Description

[Detailed description of the invention] This invention relates to the structure of three sliding windows that are mainly used as side windows of greenhouses.

Generally, the side windows of a greenhouse are opened and closed primarily to control the indoor temperature, but in the past, each window was opened and closed separately. In this case, there would be variations in temperature between the open and closed parts, making it impossible to adjust the temperature throughout the room to a uniform temperature.Additionally, an opening device would be required for each meeting, which would require a lot of time and effort to install. There were various drawbacks such as not only increased labor costs but also complicated operation.

Furthermore, in the past, two or four shoji screens were installed on one window frame to form one window, so when the window was opened, the open area was only half of the entire window frame. There was also the problem that good ventilation could not be achieved without

Therefore, in this proposal, instead of opening and closing each window separately, the windows formed in a row of windows are opened and closed all at once to adjust the indoor temperature to a uniform temperature without variation.
Regarding the meeting point, by using one fixed shoji and two movable shoji, an open area of two-thirds of the window frame can be obtained, and the fixed shoji is located in the center of the window frame. This is intended to enable smooth opening and closing operations.

The present invention will be explained below based on embodiments shown in the drawings.

A is a window with three shoji screens installed in the window frame 1, and this window A
A plurality of these are arranged horizontally in parallel along the side wall of the greenhouse to form a continuous window structure.

The three shoji in meeting point A are fixed shoji 2, which is positioned in the center of window frame 1, and fixed shoji 2, which is positioned on the left and right sides of window frame 1 in the closed state, and moved to the center of window frame 1 in the open state. Movable shoji 3
, 4. Therefore, in the open state of meeting A, the above three shoji 2.3. 4 is located in the center of the window frame A and is in a superposed state.

The window frame 1 has left and right side frames 1a, la, and upper and lower frames 1b.

1c in a rectangular frame, and the upper frame 1b
are the four rails 1b-1, 1 vertically installed on the mounting board 1b'
The interior is divided into three spaces s1.b-2, 1b-3, and 1b-4. s2. The substrate l is formed into a box shape divided into s3, and the lower frame 1c is sloped downward toward the outside.
Three rails 1c-L lc L lc on c'
3 is formed in an upright shape.

Reference numeral 5 denotes a U-shaped frame attached to the lower part of the central space S2 of the upper frame 1b with the opening facing downward. Rail 1b
-2, and then touch the other side of the upper surface of the frame 5 to the rail 1.
It is configured in a cantilever suspension type with screws 7 fixed to the lower surface of b-3.

Then, in the center of the window frame 1, the upper part of the fixed shoji 2 is fitted into the frame 5, and the door roller 2' provided at the lower part of the fixed shoji 2 is placed on the 1 cm2 rail of the lower frame 1c and fixed. A shoji 2 is fixedly supported on a window frame 1.

Further, the movable shoji 3, 4 are arranged in spaces S1. on the indoor side and on the outdoor side of the upper frame 1b. It is suspended and supported in S3, and the hanging structure in this case is that two hanging fittings 8, 8 are attached to the top of each movable shoji; Rollers 9, 9 are pivotally supported with the metal fittings 8 sandwiched between the upper sides of the metal fittings 8, 8, and these rollers are placed in the spaces sl, s.
It is configured to be hung by being hooked onto the edge of a rail that protrudes into the interior of 3.

In addition, what is indicated by 2'' is the fixing metal fittings for the fixed shoji 2, and 3',
4' is a door roller installed at the bottom of each movable shoji 3, 4;
It is provided so that a slight gap is created between the lower frame 1c and the rails 1c-1, 1c-3.

Further, 10 is an airtight seal piece. Also, 11 is roller chain 1
2 and connected in an endless manner,
The roller chain 12 is not linked to a sprocket 13 provided at one end of the continuous window, but is hung around a direction changing sheave 14 provided at the other end of the continuous window so as to be suspended over the entire continuous window.

Each movable shoji 3, 4 of the meeting A is connected to this pulling wire 11.
In this case, the right movable shoji 3 of the meeting A is fastened to the indoor side of the wire 11, and the left movable shoji 4 is fastened to the outdoor side of the wire 11.

For this fastening, a fastener 15 is provided on the hanging metal fitting 3 of each movable shoji 3, 4, and this fastener 15 is used to fasten it to the wire 11. The side frame 1a is suspended between each window.
, la.

Note that the reference numeral 11' indicates a turnbuckle for adjusting the tension of the pulling wire 11.

Reference numeral 16 denotes a reciprocating drive device connected to the traction wire 11, which includes a drive section 17 using a forward/reverse drive motor 17', a sprocket provided on the sprocket shaft 13' provided at one end of the continuous window, and a chain connected thereto. It is constituted by an operating section 19 consisting of a roller chain 12 that fits together.

The drive unit 17 is equipped with a manual operation mechanism via a clutch, and is also equipped with a torque limiter to prevent overload.
is provided.

Therefore, in order to open the window A from the closed state, the movable shoji 3
, 4 to the center of the window frame 1, and the three shoji 2, 3, and 4 are placed in a stacked state at that position. At this time, if the drive motor 17' is rotated in the forward direction, this The sprocket 13 of the actuating part 19 interlocked with the sprocket 13 rotates, and the roller chain 12 coupled to the sprocket 13 is rotated in the direction of the arrow m.
As the traction wire 11 rotates in the same direction,
The movable shoji 3 on the right side fixed to this is towed and moved to the left within the window frame 1, and the movable shoji 4 on the left side is towed and moved to the right while the meeting A of the continuous window structure is linked in unison. It will be opened up.

Next, in order to close the window A from the open state, the drive unit motor 17' may be reversed to rotate the traction wire 11 in the direction of the arrow n.In this case, each movable shoji 3, 4 of the window A will close the window A while moving in the left and right direction from the center of the window frame 1 in conjunction with the movement.

Since the fixed shoji 2 is located at the center of the window frame 1, both movable shoji 3 and 4 only need to be moved by one shoji.

Furthermore, since the moving range of the movable shoji 3 and 4 is the range of one shoji, the length of the roller chain 12 only needs to be the length of one shoji, and the length of this roller chain 12 can be shortened. .

Furthermore, if the roller chain 12 is suspended so as to rotate horizontally as shown in the drawings, the roller chain 12 can be prevented from sagging, and accidents such as the chain 7 falling off can be prevented.

As mentioned above, according to the present invention, since the windows having a continuous window structure can be opened and closed in conjunction with each other, the labor required for opening and closing them can be greatly reduced, making it easy and simple to control the temperature inside the greenhouse. In addition, unlike the conventional method, there is no possibility that the temperature varies locally, and the temperature of the entire greenhouse can be quickly adjusted to a uniform temperature.

In addition, since each movable shoji of the continuous window is fastened to a pulling wire in a series, there is no need to install an opening/closing device for each window, and the movable shoji has a hanging structure, which reduces the driving force required to move the shoji. is small, and therefore a small drive motor can be used even in the case of a continuous window structure.

In addition, since a large open area of 2/3 of the window frame can be obtained, not only can ventilation be extremely good, but also
Since the fixed shoji is located in the center of the window frame, the movement range of the movable shoji is the minimum range of one shoji, which is common to both sides, and this reduces accidents caused by the movement of the shoji. This has the effect of allowing smooth driving.
