Abstract

The utility model discloses a dual-purpose shoe used for walking and for skating. The dual-purpose shoe is composed of an ordinary shoe surface and a thick shoe sole provided with two concave grooves which are provided with four telescopic wheels. A spring pin arranged on both sides of the wheels is pressed downward or upward to move with a pitch so as to make the wheels extend out of the shoe sole or retract into the shoe sole; when the wheels are made to extend out of the shoe sole, the dual-purpose shoe becomes a roller-skating shoe; when the wheels are made to retract into the shoe sole, the dual-purpose shoe becomes an ordinary shoe.

Description

Dual-purpose shoe

The utility model relates to a kind of dual-purpose shoe, particularly a kind of dual-purpose shoe that can be used for walking again can roller skate.

Existing city shoe can only be used for walking; And roller skate can only be used for roller skate.If people think roller skate, have to change special-purpose roller skate, so both inconvenient, also uneconomical.

Task of the present utility model is that a kind of dual-purpose shoe that can be used for walking again can roller skate will be provided, and simple and easy to do, and the wearer can indiscriminately ad. as one wishes realize walking or slide (roller skate) according to the place situation.

Task of the present utility model is finished as follows: vamp is identical with city shoe, can be leather shoes, cloth shoes, plastic shoes or cotton-padded shoes, single footwear, sandals.Different just sole is thicker, the two pairs of wheels in front and back that can stretch have been installed on sole.If wheel is retracted in the sole, just become city shoe, just energy walking of wearer; If wheel is stretched out sole, just become roller skate, the wearer just can roller skate.Wheel flexible, it is also very easy to operate, and the wearer just can make wheel stretch out sole or indentation sole as long as pinch the bullet pin of the sub-both sides of pinch roller and upwards or the pitch-row that moves up with hand.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is an axonometric drawing of the present utility model.

Fig. 2 is the cutaway view of Fig. 1 along the A-A line.

Fig. 3 is bearing support among Fig. 2 (a 4) part drawing, and the pattern on the left side is by plastic injection-moulded shaping, and the pattern on the right is shaped by the sheet metal stamping-out.

Fig. 4 is the axonometric drawing with the supporting bullet pin (5) of plastic supporting frame.

Fig. 5 is the axonometric drawing with the supporting bullet pin (5) of metal support frame.

With reference to Fig. 1, before and after going up, sole (1) respectively opens a groove, wheels (2), (3) that resemble Fig. 2 structure are installed in the groove of front and back.

With reference to Fig. 2, bearing support (4) is fixed on the groove of sole (1) with binding agent (also available other methods of attachment).A wheel (6) (ball bearing that perhaps has dust-proof seal ring) is respectively adorned at the two ends of hollow shaft (8), in the circular hole of hollow shaft (8), load onto compression spring (9) and two bullet pins (5), bullet pin (5) inserts in the shrinkage pool (11) of bearing support (4) by the tension force of spring (9), make wheel reach the outside of sole, just become roller skate.If pressure bullet pin (5) is pinched with hand in the orientation by the arrow indication, the cylinder compression spring (9) of bullet pin (5) is entered in the hollow shaft, thereby make the cylinder of bullet pin (5) break away from shrinkage pool (11), pinching with hand then and unclamping hand when bullet pin (5) is moved upwards up to shrinkage pool (12) again, make bullet pin (5) under the tension force effect of spring (9) and in the insertion shrinkage pool (12), thereby make wheel be reduced to the sole the inside, just become city shoe.Move down if pinching bullet pin (5) with hand, broken away from bearing support (4), hollow shaft (8) and top wheel thereof etc. just can disassemble from footwear, so that maintaining.The whole operation process is very easy.

Be full of lubricating grease (10) in the circular hole of hollow shaft (8), when wheel (6) rotates,, just flow between axle and the wheel after lubricating grease is heated and play lubrication by the aperture on the axial wall (7) with the axle frictional heat.

Claims

1, the dual-purpose shoe formed of front-wheel [2] in a sole by former and later two grooves [1] and the groove thereof and trailing wheel [3] is characterized in that:

There are symmetrical upper and lower shrinkage pool [11], [12] in a bearing support [4] both sides, and hand is pinched bullet pin [5] compression spring [9], can make in bullet pin [5] the indentation hollow shaft [8], thereby break away from shrinkage pool [11], upwards moves and can enter shrinkage pool [12]; Can take wheel from footwear to moving down.

Respectively be drilled with a small sircle hole [7] on b hollow shaft [8] end walls, the lubricating grease [10] that is filled in hollow shaft [8] inner chamber can be by this orifice flow to lubricate between hollow shaft [8] and the wheel [6].

2,, it is characterized in that front and back wheel (2), (3) can reach sole (1) outside, also may compress into sole (1) the inside according to the dual-purpose shoe of claim 1 regulation.
