Description

[Detailed description of the invention] The present invention relates to a seat plate having an engagement receiving part for a hook rod for opening and closing a shutter, and more specifically, the hook rod for opening and closing a shutter is inserted into the seat plate of a lightweight shutter that is opened and closed by manual operation. The present invention relates to a seat plate having an engagement receiving portion for a shutter opening/closing hook rod, which is formed by integrally projecting upwardly a substantially circular bulge portion having a portion and an engagement receiving seat.

Conventionally, lightweight shutters that can be opened and closed manually have been provided with handles for opening and closing on the slats located at appropriate heights among the slats that make up the shutter curtain, and on the lower end of the lowest slat. A long groove-shaped engagement hole that engages with a hook rod for opening and closing the shutter is bored in the seat plate attached to the shutter. The shutter is opened and closed using a stick.

However, when drilling the engagement hole for engaging the hook rod, secondary processing is performed on the seat plate made of decorative steel plate, which deteriorates the rust prevention function of the seat plate and makes it difficult to drill. The seat plate is prone to rust from the engaged holes,
In addition, since the hook rod is engaged with the engagement hole each time the shutter is opened or closed, the engagement impact with the hook rod may rub against the circumferential surface of the engagement hole, damaging the decorative film and reducing the durability of the seat plate. We do not allow it to have a negative impact on
When the shutter is in the open state, the seat plate is supported by contacting the lintel above the opening, so rusted or damaged parts of the seat plate are exposed for easy viewing from below. The aesthetic appearance of the board is damaged, and especially in the case of shutters installed in stores, etc., it becomes incongruous with the beauty of the surrounding product displays, etc., and even though the shutter components are made of decorative steel sheets, There were drawbacks that significantly reduced the commercial value of the product.

The present invention has been devised based on a completely new concept in view of the above-mentioned circumstances, and its purpose is to improve the seat of the shutter, especially in shutters that are opened and closed by manual operation. A circular bulge consisting of a short diameter part and a long diameter part is integrally projected upward at a desired position in the central region in the longitudinal direction of the plate, and a shutter opening/closing hook is provided in the inner hollow part of the bulge part. By forming an insertion portion for the rod and reducing the bulge shape of the bulge portion from the upper side to the lower side to form an engagement receiving seat for the hook rod on the lower inner circumferential surface of the insertion portion, When forming the engagement receiving part of the opening/closing hook on the seat plate, there is no need for drilling and there are no parts that are prone to rust, thereby preventing the deterioration of the rust prevention function of the seat plate as much as possible. At the same time, the damaged part of the insertion part that occurs over time due to being rubbed by the hook rod when opening and closing the shutter is not visible from the outside, and the aesthetic appearance of the seat plate is spoiled when the shutter installed in a store etc. is left open. The hook rod for opening and closing the shutter can be harmonized with the beauty of the surrounding product displays without any problems, and in addition, the shape of the hook rod that engages with the engagement receiving part can be simplified to facilitate processing. It is an object of the present invention to provide a seat plate having an engagement receiving part.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, 1 is a shutter curtain, and the shutter curtain 1 has a plurality of slats 1.
Interlock a, 1a... respectively 1b, 1b
They are rotatably connected to each other via. 2 is a guide rail, and the guide rail 2 is erected on both the left and right sides of an opening such as an entrance of a building,
A shutter case 3 is connected to its upper end. The uppermost slat of the shutter curtain 1 is connected via a suitable hanging plate (not shown) to a winding drum 3b which is rotatably mounted on a shaft between the left and right brackets 3a of the shutter case 3. A seat plate 4 is attached to the lower end of the lowest slat. A short diameter portion 5a and a long diameter portion 5b are located at desired positions in the longitudinal center region of the seat plate 4.
A substantially inertial circular bulge 5 is integrally formed upward by press working, and an insertion portion 7 for a shutter opening/closing hook rod 6 is formed in the inner cavity of the bulge 5. There is. Further, the bulging shape of the bulging portion 5 is smaller on the lower side than on the upper side, and an engagement receiving seat 8 for the hook rod 6 is formed on the inner circumferential surface of the lower side of the insertion portion 7. Then, the engagement receiving portion 9 is formed by the bulging portion 5, the insertion portion 7, and the engagement receiving seat 8.
is configured. 10 is shutter curtain 1
Reference numeral 11 is a lintel for opening and closing, provided on the slat 1a located at an appropriate height among the slats 1a, 1a.

