The present invention relates to an adjustable baffle and a doorframe having the adjustable baffle, the adjustable baffle allows the door lock to be smoothly operated relative to the doorframe.
Generally, a door lock is installed to a door, and the doorframe includes a recess in which a baffle is installed, so that the door lock is inserted into or removed from the recess of the doorframe via the baffle to lock the door or to unlock the door.
The baffle installed to the doorframe includes a through hole which is located corresponding to the latch of the door lock. The latch of the door lock extends through the through hole of the baffle when the door is locked. The baffle prevents the door latch to hit or scratch the periphery of the recess of the doorframe.
The baffle usually is a single plate, and the through hole of the baffle is shaped to be compatible to the shaped of the door latch, so that the through hole of the baffle is matched with the door latch. However, the doorframe may be deformed slightly due to change of humidity and temperature and the door latch cannot perfectly extend through the through hole of the baffle. The users need to forcibly push or hit the door to ensure that the door latch extends through the through hole of the baffle, and this is disturbing for the users. In order to improve the situation, a new doorframe may be needed, or the baffle and the recess in the doorframe need to be re-positioned. Sometimes this could involve high cost or complicated work. Besides, if the users want to remove the old baffle and install a new baffle, a precise installation is expected and some users may not be able to achieve the expected installation.
The present invention intends to provide an adjustable baffle and a doorframe having the adjustable baffle, to eliminate the shortcomings mentioned above.
The present invention relates to an adjustable baffle and comprises a base having a room formed in the rear side thereof. A first through hole is defined through the base and located corresponding to the room. A baffle is located in the room and has a second through hole located corresponding to the first through hole of the base. The baffle is movable in at least one movement direction within the room of the base. An elastic element is located between the base and at least one side of the baffle along the at least one movement direction.
Preferably, the first and second through holes accommodates a door latch. The at least one movement direction of the baffle is perpendicular to the movement direction of the door latch. The length of the second through hole of the baffle along the at least one movement direction is smaller than the length of the first through hole along the at least one movement direction.
Preferably, the elastic element is a curve plate.
Preferably, there are two elastic elements which are located to two opposite sides of the baffle along the at least one movement direction and the base 1 respectively.
Preferably, the baffle includes a guide face formed on one face thereof and located along the periphery of the second through hole.
Preferably, the guide face is an inclined face or a curve face.
Preferably, the base includes a notch defined in one end thereof. A cover is attached to the rear side of the base and engaged with the notch. The cover includes a third through hole which is located corresponding to the first through hole.
Preferably, the base includes at least one first bore. The cover includes a second bore located corresponding to the at least one first bore. At least one connector is connected to the at least one first bore and the second bore.
Preferably, the at least one first bore and the second bore both are a hole. The at least one connector is a positioning part.

The present invention provides a doorframe that includes a recess. An adjustable baffle is located in the recess. The adjustable baffle comprises a base and a baffle. The base has a room formed in the rear side thereof. A first through hole is defined through the base. The first through hole is larger than the recess. The baffle is located in the room and has a second through hole which is located corresponding to the first through hole of the base. The second through hole is smaller than the first through hole. The baffle is movable in at least one movement direction within the room of the base. An elastic element is located between the base and at least one side of the baffle along the at least one movement direction.
The advantages of the present invention are that the baffle is movable in the movement direction within the room of the base so that when installing the door lock and they baffle, the tolerance between the lock latch and the recess of the doorframe, and the tolerance between the lock latch and the second through holes of the baffle can be corrected and adjusted by the baffle being moved by compressing the elastic element. The lock latch is then guided by the guidance of the guide face of the baffle to precisely and properly extend through the second through holes so that the lock latch is able to be inserted into the recess in the doorframe smoothly. In addition, by the elastic element, the baffle and the lock latch do not hit and interfere with each other when the lock latch is inserted into or removed from the recess of the doorframe.
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.
