Description

  The present invention is a device for extending a curtain by attaching both ends of the curtain to two shafts installed at a required interval, and is installed especially for the purpose of advertisement, advertisement, etc. in a store or the like The present invention relates to a double-shaft rotary Makuhari apparatus suitable for the above.

  For example, at convenience store stores, a banner-type seat is installed on the ceiling of the eaves, etc., to inform users that they are starting to handle new products and that campaigns are in progress, and to increase purchasing motivation. Has been done. There are many outdoor advertising means, but they are dynamic and sometimes give a messy impression, whereas banner-type seats are static and smart and windy. It has the advantage of being easy to see because it does not shake.

  However, in order to install a banner-type seat, it is necessary to install a frame on the ceiling in advance, which incurs equipment costs, and the seat is attached to the frame with screws, so a platform such as a stepladder is used. It is necessary to work while moving several times. In addition, the outdoor frame is likely to get dirty, such as dust, and it has to be regularly cleaned and time-consuming.

  On the other hand, Japanese Patent Application Laid-Open No. 11-175005 has a mounting means composed of a fixed bracket and a rotary bracket as a display device for advertising and promoting goods at a store, and the fixed bracket has one end of a seat curtain. There is a mounting member for mounting, and the mounting member is provided with a hook at the upper and lower positions to make it easier to mount the seat curtain. However, in the present invention, since one end of the seat curtain is inserted and attached to the fixed bracket, it is necessary to form bag-like attachment portions at both ends of the seat curtain, which requires a sewing operation, which increases costs. In addition, since the length of the sheet curtain is constant, only one advertising advertisement can be displayed. To change the display, the sheet curtain must be exchanged.

JP-A-11-175005

  The present invention has been made paying attention to the above points, and the problem is that it is not necessary to form attachment portions at both ends of the banner type curtain by sewing work or the like, and the curtain can be smoothly stretched. It is to provide a shaft rotation type Makuhari apparatus. Another object of the present invention is to make it possible to extend an arbitrary display unit by moving the curtain in the length direction in a state where the two rotation shafts are stretched.

In order to solve the above problems, the present invention relates to an apparatus for extending a curtain having two shafts installed at a required interval and attaching both ends of the curtain to the shafts.
The two shafts are both rotary shafts, and both rotary shafts can be selectively rotated in the forward and reverse directions by a ratchet mechanism that can switch the rotation direction, and both ends of the curtain are wound around both rotary shafts. In addition, a means is provided in which the curtain is stretched by rotating in the winding direction, and the display provided on the curtain is expanded.

  The apparatus of the present invention is common to the above-described invention in that the curtain is stretched using two shafts. However, both of the two shafts are used as rotating shafts, and the curtain is tensioned by the rotation. It is characterized by providing. Therefore, in the present invention, the two rotation shafts are formed so as to be selectively rotatable in the forward and reverse directions by a ratchet mechanism capable of switching the rotation direction. Therefore, by selecting the rotation direction of the rotating shaft, the curtain can be tensioned to be in a stretched state, or conversely loosened to be in a relaxed state.

  The ratchet mechanism itself capable of switching the rotation direction used in the present invention is publicly known, and for example, a configuration similar to the ratchet mechanism described as a ratchet wrench in Utility Model Registration No. 3089062 can be used ( (See FIG. 3). That is, the ratchet mechanism has a ratchet tooth ring having teeth that are symmetrically formed on the outer periphery, two latches that mesh with the valley of the tooth at a location off the line passing through the central axis, and one of the latches is a tooth. The positioning member having a spring urging in the meshing direction and the operation lever of the positioning member can be used.

  The curtain can be stretched by winding both ends of the curtain around the rotary shafts and rotating the curtain in the winding direction, and the display provided on the curtain can be expanded. That is, the end of the curtain is wound around the rotating shaft and further rotated in the winding direction, whereby the tension can be strengthened so as to tension the curtain, and this can be operated on the two rotating shafts. It is. In particular, the curtain may have partial sagging and wrinkles, but since both are rotating shafts, if one of them is rotating and the sagging and wrinkles are not resolved, the other can be rotated and corrected. There is also an advantage that it can be easily stretched on a plane free from slack and wrinkles. Therefore, the operability is remarkably improved as compared with the conventional one having only one rotating shaft.

