Abstract
Description
[Technical Field]
[0001] The present invention relates to a security device for a door lock of a sliding door, and more particularly to a security device that prevents the door lock, such as a crescent lock, from being opened by breaking the glass of the sliding door. [Background technology]
[0002] A known burglary tactic involves breaking a sliding window to open the crescent lock. Potential solutions to prevent this include installing a lattice on the outside of the sliding window, providing the sliding window with a lock that offers greater security than a crescent lock, or providing the sliding window with multiple locking mechanisms. However, providing a lattice, a lock with greater security, or multiple locking mechanisms on the sliding window increases the cost of the sliding window. Furthermore, it is not easy to modify an existing sliding window with a crescent lock to provide a lattice, a lock with greater security, or multiple locking mechanisms. There is a need for a security device that can utilize the environment in which an existing sliding window with a crescent lock is installed, discourage burglars from breaking into the window, and prevent the sliding window from being broken into at all.
[0003] As an example of such a security device, a security cover for a sliding door lock disclosed in Japanese Patent Application Laid-Open No. 2005-16280 is known. This anti-theft cover for a sliding door lock is characterized by comprising a mounting plate that can be attached to the vertical frame of an indoor sliding door, and a cover plate provided at one end of the mounting plate in the width direction to conceal the sliding door lock attached to the outer surface of the vertical frame so that it cannot be seen from the outside. According to the publication, with this cover, by attaching a mounting plate to the vertical frame of an outdoor sliding door, the sliding door lock is hidden from view from the outside by a cover plate attached to one end of the mounting plate in the width direction, and the sliding door lock cannot be unlocked unless the glass of the outdoor sliding door is broken over an area wider than this cover plate. Therefore, compared to when the security cover is not attached, the area of glass that needs to be broken to unlock the sliding door lock is wider, and it is more likely that an outsider such as a thief will give up on breaking the part of the glass of the outdoor sliding door that corresponds to the lock and retreat.

[0007] As explained above, the security device of the present invention is equipped with a security device having a shielding piece as its main means for performing security functions, and by simply sliding this security device sideways, the shielding piece can cover and conceal the door lock so that it cannot be seen from the outside when locked, making it easy to operate while providing high security. Furthermore, by configuring the frame of the security device to have the same external shape as the door, shelves can be installed on other parts of the frame to display ornaments (figurines, etc.), so that it can function as a decoration for the home rather than just a security device as in the past. In order to defeat this security device, an extremely large area of glass surrounding the security device must be destroyed.Furthermore, due to the width of the plates that make up the security device frame and other components extending from the inside to the outside of the house, an intruder would have to move their arms around quite a bit to reach the door lock, which would likely discourage them from defeating the device. Furthermore, when the security device of the present invention is installed on a window or the like, it functions as a security grille, making it difficult for a suspicious person to enter the house even if the door is left unclosed or locked unless the device is destroyed. Furthermore, because the main frame of the security device of the present invention is slidable, people inside the house can open a window or the like and escape to the outdoors. Therefore, unlike fixed security bars, there is no risk of being left behind inside the house in an emergency, providing peace of mind. Furthermore, when the door is unlocked, it can be opened and closed, facilitating ventilation. Furthermore, the installation of the security device of the present invention helps prevent people from falling out of windows, etc. Furthermore, the security device of the present invention is easy to remove, so it can be installed on other windows or windows at a new location as long as the window meets the specifications. As described above, the security device of the present invention can be used safely and has extremely high security. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, a security device for use with a door according to an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, the outdoor side will sometimes be referred to as the "front" and the indoor side as the "rear." The security device 10 is equipped with a rectangular box-shaped security device 50 that, when locked, conceals the door lock K (see FIG. 3) from view from outside. The door lock K (see FIG. 3) is equipped with a lock body K1 attached to the vertical frame on the inside side of the indoor door and a lock body receiver K2 attached to the vertical frame on the inside side of the outdoor door. The sliding door W (see FIG. 4) is made up of two doors, an indoor door W1 and an outdoor door W2, which are attached inside a peripheral frame F that forms an opening connecting the indoors and the outdoors (see FIGS. 1(a), (b), and 2). The symbols G1 and G2 represent the glass panels of the indoor door W1 and the outdoor door W2, respectively. The sliding door may be a sliding door, a double sliding door, a sliding window, or a double sliding window. One of the two doors may be fixed. Specifically, the sliding door may be a window sash, a veranda sash, or the like. When the sliding door is closed, the indoor door may be located on either the right or left side of the outdoor door when viewed from the indoor side. In other words, the door lock may be installed on either the left or right side when viewed from the indoor door. In this specification, unless otherwise specified, the indoor door W1 will be described as being of a type where it is located on the right side. Therefore, the door lock K (door lock body) is located on the left side of the indoor door. A typical example of the door lock is a crescent lock.
