TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sickle lock for a sliding door.
[0002]
[Prior art]
As a conventional sliding door sickle lock, the sliding door 38 was once completely closed, and then the sickle member 2 having the engaging portion 7 interlocked with the operation knob was rotated and attached to the frame 37. The mainstream configuration is such that the engaging portion 7 is protruded and retracted in a plate-shaped receiver c having a square hole at the center portion to lock and unlock. However, in the above configuration, the locking / unlocking operation is always manual, and it is necessary to perform the locking / unlocking as a separate operation after closing the sliding door 38, and to perform the locking operation by mistake with the sliding door 38 opened. If the engaging portion 7 of the sickle member 2 is protruded, and the sliding door 38 is closed as it is, there is a problem that the tip of the engaging portion 7 collides with the front of the receiver c and is broken. Therefore, a trigger mechanism for preventing a malfunction as disclosed in Japanese Utility Model Laid-Open No. 5-47263, which prevents the operation knob from moving when the sliding door 38 is open, or the engaging portion 7 is protruded. Even if the sliding door 38 is closed and collides with the front of the receiving member c from the malfunctioning state, it is necessary to add another mechanism so that the entire sickle member 2 is retracted and returns to the release position without being damaged. However, even if this malfunction prevention mechanism is added, the operation becomes possible when the trigger is pressed, so that it is not yet complete.
[0003]
Therefore, as a different idea, not from the viewpoint of preventing malfunction, the trigger protruding from the front of the sliding door 38 and the sickle member 2 are connected, and only the trigger protrudes from the front of the door when the sliding door 38 is open. At this time, the engaging portion 7 of the sickle member 2 is in a state of being submerged in the case 1, and the trigger is in contact with the front of the receiver c and is submerged, and at the same time, the sickle member 2 is rotated and the engaging portion 7 is projected. Japanese Unexamined Patent Publication No. 8-86132 discloses a configuration in which the trigger insertion / retraction operation at the final stage of closing the sliding door 38 inserted into the receiver c is converted into the rotation operation of the sickle member 2 to engage the receiver c with the engaging portion 7. Many are disclosed in, for example, JP-A-10-28069.
[0004]
In addition, as a result of improving the running performance of the sliding door 38 so that even elderly people or children with weak power can open and close with a light force, a phenomenon that the sliding door 38 largely rebounds when the door is suddenly closed has recently become a problem. In the former configuration in which the sickle member 2 is manually rotated to lock and unlock, it is naturally impossible to prevent rebound, and in the latter configuration in which the trigger and the sickle member 2 are interlocked, the sliding door 38 is closed. In this state, the trigger is pushed and the engaging portion 7 of the sickle member 2 is temporarily engaged with the catch c. However, when the sliding door 38 is opened, the sickle member 2 rotates in the unlocking direction and the trigger protrudes. It can be opened from the state as it is, and it will not be possible to prevent bounce again.
[0005]
In view of the above, a mechanism for further preventing rebound is added to the latter configuration, and the rotation of the sickle member 2 in the unlocking direction is restricted only at the moment when the sliding door 38 is closed and for a certain period thereafter, and then rebound. A number of mechanisms including a mechanism for preventing the problem and returning naturally to a state that can be opened as it is after a certain time have already been disclosed in Japanese Patent Application Laid-Open Nos. 10-292693, 2001-12126, and 2002-138747.
[0006]
Further, instead of adding a rebound preventing mechanism to the configuration in which the trigger is linked with the sickle member 2, the sickle member 2 shown in FIG. The spring member 4 is urged so that the engaging portion 7 of the sickle member 2 always projects from the front surface 14 of the case, and an inclined surface 8 is formed at the tip of the engaging portion 7. At the final stage when the sliding door 38 is closed, the inclined surface 8 comes into contact with the upper end 26 of the square hole 24 for inserting the engaging portion of the receiving part c, and the sickle member 2 rotates along the inclination against the bias of the spring member 4. Then, there is an automatic lock mechanism in which the sickle member 2 is returned to the locking direction by the spring member 4 and becomes engaged when the engaging portion 7 has passed over the front of the receiver c. The mechanism itself has been often used for various purposes, and it does not require not only triggers but also parts such as springs for the triggering operation, so the number of parts is small, and the lock state is always maintained. Therefore, it is also possible to prevent rebound.
[0007]
However, in the automatic lock mechanism as described above, the unlocking operation is usually required every time the sliding door 38 is opened, and the operability is very poor. Therefore, as shown in FIG. 15A, the handle 5 is assembled to the sickle member 2, and the sickle member 2 is configured to rotate in only one direction about the rotation shaft 3 in conjunction with the handle 5, As shown in FIG. 5B, there is a configuration in which the unlocking operation can be performed simultaneously with the rotating operation of the handle 5 and the sliding door 38 can be opened by pulling the handle 5 as it is after unlocking. Also, the unlocking operation with the handle 5 is a rotating operation on a plane parallel to the sliding door 38, and the direction is different from the left-right operation of opening and closing the sliding door 38, and the operability is not so good.
