Description

Technical Field

[0001] The following description relates to height and weight measuring devices, and more specifically, to a height measuring device and a weight measuring device, wherein the height measuring device utilizes a stand with a track on the back and a top plate with an inclined center of gravity, and the weight measuring device utilizes a support member including multiple bridges for vertically transmitting force to the neck of a weighing sensor. Background Art

[0002] Height and weight measurement are required for various purposes in hospitals, schools, homes, workplaces, etc. Height measurement is generally to determine the height of the user by measuring the height of the user when the user is standing upright, and weight measurement is to determine the weight of the user by measuring the force with which the user presses down on the base on which he is standing.

[0003] However, the track that moves the top plate for measuring height up and down is arranged in front of the vertical pole of the height measuring instrument, which leads to a limited field of view, and the display unit is arranged on the side of the vertical pole, which restricts the space for installing the height measuring instrument. In addition, when it is arranged on a sloping ground, the downward force based on the user's weight cannot be accurately transmitted, resulting in errors in the measurement results. Summary of the invention

[0004] Technical issues to be solved

[0005] The present invention utilizes a stand with a track on the back and a top plate. The top plate has a center of gravity that tilts forward. During the process of measuring height, the top plate touches the user's head and is lifted up to apply pressure to the touch switch, and then resets itself using its own weight. As a result, while maintaining high measurement accuracy, an aesthetic effect can be expected.

[0006] The multiple bridges of the support member connected to the weighing sensor of the present invention bend independently of each other. Therefore, when the bottom of the axis of the support member standing on the ground is inconsistent with the pressure direction of the user pressing down on the neck of the weighing sensor, the user's weight can be measured highly accurately.

[0007] In the present invention, when a predetermined condition is met, the measurement result is displayed by changing from the first direction to the second direction, so that the user who is the measurement object or the supervisor who manages and supervises the measurement process can easily confirm the measurement result.

[0008] In the present invention, the top plate can wait at the first height or the second height according to the setting state, thereby making the top plate wait at an appropriate height according to whether the measured object is an adult or a child, and the measurement can be performed more efficiently.

[0009] Technical solutions to the problem

[0010] According to the embodiment, the height measuring instrument includes: a base plate; a stand, which is connected to the base plate for support and has a track on the back; a moving part, which moves the track up and down; a tact switch, which is arranged on at least a part of the moving part; and a top plate, which surrounds the stand and moves up and down with the moving part, and is hinged to the moving part, and applies pressure to the tact switch while touching the user's head and lifting it upward when measuring the height.

[0011] In the height measuring instrument according to the embodiment, the top plate is a panel whose center of gravity is inclined to the front rather than the back, and when not in the state of being lifted up, it returns to its original position based on its own weight to prevent the touch switch from being pressed.

[0012] In the stature measuring device according to the embodiment, the top plate has a curved form so that the center of gravity is inclined.

[0013] In the stature measuring device according to the embodiment, the front portion of the stand is formed of a flat plate, and the back portion of the stand includes a groove in which the rail is disposed.

[0014] In the stature measuring device according to the embodiment, when not measuring, the top plate waits at a first height in a first setting state, and waits at a second height lower than the first height in a second setting state.

[0016] In the height measuring instrument according to the embodiment, the predetermined condition is at least one of a first threshold time after the touch switch is pressed to reset, a second threshold time after the measurement is completed, a third threshold time after the weight change of the measurer is sensed from the bottom plate, and other operation commands are received.

[0017] According to the embodiment, the height measuring instrument also includes: a weighing sensor, which is pasted under the base plate and measures the weight of the user by bending the neck; and a support member, which supports the base plate from the ground and transmits the force of the user standing on the base plate to the weighing sensor.

[0018] In the height measuring instrument according to the embodiment, during the measurement process, when the axial direction of the support member standing on the ground is inconsistent with the pressure direction of the user pressing down on the neck, the multiple legs of the support member will also bend independently of each other, thereby, compared with the axial direction, the support member presses the weighing sensor in the direction of bending the neck of the weighing sensor.

[0019] According to one embodiment, the weight measuring device includes: a base plate for a user to stand on; a weighing sensor attached to the bottom of the base plate to measure the weight of the user by bending the neck; and a support member that supports the base plate from the ground and transmits the force applied by the user standing on the base plate to the weighing sensor.

