[0001]

BACKGROUND OF THE INVENTION The present invention relates to a surface grid to be mounted on the outdoor side of a window. In particular, when necessary, each grid bar is brought to one side of the window to have a function of opening the window widely. It relates to an expression plane lattice.

[0002]

2. Description of the Related Art As a surface grating of this kind, Japanese Utility Model Publication No. 60-3
No. 915 is known. As a mechanism for bringing each lattice bar to one side of the window, each lattice bar is connected at both upper and lower ends by a telescopic mechanism connecting a series of X-shaped links, and the distance between the lattice bars is made freely expandable and contractable. The grid bars are locked to the vertical frame, and each grid bar is fixed and installed at equal intervals.However, by releasing the lock, each grid bar is pushed out by a spring in the opening direction, and then manually. It is configured to be fully open.

[0003]

The spring according to the above-mentioned publication is attached to both upper and lower ends of a vertical frame provided with an expansion / contraction mechanism of a lattice bar, respectively.
That is, since the upper and lower parts of the grid bar are urged by individual springs, the grid bars are pushed out in a tilted state due to the difference in the urging force of each spring, but the same urging force is applied. The spring has a lattice bar that is tilted due to the difference in sliding resistance between the upper and lower parts of the lattice bar. There is a problem that the parallel movement is difficult unless pressed.

An object of the present invention is to solve the above-mentioned problems, and to provide a movable surface grid having a function that allows the grid bar to be surely moved in parallel even when the grid bar is started and when it is manually operated. It is in.

[0005]

According to the present invention, there is provided a solution in which a plurality of grid bars are connected to each other by a telescopic mechanism at the top and bottom of a frame, and the two floating parts of the upper and lower telescopic mechanisms are opposed to each other. Are connected to each other by a spring.

[0006]

As described above, by connecting the upper and lower floating parts to each other with a spring, even if the sliding resistance of the upper and lower parts is different, a corresponding pulling force is applied, and as a result, the grid bar is securely translated. can do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a plurality of lattice bars 2 are arranged in a frame 1 as shown in FIG.
The frame 1 is structured so that it can be suspended vertically and slid in the horizontal direction. The frame 1 has left and right vertical frames 3, 3, an upper horizontal frame 4, and a lower horizontal frame 5, as shown in FIGS. The vertical frame 4 is a U-shaped cross section having an open mouth on the side, and the upper horizontal frame 4 is a U-shaped cross section having an open mouth below. As shown in the figure, screw holes 6,
6 and a rail 7 protrudes from the upper wall of the inner surface.
The lower horizontal frame 5 is a shaped material having substantially the same shape as the upper horizontal frame 4, except that the rail 7 is not provided.
The frame 1 is formed by inserting both ends of the lower horizontal frame 6 into left and right vertical frames 3 and 3 and screwing them (not shown), and covering the upper end of the vertical frame 3 with a cap 8.

On the other hand, as shown in FIG. 2, the grid bar 2 is a profile member having a hollow section and a concave groove 9, and slidable blocks 10 and 11 are fitted into upper and lower ends of the grid bar 2. ,
The upper sliding block 10 is engaged with the rail 7 of the upper horizontal frame 4 as shown in FIG. In addition, a door wheel 12
Are protruded so as to engage with the upper surface of one of the screw holes 6 and suspended, and the lower end of the lattice bar 2 is slidably engaged in the lower horizontal frame 5. The grid bars 2 suspended in this manner are connected at upper and lower portions thereof with expansion and contraction mechanisms 13, 14 having a plurality of X-shaped links connected continuously, and the connection structure is shown in FIGS. 2 and 3. As shown in the figure, on the upper side of the grid bar 2, both upper ends of the X-shaped link are pivotally supported on the upper slat block 10, and wheels 15 are attached to both lower ends. 2 is engaged with the concave groove 9. On the lower side of the lattice bar 2, it is mounted in the opposite direction to the upper side.

