The frame 70 may be attached to the cushioning material 54 by an adhesive. That is, the frame 70 and the cushioning material 54 may be adhered to each other by an adhesive.

The frame 70 may be composed of a plurality of flat plate materials, but more preferably, a plurality of pipe members 72 to be described later. And, the frame 70 is preferably disposed in the inner lower portion of the seat 50, as shown enlarged for the cushion of the seat 50, the seat 50 when configured as the tube member 72 as described above It is most preferable to be arranged along the border of.

The folding member 80 is installed in the frame 70 as shown in enlarged form to form the same as the frame 70. That is, the folding member 80 is installed on a portion of the frame 70 as shown in enlarged form to form a portion of the frame 70. Thus, the folding member 80 is embedded in the seat 50 together with the frame 70.

2, the frame 70 according to an embodiment of the present invention is composed of a plurality of pipe member 72 as shown. Such a plurality of pipe member 72 is divided as shown to form a square so that the ends are arranged along the edge of the sheet 50 while being connected to each other by the folding member (80). That is, the frame 70 is divided and forms a form that can be disposed on the edge of the sheet 50 while being integrally connected by the folding member 80. Therefore, the frame 70 is embedded in the sheet 50 to support the edge of the sheet 50.

Of course, the plurality of pipe member 72 is formed in the form corresponding to the shape of the sheet 50 while being connected by the folding member 80, when the sheet 50 is formed in the shape of a circle or a triangle, unlike shown do. That is, the frame 70 is formed in a shape corresponding to the shape of the sheet 50.

The folding member 80 is mounted in the same body at the ends of the pipe members 72 facing each other as shown in an enlarged view (partly cut perspective) by welding or bolting. That is, the folding member 80 is mounted in the same body at the end of the divided frame 70. At this time, the folding member 80 is mounted to the end of the pipe member 72 which is spaced apart from each other and parallel to each other as shown in the pair form a pair.

The folding member 80 according to the embodiment of the present invention is mounted in three places while making a pair of pairs along the longitudinal direction of the frame 70 so that the frame 70 is folded in three stages. That is, the folding member 80 according to the embodiment is composed of three sets as shown. The number of the folding member 80 is determined by the folding step of the frame 70. That is, the folding member 80 is composed of one set when the frame 70 is folded in one stage, and is composed of four sets when the frame 70 is folded in four stages.

The folding member 80 is configured in a male and female form as shown in enlarged form, and is coupled to each other to connect the ends of the tube members 72. That is, the folding member 80 formed in the female and male shape is integrally connected to the pipe members 72 of the divided frame 70 while being coupled to each other. At this time, the female folding member 80 is mounted to any one of the tube member 72 of the tube member 72 facing each other as shown in the enlarged view. And, the male folding member 80 is mounted to the other tube 72 as shown enlarged.

In this way, the folding members 80 formed in the female and male shapes are connected to each other by the hinge H as shown enlarged. Thus, the folding member 80 is bent around the hinge (H) to provide a folding function to the tube member (72). That is, the pipe members 72 connected by the folding member 80 may be folded around the ends facing each other, as shown in an enlarged manner by the folding member 80. That is, the frame 70 may be partially jointed by the folding member 80.

On the other hand, the mat according to an embodiment of the present invention, it may be configured to further include a support member installed on the tube member 72 of the frame 70 to support the inner portion of the sheet 50. That is, the pipe member 72 of the frame 70 supports the edge of the sheet 50, and the support member supports the inside of the edge of the sheet 50.

The support member may be configured, for example, as a crossbar 74 that intersects between the pipe members 72 disposed at both edges of the sheet 50 as shown. As shown in the crossbar 74, both ends are respectively connected (welded or bolted) to the outer circumferential surface of the pipe member 72 disposed at both edges of the sheet 50 as shown. Therefore, the crossbar 74 supports the inside of the edge of the sheet 50 while connecting the pipe members 72 disposed on both edges of the sheet 50.

Alternatively, the support member may be configured as, for example, a circular cross band 76 that is wound around the tube members 72 disposed at both edges of the sheet 50. The cross band 76 may be formed of a rubber material, a plastic material, or a synthetic resin material, and is preferably formed in a circular band or string form as shown.
Of course, the support member may be configured to include both the crossbar 74 and the cross band 76 described above. In addition, the support member, together with the crossbar 74 and the crossband 76, is connected at right angles between the crossbars 74 as shown to form a substantially lattice shape with the crossbars 74, while the crossbands 76 It may also be configured to include; orthogonal stick (74a) for supporting the inner side of the edge of the sheet 50 with). That is, the support member is a crossbar 74; Crossband 76 and; Orthogonal stick 74a; may be configured to include.
Here, the orthogonal sticks 74a described above are attached by welding or bolting between the plurality of crossbars 74 spaced apart from each other as shown. Thus, the orthogonal stick 74a is perpendicular to the crossbar 74.

