Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sunroom, more specifically, to a device for winding up and unrolling a sunshade provided on the roof.

Prior Art A sunroom has a roof section made of a light-transmitting plate, and sunlight is brought into the room to be used as a living room, etc. for temperature control.

In such a sunroom, the indoor temperature may become too high when sunlight energy is strong, such as in summer.

Therefore, the applicant first provided a sunshade on the roof, and by winding up and unrolling this sunshade with a winding drum, the roof could be covered with the sunshade or opened. I applied for a sunroom that looked like this.

Wind up the awning in the sunroom as mentioned above,
In order to unroll it, it is conceivable to connect an operating string to the leading edge of the awning, and to operate the operating string to wind up and unroll the awning.

However, with this configuration, when the sunshade is extended to cover the roof, the operating strings are stretched across the inside of the roof, and the operating strings are visible from inside the sunroom, resulting in a poor interior appearance. Put it away.

Therefore, the present applicant previously filed an application for a sunroom in which the rafters constituting the roof are hollow, and the operating strings are strung through the hollow portions so that the operating strings are not visible from inside the sunroom.

However, with this configuration, if the operating string is cut and replaced with a new one, or if the operating string gets caught in the hollow part of the rafter, it is necessary to take the operating string out of the hollow part of the rafter and hang it. The work becomes extremely troublesome, and in the worst case scenario, the rafters must be removed.

Purpose of the invention The purpose is to provide a sunroom with an excellent interior appearance without making the operating string visible from inside the sunroom, and to enable easy replacement, inspection, and maintenance of the operating string.

Structure of the device An upward concave groove is formed in the longitudinal direction on the vertical beam installed between adjacent rafters, and a guide rod connected to the awning is installed so as to be able to freely slide between the adjacent rafters. , an operating string connected to the guide rod is stretched across the vertical beam along the bottom of the groove.

It has a shape in which a guide rail 14 is provided on the upper part of the main body 13 having the same height, and the guide rail 14 has upper and lower rail parts 14a, 14a, and the upper and lower rail parts 1
Rollers 15 provided on both sides of the guide rod 12 are rotatably provided between 4a and 14a, and the guide rod 12 is connected to the adjacent rafters 5, 15 via the left and right rollers 15, 15.
It is movable along guide rails 14, 14 of No. 5.

The purlin 4 includes an upper wall 4a and a vertical wall 4b, and one end of the main body 13 of the rafter 5 and the vertical beam 6 are butt-connected to the vertical wall 4b, and the guide rail 1 of the rafter 5 is connected to the vertical wall 4b.
4 is located above the upper wall 4a.

As shown in FIG. 3, the vertical bar 6 has a lower vertical bar 20.
and an upper vertical bar 21, and the upper vertical bar 21 is connected to the upper and lower walls 21.
a, 21b and both side walls 21c, 21c form a long material having a hollow part 21', and the lower wall 21b
A bottom plate 22 is integrally formed in each of the bottom plates 22 and 22.
An upstanding piece 23 is integrally formed at the tip of the bottom plate 22, and an upward groove 24 is continuously formed in the longitudinal direction. A transparent plate 9 is attached between the two through a packing 25 and a sealing material 26, and a sliding plate 27 made of synthetic resin is attached to the bottom of one of the grooves 24 (that is, the bottom plate 22) in the longitudinal direction. It has been laid down over a long period of time.

A guide roll 28 is rotatably attached to the eaves beam 1 of one side wall 21c of the upper vertical beam 21 on the side of the sliding plate 27, and a bracket is installed at a position facing the sliding plate 27 on the upper wall 4a of the purlin 4. 2
A pulley 30 is rotatably provided via the pulley 30 and the guide roll 28, and an endless ball chain 31 serving as an operating string is stretched across the pulley 30 and the guide roll 28 so as to be in contact with the slide plate 24. The other end of the ball chain 31 hangs down inside the sunroom and is connected to the guide rod 12 via a connector 32.

Note that a hole 33 for ball chain insertion is formed in the vertical wall 4b of the purlin 4, and the ball chain 31 slides along a guide 34 fitted in this hole 33.

The winding device 11 includes a winding drum 40 and a cover 41, and the winding drum 40 has a cylindrical shape,
Pivot supports 42 and 43 are fixed to the openings at both ends, and a stopper 44 is attached to the pin 45 at the longitudinally intermediate portion.
At the same time, one shaft support 42 is attached to a bracket 46 fixed to the upper wall 4a of the ridgepole 4.
7, and a fixed shaft 48 fixed to the upper wall 4a of the purlin through a bracket 51 is rotatably inserted and supported in the other shaft support 43, and the fixed shaft 48 and the stopper 44, a coil spring 50 is attached to the shaft 49 in the longitudinal direction, one end 50a of the coil spring 50 is fixed to the shaft 49, the other end 50b is fixed to the stopper 44, The coil spring 50 biases the winding drum 40 to rotate in the sunshade winding direction.

Note that the rotational biasing force of the coil spring 50 is
The sliding resistance is weaker than that of the guide rod 12 and the sunshade 10, so that the sunshade 10 will not be automatically rolled up even if the ball chain 31 is released.

