Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shutter having a structure that is disposed, for example, at a doorway of a garage or the like so that when the shutter curtain is opened, the shutter curtain is horizontally stored above.
[0002]
[Prior art]
A shutter disposed at an entrance of a garage or the like is normally connected to a vertical guide rail and disposed along a ceiling surface without providing a shaft for winding a shutter curtain above the entrance / exit portion. The shutter curtain is moved to the rail so as to be stored.
[0003]
Conventionally, such shutters are disclosed in Japanese Utility Model Publication Nos. Sho 56-15352 and 64-50594, and a wheel is provided at a connecting portion between a vertical rail and a horizontal rail. The shutter curtain is moved up and down by the movement, and one end is fixed to the end of the horizontal rail, and a tension spring disposed in the horizontal rail is connected to the upper end of the shutter curtain. It is designed to help lift, that is, open and store.
[0004]
[Problems to be solved by the invention]
However, in the conventional shutter described above, the length of the horizontal rail that stores the shutter curtain that closes the entrance / exit portion when the shutter is opened is the length that is the height of the shutter curtain, and the tension spring is in a contracted state by pulling up the shutter curtain. Since this is the total length of the tension springs, the guide rail has a shape whose depth is longer than the height of the entrance / exit part.
[0005]
Therefore, when the private car stored in the garage where this shutter is installed has an external shape with a short ratio of length (overall length) to height (vehicle height), the length of the tension spring should be considered. Therefore, the depth of the garage becomes longer than the height of the entrance / exit, resulting in a disadvantage that space saving cannot be achieved.
[0006]
In addition, each guide rail has a U-shaped cross-section with an opening on one side facing each other, and since the side edge of the shutter curtain is inserted and supported, the respective opening portions are disposed facing each other. The tensile coil spring arranged in the horizontal rail of the guide rail is exposed, and there is a drawback that the design is poor.
[0007]
In order to solve the above problems, an object of the present invention is to provide a shutter that can save space in the depth direction and has a good appearance without exposing a spring.
[0008]
[Means for Solving the Problems]
Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.

One end 21 a is connected to the upper ends of the left and right edge portions of the shutter curtain 2, the middle is connected to the pulley 16 and the folding pulley 20 through the passage port 12, and the other end 21 b is the pulley 16 in the case 11. And a flexible long body 21 fixed in the vicinity of the belt. The folding pulley 20 is slidable along the horizontal rail 9 in the case 11.
[0009]
The shutter 1 according to the present invention is characterized in that the case 11 is formed of a long box-like case that is integrated with the horizontal rail 9 and has the upper surface of the horizontal rail 9 as a bottom surface.
[0010]
The desired position within the range between the end 9a and the end 9b of the horizontal rail 9 where the one end 17a of the tension spring 17 is fixed is preferably the outer surface of the horizontal rail 9.
[0011]
With the above configuration, the shutter 1 of the shutter 1 is supported by the left and right guide rails 7 at the left and right edge portions, and moves up and down between the guide rails 7 and between the vertical rails 8. Then move horizontally.
As the shutter curtain 2 moves, the flexible elongated body 21 connected to the shutter curtain 2 is contracted by the pulling force of the tension spring 17 so that the shutter curtain 2 moves without loosening. The opening / closing operation of the shutter curtain 2 is assisted by the pulling force of the tension spring 17.

[0013]
First, as shown in FIG. 1, the shutter 1 is disposed at an entrance / exit portion of a garage 30 installed outdoors, and opens / closes the entrance / exit.
The garage 30 includes four support columns 31 and 32 and a roof portion 33 that connects the upper ends of the support columns 31 and 32 and covers the top.
[0014]
Next, the shutter 1 of the present embodiment is roughly configured by a shutter curtain 2, a pair of left and right guide rails 7, a pulley 16, a tension spring 17, and a chain 21 as a flexible long body. .
[0015]
In this embodiment, as shown in FIGS. 1 to 3, the shutter curtain 2 is composed of a grill shutter curtain in which rod-like members 3 such as hollow pipes are connected in a vertical direction with links 4 at a predetermined pitch, An inverted T-shaped draining slat 3a is connected, and a square pipe-shaped suspension member 5 is connected to the upper edge.
Further, rolling rollers 6 are disposed at both ends of each rod-like member 3 of the shutter curtain 2.
