Detailed description of the invention

With reference to drawing, indicated by 1 as entirety according to the embodiment of the lock of the present invention.Lock 1 includes presenting the metal of the shape of tetragon box body and supports housing 2, and it has the end rear wall 2a, upper end wall 2b and lower end wall 2c and opposite sidewall 2d, 2e.This housing is closed by cap seal, its inner body being partly cut away and/or removing to illustrate lock in drawing.

According to routine techniques, lock includes door bolt 3, door bolt 3 comprises two or more locking pins 3a and is slidably mounted in the inherent inoperative position of housing and between the position of locking door, selling in 3a indentation housing in inoperative position, pin 3a draws from the sidewall 2d of housing 2 in for the position of locking door.Except door bolt 3, this lock includes the plate 4 for actuating auxiliary door bolt (not shown), plate 4 can vertically be slidably mounted in housing, and has the upper end 4a and bottom 4b that draw respectively from the opening formed among the upper end wall 2b and lower end wall 2c of housing 2.Plate 4 is operatively connected to door bolt 3 by such form: when fastening 3 with a bolt or latch and moving to its withdrawn position from its retracted position, and plate 4 is mobile to lifting position (raisedposition) from down position (loweredposition).This mechanical driving device being made by comprising oscillating deck 5 (visible in Fig. 3) and obtain, oscillating deck 5 swings installation around the axle 6 supported on housing of lock, and is operatively respectively connecting to plate 4 by eyelet coupling (pin-slitcoupling) 7,8 and is connected to door bolt 3.Due to above-described layout, the vertically mobile of plate 4 determines the plate 5 rotation around its axle 6, and moving horizontally of door bolt 3 occurs therewith.According to routine techniques, end 4a, 4b of plate 4 is configured to attach to other door bolt frame for movement, these door bolt Design of Mechanical Structures become above and below the lock that illustrates in this article in two other region of arrangement separated by a distance by door locking in off position under.

Being provided with helical spring 9 in housing, it is operatively placed between the wall 2c of plate 4 and housing, and tends to promoting plate 4 towards the position rising, locking.Spring catch (pinspring) 10 plays similar effect, spring catch 10 is arranged on the adjacent place of spring 9 and is operatively placed between housing and the pin 10a fixing relative to door bolt 3, to tend to promoting door bolt 3 towards its withdrawn position being used for locking door.

According to equally substantially conventional technology, door bolt 3 and plate 4 usually remain in its retracted position, and the reserved unit by being made up of the bending section 11 (Figure 1A) of rocking lever 12 (Fig. 2 B) resists the effect of spring 9,10 in the shown example.The bending section 11 of lever 12 is designed to engage with brake area 400 (Figure 1A), and brake area 400 is formed on the edge of the forming openings 40 in being arranged on plate 4.When plate 12 is in Figure 1A in illustrated position, plate 4 is locked in its down position to resist the effect of spring 9, due to the connection of oscillating deck 5 composition, therefore which dictates that door bolt 3 is retained in its retracted position.

According to equally substantially conventional technology, lock according to the present invention is provided with exploring block 14, and exploring block 14 is slidably mounted in and supports in housing, is located therein exploring block 14 from withdrawn position (Figure 1A) prominent for the sidewall 2d of housing with wherein between the position in exploring block 14 indentation housing.That be associated with exploring block 14 is helical spring 14a, its by parts 14 towards withdrawn position return.

When the door closes, owing to the framework of door is not envisioned with any recess in exploring block location, exploring block 14 pressure is return in the housing of lock.The frame for movement of lock makes the indentation of exploring block 14 cause reserved unit 11 to return from its position (reserved unit 11 is bonded on connecting plate 4 this position), so that plate 4 buckles into its lifting position due to spring 9, door bolt 3 is so also made to fasten towards withdrawn position.For this purpose, exploring block is operatively connected to reserved unit 11 by the mechanical driving device comprising plate 15, and plate 15 swings installation around the axle 16 of pin 17, and pin 17 engages with the groove 15a of plate 15 slidably.Due to aforesaid layout, plate 15 can (flatly, observed in the figure) slip point-blank relative to pin 17, can swing around pin self again.

When automatic fastening function is effective, lever 15 is in angle position illustrated in Figure 1A.In this state, the closedown of door the indentation (see Fig. 2 A) of the exploring block 14 caused makes exploring block engage against the surface 150 of lever 15 so that the latter moves horizontally (see Fig. 2 A) relative to pin 17.After the aforementioned sliding motion of lever 15, lever 15 position that the bending section 11 of lever 12 is departed from by the pin 151 supported towards the surface 400 of the opening 40 from plate 4 promotes.Therefore, lever 12 and reserved unit 11 move to the position shown in Fig. 3, and plate 4 can buckle into Fig. 3 in illustrated lifting position under the promotion of spring 9.Meanwhile, door bolt 3 is promoted (see Fig. 3) towards its withdrawn position by oscillating deck 5 and spring 10.

Arrive this, it has been described that the conventional operation of the lock when automatic fastening function is effective.

As having already mentioned above, contemplate the device for making automatic fastening function disable according to the lock of the present invention.For this purpose, including the control parts 21 (such as seeing Fig. 1 C) being made up of lobe plate 21 according to the lock of the present invention, lobe plate 21 swings around the axle 22 in the sidewall 2d of lock and installs, and is provided with the knob (knob) 20 of cylinder.The arched seam 21a that knob 20 is passed through in wall 2d and is formed is prominent on the outside of housing 2, which defines the two of plate 21 end position.Plate 21 plays the effect of cam part, for controlling to promote the position (see Figure 1A and Fig. 1 C) of plate 23, it is adjacent with the inner surface of the wall 2d of the housing of lock, and is bonded in the seam 25 of formation in plate 23 directed (Fig. 1 C) slidably relative to aforesaid wall 2d by the pin 24 of the wall 2d by being fixed to housing.

Plate 23 includes being designed to the bent projection portion 230 that the end 152 with lever 15 contacts.

(illustrating in Fig. 1 to Fig. 3) when knob 20 is in its down position, plate 23 is necessarily in its extreme lower position so that the automatic fastening function of lock is effective.It is true that in this state, when the door closes, exploring block 14 is retracted in the housing of lock, and engage with the surface 150 of lever 15, so that this lever level is slided, and occur reserved unit 11 to depart from therewith and plate 4 and door bolt 3 buckle into it in the position of locking door.Contrary when knob 20 is brought in its lifting position (in Fig. 4 A, Fig. 4 B and Fig. 5 diagram), plate 23 moves up, and makes plate 15 rotate the effect of opposing spring catch 170 around pin 17.As visible in Figure 4 A, the cam contour of oscillating deck 21 shapes by this way: in the lifting position of knob 20, the nose 210 contacted with plate 23 in plate 21 has exceeded dead point (dead-centre) position so that tend to making the spring 170 that lever 15 and plate 23 return downwards self cause that plate 21 is locked in new lifting position.

As visible in Fig. 4 B and Fig. 5, in the aforementioned lifting position of plate 15, the latter is beyond the effective range of exploring block 14 so that exploring block 14 is retracted in the housing of lock 2 when the door closes, but when do not have any engage against lever 15 aforesaid movement do not work.So, when this automatic fastening function lost efficacy, when the door closes, door bolt 3 and plate 4 will not buckle into automatically to in the position of locking door.