[0010] The security device 10 comprises a frame body 12 that is placed within the frame of the peripheral frame F, and this frame body is composed of a pair of vertical side frame members 14 (one side) and 16 (the other side) that are arranged at a distance that overlaps at least a portion, and preferably most of, the exterior door W2 when viewed in the width direction, a lower horizontal frame member 18 whose both sides are attached near the lower ends of the pair of vertical side frame members, and an upper horizontal frame member 20 whose both sides are attached to the upper part of the pair of vertical side frame members.
[0011] The frame body 12 is movable in the direction of movement of the door between a functional position (see Figure 4(c)) in which one side vertical side frame member 14 is aligned with the inner vertical frame W1a of the indoor door W1 and the inner vertical frame W2a of the outdoor door W2, which are aligned in the indoor / outdoor direction when the door lock is locked, and a non-functional position (see Figures 4(a) and (b)) in which it is out of this functional position, and when the frame body is positioned in the functional position, the other side vertical side frame member is positioned on the indoor side of the outdoor door. A rail R is provided on the underside of the upper frame plate of the peripheral frame F, allowing the frame body 12 to move widthwise (the sliding direction of the sliding door), while a pulley 22 that engages with the rail R is attached to the upper surface of the upper horizontal frame member 20 of the frame body 12 (see Figure 9). Furthermore, a fastening means 24 is provided on the lower horizontal frame member 18 of the frame body 12 for fixing the security device 10 in a predetermined position. This fastening means 24 is preferably of the screw type. The reason why the security device 10 can be moved widthwise in this way is to allow it to be adjusted to the position of the door lock when the sliding door is configured with three or four doors. The rails and pulleys described above also function to prevent the frame body of the security device according to the embodiment of the present invention from coming off the peripheral frame F and tipping over or falling. The upper horizontal frame member, lower horizontal frame member, and pair of vertical side frame members of the frame body are made of wood or metal (for example, aluminum alloy used in sashes) and are each formed from plate-shaped members. Depending on the structure of the security device, the rail R and the associated pulley 22 may be omitted and a simple fitting type may be used. For consistency, the screw-type fixing means 24 must be provided.
[0012] The frame body 12 is provided with a horizontal bottom plate member 26 extending horizontally between the pair of vertical side frame members 14, 16 a predetermined distance below the door lock position when the frame body is placed within the surrounding frame F, and a horizontal top plate member 28 extending horizontally between the pair of vertical side frame members a predetermined distance above the horizontal bottom plate member, with a storage space S for the security device 50 being provided between them. The horizontal bottom plate member 26 and the horizontal top plate member 28 are made of wood or metal (for example, aluminum alloy used in sashes) in the same manner as the frame body, and are each formed as a plate-like member.
[0013] The security device 50 is roughly shaped like a rectangular box and is intended to prevent the door lock K from being seen from outside when locked. The front and rear edges of the horizontal bottom plate member 26 of the frame body 12 are provided with a front guide wall plate 30a and a rear guide wall plate 30b that guide and restrict the movement of the security device 50 between an operating position where the locked door lock is hidden from view from outside, and a non-operating position where the security device 50 is retracted from this operating position. In addition, in order to determine the movement limit of the security device 50 from the operative position to the inoperative position (determining the positioning of the security device in the inoperative position), a regulating plate material 30c of a predetermined thickness is installed on the surface of the horizontal bottom plate member 26.
[0014] The rectangular box-shaped security device 50 has a box-shaped security device frame 51, which is equipped with two side wall plate members 56, 58 spaced apart in the extension direction of the bottom plate member 26 and the top plate member 28, and a lower plate member 52 and an upper plate member 54 extending between the lower edges and upper edges of the side wall plate members. Of the two side wall plate members, the side wall plate member 56 on the one vertical side frame member side (i.e., the door lock K side) has a length such that it does not interfere with the door lock when the security device is in the operative position (see FIG. 4(c)). A strong shielding plate 60 is provided on the exterior side (inner side) of the security device frame 51 to prevent the inside of the security device frame 56 from being seen from the outside, and when the security device 50 is in the operative position, one side 60a of this shielding plate 60 fits between the glass G2 of the exterior door and the lock body receiving portion K2 attached to the inner vertical frame W2a, and is adjacent to and in contact with the inner vertical frame W2a. The strong shielding plate 60 is preferably made of a metal plate or FRP (fiber reinforced plastic) that cannot be easily destroyed by intruders.