  Desirably, the surfaces of the two rotating shafts are provided with rough surfaces that come into contact with both ends of the curtain to generate frictional resistance. This is because the curtain is wrapped around a rotating shaft and attached, so even if it does not require a bag-like sewing process at the end of the curtain, it is easy to loosen if no means to stop the curtain is used. This is because this problem can be solved by using the frictional resistance as a curtain stop means. Therefore, in the present invention, it is recommended to provide a rough surface as a means for generating frictional resistance by contacting the curtain. As this rough surface, for example, a coarse sandpaper of about No. 12 to No. 400 can be used, and it is preferable to attach it to the rotating shaft. In addition, a resin having a surface with a high coefficient of friction having soft elasticity is also suitable, but it is not limited to the frictional resistance. For example, a rotating shaft is formed of a ferrous metal, and a magnet having a desired form is formed thereon. It is possible to magnetically adsorb it or use an adhesive tape to stop the end of the curtain.

  The curtain is formed longer than the installation interval of the two shafts, and if the plurality of display portions provided in the curtain length direction can be moved and changed by the rotation of both rotary shafts, Any display part can be selected and arranged between the two rotation axes. This display unit contains, for example, product drawings, campaign contents, and all other characters, symbols, designs, etc., and selects one of a plurality of displays and arranges it between two rotation axes. In addition, it is possible to move and change to another display depending on the day, and by using such a method, very high convenience can be obtained.

  In the industry, the above-described display unit or display thereof includes advertisements, advertisements and the like that may be simply called media. And when using the first display part of the plurality of display parts for a certain period, it is used by moving and changing to the second or third display part only on a special day during, for example, a sale. The usage method is also possible.

  Since the present invention is configured and operates as described above, it is not necessary to form attachment parts at both ends of the banner-type curtain by sewing work or the like, and both ends of the curtain are wound around both rotary shafts, and There is an effect that it is possible to provide a double-axis rotary type curtain tensioning device that can smoothly stretch the curtain by rotating in the winding direction. Further, according to the present invention, a curtain formed longer than the interval between the two rotating shafts is stretched on the two rotating shafts, and a plurality of display portions provided there are moved in the length direction. Since any display portion can be expanded and displayed as a curtain, an operation for changing the display portion is easy, and effective advertising and promotion can be performed.

  Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments. FIG. 1 shows a first example of a double-shaft rotary Makuhari apparatus 10 according to the present invention, and the illustrated one is of a banner type installed at an entrance of a convenience store (see FIG. 5). Therefore, in the illustrated apparatus 10, it is installed in a suspended manner on a ceiling portion such as a store entrance.

  In each figure, 11 is a curtain, and this curtain 11 is provided with a plurality of display portions 12-1 to 12-n provided in the length direction, and one display portion has an interval between two rotation axes. It consists of a plurality of sections that are the same or just fit in the interval between two rotation axes. Since the curtain 11 is pulled and stretched in the left-right direction, winding portions 13a and 13b are provided at both ends. It is only necessary to cut off the sheet-like curtain member at both ends of the curtain 11, and the winding portions 13a and 13b may be provided with marks indicating standard winding lengths. However, special sewing processing such as a bag shape is necessary. do not do.

  In addition, as shown in FIG. 1B, one display unit 12-1 among the plurality of display units 12-1 to 12-n has “XX campaign” which is the name of the event on the surface, and its content is a lottery. It has a display 14 composed of “Let's hit with XX tea × Hot XX!” And “product photo” indicating that the expression is true. FIG. 1C shows the back side of the curtain 11, and it is self-evident that the back side can also be used for the display unit although it is not displayed.

