BACKGROUND OF THE INVENTION
1. Fields of the invention
[0001] The present invention relates to a double sided lock, and more particularly, to a
transmission structure for a double sided lock so that the lock can be opened when
one end accepts a key and rotated.
2. Descriptions of Related Art
[0002] The conventional double sided lock is designed to be operated form either one of
two ends thereof, which means that when a key is inserted into the lock and rotates,
the lock cannot be unlocked from the other end of the lock. When one key is inserted,
the driving member is pushed to the cam of the lock so that the cam is rotated when
the key is rotated. In the meanwhile, the driving member is pushed by the key and
covers the other core at the end of the cam. The key cannot be removed when the core
is rotated, so that the other key cannot drive the driving member and cannot be inserted
into the lock from the other end of the lock. However, when the lock is used in a
hospital, a kindergarten, a senior center or the like, if the people inside the room
insert the key from inside and rotate the key, the staff cannot unlock the lock from
outside. This is dangerous when in emergency. Even if the staff break the lock, a
new lock has to be purchased and this costs a lot.
[0003] Another conventional double sided lock includes a driving member located between
the two cores, and the driving member has a first transmission member and a second
transmission member. A spring is located between the first and second transmission
members. Each of the first transmission member and the second transmission member
has a hole and an eccentric notch. The first and second pins are respectively installed
in the first transmission member and the second transmission member via the eccentric
notches. The first and second pins are connected to each other via the two respective
holes of the first and second transmission members. A spring is located between the
first and second transmission members, and another spring is located between the first
and second pins. The driving member is made by metal. Two respective keys are allowed
to be respectively inserted into the first and second cores to drive the first and
second transmission members and the first and second pins to unlock the lock.
[0004] However, notch and the reception space of the meal driving member has to be machined
one by one in a small area, so that the manufacturing deficiencies are often occurred.
Besides, because the notches are eccentric, so that when assembling, the first and
second pins have to be installed at an angle. This action may cause deformation to
the first and second pins. Furthermore, the first and second pins are Y-shaped pins
which are easily deformed and worn. Therefore, the conventional double sided lock
is difficult manufactured and assembled.
[0005] The present invention intends to provide a transmission structure of a double sided
lock to eliminate the shortcomings mentioned above.
[0006] Chinese patent application
CN 201802141 U discloses a transmission structure as defined in the preamble of claim 1. The European
patent application
EP 1 013 854 A1 discloses another type of transmission structure for a double sided lock.
SUMMARY OF THE INVENTION
[0007] The present invention relates to a transmission structure for a double sided lock
according to claim 1. The transmission structure comprises two driving members between
which a gap is formed. Each of the two driving members has an axis and a protrusion
extending radially from the outer periphery thereof. A resilient member is located
between the two driving members. Each of the two driving members has a hole defined
centrally therethrough, and each of the holes of the two driving members has a stop.
A first transmission unit has a shank extending from one end thereof. The shank extends
through the holes of the two driving members. A first spring is located between the
first transmission unit and the stop of one of the two driving members. A second transmission
unit has a tubular portion extending from one end thereof. The tubular portion extends
through the holes of the two driving members. The shank is movably inserted in the
tubular portion. The shank and the tubular portion are independent to each other.
A second spring is located between the second transmission unit and the stop of the
other one of the two driving members. The shank has a restriction member, and the
tubular portion has a restriction portion defined therein which restricts the restriction
member from disengaging from the tubular portion.
[0008] The transmission structure is characterized in that each of the holes of the two
driving members has a slot defined axially therein, the first transmission unit has
a first tab extending therefrom which is located corresponding to the slot corresponding
thereto, the second transmission unit has a second tab extending therefrom which is
located corresponding to the slot corresponding thereto.
[0009] Preferably, the resilient member has a resilient coefficient that is smaller than
that of each of the first and second springs.
[0010] Preferably, each of the two driving members has a groove defined in one side thereof.
The two ends of the resilient member are engaged with the grooves of the two driving
members.
[0011] Preferably, the two driving members are identical.
