Technical Field

The present invention relates to a handle device.

The present application is based on the priority claim of Japanese patent application 2019-15678 filed in Japan on 31.1.2019, the contents of which are incorporated herein by reference.

Background

A handle device is provided in a partition where a door latch is provided in a door leaf. The handle device operates a latch in conjunction with the operation of a handle operated by a user when opening and closing the door.

In the handle devices disclosed in patent documents 1 and 2, the latch is configured to be rotated by pushing and pulling the operating handle.

Disclosure of Invention

Technical problem to be solved by the invention

In order to rotate the latch by pushing and pulling the handle, a conversion mechanism for converting the movement of the handle into the movement of the latch in the rotation direction needs to be provided. If such a conversion mechanism is provided separately for the handle and the latch in the handle device, the number of parts increases and the size increases, which may impair the appearance.

The present invention aims to provide a handle device that can rotate a latch by pushing and pulling a handle, and can reduce the number of components to achieve compactness.

Means for solving the problems

The handle device of the present invention is mounted to a partition including a frame portion mounted to an edge portion of an opening portion and a door mounted to an inner side of the frame portion to open and close the opening portion, and includes: a handle portion provided to the door leaf and capable of being pushed and pulled in an expected direction; a latch unit provided on the door, configured to directly abut against the handle unit and to transmit the pushing and pulling operation of the handle unit in the expected direction, and configured to rotate around a rotation axis extending in the expected direction and to protrude/retract from/into an end surface of the door if the pushing and pulling operation of the handle unit in the expected direction is transmitted; a latch receiving portion that is provided in the frame portion and that latches the latch portion protruding from an end surface of the door; the latch portion is formed in a rod shape, the pivot shaft is located at a halfway position in a longitudinal direction of the latch portion, and if the latch portion is pivoted about the pivot shaft and is brought into a posture of extending obliquely with respect to a vertical direction, the latch portion protrudes from an end surface of the door leaf and is locked to the latch receiving portion, and if the latch portion is pivoted about the pivot shaft and is brought into a posture of extending in the vertical direction, the latch portion is accommodated in an inner portion of the door leaf and the locking of the latch receiving portion is released.

In the present invention, the push-pull operation of the handle portion in the desired direction is directly transmitted from the handle portion to the latch portion by directly contacting the handle portion with the latch portion, and the latch portion is rotated. The latch section is locked to the latch receiving section when the latch section is in a posture inclined with respect to the vertical direction, and the lock of the latch receiving section is released when the latch section is in a posture extending in the vertical direction.

Therefore, when the latch portion is switched between the state of being locked to the latch receiving portion and the state of not being locked to the latch receiving portion, the latch portion does not need to be rotated greatly, and only a small operation of pushing and pulling the handle portion in an intended direction is required.

In this way, since the handle portion abuts against the latch portion and the latch portion can be rotated by a small operation of the handle portion, a mechanism for converting the push-pull operation of the handle portion in an intended direction to rotate the latch portion can be simply configured. As a result, the number of components of the handle device can be reduced and the handle device can be made compact.

In the handle device of the present invention, the latch unit may include: a latched portion provided at a first end portion in the longitudinal direction and latched by the latch receiving portion; a handle operation action part which is arranged at the second end part in the length direction and is acted on the push-pull action of the handle part in the expected direction; the pivot shaft is disposed between the engaged portion and the handle operation acting portion, and a distance from the pivot shaft to the engaged portion is set to be longer than a distance from the pivot shaft to the handle operation acting portion.

With this configuration, even if the operation of the handle operation acting portion is small, the engaged portion can be reliably rotated.

In the handle device of the present invention, the latch unit may include: a latched portion provided at a first end portion in the longitudinal direction and latched by the latch receiving portion; a handle operation action part which is arranged at the second end part in the length direction and is acted on the push-pull action of the handle part in the expected direction; the handle operation action portion has an inclined surface on at least one surface in the expected direction, and the handle portion has a latch abutting portion capable of abutting against the inclined surface.

With this configuration, the latch abutting portion of the handle portion directly acts on the inclined surface of the handle operation acting portion. As a result, the push-pull operation of the handle portion in the desired direction can be switched without providing a complicated mechanism, and the latch portion can be rotated.

In the handle device of the present invention, the inclined surface may have a first inclined surface provided on a first surface of the handle operation acting portion in the expected direction and a second inclined surface provided on a second surface of the handle operation acting portion in the expected direction, the latch abutting portion may have a first latch abutting portion capable of abutting against the first inclined surface and a second latch abutting portion capable of abutting against the second inclined surface, and the first latch abutting portion and the second latch abutting portion may be arranged to sandwich the handle operation acting portion from the expected direction.

