Description

Door frame mounting mechanism for digital door locks {Apparatus that fixed on door frame for digital doorlock}

The present invention relates to a door frame mounting mechanism, and more particularly to a door frame mounting mechanism for a digital door lock is equipped with a magnet to enable the digital door lock to determine whether the door is open.

The general door lock includes a latch bolt that protrudes and retracts toward the side of the door by operating a rotation means such as a lever. The latch bolt is a means for preventing the door from opening automatically, not a means for locking and releasing. In order to solve the instability of the latch bolt only, a mortise lock having a locking structure by the latch bolt and the dead bolt is installed and used by installing a dead bolt that is locked and released by a knob or grip. .

In addition, a digital door lock has been developed and used to release dead bolts by pressing a key input button on the outside of the door or using a safety key with a semiconductor chip, and pressing a button inside the door by the power of a motor. Such a digital door lock is convenient because even if the user forgets to lock the door, the dead bolt can be automatically moved to the locked position by the power of the motor after the door is closed.

This automatic locking function is achieved in several ways. Representative among them is the mechanical method of confirming the closing by pressing the sub latch, and the electric-electronic sensing that recognizes the magnetic field of the magnet by Hall IC or Reed S / W. There is a way.

Among them, the digital door lock equipped with the magnet and the Hall IC (or Reed S / W) method recognizes the magnetic field of the magnet located in the door frame, determines whether the door is open, and then transfers the dead bolt. The dead bolt of the digital door lock can be drawn in, and the mechanism provided with the magnet is called a door frame mounting mechanism.

1 is a view for explaining a conventional door frame mounting mechanism 100. Referring to Figure 1, the conventional door frame mounting mechanism 100 is composed of a door frame body 110, a magnet 130 and a cover 140.

The door frame main body 110 is opened downward (part facing the body front of the door lock) so that the dead bolt of the door lock can be retracted, and the magnet seating part recessed to a predetermined depth in the upper side of the door frame main body 110. 120 is formed. When the magnet 130 is inserted into the magnet seating part 120 of the door frame body 110 and the cover 140 is covered, the cover 140 is caught on the latching jaw 121 formed in the magnet seating part 120. 140 and the magnet 130 is fixed together. When the door frame mounting mechanism 100 assembled as described above is fixed to the door frame, the dead bolt of the door lock is inserted into the inner space of the door frame body 110, thereby enabling locking and opening.

At this time, if the digital door lock is closed, the Hall IC or Reed S / W located inside the body front from which the dead bolt protrudes from the digital door lock recognizes the magnetic field to determine whether the door is open or closed. do. In other words, if the door is open, the magnetic field does not interfere with the Hall IC or the Reed S / W, and no operation occurs. On the other hand, if the door is closed, the magnetic field of the magnet 130 provided in the door frame mounting mechanism 100 is recognized by the Hall IC or Reed S / W to drive the motor to protrude the dead bolt. That is, the lock is made automatically.

Here, in the conventional door frame mounting mechanism 100, by inserting a wide plate-shaped magnet 130 in the form of lying down from above the door frame body 110, a constant distance (D) between the magnet 130 and the body front of the door lock. Put it. This is to secure a space that the latch bolt of the door lock can be retracted. However, since the distance (D) between the Hall IC or the Reed S / W located inside the body front of the door lock and the magnet 130 is far, the sensitivity of the Hall IC or the Reed S / W to detect the magnet 130 is deteriorated. none. Therefore, in order to detect the magnetic field of the magnet 130 in the Hall IC or Reed S / W, a large size magnet 130 must be used, which increases the manufacturing cost and the door frame body 110 due to the large size of the magnet 130. There is a problem that it is difficult to utilize the space in the).

In addition, the door frame has to dig a hole as much as the depth of the door frame body 110 is inserted, but if the door frame itself is not possible to secure the depth there is a problem that the door frame mounting mechanism 100 can not be installed.

The present invention was devised to solve the problems of the prior art as described above, and when the door is closed, the magnet can be detected at the position as close as possible to the Hall IC or Reed S / W of the door lock, so that the accuracy of detecting the door closing is improved. The object is to provide a door frame mounting mechanism for an improved digital door lock.

