Benefits of technology

"The invention is a sofa with a unique base structure that includes padding elements, frames, and a kinematic mechanism that allows the frames to shift and stop in desired positions. The base structure also includes two identical elements, called \"small legs,\" a spacer, and a \"hinge\" plate. The hinge plate has two flat surfaces with a tapered hole that holds the spacer. This assembly procedure ensures that the hinge and the spacer are perfectly aligned. The invention also aims to achieve the base structure assembly using only two bolts. These features make the invention a distinctive option on the market."

Problems solved by technology

First of all, the machining tolerances cannot ensure a good coupling between the base structure and the frames.
Moreover, though very simple, the assembly process needs several bolts and, consequently, a long assembly time.

Embodiment Construction

[0008]With reference to the above mentioned tables:

[0009]FIG. 1 is the sofa structure according to the invention;

[0010]FIG. 2 shows the base structure;

[0011]FIGS. 3 and 4 show a detail of the plate called “hinge”, respectively;

[0012]FIG. 5 shows the hinge between plate and frame;

[0013]FIG. 6 shows the detail of the shaped pin;

[0014]FIG. 7 shows the coupling between cam and roll;

[0015]FIG. 8 shows the front leg of the structure;

[0016]FIG. 9 shows the fastening of the front leg;

[0017]FIG. 10 shows a detail of the second fixation plate.

[0018]As already mentioned, the main purpose of the invention is to reduce as much as possible the clearance of the sofa base structure (1). FIG. 2 shows the sofa base structure that supports the hinged frames in the bed and sofa configurations, and comprises two identical elements, called “small legs” (4), and a spacer (5). Such a spacer is a rectangular pipe, which constrains and lets the two “small legs” be parallel to each other. In FIG. 3 is shown t...

Abstract

Sofabed with innovative position adjustment mechanism and a fast assembly process, comprising padding elements, a base structure (1) a plurality of mutually hinged frames (2) supported by said base structure and supporting said padding elements, and a kinematic mechanism (3) to change the frames positions; moreover, the base structure comprises two identical elements, named “small legs” (4), a spacer (5), and is characterised by a “hinge” plate (6) consisting of two flat surfaces, fixed on the small leg (4), which consists of two flat surfaces with an almost rectangular hole (7); said hole is tapered on one side (8) to lodge the spacer (5). This assembly procedure removes the clearance in the coupling between the hinge (6) and the spacer (5) and obtains a perfect perpendicularity between the spacer and the “small leg” (4). According to a subsequent aim the base structure assembly is realised by only two bolts.

Description

TECHNICAL FIELD[0001]The present invention relates to a convertible sofa bed provided with an innovative position adjustment mechanism and a fast assembly process.[0002]In the state of the technique there are already some realizations of convertible sofa beds. They normally comprise (FIG. 1) padding elements, a base structure (1), and a kinematic mechanism (3) to change the frames positions; the required features of said sofa beds are an easy assembly process, an easy conversion from bed configuration to a sofa configuration and vice versa, and also to be comfortable.[0003]The applicant, in this field for many years, has already patented (EP 1020142) a sofa bed characterised by a kinematic mechanism that allows the front legs wheels to stay close to the ground in both positions, a mechanism which blocks the relative rotation between the seat frame and the back frame and a simplified assembly process.[0004]Notwithstanding the remarkable inventive step in this technical field, this in...
