Description

The present invention relates to a door operating device for releasing a latch bolt when opening a door.

The latch bolt provided on the door end side of the door that opens by rotating is urged by a spring in the protruding direction (Patent Documents 1, 2, etc.). In the closed position of the door, the latch bolt protrudes and engages with the latch receiver of the door frame to fix the door in the closed position. When opening a door in the closed position, the door can be opened by operating a handle such as a lever handle or push-pull handle to temporarily retract the latch bolt against the spring. When closing the door in the open position, it is not necessary to operate the handle because the latch bolt retracts by itself against the spring due to the shape of the latch bolt.

Door handles can be a transmission route for pathogens such as viruses and bacteria. Frequent disinfection of the door handle or the hand that touches it is cumbersome, and it is preferable that the door handle is not touched by the fingers to prevent infection.

Patent Documents 1 to 3 present a specially shaped handle or an attachment attached to an existing handle in order to open and close the door using a portion above the wrist without using fingers.

Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples. In the drawings, the same or similar components in each embodiment are designated by essentially the same reference numerals. In addition, the same or similar components already described in another embodiment may be omitted.

The door to which the present invention is applied is a single door that has one plate-shaped door body and rotates around a vertical rotation shaft at one end to open and close. Regarding the width direction of the door body, the rotation axis is referred to as "door tail side", and the side opposite to the rotation axis is referred to as "door tip side".

(1) First Embodiment With reference to FIGS. 1 to 7, a first embodiment of the door operating device 10 of the present invention will be described. 1 (a) is a schematic perspective view of the door 1 to which the door operating device 10 of the first embodiment is attached as viewed from one door surface 1a, and FIG. 1 (b) is a schematic perspective view seen from the opposite door surface 1b. It is a schematic perspective view. The door 1 of the first embodiment is a door that can be opened only on one side of both door surfaces 1a and 1b, in this case only on the door surface 1b side. For example, the door surface 1a faces the corridor side, and the door surface 1b faces the indoor side. FIG. 1 shows a state in which the door 1 is in the closed position.

The door operating device 10 is attached to the door body of the door 1. The door operating device 10 of the present embodiment includes a component incorporated in the door body and a component attached to the first and second door surfaces 1a and 1b facing each other in opposite directions. As one of the components incorporated in the door body, there is a case 4 of a substantially rectangular parallelepiped embedded in the door end side of the door 1. This case 4 is similar to a key case containing a latch bolt and a dead bolt in a general door.

In the example of FIG. 1, only the latch bolt 3 is provided in the case 4, and the dead bolt is not provided. In the present invention, the deadbolt is not essential but an arbitrary element. The latch bolt 3 is elastically urged so as to protrude from the side surface of the case 4 on the door end side. At the closed position of the door 1, the latch bolt 3 protrudes from the case 4 and enters the opposing latch receiving hole (not shown). In this state, the door 1 is prevented from opening toward the door surface 1b.

The door 1 has one door through hole that penetrates perpendicularly to the door surface. Here, the hole penetrating the member constituting the first door surface 1a is referred to as "door through hole 1c", and the hole penetrating the member constituting the second door surface 1b is referred to as "door through hole 1d". ing. The door through hole 1c and the door through hole 1d completely overlap each other when viewed from a direction perpendicular to the door surface.

It is preferable that the door operating device 10 according to the present embodiment is installed by removing the handles and key cases provided on the existing doors and using their mounting holes. In that case, the case 4 is preferably fitted into the mounting hole of the key case. Further, the mounting holes of the existing handles are used as they are as the door through holes 1c and 1d. However, the door operating device 10 can also be applied to a new door.

In the first embodiment, since the case 4 overlaps the positions of the door through holes 1c and 1d when viewed from the direction perpendicular to the door surface, the case through holes 4a and 4b are also formed on the side wall of the case 4. ing. The case through holes 4a and 4b are located at the same positions as the door through holes 1c and 1d, and are preferably the same size or larger than the door through holes 1c and 1d.

The door operating device 10 has a first support frame 11 attached to the first door surface 1a and a second support frame 21 attached to the second door surface 1b. It is preferable that the support frame 11 and the support frame 21 are attached in opposite directions with the door 1 interposed therebetween so that they have the same contour shape and overlap with each other when viewed from a direction perpendicular to the door surface. The method of attaching the support frames 11 and 21 to the door surfaces 1a and 1b is arbitrary and will not be described in detail, but for example, screwing or bonding can be used.

In the first support frame 11, a first rotation shaft 12 provided vertically along the wall on the door tail side and a first rotation shaft 12 rotatably mounted around the rotation shaft 12 An operation plate 13 is arranged. The "axis" here means a member including a geometric axis. On the other hand, also in the second support frame 21, a second rotation shaft 22 provided in the vertical direction along the wall on the door tail side and a second rotation shaft 22 rotatably attached around the rotation shaft 22. The operation plate 23 of 2 is arranged. The rotating shafts 12 and 22 are supported by the support frames 11 and 21, respectively, and specifically, are configured by, for example, one or a plurality of hinges.

Since the main function of the support frames 11 and 21 is to support the rotation shafts 12 and 22 (indirectly supporting the operation plates 13 and 23), the support frames 11 and 21 are the operation plates 13 and 23. It is not essential to surround the entire circumference. Therefore, the support frames 11 and 21 can have any shape as long as the operation plates 13 and 23 are rotatably arranged. In the example of FIG. 1, edge portions 11e and 21e having an appropriate width surrounding the openings of the support frames 11 and 21 are formed. These edges 11e and 21e may be provided on the entire circumference or a part of the opening as needed, and may be different between the support frame 11 and the support frame 21 as shown in the figure.

As an example, the operation plates 13 and 23 have a rectangular contour shape so as to substantially correspond to the support frames 11 and 21 having a rectangular contour shape when viewed from a direction perpendicular to the door surface. The operation plates 13 and 23 have a thickness thinner than the depth length of the support frames 11 and 21. The rotation shaft 12 and the operation plate 13 on the door surface 1a side are arranged on the front side of the support frame 11, while the rotation shaft 22 and the operation plate 23 on the door surface 1b side are arranged on the back side of the support frame 21. Will be done. The wide surfaces of the operation plates 13 and 23 are arranged parallel to the door surfaces 1a and 1b in the non-operation position of FIG. The contour shapes and sizes of the operation plates 13 and 23 are not limited to the illustrated examples. The contour shapes of the operation plates 13 and 23, the length in the vertical direction, the width in the horizontal direction, and the positions of the upper, lower, left, and right edges can be freely set in a wide range in consideration of ease of operation.

Further, in the present embodiment, the auxiliary operation plate 24 extending substantially perpendicular to this surface is arranged from the surface of the operation plate 23 on the door surface 1b side facing the door 1 to open. The auxiliary operation plate 24 can rotate around the rotation shaft 22 integrally with the operation plate 23. The auxiliary operation plate 24 has a rectangular contour shape in the illustrated example. The auxiliary operation plate 24 does not have to be strictly perpendicular to the operation plate 23, and may be inclined by, for example, −10 ° to + 10 ° with respect to the vertical position. One wide surface of the auxiliary operation plate 24 faces the door end side, and the other wide surface faces the door end side. The base end of the auxiliary operation plate 24 is preferably arranged in the vicinity of the rotation shaft 22 in the operation plate 23.

