COLLAPSIBLE SAWHORSE Filed April 26, 1965 IWAIIIIIIIIIAIIIOA "2c INVENTOR.

TTR/VEY United States Patent O 3,276,545 COLLAISlBLE SAWHORSE Donaid DAngelo, 1688 E. 46th St., Brooklyn, NX. Filed Apr. 26, 1965, Ser. No. 450,815 9 Claims. (Cl. 1132-153) This invention relates generally to support means of the type often referred to as trestles or sawhorses.

It is an important object of the present invention to provide a sawhorse-type support which is conveniently collapsible and erectable for i-mmediate use when desired, and for storage in a minimum of space.

It is a further object of the present invention to provide a sawhorse structure of the type described which is of extremely lightweight and durable construction for ease in handling throughout a long useful life.

It is another `object of the present invention to provide a sawhorse construction having the advantageous characteristics mentioned in the preceding paragraphs which is extremely simple in structure, entirely reliable in operation, and which can be economically manufactured for sale at a .reasonable price.

Other objects of the present invention will become apparent upon reading the following specification and `referring to the accompanying drawings, which form a material part f this disclosure.

The invention :accordingly consists in the features of construction, combinations of elements, and arrangements of parts, which will be exemplified in the construction hereinafter described, and of which the scope will be indicated by the appended claims.

FIGURE 5 is a sectional view taken generally along the line 5-5 of FIGURE l.

FIGURE 6 is a top perspective view similar to FIG- URE l, showing a slightly modied embodiment.

FIGURE 7 is an end elevational View showing a sawhorse support of FIGURE 1 in erected condition standing upon a ground surface.

FIGURE 8 is a sectional elevational View showing the sawhorse of the present invention in operative association with a supported bed member or table plate.

Referring now more particularly to the drawings, and specifically to FIGURES 1 5 thereof, a sawhorse-'type support of the present invention is generally designated 10, and includes a pair of generally yoke-shaped members 11, which may advantageously be fabricated of round tubular stock.

Each yoke-shaped member 11 includes a generally straight bight portion 12 and a pair of legs 13 extending transversely from opposite ends of `the bight portion. In practice, the `leg portions 13 may be integral with and connected by bends 14 to the bight portions 12, the legs of each yoke-shaped member 11 extending in substantially parallel relation with each other.

If desired, the bight portions 12 may each be of a sectional construction, say including a pair of

sections

15 and 16. Each section 15 may include a male extension 17 insertible into the adjacent end of a section 16 for detachable end-to-end securement of bight-portion sections in end-to-end aligned relation.

Patented Oct. 4, 1966 In the assembled relation of yoke-shaped members 11, their bight portions 21 extend in adjacent, spaced parallelism with each other, and are formed on their adjacent sides ywith pairs of facing openings, as at 20, best seen in FIGURE 3. Interposed between the adjacent spaced bight portions 12, and specically between the openings 20 of each facing pair, is a spacer member or washer 21, which may be fabricated of rubber or other suitable material. A tie member or pin 22 extends in spaced relation through each facing pair of openings Ztl, and closely through the intermediate spacer or washer 21, see FIG- URE 3. Opposite ends of each transverse pin 22 may be secured to the outer sides of respective bight portions 12, advantageously by a swingable connection, such as the rounded heads 23.

In this manner, the bight portions 11 are connected together in their spaced lparallel relation and relatively rotatable about longitudinal axes. That is, the swingable end `connections of the pins 22 with the outer sides of bight portions 12, as by the headed pin ends 23, enables the bight portions to rotate about longitudinal axes relative to each other with each pin 22 moving relatively downward in the facing pairs of openings 20 from the position shown in FIGURE 3.

