Description

  The present invention relates to a door opening / closing device in a cabinet, and more particularly to a door opening / closing device in a cabinet that controls opening / closing of a door provided with a locking mechanism.

  2. Description of the Related Art Conventionally, various types of cabinets are provided that include a door that is openable and closable at a front opening of a housing, a handle, a mechanical lock, and a latch that is engaged with and disengaged from the collar of the housing in conjunction with the handle. A normal locking device has a structure in which a dead bolt protrudes directly from the edge of a door by a locking operation of a mechanical lock, and is inserted into an opening formed in a flange of the housing, or from a dead bolt of a mechanical lock to a flange of the housing. When there is a distance, a structure in which a locking rod provided so as to be slidable inside the door is interlocked with the dead bolt and protrudes up and down is generally used, and is independent of the latch. In this case, two systems of a latch driving mechanism and a locking rod driving mechanism are required, resulting in high costs.

  As an improvement measure, in Patent Document 1, a pressing block for hooking a finger inside the handle frame is provided so as to be slidable in the lateral direction, and a protrusion is formed on the side surface of the tip of the pressing block. An actuating tool is provided so as to be slidable in the vertical direction along the axis, a cutout portion capable of receiving the protrusion of the pressing block is provided on a side surface of the actuating tool, and an operating piece of the lock provided in the pulling frame The actuator is slid and driven in the unlocked state, and in the unlocked state, the position of the protrusion and the notch is made to coincide, the pressing block is slid and the shaft is rotated via the interlocking mechanism, and the end of the shaft The latch fixed to the release direction can be rotated in the unlocked state, the positions of the protrusion and the notch are shifted in the locked state, the protrusion abuts against the side edge of the operating tool, and the displacement of the pressing block is restricted, Mo Structure to maintain the engagement state of the latch is disclosed.

  However, since the operating tool is a slide guide mechanism using a mounting tool such as a long hole and a screw on the back of the surface plate of the door, and the operating tool is made of a flat plate material, the operating tool can be slid. It is assumed that it is unstable and wobbles, and if the pressing block is pulled strongly in the locked state, the operating tool may be deformed, and the latch may rotate to disengage the engagement with the collar. In addition, the handle frame and the operating tool are mounted at different positions, and the lock is mounted in the handle frame made of synthetic resin, but is provided on the back part of the handle plate part of the handle frame. I cannot deny that they are vulnerable.

  Further, in Patent Document 2, a pulling handle in which two rotating pieces protrude in a V-shaped cross section are provided in a pulling case provided on a door in parallel with a latch shaft, and an interlocking piece is provided on the shaft. In addition, an interlocking member formed with a long groove into which a dead bolt of the cylinder lock is fitted is fixed, and the other rotating piece is engaged with the interlocking piece of the interlocking member by pushing the one rotating piece of the puller. The door locking device is held so that the shaft can be rotated and the shaft can not be rotated by inserting the end of the dead bolt, which is defined by the locking operation of the slender lock, into the long groove of the interlocking member. .

  However, since the thing of patent document 2 is a structure which controls rotation of a shaft at the time of locking, when it tries to operate a pulling handle compulsorily in a locked state, a load is applied to a shaft, Therefore The demand for the rigidity of a shaft is required. The strength is required to be high and not to be damaged even if a large force is applied to the interlocking piece of the interlocking member or the turning piece of the pulling handle. In addition, when the door is locked in an open state, such as when an electric lock is mounted, the shaft is fixed, so that it is impossible to kick the latch into the engagement hole of the housing and engage it.

Here, examples of the authentication pattern in the authentication unit 110 include touch authentication that is input by touching the touch panel with a finger and card authentication using an IC card. Touch authentication includes one-touch authentication and gesture authentication, and there is also authentication that combines these with card authentication.

  The solenoid 109 applies a magnetic force generated by passing an electric current through an electromagnetic coil to linearly move a plunger (movable iron core). There are two types of solenoids, a push type that pushes the plunger from the coil part, a pull type that pulls the plunger from the coil part, and two coils depending on the structure in which the coil part acts on the movable part. However, there is a push-pull type structure that uses two coils for pressing and suction, but in this embodiment, a general pull type is used.