[0016]
Next, the pair of left and right guide rails 7 are each composed of a vertical rail 8 and a horizontal rail 9, and an upper end 8a of the vertical rail 8 and a front end 9a of the horizontal rail 9 are curved in a quarter circle. The curved rails 10 are connected to each other and formed in a substantially L shape.
[0017]
Further, as shown in FIG. 4, the guide rails 7 are formed in a substantially U-shaped cross section with one side opened, and the opening portions 7a are arranged to face each other.
[0018]
The vertical rail 8 and the horizontal rail 9 are formed in substantially the same scale, and the vertical rail 8 is formed integrally with the left and right columns 31 in front of the garage 30, and the horizontal rail 9 is formed in the ceiling portion of the garage roof portion 33. It is arranged in the shape of a beam on the left and right edges.
[0019]
Further, a rectangular box-like long case 11 which is integrated with the horizontal rail 9 and has the upper surface of the horizontal rail 9 as a bottom surface is disposed along the horizontal rail 9 on the outer upper surface of the horizontal rail 9. The hollow portion of the case 11 communicates with the passage port 12 formed on the upper surface of the end 9b of the horizontal rail 9.
[0020]
Then, rolling rollers 6 at both ends of the shutter curtain 2, that is, both ends of each rod-shaped member 3 are inserted into and supported by each guide rail 7, and are movable between both guide rails 7. Further, both ends of the suspension base member 5 are also moved in the guide rail 7.
[0021]
As shown in FIG. 2, side plates 13 are respectively disposed on the outer side surfaces of the curved rails 10 of the guide rails 7, and the side plates 13 are hollow in the vicinity of the inner side of the curved rails 10. A pipe-shaped shaft 14 is provided.
[0022]
The shaft 14 incorporates an electric motor (not shown) serving as a drive source, and cam plates 15 are attached to both ends of the shaft 14.
The cam plate 15 is formed so that the radius from the center coincides with the curvature of the curved rail 10, and the engagement recess 15 a set at the connection interval of the rod-like members 3 of the shutter curtain 2 has an outer periphery. It is the gear-shaped member formed in this.
[0023]
Next, the pulley 16 is disposed at the passage opening 12 at the end 9b of the horizontal rail 9 of each of the left and right guide rails 7, and is pivotally supported by each.
The axial direction of these pulleys 16 is set to be parallel to the shutter curtain 2.
[0024]
Next, the tension spring 17 is constituted by a pair of left and right tension springs, and one end 17a is fixed to the end 9a side of the horizontal rail 9 in each case 11 via a mounting bracket 18, and these cases 11 is disposed along the horizontal rail 9. A slide bracket 19 is connected to the other end 17 b of the tension spring 17. A folding pulley 20 is pivotally supported on the slide bracket 19.
[0025]
The slide bracket 19 is slidable along the horizontal rail 9 in the case 11 together with the folding pulley 20.
[0026]
Next, the chain 21 as a flexible long body is comprised by a pair, and as shown in FIG. 2, each end 21a is connected with the upper end of the shutter curtain 2 in the horizontal rail 9, and the suspension base. The other end 21b is connected to both ends of the member 5, and the other end 21b is positioned and fixed on the top of the pulley 16 located at the end 9b of the horizontal rail 9 in the case 11 as shown in FIGS. Has been.
[0027]
The middle portion of the chain 21 is engaged with the pulley 16 in the horizontal rail 9, passes through the passage port 12, and is engaged with the folding pulley 20 of the tension spring 17. It is stretched so that it may be located in the horizontal rail 9 and the case 11 so that it may become a shape.
[0028]
Therefore, according to the shutter 1 configured in this way, the shutter curtain 2 is supported by the left and right guide rails 7 at the left and right end edges, and is movable between the guide rails 7 and is built in the shaft 14. Each of the rod-like members 3 meshed with the engaging recess 15a of the cam plate 15 is sent by the cam plate 15 that is rotated in both the forward and reverse directions by the driven source, whereby the shutter curtain 2 is moved between the left and right guide rails 7. Are moved up and down between the vertical rails 8 and moved horizontally between the horizontal rails 9.
When the shutter curtain 2 moves, the rolling rollers 6 at both ends roll in the guide rail 7 so that the movement is performed smoothly.
