Description

[Technical field]

[0001] This invention relates to a grille used for crime prevention and other purposes on "windows whose lower part reaches the floor or nearby" that are installed in a dwelling (including an apartment building) and can be opened and closed to allow residents to enter and exit between the outside of the building, such as a terrace, balcony, veranda, or garden, and the inside of the building. [Background technology]

[0002] Conventionally, in houses (including apartment buildings), storm shutters have often been installed for security purposes on "windows whose lower parts reach the floor or nearby areas" (see, for example, the window frame 20a and window 20 in Figure 5) that are openable and closable to allow residents to enter and exit between the inside of the building and the outdoors, such as a terrace, balcony, veranda, or garden (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3198132 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the past, in order to install shutters, space was required to place a storage section to keep the shutters in (a storage section provided on the side of the shutters), and if such space was not available, they could not be installed; installing shutters after a house had been built required large construction costs; if the shutters were closed at night, they needed to be opened the next morning to let in the light from outside, but this opening and closing process was extremely cumbersome; closing the shutters every time one went out during the day or when there was a strong wind was troublesome, so it was not uncommon for this to be avoided, but if the shutters were left open when one went out or when there was a strong wind, there were problems such as theft prevention when one went out and the inability to prevent flying objects from breaking the windows in a strong wind.

[0005] The present invention has been made in response to such problems in the prior art, and aims to provide a sliding grille for security, etc., for entrance windows in homes (including apartment buildings) with "entrance windows whose lower parts reach the floor or close to it" that are installed so that they can be opened and closed to allow people to enter and exit between the inside of the building and the outdoors, such as on a terrace, balcony, veranda, or garden, even when there is no space to install a shutter storage unit, and which can easily provide security, etc., for entrance windows as a retrofit at low cost and with ease even after the home has been built, which can easily provide both lighting and security regardless of whether it is at night or during the day, and which can ensure security when going out without being forced to do the troublesome work of closing the shutters every time one goes out during the day or when there is a strong wind, as in the past, and which can prevent flying objects from breaking the window in strong winds. [Means for solving the problem]

[0006] The sliding grille for security purposes for entrance windows according to the present invention is a grille for security purposes that is installed in a residence (including an apartment building) on ​​the outside of an "entrance window whose lower part reaches the floor or near it" that is installed so as to be openable and closable to allow people to enter and exit between the inside of the building and the outdoors such as a terrace, balcony, veranda or garden, and the like. The grille is equipped with a guide rail section that is arranged on the outside of the entrance window and fixed to the window frame or the exterior wall of the building so as to face at least the upper and lower sides of the entrance window, respectively, a plurality of vertical grilles that are arranged vertically between the upper and lower guide rail sections, and support sections that support at least some of the vertical grilles so that the upper and lower ends of the vertical grilles are opposite to the upper and lower guide rail sections, respectively, and that support at least some of the vertical grilles so that they can move laterally along the guide rail sections.

[0007] In addition, in the sliding grille for security purposes, etc., of an entrance / exit window according to the present invention, the upper and lower guide rail portions may be part of an outer frame arranged approximately opposite and close to the outer periphery of the entrance / exit window.

[0008] Furthermore, in such a sliding grille for security purposes for an entrance / exit window according to the present invention, adjacent vertical grilles located to the right or left of the center among the multiple vertical grilles may be connected to each other by a string-like member such as a wire of a predetermined length or other connecting member.

[0009] Furthermore, in such a sliding grille for security purposes, etc., on an entrance / exit window according to the present invention, the vertical grille located at the right end and / or left end of the multiple vertical grilles may be fixed to the window frame of the entrance / exit window or the exterior wall of the building (including each of the guide rail portions) so as not to move.

[0010] In addition, in the sliding grille for security purposes, etc., on an entrance / exit window according to the present invention, the two vertical grilles located in the middle of the multiple vertical grilles may be provided on the inside of the building with latches that secure the two vertical grilles in a connected state.

[0011] Furthermore, in the sliding grille for security purposes for entrance and exit windows according to the present invention, the two central vertical bars among the multiple vertical bars may be provided on the inside of the building with latches that secure the two vertical bars in a connected state, and the latches may be provided with a key to prevent the latches from being opened. Effect of the Invention

[0012] According to the sliding grille for security, etc. on entrance windows of the present invention, at least some of the vertical grilles are configured to be movable horizontally by the upper and lower guide rail portions and the support portions, and are installed on the entrance windows (entrance windows whose lower portions reach the floor or near it) of a residence (including an apartment building). Therefore, security measures can be easily implemented even if there is no space to install a storm shutter storage portion. Even after the house has been built, security measures for entrance windows can be implemented at low cost and easily as an afterthought. It is possible to easily achieve both lighting and security regardless of whether it is at night or during the day. Security can be ensured when going out without being forced to go through the cumbersome task of closing the shutters every time one goes out during the day or when there is a strong wind, as in the past, and it is also possible to prevent objects flying into the window in strong winds from breaking the window.

