Description

The present invention relates to the structure of doors and sliding doors (hereinafter referred to as “doors”).

When the door is opened and closed, the frame and the door collide with each other to generate noise. In addition, as the opening and closing operation, many noise generations such as turning of the handle, entering and exiting of latch and sickle (hook), entering and exiting of dead bolt, insertion / rotation / pulling of key, rattling due to rattling and stagnation due to lack of oil It is done.
Of these noises, for example, by appropriate lubrication and adjustment, rubbing and squeaking noises are reduced / disappeared, and collisions between the frame and the door during opening and closing use door cushions and cushion packing that is installed on the door frame. Can be greatly reduced.
However, the lock and handle area are mostly made of metal parts due to strength and durability problems, so a certain amount of play space is required. It is prone to harsh sounds. Since the contact sound between metals is in the mid to high range, the sound can be heard even if the volume is low.

  For example, in the case of a door, a lock provided with a latch is used to hold the door frame in a closed state. FIG. 15 is a front view showing the door 100 to which the lock 10 having the latch 14 is attached, and FIG. 16 is a front view of the lock 10 attached to the door 100.

  As shown in FIG. 16, the lock 10 mainly includes a latch drive mechanism (not shown), a case member 11, a latch 14, and a door handle 15. The latch drive mechanism is housed in the case member 11, and the door handle 15 is connected to the latch drive mechanism via the shaft 16. Then, by rotating the door handle 15, the latch 14 is moved back and forth in the left-right direction via the latch drive mechanism. When the door 100 is closed, the latch 14 protrudes from the left end of the door 100 and engages with a latch receiver provided on the door frame. A handle plate 20 that supports the door handle 15 is provided between the door handle 15 and the surface of the door 100.

  In such a lock 10, a “click” sound was always generated when the latch 14 entered the latch receiver. Normally, there is a drawback that even if you don't care about it, for example, when you open and close the door at midnight, it can be heard as a fairly loud sound. Further, the sound of turning the door handle 15 was also a concern.

  In addition, as a lock attached to the sliding door, a hook with which a hook appears and is used is used. FIG. 17 is a front view showing the sliding door 200 to which the lock 30 having the hook 35 is attached, and FIG. 18 is a front view of the lock 30 attached to the sliding door 200. FIG. 18A shows the state of the lock 30 when the sliding door 200 is open, and FIG. 18B shows the state of the lock 30 when the sliding door 200 is closed.

  As shown in FIGS. 18A and 18B, the lock 30 mainly includes a hook drive mechanism (not shown), a case member 31, a slide button 34, and a hook 35. The hook driving mechanism is housed in the case member 31 and connected to the slide button 34 and the hook 35, respectively. When the sliding door 200 is open, the slide button 34 protrudes from the case member 31. When the sliding door 200 is closed and the left end of the sliding door 200 comes into contact with a pillar or a wall, the slide button 34 is pushed into the case member 31, and the hook 35 projects from the case member 31 in conjunction with this. It is like that. At this time, the hook 35 is adapted to be engaged with a striker provided on a pillar or a wall. A pulling handle 40 provided with an operation handle 50 is attached to the surface of the sliding door 200.

  In such a lock 20, a sound when the hook 35 protrudes from the case member 31 and a sound of “click” are always generated when engaged with the striker. Normally, there is a drawback that even if you don't care about it, for example, when you open and close the door at midnight, it can be heard as a fairly loud sound. Further, the sound of operating the operation handle 50 is also a concern.

In order to deal with the above problems, many proposals have been made as follows.
Patent Document 1 describes an invention in which a shock absorbing material is used inside a lock to absorb an impact force at the time of latch movement. Patent Document 2 describes an invention that uses a magnet inside the lock to reduce the collision sound of the latch. Furthermore, Patent Document 3 describes an invention in which a high-viscosity substance is used inside the lock to reduce the collision sound of the latch.
Patent Document 4 describes an invention in which a sound insulating material is provided between a cover plate provided with a through hole and a door.