The shape of the engaging portion 6a of the hook rod 6 inserted into the insertion portion 7 is an extremely simple shape that is bulged in the shape of an inertia circle that is approximately the same shape as the bulged portion 5. 6b is aligned with the long diameter portion 5b of the bulging portion 5 and then inserted into the insertion portion 7 and then rotated.
The long diameter portion 6b is adapted to engage with the engagement seat 8.

Next, the operation of the present invention constructed as described above will be explained. To open the shutter, first raise the shutter curtain 1 along the guide rail 2 to an appropriate height using the handle part 10, and then press the long diameter part of the engaging part 6a of the hook rod 6. 6b is aligned with the long diameter portion 5b of the bulging portion 5, and is inserted into the insertion portion 7, and then pushed upward to bring the surface of the seat plate 4 into contact with the lintel portion 11.

When closing the shutter, first insert the hook rod 6 into the insertion portion 7 with the long diameter portion 6b of the engaging portion 6a aligned with the long diameter portion 5b of the bulging portion 5, and then rotate the hook rod 6. When moved, the long diameter portion 6
b engages with the engagement seat 8 formed on the lower inner circumferential surface of the insertion portion 7, so if it is pulled downward,
The shutter curtain 1 descends along the guide rail 2. Therefore, after descending to an appropriate height, the shutter curtain 1 may be lowered by rotating the hook rod 6, holding the seat plate 4 and the handle portion 10 by hand, and lowering the shutter curtain 1 until the seat plate 4 lands on the floor.

By the way, during the above series of manual operations to open and close the shutter, the decorative film applied to the inner circumferential surface of the insertion portion 7 is rubbed by the engaging portion 6a of the hook rod 6 and is damaged over time. Since the shape of the bulging portion 5 of 9 is smaller on the lower side than on the upper side, the damaged portion is not visible from the outside even when the shutter is in the open state, which spoils the aesthetic appearance of the seat plate 4. Nothing happened at all. In addition, when opening and closing the shutter, the parts of the seat plate 4 other than the insertion part 7 are not allowed to come into contact with the hook rod 6 at all, and there are no parts that are likely to rust, so the seat plate 4 has a rust-preventing function. can maintain its durability for a long time. Moreover, the shape of the engaging portion 6a of the hook rod 6 can be simplified to correspond to the shape of the engaging receiving portion 9, and the shutter can be opened and closed smoothly, and the hook rod 6 can be easily processed. Together with this, material costs can be significantly reduced.

In summary, the present invention provides a shutter that is opened and closed by manual operation, at a desired position in the longitudinal center area of the seat plate of the shutter.
A substantially circular-shaped bulge consisting of a short diameter part and a long diameter part is integrally projected upward, and an insertion part for a shutter opening/closing hook rod is formed in the inner hollow part of the bulge part. Since the bulging shape of the protrusion is made smaller on the lower side than on the upper side, and an engagement receptacle for the hook rod is formed on the inner peripheral surface of the lower side of the insertion portion, the engagement receptacle for the opening/closing hook rod is formed on the seat plate. In forming the seat plate, there is no need for drilling and there are no parts that are prone to rust, and the durability based on the rust prevention function of the seat plate can be maintained for a long time.
Damaged parts of the insertion part that occur over time due to being rubbed by the hook rod when opening and closing the shutter are not visible from the outside, spoiling the aesthetic appearance of the seat plate when a shutter installed in a store etc. is left open. Not only can it be harmonized with the aesthetic beauty of surrounding product displays, but also the shape of the hook bar can be simplified to facilitate processing, which is an extremely useful practical effect.
