Abstract

A tool that enables to frame walls, floors and roofs by providing two clamps, adjustable in distance to each other.
This stud alignment clamp is holding two studs in a desirable distance, so that those studs can be nailed to a plate.
This invention allows to keep your hands away from the area, where framing members need to be nailed, which reduces the risk of injuries.
Furthermore this stud alignment clamp allows to set framing members in the right spot without taking measurements and making right-angled marks.
Because of its two clamps, framing members can be sat in the right spot, even if the framing members are different in dimensions.
Similar devices could not solve this problem so far.

Description

2,680,504 -1-Title of the Invention Stud Alignment Clamp Technical Field This device relates to the construction business. The invention enables construction workers such as carpenters to frame walls, set trusses, rafters or floor joists in place.

Background of the Invention The purpose of this invention is to set framing members in the right spot.
This tool enables to do this in a very short time and in a more convenient and safe way.
There are a few devices on the market so far, for setting studs in place but they have several problems, which can be solved by the present invention.
To set framing members (in the following named as studs) into a desirable distance to each other, whether making pencil marks or using a stud spacer, the studs always need to be sat with the same side to the marks or stopping parts (Figure 1).
The tool showing in Figure 1 is not helpful, because the studs have to be pressed against the stopping parts, while nailing them to a plate at the same time.
In Figure 2 a tool is showing, in which the studs are not set to the right spot, because of a discrepancy in dimensions of the studs. A usual discrepancy of 1/16 of an inch can easily add up to 1 inch or more on a wall of 15 to 20 studs, which is not acceptable.
Another problem to frame walls is that the studs need to be held until studs and plates are nailed together. This is a huge risk to be injured, especially by using air-pressure operated nail guns.
The present invention eliminates those problems because of its two clamps.
Summary of the Invention The present invention places studs, joists, trusses or rafters in desirable spots, no matter if they are different in dimensions or twisted.
The stud alignment clamp consists of two clamps is adjustable for desirable stud-distances.
Both clamps force studs into the right spot and into right angles. This device can be fixed to one stud by using one clamp, while another stud can be located in a predetermined distance from the first stud by using the second clamp.
The stud alignment clamp is usable for all pole-shaded parts, which need to be sat in the same distance linear pattern.
Whereas this stud alignment clamp needs only one hand to be operated with, the other hand can nail the stud to the plate at the same time. There is no need for holding the stud with one hand during nailing, which is one of the benefits of this invention: The reduction of risk to be injured during the nailing process.
Furthermore, framing can be done in a time saving manner, because this tool can be used with one hand only.

2,680,504 -3-Detailed Description In the following description the tool will be used to frame a wall consisting of a bottom plate, a top plate and studs in between.
The studs need to be nailed to the plates in right angles and in the same distance linear pattern.
To make this work, measurements have to be taken and square marks have to be made for each stud on both plates. By using the invented tool, this will be not necessary anymore.
Once the first stud is nailed to the bottom plate, the stud alignment clamp has to be sat on this stud (Figure 4). The tool has to be fixed on the first stud by pulling lever 1 (Figure 5) in order to push the rod 2 (Figure 5) towards the stud. Rod 2 runs through steel plate 3 (Figure 5), which moves the rod 2 towards the stud. The spring 4 (Figure 5) keeps the steel plate3 in place. Another steel plate 5 (Figure 5) stops rod 2 from sliding back, so that the entire tool is fixed to the stud and can not be removed, until steel plate 5 (Figure 5) is pushed towards the tool body.
Now, while the tool is holding itself, lever 6 (Figure 5) can be lifted and the second stud can be placed between the lever 6 and the stop part 7 (Figure 3). By pushing down the lever 6 (Figure 6), the second stud 7 (Figure 6) will be forced into the right spot and in case the stud is twisted, the stud will be aligned right-angled to the plate.
Now, the plate can be nailed to the second stud.
By pushing steel plate 5 (Figure 6) towards the tool body, the rod 2 will be released and the tool can be sat on the next stud.
The procedure starts again by fixing the tool to the second stud with clamp 11 (Figure 3).
The described work process takes about three seconds.
From my experience over the last six years, using this tool saves about 30% to 50 % of the time, depending on what has to be built.
The distance "A" between the stop part 7 (Figure 3) and stop part 8 (Figure 3) is adjustable from 11 inches to 25 inches, which covers all distances, necessary for framing walls, floors and roof constructions.
The clamp 10 (Figure 3) is attached to the outer steel tube 9 (Figure 3) and is slidable on the inner steel tube 12 (Figure 3).
The wing screw 13 (Figure 3) locks the outer steel tube to the inner steel tube at the desirable settings.

Claims

Claims The embodiments of the invention in which an exlusive property or privilege is claimed are defined as follows:

1. A manually operable stud alignment clamp for setting pole-shaded construction parts in the same distance linear pattern comprising:
- A bar with a stop part and a bar clamp to fix a first pole part against the stop part.
- A pivotable jaw clamp slidable on the bar with locking means capable to lock the pivotable jaw clamp on the bar in predetermined location.
- A lever attached to the pivotable jaw for forcibly locating the following pole part element against a fixed jaw of the pivotable jaw clamp to locate the following pole part in predetermined distance from the first pole.
