Right hand level holder

A right angle level holder includes a right angle level base, and a plurality of thumb screws. The right angle level base has two legs which are disposed 90 degrees apart from one another. Each leg has a slot which receives a straight level. A first side of the slot has an inverted acute angle surface which is structured to retain a first edge of a straight level. The second side of the slot has a raised portion which is high enough for tapping a threaded hole. The thumb screw is threaded in the threaded hole to retain a second edge of a straight level. The thumb screw has a first end which is adapted for turning by finger pressure. The second end of the thumb screw has a swivel tip that is adapted for retaining the second edge of a straight level.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates generally to right angle levels and more 
specifically to a right angle level holder which retains two straight 
levels at a right angle to each other. 
2. Discussion of the Prior Art 
There are several level designs which address the need for a right hand 
level in the construction industry. An example of some of these right hand 
levels are U.S. Pat. No. 2,466,829 by Sprinkel, U.S. Pat. No. 3,303,569 by 
Wyatt, and U.S. Pat. No. 4,531,301 by Tau. The length of these levels are 
long enough to give an accurate reading for erecting walls and the like. 
However, the field of art lacks a device which is adapted to receive two 
straight levels and constrain them at a right angle to each other. 
Accordingly, there is a clearly felt need in the art for a right hand level 
holder which is adapted to hold two straight levels at a 90 degree angle 
to each and thus allow a user to utilize existing straight levels which 
they already own. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a right hand 
level holder which is adapted to hold two straight levels at a 90 degree 
angle to each and thus allow an user to utilize existing straight levels 
which they already own. 
According to the present invention, a right hand level holder includes a 
right angle level base, and a plurality of thumb screws. The right angle 
level base has two legs which are angularly disposed 90 degrees apart from 
one another. Each leg has a slot which receives a straight level. A first 
side of the slot has an inverted angle surface which is structured to 
retain a first edge of a straight level. The second side of the slot has a 
raised portion which has a height sufficient for tapping a threaded hole. 
The thumb screw is threaded into the hole to retain a second edge of a 
straight level. The thumb screw has a first end which is adapted for 
turning by finger pressure. The second end of the thumb screw has a swivel 
tip that is adapted for retaining the second edge of a straight level. 
Accordingly, it is an object of the present invention to provide a right 
angle level holder which is adapted to retain two straight levels at a 
right angle to each other. 
It is a further object of the present invention to provide provide a right 
angle level holder which allows a user to combine existing straight levels 
for use as a right angle level. 
Finally, it is another object of the present invention to provide a right 
angle level holder which spares a user the cost of purchasing a separate 
right angle level. 
These and additional objects, advantages, features and benefits of the 
present invention will become apparent from the following specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
With reference now to the drawings, and particularly to FIG. 1, there is 
shown two perspective views of a right angle level holder 1 disposed on a 
cement block wall. With reference to FIG. 2, the right angle level holder 
1 includes a right angle level base 10, and a plurality of thumb screws 
12. The right angle level base 10 has a first leg 14 and a second leg 16 
which are at a right angle to one another. The length of the right angle 
level base 10 is preferably two, four, six, or eight feet to support the 
full length of a standard sized straight level. The length of right angle 
base 10 may also be shorter than the full length of the straight level. 
The first leg 14 has a first slot 18 disposed on an outside surface of the 
right angle level base 10 and the second leg 16 has a second slot 20 
disposed on an outside surface of the right angle level base 10 
perpendicular to the first slot 18. Each slot is adapted to receive a 
bottom of a straight level. Each slot has a first side which is shaped as 
an acute angle 22 such that it retains a first edge of the bottom of the 
straight level. The value of the acute angle 22 is preferably 45 degrees. 
A second side of each slot has a raised portion 24 which has a height that 
is sufficient to form threads, or a cavity to facilitate attachment of a 
thumb screw or fastener means. 
The thumb screw 12 shown is a preferable method for retaining the first and 
second straight levels in the right angle level base 10, other types of 
fastener devices may also be used. With reference to FIG. 5, the thumb 
screw 12 includes a substantially threaded body 28 and a swivel tip 32. A 
thumb lever 26 is disposed at a first end of the substantially threaded 
body 28 and a swivel knob 30 is disposed at a second end of the threaded 
body 28. The thumb lever 26 is designed for allowing the thumb screw 12 to 
be rotated against a straight level by finger pressure. The swivel tip 32 
has a slanted end 34 which is structured to retain the second edge of the 
straight level. The angle of the slanted end 34 is preferably 45 degrees. 
The swivel tip 32 is attached to the swivel knob 32 by any prior art 
swaging method. When the thumb screw 12 is rotated, the swivel tip 32 is 
prevented from rotation with a finger such that it fits over the second 
edge of the straight level. It is preferable that a thumb screw 12 be 
disposed at one foot intervals along the length of the right angle level 
base 10. 
FIG. 4 shows how the second straight level 102 may be inserted into a 
second slot 20 of the second leg 16. The second straight level 102 may 
also be inserted into the second slot 20 by pushing thereof into an end of 
the second slot 20. FIG. 3 shows a front view of a right angle level 
holder 1 with a first straight level 100 and the second straight level 102 
retained thereby. The right angle level holder 1 may be used for measuring 
the level of outside corners, as well as inside corners. 
While particular embodiments of the invention have been shown and 
described, it will be obvious to those skilled in the art that changes and 
modifications may be made without departing from the invention in its 
broader aspects, and therefore, the aim in the appended claims is to cover 
all such changes and modifications as fall within the true spirit and 
scope of the invention.
