Description

[Technical field]

[0001] To provide slippers which have a function of easily attaching and detaching a commercially available indoor cleaning sheet and can be used without impairing the appearance of slippers for everyday use even when the sheet is attached. [Background technology]

[0002] An invention has been made for slippers that have an added function for replacing indoor cleaning sheets, allowing users to clean while wearing them on a daily basis.

[0003] For example, there are slippers in which the male side of adhesive tape or Velcro (registered trademark) is attached to the bottom of the slippers and a cleaning sheet is then pressed onto it (see Patent Documents 1 and 2), slippers in which a cleaning sheet is attached to a bottom sole material that is attached and detached to the bottom of the slippers with an adhesive member (see Patent Document 3), slippers in which a cleaning sheet is attached directly to the bottom of the slippers using an adhesive substance (see Patent Document 4), and slippers in which the bottom sole of the slippers is partially expanded and a locking member for the cleaning sheet is provided thereon (see Patent Documents 5 and 6). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2009-213839 A [Patent Document 2] Utility Model No. 3113478 [Patent Document 3] JP 2006-191995 A [Patent Document 4] JP 2009-22703 A [Patent Document 5] Utility Model No. 3113168 [Patent Document 6] JP 2005-144111 A Summary of the Invention [Problem to be solved by the invention]

[0005] When considering existing inventions from the perspective of whether they are suitable for everyday use in terms of appearance and function, do not require special maintenance, and can be easily replaced with inexpensive commercially available cleaning sheets, none of them currently meet some of the criteria.

[0006] To summarize specifically, conventional slippers with cleaning functions had the following problems: (a) The cleaning sheet protrudes from the slipper body, so while this is not a problem if the slipper is used only for cleaning, its appearance makes it difficult to use it on a daily basis. (Patent Documents 5 and 6) (b) Due to the structure, it is necessary to prepare a cleaning sheet with the same shape as the slipper body, and inexpensive, commercially available indoor cleaning sheets cannot be used without modification. (Patent Documents 1, 2, 4) (c) Dirt and hair can get tangled in the male part of the Velcro (registered trademark) that fastens the cleaning sheet, and the male part is made of a hard material and is exposed when it comes into contact with the floor, which can damage the floor. (Patent Documents 1 and 2) (iv) When removing the cleaning sheet, the male side of the Velcro (registered trademark) has a strong grip, so the cleaning sheet cannot be removed easily, requiring a certain amount of force from the user and causing stress. (Patent Documents 1 and 2) (E) The structure is such that the cleaning sheet can be attached and detached using a removable board bottom material or an adhesive substance, but in slippers on which the user's entire weight is placed, the retention strength of the structure and material shown is such that they are likely to come off easily, making it difficult to fulfill both daily use and cleaning functions. (Patent Documents 3 and 4)

[0007] Based on the above, the present invention has devised a slipper that looks almost the same as an ordinary slipper and can be used daily without difficulty, does not require any extra maintenance such as removing dirt that adheres to the slipper body, can use inexpensive commercially available cleaning sheets as they are without any processing, and maintains the cleaning sheet in a state that is difficult to remove even when fully performing the floor cleaning function, and yet has a structure and function condensed into one that allows the cleaning sheet to be easily attached and removed without stress. [Means for solving the problem]

[0008] The slippers have the appearance of a double bottom sole, with a board bottom sole of the same shape overlaid on the bottom sole of the slipper body, and a cleaning sheet is wrapped tightly along the shape of the additional board bottom sole, and the tip part protruding from the bottom sole shape is pushed and held between the double bottom soles, thereby maintaining a neat appearance and providing a natural feeling for everyday use.

[0009] A thin and flexible sheet-like fastener connects the double bottom soles and, through its unique action, enables easy attachment and detachment of the cleaning sheet and provides stable holding power. For each pair of slippers, about 4 to 6 sheets of this fastener are arranged vertically and horizontally between the double bottom soles, with the sheet-like fasteners fixed alternately to the upper and lower bottom so that they cross.

