Technical Field

[0001] This invention relates to the fields of high-end equipment manufacturing and biomedical industry technology, and in particular to a lock and a medical cabinet. Background Technology

[0002] Medical cabinets are used to store medicines, consumables, and other items. They are typically equipped with locks to prevent unauthorized personnel from opening them. However, some existing locks are not very secure, which hinders the overall security of medical cabinets. For example, during forced opening, the latch, which should be fixed, can easily move, increasing the risk of the lock being unlocked by unauthorized means, thus compromising security. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a lock that provides high security.

[0004] The present invention also provides a medical cabinet including the above-mentioned lock.

[0005] According to an embodiment of the first aspect of the present invention, a lock includes: a lock ring; a lock housing, separately disposed from the lock ring; a bolt, movably connected to the lock housing, the bolt being capable of connecting to the lock ring and preventing the lock ring from moving away from the lock housing; a connecting member, movably connected to the lock housing, abutting the bolt at a first end to prevent the bolt from disengaging from the lock ring, and abutting the lock housing at a second end to prevent the bolt from pushing the connecting member; and a driving mechanism, installed inside the lock housing, capable of driving the connecting member to move to release the abutment between the first end and the bolt.

[0006] According to a first aspect of the present invention, the lock has at least the following beneficial effects: when the lock is in the locked state, if the user forcibly pulls the lock ring away from the lock housing, the bolt connected to the lock ring will tend to move; furthermore, since the bolt abuts against the first end of the connecting member, the connecting member also tends to be pushed and moved by the bolt. Since the second end of the connecting member abuts against the lock housing, the abutment between the lock housing and the second end can prevent the connecting member from being pushed by the bolt, thereby ensuring the positional stability of the bolt in the locked state and improving the security of the lock.

[0007] According to some embodiments of the present invention, the lock further includes a positioning member installed inside the lock housing, and the bolt has a first positioning groove. When the first end abuts against the bolt, the positioning member is engaged in the first positioning groove.

[0009] According to some embodiments of the present invention, the lock has a clearance hole, the second end passes through the clearance hole, and a portion of the second end is located outside the lock housing. The second end abuts against the wall of the clearance hole to prevent the bolt from pushing the connector.

[0010] According to some embodiments of the present invention, the driving mechanism includes a main body, a movable rod, and a retaining block. The main body is fixed to the lock housing, the movable rod is movably connected to the main body, and the retaining block is fixed to the end of the movable rod. The retaining block abuts against the third end of the connecting member and can prevent the bolt from pushing the connecting member. The movable rod can move relative to the main body and cause the retaining block to push the connecting member to move in a first direction to release the abutment between the first end and the bolt. The driving mechanism also includes an elastic member, the two ends of which are respectively connected to the lock housing and the connecting member. The elastic force of the elastic member can drive the connecting member to move in a second direction and reset. The second direction is opposite to the first direction.

[0011] According to some embodiments of the present invention, the lock housing includes a pivot portion, and the connecting member includes a first abutting portion, a second abutting portion, a third abutting portion, and a connecting portion. The connecting portion has a rotating hole, and the pivot portion passes through the rotating hole. The first abutting portion, the second abutting portion, and the third abutting portion are radially connected to the connecting portion. The first end is disposed at the end of the first abutting portion away from the rotating hole, the second end is disposed at the end of the second abutting portion away from the rotating hole, and the third end is disposed at the end of the third abutting portion away from the rotating hole.

[0012] According to some embodiments of the present invention, the lock further includes a first detector, which is installed inside the lock housing and spaced apart at one end of the main body; the abutment block can move to a position that can trigger the first detector to push the connector to move thereby releasing the abutment between the first end and the bolt.

[0013] According to some embodiments of the present invention, the lock further includes a second detector, which is installed inside the lock housing and is communicatively connected to the drive mechanism; when the second detector is triggered by the bolt, the drive mechanism drives the connector to reset so that the first end abuts against the bolt.

[0014] According to some embodiments of the present invention, the lock further includes a third detector installed inside the lock housing, and the connector further includes a trigger portion connected to the side of the second end; when the first end abuts against the bolt, the trigger portion triggers the third detector.

