Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connected shutter made by connecting a plurality of shutters in a series.

[Prior art and problems to be solved by the present invention]

In general, this type of storm door is different from normal sliding doors in that it runs on the same rail.
Furthermore, when storing a storm door in a door pocket, it must be moved in the lateral direction (thickness direction of the storm door) orthogonal to the direction of movement during opening and closing. For this reason, the running rail is eliminated inside the door pocket, but this method has disadvantages such as it is difficult to pull out the leading shutter from the door compartment, and sometimes the leading shutter goes deep into the door compartment, making it difficult to remove. There is. So, in the 1980s,
-As shown in Publication No. 40689, the leading shutter is a top-hung type with a guide rail extending into the door pocket, and the trailing shutter is a door roller type in which the door roller rail is notched at the entrance of the door pocket, so that even when the leading storm door is stored in the door pocket, There is one that prevents the leading shutter from coming off the guide rail. However, this does not require separate dedicated rails for the upper and lower frames of the opening, and the shutter itself also needs to be prepared in both a top-hung type and a door roller type, making product management complicated. turned into
Moreover, since it is a combination of a top hanging type and a door roller type, there is a drawback that vertical misalignment inevitably occurs between the two, and further improvements are needed.

[Means to solve problems]

The present invention was devised in view of the above-mentioned circumstances with the aim of providing a connecting shutter that can eliminate these problems, and is intended to provide a connecting shutter made by connecting a plurality of shutters in a series. Each of the above-mentioned shutters is of a top-hung type, and the running rails for the leading shutter and the trailing shutter are extended to the inside of the door pocket, and those for the trailing shutter are cut out at the entrance of the door pocket. The trailing storm door running rails are laid in a parallel manner, and the trailing storm door running rails are arranged on the side from which the trailing storm shutters stored in the door pockets are fed sideways with respect to the leading storm door running rails. .

With this configuration, the present invention allows for easy lateral movement of the connected shutters when storing the door bag, and prevents the leading shutter from coming off the hanger rail, even though the connected shutters are all top-hung type. It is.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings. In the drawings, 1 and 1a are the leading shutter installed in the upper and lower frames 2 and 3, respectively, and a plurality of other trailing shutters, and both the shutters 1 and 1a are of the top-hung type, as will be described later. , so as to roll on running rails 2a and 2b provided on the upper frame 2. Each of the shutters 1, 1a is connected via a connector 5 provided on the leading shutter side, but this connector 5 is connected to a support plate 5c integrally provided on the door end side of the leading shutter. The swinging arm 5d is pivotally connected to the swinging arm 5d so as to be swingable via the support shaft 5b, and the connecting roller 5a provided at the tip of the outer swinging arm 5d runs within the connecting rail 6 provided on the trailing shutter. There is. Further, the front and rear ends of the shutters 1 and 1a have inclined surfaces 4 and 4a that correspond to each other, and these inclined surfaces 4 and 4a and the connector 5 allow the shutters 1 and 1a to be arranged in parallel in the door pocket 7. It will be stored away as it ages.

Reference numeral 8 denotes an electric motor disposed on the upper frame 2 side of the door pocket 7, and a geared wire 9 is meshed with a sprocket 8a that rotates in conjunction with the electric motor 8. This geared wire 9 is a flexible wire with a spiral groove formed on its circumferential surface, and is driven by the forward and reverse drive of the electric motor 8 to a geared wire rail provided on the upper frame 2 in parallel with the traveling rail 2a. 2c, but the leading shutter 1 is attached to the geared wire 9 via a runner 10, and as the geared wire 9 moves, the leading shutter 1 is
move integrally, thereby opening and closing the opening.

