  Hereinafter, a first embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 1, the display device 10 is for holding an exhibit 20 and includes a holding mechanism that holds the exhibit 20 and a support mechanism that supports the holding mechanism. The holding mechanism includes a vent pipe 11 having a gas flow path 11R through which gas can flow, a valve 12 provided in the vent pipe 11, a balloon 13 made of an elastic material and capable of filling the inside, and a gas inside. And a fixing ring 14 that can fix the balloon 13 in a state of being filled to the vent pipe 11. The support mechanism is a support mechanism 16 that supports the vent pipe 11. The vent pipe 11, the valve 12, and the fixing ring 14 form a closing mechanism that closes the balloon opening 13 </ b> X of the balloon 13.

  The support mechanism 16 includes a base 16A and a support column 16B extending upward from the base 16A. The support column 16B includes a lower support column 16BL having a lower end attached to the base 16A, and an upper support column 16BU in which a vent pipe support hole (not shown) for supporting the vent pipe 11 is formed. The vent pipe support hole penetrates from the front surface to the back surface of the upper column 16BU.

  As shown in FIG. 2, a column insertion hole 16BB into which the lower portion of the upper column 16BU can be inserted opens on the upper surface of the lower column 16BL. The column insertion hole 16BB extends downward from the upper surface of the lower column 16BL. When the lower portion of the upper column 16BU is inserted into the column insertion hole 16BB, the upper column 16BU is automatically slidable in the vertical direction using the column insertion hole 16BB as a guide (see FIG. 1).

  As shown in FIG. 2, an insertion hole 16BC into which the screw 30 can be inserted is formed on the side surface (for example, the side surface on the back side) of the lower support column 16BL. Further, screw holes 16BD that can be screwed with the screws 30 are arranged at a constant pitch in the vertical direction on the side surface (for example, the side surface on the back side) of the upper support column 16BU. By screwing the screw 30 and the screwing hole 16BD through the insertion hole 16BC, the upper column 16BU can be fixed to the lower column 16BL in a state where the height of the vent pipe support hole is maintained constant. .

  The vent pipe 11 is fixed to the upper support column 16BU in a state of being inserted into the vent pipe support hole. The vent pipe 11 may be slidable while being inserted into the vent pipe support hole. In this case, the vent pipe 11 may be fixed to the upper support column 16BU using a separate fixing tool.

  The ventilation pipe 11 has an inlet side pipe part 11A, an outlet side pipe part 11B, and a curved pipe part 11C that connects the inlet side pipe part 11A and the outlet side pipe part 11B. A valve 12 is provided on one end side of the inlet side pipe portion 11A. The curved tube portion 11C connects the other end side of the inlet side tube portion 11A and one end side of the outlet side tube portion 11B. An outlet 11Y of the vent pipe 11 opens on the other end side of the outlet side pipe portion 11B.

  The valve 12 allows the inlet 11X of the vent pipe 11 to be opened and closed. When the valve 12 is in the “closed” state, the inlet 11X is closed. When the valve 12 is in the “open” state, the inlet 11X is opened. The valve 12 is not particularly limited as long as it can open and close the gas flow path 11R, and includes, for example, an American valve, an English valve, and a French valve provided on a bicycle tire or the like. The valve 12 only needs to be able to open and close the gas flow path 11R. In addition to the valve 12 that can open and close the inlet 11X of the vent pipe 11, the valve 12 that can open and close the outlet 11Y, The thing which can open and close the middle part of the road 11R may be used.

  11 A of inlet side pipe parts inserted in the vent pipe support hole of upper support | pillar 16BU are distribute | arranged with the diagonal attitude | position which becomes upward as it goes to the other end side from one end side. The inlet 11X is detachably attached to the air supply port 35X of the air pump 35 (see FIG. 3). Returning to FIG. 2, the outlet side pipe portion 11 </ b> B is arranged to extend in the vertical direction, and the outlet 11 </ b> Y opens at the lower end. The ventilation member is not limited to the ventilation pipe 11 and may be a ventilation block formed in a block shape and incorporating the gas flow path 11R.

  The material for forming the base 16A, the support column 16B, and the vent pipe 11 is not particularly limited, and may be any metal or plastic. It is preferable that the base 16 </ b> A has a larger mass than the exhibit 20 in terms of securing the stability of the exhibit 10 in a state where the exhibit 20 is displayed. From this point, the base 16A is preferably a metal. Further, the display tool 10 is preferably transparent. From this point, it is preferable that the material for forming the columns 16B and the ventilation pipe 11 is a transparent plastic.

