Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides sliding doors (single sliding doors, side sliding doors,
This relates to shutters that can be installed in the form of sliding doors, hinged doors, folding doors, or snap-on doors.

[Conventional technology]

Unlike blinds, shutters are an elegant fitting that matches indoor interiors and wooden furniture, and are often used for windows and entrances in homes.

These shutters are generally constructed by having a plurality of upper and lower blades horizontally attached within a frame-like frame consisting of upper, lower, left and right frames.

In this case, in conventional shutters, each blade is fixed between the left and right frames in an inclined state that partially overlaps when viewed from the front, and the direction and angle of each blade's inclination, as well as the opening degree (amount of opening between the blades) remained constant.

[Problem to be solved by the invention]

Therefore, since the amount of ventilation and lighting conditions are always constant, it is not possible to adjust the amount of ventilation and lighting conditions depending on the season, temperature and humidity conditions, or change the outdoor scenery through the shutters. There were various inconveniences when using it.

In addition, since the opening cannot be adjusted, window shutters require curtains on the indoor side, which is an economic waste, and also reduces the appearance of the shutters.

Therefore, the present invention provides a shutter that can adjust the direction and angle of the blade inclination and the degree of opening, and can change the amount of ventilation, lighting conditions, etc.

[Means to solve the problem]

The present invention comprises a plurality of upper and lower blades that are pivotally mounted between left and right frames so as to be rotatable about a horizontal axis, and stopper means that holds each of the blades in a plurality of rotational positions. (Claim 1).

Further, in the structure of claim 1, the invention of claim 2 is such that the stopper means or the ball that rotates integrally with the blade is arranged such that the ball can be engaged with the ball at a plurality of rotational positions of the blade. It is composed of a plurality of recesses provided in the stile along a rotation locus and a spring that biases the ball in a direction to engage the recess.

Furthermore, in the structure of claim 1 or 2, the invention as claimed in claim 3 is such that the left and right frames are constituted by a frame body and a blade attachment body that is detachably attached to the inner surface of the frame body. Both ends of each blade are pivotally attached to the blade mounting body.

On the other hand, the invention according to claim 4 is such that in the configuration according to any one of claims 1 to 3, each blade is connected to be integrally rotatable by a connecting rod.

Moreover, the invention according to claim 5 is the configuration according to claim 4, in which the blades are connected at their mutual ends by connecting rods.

According to a sixth aspect of the invention, the blades are connected to each other at their central portions by a connecting rod.

Further, the invention of claim 7 provides the configuration according to any one of claims 4 to 6, in which each blade is located at a position away from the center of gravity so that a rotational moment in a direction opposing the weight of the connecting rod acts on each blade. It is pivoted to the left and right frames.

[Effect]

According to the structure of claim 1, since each blade is rotatable around the horizontal axis, it is possible to adjust the direction and angle of inclination of each blade and the degree of opening. Therefore, it is possible to change the amount of ventilation and lighting conditions depending on the season, temperature and humidity conditions, etc., and change the outdoor scenery through the shutters as desired.It is also possible to omit curtains, etc. Since it takes advantage of the characteristics of shutters, it also has the function of a blind.

Further, according to the second aspect of the invention, in which a Hall-type stopper mechanism is used as the stopper means, the blades can be automatically fixed at a plurality of rotational positions, and the rotational resistance of the blades can be minimized.

By the way, in shutters in which the blades are rotatably pivoted as in the present invention, wear occurs at the blade pivoting portion, requiring parts to be replaced, and for this reason, the blades must be removable. .

In this case, according to the structure of claim 3, the blade mounting body to which each blade is attached is detachable from the frame body fixed to an opening such as a window, so each blade can be attached and detached very easily. becomes.

On the other hand, according to the configuration of claim 4, in which the blades are connected so as to be integrally rotatable by the connecting rod, all the blades can be rotated synchronously by operating the connecting rod, thereby simplifying the adjustment operation.