[0013] In addition, in this device, when the upper and lower guide rail portions are configured as part of the outer frame arranged to face and be close to almost the entire entrance / exit window, it becomes easy to firmly install the guide rail portions on the exterior wall of the building.

[0014] In addition, in the present invention, if adjacent vertical bars located to the right or left of the center among the multiple vertical bars are connected to each other by string-like members such as wires of a certain length or other connecting members, when the multiple vertical bars are moved toward the center for crime prevention, etc., the spacing between each vertical bar in the grille will be kept approximately equal by the string-like members such as wires or other connecting members.

[0015] Furthermore, in the present invention, if the vertical bars located at the right end and / or left end of the multiple vertical bars are fixed to the window frame of the entrance / exit window or the exterior wall of the building (including each of the guide rail portions), even if some of the multiple vertical bars are moved left or right, the positions of the vertical bars at the right end and / or left end remain fixed, thereby stabilizing the positions of each of the vertical bars.

[0016] Furthermore, in this invention, if the two central vertical bars among the multiple vertical bars are provided with latches on the inside of the building to secure the two vertical bars in a connected state, when the multiple vertical bars are moved toward the center for crime prevention, etc., the overall position of the multiple vertical bars can be fixed in that state.

[0017] Furthermore, in this invention, if the two central vertical bars among the multiple vertical bars are provided on the inside of the building with latches that secure the two vertical bars in their connected state and a key that prevents the latches from being opened, then when the multiple vertical bars are moved toward the center for crime prevention purposes, the overall position of the multiple vertical bars can be fixed in that state and they cannot be opened from the outside.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] [Embodiment 1] Hereinafter, a first embodiment of the present invention will be described. Fig. 1 is a perspective view showing a sliding grille according to the first embodiment, in which vertical bars are fixed at approximately equal intervals over the entire window to prevent people from entering or exiting through the window, Fig. 2 is a perspective view showing the sliding grille when the vertical bars are moved so that people can enter or exit through the window in the first embodiment, and Fig. 3 is a perspective view showing the state in which the vertical bars 2 are attached to the rod-shaped guide rails 1a and 1b in the first embodiment, from the inside of the building.

[0020] In Figures 1 to 3, reference numeral 20 denotes an entrance window through which residents can enter and exit between the inside of a building and the outdoors (garden), and is a "sliding door type French window (a type of entrance window) in which, unlike a waist-high window, the bottom edge of the window extends to the floor" and is made of window glass fixed inside a window frame 20a made of a metal such as aluminum, 1a and 1b denote rod-shaped guide rails for a grille that are installed and fixed to the exterior wall of a building so as to roughly face the upper and lower parts of the entrance window 20, respectively, and are guide rails made of metal such as aluminum, stainless steel or iron, or made of resin, and 2 denotes a number of vertical grilles that are slidably supported by the guide rails 1a and 1b.

[0021] In the present embodiment 1, as shown in Fig. 3, the upper end 2a and the lower end 2b of each vertical lattice 2 are provided with bushes (bearings / supports for each vertical lattice 2) 3a, 3b, respectively, and the guide rails 1a, 1b are inserted into the bushes 3a, 3b. As a result, each vertical lattice 2 is supported so as to be able to slide in the left-right direction along the guide rails 1a, 1b.

[0022] As shown in FIG. 3, in this embodiment 1, the two vertical lattices 2 located at both the left and right ends of the plurality of vertical lattices 2 are fixed to the respective guide rails 1a, 1b (fixed so as not to move in the left-right direction) by, for example, known fixing brackets 4a, 4b.

[0023] In addition, in this embodiment 1, the two vertical lattices 2 located in the center in the left-right direction among the multiple vertical lattices 2 each have handles 5a, 5b fixed to approximately the center in the up-down direction, which are used by the resident (user) to slide each vertical lattice 2 left and right.

[0024] In the first embodiment, a known latch lock 6 is provided in the vicinity of the handles 5a, 5b of two vertical bars 2 located at the center in the left-right direction among the plurality of vertical bars 2. The latch lock 6 is provided with a known key 7 (for example, a key that is unlocked with a PIN number) to prevent the latch lock 6 from being unlocked illegally.

