Generally be the sliding door design among Fig. 1 a to 1c with 10 link lock of representing.This link lock has a latch member 30 by push rod or connecting rod 12 operations, and (Fig. 1 a) nibbles with (unshowned) locking steel plate that is fixed on the (not shown) doorframe and is incorporated in that (Fig. 1 c) remains on the position of an immigration in the unlocked position this latch member in locked position.This push rod or connecting rod 12 are bearing in a flanged plate or cover plate 20 back in the mode of knowing and can vertically move and be in transmission connection with lever operated (unshowned equally) connecting rod.

This latch member 30 is bluff bodies, and it is vertical by this connecting rod 12 and cover plate 20 in vertically.For this reason, the latter is provided with

pod

13,22, and its width is equivalent to the thickness (seeing Fig. 2 b, 2d) of locking element 30.Locking element 30 is supported by a casing 50 below push rod 12.This casing has a long box 52, the downside that flange 53 is fixed on, the most handy screw is screwed in cover plate 20 that this box constitutes with end integral body.Flange 53 extends through the bottom's push rod 12 that extend, that move freely between the top 59 of casing 50 and cover plate 20, and for this reason, its pod 13 all is provided with those widened sections 18 in each direction of operating.The width of casing 50 width best and pull bar 12 is unanimous on the whole, and this casing 50 does not take added space in door like this.The distance of the total length of the pod 13 on the push rod 12 and the length of casing 50 or guide rib 53 is designed so that push rod 12 always can reach enough vertically moving.In addition, the pods in (unillustrated) guide rib that is provided with along cover plate 20 and the push rod 12 corresponding with it guarantee in the stable of the height inner push-rod of whole door and guiding reliably.For the supporting and the guiding of latch member 30 in casing 50, this casing is provided with a longitudinal cut 54, and bottom of latch member 30 usefulness 31 inserts in this otch.

Latch member 30 is connected with push rod 12 by two lateral pins 32,34, is whole in these two lateral pin side direction insertion locking elements 30 or with it.First lateral pin 32 (below among Fig. 2 a) is designed to pivot pin and roughly is arranged on the mid point of latch member 30 bottoms 31.Press Fig. 2 b, it is engaged in first translot 14 in the push rod pod 13 with the profile ways of connecting and lies in the pin end that it stretches out from latch member 30 on two vertical steps 57 of longitudinal cut 54 both sides that constitute casing 50.Second lateral pin 34 is arranged in pivot pin 32 fronts (the pivot pin top of Fig. 2 a) in the locking direction.It has one than the slightly little diameter of pivot pin 32 and be positioned at second translot, the 16 a little higher than pivot pins 32 above following 31 of push rod 12 as guide finger.Be positioned at identical height so be positioned at the peak of two pins 32,34 below the cover plate 20.Pivot pin 32 is chosen such that to be that its bottom 31 of latch member 30 usefulness comes in the longitudinal cut 54 of casing 50 from the distance and the diameter thereof of bottom, and pivot pin 32 lies on the lateral step 57 simultaneously.In case promote push rod 12 by the connecting rod transmission, pin 32,34 is blocked by translot 14,16 immediately; Directly with push rod 12 motions, wherein lateral pin 32,34 is along sliding between cover plate 20 and the casing step 57 for latch member 30.In the centre position shown in Fig. 1 b, lateral pin 34 stops latch member 30 to shift out fully unexpectedly around the rotating shaft of pivot pin 32.Latch member 30 all leads on each position of function reliably.

Shown in Fig. 2 a and 2c, latch member 30 has the general shape of a rhombus, and it has one and is parallel to a U-shaped otch 36 and a back 42 of extending with the 31 one-tenth inclined at acute angles in base that extends on base 31.The top of U-shaped otch 36 is arranged essentially parallel to following 31 extends and constitutes a bill, and in the locked position of latch member 30, this bill stretches out from the pod 22 of cover plate 20 and is engaged in the locking steel plate on the doorframe.Because the shape of rhombus, U-shaped bottom 38 is shorter than bill 37, and in locked position, it blocks cover plate 20 as the lug boss of hook with its top 39.In addition, its bottom is provided with the limit (protruding back 40) of an inclination, and this hypotenuse is parallel to back 42 and extends.Transition region rounding between back 42 and the base 31 is so latch member 30 has the end 44 of a rounding.Generally speaking, latch member 30 has the shape of a closed lever.

