Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a shoe for walking and skating whose sole can be kept clean and which is more convenient and safer in using.

2. Description of the Prior Art

In order to increase the functions of the shoes, a “sole of roller shoes” of TW Pat. No. 367879 (see FIG. 1) and a “shoe for walking and skating” of TW Pat. No. 400753 are known as prior arts. In these two disclosures, a conventional shoe is provided with

rollers

7 on the sole in a projecting or hidden mode, thereby creating the skating function of a shoe. However, the bottom of the holding groove 8 has to be open in order to store the rollers 7, thereby accumulating impurities and therefore causing malfunction of the rollers (e.g. the rollers are easily blocked by the impurities). Moreover, the pivot 71 of the rollers 7 is fitted with strong spring (not shown) so that the stored rollers won't fall down. However, it takes much effort to bring out the rollers in place for skating, and it's almost impossible for children to complete it. Also, although the skating function is reached, no braking device is present so that the use safety is not ensured.

SUMMARY OF THE INVENTION

It is a primary object of the present invention to provide a shoe for walking and skating in which the sole can be kept clean for preventing the rollers from malfunctions.

It is another object of the present invention to provide a shoe for walking and skating which is fitted with a braking element for ensuring the safety in use.

It is a further object of the present invention to provide a shoe for walking and skating which is easy, convenient and effortless in operation and in use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

First of all, referring to FIGS. 2 through 6, the shoe for walking and skating in accordance with the present invention includes a shoe [0025] 1, a locating plate 2, two locating members 3 a, 3 b, two rollers 4 and a brake 5.
The shoe [0026] 1 has a sole 11 provided with a front and a rear holding grooves 12, 13.
The bottom of the locating [0027] plate 2 includes a front and a rear locating frames 21, 22 respectively corresponding to the front and rear holding grooves 12, 13.
The locating [0028] members 3 a, 3 b are respectively fixed in the front and the rear locating frames 21, 22 by means of screws 23. Each of the locating members 3 a, 3 b has a button 31 at either side thereof for pushing a pivoting element 32 to control the axial movement of a locating pin 33 while a cap 34 is used to fix the button 31, the pivoting element 32 and the locating pin 33. Besides, a compression spring 35 is interposed between the cap 34 and the locating pin 33, thereby creating a resilient force required by the locating pin 33 in returning to its original position. Moreover, a mounting bar 36 with an elongated groove 361 is movable ups and downs and mounted on either side of the locating members 3 a, 3 b.
The [0029] rollers 4 are mounted on the elongated grooves 361 of the mounting bars 36 by means of screws 41. In addition, an upper and a lower locating holes 42, 43 are disposed at both sides thereof so that the locating pin 33 can be inserted into either of the upper and a lower locating holes 42, 43 for fixing the rollers 4 in place.
The brake [0030] 5 has a locating housing 51, a locating rod assembly 52 and a braking piece 53. The locating housing 51 together with the rear locating member 3 b is arranged in the rear locating frame 22. The braking piece 53 outwardly projects or is hidden inside by means of the locating rod assembly 52 together with an upper and a lower fixing hole 531, 532.
The sole [0031] 11 is provided with a plurality of through holes 14 at positions corresponding to each of the buttons 31 and the locating rod assembly 52.
In addition, the [0032] braking piece 53 serving as a contact body 533 with the ground is made of a high-abrasive plastic material.
Moreover, a [0033] compression spring 37, 54 is respectively arranged in the locating members 3 a, 3 b and the locating housing 51 of the brake 5.
Furthermore, the locating [0034] rod assembly 52 is composed of a sleeve 521, a spring 522 and a fixing pin 523. The spring 522 fitted to the inside of the sleeve 521 supports against the fixing pin 523. And a domed head 524 is mounted on the outer end of the fixing pin 523 for pulling.
Referring to FIG. 4, the [0035] rollers 4 and the braking piece 53 are located for a skating mode. At this time, the rollers 4 are directed downwardly and the braking piece 53 projected outwardly. With reference to FIGS. 5 and 6, the rollers 4 are located by means that the locating pin 33 is inserted into the upper locating hole 42 while the braking piece 53 is located by means that the fixing pin 523 of the locating rod assembly 52 is inserted through the upper fixing hole 531. As shown in FIG. 7, in changing the locating mode of the rollers 4 and the braking piece 53, the button 31 is pressed down to retract the locating pin 33 by means of the pivoting element 32, thereby creating a releasing state. Meanwhile, the fixing pin 523 of the locating rod assembly 52 is pulled outwardly to release the braking piece 53.
Thereafter, as shown in FIGS. 8 and 9, when the [0036] rollers 4 is released, they will fall down along the elongated groove 361 of the mounting bar 36 (while the mounting bar 36 also falls down) so that the rollers 4, as shown in FIGS. 10 and 11, have the revolving space. After the rollers 4 are revolved, as shown in FIG. 12, the locating pin 33 restores itself by means of the resilient force of the spring 35 in a locked state. Meanwhile, the locating pin 33 is inserted into the lower locating hole 43 to hide the rollers 4 in place. Besides, the fixing pin 523 of the braking piece 53 also restores itself by means of the resilient force of the spring 522 in a locked state. Meanwhile, the fixing pin 523 is inserted into the lower fixing hole 532 to hide the braking piece 53 in place, as shown in FIGS. 13 and 14. Accordingly, a walking function is created. To the contrary, the rollers 4 and the braking piece 53 can be changed from the hidden state to the exposed state. The method thereof is similar so that it won't be described more hereinafter.
As shown in FIGS. 15 and 16, another embodiment of the locating [0037] rod assembly 52′ is formed as a press switch, and the fixing pin 523′ is telescopic to located the braking piece 53 in place. Meanwhile, the arrangement position of the braking piece 53 is fixable and adjustable as well.
Accordingly, no matter for performing the skating or the walking functions, the front and [0038] rear holding grooves 12, 13 of the sole 11 are sealed by the top rim of the rollers 4, thereby preventing the foreign bodies from entering into the front and rear holding grooves 12, 13 so that the cleanness in the front and rear holding grooves 12, 13 is ensured. In addition, it is avoidable that the rollers 4 are blocked by impurities, causing malfunctions. Moreover, the braking piece 53 is arranged for securing the safety in use. Moreover, it is only required to press the button 31 to push the pivoting element 32 for an axial movement of the locating pin 33, thereby releasing the locating pin 33 from the upper or the lower locating holes 42, 43. Thereafter, the rollers 4 is revolving to change the arrangement position. At the same time, the position of the braking piece 53 can also be adjusted by the locating rod assembly 52. Again, when the rollers 4 and the braking piece 53 are received in the holding grooves 12, 13 and the locating housing 51, they can be taken out smoothly by the compressed spring 37, 54 without the conventional blocking problems. Therefore, it's very convenient to change the locating direction of both rollers 4 while the locating position of the braking piece 53 can also be changed by the locating rod assembly 52 so that the present invention is convenient in use.
Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims. [0039]