In addition, there is another object to provide a door frame mounting mechanism that can be mounted on the door frame without deterioration even if the depth of the door frame is low.

The door frame mounting mechanism for a digital door lock according to the present invention for achieving the above object, is mounted to the door frame, has a bolt inlet space into which the dead bolt of the door lock is inserted, the dead bolt in the bolt inlet space A magnet fixing frame is provided in which a magnet is erected and fixed in a space except a position into which the magnet is inserted, and the magnet fixing frame extends from the door lock to a position where the dead bolt protrudes.

On the other hand the door frame mounting mechanism for a digital door lock according to the present invention for achieving the above object, the first door case case body is mounted to the door frame and has a bolt inlet space into which the dead bolt of the door lock is inserted; A magnet fixing frame provided in a space other than the position where the dead bolt is drawn in the bolt inlet space of the first door case body and the magnet fixing frame to which the magnet is erected and fixed to the support frame supporting the magnet door to the first door case body. First door case made of; A second door case coupled to the first door case on an opposite side of the surface of the first door case in contact with the body front of the door lock; And a rod-shaped magnet seated and fixed to the magnet fixing frame of the first door case, wherein the magnet fixing frame of the first door case extends to a position in contact with the body front from which the dead bolt protrudes from the door lock. It is.

Here, one side of the magnet fixing frame of the first door case is open, the rod-shaped magnet is fitted and seated on the open one side, the magnet preventing the detachment of the seated magnet around the open one side A fixed hook can be formed.

In addition, a coupling hook is formed by extending from one side of the second door case, and the coupling hook of the second door case may be fixed by being locked to the fixing frame supporting part of the first door case.

The dead bolt and the latch bolt of the door lock may be inserted into the bolt insertion space of the first door case, and the magnet fixing frame may be spaced between the dead bolt and the latch bolt of the door lock from the bolt insertion space. It can be located at

According to the present invention, the following effects are obtained.

First, since the small sized bar magnet is installed as close as possible to the body front of the digital door lock, the sensitivity of magnetic detection of the magnet by the Hall IC or Reed S / W located inside the body front of the door lock is greatly improved. . Therefore, even if the magnet is small size, there is no risk of malfunction due to the close distance to the Hall IC or Reed S / W. In addition, the magnet fixing frame, which uses a small size of magnet, and the bar magnet is seated, does not invade the space where the dead bolt or latch bolt of the door lock enters, but the space between the space where the dead bolt and the latch bolt enters. ) Is effective in terms of space utilization.

Second, since the door frame mounting mechanism is composed of two stages of the first door case and the second door case, it is possible to install the door frame having a relatively thin thickness. That is, when the thickness of the door frame is thin, a tool such as a screwdriver is inserted into the separation groove formed in the second door case to separate the first door case and the second door case, and then the first door in the state where the magnet is mounted. By inserting only the frame case into the door frame, the door frame mounting mechanism can be installed without changing the magnet detection performance of Hall IC or Reed S / W.

Third, when installing the door frame mounting mechanism to the door frame can be reversed upside down to prevent the mistake of assembly. That is, the misassembly prevention jaw is provided in the space where the latch bolt is inserted in the first door case, so that the user who has confirmed the misassembly prevention jaw can correctly mount the door frame with the misassembly prevention jaw in the downward direction. have.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings, but some components irrelevant to the gist of the present invention will be omitted or compressed, but the omitted configuration is not necessarily a configuration that is not necessary in the present invention. It can be used in combination by those of ordinary skill in the art.

Figure 2 is an exploded perspective view for explaining the door frame mounting mechanism 1 (hereinafter referred to as 'door frame mounting mechanism 1') for the digital door lock according to an embodiment of the present invention, Figure 3 is a door frame mounting mechanism (1) is a perspective view of the engagement, and FIG. 4 is a sectional view of the door frame mounting mechanism (1). Hereinafter, 'digital door lock' and 'door lock' may be used interchangeably, but both mean 'digital door lock 40'.

