Description

  The present invention relates to a locking device used for a raising / lowering window that opens and closes by sliding a shoji screen up and down along a window frame.

The raising and lowering windows that open and close by sliding at least one of the upper and lower shojis arranged in the vertical direction along the window frame should be free from rain and do not take up space because they fit within the wall thickness. In addition, it can be installed at places where the opening is restricted due to structural reasons.
As a locking device for such a raising / lowering window, lock pieces (locks and latches) that are provided at the left and right ends of the side of the lower shoji and protrude from the left and right prospective surfaces to the left and right are outward in the left and right directions. The lever is urged by a spring and locked in a state where the lock piece is engaged with a receiving hole (lock receiving hole, engagement hole) formed in the vertical frame, and a swingable operation lever or an up-and-down movement as an operation unit There is a configuration in which the lock piece is moved inward in the left-right direction against the biasing force of the spring and unlocked by operating a possible knob (see, for example, Patent Documents 1 and 2). .

Japanese Utility Model Publication No. 58-195757 No. 05-022607 JP-A-2005-36425

In the configuration of the locking device for the raising and lowering window as in Patent Documents 1 and 2, the operating portions provided at the left and right ends of the side of the lower shoji are located on the lower side, and the handle is fixed to the recumbent It can be unlocked by operating it close to the hand-held piece or finger-hanging portion, and the window can be opened by sliding the shoji screen upward in that state.
However, in a state where the shoji is closed and locked, the lock piece is only engaged with the receiving hole while being urged outward in the left-right direction by the spring, so that it resists the urging force of the spring by, for example, an elongated wire. Thus, there is a possibility that the lock piece is moved inward in the left-right direction and unlocked.
Therefore, in order to improve crime prevention, a separate sub-block (for example, a stopper configured to be able to appear and move indoors and outdoors by operating the indoor side operation unit as in Patent Document 3 is provided below the vertical shovel of the upper shoji. Etc.), etc., and the cost increases.

In addition, since the locking device itself including the operation portion and the handle portion is long in the left-right direction, the installation position of the locking device is limited to the recumbent (lower arm or upper arm) of the lower shoji, Since the operation part and the handle part at both ends protrude to the indoor side, the operation part and the handle part are easily visible through the glass from the outdoor side.
Therefore, the position of the locking device is easy to understand when unauthorized unlocking is performed as described above, which is not preferable from the viewpoint of crime prevention.
Furthermore, the operation part and the handle part at the left and right ends of the lower shoji protrude to the indoor side, and since there are many parts protruding to the indoor side due to the necessity from such a functional aspect, it is visible from the indoor side. The appearance cannot be made clean and smooth.

  Therefore, in view of the above-described situation, the present invention is intended to solve the problem that the security can be improved while suppressing an increase in cost, and the degree of freedom of the installation position is high due to the compact configuration, which is visually recognized from the indoor side. An object of the present invention is to provide a locking device for a raising / lowering window which has a clean and smooth appearance.

In order to solve the above-mentioned problem, the locking device for the raising / lowering window according to the present invention is a locking device used for the raising / lowering window that opens and closes by sliding the shoji up and down along the window frame, and is a left end portion of the lower shoji. Alternatively, a main body attached to the right end, a slide body supported by the main body so as to be movable in the vertical direction, and provided with a knob that can be operated from the indoor side, and a left and right direction by the main body on the outdoor side of the slide body A lock body that is supported movably and elastically biased in the window frame direction, moves in the left-right direction in conjunction with the movement of the slide body in the vertical direction, and has a lock piece provided on the window frame side, and When the lower shoji is closed, the slide piece is moved relative to the main body in a state where the lock piece protrudes toward the window frame and engages a receiving hole provided in the window frame by the elastic biasing force. To make Ri and a latching means for latching said sliding member, the outdoor side surface of the slide body, the upper end of the inclined guide surface and the inclined guide surface inclined to the window frame direction as they extend upwardly facing lateral inward A vertical guide surface that extends in the vertical direction connected to the portion, and an operation piece that protrudes in the indoor direction provided on the lock body is brought into contact with the guide surface from the inner side in the horizontal direction, and the lower shoji is closed The operated piece comes into contact with the upper and lower guide surfaces, and the lock piece is engaged with the receiving hole. From this state, the slide body is moved downward with respect to the main body. It is characterized by being hooked .