  First, as shown in FIGS. 17, 18, and 22, the door 102 has a surface plate 115 that is bent to the back side to form an edge plate 116, and the upper surface and both side surfaces are further inward. The reinforcing plate 117 is bent, and the inner edge of the reinforcing plate 117 is bent toward the surface plate 115 to form the bent plate 118. A handle opening 119 is formed on the side plate 115 of the door 102 on the side edge on the free end side so that the handle 103 and the authentication means 110 incorporated in the operation unit 108 appear on the front side. doing. As shown in FIG. 22, the pulling opening 119 is formed by subjecting the front plate 115 to the back side, and a mounting bracket 120 having a substantially rectangular shape in front view is spot-welded to the surrounding back surface. The support plate 122 for mounting the back cover 113 on the side opposite to the free end side of the door 102 and the engagement plate 121 erected at right angles along the inner peripheral edge of the mounting bracket 120 are erected at right angles. . The operation unit 108 engages an engagement step portion 123 formed at one end with a bent plate 118 on the free end side of the door 102 and engages the engagement plate 121 with an elastic claw 124 to prevent it from coming off.

In addition, the back cover 113 engages the fitting portion 125 on one side end with the bent plate 118 on the free end side of the door 102, and the side plate 126 on the other side outside the support plate 122. Then, the operation unit 108 is covered with a screw.

  Before the operation unit 108 is fitted to the back side of the door 102, a latch drive mechanism 114 for interlocking the latch 105 with the handle 103 is attached to the back end side of the door 102. The latch drive mechanism 114 includes a shaft 127 disposed along the free end side of the door 102, an interlocking member 128 that is non-rotatably fitted to the shaft 127 at an intermediate position of the shaft 127, and the latch 105. It comprises a latch receiving member 129 that is movably supported and is attached to the free end corner portion of the door 102. The end portion of the shaft 127 is fitted to the shaft portion of the latch 105 so as not to rotate. The shaft 127 is a square bar, the interlocking member 128 is fitted from the side of the shaft 127, and the shaft portion of the latch 105 is fitted from the axial direction. Here, at the same time that the operation unit 108 is fitted to the back side of the door 102, the shaft 127 is received inside the operation unit 108, the handle 103 and the interlocking member 128 are linked, and the handle 103 is moved forward. The latch 105 is rotated in the direction in which the engagement with the engagement holes of the upper and lower flange portions of the housing 101 is released via the latch drive mechanism 114 by the pulling operation. The latch receiving member 129 is a substantially L-shaped member when viewed from the front, and is fitted to both sides with the corner portion of the door 102 interposed therebetween, that is, it contacts the back surface of the surface plate 115 and both edge plates 116 and 116. The door 102 is engaged with both bent plates 118 and 118, and both sides of the door 102 are integrated, and the casing 101 is shaken and deformed by an earthquake, and even if a large force is applied to the latch 105, the door The deformation of the edge portion 102, particularly the upper and lower edge portions is suppressed.

  Next, the locking mechanism and the linkage between the pull handle 103 and the latch drive mechanism 114 will be described with reference to FIGS. The locking mechanism, which is a main part of the door locking means 104 according to the present invention, arranges the finger hook portion 130 of the pull handle 103 so as to face the pull opening 119 formed in the surface plate 115 of the door 102, and the finger hook The front end portion of the arm portion 131 extending from the portion 130 is pivotally supported at a position on the back side of the surface plate 115 so as to be in contact with the surface plate 115 between the intermediate portion of the arm portion 131 and the surface plate 115. And a regulating member 132 that is slidably displaced in a direction parallel to the central axis of rotation of the handle 103 by the locking / unlocking operation of the electric lock 106, and has a convex portion 133 and a concave portion 134 in the middle portion of the arm portion 131. And a relief recess 135 that accepts the projection 133 of the arm portion 131 in the unlocked state to permit the rotation of the pull handle 103 and the arm in the locked state. Those locks the convex portion 133 of the arm portion 131 is characterized in that the formation of the limiting protrusion 136 for restricting the rotation of the tab 103.