Referring to FIG. 3, the folding member 80 may include, for example, a motion bracket 81 as shown; Latch wheel 83; Disc cam 85; Hinge H; Click 87; A holding pin (P) and; Torsion spring 89; can be configured to include. That is, the folding member 80 is a latch to which the click 87 is selectively caught by the latch wheel 83. Here, the components of the folding member 80 composed of such a latch in more detail as follows.

The motion bracket 81 is mounted to the end of any one of the tube members 72 whose ends are connected to each other as shown. Motion bracket 81 is composed of a pair as shown is mounted on the end of the tube member 72 spaced apart. Therefore, the pair of motion brackets 81 have a female characteristic as they are spaced apart from each other.

The latch wheel 83 has a space SP in the middle as shown, and has a barb tooth 83a formed in one direction on one side of the outer circumferential surface. And, the latch wheel 83 has a side projection (83b) is formed as a portion is bent sideways as shown.

As illustrated, the latch wheel 83 is mounted on the other tube 72 connected to the tube 72 on which the motion bracket 81 is mounted. At this time, the latch wheel 83 is mounted to the end of the tube (72) as shown. The latch wheel 83 is inserted between the pair of motion brackets 81 as shown. Accordingly, the latch wheel 83 has a male characteristic. That is, the motion bracket 81 is female and the latch wheel 83 is male.

The disc cam 85 is inserted in the middle of the latch wheel 83 through the space SP of the latch wheel 83 as shown. The disc cam 85 is inserted between the pair of motion brackets 81 together with the latch wheel 83. That is, the disc cam 85 and the latch wheel 83 are inserted together in the motion bracket 82. As shown, the disc cam 85 has a fan-shaped form in which the radius R of one side is larger than the radius r of the other side to form an eccentricity. As the disc cam 85 has one side and the other radius (R, r) different from each other, as shown, the engaging projection (85a) is formed on one side. That is, the disc cam 85 is divided into one side and the other side around the locking protrusion 85a.

The hinge H penetrates the side of the motion bracket 81 as shown. Accordingly, the hinge H sequentially passes through the latch wheel 83 and the disc cam 85 inserted into the motion bracket 81. Thus, the hinge H rotatably fixes the latch wheel 83 and the disc cap 85 to the motion bracket 81.

The click 87 is formed in the shape of a fork as shown. The click 87 is inserted into the pair of motion brackets 81 and rotatably fixed to the motion brackets 81 through fixing pins P to be described later.

The fixing pin P penetrates the motion bracket 81 to fix the click 87 inserted into the motion bracket 81 inside the motion bracket 81. At this time, the fixing pin (P) is fixed to the click 87 in a state in which the torsion spring (89) to be described later is wound.

As shown in the torsion spring 89, one end forms a straight line, and the other end forms a horizontal line at a substantially right angle with one end. The torsion spring 89 overlaps the side of the click 87 and is inserted into the motion bracket 81 together with the click 87. The torsion spring 89 is fixed to the motion bracket 81 by the fixing pin P together with the click 87.

Referring to FIG. 4, the torsion spring 89 of the folding member 80 has one straight line supported by the pipe member 72 of the frame 70 as shown in the figure, and the other horizontal end thereof is the outside of the click 87. Is supported. Therefore, the torsion spring 89 elastically supports the click 87 through the other end in a state where one end thereof is supported by the tube member 72.

The pipe members 72 connected to each other by the folding member 80 may be horizontally formed or folded at various angles about the folding member 80 as illustrated. At this time, the folding member 80 folds the tube 72 by the operation of the disc cam 85 and the click 87.

Referring to FIG. 5, as described above, the seat 50 may be varied in various forms as the frame is folded at various angles by the folding member.

Referring to Figures 4 and 5 attached to the operation of the shape-variable mat according to an embodiment of the present invention configured as described above are as follows.

Referring to FIG. 4, the tube member 72 of the frame 70 is horizontally folded or folded as shown by an external force. At this time, the disc cam 85 of the folding member 80 rotates around the hinge (H). Therefore, the click 87 of the folding member 80 is selectively engaged with the barb teeth 83a of the latch wheel 83 while being caught by the end of the locking protrusion 85a of the disc cam 85, or of the locking protrusion 85a. It is separated from the barb 83a by rotation.