According to such a configuration, the slide body that is movable in the vertical direction with respect to the main body and the lock body that is movable in the left-right direction with respect to the main body are interlocked, and the lock body is in the window frame direction (outside in the left-right direction). F) When the slide body is not hooked against the main body because it is elastically biased, for example, the position where the receiving hole on the window frame side is provided when opening and closing the lower shoji with the lower arm When the lock piece comes to the door, the lock is automatically locked, and the locked state can be released by the slide body interlocked with the lock body.
Therefore, by providing a receiving hole in the window frame according to the position of the lock piece in the closed state of the lower shoji, there is no state that the lower shoji is closed and not locked. Can be prevented.
In addition, when the lower shoji is closed and the lock piece is engaged with the receiving hole and locked, and the slide body is further moved relative to the main body, the slide body is moved relative to the main body by the action of the latching means. In this state, the lock body that is interlocked with the slide body cannot be moved against the elastic biasing force, so that it is possible to improve crime prevention while preventing an increase in cost without providing a separate sub-block. Can do.

In addition, the knob provided on the slide body may be operated when releasing the locked state, when the latching means is actuated to make the latched state, and when releasing the latched state. Can be made relatively small and a hand-held portion like the locking device of Patent Documents 1 and 2 is unnecessary, so that it can be difficult to see through the glass from the outdoor side.
In addition, the left and right operation portions such as the locking devices of Patent Documents 1 and 2 are operated so as to be close to the lower handle portion, and the lower shoji is held with the handle portion. Since it is not a configuration for raising and lowering, it is possible to form the main body in a vertically long form so that the main body and the slide body supported by the main body so as to be movable in the vertical direction are contained within the width of the vertical shaft. Since it is easy, the freedom degree of the up-down direction position which installs a locking device with respect to a lower shoji becomes large.
Therefore, since the position of the locking device is difficult to understand from the outdoor side, the crime prevention property can be further enhanced.
Further, unlike the configuration in which the operation parts at the left and right ends of the lower shoji and the lower hand hooks project to the indoor side as in the locking devices of Patent Documents 1 and 2, only the left and right sides of the lower shoji are compared. Since only a small knob protrudes to the indoor side, the appearance visually recognized from the indoor side can be made clean and smooth.

Furthermore , on the outdoor side surface of the slide body, an inclined guide surface that faces inward in the left-right direction and inclines toward the window frame as it goes upward, and an upper and lower guide surface that extends in the vertical direction connected to the upper end of the inclined guide surface are formed. In addition, an operation piece provided in the lock body and projecting in the indoor direction is brought into contact with the guide surface from the inner side in the left-right direction so that the operation piece touches the upper and lower guide surfaces when the lower shoji is closed. a state in which the lock piece is engaged with the receiving holes in contact, since the slide body is latched by moving from the state of the slide member downward relative to the body, simple to the latching means Since it can comprise, cost can be reduced.
In addition, since the slide body is configured to be hooked to the main body by moving the slide body downward, the direction in which the knob is operated to make the hook state is the same as the direction in which the lower shoji is closed. At the same time, the direction to operate the knob to release the latched state is the same as the direction to open the lower shoji, so the operation for making the latched state and the operation for releasing the latched state are easy to understand Performance can be improved and erroneous operation can be prevented.

  As described above, according to the raising / lowering window locking device according to the present invention, it is easy to make the width in the left-right direction small, and it can be attached to the left end or right end of the lower shoji, By operating a small knob, the slide body can be hooked to the main body and the movement of the lock body interlocking with the slide body can be regulated, so that crime prevention is improved while suppressing an increase in cost. This provides a remarkable effect that the installation position is highly flexible and the appearance visually recognized from the indoor side becomes clean and smooth.

The state which latched on the main body is shown, and the slide body is shown with the virtual line.

