Description

  The present invention relates to an improvement of a door operation device that is attached to a door and is provided with a door operation body such as a door handle or a door knob.

  In a house entrance door or the like, if there is a pressure difference inside and outside the house due to ventilation, a relatively large force is often required to open it. If the space between the one side and the other side sandwiching the door is vented before the door is opened, the pressure difference can be corrected and the door can be easily opened.

As such a technique, there is one in which an airtight material that closes a gap between a door and a floor moves upward when a knob arranged in the vicinity of the door knob is operated. (See Patent Document 1)
In addition, there is a type in which a ventilating door that closes a ventilating opening provided at the lower part of the door by operating a doorknob is rotated to open the ventilating opening. (See Patent Document 2)
Further, there is a type in which when a push-pull lock provided on the door is operated, the inside and outside are ventilated by a pressure difference relaxation mechanism provided on the hinge side of the door. (See Patent Document 3)

However, all of these require a separate structure on the lower part of the door or on the side where the hinge is provided, as well as a link rod for operating a mechanism that ensures ventilation in conjunction with the operation of the door knob etc. Needed to be placed inside the door.

  The main problem to be solved by the present invention is to make it possible to easily and appropriately provide the door with a structure that corrects the situation in which the door is difficult to open due to a pressure difference caused by ventilation.

In order to achieve the above object, in the present invention, a door operation device is attached to a door and is provided with a door operation body such as a door handle.
Moved to the position of the device body equipped with a ventilation part that connects the space on one side and the other side across the door to the position where the opening of the door operation body is unlocked in conjunction with the operation to open the door. The ventilation member closing member is built in.

  According to such a configuration, it is possible to normally ensure the airtightness of the door by closing the ventilation portion with the closing member. On the other hand, when opening the door, even if there is a pressure difference between the space on one side and the other side where the door is sandwiched by opening the ventilation part, this pressure difference is triggered by the operation of the door operator. Can be reduced rapidly to reduce the force to open the door. In particular, the door operating device has an advantage that the above functions can be easily given to existing doors or existing doors.

  If the ventilation section is formed at a plurality of locations in the vertical direction or the horizontal direction in the apparatus main body, or continuously in the vertical direction or the horizontal direction in the apparatus main body, it is within the space of the door operation device combined with the door. The ventilation portion can be rationally formed in such a manner that the ventilation flow rate is increased as much as possible, and when there is the pressure difference triggered by the operation of the door operation body, this difference can be reduced rapidly.

  Further, if the entrance of the ventilation part is covered with a blindfold that is externally attached to the door by opening a ventilation gap with the outer surface of the door, the ventilation can be achieved while ensuring ventilation through the ventilation gap. It is possible to prevent the portion from affecting the appearance of the door.

  In addition, if the closing member moves in a direction crossing the ventilation direction of the ventilation portion in conjunction with the operation of opening the door of the door operation body to release the closure of the ventilation portion, When there is a pressure difference between the space on the side and the space on the other side, the closing member is relatively smooth compared to the case where the closing member is moved in the direction opposite to the direction of the force applied to the closing member due to the pressure difference. Can be moved to unlock the vent.

  According to the door operation device of the present invention, it is possible to easily and appropriately provide a function for correcting a situation in which the door is difficult to open due to a pressure difference caused by ventilation by simply combining the door operation device with the door. be able to.

  A typical embodiment of the present invention will be described below with reference to FIGS. 1 to 7 are a first example of the door operating device H, FIGS. 8 and 9 are a second example of the door operating device H, and FIGS. 10 to 14 are a third example of the door operating device H. Respectively.

  A door operating device H according to this embodiment is attached to a door D and is provided with a door operating body 1 such as a door handle or a door knob. That is, the door operating device H includes a device main body 2 that is attached to the door D using the attachment portion Dc of the door operating body 1 formed on the free end Db side opposite to the hinge side Da of the door D. The door operation body 1 provided in the apparatus main body 2 is provided.