The length of the auxiliary operation plate 24 in the vertical direction is preferably about the same as that of the operation plate 23. Since the auxiliary operation plate 24 protrudes from the opening of the support frame 21, it is preferable to set the width of the auxiliary operation plate 24 in consideration of not colliding with a person or an object.

2 (a) and 2 (b) are schematic perspective views corresponding to FIGS. 1 (a) and 1 (b) in a state where the door operating device 10 is operated to release the latch bolt 3. The arrow r1 in FIG. 2A indicates an operation in which the user on the door surface 1a side pushes the operation plate 13. The arrow r2 in FIG. 2B indicates an operation in which the user on the door surface 1b side pushes the auxiliary operation plate 24.

By operating the operation plate 13 or the auxiliary operation plate 24 in this way, the operation plates 13 and 23 rotate toward the door surface 1b around the rotation shafts 12 and 22, respectively, and the operation plates 13 and 23 become the operation plates 13 and 23. It is inclined with respect to the door surfaces 1a and 1b. The operation plate 13 and the auxiliary operation plate 24 to be operated have a large operation surface as compared with a general door handle. Therefore, the user can operate the operation plate 13 or the auxiliary operation plate 24 using a body part other than the fingers, for example, an elbow, an arm, a shoulder, a waist, a leg, a knee, a foot, or the like, which is convenient. can. Of course, it is also possible to operate using fingers. The operation plate 13 arranged in the support frame 11 can only be pushed. On the other hand, the auxiliary operation plate 24 arranged in the support frame 21 can be operated to pull the edge of the auxiliary operation plate 24 from the door tail side, for example, in addition to the operation of pushing the surface on the door end side as shown in the figure. ..

Although the details will be described later, the door operation device 10 has a conversion unit that converts the rotation of the operation plates 13 and 23 into the retracting operation of the latch bolt 3. Therefore, when the operation plates 13 and 23 are rotated by the operation of the user, the latch bolt 3 is retracted against the elastic force and released. As a result, the user can open the door 1 as shown by the arrow R1. That is, the user can open the door 1 without using fingers.

FIG. 3 is an enlarged and schematic view of the I-I cross section of FIG. This cross section is a vertical cross section substantially corresponding to the positions of the door through holes 1c and 1d and the case through holes 4a and 4b. The door operating device 10 of the present invention has a rod-shaped connecting rod 5 having a longitudinal axis extending in the horizontal direction. The connecting rod 5 connects the first operation plate 13 and the second operation plate 23 through the door through holes 1c and 1d. In the illustrated example, the connecting rod 5 also passes through the case through holes 4a and 4b. As will be described later, since the connecting rod 5 is moved horizontally in the door through holes 1c and 1d along the longitudinal axis thereof, the connecting rod 5 does not collide with the peripheral edges of the door through holes 1c and 1d during the movement. As described above, the size of the cross section of the connecting rod 5 is appropriately set. The cross-sectional shape of the connecting rod 5 may be circular or polygonal.

One end 5a of the connecting rod 5 is connected to a connecting portion 13a formed on the back surface of the operation plate 13. Here, one end 5a of the connecting rod 5 is rotatably connected to the operation plate 13 in a horizontal plane. Further, the other end 5b of the connecting rod 5 is connected to the connecting portion 23a formed on the back surface of the operation plate 23. Here, the other end 5b of the connecting rod 5 is rotatably connected to the operation plate 23 in a horizontal plane. The connecting rod 5 is one of the components of the conversion unit.

An example of the mechanism of the conversion unit will be described with reference to FIGS. 4 and 5. 4 (a) schematically shows an example of the II-II cross section of FIG. 1 (b), and FIG. 4 (b) schematically shows the III-III cross section of FIG. 1 (a).

At the latch position shown in FIG. 4A, the latch bolt 3 is urged by the spring 6 and protrudes from the side surface of the case 4 on the door end side. An operation rod 3a integrally fixed to the back surface of the latch bolt 3 penetrates the coiled spring 6 and extends horizontally toward the side surface of the case 4 on the door tail side. The operation rod 3a penetrates the partition wall 4c in the case 4, and a first connecting pin 7a is provided at the end thereof. One end of the spring 6 is supported by the back surface of the latch bolt 3, and the other end is supported by the partition wall 4c.

An operating point 5c is set at a predetermined intermediate position along the longitudinal axis of the connecting rod 5, and a second connecting pin 7b is provided at the operating point 5c.

At appropriate positions between the first connecting pin 7a and the second connecting pin 7b, a guide pin 7c fixed to the case 4 and extending in the vertical direction is arranged. Further, one end of the wire 7 is connected to the first connecting pin 7a, and the other end is connected to the second connecting pin 7b. The length and slack of the wire 7 are set as necessary.

In the latch position, the operation plates 13 and 23 are positioned parallel to the door surfaces 1a and 1b, and the connecting rod 5 is in the initial position. The operation rod 3a integrated with the latch bolt 3 is located at the position closest to the door end side.

As shown in FIG. 4A (see also FIG. 3), it is preferable to form a rounded rib 24a projecting toward the door end along the edge of the auxiliary operation plate 24. When the user hangs an elbow, a foot, or the like on the rib 24a, the operation of the auxiliary operation plate 24 becomes easy.

5 (a) and 5 (b) are views corresponding to FIGS. 4 (a) and 4 (b) when the latch bolt 3 is in the release position. At the latch release position shown in FIG. 5A, the latch bolt 3 is retracted into the case 4 against the spring 6. This latch release position is realized by, for example, an operation of pushing the operation plate 13 as shown by the arrow r1 or an operation of pushing the auxiliary operation plate 24 as shown by the arrow r2. Regardless of which operation is performed, the operation plates 13 and 23 rotate at the same time around the rotation shafts 12 and 22, respectively. The interlocking of the operation plate 13 and the operation plate 23 is realized by the connecting rod 5. The connecting rod 5 itself also moves horizontally in the door through holes 1c and 1d. The rotation range of the operation plates 13 and 23 is limited to the inside of the support frames 11 and 21. For this reason, it is preferred that the edges 11e, 21e or the door surfaces 1a, 1b of the support frames 11 and 21 act as stoppers (as well as for other similar embodiments).

When the operating point 5c (that is, the connecting pin 7b) on the connecting rod 5 moves, the wire 7 engages with the guide pin 7c to apply tension and is further pulled toward the connecting pin 7b. As a result, the wire 7 pulls the operation rod 3a toward the door end, so that the latch bolt 3 retracts against the spring 6. In this state, if the user further pushes the operation plate 13 or the auxiliary operation plate 24, the door rotates and opens. At this time, with respect to the auxiliary operation plate 24, the body part may be hooked on the rib 24a and pulled.

The door 1 in the open state can be closed by pushing an arbitrary place on the door surface 1b. It is preferable that the door 1 has a mechanism that automatically returns to the closed position when left in the open state. Such a mechanism is well known, but not within the scope of the present invention.

When the user separates the body part from the door operating device 10, the door operating device 10 returns to the latch position of FIG. At this time, it is preferable that the latch bolt 3 (operation rod 3a) returns to the initial position due to the restoring force of the spring 6, and at the same time, the connecting rod 5 and the operation plates 13 and 23 also return to the initial positions. Although not shown, another spring may be provided to elastically urge the connecting rod 5 or the operating plates 13 and 23 to the initial position in order to assist the restoring force of the spring 6 (also in other embodiments). same).

