JP-A-9-32354 (FIGS. 4, 5, and 9) JP 2010-287500 A (FIGS. 1 and 2)

  As described above, in the conventional technology, the shaft member is supported at one point at the upper end of the shaft member. Therefore, if the inner diameter of the concave portion is slightly increased with respect to the outer diameter of the shaft member, the rotating body may be staggered during rotation. In some cases, the lower end portion of the rotating body collides with the shaft member or the base to cause chipping or cracking. In addition, it is necessary to accurately drill the recess in the rotated body corresponding to the shaft member, and if the position of the recess deviates from the desired position, it is impossible to correct it. Therefore, the range of application of the above prior art is limited to a rotated body that can relatively easily find the position of the center of gravity and that can accurately drill the recess at the center of the bottom surface corresponding to the position of the center of gravity. And lacked versatility. For example, in the stone lantern described in Patent Document 2, a candle stand is arranged inside a hollow stone material provided with an opening on the front surface. However, the above conventional technology is not applied to a stone lantern using such a hollow stone material. Could not be applied.

  The present invention has been made in view of the above problems, and can provide a rotation support device that can stably rotate a rotating body formed of a stone pillar or a hollow stone material, and has excellent versatility, and the rotation support device. The purpose is to provide the stone lanterns used.

  A first aspect of a rotation support device according to the present invention is a rotation support device that rotatably supports a rotating body formed of a stone pillar or a hollow stone material with respect to a foundation such as a base or a ground, and has the above object. To achieve this, a shaft member whose lower end is fixed to the foundation and whose center and upper end protrude upward from the foundation, a flat plate central portion is fixed to the central portion of the shaft member, and a flat plate periphery is a flat plate center A first flat plate extending in a horizontal direction from the portion, and an upper surface that supports the rotating body, and the lower surface is pivotally supported with respect to the upper end of the shaft member in a state of facing the upper surface of the first flat plate in parallel. A second flat plate and three or more spheres sandwiched between the first flat plate and the second flat plate, and in one of the first flat plate and the second flat plate, a recess is formed on a surface facing the other flat plate. Is formed, and the sphere is accommodated in a rollable manner.

  In the rotation support device configured as described above, the center portion and the upper end portion of the shaft member protrude upward from the foundation in a state where the lower end portion of the shaft member is fixed to the foundation such as the base or the ground. The first flat plate is fixed to the central portion of the shaft member, three or more spheres are disposed on the upper surface of the first flat plate, and the second flat plate is disposed on the upper end of the shaft member. It is rotatably supported with respect to the part. And these spheres can roll in the recessed part provided in the 1st flat plate or the 2nd flat plate. Therefore, the processed object is supported by the upper surface of the second flat plate without any processing on the rotated object, and even if the rotated object is a stone pillar as well as a hollow stone material. The two flat plates rotate smoothly around the shaft member. Further, when the center of gravity of the rotated body is not positioned above the shaft member, the rotation of the rotated body becomes unstable. In this case, the second center is set so that the center of gravity of the rotated body is positioned above the shaft member. It is possible to easily stabilize the rotation by adjusting the position of the rotated body on the flat plate. Furthermore, the rotating body is rotated by rolling the sphere between the first flat plate and the second flat plate so that the foundation and the rotating body do not collide or rub against each other. None of these rub against the rotating support device, and dust can be prevented from being generated from the foundation or the rotated body.

  A second aspect of the rotation support device according to the present invention is a rotation support device that rotatably supports a rotating body formed of a stone pillar or a hollow stone material with respect to a base such as a base or a ground, and has the above object. In order to achieve this, a first flat plate whose lower surface is fixed to the upper surface of the foundation, a shaft member whose lower end is fixed to the center of the upper surface of the first flat plate and whose upper end extends upward, and a rotated body are provided. A second flat plate rotatably supported with respect to an upper end portion of the shaft member in a state of having an upper surface to be supported and having the lower surface facing the upper surface of the first flat plate in parallel, and a first flat plate and a second flat plate It comprises three or more spheres to be sandwiched, and one of the first flat plate and the second flat plate has a recess formed on the surface facing the other flat plate, and accommodates the sphere so that it can roll. It is said.

  The rotation support device according to the second aspect is a first aspect in which the first flat plate is fixed to the shaft member fixed to the foundation in that the shaft member is fixed to the first flat plate fixed to the foundation. However, the other basic configuration is exactly the same as the first mode. That is, three or more spheres are arranged on the upper surface of the first flat plate, and the second flat plate is rotatably supported on these spheres with respect to the upper end portion of the shaft member. It can roll in a recess provided in the first flat plate or the second flat plate. Therefore, the same effect as the first aspect can be obtained.

