Abstract
Description
- The present invention relates to a door clamping lock system used in boxes and like containers for receiving therein electric instruments, communication instruments and like instruments.
- It has been known to dispose a packing member between an opening portion of a box body and a door for the purpose of sealing up, i.e. strictly cutting off the interior space, of the box body from the outside space.
- In use, however, it is very difficult to uniformly compress the packing member over its entire length. Although it has been proposed to provide a plurality of clamping members along the length of the packing member, this requires simultaneous clamping operations of these clamping members.
- When some of these clamping members are ahead of the remaining ones in clamping operations, unclamped portions of the packing member corresponding to such remaining clamping members receive expelled parts of already clamped portions of the packing member, so that the unclamped portions of the packing member bulge out of their positions to prevent the door from being neatly closed, which prevents a latch of the clamping member from engaging with a corresponding socket member of the box
- In view of the above, another proposal has been made, in which: a turning-point transmission unit is disposed in each of the corner portions of the door; through these turning-point transmission units,a plurality of vertical and lateral rods are connected with each other to form a chain-like assembly to cover the entire peripheral portion of the door; and a plurality of hook members are fixedly mounted on several portions of the vertical and the lateral rods; whereby, when the door is closed, a plurality of catch roller units fixedly mounted on the box body are simultaneously drawn aside by these hook members to compress the packing member between the door and the box body.
- In this proposal, however, a resilient force; exerted by the thus compressed packing member directly acts on the hook members and therefore on both the vertical and the lateral rods on which the hook members are fixed, so that both the hook members and these rods cause considerable deforming resulting in permanent deformations of both the hook members and these rods after several times of use of the door. Such deformations often make it impossible to lock the door.
- Further, in the case that the vertical and the lateral rods forming such chain-like assembly are moved forward to reach their locking positions so that the hook members are placed in their locking positions by mistake in a condition in which the door is opened, when the door is closed, the hook members are hit by the catch roller units, which often damages the hook members and the catch roller units themselves.
- Consequently, it is an object of the present invention to provide a door clamping lock system, which is free from any risk that, in a locking operation of a door, a plurality of vertical and lateral rods on which a plurality of hook members are fixedly mounted cause deforming, and also free from any risk that the hook members are subjected to shearing forces, or cause deforming, whereby a packing member is substantially uniformly compressed between the door and a box body.
- It is another object of the present invention to provide a door clamping lock system which is capable of holding both the vertical and the lateral rods in their clamping-lock release positions without fail so as to prevent both the catch roller units and the hook members from being damaged.
- According to a first aspect of the present invention, the above objects of the present invention are accomplished by providing:
- A door clamping lock system comprising:
- a box body on which a catch roller unit is fixedly mounted;
- a door on which a guide roller unit is fixedly mounted;
- a packing member disposed between the box body and the door;
- a right and a left vertical rod disposed in the right and the left side of the door, respectively;
- an upper and a lower lateral rod disposed in the upper and the lower side of the door, respectively;
- a pinion gear interlocked with a lock handle member, the pinion gear engaging with a rack portion provided in at least one of the vertical rods or one of the lateral rods;
- a turning-point transmission unit, which is fixedly mounted on each of corner portions of the door and provided with a connecting bar through which the vertical rods and the lateral rods are connected with each other to form a chain-like assembly; and
- a hook member fixedly mounted on each of the vertical rods
and each of the lateral rods, the hook member being provided with
a hook portion which has a cam surface capable of drawing aside
the catch roller unit when the door is locked, the hook member
being further provided with a slot portion which receives the
guide roller unit therein;
wherein, when the pinion gear is rotated in operation to move both the vertical rods and the lateral rods, the catch roller unit is caught and drawn aside by the hook portion of the hook member so that the packing member is compressed between the door and the body box. -
- According to a second aspect of the present invention, the above objects of the present invention are accomplished by providing:
- The door clamping Lock system as set forth in the first aspect of the present invention, further comprising:
- a stop pin provided in at least one of the vertical rods or one of the lateral rods;
- a check lever member pivotally mounted on the door by means of a pivot, the check lever member being rotatably biased by a spring so as to have its front end portion abut against the periphery of the stop pin; and
- a release pin for releasing the check lever member from the stop pin by pushing a side surface of the check lever member at the end of a closing operation of the door, the release pin being fixedly mounted on the box body.

- Now, the present invention will be described in detail using its preferred embodiments with reference to the accompanying drawings.
