The weight measuring device 100 is mounted on the floor and lifts the user's weight by converting the pressure change from the upper plate 110 and the pressure applied from the upper plate 110 to an electric signal. It may include a weight detection unit 120 including).

The upper plate 110 is formed in a flat plate shape, it may be made of various materials such as tempered glass, plastic, stainless steel. In addition, a character, a landscape, a pattern, or the like may be printed on the top plate 110.

One side of the top plate 110 may be equipped with a display unit 30 for displaying the measured weight and height. The display unit 30 is mounted below the upper plate 110, and a transparent window may be formed on the upper plate 110 so that the weight and height displayed on the display unit 30 can be exposed to the outside of the upper plate 110.

The weight sensed by the weight sensing unit 120 is transmitted to the controller 10.

As shown in FIG. 4, the height measuring device 200 has a case 230 mounted on one side of the weight measuring device 100, and the case 230 includes a measurer 210, a winding roll 235, and a spring. A spring 240, a stopper 245, and a deceleration ring 250 may be mounted, and a winding button (not shown) may be mounted through the case 230.

The measurer 210 is formed in the form of a long string which is installed to be pulled out or retracted in the case 230 and is used to measure the height of the user. One end of the measurer 210 exposed to the outside of the case 230 may be equipped with a handle 220 for holding the measurer 210, and a connection piece 215 connecting the handle 220 and the measurer 210. Can be.

When the measurer 210 is withdrawn from the case 230 by the user, the length of the measurer 210 is automatically calculated, and the length of the measurer 210 is the height of the user. Accordingly, the scale does not need to be displayed on the measurer 210, but the scale is displayed on the measurer 210 so that a user may compare the height measured on the display unit 30 with the measured height using the scale of the measurer 210. You may.

As for the winding roll 235, the measuring part 210 is wound up and the tooth | gear is formed in the edge part of the winding roll 235. The winding roll 235 is capable of forward and reverse rotation about the rotation axis, and for convenience of description, the winding roll 235 rotates in the direction in which the measurer 210 is drawn out is called forward rotation, and the measurer 210 Rotation of the take-up roll 235 in the returning direction is referred to as reverse rotation.

The central spring of the take-up roll 235 is mounted, the spring spring 240 is mounted, along the rotational direction of the spring spring 240, the inner end is mounted on the shaft to which the winding roll 235 is fixed, the spring spring 240 ), The outer end is fixed to the inner wall of the take-up roll 235. At this time, the spring spring 240 is mounted so that the measuring device 210 is wound in a direction in which the measuring device 210 is wound on the take-up roll 235 in a state where no force is applied from the outside.

The stopper 245 is installed adjacent to the take-up roll 235, and can be adjusted to be accessible and spaced apart from the take-up roll 235 by a take-up button. One end of the stopper 245 is formed with a locking jaw engaging the teeth of the take-up roll 235, the locking jaw of the stopper 245 is formed to be inclined to one side. Accordingly, when the take-up button is not pressed, the stopper 245 approaches the take-up roll 235 to engage the teeth of the take-up roll 235 and the engaging jaw of the stopper 245, and the stopper 245 is wound up. The roll 235 is not allowed to rotate forward, but the winding roll 235 is prevented from rotating in reverse. That is, although the measurer 210 is allowed to be drawn out, the measurer 210 is prevented from returning.

On the other hand, when the stopper 245 is separated from the take-up roll 235 by the take-up button, the take-up roll 235 is subjected to the rotational force by the spring spring 240, whereby the take-up roll 235 is measured by the measurer 210 The reverse rotation is taken up. When the take-up roll 235 is rotated in reverse, the measurer 210 is wound on the take-up roll 235 to return the measurer 210 which was drawn out of the case 230 into the case 230.

The deceleration ring 250 is formed adjacent to the opening through which the measurer 210 is drawn out and returned in the case 230, and is formed in a cylindrical shape. The measurer 210 wound on the take-up roll 235 is wound around the outer diameter of the deceleration ring 250 and then drawn out to the opening. Accordingly, when the measurer 210 is returned, friction is generated to reduce the return speed when the measurer 210 returns to the inside of the case 230.

