Description

  The present invention relates to a display case (may be referred to as a display case) that is installed in a museum, an art gallery, a store, etc. and used to display various articles, and in particular, is a bulky and square display case that is self-supporting on the floor. Is a suitable target.

  There are various types of display cases, one of which is a self-supporting type installed on the floor. In this free-standing display case, the display space is generally surrounded by four glass plates. In other words, a rectangular parallelepiped display space is constituted by four glass plates. In addition, the self-standing display case has a height approximately equal to or higher than that of a general adult, and the bulky type generally includes a lamp on the ceiling (for example, Patent Document 1).

  In addition, in the case of a square self-supporting type display case having a high height, among the four glass plates constituting the periphery of the display space, the three glass plates constituting the front and the left and right side surfaces are adjacent to each other. As a whole, the glass plate is continuous in a U-shape in plan view, and one glass plate constituting the back surface is a sliding or horizontal rotating door for taking in and out articles (for example, a patent) Reference 2).

  It is necessary to supply power to the lamp in a self-supporting display case with a lamp on the ceiling, but the building power is drawn from the floor to the base (or display stand), so the base to the ceiling Although it is necessary to pull up the power cable, most of the periphery of the display space is made of a glass plate. Therefore, it has been devised to wire the power cable from the base portion to the ceiling portion in a state that is not as conspicuous as possible, and conventionally, the method shown in FIG. 4 has been adopted.

That is, in the method of FIG. 4A, a corner pipe-like corner column 21 is erected at each corner portion of the display space, and the power cable C is wired inside the corner column 21 and the end surface of the glass plate 22 is provided. 4B is adhered to the corner column 21 with an adhesive (caulking agent) 23. On the other hand, in the method of FIG. 4B, the end surfaces 22a of the adjacent glass plates 22 are obliquely seen in plan view so as to be parallel to each other. The end surfaces 22a of the adjacent glass plates 22 are bonded with an adhesive 23, and a power cable C is embedded in the adhesive 23.

  When the hollow corner column 21 as shown in FIG. 4 (A) is used, the overall structure is strong and excellent in strength, and when an object hits the corner, it prevents the impact from reaching the glass plate. Therefore, since the wiring work and the bonding work are separated, the wiring work and the bonding work can be easily performed. In addition, there is an advantage that replacement and addition of the power cable C or addition of a communication cable for sensors can be easily performed, but there is a problem that the corner column 21 is conspicuously inferior in appearance.

  On the other hand, in the configuration of FIG. 4B, it is estimated that the end face of the glass plate 22 is cut obliquely, which is caused by light diffraction, but the adhesive 23 is not so noticeable even if it is considerably thick. It has the advantage of being excellent in appearance. However, on the other hand, it is troublesome to perform the bonding operation in a state where the power cable C is embedded in the adhesive 23, and replacement and addition of the power cable C or addition of a sensor is extremely troublesome. Compared to FIG. 4A, there is a problem that the strength is inferior and the impact from the outside is also weak.

  The present invention has been made in view of such a situation, and it is an object to be able to realize the ease of wiring work and bonding work while ensuring the strength and the protective function and the appearance of the corner portion. To do.

  The display case according to the present invention includes a plurality of transparent plates surrounding the exhibition space, and two transparent plates adjacent to each other in a crossing posture are interposed between the end surfaces of the two transparent plates. The basic structure is such that one corner portion is formed by the two transparent plates.

  According to the first aspect of the present invention, in the basic configuration, the end surfaces adjacent to each other of the two crossed transparent plates cross at an obtuse angle with a wide surface whose entire width or part is directed to the exhibition space. The edge material is sandwiched between the end surfaces of the two transparent plates, and the edge material and the end surfaces of the two transparent plates are bonded to each other. It is adhered with an agent.

  According to a second aspect of the present invention, in the first aspect, a portion of the edge material exposed outside the exhibition space is curved in a convex shape outward in cross section. According to a third aspect of the present invention, in the first or second aspect of the present invention, the edge portion of the glass plate is provided with a positioning portion that partially contacts the portion exposed to the exhibition space.

  Since the present invention has a hollow portion for wiring in the edge material, the wiring work and the bonding work can be performed separately, so that the assembly work of the display case can be prevented from becoming troublesome, Cables can be easily replaced and added. Furthermore, since the edge material also functions as a support column or a frame material, it is possible to ensure a high strength as a whole display case and to have an excellent protective function when an object hits the corner portion.

  In addition, since the whole or a part of the end face of the glass plate is inclined so as to form an obtuse angle with respect to the wide surface facing the exhibition space, the edge material is utilized by utilizing a phenomenon presumed to be caused by light diffraction. Can be made inconspicuous, so it looks good.

