In the above-mentioned, since it is necessary to provide a dead bolt or a locking means that is interlocked with the operation of the thumb turn in the latch lock device, the thumb turn that is connected to these via the connecting means or the like is connected to the pivot shaft of the lever handle. Therefore, it was necessary to provide them relatively apart from each other. For this reason, when a thumb turn is provided in a seat in which an opening for receiving the pivot base of the lever handle is provided, it is necessary to make the seat relatively large, and the balance with the size of the lever handle becomes poor and the appearance is poor. There was a problem.
On the other hand, there is a structure in which the lever handle seat is made relatively small and the thumb turn is provided separately from the seat.
However, in such a case, two processed holes for the lever handle and the thumb turn are formed on the surface of the door. Therefore, when the machined hole is formed in the door in advance, the empty lock without the locking mechanism that requires only one machined hole and the partition lock with the lock mechanism that requires two machined holes ( There is also a problem that it is difficult to change the display lock) on site.

In the following Patent Document 1, by rotating the knob provided on the surface side of the seat plate (receiving seat), the lock piece provided continuously with the knob moves the inner space of the seat plate between the lock side and the release side. A latch lock with a lock mechanism is proposed that is configured to restrict the pivoting operation of the lever handle by restricting the protruding piece of the rotating board that is connected to the square core of the handle. ing.

Further, as shown in FIG. 10, the back end of the release pin 23 is a contact portion 23a that contacts one of the spring pieces 14L and 14R of the cushion spring member 14 described above. As will be described later, when the unlocking operation is performed from the outer space 8 side, the release pin 23 is pushed in toward the back side so that the surface thereof and the surface of the seat body 21 are at least approximately. In a flat state, it is formed in an appropriate length so that the lock is not released.

The seat main body 21 has a substantially bottomed cylindrical shape like the above-described inner seat 10, and the rotation fulcrum of the lever handles 30, 40 is circular at the approximate center on the surface side corresponding to the bottom. A circular handle receiving opening 21a as a center is formed. The rotation base 41 of the outer lever handle 40 is fitted into the handle receiving opening 21a with a handle base washer 29 interposed.
In addition, the display button guide hole 21b in which the display button 22 is accommodated has a shape corresponding to the shape of the display button 22, and is provided at substantially the same height as the rotation fulcrum of the lever handles 30 and 40. The handle receiving opening 21a is provided so as to be positioned on either side of the left or right side portion of the handle receiving opening 21a, that is, on the door-end side of the lever handles 30 and 40 when attached to the door panel 50 (see also FIG. 1). ).
The depth of the display button guide hole 21b can accommodate the entire display button 22 corresponding to the shape of the display button 22, and when the display button 22 is pushed, the surface thereof is the surface of the seat body 21. It is set so as to be located inward (back side).

As shown in FIG. 8, a pair of screw bases extending toward the back side is formed on the back side of the seat body 21. A pair of female screw holes 21c and 21c are formed in the pair of screw bases. The pair of female screw holes 21c and 21c are screwed with male screw portions 25a and 25a provided at the front end portions of a pair of screw columns 25 and 25 respectively having female screw holes 25b and 25b formed on the back side. The pair of screw pillars 25, 25 are coupled.
In addition, it replaces with the structure which provides a pair of screw pillars 25 and 25 as a separate body in this way, It is good also as what was formed in the back side of the receiving body 21 integrally with the substantially same thing as these.
The pair of female screw holes 21c and 21c are formed symmetrically like the pair of countersunk holes 11c and 11c of the inner receiving seat 10 with the handle receiving opening 21a interposed therebetween, and the pair of countersunk holes 11c. , 11c (see also FIG. 1B).

Further, as shown in FIG. 8B, one of the pair of screw bases in which the pair of female screw holes 21c and 21c are respectively formed corresponds to the diameter of the large-diameter restricting portion 23c of the release pin 23. The large-diameter pin guide hole 21e and the small-diameter pin guide hole 21d corresponding to the diameter of the near-side portion smaller than the large-diameter restricting portion 23c are arranged in this order from the back side to the surface side. It is formed in communication with the guide hole 21b.
Further, the release spring 24 is formed of, for example, a compression coil spring and is externally mounted on a front side portion having a smaller diameter than the large-diameter restricting portion 23c of the release pin 23. The front side of the release spring 24 is regulated by a step portion of a large-diameter pin guide hole 21e and a small-diameter pin guide hole 21d, and the back side thereof is regulated by a large-diameter regulating portion 23c of the release pin 23.
The outer peripheral diameter of the seat body 21 of the outer seat 20 may be substantially the same as the outer diameter of the seat body 11 of the inner seat 10 described above from the viewpoint of design. Further, the thickness of the seat body 21 of the outer seat 20 does not need to be provided with various locking mechanisms as described above, so that it is made thinner than the seat body 11 of the inner seat 10. Also good.

