Description

[Technical field]

[0001] The present invention belongs to the technical field of daily necessities, and specifically relates to interlocking floor tiles that can be folded, stacked and packed. [Background technology]

[0002] The aforementioned concept of folding, stacking and packing refers to the unused state of floor tiles in logistics such as warehouse storage, bulk transportation and single item delivery, while when used, the floor tiles will be interlocked and placed flat at the entrance or other required places without being folded or stacked.

[0003] Known floor tiles are generally in the form of a single piece, i.e., a whole plane, and this type of floor tile has the advantage of being well integrated and can be used as is after laying. However, floor tiles made of polyurethane (PUR), polyethylene foam (EPE), ethylene vinyl acetate copolymer (EVA), cross-linked polyethylene (XPE), ethylene-propylene-cyclopentadiene terpolymer (EPDM), etc., which have a relatively large area and a relatively large thickness, often have high logistics costs. In particular, since online shopping (online purchase) has the advantages of time saving, shopping safety, and relatively low cost, it is relatively common for consumers to purchase floor tiles through online shopping. However, as mentioned above, the area and thickness are relatively large, and they cannot be folded and stacked for packaging, which makes logistics difficult. In addition, for manufacturers, floor tile products need to be introduced into sales channels through logistics in bulk, and even exported overseas, so logistics costs often cause floor tile manufacturers to reduce their product competitiveness in the market. However, if the logistics costs are passed on to the end users, i.e. consumers, this mindset will definitely affect consumers' purchasing willingness, and ultimately affect the corporate image, reputation and production volume of floor tile manufacturers.

[0004] For these reasons, if floor tiles could be designed so that they are unfolded and laid at the entrance or other places when used by consumers, but can be folded (also called "folded") and stacked during logistics such as export to overseas, taking advantage of the height of the space to reduce the footprint, all of the above problems could be easily solved. Specifically, there would be no significant increase in transportation costs during the manufacturer's logistics process, no increase in logistics warehouse storage costs, and no increase in storage footprint, but rather a significant saving in the footprint during the warehouse storage process, and there would be no increase in sales costs for users.

[0005] There are many technical information about floor tiles belonging to the mat category in the published Chinese patent documents. A representative example is CN210631043U, which recommends "foldable floor tiles that are easy to store". However, although this patent can objectively achieve the technical effect described in paragraph 0007 of the specification, each adjacent floor tile unit (referred to as "sheet" in this patent) is transiently connected by the structure of the surface layer and back layer of the floor tile unit, and the foamed resin layer between adjacent floor tile units is not connected, so this unit connection method is like separating the bones and the flesh and connecting only the skin, which causes the following technical problems in floor tiles. First, since the connection part is essentially thermocompressed and composited through the above-mentioned surface layer and back layer, which are like a film, the connection part is very fragile and difficult to withstand the inevitable lateral force during actual use, that is, when it is stepped on. When the connection part is torn or damaged, it can only be removed or replaced. Secondly, the entire floor tile is composed of multiple (four in the figure) floor tile units, and large recesses are formed between two adjacent floor tile units and at the corresponding connection parts, so that dust accumulates in the groove-like recesses during daily use, bacteria grow, and it has a negative impact on hygiene. Thirdly, the existence of such groove-like recesses causes a problem that the edges feel uncomfortable when stepped on. Although not limited to the above situation, this CN210631043U has a disadvantage that if one is distracted by the other, the other is neglected. One is that it can be folded and unfolded, and the other is the technical problem mentioned above. Summary of the Invention [Problem to be solved by the invention]

[0019] In the following description, the concepts of directionality or orientation such as "up", "down", "left", "right", "front" and "rear" are all based on the positional state of FIG. 1 except for FIG. 4, and therefore cannot be understood as limiting the technical solution of the present invention.