  Here, the number of recesses and the like is arbitrary, but for example, a plurality of recesses may be provided so as to surround the shaft member. When the same number as the spheres is provided, the spheres may be accommodated one by one in the plurality of recesses. . Since the second flat plate and the rotated body are supported by the spheres accommodated in the recesses provided so as to surround the shaft member in this way, the stress is dispersed and the rotated body rotates smoothly and stably for a long time. Can be made.

  In order to achieve the above object, a stone lantern according to the present invention has a stone base, a hollow stone material provided with a first opening on the front surface and a second opening on the rear surface, and the rotation described above. It has the same structure as the support device, and includes a rotation support part that rotatably supports the hollow stone material with respect to the stone base, and a candle support part that supports the candle inside the hollow stone material. The hollow stone material is supported on the upper surface of the second flat plate, and the candle support portion is provided at the upper end portion of the shaft member.

  In the stone lantern configured as described above, a hollow stone material is used, but the hollow stone material can be rotated around the shaft member with respect to the foundation. Therefore, when the hollow stone material is rotated and positioned so that the second opening portion faces the front, the hollow interior of the hollow stone material can be accessed from the second opening portion, and the candle can be attached to the candle stand and ignited. In addition, when the hollow stone is rotated and positioned so that the first opening faces the front, a candle light is led through the first opening. Thus, the candle can be ignited smoothly by the rotation of the hollow stone.

  It is to be noted that there is further provided a reflector arranged on the back of the candle supported by the candle support part for reflecting the light from the candle to the front, and the first opening has a lattice-like part that partially covers the first opening The lower end of the reflector is fixed to the upper end of the shaft member or the candle support so that the reflector opens the second opening when the hollow stone is rotated and the first opening is positioned in front. You may comprise. In this case, the reflecting plate has a function of reflecting light from the candle to the front and a function of blocking the second opening and making the candle difficult to disappear. In addition, by providing the grid-like portion, it is possible to prevent the user from touching the candle fire through the first opening while ensuring visibility.

  Further, in addition to providing the lattice-like portion or instead of providing the lattice-like portion, a transparent member may be attached to the hollow stone material so as to close the first opening, thereby ensuring the visibility while ensuring the visibility. Can be prevented from coming into contact with the candle through the first opening, and the candle can be prevented from extinguishing due to wind entering from the first opening.

The numbers in parentheses in FIG. 3 show an example of the assembly procedure.

  The rotation support portion 5 is roughly divided into a shaft member 51, a wing member 52 attached to the lower end surface of the shaft member 51, a first flat plate 53 having a through hole 531 in a flat plate central portion, and a through hole 541 in a flat plate central portion. And a plurality of (six in this embodiment) metal or ceramic spheres 55. And it assembles by the following procedures (1)-(8). Hereinafter, the assembly procedure will be described together with the configuration of each part of the apparatus. Needless to say, this assembling procedure is an example, and the order may be appropriately changed or performed in parallel.

  (1) Of the elements constituting the rotation support portion 5, the shaft member 51 is integrated with the shaft piece 512 connected to the upper end of the shaft piece 511, and extends in the axial direction X. In the shaft member 51 configured as described above, the lower end portion and the upper end portion of the shaft piece 511 correspond to the “lower end portion of the shaft member” and the “center portion of the shaft member” of the present invention, respectively. The upper end portion corresponds to the “upper end portion of the shaft member” of the present invention. A flange member is attached to the upper end of the shaft piece 511 among these shaft pieces. Then, when the through hole 531 of the first flat plate 53 is externally fitted from the lower end portion of the shaft piece 511, the flat plate center portion of the first flat plate 53, that is, the upper surface of the peripheral portion of the through hole 531 is locked to the flange member, The first flat plate 53 is fixed to the shaft piece 511 by welding the locking portion, for example, spot welding. Further, in the first flat plate 53, a flat plate peripheral portion extends in the horizontal direction from the central portion of the flat plate, and the upper surface of the flat plate peripheral portion is a second flat plate 44 that is pivotally supported by the shaft member 51 as described later. The sphere 55 can be sandwiched between the lower surface and the lower surface.

  (2) On the lower end face of the shaft piece 511, a screw hole is provided in the axial direction X, and a female screw is screwed into the screw hole. And the wing | blade member 52 by which the wing | blade extended radially in four directions within the horizontal surface is provided.

  (6) A screw hole is provided in the axial direction X on the upper end surface of the shaft member 51, that is, the tip surface of the shaft piece 512, and a female screw is screwed into the screw hole. Then, the screw 92 is inserted into a through hole (not shown) provided in the center of the bottom surface of the candle stand receiving portion 71, and the screw 92 is fastened to the screw hole of the shaft piece 512, thereby the upper end of the shaft member 51. The candle stand receiving portion 71 is fixed to the portion. Further, it is possible to prevent the second flat plate 54 from coming off the shaft member 51 by this screw fastening process. The candle holder 72 is detachably attached to the candle holder 71. In this embodiment, the candle holder 7 is composed of the candle holder 71 and the candle holder 72. Of course, instead of providing the candle stand receiving portion 71, the candle stand 72 may be directly fixed to the upper end portion of the shaft member 51.

