BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display stand capable of holding the upper and lower ends of a flexible display sheet formed by using a cloth, a flexible synthetic resin sheet or the like in a state where the display sheet is stretched. It is a thing.

[0002]

2. Description of the Related Art An upper and lower end portions of a display sheet made of cloth or the like on which an advertisement is displayed can be detachably held, and a tension can be applied to the display sheet so that the display sheet is stretched in the vertical direction. As a simple type of display stand, the FRP projecting upward from the pedestal or support
Various types of structures using a tension bar such as those manufactured are provided.

An example of this will be described with reference to FIGS. 27 to 29. The display stand a has a pedestal member b made of a long pipe in the front-rear direction and a front end of a display sheet c made of cloth or the like on which an advertisement is displayed. A lower C-shaped holding piece f that is open to the front and is long in the left-right direction is provided for detachably holding the left-right holding bar e attached to the end portion d of the pedestal member. A pipe-shaped support g was erected at the rear end of b. A tension bar h, which can be elastically curved and deformed, is housed in the column g so as to be able to be taken in and out in the length direction of the column g, and the upper end of the tension bar h above the display sheet c. In order to detachably retain the left-right holding bar k attached to the end j, the upper C-shaped holding piece m that is open obliquely upward and is long in the left-right direction is provided. It was

As shown in FIGS. 28 to 29, the upper and lower end portions j and d of the display sheet c are folded back in a bag shape, and the edge o of the folded piece n faces the front side. Upper and lower cylindrical insertion portions q and r are formed by sewing to the portion p, and the upper and lower holding bars k and e can be inserted into the cylindrical insertion portions q and r. The way to form the upper and lower cylindrical insertion portions q and r is to cut the center portions of the upper and lower end portions j and d of the display sheet c as required, and to form the folded-back pieces n that form the left and right portions of the notch portion s. , N are folded back to the rear side, and the edges o, o of the folded back are sewn to the front part p opposite thereto, and the upper and lower openings t, u formed by the cutout s The rear sides v and w of the central portions of the upper and lower holding bars k and e are exposed.

However, in order to hold the display sheet c in a vertically stretched state by the display stand a having such a configuration, the tension bar h is elastically bent while the tension bar h is pulled up. Transform it,
The rear sides v and w of the upper and lower holding bars k and e in an exposed state are elastically attached to the upper and lower C-shaped holding pieces m and f. Then, the urging action of the tension bar h by this gives a vertical tension to the display sheet c, so that the display sheet c is stretched in the vertical direction.

[0006]

However, when the display stand a utilizing the elastic bending deformation of the tension bar h is used, there are various problems. Figure 27
An example of the display stand shown in FIG. (1) Since the biasing force associated with the elastic bending deformation of the tension bar h is used as a means for applying the tension to the display sheet c, the tension is insufficient when the display sheet c has a long vertical length. As a result, the display sheet may be loosened, and the holding of the display sheet tends to become unstable. Conversely, when the vertical length of the display sheet c is short, the bending state of the tension bar h becomes strong and the tension becomes excessive.
When the holding bar k attached to the upper end of the display sheet is removed from the upper C-shaped holding piece m, a strong repulsion phenomenon occurs in which the tension bar h rapidly returns from the curved state to the straight state, which may cause an injury. There was a risk to

(2) When the display stand a utilizing the tension of the tension bar h is used, the tension that can be applied to the display sheet c is limited. Was easy to destabilize. Also, when the wind blows, the C-shaped holding pieces m and f are pressed by the wind pressure.
And the holding bars k and f may be disengaged, and if the display stand falls down due to wind, the impact may cause the holding bar to be disengaged from the C-shaped holding piece, and the tension bar h may be removed. There was a danger of suddenly returning with a strong restoring force. As described above, the conventional display stand is unstable in the wind, and thus has a problem that it is difficult to use outdoors and its use is limited.

(3) Further, when attaching the upper holding bar k to the upper C-shaped holding piece m provided on the upper end of the tension bar h, the tension bar h having a strong spring property must be forcibly deformed by bending. Since it does not happen, it is difficult to install, and if the tension bar elastically returns to a straight line due to failure to install, there is a risk of injury, etc.
The work was dangerous.

