Description

  The present invention relates to a lock device for a pull-open window.

  Patent Document 1 discloses a conventional pull-open window locking device. This locking device is provided between a cabin body of an industrial vehicle or the like and a window. The cabin body includes an opening formed on the front surface, a pair of left and right guide rails extending from the opening toward the ceiling, a pair of left and right closed strikers provided on the opening side, and a pair of left and right openings provided on the ceiling side. Side striker. The window is movably provided along each guide rail, and closes the opening in the closed position and opens the opening by being positioned on the ceiling in the open position.

  The locking device includes a pair of left and right base members fixed to the right end and the left end of the upper edge of the window, a pair of left and right forks supported to be swingable by each base member, and each base member operable by a passenger And a pair of left and right operation levers supported by each other.

And the displacement of each open side striker is prohibited.

  In this lock device, when the window moves to the closed position, the left and right forks respectively engage with the left and right closed strikers to inhibit the displacement of each closed striker. As a result, the left and right forks are in the closed-side full latch state, so that the lock device can securely lock the window in the closed position. On the other hand, when the window is moved to the open position, the left and right forks respectively engage with the left and right open side strikers to inhibit the displacement of each open side striker. As a result, the left and right forks are in the open-side full latch state, and this lock device can reliably lock the window in the open position.

Japanese Patent No. 3889180

  By the way, in the conventional pull-up type window lock device, when restricting or releasing the swing of the left and right forks to open and close the window, the occupant extends his left hand to the left end at the upper edge of the window and It is difficult to improve the operability because it is necessary to operate the operation lever and extend the right hand to the right end of the upper edge of the window to operate the right operation lever.

  In this locking device, both the left and right forks lock the window in the closed position and the open position. For this reason, the left and right forks are susceptible to a large load and impact from the left and right closed strikers or the open striker at the closed position and the open position, respectively. As a result, backlash tends to occur on the left and right forks, making it difficult to improve durability.

  Further, in this locking device, two sets of locking mechanisms disposed at the left and right ends of the window are configured by the left and right forks and the left and right open side strikers. For this reason, if the window that moves to the open position is rattled in the guide rail, the relative positional relationship between each fork and the open striker fluctuates greatly, and one fork is displaced by one open striker. It is easy for a situation that cannot be prohibited (a situation that does not fully latch) to occur. As a result, there may be a problem in safety performance that the window in the open position suddenly slides toward the closed position.

  The present invention has been made in view of the above-described conventional situation, and realizes safety, operability and durability to prevent a problem that a window in the open position suddenly slides toward the closed position. It is a problem to be solved to provide a lock device for a pull-open window that can realize improvement of the above.

The pull-open window lock device of the present invention is a pull-open window lock device provided between the cabin body and the window,
The cabin body has an opening formed on a side surface, a guide rail extending from the opening toward the ceiling, a closed striker provided on the opening side, and an open striker provided on the ceiling side. And
The window is provided to be movable along the guide rail, closes the opening in a closed position, and opens the opening in the ceiling in the open position.
The locking device includes a closed side entrance for allowing the closed side striker to enter, and a first open side entrance and a second open side entrance for allowing the open side striker to enter, and a center at the upper edge of the window. A base member fixed to the part;
A first fork supported swingably on the base member;
A second fork supported by the base member so as to be swingable independently of the first fork;
A pawl that is supported by the base member so as to be operable by a passenger, and that can regulate or release swinging of the first fork and the second fork,
When the window moves to the closed position, the first fork engages the closed striker and prohibits the closing striker from being displaced together with the closing side entrance, while the window is moved to the open position. When moved, it is configured to engage the open side striker and restrict the displacement of the open side striker together with the first open side entrance to a predetermined range,
The second fork is configured to engage the open side striker and prohibit the displacement of the open side striker together with the second open side entrance when the window moves to the open position. (Claim 1).

  In the pull-open type window locking device of the present invention, when the window moves to the closed position, the first fork engages with the close side striker and prohibits the displacement of the close side striker together with the close side entrance. As a result, the first fork enters the closed-side full latch state, so that the lock device can reliably lock the window in the closed position.

  On the other hand, when the window moves to the open position, the first fork engages with the open side striker and restricts the displacement of the open side striker within a predetermined range together with the first open side entrance. As a result, the first fork enters the open side half latch state. And a 2nd fork engages with an open side striker, and the displacement of an open side striker is prohibited with a 2nd open side advance entrance. As a result, the second fork enters the open-side full latch state. As a result, this locking device can securely lock the window in the open position.

