Abstract

A stadiometer for measuring height of a person to the nearest millimeter and sixteenth-of-an-inch has an upright rail movably supporting a slide carrying a height measuring arm. A scale on the rail is covered with a transparent shield connected to the slide. A line on the shield aligned with the arm is used to read the scale to provide height data of a person.

Claims

1. A stadiometer for measuring the height of a primate comprising:

an upright rail having upright side walls that converge relative to each other and a back wall forming an upright groove, and side sections extended laterally from each of said side walls, scale means having English and metric graduations on one of said side sections, slide means engageable with and movable along said side walls, said slide means having walls located in friction sliding engagement with said side walls of the rail whereby the slide means maintains its adjusted position on the rail and is manually movable to a selected position on the rail, biasing means located in said groove and engageable with said rail to bias the walls of the slide means in friction sliding engagement with said side walls of the rail, means securing the biasing means to said slide means, a generally horizontal arm secured to said slide means and extended outwardly from said rail, shield means extended over the scale means, means securing the shield means to the slide means, said shield means being movable with the slide means along said rail and relative to the scale means, said shield means having at least a transparent portion located over the scale means whereby the scale means is visible, and means on said shield means aligned with the arm to provide visual information of the location of the arm relative to the scale means thereby providing measurement data of the height of a primate when the arm engages the top of the head of a primate.

2. The stadiometer of claim 1 wherein:

the side sections of the rail project rearwardly and laterally away from the side walls, said shield means having portions extended over said side sections of the rail and the scale means.

3. The stadiometer of claim 1 wherein:

the English and metric graduations are located in vertical side-by-side relation with equivalent graduations laterally aligned with each other.

4. The stadiometer of claim 1 including:

holder means supporting the arm, and means connecting the slide means to the arm and retaining a portion of the arm on the holder means.

5. The stadiometer of claim 4 wherein:

the holder has a transverse groove, said arm having an end located in said transverse groove and retained by said means connecting the slide means to the arm.

6. The stadiometer of claim 4 wherein:

the shield means has a portion located between the holder means and slide means, said means connecting the slide means to the arm clamping the shield means between the holder means and slide means.

7. The stadiometer of claim 1 including:

low friction means located between said side walls of the rail and the diverging walls of the slide means to facilitate movement of the slide means relative to the rail.

8. The stadiometer of claim 7 wherein:

the low friction means is a plastic tape secured to said walls of the slide means and engageable with said side walls of the rail.

9. The stadiometer of claim 1 wherein:

the biasing means comprises a leaf spring having opposite ends engageable with the rail.

10. The stadiometer of claim 1 wherein:

the side walls of the rail converge outwardly toward each other, said slide means having walls located adjacent said side walls of the rail.

11. The stadiometer of claim 10 wherein:

the biasing means comprises a leaf spring connected to the slide means, said leaf spring having ends located in sliding engagement with the back wall of the rail to retain the walls of the slide means in friction sliding engagement with said slide walls of the rail.

12. The stadiometer of claim 10 wherein:

the slide means has a base projected outwardly from the rail, said shield means having a portion mounted on the base whereby the shield means is retained in spaced relation relative to the rail and scale means.

13. The stadiometer of claim 10 including:

low friction means located between said side walls of the rail and the walls of the slide means to facilitate movement of the slide means relative to the rail.

14. The stadiometer of claim 13 wherein:

the low friction means is a plastic tape secured to said diverging walls of the slide means and engageable with said side walls of the rail.

15. The stadiometer of claim 10 wherein:

the rail has opposite upright edge means having upright grooves, said shield means having upright edges projected into said grooves.

16. The stadiometer of claim 15 wherein:

the edge means includes inwardly directed lips forming said grooves, said upright edges of the shield means extending into said grooves under said lips.

17. An apparatus for measuring the height of an object comprising:

an upright rail having at least one upright side section, said rail including upright side walls that converge outwardly toward each other providing the sides of an upright groove in said rail, scale means on said side section having graduations providing information as to the height of the object, slide means movably mounted on said rail for movement along said rail, said slide means having walls located in friction sliding engagement with said side walls of the rail whereby the slide means maintains its adjusted position on the rail and is manually movable to a selected position on the rail, biasing means located in said groove and engageable with said rail to bias the walls of the slide means in friction sliding engagement with said side walls of the rail, means securing the biasing means to said slide means, a generally horizontal arm, means securing said arm to said slide means and extended outwardly away from said rail, shield means secured to the slide means extended over the scale means, means securing the shield means to the slide means, said shield means being movable with the slide means along said rail and relative to the scale means, said shield means having at least a transparent portion located over the scale means whereby the scale means is visible, and means on said transparent portion of the shield means aligned with the arm to provide visual information of the location of the arm relative to the scale means, thereby providing data as to the height of the object when the arm engages the top of the object.

18. The apparatus of claim 17 wherein:

the side section of the rail projects rearwardly and laterally relative to the arm.

19. The apparatus of claim 17 wherein:

the scale means includes English and metric graduations located in vertical side-by-side relation with equivalent graduations laterally aligned with each other.

20. The apparatus of claim 17 wherein:

the means securing said arm to said slide means includes holder means supporting the arm, and means connecting the slide means to the arm and retaining a portion of the arm on the holder means.

21. The apparatus of claim 20 wherein:

the holder means includes a transverse groove, and said arm having an end retained in said transverse groove by said means connecting the slide means to the arm.

22. The apparatus of claim 20 wherein:

the shield means has a portion located between the holder means and slide means, said means connecting the slide means to the arm clamping the shield means between the holder means and slide means.

23. The apparatus of claim 17 wherein:

the biasing means comprises a leaf spring connected to the slide means, said leaf spring having ends located in sliding engagement with the rail.

24. The apparatus of claim 17 wherein:

the slide means has a base projected outwardly from the rail, said shield means having a portion mounted on the base whereby the shield means is retained in spaced relation relative to the rail and scale means.

25. The apparatus of claim 17 wherein:

low friction means located between said side walls of the rail and the walls of the slide means to facilitate movement of the slide means relative to the rail.

26. The apparatus of claim 17 wherein:

the rail has upright edge means having an upright groove on said upright side section, said shield means having an upright edge projected into said groove.

27. The apparatus of claim 26 wherein:

the edge means includes an inwardly directed lip forming said groove, said upright edge of the shield means extending into said groove under said lip.
