Indoor slippers for outside footwear and removable insole slippers with/without removable upper part
The three invention's utility designs can be used for all types of footwear, including slippers and sandals for indoors, outdoors, SPA, hotel slippers and etc. The first core invention are removable and washable insoles/socks that are pulled over/attached to the base/hard insole of slippers with options when upper parts are also detachable. The second invention is the closed-toes slippers with ventilation holes both on the cloth insole and upper part with option to have it combined with the first invention. The third invention's distinction is the giant size of slippers that are worn over the outdoor footwear that can also have options with the removable sock or ventilation holes from inventions mentioned earlier. There are different details variations described in specifications for all three interrelated inventions. These slippers provide more hygiene, can be worn longer, which is more economical for households and reduces waste produced by slippers.
The utility models relate to the technical field of slippers, and particularly relates to the slippers with removable/replaceable insoles where also upper parts can be removable. Also, second related to the first invention includes slippers that provide better ventilation along with providing replaceable insoles. Also, third type of the invention is related to the cover/slippers for outdoor footwear. All three types of invented slippers can have an option with removable insole.
BACKGROUNDA slipper is a piece of footwear consisting of an upper part covering the instep and a base sole on which the foot is placed. Existing slippers typically have a single integrated insole that is permanently attached to the lower part of the slipper. Latest inventions include slippers where upper part is removable, insole is removable or some of the layers are removable (TWM623606U, U.S. Pat. Nos. 6,931,766B2, 1,286,446, JP2017104459A). Slippers are may be made of materials such as rubber, foam, leather or any other materials to provide varying levels of support and comfort. Currently slippers of different materials have were removable insoles that are also made from rubber, foam or similar materials. However, such slippers do not typically include in the pack customization or replacement of the insoles, which can be an issue for users who may want to replace the insoles due to wear, dirt and tear. There are inventions with closed-toes slippers where socks like insoles are removable and washable (U.S. Pat. Nos. 1,286,446, 1,066,596, CN202566498U). However, there are no such for open-toes slippers or for closed-toes slippers with ventilation holes. There is also invention where the cotton like material is pulled over to the outer side of the base of the slipper to wipe floors (KR20220000397U). However, such invention has reverse side of the “cloth” placement and has different purpose for the invention. Particularly, the purpose is to keep the floors clean with no focus on feet. One of the utility models on this patent includes slippers that aim to keep the floors clean by allowing them to be worn with shoes on. Slippers are often worn indoors barefoot, so they become dirty and wet inside easily. So, the inventions like machine washable slippers, closed-toes removable insole sleepers, breathable, moisture absorbing slippers were invented. However, they are still not fast to dry and requires time before wearing slippers again. The rubber, plastic and EVA slippers are worn and water resistant, easy to wash and dry, but less comfy to feet in terms of texture, sweat stimulation and smell. Cloth and leather slippers are more comfortable but lack of wear resistance and long to dry and easy to damage. Also, hotels and SPA use disposable slippers that are used only once and not comfortable to feet. So, combination of the removable and hygiene cloth with EVA/plastic and rubbers (or similar quality materials) base soles contains benefits of both types of slippers and also be used in hotels and SPAs. Moreover, if rubber, plastic and EVA part of the slippers and disposable slippers will be thrown away less frequently, it will result in less waste and pollution. Therefore, there is a need for slippers with removable insoles that can be easily replaced and customized to meet the needs of the user and to reduce pollution. Also, there is a need of the slippers that can be worn with shoes on, so people can wear them without taking off the outdoor footwear.
BRIEF SUMMARY OF THE INVENTIONThe invention addresses the limitations of traditional slippers that have a single integrated sole and do not allow for customization or replacement of the insole/socks in open-toes and closed-toes with holes slippers and/or with removable and replaceable upper part and/or when upper part sock is attached to the upper part and is also removable and replaceable. With the present invention, users can easily replace the sock/insole as needed to provide more clean and fresh experience of wearing slippers. Moreover, socks can be of different colors and design, which makes slippers customizable according to users taste and preferences in that matter.
Depending on the design of the slippers the socks could also be specially designed or stitched to fit snugly over the removable insole or base of the slippers, providing maximum comfort and support. Also, the base part of traditional slippers is usually thrown away due to the wear of other parts, so the current invention allows to reduce waste produced by slippers, by making easily damaging parts removable and replaceable.