  Even if the second fork does not enter the open-side full latch state due to distortion of the window or opening, etc., the first fork is in the open-side half-latch state, preventing the window from coming off the open position. To do. At this time, since the window is rattled, the passenger can easily recognize that the window is not completely locked in the open position.

  Here, in the locking device of the present invention, the base member is fixed to the central portion at the upper edge of the window, and the first fork, the second fork and the pole are supported on the base member. For this reason, the passenger can restrict or release the swinging of the first fork and the second fork by extending one hand to the center of the upper edge of the window and operating the pole. As a result, this lock device can easily switch and release the closed side full latch state, the open side half latch state, or the open side full latch state. For this reason, the operability is improved as compared with the above-described conventional technique in which the passenger has to operate with the right hand extended to the right end side operation lever and the left end side operation lever extended.

  Further, in this locking device, the first fork locks the window moved to the closed position, but only prevents the window moved to the open position from coming out of the open position. On the other hand, the second fork only locks the window moved to the open position. For this reason, the first fork is likely to receive a large load or impact from the closed striker in the closed position, but is difficult to receive a large load or impact from the open striker in the open position. Further, the second fork is easily subjected to a large load or impact from the open side striker in the open position, but is not subjected to a load or impact from the close side striker in the closed position. Thus, in this locking device, since the first fork and the second fork share and receive a large load and impact from the closed side striker and the open side striker, the load and impact received by each can be greatly reduced. As a result, the play of the first fork and the second fork can be prevented, and the durability is improved.

  Further, in this locking device, the first fork, the second fork, the open side striker, and the like constitute two sets of locking mechanisms disposed at the central portion at the upper edge of the window. For this reason, even if the window moving to the open position is loose in the guide rail, the relative positional relationship between the first fork and the second fork and the open side striker does not fluctuate so much. The displacement of the open side striker can be reliably regulated within a predetermined range, and the second fork can surely prohibit the displacement of the open side striker. For this reason, a situation in which the second fork does not fully latch is unlikely to occur, and as a result, a problem in safety performance that the window in the open position suddenly slides toward the closed position is unlikely to occur.

  Therefore, the pull-opening type window locking device of the present invention achieves safety that prevents the window in the open position from suddenly sliding toward the closed position, and improves operability and durability. realizable.

  The pole may consist of a first fork pole and a second fork pole. The first fork and the second fork may engage with one open striker. Further, the first fork may be engaged with the open striker for the first fork, and the second fork may be engaged with the open striker for the second fork.

  The base member preferably has a channel shape or a hat shape having a first wall portion and a second wall portion facing each other. The first fork has a first closed concave portion that engages with the closed striker and a first open concave portion that engages with the open striker, and is swingably supported by the first wall portion. It is preferable. Moreover, it is preferable that the 2nd fork has the 2nd opening side recessed part engaged with an opening side striker, and is rockably supported by the 2nd wall part. Further, it is preferable that the pole is swingably supported by the first wall portion and the second wall portion.

  According to the said structure, the base member which is a simple shape can be easily manufactured by the bending process of sheet metal, the extrusion molding of aluminum, etc. At this time, the first and second walls for supporting the first and second forks and the pole can be formed at the same time. Moreover, by closing a part of the first and second wall portions, the closed side entrance and the first and second open side entrances can be easily formed. For this reason, simplification and reduction of the number of parts can be realized.

  In addition, if the first fork is formed with only one recess, and the closed side striker and the open side striker are engaged with the recess, the closed side full latch state and the open side half latch state are set. The device configuration is likely to be complicated to achieve. As a specific example, there is a configuration in which the swing direction of the first fork is opposite in the closed side full latch state and the open side half latch state. In this regard, according to the above configuration, the device configuration for realizing the closed-side full latch state and the open-side half latch state can be easily simplified by sharing the roles of the first closed-side recess and the first open-side recess. For example, a configuration in which the swing direction of the first fork is unified in one direction in the closed side full latch state and the open side half latch state can be employed.

  The first fork is swingably supported around the first swing axis, and the second fork is swingably supported around a second swing axis that is concentric with the first swing axis. (Claim 3). In this case, the lock device as a whole can be reduced in size as compared with the case where the swing axis of the first fork and the swing axis of the second fork intersect or deviate.

  The pole is preferably supported so as to be swingable around a pole axis parallel to the first swing axis and the second swing axis. In this case, it is easy to reduce the size as compared with the case where the pole is supported so as to be swingable around an axis that intersects the first swing axis and the second swing axis.