[0025] In the present embodiment 1, magnets 8a, 8b that attract each other are provided at one or more locations on the opposing surfaces of two vertical lattices 2 located at the center in the left-right direction among the plurality of vertical lattices 2. Furthermore, in the present embodiment 1, fixing brackets 9a, 9b for firmly fixing the positions of the two vertical lattices 2 to each other are provided at the upper and lower ends of the two vertical lattices 2 located at the center in the left-right direction among the plurality of vertical lattices 2 (used when it is desired to firmly fix the plurality of vertical lattices 2 without moving them to prevent intrusion, etc.).

[0026] In the first embodiment, 10a and 10b are wires fixed to the upper and lower ends of the vertical lattices 2 located to the right of the center in the figure. The wires 10a and 10b connect the adjacent vertical lattices 2 to each other with a predetermined length so that the adjacent vertical lattices 2 to the right of the center among the vertical lattices 2 can maintain a predetermined equal interval. As a result, when each vertical lattice 2 located to the right of the center is slid toward the center by the user, the wires 10a and 10b are in a linearly taut state, and each of the vertical lattices 2 is fixed to each other with an equal interval between adjacent ones. On the other hand, when each vertical lattice 2 located to the right of the center is moved to the right in a direction away from the center, the interval between adjacent ones of the vertical lattices 2 becomes narrower, and as a result, the wires 10a and 10b are in a relaxed and curved state. Note that the wires shown in FIG. 3 are omitted in FIGS. 1 and 2.

[0027] In the first embodiment, 11a and 11b are wires fixed to the upper and lower ends of the vertical lattices 2 located to the left of the center in the figure. The wires 11a and 11b connect the adjacent vertical lattices 2 to the right of the center of the vertical lattices 2 with a predetermined length so that the adjacent vertical lattices 2 to the right of the center among the vertical lattices 2 can maintain a predetermined equal interval. As a result, when each vertical lattice 2 located to the left of the center is slid toward the center by the user, the wires 11a and 11b are in a linearly taut state, and each of the vertical lattices 2 is fixed to each other with the adjacent ones spaced equally apart. On the other hand, when each vertical lattice 2 located to the left of the center is moved leftward away from the center, the interval between the adjacent ones of the vertical lattices 2 becomes narrower, and as a result, the wires 11a and 12b are in a relaxed and curved state.

[0028] Next, the operation of the present embodiment 1 will be described. First, if a user (resident) wants to prevent a suspicious person from entering the building through an entrance window, it is necessary to make each vertical lattice 2 of the grille according to the present embodiment 1 face the entrance window. In this case, the user grasps the handles 5a and 5b of the two vertical lattices 2 on the left and right sides of the center side and slides the two vertical lattices 2 located on the center side so that they approach each other. As a result, the wires 10a and 10b and the wires 11a and 11b are each taut in a straight line, and the intervals between the adjacent vertical lattices 2 become equal. After that, the user (resident) connects and fixes the two vertical lattices 2 located on the center side to each other with the latch 6, and further locks the latch 6 with the key 7 so that it cannot be opened from the outside of the door. Furthermore, if necessary, the upper end portions 2a and the lower end portions 2b of the two vertical lattices 2 located on the center side are fixed by the fixing brackets 9a and 9b, respectively.

[0029] Next, when a user (resident) wants to use the entrance window to enter and exit between the outside and the room, it is necessary to make sure that each vertical lattice 2 of the lattice according to the first embodiment does not face at least a significant portion of the entrance window. In this case, the user first removes the fixing brackets 9a, 9b if the upper ends 2a and the lower ends 2b of the two vertical lattices 2 located on the center side are fixed by the fixing brackets 9a, 9b, and then opens the lock 7 to release the latch 6. After that, the user takes at least one of the handles 5a and 5b of the two vertical lattices on the left and right sides of the center side and slides the two vertical lattices 2 located on the center side so that they move away from each other. As a result, the interval between the vertical lattices 2 on at least one side to the right and left of the center becomes narrow, and at least one of the wires 10a and 10b and the wires 11a and 11b becomes relaxed and curved. As a result, at least one of the vertical bars 2 on the right and left side of the center is moved to the side edge of the entrance window, so that at least the central part of the entrance window or its nearby part is not faced by the vertical bars 2, allowing users (residents) to enter and exit from outside to inside or from inside to outside.

