Description

Concealed hinge

Technical field

The present invention relates generally to the concealed hinge for door, window and closure, more specifically to following The object of feature：It can rotate successively on two axis, therefore allow the opening radian of 180 degree, and also beyond setting It is equipped with the door or panel of the bearing being superimposed upon on framework.

Concealed hinge is the hinge that a kind of insertion is arranged in the structure of door or window frame, however, with from outside Traditional type hinge it is different, concealed hinge is sightless when the door closes.

Concealed hinge is applied to wish the situation for avoiding any extra encumbrance, and former for attractive in appearance or safety Cause, when door or panel are closed, the preferably sightless situation of hinge.

Background technology

So far, concealed hinge can be divided into two major classes：Do not allow door to be opened to the hinge of 180 degree, and allow door Open the hinge up to 180 degree.Operating principle between both hinges is generally dramatically different.First type includes being applied to door Fixed frame on the first support member, rotary shaft is set in the inside of first support member, door-plate is fixed on by means of arm In rotary shaft, arm, which is shaped as, allows rotation as wide as possible.

Such concealed or concealed hinge allows generally for about 120 degree of maximum open, because frame part The position of interior rotation axis is because the geometrical interference between door leaf or panel and framework is without allowing larger rotation.Second The concealed hinge of type allows door leaf rotation to reach 180 degree, support member of such hinge generally by being fixed on framework Formed with another support member being fixed on door leaf or panel.The two support members are connected with each other by bar pivotally, and And there is rotation and the aggregate motion of linear displacement relative to these support members, these bars.

Embodiment

Figure (Fig. 1 of refer to the attached drawing and shown various pieces；2；3a；3b；3c；3d；4a；4b；4c；5a；5b), this patent The concealed hinge of application includes internal support 1 and external support component 4, to pass through the retaining element or spiral shell that are inserted into hole 20 Bolt is fixed on framework and door leaf or sash.

Support member 1 and 4 is all respectively arranged with two parallel surfaces, for internal support 1 surface 2 and 3 and be used for The surface 5 and 6 of external support component 4.Away from each other, the gap accommodated needed for linking arm 19 is left therebetween in the surface.Linking arm Away from each other, the gap needed for the one or more action bars 14 of receiving is left therebetween.The action bars 14 is fixed at one end External support component 4, open slot 15 therein can be accommodated by the part of locking member 11 by being provided with the other end.

The both ends of linking arm 19 pass through the inner pin 16 with internal axis 9 and the quilt of exterior pin 17 with outside axis 10 It is connected to internal support 1 and external support component 4.Inner pin 16 and exterior pin 17 are fixed to the corresponding He of internal support 1 External support component 4, and be inserted into hole 21 and 23.These hole positions have tolerance on linking arm 19 so that linking arm 19 on Corresponding pin 16 and 17 rotates freely.

The parallel surfaces 2 and 3 of inner support member 1 are both provided with groove 35, and mirror images of each other, each groove is with being centrally located at Circular section 7 on portion's axis 9, lead to the final section 8 relative to the internal radial arrangement of axis 9.

Locking member 11 passes through linking arm 19 using slit 22, is inserted into groove 35, along the groove slidably. Slit 22 is shaped such that when linking arm 19 rotates relative to internal axis 9, and locking member 11 is restricted in linking arm 19, It is dragged to rotate and allow it to advance along the whole path as caused by groove 35.Locking member 11 is by spring 12 along relative to interior The radial direction of portion's axis 9 is promoted, and spring is held in place in the suitable chamber 13 inside linking arm 19.

When opening stage starts, external support component 4 rotates relative to internal axis 9, and action bars 14 prevents outside axis 10 rotation, in this stage, the locking member that action bars 14 is located in the open slot 15 of the end of action bars 14 by being inserted into Part 11 is kept, and action bars 14 is fixed on the external support component 4.The lock operation bar 14 of locking member 11, until the locking Element is located in the circular section 7 of groove 35.

When action bars 14 can depart from from locking member 11, rotation axis is transformed to outside axis 10 from internal axis 9.

Closed when in the rotation of external support component 4 and the combination formed by linking arm 19, action bars 14 and locking member 11 The above situation occurs when internal support 1 reaches some Angle Position, wherein, due to the thrust of spring 12 and action bars 14, lock Determine the radial segment 8 that element 11 enters groove 35.

Between this stage that external support component 4 rotates on internal support 1, internal axis 9 and outside axis 10 Exchange is rotated, because the locking member 11 into the radial segment 8 of groove 35 stops that linking arm 19 supports relative to inside The motion of part 1 simultaneously discharges action bars 14, continues so as to allow attachment to the external support component 4 of action bars 14 relative to outside axis 10 rotations, and no longer rotated relative to internal axis 9.

During dwell period, since the maximum open position of hinge, external support component 4 revolves relative to outside axis 10 Turn, until the end 15 of action bars 14 contacts with locking member 11, locking member is carried it into the circular section 7 of groove 35.

Due to the different paths that the shape and locking member 11 and action bars 14 of open slot 15 follow, locking member 11 exists The movement of the radial segment 8 of groove 35 determines constraint of the action bars 14 to locking member 11.

In fact, this stage rotated in action bars on outside axis 10, track row of the action bars 14 along bending Enter, and the path that the radial component 8 of the groove 35 along on by internal support 1 at this stage of locking member 11 provides is advanced.

The different paths that action bars 14 and locking member 11 are followed so that the locking member is sandwiched in consolidating for action bars 14 Have to advance in itself due to the end 15 of external support component 4 and action bars 14 to leave between the path of locking member 11.This So that external support component 4 is prevented from the rotation of outside axis 10, while linking arm 19 is released from internal support 1 Put, so as to allow hinge by being rotated relative to internal axis 9 to completely close.

In order to increase the mobility of the mechanical strength of hinge and operation, parallel position installation that can be therebetween is more grasped Make bar 14.

It is excellent for support member, linking arm and action bars on realizing the material of the concealed hinge according to the present invention Choosing preferably uses abrasion-resistant stee using the cold-rolled steel of cutting and printing for the material of locking member and pivotal pin.Alternatively, prop up Support member, linking arm and action bars can be made of die casting or model casting.
