Description:
BACKGROUND 
     It is well known in the art to provide measuring devices useful for measuring the height of persons wherein two measuring rods are telescopically arranged and a single column of measuring units is disposed on each side of said rods. In application Ser. No. 743,089 filed Nov. 18, 1976, now U.S. Pat. No. 4,134,213 a height measuring device is described in which the height of persons can be measured in two different types of height measuring units such as English height measuring units, for example, inches, on the one hand, and metric height measuring units, for example, centimeters, on the other. This height measuring device depends upon the use of a step to compensate approximately for the difference between the English units and the metric units. Thus, in a height measuring device of the type described wherein inches appear in one of the vertical columns on the faces of the telescopic units and centimeters appear on the other vertical column in side-to-side relationship with the first column, the English units start at fifty-one inches as the uppermost line on the fixed telescopic column and 130 centimeters on the other vertical fixed column so that a step of 0.18 inch or 0.46 centimeter in vertical height is required between the two measuring levels in order to be able to read the height of a person, either in English units (inches) or the roughly equivalent metric units (centimeters). The rough equivalency between the English units and the metric units is taken care of by the step. 
     In the past in telescopic units for measuring height, it has always been customary for the lower fixed rod to have a height of fifty-one inches and for the upper telescoping rod to have a height beginning at fifty-one inches and increasing, for example, to seventy-eight inches. Except for the step-type height measuring device previously described, insofar as is known, no one has heretofore devised a height measuring device in which the height of persons can be measured in two different types of height measuring units such as English height measuring units, on the one hand, and metric height measuring units, on the other. 
     OBJECTS 
     One of the objects of the present invention is to provide a height measuring device useful for measuring the height of persons wherein the height can be read in English measuring units such as inches or in metric height measuring units such as centimeters, which is generally similar to the aforementioned telescopic height measuring device except that the step is eliminated. 
     Other objects and advantages will appear from the following description in conjunction with the accompanying drawing.

     BRIEF SUMMARY OF THE INVENTION 
     In accordance with the invention a simplified height measuring device useful for measuring the height of persons is provided having telescopically arranged height measuring rods with faces containing parallel vertical columns of different types of height measuring units such as English height measuring units on the one hand, and metric height measuring units, on the other, characterized by the fact that the height of the fixed rod is exactly equivalent in height measuring units such as English units to a whole number of height measuring units such as metric units thereby eliminating a step at the upper end of the fixed rod. More specifically, the height of the fixed rod is 50 inches which exactly corresponds to 127 centimeters. 
     DETAILED DESCRIPTION OF THE INVENTION 
     The embodiment of the invention illustrated in the drawing comprises a fixed rod 1 having a face 2 sufficiently wide to accommodate two columns of numerals 3 and 4 arranged parallel to one another or in a side-to-side relationship. The column of numerals 3 consists of English height measuring units in inches vertically disposed on face 2 spaced apart in numerical sequence. The column of figures 4 consists of metric height measuring units in centimeters vertically disposed on the face 2 spaced apart in numerical sequence. A vertical movable rod 5 is telescopically mounted on the fixed rod 1 so as to be vertically slidable with respect to said fixed rod 1. The movable rod 5 has a face 6 which is sufficiently large to accommodate two columns of numerals 7 and 8 in side-to-side relationship, i.e., substantially parallel to one another. The column of measuring units 7 consists of English measuring units such as inches and the column of height measurements 8 consists of metric height measuring units such as centimeters. 
     A headpiece generally shown at 9 comprises an elongated member 10 extending at right angles outwardly from the face 6 of movable rod 5 and also at right angles to the face 2 of fixed rod 1. 
     Headpiece 9 is L-shaped as shown in FIG. 3 and comprises a vertical portion 11 and a horizontal portion 12. The horizontal portion 12 extends beyond the vertical portion 11 as shown in FIG. 2. 
