Description

  The present invention relates to a window locking device used for a sliding door type glass door, an aluminum sash frame window, and the like, and more particularly to a window locking device used for auxiliary locking in addition to a main locking device.

  In recent years, for example, in order to prevent crimes, an auxiliary locking device has been installed on a sliding door type glass door or an aluminum sash frame window in addition to a main locking device such as a crescent lock.

  As such a locking device, the auxiliary lock for windows of the following patent document 1 and the auxiliary lock for aluminum sash of the following patent document 2 are known.

  In Patent Document 1, a substrate that is attached to one glass window or the like with a double-sided tape, and a lock plate that can be rotated through a long hole extending in the vertical direction are provided on the substrate, and the lock plate is rotated. A window auxiliary lock that restricts the opening operation of the other glass window by being unfolded is described.

  Patent Document 2 is composed of a box-shaped substrate that is attached with a double-sided tape, a undulation plate that can be stored in the substrate, and a spring material installed on the back of the undulation plate, and by a one-touch pushing operation, An auxiliary lock for an aluminum sash that restricts the opening operation of the glass window with the undulating plate standing is described.

  By the way, since such a locking device is directly attached to the sliding door type opening / closing body to be opened and closed, in order to reduce the burden of the opening / closing operation of the opening / closing body, it is required to be configured to be compact and lightweight.

  In this regard, according to the structure of the above-mentioned Patent Document 1, since a vertical space for pulling up the lock plate is required, there is a problem that the apparatus itself is necessarily increased in size and weight. .

  On the other hand, according to the structure of the above-mentioned patent document 2, since the opening of the glass window is restricted only by raising and lowering the undulation plate, the apparatus can be configured compactly, and the above-described request for downsizing can be met.

However, there is a problem that the structure of Patent Document 2 is not sufficient in crime prevention performance.
In other words, the auxiliary lock for aluminum sash of Patent Document 2 described above is provided by installing a spring material on the back of the undulation plate and pushing the end of the undulation plate so that the unlocking can be performed by one-touch pushing operation. The undulation plate is configured to switch the undulation state.
For this reason, when an intruder breaks the window glass and enters the room, the auxiliary lock can be unlocked relatively easily if the end of the undulation plate is pressed from the outside with one touch. The function is lost.

  Therefore, an object of the present invention is to provide a window locking device that is compact and lightweight, and further improved in crime prevention, in a window locking device attached to a sliding door type opening / closing body.

  The window locking device of the present invention is a window locking device to be attached to a sliding door type opening / closing body, and is located on the side of the plate body made of a synthetic resin having a sticking portion on the back surface and opened. Synthetic resin plate locking piece that is flush with the plate body at the time of locking, and the plate body and the plate locking piece are connected by press-fitting at the side ends, and the rotation axis of the plate locking piece at the time of locking And a metal rotating pin.

According to the said structure, it attaches to a sliding door type opening / closing body by attaching to an opening / closing body in the sticking part of a plate main body, and rotates a plate locking piece against the sliding resistance by the press fit fixation of a rotation pin. Thus, the unlocked state and the locked state are switched.
For this reason, the operator cannot rotate the plate locking piece unless a certain force or more is continuously applied to the plate locking piece when switching the unlocking and locking.
In particular, when operating from outside, it is difficult for an intruder or the like to perform an unlocking operation because the plate locking piece on the back side of the sash frame or the like must be rotated with a fingertip or the like.

  Further, in this window locking device, since the plate locking piece is simply rotated to switch between unlocking and locking, the device itself can be made compact. Furthermore, since the plate body and the plate locking piece are formed of synthetic resin, the weight can be reduced.

  When the plate main body and the plate locking piece are formed in a rectangular shape, they can be matched with a sash frame or the like, and the appearance when the window locking device is attached can be improved. But the shape of a plate main body and a plate latching piece is not limited to rectangular shape, Other shapes, such as a round shape and a triangular shape, may be sufficient.

In one embodiment of the present invention, the side surface of the rotation side end portion of the plate locking piece is inclined so as to form an acute angle with the front surface.
According to the above configuration, since the side surface of the rotation-side end portion of the plate locking piece is inclined so as to form an acute angle with the front surface, the operator locks the plate locking piece from the front side, that is, from the indoor side. When rotating in the direction, the fingertip is easily caught on the rotation side end of the plate locking piece, and the plate locking piece is easily rotated. On the other hand, when the plate locking piece is rotated in the unlocking direction, the inclined side surface forms an obtuse angle with the back surface, so that the fingertip is less likely to be caught on the rotation side end, and the plate locking piece is rotated. It becomes difficult.
Therefore, it is possible to provide a window locking device that is easy to operate in the locking direction and difficult to operate in the unlocking direction, and it is difficult to operate in the unlocking direction while improving the operability in the locking direction. In this way, crime prevention can be improved.

