Description

[Detailed explanation of the invention] "Industrial application field"
This relates to a fixing device that allows louvers, etc. to be easily removed with a single touch in the event of an emergency such as a fire.

``Prior art'' Conventionally, these grids, blindfolds, etc. have been fixedly attached to the wall due to their purpose, and fixing devices such as screws are usually inserted from the outside into through holes made in the frame on both sides. It was common for grids, blindfolds, etc. to be fixedly attached by inserting a fastener into the wall and fixing the fastener to the wall. In addition, some lattices installed on doors had a structure in which the door frame and the lattice were hinged so that they could be opened and closed, and locked with a key.

Other similar technical documents include Jitsukai Sho.
There is a grid attachment device numbered No. 54-114453. This invention has a configuration in which the grid mounting portions are detachable via grid mounting fittings provided at each corner of the grid.

There is also an opening/closing window lattice No. 56-97393. This invention discloses a structure in which a lattice is pivotally connected to a window frame and can be opened and closed, and the lattice can be detached via a fitting means between a supporting rod and an engaging plate.

``Problem that the invention aims to solve'' Because grids, blindfolds, etc. are fixedly attached to walls, in the event of an emergency such as a fire or earthquake, even if windows and doors are opened, it will not be possible to get outside. This is a problematic area as it can lead to unexpected disasters if you are unable to escape. In addition, although grids and the like installed on doors can be opened and closed, they have a complicated structure and are expensive, so they are not widely used, and they are not suitable for use in window grids.

Indeed, in the above-mentioned technical document, the grid is designed to be removable.

However, the invention of Utility Model Application No. 54-114453 is
Since the lattice mounting brackets are each separate pieces (they are placed in each corner, i.e., there are four individual pieces), it is time-consuming in case of an emergency, and the upper lattice mounting brackets must be installed first. If removed, the lower grid mounting bracket will remain and there is a high risk that the grid will become distorted and become impossible to remove. Furthermore, the grid is completely free from the wall (wall panel) and will fall when removed, making it extremely dangerous.

Furthermore, the invention of Utility Model Application Publication No. 56-97393 has a structure in which the lattice is pivotally attached to the window frame, and it is necessary to press it down each time during evacuation, which is troublesome and difficult for young children.
It is not considered to be very effective in an emergency because it requires force to open the door for children and others, and it is especially difficult for them to move the cap in an emergency.

"Means for Solving the Problems" In order to solve the above problems, the present invention uses windows,
A plurality of support rods are provided at appropriate intervals on the left and right frame materials for door lattices, blindfolds, etc., and the support rods are inserted into through holes made in the wall, and the recesses provided in the support rods are inserted into the through holes. The lattice is made more protruding,
Attach blindfolds, etc. to windows, etc. Next, an engaging plate having a long hole that fits into this protruding recess is provided, and the grid or the like is fixed in this fitted state. The structure is such that a removal means is provided for releasing the fitted state, that is, removing the grid or the like.

"Function" Next, the working state of the present invention will be explained. A plurality of support rods 3, 4 having recesses 5 at their tips protrude from the left and right frame members 2, 2a of the grid, blindfold, louver, etc. 1.
are inserted into the through holes 6 and 7 provided in the wall A near the window, and the recess 5 thereof protrudes from the wall A. Then, the long holes 12 of the engagement plate 11 are inserted into the recesses 5 of the respective support rods 3 and 4.
By fitting the ends, the support rods 3, 4 and the engagement plate 11 are integrated, and the grid is attached to the wall A. In the event of an emergency such as a fire,
By operating the operating rod 15, in the embodiment shown in FIGS. 1 to 3, the locking piece 16 that rotates at the same time as the operating rod 15 pushes up the engagement plate 11, so that one side or the other side is supported. When the recesses 5 of the rods 3 and 4 and the engagement plates 11 provided on the left and right ends are removed, the recesses 5 of the two support rods 3 and 4 in the vertical direction on one side, for example, and the engagement plates 11 are removed. mating at the same time,
When the engagement plate 11 is released with one touch and then the engagement plate 11 is removed, the engagement plate 11 and the recesses 5 of the two vertical support rods 3 and 4 on the other side are simultaneously engaged.
The problem can be solved with a single touch, and the state shown in FIG. 2 will be achieved. For example, the grid will be in a free state and can be easily removed. Further, in the embodiment shown in FIGS. 4 and 5, the operating rod 15 is rotated, and the engagement plate 11 falls into the recess 15a, and as a result, the engagement plate 11 falls. As a result, the engagement between the recesses 5 of the support rods 3 and 4 and the engagement plate 11 is released, and the grid etc. are placed in a free state, so that they can be easily removed. Therefore, in various emergencies, the grid etc. can be removed very easily with a one-touch operation.

"Example" An embodiment of the present invention will be described based on the drawings.

1 is a lattice, blindfold, louver, etc. for windows, doors, etc., and 2 and 2a are frame materials at the left and right ends thereof. At least two support rods 3 and 4 (hereinafter simply referred to as support rods 3 and 4) in the vertical direction are protruded from the left and right end side frame members 2 and 2a at appropriate intervals, respectively.
The support rods 3 and 4 are provided with recesses 5 that open upward. The support rods 3, 4 are inserted into through holes 6, 7 formed in the wall A near the window, and the recesses 5 thereof are located indoors. 8 and 9 are sheath tubes fitted into the through holes 6 and 7,
Reference numeral 10 is a chain for preventing a grid or the like from falling. 11 is a vertical support rod 3 on one side that protrudes toward the indoor side;
