The specific embodiment
With reference to Fig. 1, be depicted as the lock of tongue more than, comprise being enclosed in the interior lock housing 1 of mortise that door leaf (not shown) edge is recessed on.Lock housing 1 generally includes one lock box 2 in two big vertical planes that constitute lock housing 1, with 2 one-tenth integral body of lock box or be rigidly attached to panel 3 on the lock box 2, a hole 3a (as shown in Figure 2) is arranged so that be connected in the not really dark recess or groove that on door leaf edge, forms by the screw (not shown) in the use on the panel 3, and the lid of flat type or cap (not shown), it is parallel to lock box 2 extensions and can be connected on the latter with pulling down.
Lock the latch bolt 4 of the inside that also comprises lock housing 1 and the driven member of operating by the door handle (not shown) 5, as be used for spherical or shaft-like door handle, dead bolt 6 and the lock barrel that has the lock tube 8 of the available key turns that matches of manual operation latch bolt 4.
Latch bolt 4 generally includes head 11 and shank 12.For example the head 11 of prismatic passes the hole 13 that is substantially rectangle on the panel 3, and head 11 is by these hole 13 guidings and mobile in the horizontal direction.Head 11 comprises that but one is positioned at relative with vertical side with the vertical side on the parallel plane of lock box 2 and one side that tilts.The last lower horizontal plane of head 11 has two groove 11a and 11b (as shown in Figure 4) respectively, and groove 11a and 11b and be respectively formed at the projection 13a of last lower limb in hole 13 and the profile of 13b by complementation cooperatively interacts can be inducted into head 11 in the described hole.
Shank 12 is made up of columniform bar, and its end and head 11 are rigidly connected, and is slidingly mounted in the supporter 14 (representing clearlyer in Fig. 4) that the otch by lock box 2 forms.The other end of shank 12 is supporting the end piece 15 that is rigidly attached on the described shank 12.End piece 15 be shaped as square or rectangle, the size of its horizontal side basically with lock box 2 and lid between spacing consistent so that when head 11 is fully retracted in the lock housing 1, prevents or limit shank 12 and rotate around the longitudinal axis.With the axis normal place of shank 12, as near bearing 14, lock box 2 and two rectangular openings 16 that cover relative formation allow latch bolts 4 around the longitudinal axis A of shank 12 Rotate 180 °, its rotation mode will be described in detail below.
As shown in Figure 1, the spring 17 on the lock housing 1 is exerted pressure to latch bolt 4, makes it rest on resting position, and at this moment, head 11 parts reach outside the lock housing 1.Spring 17 is for example formed by the compression spring, and the one end is supported by end piece 15, and the other end is supported by the edge 2a of lock box 2.Spring 17 is located in position by the free end of bar 12, and spring 17 1 ends are installed around bar 12, and the other end is installed around the inner convex platform 18 of edge 2a.
When described lever 22 is in its resting position, also be in resting position corresponding to latch bolt, lever 22 is supported on the stopping means 24 at the projection 22c place of lever 22.
Described stopping means 24 is formed by a Metallic rod of passing the extension of lock housing 1 thickness, and its each end all is installed in the groove 25 of each wall of lock housing 1.For example, stopping means 24 remains in each groove 25 by the enlarged 24a in lock housing 1, and therefore, in lock housing 1, the cross section of bar is greater than the width of each groove 25.At groove 25 places, bar has a cross section 24a, and the width of itself and groove 25 is suitable.Can also arrive stopping means 24 from lock housing 1 outside by the hole on the panel 3 26.By inserting proper tools the described hole 26 from panel 3, as screwdriver or T staple, described stopping means 24 can move along described groove 25.
Each groove 25 is arc, so that limit two settling positions of stopping means 24 at each end of groove 25.Each groove 25 all is positioned on the lock housing 1, so the so-called moving position of stopping means 24 is lower than the so-called non-moving position of stopping means 24.The non-moving position of so-called stopping means is described in Fig. 4, the position of stretching out fully from lock housing 1 corresponding to head 11.So-called moving position is described in Fig. 1, the position when making lever 22 be in resting position corresponding to stopping means 24.For example, each described groove 25 is in vertical direction basically in lock housing 1, and therefore, when user's operated door handle, stopping means 24 can be got back to its moving position under the effect of gravity, and this point will be introduced in the back in detail.In addition, the shape of the projection 22c of lever 22 makes described projection 22c all overlapping with the middle part of groove 25 on the moving position of stopping means 24 or non-moving position, therefore, when unclamping door handle, stopping means 24 passes through the effect of the projection 22c on the lever 22, and is retained in each groove 25.So stopping means 24 will be supported on the either side of projection 22c at its moving position or non-moving position.
