Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for manufacturing cushion furniture.

[0002]

2. Description of the Related Art Conventional cushion furniture, such as cushions, low sofas, and chairs, is manufactured by roughly crushing recycled urethane (broken material) into a bag-like outer skin. there were. As another conventional manufacturing method, the breaking material is molded together with an adhesive by a mold and a press, and then the outer cover is covered to perform buttoning.

[0003]

However, in the method of blowing the broken material into the outer skin, the entire volume is reduced or the normal outer shape cannot be maintained while using the cushion furniture. However, there was a drawback of being deformed. Further, in the method using the mold, it is necessary to take time and labor to perform post-treatments such as covering the outer skin and stopping the button.

Therefore, an object of the present invention is to provide a method for producing cushion furniture which does not lose its overall shape and its volume does not decrease even after long-term use. Another object is to provide a method for manufacturing cushion furniture that does not require post-treatment after molding. Another object of the present invention is to provide a method for manufacturing cushion furniture that can fix the skeletal member to the outer skin. Another object of the present invention is to provide a method for manufacturing cushioning furniture, which can reduce or eliminate the unevenness of the broken material and smoothly improve the feel of the outer surface.

[0005]

In order to achieve the above-mentioned object, a method for manufacturing cushion furniture according to the present invention is to prepare a bag-like shape after stirring a foam synthetic resin breaking material and an adhesive. This is a method of blowing into the produced outer skin and solidifying.

[0006] Further, there is a method in which a skeleton member is previously built in a bag-shaped outer skin, and then a material obtained by stirring a foam synthetic resin breaking material and an adhesive is blown into the outer skin to solidify.

In addition, the front skin and the back skin of the bag-shaped outer skin are partially sewn together in advance, and then a material of foam synthetic resin and an adhesive are stirred, and the mixture is put into the outer skin. Blow into
This is a method of solidifying.

In addition, a skeletal member is previously built in the bag-shaped outer skin, and the outer skin is partially connected to the skeletal member, and thereafter, a foam synthetic resin breaking material and an adhesive are This is a method in which the stirred material is blown into the outer skin to solidify. Further, it is a method of laminating a foam synthetic resin sheet for cushioning unevenness on the inner surface of the front skin of the outer skin, and then performing the blowing.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the drawings showing the embodiments.

A first embodiment of a method for manufacturing cushion furniture will be described. FIG. 1 shows cushion furniture 1 comprising a cushion. The cushion furniture 1 has, as shown in FIG. 2, a foam synthetic resin breaking material 2 ... And an adhesive 3 inside. The breaking material 2 is made of recycled urethane, polyethylene, or the like. The adhesive 3 is made of urethane polymer and methylene chloride, for example.

To manufacture the cushion furniture 1,
First, as shown in FIG. 3, the broken material 2 of the foamed synthetic resin and the adhesive 3 are stirred by the stirrer 4. At this time, the adhesive 3 is injected into the stirrer 4 from the tank 5 by the pump 6, and air is sent to the stirrer 4 by the blower 7. After that, the blower 11 and the blow pipe are put into the outer skin 8 which is made in a bag shape in advance.
At 20 together with the air, blow the crushed material 2 ... and the adhesive 3 after stirring. In this way, after the agitated breaking material 2 ... And the adhesive 3 are blown into the outer skin 8, the blow-in port 14 of the cushion furniture 1 is closed by sewing or a fastener. After that, it solidifies over time.

A second embodiment will be described with reference to FIGS. The cushion furniture 1 comprises a low sofa (chair). First, as shown in FIGS. 4 and 5, the skeleton member 12 is previously built in the bag-shaped outer skin 8. Skeleton member 12
Consists of, for example, an iron frame or a ratchet. Thereafter, as shown in FIG. 6, a mixture of the foamed synthetic resin breaking material 2 and the adhesive 3 is blown into the outer cover 8 and then removed from the blow-in pipe 20 to be solidified.

A third embodiment will be described with reference to FIGS. 7 and 8. The cushion furniture 1 comprises a cushion.
First, the front skin 9 and the back skin 10 of the bag-shaped outer skin 8 are partially pre-sewn and connected together H at the center of the plan view. After that, a material obtained by stirring the foamed synthetic resin breaking material 2 ...
Remove from. Then, it is solidified.

A fourth embodiment will be described with reference to FIGS. 9 and 10. The cushion furniture 1 comprises a low sofa. The skeleton member 12 is previously built in the bag-shaped outer skin 8, and the outer skin 8 is partially connected to the skeleton member 12. Specifically, the front skin 9 and the back skin 10 of the outer skin 8 are sewn S near the skeleton member 12. The position of the skeleton member 12 can be fixed with respect to the outer skin 8. Then, the foamed synthetic resin crushed material 2 and the adhesive 3 are stirred and blown into the outer skin 8 to be solidified.

A fifth embodiment will be described with reference to FIG. The cushion furniture 1 comprises a cushion. First, a foam synthetic resin sheet body 13 for cushioning unevenness is laminated on the inner surface 9a of the front skin 9 of the outer skin 8. After that, the foamed synthetic resin breaking material 2 ...
Blow in and solidify. The foamed synthetic resin sheet body 13 reduces or eliminates the unevenness feeling of the fractured materials 2 ..., and the outer surface feeling is smoothly improved.

The present invention can be modified in design,
For example, the cushion furniture 1 may be a couch sofa, a bed mat, or the like. Further, the front skin 9 and the back skin 10 of the outer skin 8 may be sewn and connected H at a plurality of portions in advance in advance.

[0017]

Since the present invention is constructed as described above,
The following effects are achieved.

It is possible to manufacture the cushion furniture 1 which does not lose its overall shape and whose volume does not decrease even after long-term use (according to claims 1, 2, 3, 4, and 5). Also,
No post-treatment after molding is required.

The position of the skeleton member 12 can be fixed with respect to the outer cover 8 (according to claim 4).

(According to claim 5) The unevenness feeling of the fractured materials 2 ... Is reduced or eliminated, and the feel of the outer surface is smoothly improved.
