Description

[Detailed Description of the Invention] The present invention relates to a slat for a grill shutter into which a glass plate or a synthetic resin plate can be fitted.

Conventional grill shutters are assembled into a grill shape using pipes and links made of iron, non-ferrous metals, or stainless steel, and are used for show windows because of their transparency and excellent lighting. It is being said.

The present invention provides a slat for a grill shutter that can provide airtightness and fire protection without losing the characteristics of a conventional grill shutter, and can be assembled and manufactured economically. With the goal.

In order to achieve the above object, the present invention provides discontinuous punching holes in the flat part of the slat body made of a rigid material such as iron plate, steel plate, stainless steel plate, or non-ferrous metal plate, so that the four circumferences of each punching hole are forming an edge frame integral with the slat body, and providing a pair of upper and lower panel clamping grooves facing each other across the punching hole on the rear surface of the slat main body, the panel clamping grooves having a size that blocks the punching hole; A single transparent or translucent panel made of glass synthetic resin or a fireproof material is fitted with a single or multiple glass synthetic resin or fireproof material panels formed to have approximately the same length as the slat width, or a plurality of transparent or translucent panels made of glass synthetic resin or fireproof material are fitted in the slat width direction. is characterized in that an end plate is arranged, and mounting legs protruding from one side of the end plate are inserted into the panel holding grooves and fixed to both ends of the slat, and the panel and the mounting legs are abutted and fixed. be.

In the present invention, discontinuous punch holes are provided in the slat main body, and an edge frame is formed around the four circumferences of each punch hole, which is integrated with the main body. Therefore, the number of parts can be reduced without increasing the number of parts, and without complicating the assembly process. A grill shutter slat with sufficient strength can be obtained. Mounting legs were provided protruding from one side of the end plates arranged on both sides of the slats, and the mounting legs were inserted into the panel holding grooves and fixed to both ends of the slats, and the mounting legs were installed so as to close the holes. Since the panels are fixed against each other, movement of the panels is prevented, and a high level of airtightness and fireproofness can be maintained without impairing the transparency of the slats.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In Figs. 1 to 4, reference numeral 1 denotes a flat plate-shaped slat body, and a male linking part 3 having a shaft rod 2 with a circular cross section and formed to protrude along the longitudinal direction of the slat body is integrally attached to the upper end of the slat body. On the other hand, at the lower end of the slat body 1, there is a female-shaped engagement piece 4 having a C-shaped cross section and a shaft hole in which the shaft rod 2 can be fitted, along the longitudinal direction of the slat body. The linking portions 5 are integrally connected. Further, discontinuous punch holes 6 are provided in the central plane part of the slat body 1 at regular intervals. Around the four circumferences of these punch holes 6, edge frames 6a are formed integrally with the slat main body 1. Furthermore, on the rear side of the slat main body 1, a pair of glass clamping pieces 7, 7 are provided facing each other at positions above and below the punching hole 6.
These clamping pieces 7, 7 and the slat main body 1 form a pair of upper and lower glass clamping grooves 8, 8 as shown in the figure. As shown in FIGS. 1 and 4, between the clamping grooves 8 and 8, there is a single plate having a size to close the punch hole 6 and having a length approximately equal to the width of the slat.
Alternatively, a plurality of transparent or translucent glasses 9 made of glass, synthetic resin, or fireproof material are fitted in the slats in a butt-width direction. Note that end plates 10 are attached to both sides of the slat body 1. This end plate 10
As shown in FIGS. 2 and 3, mounting legs 11 are provided on one side of the panel so as to protrude from the end plates so as to be able to be inserted into the panel holding grooves 8. Insert this mounting leg between the clamping grooves 8 and 8, and then
1 and the glass plate or synthetic resin plate 9 to prevent the glass plate or synthetic resin plate 9 from slipping out, and the end plate itself is riveted to the edge frame 6a of the slat body 1. 1
2 etc. are used to secure it.

A grille shutter formed using the shutter slat having the above structure is as shown in FIGS. 3 and 4. In order to connect a plurality of slat bodies 1 prepared as shown in the figure so as to be rotatable in the vertical direction, the shaft rod 2 of one slat is inserted into the engagement piece 4 of another slat to be connected to it. and are joined together in a linked manner to form a grille shutter.

Incidentally, in the illustrated embodiment, the male connecting portion is provided at the upper end of the slat body, and the female connecting portion is provided at the lower end, but the relationship between the two may be reversed. In addition,
The connecting portion of the slat may be of the so-called interlocking type. Further, when the glass plate or synthetic resin plate fitted into the clamping groove on the rear surface of the slat is made of a transparent fireproof member, the shutter itself can be provided with fireproof properties.

The slat main body in the present invention may be made of any material such as iron plate, steel plate, or stainless steel plate, but it is preferable to make it from aluminum material, so that the weight of the slat body as a whole can be reduced.

As mentioned above, in the present invention, discontinuous punch holes are provided in the plane part of the slat body made of a rigid material, and a frame is formed integrally with the body around the four circumferences of each punch hole, so it is different from the conventional example. Unlike the case where the slat body is divided into upper and lower parts to provide a window, and the upper and lower slat members are integrally connected with a joint plate,
There is an effect that a slat for a grill shutter having sufficient slat strength can be obtained without requiring special joint members or strength members.

In addition, end plates are arranged on both sides of the slat, and mounting legs protruding from one side of the end plate are inserted into panel holding grooves and fixed to both ends of the slat, and the panel is attached so as to close the mounting legs and the holes. Since the panels are fixed against each other, they will not move or fall off accidentally, and the transparency of the slats will not be impaired.
It is possible to maintain a high level of airtightness and fire resistance.

In addition, if the panel needs to be replaced due to damage, the panel can be easily replaced without disengaging the slats by removing the mounting legs provided on the end plate at the required positions from their insertion grooves. There are benefits to be gained.
