Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a surface lattice to be attached to the outside of a window, more specifically, an openable surface that can be opened and evacuated from a fire, earthquake or other emergency. Regarding the lattice.

[Conventional technology]

In a normal surface lattice, a plurality of vertical rails are attached across an upper rail and a lower rail to form a lattice unit, and the lattice unit is attached to the outside of the window.

Such a plane lattice is firmly fixed to the wall surface of the building for the purpose of crime prevention or danger prevention, and cannot be easily removed.

Therefore, in the event of an emergency such as a fire or an earthquake, it is impossible for people in the room to evacuate from the window to which the screen lattice is attached.

Therefore, as disclosed in Japanese Utility Model Laid-Open No. 58-134589, a plane lattice has been proposed in which a part of the lattice unit can be easily opened from the indoor side.

That is, a part of the lattice unit can be rotated inward,
A surface lattice in which the shoji of the window is opened, a part of the lattice unit is rotated to the inside of the room through the opening to release a part of the surface lattice, and a person can evacuate from the released portion.

[Problems to be solved by the device]

With such a surface lattice, a part of the lattice unit rotates inward with the upper part as a fulcrum and enters the opening of the window.
It is necessary to prevent the lower part of the lattice unit and the lower part of the window from interfering with each other.

For this reason, the lower part of the vertical rails that form the lattice unit cannot be projected below the lower part of the window, and the appearance as a surface lattice becomes unattractive, and the installation interval between the lattice unit and the window becomes large, and the surface lattice is If there is an obstacle adjacent to the window that protrudes more than the outer surface, the work of attaching the area lattice becomes troublesome.

Therefore, an object of the present invention is to provide a surface grating which can solve the above-mentioned problems.

[Means and Actions for Solving the Problems]

In the open part of the lattice unit, a plurality of vertical rails are attached to the swing horizontal rail so that it can slide up and down, and a lower rail cover is horizontally connected to the bottom of each vertical rail, and the swing horizontal rail is rotated to the upper rail. The surface lattice that is attached so that the lower rail cover is releasably engaged with the lower rail and that the open portion is slid upward and then pivoted inward to release part of the surface lattice. Is.

In addition, the main body 17 includes a main body 17, a cover 18, and a slide bush 19, and the main body 17 connects the upper plate 20 and the lower plate 21 with a vertical plate 22 and projects one end portion 20a of the upper plate 20 from the vertical plate 22 so as to face downward. A substantially circular downward recess 23 that is curved in an arc shape and is rotatably fitted to the upper rail 11 is formed, and the upper plate 20, the lower plate 21, and the notch 24 are spaced from each other in the longitudinal direction. The cover 18 is formed in a vertical plate shape and has an engaging piece 25 at the upper edge.
A bent piece 26 is provided at the lower edge, the engaging piece 25 is engaged with the engaging piece 20b of the upper plate 20, and the bent piece 26 is fixed to the lower plate 21 by a fastener 27.
The cover 18 is attached to the main body 17 by connecting with each other, and a resin-made slide bush 19 in the shape of a rectangular tube is provided between the cover 18 and the notch 24.

As shown in FIG. 3, the lower rail cover 15 is a long member having a downward U-shaped cross section, and is removably engaged with the upper portion of the lower rail 13.

The vertical bar 16 is a long member having a rectangular cross section, an upper part of which is slidably fitted to a slide bush 19 and a lower bar cover 15 is connected to a lower chamber outer wall 16a by a fastener 29. A slide regulating groove 30 is formed on the upper portion of the indoor wall 16b, and the slide bush 19 is formed in the slide regulating groove 30.
The slide regulating stopper 31 provided on the
The vertical stroke of the vertical bar 16 is regulated, and the vertical stroke l ₁ thereof is larger than the engagement depth l ₂ between the lower bar 13 and the lower bar cover 15, and the opening of the lattice unit D is defined as a chamber. When it is turned inward, the open part is the window frame 4
The dimensions are set so as not to interfere with the lower portion of the vertical rail 16, and when the length between the lower portion of the vertical rail 16 and the engaging portion of the lower rail cover 15 is l ₃ , then l ₁ <l ₂ + l ₃ .

When the swing cross rail 14 and the lower rail cover 15 are divided into a plurality of parts in the longitudinal direction as shown in FIG. 5, the lattice unit D of the plane lattice C is opened when the shoji 5 of the window 6 is opened as shown in FIG. Open portions D ₁ and D ₁ facing the openings 6a and 6a, and a central fixed portion D facing the meeting portion 5a of the shoji 5.

