Abstract

The utility model relates to a bearing with linking hinges, which is suitable for bearing the demountable shelves of tables, furniture, etc. The bearing with linking hinges comprises a butterfly hinge. One side wing of the butterfly hinge is hinged with a plane hinge and the other side wing of the butterfly hinge is hinged with a spring butt hinge. The linking action of the plane hinge and the spring butt hinge is used to open the butterfly hinge which is folded and enable the butterfly hinge to bear between two object planes which are vertical to each other. Similarly, the bearing with linking hinges is commonly used for bearing the oblique stands of shelves on wall surfaces. When the bearing of linking hinge is folded, the bearing of linking hinge catches on the back of a shelf, occupying small place. When the bearing with linking hinges is unfolded, the bearing with linking hinges becomes a bearing. Because the bearing with linking hinges is not fixedly connected with supporters, shelves can be freely dismounted. The process and raw materials of the bearing with linking hinges is similar to that of a butterfly hinge in market.

Description

Bearing of linking hinge

The utility model relates to a kind of compound interlock page or leaf spike, is applicable to the active shelves of vertical support such as desk furniture.

Existing interlock page or leaf spike is combined by metal spring, fixed page or leaf and moving page or leaf.The furniture of selling on market butterfly hinge is exactly this form.It decide the back side that page fixing is installed on folding square table panel and external desktop, when external desktop being pulled to the square table face when equal, fixed page or leaf opens, moving page or leaf turns down 90 ° thereupon, forms the square table panel of flat connection and the spike of external desktop.But, in the daily life, the panel state of many staked shelfs, as in the side of writing desk, that the side of square table, the front of corner table etc. are supported is rectangular, during the shelf of semicircle or shape such as fan-shaped, but be two mutually perpendicular plate faces.Again because practicality and the needs of safeguarding outward appearance require shelf actively to remove stage makeup and costume.So, the support of this mutual vertical plane of the just uncomfortable cooperation of commercially available butterfly hinge and the needs that shelf can actively be removed stage makeup and costume.

The purpose of this utility model is that a kind of interlock page or leaf spike will be provided, and it can serve as the spike between shelf and vertical with it supporting surface, and do not hinder shelf freely unload into attaching.

The utility model is finished in such a way.Because the butterfly hinge opens, moving page or leaf is turned back after 90 °, and the obstruction of the moving page or leaf that fixed page or leaf has been turned back can not be closed up and straight and upright, and it is equivalent to a straight-bar, can be as the oblique supporting of a staked shelf.The mode of opening the butterfly hinge is, at the hinged flat page or leaf in termination of a fixed page or leaf of butterfly hinge, and its fastening shelf back side.Leverage at the hinged spring hinge of side of another fixed page or leaf of butterfly hinge promptly is hinged at the side of its side with a long page or leaf, again a termination of long page hinged one can the fastening shelf back side flash page, and spring is set in this hinged place.Like this, just constituting with the flash page hinged place is fulcrum, attaches most importance in the fixed page or leaf of butterfly hinge hinged place, and the non-hinged end of long page or leaf is the lever in force.When the cocked long page or leaf of hand to perpendicular to the flash page face time, the butterfly hinge is just opened erects an oblique supporting that becomes between the shelf back side and the non-hinged end of long page or leaf.Because the not fastening supporting surface of spike, thereby supporting surface is not impaired.Simultaneously, because long page or leaf has significantly increased the contact-making surface of the strong point, reduced pressure; Add that the long page of vertical component the spike load passed to the hinged place of its end, make the unlikely downward slippage friction in spike contact supporting surface position; And the propping orientation is to meet supporting surface to stick, and do not draw together the wiping supporting surface, so can effectively protect the decorative coveringn of supporting surface.This is particularly important for higher class decorative coveringn.The gathering method of butterfly hinge is pulled moving page or leaf just to deciding to get final product when the page is equal with it as well-established law.Spring and side ear long page hinged place, termination are dashed forward and can the butterfly hinge after drawing in be overlayed in the shelf back side, make spike not account for the Tibetan in addition and put the place.

