The depth of the recess is sufficient to prevent any contact of the end of the clip with the edge (11) of the back frame.

Description

Containing the blocking-proof system has the divan hinge mechanism of seat, bed and couch position

Present patent application relates to a kind ofly can adjust to what is called " bed " to divan, " sofa " and " chaise longue " be the mechanism of three kinds of positions (relax), the pad parts carry of divan is on two supports of making mutual converting motion that are made of angle bar, first kind of angle bar supporting the second kind of angle bar of support that forms seat cushion and then supporting the support that forms backrest, the above-mentioned angle bar that is supporting back bracket also is connected on the base member of divan by means of the hinge connector that the armed lever that can make mutual converting motion by two groups is formed, with collude the detent mechanism that pawl matches and be used for controlling above-mentioned two or three positions, except these functions, also be combined with the blocking-proof system integratedly.

In the divan of this pattern, exist owing to the excessive difficult problem that causes of the height of bindiny mechanism between the two stands.The existence of this mechanism has hindered the setting of mat on this position.This means needs to use two different mats, and one is arranged on the support that constitutes bed, and another piece is arranged on the support that constitutes backrest.

Former also once the someone propose to design a kind of bindiny mechanism that can eliminate or lower its height, but in the various solutions known to so far all because the support that forms backrest is excessive and change and be difficult to a block pad or mat even two seat cushions that link together are assemblied on the support of the support of formation seat and formation backrest with the distance between the support that forms seat.Mechanism in France's utility model certificate 2,547,1831 has just obviously run into this difficult problem, and relevant structure of the present invention is based on it, and wherein the space between two Connection Elements is quite big.

Thereby, the objective of the invention is to recommend a kind of mechanism, the part that in this mechanism, forms bracket component (supporting seat) and form bracket component (supporting backrest) have be provided with enough low tie point so that be assemblied on the two stands an integrally formed mat or by two mats that are connected to each other to.

In order to reach this purpose of the present invention, and reduce the part of stretching out as far as possible so that can use one to become whole mat or by two mats that are connected with each other and constitute to the top of above-mentioned hinged connection, the above-mentioned pawl that colludes is fixed on the angle bar that is supporting the support that forms seat with certain relation, and its shape makes it and can contact with the backstop that is provided with on one of above-mentioned movable linking arm on two different positions, and this linking arm is to be positioned at the most approaching above-mentioned linking arm that colludes pawl under present situation.

According to the present invention, the above-mentioned pawl that colludes also has curved surface in the one side, its shape to make that this curved surface bumped on above-mentioned backstop when support when the formation backrest entered (relax) centre position of what is called " chaise longue " between bed position and sofa position.

In a most preferred embodiment, jagged on the free end of above-mentioned armed lever, when the support that forms backrest enter its extreme higher position promptly during " sofa " position it and above-mentioned backstop join.

Has a kind of mechanism that can be adjusted to the back bracket that to sit the furniture of to lie at least with respect to the hinged seat support of sitting the furniture of to lie thereon three kinds of positions of bed, chaise longue (relax) or seat of the invention still further relates to of blocking-proof mechanism (anti-blocking), this mechanism comprises hinged claw, it can be with respect to this seat support motion under the effect of spring, and its claw can be included in two notches of the component ends that belongs to this back bracket at least.

This mechanism is known and often is used to the back bracket that can sit furniture of can lying is adjusted to three kinds of positions.These three kinds of positions are: a seat position, its back bracket are positioned at vertical or vertical substantially position; One is in couch position between common seat position and the bed position and final bed position, arranges in a line at the two hinged each other members that belong to respectively on this position on two supports of furniture.In its use location, this claw can easily turn in the respective slot under spring action, this claw is installed in rotation on the end of this seat support that can sit the furniture of can lying, is being provided with a plurality of notches on the back bracket with on the end of the hinged member of this seat support.

On the bed position, the hinged each other member that belongs to two stands is arranged in a line, and claw is inoperative to hindering mechanism at this moment.

In some cases, promptly when back bracket when lifted slightly described bed position just now, the contacting of limit portion of the member on claw and back bracket will be played inhibition to mechanism, turns back to pure bed position and just no longer may because the generation of this situation just makes the seat support rethink.

In order to overcome this shortcoming, the shape at position on above-mentioned notch of the member that is provided with above-mentioned notch is improved considering that when back bracket becomes bed position claw surmounts on the direction of these notches, its improved shape is to form a recess, and the degree of depth of recess should be enough to avoid the above-mentioned member on this claw continuation and the back bracket to come in contact.

The present invention goes about other details of 3 kinds of positions and various advantage will be fused in the explanation of this mechanism that can be adjusted to divan three kinds of positions of the present invention that is about to be illustrated.This explanation is carried out with way of example, but the present invention is not limited thereto.Various quotation marks are with reference to each accompanying drawing.

Suppose that the mechanism shown in the accompanying drawing is in the base or casing of combination or fixing Reference numeral 13 representatives in the accompanying drawings.First parts 14 that are connected on the base 13 are fixed parts, it and movable linking arm 15 and 15 ' hinged at hinge 16 and hinge 17 places.Linking arm 15 ' is subjected to the effect of return spring 18, and spring makes it move to arrow 19 directions.