In one embodiment of the present invention, a concave hook groove is provided on the side surface of the rotation side end of the plate locking piece.
According to the above configuration, since the concave hooking groove is provided on the side surface of the rotation side end of the plate locking piece, the fingertip is hooked on the plate locking piece when the operator operates the plate locking piece. This facilitates the rotation of the plate locking piece.

  Therefore, the operator can easily perform the rotation operation of the locking plate while receiving the rotation resistance of the plate locking piece due to the press-fitting and fixing of the rotation pin.

In one embodiment of the present invention, the width of the plate locking piece is shorter than the width of the plate body.
According to the above configuration, since the width of the plate locking piece is shorter than the width of the plate main body, in the unlocked state, that is, in a state where the plate locking piece is positioned flush with the side of the plate main body, The end of the plate locking piece is visually recognized one step lower than the end of the plate body.

  Therefore, the operator can easily identify the position of the plate locking piece from the plate body, and can easily operate the plate locking piece because there is a gap.

  In one embodiment of the present invention, the plate body and the plate locking piece are different in color.

  According to the above configuration, since the plate main body and the plate locking piece are different in color, in the unlocked state, that is, in a state where the plate locking piece is flush with the side of the plate main body, The piece will be visually distinct from the plate body.

  Therefore, the operator can easily identify the position of the plate locking piece, and can easily operate the plate locking piece.

  In one embodiment of the present invention, the plate locking pieces are installed on both sides of the plate body.

  According to the above configuration, since the plate locking pieces are installed on both sides of the plate main body, by rotating the plate locking pieces on both sides in the locking direction, the locking position of the opening / closing body, that is, opening and closing The locking position of the body can be changed.

  Therefore, not only for crime prevention, but for the purpose of indoor ventilation, for example, when it is desired to keep the opening and closing body slightly open and locked, the other plate locking different from the locking plate at the locking position The opening / closing body can be locked at a desired position by rotating the piece in the locking direction.

  In one embodiment of the present invention, a plurality of the plate locking pieces and the plate main body are alternately installed, and each plate locking piece and the plate main body are connected by the rotating pin.

  According to the above configuration, a plurality of plate locking pieces and plate main bodies are alternately installed and connected by rotating pins, so that by rotating each plate locking piece in the locking direction, the locking position of the opening and closing body is A plurality can be set for each plate locking piece.

  Therefore, not only for crime prevention, but for example, for indoor ventilation, if you want to open and close the opening body slightly and lock it in that position, open and close the opening / closing body slightly for the entry and exit of small animals such as cats. The open / close body can be locked at a desired position, for example, when it is desired to be opened and locked.

In one embodiment of the present invention, the plate body and the plate locking piece are translucent.
According to the above configuration, since the plate body and the plate locking piece are translucent, the window locking device exposed on the indoor side of the opening and closing body can be made as inconspicuous as possible, The appearance when the apparatus is attached can be improved.
Moreover, since the window locking device is not conspicuous, it can be difficult to be detected by an intruder, and crime prevention can be improved.

In one embodiment of the present invention, a plurality of the plate locking pieces are set.
According to the above configuration, since there are a plurality of plate locking pieces, the load received from the opening and closing body when the opening and closing body is opened can be dispersed and supported by each plate locking piece. The effect of stopping) can be further enhanced.

In one embodiment of the present invention, the synthetic resin is polycarbonate.
According to the above configuration, the plate main body and the plate locking piece are made of a strong and hard-to-break synthetic resin called “polycarbonate”, so that even if the open / close body is forcibly opened in the locked state, it is damaged. The locked state can be reliably maintained.
“Polycarbonate” also has self-extinguishing properties that naturally extinguish the fire when the fire source is removed, so it can prevent the spread of fire even when used indoors as a locking device for windows. Can also be suppressed.

According to this invention, since the rotation pin serving as the rotation shaft of the plate locking piece is connected by press-fitting, the operator can operate the plate locking piece with a certain operating force when switching between unlocking and locking. If the operation is not continued, the plate locking piece cannot be rotated.
In particular, when operating from outside, it is difficult for an intruder or the like to perform an unlocking operation because the plate locking piece on the back side of the sash frame or the like must be rotated with a fingertip or the like.
In addition, since the window locking device simply switches the locking and unlocking by rotating the plate locking piece, the device itself can be made compact. Furthermore, since the plate body and the plate locking piece are formed of synthetic resin, the weight can be reduced.
Therefore, in the window locking device attached to the sliding door type opening / closing body, the crime prevention property can be further enhanced while being compact and lightweight.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
First, the first embodiment will be described with reference to FIGS. FIG. 1 is an overall perspective view of the window locking device of the present embodiment, in which (a) is an unlocked state and (b) is a locked state. 2 is a side view for explaining the operation from the unlocked state to the locked state, FIG. 3 is a side view for explaining the operation from the locked state to the unlocked state, and FIG. 4 is the state actually attached to the sash frame of the window glass. FIG.