Upon this relative rotation of bight portions 12, the leg portions 13 of each adjacent pair are swingable toward and away from each other to effect collapse and erection of the sawhorse 10. The swinging movement of legs 13 away Ifrom each other is limited by interconnected linkages 25 between each pair of adjacent leg portions. Each linkage 25 includes a pair of links 26 pivotally 4connected together at their adjacent ends by a pin 27, and having their distal ends respectively pivoted t-o adjacent leg portions 13 by pins 28. Upon swingly movement of the legs 13 of each adjacent pair toward each other to the collapsed position of FIGURE 2, the links 26 are relatively swingable to the position shown.

Each leg 13 may also be of sectional construction, as best seen in FIGURE 5. Each leg portion may include an upper tubular section 30 integral with the adjacent region of the associated bight portion 12, and a 4lower section 31 telescopically received in the lower end of the upper section 30. A catch 32 of any suitable construction may be employed to releasably retain the lower section 31 in a selected position of its extensile and retractile movement relative to the upper section 30. `The catch 32 may include an arm 33 pivoted intermediate its ends, as by pin 34 to the section 30 and having a transverse end extension 35 removably engageable through the leg section 34) and a selected aperture 36 of the leg section 31 to vlock the Aleg sections in any desired relationship. Resilient means 37 may be employed to releasably retain the catch 32 with its extension 35 engaged through a selected hole 36. Of course, the arm 33 may be manually swung to remove the extension 35 for longitudinal shifting of the lower leg section 31. In this manner, the height and inclination of the sawhorse 10 may be selectively adjusted as required by the intended purpose or supporting ground surface, and the leg section 31 may be stored entirely within the leg section 3G.

In the embodiment of FIGURE 6, there is shown a sawhorse type support generally designated 10a, wherein each yoke-shaped member 11a is integrally fabricated of a single length of tube stock. Thus, the parallel bight portions 12a of each yoke member 11a are of integral construction and integral with the transverse leg portions 13a. The parallel bight portions 12a are connected together by suitable pins 22a, which may be of the same construction as shown in FIGURE 3, and the leg portions 13a are connected together by limiting linkages 25a, which may be the same as shown in FIGURE 1.

Thus, the sawho-rse construction a of FIGURE 6 is in many respects identical to that of FIGURES l-S, but may may be :more economical in cost at the sacrifice of some adjustabilty and space savings in storage.

In FIGURE 7 is shown a further embodiment wherein leg portions 13b, corresponding to the

leg portions

13 and 13a described hereinbefore, have their lower ends each cut obliquely to the axis of the respective leg portion, so as to be substantially parallel to a generally horizontal ground or supporting surface in the erected condition. Adv-antageously, the lower ends 40 of the leg portions 13b may be provided with protective plugs 41 of rubber, or other suitable frictional material.

In the further embodiment of FIGURE 8, there is shown a sawhorse-type support 10c having yoke-shaped members 11C which may be substantially identical to the previously described yoke-shaped members 1I, or those designated 11a.

The yoke-shaped members 11e include parallel, spaced bight portions 12C, which may `be connected together in spaced relation, `as in FIGURE 3, for relative rotation about longitudinal axes.

Associated wit-h and resting on the bight portions 12C of sawhorse 10c may be :a table plate or bed member 45. In order to securely anchor the bed member in position on the sawhorse 10c, fastener means 46 may extend through the space between the bight portions 12e having its lower end enlarged and its upper end secured to the bed member. More particularly, a fastener or bolt 47 m-ay extend through the space between bight portions 12C having its upper end enlarged, as by a head 48 for securement to the bed member 45. The lower end of the fastener 47 may be provided with `an enlargement or washer 49 below the bight portions 12e and a nut 50 threadedly engaged on the fastener to draw the washer 49 in firm abutting engagement with the undersides of the bight portions. In this manner, the bed member or table plate 45 may be securely fastened in position on one or more sawhorse supports 10c, and quickly removed therefrom by removal of the fastener 47 from between the bight portions 12C.

From the foregoing, it is seen that the present invention provides a sawhorse-type support which fully accomplishes its intended objects and is well adapted to meet practical conditions of manufacture and use.

Although the present invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be made within the spirit of the invention and scope of the appended claims.
