Description

  The present invention relates to a packing apparatus that packs a thin plate such as a glass plate in a vertically leaning state.

  In recent years, there is a growing need for an increase in the size of glass plates used for glass for liquid crystal displays. When packing and transporting such a large glass plate, if a plurality of glass plates are stacked horizontally and packed, the loading weight of the upper glass plate is added to the lower glass plate in the stacked state. Since the lower glass plate may be damaged, there is a problem that the number of glass plates to be packed is limited. Therefore, conventionally, when packing and transporting a glass plate which is a kind of such a thin plate, a packing device for packing a plurality of glass plates in a vertically leaning state is used (for example, Patent Document 1).

The glass plate package (packing device) described in Patent Document 1 has a pallet (supporting member) that is substantially L-shaped in a side view and includes a bottom wall portion and a back wall portion. The top surface of the bottom wall portion of the pallet is used as a mounting surface portion (mounting portion) for mounting the lower end edges of a plurality of glass plates, and the front surface of the back side wall portion of the pallet is stacked against each other. It is set as the standing surface part (leaning part) to be made.

  By the way, when transporting a glass plate package in a supporting state in which a glass plate is placed on a pallet, such a glass plate package is usually transported in a state of being loaded on a loading platform of a vehicle such as a truck. There are many cases. In such a case, it is desirable to suppress the vibration of the vehicle due to the unevenness of the road surface on which the vehicle such as a truck travels from being transmitted to the glass plate via the pallet. Moreover, in order to improve the handleability etc. of the packing apparatus at the time of packing of a glass plate and at the time of conveyance, the weight reduction of the glass plate package including a pallet is also desired. Therefore, in the past, in order to ensure the durability, the glass plate package is often made of a rigid material such as a metal material, but recently, the cardboard paper is lightweight and cushioning. The glass plate package which comprised the pallet etc. is used.

  However, in the glass plate package described in Patent Document 1, for example, when the pallet is made of corrugated paper, the upper surface of the bottom wall portion of the pallet may be depressed downward under the load of the glass plate. is there. And in the intrusion site | part, when the lower end edge of a glass plate bites in, a corrugated paper will be compressed and a buffer function will be inhibited. In particular, when the glass plate is supported on the pallet in a leaning state, the load on the glass plate acts locally on the upper surface of the bottom wall portion of the pallet, and this phenomenon is remarkable. It becomes.

  Therefore, in such a glass plate package, in the packaging state of the glass plate, it becomes impossible to ensure buffering properties against the glass plate, and when the glass plate is taken out from the pallet, the lower edge of the glass plate is formed on the bottom wall portion of the pallet. There is a risk that it will be difficult to perform the removal work by biting into the indented site. In addition, since corrugated paper is a material having low restoring force, once an indented portion is formed on the upper surface of the bottom wall portion of the pallet, the glass plate package is repeated while ensuring buffering properties against the glass plate. There was also a problem that it was difficult to use.

  The present invention has been made in view of such circumstances. The purpose of the present invention is to provide cushioning to the thin plate in the packing state and work at the time of removal when the thin plate is packed in a vertically leaning state. An object of the present invention is to provide a packaging device that can be used repeatedly while ensuring the ease of the above.

  In order to achieve the above object, the packing device of the present invention has a support member that can support at least one thin plate in a vertically placed leaning state, and the thin plate is supported on the support member. The thin plate can be packed together with the support member, wherein the support member has a placement portion on which the lower end edge of the thin plate can be placed, and a lower end edge of the thin plate on the placement portion. And a leaning portion capable of leaning the back surface of the thin plate when placed, and at least the placement portion is made of corrugated paper, and on the placement portion, the thin plate A shock-absorbing member is provided that is elastically deformed when a load is received, and is restored to its original shape when the load on the thin plate is eliminated in the elastically deformed state.

  According to the above configuration, since at least the placement portion of the support member is made of cardboard, the weight can be reduced accordingly. And when the lower end edge of a thin plate is mounted on the mounting part, the load of a thin plate will act on a mounting part in the state relieved by the elastic deformation of the buffer member. Therefore, it is avoided that the load of a thin plate acts locally with respect to the mounting part of a support member, and it is suppressed that the mounting part of a support member receives a load of a thin plate, and intrudes below. That is, the intrusion site where the lower edge of the thin plate is bitten is not formed on the mounting portion of the support member. In addition, when the thin plate is taken out from the support member, the buffer member is restored to the shape before elastic deformation because the load of the thin plate that has been applied until then is eliminated. Therefore, when packing a thin plate in a vertically leaning state, the thin plate can be repeatedly used while guaranteeing buffering properties for the thin plate in the packed state and ease of work at the time of taking out.

