Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a belt used when wearing pants, a skirt, or the like on the body.

[Conventional technology]

The belt is composed of a belt-shaped belt body wound around the waist of the body and a buckle for fastening and fixing the belt body. Various belts are made and sold, but from the viewpoint of fastening the belt body,
Holes are formed at a plurality of positions in the longitudinal direction of the belt body, and the hole-shaped belt for fastening the belt body by inserting the engaging pin of the buckle portion into any of the holes, and the holes in the belt body. First, there are two types of belts in which the pressure contact piece of the buckle portion is pressed against the surface of the belt body to fasten the belt body.

[Problems to be solved by the device]

By the way, in any of the above-described conventional belts, the wearer manually tightens the belt body to adjust the degree of tightening of the abdomen by the belt body. However, particularly in the case of a belt with a hole, by appropriately selecting any one of the holes formed in the longitudinal direction of about 3 to 4 and engaging the engagement pin of the buckle portion with the hole, the belt body is formed. Although the degree of tightening to the body by the is adjusted, the holes are usually formed at intervals of about 3 cm, so even if the engagement pin of the buckle portion is engaged with the optimum hole of the belt body, The tightening condition may be too strong or too loose, and it may be difficult to obtain a proper fit.

Also, when the wearer with the belt fastened sits down, the back side of the waist may be pulled and the tightening pressure may be increased, which may cause a burden on the abdomen and the like, which may make the patient suffer. Then, while such a change in tightening pressure is repeated, damage to the peripheral portion of the hole of the belt body is accelerated, and deformation or fatigue of the back side of the waist is caused. Furthermore, when eating, the size around the abdomen becomes large, and people sometimes refasten their belts in front of them in response to it, but they are unsightly to others.

The present invention has been made in view of the above circumstances, and once the belt is worn, the degree of tightening of the abdomen by the belt body is automatically adjusted appropriately without the wearer doing anything. The technical problem is to provide a belt that

[Means for Solving the Problems]

As a means for achieving the above-mentioned object, the present invention attaches a sensor for detecting the degree of tightening by the belt body to the belt body, and an engagement pin for engaging a hole formed in the belt body in the buckle, A screw feed mechanism that reciprocates the engagement pin in the longitudinal direction of the belt body, a reversible rotation motor that rotationally drives a screw of the screw feed mechanism, a power supply unit that supplies power to the reversible rotation motor, and a signal from the sensor. Based on the above, the gist is that the belt is configured by disposing a control mechanism that controls the rotation of the reversible rotation motor.

[Action]

In the belt having the above structure, when the tightening degree by the belt body changes, it is detected by the sensor attached to the belt body, the rotation of the reversible rotation motor is controlled by the control mechanism based on the signal from the sensor, and the reversible The rotary motor is automatically driven to rotate. When the reversible rotation motor rotates, the engagement pin is moved by the screw feeding mechanism, and the belt body engaged with the engagement pin through the hole is automatically moved in the longitudinal direction thereof. Then, when the tightening condition is appropriate, the input signal from the sensor is turned off, the reversible rotation motor is stopped, and the belt body is stopped.

In these figures, 1 is a buckle body board, 2 is a buckle surface board, and these are combined to form a buckle. The belt B has its base end attached to the left end of the buckle cover 2 and extends to the left, and its tip side B'is inserted into the recess 2K of the buckle cover 2 from the right. Has become. Further, the belt body B has a plurality of holes BH formed at equal intervals in the longitudinal direction.

As shown in FIG. 1, the buckle body board 1 is provided with a mechanism for moving the belt body B in its longitudinal direction.
Therefore, a recess space 10 is formed in the buckle body board 1, and an engagement pin 8 for directly moving the belt body B and an integrated drive frame 7 for holding the engagement pin 8 are formed inside the recess space 10.
And are housed so that they can reciprocate freely. That is, 9 is two guide rods that guide the drive frame 7 in a reciprocating manner, and 6 is a screw rod screwed into the drive frame 7 at an intermediate position between the two guide rods 9. The rod 6 is installed rotatably and immovably in the axial direction.

On the other hand, a reversible rotation type miniature motor 3 having an output shaft connected to a screw rod 6 is internally provided on the left side of the buckle body 1. Therefore, when the minimum motor 3 is rotated in the forward / reverse direction, the screw rod 6 is rotated and the drive frame 7 is displaced, so that the belt body B is moved to the left / right via the engagement pin 8 as shown in FIG. Will be done.

Further, the buckle body 1 is provided with a battery 4 which constitutes a power supply unit for supplying electric power to the micro motor 3 to drive it to rotate, and a control circuit 5 for controlling the rotation of the micro motor 3. Although the configuration of the control circuit 5 is not disclosed in detail, the electric power from the battery 4 is supplied to the minimal motor 3 via the control circuit 5. Reference numerals 11 and 12 represent lead wires. The control circuit 5 further includes a lead wire 13 for receiving signals from the switches K1, K2 and K3 and a sensor S1 to be described later.
Lead wires 14 and 15 for receiving a signal from S2 are connected. In the illustrated example, the lead wires 14 and 15 extend from the belt body B attached to the lower left portion of the buckle body panel 1 into the buckle body panel 1 and project to the upper surface of the left end of the buckle body panel 1 to form the control circuit 9. It is connected to the. All lead wires are also buried.

Further, magnets M1 and M2 are embedded at corresponding positions in the buckle body panel 1 and the buckle body panel 2 to facilitate opening and closing of the buckle body panel 1 with respect to the buckle body panel 1.

