Abstract
A shoe sole includes a sole body having a shock absorbing unit integrally connected to a recess in the sole body and a fabric is attached to the sole body. The shock absorbing unit extends from a hole defined through the fabric. The buttering unit includes a bladder in which the elastic Polyurethane is received and a flange extends from a periphery of the bladder so as to be engaged with the recess in the sole body.
Description
- The present invention relates to a shoe sole that includes an integrated shock absorbing unit which is embedded in the sole.
- A
conventional shoe sole 10 with ashock absorbing unit 100 is disclosed in FIG. 1 and theshock absorbing unit 100 is glued to the desired position on theshoe sole 10. Theshock absorbing unit 100 and the shoe sole are manufactured in separate processes so that the manufacturing cost is high. Besides, theshock absorbing unit 100 tends to be peeled off from the sole after being used for a period of time. Anothershoe sole 10′ and theshock absorbing unit 100′ are disclosed in FIG. 2 and theshock absorbing unit 100′ is made of foam material which protrudes from the surface of the sole 100′. The foam madeshock absorbing unit 100′ has limited shock absorbing feature and the gaps in theshock absorbing unit 100′ decrease gradually after being used for a period of time so that it becomes a stiff protrusion and makes uncomfortable touch to the feet. - The present invention intends to provide a shoe sole that includes a shock absorbing unit embedded in the sole without using glue. The shock absorbing unit is made of gel or a bladder with fluid filled therein so as to provide satisfied shock absorbing feature.
- In accordance with one aspect of the present invention, there is provided a shoe sole which comprises a sole body having a shock absorbing unit integrally connected to a recess in the sole body. The shock absorbing unit is made of Polyurethane and is elastic so as to absorb shocks. A fabric is attached to the sole body and the shock absorbing unit extends from a hole defined through the fabric.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
- FIG. 1 is an exploded view to show a conventional shoe sole with a shock absorbing unit;
- FIG. 2 is an exploded view to show a conventional shoe sole with a shock absorbing unit;
- FIG. 3 shows steps of the method for making the shoe sole of the present invention;
- FIG. 4 is a perspective view to show the mold assembly for making the shoe sole of the present invention;
- FIG. 4A shows a shock absorbing unit and a fabric is displaced in the first cavity in the first mold;
- FIG. 5 shows the parts composing the shoe sole of the present invention;
- FIG. 5A is a cross sectional view to show the shoe sole of the present invention;
- FIG. 6 is a perspective view to show the shoe sole of the present invention;
- FIG. 7 shows the shoe sole of the present invention in a shoe and pressure is applied to the shock absorbing unit, and
- FIGS. 8 and 9 show the shock absorbing unit are located at different positions of the shoe sole.
- Referring to FIGS. 3 and 4, the method for making a shoe sole of the present invention comprises the following steps which are:
- step 1: displacing a
shock absorbing unit 31 in afirst cavity 411 defined in afirst mold 41; - step 2: putting a
fabric 32 in thefirst cavity 411 and thefabric 32 having anaperture 320 through which theshock absorbing unit 31 is extended as shown FIG. 4A; - step 3: pouring Polyurethane in a
second cavity 421 defined in thesecond mold 42; and - step 4: overlapping the
first mold 41 onto thesecond mold 42 and heating the Polyurethane to form asole body 30 with afabric 32 and ashock absorbing unit 31. - The
second mold 42 includes anetted area 421A defined in thesecond cavity 421 and thenetted area 421 includes ridges crossing over with each other, such that when thesole body 30 is removed from themold assembly 40, as shown in FIGS. 5, 5A and 6, thesole body 30 includes a plurality ofapertures 33 for ventilation and theshock absorbing unit 31 is located at the heel portion. - The
sole body 30 includes ashock absorbing unit 31 integrally connected to arecess 34 in thesole body 30 and theshock absorbing unit 31 is elastic. Theshock absorbing unit 31 includes a bladder in which the elastic Polyurethane or fluid is received. Aflange 312 extends from a periphery of the bladder and is engaged with therecess 34 in thesole body 30. - As shown in FIG. 7, the
shoe sole 30 is received in ashoe 20 and the pressure applied to theshock absorbing unit 31 at the heel portion of the foot deforms theshock absorbing unit 31 so as to reduce the pressure that applies to the foot. - FIGS. 8 and 9 show the
shock absorbing unit 31 can be located at different positions of theshoe sole 30. - The
shock absorbing unit 31 can be made by Polyurethane or Ethylene Vinyl Acetate and it can be used in wrist protectors, shin guards or any exercise pad. Theshock absorbing unit 31 can include TPU, TPR or PVC soft material in the bladder. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