On the other hand, in the case 230, a stretch calculation module 270 for measuring how much the measurer 210 is drawn is installed.

The stretch calculation module 270 may be configured in two embodiments, as shown in FIGS. 5 and 6.

According to the first embodiment illustrated in FIG. 5, the extension calculation module 270 includes an optical sensor 275 having a light emitting unit 271 and a light receiving unit 273, and an electrical signal output from the optical sensor 275. It may include a kidney calculation unit 280 to measure the height by using. In order to use the optical sensor 275 of FIG. 5, a reflector capable of reflecting light at regular intervals, such as a scale, must be attached to the measurer 210 or a reflective material is applied.

The optical sensor 275 is installed adjacent to the opening and is disposed to face the meter 210 which is drawn out and returned through the opening. The light emitting unit 271 of the optical sensor 275 continuously emits light, and the light receiving unit 273 receives light reflected by the reflector or the reflective material of the measurer 210.

The extension calculating unit 280 may calculate the total length of the extracted measurer 210 by counting the number of times the light is received and multiplying the interval between the reflective materials by the number of times received.

According to the second embodiment shown in FIG. 6, the stretch calculation module 270 may include a speed sensor 290, a timer 293, and a stretch calculation unit 295.

The speed sensor 290 is installed on the rotation shaft of the take-up roll 235 to sense the rotation speed of the take-up roll 235. The timer 293 is turned on when the take-up roll 235 starts to rotate, and stops when the take-up roll 235 stops rotating. That is, the timer 293 measures the time that the take-up roll 235 rotates, thereby measuring the time taken by the measurer 210.

The stretch calculation unit 295 may calculate the length of the measured measurer 210 using the rotation speed detected by the speed sensor 290 and the time measured by the timer 293.

Thus, the height of the user calculated according to the first and second embodiments of FIGS. 5 and 6 may be transmitted to the controller 10.

Of course, according to the embodiment, in addition to the embodiment of FIG. 5 or 6 described above, it may be implemented to calculate the height of the user by measuring the length drawn by the measurer 210 from the case 230.

The controller 10 matches and stores the weight and height provided from the weight measuring device 100 and the height measuring device 200, and controls to display the stored information to the outside according to a user's command. To this end, the controller 10 may control the operations of the storage unit 20, the display unit 30, the output port 50, and the obesity calculator 40.

In the storage unit 20, the weight and height are matched and stored, and when there are several users, the weight and height of each user are separately stored. To this end, when the controller 10 receives the weight and height measured by the weight measuring apparatus 100 and the height measuring instrument 200, the controller 10 may store data having the same height or a predetermined error range in the data stored in the storage unit 20. The weight and height entered are matched with the corresponding data and stored. At this time, the controller 10 allows the weight and height data to be sorted and stored by date.

In general, the height is rarely changed in adults, and even if the child is growing, the height is rarely increased more than a certain range. Accordingly, a plurality of users may be distinguished by using height as an identifier, and height and weight may be separately stored according to each user.

Of course, it is also possible to enter an identifier for identifying the user before or after measuring the weight and height. In this case, a separate input unit is required. The input unit may be formed of a plurality of buttons, and may include a plurality of character buttons for inputting an identifier in English or Korean, and a confirmation button for selecting an input start or end of the identifier.

On the other hand, the weight and height data stored in the storage unit 20 is provided to the user terminal, it is displayed in the form of a graph in the user terminal may allow the user to easily grasp the change in weight and height. Therefore, the weight and height data is preferably stored in a file in a form that can be displayed on the user terminal. This type of file may include a file having the extension .PPT or .XLS used in an application such as PowerPoint or Excel. Alternatively, the weight and height data may be provided to the user terminal in the form of a text file, and the text file may be converted using an application program capable of generating a graph in the user terminal.

