Description

Measurement device with integral angle finder Field of the Invention This invention relates to measurement devices for measuring and marking purposes.

Background of the Invention Measurement devices for measuring and marking purposes include inter alia speed squares, combination squares, right angle squares, and the like. Some measurement devices have a base and an upright planar body when placing the base on a generally horizontal flat surface. The body has two parallel major body surfaces which can be equally placed on a flat surface for measuring and marking purposes. The body surfaces can have the same or different measurement markings. Some measurement devices include a bubble vial for indicating an inclination of the generally horizontal flat surface.

Summary of the Invention The present invention is directed towards measurement devices for measuring and marking purposes and including an integral angle finder for enabling two modes of use: placing either major body surface on a flat surface or setting a base on an inclined surface for indicating its inclination. The measurement devices are intended to provide additional angle finding capability in a convenient and compact manner without detracting from conventional use. The measurement devices can be formed from suitable metal and/or plastic materials.

Detailed Description of the Drawings Figure 1 and Figure 2 show a conventional speed square 10 including a base 11 and a generally triangular planar body 12. The base 11 has a base setting surface 13 for placing on a generally horizontal flat surface, a base top surface opposite the base setting surface 13, a base front surface 16, a base rear surface opposite the base front surface 16, a base left end surface 18 and a base right end surface 19 opposite the base left end surface 18. The base top surface 14 has a central longitudinal centerline 21. The base 11 has the following dimensions: length L, thickness T1, and height H1. The base 11 includes a bubble vial 22 for indicating an inclination of a generally horizontal flat surface on placing the base setting surface 13 thereon.

The body 12 includes a first edge 23, a second edge 24 and a hypotenuse edge 26. The body 12 has a thickness T2 where T1>T2. The first edge 23 is mounted on the central longitudinal centerline 21 such that the body 12 stands upright on the base 11 placed on a generally horizontal flat surface. The body has a first major body surface 27 and a second major body surface 28. The body 12 includes one or more throughgoing apertures 29 between the first major body surface 27 and the second major body surface 28 and measurement markings 31 adjacent the throughgoing apertures 29 and along the second edge 24 and the hypotenuse edge 26.

Figure 3 to Figure 5 show a measurement device 50 configured as a speed square including a base 51 and a generally triangular planar body 52. The base has a base setting surface 53 for placing on a generally horizontal flat surface, a base top surface 54 opposite the base setting surface 53, a base front surface 56, a base rear surface 57 opposite the base front surface 56, a base left end surface and a base right end surface 59 opposite the base left end surface 58. The base has the same length L1 and thickness T1 as the base 11 but has a lower height H affording a more compact design. The base top surface 54 has a central longitudinal centerline 61.

The body 52 includes a first edge 62, a second edge 63 and a hypotenuse edge 64 and has the same thickness T2 as the body 12. The first edge 62 is mounted on the central longitudinal centerline 61 such that the body 52 stands upright on the base 51 placed on a generally horizontal flat surface. The body has a first major body surface 66 and a second major body surface 67. The body 52 includes one or more throughgoing apertures 68 and measurement markings adjacent the throughgoing apertures 68 and along the second edge 63 and the hypotenuse edge 64.

The speed square 50 includes an integral angle finder 71 slidingly mounted therein in a transverse direction with respect to the central longitudinal centerline 61. The angle finder 71 includes an angle finder housing 72 fixedly mounted in the measurement device 50 and a bubble vial 73 rotatably mounted therein. The angle finder housing 72 includes a first angle finder housing component 74 and a second angle finder housing component 76 for snap fitting on the first angle finder housing component 74 for entrapping the bubble vial 73 therebetween. The angle finder housing 72 has a first major angle finder housing surface 77 parallel with the first major body surface 66 and a second major angle finder housing surface parallel with the second major body surface 67. The first major angle finder housing surface 77 and the second major angle finder housing surface 78 have angular markings 79 for indicating an angle of the bubble vial 73 with respect to the base setting surface 53. The angle finder housing 72 has a thickness T3 in a side elevation view of the measurement device 50 facing either the second edge or the hypotenuse edge 64 where T1>T3>T2.

The speed square 50 includes a generally arch shaped angle finder aperture 81 between the first major body surface 66 and the second major body surface and an angle finder channel 82 between the base front surface 56 and the base rear surface 57. The angle finder aperture 81 is continuous with the angle finder channel 82 such that the angle finder 71 is slidingly mounted in both the base 51 and the body 52.

Figure 6 to Figure 8 show use of the speed square 50 as follows: Figure and Figure 7 show that the angle finder 71 enables equal use of the first major body surface 66 and the second major body surface 67 for measuring and marking purposes.

Figure 6 shows for using the first major body surface 66 for measuring and marking purposes on a flat surface, a user urges the downward protruding length of the base 51 to abut against the flat surface ’s edge and depresses the second major body surface 67 on the flat surface causing the second major angle finder housing surface 78 to be flush with the second major body surface 67 and the first major angle finder housing surface 77 to protrude from the first major body surface 66. The angle finder 71 ’s thickness T3 is preferably dimensioned such that the first major angle finder surface 77 is flush with the base front surface 56.

Figure 7 shows for using the second major body surface 67 for measuring and marking purposes on a flat surface, a user urges the downward protruding length of the base 51 to abut against the flat surface ’s edge and depresses the first major body surface 66 on the flat surface causing the first major angle finder housing surface 77 to be flush with the first major body surface 66 and the second major angle finder housing surface 78 to protrude from the second major body surface 67. The angle finder 71 ’s thickness T3 is dimensioned such that second major angle finder surface 78 is flush with the base rear surface 57. Figure 8 shows use of the speed square 50 for measuring an inclination of an inclined surface.

Figure 9 and Figure 10 show a measurement device 50 configured as a combination square including an integral angle finder 71. The combination square 50 can be placed on either its major body surfaces on a flat surface for measuring and marking purposes or its base setting surface on an inclined surface for indicating its inclination. Figure 11 and Figure 12 show a measurement device 50 configured as a right-angle square including an integral angle finder 71. The right-angle square can be placed on either its major body surfaces on a flat surface for measuring and marking purposes or its base setting surface on an inclined surface for indicating its inclination.

While particular embodiments of the present invention are illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the scope of the invention.