As shown in FIGS. 5A and 5B, the lock 30 mainly includes a hook drive mechanism (not shown), a case member 31, a slide button 34, and a hook 35. The hook driving mechanism is housed in the case member 31 and connected to the slide button 34 and the hook 35, respectively. When the sliding door 200 is open, the slide button 34 protrudes from the case member 31. When the sliding door 200 is closed and the left end of the sliding door 200 comes into contact with a pillar or a wall, the slide button 34 is pushed into the case member 31, and the hook 35 projects from the case member 31 in conjunction with this. It is like that. At this time, the hook 35 is adapted to be engaged with a striker provided on a pillar or a wall.
The case member 31 is screwed with a screw 32, and the lock 30 is fixed to the sliding door 200 with a mounting plate 33.

On the other hand, the damping material 3 is adhered to the outside of the case member 31. The damping material 3 does not need to be adhered to the case member 31 without a gap, and projections such as screws and shafts may be omitted.
FIG. 6 is a cross-sectional view showing a state where the lock 30 is attached to the sliding door 200.
In the third embodiment, as shown in FIG. 6, the damping material 3 is attached to the front and back surfaces of the case member 31, but only one of them may be attached, or the upper surface, the lower surface, and the side surface may be attached. . Further, it may be attached to the inside of the case member 31 or may be attached to both the outside and inside of the case member 31.

  According to the lock 30 according to the third embodiment, since the vibration damping material 3 is attached to the outside of the case member 31 that houses the hook drive mechanism, the vibration damping material 3 absorbs the vibration caused by the hook 35 protruding and protruding, and noise is generated. Occurrence can be prevented.

Moreover, since it sticks on the outer side of the case member 31, it is not necessary to change the internal structure of the lock | rock 30, and it can apply easily to the existing product. Therefore, by sticking the vibration damping material 3 to a conventional lock that already has a soundproofing effect, a further soundproofing effect is exhibited and a lock close to silence can be obtained.
When sticking to the inside of the case member 31, it may be necessary to change the size of the parts to some extent, but when sticking to the outside, a part of the mounting hole of the sliding door 200 is slightly enlarged. Only renovation is required.

  Next, a sliding door structure according to Embodiment 4 of the present invention will be described with reference to FIGS. The sliding door structure according to Embodiment 4 is obtained by attaching a lock to the sliding door 200, and the appearance thereof is the same as that of FIG.

First, a state when the sliding door 200 is opened will be described with reference to FIGS. 7, 8, 13, and 14. 8 is a cross-sectional view taken along the line DD of FIG.
As shown in FIGS. 7 and 8, a lock 30 is attached to the sliding door 200 that moves in the left-right direction. When the sliding door 200 is open, the slide button 34 protrudes from the case member 31. Further, a slide plate 36 projects rightward from the right side surface of the case member 31 (the side opposite to the projecting surface of the slide button 34). As will be described later, the slide plate 36 is interlocked with the movement of the hook 36.

On the other hand, a pulling handle 40 is attached to the front and back surfaces of the sliding door 200, and the sliding door 200 can be moved left and right by hooking the hand on the pulling handle 40. The puller 40 is embedded in the front and back surfaces of the sliding door 200 and is formed of a rectangular plate material having a substantially U-shaped cross section so that the hand can be hooked in the recess. An operation handle 50 is attached to the puller 40 via a shaft 53. When the sliding door 200 is moved in the right direction (opening direction), a hand is put on the operation handle 50 to rotate the operation handle 50 about the shaft 53.
In addition, in Embodiment 4, it is set as the structure which attached the handle 40 to the front and back both surfaces of the sliding door 200, However Of course, the structure attached only to either one surface may be sufficient.

As shown in FIG. 13, the puller 40 is provided with an opening 41 through which a contact portion 51 of an operation handle 50, which will be described later, can pass, and the damping material 4 is attached to the back surface. The damping material 4 does not need to be stuck to the back surface of the puller 40 without any gap, and the protruding portions such as the screws 42 may be omitted.
As shown in FIG. 14, the operation handle 50 includes a substantially half-moon shaped main body 52 bent in a substantially L-shaped cross section, and a contact portion 51 provided at the center of the side end of the main body 52. The damping material 5 is attached to the front and back surfaces of the contact portion 51. Note that the vibration damping material 5 may be attached to either the front or back surface of the contact portion 51.
Further, either one of the vibration damping material 4 and the vibration damping material 5 may be used, but it is more effective to use both.

