Description

[Detailed description of the invention] This invention relates to a self-propelled height meter for automatically measuring height, and its purpose is to provide a height meter that compactly houses a drive mechanism for raising and lowering a measurement cursor. The cursor is inserted into the housing of the cursor, which is inserted so as to be able to come into contact with the head of the body in order to measure the body height, on a support set upright on the platform. The gist of this device is a height meter that houses a drive roller that is disposed so as to be able to roll against the side surface of a support column, and a motor that rotates the drive roller and causes the cursor to move by itself.

Next, an embodiment of the present invention will be explained with reference to the drawings. In the figure, 1 is the base of the height scale S, 2 is the support installed on the base 1, and 3 is the base on the base 1. In order to measure the height of a standing body, a cursor 4 is inserted into the column 2 so as to be able to come into contact with the head of the body and to be movable up and down.

Reference numeral 5 denotes a housing for the cursor 3, which is assembled so as to be able to be divided into two parts, and has a rectangular insertion hole 6 extending vertically in the vicinity of the center thereof for inserting the support column 2 therethrough. A contact part 7 that is placed opposite to the head of the body and a storage part 8 that houses a drive system for driving the cursor 3 up and down are connected to each other at the front and back of the housing part 8. The pass-through window 8b is opened.

Guides 9 to 9 are rotatably supported on the upper and lower ends of the rear wall 7a of the contact part 7 and the lower end of the front wall 8a of the storage part 8, respectively, in order to guide the raising and lowering of the cursor 3. The rollers are partially protruded into the insertion opening 6 so as to be able to come into contact with the support column 2.

Reference numeral 10 denotes a motor housed in the rear end of the housing section 8, which is driven to rotate in forward and reverse directions by, for example, a power source (not shown), and a pinion 11 is fitted onto the motor shaft 10a.

Reference numeral 12 denotes a gear shaft rotatably mounted horizontally on the upper part of the housing section 8; 13 denotes an upper two-stage gear fitted to the gear shaft 12; It meshes with the pinion 14a of the stage gear 14 and rotates at a reduced speed.

Reference numeral 15 denotes a movable arm that is loosely fitted to the gear shaft 12 so as to be swingable, and extends forward in a downwardly inclined manner. 17 in a counterclockwise direction (in FIG. 2).

A drive roller 18 is rotatably supported at the tip of the movable arm 15 via a support shaft 19, and includes a spur gear portion 18a that is disposed opposite to the lower gear portion 13a of the upper two-stage gear 13 so as to be able to mesh with the lower gear portion 13a, and a support roller. In order to move the cursor 3 up and down by pressing against the support 2, the front end is protruded into the insertion hole 6 through the through-hole 8b.
A roller portion 18b is disposed in parallel with the rear surface 2a and is opposed to the rear surface 2a so as to be able to roll in pressure contact with the drive roller 1.
The cursor 3 can be moved vertically by rotating the cursor 8 in forward and reverse directions.

The drive roller 18 rotates around the spindle 19 and elastically moves in an arc and revolves around the gear shaft 12 disposed above and behind the spindle 19, so when the cursor 3 moves upward, The drive roller 18 that rotates clockwise is pressed in the direction of biting into the column 2 side, increasing the pressure contact between the drive roller 18 and the column 2. On the other hand, when the cursor 3 moves downward, the drive roller 18 that rotates counterclockwise is pressed in the direction of escaping from the support column 2 side, and the pressure contact force between the drive roller 18 and the support column 2 is reduced.
Furthermore, when the cursor 3 comes into contact with the head of the body during its downward movement, the drive roller 18 idles and the cursor 3 stops, and a detection switch (not shown) detects the contact between the cursor 3 and the head of the body. Motor 10 stops.

Note that the amount of movement of the cursor 3 is displayed, for example, digitally by a display circuit (not shown).

Next, the operation and effects of the embodiment having the above configuration will be explained.

In this example, the cursor 3 is inserted into the housing 5 so that it can come into contact with the head of the body in order to measure the height of the column 2 erected on the base plate 1. A drive roller 18 is disposed so as to be able to roll in pressure contact with the rear side surface 2a of the support column 2 for driving, and a motor 1 for rotationally driving the drive roller 18 to make the cursor 3 move by itself.
0 is stored.

Therefore, the drive mechanism for raising and lowering the cursor 3 is simplified and stored compactly in the housing 4, improving the overall appearance of the cursor 3 and the height meter S, and improving the handling and assembly of the cursor 3. can be simplified.

In particular, in this example, the drive roller 18 is supported so that it can move in an elastic arc around the gear shaft 12 disposed above and behind the support shaft 19, which is the center of rotation of the drive roller 18. When the cursor 3 is moving, the pressing force of the drive roller 15 is automatically increased to strengthen the driving force for moving the cursor 3 upward, while when the cursor 3 is moving downward, the drive roller 15 is
As a result, the driving force for moving the cursor 3 downward is automatically reduced, and the driving force for moving the cursor 3 up and down is automatically reduced so that the influence of the weight of the cursor 3 is eliminated. Distribution control can be performed, the vertical sliding state of the cursor 3 can be stabilized and smoothed, and the power consumption for driving the cursor 3 can be reduced.

That is, in the present invention, a cursor is inserted into the housing of the cursor, which is inserted so as to be able to come into contact with the head of the body in order to measure the body height, on a support that is erected on the base, and in order to drive the cursor up and down. A drive roller for moving the cursor up and down is housed, and a drive roller is disposed so as to be able to press against and roll against the side of the support, and a motor for driving the drive roller to rotate and make the cursor move on its own. This is an extremely practical idea as a height gauge because the drive mechanism can be stored compactly and the cursor can be equipped to run on its own.
