Patented Jan. 13, 1942 UNITED STATES'PATENT OFFICE POSTURE GAUGE Clifford M. Martin, Denver, 0010. Application March 10, 1941, Serial No. 382,560
This invention relates to improvements in posture gauges and has reference more particularly to an improved gauge of the type shown, described and claimed in my copending application, Serial No. 314,915, filed January 22, 1940.-
It is well known that posture has an important bearing upon health and that only few people, comparatively speaking, habitually assume a body posture which even approaches the ideal and which permits the nervous system and the vital organs of the body to function properly.
It is the object of this invention to provid a posture gauging apparatus which can be used in schools, in the home and by the medical profession to demonstrate correct posture and assist in obtaining the same.
The above and any other objects that may hereinafter appear and which may be determined from a reading of my above identified patent are attained by means of a construction and an arrangement of parts that will now be described in detail and for this purpose reference will be had to the accompanying drawings in which the inventicn has been shown in its preferred form, and in which:

In the drawings reference numeral l0 desi nates a vertical supporting member which may be formed from a piece of plyboard or similar material. Secured to the front surface of this member is a mirror II that is held in place by means of an angle metal strip 12. The mirror is narrower than the supporting board I0 and the latter is provided along each of its vertical edges with a guide [3 which in the embodiment shown, consists of a strip of sheet metal having a flange [4 that extends along the rear of the support l0 and which is connected by means of a wall i5 with the front 16, the latter being provided with a slot I1. The wall I8, terminates in a flange l9 that is secured to the support by screws or other suitable means. The guides on opposite sides of the support are identical with the exception that they are rights and lefts. The front surface of flange I9 is preferably provided with an inch scale as indicated at 20. The inclined edges of the support are provided with metal angles 2| that serve to protect the edges and also to give the device a finished appearance. Adjustably secured to each guide is a slide 22 that has been shown as of greater length than width and which projects over the surface of the mirror as shown in Figures 1 and 4. One end of the slide 22 is provided with an opening for the reception of a bolt 23 whose head 24 is positioned between the front surface of the support and the rear surface of the wall IS with a wing nut 25 by means of which the slide can be clamped in adjusted position to the guide. A pivot rod 26 is positioned in front of the slide 22 and spaced from the front surface thereof. The ends of the pivot rod are attached to the slide, as indicated by reference numeral 21. The pivot rod extends parallel with the slide and substantially perpendicular to the slot ll of the guide. In the embodiment illustrated, the slide is formed from sheet metal and has an inner body 28 of wood, as shown in Figure 7. When the slide is made narrow, as shown in the drawing, it is provided with a downwardly extending portion 29 having a wall that projects inwardly along the inner wall of the guide and this downwardly projecting portion serves as a stop for an elbow supporting shelf that will presently be described. The lower ou'ter corner which has been designated by reference numeral 30 engages theinner wall l8 of the guide and serves to limit downwardly rotation. It is apparent that the bolt 22 cannot, by itself, prohibit rotation of the slide, but serves principally to position the slide vertically along the guide. By having a downward projection as above described, whose wall engages wall I8, it is evident that downward rotation is positively prevented without subjecting the clamping bolt 22 to any excessive strains. It will be seen from Figure 4, that the vertical wall of projection 29 is inclined slightly with respect to the lower wall of the slide so that when the latter is turned upwardly about the bolt 22, the slide can move freely and when the lower end of the projection contacts wall l8 of the guide, the slide will be held in a position at right angles to the slot l1. Where the mirror is held in place by an angle [2, the projection 29 can be provided with a wall 3| whose upper end contacts the angle 12 as indicated at 32. The latter is not necessary because the wall which engages wall l8 serves this function with sufficient effectiveness. It is now evident that the slides 22 may be adjusted vertically along the guides and that they may be adjusted independently of each other for a purpose which will hereinafter appear. Suspended from the pivot bar 26 is an elbow supporting shelf 33. This shelf is slidable along the pivot bar 26 and is provided with a rear wall 34 that engages the front surface of the downward projection 29 and the latter therefore prevents the shelf from turning about the pivot bar. The shelf 33 is provided with an upwardly extending portion 35 whose upper end has a pair of spring clips 36 whose purpose will hereinafter appear. Pivotally attached to the pivot bar is a shoulder positioning arm 31 which is formed from two telescopically related tubular members 38 and 30. Member 39 is the smaller and projects into member 38 and is provided at its outer end with a plate 40 which engages the shoulder of a person in the manner indicated in Figure 3.
Referring now more particularly to Figure 5, it will be seen that the tubular member 39 is provided with a plurality of openings M. Tubular member 38 has one opening for the reception of an inwardly bent portion of a spring 42 that serves to latch the parts in position in the manner indicated in Figure 8.
Referring now to Figure 7, it will be seen that the inner end of part 38 is provided with a hinge member 43 that encircles the pivot bar 26. When the arm 3'! is in horizontal position, its end engages the free surface of the rubber cushion that forms the back wall of the elbow supporting shelf. Due to the fact that the shoulder positioning member 3'! is hinged above the upper surface thereof, as shown in Figure 7, its downward movement is limited by its engagement with the rubber pad 44 as above indicated. Arm 31, however, can be folded upwardly into the position shown in dotted lines in Figure '7 andwhen in this position it is held against accidental downward movement by the spring clip 36 as shown in Figure 5.
In the application above identified, somewhat similar shoulder positioning arms have been shown, but they are not extensible and no elbow support or shelf has been provided. Experience has shown that in order to obtain the best results th person whose posture is being tested should have his arms forwardly extending and his elbows resting on the shelves 33 in the manner shown in Figures 1, 2 and 3. The person to be tested for posture is positioned in front of the device which, for this purpose, is supported at suitable height, either from a wall or from some other suitable support. The person with arms at sides, stands in front of the device and the operator adjusts the position of arms 31 for height and width of shoulders. The person now rests his elbows on the shelves and adjusts the position of his feet accordingly, after which he drops his arms to his sides. The operator now adjusts the length of the arms 3'! and positions them as shown in Figure 2. Many people have one shoulder somewhat higher than the other and this makes it necessary to independently adjust the shoulder engaging arms and the elbow supporting shelves.
Since the technic connected with the operation of devices of this type has been quite fully explained in the patent above identified, and since this invention relates to a mechanical improvement, the details of obtaining the desired posture and the advantages and disadvantages of correct and incorrect posture will not be elaborated on in this description.
Particular attention is called to the fact that the shoulder positioning means are independently adjustable in a vertical position and also in a horizontal position. It is obvious that different persons are of different widths between the shoulders which makes the horizontal adjustment imperative. The addition of the elbow supporting shelves is of great importance as by this means better results are obtained and the value and effectiveness of the apparatus is greatly increased.
In Figures 1, 2 and 3, a person's body has been shown by broken lines in the position it occupies during the posture gauging operation.
Attention is called to the fact that when the persons elbows are supported on the elbow shelves, the shoulder spacing bars 31 must be in vertical position as shown by dotted lines in Fi ures 2 and 5, because it is impractical to have the shoulder spacing bar in operative position while the elbows rest on the shelves.
