The present invention relates to a net chair including a net binding member used for fixing a net in contact with a body and a net chair including the same.

In general, a net chair has a backrest and a seat by fixing a net to a wooden or steel frame. Compared to chairs made of fabric or leather, it has the advantage of being cooler than chairs made of fabric or leather because it supports the back and buttocks, which sweat in summer, with a net.

The durability of a hammock is mainly determined by the connection between the net and the frame. The mesh itself, which is mainly woven with synthetic resin, has good rigidity, but in the part connected to the frame, the flexible mesh moves during use, causing friction and causing the mesh to break.

Republic of Korea Utility Model Registration No. 20-0489363, which was previously devised by the present applicant, has the advantage of being able to easily and firmly fix the net, which is advantageous in improving productivity, but the edge of the net wrapped around the pole is exposed as it is to the outside, There was a disadvantage in that it was frequently rubbed against the user's buttocks and wear was rapidly progressing.

In addition, the assembly is performed by inserting the net-wound jolt into the frame and fixing it with a tack needle, etc., and the work of inserting the jolt is very laborious because the groove into which the jolt is inserted is formed narrowly to prevent separation.

1 and 2 relate to a mesh binding member according to an embodiment of the present invention.

The mesh binding member 100 according to an embodiment of the present invention includes a mesh 10, a strap 20, a fastening part 30 and a frame 40.

The mesh 10 is to form a surface on which the body leans, and may be a cloth or net with elasticity.

Joltae 20 is a member on which the net 10 is wound, and is made of a material that is easy to bend. When the net wrapped around it is pulled strongly, the cross-sectional area can be slightly changed, and the long fabricated one is cut to an appropriate length and used.

The frame 40 includes a base portion 41 , a side wall portion 42 and a double wall portion 43 . These may be integrally manufactured by injection molding, and at this time, by using a synthetic resin, they may be configured to be elastically deformed to some extent.

The base portion 41 forms the bottom surface of the mesh binding member, and may further include various structures for coupling with the frame of the chair.

The side wall portion 42 is a portion erected upward along the circumference of the base portion 41 and forms a wall surface. As a result, the frame 40 is hollow inside and has a shape like a box or basket that is open to the top.

The double wall portion 43 forms a double wall surface along the outer circumference of the side wall portion 42, and is connected to the outside from the middle height of the side wall portion 42 and then parallel to the outer wall of the side wall portion 42 to the upper end of the side wall portion. it is formed Between the outer wall surface of the side wall portion 42 and the inner surface of the double wall portion 43, a mounting groove 44 open upward is formed. The mounting groove 44 is a narrow and deep groove, and is formed along the upper circumference of the frame 40 .

The height at which the side wall portion 42 and the double wall portion 43 protrude upward may vary in various embodiments.

At the lower end of the double wall part 43 starting to run sideways from the side wall part 42, the lower end of the fastening part 30 inserted into the mounting groove 44, that is, the tacker hole exposing the body 31 to the outside ( 45) is formed. At this time, a plurality of tacker holes 45 are formed at regular intervals along the longitudinal direction of the double wall portion 43 .

The fastening part 30 is a component coupled to the mounting groove 44 of the frame 40 after being fastened with the strap 20 winding the net 10, which connects the net 10 and the frame 40. is an intermediate member.

The fastening part 30 can be used by cutting or bending the long injection to the required length, similarly to the strap 20. These fasteners may be made of urethane, elastomer or EVA material.

When viewed in cross section, the fastening part 30 can be subdivided into a body 31 part and a cover 32 part.

The body 31 is a part fixed into the mounting groove 44 of the frame 40. In addition, the body 31 is formed with a fitting groove 311 in which the net 10 is wound around the pole 20 is accommodated.

The cover 32 is a part extending horizontally from the upper part of the body 31, and covers and covers the net 10 exposed to the upper part by being wound around the strap 20. The cover 32 extends horizontally at least as much as the width of the strap 20 to cover and cover the net 10 wound on the strap 20.

In the illustrated embodiment, the cover 32 is formed to be longer than the width of the strap 20, so that even when the net 10 is elastically deformed by the weight of the user, the cover 32 is wound around the strap 20. It can completely cover the area.

In this way, since the cover 32 covers and hides the mesh wound around the straw, the user's clothes or the like do not sweep the wound around the straw while being hit by a chair.

Fitting groove 311 for accommodating the joltae 20 is provided in a recessed shape on one side of the body 31.

Corresponding to the roughly square cross-section of the strap 20, the fitting groove 311 is rectangular in cross section so that the inner surface of the fitting groove 311 interviews the top 21, one side 22 and the bottom 23 of the strap 20 is formed by In particular, the ceiling surface of the fitting groove 311 in contact with the upper part 21 of the joltae 20 may be the bottom surface 321 of the cover 32.

