Description

A Sit-ups apparatus < RTI ID = 0.0 >

The present invention relates to a sit-up exercising apparatus, and more particularly to a sit-up exercising apparatus having an automatic measuring function for the number of times of sit-up raising.

The conventional sit-up raising exercise apparatus is provided with a photosensor on a support rod as disclosed in Registration No. 20-0334044, and detects the state of the upper body and measures the number of sit-up raises. However, such a sit-up exercising apparatus is disadvantageous in that the support rods provided on the side of the user are liable to be shaken because the support rods for the optical sensor are required to be installed, and errors in the number of times of sit-up raising are frequently caused by such shaking. Also, due to the nature of the optical sensor, it is affected by the clothes of a specific color (black), so it is troublesome to pay attention to the color of the clothes.

The sit-up exercise apparatus of the prior art includes not only an optical sensor but also a separate body contact switch in order to increase the accuracy of measurement. Such a fitness device is a configuration in which a switch is provided to be exposed to a mat member for contacting with the back of the body, and there is inconvenience that the user has to physically contact the body of a person. When using the fitness device for a long time, pain occurs due to frequent contact between the switch and the body There was also a problem. Furthermore, when the user is doing sit-ups at a high speed, the user often fails to press the switch precisely, thereby decreasing the accuracy of the measurement frequency.

In order to solve such a problem, Registration Apparatus No. 0415339 discloses a exercising apparatus for measuring the number of sit-ups by providing a contact sensor on a knee and a back part. However, it is difficult to precisely measure the number of times the sit-up is not performed if the knee-to-back contact is not performed correctly or the contact is difficult when the measurement is performed at a high speed without considering the inconvenience of attaching and removing the contact sensor to the knee. There was still a problem of poor accuracy.

The object of the present invention is to provide a sit-up exercise apparatus which is easy to use and has improved accuracy in automatic measurement of the number of times of sit-ups.

In order to solve the above-mentioned object of the present invention, there is provided a sit-up exercise device comprising: a mat member having a user's body and having a lower body seating portion and an upper body seating portion; And a control / display panel installed on one side of the mat member and displaying the number of times of sit-ups, the frame member supporting the frame member, the leg support member supporting the legs of the user, A non-contact type electrostatic capacity sensor installed on the upper body seating part for sensing a user's back and an optical sensor installed at an angle to the control / display panel for sensing a user's head, And counts the number of times the sit-up is performed only when the user's head is detected by the optical sensor.

The control / display panel includes a time display period for displaying a time for performing sit-up, a number display for displaying the number of sit-ups, a memory for storing information recorded in the time display period and the number display, A first switch for turning on / off or resetting, a second switch for starting the counting of time of the sit-up and counting of counts, an optical sensor for detecting the head of the user, and a controller for adjusting the time table timing, the count indicator, .

And a battery installed in the frame member to supply power to the control / display panel.

It is preferable that the optical sensor is installed to be inclined upward at an angle of 10 to 45 degrees with respect to the horizontal line.

The controller may further display the consumed calories of the user by using the number of times and the number of times and the time displayed at the time of the time.

As described above, the sit-up exercising apparatus of the present invention is a capacitive sensor that can detect the human body within 5 cm without contact with the color without affecting the color, and detects the back of the user. Therefore, Automatic measurement is possible, and the user's head is sequentially sensed by the tilted optical sensor and the number of times is counted, so there is an advantage that the number of times of sit-up can be accurately measured.

In addition, since the optical sensor is inclined upwardly without providing a separate support rod, the entire structure of the exercise machine can be simplified, and only the head is sensed, so that the influence of the color or the material of the clothes is small.

The sit-up exercising apparatus of the present invention may include a memory unit for displaying the exercise time and the number of times and managing the exercise history of the exercise apparatus. The calorie consumed by the exercising time and the number of times may be calculated and displayed It has the advantage of being able to grasp the effect of own exercise in real time.

Further, by providing the battery mounting space of the frame member and installing the battery, the battery can be used for a long time without a power source by using a high capacity lithium battery.

In addition, since the amount of calories consumed is automatically displayed, there is an advantage that the amount of exercise can be quantitatively confirmed after the end of the exercise.

The capacitance sensor 42 is connected to the controller 13 and detects a change in capacitance of the capacitance sensor 42 when the user touches the body or approaches within 5 cm and is transmitted to the controller 13. Therefore, the capacitance sensor 42 can sense even if the body and the capacitance sensor 42 are not in contact with each other by wearing thick clothes without being influenced by the clothes color that the user wears.

The frame member 14 supports the mat member 12 and has a plurality of ribs 21 connected to a rectangular frame 19 of the same size as the mat member 12. [ A battery mounting portion 11 on which a battery 32 is mounted is formed on one side for supporting the lower body mounting portion 30. The battery 32 is preferably a high capacity lithium battery. Therefore, the sit-up exercising apparatus 10 can be operated by using the battery even in the absence of the power source.

