Abstract

PURPOSE:To compute the size of a frame which fits the user's physical constitution quickly and accurately, by providing an operation and display device for frame sizes, which computes a seat angle, SAR, and the like, based on each detected signal that is inputted from a riding attitude detecting device, and displays the result. CONSTITUTION:Position detectors detect a horizontal distance X1 from a hanger part 28 to a handle supporting part 23, a height Y1 from the hanger part 28 to the handle supporting part 23, a horizontal distance X2 from the hanger part 28 to a saddle supporting part 39, and a height Y2 from the hanger part 28 to the saddle supporting part 39. Then the detected signal from each position detector is sent to an A/D converter 43 through a main control box 42 and converted into the digital signal. The result is inputted and stored in an operation and display device 44. The operation and display device 44 performs the operation in accordance with programs. The operations are sequentially performed in accordance with the programs. At this stage, the kind of a bicycle, the diameter of a wheel, and the like, which are requested by the user are inputted. The size of the frame which fits the user's physical constitution is computed. The result is stored in the operation and display device 44. A frame drawing is outputted together with the computed result.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bicycle frame size calculation device.

A conventional pedaling device for improving physical strength is shown in Figure 1. (

The second saddle support part is inserted into the dragon (the sword is fixed to the second saddle support part (CI), and the second saddle is fitted into the supporting leg (75) so as to be movable in the vertical direction. The first handle support part fA+ is a second handle support part fitted into the first handle support part (I) so as to be movable in the horizontal direction, and fi+ is fixed to the second handle support part (I). Shida)

Place it in place by tightening and fixing each screw)~((sha), then sit down on the seat, and fit the handle.
The system is designed to help improve physical strength by gripping the pedal, stepping on the pedal (C1), and rotating the pedal axis (C2) to resist the pedal effort.

The purpose of the pedaling device is to improve physical strength, and it is the most popular of all the pedaling devices available on the market. It can also be used as a riding posture detection device to determine if -i (♀) matches your physique. In that case, after positioning the saddle (fl) and handle (i+), measure the distance between each part by applying a tape measure. (The rubber is eight, the seat angle, the gas star angle, etc. are missing.) It is necessary to calculate using a manual calculator etc. based on the above measurement results, which is inefficient. The user is seated on the handle (F), grips the handle (O), steps on the handle (C1), and rotates the handle (C2). With no pedal force resistance (condition close to actual driving condition''r-)-
Since it is not possible to position the reedle (1) or the handle fi+, there is a problem in that it is difficult to hold the riding position accurately.

The present invention addresses the above-mentioned problems.The user sits on the saddle on the saddle support part, grips the handle on the handle support part, and steps on the hanger part to provide pedal force resistance.
While rotating the dull shaft, the hanger section is moved horizontally, the handle support section is moved vertically and horizontally, and the saddle support section is moved downwards by the respective movement drive devices. After determining the optimal riding posture that suits your physique, determine the horizontal distance from the hanger to the handle support (X1), the height from the hanger to the handle support (Yl), and the horizontal distance from the hanger to the handle support (Yl). Based on the distance x2, the height Y2 from the hanger part to the saddle support part, the seat angle S A B, the frame size FS and This invention relates to a bicycle frame dimension calculation device characterized by comprising a frame dimension calculation/display device for calculating caster angle CAR top pizo dimension TT, front center LI'C, etc. and displaying the results.

1) (see 1 in Figure 11) is calculated from the wheel diameter of the bicycle to be used, the dimensions of the fork shoulder, lug, head accessories, etc. 2).

The above calculations are performed sequentially according to the program, but at that stage, the user's requests such as 7) car model, wheel diameter, etc. are also input, and the frame dimensions that match the user's physique are calculated, and the results are calculated and displayed. stored in the device (4a), and
A frame diagram is output as a result of the calculation. Next, when the user desires a commercially available bicycle, the calculation/display device (44) searches for a commercially available bicycle whose frame size is close to the calculated frame size from among the already stored data group of commercially available bicycles. The procedure is shown in Figure 12.

Like Sunzu Ill, you can select a large car model (such as Sports Subaru, Junius D Sorts Heavy, or Keikai Ichi), and then use the next fake (like Ill) to select a smaller model of the selected car. Subspecies (for example, for sports heavy trucks, road, etc.
Search by car type (such as general sports...) V2,
Next, as in (Ill), search if your height is within the appropriate height for rotation ■, and then as in (IV), search for 90 to 1 of your desired budget.
Search by price within 10cm, then search by desired hue range (1~2) as in (■), and then display the search results as shown in (Vl).As needed (Vl) Perform a secondary search for the top tP1, ■Manufacturer name, ■Frame size, ■Wheel diameter, ■Frame shape, ■Handlebar shape, ■Shift speed f4j'' number, and the result will be like the 0 button. Is displayed.

Next, the present invention will be explained in detail. (II. Conventionally, as mentioned in -1, the position of each part was measured artificially using a tape measure, and the bicycle frame dimensions were separately divided, but in the present invention, the movement of each part was measured manually. The position of each part is automatically moved to the torso side by an electric motor, and the position of each part is automatically adjusted from the position of riding to riding. It is easier to work with +11I dimensions, (■) It has not been easy for bicycle users to make custom-made frames whose dimensions depend on their physique, but the present invention solves the above problem. It is constructed like this, so you can easily adjust the frame size to match your physique! ) to be, to be. (1n) When selecting a bicycle that suits the user's physique from among commercially available bicycles, it is extremely difficult to know all the commercially available bicycles that are on the market. Easy and good. It's easy to choose one that suits your physique from among them. However, in the present invention c'1, all the data Y rN M,・
Display device (44) is stored, and it is possible to search the user's requests, wishes, and frame dimensions based on the riding posture from all the data of the above-mentioned commercially available bicycle J,
This makes it easier for users to select a commercially available bicycle.

(IV) Various types of commercially available rotating heavy handles and saddles (V) can be adjusted to J size without any manual labor, so the riding posture can be determined accurately.

(■ Since the pedal force resistance applied to the R barrel axis (2 (g) can be changed, it is possible to achieve a condition close to the actual driving condition, and in this respect, the riding posture can be determined accurately. effective.

Is this the invention? Although the embodiments have been described, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications may be made without departing from the spirit of the present invention. For example, if a torque detection device is installed on the shaft that interlocks with the pedal shaft, will it be possible to measure the power of the pedal effort? Calculate and
This may be added to the evaluation of riding posture and frame dimensions. It is also possible to measure the saddle body L using a body pressure measurement sensor attached to the surface of the saddle, and add this force to the evaluation of the riding posture and frame dimensions. ,-!
