Description

Paper-plastic shoe support

[Technical Field]

The invention relates to a paper-plastic shoe brace, in particular to a paper-plastic shoe brace that can be quickly adjusted according to the needs of the supported shoe shape to achieve the true support of the shoe shape.

【Background technique】

Buying shoes is a very happy thing. Buying good-looking shoes is good for walking, improving health, and social. It can be seen that the fit and good-looking of shoes is an important thing. There are many sizes of shoes in manufacturing. For example, sizes 22 to 28 are common. Sizes lower than 22 and higher than 28 are often rare. It is more difficult to purchase directly on the market, and it may often need to be customized. The shoes are made from the shoe factory, and then the surface is brightened and the whole shoe is packaged, shipped to the middle plate, and then shipped to the terminal retail market (for example: shoe store) for display display, until it is selected for the shoe-rewarding consumer. Wear, try on, try on again, and then make sure to pay for the purchase and take it away. In the whole process, you must maintain the fullness and beauty of the shoes. Therefore, the shoe factory will insert the shoes inside after the production is completed. An object of a "shoe stay". The shoe stay can support the shoe upper to avoid affecting the fullness and aesthetic appearance of the shoe due to the deformation of the shoe upper (referring to the relatively unplugged shoe stay).

Based on cost considerations, early shoe factories adopted the use of plugs to support the shoe body. It is undeniable that plugging the paper ball inside the shoe body is of course also a function of shoe support. However, plugging the paper ball to fix it The effect is not good, and it is more difficult to match the shoe upper. Therefore, the amount of paper ball or its shape must be continuously adjusted manually to achieve the effect of supporting the shoe upper and avoiding the deformation of the shoe upper. The practice of shoe body is outdated, unless it is a last resort, shoe factories have not adopted it.

Later, an integrated shoe support made of plastic material injection molding technology came out, which can achieve full support and reuse, except for the sale of plastic shoe support products that are still on the market, such as an adjustable advance and retreat length. Link-type plastic shoe support, but its manufacturing cost is relatively high and the components are complex. It is only suitable for individual shoe appreciation consumers to purchase a single piece for home maintenance and love shoes. It is not suitable for large-scale use in shoe factories. If the production technology of the shoe support is poor, sometimes it will easily cause damage to the shoe body, so it must be used very carefully. Shoe braces made of plastic materials have also been used by shoe factories for some time. Later research found that plastic products made of plastic materials can easily release toxins and cause serious pollution to the environment. It is difficult to recycle them after destruction, or Recycling and disassembling is difficult to handle, and the cost of recycling is huge, so industrial plastics are also criticized.

In response to the trend of environmental protection and the reduction of the use of plastics, and under the driving force of finding new materials, there have been developments in which pulp fiber materials and / or plant fiber materials are mixed and beaten as pulp materials. Slippers, which are manufactured by hot pressing technology, come out. Due to the differences in manufacturing materials and manufacturing methods, they are generally referred to as "" paper-plastic shoe braces "to distinguish them from" plastic shoe braces. " With the rising awareness of environmental protection nowadays, the reduction of the use of plastic materials has become an important R & D issue and progress trend of various brand shoe factories. As far as is known, there are two types of conventional paper-plastic shoe braces:

The first conventional paper-plastic shoe support is manufactured according to the volume of the plugged shoe body. Therefore, the manufactured paper-plastic shoe support is full in appearance. After being inserted into the shoe body, the correct appearance and shape of the shoe body can be completely supported. Open and make the shoe body on display exhibit its due aesthetics. However, when the terminal retail market (for example: shoe store) is on sale, the shoe-rewarding consumer takes out the paper-plastic shoe brace and tries on the shoe body. When the paper-plastic shoe support is repeatedly plugged back into the shoe body, it is easy to cause the paper-plastic shoe support to be damaged and deformed, and it is difficult to repeatedly plug it back completely, that is, the first known paper-plastic shoe support is manufactured to fit the volume of the shoe body to make it look complete. And it is full, which leads to easy damage and deformation on repeated use, and the lack of a long service life. Furthermore, because each size of the shoe body must be equipped with paper and plastic shoe braces that can be matched with the plug, various types of shoes Paper-to-plastic shoe supports cannot be mixed, so paper-to-plastic shoe supports must be prepared for diversification (with different shoe models) and multi-types (with different shoe types), which is also lacking in its use.