(4) Further, in the conventional display device, in order to attach the C-shaped holding pieces m and f to the holding bars k and e, as shown in FIGS. However, for this purpose, the folding pieces n, n are manually cut as required to form the cutout portions s,
The step of forming s is required, and the folded piece n on the right side and the folded piece n on the left side of the cutout portion s must be individually folded and sewn to form the cylindrical insertion portions q and r. However, there is a problem in that the manufacturing efficiency of the display sheet c is poor and the cost is increased because it takes a lot of time and labor. Further, there is a problem that the cutout portion is not always correctly positioned and formed.

(5) Further, since the openings t and u are formed in the cylindrical insertion portions q and r, the rigidity at the portions is weakened, and the upper end portion and the lower end portion of the display sheet c sag in the left and right directions at the opening portions. There is also a problem in that the wrinkles w in the vertical direction as shown in FIG. 30, for example, occur on the display sheet due to this, and the display effect of advertisements is impaired. An object of the present invention is to provide a display stand that can solve such problems.

It is also possible to use a combination of a holding portion main body and a cover member such as a thing. Further, the upper holding part may be constructed by inverting the lower holding part shown in the above-mentioned embodiment in an upside down manner.

(3) When the lower holding portion 6 is configured as the insertion hole portion 39 having the through groove portion, the insertion hole portion 39 is for minimizing the passage length on the lower end side 119 of the display sheet 7. For example, as shown in FIG. 18, it is preferable that the pedestal 2 is formed relatively short in the central portion in the left-right direction (for example, formed as short as about 10 cm), but only on both side portions of the pedestal,
It may be formed over the entire length of the pedestal in the left-right direction.

(4) When the lower holding portion 6 for holding the lower end portion of the display sheet is constituted by the accommodating recess 16 having the above-described configuration and the retaining member 23 combined with this, the retaining As shown in FIG. 5, the member 23 is inserted from the lower side to the upper side and attached to the pedestal 2, and
As shown in FIG. 3, the holding member 23 may be configured to be insertable into the guide groove 126 provided in the lengthwise direction of the accommodation recess 16.

(5) When the through groove portion is constituted by the holding member 23 having the holding piece 33 having a C-shape as shown in FIG. 5, the holding piece 33 is formed as shown in FIG. The upper end side may be configured to project from the rear side portion 32 of the accommodation recess toward the front side portion 31. In this case, a through groove portion 41 is formed between the tip end edge 40 on the upper end side and the front side portion 31 of the accommodation recess 16 facing it.

(6) FIG. 25 shows an embodiment in which the holding recess 6 is omitted and the lower holding portion 6 is formed. In order to form the through groove portion 41, the holding portion 127 is opposed to the holding piece 127. The case where the standing wall portion 129 is provided so as to project from the pedestal 2 is shown.

(7) The lower holding portion 6 for detachably attaching the lower end portion 10 of the display sheet 7 may be provided on the pedestal 2 as described above, or may be provided on the lower end side of the column. . In this case, for example, a configuration in which the upper holding portion 5 shown in FIG. 14 is provided upside down can be adopted.

(8) In the display stand according to the present invention, the upper holding part 5 may be fixed to the column 3 and the lower holding part 6 may be vertically movable with respect to the column 3. In this case, a required tension can be applied to the display sheet 7 by moving the lower holding portion 6 downward and fixing the state.

(9) In order to apply tension to the display sheet,
The means for moving the upper or lower holding portion up and down can adopt not only the screw method as described above, but also a lever operation by applying a link mechanism, for example.

(10) As a means for detachably holding the upper and lower ends of the display sheet in the upper and lower holding portions, a holding bar is provided in the cylindrical insertion portion provided in the display sheet as shown in the above embodiment. It is not specified to be inserted and held detachably via the holding bar, but the upper and lower end portions of the display sheet formed of cloth, synthetic resin sheet or the like are detachably held as they are. A configuration may be adopted.

[0053]

Since the display stand according to the present invention is constructed so that the upper and lower end portions of the display sheet can be detachably held by the upper and lower holding portions, the display sheet can be replaced unlike the conventional standing signboard. It is easy to obtain the following excellent effects. (1) In the case of the display stand according to the present invention, the upper and lower end portions of the display sheet are held by the upper and lower holding portions, the upper holding portion is moved upward with respect to the column, or the lower holding portion is held. By moving the column downward with respect to the column, tension can be applied to the display sheet by the amount of movement so that the display sheet is stretched in the vertical direction. Therefore, unlike the conventional display stand that applies tension to the display sheet by the urging action associated with the curved deformation of the tension bar, there is no inconvenience that the tension bar having a strong spring property must be elastically deformed. Tension can be applied easily and safely. When the tension bar is used, the tension bar may be disengaged when an external force such as wind pressure is applied to the mounting portions of the tension bar with respect to the upper and lower ends of the display sheet. In the state where the required tension is applied to the display sheet, since the space between the upper and lower holding portions is fixed, such a problem can be eliminated, and the state in which the tension is applied can be stably maintained. . Therefore, the display stand according to the present invention can be used not only indoor use but also outdoors as in the conventional display stand using the tension bar.

