[Structure] Sliders provided on the upper and lower back sides of each movable bar 2 that moves between both fixed bars 3 are slidably and irremovably fitted into the lips of rails 4, and each movable bar is linked by link connection. In addition, the opening bar can be quickly obtained by a one-touch opening device in which a rope and a tension spring are provided via a pulley on a floating bar that is attached to the end of the moving bar.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a surface lattice with a touch release device that complies with the conditions of conformity with the regulations concerning the lattice having an emergency opening function.

[0002]

[Prior art]

 Conventionally, the installation of a plane lattice outside the window for the purpose of crime prevention, fall prevention, or exterior was widely used, but it was a disaster because there was no emergency release function in case of emergency evacuation. Therefore, the plane lattice disclosed in the manual movement of the vertical crosspiece by unlocking the closing lock of the plane lattice (Japanese Utility Model Laid-Open No. 2-143492) was provided. It had the trouble and insufficiency that it could not be opened without doing so.

[0003]

[Problems to be solved by the device]

 This invention eliminates the deficiencies of the conventional technology and mass-produces a market-friendly surface grid with an open-ended device, which is equipped with various functions such as crime prevention, emergency opening, and maintenance safety, at low cost. , Contributing to the prevention of human disasters is an urgent issue.

[0004]

[Means for Solving the Problems]

 The solution means will be described with reference to the drawings. (A) A support base 9 and sliders 6 and 7 are integrally fixed to the upper and lower rear surfaces 2A of the movable bars 2 ... 2 which reciprocate between the fixed bars 3 and 3, respectively. . (B) The tip ends of the links 10 and 11 pivotally attached to the support bases 9 ... 9 are pivotally attached to the support pins 9 by a connecting pin 19. (C) The sliders 6 ... 6 and 7 of the movable rails 2 ... 2 are slidably and irremovably fitted into the upper and lower rails 4 and 4, respectively. (D) A rope is attached to the floating bar 20 with the lock groove 21 provided along with the slider 7 on the endmost movable rail 2B side, and is attached to another tension spring 15 in a U-turn shape via the pulley 17.

[Work]

 The present invention has the above-mentioned structure. When using this, first the sliding window is manually opened from the room, and then the floating bar 20 connected to the endmost moving bar 2B is locked. When the locking device (not shown) that allows the hooking member to be inserted into and removed from the outside of the rail 4 is released in the groove 21, the shortest moving bar 2B that is integral with the floating bar 20 due to the restoring force of the pulling spring 15 Since it is pulled in the direction of the arrow in FIG. 5, the links 10 and 11 in each of the moving bars 2 ... 2 tilt in an inverted V shape as the distance between the moving bars gradually decreases. When the sliders 6 ... 6 and 7 of each movable rail and the stop plate 8 on the stationary machine 3 side are all in contact, the movable rails 2 ... 2 and 2B stop slamming and the case 1 outside the window is opened. Since the part S can be formed, it is possible to perform an emergency escape in accordance with the purpose of the present invention (see FIG. 2). Further, in order to return the lattice 1 to the original state (see FIG. 1), when the slider 7 comes into contact with the stop plate 8 on the side of the fixed rail 3 by manually pulling the moving rail 2B at the extreme end sideways, Since the locking member (not shown) or the locking bar 21 of the floating bar 20 that has moved the same as the moving bar 2B is fitted and locked, the moving bar 2B at the end stops. Therefore, the links 10 and 11 in each of the moving bars 2 ... 2 are enlarged in order of the inverted V-shaped angle to maintain the distance between the moving bars evenly. Also forms a beautiful lattice 1 (see FIG. 1).

【Example】

 In implementing the present invention, the following can be done. (A) A U-shaped groove-shaped protection member 22 is fitted into the lip groove 4A of the rail 4 to prevent rainwater and dust from entering and protect the rope 16. (B) The lower end recess where the sliders of the movable rail and the lip 4B on the rail 4 side are in sliding contact is deepened, and a small pulley 23 is provided in the recess to smooth the movement of each movable rail (see FIG. 7). . (C) In the present invention, since the opening is moved from one side of the lattice 1, the surface facing the window of the endmost moving bar 2B is colored or fluorescent-painted in advance so that the lock is not unlocked. Use as a guide for the opening guide.

[0007]

[Effect of device]

 According to the present invention, when the blocking (locking device) of the floating bar is released, the opening is automatically secured, and even if the rope or the tension spring becomes inoperable, the opening can be obtained manually. In any case, emergency release can be performed. In addition, the sliding members on the moving rail side, as well as the rope, are all contained within the rails, so rainwater and dust are extremely well-prevented and highly durable. Furthermore, since it is not easy to break the grid and each actuating member from the outside, it is useful for crime prevention, and various functions that comply with regulations can be fully exerted.