  As shown in FIGS. 19 and 22, the puller 103 has a surface in which the finger hook 130 is smoothly curved. Since the finger hook portion 130 is retracted toward the back and increases in thickness from the surface, when the handle 103 is integrally formed of a synthetic resin, the front side meat is removed for molding. Ribs must be formed. Therefore, in the present embodiment, the front surface of the finger hook 130 is fitted with a decorative member 137 formed of a separate member so that the front surface is flat. When the puller 103 is mounted in the puller mounting space 138 of the operation unit 108, only the decorative member 137 is visible from the front side. The remaining space after the puller 103 is mounted in the puller mounting space 138 becomes the finger insertion space 112.

  More specifically, a plurality of the convex portions 133 and the concave portions 134 are alternately formed at regular intervals in a direction parallel to the rotation center axis of the puller 103 at the intermediate portion of the arm portion 131 of the puller 103, and the restriction member A plurality of restriction convex portions 136 and a plurality of relief concave portions 135 are alternately formed at regular intervals in the sliding direction of the regulating member 132 on the side opposite to the sliding surface 139 of the 132 with respect to the surface plate 115. In the present embodiment, the convex portion 133 of the arm portion 131 of the pull handle 103 and the restricting convex portion 136 of the restricting member 132 are formed at three locations, and there are four concave portions 134 and relief concave portions 135 between both sides thereof. Is formed.

  As shown in FIGS. 19, 21, and 30, the main body case portion 140 of the operation unit 108 protrudes from both sides of the distal end of the arm portion 131 of the puller 103 at a position continuous from the puller mounting space 138. The bearings 142 and 142 are formed to rotatably support the support shafts 141 and 141. The support shafts 141 and 141 are forcibly fitted to the bearing portions 142 and 142 to be pivotally supported. The restricting member 132 loosely inserts a linear control portion 143 along the surface plate 115 of the door 102 into guide grooves 145 and 145 formed in a pulling frame portion 144 of the main body case portion 140 of the operation unit 108. A linking portion 146 which is surrounded by the surface plate 115 and supported so as to be slidable and extends from the control portion 143 in a crank shape is connected to the linking tool 147 by a rotary joint structure. The linkage 147 is a member operated by the electric lock 106 and the mechanical lock 107 as will be described later. That is, the cam member 149 is rotated in conjunction with the plunger 148 of the solenoid 109 that is linearly driven in accordance with the locking / unlocking operation of the electric lock 106, and the regulating member 132 is moved by the rotational displacement of the cam member 149. By sliding displacement, the positions of the convex part 133 and the concave part 134 are changed with respect to the regulating convex part 136 and the relief concave part 135 of the pull handle 103.

  Here, as shown in FIG. 19, the handle frame portion 144 is provided in the central portion of the main body case portion 140 of the operation unit 108, and the solenoid 109, the mechanical lock 107, and the linkage device of the electric lock 106 are provided on the upper portion. 147, a mechanism housing portion 150 for storing the locking mechanism portion (driving portion) of the locking means 104 such as the cam member 149 is formed, and a control portion housing portion for storing the authentication means 110 of the electric lock 106 and the control circuit in the lower part. 151 is integrally formed. Of course, the positional relationship among the handle frame portion 144, the mechanism portion accommodating portion 150, and the control portion accommodating portion 151 is changed vertically and horizontally depending on the direction in which the main body case portion 140 of the operation unit 108 is attached, but the handle 103 is attached. It is common that the mechanism housing portion 150 is disposed on one side and the control portion housing portion 151 is disposed on the other side with the handle frame portion 144 interposed therebetween. Here, the battery unit for supplying power to the electric lock 106 is attached to the back surface of the outer surface plate 115 of the main body case portion 140 by an appropriate means, but is accommodated in the control portion accommodating portion 151. It is also possible. The solenoid 109, the mechanical lock 107, the linkage 147, the cam member 149, and the like are incorporated in the drive unit storage container 152 in advance as shown in FIGS. It fits in the part accommodating part 150. Here, the puller 103 is formed symmetrically with respect to the center line, and the regulating member 132 is reversed and used even when the position of the mechanism accommodating portion 150 provided in the main body case portion 140 of the operation unit 108 is reversed. As can be seen, the relationship between the convex portion 133 and the concave portion 134, and the restriction convex portion 136 and the relief concave portion 135 are symmetrical even if they are reversed.