2 to 4, the door frame mounting mechanism 1 according to the embodiment of the present invention includes a first door case 10, a magnet 30 and a second door case 20. .

The first door case 10 is largely composed of a first door case body 11 and a magnet fixing frame 12. The first door case body 11 is provided with a bolt inlet space 17 through which the dead bolt 43 and the latch bolt 48 of the door lock 40 enter. In addition, the upper and lower parts of the first door case body 11 are open, and when the body front 42 of the door lock 40 is positioned at the bottom in FIG. 2, the dead bolt 43 may be introduced to the left side and the right side to the right side. The latch bolt 48 may be retracted.

The magnet fixing frame 12 is positioned in the inner bolt retracting space 17 of the first door case body 11. More specifically, in FIG. 2, the magnet fixing frame 12 is positioned between the dead bolt 43 and the latch bolt 48 of the door lock 40 in the bolt inlet space 17. This is because the magnet fixing frame 12 does not interfere with the introduction of the dead bolt 43 and the latch bolt 48.

The magnet fixing frame 12 has a substantially cylindrical shape, the bottom is blocked and the top is open. Therefore, when the rod-shaped or cylindrical magnet 30 is inserted in the upright position of the magnet fixing frame 12, it is inserted into the magnet seating portion 13 inside the magnet fixing frame 12 and seated thereon. At this time, the magnet fixing hook 14 is formed on the open upper circumference of the magnet fixing frame 12 so that after the magnet 30 is inserted into the magnet fixing frame 12, it is caught on the jaw of the magnet fixing hook 14 to be separated. Is prevented.

The magnet fixing frame 12 is supported by the first frame case body 11 by a fixing frame supporting part 15 extending laterally around the magnet fixing frame 12.

The second bottle case 20 includes a coupling hook 22 formed to protrude downward from the second door case body 21 and the second door case body 21. That is, when the magnet 30 is inserted into the fixing frame supporting part 15 of the first door case 10 and the second door case body 21 is fitted above the first door case body 11, The coupling hook 22 below the two-door case main body 21 is fixed to the lower ends of both sides of the fixing frame support 15 of the first door-case case 10.

Here, the door frame mounting mechanism when the second door case 20 is coupled to the first door case 10 and the first door case 10 and the second door case 20 are coupled to each other. When installing (1) to the door frame, it may be necessary to consider the vertical direction. That is, as shown in the cross-sectional view of Figure 4, the magnet fixing frame 12 is not located in the center of the center of the bolt inlet space 17 of the first door case body (11). Of course, the magnet fixing frame 12 may be located in the center of the bolt inlet space 17, but the state of the dead bolt 43 and the latch bolt 48 of the door lock 40 in consideration of the position and size of either side. It can be located as. Ultimately, the magnet fixing frame 12 depends on where the Hall IC 45 (or Reed S / W) is installed in the digital door lock 40 paired with the door frame mounting mechanism 1. You lose. If, for whatever reason, the magnet fixing frame 12 is biased to one side in the bolt inlet space 17 of the first door case body 11, the position of the fixing frame supporting part 15 supporting the magnet fixing frame 12 is also Being biased, the coupling hook 22 of the second door case 20, which is coupled to the fixing frame support 15, should also be biased. Therefore, when the first door case 10 and the second door case 20 are combined, the direction should be considered. If the wrong coupling is attempted because the coupling hook 22 of the second door case 20 may be caught and broken on the upper surface of the fixing frame support (15). In addition, if the door frame mounting mechanism 1 in a state where the first door case 10 and the second door case 20 are coupled to the door frame is inserted with the up and down direction reversed, the first door case In the bolt inlet space 17 of the main body 11, the dead bolt 43 may not be able to enter the correct space and may be caught by the magnet fixing frame 12 to prevent entry.

However, it is not easy for the worker to determine the coupling direction and the direction of inserting the door frame only by looking at the shapes of the first door case 10 and the second door case 20. To this end, a misassembly prevention jaw 16 for preventing misassembly is provided at the end of one of the bolt inlet spaces 17 inside the first door case body 11, and the upper and lower parts of the misassembly prevention jaw 16 are provided. On one side of the face is marked to indicate that it is the bottom (upper implementation). In addition, the surface where the coupling hook 22 protrudes from the second casecase 20 is marked to distinguish the vertical direction.