- According to a first aspect of the present invention, in a door clamping lock system of an embodiment of the present invention: a right and a left
vertical rod 2 are disposed in the right and the left side of a door 1, respectively; an upper and a lowerlateral rod 3 are disposed in the upper and the lower side of the door 1, respectively; a turning-point transmission unit 4 is fixedly mounted on each of the corner portions of the door 1 and provided with a connectingbar 5 through which thevertical rods 2 and thelateral rods 3 are connected with each other to form a chain-like assembly; and ahook member 8 is fixedly mounted on each of thevertical rods 2 and each of thelateral rods 3. - The
hook member 8 is provided with ahook portion 8a. Thisportion 8a has acam surface 8c capable of drawing aside acatch roller unit 7 when the door 1 is locked, wherein thecatch roller unit 7 is fixedly mounted on abox body 6. - Further, the
hook member 8 is provided with aslot portion 8b which receives therein aguide roller unit 9 fixedly mounted on the door 1. Further, a pinion gear 11 is mechanically interlocked with alock handle member 10, and engages with arack portion 12 which is provided in at least one of thevertical rods 2 or one of thelateral rods 3. - An operating force is transmitted from the pinion gear 11 of the
lock handle member 10 to therack portion 12 of each of therods packing member 16 is disposed between thebox body 6 and the door 1. - In a door clamping and locking operation, when the pinion gear 11 is rotated by means of a locking shaft of the
lock handle member 10, since the pinion gear 11 is meshed with therack portion 12 of each of therods vertical rods 2 and thelateral rods 3 are moved forward to their clamping and locking positions. - At this time, as these
rods hook members 8 of theserods slot portions 8b slidably guided by theguide roller units 9, and move toward thecatch roller units 7. At the end of this movement, thecatch roller units 7 are drawn aside by thecam surfaces 8c of thehook members 8, so that thecatch roller units 7 are deeply engaged with thehook portions 8a of thehook members 8. - As described above, in a process for catching and drawing aside the
catch roller units 7 by means of thehook members 8, when the door 1 is pulled so as to move to its locking position parallel to itself relative to thebox body 6, thepacking member 16 is uniformly compressed over its entire length between the door 1 and thebox body 6. - According to a second aspect of the present invention, the door clamping lock system as set forth in the first aspect of the present invention further comprises:
- a
stop pin 17 provided in at least one of thevertical rods 2 or one of thelateral rods 3; - a
check lever member 19 pivotally mounted on the door 1 by means of apivot 18, thecheck lever member 19 being rotatably biased by aspring 20 so as to have its front end portion 19a abut against the periphery of thestop pin 17; and - a
release pin 21 for releasing thecheck lever member 19 from thestop pin 17 by pushing a side surface of thecheck lever member 19 at the end of a closing operation of the door 1, therelease pin 21 being fixedly mounted on thebox body 6. -
- In an unlocking operation, the pinion gear 11 is reversed in rotation by means of the
lock handle unit 10, so that thevertical rods 2 and thelateral rods 3 are moved rearward to their unclamping and unlocking positions. - At this time, the
catch roller units 7 are disengaged from thehook portions 8a of thehook members 3 of theserods hook member 8 is separated from thecatch roller unit 7 by a predetermined distance, thecheck lever member 19 is rotatably driven by thespring 20 and has its front end portion 19a abut against the periphery of thestop pin 17, which prevents both thevertical rods 2 and thelateral rods 3 from moving in the direction of the arrow (shown in Fig. 14) toward their locking positions, so that thehook members 8 are held in their unlocking (i.e., lock-release) positions. - In a condition in which the door 1 is opened, the
vertical rods 2 and thelateral rods 3 both forming the chain-like assembly are prevented from moving by means of both thestop pin 17 and thecheck lever member 19. - Under such circumstances, when the door 1 is closed, at the end of this door closing operation, the
release pin 21 pushes the side surface of thecheck lever member 19 to rotate thesame member 19 about thepivot 18 against a resilient force exerted by thespring 20. Due to this rotational movement of thecheck lever member 19, thecheck lever member 19 is disengaged or released from thestop pin 17, which permits thevertical rods 2 and thelateral rods 3 to move forward to their locking positions, and thereby permitting thelock handle unit 10 to be used. - In the embodiment of the present invention shown in the drawings, the left and the right
vertical rods 2 are disposed inside the door 1 together with the upper and the lowerlateral rods 3. On the other hand, thelock handle unit 10 is of a pull-out swinging operation type, and embedded and fixedly mounted in a front surface of the door 1. - The pinion gear 11 is mechanically interlocked with the locking shaft of the