  Next, the linkage between the handle 103 and the latch drive mechanism 114 will be described. The latch 105 is fixed to the end portion, and an interlocking member 128 is integrally provided with respect to the rotation at an intermediate position of the shaft 127 that is rotatably attached to the back surface of the surface plate 115 of the door 102. The interlocking piece 153 provided on the side is continuously in contact with the operation protrusion 154 extending in a direction parallel to the rotation center axis of the puller 103 continuously to the convex portion 133 formed on the arm portion 131 of the puller 103. However, you may make it contact | abut at the time of pulling operation.

  The handle 103 is rotatably provided in the main body case portion 140 of the operation unit 108, the locking means 104 and the regulating member 132 are incorporated, and the rotation center axis and the front side of the arm portion 131 of the handle 103 are arranged. An arch-shaped recessed portion 155 is provided between the protruding portion 133 and a U-shaped recessed portion 156 that is open to the front surface side is formed in the main body case portion 140 on the extension line. When attaching to the back surface of the face plate 115, the shaft 127 is received in the U-shaped recess 156 of the main body case portion 140 and the interlocking member 128 is received in the recess 155 of the puller 103, and at the same time, the interlocking piece 153 is received in the arm portion. It is in contact with the operation protrusion 154 of 131.

  At both ends of the interlocking member 128, pressing pieces 157 and 157 are provided on the side opposite to the side where the interlocking piece 153 is provided, and a compression coil spring 158 is attached to the tip of the pressing piece 157, When the operation unit 108 is attached to the back surface of the door 102, a compression coil spring 158 is abutted in a compressed state on a retaining surface 159 provided in the vicinity of the U-shaped recess 156 of the main body case 140, and the interlocking piece 153 Is elastically biased in the direction in which the operation protrusion 154 of the puller 103 is pressed. That is, the latch 105 is elastically biased in a direction in which the latch 105 is engaged with the engagement hole of the flange portion of the housing 101.

  Further, in the main body case portion 140 of the operation unit 108, a key hole 111 of the mechanical lock 107 is provided on the side surface of the handle frame portion 144 between the handle attachment space 138 and the mechanism housing portion 150. The opening 160 is formed so as to face. That is, as shown in FIG. 18, the key hole 111 is provided in the upper surface portion of the finger insertion space 112 hidden from the line of sight, and the key 161 inserted into the finger insertion space 112 is engaged with the key hole 111 to thereby When the locking / unlocking operation of 107 is performed, the dead bolt 162 of the mechanical lock 107 is linearly driven.

  The locking means 104 has a structure for controlling the opening and closing of the door 102 by displacing a regulating member 132 linked in contact with a drive unit that is displaced by a locking / unlocking operation of the electric lock 106 via a linkage 147. When the locking / unlocking mechanism and the electric lock 106 become unusable in the locked state, the regulating member 132 is released regardless of the electric lock 106 by the dead bolt 162 of the mechanical lock 107 to be unlocked. An emergency unlocking mechanism forcibly displacing in the locking direction.

  The electric lock 106 includes a solenoid 109 and an authentication unit 110 that issues an energization / non-energization command to the solenoid 109. When the solenoid 109 is de-energized, the plunger 148 is projected or retracted by an elastic biasing force. The plunger 148 is displaced in the reverse direction against the elastic biasing force when energized, and is in the unlocked state, and the regulating member 132 is elastically biased in the direction of the locked state. The linkage mechanism of the restricting member 132 and the plunger 148 is structured to be released when it is displaced in the unlocking direction by the dead bolt 162 of the mechanical lock 107.

