A schematic diagram of the operation of the locking mechanism of the height shoe; and FIGS. 7A-7C illustrate a continuous operation of the shoe with adjustable heel height according to the embodiment.

The embodiments of the present invention are disclosed in the following drawings, and for the purpose of clarity However, it should be understood by those skilled in the art that the details of the invention are not essential to the details of the invention. In addition, some of the conventional structures and elements are shown in the drawings in a simplified schematic manner in order to simplify the drawings. In addition, for the convenience of the reader, The dimensions of the various elements in the drawings are not drawn to scale.

1A to 1B are schematic diagrams showing a simple operation of the shoe 10 capable of adjusting the height of the heel according to an embodiment of the present invention. As shown in FIGS. 1A and 1B, the shoe 10 of the adjustable heel height of the present embodiment includes a shoe board 100 and a retractable heel 200. The shoe board 100 is used to carry a single foot of the human body (not shown). The shoe board 100 includes a front bracket 110, a rear bracket 120 and a linkage 300. The rear bracket 120 is coupled to one side of the front bracket 110 in a reversible manner (e.g., via a pivot or crease). The retractable heel 200 has a long column shape and the retractable heel 200 is capable of changing its length due to expansion and contraction. One end of the retractable heel 200 is pivotally connected to one side of the rear bracket 120 with respect to the front bracket 110. The front bracket 110 has a protruding rib 111 that projects outward from the side of the front bracket 110. The spacing between the linking member 300 and the rear bracket 120 is maintained, and the opposite ends of the linking member 300 are respectively pivotally connected to the protruding rib 111 of the front bracket 110 and the retractable heel 200. Thus, the protruding rib 111, the rear bracket 120, the retractable heel 200 and the linking member 300 together define a link restraining mechanism (such as a four-link structure).

In this way, when the link restraint mechanism is interlocked, for example, when the rear bracket 120 is reversed relative to the front bracket 110, the retractable heel 200 of the present embodiment can be expanded and contracted toward a gravity direction GV through the restraint of the rear bracket 120 and the linkage member 300. In turn, the length of the retractable heel 200 is changed, so that it can meet the needs of the user and solve the problem that the user must have high heels with different heel heights at the same time.

For example, the retractable heel 200 includes a telescoping link 210 and a telescoping support 220. The telescopic link frame 210 is retractable, and the telescopic link frame 210 is pivotally connected to one side of the rear bracket 120 with respect to the front bracket 110. The extension of the telescopic link frame 210 is changed by the extension of the rear bracket 120 and the linkage 300.

The telescopic support member 220 is expandable, and the telescopic support member 220 is fixed to the telescopic link frame 210. Therefore, the telescopic support member 220 can be changed in accordance with the length of the telescopic link frame 210, and synchronously expand and contract in the same direction and in the same proportion.

More specifically, the rear bracket 120 pivotally connects the front bracket 110 through at least one first pivot R1 and pivotally connects the telescopic link frame 210 through a plurality of (for example, two) second pivots R2, so that the rear bracket 120 can be A pivot R1 pivots relative to the front bracket 110, and the telescopic link frame 210 is pivotable relative to the rear bracket 120 in accordance with the second pivot R2. The linking member 300 pivotally connects the protruding rib 111 through the at least one third pivot R3, and pivotally supports the telescopic support member 220 through the at least one fourth pivot R4, so that the linking member 300 is relatively convex according to the third pivot R3. The rib 111 is pivoted, and the telescopic support 220 is pivoted relative to the linkage 300 in accordance with the fourth pivot R4. It should be understood that the axial directions of the first pivot R1, the second pivot R2, the third pivot R3, and the fourth pivot R4 are parallel to each other, but are not coaxial with each other.

Fig. 2A is a perspective view showing the shoe 11 of the adjustable heel height according to the embodiment of the present invention. Fig. 2B is an exploded view of the shoe 11 of Fig. 2A. In addition to the above-described shoe board 100, the retractable heel 200 and the linkage member 300, the shoe 11 of the present embodiment further includes a shoe body 400, a sole layer 500 and at least one locking mechanism 600. The body 400 is, for example, a material that completely or partially covers the foot. It is to be understood that the body of the shoe generally refers to the type of appearance of all the shoes, and the present invention is not limited to the one shown in the drawings. The shoe panel 100 is located between the shoe body 400 and the sole layer 500 and connects the shoe body 400 and the sole layer 500, respectively. The sole layer 500 has a through opening 510, the through port 510 is aligned with the rear bracket 120, and the retractable heel 200 extends out of the sole layer 500 via the through opening 510. The locking mechanism 600 is coupled to the shoe panel 100 for removably securing the retractable heel 200 to prevent the telescoping movement of the retractable heel 200, thereby determining the length of the retractable heel 200. In addition, in the present embodiment, the sole layer 500 further encloses the locking mechanism 600, the linking member 300 and a portion of the shoe panel 100 therein. However, the invention is not limited thereto.