The leg support member 36 is adjustable in height by the adjustment knob 40 and supports a user's leg, and is generally well known in a sit-up exercising mechanism, and thus a detailed description thereof will be omitted.

The control / display panel 16 is provided on the lower body seat 30 of the mat member 12 and is inclined by θ with respect to the horizontal line as shown in FIG. Here, theta is preferably in the range of 10 degrees to 45 degrees. The control / display panel 16 can be installed lower than the user's face (head) by tilting the control / display panel 16, so that the control / display panel 16 is less shaky, .

1 to 3, the control / display panel 16 includes a time display unit 20, a count display unit 22, a control unit 13, an optical sensor 18, a first switch 24, A memory unit 26, and a memory unit 38 are provided. The time display period 20 is a display device for displaying the time from when the user starts to sit-up to the end. When the user presses the second switch 26, the counting is started. The set time for counting the sit-ups can be set to 60 seconds or 30 seconds as a time set in the control unit at the time of manufacturing the product, and can be set when the consumer wants a specific time. Also, although not shown, a setting button may be additionally provided so that a separate time can be set in seconds, so that the user can set or change the set time. The number indicator 22 displays the number of sit-ups in the controller 13 the number of times recognized by the capacitive sensor 42 and the light sensor 18. The control unit 13 recognizes the detection by the optical sensor 18 and the capacitance sensor 42 and displays it in numerals on the time period indicator 20 and the count indicator 22 and outputs the first and second switches 24 and 26 And a memory unit 38 to control the overall system operation. The optical sensor 18 is installed on the surface of the control / display panel 16 and senses the upward direction by an angle of? With respect to the horizontal direction as shown in FIG. Therefore, even if the height is low, the user's head (face) can be detected. The first switch 24 is a switch having an on / off function and a reset function, and is used when the user turns on or off the power, or resumes by resetting the displayed screen. When the second switch 26 is pressed by the switch for notifying the start of the second switch 26, the set time and the number of times are counted, and when the set time is finished, the counting of the number is stopped. The memory unit 38 records the contents displayed on the time display 20 and the number display 22. When the first switch 24 or the second switch 26 is pressed, the control unit 13 displays the time, And automatically stores the date and time used together in the memory unit 38. Accordingly, the user can confirm the contents stored later through the memory unit 38, and can confirm his / her own exercise record by time of day. The memory unit 38 may be configured as an SD memory storage device, and a slit (not shown) may be formed in the control / display panel 16 so that the SD memory storage device can be inserted or removed from the slit. In this configuration, the user can connect his / her SD memory storage device to his / her computer and check his / her exercise record.

The consumed heat quantity indicator 15 may be configured as a separate display window or may simultaneously display the time, the number of times, and the consumed heat quantity in one display window, and the contents stored in the memory unit 38 may be checked in real time It can also be configured to be. The calorie consumption is calculated using the use time and the number of sit-ups in the control unit 13. [ The more times you sit-up a lot of times in a short time, the more calories you will need.

Hereinafter, the operation of the sit-up raising exercise device 10 according to the above-described embodiment will be described in detail with reference to FIGS. 1 to 3. FIG.

When the user sits on the mat member 12 and then presses the first switch 24, power is supplied from the battery 11. When ready to start sit-up, the user presses the second switch 26 and starts to sit-up. At the same time that the second switch 26 is pressed, the control unit 13 displays the use time at the time of the time display 20. Allow 5 seconds of preparation time to start counting and allow user to prepare for measurement. After 5 seconds, buzzer sounds to inform start of measurement. Regardless of the number of sit-ups, the time displayed on the time schedule 20 continues to rise until the set time ends. The time of the timetable period 20 is preferably expressed in seconds. 2, when the user's back is in contact with the mat member 12, the controller 13 detects the presence of the user through the electrostatic capacitance sensor 42 provided on the mat member 12. When the user's face (head) is detected by the optical sensor 18 installed on the control / display panel 16 after being sensed by the electrostatic capacitance sensor 42, the controller 13 recognizes the user's face as one time, (22). If the electrostatic capacity sensor 42 detects the user but the optical sensor 18 does not detect the user, the control unit does not recognize the user as the number of times of sit-up. Also, since the number of times of counting is counted only when the head or face portion is secondarily sensed by the optical sensor 18, the number of accurate sit-ups is counted.

When the sit-up counting is ended, the control unit 13 automatically stores the last time and the number of times in the memory unit 38 together with the date and time of use. Therefore, the user can take out the memory unit 38 at any time and inquire and manage his / her exercise at any time by using a program installed in a separate computer. When the control / display panel 16 is configured as shown in FIG. 4, the controller 13 calculates the amount of consumed heat through the number of times of sit-up raising and the time, displays it on the display window and stores it in the memory unit 38. Accordingly, the user can not only check the calories consumed by the user in real time, but also can take out the memory unit 38 and check the consumed calories of the user by the date on a separate computer installed with the program. Further, although not shown, a program for confirming the contents of the memory may be provided in the sit-up exercising device, and the user may check or manage his or her own exercise record through a display window or a monitor installed separately.