Moreover, according to the structure of claim 5, in which the blades are connected at their ends by a connecting rod, it becomes possible to arrange the connecting rod between the blade and the frame. Therefore, since the amount of protrusion of the connecting rod toward the front side of the door can be reduced, there is no risk that the connecting rod will get in the way, especially in the case of sliding shutters.

On the other hand, according to the structure of claim 6 in which the blades are connected to each other by a connecting rod at their central portions, the rotational operation force of each blade acts equally on the left and right sides, so that the rotational operation of the blades is performed smoothly.

Further, according to the configuration of claim 7, in which each blade is pivotally mounted in a state where a rotational moment acting in a direction opposing the weight of the connecting rod acts on each blade, the weight of the connecting rod can be shared by the rotational moment. The load on the stopper means for holding the rotational position is reduced. Therefore, since the holding force of this stopper means is small, the number of stopper means installed can be reduced.

〔Example〕

1st Embodiment (See Figures 1 to 7) In the figure, 1 is an upper stile, 2 is a lower stile, 3 is a left stile, and 4 is a pomegranate, which can be attached to openings such as windows and doorways. A picture frame-like frame A is assembled, and a plurality of upper and lower blades 5 are horizontally attached between the left and right frames 3 and 4 within the frame A to form a shutter.

The left and right frames 3 and 4 include frame bodies 3a and 4a that are fixed to the edge of an opening (door frame) such as a window, and the frame body 3a.

The vane attachment bodies 3b and 4b are detachably attached to the inner surface of the blade 4a with a plurality of screws 6.

Pin receivers 7 are embedded in the blade attachment bodies 3b and 4b at regular intervals above and below, and the pins 8 planted on both the left and right end surfaces of each blade 5 are rotatably fitted into the pin receivers 7. , each blade 5 is rotatably mounted around this pin 8 between the left and right frames 3.4.

On the other hand, on the inside of the frame bodies 3a, 4a of the left and right frames 3, 4, and on the front side of the blade attachment bodies 3b, 4b, there are left and right connecting rods 9.
．． 9 are arranged, and each blade 5... is connected to each other at the left and right ends by the connecting rods 9, 9 so as to be integrally rotatable.

In addition, each blade 5... and the connecting rods 9, 9 are connected so as to be relatively rotatable by a pin 10 planted on the side of the blade 5 and a pin receiver 11 buried on the side of the connecting rod 9.9. ing.

Also, the right side connecting rod 9 (the left side or both side connecting rods are also possible)
A bar 12 for operation is attached to the front of the
By raising and lowering the right side connecting rod 9, each blade 5 is configured to be able to rotate synchronously in the same direction and at the same angle.

In addition, the edge frame A and each blade 5..., the connecting rods 9, 9 are as follows:
Usually, the shutters are made of wood to maintain the unique look of the shutters, but they may also be made of plastic or the like with a wood grain finish on the surface.

On the other hand, a ball-type stopper mechanism 13 for holding each blade 5 at a plurality of rotational positions is provided between opposing surfaces of the right connecting rod 9 and the pomegranate main body 4a at approximately the center in the height direction. ing.

As shown in FIGS. 2 to 4, this ball type stopper mechanism 13 includes a ball case 14 embedded in the connecting rod 9,
A hole 15 is fitted into the ball case 14 with a half protruding outward, and a plurality of holes (fourth (Explained in five cases according to the example in the figure)
and a recess 17-. Reference numeral 18 denotes a plate body provided with the recesses 17.

As shown in FIG. 4, the recesses 17 are provided at equal intervals of approximately 1200 mm along the rotation locus of the hole 15, and as the blades 5 rotate, the balls 15 is selectively elastically engaged with this recess 17, so that each blade 5 can be moved to three positions, namely, the horizontal (fully open) position shown in FIGS. 1 to 5, and the horizontal angle of 30 degrees. ' is maintained at the upward and downward intermediate positions and at the maximum upward and downward tilt positions of 60° with respect to the horizontal as shown in FIG. 6.7.