  Reference numerals 15 and 15 denote two rotating shafts installed at a required interval, and are installed in a suspended manner on the ceiling portion of the mounting base 16 on the upper end side of each of them. An example of the rotating shaft portion is as shown in detail in FIGS. 2 and 3. Inside the rotating shaft 15, there is a fixed shaft 17 fixed to the base portion, and the rotating shaft 15 switches the rotation direction. Is provided on the ratchet tooth ring 19 of the ratchet mechanism 18. The fixed shaft 17 is provided as a structure that reinforces to prevent the rotating shaft 15 from swinging. Moreover, it is also possible to attach this apparatus 10 not on the ceiling side but on the back side of the ceiling. The apparatus 10 is attached to the installation structure 20 behind the ceiling when the fixing bolt 16b for fastening the base 16a of the attachment base 16 or the like is not desired to be exposed to the outside.

  The ratchet mechanism 18 shown in the figure is incorporated in a casing, and the ratchet tooth ring 19 having teeth that are symmetrically formed on the outer periphery of the ratchet mechanism 18. A rocking member 21 having latches 21a and 21b, a positioning member 23 having a spring 22 for urging one of the latches 21a and 21b in the meshing direction with the teeth, and an operation lever 24 for the positioning member. The swing member 21 is rotatably supported on the casing by a central shaft 21c set inside the center between the two latches 21a and 21b, and is provided outside the central shaft-like distal end. A switching projection 21d is provided. That is, the teeth of the ratchet tooth ring 19 have a target shape, but the two latches 21 a and 21 b are engaged with the teeth of the ratchet tooth ring 19 at a position off the central axis passing through the center of the ratchet tooth ring 19 and the latch 21. This makes it possible to switch between one-way rotation and rotation direction.

  The rotating shaft 15 is integrally attached to the ratchet mechanism 18 at its upper end, and the outer surface of the rotating shaft 15 comes into contact with both ends (wrapping portions 13a and 13b) of the curtain to generate a frictional resistance. A surface 25 is provided. The illustrated rough surface 25 is formed by adhering No. 180 sandpaper to the outer surface of the rotary shaft 15, and the winding portions 13 a and 13 b are long enough to wind the rough surface 25 at least 2 to 3 times. Set to. An operation knob 26 is attached to the lower end of the rotation shaft 15 for the rotation operation.

  FIG. 4 shows Example 2 in which the apparatus 10 is configured to include a mounting member 27 in a building. The mounting member 27 of Example 2 is made of a so-called mold material having a certain cross-sectional shape, and extends along its longitudinal direction. A plurality of channel portions 28 having a substantially T-shaped cross-sectional shape are provided, and a part of the channel portions 28 is opened on the surface of the member. A stop plate 29 having a female screw portion 29a can be inserted into the channel portion 28, and a bolt 29b is inserted into a bolt hole 16b opened in the base 16a of the mounting base portion 16, and the female screw portion of the stop plate 29 is inserted through the channel portion opening. The same operation is performed for all the bolt holes 16b and the rotary shaft 15 is attached.

  According to the configuration of FIG. 4, since the two rotating shafts 15 can be mounted and placed in advance using the mounting member 27, the two rotating shafts 15 and 15 installed at a required interval are provided. Before attaching the two-axis rotary type Makuhari apparatus 10 for attaching the both ends (wrapping portions 13a and 13b) of the curtain 11 to the rotary shafts 15 and 15 and extending the curtain, It can be provided in a completed form. The length of the plate-like attachment member 27 can be arbitrarily selected, and the installation interval between the two rotary shafts 15 and 15 can be changed by loosening the bolt 29b and moving it together with the base 16a.