Here, the user terminal may include various terminals such as a PC, a notebook, a tablet PC, a mobile phone, a smart device, and the like. In addition, the storage unit 20 may use an SD memory card, a flash memory, or the like, and when using an SD memory card, the SD memory card may be detached and directly provide data to the user terminal. That is, in this case, the SD memory card slot should be provided, and there is no need to provide a separate output port 50.

The obesity calculator 40 may determine whether the user is obese, normal or underweight by using the weight and height provided by the weight measuring device 100 and the height measuring device 200. The obesity calculation unit 40 may determine whether obesity is determined by using a preset formula for calculating obesity.

The display unit 30 may display the weight of the user calculated by the weight measuring unit 100, the height of the user calculated by the height measuring unit 200, and the degree of obesity from the obesity calculator 40. The display unit 30 may be manufactured using an LCD or the like. On the other hand, according to the embodiment may further include a speaker (not shown) for outputting the user's weight, height, obesity, and the like as a voice.

The output port 50 has a form in which a USB or a connection cable can be coupled to transfer data to the user terminal.

The process of measuring the weight and height in the body measurement device 1 having such a configuration will be described briefly as follows.

When the user climbs on the top plate 110 of the weight scale 100, the pole of the weight scale 100 is inserted into the support leg to press the weight sensor. The weight sensor then detects the weight by the pressure from the pole. The weight sensed by the weight sensing unit 120 is transmitted to the controller 10 and the obesity calculator 40.

As described above, the weight is measured by the weight measuring apparatus 100, and the user pulls out the measurer 210 by pulling the handle 220 exposed to the outside of the case 230 mounted at the bottom of the upper plate 110. At this time, the user pulls out the measurer 210 such that the connecting piece 215 comes to the same position as the upper part of the user's head. Then, the height measuring unit 200 calculates the length from which the measurer 210 is drawn out using the optical sensor 275 or the speed sensor 290, and this length is the height of the user. The height measured by the height meter 200 is transmitted to the controller 10 and the obesity calculator 40.

In the controller 10, the weight and height provided by the weight measuring apparatus 100 and the height measuring instrument 200 are matched and stored in the storage unit 20. In this case, when the weight and height data previously stored exist, the measured height is compared with the stored height to select a height that exists in the same or within a predetermined error range, and the measured data is added to and stored in the corresponding data.

On the other hand, the obesity calculator 40 determines whether or not obesity by using the weight and height provided by the weight measuring device 100 and height measuring device 200. The obesity calculation unit 40 transmits the calculated result to the controller 10.

The controller 10 may display the weight and height measured by the weight measuring unit 100 and the height measuring unit 200 on the display unit 30, and at the same time, may display a result of whether obesity is provided from the obesity calculation unit 40. have.

When the measurement of weight and height and the calculation of obesity are completed, the user releases the handle 220 and presses the winding button. Then, the take-up roll 235 of the elongation measuring instrument 200 rotates in the direction in which the measuring instrument 210 is wound so that the measuring instrument 210 returns to the case 230. At this time, the measuring device 210 is wound around the take-up roll 235 by turning the deceleration ring 250, the speed is reduced.

The weights and heights measured in this way and stored in the storage unit 20 are classified using height as an identifier, and the weight and height data classified according to each height are sorted by date. When the output port 50 is connected to an external user terminal, the controller 10 extracts the weight and height data from the storage unit 20 and transmits the data to the user terminal.

The delivered weight and height data may be displayed in a graph form arranged according to the date at the user terminal. In this case, a separate data processing process may be required at the user terminal according to the file type of the weight and height data.

Since the present body measuring device 1 is manufactured in a simple structure in which the height measuring device 200 is mounted on one side of the weight measuring device 100, the weight and height can be measured simultaneously. In addition, as the user is configured to semi-manual to directly pull out the elongation measuring device 200, by removing the existing complex electronic, mechanical components, not only can significantly reduce the cost, but also small size to move or carry It is easy. Accordingly, it can be easily provided and used in a general home.