Opening when loading in the direction of the sliding door of closing when hook 30, the guide finger 34 of bottom that is positioned at the hook lug boss 38 of the inside and is close to cover plate 20 is in the pulling force that is applied to by the locking steel plate on the bill 37 is introduced cover plate 20 as compressive stress bottom.The door always reliably locking.Locking steel plate and cover plate 20 are firmly encased by the hook end of U-shaped, and wherein, the distance between the height of otch 36 that is bill 37 and the hook lug boss 38 is equivalent to the thickness of locking steel plate and cover plate except a very little gap.For latch member 30 can embed in the locking steel plate all the time unquestionablely, the design of the free end of bill 37 has very little tapering.

In casing 50, longitudinal cut 54 stretches out the upper end of the pod 22 of cover plate 20 in the locking direction of latch member 30, and shown in Fig. 2 a and 2c, when door bolt closed, hook lug boss 38 was fitted in below the cover plate 20 fully.In opposite direction, longitudinal cut 54 is transited into a starting inclined plane 58.This starting inclined plane is nearby beginning below the outer back of the body 60 of casing 50 and was stopping before the lower end of pod 22 on the height of cover plate 20, that is it is tilted to the lower right along the opposite locking direction of latch member 30 and extends, and wherein the angle of the back side 42 of the angle of inclined-plane 58 and cover plate 20 and latch member 30 and its bottom 31 is identical.Before being transited into starting inclined plane 58, the longitudinal cuts 54 in the casing 50 are provided with another otch 62 of the hook lug boss 38 that is used for avaling.The outer back of the body 60 that this otch 62 extends to casing 50 is equally nearby also upwards defined by another inclined-plane 64 in the locking direction.But shown in Fig. 2 a and 2c, this otch 62 also can also further reduce total locking device with the overall height that reduces casing 50 thus to lower open mouth.On the height identical, on the both sides of casing 50 step 57, have otch 66, so that guide finger 34 moves into lug boss otch 62.

Fig. 1 a and 2a are illustrated in the locking hook 30 in the locked position, and Fig. 1 b represents the motion of opening of link lock 10.Push rod 12 between the upside 59 of the downside of cover plate 20 and casing 50 to lower slider.In this process, this push rod drives to be bearing in the locking hook 30 in the translot 14 and it is being opened in the direction and moves.Bill 37 is thrown off with the locking steel plate; The narrow bottom 31 of latch member 30 slides on the bottom surface 56 of the parallel crimping of the longitudinal cut 54 of casing 50, so hook 30 remains on its original position, that is hook 30 does not also rotate (seeing Fig. 1 b).Guide finger 34 along cover plate 20 slid underneath stops the accident of latch member 30 in this rectilinear motion process to rise.

When the rear end 44 of the rounding of latch member 30 arrives starting inclined planes 58, slide till bottom 31 planes of latch member 30 are fitted on the starting inclined plane 58 along this inclined-plane in the mode of forcing in this rear end.At this moment latch member 30 is automatically around its pivot pin 32 rotations.Bill 37 disappears in cover plate 20 back.Guide finger sinks to for 34 times in the mirror image symmetry otch 66 that for this reason is provided with on the step of both sides, and hook lug boss 38 then sinks to the bottom surface 56 of longitudinal cut 54.Above the otch 62 of hook lug boss 38, also be provided with another pit 67, so latch member 30 almost completely moves in the hook seat by cover plate 20 and push rod 12 for bill 37.Shown in Fig. 1 c and 2c, the back of the body limit 42 and the cover plate 20 of latch member 30 almost are locked in this final position to flush.Throwing one's back out of hook lug boss 38 40 flushes (Fig. 2 c) with the outer back of the body 60 of casing 50.