Another example of the mechanism of the conversion unit will be described with reference to FIGS. 6 and 7. FIG. 6 (a) schematically shows another example of the II-II cross section of FIG. 1 (b), and FIG. 6 (b) schematically shows the IV-IV cross section of FIG. 1 (a).

At the latch position shown in FIG. 6A, the latch bolt 3 is urged by the spring 6 and protrudes from the side surface of the case 4 on the door end side. An operation rod 3a integrally fixed to the back surface of the latch bolt 3 penetrates the coiled spring 6 and extends horizontally toward the side surface of the case 4 on the door tail side. The operation rod 3a penetrates the partition wall 4c in the case 4. One end of the spring 6 is supported by the back surface of the latch bolt 3, and the other end is supported by the partition wall 4c. A rack 8a is formed on the side surface of the operation rod 3a within a predetermined range from the tip thereof. Further, in the case 4, a pinion 8b is arranged at a position capable of meshing with the rack 8a. Another pinion 8c is provided coaxially with the pinion 8b.

A rack 8d is formed on the side surface of the connecting rod 5 in a predetermined range along the longitudinal axis thereof. As shown in FIG. 6B, the rack 8d is arranged so as to be toothable with the pinion 8c at a height different from that of the pinion 8b.

As shown in FIG. 6A, in the latch position, the operation plates 13 and 23 are located parallel to the door surfaces 1a and 2b, and the connecting rod 5 is in the initial position. The operation rod 3a integrated with the latch bolt 3 is located at the position closest to the door end side.

7 (a) and 7 (b) are views corresponding to FIGS. 6 (a) and 6 (b) when the latch bolt 3 is in the release position. At the latch release position shown in FIG. 7A, the latch bolt 3 is retracted into the case 4 against the spring 6. This latch release position is realized by, for example, an operation of pushing the operation plate 13 as shown by the arrow r1 or an operation of pushing or pulling the auxiliary operation plate 24 as shown by the arrow r2. Regardless of which operation is performed, the operation plates 13 and 23 rotate at the same time around the rotation shafts 12 and 22, respectively. The interlocking of the operation plate 13 and the operation plate 23 is realized by the connecting rod 5. The connecting rod 5 itself also moves horizontally in the door through holes 1c and 1d. When the connecting rod 5 moves, the rack 8d meshes with the pinion 8c and rotates it. As a result, the pinion 8b rotates, and the rack 8a of the operating rod 3a that meshes with the pinion 8b moves linearly to the door tail side. As a result, the latch bolt 3 retracts against the spring 6.

The mechanism of the conversion unit shown in FIGS. 4 and 5 or 6 and 7, respectively, is an example, and the rotation of the operation plates 13 and 23 is caused by the movement of the connecting rod 5 to the latch bolt 3. The mechanism for converting to the backward motion is not limited to these. The conversion unit can be variously configured by appropriately combining a cam, a link, a spring, a gear, a rack, and / or an electric drive device (the same applies to other embodiments).

Further, in the first embodiment, the rotating shafts 12 and 22 are vertical axes, but instead, the rotating shafts 12 and 22 can be used as horizontal axes. In that case, for example, the rotating shafts 12 and 22 can be attached along the upper end or the lower end of the support frames 11 and 21, respectively. Also in this case, the movement of the connecting rod 5 caused by the rotation of the operation plates 13 and 23 is substantially the same as that of the first embodiment, and the movement of the connecting rod 5 is transmitted to the operation rod 3a via the conversion unit.

(2) Second Embodiment FIG. 8 shows a second embodiment of the door operating device 10 of the present invention. Since the second embodiment is a modification of the first embodiment, only the points different from the first embodiment will be described. 8 (a) schematically shows a cross section corresponding to the II-II cross section of FIG. 1 (b), and FIG. 8 (b) schematically shows the VV cross section of FIG. 1 (a).

In the second embodiment, the door through holes 1c and 1d do not overlap with the case 4 in the direction perpendicular to the door surface, and are substantially adjacent to the outside of the side wall 4d on the door tail side of the case 4. 1c and 1d are located. In this case, it is not necessary to provide a through hole in the case 4. Instead, an opening 4e is provided on the side wall 4d on the door tail side of the case 4. Through this opening 4e, the movement of the connecting rod 5 is transmitted to the operating rod 3a via the wire 7. In addition, although the conversion unit illustrated in FIG. 4 is shown in FIG. 8, the conversion unit shown in FIG. 6 can be used instead, and another conversion unit can also be used. In the illustrated example, the door body is hollow, but when the door body is solid, one through hole is formed over the entire area from the door surface 1a to the door surface 1b.

(3) Third Embodiment FIG. 9 shows a third embodiment of the door operating device 10 of the present invention. Although the appearance of the entire door is omitted from the third embodiment, it is similar to the appearance of the entire door of the first embodiment shown in FIG. However, in the third embodiment, the door 1 is a door that can be opened on either side of both door surfaces 1a and 1b.

9 (a) is a cross-sectional view of the latch state of the third embodiment of the door operating device 10, and corresponds to FIG. 4 (a) of the first embodiment. FIG. 9B is a cross-sectional view of the latch released state.

The door operating device 10 of the third embodiment has a substantially rectangular parallelepiped case 4 embedded in the door end side of the door 1, as in the first embodiment. In a third embodiment, the latch bolt 3 has a well-known shape corresponding to a door that opens to either side of the first and second door surfaces 1a and 1b (see, for example, Patent Documents 4 and 5). In the closed position of the door 1, the latch bolt 3 protrudes from the side surface of the case 4 on the door end side and enters the facing latch receiving hole (not shown). As a result, the door 1 is prevented from opening to either side.

In the illustrated example, as in the second embodiment, the door through holes 1c and 1d are located substantially adjacent to the outside of the side wall on the door tail side of the case 4 in the direction perpendicular to the door surface. Instead of this, the same case 4 as in the first embodiment can be adopted.

Similar to the first embodiment, the third embodiment also has the support frames 11 and 21 attached to the door surfaces 1a and 1b, and the operation plates 13 arranged in the support frames 11 and 21 respectively. 23. The operation plates 13 and 23 each have a contour shape that substantially fits into the internal space of the support frames 11 and 21, and have a thickness thinner than the depth length of the support frames 11 and 21, respectively. In this case, the operation plate 23 is not provided with the auxiliary operation plate. The rotation shafts 12 and 22 of the two operation plates 13 and 23 extend in the vertical direction along the wall on the door tail side of the support frames 11 and 21. In the third embodiment, the rotation shafts 12 and 22 are located at the center of the depth lengths of the support frames 11 and 21. The operation plates 13 and 23 are connected by a connecting rod 5 that passes through the door through holes 1c and 1d. Therefore, the operation plates 13 and 23 are interlocked with each other via the connecting rod 5.

In the third embodiment, the user pushes the operation plate 13 from the door surface 1a side or pushes the operation plate 23 from the door surface 1b side to rotate the operation plates 13 and 23. The rod 5 moves, the latch bolt 3 is released, and the door 1 can be opened. The door operating device 10 has a conversion unit that converts the movement of the connecting rod 5 due to the rotation of the operating plates 13 and 23 into the retracting operation of the latch bolt 3. Since the operation plates 13 and 23 have a larger operation surface than the conventional handle, the user can easily operate the operation plates 13 and 23 by using a body part other than the fingers.