When the net 10 is pulled, the upper part 21 of the strap 20 is also elastically deformed and pressed down to deform. At this time, a gap may be formed between the bottom surface 321 of the cover 32 and the net 10 . When the pulling of the mesh 10 disappears, while the shape of the strap 20 is restored, the mesh 10 is re-bited by the top of the strap 20 and the bottom surface 321 of the cover 32.

This reduces the abrasion of the mesh on the area where the net is wound during use of the net chair where the net is repeatedly pulled.

On the other hand, the lower end of the body 31 and the bottom surface of the mounting groove 44 are formed with a fastening groove 312 and a fastening hole 46 to which a fixing screw is fastened.

3 to 6 sequentially show the coupling relationship between the net 10, the strap 20, the fastening part 30 and the frame 40.

Figure 3 shows the assembled state of the soldae 20 and the net (10). In a state in which the net 10 is padded around the circumference of the zoltae 20, the net 10 and the zoltae 20 are stitched together (N) and are firmly fixed to each other.

At this time, the netting 10 is arranged so as to be padded on both the left and right sides of the joltae where the stitching (N) is performed, so that the netting 10 is fixed on both the left and right sides of the joltae 20 by one stitching.

In this way, the mesh 10 and the strap 20 are stitched (N), and the primary fixation between them is made.

Figure 4 is related to the coupling of the fastening part and the net-coupled joldae (hereinafter referred to as 'joldae' by shortening 'net-coupled joldae').

By pressing the strap 20 into the fitting groove 311, the fastening portion 30 and the strap 20 may be coupled. Since both the top and bottom of the strap 20 are bitten on the inner wall of the fitting groove 311, the strap does not come off arbitrarily in the fitting groove 311.

On the other hand, referring to another embodiment shown in FIG. 7, a concave recessed groove 311a is formed on the lower inner surface of the fitting groove 311, and a protrusion 24 corresponding to the recessed groove is provided at the bottom of the strap 20. has been That is, the fitting groove 311 is formed with a larger inner area than the inlet side, and the strap 20 is manufactured with a cross section corresponding to this, so that the strap 20 entering the fitting groove 311 is more difficult to fall out. .

Referring back to FIG. 4, after inserting the strap 20 into the fitting groove 311, the body 31 and the strap 20 of the fastening part 30 are stitched together (N) or a mesh by tacking needles (not shown). (10), the pole 20 and the fastening part 30 are secondaryly fixed.

This secondary fixation prevents the joltae 20 entering the fitting groove 311 from being separated by external force, and then the fastening part 30 is somewhat rough during the work of mounting the fastening part 30 to the frame 40. Even if handled, it is important to prevent the joltae 20 from falling out of the fitting groove 311.

5 and 6 relate to the assembly process of the fastening part 30 and the frame 40.

Since the frame 40 must withstand the tension of the net 10 supporting the user's body, it is made of a material that is relatively robust compared to the fastening part 30 and the like. Accordingly, the width of the mounting groove 44 is not easily widened, so it is necessary to press with considerable force in order to insert the body 31 of the fastening part 30 into the mounting groove 44.

This causes the operator to get tired easily, and also causes assembly defects in which the fastening part is not completely inserted into the mounting groove.

After mounting the fixing screw (S) in the fastening hole 46 formed at the bottom of the mounting groove 44, inserting a part of the body 31 of the fastening part 30 into the mounting groove 44, the body 31 The fastening groove 312 formed on the lower surface of the presses enough to enter the front end of the fixing screw (S).

Then, when the fastening part 30 is pressed while turning the fastening screw S, a screw thread is formed in the fastening groove 312, and the body 31 goes deep into the mounting groove 44 by the fastening screw S. By using several more fixing screws along the longitudinal direction of the mounting groove, it is possible to eliminate the inconvenience of the operator having to press the fastening part into the mounting groove all the way.

Referring to FIG. 6, after the fastening part 30 is completely inserted to the bottom of the mounting groove 44, the tacker needle T is shot through the tacker hole 45, and the tacker needle T is the body 31 It can be penetrated and driven up to the side wall portion 42. A plurality of tacker needles are driven along the circumference of the mounting groove, so that the fastening part 30 is more completely secondaryly fixed to the frame 40.

Furthermore, as shown, the tacker needle T may penetrate the body 31, the strap 20, the net 10, and the side wall portion 42 of the fastening part 30, and bind them firmly to each other.

8 is a mesh chair according to an embodiment of the present invention.

The mesh chair 200 according to an embodiment of the present invention is a seat plate 220 or a backrest ( 230) is used. In the illustrated embodiment, the seat 220 and the backrest 230 are made of the mesh binding member 100, a strap, a mesh, and a cover.

Although not shown, in another embodiment, the mesh binding member may be used only for the seat or the backrest. In addition, seat plates, backrests, and headrests may be provided according to various types of chairs, and a mesh binding member may be used for one of them.