Promote push rod 12 if promptly lock direction in opposite direction, the hook lug boss 38 of locking element 30 rises to the ramp 64 of the same inclination of otch 62.This hook lug boss throws one's back out with it and 40 slides on inclined-plane 64 along cover plate 20 directions, thus make latch member 30 again around its pivot pin 32 rotations till guide finger 34 stops at cover plate 20.Bill 37 shifts out fully and is parallel to cover plate 20 again and moves into its locked position.

For the guiding of improving hook 30 and in order further to improve the reliability of locked position, the step 57 that constitutes in the both sides of the longitudinal cut 64 of casing 50 is designed to stairstepping.Shown in Fig. 2 a, the step 57 at first bottom scope of the casing below upside 59 50 extends.On the height of pit 67, this step 57 reaches upside 59 through the face 61 of a little inclination then, and like this, guide finger 34 is a little when locked position rises, and its just common and pivot pin 32 directly is close to the downside of cover plate 20.Pivot pin 32 then stops at inclined-plane 61 before nearby, so can not rise.

Can a plurality of such locking devices be set along push rod 12 or flanged plate 20 in case of necessity.This depends on that Yishanmen should carry out locking on how many positions.

The operating principle of locking device of the present invention is shown in Fig. 2 a to 2c schematic diagram.Fig. 2 a can find out that hook 30 that vertical and horizontal move is when locking is pulled and the situation of locking steel plate engagement.When opening lock, hook 30 is promoted by the push rod 12 of a lengthwise movement, and this push rod is covered by a cover plate 20 that is screwed on the crimping with screw.Hook 30 perpendicular to the rising of pushrod movement and descend by the slip limit on hook downside, front side and the

rear side

31,40,44 and the hook bottom that cooperates with the cross section of crimping groove 22 accordingly starting inclined plane 58,64 carry out.So starting inclined plane 58,64 becomes to make hook 30 to carry out the control element of functional movement with the hook end segment 44 of rounding with

hook lug boss

38,40 hooks.Also can regard latch member 30 as one can be around the double armed lever of pivot pin 32 rotations.Its first lever arm constitutes bill 37, and the second short lever arm then is made of relief angle 44.The latter plays the release effect to the immigration of latch member 30.

In order to open door, push rod 12 carries out lengthwise movement, at this moment hook 30 at first resembles the hook that does not sink to of a routine when the pure lengthwise movement by Fig. 1 b in 2/3rds processes of pushrod movement and the locking steel plate is thrown off, then hook 30 the push rod stroke last 1/3rd in press the bottom that Fig. 1 c or 2c pass through cover plate 20 and push rod 12 immigration casings 50.Its back of the body limit 42 of hook 30 usefulness almost stops at this final position with cover plate 20 with flushing.

In another kind of structural shape, link lock 10 has an additional braking and releasing device 100 except above-mentioned locking device.This device is used for making push rod or connecting rod 12 to stop in the unlocked position of latch member 30, and discharges again automatically after door lock closes, and the latch member 30 that loads at locking direction inner spring can be got back to its locked position automatically like this.For this reason, in the transmission of (unshowned) connecting rod, be provided with a compression spring, this spring prestressing when operation (unshowned) handle.In case when latch member 30 reached the maximum prestressing of final position that its moves into and this spring, push rod 12 just was fixed in its position by this braking and releasing device.(unshowned) rotary handle is by the original position that once dallies and get back to it.

Braking shown in Fig. 3 a to 3c and releasing device 100 are arranged on the top of a locking device along push rod 12.This brake release device has the braking member 130 of a double armed lever form that is connected with push rod or connecting rod 12 pressures.When latch member 30 reached certain position, first lever arm 132 of this double armed lever passed in push rod 12 and cover plate 20 enter vertically, and the second short lever arm 134 is then in the corresponding detent recess 158 of embedding casing 150 bottoms 155.Push rod 12 and cover plate 20 are provided with

pod

135 or 140, so that double armed lever 130 passes through, the width of pod is equivalent to the width of bar 130.

