Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Use The present invention relates to a window lattice that can be opened and closed as needed.

(B) Conventional Technology As is well known, the surface lattice for windows is required to have a function of ensuring daylight and ventilation to the room and a crime prevention function of preventing a suspicious person from entering the room. ing. for that reason,
Conventionally, the area lattice is often fixed to the window frame,
Functions that can be opened and closed as needed were not so strongly required.

(C) Issues to be solved by the invention By the way, in order to deal with an emergency situation such as a fire, it is necessary to open a window to which a plane lattice is attached so that people can enter and leave the room and carry in household items. Is extremely beneficial and increases safety in an emergency. However, the conventional window lattice has a structure in which the operation of opening the window to open the window cannot be performed in order to secure the crime prevention function as described above, and the window lattice can be opened in an emergency. I couldn't get in or out of the window or bring in household items through the window.

The present invention has been made in view of the above circumstances, and by allowing the surface lattice to be opened as needed in an emergency, etc., despite the fact that the security function can be reliably exerted in normal times. An object of the present invention is to provide a window lattice which has not only the crime prevention function originally required for the lattice but also the function of opening the window in an emergency.

(D) Means for Solving the Problems A window lattice of the present invention is a window lattice having a lattice surface facing a window surface of a building, in which an axis parallel to one side of the lattice surface is centered. A support member that rotatably supports the lattice surface, a stopper that regulates the rotation of the lattice surface when the lattice surface is in a closed state parallel to the window surface, and a rotation of the lattice surface that is regulated by the stopper. A release mechanism that releases the restriction by operating an operation member exposed on the inner side of the window surface, a ring body that rotates around the shaft together with the lattice surface and forms recesses at a plurality of positions on the peripheral surface, and a ring surface Part is a claw body that is made to come into contact with and separate from the peripheral surface of the wheel body while being biased in a direction in which one end contacts the peripheral surface of the wheel body, and the other end is a claw body exposed to the window surface side. One end is formed on the circumferential surface of the ring when the surface is at a predetermined opening angle with respect to the window surface A lock member that selectively fits into one of the recesses formed therein, and a lock member that restricts rotation of the ring body in the closing direction when the nail body fits into the recess. To do.

(E) Action According to the window lattice of this structure, the rotation of the lattice surface is restricted by the stopper in the normal state, and the lattice surface is kept parallel to the window surface. Therefore, the crime prevention function, the daylighting property, and the ventilation property by the surface lattice are secured. Further, when the operation member is operated from the inside of the window surface to release the rotation restriction of the lattice surface by the stopper, the lattice surface becomes rotatable about the axis of the support member. Therefore, the window can be opened by pushing the lattice surface outward. At this time, when the lattice surface rotates about the axis and forms a predetermined opening angle with respect to the window surface, one end of the claw body provided on a part of the window surface becomes the circumferential surface of the ring body. It fits in the formed recess, and the rotation of the lattice surface in the closing direction is restricted together with the ring body. Therefore, when the lattice circle is rotated from the window surface by a predetermined opening angle or more, the open state of the lattice surface is held by the lock mechanism including the ring body and the claw body.

(F) Embodiments FIG. 1 is an enlarged side view of an essential part of a window lattice according to an embodiment of the present invention, and FIG. 2 is a cross-sectional plan view of the window lattice described above.

Reference numeral 1 denotes a surface lattice, which is a plurality of frame members 13 extending in the up-and-down direction arranged between the upper horizontal rails 11 and the lower horizontal rails 12 in parallel in the horizontal direction at intervals. The gap between them secures daylighting and ventilation. Further, the frame member 13 also functions as a lattice that prevents a suspicious person from entering. The frame members 13 may be arranged side by side in a vertically spaced manner.

Reference numeral 4 denotes a support member, a bracket 41 protruding from the upper horizontal rail 11, a horizontal shaft 42 provided on the bracket 41, and a mounting bracket.
It consists of 43 and. The support members 4 are provided at both left and right ends of the upper horizontal rail 11, and the horizontal axis 42 is formed by the lattice surface of the surface lattice 1, that is, the upper horizontal rail 11, the lower horizontal rail 12, and the frame member 13. It is set parallel to one side (the upper side in this embodiment) of the surface on which the horizontal axis 42 is connected to the upper part of the window frame via the mounting bracket 43. Therefore, the lattice plane is rotatably attached to the window frame 2 about the horizontal axis 42.

Reference numeral 5 denotes a lock member, which is a ring body 51 fixed to the horizontal shaft 42.
And a claw body 52 corresponding to the ring body 51, and a spring 53 that constantly biases the claw body 52 toward the ring body 51 side. A saw-toothed concavo-convex portion 54 is formed on a part of the outer periphery of the ring body 51. When the surface lattice 1 is rotated outwardly about the horizontal axis 42 as shown by the phantom line in FIG. 6 and the ring body 51 is rotated in the arrow X direction in FIG. Convex portion 54 of uneven portion 54
In contrast to overcoming a, the claw body 52 is
Even if the ring body 51 tries to rotate in the arrow Y direction due to the weight of the surface lattice 1 when it is fitted in the 4b, the claw body 52 is engaged with the convex portion 54a so as not to rotate. Has become. Therefore, when the surface lattice 1 is rotated outward about the horizontal axis 42 to open it, the opening angle of the surface lattice 1 is determined by which concave portion 54b of the uneven surface 54 of the ring 51 the claw body 52 meshes with.

