Abstract

A device to form a staging on a base such as the ground comprising a single upright support, a looplike member to embrace said upright support with arms on said member extending generally horizontally laterally from the upright support for engagement with a wall of a building to provide between the upright support and the building a rest for the formation of a platform.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1 I have shown the side 10 ofa house with an uneven supporting surface 11 of ground adjacent to the wall 10 of the house. Two uprights l2 and 14 are shown in spaced relation which may be of any height, and the device which is the form of the invention is designated as 15 located upon these uprights and supporting a plank 16 between the devices 15.

The device designated generally 15 comprises a member 20 of generally looplike form, in this case being shown generally rectangular so as to embrace the generally rectangular upright support either 12 or 14. Arms 21 and 22 are secured such as by welding 23 along opposite sides 24 and 25 of the looplike member 20 and flare outwardly therefrom and are provided with ends 26 which will engage the wall of the building such as shown in FIG. 1. In some cases a bar 27 (FIG. 5)'may extend between these ends to provide a broader support and prevent the arms 21 from spreading to a greater angular relation, The plane ofthe arms 21 and 22 forms an obtuse angle 30 between the upright 12 and the plane of the arms 21, 22, thus giving some angularity to the upright support 12 with relation to the wall of the house. The end of this support 12 may be of any form, that being designated in this case as 31, so as to get a good grip on the ground 11, or it may be pointed to extend somewhat into the ground. The loop 20 is angled in accordance with the angularity 30 desired for the relationship between the upright support 12 and the plane of the arms as may be seen in the side view of FIG. 2, and the relationship between the embracing looplike member 20 is such that there will be broad flat surfaces 33, 34 on the inside of the loop to engage and slide along the support 12. However, when the plank such as 16 is placed upon the horizontal rest 21, 22 provided by the arms, there will be a sufficient weight upon these arms so as to tend to swing the ends of the arms adjacent the building downwardly, causing the inner surface of the portion 33 of the loop to dig into the upright support 12 at 36 which may be of wood or somethin of that nature, while the upper edge 37 of the distant part 3 of the loop 20 W1 likewise dig into the support 12 and thus provide a sort ofcramping action which will prevent the device from sliding along the upright support or leg 12. However, in addition there may be a setscrew 40 provided through the side 36 of the loop to assure that the loop will not slide along the member initiallyand until the weight on the arms has been located thereon, or it may be that this securing will provide a holding for the device in case the fit is not exactly correct. In some cases the arms now designated as 21' and 22 as shown in FIG. 6 may be of parallel relation, and a looplike member designated 20' may be ofa size to embrace a ladder instead of a smaller leg such as designated 12 or 14 in the above figures.

In some cases, for more compact packaging for shipment, the device may be made as in FIG. 7 where the loop 45 is cast with integral studs 46 thereon over which tubular arms 47 may be telescoped in assembled form or detached from the studs for more compact packaging.

Ielaim:

1. A scaffolding device comprising a member of looplike shape and of a size to embrace an upright support, a pair of arms secured to said member and extending therefrom in spaced relation with their end portions shaped to engage an upright wall and provide a generally horizontal rest for the formation of a platform, an upright support embraced by said loop member and of a size and shape to be slidable in said member closely fitting the same and at an obtuse angle to said arms, the diagonally opposite edges of said loop being sufficiently angular and sharp to enter said upright support and bind thereon, and a platform located on said arms urging the closely fitting loop member into binding relation with said upright support to prevent sliding therealong.

2. A scaffolding device as in claim I wherein said upright support makes an obtuse angle within the under side of the plane of said arms.

3. A scaffolding device as in claim I wherein the arms have detachable sections.

Claims (3)

1. A scaffolding device comprising a member of looplike shape and of a size to embrace an upright support, a pair of arms secured to said member and extending therefrom in spaced relation with their end portions shaped to engage an upright wall and provide a generally horizontal rest for the formation of a platform, an upright support embraced by said loop member and of a size and shape to be slidable in said member closely fitting the same and at an obtuse angle to said arms, the diagonally opposite edges of said loop being sufficiently angular and sharp to enter said upright support and bind thereon, and a platform located on said arms urging the closely fitting loop member into binding relation with said upright support to prevent sliding therealong.

2. A scaffolding device as in claim 1 wherein said upright support makes an obtuse angle within the under side of the plane of said arms.

3. A scaffolding device as in claim 1 wherein the arms have detachable sections.