[0020] 1 and 2, a floor tile unit storage mechanism 1 is shown, and the floor tile unit storage mechanism 1 includes a left sleeve 11, a right sleeve 12, and a sleeve cavity opening / closing mechanism 13. The left sleeve 11 has a side opposite to the floor when in use, i.e., a side facing upward when in use, which is the outer surface layer 111 of the left sleeve, and a side facing the floor when in use, which is the inner surface layer 112 of the left sleeve. The space between the outer surface layer 111 of the left sleeve and the inner surface layer 112 of the left sleeve is the left sleeve cavity 113, and the cavity opening of the left sleeve cavity 113 has a "┐" shape. The right sleeve 12 has a side opposite to the floor when in use, i.e., a side facing upward when in use, which is the outer surface layer 121 of the right sleeve, and a side facing the floor when in use, which is the inner surface layer 122 of the right sleeve. The outer surface layer 121 of the right sleeve and the inner surface layer 122 of the right sleeve are formed in a space between the outer surface layer 121 of the right sleeve and the inner surface layer 122 of the left sleeve. The space between the left sleeve 11 and the inner surface layer 122 of the right sleeve forms a right sleeve cavity 123, the cavity opening of the right sleeve cavity 123 is shaped like a letter "┌", the outer surface layer of the left sleeve and the outer surface layer of the right sleeve 111, 121 are configured as an integral structure, the inner surface layer of the left sleeve and the inner surface layer of the right sleeve 112, 122 are configured as separate structures, the sleeve cavity opening / closing mechanism 13 includes an opening / closing member 131 of the left sleeve cavity opening and an opening / closing member 132 of the right sleeve cavity opening, the opening / closing member 131 of the left sleeve cavity opening is provided in the left sleeve 11 at a position corresponding to the cavity opening of the left sleeve cavity 113, and the opening / closing member 132 of the right sleeve cavity opening is provided in the right sleeve 12 at a position corresponding to the cavity opening of the right sleeve cavity 123. A left floor tile unit 2 and a right floor tile unit 3 are shown.The left floor tile unit 2 includes a first module 21 of the left floor tile unit and a second module 22 of the left floor tile unit, and the opposing ends of the first and second modules 21, 22 of the left floor tile unit are interlocked with each other by dowel crimping and are positioned in the left sleeve cavity 113, and the right floor tile unit 3 includes a first module 31 of the right floor tile unit and a second module 33 of the right floor tile unit, and the opposing ends of the first and second modules 31, 33 of the right floor tile unit are interlocked with each other by dowel crimping and are positioned in the right sleeve cavity 123.

[0021] In this embodiment, the illustrated interlocking floor tile that can be folded and stacked for packaging is in the form of a two-fold (also called "double-fold") structure, and the two-fold structure form here means, but is not limited to, including only one left floor tile unit 2 and one right floor tile unit 3. For example, additional floor tile units may be added as necessary to accommodate three-fold, four-fold, etc., so Figures 1 and 2 are merely illustrative of a specific embodiment.

[0022] 1 and 2, a left side sleeve cavity opening horizontal left end sealing region 1131 is formed at the left side of the cavity opening of the left side sleeve cavity 113, and a left side sleeve cavity opening vertical lower end sealing region 1132 is formed at the lower vertical end of the cavity opening of the left side sleeve cavity 113. As can be seen, the left side of the upper horizontal end and the lower vertical end of the "┐" shaped cavity opening are left with areas for the opening / closing member 131 of the left side sleeve cavity opening, which serves to cover both ends of the opening / closing member 131 of the left side sleeve cavity opening when in use. A right lateral end sealed region 1231 of the right sleeve cavity opening is formed at the right lateral end of the cavity opening of the right sleeve cavity 123, and a lower lateral end sealed region 1232 of the right sleeve cavity opening is formed at the lower lateral end of the cavity opening of the right sleeve cavity 123. The right lateral end sealed region 1231 of the right sleeve cavity opening and the lower lateral end sealed region 1232 of the right sleeve cavity opening have the same functions as the left lateral end sealed region 1131 of the left sleeve cavity opening and the lower lateral end sealed region 1132 of the left sleeve cavity opening, respectively, and therefore will not be described in detail here.

[0023] As shown in FIG. 3, in the state of use, when the inner surface layer 112 of the left sleeve 11 and the inner surface layer 122 of the right sleeve 12 are both pressed against the entire floor, the vertical lower end sealing area of ​​the left sleeve cavity opening and the vertical lower end sealing areas 1132, 1232 of the right sleeve cavity opening are assigned to each other in an overlapping state.

[0024] In this embodiment, the opening and closing stroke (i.e., the "opening and closing area") of the opening and closing member 131 of the left sleeve cavity opening described above has its starting point at a position above the vertical lower end sealed area 1132 of the left sleeve cavity opening described above and its end point to the right of the horizontal left end sealed area 1131 of the left sleeve cavity opening described above, but it may also be that the starting point is to the right of the horizontal left end sealed area 1131 of the left sleeve cavity opening and the end point is above the vertical lower end sealed area 1132 of the left sleeve cavity opening. In this embodiment, the opening and closing stroke (i.e., the "opening and closing area") of the opening and closing member 132 of the right sleeve cavity opening starts from a position above the vertical lower end sealed area 1232 of the right sleeve cavity opening and ends to the left of the horizontal right end sealed area 1231 of the right sleeve cavity opening, but the starting point may also be to the left of the horizontal right end sealed area 1231 of the right sleeve cavity opening and the end point may be above the vertical lower end sealed area 1232 of the right sleeve cavity opening.

[0025] In this embodiment, the opening and closing member 131 of the left sleeve cavity opening and the opening and closing member 132 of the right sleeve cavity opening are zippers, and more specifically, nylon zippers. However, even if a metal zipper is used instead of the nylon zipper, it should be considered as the same technical means, falling within the scope of the technology disclosed in this invention.

[0026] In this embodiment, the left sleeve 11 and the right sleeve 12 are made of PU.