[0008]
The biggest problem with this automatic locking mechanism is that when the sliding door 38 is open, the entire engaging portion 7 of the sickle member 2 which is much larger than the trigger always projects from the door tip surface, and the maximum opening The automatic locking mechanism is often used for sliding doors 38 used in houses, etc., because the dimensions of the doors are reduced, and the projections become large projections when passing. Not yet.

[Problems to be solved by the invention]
However, in the configuration in which the operation in which the trigger abuts on the receiving surface at the final stage of closing the sliding door described above is converted into the rotation operation of the sickle member, components such as the trigger itself and a spring for extending and retracting the trigger are required. As a problem, the number of parts increases and the assembling time is required. Also, when the sliding door is open, the trigger is always protruding from the front of the door, so even if it is a small trigger, it is possible that it will catch clothes when passing and it is still an obstacle. .
[0010]
Further, the mechanism for interlocking the trigger and the sickle member cannot hold the sliding door in the closed state as described above, and cannot prevent rebound from sudden closing. Therefore, even if it is further developed to a structure having a mechanism for preventing rebound, for that purpose, more and more parts are additionally required, and as a matter of course, assembling becomes complicated, the whole size becomes large, and the cost becomes expensive. Conceivable.
[0011]
More recently, it has been pointed out that, in addition to preventing bouncing off, when the construction is poor, the sliding door gradually opens from a closed state due to the inclination or vibration of the rail, etc. Cannot deal with this problem at all. Here, the above-mentioned automatic lock mechanism can solve this problem because the locked state is always maintained.However, in order to use the automatic lock mechanism, the engagement portion of the sickle member with the sliding door opened is always on the traffic side. It is necessary to eliminate the problem of protruding.
[0012]
The present invention has been made in order to solve the above-described problems, and does not require a trigger or a peripheral component for interlocking the sickle member, and further does not require any additional component for a rebound prevention mechanism, and the sliding door is opened. In the unlocked state, the entire sickle member, including the engaging part, is completely stored in the case.Therefore, when the sliding door is open, there is nothing protruding from the door surface to the opening side, providing excellent safety when passing. The operability can be improved by setting the direction of opening and closing the sliding door and the direction of the handle operation for locking and unlocking in the same direction, and a partly automatic lock mechanism is configured so that the sickle member is directly linked with the handle operation Incorporates a small number of components that can reliably prevent bouncing even in the event of a sudden closure, and prevent malfunctions that gradually open due to rail tilt or vibration. An object of the present invention is to provide a sickle lock for the ability of sliding door.
[0013]
[Means for Solving the Problems]
In the present invention, the following technical measures have been taken to achieve the above object. First, a case, a sickle member, and a rotating shaft are provided, and the sickle member is rotatably mounted on the rotating shaft in the case to form a sickle lock body. I do. The vertical frame of the frame has a plate-shaped central hole at the position facing the door surface of the vertical frame, and a receiving hole having an upper and lower inner surface as an engaging surface. The case of the sickle lock is box-shaped and has a flange with mounting holes at the top and bottom of the front face, a square hole for engaging part is provided at the center part of the front of the case, and a rotating shaft insertion hole and an interlocking part are inserted on the side of the case Square holes are provided. The sickle member has a rotation shaft insertion hole, an engagement portion, a first claw, and a second claw.A slope is provided at the tip of the engagement portion, and a locking side is provided on the opposite side. The space between the second claws is formed as a concave portion separated by a certain distance, and the first and second claws have a certain thickness.
[0014]
Next, the sickle member is arranged in the case such that the engagement portion is on the front side of the case, and the sickle member is attached to the rotation shaft in a state where the sickle member can be rotated only within a certain angle range. This fixed angle is set from the position where the engagement part is completely stored in the case to the position where it protrudes greatly to the front of the case and the locking side becomes vertical and vertical, and the former position is the storage state of the sickle member The latter position is set as the protruding state of the sickle member. Further, the square hole for interlocking part insertion on the side surface of the case is arranged at a position where the concave portion is moved by the rotation of the sickle member. Further, a spring member is mounted so that the sickle member is biased in both directions around a middle position in the rotatable range. Therefore, the sickle member is separately biased between the housed state and the projected state, and is stably held at either position, and does not stop during rotation.
[0015]
Also, when the sliding door is closed after the sickle member is in the protruding state, the inclined surface at the tip of the engaging portion is brought into contact with the upper end or the lower end of the square hole for inserting the engaging portion of the receiver mounted on the frame. Set the vertical position of the sickle lock and receiver. Here, there is no limitation on the rotation direction of the sickle member. If the rotatable direction of the sickle member from the protruding state is upward, the direction of the inclined surface at the tip of the engaging portion is obliquely downward from the tip, and the engaging portion of the receiving portion Both are arranged so as to contact the lower end of the insertion square hole, and if the rotatable direction of the sickle member is downward, the direction of the inclined surface at the tip of the engaging portion is obliquely upward from the tip, and the engagement of the receiver Both are arranged so as to contact the upper end of the partial insertion square hole.
