Description

[Detailed description of the invention] [Field of industrial application] The present invention is an improvement of the suspension type joint joint structure for horizontal pulling shutters. This relates to a side-pull shutter that is not only convenient but also easy to open and close.

[Conventional technology and technical issues to be solved]

In recent years, foldable horizontal shutters as shown in Figure 1 have come into widespread use in place of shutters, but such shutters consist of a vertical frame 1 that serves as the hanging base and a vertical frame that serves as the doorstop. Since it is necessary to airtightly close the wide space between the doorways in which the shutters 2 are disposed and to withstand large wind pressure, the overall weight of the shutter is considerable. For this reason, the suspension wheel structure portion attached to the upper end of the joint joint 3 located at the numeral number from the vertical frame 1 on the suspension side is required to be highly durable and have a large allowable hanging load.

In addition, when this type of horizontal shutter is expanded and contracted to open and close, the upper and lower ends of the joint joints 4, 4, located at even numbers from the vertical frame 1 of the hanging base, are connected to the upper and lower rails 5, 6. It is necessary to get away from it.
In this case, since the upper end of one side edge of each shutter piece 7, 7... will be folded, bent and stretched in a state that it is detached, it will inevitably happen that when this part slides on the upper and lower rails 5, 6, it will move laterally. Shaking is likely to occur,
This may cause trouble opening/closing the shutter, or may cause excessive vibration or
External forces are applied to the hanging wheels attached to the odd-numbered joints, causing damage there.

This invention was developed in an attempt to improve the above-mentioned drawbacks of conventional horizontal pull-up shutters. The technical objective is to provide a practical joint structure that is rich in smooth straight-line running performance without causing any friction.

[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, in the present invention, the shutter bodies 7, 7, which are formed by foldably connecting the shutter pieces 7, 7, etc. in a continuous manner in the horizontal direction, are connected by the vertical frames 1, 2 and the upper and lower rails 5, 6. Based on the technical premise of a conventionally well-known hanging type horizontal pulling shutter built in an openable and closable manner in an enclosed opening, the connecting portion 3 located at the numeral number in the shutter body 7, 7... (a) The main body 11 has hinge shafts 13, 13 which are vertically elongated rods, and at least the upper and lower ends of the main body 11 are hollow, and the shutter pieces 7 are foldably and slidably connected to both sides of the main body 11.
(b) It is a part having a cross shape as a whole, and has a head part 21a that can protrude upwards, and hanger rollers 22, 22 are arranged to sandwich the head part in the front and back. The hanging portion 21b, which is slidably engaged with the rail grooves 57, 57 of the upper rail 5 and can protrude downward, is connected to the main body 1 of the joint bar 10.
A shoulder portion 21 is inserted into the upper end of 1 and fixed with a screw 23, and further protrudes in the left and right width direction.
c, 21c are means called a suspension wheel 20 fixed to the upper ends of the hinge shafts 13, 13 of the joint joint bar 10; (c) an insertion part whose overall shape is an inverted T-shape and which can protrude upward; A screw 33 is inserted into the lower end of the main body portion 11 of the joint bar 10.
The sliding part 31, which can be fixed in a block shape at the bottom and can bulge out in the form of a block, incorporates a mechanical means called a slider 30 that loosely fits into the groove of the lower rail 6 and can slide. The gist lies in the fact that it is constructed as a suspension type joint structure for the shutter.

〔Example〕

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

As shown in FIG. 2, the joint structure of this embodiment includes a joint bar 10, a suspension wheel 20, and a slider 30 arranged at odd-numbered connection parts of the shutter bodies 7, 7... This is the main point.

First, the above-mentioned joint bar 10 is a vertically long hollow deformed aluminum rod formed by extrusion processing of aluminum.The main body part 11 is hollow, and reinforcing ribs 12, 12 are provided protruding from the front and back. On the other hand, on both sides, hinge shafts 13, 13 having circular outer peripheries that can be smoothly fitted around the shaft are formed on arcuate bearings 7a formed on the side edges of the shutter piece 7, as shown in FIG. .

Next, the overall shape of the suspension wheel 20 is a cross, and a head 21a that can protrude upward is provided with hanger rollers 21 that sandwich the head in front and back.
2, 22 are arranged to form the rail groove 57 of the upper rail 5,
The hanging part 21b that is slidably engaged with the joint bar 57 and can protrude downward is the joint bar 1.
The shoulder parts 21c, 21c, which are inserted into the upper end of the main body part 11 of 0 and fixed with screws 23, and which can further protrude in the left-right width direction, are fixed to the upper ends of the hinge shafts 13, 13 of the joint joint bar 10. Preferably, it is integral with the coupling bar 10 mentioned above.

Next, the slider 30 has an inverted T shape as a whole.
The insertion portion 32 has a letter shape and can protrude upward.
is inserted into the lower end of the main body portion 11 of the joint bar 10 and fixed with a screw 33, and
The sliding portion 31 that can bulge out in the shape of a block at the bottom is slidably fitted into the groove of the lower rail 6 in a loose fit state, and screws 35 are attached to the lower ends of the hinge shafts 13, 13 of the joint bar from the bottom surface of the block. 3
5, it is firmly fixed.

Therefore, the above-mentioned joint structure of this embodiment is as follows:
It is used as an odd-numbered joint 3 located from the vertical frame 1 that serves as the hanging source, but in order to make it convenient for hanging, the upper rail 5, that is, the hanger rail, is attached as shown in Figure 4. It is divided into a receiving side member 51 that is fixed to the hanger anchor 50 on the lintel side, and an insertion side member 52 that is attached and fixed after hanging the shutter. The strip 54 is inserted and screwed 5 at the upper hollow reinforcing structure 55 position of the receiving member 51.
It is preferable to set it to 6. It should be noted that a ceiling plate 59 is located at both side engaging portions 58, 58 below the rail grooves 57, 57.

On the other hand, the slider 3 at the lower end of the joint 3
0 is inserted into the lower rail 6 which is prevented from narrowing by a chevron-shaped lower anchor 61.

Although the "joint joint structure" of this embodiment is manufactured as described above, the present invention is by no means limited to the above-mentioned embodiment, and within the scope of the "Utility Model Registration Claims" It goes without saying that appropriate design changes can be made depending on specific needs.

[Effects of this invention]

As explained above with the examples, the folding type horizontal pull shutter manufactured by applying the present invention is
It can be assembled quickly by simply inserting the suspension wheel and slider into the upper and lower ends of the joint bar and securing them with screws, which not only reduces production costs but also reduces the shoulder that protrudes to the side. is secured to the hinge shaft of the joint bar with screws or other means, and the suspension wheel inserted into the top end of the joint bar is secured with screws from the side to ensure a strict prevention of removal, increasing the allowable hanging load. It becomes larger and its durability improves dramatically.

Furthermore, the horizontal pull shutter to which this invention is applied,
The block-shaped sliding part of the slider slides straight forward while being guided and regulated by the groove wall of the lower rail, so there is no rotation or sideways movement about the central axis of the joint joint as a fulcrum when opening and closing the shutter, unlike in the conventional case. This not only makes opening and closing the shutter easier, but also significantly improves the durability of the suspension wheel.
