3 Claims. Cl. 280-41) The present invention relates to stands and more particula'rly to a stand for supporting articles which is portable, collapsible and mobile.

In the masonry trade it is standard practice to provide support for a mortar board and devices for such a purpose are appropriately known in the art as mortar board stands. In use, a mortar board is normally loaded with mortar and then rested on a stand at a convenient height above the floor or ground to facilitate access to the mortar for application to building walls, ceilings and the like by a mason or other Worker.

In the past mortar board stands have assumed numerous forms. An early type consisted of an upstanding, generally rectangular wooden frame on which a mortar board was rested. These frames were bulky, not collapsible, difficult to store and transport, and not mobile. Later developments include elongated sets of legs pivotally connected in X shape, and rectangular frames likewise connected in an X configuration pivotally joined for opening and folding. These frames are ordinarily held against collapse in their open or erected positions by chains or like members. Although the latter stands are portable and collapsible, they are not mobile and in some instances of inadequate durability to perform their intended functions.

Mobility has been found to be a highly desirable characteristic in a mortar board stand. While plastering a wall or ceiling of a large room, for example, it has often been necessary, with conventional mortar board stands which are not mobile, to walk back and forth repeatedly from the stands to the areas of application of the mortar in order to obtain fresh amounts of mortar as required. This obviously results in much delay, inconvenience and consequent expense. Of course, stands of the prior art could be moved but generally only by first removing the mortar board supported thereon and then picking the stand up and placing it in a new location whereupon the mortar board was again positioned thereon. Such a procedure is time consuming, ineflicient, clumsy and subject to the spilling of mortar.

Although the invention is described for use in supporting a mortar board and is excellently suited for such a purpose, it will be evident as the description proceeds that the disclosed stand is adapted to support a variety of articles and is not necessarily limited to the use which motivated its development.

Accordingly, an object of the present invention is to provide a supporting stand which is mobile, portable, and collapsible.

Another object is to provide an article supporting stand which may be collapsed into compact form for easy handling, storing and transporting.

Another object is to provide a stand for supporting large and bulky materials of considerable Weight which is easily moved notwithstanding the positioning of such articles or materials thereon.

Another object is to provide a lightweight stand of the character described which is durable and especially capa- 2 ble of withstanding strain and dependably supporting heavy loads thereon.

Another object is to save time, labor and expense in the masonry art by providing an improved mortar board stand.

Another object is to provide a mortar board stand which enables the easy loading of a mortar board positioned thereon and movement thereof, as desired, to the exact location of application of mortar and the like in building construction.

Another object is to provide a stand of the character described which is simple and economical to make and use, light in weight, adapted to many uses, and which is highly effective in performing its intended functions.

These and other objects will become more fully apparent upon reference to the following description.

Referring with greater particularity to the drawings:

A stand constructed in accordance with the present invention is shown in the drawings as including a rigid, substantially rectangular open main frame 11 having an upper end 12 and a lower end '13. The main frame includes a pair of spaced parallel longitudinal bars 14 extended between the upper and lower ends of the frame, an upper transverse bar 15 interconnecting the upper ends of the longitudinal bars, and a lower transverse bar 16 interconnecting the lower ends of the longitudinal bars. The bars are preferably of hollow tubular metallic construction of considerable rigidity but relatively light in weight. The lower bar 16 may be omitted, if preferred.

Stub axles 20 extend axially endwardly of the lower transverse bar 16 and support wheels 21 are journalled thereon. The support wheels are preferably but not necessarily rubber tired and are releasably held on the axles by cotter pins 22.

A rigid substantially rectangular open auxiliary frame 26, preferably of the same material as the main frame 11, also has an upper end 27 and a lower end 28. The auxiliary frame provides a pair of spaced longitudinal bars 29 extended between the upper and the lower ends of the frame terminating in angularly extended foot portions 30 at the lower ends thereof. An upper transverse bar 31 interconnects the upper ends of the longitudinal bars 29, and a lower transverse bar 32 interconnects the longitudinal bars adjacent to the lower ends thereof but spaced upwardly somewhat from the foot portions. The lower transverse bar thus imparts needed rigidity to the auxiliary frame at its lower end. In addition, a pair of resilient latches 33 extend outwardly from the bars 29 adjacent to the lower transverse bar 32 for purposes which will soon be described.

The main frame 11 and the auxiliary frame 26 are interconnecited by a pivot rod 35 extended through the longitudinal '

bars

14 and 29 intermediate their opposite ends to enable pivotal movement of the frames between.

an open, extended orer'ect' position such as shown in Fig. 1, and a collapsed or folded position, such asshown' inlliig. 7 ;,Obviously, any other arrangement than thergd 35 maybe providedrto' pivotally interconnect the frames;

:The frames are thus connected in the general shape of an uprightlX and when erect the foot portions 30 of the auxiliary frame 26 are adapted to be'in' substantially perpendicular relation to any support surface on which the stand 10 rests. Further, in the. erect position of the' frames, the auxiliary frame is forwardly inclined at about a 45 angle, and the main frame is rearwardly inclinedat about'a 45 angle; These angular dispositions are by no means critical but serve to illustrate more specifically the described embodiment of the stand.