Therefore, in this shutter, the direction and angle of inclination and opening degree of each blade 5 can be adjusted in three stages, so the amount of ventilation can be adjusted according to seasonal changes, temperature and humidity conditions, etc. You can adjust the lighting conditions and change the outdoor scenery through the shutters as desired.

Further, at the maximum tilt position shown in FIGS. 6 and 7, the amount of daylight is minimum, and especially at the maximum upward tilt position shown in FIG. 6, the amount of sunlight incident is extremely small, so there is no need to provide a curtain on the inside of the door.

Furthermore, since each of the blades 5... is synchronously rotated in the same direction and at the same angle by the connecting rods 9, 9, the adjustment operation is easier than when operating each blade separately.

In addition, since the ball-type stopper mechanism 13 is used, each blade 5 can be reliably held at each rotating position, and the balls 15 elastically move in and out to engage and disengage from the recesses 17. Therefore, the rotational resistance of the blades 5 can be minimized, and adjustment operations can be performed easily.

Furthermore, according to this first embodiment in which the blades 5 are connected at their ends by a connecting rod 9.
, 9 within the depth dimension of the left and right frames 3.4, the amount of protrusion of the operating bar 12 from the edge frame A (I in FIG. 3) can be reduced. Therefore, even when this shutter is used as a sliding door, the connecting rods 9.9 and the bar 12 do not get in the way of the sliding door. In other words, it is suitable as a sliding door.

On the other hand, in the case of this shutter in which the blades 5... rotate, wear occurs at the blade pivoting part and the connecting part between the blades 5... and the connecting rods 9, 9 due to long-term use, so it is necessary to It is necessary to replace the pin receiver 7.11 or the pin 8.10.

In this case, in this shutter, the left and right frames 3°4 are constituted by the seed bodies 3a, 4a and the blade attachment bodies 3b, 4b detachably attached to the seed bodies 3a, 4a, so that the above-mentioned parts When replacing the blade attachment bodies 3b and 4b on both sides,
are removed from the seed bodies 3a, 4a and taken out from the edge frame A along with the blades 5..., and in this state, the blades 5... and the blade attachment bodies 3b, 4b are separated and the necessary parts are replaced,
It can be reattached to the edge frame A by reversing this procedure.

Therefore, compared to the case where the blades 5 are directly attached to the frame of a conventional shutter (corresponding to the seed bodies 3a and 4a in the embodiment), parts replacement is much easier.

Second embodiment (see Figures 8 to 10) Only the differences from the first embodiment will be explained.

In this second embodiment, the blades 5 are connected to each other at their central portions by a connecting rod 19 so as to be integrally rotatable.

To explain this connection structure in detail, there are U-shaped connection pins 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 20, 4, 20, 20, 20, 20, 20, 20, 20, . 21... is implanted, and this connecting pin 2
By connecting the 0.21s in a chain-like manner,
Each blade 5... and a connecting rod 19 are pivotally connected.

In the figure, 22.22 is a pin for pivoting the blade 5 to the blade attachment bodies 3b, 4b, and 23.23 is a pin receiver.

According to this second embodiment, since the operating force of the connecting rod 19 acts equally from the center of each blade 5 on the left and right sides, the blades 5...
Adjustments can be made smoothly with little force.

In addition, in this configuration, the connecting rod 19 projects forward of the edge frame A, and since the connecting rod 19 can be directly raised and lowered, there is no need to provide any operating bar. Also,
In the case of the second embodiment, a ball-type stopper mechanism (not shown) is provided between a specific end face of the blade 5 (usually at the middle part in the height direction) and the blade attachment bodies 3b, 4b.

Third Embodiment (See Figure 11) In the case of this shutter in which each blade 5... is connected by a connecting rod 9.19, the weight of the connecting rod 9.19 is always attached to each blade 5. It acts as a turning force in the direction of arrow A in the figure. Therefore, the ball type stopper mechanism 13 in both the first and second embodiments has a holding force sufficient to overcome this rotating force and reliably hold the blades 5 in the set position. Is required.