[0015] According to an embodiment of the second aspect of the present invention, a medical cabinet includes: a cabinet body having an internal receiving cavity; a cabinet door movably connected to the cabinet body and covering the receiving cavity; a lock as described in the first aspect embodiment, wherein one of the lock ring and the lock housing is connected to the cabinet door and the other is connected to the cabinet body; a lock cylinder installed on the cabinet door or the cabinet body, the lock cylinder being for key insertion; and a linkage member having two ends connected to the lock cylinder and the connecting member respectively, the lock cylinder being rotatable and driving the linkage member to move, so that the linkage member drives the connecting member to move thereby releasing the abutment between the first end and the lock tongue.

[0016] According to the second aspect of the present invention, the medical cabinet has at least the following advantages: due to the high security of the lock, the medical cabinet is also highly secure, and the items inside the medical cabinet are not easily lost or stolen.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] Reference Figure 1 This invention provides a lock 100, which includes a lock ring 102, a lock housing 101, a lock tongue 104, a drive member 106, and a connecting member 105. The lock ring 102 and lock housing 101 can be installed on two different objects, for example, the lock ring 102 can be installed on a door, and the lock housing 101 can be installed on a door frame; or, as described below, in the medical cabinet 400 (e.g.) Figure 7 As shown, the locking ring 102 is installed on the cabinet door 402, and the lock housing 101 is installed on the cabinet body 401. That is, two objects that need to be locked by the lock 100 can be connected to the locking ring 102 and the lock housing 101 respectively, which will not be listed here.

[0038] The bolt 104, drive member 106, and connecting member 105 are all connected to the lock housing 101, wherein the connecting member 105 and the bolt 104 are movably connected to the lock housing 101. (Refer to...) Figure 1 and Figure 2 The lock housing 101 and the lock ring 102 are separate components, and can be separated from each other. (Refer to...) Figure 4 When the bolt 104 is connected to the locking ring 102, and the bolt 104 is held abutted by the connecting member 105, the lock 100 is in a locked state; in contrast Figure 4 and Figure 6 When the lock 100 is in the locked state, the bolt 104 can prevent the lock ring 102 from moving away from the lock housing 101. At this time, the two objects connected to the bolt 104 and the lock housing 101 respectively are locked. (Refer to...) Figure 6 When the bolt 104 disengages from the lock ring 102, the lock 100 is in the unlocked state, at which time the two objects connected to the bolt 104 and the lock housing 101 can move relative to each other.

[0039] Reference Figure 4When the lock 100 is in the locked state: the first end of the connector 105 abuts against the bolt 104 to prevent the bolt 104 from moving and disengaging from the lock ring 102 (preventing the bolt 104 from rotating clockwise); and the second end of the lock housing 101 abuts against and prevents the bolt 104 from driving the connector 105 to move (preventing the bolt 104 from pushing the connector 105 to rotate counterclockwise). Figures 4 to 6 The driving component 106 can drive the connecting component 105 to move, releasing the resistance between the first end and the bolt 104, thereby allowing the bolt 104 to disengage from the locking ring 102, and thus allowing the lock 100 to switch from the locked state to the unlocked state.

[0040] For example, refer to Figure 2 and Figure 3 The connector 105 includes a first abutting portion 201 and a second abutting portion 202. A first end is disposed on the first abutting portion 201, and a second end is disposed on the second abutting portion 202. The first end can be the end of the first abutting portion 201 away from the rotation center of the connector 105, and the second end can be the end of the second abutting portion 202 away from the rotation center of the connector 105. The first abutting portion 201 abuts against the latch 104, thereby abutting the first end against the latch 104; the second abutting portion 202 abuts against the lock housing 101, thereby abutting the second end against the lock housing 101.

[0041] The following example, using the connection between the lock housing 101 and the door frame and the lock ring 102 and the door as an example, and referring to the specific directions in the attached drawings, briefly explains why this lock 100 has high security. (Refer to...) Figure 4 When the lock 100 is locked, if the user needs to forcibly pull the door out of the door frame, the lock ring 102 will tend to move to the left, and correspondingly, the bolt 104 connected to the lock ring 102 will tend to move clockwise. Furthermore, since the bolt 104 abuts against the first abutment portion 201 (first end), the connecting member 105 tends to be pushed by the bolt 104 and rotate counterclockwise. (Refer to...) Figure 4 Since the second abutting part 202 (second end) of the connector 105 abuts against the lock housing 101, the lock housing 101 prevents the connector 105 from rotating counterclockwise, thereby preventing the movement of the bolt 104, ensuring the positional stability of the bolt 104 in the locked state, thereby improving the security of the lock 100.