  In particular, when the portion exposed to the outside of the edge material is formed in an arc shape as in claim 2, the edge material has a smaller exposed area than the case where the edge material is square, which is more favorable for appearance and is preferable. . Further, the prior art of FIG. 4A has a problem that the exposed portion of the column is angular, so that it is easy to be damaged when hit by an object, and damage is great when hit by a person. Adopting the configuration has an advantage that the hit area is large regardless of whether it hits an object or a person, so that it is difficult to be damaged when an object hits and damage to the person is small when it hits.

  Furthermore, if the structure of Claim 3 is employ | adopted, since a glass plate and an edge material can be positioned correctly in adhering the adjacent glass plate to an edge material, the work of assembly work can be suppressed and the finished dimensional accuracy of the display case is also improved. There is an advantage that can be improved.

  Next, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 to 3).

(1) Outline of the display case Fig. 1 (A) is a rough overall perspective view showing an example of the display case. The display case 1 of the present example has a base 2 and a top plate 3 that are square in plan view, and four rounds. A vertically long rectangular transparent front plate 4, side plate 5 and back plate 6 are provided. Accordingly, there are four corner portions around the display case 1. The front plate 4, the side plate 5, and the back plate 6 are made of glass plates having excellent transparency and strength.

  In the present embodiment, the base 2 is thin and has a small height compared to the width dimensions of the front, rear, left and right, the plates 4, 5, and 6 are fixed to the side surfaces of the base 2, and the base 2 includes An exhibition stand 7 having a smaller front-rear dimension and width dimension than the base 2 is provided. . Accordingly, although there is a space between the display stand 7 and the plates 4, 5, 6, the display stand 7 and the base 2 are integrated to each plate 4, 5, 6 from the upper end of the display stand 7. May be launched.

  1A is a cross-sectional view taken along the line B-B of FIG. 1B, and the ceiling portion of the display case 1 is arranged with a space between the top plate 3 and the display case 1 as shown in FIG. A translucent plate 8 is provided, and the translucent plate 8 is fixed to a top frame 9 made of a metal plate having a square opening in a plan view and an adhesive (caulking agent) 10. And the groove shape part 9a, 9b, 9c of downward opening is bent and formed in the four periphery of the top frame 9, and the plates 4, 5, 6 are inserted in each groove shape part 9a-9c. A lamp 11 such as a fluorescent lamp is provided in the space between the top plate 3 and the translucent plate 8.

  The front plate 4 and the left and right side plates 5 are integrally connected (fixed) by means to be described later, while the back plate 6 is a groove 9c formed on the top frame 9 and a lower rail (not shown) provided on the base 2. The article AS can be taken in and out by sliding the back plate 6 and opening the interior. Needless to say, the space above the display stand 7 of the space surrounded by the four plates 4, 5, 6 is the display space 12. The back plate 6 can be a horizontal rotation type or a detachable type.

(2). 1st Embodiment regarding joining of a front board and a side board The concrete embodiment of the joining means of the front board 4 and the side board 5 is shown in FIG.2 and FIG.3. First, description will be made in order from the first embodiment of FIG. Note that the front plate 4 and the left and right side plates 5 are joined (fixed) by the same means, but in FIGS. 2 and 3, the joining location between the front plate 4 and the right side plate 5 is representatively depicted.

  In the present embodiment, the front plate 4 and the side plate 5 are joined via the edge material 14 and the adhesive 15. In the first embodiment shown in FIG. 2 (A), the edge member 14 has a hollow rectangular shape extending long in the diagonal direction of the display case 1 in plan view, and a cable C such as a power source is passed through the inside thereof. Yes. A portion 14a of the edge member 14 exposed to the outside from between the front plate 4 and the side plate 5 is flat.

  Therefore, when the display case 1 is viewed as a whole, the corner portion constituted by the front plate 4 and the side plate 5 is chamfered. On the other hand, the two wide surfaces of the edge member 14 extend in parallel, and the wide surface of the edge member 14 is bonded to the end surface 4 a of the front plate 4 and the end surface 5 a of the side plate 5 with an adhesive (caulking agent) 15. Yes.

  The adhesive 15 is applied to the entire end surfaces 4 a and 5 b of the front plate 4 and the side plate 5. For this reason, the end surfaces 4 a and 5 a of the front plate 4 and the side plate 5 are the wide surfaces facing the exhibition space 12. An obtuse angle (135 degrees) is formed in a plan view, and an acute angle (45 degrees) is formed in a plan view with the wide surface exposed to the outside. Moreover, the end surface 4a of the adjacent front plate 4 and the end surface 5a of the side plate 5 extend in parallel. The edge member 14 can be a metal product such as an extruded product of aluminum or a extruded product of resin. In the case of metal, it is inevitably opaque, but even in the case of resin, it is preferable to use an opaque material so that the internal cable C cannot be seen. It is preferable to use a transparent adhesive 15 in terms of appearance.