Moreover, in the packing apparatus of the present invention, the placement unit is formed in a block shape by superposing a plurality of corrugated paper sheets in a vertically arranged state.
According to the above configuration, the mounting portion of the support member has a block shape in which a plurality of cardboard sheets are superposed in a vertically arranged state. The end face of each corrugated cardboard in a superposed state receives the load of the thin plate applied through the joint. Therefore, it is possible to improve the resistance of the mounting portion with respect to the load of the thin plate, and it is possible to suppress deformation of the mounting portion of the support member due to the load of the thin plate in the packaged state.

  In the packing device of the present invention, the leaning portion has a leaning surface that faces the back surface of the thin plate when the lower edge of the thin plate is placed on the mounting portion. The leaning surface is formed so that the upper end side thereof is inclined and positioned on the far side in the leaning direction of the thin plate than the lower end side.

  According to the above configuration, the thin plate is inclined with respect to the leaning surface of the leaning portion in the state where the lower edge thereof is placed on the placing portion of the support member via the buffer member. It is leaning on condition. Therefore, as compared with the case where the thin plate is packed in a leaning state along the vertical direction, the thin plate can be packed in a state where it is easily and stably leaned against the leaning portion. become.

In the packing device of the present invention, the leaning portion is formed in a prismatic shape by folding at least one cardboard paper through a plurality of folding lines.
According to the above configuration, since the support member is also made of corrugated cardboard in addition to the placement portion, the weight can be further reduced and the lean portion Is a structure in which corrugated cardboard is bent so as to form a prismatic shape via a plurality of folding lines, so that the rigidity of the leaned thin plate can be secured.

Moreover, the packing apparatus of this invention has at least one pair of the said supporting members, and the supporting members which make a pair mutually are arrange | positioned so that both leaning parts may be in a backrest state mutually.
According to the above configuration, when the thin plate is supported in a leaning state on the support members that are paired with each other, loads in opposite directions are applied to the leaning portions of the support members. Therefore, each support member can maintain the state which leaned the thin plate stably by canceling those loads. In addition, since the thin plate can be supported on each support member in two different directions, an improvement in work efficiency at the time of packing and taking out the thin plate can be expected.

Moreover, the packing apparatus of this invention WHEREIN: As for the said support member, the above-mentioned mounting part is comprised with the reinforced corrugated cardboard.
According to the above configuration, since the mounting portion of the support member is made of reinforced corrugated paper having excellent load resistance, the mounting portion of the support member is prevented from being deformed by the load of the thin plate in the packaged state. it can.

Moreover, the packing apparatus of this invention WHEREIN: The said thin plate is a glass plate.
According to the said structure, a glass plate with low impact resistance can be packed suitably by utilizing the packing apparatus of this invention.

  In addition, a partition wall 27 that divides the space in the housing 13 into two front and rear chambers is provided at a substantially central portion in the front-rear direction on the upper surface of the underlay 24. The partition wall 27 is constituted by a partition member 28 made of a pair of corrugated cardboards having a U-shape in plan view, and the partition members 28 are arranged so as to be in a back-to-back state. It should be noted that corrugated cardboard angles 29 having an L-shaped cross section are respectively disposed at the left and right corners of each partition member 28.

  In addition, a plurality of support members 25 (a total of four support members 25 in the present embodiment, each paired on the front side and the rear side) for supporting the glass plate 18 are provided in front and rear of the partition wall 27 on the upper surface of the underlay 24. Each is placed. Since each support member 25 has the same configuration, the front support member 25 disposed in front of the partition wall 27 will be described below for convenience of understanding the description. The redundant description of the rear support member 25 disposed behind 27 is omitted.

  A plurality of (two in this embodiment) front support members 25 are arranged in parallel along the left-right direction. Each support member 25 is bonded to a column 30 in which a plurality of columns 30a having a substantially square column shape are arranged in parallel in the left-right direction (two in this embodiment), and to both left and right side surfaces of the column 30 via an adhesive. And a pair of armrests 31 having a substantially L shape in side view. And the glass plate 18 arranged in parallel so that the back side is leaned on the support column 30 in a state where the lower end edge is placed on the armrest portion 31, from both the front and rear sides by a pair of protective plates 32 having a flat plate shape. It is supported on the support member 25 in a sandwiched state. In addition, between the glass plates 18 adjacent to each other in the leaning direction, in order to prevent the glass plates 18 from being in frictional contact with each other during the transporting process of the glass plates 18 and causing scratches, crushed wood pulp and waste paper are used. A glass interleaving sheet (not shown) or a protective sheet made of synthetic resin (not shown) is interposed.