  To supplement the explanation of the installation, removal, replacement, etc. of the curtain 11, first of all, the winding portion 13 a at one end of the curtain 11 is first wound slightly tightly using the rough surface 25 on one rotating shaft 15. Then, the winding portion 13b at the other end is wound around the other rotating shaft 15 in the same manner using the rough surface 25. In this state, the curtain 11 is slightly loosened, so that the ratchet mechanism 18 on one side is switched so that it does not rotate even if the curtain 11 is pulled in the center direction, and then the rotation shaft on the other side in the direction in which the curtain 11 is pulled. Rotate 15 and go. At the end of this operation, the ratchet mechanism 18 of the other rotating shaft 15 is not reversed by the tension of the curtain 11, so that if the hand is released as it is, the curtain 11 becomes an appropriate tension and the plane is kept in a tension state. . In order to remove, the ratchet mechanism 18 is switched so as to move in the central direction on the side where the curtain 11 is removed, the rotary shaft 15 on the same side can be rotated, and the curtain 11 can be pulled in the central direction as it is.

  The double-axis rotary Makuhari apparatus 10 of the present invention stretched as described above is installed on the ceiling of the eaves in a convenience store store 30 or the like, and used as a banner-type advertisement or advertising device. Users can be informed of the start of handling new products and the campaign implementation period (see FIG. 5). Further, when a special sale is performed during the campaign advertisement, the rotary shaft 15 on the side of the next display unit 12-2 is made rotatable, and the rotary shaft 15 on one side is turned on. Rotate and change the campaign advertisement display unit 12-1 to the next display unit 12-2. Thus, even if the curtain 11 is not replaced, the display of the curtain 11 can be changed very easily, and the work using a platform such as a stepladder can be remarkably reduced.

  In addition, when the height of the eaves 31 of the store 30 is too high to attach the present apparatus 10, as shown in Example 3 of FIGS. It can be used as 10 mounting locations. In this case, the apparatus 10 is attached using a bracket having an appropriate shape as the attachment member 33. In the example of FIG. 7, both sides rotate on the upper frame 33a of the attachment member 33 having a U-shaped side surface. The base 16 of the type Makuhari apparatus 10 is attached, the rotary shaft 15 is attached to the lower frame 33b, and at least two sets can be attached to the vertical frame 32 with bolts 34 at an appropriate interval. Also in Example 3, since the two rotating shafts 15 can be mounted and placed in advance using the mounting member 33, the apparatus 10 of the present invention can be handled as a unit including the mounting member 33. The flexibility of attachment can be improved together with Example 2 of 4. Since the configuration in each part of Example 3 and the method of extending curtain 11 are the same as in Example 1 or Example 2, reference numerals are used and detailed description will not be repeated.

  Since Example 3 shown in FIGS. 6 and 7 can be implemented in combination with Example 2 in FIG. 4, an example thereof is shown in FIG. 8A. If it does in this way, the rotating shaft 15 can be arrange | positioned in any position in the range of the length of the attachment member 27. FIG. However, the attachment member 33 ′ used for attaching the device 10 to the vertical stand 32 or the like is not a U-shape, but is an inverted L-shape only at the top, and the lower end of the rotating shaft may be free as in the first example. FIG. 8B shows an example in which the rotating shaft 15 is made of an iron-based metal and is magnetically attracted to the rotating shaft 15 by using a magnet having a desired form so that the end of the curtain 11 is sandwiched. In the example of FIG. 8B, a sheet-like magnet 36 in which magnetic powder is mixed in rubber is used as a curtain stopper, and the curtain 11 wound around the iron rotating shaft 15 is fixed by using a plurality of sheet-like magnets 36. . When a bar-shaped magnet 36 ′ having a length that can suppress the end of the curtain 11 with a single magnet is used, the end of the curtain 11 can be suppressed without being uneven.

  According to the present invention, as described above, the biaxial rotary Makuhari apparatus 10 can be attached to the structure of a building such as an eave, an eave, a vertical structure, a wall surface, or any other part. The apparatus 10 of the present invention can originally stretch the curtain 11 with an arbitrary tension by using at least two sets of the rotary shafts 15 having the ratchet mechanism 18, and an advertisement formed on the curtain 11, Any part of the display unit 12 such as an advertisement can be freely selected and displayed. This feature is combined with the mounting members 27 and 33 of the above-described examples 2 and 3, and thus has a higher practicality. It will be a thing.