  The pole includes a first swing part that can restrict or release the swing of the first fork, a second swing part that can restrict or release the swing of the second fork, the first swing part, and the second swing part. It is preferable that the moving portion is integrally connected to a lever portion that receives an operation by a passenger (Claim 5). In this case, compared with the case where the pole is composed of the first fork pole and the second fork pole, the closed side full latch state, the open side half latch state, or the open side can be obtained by one operation on the lever portion of the passenger. The full latch state can be switched or released. As a result, this lock device can realize further improvement in operability. Further, since the first oscillating part, the second oscillating part and the lever part are integrated, the number of parts can be reduced. Further, the pole can be easily manufactured by bending a sheet metal or the like.

  In the pull-open type window locking device of the present invention, the first fork and the first open side entrance and the second fork together with the second open side entrance in a state where the displacement of the open striker is regulated within a predetermined range. It is preferable that the position or posture of the lever portion is different between when the displacement of the open side striker is prohibited and when it is not prohibited, and that the passenger can visually recognize the difference in the position or posture. 6). In this case, the passenger can easily distinguish between the open-side full-latch state and the open-side half-latch state by looking at the lever portion, so that further improvement in safety can be realized.

Then, as shown in FIG. 7A, the first fork 10 swings in the direction opposite to the rotation direction R1, and the protrusion 31A slides along the arc portion 10C, and then engages with the stopper portion 10S. To do. As a result, the first swing unit 31 prohibits the swing of the first fork 10 in the rotation direction R1. In this state, the first closed recess 10A engages with the closed striker 95A at the bottom of the closed entrance 51A, thereby prohibiting the displacement of the closed striker 95A. Thereby, since the 1st fork 10 will be in a closed-side full latch state, this locking device 1 can lock the window 99 reliably in a closed position.

  At the same time, the closed-side striker 95A enters the closed-side advancement port 52A from the state shown in FIG. 6B, but as shown in FIG. 7B, the closed-side striker 95A is urged in the rotational direction R1. The two forks 20 are not engaged. At this time, the protrusion portion 32C contacts the arc portion 20C, whereby the posture P1 of the lever portion 33 when the first fork 10 is in the closed side full latch state is determined.

  When the lever portion 33 is pushed forward from the state shown in FIG. 7B by the passenger, the first and second swinging portions 31 and 32 are moved as shown in FIGS. 6A and 6B. The protrusion 31A is separated from the stopper 10S by swinging integrally in the direction opposite to the rotation direction R2. Then, the first fork 10 is urged by the torsion coil spring 18 and swings in the rotation direction R1, and pushes the closing striker 95A forward to disengage from the closing entrance 51A. Thereby, the lock is released when the window 99 is in the closed position. As a result, the passenger can slide the window 99 from the closed position toward the open position. At this time, the protrusion 31C comes into contact with the arc portion 10C, so that the posture P2 of the lever 33 when the lock is released at the closed position of the window 99 is determined as shown in FIG. 6B.

  Further, when the window 99 is moved to the open position, the locking device 1 assumes a posture that is rotated approximately 90 ° rearward, and approaches the open striker 95B positioned rearward substantially horizontally from the front. If it does so, the open side striker 95B will approach into the 1st open side entrance 51B, pushing the 1st open side recessed part 10B from the state shown to Fig.8 (a). Then, as shown in FIG. 9A, the first fork 10 swings in the direction opposite to the rotation direction R1, and the protrusion 31A slides along the arc 10C, and then engages with the stopper 10S. To do. As a result, the first swing unit 31 prohibits the swing of the first fork 10 in the rotation direction R1. In this state, the first open side recess 10B is engaged with the open side striker 95B at the intermediate portion of the first open side entrance 51B, whereby the closed side striker 95A is held in the first open side entrance 51B. . However, in this state, the first swing part 31 does not prohibit the swing of the first fork 10 in the direction opposite to the rotation direction R1. For this reason, the closed side striker 95A can be displaced to the bottom of the first open side entrance 51B. Thereby, the 1st fork 10 will be in an open side half latch state.

  At the same time, the open side striker 95B enters the second open side entrance 52B while pushing the second open side recess 20B from the state shown in FIG. 8B. Then, as shown in FIG. 9B, the second fork 20 swings in the direction opposite to the rotation direction R1. At this time, the protrusion portion 31A engages with the stopper portion 10S, and the protrusion portion 32C contacts the arc portion 20C, so that the posture P3 of the lever portion 33 when the first fork 10 is in the open-side half latch state is Determined.

