Description

  The present invention relates to a roll curtain type bulletin board that can be wound up so that a posted object cannot be seen when it is not needed like a roll curtain.

As what posts a poster or the like, there is a so-called cork board. This cork board is used to attach a post with a thumbtack, an adhesive tape, an adhesive or the like.
In addition, there are types that can use magnets, and some types that can use thumbtacks and magnets as disclosed in JP-A-2005-274660.

JP-A-2005-274660

In the bulletin board, when it is no longer necessary to post, it is necessary to remove the bulletin board or to clear the bulletin board itself. In the case of a posting that needs to be posted intermittently rather than continuously, it is necessary to repeat cleaning and posting again, which is very troublesome.
In addition, a special item such as a thumbtack is required for posting the posting.

  The present invention was devised in view of the above circumstances, and in the case of a posting that requires posting intermittently, it is not necessary to repeat cleaning and reposting, and for the posting, a dedicated item such as a thumbtack. The purpose of the present invention is to provide a roll curtain type bulletin board that does not require the above.

  A roll curtain type bulletin board according to the present invention includes a winding roller and a posting sheet connected to a winding shaft of the winding roller, and the posting sheet is wound around the winding roller. A removable adhesive material is applied to the inner surface.

  The posting sheet has a plurality of sheet materials laminated in a peelable manner, and the releasable adhesive material is applied only to the inner surface when the sheet material is wound around the take-up roller.

  The removable adhesive material for the posting sheet is applied in a spot shape or a zebra shape.

  The surface of the posting sheet on which the removable adhesive material is not applied has resistance to the removable adhesive material.

  The roll curtain type bulletin board according to the present invention comprises a take-up roller and a notice sheet connected to the take-up shaft of the take-up roller, and the notice sheet is taken up by the take-up roller. Re-peelable adhesive material is applied to the inner surface of the paper, so in the case of postings that need to be posted intermittently, it can be easily removed simply by winding up the take-up roller. By simply pulling out, it is possible to easily perform posting again. Moreover, no special items such as thumbtacks are required for posting.

  FIG. 1 is a schematic front view of a roll curtain type bulletin board according to an embodiment of the present invention, FIG. 2 is a schematic side view of the roll curtain type bulletin board according to the embodiment of the present invention, and FIG. FIG. 4 is a schematic enlarged cross-sectional view of a sheet for posting on a roll curtain type bulletin board according to the embodiment, and FIG. 4 is a schematic enlarged cross-sectional view of a sheet for posting on a roll curtain type bulletin board according to another embodiment of the present invention.

  A roll curtain type bulletin board 100 according to an embodiment of the present invention includes a winding roller 110 and a posting sheet 120 connected to a winding shaft 111 of the winding roller 110, and the posting sheet 120. The removable adhesive material 122 is applied to the inner surface (hereinafter referred to as “inner surface 121 </ b> A”) when wound on the winding roller 110.

  The take-up roller 110 is the same as that used in a normal roll curtain, and includes a take-up shaft 111, a support 112 that the take-up shaft 111 rotatably supports, and the take-up shaft. An elastic body (not shown) that biases 111 in the winding direction, and a stopper that prevents the elastic body from being biased in order to maintain the state in which the posting sheet 120 connected to the winding shaft 111 is pulled out. (Not shown).

  As shown in FIG. 1, the support 112 has a mounting portion 112A and a support portion 112B extending in a substantially orthogonal direction from both ends of the mounting portion 112A. It is formed into a shape. The mounting portion 112A has a plurality of screw holes (not shown) through which screws (not shown) for attaching the roll curtain type bulletin board 100 to the ceiling surface T or the like pass. The support portion 112B supports the take-up shaft 111 in a rotatable manner, and a shaft portion (not shown) that supports the take-up shaft 111 protrudes inward.

  The support 112 may be attached to the ceiling surface T or the like by other appropriate means such as an adhesive or a double-sided adhesive tape as well as screws, or these may be used in combination. .