Referring to
A baffle 2 is located in the room 11 and can be movable in at least one movement direction within the room 11 of the base 1. An elastic element 3 is located between the base 1 and at least one side of the baffle 2 along the at least one movement direction. In this embodiment, there are two elastic elements 3 but not limited thereto. The two elastic elements 3 are located to two opposite sides of the baffle 2 along the at least one movement direction and the base 1 respectively. A second through hole 21 is defined through the baffle 2 and located corresponding to the first through hole 13 of the base 1. The length of the second through hole 21 of the baffle 2 along the at least one movement direction is smaller than the length of the first through hole 13 along the at least one movement direction.
The base 1 is installed to a recess 41 of a doorframe 4. A door (not shown) is pivotably connected to the doorframe 4 and includes a door lock (as shown in
In this embodiment, the baffle 2 includes a guide face 22 formed on one face thereof and located along the periphery of the second through hole 21. The guide face 22 is an inclined face, the inner periphery of the second through hole 21 gradually widens from one of the two ends of the baffle 2 that is remote to the door toward another one of the two ends of the baffle 2 that is close to the door. By the guide face 22, when the lock latch 5 is offset relative to the second through hole 21 of the baffle 2, as shown in
The size of the first through hole 13 is larger than the second through hole 21, and larger than the cross section of the lock latch 5 as shown in
This feature allows the lock latch 5 to be inserted into the recess 41 of the doorframe 4 as expected when a poor or un-experienced installation happens, as long as the lock latch 5 is located in the first through hole 13. When the adjustable baffle is used for electronic lock, the lock latch 5 is driven by a motor, the movable baffle provides solutions to poor installation or mis-alignment between the lock latch 5 and the recess 41 of the doorframe 4. As long as the lock latch 5 extends through the first through hole 13, the doorframe 4 does not need to be adjusted or re-installed, and the door with the door lock do not need to be re-installed.
As shown in
On the contrary, when the lock latch 5 is removed from the second through hole 21, by the guidance of the guide face 22 and the operation of the elastic elements 3, the lock latch 5 is easily removed from the base 1 and the baffle 2. Therefore, door latch 5 is smoothly and easily operated between lock and unlock actions.
In this embodiment, each elastic element 3 is a single spring strip, and two ends of each elastic element 3 contacts against the base 1, and the middle portion of each elastic element 3 contacts the baffle 2 and which provides a recovery force to the baffle 2 and avoids the baffle 2 from being inclined during movements of recovery and shifting.
As described above, the elastic elements 3 are used to avoid the baffle 2 from being inclined during movements of recovery and shifting. Preferably, the elastic elements 3 are curved strips. The directions that the force applied to the baffle 2 are left and right, so that the movement direction of the baffle 2 is left and right when facing the front side of the baffle 2. In one embodiment, the elastic elements 3 are located to two opposite sides of the baffle 2 along the movement direction and the base 1 respectively. In one embodiment, only one elastic element 3 located between one side of the baffle 2 and the base 1. Alternatively, one elastic element 3 is located between each of the top end and the bottom end of the baffle 2.
A cover 14 is attached to the rear side of the base 1 and engaged with the notches 12 so as to position the baffle 2. The cover 14 includes a third through hole 141 which is located corresponding to the first through hole 13. The base 1 includes at least one first bore 15. The cover 14 includes at least one second bore 142 located corresponding to the at least one first bore 15. In this embodiment, the base 1 includes two first bores 15, and the cover 14 includes two second bores 142. The at least one first bore 15 and the at least one second bore 142 both are a hole, and the at least one connector 16 is a positioning part. In one embodiment, the at least one connector 16 can be a ring-shaped connector and includes a passage 161 defined centrally therethrough so that a bolt (not shown) extends through the passage 161 and is connected to the doorframe 4. The head of the bolt contacts against the at least one connector 16 to fix the adjustable baffle to the doorframe 4.
In order to prevent the connectors 16 from being interfered to the baffle 2, the baffle 2 includes two slots 23 which are located corresponding to the connectors 16 and extend in the movement direction mentioned above. The slots 23 extend along the at least one movement direction, the connectors 16 extend respectively through the slots 23. When the baffle 2 is moved, the connectors 16 move within the slots 23.
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.