Therefore, the operator can assemble correctly without confusing the assembling direction by referring to the direction indications marked on the misalignment prevention jaw 16 and the second bottlecase 20 of the first doorcase case 10.

In addition, even when the door frame mounting mechanism 1 in a state where the first door case 10 and the second door case 20 are coupled to the door frame is installed, the first door case 10 By referring to the direction indicated on the misassembly prevention jaw 16, it can be installed correctly so that up and down may not be reversed.

Here, the erroneous assembly prevention jaw 16 is preferably located in the space where the latch bolt 48 is drawn out of the bolt insertion space 17 of the first door case body 11. This is due to the size difference between the dead bolt 43 and the latch bolt 48 of the door lock 40. That is, since the dead bolt 43 serves to firmly support the door so that it is not opened, it is relatively large in size compared to the latch bolt 48, and the locking effect is large when the door bolt mounting mechanism 1 is as deep as possible. However, since the latch bolt 48 is provided to expect only the performance of 'closed' rather than the effect of 'locking', the length and size need not be considered.

Therefore, when the erroneous assembly prevention jaw 16 is positioned at the end of the space in which the latch bolt 48 is drawn out of the bolt insertion space 17 of the first door case body 11, the dead bolt 43 is inserted as deeply as possible. Is not disturbed, the latch bolt 48 is enough to be able to perform its role even if only inserted up to just below the misassembly prevention jaw (16).

On the other hand, as can be seen in the cross-sectional view of Fig. 4, the magnet fixing frame 12 of the first door case 10 extends as far down the first door case body 11 as possible. This is to increase the performance that the magnetic field of the magnet 30 is transmitted to the Hall IC 45 (or Reed S / W) of the door lock 40.

That is, the door is closed and the body front 42 of the door lock 40 is in contact with the door frame mounting mechanism 1, and the dead bolt 43 and the latch bolt 48 are bolted into the first door case 10. Referring to FIG. 5 in a state of protruding into the space 17, the magnet fixing frame 12 is almost in close contact with the body front 42 of the door lock 40, and the magnet 30 is attached to the magnet fixing frame 12. ) Is completely inserted so that the magnet 30 can interfere with the maximum magnetic field to the Hall IC 45 (or Reed S / W) of the door lock 40. Therefore, even if the size of the magnet 30 is not large, the Hall IC 45 (or Reed S / W) recognizes that the door is closed by detecting a strong magnetic field of the magnet 30 while the door is closed. By driving a motor (not shown), the dead bolt 43 may be pushed out to perform automatic locking.

Referring to Figure 5 to look at the operation of the door lock 40 in more detail. Prior to the description, the door lock 40 in FIG. 5 shows only the configuration related to the action of the door frame mounting mechanism 1, and the digital door lock 40 is not necessarily manufactured in the form shown in FIG. 5.

First, when the user inserts the dead bolt 43 into the door lock 40 by the operation of a button or knob, and turns the handle to the latch bolt 48, the dead bolt 43 and the latch bolt 48 are equipped with the door frame. The door can be opened because it is not affected by the mechanism 1 at all. Thereafter, when the door is closed, the latch bolt 48 is protruded from the body front 42 by the force of the spring (not shown) and protrudes into the bolt inlet space 17 of the first door case 10. At this time, Hall IC 45 (or Reed S / W) recognizes the magnetic field generated by magnet 30 across the bodyfront 42 and determines that the door is closed to drive a motor (not shown) to drive a dead bolt (not shown). 43) Push out. In other words, it performs the auto lock function.

If the magnet fixing frame 12 does not extend to the portion where the first front case 10 and the body front 42 of the door lock 40 come into contact with each other, the magnet 30 and the Hall IC 45 (or Reed S / If the distance of W is greater, the strength of the magnetic field transmitted to the Hall IC 45 (or Reed S / W) is also weakened, so that the Hall IC 45 (or Reed S / W) correctly detects the magnet 30. Failure to do so may result in malfunctions. To this end, in the conventional door frame mounting mechanism 100, the magnet 130 having a large size was used, and thus manufacturing cost increased and space utilization in the door frame mounting mechanism 100 was not efficient.