[0030] As described above, according to the sliding grille of this embodiment 1, at least some of the vertical grilles 2 among the multiple vertical grilles 2 are configured to be movable laterally by the upper and lower guide rails 1a, 1b and the bushes 3a, 3b, so that the grille can be easily installed even when there is no space to install a storm shutter storage section. Even after the house is built, measures for crime prevention for entrance and exit windows can be retrofitted at low cost and easily. It is possible to easily achieve both lighting and crime prevention regardless of whether it is at night or during the day. Crime prevention when going out can be ensured without being forced to go through the troublesome task of closing the storm shutters every time one goes out during the day or when there is a strong wind, as in the past, and it is also possible to prevent flying objects from breaking the window in strong winds.

[0031] Furthermore, in this embodiment 1, adjacent vertical lattices 2 on the right or left side of the center among the multiple vertical lattices 2 are connected to each other by wires 10a, 10b and 11a, 11b of predetermined lengths, respectively. Therefore, when the multiple vertical lattices 2 are moved toward the center for crime prevention or the like, the spacing between each of the vertical lattices 2 in the surface lattice is kept approximately equal due to the lengths of the wires 10a, 10b and 11a, 11b.

[0032] Furthermore, in this embodiment 1, the right and / or left end vertical lattice pieces 2 among the plurality of vertical lattices 2 are fixed to the exterior wall of the building (including the guide rails 1a, 1b). Therefore, even if some of the plurality of vertical lattices 2 are moved left or right, the position of the right and / or left end vertical lattice pieces 2 remains fixed, thereby stabilizing the position of each vertical lattice piece 2.

[0033] Furthermore, in this embodiment 1, the two central vertical bars 2 among the plurality of vertical bars 2 are provided on the inside of the building with latches 6 that fix the two vertical bars 2 in a connected state. Therefore, when the plurality of vertical bars 2 are moved toward the center for crime prevention or the like, the overall position of the plurality of vertical bars 2 can be fixed in that state by the latches 6.

[0034] Furthermore, in this embodiment 1, not only are the two central vertical bars 2 among the plurality of vertical bars 2 provided with latches 6 on the inside of the building to fix the two vertical bars 2 in a connected state, but also the latches 6 are provided with keys 7 to prevent the latches 6 from being opened from the outside. Therefore, when the plurality of vertical bars are moved to the center for crime prevention or the like, the entire position of the plurality of vertical bars 2 can be fixed in that state by the latches 6 and key 7, so that they cannot be moved reliably from the outside.

[0035] [Embodiment 2] Next, FIG. 4 is a perspective view showing a state in which a sliding grille for security purposes, etc., according to embodiment 2 of the present invention is installed in a conventional sweep window (a type of entry / exit window).

[0036] In Figure 4, reference numeral 20 denotes an entrance window that allows residents to enter and exit between the inside of the building and the outdoors (garden), and is a "sliding-door type French window in which, unlike a waist-high window, the bottom edge of the window extends to the floor" consisting of window glass installed inside a window frame 20a made of a metal such as aluminum, 21 denotes a grille outer frame made of a metal such as aluminum, stainless steel or iron, or a resin, which is installed on the outside of the window frame 20a of the entrance window 20 so as to approximately face it, and is an approximately rectangular grille outer frame when viewed from the front, and 22 denotes a number of vertical grilles supported by the upper and lower parts of the grille outer frame 11.

[0037] The upper and lower ends of each of the vertical lattices 22 are supported so as to be movable in the left-right direction in the figure by a convex rail portion (or a concave groove) formed on the upper and lower parts of the outer frame 21 for the lattice. The configuration for supporting each of the vertical lattices 22 so as to be movable in the left-right direction in the figure can be substantially the same as that of the first embodiment, for example, a configuration in which the upper and lower ends of each of the vertical lattices 22 are fitted into a convex rail portion (or a concave groove portion), but a detailed description thereof will be omitted here. Furthermore, with such a configuration, the second embodiment achieves substantially the same effects as the first embodiment. Furthermore, in the second embodiment, the guide rail portion for moving each of the vertical lattices 22 in the lateral direction (left-right direction) is configured as a part of the outer frame 21 arranged so as to face and be close to substantially the entirety of the entrance window (as each of the upper and lower parts of the outer frame 21), so that each of the guide rail portions can be easily and firmly installed on the outer wall side of the building.

[0038] Although the embodiments of the present invention have been described above, the present invention is not limited to these, and various modifications and changes are possible. For example, in the first embodiment, the wires 10a, 10b and 11a, 11b of a predetermined length are used to connect the vertical lattices on the right and left sides of the center of the vertical lattices 2, respectively, but in the present invention, other connecting members, for example, other string-like members (such as chains), may be used instead of the wires 10a, 10b, 11a, 11b of the predetermined length. Furthermore, the guide rails 1a, 1b in the first embodiment may be slide rails. [Explanation of symbols]