[0010] Due to the structure of this crossed sheet-like fastening device, the double bottom base itself is firmly connected, but it is possible to open one side wide, which not only makes it easier to push in the tip of the cleaning sheet with your fingers, but also allows you to touch the tip of the cleaning sheet from the other side, making it possible to pinch and pull to adjust the slack.This not only increases the holding power of the cleaning sheet, making it less likely to come off, but also allows the cleaning sheet to fit beautifully and cover the shape of the bottom base of the board body.

[0011] Furthermore, since this structure only clamps the cleaning sheet and does not hook or secure it in any way, the cleaning sheet can be removed stress-free by simply opening a part of the double bottom and pinching and gently pulling one end of the cleaning sheet.

[0012] As described above, the double bottom sole equipped with the sheet-like fixing device is highly effective in attaching and removing the cleaning sheet pushed in from the side and in stably holding it in place; however, due to the characteristics of the structure, the clamping force at both ends of the slippers is weak and gaps are likely to form in the double bottom sole. Therefore, by equipping both ends with ferromagnetic material, the adhesion between the bottom soles is reinforced by magnetic force, but by maintaining a structure that clamps the cleaning sheet rather than hooking it, it is possible to achieve both easy and stress-free attachment and removal and more stable holding force.

[0013] As described above, the double undersole is the key to making this slipper suitable for both cleaning and everyday use, and this double undersole structure can be incorporated into any slipper with a undersole. As such, just like regular slippers, it is possible to meet a variety of design, size, cost performance, and other requirements, and it has the potential to become widely popular. Effect of the Invention

[0014] According to the present invention, a commonly available indoor cleaning sheet can be easily attached to and detached from the slipper body without any stress.

[0015] When installing, although the bottom of the board body is fixed to the bottom of the slipper body, it has a unique structure that opens wide laterally on one side, leaving ample space to insert fingers holding the edge of the cleaning sheet, making it easy to push in.In addition, the slack can be adjusted by pinching the sheet on the other side through the gaps in the sheet-shaped fixing device or the spaces carved out of the parts, making it possible to ensure that the cleaning sheet fits perfectly against the bottom of the board body.

[0016] The product of the present invention has the same neat appearance as a pair of slippers even when using a cleaning sheet, so it can be worn daily as an ordinary pair of slippers without any discomfort, and can pick up dirt, dust, hair and pet hair by simply sliding the slippers over any area the user has walked on or any area of ​​concern.

[0017] Furthermore, it is possible to efficiently clean floors by using a vacuum cleaner while wearing the product of the present invention, without using a cleaning tool with a replaceable cleaning sheet with a handle.

[0018] Furthermore, the cleaning sheet can be easily removed by gently opening the double bottom and pinching and pulling a part of the edge of the sheet.

[0019] Since the cleaning sheet is simply held in place by pressure without any snags, not only can the cleaning sheet be removed without applying force or stress, but the cleaning sheet can also be disposed of without getting your hands dirty, so this is likely to be well received by users who change cleaning sheets frequently, especially those who keep indoor pets.

[0020] In addition, since the cleaning sheet covers the soles of the slippers, it also helps prevent the slippers themselves from getting dirty, helping to extend their lifespan.

[0021] From the outside, the slippers have a thick double sole, and since there are no particular restrictions on the shape or material of the slipper body, a variety of designs and sizes are possible. It is expected that they will become popular not only as simple cleaning slippers, but also as fashionable slippers with cleaning functions. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, an embodiment of the present invention will be described, with reference numerals indicating the same items regardless of the drawings.

[0024] As shown in Figs. 1 to 3, the slippers of the present invention have a double bottom sole.

[0025] A board bottom sole 3 of the same size or slightly smaller shape and made of the same material is added under the bottom sole 2 of the slipper body 1, taking into account the bulge of the cleaning sheet covering the board bottom sole 3, and connected by crossed sheet-like fasteners as shown in Figures 2, 4, 5, and 6.

[0026] The material for the bottom sole 2 of the main body and the bottom sole 3 of the board body is not particularly limited, and any general material for the bottom sole of the main body may be used as long as it has a suitable hardness, can accommodate the sheet-like fixing device 4, magnets 5, and ferromagnetic material 6, and is cost-effective.