In this specification, the front side (see arrow A in the figure) from the indoor side (see ID in the figure) to the outdoor side (see OD in the figure) is the front, the rear is the rear, and the left and right are the front The figure seen from the indoor side shall be the front view.
A direction from the lower shoji L toward the outside in the left-right direction (a direction from the vertical saddle of the lower shoji L to the vertical frame S of the adjacent window frame F) is referred to as “window frame direction”. The side close to the frame S is referred to as “window frame side”.

The raising / lowering window HW shown in FIGS. 1 to 3 is of a single hang type in which the upper shoji U is a fixed shoji and the lower shoji L is a movable shoji, for example, has a recumbent (lower arm) of the lower shoji L The lower shoji L can be opened and closed by sliding it vertically along the window frame F.
In addition, the locking device 1 according to the embodiment of the present invention is attached to the lower part of the left vertical rod of the lower shoji L of the lowering / lowering window HW and is provided on the left vertical frame S of the window frame F. When the lock piece 4B is engaged with the holes 17, 18, 19 and locked, the slide body 3 is hung on the main body 2 by the latching means described later by operating the knob 3B protruding to the indoor side. By stopping, it can be locked so as to regulate the movement of the lock piece 4B.
In addition, what is necessary is just to provide the receiving hole of a vertical frame in the position which wants to lock.
In addition, the locking device 1 can be used with the same configuration as the one attached to the lower part of the left downpile and attached to the right side downpile symmetrically, or attached to both the left and right side downpiles. May be.
Furthermore, the raising / lowering window in which the locking device 1 is used is not limited to the above-described single-hanging type raising / lowering window HW, and is a double-hanging type in which both the upper shoji U and the lower shoji L are movable shoji. Also good.
Furthermore, the locking device 1 can be applied to a raising / lowering window having a structural difference such as the presence or absence of a balancer or the presence or absence of a crescent lock.

As shown in FIGS. 4 to 6, the locking device 1 is supported by a main body 2 having a generally rectangular shape in front view that is long in the vertical direction, and is movable in the vertical direction, and can be operated from the indoor side (rear side). The slide body 3 having a generally rectangular shape in front view and provided with the knob 3B is supported by the main body 2 so as to be movable in the left-right direction on the outdoor side (front side) of the slide body 3, and on the window frame side (left side). The lock body 4 is provided with a lock piece 4B.
The main body 2 is a lock body that is positioned on the outdoor side (front side) of the base body 2A that is long in the vertical direction and has a substantially rectangular shape in front view, left and right side walls 2B and 2C that are erected rearward from the left and right edges. 4A, the guide body 2A is movably supported in the left-right direction. The base 2A has upper and lower guide slots 5A, 5B which are long in the vertical direction on the right side of the left side wall 2B extending in the vertical direction. A central opening 6 having a rectangular shape when viewed from the front is formed in the central portion, and attachment holes 7A and 7B for attaching the base 2A to the lower shoji L are formed in the upper and lower ends.
Further, upper and lower leaf spring support grooves 8A and 8B are formed at the center of the right side of the left side wall 2B of the base 2A (on the left side of the central opening 6), and upper and lower ends are formed in the support grooves 8A and 8B. Is attached to the main body 2 with the convex portion directed to the right side.
Further, a spring support shaft 10A protruding in the window frame direction (leftward) from the right wall of the lock body guide portion 2D is inserted into the coil of the compression coil spring 10, and the right end of the compression coil spring 10 is the left surface of the right wall. And held in contact with the

The slide body 3 is composed of a base body 3A having a substantially rectangular shape in front view that is long in the up-down direction and a knob 3B that is long in the left-right direction projecting at the center in the up-down direction on the indoor side (rear side). Slide shafts 12A and 12B extending outwardly (front side) are projected.
In addition, the outdoor side surface (front surface) of the base body 3A faces the right side and is connected to an inclined guide surface 13 that inclines in the window frame direction (leftward) as it goes upward, and the upper end portion of the inclined guide surface 13 in the vertical direction. An extending vertical guide surface 14 is formed, and an engagement concave portion 16 is formed on the side surface (left side surface) of the base body 3A by a vertical surface 15 that is long in the vertical direction and convex and concave portions on the upper side.
The lock body 4 includes a substantially rectangular plate-like base body 4A extending in the left-right direction, a lock piece 4B extending from the base body 4A in the window frame direction (leftward), a spring receiving piece 4C extending from the base body 4A in the indoor direction (rearward), and a spring receiver. An extended piece 4D extending from the rear end of the piece 4C in an inclined direction toward the window frame (left) in the indoor direction (rear), and an operated piece protruding further in the indoor direction (rear) from the rear end of the extended piece 4D 4E.