[0016]
Next, a handle having an interlocking part is assembled to the seat to form an operation unit main body, and furthermore, the operation unit main body is arranged on both sides of the sliding door, and a sickle lock body attached in a state dug into the door end surface. Fix the sliding door so that the thickness of the sliding door is sandwiched between the seats on both sides. At this time, it is set so that the tip of the interlocking portion is inserted into the recess between the first and second claws through the interlocking portion insertion square hole on the side surface of the case. In addition, it is configured such that the interlocking portion moves in the left-right direction within a certain range by moving the handle with respect to the seat. Therefore, the interlocking portion moves left and right within the concave portion by the operation of the handle, and as a result, the interlocking portion presses the first claw and the second claw, and this operation moves the sickle member in both directions around the rotation axis. It becomes an operation of rotating, that is, it is possible to convert the operation of the handle into an operation of protruding and retracting the engagement portion. When the interlocking part presses the first claw and the second claw, the direction of movement of the handle is opposite to the left and right, and the direction of rotation of the sickle member is also opposite.
[0017]
Here, the rotation direction when the engagement portion shifts from the protruding state to the storage state and the direction in which the interlocking portion moves to obtain the operation are defined as the unlocking direction, and the opposite direction is defined as the locking direction. Further, the claw on the side that rotates the sickle member in the unlocking direction by the lateral movement of the interlocking portion is the first claw, and the claw on the side that rotates the sickle member in the locking direction is the second claw. The first claw side is defined as a first side surface, and the second claw side is defined as a second side surface, on both side surfaces of the interlocking portion.
[0018]
Further, the position of the interlocking portion when the interlocking portion is moved most in the unlocking direction by operating the handle is set as the unlocking side position, and at this time, the first claw of the sickle member is attached to the first side surface of the interlocking portion, and the second claw is provided. Are in contact with the second side surface, and are set so that both side surfaces of the interlocking portion are sandwiched between both claws. Therefore, when the sliding door is normally opened, the handle is held in the above state, and the sickle member is in the housed state.
[0019]
When the handle is operated in the direction to close the sliding door from this state, the interlocking portion moves in the locking direction before the sliding door starts running, and the second side surface of the interlocking portion pushes the second claw against the bias of the spring member. Then, the sickle member rotates and the engaging portion starts to protrude. Here, when the sickle member rotates to some extent and crosses the position of the boundary, and the direction urged by the spring member changes, the sickle member changes to an operation in which the sickle member first attempts to rotate to a protruding state by the force of the spring member. The pushing of the second claw on the second side surface of the interlocking portion by operating the handle is limited to a position immediately after the biasing direction of the spring member is changed to the locking direction, and the interlocking portion is most in the locking direction. Assuming that the position during the movement to the lock position is the lock position, the left and right movement of the interlocking portion is limited to the range from the unlock position to the lock position.
[0020]
Therefore, after the second side surface of the interlocking portion pushes the second claw to the locking position, the sickle member further rotates and moves to the protruding state only by the force of the spring member. The sides are set to be separated by a certain distance. As a result, the sickle member is rotatable against the bias of the spring member in the unlocking direction at the angle from the protruding state to the second claw abutting on the second side surface, with the interlocking part holding the locking position. Assuming that this angle is a free angle, the sickle member does not interlock with the operation of the handle only by the free angle in the unlocking direction from the projected state.
[0021]
The handle has already stopped when the interlocking part has reached the locking position, the sickle member is in a protruding state, and when the sliding door is closed by a series of operations with the handle, immediately before it is completely closed In this case, the inclined surface at the tip of the engaging portion comes into contact with either the upper end or the lower end of the square hole for inserting the engaging portion of the receiver. Here, as described above, the sickle member is rotatable by a free angle in the unlocking direction, and is pushed by the inclined surface so that the engaging portion gets over the end of the engaging portion insertion square hole. After that, when the engaging portion is completely inserted into the receiving portion, the sickle member is rotated again by the force of the spring member in the locking direction until the sickle member protrudes, and the engaging surface of the receiving portion is engaged with the locking side of the engaging portion. And the sliding door can be locked. The operation at this stage is the same as that of the automatic lock mechanism described above, and it is important that the rotation angle necessary for the tip of the engaging portion to get over the front of the receiver is set smaller than the free angle. It is preferable to set the position of the boundary so that the biasing direction of the spring member does not change due to the rotation of the sickle member in the unlocking direction in the inside.
[0022]
Next, during the operation in which the interlocking part moves from the unlocking side position to the locking side position, the first claw once separates from the first side surface of the interlocking part, and after the interlocking part stops at the locking side position, only the spring member The first claw is set so as to be in contact with the first side surface of the interlocking portion again when the sickle member comes into a protruding state by force. By setting in this way, when the interlocking part is moved in the unlocking direction by operating the handle from the locked state in which the sliding door is closed, the first side immediately pushes the first claw to rotate the sickle member in the unlocking direction. Operation is obtained, and the engaging part is disengaged from the receiving part and the sliding door can be opened.