[0020] In a device according to one embodiment, during the measurement process, when the axial direction of the support member standing on the ground is inconsistent with the pressure direction of the user pressing down on the neck, the multiple bridges of the support member will also bend independently of each other, thereby, compared with the axial direction, the support member presses the weighing sensor in the direction of bending the neck of the weighing sensor.

[0021] In the device according to an embodiment, the plurality of bridges of the support are respectively spiral-shaped, and connect a first portion of the support connected to the weighing sensor and a second portion of the support connected to the ground.

[0023] Effects of the Invention

[0024] According to one embodiment, a stand having a track on the back and a top plate are utilized. The top plate is based on a center of gravity tilted forward. During the process of measuring height, the top plate touches the user's head and is lifted up to apply pressure to the touch switch, and then resets itself again using its own weight. As a result, an aesthetic effect can be expected while maintaining high measurement accuracy.

[0025] According to one embodiment, multiple bridges of the support member connected to the weighing sensor are bent independently of each other. Therefore, when the bottom of the axis of the support member standing on the ground is inconsistent with the pressure direction of the user pressing down on the neck of the weighing sensor, the user's weight can be measured with high accuracy.

[0026] According to an embodiment, when a predetermined condition is satisfied, the measurement result is displayed by changing from the first direction to the second direction, so that the user who is the measurement object or the supervisor who manages and supervises the measurement process can easily confirm the measurement result.

Commonly used terms as defined in dictionaries should be understood as having the meanings in the relevant technical content and should not be interpreted as idealized or overly formalized meanings if not clearly defined in this specification.

[0042] Below, the example embodiments will be described in detail with reference to the accompanying drawings. The specific structures and functions of the embodiments mentioned in this specification are for illustrative purposes only, and the scope of the embodiments should not be interpreted as the limited content recorded in this specification. A person of ordinary skill in the art can make various changes to the embodiments described below. In addition, the same reference numerals in the drawings represent the same parts, and the description of the known functions and structures is omitted.

[0043] Figure 1 2 is a diagram showing a height measuring device according to an embodiment.

[0044] Reference Figure 1 According to an embodiment, a height measuring instrument 100 includes a bottom plate 110, a stand 120, a moving part, a touch switch, and a top plate 130. The height measuring instrument 100 can measure the height of a user standing on the bottom plate 110. In addition, the height measuring instrument 100 can also measure the weight of a user standing on the bottom plate 110.

[0045] The bottom plate 110 may be a portion on which a user as a measurement object steps. As will be described in detail later, the user's weight may be measured by a load cell and a supporter disposed below the bottom plate 110 .

[0046] The stand 120 is connected to the bottom plate 110 for support, and has a track at the back. The front of the stand 120 is a flat plate, and the back of the stand 120 includes a groove, and the track is arranged on the groove. Therefore, the track is arranged at the back of the stand 120 instead of the front, which can improve the aesthetic effect.

[0047] Figure 1 Although not shown in the figure, the moving part can move the track located at the back of the stand 120 up and down. Figure 1 Although not shown, a tact switch is disposed on at least a portion of the moving portion.

[0048] The top plate 130 surrounds the stand and moves up and down with the moving part, and is hinged to the moving part, and is lifted up after touching the user's head during the height measurement process, while applying pressure to the touch switch. As will be described in detail later, the top plate 130 may be a curved panel, with its center of gravity more inclined to the front than the back.

[0049] According to one embodiment, before the user whose height is to be measured stands on the foot pedal 110, the top plate 130 may wait at a position higher than the user's height, and move downward along with the moving part when the user stands on the foot pedal 110. After touching the user's head, the top plate 130 may return to its original position, and measure the user's height based on the height of the user's head when it touches the user. At this time, while touching the user's head, the top plate 130 may apply pressure to the touch switch. This will be described below.

[0050] When the measured object is a child whose height is shorter than that of an adult, in order to touch the child's head, the distance that the top plate 130 moves downward from the waiting position becomes longer, and the corresponding descent time is prolonged. Therefore, it is necessary to set different waiting positions of the top plate 130 according to the measured object. For example, when not being measured, the top plate 130 waits at a first height in a first setting state; and in a second setting state, the top plate 130 waits at a second height lower than the first height. Among them, the first setting state is a state in which the measured object is set to an adult, and the second setting state is a state in which the measured object is set to a child. For example, the first height can be 2m, and the second height can be 1.8m. In addition, different first heights and second heights can be set without restriction.