  At this time, each armrest portion 31 functions as a placement portion on which the lower end edge of the glass plate 18 can be placed, and the column portion 30 has the lower end edge of the glass plate 18 placed on the upper surface of the armrest portion 31. In this case, it functions as a leaning portion that can lean the back surface of the glass plate 18. In addition, the space | gap is formed in the left-right direction between each armrest part 31, and the freedom degree of the structure of the packaging apparatus 11 is raised by utilizing this space | gap suitably (for example, arrange | positioning a desiccant etc.). .

  Further, the front corner of the protection plate 32 of the glass plate 18 disposed in front of the partition wall 27 and the rear corner of the protection plate 32 of the glass plate 18 disposed behind the partition wall 27 have a cross section L. Angles 33 and 34 made of corrugated cardboard having a letter shape are arranged. Then, a long band 36 (see FIG. 8) is inserted into the insertion holes 35 formed in the respective angles 33 and 34, and the glass plate 18 is closely attached to the support member 25 by being secured in the lateral direction. It is possible to support it stably.

  Further, around the support member 25, a front lid 15 having a U-shape in plan view is attached along the edge of the lower lid 14 so as to close the opening on the front side of the partition wall 27, and the partition wall A rear lid 16 having a U-shape in plan view is attached along the edge of the lower lid 14 so as to close the opening on the rear side.

As a result, the packing device 11 can pack the glass plate 18 in a state of leaning on the support member 25 in a vertical position. A pressing member (not shown) is interposed between the glass plate 18 and the front lid 15 and between the glass plate 18 and the rear lid 16 so as to fill these gaps in the front-rear direction. The pressing member restricts the glass plate 18 from being displaced in the front-rear direction in the packing device 11.

Next, the structure of the support member 25 which is the main part of the present invention will be described with reference to FIGS.
As shown in FIGS. 3 to 5, each column 30 a constituting the column 30 of the support member 25 is formed into a hollow square column by bending a substantially trapezoidal plate member 37 made of corrugated paper. It is formed. Specifically, when the plate member 37 is bent as the support column 30a, the front side surface portion 38 constituting the front surface, the rear side surface portions 39 and 40 constituting the rear surface, and the left surface of the side surfaces of the support column 30a. The left side surface part 41 which comprises, and the right side surface part 42 which comprises a right surface are provided. And these side surface parts 38-42 are connected continuously via the multiple (four in this embodiment) broken line 43a, 43b, 43c, 43d formed along the longitudinal direction of the plate member 37. As shown in FIG.

  A fitting groove 44 is cut out at the center of the lower end edge of the front side surface 38, and the front side surface is widened downward from the lower end edges of the left side surface portion 41 and the right side surface portion 42. The bottom surface portions 45 and 46 each having a substantially trapezoidal shape in which the side sides 45a and 46a on the side of the portion 38 are inclined inwardly extend. The bottom surface portions 45 and 46 are further bent at right angles via folding lines 47a and 47b that bisect the bottom surface portions 45 and 46 when the support member 30a is bent from the plate member 37, and the left side surface portion 41 is further bent. Further, the side sides 45a and 46a on the front side surface 38 side of the bottom surface portions 45 and 46 are fitted into the fitting grooves 44 by being bent inward from the lower end edge of the right side surface portion 42 ( (See FIG. 5).

  Further, a plurality of (two in this embodiment) support claws 48 project from the side edge along the longitudinal direction of the rear side surface portion 39, and at positions corresponding to the respective support claws 48 on the broken line 43d. A locking hole 49 is formed. Then, the plate member 37 is assembled so as to form a quadrangular prism shape by pasting the rear side surface portions 39 and 40 in a state where the support claws 48 are inserted into the locking holes 49. The front side surface portion 38 and the rear side surface portions 39 and 40 are formed to have a rectangular shape, and the left side surface portion 41 and the right side surface portion 42 are formed to have a substantially trapezoidal shape that becomes narrower toward the upper end side. Has been.

