Description

The present invention provides a POS for locations that require work using high ceilings, stepladders, ladders, etc.
The present invention relates to an apparatus for raising and lowering a banner when performing operations such as easy installation and replacement of banners such as advertisements and posters.

  The article lifting device has a plurality of winding shafts fixed to a motor at a high place such as a ceiling, and the plurality of shafts are rotated and wound uniformly so as to correlate with each other and lifted and lowered by remote control. The mechanism is conventionally known from JP 2008-524092 A (Patent Document 1) or the like. In addition to Patent Document 1, this lifting device can freely lift and lower articles as disclosed in JP-A-7-223800 (Patent Document 2), JP-A-2002-80191 (Patent Document 3), and the like. It is possible.

For example, the structure of the article device of Patent Document 1 includes a tube, a motor connected to the tube, and a motor for rotating the tube, a plurality of cables spaced apart from each other and fixed to the tube and the article, To index the plurality of tubes along the tube when the plurality of cables are wound on the tube in order to uniformly wrap the plurality of cables around the tube. A cable indexer coupled in synchronism with the tube. With this structure, the article fixed to the tube is moved up and down.

In addition, the lifting devices of Patent Documents 2 and 3 are fixed lifting devices, and are configured to lift and lift heavy objects, not lightweight objects such as POS advertisements and posters.

In this way, the lifting device with a configuration specializing in lightweight items such as POS advertisements, posters, etc.
Since it was a replacement work at a high place such as the ceiling, there was a risk of a fall accident, etc., so we asked a specialist to replace it. In addition, there is a problem that it is difficult to install because it is very complicated and expensive.

JP 2008-524092 A JP-A-7-223800 JP 2002-80191 A

For example, the raising / lowering structure of the hanging curtain disclosed in Patent Document 1 requires a large space for the hanging curtain to move left and right while moving up and down for index feeding when winding a plurality of tubes.
Further, since the motor is fixed to the take-up shaft, the motor is rotated, so that it must be operated remotely. Therefore, the structure is very complicated, the price is expensive, and the installation is difficult.

Moreover, in the raising / lowering apparatus of patent document 2, it is a mechanism aiming at raising / lowering the stand which mounts articles | goods, and also in patent document 3, it is a mechanism which raises / lowers articles | goods, and is used by fixing an apparatus, After changing the banner, it is necessary to leave nothing.

Therefore, the technical problem to be solved by the present invention is to solve the above-mentioned problems, facilitate the raising and lowering of the banner, and without having to perform replacement work at a high place without requesting a replacement specialist. Even the store clerk will be able to avoid the danger and replace it. Another object of the present invention is to provide a banner lifting device as a system that can be made very inexpensive.

    In order to solve the above technical problem, the present invention provides a hanging curtain lifting device having the following configuration.

A shaft for winding the tape between saliva, a rotating piece fixed to the side end,
A hanging curtain elevating device is provided.

According to the second aspect of the present invention, it further has a planetary reduction motor at the tip of the telescopic pipe,
At its tip, it has a transmission piece that rotates the rotary piece,
There is provided a first aspect of a banner raising / lowering device that rotates a rotating shaft by pushing a motor unit into a rotary piece.

According to the third aspect of the present invention, a motor unit is provided at the tip of the telescopic pipe,
A spiral electric wire that can extend and retract from the motor is placed in the pipe,
Provided is a first embodiment or a second embodiment of a banner lifting device, which is connected to an operation box at hand of an operator.

  According to the fourth aspect of the present invention, the operation box is installed so as to sandwich the pipe, the electric wire in the pipe is wired to the operation changeover switch, and the banner is moved up and down by the power of the battery, the storage battery or the like. A banner lifting device according to any one of the first to third aspects is provided.

According to the present invention, the hanging curtain can be lifted and lowered straight by providing a hook in accordance with the width of the tape so that a thin tape that can be wound does not sway on the rotating shaft around which the tape, ribbon, or the like is wound.

According to the first aspect of the present invention, ridges are provided at equal intervals around the rotation shaft, and the bearings are inserted from both sides with the bearings inserted from both sides in a state in which the vicinity of the central portion between the ridges and the ridge is cut. By fixing to, it is possible to cope with changes in the width of the hanging curtain, for example, 300 mm, 600 mm, 900 mm, etc., and the hanging curtain can be installed efficiently.

According to the second aspect of the present invention, when the motor unit having the transmission piece fixed to the planetary reduction motor is pushed into the rotating piece, the inner diameter of the transmission piece is pushed in, so that the rotating shaft stopper is moved inward by the spring effect and rotated. Simultaneously with the release of the stop, the switch can be rotated to the right, stopped, or counterclockwise, and the banner can be raised or lowered.
When the motor unit is removed, the rotating shaft stopper returns to the outside due to the spring effect, hits the bearing detent, and prevents the trailing curtain from dropping due to its own weight.
With this configuration, it is possible to work safely and easily even by a store clerk other than the dealer, for example, by simply inserting and removing the transmission piece.

According to the third aspect of the present invention, the motor unit is attached to the tip of the expansion / contraction pipe, and the fastening fixture is provided at the joint of the expansion / contraction pipe, so that the height adjustment and storage can be performed efficiently.

According to the fourth embodiment of the present invention, by sandwiching and fixing the pipe in the bottom container and the lid container,
It becomes a very compact operation box. Further, the operation of raising, lowering, and stopping the banner can be easily performed at the hand of the operator who operates.
