The seat board (46) is securely connected to the inside mounting seat (41) to cover the middle board (45) and the linking device (44) between the inside mounting seat (41) and the seat board (46), abuts the supporting rods (133, 22) of the transmitting device (13) and the cylinder (20) and has a length, a lower end, an upper end, a spring hole (461), a middle locating hole (462), an upper locating hole (463) and multiple through holes (464). The length of the seat board (46) is longer than the length of the middle board (45). The spring hole (461) is formed through the seat board (46) near the lower end and aligns with the lower guiding hole (451) of the middle board (45). The middle locating hole (462) is formed through the seat board (46), aligns with the middle guiding hole (452) of the middle board (45) and is mounted around the orientating shaft (442). The upper locating hole (463) is formed through the seat board (46) and aligns with the upper guiding hole (453) of the middle board (45). The through holes (464) are formed through the seat board (46) and are respectively align with the supporting rods (133, 22) of the transmitting device (13) and the cylinder (20).
The inside reset spring (47) is connected to the seat board (46) in the spring hole (461) and has a center and a driving shaft (471). The driving shaft (471) is square, is mounted through the center of the inside reset spring (47) and the driving square-hole (4411) of the lower rotating button (441) and is securely connected to the shaft hole (422) of the operating handle (42).
The switch mount (48) is rotatably mounted between the upper guiding hole (453) of the middle board (45) and the upper locating hole (463) of the seat board (46) and has an outer end and an inner end. The outer end of the switch mount (48) is mounted around the cylinder-transmitting panel (21) of the cylinder (20). The inner end of the switch mount (48) is mounted around the connecting post (431) of the switch (43). When a user rotates the switch (43), the switch mount (48) and the cylinder-transmitting panel (21) will be rotated with the switch (43) in the same direction.
The fastening bolts (49) are mounted through the through holes (464) of the seat board (46) and are respectively and securely connected to the supporting rods (133, 22) of the transmitting device (13) and the cylinder (20) to hold the interior assembly (40) with the multi-point latch bar (30), the cylinder (20) and the exterior assembly (10).
With reference to Figs. 2 and 6, the multi-point latch (30) is mounted in the sidewall of the door and the exterior assembly (10) and the interior assembly (40) are respectively mounted on the outer side and the inner side of the door. The latch bolts (31) can be retracted into the multi-point latch (30) when the rotating hole (32) is rotated with the rotating spindle (16) so as to unlock the door.
A key can be inserted into the keyway of the cylinder (20) to lock the door by the cylinder-transmitting panel (21) rotating the panel hole (34) in clockwise direction to allow the dead bolt (33) moving out of the sidewall of the multi-point latch bar (30).
The rotating spindle (16) can be rotated relative to the multi-point latch (30) to unlock the door by pressing the press-button (12) of the exterior assembly (10) or pressing the operating stein (421) of the operating handle (42).
In addition, when pressing the operating stem (421) of the operating handle (42), the motion of the linking device (44) can make the cylinder-transmitting panel (21) rotating in a counterclockwise to allow the dead bolt (34) retracting into the multi-point latch (30) to unlock the door.
With reference to Figs. 2, 3, 7 and 8, when the user presses the press-button (12) of the exterior assembly (10), the driving surface (122) on the inner end of the press-button (12) will abut the abutting slab (141) to push the transmitting board (14) to move upward relative to the engaging wheel (15). As the transmitting board (14) moves upward with the inner end of the press-button (12), the engaging wheel (15) will rotate in a clockwise direction with the engagement between the rack (142) and the engaging teeth (153). Then, the rotating spindle (16) connected to the spindle hole (151) will be rotated by the engaging wheel (15) to let the latch bolts (31) retract into the multi-point latch (30) and unlock the door. When the user releases the press-button (12), the press-button (12) and the engaging wheel (15) can be returned to the original position by the outside reset spring (144) pushing the transmitting board (14) to move back the original location.
With reference to Figs. 3, 5 and 9, during the operating process of unlocking the door above-mentioned, the rotating spindle (16) is rotated in a clockwise direction, the tilting plate (163) will idle in the engaging holes (4421) of the orientating shaft (442). Then, the driving shaft (471) will not rotate with the linking device (44) due to the tilting plate (163) of the rotating spindle (16) being rotated in the engaging holes (4421) of the orientating shaft (442).