lock handle unit 10, and meshed with therack portion 12 of thevertical rod 2, as shown in Fig. 11. Therack portion 12 is constructed of a series of lateral openings or slots provided at predetermined intervals corresponding to the pitch of the pinion gear 11. Theslot portion 8b of thehook member 8 assumes an elongated shape extending the length of each of thevertical rods 2 and thelateral rods 3. - The
vertical rods 2,lateral rods 3, turning-point transmission units 4 and the connectingbars 5 are connected in series with each other under tension without permitting any slackness. The turning-point transmission units 4 is constructed of a pulley. - On the other hand, the connecting
bar 5 is constructed of an inextensible belt such as strips of metal and the like. As shown in Fig. 5, thelateral rod 3 is slidably received by aguide member 13, while thevertical rod 2 is slidably received by a pair of theguide members 13. Theguide member 13 is fixedly mounted on an inner surface of the door 1 to stabilize in motion thelateral rods 3 in the vertical direction and thevertical rods 2 in the lateral direction so as to prevent theserods - A
flange portion 14 extends around the opening portion of afront wall portion 6a of thebox body 6 so as to surround the opening portion. As is clear from Fig. 2, theflange portion 14 is formed so as to protrude forward from afront wall portion 6a of thebox body 6. - The door 1 assumes a flat box-like shape constructed of: a front wall portion 1a which is the same in both shape and size as a front surface outer contoured area of the
box body 6; and, a peripheral bent wall portion 1b which is bent four times along four sides of the front wall portion 1a so as to be integrated with the front wall portion 1a. The door 1 is supported by a pair ofhinge members 15 which are vertically spaced apart from each other along a right edge portion of thebox body 6 and fixedly mounted thereon. - The
hinge member 15 is constructed of: abase member 15a fixedly mounted on thebox body 6; asupport axle 15b vertically slidably mounted in thebase member 15a; anarm member 15c fixedly mounted on a front end portion of thesupport axle 15b; apivot 15d slidably received in a base end sleeve portion of thearm member 15c; abearing base 15e for supporting thepivot 15d; and, a compression coil spring 15f mounted on thesupport axle 15b in an insertion manner between thebase member 15a and the front end portion of thearm member 15c. - Since the door clamping lock system of the present invention has the above construction, after the door 1 is rotated on the
pivot 15d, it is possible for the door 1 to move to its locking position parallel to itself relative to thebox body 6 when thecatch roller units 7 are drawn aside by thehook members 8. - Adhesively applied and fixed to the entire periphery of a front surface of the end portion of the
flange portion 14 is the packingmember 16 which is made of rubber. It is also possible to provide the packingmember 16 in the side of the door 1. - Each of the
box body 6 and the door 1 is constructed of steel plates. - The
spring 20 for biasing thecheck lever member 19 is constructed of a torsion coil spring. Thespring 20 has its coiledportion 20a mounted aroundpin 22. Further, thespring 20 has one 20b of its oppositestraight end portions 20b, 20c abut against aspring support portion 24 of the door 1, and the other 20c abut against aspring support pin 23 which is fixedly mounted on the base end portion of thecheck lever member 19. - The effect of the present invention is as follows. Namely, as described above, in the door clamping lock system according to the first aspect of the present invention, in a condition in which the
vertical rods 2 and thelateral rods 3 forming the chain-like assembly are provided with a plurality of thehook members 8 each of which has itsslot portion 8b slidably receive therein theguide roller unit 9 fixedly mounted on the door 1, a plurality of thecatch roller units 7 provided in thebox body 6 are drawn aside by thehook portions 8a of thehook members 8 while being guided by means of the cam surfaces 8c of thehook members 8 in the door locking operation. - Consequently, it is possible to uniformly compress the packing
member 16 over its entire length between the door 1 and thebox body 6, which ensures that the interior space of thebox body 6 is excellent in gas-tight and water-tight properties when closed by the door 1. - Further, the
hook member 8 is center-balanced by both of: itshook portions 8a engaging with thecatch roller unit 7; and itsslot portion 8b engaging with theguide roller unit 9, so that shearing forces to which thevertical rods 2 and thelateral rods 3 are subjected are reduced. - Consequently, it is possible to sufficiently lock the door 1 without causing any deforming of the
vertical rods 2 and thelateral rods 3 and also without any risk that thehook members 8 are subjected to shearing forces and cause deforming. - Further, in the door clamping lock system of the present invention: the
stop pin 17 is provided in thevertical rod 2 or in thelateral rod 3; and, the front end portion 19a of thecheck lever member 19 pivotally mounted on the door 1 abuts against thestop pin 17 to prevent both thevertical rods 2 and thelateral rods 3 from moving forward to their locking positions in a condition in which the door 1 is opened, which makes it possible to prevent thecatch roller units 7 from hitting and damaging thehook members 8, without fail. - Further, at the end of the door locking operation, since the