As shown in FIG. 6, any one of the plurality of vertical bars 16 provided in the open portions D ₁ and D ₁ is fixed by the fixing means 32 so as not to slide on the swing horizontal bar 14, and the fixing means 32 is fixed. As shown in FIG. 7, the cover 33 penetrates the slide bush 19 and is fitted into the indoor wall 16a of the vertical crosspiece 16, and can be easily pulled out by pulling from the indoor side by hand.

In the event of a fire or earthquake, open the shoji screen 5,
Releasing the connection of the vertical bar 16 and the swing rungs 14 extracts the pin 33 from the opening 6a of the window 6, the lower rail cover 15 is slid upward with the vertical bar 16 of the open portion D ₁ of the grating unit D Is separated from the lower crosspiece 13.

In this state, the open portion D ₁ of the lattice unit D is housed in the opening 6a of the window 6 by pivoting the upper crosspiece 11 toward the room as shown by the phantom line in FIG. It is held in a substantially horizontal posture by a holding mechanism (not shown) provided.

As a result, a part of the area lattice C is opened, so that a person inside the room can evacuate to the outside.

In this way, since the open portion D ₁ of the lattice unit D is slid upward and then pivoted inward, the vertical bar 16 is pivoted inward while it is in the upward position. In the attached state, even if the lower portion of the vertical rail 16 projects downward from the lower portion of the window 6, for example, the lower frame 2, the lower portion of the vertical rail 16 does not interfere with the lower frame 2 when it is rotated in the room.

Further, since the vertical rail 16 slides along the slide bush 19, it can be smoothly slid upward with a light force, and further, the sliding stroke can be regulated by the slide regulation stopper 31 and the slide regulation groove 32, so that the lattice unit D is opened. The part D ₁ can be easily rotated to the indoor side.

In the above embodiment, the upper crosspiece 11 and the lower crosspiece 13 are connected to the building wall A through the upper bracket 10 and the lower bracket 12.

Further, in the above embodiment, the lower rail cover 15 has a downward U-shape and is vertically engaged with the upper portion of the lower rail 13. However, the lower rail cover 15 is provided with a downward pin, and the lower rail 13 has an upper pin. A hole may be formed to engage the pin with the pin hole.

That is, the engaging portion may be formed on the lower rail cover 15, and the engaged portion may be formed on the upper portion of the lower rail 13.

Further, although the fixed portions D ₂ and D ₃ of the lattice unit D have the same configuration as the open portion D ₁ in the above embodiments, the fixed portions D ₂ and D ₃ may have other arbitrary configurations.

[Effect of device]

1. The fixing means 32 is released from the indoor side so that the vertical rail 16 can slide up and down with respect to the swing horizontal rail 14, and in this state, the open portion D ₁ of the lattice unit D is moved upward to move the lower rail cover 15 By disengaging the engaging portion from the engaged portion of the lower crosspiece 13, the open portion D ₁ can be turned to the indoor side to release a part of the surface lattice, so that the person inside the room can evacuate to the outside.

Further, since the vertical rail 16 is slid upward and then pivoted inward, even if the lower portion of the vertical rail 16 is projected below the lower portion of the window 6 with the open portion D ₁ of the lattice unit D attached. The lower part of the vertical bar 16 and the lower part of the window 6 can be rotated to the indoor side without interfering with each other, and the vertical bar 16 can be projected to the lower part of the window 6 to improve the appearance, and the lattice unit D and the window. Since the space between the surface lattice and the space 6 can be made small, the surface lattice does not protrude much more toward the outside of the room than the window, and the surface lattice can be easily attached even if there is an obstacle adjacent to the window.

Further, when the open portion D ₁ of the lattice unit D is attached, the engaging portion of the lower rail cover 15 engages with the engaged portion of the lower rail 13, and the lower rail cover 15 cannot move to the indoor side. Since the swing horizontal rail 16 and the vertical rail 16 are connected by the fixing means 32 and the vertical rail 16 cannot move upward, the portion D opened from the outside of the room
It is very difficult to rotate ₁ toward the indoor side, and since the shoji has to be opened, it is virtually impossible for another person to rotate the open portion D ₂ from the indoor side to the indoor side and enter the room. Is.

2. Since it restricts the vertical stroke of the vertical bar 16, always without sliding upward more than necessary open portion D ₁ of the grating unit D can slide upward by a predetermined stroke, the open portion of the grating unit D ₁ Can be rotated to the room side with a simple operation.