The outer seat 20 having the above-described configuration accommodates the display button 22 in the display button guide hole 21b of the seat body 21, and the release pin 23 having the release spring 24 on the front side portion is provided in the large-diameter pin guide hole 21e. Alternatively, the front portion may be inserted into the small-diameter pin guide hole 21d and the front end portion 23b may be press-fitted into the fitting hole 22b of the display button 22 and assembled.
In the assembled state, the release pin 23 is urged toward the back side by the release spring 24. The release spring 24 and the pair of spring pieces 14L and 14R of the cushion spring member 14 are set so that the spring constant of the pair of spring pieces 14L and 14R is larger than the spring constant of the release spring 24. Has been.

As shown in FIG. 9, the inner seat 10 and the outer seat 20 assembled as described above may be arranged to face each other with the door panel 50 interposed therebetween, and may be assembled as follows.
The inner seat 10 is disposed in the processing hole on the inner surface 51 side of the door panel 50. At this time, the positioning protrusion 16f provided on the inner receiving seat 10 may be engaged with the lower end edge of the machining hole for positioning.
In addition, the pair of screw pillars 25 and 25 and the release pin 23 of the outer seat 20 are latched to the latch panel 60 accommodated in the door panel 50 through the processing hole 54 provided in the door panel 50 from the outer surface 52 side. Are inserted into the through-holes or cut-out portions, and protruded toward the inner side surface 51 to be engaged with the inner receiving seat 10. That is, as shown in FIG. 1B, the release pin 23 is inserted into one of the pin insertion holes 16 b and 16 b (the door end side in the illustrated example) of the back plate 16 of the inner receiving seat 10. Further, the pair of screw pillars 25 and 25 are brought close to the thick part of the receiving body 11 through the notches 16c and 16c (see FIG. 5G) of the back plate 16 of the inner receiving seat 10. Are positioned so that the female screw holes 25b, 25b are aligned with a pair of countersunk holes 11c, 11c provided in the seat body 11.

Next, a fixing stopper B such as a countersunk screw (see FIG. 1A) is inserted into the pair of countersunk holes 11c and 11c, and screwed into the female screw holes 25b and 25b of the pair of screw columns 25 and 25, respectively. The inner receiving seat 10 and the outer receiving seat 20 may be connected to each other and attached to the door panel 50.
Further, as described above, the rotating base portions 31 and 41 of the pair of lever handles 30 and 40 are fitted into the handle receiving openings 11a and 21a of the receiving seats 10 and 20 attached to the door panel 50 as described above. In addition, the handle device 2 may be assembled to the door panel 50 by coupling the pair of lever handles 30 and 40 via the connecting shaft 45.
The connection between the inner receiving seat 10 and the outer receiving seat 20 is not limited to the embodiment using the fixed stopper B such as a countersunk screw and the pair of screw columns 25, 25, but is connected by an appropriate connecting means. You may make it carry out, or you may make it fix each with respect to a door panel with a fixing stopper, without connecting each seat.

Next, FIG. 1, FIG. 2 and FIG. 10 show the locked state, unlocking operation, unlocking state, locking operation and unlocking operation at the time of emergency release of the door 1 provided with the handle device 2 configured as described above. This will be explained based on.
In addition, below, it demonstrates on the basis of the state in which the door 1 was closed.

<Locked state>
As shown in FIG. 1, when the left operation portion (lock operation portion) 12 </ b> L of the operation switch 12 is pushed, the left lock piece of the switch base 13 coupled to the operation switch 12 via the switch shaft 18. The portion 13L is positioned on the back side (the outer space 8 side) with respect to the other right lock piece portion 13R, and is engaged with the left rotation restricting engagement portion 15L of the rotation restricting disc 15.
In this state, the rotation of the lever handles 30, 40 toward the door opening side is locked. That is, the rotation of the rotation restricting disc 15 attached to the connecting shaft 45 of the lever handles 30 and 40 toward the door opening (clockwise rotation in FIG. 1A) is the left rotation restricting member. It is regulated by the left lock piece 13L of the switch base 13 engaged with the joint portion 15L. In this state, the right rotation restriction engagement portion 15R of the rotation restriction disk 15 and the right lock piece portion 13R of the switch base 13 are in a disengaged state. Although rotation to the counter-opening door side (counterclockwise rotation in FIG. 1A) is not restricted by the switch base 13, as described above, the connecting shaft 45 ( Substantially, the rotation of the hub 64) into which the connecting shaft 45 is inserted into the counter-opening door is restricted. Therefore, in this locked state, the lever handles 30 and 40 are in a state where the rotation in both directions is restricted.
Further, in this state, as shown in FIG. 10A, one side surface of the engagement protrusion 13d of the switch base 13 coupled to the operation switch 12 abuts one side surface of the spring protrusion 17a of the moderation spring member 17. In this way, the operation switch 12 is regulated so as not to easily rotate to the unlocking side.

