Abstract
Description
[Technical Field]
[0001] The present invention relates to a portable mat, and more particularly to a technology that makes it easy to take out and less noticeable when stored. [Background technology]
[0002] In the past, when sitting down to take a break outdoors, if the ground or rocks were wet or dirty, you had to take a cushion mat out of your backpack or pocket to protect it from dirt. To make mats more portable, some mats are foldable or can be expanded with air, etc. However, it is a hassle to take them out of a bag and unfold them every time you take a break. There is also a method of fastening the mat to the waist using a belt, etc. This method is convenient because there is no need to take out the mat when sitting down, but the mat is noticeable around the waist, it looks unattractive, and it is difficult to use. Therefore, there was a demand for a mat that was easy to take out and looked nice when not in use.
[0003] Various techniques have been proposed to address these problems. For example, a portable outdoor mat (see Patent Document 1) has been proposed and is known as a known technique. More specifically, this portable mat allows users to sit or lie on the mat outdoors without getting dirty, eliminates the hassle of holding the mat or putting it in a container, and eliminates the need to take it out of the container. The portable mat is configured to include a belt connected to the folding mat, a latch located at the end of the belt, and a shock cord for bundling the folding mat. However, according to the above technical proposal, the task of bundling the mat with the shock cord becomes cumbersome if it is done repeatedly, and the above problem has not yet been fundamentally solved. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Registered Utility Model No. 3244274 Summary of the Invention [Problem to be solved by the invention]
[0005] To solve the above problems, the present invention aims to provide a portable mat that requires less effort to take out the mat when sitting down and that does not look unattractive when not in use. [Means for solving the problem]
[0006] In order to solve the above-mentioned problems, the present invention provides a portable mat for use when sitting outdoors, which comprises a flat mat portion that is elastic, heat-insulating, and deformable, and a belt portion for fastening the mat portion to a person's waist, the belt portion being disposed near an end of the mat portion in the longitudinal direction, and the mat portion being fastened to the waist portion by the belt portion so that the belt portion is on top, and in a state where it is fastened to the waist portion, the mat portion can be folded in two along a folding line in the middle portion in the up-down direction, the part above the folding line being the upper mat portion and the part below being the lower mat portion, and the mat portion has a stored state in which the upper and lower mat portions are folded, and an open use state, and in the use state, the surface that abuts against the waist portion is the inside and the opposite side is the inside. in the folded state, the upper and lower mat portions are folded around the fold line as an axis so that their respective outsides meet, and the upper mat portion is transformed into an arc-shaped cylinder with the inside being its inner diameter so as to cover the side of the waist portion, the fold line being an axis, and the lower mat portion connected to the fold line is transformed into an arc-shaped cylinder with the outside being its inner diameter, and the lower mat portion maintains its folded state due to the arc-shaped fold line, and both surfaces of the mat portions are vapor-deposited with aluminum, and in the folded state, the upper and lower mat portions are fastened together by hook-and-loop fasteners positioned opposite each other.
[0007] In addition, the present invention employs a means in which, when the mat portion is in use, both sides of the upper mat portion are located between the waist portion and the belt portion, and the belt portion urges both sides of the upper mat portion toward the waist portion, pressing both sides of the upper mat portion against the waist portion, causing the mat portion to deform into an arc-shaped cylinder so as to cover the sides of the waist portion.
[0008] Furthermore, the present invention employs a measure in which the length of the lower mat portion is shorter than that of the upper mat portion in the longitudinal direction of the mat portion.
[0009] Furthermore, the present invention employs a means for providing a folded portion at the end of the mat portion on the side of the upper mat portion, and for the folded portion to cover and hold the edge of the lower mat portion when the mat portion is in the stored state.
[0010] Furthermore, the present invention employs a means for providing two holes at the top of the upper mat portion, and for the belt portion to pass through the two holes and pass between the two holes on the side that contacts the waist portion. [Effects of the Invention]
[0011] The portable mat of the present invention is convenient and allows you to easily take a rest outdoors, as it requires less effort to take out the mat when you sit down and the appearance of the mat when not in use is not a concern. [Brief explanation of the drawings]

[0013] The portable mat according to the present invention has the greatest feature that it requires less effort to take out the mat when sitting down and does not look unattractive when not in use. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a portable mat according to the present invention will be described with reference to the drawings. The overall structure and the structure of each part of the portable mat of the present invention are not limited to the examples described below, but can be modified as appropriate within the scope of the technical concept of the present invention, i.e., within the scope of shapes, dimensions, structures, etc. that can achieve the same functional effects. In this embodiment, the upper and lower sides refer to the upper and lower sides when a person is standing wearing the portable mat. When the portable mat is unfolded, the side that comes into contact with the person is the inside, and the opposite side is the outside.