  When the plate member 37 is assembled as the support column 30a by bending it at each of the broken lines 43a, 43b, 43c, 43d, the front side surface portion 38 has an inclined surface shape in which the upper end side is located rearward than the lower end side. Is formed. That is, the front side surface portion 38 as the leaning surface of the glass plate 18 is formed so that the upper end side is inclined from the near side in the leaning direction of the glass plate 18 to the far side. Further, protrusions 50a and 50b are formed on the lower end edges of the rear side surface parts 39 and 40, respectively, and when the column 30a is bent from the plate member 37, these protrusions 50a and 50b are overlapped with each other. The bottom portions 45 and 46 are configured to project downward from the rear end edges.

  Here, among the members made of corrugated paper constituting the packing device 11, in particular, the armrest portion 31 that receives the load of the glass plate 18 is composed of reinforced corrugated paper, and the other members are composed of ordinary corrugated paper. ing. Note that reinforced corrugated paper is variously processed for the purpose of increasing the strength of ordinary corrugated paper (for example, processing of a multilayer structure such as a two-layer structure or a three-layer structure; This refers to those that have been subjected to processing such as the use of virgin pulp having a long fiber.

  As shown in FIGS. 3 and 6, the armrest portion 31 of the support member 25 has a plurality of (six in this embodiment) reinforced corrugated paper sheets bonded to each other via an adhesive. Thus, it is formed so as to form a block shape that is superposed in a state of being arranged in parallel in the vertical direction. And the armrest part 31 is provided with the connection part 51 connected with the base end part of the right-and-left both sides | surfaces of the support | pillar part 30, and the substantially rectangular parallelepiped base part 52 extended ahead using this connection part 51 as a base end. Yes.

  The connecting portion 51 is formed so that the front surface 51 a forms an inclined surface having the same inclination angle as the front side surface portion 38 of each column 30 a constituting the column 30, and supports the back surface of the glass plate 18. Function as. The front surface 51a of the connecting portion 51 is covered with a piece of corrugated paper to ensure flatness. As a result, the armrest portion 31 supports the back surface of the glass plate 18 evenly in cooperation with the front side surface portion 38 of each support column 30a in which the front surface 51a of the connecting portion 51 constitutes the support column portion 30 over the entire surface, and stably glass. The plate 18 can be arranged vertically.

  The base 52 has a flat surface by ensuring that the upper surface 52a is covered with a piece of corrugated paper. As a result, the upper surface 52a of the base portion 52 can make the rubber member 53 stably contacted with an adhesive by bringing the flat rubber member 53 into contact with the entire surface. And when the upper surface 53a which functions as a mounting surface of the glass plate 18 receives the load of the glass plate 18, the rubber member 53 elastically deforms and absorbs the load so that the load of the glass plate 18 is made of cardboard. It functions as a buffer member that buffers the direct application to the upper surface 52a of the base 52.

  On the other hand, the rubber member 53 is restored to its original shape when the load on the glass plate 18 is eliminated by removing the glass plate 18 from the upper surface 53a in the elastically deformed state. A projecting portion 54 having a rectangular plate shape projecting downward is formed at an intermediate position in the front-rear direction on the lower surface of the base portion 52. Further, a locking portion 55 having a substantially semicircular shape in side view protruding upward is formed on the distal end side of the base portion 52, and the locking member 55 is configured such that the rubber member 53 is displaced in the front-rear direction. Is regulated.

  As shown in FIG. 7, when the support member 25 is assembled to the underlay 24, the projection 54 and the plan view are omitted in a position corresponding to the projection 54 formed on the lower surface of the base 52 of the armrest portion 31. Long holes 26a and 26b having the same shape are formed. The underlay 24 is a plane having the same width as the protrusions 50a and 50b at positions corresponding to the protrusions 50a and 50b formed on the lower surface of each support 30a of the support 30 when the support member 25 is assembled. A long hole 26c having a rectangular shape is formed.

  And among the support members 25 which make a pair in the front-rear direction, the protrusion 54 of the armrest portion 31 of the support member 25 arranged on the front side is fitted into the elongated hole 26a, and the support member 25 arranged on the rear side of the support member 25 The protrusion 54 of the armrest portion 31 is inserted into the long hole 26b. In addition, the protrusions 50a and 50b of the support columns 30 of the support members 25 that are paired in the front-rear direction are fitted into the elongated holes 26c. As a result, the support members 25 that are paired with each other are positioned and fixed so as not to be relatively movable in the horizontal direction with respect to the underlay 24 in an arrangement mode in which both support portions 30 are in a backrest state.