At the latch position shown in FIG. 9A, the latch bolt 3 is urged by the spring 6 and protrudes from the side surface of the case 4 on the door end side. An operation rod 3a integrally fixed to the back surface of the latch bolt 3 penetrates the coiled spring 6 and extends horizontally toward the side surface of the case 4 on the door tail side. The operation rod 3a penetrates the partition wall 4c in the case 4, and a first connecting pin 7a is provided at the end thereof. One end of the spring 6 is supported by the back surface of the latch bolt 3, and the other end is supported by the partition wall 4c.

On the other hand, an operating point 5c is set at a predetermined intermediate position along the longitudinal axis of the connecting rod 5, and a second connecting pin 7b is provided at the operating point 5c.

At appropriate positions between the first connecting pin 7a and the second connecting pin 7b, a plurality of guide pins 7c fixed to the case 4 and extending in the vertical direction are arranged. Further, two wires 71 and 72 are provided with a required length and slack. One end of each of the wires 71 and 72 is connected to the first connecting pin 7a, and the other end is connected to the second connecting pin 7b. However, the wires 71 and the wires 72 have different routes defined by the plurality of guide pins 7c.

As shown in FIG. 9A, in the latch position, the operation plates 13 and 23 are located parallel to the door surfaces 1a and 1b, and the operation point 5c is located at the center of the door 1 in the thickness direction.

FIG. 9B shows a latch release state when the operation plate 13 is pushed from the door surface 1a side as shown by the arrow r1. By this operation, the operation plate 13 rotates around the rotation shaft 12 toward the door surface 1b (the operation plate 23 is also interlocked by the connecting rod 5). The rotation range of the operation plate 13 is defined by the support frame 11. As the operation plates 13 and 23 rotate, the operation point 5c of the connecting rod 5 and the second connecting pin 7b move toward the door surface 1b. As a result, the wire 71 engages with the guide pin 7c to apply tension, and pulls the operation rod 3a toward the door tail side. As a result, the latch bolt 3 retracts against the spring 6 and is released from the latch. Although not shown, when the operation plate 23 is pushed from the door surface 1b side, the operation plates 13, 23 and the conversion unit perform an operation symmetrical to that in FIG. 9B. Then, when the wire 72 pulls the operation rod 3a, the latch bolt 3 retracts and the latch is released.

(4) Fourth Embodiment FIG. 10 shows a fourth embodiment of the door operating device 10 of the present invention. Since the fourth embodiment is a modification of the third embodiment, only the points different from the third embodiment will be described. FIG. 10 is a cross-sectional view of the door operating device 10 in a latched state, and corresponds to FIG. 9A of the third embodiment. Since the latch release state is almost the same as in FIG. 9B, the illustration is omitted.

In the fourth embodiment, the auxiliary operation plates 14 and 24 are provided on each of the operation plates 13 and 23 in the third embodiment. Other than that, the configuration is the same as that of the third embodiment. The auxiliary operation plates 14 and 24 are the same as the auxiliary operation plates 24 in the first embodiment described above. In this case, the operation plates 13 and 23 can be rotated by pushing the auxiliary operation plates 14 and 24 toward the door tail side, respectively. The operation of the conversion unit and the operation of releasing the latch caused by the rotation of the operation plates 13 and 23 are the same as those in the third embodiment.

(5) Fifth Embodiment FIG. 11 shows a fifth embodiment of the door operating device 10 of the present invention. Although the appearance of the entire door is omitted from the fifth embodiment, it is similar to the appearance of the entire door of the first embodiment shown in FIG. The door 1 of the fifth embodiment is a door that can be opened only on one side of both door surfaces 1a and 1b, in this case only on the side of the door surface 1b. The fifth embodiment is different from the first embodiment in that the operation plate moves linearly.

FIG. 11A is a cross-sectional view of the latch state of the fifth embodiment of the door operating device 10, and corresponds to FIG. 4A of the first embodiment. FIG. 11B is a cross-sectional view of the latch released state.

The case 4 in the fifth embodiment shown in FIG. 11 is the same as that in the second embodiment, but the same case 4 as the first embodiment may be adopted. At the latch position shown in FIG. 11A, the latch bolt 3 protrudes from the side surface of the case 4 on the door end side and enters the facing latch receiving hole (not shown). As a result, the door 1 is prevented from opening toward the door surface 1b.

As shown in FIG. 11A, the door operating device 10 has support frames 11 and 21 attached to the door surfaces 1a and 1b, and the operation plates 13 arranged in the support frames 11 and 21 respectively. 23. The operation plates 13 and 23 each have a contour shape that substantially fits into the internal space of the support frames 11 and 21, and have a thickness thinner than the depth length of the support frames 11 and 21, respectively. The flat both sides of the operation plates 13 and 23 are parallel to the door surfaces 1a and 1b. The configuration of the connecting rod 5 and the conversion unit is the same as that of the first embodiment. That is, the operation plate 13 and the operation plate 23 are connected by a connecting rod 5 passing through the door through holes 1c and 1d.

At the latch position of FIG. 11A, the operation plate 13 in the support frame 11 on the door surface 1a side is arranged on the front side in the depth direction of the support frame 11. On the other hand, the operation plate 23 in the support frame 21 on the door surface 1b side is arranged on the back side in the depth direction of the support frame 21. Further, the operation plate 23 is provided with a support member 26 projecting in a direction perpendicular to the surface facing the opening side of the door 1, and an auxiliary operation plate 24 is provided at the tip of the support member 26.

The auxiliary operation plate 24 is attached so as to be substantially parallel to the operation plate 23. However, the auxiliary operation plate 24 does not have to be strictly parallel to the operation plate 23, and may be inclined by, for example, about −10 ° to + 10 ° with respect to the parallel position.

As an example, the support member 26 is a rod-shaped member protruding from substantially the center of the operation plate 23. The support member 26 further protrudes from the opening of the support frame 21 by a predetermined length. For the total length of the support member 26, the user puts a body part such as an elbow or a foot in the gap between the operation plate 23 and the auxiliary operation plate 24, hooks it on the auxiliary operation plate 24, and pulls the auxiliary operation plate 24. Set to the extent that it can be done. The size and contour shape of the auxiliary operation plate 24 are also appropriately set so as to be easy to operate. The contour shape of the auxiliary operation plate 24 is, for example, a circle. Further, it is preferable to provide a rounded rib 24a on the peripheral edge of the auxiliary operation plate 24 so that the user can easily catch the rib 24a.

The operation plates 13 and 23 are installed so as to be linearly movable in a direction perpendicular to the door surfaces 1a and 1b, respectively. For this purpose, for example, a pair of rails 15 and 25 are formed on the floor surface in the support frames 11 and 21 in a direction perpendicular to the door surface. For example, the rails 15 and 25 are ridges, and a groove fitted to the rails 15 and 25 is formed on the lower surfaces of the opposing operation plates 13 and 23. Although not shown, it is preferable to provide similar rail mechanisms on the ceiling surface in the support frames 11 and 21 and the upper surfaces of the operation plates 13 and 23. The mechanism for smoothly linearly moving the operation plates 13 and 23 within the support frames 11 and 21 is not limited to this.