[0014] The present invention will be described with reference to FIGS.

FIG. 3 shows changes in the shape of the portable mat according to the present invention, where (a) is a schematic side view and (b) is a cross-sectional view of the mat portion. FIG. 4 is a side view showing another embodiment of the portable mat according to the present invention.
[0015] The portable mat 1 is a mat used when sitting down outdoors, and is always fixed to the waist, folded when not in use, and unfolded when in use, and placed between the seat and the user. The portable mat 1 is composed of a flat mat part 10 that is elastic, heat-insulating, and deformable, and a belt part 40 for fixing the mat part 10 to a person's waist K. The mat part 10 prevents the lower back and other parts from getting dirty when sitting. The size is about 50 cm in length and 35 cm in width. In the unbiased state, it is flat. The longitudinal direction is the length from the waist to the thighs, and the width direction is long enough to cover a part of the side of the waist. The thickness is about 5 to 10 mm. The material is, for example, urethane foam, which has enough elasticity to absorb the unevenness of the ground or rocks to some extent. It also has insulating properties that can reduce the coldness of the ground and rocks in winter. The base of the mat part 10 is a heat insulating part 12, and both sides of the mat part 10 are coated with aluminum vapor deposition 13 (FIG. 3(b)). The application of aluminum vapor deposition 13 can improve the waterproofing effect. In addition, the smooth surface reduces adhesion of dirt from the ground or rocks, and further improves the heat insulation effect.
[0016] 1(a), the mat part 10 has a generally rectangular shape that is long in the vertical direction. Belt parts 40 are arranged near the longitudinal ends of the mat part 10. The mat 10 is fixed to the waist K by the belt 40 so that the belt 40 faces upward (FIG. 1(b)). When the mat section 10 is fixed to the waist K by the belt section 40, the mat section 10 can be folded in two at a folding line 11 that extends horizontally in the vertical middle section. The part above the folding line 11 is the upper mat section 20, and the part below the folding line 11 is the lower mat section 30. The mat section 10 has a storage state in which the upper mat section 20 and the lower mat section 30 are folded, and a usage state in which the upper mat section 20 and the lower mat section 30 are opened. The stored state is when the mat is not in use, but is worn or carried. The mat is used outdoors, laid on the ground, etc., and the user sits down on it. The mat is always attached to the waist, so the user sits down with the mat sandwiched between the ground, etc. and the body. In use, the surface of the mat part 10 that comes into contact with the lower back K is referred to as the inner surface, and the opposite surface, that is, the surface that comes into contact with the ground or the like, is referred to as the outer surface. Near the end of the upper mat part 20, there are two belt holes 22 along the end. The two belt holes 22 are holes for passing the belt part 40 through. By passing the belt part 40 through the two belt holes 22, the belt part 40 and the mat part 10 become one unit.
[0017] In the stored state, the upper mat part 20 and the lower mat part 30 are folded so that their outer sides meet. A plurality of hook-and-loop fasteners 21 are arranged on the outer side of the upper mat part 20, and a plurality of hook-and-loop fasteners 31 are arranged on the outer side of the lower mat part 30. The hook and loop fasteners 21 and 31 are arranged in positions facing each other in the stored state, and are fixed by fitting them together so that they will not come apart accidentally. When using the mat part 10 for outdoor resting or the like, it is placed in the ready-to-use state as shown in Figure 2(b). After the resting or the like is over, the lower mat part 30 is lifted around the fold 11 as an axis and aligned with the upper mat part 20 as shown in Figure 3(a). Since hook-and-loop fasteners are provided on the outer sides 15 of the upper mat part 20 and the lower mat part 30, they can be fastened simply by aligning the outer sides 15 of the upper mat part 20 and the lower mat part 30, making the work easy. Furthermore, when it is time to take another break, the hook-and-loop fastener can be removed simply by pulling the lower mat portion 30 away from the upper mat portion 20, making the operation easy. In addition, when in use, the mat can cover the area from the waist to the thighs, significantly reducing dirt when sitting on the ground. Furthermore, in the stored state, the size of the mat portion 10 is reduced to about half, making it compact and less noticeable. In addition, since the mat part 10 is shaped to fit the waist part K, it does not protrude from the body and is not conspicuous. Furthermore, since it is shaped to fit the body, it can be easily hidden under a jacket as shown in Figure 3(a), making it less conspicuous.