Next, the effect | action of the packing apparatus 11 mentioned above is demonstrated, referring FIG.8 and FIG.9.
Now, in the packing device 11, when packing the glass plate 18 in a vertically leaning state, the lower end edge of the glass plate 18 is placed on the armrest portion 31 of the support member 25 and the back surface of the glass plate 18. In the state where it is leaned on the support column 30, the periphery thereof is secured with a band 36 (see FIG. 8).

  Here, when the armrest portion 31 is made of corrugated paper, the cardboard paper is made of a material having low rigidity compared to metal or the like, so that the load of the glass plate 18 is locally applied to the upper surface 52 a of the base portion 52 constituting the armrest portion 31. There is a possibility that the armrest portion 31 is greatly compressed and deformed by acting on the surface. In this regard, in the packing device 11 of the present embodiment, the rubber member 53 is disposed on the upper surface 52a of the base portion 52 of the armrest portion 31. Therefore, when the glass plate 18 is placed on the armrest portion 31, the rubber member 53 prevents the armrest portion 31 from compressing and deforming according to the load as follows.

  That is, when the glass plate 18 is leaned at a predetermined angle with respect to the vertical direction, the load of the glass plate 18 acts on the corner on the front side in the tilt direction on the lower end surface of the glass plate 18. The part corresponding to the corner | angular part of the glass plate 18 in the upper surface 53a of the rubber member 53 invades locally (refer FIG. 9). The upper surface 53a of the rubber member 53 is wavy in the front-rear direction so as to correspond to the inclination angle of the lower end surface of the glass plate 18, so that the glass plate is in contact with the entire lower end surface of the glass plate 18. 18 is supported. As a result, the load of the glass plate 18 acts in a state of being distributed over the entire upper surface 53a of the rubber member 53 through the entire lower end surface of the glass plate 18, and further, the dispersed load is applied to the upper surface of the base 52 of the armrest portion 31. It acts equally over the entire area 52a.

  In other words, even when the glass plate 18 is vertically arranged in parallel on the upper surface 53a of the rubber member 53, the armrest portion 31 is locally greatly compressed and deformed by dispersing and buffering the load of the glass plate 18. Suppress. Therefore, when the glass plate 18 is taken out from the armrest portion 31, the lower end edge of the glass plate 18 is not caught in the upper surface 52 a of the base portion 52 of the armrest portion 31. It is possible to ensure the ease of

  In addition, when the load of the glass plate 18 which acts on the upper surface 52a of the base 52 of the armrest part 31 with the removal of the glass plate 18 is eliminated, the rubber member 53 has a shape substantially before deformation according to the restoring force of the rubber. To be restored. That is, the rubber member 53 has a thickness necessary for buffering the load of the glass plate 18 and restores a flat plate shape in which the upper surface 53a on which the lower end edge of the glass plate 18 is placed forms a smooth plane. As a result, the armrest portion 31 can be used repeatedly while ensuring buffering properties against the glass plate 18 when the glass plate 18 is placed in a vertically leaning state.

According to the present embodiment, the following effects can be obtained.
(1) In the said embodiment, since the armrest part 31 is comprised with the corrugated paper at least, the support member 25 can achieve weight reduction by that much. And when the lower end edge of the glass plate 18 is mounted on the armrest part 31, the load of the glass plate 18 will act on the armrest part 31 in the state relieved by the elastic deformation of the rubber member 53. . Therefore, it is avoided that the load of the glass plate 18 acts locally with respect to the armrest part 31, and it is suppressed that the armrest part 31 receives the load of the glass plate 18, and intrudes below. That is, the armrest portion 31 is not formed with an invaginated portion where the lower end edge of the glass plate 18 is bitten. Further, when the glass plate 18 is taken out from the armrest portion 31, the rubber member 53 is restored to the shape before elastic deformation because the load of the glass plate 18 that has been applied so far is eliminated. Therefore, when packing the glass plate 18 in a vertically leaning state, the glass plate 18 can be repeatedly used while guaranteeing the buffering property for the glass plate 18 in the packing state and the ease of work at the time of taking out. Become.