When the lock body 4 is accommodated in the lock body guide portion 2D of the main body 2 with the left end of the compression coil spring 10 in contact with the right surface of the spring receiving piece 4C, the lock body 4 is elastically biased by the compression coil spring 10. The lock body 4 is in a state in which the lock piece 4B at the left end protrudes in the window frame direction (leftward) from the opening 9 (see FIG. 5) on the left surface of the lock body guide portion 2D and the base body 2A of the main body 2 The operated piece 4E protrudes from the central opening 6 in the indoor direction (backward).
In this state, the slide body 3 is brought into contact with the operated piece 4E of the lock body 4 on the inclined guide surface 13 or the upper and lower guide surfaces 14, and the plate is placed on the upper and lower surfaces 15 of the slide body 3 or on the left side of the engagement recess 16. Assemble between the left and right side walls 2B, 2C of the main body 2 so that the convex portion of the spring 11 is located, and insert the upper and lower slide shafts 12A, 12B of the slide body 3 into the upper and lower guide slots 5A, 5B of the main body 2. Then, for example, a ring is fitted to the tip of the slide shafts 12A and 12B and the shaft end is caulked to prevent the shaft from coming off and to be integrated.

The locking device 1 integrated in this way uses the mounting holes 7A and 7B because one of the mounting holes 7A and 7B of the base body 2 is exposed by sliding the slide body 3 up and down relative to the main body 2. And can be easily attached to the lower shoji L.
Further, the lock body 4 is elastically biased toward the window frame (leftward) by the compression coil spring 10, and the operated piece 4E of the lock body 4 abuts against the inclined guide surface 13 or the upper and lower guide surfaces 14 of the slide body 3. Therefore, in a state where the operated piece 4E slides on the inclined guide surface 13 of the slide body 3, when the slide body 3 is moved upward, the lock body 4 is moved rightward and the slide body 3 is moved downward. The lock body 4 moves in the left-right direction in conjunction with the movement of the slide body 3 in the vertical direction so that the lock body 4 moves to the left.
Further, as shown in FIGS. 5B and 6B, in a state where the slide body 3 is moved to the lower end, the operated piece 4E of the lock body 4 abuts on the upper and lower guide surfaces 14 of the slide body 3. At the same time, the convex portion of the leaf spring 11 engages with the engaging concave portion 16 on the side surface (left side surface) of the window frame of the slide body 3, so that the slide body 3 is hooked on the main body 2.
In other words, in the present embodiment, the leaf spring 11 and the engaging recess 16 constitute a latching means for latching the slide body 3 by moving the slide body 3 relative to the main body 2.

When the relative position of the slide body 3 with respect to the main body 2 as shown in FIGS. 6A and 7A is on the upper side, the slide body 3 and the lock body 4 are interlocked and compressed as described above. Since the elastic biasing force of the coil spring 10 acts on the lock body 4, when the hand is released from the knob 3B, the lock body 4 automatically moves downward in the window frame direction (leftward).
At this time, if there are receiving holes 17, 18, and 19 at the height of the lock piece 4B of the lock body 4, the lock piece 4B protrudes in the window frame direction (to the left) to the receiving holes 17, 18 or 19. Automatically engaged and locked, for example, the state shown in FIG.
In addition, when there are no receiving holes 17, 18, 19 at the height position of the lock piece 4 </ b> B of the lock body 4, the lock piece 4 </ b> B is pressed against the vertical frame. ) Can be opened and closed by sliding the lower shoji L (see FIGS. 1 and 2) up and down along the window frame F.

