Description

[Detailed description of the invention] [Industrial field of application] The present invention aims to improve the hanging structure of a folding horizontal shutter, and more specifically, to improve the suspension structure of a folding type horizontal shutter. Even if it is, the error can be absorbed and incorporated exactly there,
Moreover, it relates to a practical side-pull shutter that has little inertial reaction when opening and closing the shutter.

[Conventional technology and technical issues to be solved]

In recent years, the folding type horizontal-pulling shutter shown in Figure 1 has come into widespread use, but the problem when installing such horizontal-pulling shutters is that they are standardized and cannot be manufactured at the factory. When attempting to actually construct this type of horizontal shutter, which is mass-produced, on-site, the specific circumstances unique to the building (for example, the client's requests, the designer's design, design philosophy, site conditions, etc.) ), the size of the building is not necessarily such that it will fit perfectly into the actual construction opening, and as the building itself deteriorates over time, it may become misaligned and the part where the shutter is installed may become distorted. It is easy for gaps to form, which impedes airtightness when the door is closed.

Moreover, in the case of this type of horizontal shutter, as shown in Figure 1, the wide space between the pillars to which the hanging frame A and the doorstop frame B are attached is sealed off airtight to withstand large wind pressure. Because of this, the entire shutter has to be structurally quite heavy, which increases the moving inertia when the shutter is opened and closed, and acts directly on the suspension frame A, resulting in sudden shock. The situation is such that there is a risk of damage due to severe impact.

The present invention solves the above-mentioned drawbacks of conventional folding type horizontal shutters by making clever improvements to the suspension part of the shutter. Even if there is an error or a deviation occurs later,
It is possible to absorb such errors and deviations, and even if the shutter is roughly pulled sideways when the door is closed, it is practical because it buffers the movement inertia and will never damage the hanging frame. The objective of the present invention is to provide a horizontal pull shutter that is highly durable.

[Technical means adopted to solve the problem]

The means adopted by the present inventor to solve the above technical problem will be explained with reference to the attached drawings.
It is as follows.

That is, the present invention has a plurality of vertically long shutter pieces 1,
1... are foldably connected by predetermined joints 2, 3, and 4, and are configured to be foldable and openable while hanging from a hanger rail 9 installed on the lintel side. The subject of improvement is the horizontal shutter, and the shutter pieces 1, which make up the horizontal shutter,
1. Hang the joint stile 6 connected to the side edge of the shutter piece 1 that is located closest to the hanging base side so that it can be slid out from the opening 51 of the hanging frame 5 toward the door stop. By adopting the method of clearance connection to the original frame 5, even if there is some error between the opening of the building and the opening of the building, or even if a deviation occurs later, the error or deviation can be eliminated. On the other hand, the hooking ribs 62, 62' on the rear side of the hanging joint stile 6
By interposing a buffer spring 63 at the contact position between the shutter and the detachable stop plate 53 provided in the opening 51 of the hanging frame 5, it is possible to prevent the shutter from being violently moved when the door is closed. Even if it is pulled sideways, the movement inertia at that time is buffered so that the suspension frame will never be damaged.

〔Example〕

Hereinafter, the present invention will be described in more detail based on embodiments shown in the accompanying drawings.

As shown in FIG. 2, the folding type horizontal shutter T connects each shutter piece 1, 1... with a joint with a stopper 2, 2..., a hanging type joint 3, 3...,
and intermediate joint joints 4, 4..., which are foldably connected, and one side edge of the shutter T is fitted into the hanging frame 5 and connected to the hanging frame 6.
On the other hand, a pull joint stile 7 is connected to the other side edge, and a hanger roller 8,
Hanger rail 9 installed on the lintel side with 8 installed
It is suspended so as to be guided by the inner rail grooves 10, 10.

On the other hand, a slider 12 is attached to the lower part of the joint joints 3, 3, etc. of the same number, and the slider 12 is inserted into and guided by the lower rail 11 arranged on the sill side, and the pull frame 7 is moved to the door stop. The shutter T is closed by pulling it in the direction of the frame 13, and conversely, by pulling the pull joint stile 7 in the direction of the hanging frame 5, each shutter piece 1, 1... is folded and stored in the case 14, and is configured to be opened.

By the way, in the case of the conventionally well-known side-pull shutter, if there is an error between the dimensions of the built-in opening and the size of the side-pull shutter, when the shutter T is closed, the pull stile 7 will not close to the door. Current slot 1
If the shutter pieces 1, 1, etc. do not come into contact with the joints 3, or are too large, the shutter pieces 1, 1, etc. will not fully extend at the positions of the joints 2, 3, 4, and the bent state will remain, resulting in the airtightness of the shutter T. In addition, since such a conventional shutter T slides in a suspended state along the hanger rail 9, if the shutter T is closed particularly forcefully, the pull joint stile 7 may come off the door. When the moving inertia force collides with the frame 13, the suspension frame 5 and the suspension joint frame 6 on the opposite side
It is easy to cause damage to the affected part by applying an impact.

Therefore, as a specific example of the present invention, in the embodiment shown in FIG. The connecting frame 6 is connected to the hanging frame 5 with a clearance so that it can be pulled out.
Engagement ribs 62, 62' are provided on the rear edge to protrude in the width direction, while a stop plate 53 is removably provided on at least one side edge of the opening 51 in the suspension frame. 53 and the engaging rib 6 of the joint stile
2 and 62' constitute a joint frame retaining mechanism, and a buffer spring 63 as shown in FIG. , the joint frame 6 slides along the guide plate 52 removably attached to the suspension frame 5, and securely abuts against the stop plate 53 disposed in the suspension frame opening 51. be.

Although the present embodiment is generally constructed as described above, the present invention is not limited to the above embodiment, and appropriate design changes may be made in response to specific requests within the scope of the claims for utility model registration. Needless to say, it is possible to add

[Effects of this invention]

As is clear from the structural description of the above embodiments, according to the present invention, even if there is some error between the shutter and the built-in opening, the joint stile on the side of the hanging side has clearance from the hanging frame. Since only the free space (the long part in Figure 3) can be pulled out,
This error can be absorbed.

In addition, even if the horizontal pull shutter of the present invention is pulled vigorously and causes the pull stile to collide with the door frame, the movement inertia of the shutter is buffered by the action of the buffer spring attached to the front surface of the engaging rib of the coupling stile. Since the reaction impact directly on the suspension frame is alleviated, there is no risk of damage to the suspension frame due to opening and closing of the shutter.

In this way, the horizontal pulling shutter constructed by applying the present invention can solve all the technical difficulties that were conventionally given up as unavoidable in this type of horizontal pulling shutter, and also has improved durability. It far exceeds the level of conventional products in terms of both surface and practicality, and should be said to be of great benefit to the construction industry.