[0042] The specific structure of lock 100 will be explained below.

[0043] In one embodiment, reference is made to Figure 1The lock housing 101 has a relief groove 103 on its outer surface. The lock ring 102 can move in and out of the relief groove 103. The relief groove 103 communicates with the cavity inside the lock housing 101. The lock tongue 104 includes a first protrusion 213 and a second protrusion 214 spaced apart. The movable connection between the lock tongue 104 and the lock housing 101 is specifically a rotatable connection. The movable connection between the connecting member 105 and the lock housing 101 is also specifically a rotatable connection. For example, as... Figures 4 to 6 As shown, during the process of the lock 100 switching from the locked state to the unlocked state, the connecting member 105 rotates clockwise; during the process of the lock 100 switching from the unlocked state to the locked state, the connecting member 105 rotates counterclockwise.

[0044] Combination Figure 1 and Figure 4 The first protrusion 213 can move into the clearance groove 103 and pass through the locking ring 102 located in the clearance groove 103. In the locked state, since the position of the bolt 104 is fixed, the first protrusion 213 passing through the locking ring 102 can prevent the locking ring 102 from leaving the clearance groove 103, thereby preventing the locking ring 102 from moving away from the lock housing 101. (Refer to...) Figure 5 When the first abutment 201 no longer abuts the latch 104, although the latch 104 still passes through the lock ring 102, the latch 104 can move. The user can drive the lock ring 102 to move away from the lock housing 101 (for example, to move the lock ring 102 to the left). When the lock ring 102 moves, it can push open the latch 104 (the latch 104 rotates clockwise) and eventually separate from the first protrusion 213 of the latch 104. Then refer to the following... Figure 6 and Figure 5 During the process of pushing the locking ring 102 into the relief groove 103, the locking ring 102 can abut against the second protrusion 214 and push the locking tongue 104 to rotate (counterclockwise); as the locking tongue 104 rotates, the first protrusion 213 gradually inserts into the locking ring 102.

[0045] Reference Figure 2 In one embodiment, the driving mechanism includes a driving member 106 and an elastic member 204. The driving member 106 includes a main body 206, a movable rod 205, and a supporting block 207. The movable rod 205 is movably connected to the main body 206, and the supporting block 207 is connected to the end of the movable rod 205, abutting against the connecting member 105. Figures 4 to 6The movable lever 205 can move relative to the main body 206, thereby causing the abutment block 207 to push the connecting member 105 to move in the first direction. Moreover, the abutment action between the abutment block 207 and the connecting member 105 can prevent the connecting member 105 from being pushed by the latch 104. The two ends of the elastic member 204 are connected to the lock housing 101 and the connecting member 105 respectively. The elastic force of the elastic member 204 is used to drive the connecting member 105 to move and reset in the second direction, thereby causing the first abutment portion 201 to abut against the latch 104. The first direction is opposite to the second direction.

[0046] Specifically, in combination Figure 4 and Figure 5 As the distance between the abutment block 207 and the main body 206 gradually increases, the abutment block 207 gradually pushes the connector 105 to rotate clockwise (i.e., the connector 105 moves clockwise along the first direction), thereby releasing the abutment between the first end (first abutment part 201) and the locking tongue 104. During this process, the elastic member 204 is gradually compressed. When the distance between the abutment block 207 and the main body 206 gradually decreases, the elastic member 204 gradually returns to its original length, and the elastic force of the elastic member 204 drives the connector 105 to rotate counterclockwise (i.e., the connector 105 moves counterclockwise along the second direction).