  The balloon 13 has a balloon tube portion 13A that has a balloon opening 13X at one end and through which gas can flow, and a balloon bag portion 13B that is connected to the other end of the balloon tube portion 13A and is filled with gas. The outlet opening 11B can be inserted into the balloon opening 13X. The shape of the balloon bag portion 13B filled with gas is not particularly limited, but may be a columnar shape in addition to a sphere as illustrated. Moreover, the formation material of the balloon 13 should just have elasticity (for example, rubber | gum). And the intensity | strength of the balloon 13 should just be able to endure the weight of the exhibit 20.

  The fixing ring 14 has an insertion hole into which the outlet side pipe portion 11B can be inserted. Then, by inserting the outlet side pipe portion 11B into the insertion hole, the fixing ring 14 is detachably fitted to the outlet side pipe portion 11B. It is preferable that the outer diameter of the lower part of the outlet side pipe portion 11B gradually decreases, that is, tapers toward the tip, that is, the outlet 11Y. Thereby, the fixing ring 14 can be reliably fitted to the outlet side pipe portion 11B.

  Next, a method for attaching the exhibit 20 to the exhibit 10 will be described.

  First, as shown in FIG. 2, the outlet side pipe portion 11B is inserted into the balloon opening 13X. The fixing ring 14 is fitted to the outlet side pipe part 11B so as to sandwich the peripheral part of the balloon opening 13X, that is, the balloon pipe part 13A among the balloons 13 (see FIG. 3). Thus, the fixing ring 14 can fix the balloon 13 to the ventilation pipe 11.

  Next, the exhibit 20 is held so that the balloon 13 fixed to the ventilation pipe 11 is inserted from the opening 20 </ b> X of the exhibit 20. Thereby, the balloon 13 is located in the hollow part 20C of the exhibit 20 that communicates with the opening 20X. As a method of holding the exhibit 20 so that the balloon 13 is inserted into the opening 20X, the exhibit 20 may be held by hand, or may be displayed using a separate pedestal installed on the base 16A. The object 20 may be held.

  Then, the valve 12 is set to the “open” state, and the inlet 11X is connected to the air supply port 35X of the air pump 35. Thereafter, when the air pump 35 is driven, the gas sent out by the air pump 35 is introduced into the balloon 13 via the gas flow path 11R. As a result, the balloon 13 located in the hollow portion 20C is inflated. When air of a predetermined flow rate is introduced into the balloon 13, the outer surface of the balloon bag portion 13B pushes the inner surface 20N of the exhibit 20 by the pressure of the gas filled in the balloon bag portion 13B (see FIG. 1). . For example, when the exhibit 20 has a shape as shown in FIG. 1, the upper portion (hereinafter referred to as the upper outer surface) 13BS of the balloon 13 is a portion that narrows toward the opening 20X in the hollow portion 20C of the exhibit 20. push. That is, the annular upper outer surface 13BS contacts the inner surface 20N of the exhibit 20. The balloon tube portion 13A supports the exhibit 20 together with the balloon bag portion 13B. In this way, the balloon 13 can hold the exhibit 20 via the vent pipe 11.

  Finally, the valve 12 is set to the “closed” state, and the inlet 11X is removed from the air supply port 35X of the air pump 35.

  Next, a method for removing the exhibit 20 from the display tool 10 will be described.

  First, when the valve 12 is set to the “open” state while holding the exhibit 20, the gas filled in the balloon 13 is released, and the support of the display tool 10 by the balloon 13 is released. In this way, the exhibit 20 can be removed from the display tool 10.

  In this way, the exhibit 10 can hold the exhibit 20 by using the balloon 13 that supports the inner surface 20N of the exhibit 20, and thus there is no need to place the exhibit 20. In other words, the display tool 10 can be held in a state where the lower portion 20U of the exhibit 20 is not in contact. Therefore, according to the display tool 10, it is possible to display the exhibit 20 having a shape that is difficult to stand on its own.

  Moreover, according to the display tool 10, since the exhibit 20 is held using the balloon 13 filled with gas, the outer surface of the balloon 13 can be deformed according to the shape of the inner surface 20N of the exhibit 20, and the deformation In this state, it is possible to apply a certain pressure to the inner surface 20N of the exhibit 20, so that the exhibit 20 having various shapes can be held.

  Furthermore, since the exhibit 20 held in the display tool 10 is not in direct contact with the vent pipe 11 and the support mechanism 16, even when the vent pipe 11 and the support mechanism 16 vibrate, the vibration of the vent pipe 11 and the support mechanism 16. Is not transmitted directly to the exhibit 20.

  And the display tool 10 does not need to mount the exhibit 20 regardless of an exhibit that is difficult to be independent or an exhibit that can be independent. For this reason, the exhibit 10 can hold the exhibit 20 in such a manner that the entire exhibit 20 can be viewed up to the bottom of the exhibit 20 in addition to the head and sides of the exhibit 20.