Specifically, the shoe panel 100 has an opposite configuration of the upper side 101 and the lower side 102. The shoe body 400 is located on the upper side 101 of the shoe panel 100, and the retractable heel 200, the linkage member 300 and the sole layer 500 are all located on the underside 102 of the shoe panel 100. In addition, the bracket 120 is further provided with a slot 121 after the shoe board 100. The slot 121 exposes a portion of the sole layer 500 and the through opening 510. The linking member 300 further has a breaking opening 301.

FIG. 3 is a schematic view showing the operation of the shoe 11 of FIG. 2A. 4 is a schematic view of the retractable heel 200 of FIG. 2A. As shown in FIGS. 3 and 4, in the present embodiment, the telescopic support 220 includes a plurality of sleeves 221. The sleeves 221 are concentrically arranged with each other and are telescopically sleeved together in the longitudinal direction LA of the telescopic support 220. In detail, each sleeve 221 passes through a through space 222, that is, each sleeve 221 surrounds the through space 222. In any two adjacent sleeves 221, one of the sleeves 221 is located in the through space 222 of the other sleeve 221. In the order from the outside to the inside, the dimensions of the sleeves 221 are gradually large to small. Thus, by stretching the sleeves 221, the length of the telescopic support 220 is changed. However, the present invention is not limited thereto, as long as the sleeves can be sequentially sleeved, the sleeves are not limited in shape. Must be consistent.

In addition, as long as the retractable link frame can sequentially fix several or all of the sleeves, the retractable link frame does not have to be embedded in the telescopic support member. In other embodiments, the retractable link frame can also be Parallel to the telescopic support (not shown).

Further, the telescopic link frame 210 includes a plurality of first links 211 and a plurality of second links 212. The adjacent first link 211 and the second link 212 are pivotally connected to each other through a first shaft pin 213. The first links 211 and the second links 212 are connected to each other through the second shaft pins 214 in a head-to-tail manner. These first links 211 are parallel to each other, however, these first links 211 are not limited to the same length or the same type. These second links 212 are parallel to each other, however, these second links 212 are not limited to the same length or the same type, and the first link 211 and the second link 212 are not limited to the same length or the same type.

Thus, when the first link 211 and the second link 212 pivot relative to each other such that the distance between the first shaft pins 213 changes (reduced or enlarged), the telescopic link frame 210 changes correspondingly ( Reduce or enlarge) its length.

It should be understood that since the retractable link frame 210 is located in the through space 222 of the innermost sleeve 221, and through several or all of the first shaft pins 213, respectively, along the long axis direction LA of the retractable link frame 210 A plurality or all of the sleeves 221 are attached. In this manner, the telescopic support member 220 can be flexibly expanded in the same direction and in the same proportion as the length of the telescopic link frame 210 changes.

In practice, in order to give way to the first pin of these fixing sleeves 221 213, in order to fold the sleeves 221 together, except for the sleeve 221 connecting the linkages 300, the remaining sleeves 221 respectively have a positional slit 223, and the sleeves 221 are in the order from the outside to the inside, The length of the bit gap 223 of these sleeves 221 is gradually reduced from small to large.

As shown in Figures 3 and 4, since one of the first links (e.g., the first link 211A closest to the body 400) is simultaneously transmitted through two axle pins (e.g., the first axle pin 213A and the second axle pin) 214A) symmetrically pivoting the rear bracket 120, so that when the rear bracket 120 is reversed relative to the front bracket 110 to drive the telescopic link frame 210 to expand and contract in the direction of gravity, since the rear bracket 120 only drives the first link 211A to pivot, The second link 212A can only be interlocked with the first link 211A, and the first link 211A and the second link 212A are not rotated at the same angle at the same time. Therefore, the length of the extendable link frame 210A corresponds to the long axis direction LA. At the same time as the ground changes, the telescopic link frame 210 and the telescopic support member 220 are more likely to produce lateral displacement. (Refer to Figure 1A and Figure 1B).

In other words, when the first link 211A of the telescopic link frame 210 is prevented from rotating, the telescopic link frame 210 and the telescopic support member 220 can be prevented from being telescoped in the direction of gravity, thereby fixing the telescopic link frame. The exposed length of the 210 and the telescopic support 220 (ie, the retractable heel 200).