(2) Further, in the case of the display stand according to the present invention, since it is possible to set a large amount of vertical movement of the upper holding portion or the lower holding portion with respect to the column, the vertical length is different. Tension can be surely applied to the display sheet so that the display sheet is stretched in the vertical direction. Since the conventional display stand uses the elastic deformation of the tension bar, there is a problem that the tension is not applied to the display sheet with a large vertical length. In the case of a short display sheet, the tension bar must be elastically deformed more strongly.Therefore, when the tension bar is attached to or detached from the upper and lower end portions of the display sheet, the tension bar changes from a curved state to a straight state. There was a risk of injuring the worker due to a strong repulsive action when trying to return to. On the other hand, according to the present invention, since the upper and lower end portions of the display sheet are held by the upper and lower holding portions, tension can be applied to the display sheet and the tension can be released.
The display sheet can be attached and removed safely and reliably, and the danger as described above can be eliminated.

(3) The lower holding portion has an insertion hole portion for inserting the holding bar attached to the lower end of the display sheet in the left-right direction, and the insertion hole portion is provided above the insertion hole portion. When the lower end side of the display sheet is configured to have a through groove portion that passes through in the left-right direction, when the lower end portion of the display sheet is held by the lower holding portion, one end side of the insertion hole portion By sliding the holding bar toward the end side together with the lower end side of the display sheet (that is, with the lower end of the display sheet attached to the holding bar), the lower end side of the display sheet is moved to the through groove portion. The lower end portion of the display sheet can be easily held by the lower holding portion while passing through. On the contrary, from this holding state, the holding bar can be easily removed from the insertion hole by moving the holding bar in the left-right direction, which can improve the operability. Since the groove width of the through groove is set so that the holding bar does not slip out, the holding bar is inserted into the insertion hole and tension is applied to the display sheet. There is no risk that the end of the will come off the lower holding part.

(4) In the conventional display stand using the tension bar, when attaching the end of the tension bar h and the end of the pedestal member b to the upper and lower ends of the display sheet, as shown in FIGS. As shown in FIG. 5, it was necessary to provide a cutout portion s at the end of the display sheet in the mounting portion and expose the holding bar at the cutout portion. There was a troublesome work in that the display sheet had to be specially processed. On the other hand, according to the present invention using the through groove, it is not necessary to provide such a notch, and as shown in FIG. 17, for example, the edge of the display sheet is folded back into a bag shape so that the edge is cut off. Since it is only necessary to sew, it is possible to improve the manufacturing efficiency of the display sheet and reduce the manufacturing cost.

(5) A holding member provided with a housing recess extending in the left-right direction on the upper surface of the pedestal, and a holding piece protruding from one side part on the front and rear of the housing recess toward the other side part. When this is combined with this to form the insertion hole portion having the through groove portion, the holding bar attached to the lower end portion of the display sheet can be housed in the accommodation recess, and the holding bar in the housed state can be held. Since the bar can be inserted through the insertion hole,
It is possible to prevent the holding bar from projecting to the upper surface side of the pedestal and spoiling the appearance. Further, it is not necessary to form a standing wall portion 129 as shown in FIG. 25 for forming the insertion hole portion, and it is possible to prevent the holding member from being largely projected to the upper surface side of the pedestal, and thus the pedestal can be handled easily. It is possible to improve the safety and improve the aesthetics of the pedestal.

(6) When the holding bar is inserted into the insertion hole portion having the through groove portion, the insertion hole portion is provided in the left and right portions of the pedestal (for example, having a left and right width of about 45 cm), or of the pedestal. Although it can be provided over the entire length in the left-right direction, in the case of such a configuration, compared to the case where it is provided only in the central portion in the left-right direction of the pedestal as in the above-described embodiment, there are two through groove portions. Or, the length of the through groove becomes longer. Therefore, when moving the holding bar in the left-right direction while passing the lower end side of the display sheet through the through groove,
Although the edge portion of the through groove is easily caught on the display sheet, there is a problem that it is difficult to insert the holding bar smoothly.
When the insertion hole is provided in the center of the pedestal in the left-right direction relatively shortly, such a problem of the display sheet being caught is unlikely to occur, and the holding bar can be smoothly inserted into the insertion hole.

