Description
- 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 therollers 7, thereby accumulating impurities and therefore causing malfunction of the rollers (e.g. the rollers are easily blocked by the impurities). Moreover, thepivot 71 of therollers 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. - 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.

- FIG. 8 is a schematic drawing of the first step in hiding the rollers of the present invention;
- FIG. 9 is a sectional view taken from the line C-C of FIG. 8;
- FIG. 10 is a schematic drawing of the second step in hiding the rollers of the present invention;
- FIG. 11 is a schematic drawing of the third step in hiding the rollers of the present invention;
- FIG. 12 is a partially sectional view of the embodiment of the present invention in walking mode;
- FIG. 13 is a schematic drawing of a braking piece in an exposed (projecting) state;
- FIG. 14 is a schematic drawing of the braking piece in a hidden state;
- FIG. 15 is a first schematic drawing of another embodiment of a locating rod assembly of the present invention; and
- FIG. 16 is a second schematic drawing of another embodiment of the locating rod assembly of the present invention.
- First of all, referring to FIGS. 2 through 6, the shoe for walking and skating in accordance with the present invention includes a shoe1, a locating
plate 2, two locatingmembers 3 a, 3 b, tworollers 4 and a brake 5. - The shoe1 has a sole 11 provided with a front and a
rear holding grooves - The bottom of the locating
plate 2 includes a front and a rear locatingframes rear holding grooves - The locating
members 3 a, 3 b are respectively fixed in the front and the rear locatingframes screws 23. Each of the locatingmembers 3 a, 3 b has abutton 31 at either side thereof for pushing apivoting element 32 to control the axial movement of a locatingpin 33 while acap 34 is used to fix thebutton 31, thepivoting element 32 and the locatingpin 33. Besides, acompression spring 35 is interposed between thecap 34 and the locatingpin 33, thereby creating a resilient force required by the locatingpin 33 in returning to its original position. Moreover, amounting bar 36 with anelongated groove 361 is movable ups and downs and mounted on either side of the locatingmembers 3 a, 3 b. - The
rollers 4 are mounted on theelongated grooves 361 of themounting bars 36 by means ofscrews 41. In addition, an upper and a lower locatingholes pin 33 can be inserted into either of the upper and a lower locatingholes rollers 4 in place. - The brake5 has a locating
housing 51, a locatingrod assembly 52 and abraking piece 53. The locatinghousing 51 together with the rear locatingmember 3 b is arranged in the rear locatingframe 22. Thebraking piece 53 outwardly projects or is hidden inside by means of the locatingrod assembly 52 together with an upper and alower fixing hole - The sole11 is provided with a plurality of through
holes 14 at positions corresponding to each of thebuttons 31 and the locatingrod assembly 52. - In addition, the
braking piece 53 serving as acontact body 533 with the ground is made of a high-abrasive plastic material. - Moreover, a
compression spring members 3 a, 3 b and the locatinghousing 51 of the brake 5. - Furthermore, the locating
rod assembly 52 is composed of asleeve 521, aspring 522 and afixing pin 523. Thespring 522 fitted to the inside of thesleeve 521 supports against thefixing pin 523. And adomed head 524 is mounted on the outer end of thefixing pin 523 for pulling. - Referring to FIG. 4, the
rollers 4 and thebraking piece 53 are located for a skating mode. At this time, therollers 4 are directed downwardly and thebraking piece 53 projected outwardly. With reference to FIGS. 5 and 6, therollers 4 are located by means that the locatingpin 33 is inserted into the upper locatinghole 42 while thebraking piece 53 is located by means that thefixing pin 523 of the locatingrod assembly 52 is inserted through theupper fixing hole 531. As shown in FIG. 7, in changing the locating mode of therollers 4 and thebraking piece 53, thebutton 31 is pressed down to retract the locatingpin 33 by means of thepivoting element 32, thereby creating a releasing state. Meanwhile, thefixing pin 523 of the locatingrod assembly 52 is pulled outwardly to release thebraking piece 53. - Thereafter, as shown in FIGS. 8 and 9, when the
rollers 4 is released, they will fall down along theelongated groove 361 of the mounting bar 36 (while themounting bar 36 also falls down) so that therollers 4, as shown in FIGS. 10 and 11, have the revolving space. After therollers 4 are revolved, as shown in FIG. 12, the locatingpin 33 restores itself by means of the resilient force of thespring 35 in a locked state. Meanwhile, the locatingpin 33 is inserted into the lower locatinghole 43 to hide therollers 4 in place. Besides, thefixing pin 523 of thebraking piece 53 also restores itself by means of the resilient force of thespring 522 in a locked state. Meanwhile, thefixing pin 523 is inserted into thelower fixing hole 532 to hide thebraking piece 53 in place, as shown in FIGS. 13 and 14. Accordingly, a walking function is created. To the contrary, therollers 4 and thebraking 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
rod assembly 52′ is formed as a press switch, and the fixingpin 523′ is telescopic to located thebraking piece 53 in place. Meanwhile, the arrangement position of thebraking piece 53 is fixable and adjustable as well. - Accordingly, no matter for performing the skating or the walking functions, the front and
rear holding grooves rollers 4, thereby preventing the foreign bodies from entering into the front andrear holding grooves rear holding grooves rollers 4 are blocked by impurities, causing malfunctions. Moreover, thebraking piece 53 is arranged for securing the safety in use. Moreover, it is only required to press thebutton 31 to push the pivotingelement 32 for an axial movement of the locatingpin 33, thereby releasing the locatingpin 33 from the upper or the lower locating holes 42, 43. Thereafter, therollers 4 is revolving to change the arrangement position. At the same time, the position of thebraking piece 53 can also be adjusted by the locatingrod assembly 52. Again, when therollers 4 and thebraking piece 53 are received in the holdinggrooves housing 51, they can be taken out smoothly by thecompressed spring rollers 4 while the locating position of thebraking piece 53 can also be changed by the locatingrod 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.