In FIG. 2, 6 is a stopper. The stopper 6 is composed of rods provided at both left and right ends of the lower horizontal rail 12, and is pushed back and forth between the inside and the outside of the lower horizontal rail 12 by the action of a release mechanism 7 described later. is there. Then, when the lattice plane of the surface lattice 1 is parallel to the window surface 3, that is, when the surface lattice 1 is closed, the stopper 6 projects from the lower horizontal crosspiece 12, and the stoppers 6 and A hole where the stopper 6 is formed in the window frame 2 as shown.
It fits into 21 and regulates the rotation of the lattice plane. Therefore, in this state, the stopper 6 holds the surface lattice 1 on the window frame 2 so as not to open it.

The release mechanism 7 is the first one housed in the lower cross rail 12 of the surface lattice 1.
The link mechanism 71 and the second link mechanism 74 accommodated in both the frame bodies 72 and 73 provided in the window frame 2 are provided.

As shown in FIGS. 2 and 4, the first link mechanism 71 is one in which the links 71c and 71c are connected via two pins 71b and 71b at two positions displaced by 180 degrees on the disc 71a. Is connected to the stopper 6 on one side, and the link 71c on the other side is connected to the stopper 6 on the other side via a connecting member 75.
The connecting member 75 has a turnbuckle 75a. Also,
An engaging member 77 having a square hole 76 is fixed to the center of the disc 71a as shown in FIG. As shown in FIG. 3, the second link mechanism 74 includes a pair of discs 78 and 79, and two parallel links 80.
The links 80a and 80a connect the rotation of the disk 78 on one side to the disk 79 on the other side. Further, as shown in FIG. 5, a connecting rod 81 having a square tip end is fixed to the center of the disk 79 on the other side, and when the surface lattice 1 is closed, the connecting rod 81 shown in FIGS. The engaging member 7 in which the rectangular tip portion 81a of the connecting rod 81 is fixed to the disc 71a of the first link mechanism 71 as described above.
The connection rod 81 and the engaging member 77 are fitted in the square hole 76 of the shaft 7 to engage with each other in the rotational direction thereof.

Reference numeral 9 denotes an operation member, which includes a handle 91 and an operation shaft 92 connected to the handle 91, and the operation shaft 92 is the second link mechanism.
It is fixed to the center of a disk 78 on one side of 74. Therefore, when the handle 91 is rotated, the disc 78 on one side rotates in the same direction as the handle 91 by the same angle, and the rotation is transmitted to the disc 79 on the other side. The operation member 9 is exposed inside the window surface 3 so that the handle 91 can be operated from the indoor side.

In such a surface lattice 1, when the lattice surface is parallel to the window surface 3, the stopper 6 is formed in the window frame 2 by protruding from the lower horizontal rail 12 as shown in FIGS. 2 and 4. When it is fitted in 21, the rotation of the lattice plane is restricted thereby, and the plane lattice 1 is held by the window frame 2 so as not to open.
This is a normal state, and when such a surface lattice 1 is held by the window frame 2, the surface lattice cannot be opened from the outside. Therefore, the window is closed by the surface lattice 1, and a reliable crime prevention function is achieved.

On the other hand, when the handle 91 of the operation member 9 is rotationally operated from the room, the rotation of the handle 91 is transmitted from the second link mechanism 74 to the first link mechanism 71, and the action of the second link mechanism 71 causes the stopper 6 to move. It goes out from the hole portion 21 and goes into the lower cross rail 12. As a result, the restriction on the rotation of the lattice plane by the stopper 6 is released. After such a release state,
When the surface lattice 1 is pushed outward, the rectangular tip portion 81a of the connecting rod 81 comes out from the square hole 76 of the engaging member 77 to separate the connecting rod 81 and the engaging member 77, and at the same time, the surface lattice 1 is moved horizontally. The claw body 52 fits into any one of the concave portions 54b of the concavo-convex portion 54 of the wheel body 51 as the claw body 52 rotates outward about the shaft 42. Therefore, even after the hand is released from the area grating 1, the area grating 1 is held at the opening angle at that time and the window is opened.
The opening angle of the surface lattice 1 at this time is determined by which concave portion 54b of the concave-convex portion 54 the claw body 52 fits into.

When the surface lattice 1 that has been opened once is closed, the operating portion 56 extending to the rear of the claw body 52 may be pulled down by hand to separate the claw body 52 from the recess 54b. After closing the door, rotate the handle 91 to move the stopper 6 to the window frame 2
If fitted in the hole 21 of the, the rotation of the lattice plane is restricted by the stopper 6, and the crime prevention function of the surface lattice is fulfilled.

In this embodiment, the horizontal axis 42 parallel to the upper side of the lattice surface is described as the axis parallel to one side of the lattice surface, but the axis is defined as the vertical axis parallel to the left side or the right side of the lattice surface. The grid may be opened and closed laterally.

(G) Effect of the Invention As described above, according to the present invention, it is possible to exert a reliable crime prevention function on the surface lattice by restricting the rotation of the lattice surface by the stopper. In addition, by operating the operating member from the room and releasing the rotation restriction of the lattice plane by the stopper, the lattice plane can be opened and the window can be opened. It has the convenience of being able to carry in and out tools. Furthermore, when the lattice surface is opened from the window surface at a predetermined opening angle or more, the lock mechanism keeps the lattice surface in the opened state, so that people and objects can be quickly put in and taken out in an emergency. Further, the lock mechanism is a ring body concentrically provided with respect to an axis parallel to one side of the lattice plane,
Since it is composed of the claw body attached to the window surface, the member for holding the open state of the lattice surface is not exposed between the lattice surface and the window surface, and people and things can be put in and taken out. You can easily. Further, the lock member can be easily released from the room by operating the other end of the claw body exposed on the window surface side. Therefore, according to this invention, the window to which the area lattice is attached can also be used as an emergency exit in an emergency.