Next, with reference to FIG.9 and FIG.10, the state when the sliding door 200 is closed is demonstrated. 10 is a cross-sectional view taken along the line DD of FIG.
As shown in FIGS. 9 and 10, when the sliding door 200 is closed, the left end portion of the sliding door 200 abuts against a pillar, a wall, etc., and the slide button 34 is pushed into the case member 31 and interlocked therewith. The hook 35 protrudes leftward from the case member 31. The hook 35 is engaged with a striker provided on a pillar or wall.
Further, in conjunction with the protrusion of the hook 35 in the left direction, the slide plate 36 that protrudes from the right side surface of the case member 31 further protrudes in the right direction to the position immediately before the contact with the contact portion 51 of the operation handle 50. Has moved.

Next, with reference to FIG.11 and FIG.12, the movement when opening the sliding door 200 is demonstrated. 12 is a cross-sectional view taken along the line DD of FIG.
As shown in FIGS. 11 and 12, when the sliding door 200 is opened, the hand is hooked on the operation handle 50 of the pulling hand 40 in order to move the sliding door 200 in the opening direction (right direction). At this time, the operation handle 50 rotates around the shaft 53. In accordance with this rotational movement, the contact portion 51 of the operation handle 50 pushes back the slide plate 36 that protrudes when the sliding door 200 is closed into the case member 31. As a result, the hook 35 enters the case member 31 in conjunction with the movement of the slide plate 36, disengages from the striker provided on the pillar or wall, and can be moved in the direction to open the sliding door 200.

According to the sliding door structure according to the fourth embodiment, since the vibration damping material 4 is attached to the back surface of the pull handle 40 having the operation handle 50, the vibration damping material 4 absorbs vibration when the operation handle 50 is operated. Noise generation can be prevented.
Further, the lock 30 is provided with a slide plate 36 that is interlocked with the movement of the hook 35, and the operation handle 50 is provided with an abutment portion 51 that abuts the slide plate 36 during operation and allows the hook 35 to be immersed. Since the damping material 5 is attached to the contact portion 51, the vibration control material 5 absorbs vibration when the operation handle 50 is operated and the contact portion 51 comes into contact, thereby preventing noise generation. Can do.

In particular, the portion of the sliding door 200 to which the lock 30 and the pulling handle 40 are attached has through-holes on the left end, front surface, and rear surface of the sliding door 200, and noise is likely to fall out of the cylinder. The sticking of the material 5 is very effective.
Further, the attachment of the vibration damping material 3 to the lock 30 in the third embodiment and the attachment of the vibration damping material 4 to the back surface of the handle 40 and the vibration damping material 5 to the contact portion 51 in the fourth embodiment are combined. Then, there is a soundproofing effect for a wide range of sounds generated from the lock part, and furthermore, since it can be used in combination with a conventional lock that already has a soundproofing effect, a very advanced soundproofing process is possible.

The noise prevention effect in the first to fourth embodiments is that the vibration damping material is converted into heat energy by absorbing the vibration energy generated when the metal and the metal are in contact with each other by sticking the vibration damping material. This is what happens.
Moreover, since only the damping material is stuck, a complicated structure is not required and the cost is not increased. Furthermore, since the damping material is only attached, there is very little movement that absorbs vibration, and there is little wear and aging.

  In addition, the above-described noise prevention effect is that vibration is absorbed and attenuated by the action of the damping material, centering on an annoying medium to high frequency sound such as “kachikacha” among the noise generated by contact between metals. As a result, the sound that is generated is such that there is an unpleasant sound, such as a low-to-midrange centered sound, for example, the feeling that the high-heeled walking sound has changed to the walking sound of rubber-bottomed athletic shoes Become. It can be said that these sound quality is small but the sound is profound and the luxury of doors and the like is increased.

  Moreover, in the said embodiment, you may apply a damping paint instead of sticking a damping material. If it is a damping paint, it can respond also to a place with unevenness or a place where it is hard to stick a damping material, such as a curved place.

  Moreover, in the said embodiment, instead of sticking the damping materials 1-5 to the case members 11 and 31, the handle plate 20, the handle 40, and the contact part 51, these are damped between two metal plates. You may comprise the damping steel plate which narrowed the material. In the case of a damping steel plate, the steel plate has a damping structure in advance and can be manufactured in almost the same process as before.