Therefore, this can prevent the inside reset spring (47) of the interior assembly (40) from being pressed when the rotating spindle (16) is rotated by the press-button (12). Consequently, useful life of the inside reset spring (31) of the interior assembly (40) will be prolonged.
When the switch (43) is rotated in a clockwise direction at an angle of 90 as shown in Figs. 5, 9 and 10, the linking device (44) and the switch mount (48) will rotate with the switch (43) to allow the cylinder-transmitting panel (21) rotating with the switch mount (48). Then, the panel hole (34) can be rotated with the cylinder-transmitting panel (21) to allow the dead bolt (33) to move out of the sidewall of the multi-point latch bar (30) to lock the door. During the operating process of locking the door above-mentioned, the upper wheel (445) of the linking device (44) will rotate with the connecting board (444) by the C-shaped groove (4442) to pull the rail board (446) moving upward relative to the limiting beams (448). Then, the lower wheels (447) of the limiting beams (448) will rotate to the lower end of the rail board (446).
With further reference to Figs. 4, 11 and 12, when pressing the operating stem (42 1) of the operating handle (42) to resist elastic force of the inside reset spring (47), the driving shaft (471) will be rotated in a clockwise direction with the shaft hole (442) of the operating handle (42) being securely mounted around the square driving shaft (471). The lower rotating button (441) will be rotated with the driving shaft (471) and the connecting beams (443) will be moved with the lower rotating button (441). Then, the orientating shaft (442) will be rotated with the movement of the connecting beams (443) and one of the limiting beams (448) will move downward relative to the rail board (446) and the other limiting beam (448) will move upward relative to the rail board (446). The connecting board (444) will be rotated in a counterclockwise direction due to the upper wheel (445) of the rail board (446) pulling the connecting board (444). As the connecting board (444) rotates with the rail board (446), the switch mount (48) will rotate with the connecting board (444) in a counterclockwise direction.
When the orientating shaft (442) is rotated in a clockwise direction, the orientating shaft (442) will rotate the tilting plate (163) by the engagement between the engaging holes (4421) and the tilting plate (163). The latch bolts (31) can be retracted into the multi-point latch (30) when the rotating spindle (16) is rotated with the tilting plate (163). In addition, the dead bolt (33) can be retracted into the multi-point latch (30) when the switch mount (48) is rotated with the switch (43) in a counterclockwise direction. Consequently, the latch bolts (31) and the dead bolt (33) can be retracted into the multi-point latch bar (30) at the same time as the operating stem (421) of the operating handle (42) is pressed downward. Then, user can unlock the door quickly in an urgent situation by pressing the operating stem (421) of the operating handle (42).

The outer end of the switch mount (48) is mounted around the cylinder-transmitting panel (21) of the cylinder (20). The inner end of the switch mount (48) is mounted around the connecting post (431) of the switch (43). When a user rotates the switch (43), the switch mount (48) and the cylinder-transmitting panel (21) will be rotated with the switch (43) in the same direction.
The fastening bolts (49) are mounted through the through holes (464) of the seat board (46) and are respectively and securely connected to the supporting rods (133, 22) of the transmitting device (13) and the cylinder (20) to hold the interior assembly (40) with the multi-point latch bar (30), the cylinder (20) and the exterior assembly (10).
With reference to Figs. 2 and 6, the multi-point latch (30) is mounted in the sidewall of the door and the exterior assembly (10) and the interior assembly (40) are respectively mounted on the outer side and the inner side of the door. The latch bolts (31) can be retracted into the multi-point latch (30) when the rotating hole (32) is rotated with the rotating spindle (16) so as to unlock the door.
A key can be inserted into the keyway of the cylinder (20) to lock the door by the cylinder-transmitting panel (21) rotating the panel hole (34) in clockwise direction to allow the dead bolt (33) moving out of the sidewall of the multi-point latch bar (30).
The rotating spindle (16) can be rotated relative to the multi-point latch (30) to unlock the door by pressing the press-button (12) of the exterior assembly (10) or pressing the operating stein (421) of the operating handle (42).