And then linking arm 15,15 ' also is connected on the angle bar 3 that is supporting back bracket at hinge 20 and hinge 21 places.

Angle bar 1 is supporting the support that forms the seat part.The mat of being represented by chain-

dotted line

23 and 24 is installed in respectively on seat support and the back bracket.

Constitute the angle bar 1 of backrest and seat element and 3 hinged, on each

angle bar

3 and 1, form widened section for this reason, represent with

Reference numeral

25,26 respectively at bearing pin 2 places.

The ring as intermediate member of the usefulness of keeping at a distance slides on this bearing pin 2, and determines the distance between the plane, widened

section

25,26 place.

The height of widened

section

25,26 that belongs to

angle bar

3 and 1 respectively is high-visible in Fig. 5, and mechanism wherein is the position that is in " bed ".This height can't be for the mat of monolithic one or with 23,24 usefulness of representing for example bonding certain-length of bonding mode (representing with sequence number 27 in Fig. 6 and Fig. 7) and two mats formation obstacles of binding.

Because mechanism of the present invention can dispose the mat of an integral body, also can use the mat that is formed by connecting by two, this mainly be not only because form do not relate in being connected between the support of backrest and seat divan open with closing motion during the opening of change in size, and particularly owing to there be (fixing) to collude pawl 28, it is that the part of angle bar 1 and its curved surface gabarit provide fulcrum for a backstop 29 on the linking arm 15, and the very big effectiveness of mechanism of the present invention just can come into plain view.

In Fig. 5, colluding pawl 28 still is that backstop 29 is all inoperative.

With reference to figure 6 as can be seen backstop 29 be against to be positioned at and collude on the pawl 28 free-ended sides 30, and in Fig. 7, maintain same backstop 29 by colluding pawl 28, but determine by the above-mentioned curved profile that colludes pawl certain a bit on, (Fig. 7) its seat position is to put the linking arm 15 that 31 places are blocked on the linking arm 15 ' at this to be guaranteed simultaneously.

Because this arrangement makes mechanism of the present invention very compact, and can eliminate above-mentioned various inconvenience fully.

By means of using band to collude the angle bar of pawl 28, particularly form above-mentioned claw portion and the above-mentioned detent mechanism of colluding, can make this mechanism further become compact.

Angle bar 1 comprises the part that connects angle bar 3 by means of above-mentioned bearing pin 2 securely, also comprises the part that connects the claw 4 and the structure member of the support that forms backrest by the 2nd pivot pin 5.Claw 4 is as notch 9 on the

angle bar

3 and 10 stop device, and it is the main element that constitutes this detent mechanism.This claw 4 should be mounted to and can do to rotate with respect to angle bar 1 at the position of pivot pin 5, and is subjected to the effect of the return spring of extension spring 7 forms.

The state that notch 9 joins at claw 4 places and claw 4 being shown among Fig. 6, and can seeing the 2nd notch in Fig. 7, as seen is notch 10, and the top of it and claw 4 joins.

So just can design detent mechanism quite compactly, and can entirely put among the syndeton between the

angle bar

1 and 3 of mechanism.

Be also pointed out that the main effect of colluding pawl 28 and its curved profile.On a certain position, backstop 29 all is inserted into (Fig. 7 represents its seat position) among the breach 28 ' that colludes pawl 28.

On chaise longue (relax) position, pawl 28 is colluded in these backstop 29 in-positions 30 and prevention.This represents its " chaise longue " position.

No matter can understand immediately that from top explanation mechanism of the present invention can make

mat

23,24 install especially easily, be a whole mat or the mat that is formed by connecting as illustrating as an example in the accompanying drawing.

From following description, can be clear that other details and the various advantage of blocking-proof of the present invention system to obstruction of the present invention mechanism.This explanation provides with way of example, but the present invention is not limited to by it, and its each Reference numeral is relevant with each accompanying drawing.

Obstruction of the present invention mechanism be a kind of belong to angle bar 1 on the seat support at the position of bearing pin 2 with belonging to angle bar 3 on the back bracket locking mechanism of hinged pattern.

The end of parts 1 is provided with the hinged claw 4 of tape spool pin 5.Above-mentioned claw 4 is a square, and an end at its 6 places at the position is connected with extension spring 7, and the other end of spring is positioned on the position 8 of same parts 1.

During having the backrest of angle bar 3 to move up thereon, claw 4 enters easily and throws off

notch

9,10, can be adjusted to couch position, seat position respectively whereby.

When back bracket was put down into the bed position, an end of pointed claw 4 just entered its tram usually.

Yet more recurrent situation is, when back bracket being mentioned a little and put back to, because the edge 11 (Fig. 1 and Fig. 2) of the angle bar 3 on claw thereafter and back bracket contacts, will hinder (blocking) phenomenon.

According to the present invention, suggestion is provided with a recess 12 on the edge 11 of angle bar 3, and this recess must have enough degree of depth avoiding there is any unwanted contact therewith between the edge 11 in the end of this claw 4, thereby this element can be moved with free state.

Just because of this arrangement, just again need not worry from now on and after back bracket is lifted slightly, can not make this back bracket become the position that couches again, be i.e. complete horizontal level of arranging in a line with the seat support.

The present invention is not limited to above-described embodiment, can make many corrections thus, as long as they all fall into the scope of the attached all claims in back.