  (2) In the above embodiment, the armrest portion 31 has a block shape in which a plurality of corrugated cardboard sheets are superposed in a vertically arranged state, so that the armrest portion 31 is interposed via the rubber member 53. The end face of each corrugated cardboard in a superposed state receives the load of the glass plate 18 applied in this manner. Therefore, the resistance of the armrest portion 31 with respect to the load of the glass plate 18 can be improved, and deformation of the armrest portion 31 due to the load of the glass plate 18 in the packed state can be suppressed. In particular, since the armrest portion 31 is made of reinforced corrugated cardboard having a higher strength than ordinary corrugated cardboard, deformation due to the load of the glass plate 18 can be effectively suppressed.

  (3) In the above embodiment, the glass plate 18 is inclined with respect to the front side surface 38 of the support column 30 with its lower end edge placed on the armrest 31 via the rubber member 53. It is leaned in the state. Therefore, as compared with the case where the glass plate 18 is laid in a leaning state along the vertical direction, the glass plate 18 is packed in a state where the glass plate 18 is easily and stably leaned against the support column 30. Will be able to.

  (4) In the above embodiment, since the support member 25 is made of corrugated paper in addition to the armrest portion 31, the weight can be further reduced. Moreover, since the support | pillar part 30 is the structure which arrange | positioned the support | pillar 30a bent so that corrugated paper may make the prismatic shape via several broken lines 43a-43d, the rigidity with respect to the leaned glass plate 18 is also ensured. it can.

  (5) In the above embodiment, when the glass plate 18 is supported in a leaning state on the support members 25 that are paired with each other, loads in opposite directions are applied to the support columns 30 of the support members 25. . Therefore, each support member 25 can maintain the state which leaned the glass plate 18 stably by canceling those loads.

It is desirable that the rear side surface portions 39, 40) of the support columns 30a are formed so that the lower end side has an inclined surface located on the far side in the leaning direction of the glass plate 18 than the upper end side. According to this configuration, even if the support column 25 in the support member 25 is in an arrangement configuration in which the support column 30 in the other support member 25 is not backrested with respect to each other, the surface opposite to the leaning surface is glass. Since the function of replacing the leaning surface of the plate 18 that receives the leaning load is fulfilled, the column portion 30 of the support member 25 can be erected stably.

  -In the said embodiment, as shown in FIG.10 and FIG.11, you may form the armrest part 31 of the supporting member 25 so that the upper surface of the base 52 may make an inclined surface with respect to a horizontal direction. That is, the upper surface of the base portion 52 may be formed so as to have an inclined surface shape in which the near side in the leaning direction of the glass plate 18 is positioned above the far side. In this case, the rubber member 53 placed on the upper surface of the base 52 is similarly inclined with respect to the horizontal direction. When the glass plate 18 is placed on the rubber member 53, the glass plate 18 hangs toward the front side surface 38 of the support column 30 according to the inclination angle of the upper surface of the rubber member 53. Therefore, according to this configuration, the support member 25 can more securely support the glass plate 18 by being in closer contact with the glass plate 18 more reliably. Further, it is essential to provide a locking portion 55 for restricting the positional deviation of the rubber member 53 in the front-rear direction on the distal end side of the base portion 52 of the armrest portion 31 (the front side in the leaning direction of the glass plate 18). Is not.

In the above embodiment, the support column 25 of the support member 25 may be configured by a single support 30a.
In the above embodiment, the support column 30a may have a configuration in which a plurality of cardboard papers (normal cardboard paper or reinforced cardboard paper) are bonded together. In this case, it is desirable that the corrugated cardboards are bonded so that the direction perpendicular to the leaning direction of the glass plate 18 is the polymerization direction.

  -In the said embodiment, as for each member made from corrugated paper which comprises the packing apparatus 11, all the members including the armrest part 31 may be comprised by the reinforced corrugated paper, or those members are all normal cardboard paper. It may be constituted by. Further, only the support member 25 (armrest portion 31 and column portion 30) serving as a member that receives the load of the glass plate 18 is made of reinforced cardboard, and the other members are made of ordinary cardboard. Good.

-In the said embodiment, the structure of the support | pillar 30a is not limited to prismatic shape, You may comprise so that a columnar shape or a pyramid shape may be made.
In the above embodiment, the front side surface portion 38 of the support column 30a may be formed so as to form a vertical surface orthogonal to the leaning direction of the glass plate 18.

In the above embodiment, the armrest portion 31 of the support member 25 may be formed in a block shape by superposing a plurality of corrugated cardboard sheets in a horizontally arranged state.
-In the said embodiment, the buffer member arrange | positioned on the armrest part 31 is not limited to the rubber member 53, Other members are applicable if it is a member which has the buffer property with respect to the load of the glass plate 18, and a restoring force.