[0023]
As the operation in the unlocking direction at this time, the first side of the interlocking portion keeps pushing the first claw until it moves to the unlocking side position, the biasing direction of the spring member changes midway, and the interlocking portion unlocks. At the same time when the sickle member is moved to the side position, the sickle member returns to the stowed state, and the second claw also returns to the state in which it comes into contact with the second side surface again, and is held at this position by the force of the spring member. The operation of the handle has already stopped at this unlocking position, and thereafter the sliding door can be opened by a series of operations in the same direction while holding the handle.
[0024]
The mechanism of the operation unit body and the method of operating the handle for obtaining the above-described left and right movement of the interlocking portion may be of any configuration, but a slide in which the handle moves left and right in the same direction as the interlocking portion in the seat. The movement and the swinging movement, in which the handle rotates around a vertical axis on a plane parallel to the sliding door provided on the seat, are simple and suitable.In the latter case, the direction of movement of the interlocking part in response to the left and right operation of the handle It is preferable that the positions of the first and second claws are reversed left and right.
[0025]
Further, as described above, when the setting is made so that the sickle member rotates in the unlocking direction by operating the handle in the direction to open the sliding door, and the sickle member rotates in the locking direction by operating the handle in the direction to close the sliding door. The operation of pushing and pulling the handle left and right to open and close the door and the operation of locking and unlocking can be performed as a series of operations. To summarize the entire operation, first, pull the handle to open the sliding door from the locked state where the engaging part is engaged with the receiver, and at the same time, the engaging part separates from the receiver and the sickle member is stored as it is After that, the sliding door can be completely opened by a series of operations while holding the handle. Conversely, if you operate the handle in the closing direction to close the sliding door, the interlocking part will immediately move to the locking side position and the sickle member will protrude faster than the sliding door runs, and then the handle will be held The sliding door can be closed by a series of operations, and in the final stage of complete closing, the inclined surface of the engaging part abuts the end of the square hole for inserting the engaging part of the receiver, over the front of the receiver, and by the automatic lock mechanism It will be lockable.
[0026]
With the above-described configuration, in the locked state, the engagement portion is completely engaged with the receiving portion, so that it is possible to completely prevent the spring from rebounding, and the poorly-installed rail is inclined or constantly vibrated. The phenomenon that the sliding door opens on its own can be prevented even under the condition of receiving. Here, as described above, in the present invention, it is possible to always prevent the rebound, so it is important to reduce the impact of the rebound at the time of sudden closing. Therefore, by providing a contact member with strong elasticity at the engagement side position of the engagement part and adding a configuration to reduce the impact and sound at the time of rebound, it is possible to develop a more excellent rebound prevention mechanism. it can.
[0027]
In addition, the receiver is composed of two inner and outer box-shaped members, the inner member is provided with an engaging portion insertion square hole and an engaging surface, and a strong winding spring is inserted between the two in a state of being overlapped When doing so, when the rebound load is applied to the engaging surface, the inner member will move in the direction of rebound, and at this time, the impact of the rebound can be absorbed by the compression force of the winding spring, It is possible to propose a more effective bounce prevention mechanism.
[0028]
Therefore, according to the present invention, when the sliding door is opened, the entire sickle member including the engaging portion is held in a state of being completely housed in the case, and there is no need for a trigger or any other parts for preventing rebound, and the door end side is not required. Since there is nothing protruding from the road, safety during traffic is improved. In addition, the door can be locked and unlocked only by the normal opening and closing operation of pushing and pulling the sliding door to the left and right, so it is excellent in operability, it can prevent rebounding when suddenly closing, and it has a very small number of parts This is advantageous in terms of cost.

Then, the sickle member 2 is urged to either the protruding state or the stored state with the middle position in the rotatable range of the sickle member 2 regulated between FIGS. 5 (a) to 5 (d) as a boundary. The spring member 4 is arranged in such a manner as to be performed. Therefore, the shape of the spring member 4 is excellent in a coil spring as shown in FIG. 5, and is set so that a force is always applied in a direction in which both ends spread, and both ends are attached to the case 1 and the sickle member 2. When the position shown in FIG. 5B is to be set as a boundary position for urging in both directions, one end position of the spring member 4 attached to the sickle member 2 in the state of FIG. The spring member 4 is most compressed at this position, and the sickle member 2 is located at this position. It can be biased by being divided into a stored state and a projected state. Therefore, the sickle member 2 is stably held at the retracted position where the sickle member 2 is rotated to the maximum in both directions and the projected position.
[0041]
The shape of the spring member 4 only needs to be set so that the biasing direction can be changed at an arbitrary position on the way with respect to the rotatable range of the sickle member 2, and although not shown, a coil spring as shown in FIG. Instead, a configuration may be adopted in which a polygonal member is disposed coaxially with the rotation shaft 3 and the polygonal member is sandwiched between leaf springs and embraced from both sides. In this case, the polygonal member protrudes. It can be biased in both directions at the corner position.
