The specific embodiment

Fig. 1 illustrates the component parts of the cylindrical lock set including the inside part 1 and exterior portion 2.The inside part 1 and exterior portion 2 interact with snap assembly 3, and when these parts are installed in door-plate 4, the inside part 1 engages with snap assembly 3.The inside part 1 is usually located at door-plate 4 inner sides, and exterior portion 2 is positioned at door-plate 4 outsides, and two parts are connected by a pair of hold-down screw (not shown).

The inside part 1 comprises base 5, for being positioned in the cylindrical hole 6 forming through door-plate 4 surfaces.Snap assembly 3 is positioned at the chamber 7 of extending from door-plate 4 edges.Chamber has the axis X X crossing with the axis YY in hole 6.Cylindrical hole and axis X X make cylindrical locking device and distinguish such as the other forms of lock set of latch lock (rimlocks) and mortice lock (morticelocks) with respect to the directed combination of YY.

It should be pointed out that the inside part 1 is rotated 1/4th on Z in the clockwise direction, so that demonstration base 5 is accommodated shuttle 9.Shuttle 9 can be in the interior movement of base 5 when handle 10 rotates.Base 5 is rotatably positioned in hole 6, thereby makes the movement of shuttle 9 in fact consistent with axis X X.Snap assembly 3 is included in the shell 11 engaging with base 5 while being mounted.Shuttle 9 engages with foot piece 8, thereby is retracted into base 5 when interior at shuttle 9, in the lock bolt 2 retraction shells 11 of snap assembly 3.

Because Fig. 1 illustrates the cylindrical lock set that comprises handle 10, the operation of handle 10 can be hindered with respect to the position of lock stile (lockstile) or architrave (architrave) (not shown) by handle 10.More particularly, at the inner surface of door 4, with respect to architrave depression, compared with the situation of aliging with architrave with the inner surface of door 4, the operation of handle 10 is more likely hindered.Especially user may find to be difficult to key is arranged in lock core 13 or rotary handle 10.Under these situations, user has the right to choose of the backset of snap assembly being adjusted to longer backset or extending backset.The adjustment of the backset to snap assembly according to the preferred embodiment of the invention will be described below.

With reference now to Fig. 2,, the figure illustrates a part for snap assembly 3, its housing 11 is removed.This figure has disclosed snap 12 and has been connected to by pin 18 (seeing the pin in Fig. 3) head end 14 of pull bar 15.Snap assembly also comprises foot piece 8, and this foot piece 8 has the tail end 16 that is in use connected to shuttle 9.Importantly, foot piece 8 is not directly connected to lock bolt 12 by pin 18, but indirectly by locking key 17, is connected to pull bar 15.This is connected in figure below and is shown by clearer.

Fig. 3 illustrates locking key 17, and this locking key 17 comprises that acceptance pin 18 is to fix the hole 19 of locking key 17 with respect to the axial location XX of pull bar 15.Should be appreciated that locking key 17 needs not to be the element separation with pull bar 15.More particularly, pull bar 15 can be configured to releasably steady brace 15 with respect to the axial location XX of foot piece 17.

Illustrated locking key 17 comprises the protuberance (lug) 20 being formed on arm 21.When locking key 17 is during in moving position, protuberance 20 is arranged in the first recess 22 that is formed on foot piece 8, as shown in Figure 3.In order to adjust the axial location XX of foot piece 8 with respect to pull bar 15, need to as shown in Fig. 4, locking key 17 be moved to inactive state.

Fig. 4 illustrates for the outstanding crossover tool 23 in hole 24 through being formed in foot piece 8.This permission instrument 23 protuberance 20 that engages with locking key 17 and move up in the side that is approximately perpendicular to axial XX.Because this function can be realized by other forms of instrument 23, the form of illustrated tool 23 clearly not necessarily.

As can be seen from Figure 5, this transverse movement makes protuberance 20 depart from the first recess 22 being formed in foot piece 8.Foot piece 8 can be axially moving on XX, as shown in Fig. 5 or 6.

Locking key 17 also comprises the seam 25 that holds the guiding piece 26 being associated with foot piece 8.The layout of this guiding piece 26 and seam 25 has limited foot piece 8 movement in the axial direction by stitching 25 length.When comparison diagram 7 and 8, can notice, when foot piece 8 moves with respect to pull bar 15, guiding piece 26 comes and goes (shunts) in seam 25.

Fig. 7 illustrates has a pair of arm 27a, the foot piece 8 of b, and these arms 27a, b is limited to the seam 28 between them.Pin 18 run through seam 28 extend and with arm 27 and locking key 17 at least one interact so that by the mobile restriction of foot piece 8 at axial XX.Although illustrate two arms 27, same effect also can be realized by single arm.

Fig. 8 has shown that arm 21 that protuberance 20 is located thereon can elastic buckling, thereby when foot piece 8 arrives illustrated extended position, protuberance 20 is pulled to and is arranged in the second recess 29 that is formed on foot piece 8, as shown in Figure 9.

With reference now to diagram, Figure 10 of the foot piece 8 extending with respect to pull bar 15.Housing 30 is introduced into surround at least a portion foot piece 8.Housing 30 has the upwardly extending end surface 31 in the footpath with respect to axis X X.It is porose 32 that end surface 31 forms, to allow the tail end 16 of foot piece 8 to pass therefrom.Hole 32 is configured to allow tail end 16 only at one or two position of rotation, to pass therefrom.But at other position of rotation, hole 32 does not allow foot piece 8 to pass therefrom.

Figure 10 illustrates housing 30 at a position of rotation.Once foot piece 8 is through hole 32, housing 30 is just rotated 1/4th weeks and arrives the orientation shown in Figure 11.Illustrated housing 30 comprises a pair of protruding 33, and this is fitted in the recesses 34 that form in shell 11 easily to projection 33.This just joint is not clearly unique possible form.For example, housing 30 can with shell 11 frictional fit, or be even threaded onto shell 11.

From Figure 11, should also be noted that shell 11 and housing 30 include the arm 35 of the base 9 for engaging cylindrical lock set.Certainly, when snap assembly 3 operates with short backset pattern, the arm 35 of shell 11 engages base 9, and when snap assembly 3 operates with long backset pattern, the arm 35 of housing 30 engages base 9.

Figure 12 illustrates the housing 30 being fitted on shell 11, and can notice, housing 30 has the diameter identical with shell 11.This is placed in standard size chamber 7 snap assembly 3 nattily, and no matter snap assembly 3 is with short backset pattern or long backset pattern operation.

Should be appreciated that from the foregoing description and the invention provides the snap assembly 3 of relatively simply adjusting between short backset operator scheme and the backset operator scheme of length.The housing 30 with shell 11 with same diameter further has the following advantages, and allows snap assembly to be fitted to nattily in chamber 7 and no matter whether it operates under short backset pattern or long backset pattern.

Various distortion and/or additional can be introduced into foregoing latch assembly, and do not depart from the spirit or scope of the present invention.