  As shown in FIG. 1, the window locking device 1 of the present embodiment includes a flat plate-like plate body 2 made of polycarbonate, a flat plate-like plate locking piece 3 made of polycarbonate installed on the side thereof, and both. And a metal rotating pin 4 to be connected.

  The plate body 2 is formed of a horizontally long rectangular body, for example, is formed of a polycarbonate molded product having a length of 66 mm, a width of 25 mm, and a thickness of 4 mm. And the back surface 2a (sash frame mounting surface) is provided with a double-sided pressure-sensitive adhesive tape 5 (shown by a broken line), and the double-sided pressure-sensitive adhesive tape 5 is attached to the sash frame.

The plate locking piece 3 is also formed of a vertically long rectangular body, and is formed of, for example, a polycarbonate molded product having a length of 18 mm, a width of 25 mm, and a thickness of 4 mm.
For this reason, when this plate latching piece 3 is made into an unlocked state (a), the plate main body 2 and the plate latching piece 3 look like one plate body on appearance, and appearance can be improved.

  The rotating pin 4 is formed of a cylindrical metal pin, for example, a pin having a length of 28 mm and a thickness of 2 mm. The side end portions 2b and 3a between the plate body 2 and the plate locking piece 3 It arrange | positions so that it may extend in the same direction as the longitudinal direction of the plate main body 2. FIG. The rotation pin 4 is press-fitted and fixed to the plate body 2 and the plate locking piece 3 to connect the plate body 2 and the plate locking piece 3.

  The plate locking piece 3 is configured to rotate between the unlocked state (a) and the locked state (b) about the rotating pin 4 as a rotation axis. However, since the rotary pin 4 is connected to the plate body 2 by press-fitting and fixing, a sliding resistance is always received from the rotary pin 4 when the rotary operation is performed.

  Therefore, in order to rotate the plate locking piece 3, it is necessary to continuously apply an operating force of a predetermined value or more against the sliding resistance to the plate locking piece 3.

  Therefore, the operator cannot operate the plate locking piece 3 with one touch, and switches between the unlocked state and the locked state by continuously applying an operation force of a predetermined value or more.

Further, an operation inclined surface 31 having a predetermined inclination angle is provided on the side surface of the rotation side end 3b of the plate locking piece 3 (see FIG. 2).
Specifically, as shown in FIG. 2, an operation inclined surface 31 that forms an acute angle α with the front surface 3 c (inner side surface) of the plate locking piece 3 is formed. For example, it is formed with α = 70 °. On the other hand, as shown in FIG. 3, the operation inclined surface 31 forms an obtuse angle β with the back surface 3 d when viewed from the back surface 3 d (outside surface) of the plate locking piece 3. For example, β = 110 °.

  In this way, by setting the angle formed with the front surface 3c to an acute angle α, an operator from the room can easily apply the fingertip H (see the broken line in FIG. 2) to the operation inclined surface 31, and the plate locking piece 3 is opened. The operation from the locked state to the locked state can be easily performed.

  On the other hand, by setting the angle formed with the back surface 3d to be an acute angle β, an operator (intruder) from outside can operate the fingertip H ′ (see the broken line in FIG. 3) even when trying to operate the plate locking piece 3. It becomes difficult to hang on the surface 31, and it becomes difficult to operate the plate locking piece 3 from the locked state to the unlocked state.

Thus, by providing the operation inclined surface 31 at the rotation side end 3b of the plate locking piece 3, the operability of operating from the unlocked state to the locked state can be improved, and conversely the locked state By making the operability for operating from an open state to an unlocked state difficult, it is possible to improve crime prevention.
2 and 3, reference numeral 11 denotes a window glass sash frame, and 12 denotes a glass body.

FIG. 4 shows a state in which the window locking device 1 of this embodiment is actually attached to the sash frame 11 of the window glass 10.