In sum, the utility model changes the support that is supported for mutual vertical plane of the flat object of well-established law butterfly hinge.Supported shelf is not fixedly connected on the supporting object, thereby can freely unload or attaching.During support, spike two is subjected to spacing, thereby good stability, and sliding friction supporting surface not, helps protecting the decorative coveringn of supporting surface.Receive at ordinary times to be affixed on to put and pull the back side, does not open the manual control of gathering and move easier yet the side of occupationing of land in addition.Because only need both wings expanding device, and have ready-made technology to follow, implement easily at the butterfly hinge.Required making material can be used the well-established law irony, or according to requirements such as the mechanical strength of different use occasions and decorative effects, with aluminium, mirror metal, stainless steel, duroplasts etc.Below with reference to accompanying drawing the utility model is described specifically.

Fig. 1 is the schematic diagram of the present utility model that expression is holding state

Fig. 2 is the schematic diagram of the present utility model that expression is rounding state

With reference to Fig. 1, in the frame of broken lines, the butterfly hinge for open configuration is equivalent to a straight-bar here.Because spring (not giving expression among the figure) between spring ［ 3 ］ and moving page or leaf ［ 4 ］ between its fixed page or leaf ［ 1 ］ ［ 2 ］, do not born the function of the external desktop of original gathering, so set spring ［ 3 ］ elastic force can correspondingly weaken, spring can be cancelled as shown like that between its moving page or leaf ［ 4 ］, and even can only keep spring ［ 5 ］ or spring ［ 6 ］.The right part of frame of broken lines is a flat page or leaf ［ 7 ］, and it is articulated in the end of the fixed page or leaf of butterfly hinge ［ 2 ］, and is anchored on the shelf back side ［ 8 ］, makes the strong point of spike and the rotating fulcrum of butterfly hinge, and the locating part of end.For manual control gathering mode is smooth, moving page or leaf ［ 4 ］ is turned back like that left as shown to good.The left part of frame of broken lines among the figure, long page or leaf ［ 9 ］ is hinged with flash page ［ 10 ］, and at axle Xiao middle part of hinged place around so that to the page or leaf spring ［ 11 ］ of direction of turning back to paper.Long page or leaf ［ 9 ］ is hinged with the fixed page or leaf of butterfly hinge ［ 1 ］, is down ear prominent ［ 12 ］.Flash page among the figure ［ 10 ］ the fastening shelf back side ［ 8 ］, long page or leaf ［ 9 ］ stands on flash page ［ 10 ］ side, and an end that will be the butterfly hinge of direct rod shape is erected.The position at flat page or leaf ［ 7 ］ flash page ［ 10 ］ fastening shelf back side ［ 8 ］ should be able to make fixed page or leaf ［ 1 ］ ［ 2 ］ face of the butterfly hinge that opens shape be advisable perpendicular to nearly supporting surface ［ 13 ］ limit of the shelf back side ［ 8 ］.Among the figure, long page or leaf ［ 9 ］ side is converted into reinforcement ［ 14 ］, and other page increased mechanical strength or reduce the thick needs of page or leaf, also can add reinforcement by common flanging or towards methods such as tongue and grooves.The position of long page or leaf ［ 9 ］ contact supporting surface ［ 13 ］ must be smooth bright and clean, and the not outstanding page of spring ［ 11 ］ external diameter and end pin is better as the bed course that covers multiple one deck cloth or rubber mass again.

With reference to Fig. 2, this is for pulling positive drive page or leaf ［ 4 ］, and the butterfly hinge draws in, and spring ［ 11 ］ and ear prominent ［ 12 ］ overlay state after the shelf back side ［ 8 ］ with the butterfly hinge.

Spring force should not be strong excessively can overlay butterfly hinge degree of being, in order to avoid it is not light to pull long page or leaf ［ 9 ］.Owing to use the occasion difference of spike,, should do to determine after the simple test so select the size of spring force for use.In addition, a length that is slightly larger than hinged outside diameter of cylinder should fixed page or leaf ［ 2 ］ corresponding end be extended in butterfly hinge fixed page or leaf ［ 1 ］ proximal head hinged place ［ 12 ］, makes such as shown mutual fork ground, two hinged places be convinced stacked.