As shown in the sectional view of the belt body B in FIG.
When the body is tightened, the tightening condition (tightening pressure) can be detected. Reference numeral 16 is a cover for protecting the sensors S1 and S2.

Here, the sensor S1 is for setting the tightening degree on the tightening side, and when the minimum motor 3 rotates in the normal direction to increase the tightening degree to a predetermined pressure, it is detected and a signal is sent to the control circuit 5. To send to. On the other hand, the sensor S2 is for setting the degree of tightening on the loosening side, and when the minimal motor 3 reversely rotates and the belt body B gradually loosens and its pressure becomes equal to or lower than a predetermined pressure, it is detected and a signal is given. Is sent to the control circuit 5. Moreover, the sensor S1 detects the sharp increase in the tightening pressure after tightening the belt body B and setting the predetermined tightening pressure, and sends a signal for reversing the minimum motor 3 to the control circuit 5. Further, the sensor S2 also outputs a signal for causing the minimal motor 3 to rotate in the normal direction when the looseness due to the belt body B falls below a predetermined pressure. These output signals are
It is inputted to the control circuit 5 via the lead wires 14 and 15, respectively. The belt body B is rotated by the forward / reverse rotation of the minimal motor 3.
The hole BH is adjusted within one pitch range.

The lead wires 14 and 15 on the belt body B are embedded in the belt body B. On the other hand, as described above, the buckle front panel 2 is provided with three switches K1, K2, K3. Of these, the switch K1 is for turning on / off the power supply from the battery 4 to the minimum motor 3. Further, the switch K2 is for switching the forward / reverse rotation of the minimal motor 3, and when the pushing operation is continued, the minimal motor 3 is normally rotated at the first time and is reversely rotated at the second time.
The switch K3 is for turning on / off the action of the signals from the sensors S1 and S2 on the control system. The tightening control by the signals from the switches K1, K2, K3 and the sensors S1, S2 is performed by the electric circuit shown in FIG.

Next, the operation of this belt will be described.

First, the engagement pin 8 of the buckle is inserted into the desired hole BH of the belt body B.
To complete the tightening preparation state. Then switch
Press K1 to turn on the power, then press switch K3 to activate the sensor signal. Then, the minimum motor 3 is rotated in the normal direction, and the tightening operation by the belt body B is started. Then, when the predetermined tightening pressure is reached, a signal is output from the sensor S1 and the rotational drive of the minimal motor 3 is stopped.

When the tightening pressure rises sharply, for example when sitting in a seat, with the proper tightening, the sensor S1
Detects this and sends a signal to the control circuit 5. Then, the micromotor 3 is reversely rotated by the operation of the control circuit 5,
The loosening operation is started within the one pitch range of the belt hole BH.
Then, when the predetermined loosening pressure is reached, a signal is output from the sensor S2 and the rotational drive of the minimal motor 3 is stopped. If the loosening operation is performed more than necessary, the sensor S2
Detects this, and the minimum motor 3 is rotated forward. In this way, the tightening condition of the belt body B is automatically adjusted according to the fluctuation of the tightening pressure.

When loosening the belt body B when taking off clothes, the switch K3 is pressed to interrupt the operation of the signal from the sensor, the switch K2 is pressed to reversely rotate the micro motor 3, and the belt hole BH1
Loosen and operate within the pitch. When not using the belt, press switch K1 to turn off the power.

As is clear from the above description, the belt according to the present invention is automatically tightened by simply inserting the belt body into the buckle. Moreover, the tightening pressure is set to a desired value, and the tightening condition is adjusted.

The belt according to the present invention has the above-mentioned configuration, but the scope of the present invention is not limited by the above description and the contents of the drawings, and various modifications can be included without departing from the scope of the invention. For example, the drive frame that holds the engagement pin that engages with the belt hole has a structure in which it is guided by the guide rod. However, this has the function of guiding the reciprocating motion and the function of stopping rotation. The guide rod may have any structure, and therefore, the guide rod does not necessarily have to have a structure of penetrating the drive frame. Further, in the illustrated example, the minimum motor, the battery, and the control circuit are embedded in the buckle main body panel, but the recessed space may be formed to be large and housed in the recessed space like the drive frame. It is practical for batteries and the like to have a structure in which the buckle can be replaced.

Furthermore, the control circuit may have various configurations in relation to the type of sensor and the switch. For example, two sensors, one on the tightening side and one on the loosening side, are installed in the illustrated example, but one sensor is provided and two standard signals for the tightening side and the loosening side are generated in the control circuit 5. A configuration may be provided in which a plurality of standard signal generators and a comparison circuit that compares the standard signal output from these standard signal generators with the detection signal from the sensor are provided. In this way, the configuration of the control circuit differs depending on the type and the number of sensors.

Further, as the switch, the switch K1 may be, for example, a photoelectric switch or a proximity switch, and when the belt body is set on the buckle, the switch is automatically operated so that further automation can be achieved. Other switches can also be omitted in relation to the sensor.

Further, in the illustrated example, the structure in which the buckle cover is easily opened and closed by the magnet is used, but this is not a limitation.

In the above embodiment, the tightening pressure is adjusted within a certain range, but a simple method in which only one sensor is provided and only the tightening pressure is controlled may be used.

[Effect of device]

The present invention is constructed and operates as described above, but when the belt according to the present invention is used, the tightening condition by the belt body can be automatically and properly adjusted. Therefore, the tightening condition is automatically adjusted to the desired value when the tightening pressure rises when sitting or after eating, so that a comfortable feeling is always obtained. Moreover, damage, deformation and fatigue of the belt are reduced.