Further, in this embodiment, the operation inclined surface 31 of the rotation side end 3b of the plate locking piece 3 is inclined so as to form an acute angle α with the front surface 3c.
According to this configuration, when the operator rotates the plate locking piece 3 in the locking direction from the front surface 3c side, that is, from the indoor side, the fingertip is easily caught on the rotation side end 3b of the plate locking piece 3, It becomes easy to rotate the plate locking piece 3. On the other hand, when the plate locking piece 3 is rotated in the unlocking direction, the operation inclined surface 31 forms an obtuse angle β with the back surface 3d. It becomes difficult to rotate the piece 3.
Therefore, it is possible to provide a locking device that is easy to operate in the locking direction and difficult to operate in the unlocking direction, making the operability in the unlocking direction difficult while enhancing the operability in the locking direction. Security can be improved.

In this embodiment, the plate body 2 and the plate locking piece 3 are translucent.
According to this configuration, the window locking device 1 exposed on the indoor side of the sash frame 11 can be made as inconspicuous as possible, and the appearance when the window locking device 1 is attached is improved. Can do.
Moreover, since the window locking device 1 is not conspicuous, it can be hardly detected by an intruder, and the crime prevention property can be improved.

In this embodiment, the plate body 2 and the plate locking piece 3 are formed of polycarbonate.
According to this configuration, even if the sash frame 11 is forcibly opened in the locked state by forming the plate body 2 and the plate locking piece 3 with a strong and difficult-to-break synthetic resin called “polycarbonate”. Thus, there is no risk of damage due to impact or the like, and the locked state can be reliably maintained.
“Polycarbonate” also has self-extinguishing properties that naturally extinguish the fire when the fire source is removed, so it can prevent the spread of fire even when used indoors as a locking device for windows. Can also be suppressed.

  Note that the color of the plate locking piece 103 is not particularly limited to red as long as it is a color different from that of the plate body 2, and may be black, yellow, white, or the like.

  Next, a third embodiment will be described with reference to FIG. FIG. 7 is an overall perspective view of the window locking device of this embodiment, in which (a) shows an unlocked state and (b) shows a locked state. In this embodiment as well, components similar to those in the above-described embodiment are denoted by reference numerals and description thereof is omitted.

  In the window locking device 201 of this embodiment, a second plate locking piece 203 is installed on the opposite side of the plate body 2 in addition to the normal plate locking piece 103. That is, the plate locking pieces 103 and 203 are installed on both sides of the plate body 2.

  The added second plate locking piece 203 is also formed of a vertically long rectangular body like the normal plate locking piece 103. For example, the second plate locking piece 203 is formed of a polycarbonate molded product having a length of 18 mm, a width of 20 mm, and a thickness of 4 mm. Yes.

  The second plate locking piece 203 is also configured to rotate between the unlocked state and the locked state by the rotary pin 4 that is press-fitted and fixed.

  Thus, by having the two plate locking pieces 103 and 203 on both sides of one plate body 2, in this embodiment, the locking position of the window glass 20 (see FIG. 4) is set to two. Can do. That is, at the position of the normal plate locking piece 103, as in the first embodiment, the window glass 20 (see FIG. 4) is locked at the position where the window glass 20 (see FIG. 4) is closed in order to perform the crime prevention function. At the position of the piece 203, the window glass 20 (see FIG. 4) can be locked at a slightly opened position for indoor ventilation.

  Thus, according to this embodiment, since the plate locking pieces 103 and 203 are installed on both sides of the plate body 2, the plate locking pieces 103 and 203 on both sides are rotated in the locking direction, respectively. Thus, the locking position of the window glass 20, that is, the locking position of the window glass 20 can be changed.

  Therefore, when it is desired not only to prevent crime but also to open the window glass 20 slightly and keep it locked at that position for indoor ventilation, for example, the other plate locking piece 103 is rotated in the locking direction. Thus, the window glass 20 can be locked at a desired position, and the function of the window locking device can be increased.

  Next, a fourth embodiment will be described with reference to FIGS. FIG. 8 is an overall perspective view of the window locking device according to this embodiment, as in FIG. 7, where (a) shows an unlocked state and (b) shows a locked state. FIG. 9 is a diagram schematically showing the use state of this embodiment including the window glass, in which (a) is an unlocked state, (b) is a first locked state, (c) is a second locked state, (d ) Is the third locked state, with the upper part being the outdoor and the lower part being the indoor. In this embodiment as well, components similar to those in the above-described embodiment are denoted by reference numerals and description thereof is omitted.

  In the window locking device 301 of this embodiment, two plate bodies made of polycarbonate (first plate body 302, second plate body 312) and three plate locking pieces (first plate locking piece 303, second plate). The locking pieces 313 and the third plate locking pieces 323) are arranged in a row so as to be alternately arranged in order, and the plate main bodies 302 and 312 and the plate locking pieces 303, 313 and 323 are press-fitted and fixed. It is configured by connecting with metal rotating pins 4 and 104.