With this configuration, the push-pull operation of the handle portion to both sides in the expected direction can be switched, and the latch portion can be rotated.

Effects of the invention

According to the present invention, the latch portion can be pivoted by pushing and pulling the handle portion, and the number of components of the handle device can be reduced to make the handle device compact.

When the latch main body 31 is in the latch protruding state, the handle main body 21 is arranged at the first position.

In the latch projecting state, the first contact surface 264 of the first latch contact portion 261 of the handle body 21 contacts the first inclined surface 341 of the handle operation acting portion 34 of the latch body 31, and the second contact surface 265 of the second latch contact portion 262 contacts the second inclined surface 342.

If the handle main body 21 disposed at the first position is directed to the outdoor space 17 side with respect to the handle main body support portion 22 by the operation of the user (the operation of pressing or pulling the handle main body 21), the first contact surface 264 of the handle main body 21 moves to the outdoor space 17 side and presses the first inclined surface 341 of the handle operation acting portion 34. Thereby, the second contact surface 265 of the handle main body 21 moves toward the outdoor unit 17 and separates from the second inclined surface 342 of the handle operation acting portion 34. If the first contact surface 264 of the handle body 21 presses the first inclined surface 341 of the handle operation operating portion 34, the first inclined surface 341 is an inclined surface gradually heading from the indoor 16 side to the outdoor 17 side toward the rear side, and the first latch contact portion 261 presses the first inclined surface 341 from the indoor 16 side and the front side. Therefore, the first contact surface 264 is applied with a force toward the outdoor unit 17 and the front side.

Thereby, the handle operation acting portion 34 is pressed forward, and the latch main body 31 is rotated. As shown in fig. 7 and 10, if the handle body 21 reaches the second position, the first latch abutting portion 261 is disposed on the rear side of the handle operation acting portion 34. Therefore, the handle operation operating portion 34 is in a state of being unable to move to a position further to the rear side than the first latch abutting portion 261. Thereby, the latch main body 31 becomes a latch non-protruding state.

In a state where the door 15 closes the opening 12, if the latch body 31 is in a latch non-protruding state, the engaged portion 35 of the latch body 31 is in a state of being pulled out from the latch insertion hole portion 43 of the latch receiving portion 4. Thus, the door leaf 15 is opened. If the latch body 31 is in the latch non-projecting state, the rear side of the engaged portion 35 is inserted into the second groove portion 281 of the second support member 28, the gap between the first grip portion 23 and the second grip portion 24 of the handle body 21, and the first groove portion 296 of the rod-shaped portion 291 of the first support member 27.

When the handle main body 21 disposed at the first position is directed toward the indoor space 16 side with respect to the handle main body support portion 22 by the operation of the user (the operation of pressing or pulling the handle main body 21), the second contact surface 265 of the handle main body 21 moves toward the indoor space 16 side and presses the second inclined surface 342 of the handle operation acting portion 34. Thereby, the first contact surface 264 of the handle main body 21 moves toward the indoor space 16 and separates from the first inclined surface 341 of the handle operation acting portion 34. If the second contact surface 265 of the handle body 21 presses the second inclined surface 342 of the handle operation operating portion 34, the second inclined surface 342 is an inclined surface gradually facing the rear side from the outdoor unit 17 side to the indoor unit 16 side, and the second latch contact portion 262 presses the second inclined surface 342 from the outdoor unit 17 side and the front side. Therefore, the second contact surface 265 is applied with forces toward the indoor 16 side and the front side.

Thereby, the handle operation acting portion 34 is pressed forward, and the latch main body 31 is rotated. As shown in fig. 8, if the handle body 21 reaches the third position, the second latch abutting portion 262 is disposed on the rear side of the handle operation acting portion 34. Therefore, the handle operation operating portion 34 is in a state of being unable to move to a position further to the rear side than the second latch abutting portion 262. Thereby, the latch main body 31 becomes the latch non-projecting state in the same posture as that shown in fig. 10.

In a state where the door 15 closes the opening 12, if the latch body 31 is in a latch non-protruding state, the engaged portion 35 of the latch body 31 is in a state of being pulled out from the latch insertion hole portion 43 of the latch receiving portion 4, and therefore the door 15 is opened.

In either case of moving the handle main body 21 to the second position to open the door 15 or moving the handle main body 21 to the third position to open the door 15, the door 15 is in a state of opening the opening 12, and if the user stops the operation of the handle main body 21, the handle main body 21 is returned to the first position by the urging force of the spring.

When the handle main body 21 is moved to the first position, the latch abutting groove portion 263 is disposed on the rear side of the handle operation acting portion 34, and the handle operation acting portion 34 can be inserted into the latch abutting groove portion 263. Therefore, the handle operation acting portion 34 is turned so as to move to the rear side, and the latch is brought into a latch projecting state.