Further, the left spring piece 14L of the cushion spring member 14 coupled to the operation switch 12 via the switch shaft 18 is located on the outer space 8 side with respect to the other right spring piece 14R, and the release pin 23 is contacted. It abuts or elastically contacts the contact portion 23a.
In this state, the release spring 24 mounted on the release pin 23 is compressed with elastic deformation, and the display portion 22 a of the display button 22 connected to the release pin 23 is connected to the outer seat 20. It will be in the state which protruded from the surface of the receiving body 21. FIG. Thus, in the locked state, by providing the display button 22 having the display portion 22a protruding from the surface of the outer receiving seat 20, the locked state of the door 1 can be easily identified from the outer space 8 side. Can do. In particular, the locked state can be more easily identified by coloring the display portion 22a of the display button 22 as described above. Further, since the display button 22 is provided on the door end side of the receiving body 21, it is not concealed by the outer lever handle 40, and the display portion 22a of the display button 22 is easy to see and stand out. it can. Furthermore, in the present embodiment, the display button 22 also functions as an emergency release operation unit. Therefore, by providing the display button 22 at such a position, it is possible to improve operability during an emergency release operation described later.

<Unlock operation>
If the right operation part (release operation part) 12R of the operation switch 12 is pushed in the locked state, the operation switch 12 is released from the lock side with the switch shaft 18 as a pivot as shown in FIG. Rotate to the side (counterclockwise rotation in FIG. 10). At this time, with the elastic deformation of the moderation spring member 17, the engagement protrusion 13d of the switch base 13 moves over the spring protrusion 17a and moves to the release side.
In conjunction with the movement of the operation switch 12, the left lock piece 13 </ b> L of the switch base 13 and the left spring piece 14 </ b> L of the cushion spring member 14 generally extend along the axial direction of the connecting shaft 45 (inner side). Move to the space 9 side). Here, similarly to the operation switch 12, the switch base 13 and the cushion spring member 14 are rotated about the switch shaft 18 as a rotation fulcrum, and by this rotation, the left lock piece 13L and the cushion spring member of the switch base 13 are rotated. Similarly, the left-side spring piece 14L of 14 also moves around the rotation fulcrum, but since the amount of movement is relatively small, such movement is also generally along the axial direction of the connecting shaft 45.
Due to the movement of the left lock piece 13L of the switch base 13 and the left spring piece 14L of the cushion spring member 14, the release spring 24 is elastically restored, and the release pin 23 biased thereby is directed toward the inner space 9 side. The display button 22 connected thereto moves in the display button guide hole 21b of the outer seat 20 in the immersion direction.

<Unlocked state>
When unlocked by the above-described unlocking operation, as shown in FIGS. 2 and 10C, the right lock piece portion 13R of the switch base 13 is located in the outer space 8 than the other left lock piece portion 13L. It is located on the side and engages with the right-side rotation restricting engagement portion 15 </ b> R of the rotation restricting disc 15. That is, in this state, the left lock piece 13L is positioned closer to the inner space 9 than the other right lock piece 13R, and the left rotation restriction engagement portion 15L and the left lock piece 13L of the rotation restriction disk 15 are located. Is in a disengaged state.
In this state, the left rotation restricting engagement portion 15L of the rotation restricting disc 15 attached to the connecting shaft 45 of the lever handles 30 and 40 is not restricted by the left lock piece 13L of the switch base 13, and the rotation is prevented. The movement restricting disk 15 can be turned to the door opening side (clockwise turning in FIG. 2A), and the door 1 can be opened.

Further, in this state, as shown in FIG. 10C, the other side surface of the engagement protrusion 13d of the switch base 13 is in contact with or elastically in contact with the other side surface of the spring protrusion 17a of the moderation spring member 17. Thereby, the operation switch 12 is restricted so as not to easily rotate to the lock side.
Further, the contact portion 23a of the release pin 23 contacts or elastically contacts the left spring piece 14L of the cushion spring member 14 positioned on the inner space 9 side with respect to the other right spring piece 14R. 23, the display button 22 connected to 23 is immersed, and the unlocked state of the door 1 can be identified from the outer space 8 side.

<Lock operation>
In the unlocked state, when the left operation portion (lock operation portion) 12L of the operation switch 12 is pressed, that is, when the lock operation is performed, each portion moves to the opposite side to the unlock operation.
That is, as shown in FIG. 10, the operation switch 12 rotates from the release side to the lock side (clockwise rotation in FIG. 10) using the switch shaft 18 as a rotation fulcrum. At this time, with the elastic deformation of the moderation spring member 17, the engagement protrusion 13d of the switch base 13 moves over the spring protrusion 17a and moves to the lock side.
In conjunction with the movement of the operation switch 12, the left lock piece 13L of the switch base 13 and the left spring piece 14L of the cushion spring member 14 move to the outer space 8 side, accompanied by elastic deformation of the release spring 24. The release pin 23 moves toward the outer space 8 side. Thereby, the display button 22 connected to the release pin 23 moves in the display button guide hole 21b of the outer seat 20 in the protruding direction.
This lock operation results in the locked state.