  The solenoid 109 is a pull type that pulls the plunger 148 against an elastic biasing force when energized, and the linkage mechanism operates a cam member 149 that converts a linear motion into a rotational motion when the plunger 148 is retracted. When the piece 163 is abutted against the locking portion 164 of the linkage 147 connected to the restriction member 132 by the elastic biasing force of the restriction member 132, and the dead bolt 162 is displaced by operating the mechanical lock 107. In addition, an emergency linkage mechanism that displaces the locking member 164 of the linkage tool 147 away from the operating piece 163 against the elastic urging force of the regulating member 132 is provided. Here, the emergency linkage mechanism is configured such that the tip sliding portion 165 of the dead bolt 162 that moves linearly is brought into pressure contact with the inclined surface 166 formed on the side surface of the linkage tool 147 connected to the restriction member 132, In this structure, the surface 166 is displaced in the direction of escaping from the tip sliding portion 165.

More specifically, as shown in FIGS. 24 and 25, the solenoid 109 and the mechanical lock 107 are stored in the drive unit storage container 152 with the drive directions of the plunger 148 and the dead bolt 162 being parallel, The linkage tool 147 is slidably held in the direction orthogonal to the driving direction on the distal ends of the plunger 148 and the dead bolt 162. The cam member 149 is a substantially L-shaped member when viewed from the front, and has a central portion rotatably supported by a support shaft 167 protruding from the inside of the drive unit storage container 152, and one end portion of the cam member 149. Is the operating piece 163, and the other end is a driving piece 168 that is rotatably connected to the tip of the plunger 148. The drive piece 168 and the plunger 148 are connected by forming a slit groove 169 in the diameter direction at the distal end portion of the plunger 148, and inserting a pin 170 so as to cross the slit groove 169. This is a structure in which the engaging groove 171 opened at the tip of the driving piece 168 is engaged with the pin 70 by loosely inserting the portion into the slit groove 169.

  The plunger 148 has a compression coil spring 174 wound between a main body 172 of the solenoid 109 and a locking ring 173 such as an E-ring that is attached to the tip, and is elastically applied in a direction in which the plunger 148 protrudes. It is fast. Further, a compression coil spring 175 is interposed between the proximal end portion of the linkage tool 147 and the inner wall of the drive unit storage container 152, and elastically biased in a direction in which the linkage tool 147 protrudes from the drive unit storage container 152. ing. The inclined surface 166 is formed at a tip portion of the linkage tool 147 so as to incline toward the tip side, and the linkage portion 146 of the regulating member 132 is formed at the tip portion of the linkage tool 147. They are connected by a rotating joint structure. As shown in FIGS. 24, 25 and 28, this rotary joint structure has two dowels 177 and 177 projecting in the diametrical direction at the tip of a shaft portion 176 provided on the tip of the linkage 147. On the other hand, an insertion hole 178 that matches the outer shape of the shaft portion 176 and the dowels 177 and 177 is formed in the linkage portion 146 of the restriction member 132, and the shaft portion 176 and the dowels 177 and 177 are inserted into the insertion hole 178. In the state where the dowels 177 and 177 penetrate the insertion hole 178, the restriction member 132 is rotated by 90 ° and used in a state in which it is prevented from coming off. Since the linking tool 147 and the regulating member 132 are used by being connected linearly, they are formed so that they can be inserted in a direction different from the direction by 90 °.

  Further, the tip of the dead bolt 162 of the mechanical lock 107 is a tip sliding portion 165 slidably contacting the inclined surface 166 of the linkage 147. Specifically, the tip sliding portion 165 is the inclined surface. It is formed with an inclined surface having the same inclination as 166. The tip of the dead bolt 162 may be bent to form the tip sliding portion 165.