As shown in Figure 1, spring 20 is set in the lock housing 1, being used for exerting pressure to driven member makes it be in resting position, and this moment, driven member supported the position that this unclamps corresponding to door handle by stopping means 24.One end of spring 20 is supported on the edge 2a on the lock box 2, and the other end is contained on the button 19.Spring 20 is on the one hand by button 19 location, and by inner convex platform 29 location of described edge 2a, spring 20 is installed around this inner convex platform 29 on the other hand.Button 19 is made up of T shape Metallic rod, and its supporting leg is contained in the spring 20, and its horizontal stripe 19a is supported among the mount pad 5c of driven member 5 on the one hand, is supported on the other hand (referring to Fig. 8) in the spring 20.Mount pad 5c allows bar 19 to pivot with respect to driven member 5.The degree of depth of mount pad 5c approximates the diameter of spring 20 greatly, thereby can prevent that stopping bar 19 ejects.The diameter of described horizontal stripe 19a is greater than the diameter of spring 20, thus compression spring 20 can allow the rotation of driven member 5 clockwise directions the time.The bar of button 19 can be spring 20 guiding in its compression and when stretching.The free end of button 19 can be resisted against on the lock housing 1, and it can limit driven member 5 angular clearances and the retraction of latch bolt 4 in lock housing 1 in the clockwise direction with driven member spring 20, for example when the leading edge of head 11 is concordant with the external surface of panel 3.For the ease of the assembling of each assembly in the lock housing of door lock, a shaping boss 27 inwardly outstanding in lock box 2 is set.Before driven member was installed, when packing in lock housing together with its spring 20 button 19, this shaping boss 27 can be used as the block of button 19, thereby avoids spring 20 to be ejected.Then, button 19 is loaded among the mount pad 5c of driven member 5.
The slot 34 that a level is arranged in latch handle 32, lower limb forms the zigzag thing 35 that can limit a plurality of latched positions on latch handle 32.These latched positions are decided corresponding to lockset position of coupler, single twist lock and two twist locks are decided.Give prominence to outside the slot 34 of latch handles 32 with the joint 36 of lock box 2 riveted joints, thereby allow dead bolt 6 to be guided in the horizontal direction.
Lock barrel 8 comprises key bit 8a, and key bit 8a can act on the following zigzag thing 35 of latch handle 32, also can act on the bottom and the tablet 37 between the latch handle 32 that embeds lock box 2.
Described tablet 37 can move by the translation direction transverse to dead bolt 6 in a plane that is parallel to lock box 2 planes.Have one on the tablet 37 substantially perpendicular to the oval chamber 37b in hole 34, joint 36 passes described tablet 37 in described chamber 37b.Tablet 37 is as locking member.For can with top zigzag thing 35 co-operatings on the latch handle 32, the projection 37a that stretches out of direction towards lid is arranged on the described tablet 37, described projection 37a is subjected to being in the pressure of the helical spring 38 in the zigzag thing 35.Described tablet 37 bottoms are triangular in shape, and are placed as with key bit 8a track and overlap, thereby can be moved by key bit 8a.
About the structure of dead bolt and operational example as in document FR-A-2 711 713, describing.
Below, the operation of the lock among the present invention is described.From the state of Fig. 1, in Fig. 1, stopping means 24 is in its so-called moving position, promptly in the lower end of groove 25, and stops lever 22 at the projection 22c place of lever 22.The last projection 22a of described lever 22 is vertical basically, and dead bolt 6 is at the retracted position of lock housing 1, and latch bolt 4 is in its resting position, and promptly latch bolt part from lock housing 1 is stretched out, and driven member 5 is in and the corresponding resting position of the horizontal level of lever.
When user's clockwise direction revolving door handle, driven member 5 turns clockwise around the B axle, simultaneously, and driven member 5 compression springs 20, the rotation of button 19 restriction driven members 5.The finger piece 5a of described driven member 5, the end face collaborative work with recess 28a on the lever 22 drives described lever 22 and rotates on same direction around the B axle.The last projection 22a of lever 22 acts on the end piece 15, and end piece 15 is moved horizontally to the opposite side of panel 3.Make shank 12 and head 11 also along with doing same moving, mobile phase with distance, head 11 will be in the position that is withdrawn in the lock housing 1, this moment, door lock was in the position shown in Fig. 3.
When the user unclamped door handle, spring 20 discharged, and makes described driven member 5 rotate in the counterclockwise direction, reached the resting position that limited device 24 supports up to described driven member 5.Simultaneously, end piece 15 is pushed to its resting position, and spring 17 discharges.End piece 15 activation lever 22 are rotated in the counterclockwise direction, stop up to the limited device 24 of the projection 22c of lever 22.Moving of the last projection 22a restriction end piece 15 of lever 22, thus make latch bolt 4 be in its so-called inactive state.Door lock returns to state shown in Figure 1.
The following describes when the inclined-plane of head 11 not during correct side, how to make latch bolt 4 around A axle Rotate 180 ° at the door leaf that door lock is housed.
