Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a three-dimensional clothing size measuring device by transmitting and receiving ultrasonic signals. ◇ Configuration of conventional example and its problems ・ Conventionally, the size of clothing such as suits and suits has been measured. The size is determined by the size at the time of cutting the clothing material, and the three-dimensional size of the clothing is almost never determined. On the other hand, what is important about clothes sewn in this way is how well they fit the human body when clothed, and therefore the value determined by the two-dimensional size,
There is a need for a relationship with the three-dimensional size of clothes when worn.

Purpose of the Invention The present invention has been made to solve the above-mentioned conventional problems, and involves transmitting and receiving ultrasonic waves from the mannequin side with clothes on the mannequin.

An object of the present invention is to provide a three-dimensional clothing size measuring device that can easily measure the three-dimensional size of the inside of clothing.Structure of the InventionIn order to achieve this object, the present invention provides a stand for mounting a mannequin that is movable up and down. A horizontally movable ultrasonic sensor is provided on the arm, and an opening through which ultrasonic waves can pass is provided in a part of the mannequin. Ultrasonic waves are transmitted, the ultrasonic waves reflected on the inside of the clothing are received again, and the round-trip propagation time of the ultrasound waves is calculated from this received signal to determine the distance between the ultrasonic sensor and the clothing. The object is to sequentially eat all kinds of food and use the same operations to determine the three-dimensional size of clothing without contact.

Description of examples Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a three-dimensional clothing size measuring device according to an embodiment of the present invention. A stand 1 for a mannequin device has a manikin device coupling part 3 on the upper part of a column 2, and an ultrasonic sensor 4 is attached to an arm 6 connected to the column 2 via a rotary coupling part 5 that can move up and down. There is. Arm 6
allows rotation while detecting the rotation angle around the support.

A mannequin 7 mounted on a stand 1 is divided into several parts, and an opening 8 is provided between each part.

The ultrasonic sensor 4, the scanner 9 attached to the rotary coupling 6, is electrically connected to an electric control unit 10, the ultrasonic sensor 4 is connected to said electric control unit. ,. Gawa 4.1.
'e□, 2 is from engineering. The output of the receiver 12 is subjected to signal processing in a signal processing section 13, subjected to the same action as a normal ultrasonic distance measuring device, and output as distance information. Also,
The rotational coupling section 6 and each circuit section within the electric control unit 10 are controlled by signals from a control section 14.

,゛ If a piezoelectric vibrator having a center frequency of about 1 MH2 and a concave shape with a diameter of about 20 M is used as the ultrasonic sensor 7'46, the ultrasonic wavelength in the air is about 0.34.
wL, and the ultrasonic beam diameter can be narrowed down to about 5M. The ultrasonic waves emitted from the ultrasonic sensor 4 pass through the opening 8 of the mannequin 7, are almost all reflected by the first reflector, the inner side 5 of the clothes, for example, the inner fabric of the clothes, and are reflected again by the ultrasonic sensor 4. and is then converted into distance information by an electrical circuit.

When using the three-dimensional clothing size measuring device as described above, the distance between the main part of the clothing attached to the mannequin 7 and the ultrasonic sensor 4 can be determined by rotating inside the mannequin while the position is controlled by the electric control unit 10. It is obtained by transmitting and receiving ultrasonic signals with the ultrasonic sensor 4 that scans in the vertical direction, and then sequentially determining the distance between the ultrasonic sensor 4 and the clothing.

As described above, according to this embodiment, the ultrasonic sensor 4 is attached to the tip of the arm 6 that rotates around the support post 2, and can be moved in the vertical direction of the support post 2, so that the ultrasonic sensor 4 can be attached to the divided mannequin 7. Since ultrasonic waves can be transmitted and received through the plurality of openings 8 and the spatial position of the ultrasonic sensor 4 can be detected, the three-dimensional size of clothing worn on a mannequin can be detected without contact. .

Note that the shape of the mannequin is not limited to the split type shown in FIG. 1; as shown in FIG. Sound waves are transmitted through the opening 8 to clothing (not shown) worn on this mannequin, and the reflected waves are transmitted through the opening 8 again.
The 3D size of the clothing can be detected by receiving distance information as before.

In these cases, it is also desirable that the mannequin and stand have a structure that allows them to be removed.

Furthermore, instead of a single ultrasonic sensor, it is also possible to arrange a plurality of ultrasonic sensors on the same horizontal plane or the same vertical plane and drive them simultaneously or by switching, thereby measuring the three-dimensional size of clothing at high speed.

Effects of the Invention In summary, the present invention provides an ultrasonic sensor that is movably attached to a stand on which a mannequin is mounted and has an opening in a part thereof, and transmits the ultrasonic sensor to clothes mounted on the mannequin through the opening of the mannequin. This product provides a three-dimensional garment size measuring device that calculates the distance between the ultrasonic sensor and the garment by transmitting ultrasonic waves and receiving the ultrasonic waves reflected from the inside of the garment, and can quickly measure the three-dimensional garment size. It can be measured without contact without causing any deformation, and it is possible to easily evaluate the fit to the human body in a clothed state.
