Description

The steel folding beds of using more

The utility model belongs to the steel fold furniture, and it is to deposit in below the desk after folding or the steel folding beds of using in the built-in wardrobe more.

Though various in style on the furniture market at present, the collapsible furniture of steel takes up an area of little and convenient and practical characteristics with it, occupies critical positions all the time.The applicant had once invented the steel folding bed with plane four connecting rods and space four bar linkage mechanism, but they are to be combined in the sofa case after folding, plane width after folding is always more than 800 millimeters, it is more to occupy the plane, can't with the bed body after folding vertically be attached under the desk or in the built-in wardrobe.

The purpose of this utility model provides a kind of steel folding beds of using that can deposit in after folding below built-in wardrobe casing or the desk more, and it is little that it occupies the plane, and folding convenient is of many uses.

The utility model be achieved in that it comprise one can be along the folding bed that is folded transversally into " case " body, it is characterized in that connecting a rotary folding mechanism in the below of " case " body, this mechanism comprises middle rocking bar, the back rocking bar that is hinged on back side frame under " case " body, the lower end of two rocking bars all is hinged on the fixed head, and have spring to connect, between back rocking bar and back side frame small rod is arranged, its end is hinged on the rocking bar of back, the other end is combined in the chute of back side frame by slide block.

Below the side frame of back, fixed a baffle plate:

Saidly can comprise the six roots of sensation crossbeam of forming bed surface along the folding bed that is folded transversally into box-like body, respectively there are five hinged successively side frames both sides, at the front portion and the middle part of side frame one group of four connecting rod fold mechanism are arranged respectively simultaneously; Anterior quadric chain comprises the little bar that is hinged on respectively on the preceding side frame, and the front support rod of side frame and preceding short frame contact before being articulated in, and the preceding stock on the short frame before being hinged on are hinged on the short strut on the front support rod in addition.Preceding stock, little bar and short strut three's the other end is hinged, the also hinged front rod in the termination of preceding stock, its other end is hinged on the middle side frame: the linkage at middle part comprises middle pole, it is hinged on the middle side frame, stock in its middle and upper part is hinged, on the connecting rod, middle rod hinge connection was between middle side frame and back side frame during the other end of middle stock was hinged on.

The utility model has the advantages that it can be along laterally bed surface being folded into " case " shape, and then half-twist, make " case " body erect, leptoprosopy is up, therefore reduced floor space, can be combined in the below of desk, workbench, the bed body that the fixing baffle plate in side frame below will be folded up under using blocks, and is elegant in appearance, act freely, can be provided in the night shift room or family of office, enterprise, of many uses, practical.

Details of the present utility model provides by following examples and accompanying drawing thereof:

Fig. 1 is a kind of structural scheme of mechanism of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is a upset fold mechanism motion schematic diagram among Fig. 1.

With reference to the accompanying drawings:

Folding bed of the present utility model comprises 24,18,31 of the crossbeam of forming bed surface, 25,26 and the afterbody crossbeam 27 at middle part.Five hinged successively side frames are respectively arranged in the crossbeam both sides, they are preceding side frames 23, preceding short according to 19, middle side frame 16, short frame 10 in back and back frame 9 are between preceding short frame 19 and the middle side frame 16, between the short frame 10 of middle side frame 16 and back, also be respectively equipped with slide block mechanism 14,13,30 between the short frame 10 in back and the back side frame 9.At middle part, bed side frame front portion one group of four connecting rod fold mechanism has been installed respectively.Little bar 22 on the side frame 23 before being hinged on is forwardly arranged, the front support rod 28 of side frame 23 and preceding short frame 19 contacts before being hinged on, stock 20 on the short frame 19 also has short strut 21 before being hinged on, its end is hinged on the front support rod 28, and the other end and little bar 22, stock 20 are hinged on a bit.The also hinged front rod 17 in the termination of stock 20 is during its other end is hinged on the side frame 16.Pole 15 during four connecting rods at middle part comprise, side was according to 16 during it was articulated in, and on the connecting rod 11, the other end of middle connecting rod 11 was hinged on the side frame 9 of back during its middle and upper part is hinged middle stock 12, the other end of middle stock 12 were hinged on.

The rotary folding mechanism that below side frame behind the rear portion 9, is provided with, the middle rocking bar 8 of side frame 9 after being articulated in, back rocking bar 5, both bottoms all are hinged on the fixed head 1, link mutually with 2 with connecting plate 7, spring 4, connecting plate 3 between the two, wherein connecting plate 2 is to fixedly connected with back rocking bar 5, and angle is constant.The also hinged small rod 6 on side frame 9 tops, back, its other end is connected in the chute on the side frame 9 of back by bearing pin.

When the utility model folds, crossbeam 24 before holding in the palm, front support rod 28 and preceding side frame 23 change 180 ° around axle, and preceding short frame 19 commentaries on classics erect for 90 °, side frame 16 changes 180 ° around axle in holding up again, and then short frame 10 commentaries on classics in back erect for 90 °, and side frame 23 and back side frame 9 are for going to the bottom before forming, in above side frame 16 is, the short frame 10 of preceding short frame 19 and back is " case " body of side.

With reference to the accompanying drawings 3, " case " body rotation after needing to fold erects, and then pulling back side frame 9 makes C point rotate counterclockwise around A point left, the E point, and the D point then turns left around the B point, and while F point is slip to the right in chute.After the D point turns over the EF line, middle rocking bar 8 begins revolution under the effect of spring 4, when back rocking bar 5 goes to horizontal level, and 8 one-tenth upright positions of middle rocking bar, promptly back side frame 9 is pressed close to middle rocking bar 8, is positioned at the flat casing that crouches in side frame 9 tops, back and becomes plumbness to finish 90 ° of rotations thereupon.Being fixed in baffle plate 29 below the side frame 9 of back this moment blocks " case " body and makes outward appearance neat and artistic.

If want folding postrotational bed surface is launched, as long as under the hand-power effect, pulling " casing " is moved counterclockwise, 8 of back rocking bars are around B point dextrorotation (clockwise), after D ' walks around F ' E ' line, power assistant spring 4 plays a role, and makes it continue to return back to original position, and then " case " body above the back side frame 9 is the level of state.