[0012] The present invention also relates to a double side lock comprising the transmission
structure as defined above, further comprising a cam which has a through hole. A passive
member is located on the inner periphery of the through hole and located corresponding
to the two driving members. The passive member has a recess defined radially therein
which is sized to allow the two driving members to pass. Two cores are respectively
connected to two sides of the cam and drive the two driving members respectively.
The two driving members are located corresponding to the through hole of the cam.
A space is defined between the two cores. The two driving members are movably located
in the space. When one of the two driving members is moved toward the core corresponding
thereto, the protrusion of the driving member moved toward the core is removed from
the recess, and the protrusion of the driving member not moved toward the core is
located in the recess. When the two protrusions of the two driving members are located
corresponding to the recess, and when the two driving members are applied by a force,
the resilient member is compressed, and the two protrusions of the two driving members
are located in the recess.
[0013] Preferably, the two cores each have a reception room, and each of the reception room
has a notch defined in the inside thereof. The notches are located corresponding to
the protrusions.
[0014] Preferably, the two cores are identical or different from each other.
[0015] Preferably, when at least one key is inserted into one of the cores, the distal end
of the at least one key contacts against the first transmission unit or the second
transmission unit.
[0016] Preferably, the two cores are inserted in a cylindrical portion from two ends of
the cylindrical portion of a housing. The cylindrical portion has an opened section
in which the cam is engaged. The cam is located between the two cores.
[0017] Preferably, two clips are located at two ends of the opened section so as to position
the two cores to the cylindrical portion.
[0018] The present invention has the following features.
[0019] When one key is inserted into one of the cores, the driving member is pushed to the
other core, and the protrusion of the driving member at the distal end of the key
is able drive the cam. The other driving member is disengaged from the recess and
cannot rotate the cam. When the other key is inserted into the other core, the first
and second springs between the first and second transmission units are compressed
so that said the other core can be rotated by said the other key until said the other
driving member is located corresponding to the recess. The resilient member between
the two driving members is compressed so that the two protrusions are located in the
recess such that the two cores can be rotated independently.
[0020] The first and second transmission units are located along the axis to connect the
shank and the tubular portion, the assembling steps are easy to shorten the assembling
time. The driving members, and the first and second transmission units are conveniently
manufactured without extra machining steps. The two driving members are identical
so that the manufacturing cost is reduced. The shank and the tubular portion are easily
connected to each other without worry of damage during assembling.
[0021] Thanks to the slots of the driving members and the first and second tabs of the first
and second transmission units, the distal end of the key cannot interfere the movement
of the first and second transmission units. The driving members of the present invention
can be cooperated with cores with different angles of keyholes. Therefore, the present
invention does not have to be made according to the different directions of the keyholes
to reduce the manufacturing cost.
[0022] The present invention will become more obvious from the following description when
taken in connection with the accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0024] Referring to Figs. 1 to 3, the transmission structure of the present invention comprises
two driving members 1a, 1b which are identical, and a gap L is formed between the
two driving members 1a, 1b. Each of the two driving members 1a, 1b has an axis A,
and a protrusion 11a/11b extends radially from the outer periphery of each of the
two driving members 1a, 1b. A resilient member 2 is located between the two driving
members 1a, 1b. Each of the two driving members 1a, 1b has a groove 12 defined in
one side thereof, the two ends of the resilient member 2 are engaged with the grooves
12 of the two driving members 1a, 1b.
[0025] Each of the two driving members 1a, 1b has a hole 13a/13b defined centrally therethrough.
Each of the holes 13a, 13b of the two driving members 1a, 1b has a stop 131a, 131b.
Each of the holes 13a, 13b of the two driving members 1a, 1b has a slot 132a/132b
defined axially in the inner periphery of the hole 13a/13b.
[0026] A first transmission unit 3 has a shank 31 extending from one end thereof and the
shank 31 extends through the holes 13a, 13b of the two driving members 1a, 1b along
the axis A. A first spring 4 located between the first transmission unit 3 and the
stop 131a of the driving member 1a. The first transmission unit 3 has a first tab
32 extending therefrom which is located corresponding to the slot 132a corresponding
thereto.
[0027] A second transmission unit 5 has a tubular portion 51 extending from one end thereof.
The tubular portion 51 extends through the holes 13a, 13b of the two driving members
1a, 1b along the axis A. The shank 31 is movably inserted in the tubular portion 51.