<Emergency release operation>
On the other hand, when releasing the locked state from the outer space 8 side in the locked state, the display button 22 can be used as follows.
As shown in FIG. 10A, the display portion 22a of the display button 22 that is in the locked state and protrudes from the surface of the seat body 21 of the outer seat 20 is pushed toward the inner space 9 side. By pushing the display button 22, the release pin 23 moves toward the inner space 9 side.
The movement of the release pin 23 causes the left spring piece 14L of the cushion spring member 14 to be elastically deformed. On the other hand, the switch base 13 is restricted from moving toward the lock release side by the engagement spring 13d of the engagement protrusion 13d. It is in the state. That is, the spring of the moderation spring member 17 that restricts the movement by urging the engagement protrusion 13d of the switch base 13 toward the lock side or the unlock side rather than the urging force of the spring pieces 14L and 14R of the cushion spring member 14. The urging force of the ridge 17a is set to be large.

As shown in FIG. 10 (b), the surface of the display button 22 is substantially flush with the surface of the receiving body 21 of the outer receiving seat 20 or slightly inward from the surface of the receiving body 21. Until it is positioned, the movement of the release pin 23 is not directly transmitted to the switch base 13 due to the above-described deformation allowance of the left spring piece 14L of the cushion spring member 14, and the left lock piece of the switch base 13 is not transmitted. At least a part of 13L is in a state of being engaged with the left-side rotation restricting engagement portion 15L of the rotation restricting disc 15.
From the above state, as shown in FIG. 10C, if the display button 22 is pushed further inward (inner space 9 side) than the surface of the seat body 21 of the outer seat 20, the release pin 23 further moves toward the inner space 9, and the left locking piece 13 </ b> L of the switch base 13 is pushed to the unlocking side while elastically deforming the moderation spring member 17, and the left turn of the rotation restricting disk 15. The engagement state between the movement restricting engagement portion 15L and the left lock piece portion 13L is released. As described above, the push-in operation of the display button 22 inward is configured so as not to be easily performed with a finger or the like, so that the push-in operation is performed with a rod-shaped pin member or the like. Also good.
In conjunction with the movement of the switch base 13, the operation switch 12 is similarly turned from the lock side to the release side, and the lock release state, that is, the release operation portion 12 R side is pushed.

As described above, since the unlocking operation can be performed from the outer space 8 side by pushing the display button 22 as the emergency release operation unit, it is necessary to perform a rotation operation with a driver, a coin or the like. Compared with the operation unit, the operability can be improved.
Further, since the display button 22 protruding from the surface of the receiving body 21 of the outer receiving seat 20 in the locked state, that is, the display portion 22a is simply pushed inward, the unlocking is not performed. Easy unlocking from the space 8 side can be prevented. In particular, in this embodiment, when the pressing operation of the display button 22 is performed, the urging force of the cushion spring member 14 and the moderation spring member 17 is acting, so that easy unlocking is more effectively prevented. be able to.
Furthermore, since the release operation by the push-in operation of the display button 22 is performed by pushing one of the lock pieces 13L and 13R by the release pin 23, the release mechanism can have a simple configuration and can be moved straight along the axial direction. Since it can be released by movement, the release mechanism is hardly damaged.

As described above, according to the handle device 2 according to the present embodiment, it can be locked and released by pressing the operation switch 12, so that compared to a conventional operation of rotating a knob or the like, The operability during the lock operation and the release operation can be improved.
Further, even when the operation switch 12 is provided at a position relatively close to the inner lever handle 30 as in the present embodiment, the operability is good, so that the seat must be enlarged to provide a thumb turn. In combination with the absence of this, the inner seat 10 provided with the operation switch 12 can be made compact and efficient.

Furthermore, since a pair of lock pieces 13L, 13R and a pair of rotation restricting engagement portions 15L, 15R constituting a lock mechanism are provided in one of the seats (inner seat 10 in the illustrated example), There is no need to provide locking means in the latch lock device, and there is no need for a processing hole for providing the thumb turn as a separate body. Therefore, regardless of the type of the latch lock device, the handle device for the empty lock type door that does not have the lock mechanism can be changed to the handle device 2 having the lock mechanism according to the present embodiment. It becomes possible.
Moreover, since the outer receiving seat 20 can be made relatively thin and compact by providing the locking mechanism in the inner receiving seat 10, the appearance from the outer space 8 is good.