[0042]
Next, the rotation operation of the sickle member 2 accompanying the movement of the interlocking portion 19 to the door tip side by operating the handle 5 from the state shown in FIG. When the interlocking portion 19 moves in the locking direction from the unlocked state of FIG. 5A, the second side surface 21 of the interlocking portion 19 pushes the second claw 11, and the sickle member 2 rotates in the locking direction while the engaging portion 7 is rotated. Begins to protrude. The state shown in FIG. 5B is the position of the boundary of the biasing direction of the spring member 4, and up to this point, the handle 5 and the interlocking portion 19 are operated to move against the spring member 4. In the state of FIG. 5B, the interlocking portion 19 can still be moved to the door end side. In the operation after FIG. 5B, the second claw 11 is further pushed by the interlocking portion 19 and the spring member 4 is simultaneously moved. Since the position exceeds the boundary, the sickle member 2 is rotated in the locking direction by being pushed by both the interlocking portion 19 and the spring member 4.
[0043]
Here, as the next stage, the position shown in FIG. 5C is important, and this position is a state where the interlocking portion 19 has reached the locking side position which is the most door-side, and the position is interlocked with the handle 5 at this position. The operation of part 19 will stop. Therefore, the operation of the second side surface 21 of the interlocking portion 19 pressing the second claw 11 of the sickle member 2 is up to the state of FIG. 5C, and the sickle member 2 is still completely completed only by the operation of being pressed by the interlocking portion 19. Is set so as not to reach the protruding state. After the position shown in FIG. 5C, the sickle member 2 is further rotated to the protruding state shown in FIG. That is, the rotation of the sickle member 2 in the range of FIGS. 5C to 5D is not interfered with the interlocking portion 19, and only the force by the bias of the spring member 4 acts. The angle at which the rotation of the sickle member 2 is allowed is defined as a free angle. As an actual operation, the rotation of the sickle member 2 due to the bias of the spring member 4 is faster, and the position in FIG. 5C is merely a mere passing point, and the sickle member 2 is drawn from FIG. It is considered that the operation moves to 5 (d).
[0044]
Also, by changing the distance from the rotation shaft 3 to the contact point between the first claw 10 and the first side surface 20 and the distance from the rotation shaft 3 to the contact point between the second claw 11 and the second side surface 21. When the interlocking portion 19 is moved from a state where both claws shown in FIG. 5A are in contact with both side surfaces of the interlocking portion 19, the second claw 11 is always in contact with the second side surface 21 until FIG. , The trajectory of the first nail 10 and the second nail 11 can be obtained such that the first nail 10 gradually moves away from the first side surface 20. Then, further rotation of the sickle member 2 after the interlocking portion 19 after FIG. 5C stops, the first claw 10 approaches the first side face 20 at a stretch, and the sickle member 2 of FIG. The first claw 10 is set so as to be in contact with the first side surface 20 again at the position rotated to the protruding state.
[0045]
A series of operations described above are operations when the sliding door 38 is about to be closed from a widely opened state, and the sliding door 38 is closed from the state of FIG. 5A in which the handle 5 is held at the unlocking position. When the handle 5 is operated in the direction, the interlocking portion 19 moves to the locking side position in FIG. 5C earlier than the sliding door 38 starts traveling, and the sickle member 2 is moved by the spring member 4 almost simultaneously as shown in FIG. Will rotate to the projected state. Thereafter, since the handle 5 stops at the locking position, the sliding door 38 can be closed by a series of operations of pulling the handle 5 in the same direction.
[0046]
Next, an operation of engaging the engaging portion 7 with the receiving part c at the final stage of closing the sliding door 38 following the above operation will be described with reference to FIG. FIG. 6A shows the same state as FIG. 5D, in which the inclined surface 8 at the tip of the engaging portion 7 of the sickle member 2 is close to the upper end portion 26 of the square hole 24 for inserting the engaging portion of the receiver c. When the sliding door 38 is further closed, the inclined surface 8 of the engaging portion 7 comes into contact with the upper end portion 26 of the square hole 24 for inserting the engaging portion. As a result, as shown in FIG. 6B, the sickle member 2 rotates in the unlocking direction. At this time, the sickle member 2 is interfered with the position of the handle 5 and the interlocking portion 19 by the aforementioned free angle. If the above-mentioned free angle is set to be larger than the rotation angle required for the engaging portion 7 to climb over the upper end portion 26 of the receiver c, the engaging portion 7 can be rotated as shown in FIG. Can be rotated up to the position.
[0047]
If the spring member 4 does not exceed the boundary at the position shown in FIG. 6C and the sickle member 2 is set to be urged in the direction of returning to the protruding state, the engagement portion 7 is formed. At the stage where the sickle member 2 is completely inserted into the receiver c after getting over the front of the receiver c, the sickle member 2 returns to the protruding state by the force of the spring member 4 as shown in FIG. It becomes possible to lock the side 9 by engaging the engagement surface 25 of the receiver.
