Description

[Technical field]

[0001] The present invention relates to a portable mat, and more particularly to a technology for making it easy to take out and less noticeable when stored. [Background technology]

[0002] In the past, when sitting down to rest outdoors and the ground or rocks were wet or dirty, you had to take a cushion mat out of your backpack or pocket to prevent it from getting dirty. To make mats easier to carry, some mats were foldable or could be unfolded using air, etc. However, it was time-consuming to take them out of a bag and unfold them every time you wanted to take a break. There was also a method of fixing the mat to the waist using a belt, etc. This method was convenient because it was not necessary to take out the mat when sitting down, but the mat was conspicuous on the waist, looked unattractive, and was difficult to use. Therefore, there was a demand for a mat that required less effort to take out and that looked good when not in use.

[0003] To address these problems, various techniques have been proposed in the past. For example, a portable mat for outdoor use (see Patent Document 1) has been proposed and is a publicly known technique. More specifically, this portable mat allows a user to sit or lie on the mat without getting dirty when sitting outdoors, eliminates the hassle of holding the mat or putting it in a container, and eliminates the trouble of taking it out of the container. The portable mat is configured to include a belt connected to the folding mat, a stopper disposed 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 performed repeatedly, and the above problem has not yet been fundamentally solved.

[0005] To provide a portable mat that solves the above problems and that requires less time 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, comprising 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 vertical direction when the mat is fixed to the waist is defined as the longitudinal direction. The belt portion is disposed near the longitudinal end of the mat portion, and the mat portion is fixed to the waist portion by the belt portion so that the belt portion is at the top. When fixed to the waist portion, the mat portion can be folded in two at a folding line in the vertical middle portion, with the upper mat portion above the folding line and the lower mat portion below. The mat portion has a stored state in which the upper mat portion and the lower mat portion are folded, and an open usage state, and in the usage state, the surface that contacts the waist portion is the inside and the opposite side is the outside. In the usage state, the mat portion is an arc-shaped cylinder with the inside as the inner diameter so as to cover the side of the waist portion. In the stored state, the upper mat portion and the lower mat portion are folded about the fold line so that their respective outsides meet, and the upper mat portion is deformed into an arc-shaped tube with the inside as its inner diameter so as to cover the side of the waist portion, the fold line becoming arc-shaped, and the lower mat portion connected to the fold line is deformed into an arc-shaped tube with the outside as its inner diameter, and the lower mat portion maintains its folded state due to the arc-shaped fold line, and both sides of the mat portion are aluminum-vapor-deposited, and in the stored state, the upper mat portion and the lower mat portion are fixed together by hook-and-loop fasteners arranged in positions facing each other.

[0007] In addition, the present invention employs a means in which, when the mat portion is in use, both side edges of the upper mat portion are located between the waist portion and the belt portion, and the belt portion urges both side edges of the upper mat portion toward the waist portion and presses both side edges 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 side surfaces of the waist portion.

[0008] Furthermore, the present invention employs a means for making the length of the lower mat portion shorter than that of the upper mat portion in the longitudinal direction of the mat portion.

[0009] Furthermore, the present invention employs a means in which the end of the mat part facing the upper mat part has a folded portion, and when the mat part is in the stored state, the folded portion covers and holds the end edge of the lower mat part.

[0010] Furthermore, the present invention employs a means for providing two holes in the upper part of the upper mat part, and for the belt part to pass through the two holes and pass between the two holes on the side that contacts the waist part. Effect of the Invention

[0011] The portable mat of the present invention is convenient because it requires less effort to take out the mat when sitting down and the mat looks unnoticeable when not in use, making it easy to take a rest outdoors. [Brief description of the drawings]

[0013] The portable mat according to the present invention has the greatest features that it requires less time 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 configuration and the configuration 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 idea of ​​the present invention, i.e., within the scope of shapes, dimensions, structures, etc. that can achieve the same functional effects.

FIG. 4 is a schematic 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 which is elastic, heat insulating and deformable, and a belt part 40 for fixing the mat part 10 to a person's waist part K. The mat portion 10 prevents the lower back and other parts of the body from getting dirty when sitting. The size is approximately 50 cm in the longitudinal direction and 35 cm in the transverse direction. 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, and has enough elasticity to absorb the unevenness of the ground and rocks to some extent. It also has sufficient insulation to reduce the coldness of the ground and rocks during winter. The base portion of the mat portion 10 is a heat insulating portion 12, and both sides of the mat portion 10 are coated with aluminum 13 (FIG. 3(b)). The application of aluminum vapor deposition 13 can improve the waterproofing effect. In addition, the smooth surface can reduce adhesion of dirt from the ground or rocks, and can also improve the heat insulation effect.