In other words, when the sunshade 10 is moved in the winding direction by the ball chain 31, the rotation biasing force is sufficient to wind the sunshade 10 so that it does not bend.

Therefore, when the ball chain 31 is pulled in one direction, the ball chain 31 rotates in one direction while rotating the guide roll 28 in one direction, so that the portion 3 connected to the guide rod 12 via the connector 32
1' moves in one direction (for example, toward the eave sill 1 side) and moves the guide rod 12 along the guide rail 14 toward the eave sill 1 side, so that the sunshade 10 is extended and covers the roof.

At this time, the winding drum 40 is rotated in the unwinding direction, bending the coil spring 50, and storing rotational biasing force in the winding direction.

Furthermore, when the ball chain 31 is pulled in the other direction and rotated in the opposite direction, the portion 31' moves in the other direction (for example, toward the purlin 4 side),
Since the guide rod 12 is moved toward the ridgepole 4 side along the guide rail 14, the shade 10 is wound around the winding drum 40 and the roof portion is opened.

At this time, the winding drum 40 is moved by the coil spring 5.
Since the sunshade 10 is rotationally biased in the winding direction at zero, the sunshade 10 can be wound up in a constant state of tension without sagging.

In addition, the ball chain 31 is connected to the vertical bar 6 (upper vertical bar 2).
1) Since it spans the concave groove 24, it is not visible from inside the sunroom, giving an excellent interior appearance, and the ball chain 31 can be easily removed from the concave groove 24 and can be viewed from above. ,
Replacement work when the ball chain 31 breaks,
When the ball chain 31 gets stuck or once stops moving, it can be easily and easily handled, so that the ball chain 31 can be easily replaced, inspected, and maintained.

Further, since the ball chain 31 slides along the sliding plate 27 provided at the bottom of the groove 24, the sliding resistance of the ball chain 31 is reduced, and the ball chain 31 can be rotated smoothly with a small force. No abnormal noise is generated when the ball chain 31 slides.

Note that although a ball chain was used in the above embodiments, wires, ropes, etc. may also be used.

5 and 6 show the second embodiment, FIG. 5 is a schematic perspective view of the entire sunroom, and FIG. 6 is an exploded perspective view of the part of the ball chain hanging into the sunroom, and the roof A pair of left and right inner columns 60, 60 and outer columns 61, 61 are erected below the four corners of the section to support the roof and constitute the main body. Box-shaped first and second brackets 64 and 65 holding first and second auxiliary pulleys 62 and 63 are attached to the lower part of the ridgepole 4, and the ball chain 31 is guided from the guide pulley 30 to the first window hole of the first bracket 64. 66 and wrap it around the first auxiliary pulley 62, and then pull it out through the second window hole 67 of the first bracket 64 and insert it into the first window hole 68 of the second bracket 65.
is inserted and wrapped around the second auxiliary pulley 63 and hung inside the sunroom from the second window hole 69 along the inner pillar 60, and is attached between the first and second brackets 64 and 65 on the purlin 4. An upward U-shaped cover 71 is fixed to the mounting plate 70 with screws 72.
Ball chain 31 between second auxiliary pulleys 62 and 63
is covered.

With this configuration, the lower end of the ball chain 31 can hang down along the inner pillar 60 of the sunroom, which is preferable because the ball chain 31 does not get in the way.

In addition, in each of the above embodiments, the rafters 5 and the vertical beams 6 are installed at intervals of 3 shaku, so the rafters 5, 5
Since the distance is 6 shaku, the width of the sunshade 10 should be 6 shaku.

In addition, as shown in Figure 7, there are two
When the ceiling frame portion 8 is formed by constructing vertical book beams 6, 6, the distance between the rafters 5, 5 will be 9 shaku, so the shade 10 may also have a width of 9 shaku.

In this way, if you prepare an awning with a width of 6 shaku and an awning with a width of 9 shaku, not only the ceiling frame part at 6 shaku intervals, but also the awning with a width of 9 shaku.
The roof of the sunroom has ceiling frames spaced 9 feet apart as shown in Figure 7, ceiling frames spaced 12 feet apart as shown in Figure 1, and ceiling frames spaced 15 feet apart as shown in Figure 8. A sunshade can be attached to the area.

Note that the ball chain is stretched along the vertical bars 6 in the same manner as described above, and in the case of a ceiling frame section spaced at 9-shaku intervals, the ball chain may be stretched along either one of the vertical bars 6.

[Effect of the invention] Since the operating string is stretched around the guide roller 28 and the pulley 30 along the bottom of the groove 24 formed in the vertical beam 6, the operating string is not visible from inside the sunroom and the interior appearance is excellent. In addition to creating a sunroom with a sunroom, there is no need to perform any special processing on the rafters 5 or the vertical beams 6.

Since the concave groove 24 formed in the vertical bar 6 is located above the transparent plate 9, the operating string can be easily removed from the concave groove 24 and can be visually inspected from the top of the concave groove 24, making it easy to remove the operating cord. In addition to being able to replace the
Maintenance becomes easier.

Since the awning 10 is connected to the guide rod 12 slidably installed between the guide rails 14 of the rafter 5, the awning 10 can be smoothly rolled up by sliding the guide rod 12 along the guide rail 14. It can be rolled out.