[0048]
The operation described with reference to FIG. 6 is exactly the same as that of the conventional automatic lock mechanism. At the moment when the sliding door 38 is completely closed, the locking side 9 of the engaging portion 7 engages with the engaging surface 25 of the receiving c. Therefore, it is possible to surely prevent rebound and maintain the engaged state as it is, so that it will open freely even in situations where the construction is bad and the rail is inclined or it is constantly subject to vibration The phenomenon can also be prevented. The operation of the handle 5 at the initial stage of closing the sliding door 38 described with reference to FIG. 5 causes the engaging portion 7 to be in a protruding state, and further enables the locking by the continuous closing operation of the sliding door described with reference to FIG. Therefore, a conventional trigger for preventing malfunction when the sliding door 38 is opened, a trigger for interlocking to rotate the sickle member 2 and insert it into the receiving c at the final stage of closing the sliding door 38, etc. unnecessary.
[0049]
Next, the operation when the sliding door 38 is opened from the locked state of FIG. 6D will be described with reference to FIG. FIG. 7A shows the same locked state as FIG. 6D, in which the first claw 10 is in contact with the first side surface 20 of the interlocking portion 19. In this state, when the handle 5 is operated toward the door end, which is the direction in which the sliding door is opened, the first side surface 20 of the interlocking portion 19 is turned against the force of the spring member 4 as shown in FIG. , The sickle member 2 is rotated in the unlocking direction, and the engaging portion 7 is disengaged from the engaging surface 25 of the receiver c to unlock.
[0050]
After that, when the biasing direction of the spring member 4 shown in FIG. 7C is changed, the sickle member 2 is brought into the storage state shown in FIG. Will rotate up to. In addition, in the state of FIG. 7D, the interlocking portion 19 reaches the unlocking position, and the handle 5 stops at this position, so that the sliding door 38 can be further opened by a series of operations as it is. In other words, only by operating the handle 5 in the direction in which the sliding door 38 is opened, unlocking and the operation of opening the sliding door 38 can be obtained simultaneously. In the state shown in FIG. 7D, both the first claw 10 and the second claw 11 of the sickle member 2 are in a housed state in contact with the first side surface 20 and the second side surface 21, and as shown in FIG. You can see it is back.
[0051]
The above-described series of operations is a one-cycle operation from the state in which the sliding door 38 is widely opened to the state in which the sliding door 38 is once completely closed to the locked state, and then opened again. When the handle 5 is operated left and right while the sliding door 38 is open, there is no engagement operation between the engagement portion 7 and the receiving member c described in FIG. 6, and the engagement between the sickle member 2 described in FIGS. The operation is such that the joint 7 repeats the appearance.
[0052]
In the first embodiment, as shown in FIG. 4, the operation unit main body b is mounted in a state dug on both sides of the sliding door, and is suitable for an entrance sliding door that enables operation from inside and outside the room and a sliding door for indoor partition. Although the configuration has been described, a configuration suitable for a sliding door such as a cabinet or storage furniture will now be described with reference to FIG. 8 as a second embodiment. Also in the second embodiment, as shown in FIG. 8, the configuration of the sickle lock main body a and the receiving c, the operation of the interlocking portion 19 of the sickle lock main body a and the operation of the sickle member 2, and the like are completely the same as those in the first embodiment. However, in the sliding door 38 of the second embodiment, there is no possibility of a person passing therethrough, so that the operation surface can be limited to one side, and the operation unit main body b only needs to be arranged on one side of the sliding door 38. Become. Therefore, the thickness of the portion of the first claw 10 and the second claw 11 may be thin, and the sickle tablet main body a can be made extremely thin and compact.
[0053]
Furthermore, also in the second embodiment, since the automatic lock mechanism that locks the door at the same time as closing the sliding door is the same, the sliding window of a small boat or the like swinging in the waves, or the side sliding door of a traveling vehicle such as an insulated car etc. It is suitable and can prevent the danger that the sliding door 38 moves suddenly when the vehicle is suddenly stopped in a situation where the locking is forgotten, and furthermore, it is possible to reduce the trouble of locking as a separate operation every time after the opening and closing operation of the sliding door 38. Will be possible.
[0054]
In the first embodiment and the second embodiment, the operating portion main body b is dug in the thickness direction of the sliding door 38 so that the handle 5 and the seat 6 hardly protrude from the sliding door 38 surface. However, this configuration inevitably requires a fingertip to be inserted into the concave portion of the seat 6 and operated left and right like a conventional digging puller, and it is still insufficient in terms of operability. Can be Recently, more operability has been emphasized, and in order to realize more easy opening and closing, a type in which a large pipe-shaped handle 5 is mounted so as to protrude from the surface of the sliding door 38 to some extent, and the handle 5 is gripped, has been increasing. This type is often a one-sided type, and is frequently used for a Western-style sliding door for entrance and a sliding door used in a corridor of a public facility. Therefore, next, as a third embodiment, a configuration applicable to the type using the large handle 5 as described above will be described with reference to FIGS.