  The mounting portion Dc is formed as a space that continues to the inside of the door D with the opening Dd provided at the free end Db of the door D. The apparatus main body 2 has a case shape that can be accommodated in the mounting portion Dc. One wide surface 20 of the apparatus main body 2 is positioned inward of one surface of the door D so as to be parallel to this one surface, and the wide other surface 20 of the apparatus main body 2 is disposed inward of the other surface of the door D. In addition, one of the side end portions 21 in the apparatus main body 2 closes the opening of the attachment portion Dc and becomes a part of the free end Db portion of the door D. As shown in FIG. 3, the door operation body 1 is typically provided on one surface side and the other surface side of the door D through a through hole of the support portion 10 of the door operation body 1 communicating with the attachment portion Dc. A latch bolt 22 for a strike provided on a door frame (not shown) protrudes from one of the side end portions 21 of the apparatus body 2, and when the door operating body 1 is operated in the direction to open the door D, the latch bolt 22 is attached to the apparatus body 2. Then, the door D is allowed to open.

  The door operating device H according to this embodiment normally maintains the airtightness of the door D, and when opening the door D, the air pressure is applied to the space Sa on one side and the space Sb on the other side across the door D. Even if there is a difference, the operation of the door operation body 1 is used as an opportunity to rapidly reduce the pressure difference so that the door D can be opened with a small force.

  Each of the door operation devices H according to this embodiment includes a ventilation portion 23 that communicates the space Sa on one side and the space Sb on the other side with the door D sandwiched between the device body 2. The door D is formed with a vent hole Df communicating with the vent portion 23. At the same time, the device main body 2 incorporates a closing member 24 of the ventilation portion 23 that is moved to a position to release the closing of the ventilation portion 23 in conjunction with an operation of opening the door D of the door operation body 1. ing.

  Thereby, in the door operation device H according to this embodiment, the air tightness of the door D can be ensured by normally closing the ventilation portion 23 by the closing member 24. On the other hand, when the door D is opened, even if there is a pressure difference between the space Sa on one side and the space Sb on the other side where the door D is opened by closing the ventilation portion 23, the operation of the door operation body 1 is performed. The door D can be opened with a small force by rapidly reducing the pressure difference. In particular, the door operating device H has an advantage that the above functions can be easily given to the doors D by being provided to the existing doors D or the existing doors D.

  As a case where there is a pressure difference between the space Sa on one side and the space Sb on the other side across the door D, typically, the inside of the building is at a lower pressure than the outside due to the third type ventilation. Can be given. Alternatively, there is a case where one room inside the building is lower in pressure than the space adjacent to this one room which is partitioned from this one room by the door D due to the third type ventilation.

  Further, in the door operation device H according to the first and second examples, a plurality of the ventilation portions 23 are formed in the vertical direction of the device main body 2. Further, in the door operating device H according to the third example, the ventilation portion 23 is formed continuously in the vertical direction of the device main body 2. Thereby, in the door operation device H according to this embodiment, the ventilation portion 23 can be rationally formed in a manner in which the ventilation flow rate is increased as much as possible in the space of the door operation device H combined with the door D. When there is a difference in the atmospheric pressure triggered by the operation of the door operation body 1, this difference is rapidly reduced.

  Further, in any of the door operation devices H according to the first to third examples, the entrance of the ventilation portion 23 opens a ventilation gap Dh between the outer surface Dg of the door D and the door D is provided in the door D. The outer cover is covered with the blindfold 3 so that the ventilation portion 23 does not affect the appearance of the door D while ensuring ventilation through the ventilation gap Dh.

(First example)
In the door operating device H according to the first example, the device main body 2 includes a side end portion 21 from which the latch bolt 22 protrudes and a side end portion 21 positioned on the center side of the door D facing the side end portion 21. , A rotating member denoted by reference numeral 251 is built in the upper center, and a closing member 24 is built in between the rotating member 251 and the side end portion 21 ′ located on the center side of the door D. ing. The ventilation portion 23 is formed at three locations with a space in the vertical direction between the rotating member 251 and the side end portion 21 ′ located on the center side of the door D. The ventilation portion 23 is formed by forming a through hole 23a in each of the plate body forming the one surface 20 of the apparatus main body 2 and the plate body forming the other surface 20 of the apparatus main body 2. Each through-hole 23a has a rectangular shape with a long side extending in the left-right direction, and is directly behind each through-hole 23a on the one surface 20 side of the apparatus body 2, and the corresponding through-hole 23a on the other surface 20 side. Is supposed to be located.