[0015] As shown in FIG. 1(a) and other figures, the security device 10 can also be provided with display shelves 71a, 71b, etc. inside the frame 12. The lower horizontal frame member 18 that constitutes the frame 12 can itself be used as a display shelf. These display shelves 71a, 71b are designed to display figures f, etc., and the indoor or outdoor side is made of a transparent panel that can be opened or closed so that the displayed figures f, etc. can be viewed from inside or outside. These decorations, such as figures f, also serve as a psychological aid to security.
[0016] The security device 50 includes a locking mechanism 70 that secures the security device 50 in the operative position. As shown in FIG. 3, the locking mechanism 70 includes a rod-shaped locking member 72 supported by the lower plate member 52 and the upper plate member 54 of the security device frame 51 so as to be slidable in the vertical direction. The rod-shaped locking member 72 includes a locking member body 74 of a predetermined diameter, and an upper reduced-diameter portion 76 and a lower reduced-diameter portion 78 provided at the upper and lower ends of the locking member body 74 and slidably fitted in the openings 52a, 54a formed in the lower plate member 52 and the upper plate member 54. When the locking member body 74 is positioned in the lower position, the lower reduced-diameter portion 78 is fitted into a locking hole 26a formed in the surface of the horizontal bottom plate member 26 to secure the security device 50 in the operative position. Therefore, the position of the locking hole 26a is determined taking into consideration the operative position and the position of the locking member body 74 on the frame 51.
[0017] The frame 12 is preferably provided with a lighting device 80 for illuminating at least a portion of the interior of the frame, and a power source 84 for the lighting device 80. The lighting device 80 can illuminate the figure f at night, and can also serve as an interior decoration by selecting the luminous color.
[0018] 7(a) and 7(b), a shading plate 90 for privacy or shading may be provided removably on the indoor surface of the frame body 12. This shading plate 90 also provides a heat insulating effect.
[0019] Next, the movement of the security device 50 of the security device described above between the inactive position and the active position will be explained using Figures 4 and 5. It is assumed that the door lock K is already locked. The movement (sliding) of the security device 50 described below is conveniently performed by grasping the rod-shaped locking member main body 74 of the locking means 70. First, it is slid from the inoperative position (FIG. 4(a)), which is a position adjacent to the defining plate member 30c installed on the surface of the horizontal bottom plate member 26, in the direction of the arrow shown in that figure, i.e., toward the exterior door W2, to the position shown in FIGS. 4(b) and 5(c). Next, it is slid in the direction of the arrow shown in FIGS. 4(b) and 5(c), i.e., in the direction of the door lock K (to the right as viewed in the figures), to the operative position shown in FIG. 4(c), and is fixed in that position. For this fixing, the locking means 70 is used. The movement of the security device 50 from the operative position to the inoperative position is performed in the reverse order to the above.
[0020] Next, with reference to FIG. 6, the operation of removing the crime prevention device 50 from the storage space S, and ultimately from the frame body 12, will be described. First, the security device 50 is moved from the operating position to the left in the figure to the position shown in Figure 6(a) (where it contacts the regulating plate 30c). Then, it is slid in the direction of the arrow in the figure (away from the glass plate G2) to a position where it contacts the rear guide wall plate 30b. This position is the non-operating position.
[0021] Next, in this position, the security device 50 is lifted upward until it hits the top plate member 28 (see FIG. 6(b)). At this time, the bottom surface of the security device 50 is positioned above the surface of the regulating plate member 30c. From this position, the security device 50 is moved in the direction of the arrow in FIG. 6(b) until it climbs over the regulating plate member 30c. Then, the security device 50 is lowered to the position shown in FIG. 6(c).
[0022] 6(c), along the guide of the front guide wall plate 30a and the rear guide wall plate 30b, slide the security device 50 on the bottom plate member 26 to the other vertical side frame member 16 (FIG. 6(d)). Up to this position, the rear guide wall plate 30b has not extended (see FIG. 6(a) etc.) and is open, so the security device 50 can be removed from the frame body 12 by pulling it out in the direction of the arrow in FIG. 6(b) (toward the viewer in the drawing).
[0023] Because the security device of the present invention has the structure described above, breaking the security device requires breaking an extremely wide area of glass around the shielding member. Furthermore, due to the width of the plates extending inside and outside the house that form the frame that makes up the security device, an intruder would have to move their arms around quite a bit to reach the door lock, which would likely discourage the intruder from attempting to break the device. Furthermore, the security device of the present invention uses horizontal plates that also function as a display shelf for ornaments, etc., so it is not just a security measure like conventional devices, but can itself function as a decoration for the home. The display shelf can be used to display figurines, etc., and since breaking the lock requires scattering the figurines, etc., displayed on the display shelf, it is also useful from a psychological perspective as a security measure.