[0016] 1(a), the mat part 10 has an overall rectangular shape that is long in the vertical direction. A belt part 40 is disposed near the end of the mat part 10 in the longitudinal direction. The mat 10 is fixed to the waist K by the belt part 40 so that the belt part 40 faces upward (FIG. 1(b)). When the mat part 10 is fixed to the waist part K by the belt part 40, the mat part 10 can be folded in two at a folding line 11 extending horizontally in the vertical middle part. The part above the folding line 11 is the upper mat part 20, and the part below the folding line 11 is the lower mat part 30. The mat part 10 has a storage state in which the upper mat part 20 and the lower mat part 30 are folded, and a usage state in which the upper mat part 20 and the lower mat part 30 are opened. The stored state is when the mat is not in use and is worn or carried. The mat is used outdoors, laid on the ground, etc., and the person sits down on it. Since the mat is always attached to the waist, the person sits down with the mat 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 defined as the inside, and the opposite surface, that is, the surface that comes into contact with the ground or the like, is defined as the outside. 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 integrated.

[0017] In the stored state, the upper mat portion 20 and the lower mat portion 30 are folded so that their outer sides meet each other. A plurality of hook-and-loop fasteners 21 are arranged on the outer side of the upper mat portion 20, and a plurality of hook-and-loop fasteners 31 are arranged on the outer side of the lower mat portion 30. The hook-and-loop fasteners 21 and 31 are disposed opposite each other in the stored state, and are fixed together by fitting them together so that they will not come apart inadvertently. When using the mat part 10 for outdoor resting etc., it is used in the usage state as shown in Fig. 2(b). After resting etc. is finished, as shown in Fig. 3(a), the lower mat part 30 is lifted around the fold 11 as an axis and combined with the upper mat part 20. Since hook-and-loop fasteners are arranged on the outside 15 of the upper mat part 20 and the lower mat part 30, they can be fixed simply by combining the outside 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 that occurs when sitting on the ground, etc. Furthermore, in the stored state, the size of the mat portion 10 is reduced to about half, making it compact and less noticeable visually. In addition, since the mat 10 is shaped to fit the waist K, it does not protrude from the body and is not conspicuous. Furthermore, since it is shaped to fit the body, it is easily hidden under a jacket as shown in Fig. 3(a), and is therefore not conspicuous.

[0018] The base of the mat 10 is made of a urethane material or the like, and serves as the heat-insulating portion 12. Both sides of the heat-insulating portion are coated with aluminum vapor deposition 13 (Fig. 3(b)). Coating with aluminum vapor deposition makes the surface smooth, which is preferable since it makes it difficult for dirt to adhere to the surface when the mat is laid on the ground or the like. Coating with aluminum vapor deposition 13 also enhances the heat-retaining effect. Moreover, by applying 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 portion K. The overall length of the belt portion 40 is long enough to wrap around approximately a person's stomach. The belt part 40 passes through the two belt holes 22. Between the two belt holes 22, the belt part 40 is on the inside, which is the side that contacts the waist part K. In the portion away from the two belt holes 22, the belt part 40 is disposed on the outside of the upper mat part 20. There are locking parts 41 at both ends, and the ends of the belt part are connected to each other at the locking parts 41, thereby fixing the belt part 40 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 a 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 used state. 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 has a shape that fits the horizontal shape of the lumbar region K as a whole. 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 waist area K and the belt part 40, and the belt part 40 urges both side edges 23 of the upper mat part 10 toward the waist area K, pressing both side edges 23 of the upper mat part 20 against the waist area K, causing the mat part 10 to deform into an arc-shaped cylinder so as to cover the side surfaces of the waist area K.