As an example, the contour shapes of the support frames 11 and 21 and the operation plates 13 and 23 viewed from the direction perpendicular to the door surface are rectangular, but are not limited to rectangular. If the operation plates 13 and 23 can be linearly moved within the support frames 11 and 21, the contour shapes of the support frames 11 and 21 and the operation plates 13 and 23 may be circular or polygonal.

FIG. 11B shows a latch release state when the operation plate 13 is pushed from the door surface 1a side as shown by the arrow m1 or the auxiliary operation plate 24 is pulled from the door surface 1b side as shown by the arrow m2. ing. By this push or pull operation, the operation plates 13 and 23 linearly move to the opposite ends in the support frames 11 and 21, respectively. As a result, the connecting rod 5 also moves linearly in the door through holes 1c and 1d. The moving range of the operation plates 13 and 23 is defined by the depth length of the support frames 11 and 21. For this purpose, for example, the edges 11e and 21e of the support frames 11 and 21 serve as stoppers for the operation plates 13 and 23.

As shown in FIG. 11B, when the operating point 5c and the connecting pin 7b of the connecting rod 5 move, the wire 71 is tensioned by engaging with the guide pin 7c, and the operating rod 3a is moved to the door tail side. pull. As a result, the latch bolt 3 retracts against the spring 6 and is released from the latch.

(6) Sixth Embodiment FIG. 12 shows a sixth embodiment of the door operating device 10 of the present invention. The sixth embodiment is similar to the fifth embodiment, but the door 1 of the sixth embodiment is a door that can be opened on either side of both door surfaces 1a and 1b. be. 12 (a) is a cross-sectional view of the latch state of the sixth embodiment of the door operating device 10, and FIG. 12 (b) is a cross-sectional view of the latch state of the door operating device 10.

As shown in FIG. 12 (a), in the sixth embodiment, both sides of the door surfaces 1a and 1b are provided with the same configuration as the door surface 1b side of the fifth embodiment (FIG. 11). However, the operation plates 13 and 23 are arranged at the center of the depth lengths of the support frames 11 and 21, respectively. The operation plate 13 is provided with an auxiliary operation plate 14 via a support member 16, and the operation plate 23 is provided with an auxiliary operation plate 24 via a support member 26. The door operating device 10 has a mirror image-symmetrical configuration with the door 1 interposed therebetween. The conversion unit shown in FIG. 12 is an example, but the description thereof will be omitted because it is the same as that of the third embodiment shown in FIG.

FIG. 12B shows a state when the auxiliary operation plate 14 is pushed from the door surface 1a side as shown by the arrow m1 or the auxiliary operation plate 24 is pulled from the door surface 1b side as shown by the arrow m2. There is. By this push or pull operation, the operation plates 13 and 23 linearly move in the support frames 11 and 21, and the connecting rod 5 also linearly moves in the door through holes 1c and 1d. When the movement of the connecting rod 5 is transmitted to the operating rod 3a via the wire 71, the latch bolt 3 retracts and the latch is released. As a result, the door 1 can be opened toward the door surface 1b. Although not shown, on the contrary, when the door 1 is opened to the door surface 1a side, the auxiliary operation plate 14 is pulled from the door surface 1a side or the auxiliary operation plate 24 is pushed from the door surface 1b side.

Although not shown, as a modified form of the sixth embodiment, a form in which the same configuration as the door surface 1a side of the fifth embodiment (FIG. 11) is provided on both sides of the door surfaces 1a and 1b can be considered. Even in that case, the door operating device 10 has a mirror image-symmetrical configuration with the door 1 interposed therebetween. In this modified form, when the door 1 is opened to the door surface 1b side, the operation plate 13 is pushed on the door surface 1a side, and when the door 1 is opened to the door surface 1a side, the operation plate is operated on the door surface 1b side. Press 23 to perform the operation.

In the first to sixth embodiments, it is possible to remove the existing door handle and case (including the latch bolt) and install the door operating device 10 in place of them. In that case, it is preferable to embed the case 4 in the existing case embedding hole and use the mounting hole of the existing handle as the door through hole 1c and 1d to pass the connecting rod 5.

(7) Seventh Embodiment With reference to FIGS. 13 to 16, a seventh embodiment of the door operating device 10 of the present invention will be described. 13 (a) is a schematic perspective view of the door 1 to which the door operating device 10 of the seventh embodiment is attached as viewed from one door surface 1a, and FIG. 13 (b) is a schematic perspective view seen from the opposite door surface 1b. It is a schematic perspective view. The door 1 is a door that can be opened only on one side of both door surfaces 1a and 1b, in this case only on the side of the door surface 1b. For example, the door surface 1a faces the corridor side, and the door surface 1b faces the indoor side. FIG. 13 shows a state in which the door 1 is in the closed position.

The door operating device 10 of the seventh embodiment comprises components attached to the first and second door surfaces 1a and 1b facing each other in opposite directions. In the seventh embodiment, the door 1 itself remains in the existing state. That is, it is not necessary to remove the existing case 4 (built-in latch bolt 3) and the existing handles 50 and 60 from the door 1 in order to attach the door operating device 10. The door operating device 10 has a configuration suitable for the user to operate using a body part other than the fingers. The door operating device 10 is configured so that the door operating device 10 moves the handles 50 and 60 when the user operates the door operating device 10 to open the door. At that time, the handles 50 and 60 can move in the same manner as when the user directly operates the handles 50 and 60 using the fingers.

At the closed position of the door 1 shown in FIG. 13, the elastically urged latch bolt 3 protrudes from the case 4 and enters the opposing latch receiving hole (not shown). As a result, the door 1 is prevented from opening toward the door surface 1b.

The door operating device 10 has a first support frame 11 mounted on the first door surface 1a and a second door surface 1b as components mounted on the first and second door surfaces 1a and 1b. It has a second support frame 21 attached to the door. Preferably, the support frame 11 and the support frame 21 have substantially the same contour shape when viewed from a direction perpendicular to the door surface, and are mounted at substantially the same position. The method of attaching the support frames 11 and 21 to the door surfaces 1a and 1b is arbitrary, and for example, screwing or bonding can be used.

As an example, the first support frame 11 is composed of an upper part of the frame that supports the first operation plate 13 and a lower part of the frame that houses the first conversion unit 17. The operation plate 13 is rotatably attached together with the rotation shaft 12 around a first rotation shaft 12 provided in the vertical direction along the wall on the door tail side of the upper part of the frame. The operation plate 13 has a rectangular contour shape and is arranged parallel to the door surface 1a at the non-operation position shown in FIG.

On the other hand, the second support frame 21 is also composed of, for example, an upper part of the frame that supports the second operation plate 23 and a lower part of the frame that houses the second conversion unit 27. The operation plate 23 is rotatably attached together with the rotation shaft 22 around a second rotation shaft 22 provided in the vertical direction at an appropriate intermediate position between the door end side and the door end side of the upper part of the frame. Has been done. The operation plate 23 has a rectangular contour shape and is arranged perpendicular to the door surface 1b at the non-operation position in FIG. The second operation plate 23 does not have to be strictly perpendicular to the door surface 1b, and may be inclined, for example, by about −10 ° to + 10 ° with respect to the vertical position.