The inventions variation where the detachable and washable slippers where outer sole and upper part could be removed simultaneously and separately from each other and from the base part is particularly useful for hotels and SPA industry. Considering amounts of existing disposable slippers just in hotel industry, the amount of waste could be significantly reduced while benefiting on costs spend on slippers.
Removable and replaceable cloth part that are can be washed and dried faster, while replacing cloths/socks of insole and of upper part provide hygiene and more comfort to hide and SPA guests. Base parts and overall slippers can be made from different materials like rubber, EVA, TPU and etc. Same is for cloth part that can be made from variety of cottons and other materials compositions.
The slippers model that is design to be worn over the outdoor footwear, can also have removable and replaceable sock insole to make the slippers long lasting.
Compared with the prior art, the beneficial effects of the utility models are that: Sock/insole and cloth part of the upper part or replaceable upper part can be easily removed and replaced and washed, which reduces waste produced by slippers in households and hotels and SPA industry. Slippers for outdoor footwear benefit people who don't want to remove the outdoor footwear and walk inside home.
The advantages and features of novelty characterizing the present invention are pointed out with particularity in the appended claims. To gain an improved understanding of the advantages and features of novelty reference may be made to the following descriptive matter and accompanying drawings that describe and illustrate various embodiments and concepts related to the invention.
There are 16 figures in total that has designated numeration of the slipper's parts: 1—base part of the slipper, 2—removable internal hard insole or slots on base for sock insole, 3—replaceable sock insole, 4—upper part that could be or not removable and replaceable, 5—means of attachment of upper part with base or means of attachment cloth that covers the upper part, 6—attachment means of the sock insole or mean of attachment on base/hard insole, so sock insole holds better to the base part or to the hard insole part, 7—slots/holes in sock insole 8—a removable cloth to cover the upper part, 9—gaps/holes on upper part for better ventilation. According to numbers are used in all figures, despite presence of all parts on a figure, 10—assembled slipper with all parts.

DETAILED DESCRIPTION OF THE INVENTIONFor the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
There are three main utility designs of slippers covered in this patent that are interrelated through the variations of them. Even though the patent application describes the utility models in slippers, the models can be applied to sandals and different types of footwear. The main idea of the first invention is to make slippers that have removable and replaceable insole in different variations. The second main utility invention is the closed-toes slippers with ventilation holes that can have removable insoles like in the first utility design invention. The third utility design of the invented slippers is all variations of the first two utility designs and regular slippers but in extra-large size and more tall upper part that can fit the feet with outdoor footwear on them, so user can walk in them inside the house without making the floor dirty but still wearing the outdoor footwear.
All utility design inventions are covered by 26 claims out of which 8 are independent. The utility designs and its variations schematically presented on the drawings, but not limited to the drawings.
Same invention as per claim 1 where sock insole is pulled over the hard insole, that then is placed into the base are showed on
Claim 4 is dependent claim of the claim 1, where one means of attachment by glue/stitching of removable insole sock to the removable hard insole is emphasized, because it looks like one whole piece/part and may have offered second replacement piece of it in the same box or store. Schematic drawings are presented in
Claim 8 with schematic
Claim 9 is also like a derivative from claim 8, but it has design of the base with insert spaces/slots/attachment means or without them that allows the sock insole to be attached/pulled over to the base directly into those inserts/slots/attachments or to the base. Such design of the base keeps the sock insole away from touching the floor and removes necessity of the separate removal hard insole to make sock insole attachable and removable, which eases the production process and may reduce materials used.
The closed-toes slippers with functionality of having the sock insole pulled on/attached to the base part is mentioned in a separate independent claim 18. Such slippers can also have ventilation holes to make the slippers more comfortable to wear. As previous models these slippers can also have wide variety of designs and additional removable parts as cloth for upper part, attachment means, designs, upper parts itself which can be removable or not removable and etc.
Independent claim 19 is also related to the closed-toe slippers, where the main utility design idea of having removable insole (internal cloth/sock) is preserved. However, this claim covers the removable insole that is stitched together with the upper part, where it has ventilation holes similar to the ones on upper part that is one piece with the base part.
Main idea of claim 20 is to produce slippers of giant/large size that can be worn with the outdoor footwear on. Such slippers will keep the floors clean while allowing people to walk indoors with their outdoor shoes on. Such giant slippers can be of different shapes and designs as long as there are big sizes that fit the feet with outdoor footwear on, that's why the
