Description

  The present invention relates to a split-type rug, and in particular, relates to a split-type rug that can flexibly correspond to various sizes depending on usage.

  Many rugs such as mattresses and mattresses are made in a size of, for example, 100 cm × 200 cm in accordance with a standard body size (height is approximately 160 to 170 cm).

  If the user is a short child or a tall adult, the standard size is inappropriate.

  When the rug is not used, it is stored in a closet with the rug folded in half or in three. The rug cannot be stored in the closet.

  Of the parts of the rug, the part that is most likely to be worn away by use is the central part that contacts the waist or buttocks where the user's center of gravity is loaded. Is the upper part that contacts the head, and the part that is most difficult to wear is the lower part that contacts the leg. If it is a single piece of rug, if the center part wears and falls, even if the other parts are lightly worn, the cover of the rug is exchanged or the entire rug is stopped and discarded. Often, it is very uneconomical.

  Therefore, it has been proposed that the mattress be divided (see, for example, Patent Document 1).

  The split-type mattress shown in Patent Document 1 connects adjacent component mattresses via a flexible fastener (coupling means). The split mattress consists of two first mattresses (for head and legs) sewn with a tape member with a free fastener, and one second mattress (for waist) with sewn free fasteners. As shown, the first mattress and the second mattress are the same size, but do not have the same configuration. Therefore, when the second quilt for the lower back is worn out due to wear, the first quilt for the head or leg cannot be diverted, and it is necessary to prepare a second quilt separately. In addition, the existing universal fastener (coupling means) is obstructive in the connecting direction connected by the universal fastener (coupling means), that is, in the short side direction orthogonal to the long side direction in which the universal fastener (coupling means) extends. Thus, since another universal fastener (joining means) cannot be provided, the adjacent component mattress is in an unconnected floating state. Therefore, the split-type mattress shown in Patent Document 1 has a limitation in the joining direction, and can connect only one direction of the long side direction or the short side direction.

JP 2002-159372 A

  Therefore, the technical problem to be solved by the present invention is to provide a split rug that can be flexibly adapted to various sizes depending on the intended use without any limitation on the component bodies to be joined and the joining direction. is there.

Means for solving the problems and their actions and effects

  In order to solve the above-described technical problem, the split-type rug according to the present invention has the following features.

That is, the split rug according to the present invention is
A plurality of vertical engagement members are arranged in the same manner on the opposite vertical side edges of the bottom surface of the rectangular component body, and on the opposite lateral side edges of the bottom surface of the component body, A plurality of lateral engagement members are arranged in the same manner,
A longitudinal engagement member or a lateral engagement member of a component body is opposed to a corresponding longitudinal engagement member or a lateral engagement member of another adjacent component body;
A corresponding component body and another adjacent component body are integrated by the corresponding vertical engagement members or horizontal engagement members engaging each other.

  According to the split type rug having the above-described configuration, the corresponding vertical engagement members or the horizontal engagement members are engaged with each other, so that one component body and another adjacent component body are integrated. Therefore, there is no restriction on the component bodies to be joined and the joining direction, and the component bodies can be freely connected in the vertical direction and / or the horizontal direction, so that various sizes can be flexibly supported depending on the usage. Possible split rugs can be formed.

  Engagement between corresponding vertical engagement members or horizontal engagement members is performed via a connecting member.

  The connecting member can be a string that does not have rigidity and can be deformed flexibly. However, when tensile stress is applied, the tensile stress acts non-uniformly on the engaging member. Transforms into Therefore, it is preferable that the rod has rigidity so that uniform stress acts on the engaging member.

  Various types of engaging members can be used, but both ends of the band are overlapped while bending the elastic band in a loop shape, and both ends are connected to the bottom surface of the component body. An insertion hole is formed between the loop-shaped belts.

  It is preferable that the elastic band is a rubber for shoe upper that has appropriate elasticity and stretchability and can stably and easily fix sewing, adhesion, and the like. .

  A plurality of component bodies can be connected in a row, or a plurality of component bodies can be connected in a matrix. When component bodies are connected in a matrix, a plurality of component bodies are connected vertically and horizontally by engaging vertical engaging members of opposing component bodies and horizontal engaging members of opposing component bodies, respectively. .

  The engaging member may be a hook in addition to the loop-shaped band having elasticity as described above.

  Below, the split-type rug 30 which concerns on one Embodiment of this invention is demonstrated in detail, referring FIG.

  As shown schematically in FIG. 2 (A), the split-type rug 30 has three component bodies 10 denoted by reference signs A to C connected in a horizontal row, and has a long side of about 200 cm and a short side of about 100 cm. Or, as schematically shown in FIG. 2 (B), six component bodies 10 of reference signs A to F are connected in a matrix (3 rows in the horizontal direction × 2 rows in the vertical direction), and the long side is about 200 cm. The short side is about 200 cm, and a plurality of component bodies 10 are combined and integrated.

  As shown in FIG. 1, each component body 10 constituting such a split rug 30 has, for example, a rectangular shape with a long side of about 100 cm and a short side of about 66 cm and a length-to-width ratio of 3: 2. is doing. The component body 10 may have a rectangular shape with other dimensions or a square shape. A cushion material, cotton, wool, or the like is accommodated in the cloth cover 12 of the component body 10 to provide desired cushioning properties (elasticity and flexibility).