Specifically, the rotating shafts 12 and 22 are composed of, for example, one or a plurality of hinges. The shape of the upper part of each of the support frames 11 and 21 can be any shape as long as the operation plates 13 and 23 can be rotatably arranged.

The operation plates 13 and 23 have a large operation surface as compared with the existing handles 50 and 60. The contour shapes and sizes of the operation plates 13 and 23 are not limited to the illustrated examples. The contour shapes of the operation plates 13 and 23, the length in the vertical direction, the width in the horizontal direction, and the positions of the upper, lower, left, and right edges can be set in a wide range in consideration of ease of operation.

The lower part of each of the support frames 11 and 12 accommodates the conversion units 17 and 27 in the internal space thereof, respectively. The conversion unit 17 on the door surface 1a side has an operation rod 17a protruding downward from the lower surface of the support frame 11, and the lower end of the operation rod 17a is in contact with the handle 50. Similarly, the conversion unit 27 on the door surface 1b side has an operation rod 27a protruding downward from the lower surface of the support frame 21, and the lower end of the operation rod 27a is in contact with the handle 60. The handles 50 and 60 are lever handles as an example, but the door operating device of the present invention can be applied to handles other than the lever handles.

As another example (not shown), the lower frame of the support frames 11 and 12 may be configured to cover the operation rods 17a and 27a and the handles 50 and 60 as well.

14 (a) and 14 (b) are schematic perspective views corresponding to FIGS. 13 (a) and 13 (b), respectively, and show a state in which the door operating device 10 is operated to release the latch bolt 3. The arrow r1 shown in FIG. 14A indicates an operation in which the user pushes the operation plate 13 from the door surface 1a side. The arrow r2 shown in FIG. 14B indicates an operation in which the user pushes the operation plate 23 from the door surface 1b side.

By operating the operation plates 13 and 23 in this way, the operation plates 13 and 23 rotate around the rotation shafts 12 and 22, respectively, and the angles with respect to the door surfaces 1a and 1b change, respectively. The support frames 11 and 21 are formed with inclined surfaces that act as stoppers that limit the rotation of the operation plates 13 and 23, respectively.

The operation plates 13 and 23 to be operated have a large operation surface as compared with the existing handles 50 and 60. Therefore, the user can operate the operation plates 13 and 23 using body parts other than the fingers, for example, elbows, arms, shoulders, hips, legs, knees, and feet, which are convenient parts. Of course, it is also possible to operate using fingers. The operation plate 13 arranged on the support frame 11 can only be pushed. On the other hand, the operation plate 23 arranged on the support frame 21 can be operated to pull the edge portion of the operation plate 23 from the door tail side, for example, in addition to the operation of pushing the surface on the door end side as shown in the figure.

The conversion units 17 and 27 include a mechanism for converting the rotation of the operation plates 13 and 23, that is, the rotation of the rotation shafts 12 and 22, into the movement of the handles 50 and 60 (rotation in the case of a lever handle). There is. Therefore, when the user rotates the operation plates 13 and 23, the handles 50 and 60 are moved in the same manner as when they are directly operated. As a result, the latch bolt 3 is retracted against the elastic force and released. When the user subsequently applies further force to the operation plates 13 and 23, the door 1 can be opened as shown by the arrow R1. That is, the user can open the door 1 without using fingers.

The conversion units 17 and 27 will be described with reference to FIGS. 15 and 16. FIG. 15 schematically shows an example of the VI-VI cross section of FIG. 14 (b). 16 (a) is a diagram corresponding to FIG. 15 in the unlatched state, and FIG. 16 (b) is a diagram showing a part of the VII-VII cross section of (a).

At the latch position shown in FIG. 15, the latch bolt 3 is elastically urged and protrudes from the side surface of the case 4 on the door end side. The operating levers of the handles 50 and 60 extend in the horizontal direction. The support frames 11 and 21 of the door operation device 10 have operation plates 13 and 23 rotatably attached around the rotation shafts 12 and 22 to the frame upper portions 11a and 21a. In this embodiment, the rotation shafts 12 and 22 rotate together with the operation plates 13 and 23. The rotation range of the operation plates 13 and 23 is limited by the stopper surfaces 11a1 and 21a1.

The conversion units 17 and 27 are housed in the frame lower portions 11b and 21b of the support frames 11 and 21. The operation rods 17a and 27a projecting downward from the lower surfaces of the frame lower portions 11b and 21b are at the highest position in the vertical direction at the latch position. The lower ends of the operating rods 17a and 27a are in contact with the vicinity of the tips of the operating levers of the handles 50 and 60.

At the latch release position shown in FIG. 16A, the latch bolt 3 is retracted into the case 4 against the elastic force. This latch release position is realized by an operation of pushing the operation plate 13 as shown by the arrow r1 or an operation of pushing the operation plate 23 as shown by the arrow r2. FIG. 16A shows a state in which both the operation plates 13 and 23 are operated for the sake of explanation, but usually only one of them is operated. Then, only the operated operation plates 13 and 23 rotate together with the rotation shafts 12 and 22.

The VII-VII cross section of FIG. 16B schematically shows only the portion of the support frame 21 below the frame lower portion 21b. An example of the conversion unit 27 is schematically shown in the internal space of the frame lower portion 21b. Since the other conversion unit 17 has substantially the same configuration as the conversion unit 27, the description thereof will be omitted.

The lower end of the rotating shaft 22 extends within the frame lower portion 21b. A bevel gear 271 is provided at the lower end of the rotating shaft 22. The bevel gear 271 meshes with another bevel gear 272 having a horizontal axis. A pinion 273 is provided on the shaft of the bevel gear 272. The pinion 272 meshes with a rack 274 formed on one side surface of the operating rod 27a. By the mechanism of the conversion unit 27, the rotation r2 of the rotation shaft 22 is converted into the vertically downward movement m2 of the operation rod 27a.

When the operating rod 27a moves vertically, the operating lever of the handle 60 is pushed downward, and the handle 60 rotates as shown by the arrow r4. The movement of the handle 60 is the same as when the handle 60 is directly operated. Therefore, the latch is released by this.

Subsequently, when the user separates the body part from the door operating device 10, the door operating device 10 returns to the latch position of FIG. At this time, the latch bolt 3 returns to the initial position due to the restoring force of the spring (not shown) in the case 4, and at the same time, the operation plate 23 also returns to the initial position via the operation rod 27a and the conversion unit. In addition, in order to assist the restoring force of the spring in the case 4, another spring that elastically urges the operation plate to the initial position may be provided.

The mechanism of the conversion unit shown in FIG. 16B is an example, and the mechanism for converting the rotation of the operation plates 13 and 23 into the movement of the handles 50 and 60 is not limited to this. The conversion unit can be variously configured by appropriately combining cams, links, springs, gears, racks, and / or electric drives (the same applies to other similar embodiments).

Further, in the seventh embodiment, the rotating shafts 12 and 22 are vertical axes, but instead, the rotating shafts 12 and 22 can be used as horizontal axes. In that case, for example, the rotating shafts 12 and 22 can be attached along the upper end or the lower end of the frame upper portions 11a and 21a, respectively. Also in this case, the conversion units 17 and 27 are configured so that the rotation of the operation plates 13 and 23 is converted into the movement of the handles 50 and 60.