  Then, the open side striker 95B enters from the state shown in FIG. 9B to the bottom of the second open side entrance 52B while further pressing the second open side recess 20B. Then, as shown in FIG. 10 (b), the second fork 20 further swings in the direction opposite to the rotation direction R1, and the protrusion 32A slides along the arc 20C, and then engages with the stopper 20S. Match. As a result, the second swing part 32 prohibits the swing of the second fork 20 in the rotation direction R1. In this state, the second open side recess 20B engages with the open side striker 95B at the bottom of the second open side entrance 52B, thereby prohibiting the displacement of the open side striker 95B. Thereby, since the 2nd fork 20 will be in an open side full latch state, this locking device 1 can lock the window 99 reliably in an open position.

  At the same time, the open side striker 95B enters from the state shown in FIG. 9A to the bottom of the first open side entrance 51B while further pressing the first open side recess 10B. Then, as shown in FIG. 10A, the first fork 10 further swings in the direction opposite to the rotation direction R1, and the displacement of the open side striker 95B is allowed.

  At this time, as shown in FIG. 10B, the protrusion 32A engages with the stopper 20S, and the stopper 32S comes into contact with the arc 20C, so that the second fork 20 is in an open-side full latch state. In this case, the posture P4 of the lever portion 33 is determined.

  When the lever portion 33 is pushed further forward from the posture P3 shown in FIG. 9B by the passenger from the state shown in FIG. 10B, the first and second swinging portions 31 and 32 rotate in the rotational direction. As shown in FIG. 9B, the protrusion 32A moves away from the stopper 20S as shown in FIG. 9B. Further, as shown in FIG. Separates from the stopper portion 10S. Then, the first and second forks 10 and 20 are urged by the torsion coil springs 18 and 28 to swing in the rotation direction R1, and push the open side striker 95B forward to move the first and second open side entrances 51B. , 52B. As a result, the lock is released when the window 99 is in the open position. As a result, the passenger can slide the window 99 from the open position toward the closed position. At this time, the protrusion 31C comes into contact with the arc portion 10C, so that the posture P5 of the lever portion 33 when the lock is released at the open position of the window 99 is determined as shown in FIG. 8B.

  The postures P1 to P5 of the lever portion 33 are greatly different as shown in FIGS. This is set such that the distance between the first and second swing axis X1 and X2 and the arc portion 10C is different from the distance between the first and second swing axis X1 and X2 and the arc portion 20C. This is realized by setting the distance between the pole shaft X3 and the lower end of the lever portion 33 to be longer than the distance between the shaft X3 for projection and the protrusions 31A and 32A. For this reason, the passenger can easily visually recognize which of the postures P1 to P5 the posture of the lever portion 33 is.

  In the locking device 1, even if the second fork 20 does not enter the open-side full latch state due to the distortion of the window 99 or the opening 92, the first fork 10 is open-side half as shown in FIG. By being in the latched state, the problem that the window 99 is disengaged from the open position is prevented. At this time, since the window 99 is rattled, the passenger can easily recognize that the window 99 is not completely locked in the open position.

  Here, in the locking device 1 of the embodiment, the base member 50 is fixed to the central portion of the upper end edge of the window 99, and the first fork 10, the second fork 20, and the pole 30 are supported by the base member 50. . For this reason, the passenger can restrict or release the swinging of the first fork 10 and the second fork 20 by extending one hand to the center of the upper edge of the window 99 and operating the pole 30. As a result, the lock device 1 can easily switch and release the closed side full latch state, the open side half latch state, or the open side full latch state. For this reason, the operability is improved as compared with the above-described conventional technique in which the passenger has to operate with the right hand extended to the right end side operation lever and the left end side operation lever extended.

  Further, in this locking device 1, the first fork 10 locks the window 99 moved to the closed position, but only prevents the window 99 moved to the open position from being removed from the open position. On the other hand, the second fork 20 only locks the window 99 moved to the open position. For this reason, the first fork 10 is easily subjected to a large load and impact from the closed striker 95A in the closed position, but is difficult to receive a large load and impact from the open striker 95B in the open position. Further, the second fork 20 is easily subjected to a large load or impact from the open side striker 95B in the open position, but is not subjected to a load or impact from the close side striker 95A in the closed position. Thus, in this locking device 1, since the first fork 10 and the second fork 20 share and receive a large load and impact from the closed side striker 95A and the open side striker 95B, the load and impact received by each are greatly increased. As a result, the play of the first fork 10 and the second fork 20 can be prevented, and the durability is improved.

