Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a roller chain structure of a panel shutter, and more particularly, according to a change in weight of each panel connecting position of a shutter curtain that moves up and down along a guide rail. The present invention relates to a roller chain structure of a panel shutter that can appropriately set the suspension strength of a roller chain that connects the panels.

[Prior Art] Conventionally, in a panel shutter in which panels are vertically connected to form a shutter curtain, and the shutter curtain is opened and closed in an opening of a building, a safe lifting operation of the shutter curtain is ensured. Therefore, a roller chain having a strength against the total weight of the shutter curtain is connected to both ends of the shutter curtain.

However, since this one uses a single roller chain from the suspension base end of the roller chain to the suspension tip end that connects the panel at the bottom end of the shutter curtain, the opening for mounting the panel shutter is In order to cope with the increase in the total weight of the shutter curtain due to the difference in the opening height of the parts, the roller chain to be used also needs to be changed to a chain with a large chain pitch, which inevitably results in the above. The guide sprocket that meshes with the chain must also have a large diameter so as to match the chain pitch, so the shutter storage case that houses the guide sprocket becomes large, and the guide sprocket below The panels to be joined do not require high chain strength, but a single roller chain In addition to having the disadvantage that the weight of the shutter curtain is increased as a result, unnecessary chain strength is given, and when using a chain with a large chain pitch, It is said that the link plates into which the support shafts provided at both ends of the panel are inserted must also be large, and it becomes necessary to prepare several types of chains and link plates, which complicates the panel shutter assembly process. There was also a fear.

[Problems to be Solved by the Present Invention] In view of the above-mentioned circumstances, the present invention was devised to eliminate the conventional drawbacks, and the purpose thereof is to provide a roller chain for connecting shutter curtains. To
The shutter curtains are configured to be installed in series according to the total weight of the panels to be connected, and even if the opening heights are different, the same roller chain is used to suspend the shutter curtain with appropriate chain strength. It is intended to provide a roller chain structure of a panel shutter that can be used.

[Means for Solving the Problems] In order to solve the problems, the technical means adopted by the present invention are:
A roller chain is rotatably pivoted to the left and right support shafts protruding from each panel, and a plurality of panels are connected in series to form a shutter curtain, and the roller chain is formed by the forward and reverse rotational movements of the induction sprocket. In the panel shutter configured so that the respective panels are forcibly fed and can be transferred to the vertical guide rail provided in the opening and the horizontal storage rail provided above the opening, the roller chain comprises: A main chain that suspends all the panels of the shutter curtain and a sub-chain that has a shorter suspension length than the main chain are juxtaposed in the left-right direction, and the weight of the panel gradually increases from the bottom to the top of the shutter curtain. In order to cope with the change, if the sub-chain and the main chain are pivotally connected to the spindles of the panels connected between the middle and the upper part of the opening, respectively. In addition, an induction sprocket that suspends the main chain and an induction sprocket of the same shape that suspends the sub chain are coaxially mounted, and the two chains are configured to rotate forward and backward in synchronization with each other. It is what
