The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the drawings for explaining a dumbbell set according to embodiments of the present invention.

FIG. 1 is a view showing a set of dumbbells according to a preferred embodiment of the present invention. FIG. 2 is an enlarged perspective view of a dumbbell weights and a dumbbell fastening part in an enlarged scale in a dumbbell set according to a preferred embodiment of the present invention.

Referring to FIGS. 1 and 2, a dumbbell set according to a preferred embodiment of the present invention includes a dumbbell 110 having an insertion hole 111 passing through the center thereof; And a dumbbell bar (120) fastened to both sides of the dumbbell weight (110) through insertion holes (111) of the dumbbell weight (110). .

At this time, a first groove 112 is formed in the inner side of the insertion hole 111 of the dumbbell weight 110 along the direction of insertion of the insertion hole 111, and the first groove 112 is provided with RFID Tag 113 is provided.

The RFID tag 113 can be easily attached in the form of a sticker and a protective sheet 114 is formed on the RFID tag 113 to prevent the RFID tag 113 attached to the first groove 112 from being dirty or dropped. May be further attached.

A second groove 121 is formed on one side of the dumbbars 120 and a first fastener 122 is inserted and fixed in the second groove 121. The first fastener 122 is inserted into the second groove 121, And a first protrusion 123 protruded to correspond to the shape of the first groove 112 is formed on the upper side.

Generally, the dumbbell bar and the dumbbell iron material interfere with the radio frequency communication in the RFID system, so that it can be prevented through the first fastener 122 made of plastic.

A first RFID reader 124 is provided in the first protrusion 123 so that when the dumbbell 110 is fastened to the dumbbell 120 and the RFID tag 113 passes through the RFID tag 113, And reads the unique ID information from the reader 113.

At this time, the predetermined recognition distance is influenced not only by the frequency of the used RFID, but also by whether the RFID tag is an active tag or a passive tag, so an appropriate selection is necessary.

A third groove 125 is formed on the inner side of the second groove 121 on the same side as the second groove 121 on one side of the dumbbars 120. Inside the third groove 125, The second fastening hole 126 is also made of a plastic material through which a radio frequency (RF) can pass. On the upper side, the second fastening hole 126 is formed in the shape of the first groove 112 A second protrusion 127 protruding correspondingly is formed.

A second RFID reader 128 is provided on the second protrusion 127 to allow the dumbbell 110 to be engaged with the dumbbell 120. When the dumbbell 110 is inserted into the dumbbell 120, 113).

3 is a block diagram of a dumbbell bar according to a preferred embodiment of the present invention.

3, the dumbbell 120 further includes a microprocessor 129. The RFID tag 113 first passes through the first RFID reader 124 and then passes through the second RFID reader 128 The predetermined weight of the dumbbell weight 110 is extracted from the unique ID information read by the first RFID reader 124 and the second RFID reader 128 from the RFID tag 113. Then, The weight of the dumbbell weight 110 fastened to the dumbbell 120 is recorded.

On the contrary, when the RFID tag 113 first passes through the second RFID reader 128 and then passes through the first RFID reader 124, the microprocessor 129 transmits the unique ID information read from the RFID tag 113 The predetermined weight of the dumbbell weight 110 is extracted and the predetermined weight of the extracted dumbbell weight 110 is subtracted to record the total weight of the dumbbell weight 110 fastened to the dumbbell 120.

At this time, if only one of the first RFID reader 124 and the second RFID reader 128 is included and the RFID tag 113 passes through the first RFID reader 124 or the second RFID reader 128 an odd number of times, The weight of the predetermined dumbbell weight 110 extracted through the unique ID information of the first RFID reader 113 or the second RFID reader 128 is added to the total weight and the RFID tag 113 transmits the first RFID reader 124 or the second RFID reader 128 to the even- The weight of the predetermined dumbbell weight 110 extracted through the unique ID information of the RFID tag 113 may be subtracted from the total weight and recorded.

The weight of the dumbbell weight 110 fastened to the dumbbell bar 120 extracted from one side of the dumbbell 120 may be the same as the weight of the dumbbell weight 120. [ As a total weight of the actual dumbbell weight 110,

The dumbbell bar 120 may further include a motion sensor 130 and a display unit 131.

The motion sensor 130 is provided inside the dumbbell 120 to sense the motion locus and the acceleration of the dumbbell 120 and to measure the motion of the dumbbell 120 using the dumbbell set 100 of the user, Motion information can be extracted.

Therefore, although the combination of the acceleration sensor and the gyroscope is preferable for the motion sensor 130, it may be constituted by a combination of other sensors.

The display unit 131 is provided on one side of the dumbbell bar 120 and displays the total weight of the dumbbell weight 110 fastened to the dumbbell 120.

The display unit 131 may display text using a general LED panel or the like. The display unit 131 is provided in a donut shape along one side diameter of the dumbbell bar 120 as shown in FIG. 2, Accordingly, some of the total area may be marked to be filled with a specific color.

In addition, the microprocessor 129 compares the exercise information such as the exercise attitude, the exercise speed, and the exercise frequency analyzed through the motion locus and the acceleration of the dumbbell 120 received from the motion sensor 130 with predetermined target information It is preferable to control the display unit 131 to blink in a predetermined color or to display a warning phrase when the target information is exceeded or not reached.

At this time, in addition to the display unit 131, the dumbbell bar 120 may further include a vibration generating unit to vibrate with the display unit 131.