In general, the elastic body and the stopper are set between the support tool 112 and the take-up shaft 111, and the posting sheet 120 is pulled out against the urging force of the elastic body. When the posting sheet 120 is being pulled out, the stopper prevents the urging force of the elastic body. Therefore, the posting sheet 120 is pulled out smoothly.
When the pulling out of the posting sheet 120 is stopped, the stopper maintains the state in which the biasing force of the elastic body is blocked, so that the posting sheet 120 is maintained in the pulled out state.
When the posting sheet 120 is slightly pulled out from this state, the blocking of the urging force of the elastic body by the stopper is released, and the posting sheet 120 is automatically wound around the winding shaft 111 by the rotation of the winding shaft 111 by the elastic body. Taken.

  The posting sheet 120 is, for example, a rectangular sheet made of synthetic resin, and one end is attached to the winding shaft 111. Further, a shaft-like lower end shaft 123 is attached to the other end of the posting sheet 120. The lower end shaft 123 is provided so as not to become a weight of the drawn sheet 120 for posting. A pulling string 124 for pulling out the posting sheet 120 is attached to the lower end shaft 123.

  In addition, it is desirable that the outer surface 121 </ b> B of the posting sheet 120, that is, the surface opposite to the inner surface 121 </ b> A to which the removable adhesive material 122 is applied has resistance to the removable adhesive material 122. Even if the outer side surface 121B does not have resistance to the re-peelable adhesive material 122, that is, it is firmly attached to the re-tacky pressure-sensitive adhesive material 122 and cannot be re-peeled or re-peelable, If the material 122 loses the adhesiveness, it is difficult to post the posting again on the wound posting sheet 120.

  As a method of imparting resistance to the releasable adhesive material 122, it is conceivable to coat the outer surface of the posting sheet 120 with a material having resistance, or to configure the posting sheet 120 itself from a material having resistance.

On the inner side surface 121A of the posting sheet 120, the removable adhesive material 122 is applied in a spot shape. The re-peelable adhesive material 122 adheres when a post such as a poster is pressed, but peels easily when peeled off and does not adhere to the post side. For example, a typical example is an acrylic adhesive.
The reason why the re-peelable adhesive material 122 is applied in a spot shape to the inner side surface 121A of the posting sheet 120 is to make it possible to easily peel off the posting.

The roll curtain type bulletin board 100 configured as described above is used as follows.
First, a poster or other post is pasted on the post-posting sheet 120. Although posting is performed in this state, when the posting is interrupted, the posting can be easily hidden by winding the posting sheet 120 on the winding shaft 111.

  In addition, when the bulletin sheet 120 is wound around the winding shaft 111 when the bulletin board is first attached to the bulletin sheet 120, the bulletin sheet 120 is wound up, so that the bulletin sheet 120 is wound up. Since the pressure is applied evenly, the posting can be more reliably attached to the posting sheet 120.

  Even if the posting material is peeled off from the posting sheet 120, the re-peelable adhesive material 122 of the posting sheet 120 does not lose its adhesiveness, so that many postings can be posted many times.

  By using a light-shielding material for the posting sheet 120, it can also be used as a general roll curtain.

  In the roll curtain type bulletin board 100 described above, the number of the posting sheets 120 is one. However, as will be described below, a plurality of sheets (three sheets in FIG. 4) 125 are laminated so as to be peeled and wound. It is also possible that the removable adhesive material 122 is applied only to the inner side surface 121A which is the inner side when wound on the take-up roller 111.

  As shown in FIG. 4, the releasable adhesive material 122 is applied only to the inner side surface 121A of a plurality of sheet materials 125 of the same shape and the same size, and is laminated so that the inner side surfaces 121A do not overlap each other. If the stickiness of the posted material is lost due to long-term use, the sheet material 125 that has lost the adhesive property is peeled off to expose a new sheet material 125, and the posted material is displayed on the new sheet material 125. It becomes possible to paste.

  In the above-described embodiment, the removable adhesive material 122 is applied in a spot shape. However, the present invention is not limited to this, and it may be applied on the entire surface or in a zebra shape. Needless to say.