[0051] Figures 2 to 5 2 is a diagram illustrating a top plate according to an embodiment.

[0052] Figure 2 1 is a perspective view of the top plate 130 according to an embodiment. The top plate 130 is a panel whose center of gravity is more inclined to the front than the back. During the height measurement process, when the user's head is not touched and raised, it can be restored based on its own weight to prevent the touch switch from being pressed. Figure 2 In the embodiment of the present invention, the upper end on the left side is equivalent to the front part, and the lower end on the right side is equivalent to the back part. For example, the top plate 130 can be designed as a curved surface, thereby having an inclined center of gravity.

[0053] The top plate 130 may have a hole at the back, and the stand is located in the hole so that the top plate 130 moves up and down along the stand. Figure 2 Only the rail 210 disposed on the back of the stand is shown, and the moving part 220 can move the rail 210 up and down.

[0054] The head stopper bracket 230 can limit the movement of the top plate 130. For example, when the top plate 130 touches the user's head and is lifted up, the top stopper bracket 230 can limit the rotation angle within a specified range. In addition, when the top plate 130 returns to its original position due to its own weight without touching the user's head, the top stopper bracket 230 limits the rotation angle within a specified range so that the top plate 130 remains horizontal to the ground.

[0055] Figure 3 is a side view of the top plate 130 according to one embodiment.

[0056] As described above, the top plate 130 has a structure in which the back portion surrounds the vertical pole and the front portion touches the user's head when measuring the height. When measuring the height, when the front portion of the top plate 130 touches the user's head to lift it upward, the back portion of the top plate 130 applies pressure to the touch switch 310. The height measuring instrument measures the user's height based on the height of the top plate 130 that senses the pressing of the touch switch 310. After measuring the height, the top plate 130 returns to its original position due to its own weight, thereby preventing the touch switch 310 from being pressed.

[0057] Figure 4 A portion 410 of the top plate 130 that contacts the moving part according to an embodiment is shown. In order to prevent the top plate 130 from tilting due to the tilting of the center of gravity of the top plate 130 according to an embodiment, an additional portion 410 is added to the top plate 130. For example, the portion 410 has a structure in which the upper side is wider than the lower side, so that the top plate 130 is kept horizontal.

[0058] Figure 5 A top stop bracket 230 is shown for limiting movement of the top plate 130 according to one embodiment.

[0059] Figure 6 2 is a diagram illustrating a base plate according to an embodiment.

[0060] Reference Figure 6 According to an embodiment, the bottom plate 110 may include a display unit 610 for displaying a measurement result. For example, the measurement result may include at least one of the height and weight of the user. The display unit 610 is included in the bottom plate 110, which can minimize the space constraint of the location of the height measuring instrument.

[0061] According to one embodiment, the display unit 610 can control the display direction of the measurement result. For example, the display unit 610 can first display the measurement result in a first direction, and then if a predetermined condition is met, display the measurement result in a second direction different from the first direction. For example, the first direction is a direction in which a user standing on the base plate 110 with his back to the pole can more easily read the measurement result, and the second direction is the opposite direction of the first direction, which is a display direction in which a supervisor who faces the user to manage / supervise the measurement process can easily read the measurement result, or a direction in which a user who has completed the measurement can easily read the measurement result after getting off the base plate 110. However, the embodiments of the first direction and the second direction are not limited thereto, and a variety of embodiments can be adopted without restriction.

[0062] According to an embodiment, the predetermined condition may be at least one of a condition that a first threshold time has passed after the touch switch is reset, a condition that a second threshold time has passed after the measurement is completed, a condition that a third threshold time has passed after the weight change of the measurer coming down from the bottom plate is sensed, and a condition that other operation commands are received. The threshold time includes 0 seconds or a time longer than 0 seconds, and the time is not limited.

[0063] As an example, when the condition is that the first threshold time has passed after the touch switch is reset, the measurement results are displayed in the first direction before the reference point and in the second direction after the reference point, when the first threshold time has passed since the top plate that touches the user's head moves upward along with the moving part and returns to its original position due to its own weight to prevent the touch switch from being touched.