  In the above configuration, since the front plate 4 and the side plate 5 are joined via the hollow edge member 14, the power cable C and various sensor cables can be wired inside the edge member 14. The assembly work of the display case 1 is not time-consuming and the cable C can be easily replaced or added without separating the plates 4 and 5. Further, the front plate 4 and the side plate 5 have an acute angle between the end surfaces 4a and 5a and the outer surface in a plan view, so that the edge material 14 is not conspicuous but looks good. . Furthermore, since the end surface 4a of the front plate 4 and the end surface 5a of the side plate 5 are cut obliquely, the area of the end surfaces 4a and 5a is larger than that in FIG. There are also advantages.

(3). Other Embodiments The second embodiment shown in FIG. 2 (B) is a modification of the first embodiment, and the difference from the first embodiment is that the surface 15a exposed to the outside is in plan view. It is curved in an outwardly convex shape, and a positioning flange portion 14b that partially hits the inner surface of the front plate 4 and the side plate 5 is formed at the end of the edge member 14 facing the exhibition space 12. It is.

  If the surface exposed to the outside of the edge member 14 is formed into an arcuate curved surface as in the second embodiment, it seems to be due to the illusion of human eyes, but it appears to be thinner than the actual width and looks better. Are better. Further, since the front and rear positions and the left and right positions of the front plate 4 and the side plate 5 are regulated by the flange portion 14b of the edge material 14, the positional relationship between the three of the front plate 4 and the side plate 5 and the edge material 14 is accurately regulated. As a result, it is possible to contribute to improving the efficiency and accuracy of assembly work.

  In the third embodiment shown in FIG. 2 (C), the edge member 14 has a fan-shaped hollow section 14c positioned near the outside and a plate-shaped section 14d positioned near the exhibition space 12, or a substantially fan-shaped fan in plan view. It has a ginkgo leaf shape. The adhesive 15 has the same thickness as a whole. Therefore, the end surfaces 4a and 5a of the front plate 4 and the side plate 5 are flat on the portions 4a 'and 5a' facing the plate-like portion 14d of the edge member 14. Crossing is performed at an obtuse angle (about 135 degrees) in a cross-sectional view, and the portions 4a "and 5a" facing the hollow portion 14c of the edge member 14 cross at an angle of 90 degrees with the outer surface in a plan view.

  In the fourth embodiment shown in FIG. 2 (D), the edge member 14 is formed in a U-shaped groove shape (a bowl shape) that is open toward the exhibition space 12 and has an opening in the edge member 14. The cap 16 is detachably mounted from the direction of the exhibition space 12. The cap 16 has a foot portion 16 a that fits inside the edge member 14. If the edge member 14 is formed in a groove shape as in the fourth embodiment, there is an advantage that the wiring work (particularly, the wiring work after assembly) can be performed more easily.

  The fifth embodiment shown in FIG. 3A is a modification of the second embodiment, and the difference from the second embodiment is that the edge surface 14 of the front plate 4 and the end surface 5a of the side plate 5 of the edge member 14 are different. A concave groove 17 is formed on the wide surface opposite to the concave groove 17 and the concave groove 17 is filled with an adhesive 15. In this embodiment, since the edge member 14 and the front plate 4 and the side plate 5 can be tightly adhered to each other, there is an advantage that the front plate 4 and the side plate 5 and the edge member 14 can be more accurately aligned.

  The sixth embodiment shown in FIG. 3 (B) is a modification of the first embodiment. In this embodiment, the edge member 14 is tapered in a plan view so that the lateral width becomes narrower as it goes outward from the exhibition space 12 (copper cup). Shape). Accordingly, the distance between the end surface 3a of the front plate 4 and the end surface 5a of the side plate 5 becomes narrower from the display space 12 toward the outside.

  In the seventh embodiment shown in FIG. 3 (C), the width of the edge member 14 increases from the display space 12 to the outside, contrary to the sixth embodiment, and a positioning flange is provided at the base end. A portion 14b is formed.

(4). Others The present invention can be embodied in various ways other than the above embodiment. For example, in the case of a display case having a square shape in plan view, it is possible to form a cylindrical rigid body as a whole by joining four transparent plates in series. In the case of an exhibition case installed near a wall, the back plate can be made of an opaque material such as a plywood or a metal plate. Furthermore, the present invention can be applied to display cases such as triangles and pentagons in plan view.