     The headpiece 9 pivots around the rivet 13 which is swaged at the outer end. A washer 14 is provided between the swaged end of the rivet and the mounting means for the headpiece which is generally shown at 15. The headpiece 9 pivots upwardly in the direction of the arrow from the horizontal to a vertical position and downwardly from a vertical position of a horizontal position. It also has a downwardly extending stop member 16, the inner end of which rests against the outer face of the movable rod 5 when the headpiece is in the horizontal position. 
     The mounting means 15 for the headpiece 9 comprises a U-shaped bracket 17, one leg of which 18 is affixed to movable rod 5 in any suitable manner, for example, by inserting it through an opening in movable rod 5 and swaging it. The opposite leg 19 of the U-shaped bracket 17 extends along the side of the fixed rod and is spaced therefrom by a space 20 which is sufficient to permit it to pass over the side of fixed rod 1 when the movable rod 5 is moved downwardly in telescopic association with the fixed rod 1. When the top of movable rod 5 passes below the top 21 of fixed rod 1 the underside of the horizontal portion 12 of the headpiece 9 becomes an indexing member and from its position the height measurement either in inches or centimeters can be measured on the fixed rod 1 after the outer portion 10 of headpiece 9 is contacted with the head of a person whose height is to be measured. 
     For the purpose of the present invention the maximum height measured on the fixed rod is 50 inches which exactly corresponds to 127 centimeters. Thus, the top edge 21 of fixed rod 1 is the measuring level for both inches and centimeters and there is no necessity to provide a step in order to round off the equivalent of 50 inches in centimeters. When a person whose height is to be measured is taller than 50 inches, the measurements are obtained by moving the movable rod 5 upwardly so that the mounting means 15 and the headpiece 9 are beyond the top 21 of fixed rod 1. 
     The numerals on the base of movable rod 5 are arranged so as to increase numerically from 50 inches at the top to any predetermined larger number at the bottom such as 78 inches and as the movable rod 5 is raised with the portion 10 of headpiece 9 contacting the head of the person whose height is to be measured, the edge 21 of fixed rod 1 will be the index for determining the height measurement both in inches and also in centimeters. 
     The height measuring scale previously described can be secured in any suitable manner with the fixed rod 1 and the telescopic rod 5 vertically disposed either to a wall or to the column of a beam scale as illustrated in FIG. 1. This can be accomplished by means of L-shaped brackets 22 and 23 each having a side 24 and 25, respectively, secured to a side of a fixed rod 1 and the connecting sides 26 and 27 fastened in any suitable manner either to a wall or to a column 28 of a beam scale as illustrated in FIG. 1. 
     The beam scale illustrated in FIG. 1 is conventional and does not constitute a part of the invention except to the extent that it is adapted to be used in combination with a height measuring scale of the type herein described, the height measuring scale being generally indicated at 29. When the height measuring scale is used in combination with a beam scale as shown in FIG. 1 the height measurements are obtained in the usual manner by having a person stand on the platform 30 of the weighing scale and by adjusting the movable rod portion of the height measuring scale until the headpiece generally indicated at 9 is in contact with the top of the head of the person whose height is to be measured. The height measurements are then determined in the manner previously explained. For shorter persons whose height does not exceed fifty inches, the telescopic rod 5 is lowered until the mounting means 15 is over the outside of the fixed rod 1 whereby the underside of the horizontal portion 12 of the headpiece 9 adjacent the face of the fixed rod serves to index the height measurements on the columns of numerals on the face of the fixed rod 1. 
     For taller persons having a height greater than fifty inches or the corresponding number of centimeters, the movable rod 5 is moved vertically until the underside of headpiece 9 contacts the top of the head of the person whose height is to be measured. At this point the top 21 of fixed rod 1 serves as an index to indicate the height measurements either in inches or in centimeters. 
     It is thought that the invention and its numerous attendant advantages will be fully understood from the foregoing description, and it is obvious that numerous changes may be made in the form, construction and arrangement of the several parts without departing from the spirit or scope of the invention, or sacrificing any of its attendant advantages, the forms herein disclosed being preferred embodiments for the purpose of illustrating the invention.