  The rotation member 251 is supported by the apparatus body 2 so that the rotation center axis is arranged in the thickness direction of the door D. The rotating member 251 includes a central portion 251a, an upper arm 251b projecting upward from the central portion 251a, a lower arm 251c projecting downward from the central portion 251a, and toward the closing member 24 from the central portion 251a. And a linkage arm 251d that protrudes. A square hole is formed in the central portion 251a of the rotating member 251, and the fixed shaft of the lever handle 1 'indicated by reference numeral 11 in the drawing is passed through the square hole so that the one surface 20 side and the other surface 20 of the apparatus main body 2 are provided. A lever handle 1 ′ as a door operation body 1 is provided on each side. The upper arm 251b of the rotating member 251 is linked to the latch bolt 22 positioned at the protruding position by the bias of the latch bolt spring indicated by reference numeral 252 in the figure, and is normally positioned vertically, and the lower arm 251c is shown in the figure. The lever handle 1 ′ is positioned at the reference position by the rotating member 251 that is biased toward the closing member 24 side by the auxiliary spring indicated by the intermediate code 253 and is normally positioned in the vertical direction. (FIG. 4) When the lever handle 1 ′ at the reference position is operated, the rotating member 251 is rotated against the urging force of the two springs 252 and 253, the latch bolt 22 is retracted, and the ventilation portion 23. The closing member 24, which has been closed, is moved downward by the movement of the linkage arm 251d to release the closing. (FIG. 6) In this first example, when there is a pressure difference between the space Sa on one side of the door D and the space Sb on the other side, the direction of the force applied to the closing member 24 due to the pressure difference. Since the closing member 24 is moved by the operation of the lever handle 1 ′ in the lower direction perpendicular to the orthogonal direction, the closing member 24 is relatively moved in a direction opposite to the direction in which the force is applied. The closing member 24 can be smoothly moved to unblock the ventilation portion 23. That is, in this example, the closing member 24 moves in a direction crossing the ventilation direction x of the ventilation portion 23 in conjunction with the operation of opening the door D of the door operation body 1 to release the closure of the ventilation portion 23. It has become.

  The closing member 24 is accommodated in the apparatus main body 2 so as to slide in the vertical direction. The closing member 24 has a plate shape with a thickness that fits tightly between the inner surface of the plate body constituting the one surface 20 of the apparatus main body 2 and the inner surface of the plate body constituting the other surface 20. The closing member 24 has through-holes 24a that do not communicate with the through-holes 23a that form the ventilation portions 23 formed in the apparatus main body 2 at the position before the closing member 24 is lowered and communicate at the end-down position. Is formed. The linking arm 251 d of the rotating member 251 is linked to the closing member 24 by inserting the arm end into a connecting recess 24 b formed on the side of the closing member 24 on the rotating member 251 side. Yes. When the lever handle 1 ′ is at the reference position, the closing member 24 is positioned at the position before being lowered by the linkage arm 251d, and the through hole 23a on the one surface 20 side and the through hole 23a on the other surface 20 side A portion where the through hole 24 a of the closing member 24 is not formed enters between the two, and the ventilation portion 23 is closed by the closing member 24. (FIG. 4) When the lever handle 1 'at the reference position is operated, the arm end of the linkage arm 251d is moved downward by the rotation of the rotation member 251, thereby moving the closing member 24 to the lowering end position. The through hole 24a of the closing member 24 is positioned between the through hole 23a on the one surface 20 side of the main body 2 and the through hole 23a on the other surface 20 side so that the ventilation portion 23 is unclosed. (Fig. 6)

  In this first example, the blindfold 3 is configured as a substantially rectangular plate-like body that is long in the vertical direction. The length of the blindfold 3 is longer than the vertical dimension of the apparatus main body 2. The device D is attached to the door D with a location located above the upper end portion of the apparatus main body 2 and a location located below the lower end portion. A plurality of spacer portions 30 for forming a ventilation gap Dh between the outer surface Dg of the door D and the surface of the blindfold 3 are provided on the side facing the outer surface Dg of the door D in the blindfold 3. .

