Description

[Detailed description of the invention] "Industrial application field" This invention is an automatic height and weight scale that instantly measures and digitally displays the height and weight of a person when the person enters a predetermined position on the measurement step. This invention relates to a folding type automatic height and weight scale in which the pole is folded in half at approximately the middle to protect the cursor part that operates precisely.

Conventionally, simple height and weight scales for home use have been known to have a height measurement column that can be folded or telescopically expanded and contracted, but this type of automatic height and weight scale uses an electric motor to precisely operate the cursor. There is no such structure that can be folded freely, and it has disadvantages in that it is bulky and inconvenient to handle during transportation and packaging, and is uneconomical due to high packaging and transportation costs.

However, the present proposal is based on this type of automatic height and weight scale.
The height measuring pole is divided into two parts, an upper pole and a lower pole, which are connected by a hinge, and the lower pole is equipped with a precision-operating cursor that can move up and down in the cursor sliding groove of the upper pole when folded. It is stored in a storage pocket so that it can be locked, and the folded state is maintained stably to protect the cursor and the cursor sliding groove. It is an object of the present invention to provide a folding type automatic height and weight scale which can be locked by a locking pin inserted into the pin hole and which protects the precision part, which eliminates the above-mentioned drawbacks and maintains the extended state stably.

Now, detailed description will be given of the attached drawings showing an example of the implementation of the present invention.

Figures 1 and 2 show the height and weight scale of the present invention when it is extended, as seen from the front and side, respectively. FIGS. 3, 4, and 5 show the same folded state, as seen from the front, side, and top direction, respectively. Figure 6 is the same as Figure 2.
- Figure 7 shows Figure 3 cut along line A.
It is cut along line B, and Figure 8 shows the folded version using casters to make it portable.

Reference numeral 1 denotes a cursor, which stops at the top dead center in a cursor sliding groove 12 (described later) drilled in an upper pole 2a (described later) at the time of non-measurement such as at the end of measurement, and is used by the person to be measured as a step stool 4a of a digital weighing scale. When you enter a predetermined position on the measurement step 4, it starts descending electrically, stops when it touches the top of the person's head, returns to top dead center again, and instantly measures the height when it stops at the top of the head. This constitutes a digital height meter that digitally displays the height, and together with the cursor sliding groove 12 constitutes a precision part. 2 is a square tube-shaped pole of the digital height meter, which includes an upper pole 2a and a lower pole 2.
The lower pole 2b is divided into two parts approximately in the middle, and the lower end of the lower pole 2b is fixed to the measuring platform 4 in an upright manner.
As shown in FIG. 4, the upper pole 2a is folded in half on the front surface of the lower pole 2b. Reference numerals 3 and 3 refer to casters consisting of small wheels fixed downward on both rear sides of the measuring platform 4, which do not touch the floor surface under normal conditions, but when folded and transported as shown in FIG. Part pole 2a,
When the measurement step 4 is tilted backwards together with 2b, it comes into contact with the floor surface, making it easier to carry. 6 is a cursor protection storage pocket, and the height meter pole 2
The cursor 1 that has stopped at the top dead center of the cursor 1 is protected and housed, and is formed into a horizontal trapezoid shape with the lower base disposed on the front surface at the lower front of the lower pole 2b. 7
An upper fixing claw is attached to the upper end of the cursor sliding groove 12 (to be described later) of the upper pole 2a so as to protrude from the front surface, and has an upward hook 7a formed at its tip. Reference numeral 8 denotes a lower locking claw, and as shown in FIG. 7, a hook 8a that engages with the hook 7a is molded at the tip, a shaft 8b is fixed to the base, and the shaft 8b is fixed to the base.
is pivotally supported on the side surface of the lower pole 2b at the bottom of the cursor protection storage pocket 6, and the hook 8a is always projected from the through hole 6a on the lower surface of the storage pocket 6 by a spring (not shown) attached to the shaft 8b. As shown in FIG. 7, the hook 7a of the fixing claw 7 is engaged with the folding tab to maintain the folded state stably. Reference numerals 9 and 9 indicate angle-shaped brackets, which are connected to the upper pole 2a and the lower pole 2b, respectively.
It is fixed on both sides of the divided portion C so as to face each other, and has arcuate ribs 9a on the front and rear respectively.
are attached, and the flange portions 9b of the brackets 9, 9,
A lock pin hole 10 is drilled in 9b, and the pin hole 10
A lock pin 11 is provided to be inserted into each lock pin hole 10, and the pin 11 is inserted into each lock pin hole 10 to stably maintain the extended state as shown in FIG. Reference numeral 12 denotes a cursor sliding groove, which is bored only on the front surface of the upper pole 2a, and means (not shown) for raising and lowering the cursor 1 by a motor is provided only on the upper pole 2a, so that the height measuring pole 2 can be moved up and down. Paul 2a,
This is to prevent the precision operating part from being affected when folding in half at 2b. Reference numeral 13 denotes a lever, which is fixed to one end of a shaft 8b on which the lower locking claw 8 is pivotally supported, and the lever 13 is fixed to one end of a shaft 8b that supports the lower locking claw 8.
The hook 8 protrudes from the through hole 6a so that the hook 7a of the lower claw 8 always engages with the hook 8a of the lower claw 8.
b is pushed back against the elasticity of the spring, and the hook 7a is
This is to release the engagement. The present invention has the above-mentioned structure, and when in use, operate the lever 13 to release the lock of the fixing claw 7 from the lower locking claw 8, hold the upper pole 2a, extend it from the lower pole 2b by the hinge 5, and divide it. By inserting the lock pins 11 into the respective lock pin holes 10 of the flange parts 9b, 9b of the brackets 9, 9 on both sides of the part C, the extended state can be stably maintained, and when folding, the lock pins 11 are pulled out from the respective lock pin holes 10. , upper pole 2
When a is bent onto the front surface of the lower pole 2b by the hinge 5, the cursor 1 is stopped at the top dead center during non-measurement such as at the end of measurement, so the cursor 1 is placed in the cursor protection storage pocket 6 at the bottom of the lower pole 2b. The storage is protected, and the hook 7a of the upper fixing claw 7 engages with the hook 8a of the lower locking claw 8 to stably maintain the folded state, so the precision part does not come into contact with other objects and be damaged. Even when using a weight scale, the height scale pole 2 can be divided into upper and lower poles 2a and 2b and folded into a compact state, and the cursor 1, cursor sliding groove 12, etc. can be safely protected, making it easy to package and transport. There is no risk of damage to precision parts during time, etc., and packaging and transportation costs are reduced.

In addition, the automatic height and weight scale does not take up much space when being put away and stored, making it convenient when it is used for mobile diagnosis and the like.