In order to limit the position and prevent the first link 211A of the telescopic link frame 210 from rotating, in the present embodiment, the outermost sleeve 221 is provided with a plurality of fixing holes 224, and the fixing holes 224 are arranged according to an arc shape. The manner of arrangement is to match the trajectory curvature of the displacement of the retractable link frame 210.

Because the fixing holes 224 respectively correspond to a plurality of lengths determined by the telescopic support 220, for example, the telescopic support 220 has four solids. The fixed aperture 224, when extending into each of the fixed apertures 224 to limit displacement of the telescoping linkage 210, exhibits four different exposed lengths.

FIG. 5 is a schematic view showing the locking mechanism 600 of FIG. 2A. FIG. 6 is a schematic view showing the operation of the locking mechanism 600 of the shoe 11 of the adjustable heel height according to the embodiment. As shown in FIGS. 5 and 6, in the present embodiment, the two latching mechanisms 600 are located on opposite sides of the shoe panel 100. Each locking mechanism 600 includes a body 610, a spring 630 and an operating portion 640. The frame 610 has a first end 611, a second end 613 and a pivoting portion 612. The pivoting portion 612 is interposed between the first end 611 and the second end 613. The pivoting portion 612 and the rear bracket 120 are pivoted to each other, so that the frame body 610 can be rotated according to the pivoting portion 612. One face 611a of the first end 611 of the frame 610 has a fixing pin 620. The fixing pin 620 is inserted into one of the fixing holes 224 in a pluggable manner. The spring 630 is coupled to a stationary member (such as the sole layer 500) and the other surface 611b of the first end 611 of the frame 610 for pushing the fixing pin 620 back into the fixing hole 224. One end of the operating portion 640 abuts against the second end 613 of the frame body 610, and the other end of the operating portion 640 is exposed outside the shoe 11. Therefore, when the spring 630 continues to protrude into the fixing hole 224 against the fixing pin 620, the fixing pin 620 limits the movement of the sleeve 221, and also limits the length of the telescopic link frame. On the other hand, as shown in FIG. 6 , when the user simultaneously presses the operating portion 640 of each locking mechanism 600 to push the second end 613 of the frame body 610 , each operating portion 640 rotates the frame body 610 to drive the fixing pin 620 out of the sleeve. A fixing hole 224 of the cylinder 221 .

However, the present invention is not limited thereto. Except that the locking mechanism 600 is the frame body 610, the spring 630 and the operating portion 640, the present invention is not limited as long as the telescopic support member 220 can be limited to determine the length of the telescopic support member 220. The specific form of the locking mechanism. For example, the locking mechanism includes a fixing pin (not shown) Show). The fixing pin is a separate object, and the fixing pin is insertably inserted into one of the fixing holes to restrict the movement of the sleeve.

7A to 7C are schematic views showing the continuous operation of the shoe 11 which can adjust the height of the heel according to the embodiment. As shown in FIG. 7A, the shoe body 400 and the shoe panel 100 define a space together. This space is used to accommodate a single foot 700 of the human body. When the human foot 700 is inserted into the shoe of the present embodiment, the user's foot 700 is substantially located on the shoe board 100, the front bracket 110 carries the toe portion 710 of the human foot 700, and the rear bracket 120 carries the human foot 700. Heel portion 720.

Therefore, when the height of the heel is to be extended, the user first presses the operating portion 640 of the locking mechanism 600 to release the fixing pin 620 from the fixing hole 224, and the expansion and contraction of the telescopic support member 220 is released (refer to FIG. 6); Next, as shown in FIG. 7B, the user raises the heel portion 720 to bend the toe portion 710 to a certain extent to reduce the angle θ between the rear bracket 120 and the front bracket 110, at this time, due to the retractable heel 200 The elongation begins so that the fixing pin 620 exiting the fixing hole 224 starts to slide relatively on the surface of the sleeve 221; the additional pin 620 is slid into the other fixing hole 224 to determine the other exposed length of the retractable heel 200. Similarly, as shown in FIG. 7C or FIG. 3, when a larger heel height is required, the user can continue to reduce the angle θ between the rear bracket 120 and the front bracket 110, so that the retractable heel 200 can be extended again. length.

In this way, the present embodiment can control the exposed length of the retractable support member by the bending width of the bent shoe board to meet the user's use requirements, thereby solving the problem that the user must have different heel heights at the same time.

It should be understood that the above-mentioned retractable heel, linkage, and front branch The number of the frame, the rear bracket, the first to fourth pivots, and the locking mechanism are merely examples, and are not intended to limit the present invention. Those having ordinary knowledge in the technical field of the present invention should flexibly adjust the above according to actual needs. Quantity.