(Second example)
The door operation device H according to the second example is different from the door operation device H of the first example in that it is configured to be able to release the linkage between the rotation member 251 and the closing member 24. In other respects, the door operation device H according to the second example is substantially the same as the door operation device according to the first example, and thus the description thereof is omitted. In this second example, the closing member 24 is composed of a main part 24c in which a through hole 24a is formed, and a sub-part 24d combined so as to be slidable in the left-right direction with respect to the main part 24c. The sub-part 24d is formed with a link recess 24b for the arm end of the link arm 251d of the rotating member 251. Thus, in this second example, the sub-part is moved from the linkage state in which the arm end of the linkage arm 251d is inserted into the linkage recess 24b of the sub-part 24d in a direction in which the arm end is pulled out from the linkage recess 24b. By sliding the slider 24d, the closing member 24 can be prevented from being moved even if the lever handle 1 'is operated. (Fig. 9)

  In this second example, the sub-part 24d is guided by the split groove 261 formed in the plate body constituting the one surface 20 side or the other surface 20 side of the apparatus body 2, and the split groove 261 and A shaft portion 24e that protrudes outward at an outer end through a through hole (not shown) formed in the door D communicating therewith is provided. The split groove 261 includes a first vertical groove portion 261a, a second vertical groove portion 261b, and a horizontal groove portion 261c extending between the upper end of the first vertical groove portion 261a and the upper end of the second vertical groove portion 261b. The first vertical groove portion 261 a is on the side close to the rotating member 251. When an operation of moving the shaft portion 24e into the second longitudinal groove portion 261b through the lateral groove portion 261c by picking the outer end of the shaft portion 24e from the state where the shaft portion 24e is at the upper end of the first vertical groove portion 261a, the sub-parts are performed. 24d is moved away from the rotating member 251, and the arm end of the connecting arm 251d comes out of the connecting recess 24b of the rotating member 251, so that the link between the lever handle 1 'and the closing member 24 is released. In the illustrated example, when the shaft portion 24e is further moved from this state toward the lower end of the second vertical groove portion 261b, the main part 24c is moved downward together with the subparts 24d so that the closing member 24 reaches the lowering end position. It has become. Accordingly, in the illustrated example, it is possible to create a state where the closed state of the ventilation portion 23 is always released regardless of the operation of the lever handle 1 ′. (Fig. 9)

(Third example)
In the door operating device H according to the third example, the device main body 2 includes a slide body 24f as a closing member 24 incorporated in the device main body 2 so as to be slidable in the left-right direction of the door D, and a handle as the door operating body 1. And an interlocking bar 272 that is slidably moved in the thickness direction of the door D by the operation of the bar 1 ″.

  The handle bar 1 ″ is provided so as to extend between a pair of upper and lower bearing portions 273 and 273 provided on the one surface 20 side and the other surface 20 side of the apparatus main body 2. The handle bar 1 ″ is long in the left-right direction. The shaft body 12 has a horizontal cross section and has a shaft portion 12 with an axial line arranged in the vertical direction on the bearing portion 273 at one end side thereof so as to be rotatable. The other end of the handle bar 1 ″ is directed toward the center of the door D.

  The interlocking bar 272 extends both ends of the bar to the outside of the apparatus main body 2 through the inside of the apparatus main body 2 and is rotatably attached to one end of the handle bar 1 ″ on the one surface 20 side of the apparatus main body 2. In addition, the other end of the bar is rotatably assembled between both ends of the handle bar 1 "on the other surface side of the apparatus body 2, and the door D can be slid in the thickness direction even if any handle bar 1" is operated. It has come to occur.