The shank 31 and the tubular portion 51 are independent to each other so that the
shank 31 cannot drive the tubular portion 51. A second spring 6 located between the
second transmission unit 5 and the stop 131b of the driving member 1b. The second
transmission unit 5 has a second tab 52 extending therefrom which is located corresponding
to the slot 132b corresponding thereto.
[0028] The shank 31 has a restriction member 311, and the tubular portion 51 has a restriction
portion 511 defined therein which restricts the restriction member 311 from disengaging
from the tubular portion 51. Therefore, the first and second transmission units 3,
5 are not separated from each other by the force from the first and second springs
4, 6. The resilient member 2 has a resilient coefficient that is smaller than that
of each of the first and second springs 4, 6.
[0029] It is noted that as shown in Fig. 3, the first transmission unit 3 is located at
the driving member 1a at the left side, and the second transmission unit 5 is located
at the driving member 1b at the right side, however, the present invention is not
limited to this arrangement. The first transmission unit 3 may also be located at
the driving member 1b at the right side, and the second transmission unit 5 is located
at the driving member 1a at the left side.
[0030] A cam 7 has a through hole 71 and a passive member 72 is located on the inner periphery
of the through hole 71 and located corresponding to the two driving members 1a, 1b.
The passive member 72 has a recess 73 defined radially therein which is sized to allow
the two driving members 1a, 1b to pass.
[0031] Two cores 8a, 8b are respectively connected to two sides of the cam 7 and drive the
two driving members 1a, 1b respectively which are located corresponding to the through
hole 71 of the cam 7. A space 81 is defined between the two cores 8a, 8b, the two
driving members 1a, 1b are movably located in the space 81. The two cores 8a, 8b are
identical or different from each other. The two cores 8a, 8b each have a reception
room 82a/82b, each of the reception room 82a, 82b has a notch 83a/83b defined in the
inside thereof. The notches 83a, 83b are located corresponding to the protrusions
11a, 11b.
[0032] A housing 9 has a cylindrical portion 91, and the two cores 8a, 8b inserted in the
cylindrical portion 91 from two ends of the cylindrical portion 91. The cylindrical
portion 91 has an opened section 92 in which the cam 7 is engaged, wherein the cam
7 is located between the two cores 8a, 8b. Two clips 93 are located at two ends of
the opened section 92 so as to position the two cores 8a, 8b to the cylindrical portion
91.
[0033] As shown in Fig. 4, when a key 84a is inserted into the core 8a at the left side
of the lock, the key 84a extends through the core 84a and the distal end of the key
84a pushes the first transmission unit 3 in the space 81. The first transmission unit
3 is biased by the first spring 4 and contacts the stop 131a of the driving member
1a. The force from the first spring 4 is larger than the friction between the two
driving members 1a, 1b and the two cores 8a, 8b, so that the two driving members 1a,
1b are pushed toward the right hand side of the space 81 to move the driving member
1b toward the core 8b. Preferably, the driving member 1b firmly contacts the wall
of the reception room 82b of the core 8b so as to remove the protrusion 11b of the
driving member 1b from the recess 73 of the cam 7, while the protrusion 11a of the
driving member 1a is located in the recess 73 of the cam 7. Assume that the key 84a
is rotated to rotate the core 8a, the protrusion 11a is moved via the notch 83a and
drives the cam 7, and the slot 132a of the driving 1a also rotates the first transmission
unit 3.
[0034] On the contrary, as shown in Fig. 5, when a key 84b is inserted into the core 8b
at the right side of the lock, the key 84b pushes the second transmission unit 5 which
is biased by the second spring 6 and contacts the stop 131b of the driving member
1b. The driving members 1a, 1b are moved toward the left hand side of the space 81,
and the driving member 1a firmly contacts the wall of the reception room 82a of the
core 8a so as to remove the protrusion 11a of the driving member 1a from the recess
73 of the cam 7, while the protrusion 11b of the driving member 1b is located in the
recess 73 of the cam 7. Therefore, the key 84b can rotate to rotate the core 8b to
unlock the lock.