  First, in order to make the unlocked state using the electric lock 106, a reef number is input to the authentication means 110 on the surface side of the door 102, and when the solenoid 109 is energized in response to a command from the control circuit, The plunger 148 is pulled toward the main body 172 against the elastic biasing force of the compression coil spring 174, rotates the cam member 149 in the clockwise direction in FIG. 24A, and the operating piece 163 moves to the linkage 147. In a state where it is in contact with the locking portion 164, the linking tool 147 is slid and displaced so as to be pulled into the drive portion storage container 152 against the elastic biasing force of the compression coil spring 175. Naturally, the restricting member 132 is slid in the same manner as the slide displacement of the linkage 147, and the position of the restricting convex portion 136 of the restricting member 132 and the convex portion 133 of the arm portion 131 of the puller 103 is shifted. 103 can be pulled and rotated, whereby the interlocking piece 153 of the interlocking member 128 of the latch driving mechanism 114 is pushed by the operation projection 154, the shaft 127 is rotated, the latch 105 is rotated, and the casing 101 is rotated. The door 102 can be opened by releasing the engagement with the collar.

  Then, when the energization to the solenoid 109 is cut off, the plunger 148 protrudes by the elastic biasing force of the compression coil spring 174, and the linkage 147 is removed from the drive unit storage container 152 by the elastic biasing force of the compression coil spring 175. The protrusion protrudes and returns to the initial state, and the position of the restricting convex portion 136 of the restricting member 132 and the position of the convex portion 133 of the arm portion 131 of the pull handle 103 coincide with each other. Since the restricting member 132 is sandwiched between them, further rotation is restricted, so that the latch 105 is maintained in engagement with the flange portion of the casing 101, and the locking means 104 is locked.

  Here, when the solenoid 109 cannot be energized due to some failure such as battery exhaustion, that is, when the door 102 needs to be opened in an emergency, the key 161 is inserted into the key hole 111 from the finger insertion space 112 and the mechanical lock is inserted. When the 107 is rotated to the unlocked state, the dead bolt 162 protrudes in the direction of the arrow in FIG. 24B, the tip sliding portion 165 presses the inclined surface 166 of the linkage 147, and the inclined surface 166 is retracted. The force acts in the direction in which the linkage tool 147 is pulled into the drive unit storage container 152, and the link tool 147 moves against the elastic biasing force of the compression coil spring 175. In the same manner as when the solenoid 109 is energized and the solenoid 109 is energized, the restricting member 132 can be slid to the unlocked state, 03 now can be subtracted in front, by rotating the latch 105 can open the door 102 to release the engagement with rail portion of the housing 101. At this time, the locking portion 164 of the linkage tool 147 moves away from the operating piece 163 of the cam member 149 and operates independently of the cam member 149.

  Further, when the key 161 is operated to lock from the emergency unlocked state, the dead bolt 162 is retracted in the opposite direction, and the linkage 147 protrudes from the drive unit storage container 152 by the elastic biasing force of the compression coil spring 175. The slide member is also displaced, and the restricting member 132 is similarly slid to return to the initial state, and the locking means 104 enters the locked state.

  As shown in FIG. 25, the drive unit storage container 152 includes a main body container 179 and a lid 180. The main body container 179 includes the solenoid 109, the mechanical lock 107, the linkage 147, the cam member 149, the compression coil spring 175, and the like. These parts are incorporated, and the lid 180 is fitted in a deadly manner. As shown in FIG. 29, the drive unit storage container 152 assembled in this way is fitted into the mechanism unit accommodating unit 150 of the operation unit 108 to incorporate the locking means 104 therein.

  As described above, the handle frame portion 144 is provided in the central portion of the main body case portion 140 of the operation unit 108, the mechanism portion accommodating portion 150 is accommodated on one side of the handle frame portion 144, and the control portion is accommodated on the other side. Although the solenoid 151 is accommodated in the mechanism accommodating portion 150 and the authentication unit 110 and the control circuit are accommodated in the control portion accommodating portion 151, the main body case portion 140 is electrically connected. A function for hooking a code (not shown) connecting the solenoid 109 of the lock 106 and the authentication means 110 is provided. That is, as shown in FIGS. 29 and 30, a plurality of cord hooks 181,... Are provided on the outer side surface of the main body case portion 140.