  The ventilation portion 23 is formed at a location near the center side of the door D in the apparatus main body 2. The ventilation part 23 is formed in the apparatus main body 2 so as to be long in the vertical direction. The entrance of the ventilation unit 23 on the one surface 20 side (lower side in FIG. 11) of the apparatus main body 2 is located farther from the free end Db side of the door D than the entrance on the other surface side of the apparatus main body 2. Is the first flow path 23d extending from the entrance on the one surface 20 side of the apparatus body 2 to the position in the middle of the thickness direction of the door D, and the thickness direction of the door D from the entrance on the other surface 20 side of the apparatus body 2 The second flow path 23b extending to a substantially middle position is connected by a communication flow path 23e that is long in the vertical direction at a position substantially in the middle of the thickness direction. Accordingly, in this example, since the ventilation portion 23 does not continue straight along the thickness direction of the door D, a tool for unlocking the door D is inserted into the room using the ventilation portion 23. Is getting harder. The entrance of the ventilation portion 23 is also covered with a plate-shaped blindfold 3 that is long in the vertical direction with the ventilation gap Dh. Reference numeral 30 in the figure denotes a spacer portion that creates this ventilation gap Dh.

  The slide body 24f has an outer end portion 24g provided with the latch bolt 22 and an inner end portion 24h provided with a valve body 24i with respect to the communication flow path 23e of the ventilation portion 23. The inner end portion 24h of the slide body 24f enters the ventilation portion 23 through a through hole 23c formed in the wall portion located on the free end Db side of the door D forming the second flow path 23b. A valve body 24i that is long in the vertical direction is formed at the end of the inner end 24h of the slide body 24f so as to be seated on the inner wall of the communication flow path 23e from the first flow path 23d side and close the ventilation part 23. .

  Reference numeral 274 in the figure denotes a latch bolt spring that constantly urges the latch bolt 22 in a direction in which the latch bolt 22 protrudes from the outer end 24g of the slide body 24f. On the other hand, the slide body 24f is formed in the apparatus main body 2 with a spring pressing portion 275 facing the free end side Db of the door D, and formed on the outer end side of the slide body 24f and facing the center side of the door D. The valve body 24i is normally positioned at a position where the valve body 24i is seated on the inner wall of the communication flow path 23e by a compression coil spring 276 interposed between the spring holding portion 24j and the spring holding portion 24j. (Fig. 11)

  Inside the apparatus main body 2, a first gear portion 277b that meshes with a rack 24k formed at an intermediate portion of the slide body 24f, and a second gear portion 277a that meshes with a rack 272a formed at an intermediate portion of the interlocking bar 272. A pinion 277 provided integrally on the upper and lower sides is arranged with the rotation axis along the vertical direction. In the third example, the handle bar 1 ″ is positioned at the reference position via the slide body 24f and the interlocking bar 272 by the bias of the compression coil spring 276.

  In this third example, when the handle bar 1 ″ at the reference position is pulled on one side of the door D (the lower side in FIG. 11), the slide body 24f is moved to the center side of the door D via the pinion 277. As a result of the sliding movement, the valve body 24i is separated from the inner wall of the communication flow path 23e, so that the vent 23 is unclosed.In this example, the other surface 20 of the door D (FIG. 11). On the upper side), when the handle bar 1 ″ at the reference position is pushed, the ventilation portion 23 is unclosed. For example, when the door opening device H according to the third example is provided to the front door D that is opened outwardly, the ventilation portion 23 is not closed when the handle bar 1 ″ positioned on the outdoor side of the door D is pulled. Let it be.

  As shown in FIG. 13, if the first gear portion 277b of the pinion 277 is configured to have a larger diameter than the second gear portion 277a, the slide body 24f is moved more greatly than the moving amount of the interlocking bar 272. The latch bolt 22 can be easily removed from the strike.

  Further, as shown in FIG. 14, instead of the pinion 277, the bent portion 271a is rotatably supported by the apparatus main body 2, and one end 271b sandwiching the bent portion 271a is rotatable to the slide body 24f. It is also possible to link the slide body 24f and the handle bar 1 ″ by using the link body 271 that is assembled to the other end 271c to the interlocking bar 272 so as to be rotatable.