In each of the lattice bars 2 connected by the upper and lower telescopic mechanisms 13 and 14 attached as described above, as shown in FIG. 1, a lock portion 16 for the vertical frame 3 is attached to the lattice bar 2a at one end. The lattice bar 2b at the other end is fixed to the vertical frame 3 facing the lattice bar 2 by appropriate means. Therefore, as shown in FIGS. 3 and 4, the structure of the lock portion 16 is such that a substrate 19 having bending pieces 17 and 18 provided at the upper and lower ends of the vertical frame 3 is fixed to an intermediate portion between the upper and lower sides of the substrate 19. The support pins 20 are protruded toward the lattice bar 2 a, and the upper and lower refraction pieces 17
8, a sliding plate 21 is provided so as to be vertically movable by engaging the support pin 20 with a vertically long hole 22 provided at an intermediate portion thereof, and the sliding plate 21 is urged downward by a compression spring 23. I have. In addition, the wire 24 is inserted into the vertical frame 3 from the upper end on the indoor side of the room and the wire 24 is hung downward to slide the sliding plate 21.
The wire 24 is inserted into the upper refraction piece 17, and a lower end of the wire 24 is provided with an enlarged portion 25 for retaining. Therefore, the compression spring 23 is pulled by pulling the wire 24 from the indoor side.
The sliding plate 21 can be pulled up against the pressure. Further, a swinging plate 26 is supported by the support pins 20 in parallel with the sliding plate 21, and an upper locking groove 27 is provided at an upper portion of the rocking plate 26, and a lower locking groove 28 is provided at a lower portion thereof. A receiving groove 29 is formed at the shoulder of the upper locking groove 27, and an upper locking pin 30 protruding from the sliding plate 21 is engaged with the upper locking groove 27. Lattice bar 2 in groove 28
The lower locking pin 31 protruding from a is engaged.

Therefore, as described above, when the sliding plate 21 is lifted by pulling the wire 24, the upper locking pin 30 protruding from the sliding plate 21 comes out of the upper locking groove 27 of the swing plate 26. However, the lower locking pin 31 provided on the lattice bar 2a is still engaged with the lower locking groove 28 of the swing plate 26, and the lock cannot be released as it is. In order to release, the grid bar 2a is forcibly moved out of the vertical frame 3 so that the lower locking pin 31 provided on the grid bar 2a presses the rocking plate 26 sideways as shown in FIG. The lock is released. Moreover, when the swinging plate 26 is pressed laterally, the pulling by the wire 24 is released before that, and the sliding plate 21 is urged downward by the restoring force of the compression spring 23. Rocking plate 26 in which upper locking pin 30 is inclined
And the sliding plate 21 is held in an inclined state. On the other hand, when the grid bar 2a is moved back from the released state of FIG. 5, the inclined locking plate 31 provided on the grid bar 2a is pressed in the direction in which the inclined swinging plate 26 is moved back. 30 is disengaged from the receiving groove 29 and the sliding plate 21 is urged downward by the compression spring 23, so that the upper locking pin 30 engages with the upper locking groove 27 of the upright rocking plate 26, Further, the lower locking pin 31 is deeply engaged with the lower locking groove 27 and is locked again.

The present invention is characterized by a structure for forcibly moving the lattice bar 2a out of the vertical frame 3 as shown in FIG.
As shown in the figure, the grid bar 2b fixed to the vertical frame 3 at the end opposite to the grid bar 2a having the lock portion 16
, The floating portions 13a, 14 of the upper and lower telescopic mechanisms 13, 14 which are engaged with the lattice bars 2b via wheels 15.
a are connected to each other by a tension spring 32. However, the tension spring 32 is not limited to the lattice bar 2b at the end, but may be the lattice bar 2 having the lock portion 16.
The tension spring 32 may be attached to the grid bar 2 other than the grid bar 2 having the above-described structure.
Not only that, but it may be attached to several grid bars 2.

With the above structure, when the surface grid is to be released from a closed state (a state in which a grid bar having a lock portion is placed in a vertical frame) as shown in FIG. Is released and the tension spring 3
2, the upper and lower telescopic mechanisms 13 and 14
Are simultaneously contracted, so the locked grid bar 2a
Is pulled out from the vertical frame 3 and at the same time, the interval between the lattice bars 2 is contracted. If the tension spring 32 has a strong attractive force, the lattice bars 2 are in contact with each other. Even if the lattice bar 2a is stopped in a state where the lattice bar 2a is pulled out from the inside of the vertical frame 3, the tension spring 32 can be pressed by hand. However, at this time, since the tension spring 32 is attached as described above, the pressing force by hand is not limited to the central portion of the grid bar 2 but may be the lower portion or the upper portion. Does not tilt and moves while being suspended vertically.

[Effects of the Invention] In the case of the movable surface grid according to the present invention, a plurality of grid bars suspended from the upper horizontal frame are connected at upper and lower portions by a telescopic mechanism. The floating parts of the mechanism are connected to each other by tension springs, and biasing force is applied to each grid bar in the direction of approaching each other. Even if the resistance of each sliding part is slightly different from each other, the upper and lower sides are attracted by the tension springs, so that the upper and lower tensions are delicately adjusted to provide the effect of attracting, and as a result, each grid bar Is to slide while always maintaining a vertical state without being inclined by the tension force of the tension spring. In addition, when the grid bar is manually pressed, the tension force of the tension spring is applied, so that it can be pressed with a light force. Can be slid while maintaining a vertical state. In addition, since the sliding can be performed without tilting, the opening and closing can be performed smoothly and quickly without excessive resistance.