The second conventional paper-plastic shoe brace is a one-stage design. The main part is to make the part corresponding to the toe full, and the heel part is reduced and straightened. Therefore, consumers of shoe appreciation use the second conventional paper-plastic shoe brace. When taken out from the heel part, because the heel part is reduced, it is easy to take out, but because the second known paper-plastic shoe stay is not designed according to various shoe types, so whether it is assembled in the shoe factory, Or when a shoe-watching consumer repeatedly inserts it, it is easy to cause the edge surface of the middle part of the shoe body to be pressed due to interference, resulting in the lack of warping and deformation of the shoe body.

It can be seen at this point that the current shoe manufacturers have mostly used paper-plastic shoe braces to support the shoe body. The paper-plastic shoe braces have the advantage of being difficult to hurt the shoe body due to their relatively low hardness. However, due to the numerous shoe styles and The shoe size is different, which results in a huge cost burden on the mold for producing paper-plastic shoe braces, which cannot meet the needs of economic benefits, and the real value is improved.

12, 25.

The paper-plastic shoe stay 1 manufactured according to the above structural composition is used to hold the rear part 30 of the paper-plastic shoe stay 1 by hand, and the front support surface 11 of the front part 10 is plugged toward the opening of a shoe (such as a leather shoe). Then, the rear peripheral surface 31 of the middle section 20 and the rear section 30 are also filled into the opening of the shoe (such as leather shoes). Therefore, the front support surface 11 and the support arc surface 13 are full. The outer shape of the model and the corresponding application of the rear peripheral surface 31 to the inner curved surface of the rear shoe body can provide the most appropriate support for the shoe body of the shoe (such as leather shoes).

During the action of completely inserting the paper-plastic shoe support 1 into the shoe body of the shoe (for example, leather shoes), there will inevitably be obstacles. At this time, only a little force is needed to push the rear section 30 to make the middle section 20 makes a slight deformation in length, or slightly twists the rear section 30 to make the middle section 20 slightly deform the angle, so that the overall paper-plastic shoe support 1 can be smoothly guided into the shoe body of the shoe (such as leather shoes). To provide the most appropriate support for the shoe body.

The above means that the paper-plastic shoe support 1 has a good corresponding relationship with the shoe body, so the paper-plastic shoe support 1 can smoothly enter the shoe body to provide support. However, in the actual shoe-making process, it may not be possible that all the finished shoes have a shoe body that matches the shoe size. Sometimes there is a slight error in the total length, sometimes there is a slight error in the left and right angles between front and back, and sometimes there is a front and rear. The slight error between the up and down angles is very common. Therefore, when the paper-plastic shoe stay 1 is actually used to insert into the shoe body, if it is found that the correspondence of the shoe body to be inserted is not so consistent, then the middle part of the paper-plastic shoe stay 1 of the present invention 20 can be operated to perform stretching, pushing, rotating, twisting, pulling and other actions to make corresponding adjustments according to different shoe shapes, and finally achieve the smooth insertion of the adjusted paper-plastic shoe stay 1 into the shoe body, In order to support the function of the shoe body.

Please refer to FIG. 8, when the shoe body to be supported is obviously slightly shorter, as shown in the small diagram in FIG. 8 (a), one hand stabilizes the front part 10 of the paper-plastic shoe stay 1, and Grasp the rear section 30 of the paper-plastic shoe support 1 with one hand, and then push the rear section 30 with a little force, so that the deformable surface 21 of the middle section 20 can be retracted by linkage, as shown in FIG. 8 As shown in the small picture in (b), in this way, the overall length is slightly shortened, and it can be smoothly inserted into a slightly shorter shoe body. When the rear part 30 is pushed, its force is transmitted to the deformable surface 21 via the connecting section 23, because in the structure of the overall paper-plastic shoe support 1, the deformable surface 21 is just designed to be most easily stressed The deformed part, coupled with the symmetrically arranged squeezing line grooves 22 on the deformable surface 21, further exacerbates the ease of deformation. Therefore, as soon as the driving force comes, the deformable surface 21 shrinks inward. To shorten the total length.

It must be mentioned that due to the material, although the paper-plastic shoe support 1 is not immediately broken or chipped when it is pushed by force, it can be deformed, and after the reaction force is applied, its deformation can be fully or partially restored. . Therefore, under the same conditions, if the shoe body to be supported is obviously slightly longer, as long as one hand holds the front part 10 of the paper-plastic shoe stay 1 and the other hand grasps the rear of the paper-plastic shoe stay 1 Segment 30, and then pull the rear segment 30 with a little force, then the deformable surface 21 of the middle segment 20 can be extrapolated through the linkage. In this way, the overall length is slightly elongated, and the plug can be smoothly plugged. When placed in a slightly longer shoe body, it also achieves good support.