[0021] The effect of the mat portion 10 having an arcuate cylindrical shape both in the stored state and in the used state will be described. Generally, thin, planar objects can be easily deformed and can be folded and unfolded 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 believed that the lower mat portion 30 will easily separate from the upper mat portion and open downward. By the way, it is generally believed that strength increases when it is made into a cylindrical shape, an arc-shaped tube, etc. For example, when trying to fold an arc-shaped tube, the part that will be the axis of folding must be deformed and made straight once, otherwise it cannot be folded easily. Furthermore, when attempting to unfold the curved cylindrical shape after folding, the folding axis must be deformed and first straightened out before it can be easily unfolded. In this embodiment, this principle is used to create a portable mat that is easy to maintain in a stored state.

[0022] Specifically, in the stored state, the upper portion of the upper mat portion 20 is deformed by the belt portion 40 so as to fit the side of the waist portion K, as shown in Fig. 2(c). This shape is generally an arc-shaped cylinder. Since the upper mat portion 20 is in the form of a deformable flat plate, when the upper portion of the upper mat portion 20 is deformed into an arcuate cylindrical shape, the entire upper mat portion 20 is also deformed into an arcuate cylindrical shape. 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 cylinder. Since the fold line 11 is also the end portion 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 cylindrical plates, as shown in Figure 2(a). In this state, if the hook-and-loop fastener 21 becomes detached, the lower mat portion 40 will attempt to rotate downwards around the folding line 11 as an axis due to its own weight. However, since the fold line 11 is curved, the fold line 11 must become straight in order 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 cannot be deformed into a straight line by the weight of the lightweight lower mat part alone. Therefore, the lower mat portion 30 can maintain the stored state even without the hook-and-loop fastener 21. Therefore, the lower mat portion 30 will not unfold unintentionally, improving convenience for the user. To change from the stored state to the used state, the lower mat portion 30 can be pushed down by hand. Since a urethane foam with a thickness of about 5 mm can be easily deformed by hand, the fold line 11 can be easily deformed into a straight line, and the lower mat portion 30 can be unfolded. In this manner, 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 section 10, the length of the lower mat section 30 is shorter than that of the upper mat section 20. This is preferable because dirt from the ground and the like does not adhere to clothes. FIG. 3(a) shows the stored state, and the end of the lower mat section 30 is lower than the end of the upper mat section 20. Dirt from the ground and the like adheres to the outer side 15 of the lower mat section 30. If the length of the lower mat section 30 is longer than that of the upper mat section 20, the outer side of the lower mat section 30 will climb over the upper mat section 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 part 30 shorter than that of the upper mat part 20, as shown in Figure 3 (a), all of the dirty surface, which is the outer side 15 of the lower mat part 30, is received by the lower mat part 30, so that clothes will not get dirty with dirt on the lower mat part 30.

[0024] Furthermore, a folded-back 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 portion of the lower mat portion 30 can be held down by the folded portion 24 when in the folded state, so that the lower mat portion 30 will not come off the upper mat portion 20 even if the body moves significantly. In addition, since the outer side 15 of the lower mat part 30 is completely covered by the folded part 24, dirt adhering to the lower mat part 30 is not transferred to clothes at all, which is preferable.

[0025] In this way, the portable mat of the present invention is folded in half and can be attached to a belt, so that both hands can be kept free at all times, and it is safe. In addition, no carrying case is required, and it can be easily put into use by attaching it to the waist, and it is possible to sit on it immediately. When standing up and starting to walk, it can be quickly folded and stored, so no extra time is wasted. In addition, because it is light, it can be used by anyone, regardless of age or gender. Furthermore, it has a heat-retaining effect on the lower back and buttocks, and its waterproof design prevents the clothes from becoming heavy due to dirt or moisture, reducing physical fatigue. Furthermore, when using it while skiing or snowboarding and riding the lift, it is extremely convenient because it prevents your clothing from getting wet even if there is water or snow on the chair. Moreover, 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 hassle in taking 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 break 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, with fewer irregularities and less of an uncomfortable appearance, making it more convenient.

[0028] Furthermore, since the lower mat is shorter in the vertical direction than the upper mat, clothes do not get dirty when stored, which is convenient.

[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 due to dirt on the lower mat. [Industrial Applicability]

[0030] The portable mat of the present invention is easy to carry and easy to maintain in use and stored state, and since there is little trouble of taking out the mat when sitting down and the appearance of the mat when not in use is not a concern, it can be used in a variety of fields, including when going out for daily life or events, winter sports such as skiing, and outdoor activities such as mountain climbing and camping. Therefore, it is understood that the present invention has great industrial applicability. [Explanation of symbols]