[0027] Continuing to refer to FIG. 1, the structures of the first and second modules 31, 32 of the right floor tile unit are the same as those of the first and second modules 21, 22 of the left floor tile unit, so only the first and second modules 21, 22 of the left floor tile unit will be described in detail below. The first module 21 of the left floor tile unit has a first module dowel 211 of the left floor tile unit and a first module hole 212 of the left floor tile unit formed at its end facing the second module 22 of the left floor tile unit, and the first module dowel 211 of the left floor tile unit and the first module hole 212 of the left floor tile unit are in a mutually arranged positional relationship, and the second module 22 of the left floor tile unit has a second module dowel 221 of the left floor tile unit and a left floor tile unit hole 212 of the left floor tile unit formed at its end facing the first module 21 of the left floor tile unit. A second module hole 222 of the lower tile unit is formed, the second module dowel 221 of the left floor tile unit and the second module hole 222 of the left floor tile unit are in a mutually arranged positional relationship, the first module dowel 211 of the left floor tile unit and the second module hole 222 of the left floor tile unit correspond to each other and are interlocked by dowel crimping, and the second module dowel 221 of the left floor tile unit and the first module hole 212 of the left floor tile unit correspond to each other and are interlocked by dowel crimping.

[0028] In this embodiment, the first module dowel 211 of the left floor tile unit and the first module hole 212 of the left floor tile unit are dovetail shaped.

[0029] The first and second modules 21, 22 of the left floor tile unit, and the first module 31 of the right floor tile unit and the second module 32 of the right floor tile unit are of the same shape and size and have a rectangular shape, more specifically, a cuboid shape.

[0030] In this embodiment, the material of the first and second modules 21, 22 of the left floor tile unit, the first module 31 of the right floor tile unit and the second module 32 of the right floor tile unit is EPE, that is, EPE foam, more specifically, polyethylene foam, and EPE foam is environmentally friendly. Of course, in this invention, if materials such as PUR, EVA, XPE or EPDM are used instead of EPE, it is a formal change rather than a substantial change.

[0031] With reference to Figures 3 and 4, as described above with respect to Figure 3, the present invention is placed or laid on the floor in the entrance or other similar areas. Also, as described above with respect to Figures 1 and 2 and as shown in Figures 1 and 2, the lower part of the width direction of the left sleeve cavity 113 and the right sleeve cavity 123 is not connected to the outside as a whole, and a "U"-shaped area is maintained at the height of the vertical lower end sealing area 1132, 1232 of the left sleeve cavity opening and the vertical lower end sealing area 1132, 1232 of the right sleeve cavity opening. Therefore, when observed from Figure 3, the end faces of the left floor tile unit and the right floor tile unit 2, 3 arranged inside the left sleeve cavity and the right sleeve cavity 113, 123, respectively, cannot be seen, so the appearance is very good.

[0032] FIG. 4 shows the above-mentioned storage bag 4 having a storage bag cavity 41, and a bag cover 42 is provided at the opening portion of the storage bag 4, i.e., the opening of the storage bag 4, and the bag cover 42 is connected to the bag opening of the storage bag 4 by a bag cover fastener 421, where connection means that the bag opening is opened and closed by the bag cover fastener 421.

[0033] 4, first, the opening / closing member of the left sleeve cavity opening and the opening / closing member of the right sleeve cavity opening 131, 132 are opened, that is, the fasteners which are the opening / closing member of the left sleeve cavity opening and the opening / closing member of the right sleeve cavity opening 131, 132 are opened, and the left floor tile unit and the right floor tile units 2, 3 are taken out. Next, the first module 21 of the left floor tile unit and the second module 22 of the left floor tile unit which constitute the left floor tile unit 2 are separated, that is, the interlocking of both of them is released, and similarly, the first module 31 of the right floor tile unit and the second module 32 of the right floor tile unit which constitute the right floor tile unit 3 are separated. Furthermore, the floor tile storage mechanism 1 is folded in half lengthwise, and then folded in half widthwise, and then the first and second modules 21, 22 of the left floor tile unit of the structural system of the left floor tile unit 2, the floor tile storage mechanism 1 in the folded state, the second module 31 of the right floor tile unit of the structural system of the right floor tile unit 3, and the first module 32 of the right floor tile unit are stacked from top to bottom as shown in Fig. 4, that is, from the top, the first module 21 of the left floor tile unit, the first module 31 of the right floor tile unit, the above-mentioned folded floor tile storage mechanism 1, the second module 22 of the left floor tile unit, and the second module 32 of the right floor tile unit. Furthermore, when it is stored in the storage bag 4 and the bag cover fastener 421 is closed, it is changed from the usage state to the storage state.

[0034] However, usually, the products of the present invention produced by the manufacturer are stacked in the state shown in Fig. 4, then stored in the storage bag 4, the bag cover fastener 421 is closed, and the product is subjected to the above-mentioned logistics. After the user obtains the product, the user can simply assemble it as described above, and the product can be used in the state shown in Fig. 3.
