Design Of Outer Ear Type Shallow Enclosure Shoes

The outer ear type shoe has a design principle of "Li Huai looks for the inside, and looks for the outside."

It is also suitable for outer ear type shallow shoe.

1. finished product drawing

As shown in figure 2-2-8, this shoe is the same product as the first three shoes.

When designing the outer ear shoe, no matter whether the tongue is broken or not, double line pick up method is adopted.

If the tongue is broken, use the A1/Ao line design; if it is a continuous tongue, use the A2/AO line design.

The tongue of this picture is kept open.

 

The front point of the shoe ear has the difference between the inside and outside, and the lower part of the front point is also different from the inside and outside. It should correspond to the inside and outside arms of the enclosure.

2. structure design drawing

The structure design of outer ear type shallow enclosure shoes is shown in figure 2-2-9.

 

(1) first design the length of the ear of the shoe and the shoe of the rear shoe in the 1/2VE position, and design two eye positions.

The front point of the shoe ear is near the point O, and the lower end of the shoe ear is tilted backwards.

The front point of the shoe ear should have the difference between the inside and outside, the difference between the front and the back, and the lower segment only makes the difference between the front and the back.

The outline of the shoe is designed, the position of the rear heel is designed, and the false line and the lock line position of the shoe ear are designed.

Connect the back line.

(2) the design of shoe covers and girth is used to intersect with EV extension line.

Point, use the copy board to draw the outline of the shoe cover on the straight line in the back line, then connect it to the straight line of the surround strip, and the termination point is O'.

From the point of J', supplement the 1/3 difference. Draw the outer outline of the fence with the replica board on the back curve and follow the O' point.

The location of the O'point is a general position.

Then make the difference between the inside and outside of the shoe cover and the enclosure.

The front line of the fence is connected with the AJ'line as the center line of the girth.

The vertical line of the center line is corrected along the circular line of the fence, and the amount of loss is supplemented by the bottom tension.

As shown in figure 2-2-9, the shadow shows.

Finally, the contour of the bottom rib and the difference between inside and outside are designed.

Mark the rules on the shoe cover and do not need to turn around again. When the double line takes off, the front gang has been rotated, and the parts on the back are sticking to the last.

The basic model of the shoe cover is shown in figure 2-2-10.