  Further, in this locking device 1, the first and second forks 10, 20 and the open side striker 95 </ b> B constitute two sets of locking mechanisms disposed in the central portion of the upper end edge of the window 99. For this reason, even if the window 99 moving to the open position is rattled in the guide rails 94L and 94R, the relative positional relationship between the first and second forks 10 and 20 and the open-side striker 95B does not vary much. Therefore, the first fork 10 can surely regulate the displacement of the open side striker 95B within a predetermined range, and the second fork 20 can surely prohibit the displacement of the open side striker 95B. For this reason, a situation in which the second fork 20 is not fully latched is unlikely to occur, and as a result, the safety performance problem that the window 99 in the open position suddenly slides toward the closed position is unlikely to occur.

  Therefore, the pull-opening type window locking device 1 of the embodiment achieves safety that prevents a problem that the window in the open position suddenly slides toward the closed position, and improves operability and durability. Can be realized.

  In the locking device 1, the base member 50 has a hat shape having a first wall portion 51 and a second wall portion 52 that face each other. The first fork 10 has a first closed recess 10A that engages with the closed striker 95A and a first open recess 10B that engages with the open striker 95B. The second fork 20 has a second open-side recess 20B that engages with the open-side striker 95B, and is supported by the second wall portion 52 so as to be swingable. Further, the pole 30 is swingably supported by the first and second wall portions 51 and 52. With such a configuration, in the lock device 1, the base member 50 having a simple shape can be easily manufactured by bending a metal plate, extruding aluminum, or the like. At this time, the first and second walls 51 and 52 for supporting the first and second forks 10 and 20 and the pole 30 can be formed at the same time. Moreover, the closed side entrances 51A and 52A and the 1st and 2nd open side entrances 51B and 52B can be easily formed by notching a part of the 1st and 2nd wall parts 51 and 52. FIG. For this reason, simplification and reduction of the number of parts can be realized.

  In addition, only one recess is formed in the first fork 10 instead of the first and second closed recesses 10A and 10B, and the closed striker 95A and the open striker 95B engage with the recess. In this case, for example, it is conceivable to employ a complicated configuration in which the swing direction of the first fork 10 is opposite in the closed side full latch state and the open side half latch state. In this regard, according to the above configuration, the swinging direction of the first fork 10 can be changed between the closed side full latch state and the open side half latched state by sharing the roles of the first closed side recessed portion 10A and the first open side recessed portion 10B. The apparatus configuration can be simplified by unifying the direction R1.

  Further, in the locking device 1, the first fork 10 is supported so as to be swingable around the first swing axis X1, and the second fork 20 is a second swing that is concentric with the first swing axis X1. It is supported so as to be swingable around the dynamic axis X2. With this configuration, the locking device 1 as a whole can be reduced in size compared to the case where the first swing axis X1 and the second swing axis X2 intersect or deviate.

  Further, in this locking device 1, the pole 30 is supported so as to be swingable around a pole axis X3 parallel to the first and second swing axis X1 and X2. For this reason, compared with the case where the pole 30 is supported so as to be swingable around the axis intersecting with the first and second swing axis X1, X2, it is easy to reduce the size.

  Moreover, in this locking device 1, compared with the case where the first fork pole and the second fork pole that operate independently of the first fork pole are employed, the 1 for the passenger's lever 33 is provided. By the operation of the rotation, the pole 30 can be switched or released between the closed side full latch state, the open side half latch state, or the open side full latch state. As a result, this locking device 1 can realize further improvement in operability. Moreover, since the 1st rocking | swiveling part 31, the 2nd rocking | swiveling part 32, and the lever part 33 are integrated, the number of parts can be reduced. Further, the pole 30 can be easily manufactured by bending a sheet metal or the like.

  Further, in this locking device 1, the passenger can easily distinguish the posture P4 of the lever portion 33 corresponding to the open side full latch state and the posture P3 of the lever portion 33 corresponding to the open side half latch state. It can be reliably recognized whether or not the window 99 is securely locked in the open position. As a result, the locking device 1 can realize further improvement in safety.

  While the present invention has been described with reference to the embodiments, it is needless to say that the present invention is not limited to the above-described embodiments and can be appropriately modified and applied without departing from the spirit thereof.

  The present invention is applicable to vehicles and the like.