[0047] Reference Figure 4 In the locked state, the abutment block 207 abuts against the third end of the connector 105, thereby preventing the connector 105 from rotating counterclockwise. For example, refer to... Figure 3 The connecting member 105 also includes a third abutment portion 201, with a third end disposed on the third abutment portion 201. This third end can be the end of the third abutment portion 201 furthest from the rotation center of the connecting member 105. Therefore, when the lock 100 is in the locked state, the abutment block 207 of the drive mechanism has a limiting effect on the connecting member 105, and the lock housing 101 also has a limiting effect on the connecting member 105. This improves the positional stability of the connecting member 105 in the locked state, thereby improving the positional stability of the bolt 104 and ultimately enhancing the security of the lock 100.

[0048] Specifically, the lock housing 101 includes a pivot portion 501 (such as...). Figure 2 As shown), the connector 105 also includes a connecting portion 502 (as shown). Figure 3 As shown, the connecting part 502 is rotatably sleeved on the outside of the rotating shaft part 501. (See reference...) Figure 3The connecting portion 502 has a rotating hole 503, and the rotating shaft portion 501 passes through the rotating hole 503. The first abutting portion 201, the second abutting portion 202, and the third abutting portion 203 are radially connected to the connecting portion 502. That is, the first abutting portion 201, the second abutting portion 202, and the third abutting portion 203 all protrude radially relative to the connecting portion 502 along the rotating hole 503, and the first abutting portion 201, the second abutting portion 202, and the third abutting portion 203 are distributed circumferentially along the rotating hole 503. Since the first abutment 201, the second abutment 202 and the third abutment 203 are radially connected to the connecting part 502, the connecting member 105 is generally formed with three legs (each abutment part corresponds to one leg), and each leg has a corresponding abutment point (the leg abuts against other parts of the lock 100). The three abutment points make the connecting member 105 generally form a triangular limit on the bolt 104, thereby effectively improving the stability and security of the lock 100 in the locked state.

[0049] Reference Figure 3 In one embodiment, the outer surface of the second abutment 202 further has a relief arc surface 504; combined with Figures 4 to 6 The avoidance arc surface 504 is used to avoid obstructing the bolt 104 so that the second abutment part 202 does not hinder the rotation of the bolt 104 in the unlocked state. When the second abutment part 202 is provided with the avoidance arc surface 504, the distance between the bolt 104 and the connecting member 105 can be set to be smaller (in the unlocked state), which is beneficial to improve the internal space utilization of the lock housing 101, improve the structural compactness of the lock 100, and reduce the volume of the lock 100.

[0050] The driving component 106 can be configured as an electromagnet or an electric actuator. When the driving component 106 is configured as an electromagnet, the main body 206 includes a housing and a coil located inside the housing. The magnetic force generated when the coil is energized is used to drive the movable rod 205 to move. When the driving component 106 is configured as an electric actuator, the main body 206 includes a housing and a motor and transmission components located inside the housing. The motor drives the movable rod 205 to move through the transmission components.

[0051] In one embodiment, reference is made to Figure 4The lock 100 also has a clearance hole 211, with a second end (second abutment portion 202) passing through the clearance hole 211. A portion of the second end (second abutment portion 202) is located inside the lock housing 101, while the other portion protrudes through the clearance hole 211 to the outside of the lock housing 101. In the locked state, the second end (second abutment portion 202) abuts against the lock housing 101, specifically, the side of the second end (second abutment portion 202) abuts against the wall of the clearance hole 211, thereby preventing the connector 105 from rotating counterclockwise. Furthermore, in this configuration, the portion of the second abutment portion 202 exposed outside the lock housing 101 can be connected to an emergency unlocking mechanism (which will be described in detail below), thus enabling the lock 100 to be unlocked by a key; that is, even if unlocking by the drive member 106 is not possible, the lock 100 can still be unlocked.

[0052] Reference Figure 4 In one embodiment, the lock 100 further includes a positioning member 212 connected to the lock housing 101. The bolt 104 has a first positioning groove 301. When the first abutting part 201 abuts against the bolt 104 (or, when the lock 100 is in the locked state), the positioning member 212 is engaged in the first positioning groove 301. The positioning member 212 and the groove wall of the first positioning groove 301 abut against each other, thereby hindering the movement of the bolt 104. The positioning member 212 and the first positioning groove 301 can further improve the positional stability of the bolt 104 in the locked state, thereby improving the security of the lock 100.

