an elongated spring loaded lock rod 48 is provided in conjunction therewith. This rod 48 overlies the inner base rail 18 of the section 14 and is slideably extensible through the lower end portion of an adjoinging vertical post 26 as well as a vertical plate 50 mounted inwardly thereof. The rod 48 is biased outwardly relative to the post 36 by a coil compression spring 52 engaged between the mounting plate 56 and a collar 54 on the rod 48. The lock rod 48, when extended through the biasing action of the spring 52, lies over the adjoining engaged cradle arm 32 as will be best appreciated from FIG. 6. In order to retain the rod 48 in a retracted position, for ease of positioning of the associated cradle arm 32, the mounting plate 50 associated therewith is provided with an inwardly directed flange behind which the laterally directed end 56 of the rod 48 can engage upon a retraction and rotation of the rod. This feature will be best appreciated from FIG. 7.

The section 12 is also provided with a support unit 58 consisting of a pair of laterally spaced support legs 60, each hingedly connected to one of the crossbeams 28 located slightly above mid-height on the upright portion 24. These legs include enlarged stabilizing feet 62 on the lower ends thereof and are transversely braced relative to each other by a cross member or beam 64.

An appropriate over center pair of lock arms 66 extend a between the leg brace 64 and one of the crossbeams of the upright portion 24 for both locking the support unit closely against the section as illustrated in full lines in FIG. 2 and at an outwardly inclined position relative thereto as illustrated in phantom lines in H6. 2. The extended position of the leg unit 58 enables a convenient angular tipping of the section 12 with or without a load thereon. This in turn facilitates an assembly of the second section 14 thereto. This feature, in conjunction with the ability to stabilize the cradle arms 32 independently of the second section 14 allows a single person to easily load a table on the extended cradle arms 32, tip the section 12 outwardly onto the leg unit 58 and subsequently mount the second section 14 so as to snugly engage the mounted table for transport thereof on the now completely formed dollie and the four traveling rollers provided thereon.

' The unloading of the table or the like 30, even subsequent to the positioning of leg mounted levelers 68 thereon, taking advantage of the exposed orientation of the table legs, is easily effected through the provision of a rocker 70 removably mounted on the outer side of the section 14. This rocker 70 includes a pair of laterally spaced vertically arcuate and outwardly convex arms 72, one aligned with each of the upright posts 26 of the section 14. The upper end of each of the rocker arms 70 includes a vertically turned portion 74 which is slideably received through a postmounted collar 76. Each arm 72 sweeps arcuately to a point in spaced relation below the end of the base and then turns vertically, as at 78, and then horizontally, as at 80, for introduction through a depending collar 82 fixed to the base end. Each rocker arm 72 can thus be mounted through a combined swinging and sliding movement thereof so as to engage the opposed ends through the pair of section mounted

collars

76 and 82. If deemed desirable for additional stability, a reinforcing plate 84 can be welded within the lower portion of each arm 72. It will be noted that the support unit 58 is utilized to stabilize the dollie 10 in a slightly tipped position so as to enable a mounting of the rocker 70. Further, it will be noted that the lower end of each arcuate arm 72 is positioned slightly inward of the wheels 22 of the section 14 so as to facilitate a direct movement of the table supporting dollie 10 onto the rocker arms as the dollie and table are swung to a horizontal position. Once horizontally orientated, the table 30 and dollie 10 can be easily disengaged with the slightly elevated portion of the table 30 brought downward upon a removal of the dollie. Incidentally, it will be noted that the arcuate sweep of the rocker arms 72 is sufficient so as to outwardly span the lower set of table legs to avoid damage thereto upon movement of the table to the horizontal position.

From the foregoing, it will be appreciated that a highly unique table transporting and positioning dollie has been defined. The dollie, while capable of forming a highly stable support and transport vehicle for large and extremely cumbersome pool tables and the like, is by the same token easily collapsed into two compact sections. The assembled dollie includes a support unit enabling a tipping of the dollie to a stable inclined position as well as a rocker unit which enables a swinging of the dollie and carried table from a vertical to horizontal unloading position.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resort to, falling with the scope of the invention.