[0055]
FIG. 9 is a perspective view of the third embodiment, FIG. 10 is a cross-sectional view showing the operation, and FIG. 11 is a schematic view showing the operation of the interlocking portion 19 and the sickle member 2. The configuration is almost the same as the first embodiment. Here, the first embodiment differs from the first embodiment in that the moving operation of the handle 5 attached to the seat 6 as shown in FIG. 10 is constituted by a swing operation of rotating around a vertical axis parallel to the sliding door 38 surface. Is different. Therefore, the grip portion 29 and the interlocking portion 19 of the handle 5 do not perform a complete right-and-left linear motion, but move substantially on an arc centered on a connecting pin 28 for rotatably assembling the handle 5 to the seat 6. become. Therefore, the maximum swing angle of the handle 5 and the interlocking portion 19 and the interlocking motion so that the interlocking portion 19 moves while contacting the first claw 10 and the second claw 11 and further rotates the sickle member 2 smoothly. The shape of the portion 19 needs to be set.
[0056]
In the third embodiment, since the direction of the left and right movement of the grip portion 29 of the handle 5 and the direction of the left and right movement of the interlocking portion 19 are reversed, the arrangement of the first claw 10 and the second claw 11 of the sickle member 2 is changed. It needs to be reversed. Also in the third embodiment, there is no limitation on the rotation direction of the sickle member 2 as in the first embodiment, and in FIGS. 9 and 11, the rotation of the sickle member 2 in the unlocking direction is the same as the direction described in the first embodiment. 3 is set in the clockwise direction, which is the same direction as in FIG. 3, and the inclined surface 8 at the tip of the engaging portion 7 is formed so as to be inclined obliquely downward from the tip. The structure described below is in contact with the lower end 27 of the square hole 24 for insertion of the engaging portion c.
[0057]
As described above, since the operation of the handle 5 is a swing operation in the third embodiment, the swing angle of the handle 5 and the interlocking interlocking portion 19 is preferably as small as possible as shown in FIG. The longer the distance from the position of the connecting pin 28, which is the center, to the grip portion 29, and the greater the distance from the position of the connecting pin 28 to the contact points between the side surfaces of the interlocking portion 19 and the first claw 10 and the second claw 11, both are larger. It will be excellent in terms of conditions. Therefore, it is preferable that the seat 6 be provided externally without being dug into the surface of the sliding door 38 so as to obtain a relatively large moving distance of the interlocking portion 19 with a small operation angle of the handle 5.
[0058]
FIGS. 11A and 11B are schematic diagrams showing the rotation operation of the sickle member 2 and the engaging portion 7 accompanying the substantially right and left movement of the interlocking portion 19, wherein FIG. 11A shows an unlocked state and FIG. 11D shows a locked state. ing. The position of the interlocking portion 19 shown in FIG. 11D is the locking side position, and in the first embodiment shown in FIG. 3, the locking side position and the unlocking side position are reversed left and right. The part 19 is moved to the door end side by operating the handle 5 in a direction to open the sliding door 38. Therefore, assuming that the first claw 10 is a claw on which the sickle member 2 is pressed and rotated in the unlocking direction in the same manner as in the first embodiment, the first claw 10 is disposed on the front side 14 of the case. The one claw 10 and the second claw 11 are also arranged to be left and right inverted from the first embodiment. Other rotation of the sickle member 2 due to movement of the interlocking portion 19, a configuration in which the spring member 4 urges the boundary position in both directions, and a configuration in which the interlocking portion 19 holds the locking side position The setting of the free angle is completely the same as that of the first embodiment.
[0059]
Further, as described above, the third embodiment is suitable for a single sliding door such as an entrance, and often does not have a lock mechanism at a mating portion like a sliding door. It is considered that there is a high need to add a lock function. The lock mechanism may be of any type, such as a configuration that regulates the movement of the handle 5 itself by operating the lock knob, or a configuration that regulates the rotation of the sickle member 2, as shown in FIG. 11 as an example. A lock connecting plate 30 is disposed so as to penetrate the case side surface 15, and both ends of the lock connecting plate 30 are protruded from the seat 6 to be connected to a lock knob, and the lock connecting plate is rotated by rotating the lock knob. The means for rotating the sickle member 2 from the projected state by rotating the sickle member 30 in the case 1 is simple.
[0060]
11 (a) to 11 (c) show the unlocked state and the sickle member 2 is rotatable. In the locked state where the engaging portion 7 is projected, the locking knob is pressed as shown in FIG. 11 (d). When the lock connecting plate 30 is rotated by rotating, the rotation of the sickle member 2 in the unlocking direction can be restricted and locked. Further, it is preferable that a leaf spring 31 is urged against the lock connecting plate 30 so that a click feeling is given at the time of locking and releasing.