  The central plate locking piece 313 and the plate bodies 302 and 312 on both sides thereof are connected by a single long rotating pin 104. Thereby, the rigidity of the window locking device 301 whose strength is weakened by increasing the length is compensated.

  In this embodiment, as shown in FIG. 9, the locking position of the window glass 20 can be changed by changing the rotational position of each plate locking piece 303, 313, 323 between the locked state and the unlocked state. ing.

First, in the unlocked state of (a), all the plate locking pieces 303, 313 and 323 are in a locked state so that the window glass 20 can be freely opened and closed.
In the first locked state of (b), the first plate locking piece 303 located on the most window glass 20 side is in the locked state, and the other plate locking pieces 313 and 323 are in the unlocked state. In this state, since the window glass 20 is locked at a position where the window glass 20 is almost completely closed, it is possible to improve crime prevention as an auxiliary lock.
In the second locked state of (c), the second plate locking piece 313 at the center position is in the locked state, and the other plate locking pieces 303 and 323 are in the unlocked state. In this state, since the window glass 20 is locked at a slightly opened position, an opening length L1 (for example, about 60 mm) enough to take in outside air can be secured, and indoor ventilation can be performed.

  Finally, in the third locked state of (d), the third plate locking piece 323 at the position farthest from the one window glass 20 is set to the locked state, and the other plate locking pieces 303 and 313 are set to the unlocked state. . In this state, since the window glass 20 is locked at a slightly opened position, an opening length L2 (for example, about 140 mm) that allows a small animal such as a cat to pass through can be secured, and pets can be reared easily. .

  As described above, according to the present embodiment, the three plate locking pieces 303, 313, 323 and the two plate main bodies 302, 312 are alternately installed, and each plate locking piece 303, 313, 323 and the plate are placed. Since the main bodies 302 and 312 are connected by the rotation pins 4 and 104, each plate locking piece (first plate locking piece 303, second plate locking piece 313, and third plate locking piece 323) is rotated. In addition, three positions for locking the window glass 20 can be set.

  Therefore, not only for the purpose of crime prevention but also for indoor ventilation, if the window glass 20 is to be slightly opened and locked, or if a small animal such as a cat enters or exits, the window glass 20 is slightly opened for engagement.

  Next, a fifth embodiment and a sixth embodiment will be described with reference to FIGS. In the embodiment of FIGS. 10 and 11, the plate locking piece is composed of two parts, (a) shows the unlocked state, and (b) shows the locked state.

First, the window locking device 401 of the embodiment shown in FIG. 10 is configured by two upper and lower parts 403A and 403B when the plate locking piece 403 is viewed in the mounted state. Further, in this embodiment, one rotation pin 4 is also provided at each of the upper and lower ends. Further, for the upper and lower plate locking pieces 403A and 403B, inclined operation surfaces 31 and 31 that form an acute angle α with the front surface 3c are provided at the respective rotation side end portions 3b and 3b.
Other configurations are the same as those in the first embodiment.

According to this embodiment, the load received from the window glass 20 when the window glass 20 is opened by the rollers in which the plate locking piece 403 is composed of two parts 403A and 403B is distributed by the plate locking pieces 403A and 403B. Therefore, the locking effect (the effect of locking the window glass 20) can be further enhanced.
That is, since the load applied to each of the plate locking pieces 403A and 403B and the rotating pins 4 and 4 can be reduced, the possibility of breakage is reduced, and the locking effect as the locking device can be enhanced.

Therefore, even if the window locking device is composed of a synthetic resin other than polycarbonate, there is no risk of breakage, and the locking effect can be enhanced.
In addition, about another effect, it is the same as that of 1st embodiment.
Also in this embodiment, as indicated by the dotted line, the width of each plate locking piece 403A, 403B is shortened to identify the position of the plate locking piece 403 from the operator as in the second embodiment. The plate locking piece 403 may be easily operated.

  Next, in the window locking device 501 of the embodiment shown in FIG. 11, the plate locking piece 503 is composed of two upper and lower parts 503A and 503B, and each rotation side end 3b of the plate locking pieces 503A and 503B. , 3b are provided with overlapping step portions 531 and 531.

According to this embodiment, the plate locking pieces 503A and 503B are provided with the overlapping step portions 531 and 531. Thus, even when the plate locking piece 503 is composed of two parts, both plates in the unlocked state (a). Since there is no “gap” between the locking pieces 503A and 503B, the appearance can be improved.
Therefore, the appearance can be improved while enhancing the locking effect.
Other operational effects are the same as those of the fifth embodiment described above.