In addition, when pressing the operating stem (421) of the operating handle (42), the motion of the linking device (44) can make the cylinder-transmitting panel (21) rotating in a counterclockwise to allow the dead bolt (34) retracting into the multi-point latch (30) to unlock the door.
With reference to Figs. 2, 3, 7 and 8, when the user presses the press-button (12) of the exterior assembly (10), the driving surface (122) on the inner end of the press-button (12) will abut the abutting slab (141) to push the transmitting board (14) to move upward relative to the engaging wheel (15). As the transmitting board (14) moves upward with the inner end of the press-button (12), the engaging wheel (15) will rotate in a clockwise direction with the engagement between the rack (142) and the engaging teeth (153). Then, the rotating spindle (16) connected to the spindle hole (151) will be rotated by the engaging wheel (15) to let the latch bolts (31) retract into the multi-point latch (30) and unlock the door. When the user releases the press-button (12), the press-button (12) and the engaging wheel (15) can be returned to the original position by the outside reset spring (144) pushing the transmitting board (14) to move back the original location.
With reference to Figs. 3, 5 and 9, during the operating process of unlocking the door above-mentioned, the rotating spindle (16) is rotated in a clockwise direction, the tilting plate (163) will idle in the engaging holes (4421) of the orientating shaft (442). Then, the driving shaft (471) will not rotate with the linking device (44) due to the tilting plate (163) of the rotating spindle (16) being rotated in the engaging holes (4421) of the orientating shaft (442).
Therefore, this can prevent the inside reset spring (47) of the interior assembly (40) from being pressed when the rotating spindle (16) is rotated by the press-button (12). Consequently, useful life of the inside reset spring (31) of the interior assembly (40) will be prolonged.
When the switch (43) is rotated in a clockwise direction at an angle of 90 as shown in Figs. 5, 9 and 10, the linking device (44) and the switch mount (48) will rotate with the switch (43) to allow the cylinder-transmitting panel (21) rotating with the switch mount (48). Then, the panel hole (34) can be rotated with the cylinder-transmitting panel (21) to allow the dead bolt (33) to move out of the sidewall of the multi-point latch bar (30) to lock the door. During the operating process of locking the door above-mentioned, the upper wheel (445) of the linking device (44) will rotate with the connecting board (444) by the C-shaped groove (4442) to pull the rail board (446) moving upward relative to the limiting beams (448). Then, the lower wheels (447) of the limiting beams (448) will rotate to the lower end of the rail board (446).
With further reference to Figs. 4, 11 and 12, when pressing the operating stem (42 1) of the operating handle (42) to resist elastic force of the inside reset spring (47), the driving shaft (471) will be rotated in a clockwise direction with the shaft hole (442) of the operating handle (42) being securely mounted around the square driving shaft (471). The lower rotating button (441) will be rotated with the driving shaft (471) and the connecting beams (443) will be moved with the lower rotating button (441). Then, the orientating shaft (442) will be rotated with the movement of the connecting beams (443) and one of the limiting beams (448) will move downward relative to the rail board (446) and the other limiting beam (448) will move upward relative to the rail board (446). The connecting board (444) will be rotated in a counterclockwise direction due to the upper wheel (445) of the rail board (446) pulling the connecting board (444). As the connecting board (444) rotates with the rail board (446), the switch mount (48) will rotate with the connecting board (444) in a counterclockwise direction.
When the orientating shaft (442) is rotated in a clockwise direction, the orientating shaft (442) will rotate the tilting plate (163) by the engagement between the engaging holes (4421) and the tilting plate (163). The latch bolts (31) can be retracted into the multi-point latch (30) when the rotating spindle (16) is rotated with the tilting plate (163). In addition, the dead bolt (33) can be retracted into the multi-point latch (30) when the switch mount (48) is rotated with the switch (43) in a counterclockwise direction. Consequently, the latch bolts (31) and the dead bolt (33) can be retracted into the multi-point latch bar (30) at the same time as the operating stem (421) of the operating handle (42) is pressed downward. Then, user can unlock the door quickly in an urgent situation by pressing the operating stem (421) of the operating handle (42).
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and features of the invention, the disclosure is illustrative only.
Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