[0027] The cross-type sheet-like fasteners 4 that fasten the bottom bottom 2 of the main body and the bottom bottom 3 of the board body are sheet-like, as shown in Figures 5 and 6, each of which is made to the full width of the bottom bottom 2 of the main body, and multiple sheets are arranged to match the vertical length of the bottom bottom 2 of the main body and the width of the sheet-like fasteners 4.

[0028] The width of this sheet-like fixture itself should be about 30 to 40 mm, so that there is enough space for the fingers to pinch and push the cleaning sheet in, and for the fingers to pinch the cleaning sheet on the other side to adjust any slack.

[0029] As for the material to be used, a thin, flexible, non-stretchable, and durable material such as polypropylene or polycarbonate is suitable.

[0030] As shown in Figures 5 and 6, each of these sheet-like fixtures 4 is fixed in one place on each of the symmetrical horizontal edges of the lower bottom surface 7 of the main body and the upper surface of the lower bottom 3 of the board body, and the adjacent sheet-like fixture is fixed in the opposite symmetrical position with a gap of about several millimeters, and the subsequent sheet-like fixtures 4 are crossed and fixed in the same manner.

[0031] Providing a gap between adjacent sheet-like fixing devices 4 is an essential element for creating some slack in the cleaning sheet when one side of the cleaning sheet is attached, preventing one side from becoming difficult to open after the other side has been set, and making it easier to adjust the slack in the cleaning sheet.

[0032] The lower base 2 of the main body is structured so that the lower base 3 is suspended by crossed sheet-like fixing devices 4. Under normal circumstances, the sheet-like fixing devices 4 are placed between them, but because they are made of a thin material, from the outside they appear to be tightly fitted with no gaps, as shown in Figures 1 and 3.

[0033] If the centres of the main body bottom sole 2 and the board bottom sole 3 were fixed directly without the sheet-like fixing device 4, the double bottom would naturally fit tightly, but the gap could only be opened slightly, making it difficult to push the cleaning sheet all the way in, much less cross the cleaning sheet itself. However, with slippers using the sheet-like fixing device 4, if you intentionally try to open either the left or right side of the board bottom sole 3 as shown in Figure 4, it is possible to open only one side widely, and furthermore, as shown in Figures 9 and 11, not only can the cleaning sheet be easily inserted, but it can also be pushed in all the way, dramatically improving the ease of attaching and removing the cleaning sheet.

[0034] Furthermore, as shown in FIG. 5, by partially hollowing out the central portion 10 of the sheet-like fixing device 4 to create a space, the cleaning sheet there can be picked up and pulled with fingers as shown in FIGS. 9, 11, and 12. This not only makes it possible to easily tighten the cleaning sheet sandwiched from the opposite side, but also creates a structure in which the cleaning sheets pressed in from the left and right come into direct contact with each other, which adds friction to the pressure during use and makes it even more difficult for the cleaning sheet to come off.

[0035] The cleaning sheet in the gap between the sheet-like fixtures 4, slightly visible at 12 in FIG. 10, can also be pulled in the same manner to enable the cleaning sheet to cover the lower bottom 3 of the board body without any loosening.

[0036] However, when walking in the slippers, if the slippers are floating, the bottom bottom 2 of the main body and the bottom bottom 3 of the board body will separate slightly as shown in Figure 2 due to their structure, which not only makes the cleaning sheet more likely to come loose but also poses the risk of the user tripping over steps or the like at the front end of the bottom bottom 3 of the board body. Therefore, as shown in Figure 4, magnets and ferromagnetic material installation locations 5 and 6 are provided at two locations on each of the front and rear ends of the bottom bottom 7 of the main body in Figure 5 and the top surface of the bottom bottom 3 of the board body in Figure 6, and the magnets are attached so that the bottom bottom 7 of the main body and the bottom bottom 3 of the board body come into close contact with each other through magnetic force, firmly holding the cleaning sheet in place.

[0037] As long as both ends of the double bottom can be firmly attached to each other, the mating part 6 may be made of either a magnet or a ferromagnetic material such as an iron material.

[0038] In order to make the slippers look beautiful and to prevent the board body bottom sole 3 from coming apart from the main body bottom sole 2 and becoming easy to trip over, the magnet fixing part is equipped so that the magnet is embedded, and there is no gap when the bottom sole and the board body bottom sole are tightly attached to each other.