As shown in Figure 3, when user's actuating doors handle, when making in the complete retraction lock housings 1 of head 11, stopping means 24 no longer is subjected to the stopping of projection 22c of lever 22.If the user inserts a proper tools from the hole 26 of panel 3,, as shown in Figure 4, can make stopping means 24 slide to the upper end of groove 25 as screwdriver or T staple.In order to make stopping means 24 rest on its non-moving position, that is stopping means 24 is when being placed in the upper end of groove 25, and the user must unclamp door handle, so that the projection 22c of lever 22 and described groove 25 are overlapping, thereby stopping means 24 is blocked on its non-moving position, as shown in Figure 5.As a kind of selection, groove 25 allows stopping means 24 to rest on its upper end position.
When the user unclamped door handle, spring 20 discharged, and causes that driven member 5 counterclockwise rotates around the B axle.Simultaneously, described latch bolt 4 moves horizontally towards panel 3 spring 17 is discharged.End piece 15 also along with moving, causes that lever 22 counterclockwise rotates around the B axle.Because no longer limited device 24 constraints of the projection 22c of lever 22, the angle that described lever 22 pivots is got back to the needed angle of resting position greater than lever, and promptly the angle θ between the arm of the axle of shank 12 and lever 22 is greater than 90 °.The limited device 24 of last projection 22a of lever 22 stops, make that the projection 22c and the groove 25 of lever 22 are overlapping, cause stopping means 24 to be blocked in non-moving position like this, latch bolt 4 moves horizontally towards panel 3 directions, stretch out fully in lock housing 1 up to head 11, as shown in Figure 5.On the other hand, under this state of door lock, end piece 15 is arranged in two the relative holes 16 on two big vertical planes on the lock housing 1, and this allows end piece 15 can be around A axle Rotate 180 °.
Now, according to Fig. 6 we to describe frame for movement be how to be returned to original position.In the described state of Fig. 5, stopping means 24 is limited in non-moving position by the projection 22c of lever 22.When user's clockwise direction revolving door handle, driven member 5 turns clockwise around the B axle, thereby lever 22 is along with driven member 5 turns clockwise around same axle.This makes the projection 22c on the lever 22 separate with stopping means 24.As shown in Figure 6, if the user as screwdriver or T staple, can make stopping means 24 slide to the lower end of groove 25 by inserting a proper tools in the hole 26 on the panel 3.Also possibility stopping means 24 is got back to its so-called moving position under the effect of gravity.Door lock returns to state shown in Figure 3.
Still be unkitted as door lock and cross the threshold, by rotation lock housing 1, under the effect of gravity, stopping means 24 also can move between moving position and non-moving position in groove 25.
The lock out action of dead bolt 6 is described now.Lock out action is from situation shown in Figure 1, and at this moment, door lock is in unlocked state, and dead bolt 6 is fully retracted in the lock housing 1, and the user inserts its key in the lock tube 8 of locking lock barrel, with key counter clockwise direction rotation lock tube 8.Key bit 8a acts on the bottom of tablet 37, promotes tablet 37 to the translation of the top of lock housing 1, thereby it is removed from the top zigzag thing 35 of latch handle 32, and the projection 37a of tablet 37 is engaged in the zigzag thing 35.Simultaneously, key bit 8a will be between preceding two of following zigzag thing 35 of latch handle 32.Latch handle 32 will move horizontally towards panel 3 directions, and its displacement equals the distance of 35 of two zigzag things of latch handle 32.When the user continued to be rotated counterclockwise key, the zigzag thing 35 of key bit 8a and latch handle 32 and tablet 37 broke away from, and projection 37a is meshed with the zigzag thing 35 of latch handle 32 once more.Door lock was in single twist lock and decided state this moment.Must be noted that door lock never locks state to single twist lock and decides state, lock tube 8 has rotated 360 ° around its axis of rotation.Decide state from single twist lock, the user inserts key in the lock tube 8 of lock barrel, and with key rotation lock tube 8 counterclockwise, door lock will with to be not locked to single twist lock and decide the similar mode of state and enter into pair twist locks and decide state.
The process of unblanking of dead bolt 6 is similar to the locking process action.In this process, key bit 8a drives control lever 23, and its top to lock housing 1 is moved.Control lever 23 mobile causes lever 22 around the rotation of B axle clockwise direction, drives latch bolt and moves horizontally in head 11 is withdrawn lock housing 1 fully on the direction of panel 3 dorsad.Recess 28a and 28b allow the rotation of lever 22 clockwise directions and do not drive driven member 5.
In another preferred embodiment as shown in Figure 7, multi-point lock comprises a control member 7 that is connected with the control connector, is used for moving at least one the secondary locking latch (not shown) that is contained in the auxiliary lock housing (not shown).Door lock comprises a rotary body 9, this rotary body one side and 6 one-tenth driving relationship of dead bolt, and 7 one-tenth driving relationship of control member allow to come control member by described key on the other hand, and this point will be described in the back.
Dead bolt handle 132 has a projection 132a, the top edge vertical connection of this projection and dead bolt handle 132, and have a protuberance 133 in the chamber that can be bonded on rotary body 9.
Though invention has been described in conjunction with several specific embodiments,, the present invention obviously is not limited thereto, and it comprises all technical characterictics and their combination (if it entered protection scope of the present invention) same with said apparatus.