Cross section is that the bar 130 of square or rectangle is bearing in the below of cover plate 20 and can vertically moves in casing 150 that (Fig. 3 a).This casing has a long box 152, this long box with the whole flange 153 that constitutes in end be fixed on, the most handy screw is connected on the cover plate 20.Flange 153 extends through the push rod that can move freely 12 that extends between casing 150 and cover plate 20, for this reason, its pod 135 all is provided with those widened sections 138 in each direction of operating.The width of casing 150 roughly is equivalent to the width of push rod 12, so area occupied is minimum.The distance of the total length of the pod 135 in the push rod 12 and the length of casing 150 or guide rib 153 is designed so that push rod 12 always can reach enough vertically moving.For the supporting and the guiding of bar 130, in casing 150, be provided with a flat longitudinal cut 154, bar 130 planes embed in this longitudinal cut.For the reason of installing, whole box body 150 is designed to the vertical mid point mirror image symmetry with respect to it.So it can be connected on the cover plate 20 with screw in any direction.The pod 140 of cover plate 20 is in alignment with the Lower Half top of longitudinal cut.The width of the width of the width depending post 130 of pod or the longitudinal cut 135 of push rod 12.

Bar 130 is connected with push rod 12 by a lateral pin 142, and this lateral pin is as constituting one in the pivot pin insertion rod 130 or with this bar.Shown in Fig. 3 b, this pin 142 is between the first long lever arm 132 and short second lever arm 134, and these two lever arms are preferably whole.Press Fig. 3 b, pin 142 inserts to be realized in the translots 136 in the push rod pods 135 that profile connects and holds level with both hands with the pin that it extends laterally being placed on vertical step 157 that longitudinal cut 154 both sides constitute in the casing 150.Pin 142 is from cover plate or flanged plate 20 lockings of opposite side by being positioned at push rod 12 tops.

Bar 130 lies in the bottom 155 of casing 150,152 longitudinal cuts 154 in locked position, pivot pin 142 then is bearing on the both sides step 157.The second short lever arm 134 is positioned at the locking direction, and the second long lever arm 132 then is positioned at the casing 150 opposite with the locking direction.When making push rod 12 motion with the connecting rod transmission, pin 142 is blocked by translot 136; Bar 130 moves simultaneously with push rod 12 in casing 150, and wherein the pivot pin end is along sliding between cover plate 20 and the casing step 157.

The detent recess 158 of lever arm 134 accurately is arranged on the mid point of casing 150.This detent recess is the prismatic bottom 155 of stretching into longitudinal cut 154.The length of longitudinal cut 154 roughly is the twice of bar 130 length overalls.In addition, be provided with a leaf spring 170 in the top pod those widened sections 138 of the push rod 12 between bar 130 and cover plate 20.This leaf spring is with in the clamping slot 174 in a curved end 172 embedding casings 150.In addition, this leaf spring accurately is placed on the first half top of the prismatic grooves 158 of bar 130 with its free end 175.So this bar 130 always loads in bottom half 155 directions with an elastic force above groove 158.

In the locked position of latch member 30, bar 130 at first plane is positioned at cover plate 20 belows of longitudinal cut 154 of casing 150 (Fig. 3 a).The free end 175 of its pin microbend of leaf spring 170 usefulness is positioned on the long lever arm 130.