  At the side edge of the bottom surface 16 of the cover 12, a plurality of engagement band members 18 are fixed by sewing or bonding. When the component body 10 is viewed from the upper surface 14, the plurality of engagement band bodies 18 partially protrude from the side edges of the bottom surface 16. Five engagement band bodies (lateral engagement members) 18 are provided apart from each other on the upper and lower long side edges. Four engagement band bodies (vertical engagement members) 18 are provided apart from each other on the left and right short side edges. When the component bodies 10 are combined, the five engagement band bodies (lateral engagement members) 18 of a certain component body 10 correspond to the corresponding five engagement band bodies (lateral engagement members) 18 of the other component body 10. The four engagement band bodies (vertical engagement members) 18 of one component body 10 face the corresponding four engagement band bodies (vertical engagement members) 18 of the other component body 10. .

  The engagement band 18 has moderate elasticity and stretchability, and can stably and easily adhere to the side edge of the cover 12 such as sewing and adhesion, and the shoe upper rubber. It is composed of For example, the engaging band 18 is 15 mm in width and 35 mm in length while the rubber band for the upper of the shoe is curved in a loop shape, and the both ends of the band are overlapped, and the both ends are connected to the component body. Bonded to the bottom. The portion curved in a loop shape protrudes from the side edge of the bottom surface 16 of the cover 12 by approximately 15 to 20 mm. An insertion hole 20 is formed between the loop-shaped engagement band members 18. The hole diameter of the insertion hole 20 is approximately 5 to 6 mm.

  In the case of the three mouths shown in FIG. 2 (A), the three component bodies 1 are aligned and arranged face down so that the long side portions thereof are in contact with each other. At this time, the component body 10 with the reference signs A and C is adjacent to the component body 10 with the reference sign B on the left and right sides, and the five engagement band bodies (the horizontal links) on the left side of the component body 10 with the reference sign B The joint member 18 is opposed to the five engagement band bodies (lateral engagement members) 18 on the right side of the component body 10 denoted by reference symbol A, and the five engagement band members (right side of the component body 10 denoted by reference character B) ( (Lateral engagement members) 18 are opposed to the five engagement band bodies (lateral engagement members) 18 on the left side of the component body 10 denoted by reference symbol C.

  As shown in FIG. 3A, the engagement band (lateral engagement member) 18 fixed to the side edge of the cover 12 can be elastically deformed. The combined body (lateral engagement member) 18 is bent in directions opposite to each other. Therefore, the insertion holes 20 of the engagement band bodies (lateral engagement members) 18 that are opposed to and in contact with each other are aligned and arranged in a communication state. Then, as shown in FIG. 3 (B), a rigid elongated connecting rod (connecting member) 26 is inserted into a group of insertion holes 20 in a communication state, and adjacent component bodies 10 are connected to each other. As a result, a split rug 30 in which a plurality of component bodies 10 are integrated is produced.

  The engagement between the opposing and abutting lateral engagement members or vertical engagement members can be replaced by a connecting member such as a string or rope that is flexible and deforms flexibly, but tensile stress has acted on it. Sometimes, the tensile stress acts non-uniformly on the engaging member 18, so that the component body 1 is deformed in a mountain shape. Therefore, the elongated connecting rod 26 having rigidity is preferable so that uniform stress acts on the engaging member 18. The elongated elongated connecting rod 26 is made of various materials such as wood, bamboo, acrylic, and steel, and has a diameter of approximately 5 to 6 mm.

  As shown in FIG. 3B, after the connecting rod (connecting member) 26 is inserted into the group of insertion holes 20, the retaining portion 28 having a diameter larger than the diameter of the insertion hole 20 is connected to the connecting rod 26. It is attached to both ends. Or what processed the both ends of the connecting rod (connecting member) 26 into the retaining part which has the inclined surface which spreads toward the end part can be used. In either case, the connecting rod (connecting member) 26 inserted through the insertion hole 20 is difficult to be removed from the insertion hole 20. Therefore, the split-type rug 30 of the present invention has no limitation on the component body 10 to be joined and the joining direction by inserting the connecting rod (connecting member) 26 into the group of insertion holes 20, and the longitudinal and / or lateral direction. Since the component bodies 10 can be freely connected in the direction, it is possible to flexibly cope with various sizes according to the usage.

  Next, a modified example of a method of engaging (connecting) corresponding vertical engagement members or horizontal engagement members will be described with reference to FIG.

  FIG. 4A shows an example in which the connecting rod 26 is used as the connecting member as in the above-described embodiment, but the retaining portions 28 are not provided at both ends of the connecting rod 26.

  4B shows an example in which the base portion of the hook member 24 is fixed to the side edge portion of the cover 12 by sewing, adhesion, or the like. Since the engagement members are engaged (connected) using the same hook member 24, the degree of freedom of engagement (connection) is high, and an engagement band (engagement member) and a connection member become unnecessary. Contributes to cost reduction.

  FIG. 4C shows an example in which the U-shaped connecting ring 25 is inserted into each insertion hole 20 in a state where the opposing engagement belt bodies (engagement members) 18 are abutted with each other. Since it is not necessary for the engagement band (engagement member) 18 to bend in the opposite direction, the engagement band (engagement member) is shortened by shortening the base portion of the loop-shaped engagement band (engagement member). ) Can be shortened to prevent the adjacent component bodies 1 from being separated from each other.

  In the above-described embodiment, three component bodies 1 having a long side of about 100 cm and a short side of about 66 cm are used in order to create a split rug 30 having a long side of about 200 cm and a short side of about 100 cm. is doing. The reason why the three-fold type rug is used is that the entrance is generally about 90 cm or the rug is customarily folded in three. However, if it is not caught by such an event, it is also possible to use a two-part rug. In this case, the split rug 30 having a long side of about 200 cm and a short side of about 100 cm can be created by using two square component bodies 1 each having a side of about 100 cm.