Next, please refer to FIG. 9. When the rear part of the shoe body to be supported is obviously slightly shifted to the right, as shown in the small diagram in FIG. 9 (a), hold the paper-plastic shoe support with one hand. 1 of the front section 10, the other hand grasped the rear section 30 of the paper-plastic shoe support 1, and then slightly twist the rear section 30 with a force to shift to the right, so that the middle section 20 The deformable surface 21 has the phenomenon of one side retracting and one side pushing out. Therefore, the overall paper-plastic shoe support 1 can make a corresponding angular offset (distortion) to smoothly insert shoes with a slight right-off angle In vivo, a good corresponding supporting effect is also achieved.

When the rear part of the shoe body to be supported is obviously slightly shifted to the left, as shown in the small picture in FIG. 9 (b), one hand is used to hold the front part 10 of the paper-plastic shoe support 1 and the other hand is grasped. Hold the rear section 30 of the paper-plastic shoe support 1, and then twist the rear section 30 with a slight force to shift it to the left, so that the deformable surface 21 of the middle section 20 is extrapolated on one side through interlocking. The phenomenon of inward contraction on one side, so the overall paper-plastic shoe support 1 can make a corresponding angular offset (distortion), so that it can be smoothly inserted into the shoe body with a slight leftward deviation angle, and also achieve a good corresponding support effect.

Next, as shown in FIG. 10, when the rear part of the shoe body to be supported is obviously slightly shifted upward, as shown in the small diagram in (a) of FIG. 10, the paper-plastic shoe stay 1 is stabilized with one hand. The front section 10 of the first section, hold the rear section 30 of the paper-plastic shoe support 1 with the other hand, and then apply a slight force to move the rear section 30 upward, so that the middle section 20 can be moved through the linkage. The deformed surface 21 is correspondingly deformed, as shown in the small diagram in FIG. 10 (b). In this way, the rear part 30 of the paper-plastic shoe support 1 will be slightly shifted upwards to smoothly insert the rear part slightly. Offset shoe body. By the same token, when the rear section of the shoe body to be supported is obviously slightly shifted downward, hold the front part 10 of the paper-plastic shoe support 1 with one hand, and grasp the rear part of the paper-plastic shoe support 1 with the other hand. Segment 30, and then apply a slight force to move the rear segment 30 downward, so that the corresponding deformation of the deformable surface 21 of the middle segment 20 is caused by the linkage, so that the rear part of the paper-plastic shoe support 1 The part 30 makes a slight downward movement to smoothly insert into the shoe body with a slight downward displacement in the rear section.

From the above description, it can be known that the middle section 20 in the present invention is the soul section of the overall paper-plastic shoe stay 1, and the middle section 20 cooperates with the waist section (middle section) of the shoe shape of the shoe body to make two sides retracted and become a section independently. In particular, the front end of the middle section 20 is connected to the front section 10 by the deformable surface 21, and the rear end is connected to the rear section 30 by the connecting section 23, and most of the deformable surface 21 is symmetrical. The squeezed line grooves 22 are arranged, so when holding the front section 10 and the rear section 30 with their hands, they can perform stretching, pushing, rotating, twisting, and pulling in the second-hand room. When the force reaches the deformable surface 21 via the connecting section 23, the deformable surface 21 is deformed correspondingly, so that the overall paper-plastic shoe support 1 immediately responds to the shape of the shoe body, so that it can be smoothly filled. Into the body of the shoe to be supported, the most appropriate support can be provided to the shoe body, that is, the front end (toe) and rear end (heel) of the shoe body are applied with appropriate support forces to maintain the shoe body. Fullness.

It must be mentioned that the supporting arc surface 13 on the bottom and two sides of the front section 10 has the function of guiding the front section 10 to smoothly slide into the toe; the connecting section 23 of the middle section 20 is connected to the front and rear sections. In addition to the role of the main, the force applied by the operator is completely transmitted to the deformable surface 21, so that the deformable surface 21 is immediately correspondingly deformed; the hand-access hole 34 in the rear part 30 is provided for When the paper-plastic shoe stay 1 is taken off the shoe body, a finger can easily reach into the place where the force is applied.
