Description

[Detailed Description of the Invention] The present invention relates to a guide rail wiping device in a shutter such as a heavy-duty shutter that opens and closes an opening.

Generally, this type of shutter opens and closes the opening by moving the shutter curtain up and down while being guided by a guide rail. However, even with such a shutter, as it ages after being installed for a long time, the guide rails may become rusty or collect dust.
When the shutter curtain was moved up and down, the seat plate and slats came into contact with the rusted guide rails and rubbed, causing abnormal and unpleasant noises such as squeaking, which was a problem.

The present invention was devised in order to eliminate these drawbacks in view of the above-mentioned actual situation, and effectively utilizes the up-and-down movement of the shutter curtain to wipe the guide rail while applying an appropriate amount of oil. This makes it possible to automatically prevent rust and clean the guide rails, so that even if the shutter curtain is old, the seat plate or slats will not touch the guide rails when the shutter curtain moves up and down. The purpose of the present invention is to provide a guide rail wiping device for a shutter that can prevent the generation of strange unpleasant noises due to rubbing, and is particularly suitable for wiping a shutter curtain that moves while being guided by a guide rail. The seat plate is provided with a wiping part for wiping the guide rail, and the wiping part is provided with an oil tank having an oil supply mechanism that supplies oil to the wiping part in conjunction with the opening/closing operation of the shutter curtain. It is characterized by the presence of

Next, the present invention will be explained in more detail based on an embodiment shown in the drawings. In the drawing, 1 is a shutter curtain of a heavy shutter, and the shutter curtain 1 has left and right guide rails 2.
The opening is opened and closed by moving up and down while being guided by. Reference numeral 3 denotes a substantially inverted T-shaped seat plate attached to the lowermost slat 1a of the shutter curtain 1, and the left and right sides of the seat plate 3 have bottom plate portions that fit loosely into the guide rail 2. is cut out.

Reference numeral 4 denotes an oil supply mechanism attached to the left and right notches of the seat plate 3, and an oil tank 5 housing the oil supply mechanism 4 is integrally fixed to the indoor side surface of the seat plate 3 with screws or the like. is fixed. In this embodiment, the lid 6 of the oil tank 5 is made of a flexible member such as a soft elastic material, and is set to close the oil tank 5 at all times. 7 is integrally attached. The lower end of the pin body 7 is retractably fitted into the outlet 8 formed in the bottom plate 5a of the oil tank 5, and when the lid body 6 is in the downward movement position closing the oil tank 5 as described above, the pin The body 7 is deeply fitted into the outlet 8 and closes the outlet 8, but when the cover 6 is pushed upward as described later, the pin body 7 is pulled out from the outlet 8. , the oil in the oil tank 5 is supplied to the lower wiping section 9. The wiping section 9 is provided on the front and rear surfaces of the seat plate 3, and is equipped with a wiping body 10 made of an appropriate oil-retentive member such as twine, sponge, or brush. This wiping body 10 is in sliding contact with the inner surface of the guide rail 2, and whenever the shutter curtain 1 moves up and down, the guide rail 2
It is designed to apply oil at the same time as wiping away.

On the other hand, a wedge-shaped protrusion 11 is fixed at an appropriate position on the guide rail 2.
1, when the shutter curtain 1 moves downward, the lid body 6 comes into contact with the protrusion 11, and the lid body 6 is pushed upward for a short time, whereby the shutter curtain As mentioned above, the oil in the oil tank 5 is supplied to the wiping part 9 in an appropriate amount in conjunction with the opening/closing operation of the shutter curtain 1. body 6 is protrusion 1
1, the lid 6 can escape because the protrusion 11 is semicircular.

In the embodiment of the present invention configured as described above, the opening is opened and closed by the up and down movement of the shutter curtain 1, but the guide rail 2 comes into contact with each other each time the shutter curtain 1 moves up and down. In addition to being wiped off by the wiping body 10, oil is also applied. Therefore, even if the guide rail 2 is used for a long period of time, it will not rust or have dust attached to it. Therefore, even if the shutter has become old after a long period of time has passed since installation, it is effectively possible to prevent the seat plate 3 or slats from rubbing against the guide rail 2 and producing strange and unpleasant noises, as in the case of conventional shutters. can do. Moreover, oil is supplied to the wiping body 10 only by the shutter curtain 1.
Every time it moves up and down (usually about once a day),
Since the cover body 6 comes into contact with the protrusion 11 to ensure that the appropriate amount of oil is removed, there is no inconvenience such as the guide rail 2 being contaminated with oil due to too much oil being supplied to the wiping body 10. In addition, the oil will not run out within a single period of time, and will always be maintained at an optimal oil retention state for a long period of time.

In summary, the present invention provides a wiping section for wiping the guide rail on the seat plate of the shutter curtain that moves while being guided by the guide rail, and the wiping section is provided with a wiping section connected to the opening/closing operation of the shutter curtain. Since an oil tank equipped with an oil supply mechanism that supplies oil to the wiping section is provided, the guide rail is wiped by the wiping section and coated with oil each time the shutter curtain is opened or closed. As a result, it is possible to effectively prevent the occurrence of rust and the adhesion of dust. Therefore, even if the shutter is old, it is possible to prevent the guide rail from rubbing against the seat plate or slats, thereby preventing the occurrence of strange and unpleasant noises. Moreover, this wiping section effectively utilizes the opening and closing operations of the shutter curtain to supply oil in appropriate amounts from the oil tank, eliminating the need for a special oil supply mechanism and providing long-term use. It is possible to apply oil stably using the ivy wiping part.
