Abstract

Sofa bed with innovative 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

Has the divan that is used to assemble with the element of the innovation of position adjustments

Technical field

The present invention relates to a kind of two purpose sofas-beds, it is provided with the position adjusting mechanism of innovation and one assembling process fast.

Background technology

In the prior art, some two purpose sofas-beds have been arranged.They generally include (Fig. 1) packing elements, underlying structure 1 and a motion 3 that changes frame position; The desired feature of described divan is a simple assembling process, changes the ground sofa configuration like a cork from bed structure, and vice versa, and also comfortable.

The applicant is in a lot of years of this area research, obtained a kind of patent (EP1020142) of divan, it is characterized in that one can make foreleg wheel rest in the motion that ground stops on two positions, one can the blocking seat framework and the back framework between mechanism in relative rotation and the assembling process of a simplification.

Although this invention has significant creativeness in this technical field, it still has some shortcomings.At first, its machining tolerance can not guarantee good connection the between underlying structure and the framework.In addition, although it is very simple, assembling process needs a plurality of bolts, and the result needs a very long built-up time.

Summary of the invention

The invention is characterized in the judging standard in market, because it is a kind of such sofa: it comprises packing elements, underlying structure 1, a plurality of described underlying structures of having that are hinged support and support the framework (2) of described packing elements, a motion (3) that makes the framework conversion and be parked in desired location; In addition, underlying structure comprises two components identical, is called " shank (4) ", keeper (5), and it is characterized in that be installed in " hinged " plate (6) on the shank (4), it comprises that two have the flat structure that is almost rectangular opening (7); Be tapered on the described Kong Zaiyi side (8) to hold keeper (5).This assembling process has been removed the bonding gap between articulated slab (6) and the keeper (5), obtains between keeper and " shank (4) " perfectly vertical.

According to the purpose of back, by the only assembling of two bolt realization underlying structures.

To point out these and other advantage in detailed description of the present invention, the numeral 1/5,2/5,3/5,4/5,5/5 in the description references table wherein provides preferred and non-limiting embodiment.

The specific embodiment

As mentioned, main purpose of the present invention is the tolerance that reduces sofa underlying structure 1 as much as possible.Fig. 2 provides the underlying structure of sofa, the hinged framework of this support structure bed and sofa structure, and comprise two components identical, this keeper with a keeper (spacer) (5) that is called " shank 4 " is a rectangular tube, and its qualification also makes two " shanks " parallel to each other.In Fig. 3, plate (6) is shown, it makes and fits together between shank and the keeper.Described plate comprises two flat surfaces, because its function, it is called " hinge ".It is fixed on " shank ", has the hole (7) that is almost rectangle, and tapered side (8) is arranged.As shown in Figure 4, tight a bolt (9), keeper (5) is forced to the tapered side (8) that enters into hole (7).Therefore, because this assembling process, three important conditions are complementary: eliminated the gap in combining between articulated slab (6) and the keeper (5); Perfectly vertical between keeper (5) and " shank (4) "; Only by two bolt assembling underlying structures (bolt of each leg).

Another function that is called the plate (6) of " hinged " is, as shown in Figure 5, and (11) hinged frame (10) on every side in the hole.The framework rotation moves to second desired location that is limited by barrier element from horizontal level.Desired location is limited by the hole on the framework, promptly will change the inclination angle, needs to change the hole.Rotation and barrier element realize that by special-shaped pin (12) end (12 ') of special-shaped pin is bonded in the hole of framework, as rotating shaft; And pin part (12 ") is as the barrier element of framework.A back-moving spring moving pin: pull-off spring tension force, pin is inserted in two holes of two " hinged " plates (6).By simple moving, and without any need for instrument, framework (10) can be separated and be fixed on another hole, obtains the different angle of sofa backrest.

A roller (13) is arranged on the free end of " shank " (4), and the profile complementation of its section and cam (14) is with as shown in Figure 7: hold cam when mechanism is the sofa structure.Roller has central recess (13 '), has only several mm wides, and cam is contained in wherein.This makes cam and roller self-centering, prevents because misalignment and inoperative.Second element (15) links to each other with cam (14).It is called as " foreleg ", as shown in Figure 8, and can be around axle rotation one determining deviation.As sofa seat, foreleg (15) also is fixed to certain angle.Obtain the desired position by additional articulated slab (16), the single bolting of articulated slab, and have two barrier elements: first (18) are realized on leg, are realized on cam for second.By these barrier elements, plate remains on desired location with leg.Barrier element can perhaps be sold to move on the exterior contour of leg (15) or cam (14) and realize by pin being inserted in the complementary hole.Provide an embodiment of described plate among Fig. 9.Another function element of fixed head is to become 90 ° part (20) with described fixed head, and this part (20) has a plurality of holes to be used for fixing the plate of different sofa patterns.

As mentioned, further purpose of the present invention is to reduce the quantity of bolt in the sofa assembling process.Need 14 bolts in the prior art, the present invention only needs 6.In fact, each side of framework has three bolts: first is fixed to keeper (5) on " shank " (4), and second is fixed to cam (14) on the framework, and the 3rd is fixed to back leg (21) on the framework (2).