[0018] The base of the mat part 10 is made of a urethane material or the like, and serves as the heat-insulating part 12. Both sides of the heat-insulating part are coated with aluminum vapor deposition 13 (Fig. 3(b)). The aluminum vapor deposition makes the surface smooth, which is preferable as it makes it less susceptible to dirt when laid on the ground. Furthermore, the aluminum vapor deposition 13 can enhance the heat-retaining effect. Moreover, by using aluminum vapor deposition 13, the waterproof effect can be improved.
[0019] The belt portion 40 is for fixing the mat portion 10 to the waist K. The overall length of the belt portion 40 is long enough to wrap around approximately the stomach of a person. The belt portion 40 passes through the two belt holes 22. Between the two belt holes 22, the belt portion 40 is on the inside, which is the side that contacts the waist K. In the portion away from the two belt holes 22, the belt portion 40 is arranged on the outside of the upper mat portion 20. There are locking parts 41 at both ends, and by connecting the ends of the belt part together at the locking parts 41, the belt part 40 is fixed to the waist part K. The mat part 10 fixed to the belt part 40 is also fixed to the waist part K, and the mat part 10 can be carried at all times without using hands.
[0020] 1(b) is a schematic diagram showing the portable mat 1 worn by a person H. The mat is fixed to the waist K by a belt 40 attached to the upper part of the mat 10. This shows the stored state, in which the mat 10 is folded. The dotted line at the bottom shows the unfolded state, that is, the state in use. As shown in FIG. 2(c), the belt portion 40 is fixed so as to cover the side edge 23 of the mat portion 10, so that the mat portion 10 as a whole takes a shape that follows the horizontal shape of the lower back K. In other words, when the mat part 10 is in use, both side edges 23 of the upper mat part 20 are located between the lumbar region K and the belt part 40, and the belt part 40 urges both side edges 23 of the upper mat part 10 toward the lumbar region K, pressing both side edges 23 of the upper mat part 20 against the lumbar region K, causing the mat part 10 to deform into an arc-shaped cylinder to cover the side surfaces of the lumbar region K.
[0021] The effect of the mat portion 10 being in the shape of a circular arc cylinder both in the stored state and in the use state will be described. Generally, thin, planar objects can be easily deformed and can be changed between a folded state and an unfolded state with little force. Therefore, in the stored state of this embodiment, if the mat portion 10 is flat, when the hook-and-loop fastener comes loose, it is thought that the lower mat portion 30 will easily separate from the upper mat portion and open downward. Generally, it is believed that strength increases when something is shaped like a cylinder, an arc-shaped cylinder, etc. For example, when trying to fold an arc-shaped object, the part that serves as the folding axis must be deformed and first straightened before it can be easily folded. Furthermore, when trying to unfold an arc-shaped cylindrical object after folding it, the part that serves as the folding axis must be deformed and first made straight, otherwise it cannot be easily unfolded. In this embodiment, this principle is used to provide a portable mat that can be easily maintained in a stored state.
[0022] Specifically, in the stored state, the upper part of the upper mat part 20 is deformed by the belt part 40 so as to fit along the side of the lumbar region K, as shown in Fig. 2(c). This shape is roughly an arc-shaped cylinder. The upper mat portion 20 is in the form of a deformable flat plate, so that when the upper portion of the upper mat portion 20 is deformed into an arc-shaped cylinder, the entire upper mat portion 20 is also deformed into an arc-shaped cylinder. As a result, the fold line 11 at the end of the upper mat portion 20 also becomes a curve similar to a circular arc cylindrical shape. Since the fold line 11 is also the end of the lower mat 40, the entire lower mat 40 is also deformed into an arc-shaped cylinder. Therefore, the overall shape is two overlapping circular arc cylindrical plates, as shown in Figure 2(a). In this state, if the fastening by the hook-and-loop fastener 21 comes loose, the lower mat portion 40 will try to rotate downward around the folding line 11 as an axis due to its own weight. However, since the fold line 11 is curved, it must become straight in order for it to rotate. The curved shape of the fold line 11 is restricted by the force applied to the upper mat part 20 by the belt part 40, so it will not deform into a straight line just by the weight of the lightweight lower mat part. Therefore, the lower mat portion 30 can maintain the stored state even without the hook-and-loop fastener 21. Therefore, the user can be assured that the lower mat portion 30 will not unfold unintentionally, improving convenience. To change from the stored state to the used state, simply press down the lower mat portion 30 by hand. If the urethane foam is about 5 mm thick, it can be easily deformed by hand, so the fold line 11 can be easily deformed into a straight line, and the lower mat portion 30 can be unfolded. In this way, in the stored state, for example, even if the hook and loop fastener comes off, the position of the lower mat portion 30 can be maintained, which is convenient.