Approximately L-shaped mounting brackets 12 are integrally fixed to the upper stile 11 of the leading shutter 1 and the trailing shutter 1a, respectively, and a substantially L-shaped support 13 is attached to the mounting bracket 12 of the leading shutter. One side of is fixed integrally. On the other side of the support 13, a running roller 14 and a steadying roller 15 are rotatably supported at a slightly higher position than the running roller 14. On the other hand, one side of a support 16 bent into a crank shape is integrally fixed to the mounting bracket 12 of the trailing shutter, and a running roller 17 is rotated on the other side of this support 16. These running rollers 14, 17 are arranged so that the running roller 17 of the trailing shutter 1a is located on the outdoor side. Further, the upper frame 2 is provided with a running roller 1 at a position below the fitting portion of the geared wire 9.
The above-mentioned leading shutter running rail 2a and trailing shutter running rail 2b are formed adjacent to each other in parallel so that the leading shutters 4 and 17 run separately. The leading shutter running rail 2a, on which the leading shutter roller 14 runs, extends to the inside of the door pocket 7, but the trailing shutter running rail 2b, on which the trailing shutter roller 17 runs, runs at the entrance of the door pocket 7. A guide surface 2d is formed which is notched at the front entrance and whose end is inclined to become lower toward the door pocket 7 side. Reference numeral 20 denotes a sliding body provided on the lower surface of the lower stile 18 of the trailing shutter 1a, and the sliding body 20 slides on the lower frame 3 while the running roller 17 of the trailing shutter 1a is rolling on the running rail 2b. Although it is spaced apart from the bottom surface 3a, when the trailing shutter 1a moves to the door pocket 7 side and the running roller 17 comes off the running rail 2b as described above, the sliding body 20 moves to the lower frame guide provided on the lower frame 3. 3b to slide on the bottom surface 7a of the door pocket 7, and the subsequent shutter 1a slides on the bottom surface 7a of the door pocket 7.
By sliding, the shutter 1a is stored in the door pocket 7, and when it is almost stored, the trailing shutter 1a is moved to the running rail 2b.
In this way, the succeeding shutters 1a or the leading shutters 1 are sequentially stored in the door pocket 7 due to the cross-feeding action in the state in which they are removed from the shutters. In this case, the sliding body 20 has a door bag bottom groove surface (formed higher than the bottom frame bottom surface 3a and flush with the bottom frame guide 3b) 7c.
It is designed to slide on a guide portion 7b provided at approximately the same height as the bottom surface 3a of the lower frame.

On the other hand, when closing the opening, the leading shutter 1 is pulled out from the door pocket 7 by forced feeding of the geared wire 9, and the trailing shutters 1a are subsequently pulled out one after another, but in this case, Subsequent shutter 1a
Immediately after leaving the door pocket 7, the running roller 17 comes to roll on the running rail 2b as it is guided by the trailing storm door running rail guide surface 2d, and from then on it starts to open and close in a hanger state. There is.

In the embodiment of the present invention constructed as described above, the opening and closing of the opening is performed continuously and automatically by operating a push button switch (not shown). In this embodiment, each of the shutters 1, 1a are all top-hung type, so it is similar to the conventional case where the leading shutter was a top-hung type and the trailing shutter was a door roller type.
The running rails 2a and 2b can be integrally formed using a molded material or the like, without providing separate dedicated running rails. Moreover, since they are of the same top-hung type, the main body of the shutter can be of the same standard as long as the running positions of the running rollers 14 and 17 are shifted, and the structure is therefore simplified and product management is also easy. In addition, there is no possibility that there will be any vertical deviation between the leading shutter 1 and the trailing shutter 1a.

Moreover, in this embodiment, the trailing storm door running rail 2b is arranged on the door pocket 7 side with respect to the leading storm door running rail 2a, and is cut out at the entrance of the door pocket 7, so that the trailing storm door running rail 2b is notched at the entrance of the door pocket 7. Smooth traversing operation can be performed without causing any hindrance when traversing within the door pocket 7. Even when all the shutters are stored in the door pocket 7, the leading shutter 1 is moved by the running roller 14.
Since it is located on the running rail 2a that extends into the door pocket 7, there is no chance of it falling sideways, and when closing the shutter, the leading shutter 1 is guided as it is on the running rail 2a. Since it is pulled out in the same state, it can be automatically closed very smoothly.

In this embodiment, the guide surface at the end of the rail for the trailing shutter is sloped and is configured to guide the traveling roller to the running rail, so the trailing shutter cannot run inside the door pocket. Although the rollers are removed from the running rail and the sliding body slides on the bottom of the door, it is possible to smoothly and reliably transform the succeeding storm door into a top-hung type when it is closed.

[Effect]

Although all the shutters are top-hung and the shutter body is of one type, and it is possible to eliminate vertical deviation, the leading shutter runs on a running rail that extends into the door pocket, and the trailing shutter runs on a running rail that extends into the door pocket. The shutter runs on a running rail that is cut out at the entrance of the door pocket and is arranged in the cross-feeding direction.Therefore, even when inside the door pocket, the leading shutter will not come off the running rail, allowing for smooth and reliable opening and closing. In addition to being able to operate the shutter, it is also possible to move the trailing shutter horizontally to the door bag head plate side without being obstructed by the running rail, making it possible to smoothly and reliably move the shutter even if it is all suspended from above. It is capable of automatic continuous opening and closing operation.