[0039] The sheet-like fixing devices 4 are crossed, and when a cleaning sheet is sandwiched deep into the left and right sides of the slippers, the cleaning sheet itself automatically crosses up and down with the sheet-like fixing device sandwiched between them, as shown in Figure 11. As a result, the cleaning sheet sandwiched on the sides is less likely to come off during use, but the increased adhesion caused by the magnets reinforces the clamping force at both ends, which is weak due to the structure, and the cleaning sheet can be clamped more stably overall.

[0040] By fitting the cleaning sheet tightly in this way, the appearance of slippers with cleaning sheets attached can be changed from the state shown in Figs. 12 and 13 to that shown in Figs. 1 and 3, and it is possible to easily achieve a neat and unified appearance of slippers with cleaning sheets that will not cause any problems in daily use.

[0041] On the other hand, since the cleaning sheet itself is simply attached by pressing it down, there is no snagging and removing the cleaning sheet is stress-free and easy, as you just need to open one side of the slipper a little and pinch and pull one point on the cleaning sheet.

[0042] At that time, the edge of the cleaning sheet that is pinched with the fingers is the part that is clamped between the lower bottom 2 of the main body and the lower bottom 3 of the board body, so dirt does not adhere to the edge, and the used cleaning sheet can be removed without getting the fingers dirty.

[0043] After repeated prototyping, it was found that locating magnets on the sides of the slippers was good for holding the cleaning sheet firmly, but that having too many magnets on the sides increased the feeling of the cleaning sheet getting caught when removing it. Therefore, by equipping the slippers with two magnets with strong magnetic force on the front and back of the tip, as well as equipping them with a cross-type sheet-like fastener 4, it was found that the cleaning sheet could be attached securely and removed with light force, making this structure particularly comfortable to put on and take off.

[0044] The product of the present invention has the features that it does not require special materials for production and has a very high degree of freedom in design as long as the necessary requirements are met, so it can be widely used by a wide range of targets, from simple cleaning slippers to fashionable slippers with cleaning functions.

[0045] "How to use this invention" (a) As shown in FIG. 7, the slipper body 1 is placed on the cleaning sheet 11. (b) As shown in Figure 8, open the right side of the double bottom of the slipper body 1, which is the lower bottom 2 of the main body and the lower bottom 3 of the board body, and push the end of the cleaning sheet from the tip of the slipper into the open space and pinch it in place, as shown in Figure 9. (c) Next, open the left side of the double bottom portion on the left side of the slipper body 1, consisting of the lower bottom 2 of the main body and the lower bottom 3 of the board body, and push the protruding end of the cleaning sheet into the open space starting from the tip of the slipper as shown in Figure 10, sandwiching it in place. (ii) At this time, while firmly stretching the cleaning sheet so that it does not become loose, push in the edge of the cleaning sheet to cover the lower bottom 3 of the board body as shown in Figure 11, and pinch the cleaning sheet inserted from the right side, where it is already sandwiched between the cut-out space 10 of the sheet-like fastener 4 between the open double bottoms shown in Figure 12 and the gaps between the sheet-like fasteners 4 arranged side by side, with your fingers and pull it to remove any slack, so that the cleaning sheet fits snugly against the lower bottom 3 of the board body and installation is complete as shown in Figure 13. (e) After that, by putting on the slippers and walking as usual, dirt, dust, hair, pet hair, and the like on the floor can be entangled with the cleaning sheet. (e) If you are concerned about dirt on the floor, you can increase the cleaning effect by consciously sliding your feet over the area like a wiper or skating. (g) If the cleaning sheet becomes loose during use, it is possible to easily adjust the cleaning sheet to fit again and restore a beautiful appearance by opening one side of the lower base 3 of the board body as shown in Figure 12 and pushing in the end of the cleaning sheet or by pulling the end of the cleaning sheet on the other side. (h) When the cleaning sheet becomes noticeably dirty, removal can be completed by simply opening any one side of the lower bottom 3 of the board body to replace it, and picking up and pulling the part of the cleaning sheet that was clamped.
