A height-measuring device in which there is provided a vertically-mounted ruler element and associated slide-mount in which slides a slide having a lower surface for resting on the head of a person to be measured. The slide has a pair of rearwardly extending flanges that act as runners for sliding in channels formed in the slide-mount. The slide has a bracket extending from the flanges, which bracket has a pair of side surfaces which mounts a hexagonal-head screw, the head of which is nonrotatably mounted in one side surface. A locking nut is mounted at the end of the screw and is rotatable in a first direction to urge the pair of side surfaces, which are made of hard plastic, toward each other, and, therefore, also the flanges, to cause the flanges into clamping relationship with the inner surface walls of the pair of channels. The lower surface of the slide is coplanar with a surface which indicates on the ruler element directly adjacent thereto the correct height measurement. |