When the state shown in FIG. 7B is a state where the lower shoji L shown in FIG. 1 is closed, the knob 3B is further pushed down to move the slide body 3 to the lower end, as shown in FIGS. In the state shown in c), the slide body 3 is hooked on the main body 2 by the above-described hooking means. In this state, the slide body 3 does not move unless the knob 3B is operated.
Therefore, the lock body 4 interlocked with the slide body 3 is locked so as not to move to the right against the elastic biasing force of the compression coil spring 10.
When the slide body 3 is pushed up by operating the knob 3B from this state and the convex portion of the leaf spring 11 is moved from the engagement concave portion 16 of the slide body 3 to the upper and lower surfaces 15, the locked state (hanging state) is released. The
Further, when the slide body 3 is pushed up by operating the knob 3B, the lock body 4 interlocked with the slide body 3 moves rightward and comes out of the receiving hole 17, so that the locked state is released. The shoji L can be opened.

According to the configuration of the locking device 1 as described above, the slide body 3 movable in the vertical direction with respect to the main body 2 of the locking device 1 and the lock body 4 movable in the left-right direction with respect to the main body 2 are interlocked. At the same time, since the lock body 4 is elastically biased in the window frame direction (outward in the left-right direction), for example, when the slide body 3 is not hooked on the main body 2, the lower shoji is held with a lower arm, for example. When the lock piece 4B comes to the position where the receiving holes 17, 18, 19 of the window frame F (vertical frame S) are provided when L is opened and closed, the lock piece 4B is automatically locked, and this locked state is interlocked with the lock body 4. It can be released by operating the knob 3B of the slide body 3.
Therefore, by providing the receiving hole 17 in the vertical frame S of the window frame F in accordance with the position of the lock piece 4B when the lower shoji L is closed, the lower shoji L is locked in a closed state. Since there is no state, forgetting to lock can be prevented.
In addition, when the lower shoji L is closed and the lock piece 4B is engaged with the receiving hole 17 and locked, the slide body 3 is further moved relative to the main body 2 to act as the latching means 11 and 16. As a result, the slide body 3 is latched to the main body 2, and in this state, the lock body 4 interlocked with the slide body 3 cannot be moved against the elastic biasing force of the compression coil spring 10, so Crime prevention can be enhanced while suppressing an increase in cost without providing a block.

Further, the knob 3B provided on the slide body 3 is only required to be operated when releasing the locked state, when the latching means 11 and 16 are actuated, and when the latched state is released. Since the size and the amount of protrusion to the indoor side can be made relatively small, and a hand-held portion like the locking device of Patent Documents 1 and 2 is unnecessary, it can be made difficult to be seen through the glass from the outdoor side.
In addition, the left and right operation portions such as the locking devices of Patent Documents 1 and 2 are operated so as to be close to the lower handle portion, and the lower shoji is held with the handle portion. Since it is not the structure which raises / lowers, the main body 2 is formed in the shape long in the up-down direction like this Embodiment, and the slide body 3 supported so that the vertical movement by the main body 2 and this main body 2 is supported by the vertical shaft Therefore, the degree of freedom in the vertical position where the locking device 1 is installed with respect to the lower shoji L is increased.
Therefore, since the position of the locking device 1 is difficult to understand from the outdoor side, the crime prevention property can be further enhanced.
Further, unlike the configuration in which the operation parts at the left and right ends of the lower shoji and the lower hand hooks project to the indoor side as in the locking devices of Patent Documents 1 and 2, only the left and right sides of the lower shoji L are different. Since the relatively small knob only protrudes to the indoor side, the appearance visually recognized from the indoor side can be made clear and smooth.

  Furthermore, according to the configuration of the present embodiment, the slide body 3 is hooked to the main body 1 by moving the slide body 3 downward. The direction of operation is the same as the direction of closing the lower shoji L, and the direction of operating the knob 3B to release the hooked state is the same as the direction of opening the lower shoji L. Therefore, the operation for releasing the latched state and the operation for releasing the latched state can be easily understood and the operability can be improved, and the erroneous operation can be prevented.