[0023] In the longitudinal direction of the mat portion 10, the length of the lower mat portion 30 is shorter than that of the upper mat portion 20. This is preferable because dirt from the ground and the like does not adhere to clothes. Figure 3(a) shows the stored state, with the end of the lower mat portion 30 being lower than the end of the upper mat portion 20. Dirt from the ground and the like adheres to the outer side 15 of the lower mat portion 30. If the length of the lower mat portion 30 were longer than the upper mat portion 20, the outer side of the lower mat portion 30 would climb over the upper mat portion 20 and come into contact with the user's clothes during storage. Since the outer side of the lower mat is the side that comes into contact with the ground and the like, if it is dirty, there is a risk that it will adhere to clothes. However, by making the length of the lower mat portion 30 shorter than that of the upper mat portion 20, as shown in Figure 3(a), all of the dirty surface, which is the outer side 15 of the lower mat portion 30, is received by the lower mat portion 30, so clothes will not get dirty with dirt on the lower mat portion 30.
[0024] Furthermore, a folded portion 24 may be provided at the top of the upper mat portion 20 as a structure for further improving the stability of the lower mat portion 30 in the folded state. As shown in Figure 4, by providing a folded portion 24 at the top of the upper mat portion 20, the upper end of the lower mat portion 30 can be held down by the folded portion 24 when folded, so that the lower mat portion 30 will not come off the upper mat portion 20 even if you move your body a lot. Furthermore, since the outer side 15 of the lower mat portion 30 is completely covered by the folded portion 24, dirt adhering to the lower mat portion 30 does not transfer to clothes at all, which is preferable.
[0025] As described above, the portable mat of the present invention is folded in half and can be attached to a belt, allowing both hands to be kept free at all times, ensuring safety. Furthermore, no carrying case is required; simply attaching it to the waist makes it easy to use and allows for immediate sitting. When standing up and starting to walk, it can be quickly folded and stored, saving extra time. Its light weight means it can be worn by anyone, regardless of age or gender. It also keeps the lower back and hips warm, and its waterproof design prevents the clothes from becoming heavy due to dirt or water, reducing physical fatigue. Furthermore, when using it on the lift while skiing or snowboarding, it is extremely convenient as it prevents your clothing from getting wet even if there is water or snow on the chair.What's more, it can be folded up so it doesn't get in the way while skiing or snowboarding.
[0026] Furthermore, with the portable mat of the present invention, there is less need to take out the mat when sitting down, and the appearance of the mat when not in use is not an issue, making it convenient and easy to take a rest outdoors.
[0027] Furthermore, since the sides of the upper mat portion are pressed toward the waist, the entire mat conforms to the horizontal shape of the waist, resulting in fewer irregularities and a less uncomfortable appearance, making it more convenient.
[0028] Furthermore, the lower mat is shorter in the vertical direction than the upper mat, which is convenient as it prevents clothes from getting dirty when stored.
[0029] Furthermore, the presence of the folded portion on the upper mat prevents the lower mat from accidentally separating from the upper mat, and prevents clothes from becoming soiled by dirt on the lower mat. [Industrial Applicability]
[0030] The portable mat of the present invention is easy to carry and maintain in both its usable and storable state, requiring little effort to take out the mat when sitting down, and is aesthetically pleasing when not in use, making it usable in a wide range of fields, including everyday life, going out to events, winter sports such as skiing, and outdoor activities such as mountain climbing and camping. Therefore, it is believed that the present invention has great industrial applicability. [Explanation of symbols]