[0035] As shown in Fig. 6, if the cam 7 is not rotated, and the protrusions 11a, 11b are
located corresponding to the recess 73 of the cam 7. When both of the two keys 84a,
84b are inserted into the cores 8a, 8b, then the first and second transmission units
3, 5 are pushed by the two respective distal ends of the two keys 84a, 84b. However,
the first and second springs 4, 6 are slightly compressed, and the resilient member
2 is compressed larger than the first and second springs 4, 6, therefore, the two
driving 1members 1a, 1b move toward each other to narrow the gap L, the two protrusions
11a, 11b are both located in the recess 73. When the two keys 84a, 84b are rotated,
the two cores 8a, 8b, and the two driving members 1a, 1b are co-rotated, and the lock
is unlocked.
[0036] As shown in Fig. 7, if the user inserts the key 84a in the core 8a and rotates the
core 8a, the cam 7 is rotated. Because the shank 31 and the tubular portion 51 are
independent to each other, so that the when the first transmission unit 3 is rotated,
the second transmission unit 5 remains still, therefore, the driving member 1b is
located at the initial position. The recess 73 of the cam 7 is not located corresponding
to the protrusion 11b of the driving member 1b. When the key 84b is inserted in the
core 8b, as shown in Fig. 8, the distal end of the key 84b contacts the second transmission
unit 5. Although the resilient member 2 is compressed, the protrusion 11b of the driving
member 1b is not located corresponding to the recess 73 of the cam 7, so that the
protrusion 11b can only contacts the sidewall of the passive member 72. The second
spring 6 is compressed, the tubular portion 51 of the second transmission unit 5 moves
toward the shank 31 of the first transmission unit 3, so that the key 84b can be inserted
in the core 8b and rotate the core 8b. During the rotation of the key 84b in the core
8b, the protrusion 11b still contacts the sidewall of the passive member 72 until
when the protrusion 11b is located corresponding to the recess 73 of the cam 7 as
shown in Fig. 9. As mentioned before, the resilient coefficient of the resilient member
2 is smaller than those of the first and second springs 4, 6, so that the second spring
6 partially returns, and the resilient member 2 is compressed to allow the protrusion
11b to be located in the recess 73. At this moment, both of the protrusions 11a, 11b
are located in the recess 73, The cores 8a, 8b and the driving members 1a, 1b can
be rotated by using the keys 84a, 84b.
[0037] As shown in Fig. 5, if the key 84b is first inserted in the core 8b, and the key
84a is then inserted in the core 8a later, the protrusion 11a contacts the sidewall
of the passive member 72, and the first spring 4 is compressed. The shank 31 of the
first transmission unit 3 moves toward the tubular portion 51 of the second transmission
unit 5 until the protrusion 11a to be located in the recess 73 as shown in Fig. 9.
The first spring 4 partially returns, and the resilient member 2 is compressed to
allow the protrusions 11a, 11b to be located in the recess 73. Both of the keys 84a,
84b can rotate to drive the cam to unlock the lock.
[0038] It is noted that the distal end of each key 84a/84b has an inclined portion which
is located at the center of the cores 8a, 8b, so that the slots 132a, 132b of the
driving members 1a, 1b, the first tab 32 and the second tab 52 are designed to prevent
the interference from the distal ends of the keys 84a, 84b. The slots 132a, 132b of
the driving members 1a, 1b, the first tab 32 and the second tab 52 are located corresponding
to the keyhole, so that when the distal ends of the keys 84a, 84b push the first and
second transmission units 3, 5, the keys 84a, 84b actually contact the first and second
tabs 32, 52 to prevent the keys 84a, 84b from interfering the movement of the first
and second transmission units 3, 5. Besides, the keyholes of the cores 8a, 8b are
not restricted to be upright, the keyholes of the cores 8a, 8b oriented toward any
angle can be cooperated with the present invention, simply installing the driving
members 1a, 1b corresponding to the directions of the keyholes. The driving members
1a, 1b and the first and second transmission units 3, 5 do not need to be individually
manufactured along with the different orientation of the keyholes.
[0039] While we have shown and described the embodiment in accordance with the present invention,
it should be clear to those skilled in the art that further embodiments may be made
without departing from the scope of the present invention, as defined by the appended
