【０００１】
【発明の属する技術分野】
本発明は、クッション家具類の製法に関する。
【０００２】
【従来の技術】
従来のクッション家具類───クッション、ローソファー、座イス等───の製法は、リサイクルウレタンを粗く粉砕したもの（破材）のみを袋状の外皮に吹込む方法があった。また、別の従来の製法としては、上記破材を接着剤とともに金型とプレスでモールドした後に、外皮を被覆して、ボタン止めを行っていた。
【０００３】
【発明が解決しようとする課題】
しかし、破材を外皮に吹込む方法では、クッション家具類を使用しているうちに、全体の体積が減少したり、あるいは、正常な外形が維持出来ずに、変形するという欠点があった。また、モールドによる方法では、外皮の被覆やボタン止め等の後処理を行うのに手間が必要とされていた。
【０００４】
そこで、本発明は、長期間使用しても、全体の形状が崩れず、体積も減少しないクッション家具類の製法を提供することを目的とする。また、成型後の後処理が不要なクッション家具類の製法を提供することを他の目的とする。また、外皮に対して骨格部材を固定することができるクッション家具類の製法を提供することを他の目的とする。また、破材の凹凸感を減少もしくは消滅させて、外面の感触をなめらかに改善することができるクッション家具類の製法を提供することを他の目的とする。
【０００５】

BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing cushion furniture.
[0002]
[Prior art]
The conventional method of manufacturing cushion furniture --- cushions, low sofas, seat chairs, etc .--------------------------------------------------------------------------------- (Refill) Crushed Recycled urethane As another conventional manufacturing method, the above-mentioned broken material is molded with a die and a press together with an adhesive, and then the outer cover is covered to perform button fastening.
[0003]
[Problems to be solved by the invention]
However, the method of blowing the broken material into the outer skin has a drawback that the whole volume is reduced while the cushion furniture is used, or the normal outer shape cannot be maintained and deformed. Further, in the method using a mold, labor is required to perform post-processing such as covering of the outer skin and buttoning.
[0004]
Therefore, an object of the present invention is to provide a method for producing cushion furniture in which the overall shape does not collapse and the volume does not decrease even when used for a long period of time. Another object of the present invention is to provide a method for producing cushion furniture that does not require post-processing after molding. It is another object of the present invention to provide a method for manufacturing cushion furniture that can fix a skeleton member to an outer skin. It is another object of the present invention to provide a method for producing cushion furniture that can smoothly improve the feel of the outer surface by reducing or eliminating the unevenness of the broken material.
[0005]
[Means for Solving the Problems]
In order to achieve the object mentioned above, manufacturing method of the cushion furniture according to the present invention, in the bag-like outer skin, a built-in pre-frame member, and, linked to partially above the frame member to the outer skin Then, the foamed synthetic resin broken material and the adhesive are stirred and blown into the outer skin without using a mold , and solidified .
Further, in the bag-shaped outer skin, a skeletal member is incorporated in advance, and a foamed synthetic resin sheet for uneven cushioning is laminated on the outer surface of the outer skin, and the outer skin is partially above This is a method of connecting to a skeletal member and then blowing and solidifying the foamed synthetic resin broken material and adhesive into the outer skin without using a mold .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
[0007]
Reference Example 1 that is closely related to the invention of the method for manufacturing cushion furniture will be described.
FIG. 1 shows cushion furniture 1 composed of cushions. The cushion furniture 1 includes a foamed synthetic resin broken material 2 and an adhesive 3 as shown in FIG. The broken material 2 is made of recycled urethane, polyethylene, or the like. The adhesive 3 is made of, for example, urethane polymer and methylene chloride.
[0008]
In order to manufacture the cushion furniture 1, first, as shown in FIG. 3, the foamed synthetic resin broken material 2 and the adhesive 3 are stirred with a stirrer 4. At this time, the adhesive 3 is injected into the stirrer 4 from the tank 5 with the pump 6, and air is sent into the stirrer 4 with the blower 7. Thereafter, the broken material 2... After stirring and the adhesive 3 are blown into the outer skin 8 made in a bag shape together with air by the blower 11 and the blowing pipe 20. In this manner, after the agitated broken material 2 and the adhesive 3 are blown into the outer skin 8, the blowing port 14 of the cushion furniture 1 is closed with sewing or a fastener. Thereafter, it solidifies over time.
[0009]
A reference example 2 will be described with reference to FIGS.
The cushion furniture 1 is composed of a low sofa (sitting chair). First, as shown in FIGS. 4 and 5, a skeleton member 12 is built in a bag-like outer skin 8 in advance. The skeleton member 12 is made of, for example, an iron frame or a ratchet. Then, as shown in FIG. 6, the foamed synthetic resin broken material 2 and the adhesive 3 are stirred and blown into the outer skin 8, and then removed from the blowing tube 20 and solidified.
[0010]
A reference example 3 will be described with reference to FIGS.
The cushion furniture 1 includes a cushion. First, the front skin 9 and the back skin 10 of the bag-like outer skin 8 are partially sewn and connected in advance at the center in plan view. After that, the foamed synthetic resin broken material 2 and the adhesive 3 are stirred, and the blow pipe 20 is inserted into the outer skin 8 to be removed from the suction pipe 20. Then, it is solidified.
[0011]
The first embodiment will be described with reference to FIGS.
The cushion furniture 1 includes a low sofa. A skeleton member 12 is built in the bag-like outer skin 8 in advance, and the outer skin 8 is partially connected to the skeleton member 12. Specifically, the outer skin 8 and the back skin 10 of the outer skin 8 are sewn S in the vicinity of the skeleton member 12. The position of the skeleton member 12 can be fixed with respect to the outer skin 8. Thereafter, the foamed synthetic resin broken material 2 and the adhesive 3 are stirred and blown into the outer skin 8 (see FIGS. 3 and 6) to be solidified. Other configurations are the same as those in Reference Examples 1 and 2.
[0012]
With reference to FIG. 11, a reference example 4 closely related to the present invention will be described.
The cushion furniture 1 includes a cushion. First, a foamed synthetic resin sheet 13 for bumps and depressions is laminated on the outer skin 8 and the inner surface 9 a of the skin 9. Thereafter, the foamed synthetic resin broken material 2 and the adhesive 3 are stirred and blown into the outer skin 8 to be solidified. The foamed synthetic resin sheet 13 reduces or eliminates the unevenness of the broken material 2 to smoothly improve the outer surface feel.
[0013]
Next, a second embodiment will be described. That is, the foamed synthetic resin sheet 13 for bumps and depressions is laminated on the outer surface 8 of the outer skin 8 and the inner surface 9a of the skin 9 , and then blown. Other configurations are the same as those of the first embodiment.
[0014]