[0053] Combination Figures 4 to 6 In one embodiment, the latch 104 further has a second positioning groove 302, and the first positioning groove 301 and the second positioning groove 302 are spaced apart along the movement direction of the latch 104. Figure 6 As shown, when the latch 104 disengages from the locking ring 102, the positioning element 212 engages in the second positioning groove 302. More specifically, the positioning element 212 can be configured as a positioning pin, and correspondingly, the first positioning groove 301 and the second positioning groove 302 can be configured as arc-shaped grooves.

[0054] To further explain the purpose of the second positioning groove 302, the process of the lock tongue 104 disengaging from the lock ring 102 when both the first positioning groove 301 and the second positioning groove 302 are provided on the lock tongue 104 will be described below. Refer to the following... Figure 5 and Figure 6 As the locking ring 102 gradually moves away from the clearance groove 103, the locking ring 102 can abut against the first protrusion 213, and the force applied by the locking ring 102 to the bolt 104 can drive the positioning member 212 to disengage from the first positioning groove 301 and push the bolt 104 to rotate (clockwise); under the push of the locking ring 102, the bolt 104 moves from... Figure 5 Rotate to the position shown. Figure 6 After reaching the indicated position, the positioning member 212 is engaged in the second positioning groove 302, and then the driving member 106 drives the connecting member 105 to move, so that the first abutting part 201 abuts against the locking tongue 104.

[0055] Reference Figure 2 A notch 215 is formed between the first protrusion 213 and the second protrusion 214, for combination Figure 2 and Figure 6 During the process of the locking ring 102 entering the clearance groove 103, in order for the bolt 104 to pass through the locking ring 102, the locking ring 102 needs to enter the notch 215 at a suitable angle. If the positioning member 212 is stuck in the second positioning groove 302 in the unlocked state, the position of the bolt 104 can be fixed, and the orientation and position of the notch 215 are also fixed; this helps to reduce the positional deviation of the bolt 104 in the unlocked state, thereby preventing the locking ring 102 from failing to enter the clearance groove 103 smoothly and preventing the locking ring 102 from failing to connect smoothly with the bolt 104.

[0056] In addition, refer to the following in sequence Figure 6 and Figure 5 When the latch 104 is provided with both a first positioning groove 301 and a second positioning groove 302, as the locking ring 102 gradually enters the clearance groove 103, the locking ring 102 can abut against the second protrusion 214. The force applied by the locking ring 102 to the latch 104 can drive the positioning member 212 to disengage from the second positioning groove 302 and push the latch 104 to rotate (counterclockwise). Under the push of the locking ring 102, the latch 104 moves from... Figure 6 Rotate to the position shown. Figure 5 After reaching the indicated position, the positioning element 212 is engaged in the first positioning groove 301.

[0057] In some embodiments, the lock 100 further includes a detector for detecting the position of certain key components within the lock 100 to determine the state of the lock 100 or whether a malfunction has occurred. The detector may specifically be a sensor or a switch; more specifically, it may be a contact switch such as a microswitch or a non-contact switch such as a photoelectric switch. If the detector is a contact switch, it is triggered when a target component comes into contact with the detector; if it is a non-contact switch, it is triggered when a target component enters its detection range. The lock 100 also includes a controller (which may be located outside the lock housing 101 and is not specifically shown), which is communicatively connected to the detector to receive signals from it.

[0058] In one embodiment, the lock 100 includes a first detector 210, which is installed inside the lock housing 101 and spaced apart at one end of the main body 206. The abutment block 207 is movable to a position that can trigger the first detector 210 (e.g., Figure 5 As shown), the abutment block 207 pushes the connecting member 105 to move, thereby releasing the abutment between the first abutment part 201 and the locking tongue. Specifically, refer to the following in sequence. Figure 4 and Figure 5 When the lower end of the movable rod 205 extends and the abutment block 207 abuts against the first detector 210, the first detector 210 is triggered, and the abutment between the first abutment part 201 and the locking tongue 104 is released; during this process, the abutment block 207 pushes the connecting member 105 to rotate clockwise. The user can determine whether the drive member 106 has moved normally to the required position when unlocking is required by whether the controller receives the signal generated by the triggering of the first detector 210.

