<Configuration>

As shown in FIGS. 2 and 3 , the double arm scale for learning according to a preferred embodiment of the present invention includes the double arm scale 100 and the character 200 .

First, the double-armed scale 100 includes a pedestal 110, a body 120, a horizontal member 130, a measuring member 140, a pair of plates 150, a weight 160, and a number weight 170. can be provided.

Here, the pedestal 110 may be manufactured to have a certain size so that the main body 120 and the character 200 of the scale 100 are lifted and fixed. This pedestal 110 can be made into various pretty shapes in the form of flower petals for young learners. This pedestal 110 has a certain area on a plane, and a level may be attached to check the degree of horizontality of the floor on which it is placed. In addition, the pedestal 110 may be installed with one or more legs that are fixed by being inserted or pulled out so that the height can be adjusted for leveling. Therefore, even if the ground is uneven, the pedestal 110 is leveled, and the horizontal member 130 is ultimately leveled, so that the weight placed on the plates 150 on both sides can be accurately measured.

In addition, as shown in FIGS. 3 and 4, the main body 120 is fixed on the pedestal 110, passes through the center of the horizontal member 130, and the measuring member 140 may be mounted so as to pivot. To this end, the main body 120 may include a front body 121 and a rear body 122 that are fastened to each other. As these front body 121 and rear body 122 are coupled to each other, the middle portion of the horizontal member 130 can be fastened. In addition, the measuring member 140 of the main body 120 may be mounted on the upper part of the front body 121 on the character 200 side.

In addition, as shown in FIGS. 4 and 5, the horizontal member 130 has the main body 120 so that the plates 150 are fixed on both sides and can seesaw horizontally or to one side by the weight of the plates 150 on both sides. can be mounted on To this end, the horizontal member 130 may include an upper leveler 131, a lower leveler 132, and a plate fixing member 133.

The upper leveler 131 may have a certain length and be mounted on both front ends of the plate fixing member 133 so as to rotate axially. The upper leveler 131 may have a convex portion 131a processed in a substantially inverted "U" shape on the center portion.

The lower leveler 132 has a certain length and may be mounted on both front ends of the lower part of the plate fixing member 133 so as to pivot. For example, the lower leveler 132 may be manufactured to have the same length as the upper leveler 131, and may include a center of gravity protrusion 132a protruding toward the convex portion 131a at the center point, which is the center of gravity. The horizontal axis of rotation 132b at the front end of the center of gravity protrusion 132a is the center of gravity of the entire horizontal member 130 and may be mounted on the main body 120 to pivot. In addition, the leveler rotational shaft 132b is also mounted to the measuring member 140 so as to pivot, so that it can become a rotational axis of the measuring member 140 . In addition, the measuring member rotating shaft 132c at the base of the center of gravity protrusion 132a may be mounted to pivot with the measuring member 140 . As a result, when the lower leveler 132 is tilted to one side around the leveler rotation shaft 132b, the measuring member rotation shaft 132c rotates in the opposite direction, and the measurement member 140 also rotates the leveler rotation shaft 132b. It can be axially rotated to one side around .

The plate fixing member 133 is a member on which the plate 150 is lifted, and the front ends of both sides of the upper leveler 131 and the lower leveler 132 can be mounted so that the top and bottom fixing member rotation shafts 133a rotate. there is. Accordingly, the plate fixing member 133 can always be maintained in a horizontal state due to the axial rotation of the fixing member rotating shaft 133a even when the upper leveler 131 and the lower leveler 132 are inclined to one side.

In addition, the measurement member 140 is a member that visually shows the difference in weight by rotating clockwise or counterclockwise according to the difference in weight between the two sides. To this end, the measuring member 140 may include a body 141 inserted into the body 120 and a measurer 142 protruding upward from the body 141, as shown in FIGS. 3 to 5 . Here, the body 141 may be mounted on the leveler rotating shaft 132b and the measuring member rotating shaft 132c of the horizontal member 130, as shown in FIG. The measuring member rotating shaft 132c rotates in the opposite direction around the self-rotating shaft 132b, and the body 141 rotates clockwise or counterclockwise around the measuring member rotating shaft 132c and the horizontal self-rotating shaft 132b. rotates in the direction of rotation. Of course, the measurer 142 rotates along the body 141 so that the horizontal member 130 rotates to the inclined side, that is, to the heavy side. Here, the first sensing unit 143 may be embedded in the front end of the measurer 142, which will be described later.

In addition, the plate 150 may be placed on both side plate fixing members 133, and a number weight 170 or weight weight 160 may be placed thereon. In addition, when the dish 150 goes down or goes up because one side is heavy, the dish 150 can always be kept level due to the leveling function of the dish fixing member 133.

In addition, the weight 160 may be manufactured in plural with a predetermined certain weight. For example, the weight 160 may be a weight corresponding to '1' of the number weight 170. In addition, the weights 160 may be made to a size that can contain at least 10 weights in one dish 150.

The numeric pendulum 170 is based on natural numbers, and may be manufactured by representing, for example, 0 to 10. At this time, the number weight 170 is manufactured to have a weight as much as the size of the corresponding number, and for example, the number weight 170 '1' is '10g (gram)', '2' is '20g' ... '10 ' can be produced as '100g'. If 10 weights 160 are placed on one plate 150 and 10 weights '10' are placed on the other plate 150, the horizontal member 130 is approximately level and the measurer 142 is approximately It is desirable to have a vertical position.

On the other hand, as shown in FIGS. 2 and 8 , the character 200 may be produced in a cute and cute appearance according to the age of the learner in order to arouse the interest of the learner. The character 200 is fixed to the pedestal 110 and may include a second sensing unit 210, a substrate 220, a speaker 230, a lamp 240, and a power supply unit therein.

The second sensing unit 210 may be installed to react with the first sensing unit 143 embedded in the tip of the probe 142 in FIG. 5 . The second sensing unit 210 may be installed to mutually react when the first sensing unit 143 approaches in a state in which both sides have the same weight and the measurer 142 is vertical. For example, the second sensing unit 210 and the first sensing unit 143 may include a magnet that generates a magnetic field change when they are close to each other. Of course, the second sensing unit 210 and the first sensing unit 143 may be manufactured to detect the distance when approaching or moving away.

The substrate 220 may be connected to the second sensing unit 210 with a wire to receive and determine a signal sensed by the second sensing unit 210 . The substrate 220 may provide an audio output signal to the speaker 230 and a lighting signal to the lamp 240 based on the determined data. Therefore, when the first sensing unit 143 and the second sensing unit 210 come close to the second sensing unit 210 and the board 220 connected by wires, it provides an audio output signal to the speaker 230, and the lamp 240 ) can provide a lighting signal.

The speaker 230 may be installed to receive an audio output signal from the substrate 220 and output audio. The speaker 230 may be installed to output various music, rhythms, etc. in various situations, including inducing learning, when a weight or number weight is placed on a plate, or when it is level or not level.

The lamp 240 may be installed to receive a lighting signal from the substrate and emit light. Like the speaker 230, the lamp 240 may also be installed to output various lights or flashes according to the situation in various situations. As shown in FIG. 2, these lamps 240 can be installed so that lights come from a crown, eyes, or a star on a character's chest.

The power supply unit may be manufactured to receive power from a battery, a mercury battery, or the like. In addition, the power supply unit may provide wires and power cords to receive external power. In addition, the power unit may further include an ON/OFF switch for cutting off and supplying power.