(7) As a means for holding the lower end portion of the display sheet in the lower holding portion, when the above-mentioned structure in which the holding bar is inserted into the insertion hole portion having the through groove portion, There is an advantage that the troublesome operation accompanying the attachment and detachment of the cover member is unnecessary, as in the case where the lower holding unit is configured as a holding unit including a holding unit main body and a cover member as shown in FIG. 11, for example.

(8) By arranging the insertion hole portions having the through groove portions vertically, and inserting the upper and lower holding bars into the insertion hole portions, the upper and lower end portions of the display sheet can be attached to and detached from the upper and lower holding portions. When the structure to hold is adopted, for example, when the lower holding bar is attached to the lower insertion hole, and the upper holding bar is attached to the upper insertion hole by sliding in the left-right direction, As shown in FIG. 26, the display sheet 7 is
It is necessary to pass the upper holding bar 110 through the insertion hole 130 in the direction of the arrow in an unnatural oblique state, which causes a problem that it is difficult to smoothly perform the passing work.
By including the holding portion main body 80 and the cover member 81 as shown in FIG. 11, for example, the display sheet 7 is kept in the natural vertical direction as shown in FIG. The upper end portion 9 of the display sheet is applied to the holding portion main body 80 via the holding bar 110, and the cover member 81 is attached thereafter, so that the upper end portion of the display sheet is held by the upper holding portion without difficulty. There is an advantage to get.

(9) A mounting hole penetrating in the vertical direction is formed in the pedestal, and a holding member separate from the pedestal is passed through the mounting hole from the lower side to the upper side, and the holding member and the accommodating concave portion. When a configuration in which the insertion hole portion having the through groove portion is formed between the side portion of the base and the side portion of the place is adopted, even if the pedestal has a low rigidity such as that formed by blow molding, There is an advantage that a strong insertion hole can be formed by the cooperation of the pedestal and the separate holding member.

(10) When the accommodation recess is provided in the pedestal and the insertion hole with the through groove is formed between the side portion and the holding member, the upward protrusion of the holding member can be made inconspicuous. ,
Further, it is not necessary to provide the pedestal with the standing wall portion for forming the insertion hole portion with the holding member, and the aesthetics of the pedestal can be improved by these.

(11) When the structure is such that the lower end of the display sheet is detachably held by the lower holding portion provided on the pedestal, not by the pillar, the lower end is the lower end of the pillar. The stability based on the weight of the pedestal has an advantage that the lower end portion of the display sheet can be more stably held, as compared with the case of being attached to.

(12) By adopting a screw system as a means for moving the upper holding part up and down with respect to the support, tension can be easily and surely applied to the display sheet, and the tension is applied. The state can be stably maintained without being affected by an external force such as wind pressure.

(13) The upper and lower ends of the display sheet are folded back into a bag shape and sewn to form a tubular insertion portion, and a holding bar is inserted into the tubular insertion portion, and the upper and lower holding bars are inserted. When the display sheet is held by the upper and lower holding portions, the lower end side of the display sheet is inserted into the through groove portion (lower groove portion) 41, and the upper end side of the display sheet is inserted into the groove portion (upper groove portion) 103, and As shown in FIG. 19, the through groove portion (lower groove portion) 41 is sewn to the lower tubular insertion portion 111b at the sewing portion 131.
By adopting a configuration in which the groove portion (upper groove portion) 103 is positioned above the sewing portion 132 of the upper cylindrical insertion portion 111a as shown in FIG. Even when the edge portion 133 of the groove portion comes into contact with the upper and lower portions of the display sheet 7, the contact is with respect to the portion having relatively high rigidity formed by folding, and forms the upper and lower sewing portions. Since it does not come into contact with the display portion having a relatively low rigidity, it is possible to prevent the display sheet from being wrinkled in the vertical direction. If the edge portion of the groove portion comes into contact between the upper and lower sewn portions, since the contact portion has low rigidity, wrinkles in the vertical direction may occur due to the contact between the edge portions. When the wrinkles in the vertical direction are generated as described above, the display effect may be deteriorated, but such a problem can be prevented by the configuration as described above.