When the door 15 that opens the opening 12 is closed, the handle body 21 is operated to move the door 15 in the closing direction. At this time, the latch main body 31 becomes the latch non-projecting state by moving the handle main body 21 to the second position or the third position by operating the handle main body 21. If the door leaf 15 with the latch body 31 in the latch non-protruding state closes the opening portion 12 and the handle body 21 is restored to the first position, the latch body 31 becomes the latch protruding state and is inserted into the latch insertion hole portion 43 of the latch receiving portion 4.

Next, the operation and effect of the handle device 1 of the present embodiment described above will be described with reference to the drawings.

In the handle device 1 of the present embodiment, the latch body 31 of the latch portion 3 directly contacts the handle body 21, and the push-pull operation of the handle body 21 of the handle portion 2 in the desired direction is transmitted from the handle body 21 to the latch body 31, thereby rotating the latch body 31. The latch body 31 is locked to the latch receiving portion 4 when the latch body 31 is in a posture inclined with respect to the vertical direction, and the latch body 31 is unlocked from the latch receiving portion 4 when the latch body is in a posture extending in the vertical direction.

Therefore, when the latch body 31 is switched between the state of being locked to the latch receiving portion 4 and the state of not being locked to the latch receiving portion 4, it is not necessary to pivot the latch body 31 greatly, and it is only necessary to perform a small operation of pushing and pulling the handle body 21 in an intended direction.

Thus, the handle body 21 abuts against the latch body 31, and the latch body 31 can be rotated by a small operation of the handle body 21. Therefore, the mechanism for switching the pushing and pulling operation of the handle body 21 in the desired direction and rotating the latch body 31 can be simply configured, and the number of components of the handle device 1 can be reduced to make it compact.

By making the handle device 1 compact, the handle device 1 can be attached to the partition 13 even when the frame 151 of the door 15 is thin, and the appearance of the partition 13 can be improved.

The latch body 31 has an engaged portion 35 provided at a lower end portion and engaged with the latch receiving portion 4, and a handle operation portion 34 provided at an upper end portion and operated to operate the handle portion 2, and the shaft portion 36 is disposed between the engaged portion 35 and the handle operation portion 34, and a distance from the shaft portion 36 to the engaged portion 35 is set to be longer than a distance from the shaft portion 36 to the handle operation portion 34.

With this configuration, even if the operation of the handle operation acting portion 34 is small, the engaged portion 35 can be reliably rotated.

The handle operation portion 34 has a first inclined surface 341 provided on a surface closer to the indoor side 16 in the expected direction of the handle operation portion 34 and a second inclined surface 342 provided on a surface closer to the outdoor side 17 in the expected direction of the handle operation portion 34, and the handle portion 2 has a first latch abutting portion 261 capable of abutting against the first inclined surface 341 and a second latch abutting portion 262 capable of abutting against the second inclined surface 342.

With this configuration, the first latch abutting portion 261 and the second latch abutting portion 262 of the handle portion 2 directly act on the first inclined surface 341 and the second inclined surface 342 of the handle operation acting portion 34. Therefore, the latch portion 3 can be rotated by switching the pushing and pulling operation of the handle portion 2 in the desired direction without using a complicated mechanism.

The embodiment of the handle device 1 of the present invention has been described above, but the present invention is not limited to the above embodiment, and can be appropriately modified within a range not departing from the gist thereof.

For example, in the above embodiment, the latch portion 3 has the engaged portion 35 provided at the lower end portion and engaged with the latch receiving portion 4, and the handle operation portion 34 provided at the upper end portion and operated to operate the handle portion 2, the shaft portion 36 is disposed between the engaged portion 35 and the handle operation portion 34, and the distance from the shaft portion 36 to the engaged portion 35 is set to be longer than the distance from the shaft portion 36 to the handle operation portion 34. In contrast, the position of the shaft portion 36 provided in the latch portion 3 can be set as appropriate.

In the above embodiment, the handle operation portion 34 has the first inclined surface 341 provided on the surface closer to the indoor side 16 in the expected direction and the second inclined surface 342 provided on the surface closer to the outdoor side 17 in the expected direction of the handle operation portion 34, and the handle portion 2 has the first latch abutting portion 261 which can abut against the first inclined surface 341 and the second latch abutting portion 262 which can abut against the second inclined surface 342. In contrast, an inclined surface may be formed only on one surface in the expected direction of the handle operation acting portion 34, and a latch abutting portion abutting against the inclined surface may be provided on the handle portion 2.

The first inclined surface 341 and the second inclined surface 342 may have shapes other than the above-described shapes.