[0029]
As the shutter curtain 2 moves, the chain 21 connected to the suspension member 5 of the shutter curtain 2 is contracted by the pulling force of the tension spring 17 so that the shutter curtain 2 moves without loosening. The chain 21 moves from the horizontal rail 9 into the case 11, and the pulling force of the tension spring 17 supplements the driving force of the driving source when the shutter curtain 2 is opened, thereby assisting the opening / closing operation.
[0030]
And according to this shutter 1, the vertical rail 8 of the guide rail 7 and the horizontal rail 9 are formed in substantially the same scale so that only the shutter curtain 2 comprised in the height for the closing of the entrance / exit part may be accommodated. Therefore, the height and depth length of the entrance / exit portion are set to be substantially the same length, thereby eliminating the components in the depth direction and saving space.
[0031]
Further, the tension spring 17 for assisting the raising / lowering (opening / closing) operation of the shutter curtain 2 is not provided in the horizontal rail 9 for housing the shutter curtain 2, and the end 9 a and the end of the horizontal rail 9 outside the horizontal rail 9 are disposed. 9b, in this embodiment, the tension spring 17 is not exposed from the horizontal rail 9 by being arranged at the upper portion along the horizontal rail 9 outside the horizontal rail 9 in this embodiment. As a result, the tension spring 17 is housed in the case 11 disposed along the horizontal rail 9, so that the appearance is improved.
[0032]
Further, the chain 21 related to the tension spring 17 is stretched in a substantially S shape via the pulley 16 and the folding pulley 20, and constitutes a two-unit single pulley. The pulling force of the tension spring 17 can be set to be smaller than the weight, and the spring can be configured with a shorter spring than the conventional one. This also makes it possible to save space.
[0033]
In the above-described embodiment, the example in which the flexible long body 21 is configured as a chain has been described. However, the flexible long body 21 may be configured with a belt as illustrated in FIG. You may comprise by the member which has.
[0034]
In the above-described embodiment, the example in which the tension spring 17 is disposed on the upper portion of the horizontal rail 9 so as to be parallel to the horizontal rail 9 has been described. However, the case 11 is disposed on the lower portion of the horizontal rail 9. May be.
[0035]
Further, in the above-described embodiment, the example in which the shutter curtain 2 is configured by the grill shutter has been described. However, the shutter curtain 2 may be configured by a slat curtain in which strip-shaped slat members are connected. Even when applied to a panel shutter configured as described above, the above-described effects can be obtained.
In the case of the slat curtain and the panel plate, rolling rollers 6 are disposed at both ends supported and guided by the guide rail 7 so that they can move smoothly in the guide rail 7.
[0036]
Further, in the above-described embodiment, the example in which the shutter curtain 2 is opened and closed by rotating the cam plate with a drive source such as an electric motor has been described. It is good also as a structure opened and closed.
[0037]
【The invention's effect】
As described above, in the shutter according to the present invention, the vertical rail and the vertical rail so as to accommodate only the shutter curtain configured to have a height for closing the entrance / exit portion in the garage or the like which is the length of the vertical rail of the guide rail. The horizontal rail is formed to be approximately the same size, and only the shutter curtain is stored in the horizontal rail, and the tension spring that pulls the shutter curtain is within the case within the range between the tip and end of the horizontal rail outside the horizontal rail. By adopting the location, it is possible to realize a garage in which the height of the entrance / exit portion and the depth length are substantially the same length, thereby obtaining the effect of saving space in the depth direction.
[0038]
In addition, by adopting a configuration that does not include a tension spring that assists the raising / lowering (opening / closing) operation of the shutter curtain in the horizontal rail that houses the shutter curtain, the tension spring is not exposed from the horizontal rail, so the appearance is good. There is an effect that the designability is improved.
[0039]
In particular, the position of the tension spring is arranged along the horizontal rail in a hollow case provided integrally therewith, so that the entire mechanism including the shutter mechanism can be made compact. Therefore, the installation work is facilitated, the space can be saved, and the appearance is improved.
[0040]
In addition, since the tension spring is disposed in an integral case along the horizontal rail, the chain associated with the tension spring is substantially S-shaped via a passage opening that connects the horizontal rail and the case, a pulley, and a folding pulley. Because the two sets of single pulleys are constructed, the pulling force of the tension spring can be set smaller than the weight of the shutter curtain, and it can be configured with a shorter spring than before. There is also an effect that space saving can be achieved.