[0061]
Further, the sliding door sickle lock of the present invention is one of the features of the automatic locking mechanism, and a configuration for reliably preventing rebound even when the sliding door 38 is suddenly closed is effective. It is considered that a very large impact is generated when the closing speed is high, for example, to stop the vehicle so that it does not bounce. Before the sliding door 38 is completely closed, a device for reducing the speed by using friction or the like may be separately attached in some cases. However, in most cases, a device for reducing the speed is used. It is thought that it is necessary for the sickle lock for the sliding door. Therefore, a configuration in which the above mechanism is added to the sickle lock main body a will be described with reference to FIG. 12 as a fourth embodiment, and a configuration in which the above configuration has been added to the receiver c will be described with reference to FIG. 13 as a fifth embodiment.
[0062]
The fourth embodiment is suitable when the engaging portion 7 of the sickle member 2 has a considerable thickness, and has a strong elasticity at the position of the locking side 9 of the engaging portion 7 as shown in FIG. A contact member 32 made of rubber, resin, or the like is mounted and arranged so as to come into contact with the engagement surface 25 of the receiver c in a locked state, and the contact member 32 is slightly elastically resilient only when a very strong bounce occurs. It is configured to absorb the shock by being deformed, and at the same time, it can also add a role of reducing the impact sound at the time of bouncing.
[0063]
The fifth embodiment is suitable for the case where the engaging portion 7 of the sickle member 2 is plate-shaped or thin, and has a structure in which the impact of the rebound is reduced by a mechanism provided in the receiver c. FIG. 13 is a vertical side cross-sectional view of the receiver c according to the fifth embodiment, in which a receiving inner plate 33 having an engaging portion insertion square hole 24 and an engaging surface 25 located thereon, and a mounting hole 18 are shown. A receiving outer case 34 fixed to the holding frame 37 is provided, and both are assembled so that the receiving inner plate 33 can move in the left-right direction with respect to the receiving outer case 34. Although the left and right moving means of the receiving inner plate 33 may have any configuration, a configuration in which both lower portions of the receiving inner plate 33 and the outer receiving case 34 are rotatably assembled with the studs 35 as shown in FIG. It is simple, and a strong pressing spring 36 is inserted between the upper part of the receiving inner plate 33 and the upper part of the receiving outer case 34.
[0064]
FIG. 13A shows a reference position in which the receiving inner plate 33 is pressed in the depth direction by the pressing spring 36. When the sliding door 38 is closed at a low speed, there is no rebound, and the engaging surface of the receiving inner plate 33 remains as it is. 25 and the locking side 9 of the sickle member 2 are engaged and locked. However, when the door is suddenly closed, an action of rebound occurs, and the locking side 9 of the engaging portion 7 pulls the engaging surface 25 of the receiving inner plate 33. By absorbing the shock, the impact can be reduced.
[0065]
At the moment of the rebound, as shown in FIG. 13B, a phenomenon occurs in which the compression spring 36 moves slightly in the direction in which the compression spring 36 is compressed, but at the stage when the rebound force disappears, the receiving inner plate 33 is pressed by the compression spring 36. The frame 37 is stopped by being pulled to the reference position by the force, and a gap between the frame body 37 and the door surface of the sliding door 38 does not occur. Further, the configurations of the fourth embodiment and the fifth embodiment may be used at the same time, and the configuration for alleviating the impact at the time of rebound may be applied to all the configurations from the first embodiment to the third embodiment. Is possible.
[0066]
【The invention's effect】
The operation of the handle is linked directly to the sickle member, the rotation of the sickle member is biased by distributing the rotation of the sickle member between the retracted state and the projected state by the spring member, and the free angle immediately before the engagement part engages with the receiver with the automatic lock mechanism Since the trigger and its surrounding parts are not required at all, the engaging part can be held completely immersed in the case when unlocked, and the engaging part can be held when the sliding door is open. Needless to say, even the trigger does not protrude toward the door, and the danger in traffic can be completely eliminated.
[0067]
The locking and unlocking operation is the same direction as the handle operation when pushing and pulling to open and close the sliding door, the engaging part is in the protruding state at the initial stage of operating the handle in the direction to close the sliding door, just closing the sliding door as it is It can be locked and unlocked at the same time as the handle is operated in the direction of opening the sliding door, and it is possible to open the sliding door further with the handle as it is, that is, a series of operations of opening and closing and locking and unlocking And the operability is excellent.
[0068]
The operation at the time of locking is the same as that of the automatic lock mechanism.When the door is closed, the engaging part of the catch and the sickle member is always engaged, so it is possible to reliably prevent the sliding door from bouncing. Further, even when the rail is inclined due to poor installation or under conditions where the rail is always subject to vibration, it is possible to prevent the phenomenon that the sliding door is opened freely.
[0069]
The sliding door is rapidly closed by mounting an elastic contact member at the engaging side position of the engaging portion, or by forming the receiver with an inner and outer box-shaped member and incorporating a pressing spring between both. It is possible to absorb and mitigate the impact or noise of the rebound when it is hit by the elastic force of the contact member or the compressive force of the pressing spring.