The upper transverse bar 31 of the auxiliary frame 26 provides a bore 40..centrally transversely extended therethrough and adapted to be disposed inan erect position when the stand 10 is erect, as in Fig. l. A U-shaped plate constituting a brace receptacle is mounted, as

shown in Fig. 5, on the upper transverse bar -31below the bore 40. VA bearing collar 42 isrotatably mounted on flie upper transverse bar of the. main frame 11 and 7, shown in Fig. 1. The bra'ce44 is pivoted upwardly and the extended end,46 thereof. slidably fitted, intothe brace receptacle 41. With' the aperture 47 in the brace in registration with the bore 40, the loci; pin 50 is dropped through the bore and the aperture. This locks the frame in an erect position." a

is maintained against axial sliding movement in a central position on the bar 15, by bosses'43 extended from the bar '15 atboth ends of the collar. 7 An elongated rigid H brace 44 of rectangular cross section provides an' inner or rearward end 45 secured to the bearing collar 42 and 7 an extended or forward end 46 providing an aperture 47 therein. It is to be noted that the brace is slightly longer than the distance between the upper

transverse bars

15 and 31 when frames Hand 26 are in the desired erect position so that the extended end 46 may be slidably fitted in the brace receptacle'41.

A lock pin 50 is adapted to-be releasably slidably received through the bore 40 and aperture 47 in the brace 44, when the latter'is in the brace receptacle 41, and is conveniently connected to the uppertransverse bar 31 by means of a flexible chain 51, as best seen 4 and 5, to prevent loss thereof.

A pair of elongated handle bars 55 provide inner or forward ends 56 on which are mounted sleeve bearings 57 journalled on the upper transverse bar 31 of the auxiliary frame 36. 'The handle bars also have extended outer or rearward ends 58 disposed for gripping convenience. A transverse bar 59 interconnects the handle bars intermediate their ends and in a position spaced from their inner ends a distance substantially equalto the distance between the upper

transverse bars

15 and 31 when the

frames

11 and 26 are erect and the pin 50 is extended through bore 40 and aperture 47.

The handle bars 55 are thus adapted for pivotal movement between a position folded or rested against the auxiliary frame 26 and a substantially horizontal position extended through the main frame 11 and beneath the up- 7 per transverse bar 15. In this latter position the transverse bar 59 interconnecting the handle bars lies immediately beneath the upper transverse bar 15. V

A latch sleeve or receiver 65 is mounted o'n'the hearing collar 42 generally diametrically opposite to the brace 44. A pair of U-shaped latch straps 66 are mounted in spaced axially aligned positions on the transverse bar 59 which connects the handle bars 55'and in positions adin Figs.

The handle bars 55 .are then pivoted upwardly into substantially horizontal positions and the .latch bolt 67 pulled back, if necessary, and then pushed forwardly to insert the locking finger into the latch sleeve 65. This locks the. handle bars into theirupper positions with the outer "ends 58 extended rearwardly beyond the upper transverse bar 15 of the'main frame 11'.- v

In use, a mortar board, or the like, indicated in outline by the dashed lines at 75', is positioned onthejst'and 10, being rested on-theupper ends 12 and 27 of theframes,

11 and 26. It will be noted that the periphery of the board mayoverhang the transverse bars and thehandle bars 55 a considerable distance, if desired. The'handle. bars are made suificiently long to enable convenient and,

adequate grasping area so that large and bulliy items may be supported without interfering with the maneuverability of the stand.

I; is next desirable to load the board 'l s'lwinimeria f or the like. This is easily done by grasping the' handle" it may be moved on the stand to'any desired location where the mortar is tobe applied. 7 The lengthy handle.

bars not only clear the mortar board but offer a decided mechanical advantage in the leverage afforded Atjthe desired location; the foot portions 30 maintaimthemortarl board in substantially horizontalposition. and hold 'the stand stationary. It will be evident that the incorpora: tion in the stand of the brace 44 and the handle bars155 imparts extra durability to the stand for dependab y supwardly against the auxiliaryframe26y It is to be noted at board is positioned on the stand. Such would be. desirable when working in a limited space or when desiring to move with greater ease around the mortar boardQ-Of course, the brace 44 maintainsthe frames 11 and 26 in dependable erect positions notwithstanding the release of the handle bars into folded condition.

Assuming, however, that the'sta'nd10- is to becom- .pletely collapsed, the lock pin is next-removed from the bore 40 and "aperture 47 to permit the brace 44 to be removed from the brace receptacle 41. With the brace thus removed, it pivots downwardly on the bearing col lar 42 and enables folding of theiframes "11"and2 6 .into closed position, as shown in Figs. 6 and'7.

In its collapsed condition, the stand is easily carried,

stacked, transported and stored. Additionally, the stand 7 may be drawn, pulled or pushed on thesupport wheels"21' ja'cent to the latchsleeve when the transverse bar 59'isv sub-adjacent to the transverse bar 15. A latch bolt 67 is slidably fitted in the straps 66 and includes a locking finger 63 ada ted to be releasablyslidably' extended into by grasping the upper transverse bars. 15 and'31; ,7 Further, the stand -10 is adapted'to 'be supported on a scaffold, or the like, not shown, if desired,"'ratherthan on the floor or ground. For this purpose, .the' handles-55 are dropped againstthe. auxiliary frame and arenas in place by latches 33whichspread outwardly and resiliently latch over the handles. The stand is then rested in inverted position on the scaffold with the wheels'jl.

upwardly disposed. A mortar board, as 75', may then be supported on the wheels and the foot portions in a convenient manner.

From the foregoing it will be apparent that a support stand has been provided which is mobile, sturdy and durable but which is easily collapsed for storage and transport. The stand is easily manipulated, and excellently suited for handling bulky, heavy objects. It has been found to result in savings of time, labor and effort in applying mortar and the like in its use as a mortar board stand. As explained, it will be evident that the invention has many other uses although excellently suited for the described purposes.

Although the invention has been herein shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to 'be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus.