On the other hand, in the third embodiment, each blade 5 is connected to each blade 5 by being pivotally mounted at a position shifted downward in the inclined state from the blade center (center of gravity). It is configured so that a rotational moment in the direction of the arrow head counteracts the weight of the rod (rotation force in the direction of arrow A).

Although FIG. 11 illustrates the configuration of the second embodiment in which the blades 5 are connected to each other at their central portions by a connecting rod 19, the configuration of the first embodiment is also similar to that described above. can do.

By doing this, the stopper mechanism (
(not shown in FIG. 11), the holding force of the mechanism can be reduced accordingly. Therefore, for example, even if it is necessary to install the stopper mechanism at multiple locations in the first and second embodiments, by adopting the configuration of the third embodiment, the number of stopper mechanisms installed can be reduced to about one location. This reduces costs and makes assembly easier. Alternatively, the holding force of the stopper mechanism may be weakened to further reduce the rotational resistance of the blades 5.

In addition, the weight distribution of each blade 5... can be made different on both sides with respect to the blade center, the blade gravity center can be shifted from the blade center, and the blade 5 can be pivoted at the center (a position away from the gravity center). The same effect as above may be obtained by

Other Embodiments (I) The stopper means can be modified in various ways other than the ball type stopper mechanism 13 used in the above embodiments, for example, a gear having a plurality of recesses in the circumferential direction on the outer periphery of the blade pivot pin. A rotary ring of the shape is provided to be able to rotate integrally with the blade, while a locking member made of a leaf spring is provided on the stile side and has a protrusion that elastically engages with the above-mentioned recess. It may also be configured to hold the stage in its rotational position (Ao(n
) In the above embodiment, the left and right frames 3.4 were composed of the frame bodies 3a, 4a and the blade attachment bodies 3b, 4b.
, 4 may be formed from a single component corresponding to the frame bodies 3a, 4a of the above embodiment.

(III) In the above embodiment, the opening degree is minimized when the blades are inclined at an angle of 60° with respect to the horizontal, or a fully closed state in which adjacent blades are in contact with each other may be obtained.

〔Effect of the invention〕

As described above, according to the present invention, since each blade is pivotally mounted between the left and right frames so as to be rotatable around a horizontal axis, it is possible to adjust the direction and angle of inclination of each blade and the degree of opening.

Therefore, it is possible to change the amount of ventilation and lighting conditions depending on the season, temperature and humidity conditions, and change the outdoor scenery as desired.It is also possible to omit curtains, etc. It is designed to take advantage of these characteristics while also having the functionality of a blind.

Further, according to the second aspect of the invention in which a ball-type stopper mechanism is used as the stopper means, the blade can be automatically fixed at a plurality of rotational positions, and the rotational resistance of the blade can be minimized.

Further, according to the invention of claim 3, the stile is constituted by a stile main body fixed to an opening such as a window, and a blade attachment body detachably attached to the inner surface of the stile body, and the blade attachment Since each blade is pivotally attached to the body, it is possible to easily replace parts in response to wear of the blade pivoting portion.

On the other hand, according to the invention according to claim 4, in which the blades are connected so as to be integrally rotatable by the connecting rod, all the blades can be rotated synchronously by operating the connecting rod, thereby simplifying the adjustment operation.

Moreover, according to the invention of claim 5, in which the blades are connected at their ends by a connecting rod, it is possible to arrange the connecting rod between the blade and the frame. Therefore, since the amount of protrusion of the connecting rod toward the front side of the door can be reduced, there is no risk that the connecting rod will get in the way, especially in the case of sliding shutters.

On the other hand, according to the invention according to claim 6, in which the blades are connected to each other by a connecting rod at their central portions, the rotational operation force of each blade acts equally on the left and right sides, so that the rotational operation of the blades is performed smoothly.

Further, according to the invention of claim 7, in which each blade is pivotally mounted in a state in which a rotational moment in a direction opposing the weight of the connecting rod acts on each blade, the weight of the connecting rod can be shared by the rotational moment, so that the blade can The weight burden on the stopper means for holding the rotation position is reduced. Therefore, since the holding force of this stopper means is small, the number of stopper means installed can be reduced.