By lever operated latch member 30 time, push rod 12 along between cover plate 20 and the casing 150 to lower slider.At this moment this push rod drives the bar 130 that is bearing in the translot 136 and promote it along opening to be directed downwards in longitudinal cut 154.When latch member 30 reached its final open position soon, the pivot pin 142 of bar 130 was by the supporting-point of leaf spring 170.In case this supporting-point arrives pivot pin 142 back, spring 170 just loads the quarter butt arm 134 of following in long lever arm 132 back.Because its short size, this quarter butt arm are now-also as the free end 175 of leaf spring 170-be positioned at detent recess 158 tops, so it is pressed downward in the groove 158 by spring 170 and remains on this place (seeing Fig. 3 c).In order to reach reliable braking action, the rod end of bar 134 is with inclination slightly according to the groove angle or the shape of prismatic grooves 158, detent recess 158 is hooked in its end of bar 134 usefulness like this, so the push rod 12 in push rod return spring rightabout just firmly stops in the position that reaches.Because short lever arm 134 buckles in the detent recess 158, the first long lever arm 132 is downward by the hole 135,140 of push rod 12 and cover plate 20 simultaneously.Because the permanent spring-loaded of short brake arm 134 remains in this position this bar 132.Latch member 30 is positioned at its inflow location; Door just can be opened, and does not stretch out the locking hook that is in the way from the bead face of door.

When closing, door is buckled on the corresponding end-faces of doorframe with its bead face.The lever arm 132 present release effects of stretching out from cover plate 20.It rotates inwards around pivot pin 142, so second lever arm 134 just rises the prismatic grooves 158 of rod end in bottom half 155 with it.Braking is eliminated; So push rod 12 can move in closing direction again.The application position that fixing latch member 30 is got back to it by the recuperability of storing in the push rod transmission on push rod 12.Door is when closing on the automatic locking.By the suitable selection of

lever arm

132 and 134 length ratios, adjustment release is braked used power like this, and promptly braking and releasing device 100 do not hinder closing of door, but the accident of effective simultaneously prevention braking discharges.

Another structural shape of the present invention shown in Figure 5 can be realized the simple transportation and the simple and installation fast of link lock 10.

It usually is suitable that push rod 12 and cover plate 20 are divided into several sections processing.At this moment the part of taking apart for convenient transportation connects at the scene and installs.Each section of cover plate do not need to interconnect, because they firmly are connected in the crimping groove with screw, the push rod segmentation then must be fixedly connected, so that they can move freely in gate slot.

The Connection Block 200 that connection push rod shown in Figure 5 is used has a matrix 202 long, that be roughly rectangle.The downside of this matrix 202 is provided with four round pins 204 of arranging in a line, and in these round pins or the embedding matrix 202, perhaps constitutes whole with this matrix.Opposite one side of downside, matrix 202 is two ends 206 roundings in vertically.

Locked 10 o'clock at installing connecting rods, with in respective aperture 208 two round pins 204 insertions corresponding push rod end 207 on, wherein can with friction connection clamp-on in hole 208 respectively by round pin 204 for Connection Block 200.Round pin 204 is arranged to the accurate centering that straight line has guaranteed Connection Block 200 and push rod 12, thereby has guaranteed permanent firm connection.Because the matrix 202 of Connection Block 200 is by the profile comprehensive surrounding of door, so even this matrix can not drop out from hole 208 after using in the long period yet.The end 206 of rounding has always guaranteed the lengthwise movement flexibly in gate slot.Except the structure and reliable functioning of being convenient to operation and installation, Connection Block 200 has another important advantage: link lock 10 can be at any time promptly only be used with the central bead of the weak point that installs all the time even without the connecting rod elongation with just not doing not have any change, because-under any circumstance all covered in the end of the push rod of prior art comparison-lock one side by cover plate.

The invention is not restricted to above-mentioned various structural shapes, but the modification structures of multiple mode can be arranged, for example casing 50,150 not only can but also can constitute whole with check mechanism with locking device, but it also can be made up of the casing of two hemihedrism, and hole and available screw that this two halves casing is provided with the mirror image symmetry interconnect.

From every claim, illustrate and accompanying drawing in whole feature and advantage of drawing comprise that CONSTRUCTED SPECIFICATION, space are arranged and processing step not only can use separately but also can carry out various combinations.