In the seventh embodiment, the conversion units 17 and 27 are arranged below the operation plates 13 and 23, but as another example, the positions and / or rotation shafts 12 and 22 of the operation plates 13 and 23 are arranged. The conversion units 17 and 27 may be provided above or to the side of the operation plates 13 and 23 depending on the orientation of the above.

(8) Eighth Embodiment FIG. 17A is a cross-sectional view of a latch state in the eighth embodiment of the door operating device 10, and corresponds to FIG. 15 of the seventh embodiment. FIG. 17B is a cross-sectional view of the latch released state.

The door operating device 10 of the eighth embodiment has the same configuration on both the door surfaces 1a and 1b. That is, the same configuration as the door surface 1a side of the seventh embodiment is provided on the door surface 1b side. Therefore, the door operating device 10 of the present embodiment has a mirror image-symmetrical configuration with the door 1 interposed therebetween.

As shown in FIG. 17B, the operation plate 13 is rotated from the door surface 1a side as shown by arrow r1, or the operation plate 23 is rotated from the door surface 1b side as shown by arrow r2. The operating rods 17a and 27a are moved vertically downward via the conversion units 17 and 27, and the handles 50 and 60 are moved as shown by the arrows r3 and r4 to be unlatched.

(9) Ninth Embodiment FIG. 18A is a cross-sectional view of a latch state in the ninth embodiment of the door operating device 10, and corresponds to FIG. 15 of the seventh embodiment. FIG. 18B is a cross-sectional view of the latch released state. The ninth embodiment is a modification of the eighth embodiment.

The door operating device 10 of the ninth embodiment has the same configuration on both the door surfaces 1a and 1b. That is, the same configuration as the door surface 1b side of the seventh embodiment is provided on the door surface 1a side. Therefore, the door operating device 10 of the present embodiment has a mirror image-symmetrical configuration with the door 1 interposed therebetween.

The operating rods 17a and 27a are moved vertically downward via the conversion units 17 and 27, and the handles 50 and 60 are moved as shown by the arrows r3 and r4 to release the latch.

(10) Tenth Embodiment With reference to FIGS. 19 and 20, a tenth embodiment of the door operating device 10 of the present invention will be described. Although the appearance of the entire door is omitted from the tenth embodiment, it is similar to the appearance of the entire door of the seventh embodiment shown in FIG. The door 1 of the tenth embodiment is a door that can be opened only on one side of both door surfaces 1a and 1b, in this case only on the side of the door surface 1b. The tenth embodiment is different from the seventh embodiment in that the operation plate moves linearly.

FIG. 19 is a cross-sectional view of the latch state of the tenth embodiment of the door operating device 10, and corresponds to FIG. 15 of the seventh embodiment. FIG. 20 is a cross-sectional view of the latch released state. At the latch position shown in FIG. 19, the latch bolt 3 protrudes from the side surface of the case 4 on the door end side and enters the facing latch receiving hole (not shown). As a result, the door 1 is prevented from opening toward the door surface 1b.

As shown in FIG. 19, the door operating device 10 has support frames 11 and 21 mounted on the door surfaces 1a and 1b. The shapes of the frame upper portions 11a and 21a of the support frames 11 and 21 are similar to, for example, the overall shape of the support frame 11 of the first embodiment shown in FIG. The frame lower portions 11b and 21b of the support frames 11 and 21 have an internal space for accommodating the conversion units 17 and 27 as in the seventh to ninth embodiments. In the cross section of FIG. 19, the upper surfaces of the frame lower portions 11b and 21b are visible.

The operation plates 13 and 23 are arranged in the upper portions 11a and 21a of the frame, respectively. The operation plates 13 and 23 have contour shapes that substantially fit into the internal spaces of the frame upper portions 11a and 21a, respectively, and have a thickness thinner than the depth length of the frame upper portions 11a and 21a. At the latch position of FIG. 19, the operation plate 13 is arranged on the front side in the depth direction of the frame upper portion 11a. On the other hand, the operation plate 23 is arranged on the back side in the depth direction of the frame upper portion 21a. Further, the operation plate 23 is provided with a support member 26 projecting in a direction perpendicular to the surface facing the opening side of the door 1, and an auxiliary operation plate 24 is provided at the tip of the support member 26.

The auxiliary operation plate 24 is attached so as to be substantially parallel to the operation plate 23. However, the auxiliary operation plate 24 does not have to be strictly parallel to the operation plate 23, and may be inclined by, for example, about −10 ° to + 10 ° with respect to the parallel position.

Preferably, the support member 26 is a rod-shaped member that protrudes from substantially the center of the operation plate 23. The support member 26 further protrudes from the opening of the support frame 21 by a predetermined length. For the total length of the support member 26, the user puts a body part such as an elbow or a foot in the gap between the operation plate 23 and the auxiliary operation plate 24, hooks it on the auxiliary operation plate 24, and pulls the auxiliary operation plate 24. Set to the extent that The size and contour shape of the auxiliary operation plate 24 are also appropriately set so as to be easy to operate. The contour shape of the auxiliary operation plate 24 is, for example, a circle. Further, it is preferable to provide a rounded rib 24a on the peripheral edge of the auxiliary operation plate 24 so that the user can easily hook the rib 24a.

The operation plates 13 and 23 are installed so as to be linearly movable in a direction perpendicular to the door surfaces 1a and 1b, respectively. For this purpose, a pair of rails 15 and 25 are formed on the floor surfaces of the frame upper portions 11a and 21a (upper surfaces of the frame lower portions 11b and 21b) in a direction perpendicular to the door surface, respectively. For example, the rails 15 and 25 are ridges, and a groove fitted to the rails 15 and 25 is formed on the lower surfaces of the opposing operation plates 13 and 23. Although not shown, it is preferable to provide similar rail mechanisms on the ceiling surfaces of the frame upper portions 11a and 21a and the upper surfaces of the operation plates 13 and 23. The mechanism for supporting the operation plates 13 and 23 by the support frames 11 and 21 and smoothly moving them linearly is not limited to this.

As an example, the contour shapes of the frame upper portions 11a and 21a and the operation plates 13 and 23 viewed from the direction perpendicular to the door surface are rectangular, but are not limited to rectangular. The contour shapes of the support frames 11 and 21 and the operation plates 13 and 23 may be circular or polygonal as long as the operation plates 13 and 23 can be supported and linearly moved by the support frames 11 and 21. ..

Further, rod-shaped transmission rods 18 and 28 projecting downward are formed on the lower surfaces of the operation plates 13 and 23, respectively. The transmission rods 18 and 28 penetrate the slits 19 and 29 formed on the floor surfaces of the frame upper portions 11a and 21a (upper surfaces of the frame lower portions 11b and 21b), respectively, and extend into the internal spaces of the frame lower portions 11b and 21b. There is. As the operation plates 13 and 23 move linearly, the transmission rods 18 and 28 also move linearly in the slits 19 and 29, respectively.

The latch release state shown in FIG. 20 is realized when the operation plate 13 is pushed from the door surface 1a side as shown by the arrow m1 or the auxiliary operation plate 24 is pulled from the door surface 1b side as shown by the arrow m2. .. By this push or pull operation, the operation plates 13 and 23 linearly move to the opposite ends in the frame upper portions 11a and 21a, respectively. As a result, the transmission rods 18 and 28 also move linearly in the slits 19 and 29, respectively.