[0064] As another example, when the condition is that the second threshold time has passed after the measurement is completed, the measurement may include at least one of height measurement and weight measurement. When measuring height, the height measuring instrument can determine the user's height based on the position of the pressed touch switch. At this time, based on the second threshold time from the time of determining the height, the user's height as the measurement result is displayed in the first direction before the reference point, and displayed in the second direction after the reference point. Alternatively, in the case of measuring weight, based on the second threshold time from the time when the user's weight standing on the bottom plate is measured, the user's weight as the measurement result is displayed in the first direction before the reference point, and displayed in the second direction after the reference point. Alternatively, when applicable to all height measurements and weight measurements, based on the second threshold time from the time when the user's height and weight are measured, the height and weight as the measurement results are displayed in the first direction before the reference point, and displayed in the second direction after the reference point.

[0065] As another example, when the condition is that a third threshold time has passed after a weight change of the measured person stepping down from the bottom plate is sensed, a weight change will occur after the user who has completed the measurement stepping down from the bottom plate. The measurement result is displayed in a first direction before the reference point based on the third threshold time from the time point when the weight change is sensed, and is displayed in a second direction after the reference point.

[0066] As another example, when the condition is that other operation commands are received, an operation command for the display direction of the measurement result may be received from a user who is the measurement object or a supervisor who manages / supervises the measurement process. The measurement result may be displayed in a direction determined by the input operation command.

[0067] Figures 7 to 11 2 is a diagram illustrating a load cell and a support member according to an embodiment.

[0068] Reference Figure 7 , shows a weighing sensor 700 disposed at the lower portion of the base plate 110 according to one embodiment.

[0069] According to one embodiment, the weighing sensors 700 may be disposed at four vertices of the bottom plate 110 (see Figure 6 620), each weighing sensor 700 may include a force transmission part 710 and a neck 720. The weighing sensor 700 is a sensor that can measure physical quantities such as force or load. When the weighing sensor is subjected to force, an electrical signal corresponding to the corresponding force is generated, and the weight is determined based on the generated electrical signal. For example, when the force transmission part 710 is subjected to a force based on the user's weight, the force transmission part 710 transmits the received force to the neck 720, and the neck 720 bends to a certain extent based on the transmitted force. The bending amount of the neck 720 is measured using a strain gauge to determine the user's weight.

[0070] Figure 8 FIG. 7 is a side view of a load cell 700 according to an embodiment. A force 810 based on the weight of a user may be applied to the force transfer portion 710 .

[0071] Referring to Figures 9a and 9b, the conditions required for accurately measuring the user's weight by bending the necks 910 and 920 of a weighing sensor according to an embodiment are shown. Figure 9a shows a figure in which the base plate is configured on a flat ground, and the force applied to the neck 910 based on the user's load is perpendicular to the neck 910, and Figure 9b shows a figure in which the base plate is configured on an inclined surface, and the force applied to the neck 920 based on the user's load is not perpendicular to the neck 920. As can be confirmed in Figure 9b, when the force applied based on the user's load is not perpendicular to the neck 920, the neck 920 will not bend sufficiently, and the user's weight may not be accurately measured. Therefore, it is very important that the force applied based on the user's load is perpendicular to the neck, and the support member is used to achieve verticality, which will be referred to in detail. Fig.10 as well as Fig.11 Detailed description.

[0072] Reference Fig.10 According to an embodiment, the support member 1000 may include a first portion 1010 connected to the load cell, a second portion 1020 connected to the ground, and a bridge 1030 in a spiral form connecting the first portion 1010 and the second portion 1020. The bridge 1030 may be plural. The bridge 1030 may include a first fixing portion 1031 fixed to the first portion 1010, a second fixing portion 1032 fixed to the second portion 1020, and a connecting portion 1033 connecting the first fixing portion 1031 and the second fixing portion 1032 in a structure parallel to the periphery of the second portion 1020. In other words, the bridge 1030 protrudes from the first portion 1031 connected to the ground in the direction of the second portion 1020 connected to the load cell, and then moves parallel to the periphery of the second portion 1020 and is connected to the second portion 1020.

[0073] Such a support member 1000 structure ensures freedom in all directions, thereby transmitting force vertically to the neck of the weighing sensor.

[0074] Reference Fig.11 , shows a side view of a support member 1000 connected to a weighing sensor according to an embodiment. The support member 1000 may further include a height adjustment portion 1110. The height adjustment portion 1110 is threaded and can be rotated by a user to adjust the height so that the bottom plate can be kept level.