In FIG. 5, reference numerals 41, 43a, 44, 46, and 47 denote the lower case 41 of the door lock 40, the protrusion 43a of the dead bolt 43, the PCB 44, and the photosensors 46, respectively. , 47). The photosensors 46 and 47 are used to determine whether the dead bolt 43 is in an open state or a closed state by recognizing the position of the protrusion 43a of the dead bolt 43, and the PCB 44 is a Hall IC. 45 (or Reed S / W) and to control the functional operation of the door lock 40 through the signal detected from the photosensors.

On the other hand, since the door frame mounting mechanism 1 according to the embodiment of the present invention is composed of two stages so that the first door case 10 and the second door case 20 can be combined and separated, It can be deformed and installed depending on the thickness.

That is, the door frame mounting mechanism 1 is basically inserted into the hole provided in the door frame while the second door case 20 is coupled to the first door case 10. However, since the thickness of the door frame itself is thin, it may not be possible to secure a space into which the entire door frame mounting mechanism 1 is inserted.

In this case, only the first door case 10 in which the magnet 30 is mounted may be inserted into the door frame. To this end, one or more separation grooves 23 are provided on the outside of the second door case 20 so that an operator can easily separate the first door case 10 and the second door case 20 in a coupled state. ) Is formed.

That is, as shown in FIG. 3, in the state in which the first door case 10 and the second door case 20 are coupled, the coupling hook 22 of the second door case 20 is formed in the first door case ( It is difficult to separate by hand because it is firmly coupled to the fixing frame support (15) of 10). At this time, if a worker inserts a tool such as a screwdriver into the separation groove 23 formed on the outer side where the first door case 10 and the second door case 20 are in contact with each other, the first door is driven by the force of the tool. The frame case 10 and the second door case 20 can be easily separated.

Therefore, in the state where the second door case 20 is separated, only the first door case 10 having the magnet 30 mounted therein can be completely inserted into the thin door frame. Even in this case, the magnet 30 may maintain a state as close as possible to the body front 42 of the door lock 40. Therefore, the performance of detecting the magnetic field of the magnet 30 by the Hall IC 45 (or Reed S / W) of the door lock 40 is not deteriorated.

As described in detail above, according to the present invention, the Hall IC or Reed S / W located in the body front of the door lock is installed as close to the body front of the digital door lock as the small bar magnet is built up. Sensitivity to detect is greatly improved. Therefore, even if the magnet is small size, there is no risk of malfunction due to the close distance to the Hall IC or Reed S / W. In addition, the magnet fixing frame, which uses a small size of magnet, and the bar magnet is seated, does not invade the space where the dead bolt or latch bolt of the door lock enters, but the space between the space where the dead bolt and the latch bolt enters. ) Is effective in terms of space utilization.

In addition, since the door frame mounting mechanism is composed of two stages of the first door case and the second door case, it is possible to install the door frame having a relatively thin thickness. That is, when the thickness of the door frame is thin, a tool such as a screwdriver is inserted into the separation groove formed in the second door case to separate the first door case and the second door case, and then the first door in the state where the magnet is mounted. By inserting only the frame case into the door frame, the door frame mounting mechanism can be installed without changing the magnet detection performance of Hall IC or Reed S / W.

In addition, when installing the door frame mounting mechanism to the door frame, it is possible to prevent the mistake of assembling upside down direction. That is, the misassembly prevention jaw is provided in the space where the latch bolt is inserted in the first door case, so that the user who has confirmed the misassembly prevention jaw can correctly mount the door frame with the misassembly prevention jaw in the downward direction. have.

Preferred embodiments of the present invention described above are for the purpose of illustration, and those skilled in the art having ordinary knowledge of the present invention will be capable of various modifications, changes and additions within the spirit and scope of the present invention, such modifications, changes And addition should be seen as belonging to the utility model registration claim of the present invention.