For example, in the above embodiment, the first inclined surface 341 and the second inclined surface 342 are formed over the entire length of the handle operation acting portion 34 (the portion of the latch body 31 located above the shaft portion in the longitudinal direction). In contrast, as in the latch portion 3B of the handle device 1B shown in fig. 12, the first inclined surface 341B and the second inclined surface 342B may be formed only in the vicinity of the upper end portion in the longitudinal direction of the handle operation operating portion 34B, and the portion of the handle operation operating portion 34B that is lower than the first inclined surface 341B and the second inclined surface 342B (the shaft coupling portion 33 side) may not abut against the handle portion 2 (see fig. 4).

Thus, a force applied from the grip portion 2 to the grip operation acting portion 34B can be applied to the vicinity of the upper end portion in the longitudinal direction (the vicinity of the upper end portion, the side apart from the shaft portion 36) of the grip operation acting portion 34B. Therefore, the latch portion 3B can be rotated by a small force from the handle portion 2. Static frictional resistance between the handle portion 2 and the latch portion 3B can be generated, and the operating force can be transmitted from the handle portion 2 to the latch portion 3B at the start of the maximum operating force.

The first inclined surfaces 341, 341B and the second inclined surfaces 342, 342B may be flat inclined surfaces, or may be inclined surfaces whose inclination changes at an intermediate point or curved inclined surfaces.

For example, the rear portion of the first inclined surfaces 341 and 341B and the second inclined surfaces 342 and 342B, which first contacts the handle portion 2, may be an inclined surface having a larger inclination than the front portion, and the inclination may be switched at a middle position in the front-rear direction.

The engaged portion 35 may be other than the above-described one.

For example, as in the latch portion 3B of the handle device 1B shown in fig. 12 to 14, the slide protrusions 353 may be provided at the lower edge portions of both sides of the engaged portion 35B in the expected direction. The slide projection 353 slides on the inner peripheral surface of the opening 371 of the door latch accommodating portion 37. The sliding projection 353 is formed over the entire front-rear direction of the engaged portion 35. When the latch portion 3 is in the latch protruding state, the slide projection 353 receives the rear portion 354 in the opening 371. When the latch portion 3 is in the latch non-protruding state, the slide projection 353 receives the front portion 355 in the opening 371.

The rear portion 354 of the slide projection 353 has a uniform projecting dimension in the front-rear direction, and the front end surface is formed as a flat surface facing the expected direction. On the other hand, the front portion 355 of the slide projection 353 is formed as an inclined surface whose projecting dimension gradually decreases from the rear side to the front side.

The engaged portion 35B is configured such that when the latch portion 3B is in the protruding state, the rear portion 354 of the slide projection 353 abuts against the inner peripheral surface of the opening 371, and when the latch portion 3B is in the non-protruding state, the front portion 355 of the slide projection 353 is separated from the inner peripheral surface of the opening 371. The latch portion 3B is configured to be rotatable when a predetermined force is applied thereto even if the rear portion 354 of the slide projection 353 abuts against the inner peripheral surface of the opening 371.

With this configuration, even if a force in a desired direction acts on the handle operation acting portion 34B of the latch portion 3B from the handle portion 2 when the latch portion 3B is changed from the latch projecting state to the latch non-projecting state, the engaged portion 35B can be prevented from being operated in the desired direction by the force.

When the latch portion 3B is in the protruding state, the rear portion 354 of the slide projection 353 abuts against the inner peripheral surface of the opening 371. Therefore, when the latch portion 3B is in the latch protruding state, the latch portion 3B is not rotated by a force from a portion other than the handle portion 2, and the force can be prevented by a frictional force between the sliding projection 353 and the inner peripheral surface of the opening 371.

In the above embodiment, the latch unit 3 is configured to reliably maintain the latch protruding state in a state where the door 15 closes the opening 12, by the first to fourth magnets 51 to 54. In contrast, the first to fourth magnets 51 to 54 may not be provided, but may be configured to be in a latch protruding state in a state where the door 15 closes the opening 12 by utilizing the shape of the latch portion 3 or the like.

In the above embodiment, the handle device 1 is provided to the hinge door, but may be provided to a sliding door.

In the above embodiment, the latch portion 3 shows an example in which the engaged portion is provided at the upper end portion and the handle operation acting portion is provided at the lower end portion. The latch portion may have the engaged portion provided at a lower end portion and the handle operation portion provided at an upper end portion.

In the above embodiment, the first inclined surface 341 is formed on the surface of the indoor side 16 in the expected direction and the second inclined surface 342 is formed on the surface of the outdoor side 17, but the first inclined surface may be formed on the indoor side and the second inclined surface may be formed on the outdoor side.