In more detail about this, when the click member (72) is folded in the direction (a) of the drawing, as shown in the state caught on one end of the engaging projection (85a) formed on the disc cam 85 It engages with the barb 83a of the latch wheel 83. In addition, the click 87 is engaged at another position of the barb 83a while pivoting about the hinge H by the tube 72 when the tube 72 continues to be folded in the direction (a). At this time, the click 87 is engaged with the barb tooth 82a while making a "pushing" sound by the elastic force of the torsion spring 89.

This click 87 is released from the barb 83a by the disc cam 85 when the tube 72 is completely folded in the direction (a) as shown by the broken line. At this time, the disc cam 85 is rotated by the tube member 72, the other end of the locking projection (85a) is caught by the side projection (83b) of the latch wheel (83). Accordingly, the click 87 slides back by the pipe member 72 that is folded while being uniaxially rotated and slides the outer circumferential surface of the locking protrusion 85a. That is, the click 87 is folded back to contact the outer peripheral surface of the locking projection (85a). Thus, the click 87 leans back and leaves the barb 83a.

On the contrary, when the tube member 72 is folded in the direction (b) of the drawing and is unfolded in a horizontal state as shown by the broken line, the disc cam 85 rotates about the hinge H as shown by the broken line. As a result, the click 87 is held back while being in contact with the outer circumferential surface of the locking protrusion 85a. Therefore, the click 87 does not engage the barb 83a of the latch wheel 83 until the tube 72 is fully folded. Then, the click 87 is again engaged with the barb 83a as described above when the tube member 72 moves in the direction (a) again.

In this way, as the click 87 engages the barb 83a, the tube member 72 can maintain the folded angle. And, as the click 87 is separated from the barb 83a by the disc cam 85, the tube member 72 can maintain a horizontal state.

Referring to Figure 5, the sheet 50 is changed in shape in various forms as shown, as the pipe member is folded as described above by the folding member. At this time, the sheet 50 maintains a variable shape as it is supported by the tube. Therefore, the user can fold the sheet 50 in a desired form.

On the other hand, Figure 6 is a perspective view of a mat according to another embodiment of the present invention, Figure 7 is a side view showing a state of use of the mat shown in FIG. Referring to the mat (M) according to another embodiment as follows with reference to the accompanying drawings, the mat (M) according to another embodiment is the same as the mat shown in Figures 1 to 5 all the configuration described above However, the difference is that the auxiliary cushion 56 is mounted on the seat 50. Therefore, only these differences are explained as follows.

Referring to FIG. 6, the seat 50 may be provided with an auxiliary cushion 56 as shown on the surface on which the user is seated. The auxiliary cushion 56 may be configured as a cover 56a in which the cushioning material 56b is embedded, as shown in an enlarged manner. The auxiliary cushion 56 is preferably configured separately from the sheet 50 and attached to the sheet 50 in the same manner through sewing or bonding. The auxiliary cushion 56 reinforces the cushion of the seat 50. Therefore, the auxiliary cushion 56 is preferably attached when improving the cushion of the seat 50.

As shown in the figure, the auxiliary cushion 56 may be configured in plural numbers, but unlike the illustrated example, one or two to three small amounts may be provided. Thus, when the auxiliary cushion 56 is configured in a small amount, the auxiliary cushion 56 is preferably installed at the end and the middle portion of the seat 50 to support the head and waist of the user.

Referring to FIG. 7, the mat M according to another embodiment is varied in various forms while bending a portion like the mat M shown in FIGS. 1 to 5 even when the auxiliary cushion 56 is installed. Therefore, the user can vary the mat (M) to the desired shape.

Shape-deformable mat according to the present invention as described above, by providing a folding function while connecting the frames divided by the folding member there is an effect that the shape of the sheet is conveniently deformed in various forms by folding the frame.

In particular, since the seat is folded by a frame that can be folded, it can be used as a bed by folding the seat or folding the seat, and can be used as a seated sofa. It has an effect.

In addition, since the folding member is formed of a latch, the frame can be folded at various angles.

In addition, since the frame is formed in a rectangular shape by the pipe-shaped pipe material, not only can reduce the manufacturing cost of the frame, but also has the effect of supporting the edge of the seat for cushioning the seat.

In addition, when installing the support member consisting of crossbars or crossbands on the pipe member of the frame, there is an effect that can improve the bearing capacity of the frame while minimizing the additional cost required for the manufacture of the frame.

In particular, when the support member is composed of a cross band, there is an effect that the manufacturing process can be simplified because the cross band is wound on the tube member of the frame.

In addition, there is an effect that can further strengthen the cushion of the seat when installing the auxiliary cushion on the seat.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea. Therefore, the shape and structure of each component shown in the embodiment of the present invention can be carried out by modifying, it is natural that the modification of the shape and structure belong to the utility model registration claims of the present invention attached.