Conversion units 17 and 27 are arranged in the lower portions 11b and 21b of the frame, respectively. The conversion units 17 and 27 are provided with a mechanism for converting the horizontal linear movement of the transmission rods 18 and 28 into the vertical downward movement of the operation rods 17a and 27a. As a result, the handles 50 and 60 rotate as shown by the reference numerals r3 and r4, respectively, and the latch bolt 3 is released.

(11) Eleventh Embodiment FIG. 21 is a cross-sectional view of a latch state of the eleventh embodiment of the door operating device 10, and is a cross-sectional view corresponding to FIG. 19 of the tenth embodiment. The eleventh embodiment is similar to the tenth embodiment. However, in the eleventh embodiment, the door 1 is a door that can be opened on either side of both door surfaces 1a and 1b.

The door operating device 10 of the eleventh embodiment has the same configuration on both the door surfaces 1a and 1b. That is, the same configuration as the door surface 1a side of the tenth embodiment is provided on the door surface 1b side. Therefore, the door operating device 10 of the present embodiment has a mirror image-symmetrical configuration with the door 1 interposed therebetween.

In the eleventh embodiment, in order to release the latch, the operation plate 13 is pushed from the door surface 1a side, or the operation plate 23 is pushed from the door surface 1b side. Regardless of which operation is performed, the latch is released in the same manner as the operation on the door surface 1a side shown in FIG.

(12) Twelfth Embodiment FIG. 22 is a cross-sectional view of a latch state of the twelfth embodiment of the door operating device 10. The twelfth embodiment is a modification of the eleventh embodiment.

The door operating device 10 of the twelfth embodiment has the same configuration on both the door surfaces 1a and 1b. Here, the same configuration as the door surface 1b side of the tenth embodiment is provided on the door surface 1a side. Therefore, the door operating device 10 of the present embodiment has a mirror image-symmetrical configuration with the door 1 interposed therebetween. However, the operation plates 13 and 23 are arranged at the center of the depth lengths of the frame upper portions 11a and 21a, respectively. The operation plate 13 is provided with an auxiliary operation plate 14 via a support member 16, and the operation plate 23 is provided with an auxiliary operation plate 24 via a support member 26. The door operating device 10 has a mirror image-symmetrical configuration with the door 1 interposed therebetween.

In the twelfth embodiment, in order to release the latch, the auxiliary operation plate 14 is pushed or pulled from the door surface 1a side, or the auxiliary operation plate 24 is pushed or pulled from the door surface 1b side.

(13) Thirteenth Embodiment The thirteenth embodiment of the present invention will be described with reference to FIGS. 23 (a) to 23 (c). FIG. 23A is a schematic perspective view showing the appearance of a general doorknob 60A. When the door operating device of the present invention is applied to such a door knob 60A, the attachment 45 shown in FIG. 23 (b) is used. The attachment 45 is a component included in the conversion unit of the door operating device of the present invention. The attachment 45 has an annular fixing portion 45a that surrounds and is fixed around the door knob 60A, and a lever portion 45b that protrudes in the radial direction from one location on the periphery of the annular fixing portion 45a. The lower end of the operation rod 27a of the conversion unit is in contact with the upper surface near the tip of the lever portion 45b.

As shown in FIG. 23 (c), when the door operating device is operated, the operating rod 27a moves vertically downward and pushes down the lever portion 45b of the attachment 45. The lever portion 45b plays the same role as the operating lever in the lever handle. As a result, the doorknob 60A rotates as shown by the arrow r4 and is released from the latch.

In the seventh to twelfth embodiments, the door operating device 10 can be installed while maintaining the existing door handle and case (including the latch bolt). In the above-mentioned example, only the form in which the operation rod of the conversion unit pushes down the lever handle from above is shown, but instead, the operation rod of the conversion unit may be in the form of pulling down the lever handle from below. If the existing handle is a push-pull handle, the push-pull handle can be moved by moving the operation rod of the conversion unit in the horizontal direction.

When the door operation device 10 is installed while maintaining the handle of the existing door, the existing handle has various distances and shapes from the door surface, so that the positional relationship between the operation rod 27a of the conversion unit and the existing handle is different. Not always optimal. In that case, a form in which an attachment for transmitting a force is interposed between the operation rod 27a of the conversion unit and the existing handle is effective. Such an attachment may be an extension of the operating rod, or it may be attached to a handle as in the thirteenth embodiment. Such an attachment is regarded as one of the components of the conversion unit. Therefore, the door operating device 10 of the present invention is not limited to the form in which the operating rod 27a of the conversion unit acts directly on the existing handle, but also includes the form in which the operating rod 27a acts indirectly.

In the embodiment of the seventh to twelfth embodiments, a wire-shaped member and a weight attached to the lower end thereof may be used instead of the operation rod 27a of the conversion unit. The weight of the weight is set so that the lever handle rotates when the weight is applied to the lever handle. Further, the conversion unit is provided with a mechanism for suspending the wire-shaped member to which the weight is attached so that the weight of the weight is not applied to the lever handle when not operated. For example, a spring that elastically urges the operation plates 13 and 23 so as to maintain the operation plates 13 and 23 in a non-operation position by a force larger than the weight of the weight is provided at an appropriate position. When the user operates the operation plates 13 and 23 against the elastic force, the weight of the weight is applied to the lever handle. Such a mechanism is also regarded as one of the components of the conversion unit.

(14) Other Embodiments In each of the above-described embodiments, it is preferable that the operation plate and / or the auxiliary operation plate is sufficiently large so as to facilitate the operation by the user. For example, the vertical length of the operation plate or auxiliary operation plate is preferably between 0.3 and 0.8 times the door height (for example, 180 cm to 270 cm). Further, for example, the horizontal length of the rectangular operation plate or the auxiliary operation plate or the diameter of the circular operation plate or the auxiliary operation plate is between 0.2 to 0.6 times the door width (for example, 60 cm to 130 cm). Is preferable. Further, when the user operates with his / her feet, it is preferable that the operation plate or the auxiliary operation plate is located at a position lower than a quarter height from the bottom of the door height.

In some embodiments, the auxiliary operating plate is arranged approximately perpendicular to the operating plate. Therefore, if a load that greatly exceeds the force for pushing the auxiliary operation plate during normal operation is applied, the mounting portion of the auxiliary operation plate may be damaged. To prevent this, the auxiliary operating plate can tilt toward the operating plate when overloaded, and when the overload is removed, the auxiliary operating plate stands up again and returns to its original position. It is preferable to provide a structure that can be formed at the connection portion between the operation plate and the auxiliary operation plate. Such an overload prevention mechanism is well known.

Since the operation plate or auxiliary operation plate of each embodiment is a flat plate having a relatively wide surface, it is easy to perform cleaning and alcohol disinfection.

Of course, the operation plate or auxiliary operation plate of each embodiment can be operated by fingers. However, the user can easily operate it by using other than fingers.

Although the present invention has been described above with reference to the drawings showing some embodiments of the present invention, the present invention also includes embodiments in which the characteristic configurations of the respective embodiments are combined. Further, as long as it is in line with the gist of the present invention, a wider variety of modified forms are possible.