[0059] Similarly, in one embodiment, the lock 100 includes a second detector 208, which is mounted inside the lock housing 101 and can be triggered by the bolt 104. For example, see... Figure 4 The side of the second protrusion 214 opposite to the first protrusion 213 abuts against the second detector 208, thereby triggering the second detector 208. The user can determine the position of the bolt 104 by whether the controller receives a signal generated by the triggering of the second detector 208, thereby determining the operating status of the lock 100.

[0060] When the lock 100 includes a second detector 208, the second detector 208 is communicatively connected to the drive member 106. The drive member 106 can operate when the second detector 208 is triggered by the bolt 104 (meaning when the second detector 208 switches from a non-triggered state to a triggered state), thereby causing the connecting member 105 to move and restoring the first abutment 201's abutment against the bolt 104. This enables the drive member 106 to automatically drive the connecting member 105 to move after the bolt 104 resets, thereby automatically restoring the locked state.

[0061] Similarly, refer to Figure 4 In one embodiment, the lock 100 includes a third detector 209, which is installed inside the lock housing 101. When the first abutment portion 201 abuts against the bolt 104, the connector 105 triggers the third detector 209. Specifically, the connector 105 includes a trigger portion 303, which is connected to the side of the second end (the second abutment portion 202). The trigger portion 303 is used to abut against and trigger the third detector 209. The user can determine the position of the connector 105 by whether the controller receives a signal generated by the triggering of the third detector 209.

[0062] The present invention also provides a medical cabinet 400, which includes a cabinet body 401, a cabinet door 402, and a lock 100 as described in any of the above embodiments.

[0063] The cabinet body 401 has an internal cavity (not specifically shown) for storing medicines, medical consumables, and other items. The cabinet door 402 closes this cavity. The cabinet door 402 is movably connected to the cabinet body 401, either by hinges or by sliding. One of the lock housing 101 and the lock ring 102 is mounted on the cabinet door 402, and the other is mounted on the cabinet body 401. For example, the lock housing 101 is mounted on the cabinet body 401, and the lock ring 102 is mounted on the cabinet door 402. Alternatively, in some embodiments, the lock housing 101 is mounted on the cabinet door 402, and the lock ring 102 is mounted on the cabinet body 401. Figure 7 Lock 100 is not specifically shown in the text; Figure 7 The medical cabinet 400 has a lock housing 101 installed inside the cabinet body 401. Figure 7 The dashed box in the middle corresponds to the approximate installation position of lock case 101; Figure 7 In the middle, the locking ring 102 can be installed on the left edge of the cabinet door 402.

[0064] When the cabinet door 402 covers the receiving cavity, the latch 104 can connect with the locking ring 102, thus preventing the cabinet door 402 from opening. When it is necessary to open the door, the drive member 106 releases the obstruction between the connecting member 105 and the latch 104, thereby allowing the latch 104 to rotate. After the latch 104 can rotate, the user can open the cabinet door 402. Due to the high security of the lock 100, the medical cabinet 400 of the present invention also has high security, and items inside the medical cabinet 400 are less likely to be lost or stolen.

[0065] Reference Figure 7 The medical cabinet 400 also includes an input device 403, which is communicatively connected to the driver 106. The input device 403 allows the user to input unlocking information. The unlocking information can be a character password, fingerprint, voice, etc. When the information input by the user matches the preset unlocking information in the input device 403, the driver 106 drives the lock 100 to unlock.

[0066] In one embodiment, the medical cabinet 400 also includes an emergency unlocking mechanism, primarily used for unlocking in case of a malfunction of the drive unit 106 or the input device 403. The emergency unlocking mechanism includes a lock cylinder and a linkage (neither specifically shown). The lock cylinder is mounted on the cabinet body 401 or the cabinet door 402 and is used for key insertion. The linkage can be a rod or a rope. Both ends of the linkage are connected to the lock cylinder and the connecting member 105, respectively. Specifically, the linkage can be connected to the second end (second abutment 202) of the connecting member 105. When the key is inserted into the lock cylinder, the lock cylinder can rotate relative to the cabinet body 401 or the cabinet door 402. Furthermore, when the lock cylinder rotates, it pulls the linkage, which in turn pulls the connecting member 105 located at the other end of the linkage, causing the connecting member 105 to rotate (based on...). Figure 4 (This will cause the connector 105 to rotate clockwise) and unlock the lock 100.

[0067] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