  In addition, the exhibit 20 held by the display tool 10 is attached to the vent pipe 11 and the support mechanism 16 via the balloon 13. For this reason, even when the vent pipe 11 and the support mechanism 16 vibrate, the vibration of the vent pipe 11 and the support mechanism 16 is attenuated by the vibration of the balloon 13 in front of the exhibit 20. As a result, the vibration of the exhibit 20 is suppressed.

  In addition, as described above, the operation for removing the exhibit 20 from the display tool 10 may be performed simply by performing the “open” operation of the valve 12 while holding the exhibit 20. For this reason, the removal work of the exhibit 20 is also easy.

  A protrusion may be provided on the upper outer surface 13BS of the balloon bag portion 13B. Thereby, the retention strength with respect to the exhibit 20 improves. The shape of the protrusion may be formed in an annular shape so as to surround the balloon opening 13X. One or a plurality of annular protrusions may be provided. A plurality of protrusions may be scattered. The display device 10 may be held in a state where the lower part 20U of the exhibit 20 is not in contact, or may be held in a state where the lower part 20U of the exhibit 20 is in contact with the base 16A.

  In addition, as a shape of the exhibit which the display tool 10 can hold | maintain, what has an opening part, such as a cylinder shape, should just be. Moreover, the exhibit 21 shown in FIG. 4 may be used as the shape of the exhibit 20 that can be held by the exhibit tool 10. The exhibit 21 includes a base portion 21A and a plurality of standing portions 21B provided so as to stand up from the periphery of the base portion 21A. In this case, the portion surrounded by the tips of the plurality of upright portions 21 </ b> B becomes the opening 21 </ b> X of the exhibit 21. And gas is supplied to the balloon 13 inserted from the opening 21X, and the balloon 13 is inflated. As a result, on the surface of the balloon 13, the portions that are in contact with the inner surface 20 </ b> N of the exhibit 20 are arranged apart from each other in the circumferential direction.

  In the said embodiment, although the fixing ring 14 was used as a method of fixing the balloon 13 to the vent pipe 11, this invention is not limited to this. For example, instead of the fixing ring 14, a fastening band that connects the balloon opening 13X of the balloon 13 with the outlet side pipe portion 11B inserted into the balloon pipe portion 13A together with the outlet side pipe portion 11B may be used.

    Moreover, in the said embodiment, although the holding mechanism which has the vent pipe 11, the valve | bulb 12, the balloon 13, and the fixing ring 14 was used, this invention is not limited to this, The opening and closing of the balloon 13 and the balloon opening 13X What is necessary is just to have a plug unit capable of.

  In the above embodiment, the balloon 13 is filled with gas, but the present invention is not limited to this, and the balloon 13 may be filled with liquid.

  Next, a second embodiment of the present invention will be described.

Further, the branch plate 65B is formed in a curved shape so as to be convex toward the slide bar 65A. The tip of the slide bar 65A is fixed to the convex surface of the branch plate 65B, and the contactors 65C are provided at both ends of the concave surface of the branch plate 65B. The branch plate 65B may be a flat plate, or may be curved so as to be concave toward the slide bar 65A.

  The material for forming the contact 65C is preferably an elastic material (for example, rubber). The shape of the contact 65C is a spherical shape, but is not limited to this, and may be a shape having a spherical surface or other shapes (for example, a cube, a rectangular parallelepiped, etc.).

  As shown in FIG. 7, the support mechanism 62 has substantially the same configuration as the support mechanism 16, and only the parts different from the support mechanism 16 will be described, and description of other parts will be omitted. The support mechanism 62 includes a base 62A and a support column 62B extending upward from the base 62A. The column 62B includes a lower column 62BL having a lower end attached to the base 62A, and an upper column 62BU having a slide insertion hole 62BA (see FIG. 5) into which the slide bar 65A is inserted at the upper portion. The slide insertion hole 62BA extends in a substantially horizontal direction and penetrates from the front surface to the back surface of the upper support column 62BU. By inserting the slide rod 65A into the slide insertion hole 62BA, the outer surface abutment mechanism 65 uses the slide insertion hole 62BA as a guide to contact the outer surface 70G of the exhibit 70 (see FIG. 6) and the exhibit. It is slidable between a distance from the outer surface 70G of the 70 (see FIG. 5).

  As shown in FIGS. 5 and 7, an insertion hole 62BC for a screw 80 is provided on the side surface of the upper support 62BU, and screw holes 65AA that can be screwed with the screw 80 are provided at a predetermined pitch on the slide bar 65A.
