The present invention provides a chaise long type sofa that can be easily performed. In addition, because the sofa is one of the interiors, it is possible to provide a chaise long type sofa in which the replacement connecting jig for exchanging the seat arrangement is not visible from the outside and the appearance is not impaired. is there.

  The chaise long type sofa of the present invention has left and right sleeves, two or more seats installed between them, and a backrest, and the seat and the backrest can be integrated or separable. The seat is a long seat that is longer than the standard seat and its longitudinal length and protrudes forward from the front surface of the sofa body.

  The sofa of the present invention is a chaise long type sofa having the above-described configuration, and the seat and the sleeve are connected by a seat-sleeve connector, and the seat-sleeve connector is operated from the bottom side of the seat. The seat and sleeve can be removed by removing the seat-sleeve joint from the seat, and the long seat and standard seat can be rearranged after the seat and sleeve are detached. The seat and sleeve after replacement can be connected by a seat-sleeve connector. In this case, as described in claim 2, the seat-sleeve coupling device includes a seat-side coupling portion and a sleeve-side coupling portion, and the seat-side coupling portion is attached to the bottom surface of the base wheel so as to be removable from the outside. When the connecting portion is attached to the lower portion of the sleeve frame and the seat side connecting portion is removed from the bottom surface of the seat, the seat and the sleeve can be detached.

  The sofa according to the present invention is the chaise long type sofa according to claim 3, wherein the sleeve and the backrest are connected by a sleeve-backrest connector, and the sleeve-backrest connector is operated from the front side of the backrest. It is attached to the front side of the backrest so that it can be removed and the sleeve and backrest can be detached by removing the sleeve-backrest connector from the backrest, and the sleeve and backrest are detached, and the seat and sleeve are detached The sleeve can be detached from the seat and the backrest, and the long seat and the standard seat can be rearranged after the sleeve and the seatback are detached from the seat and the backrest. The sleeve and the sleeve can be connected by a seat-sleeve connector, and the backrest and the sleeve can be connected by a sleeve-backrest connector. In this case, as described in claim 4, the sleeve-backrest coupling tool includes a sleeve-side coupling portion and a backrest-side coupling portion, and the backrest-side coupling portion is attached to the back frame front side so as to be detachable from the outside. The sleeve-side connecting portion is attached to the upper portion of the sleeve frame, and the sleeve and the backrest can be detached by removing the backrest-side connecting portion from the back frame. As described in claim 5, in the chaise long type sofa, the backrest side connecting part of the sleeve-backrest connecting tool is arranged in a place hidden behind the backrest cushion and invisible from the outside. it can.

The chaise long type sofa of the present invention has the following effects.
(1) Since the arrangement of the standard seat and the long seat can be interchanged, the standard seat and the long seat can be interchanged according to the layout of the house where the sofa is placed, the indoor layout, etc. Arrangement that does not hinder access to the veranda or the outlet is possible.