  In the present embodiment, as shown in FIG. 3, the reflector 10 is attached to the candle stand receiving portion 71. That is, the reflecting plate 10 is formed by bending a single metal plate and is arranged so as to surround the candle 6 standing on the candle stand 72 from the back side (the upper side in the lower diagram in FIG. 1). In this state, it is fixed to the shaft member 51 via the candle stand receiving portion 71.

  (7) As described above, in the present embodiment, the lantern body 3 and the transparent glass plate 8 are detachably supported with respect to the rotation support 5 having a mechanism for rotating around the shaft member 51 while supporting the lantern body 3. A supporting member 93, a candle supporting portion 7 and a reflecting plate 10 are attached. When the lower end portion of the shaft member 51 is press-fitted into the hole 21 formed in the center of the upper surface of the base 2, the lower end portion of the shaft member 51 is bent while the wing member 52 is bent upward according to the press-fitting operation. Enters the hole 21 and the tip of each blade member 52 engages with the inner wall surface of the hole 21 so that the rotation support 5 is firmly fixed to the base 2. Of course, it is also possible to remove the rotation support part 5 from the base 2 by moving the rotation support part 5 in the reverse direction, that is, upward in the vertical direction. Thus, in this embodiment, the rotation support part 5 is detachable from the base 2.

  (8) When the mounting and fixing of the rotation support portion 5 to the base 2 is completed in this way, the transparent glass plate 8 is lowered from the upper side, and the lower end portion of the transparent glass plate 8 is fitted into the glass receiving portion 931 of the support member 93, In this way, the transparent glass plate 8 is attached to the rotation support portion 5. Thereafter, the lantern main body 3 is further placed and fixed on the upper surface of the second flat plate 54 while being engaged with the spring portion 932, and finally the head 4 is inserted into the upper end of the lantern main body 3. In this embodiment, the head 4 is configured to be detachable with respect to the lantern body 3, but when it is desired to fix the head 4 to the lantern body 3, What is necessary is just to fix the head 4 using an adhesive agent when the part 4 is inserted.

  In the present embodiment, the transparent glass plate 8 and the lantern body 3 are made detachable from the rotation support 5 by using the support member 93 configured as described above. With reference to FIG. It explains in detail. The support member 93 fixed to the upper surface of the second flat plate 54 is separated from the fence portion 543 erected on the outer peripheral edge of the second flat plate 54 to the through hole side (left hand side in FIG. 4), and the upper surface of the second flat plate 54. It is fixed to. Then, until the lantern main body 3 is placed on the second flat plate 54, the spring portion 932 is slightly inclined toward the anti-through-hole side (the right hand side in FIG. 4), as shown in FIG. When the transparent glass plate 8 is lowered from above and the transparent glass plate 8 is installed and fixed on the support member 93, the transparent glass plate 8 is guided by the spring portion 932 even if the transparent glass plate 8 slightly fluctuates. The end can be reliably inserted into the glass receiving portion 931.

  When the installation of the transparent glass plate 8 is completed, the lantern main body 3 is lowered from above and fitted onto the transparent glass plate 8 and the support member 93 as shown in FIG. During this external fitting operation, the inner wall surface of the lantern body portion 3 engages with the spring portion 932, pushes the spring portion 932 toward the transparent glass plate 8, and is sandwiched between the outer peripheral surface of the transparent glass plate 8. Further, in the present embodiment, the width of the spring portion 932 in the horizontal direction orthogonal to the axial direction X is wider than the distance between the transparent glass plate 8 and the lantern body portion 3, so as shown in FIG. The spring portion 932 sandwiched between the lantern body portion 3 and the transparent glass plate 8 is forcibly expanded in the axial direction X to urge the transparent glass plate 8 and the lantern body portion 3 in a direction away from each other, and is transparent. The lantern body 3 is fixed to the glass plate 8.

  In the present embodiment, the inner diameter of the space surrounded by the fence portion 543 is substantially the same as the outer diameter of the lower end portion of the lantern body portion 3, and the lower end portion of the lantern body portion 3 is inserted into the space. Since the center of gravity of the lantern main body 3 is designed to be positioned above the vertical direction of the shaft member 51, the lantern main body 3 can be accurately positioned only by being mounted and fixed to the rotation support 5. In addition, the lower end of the lantern body 3 can be held by the fence 543 and the lantern body 3 can be firmly fixed to the rotation support 5. Of course, the transparent glass plate 8 is supported by the two support members 93, and the lantern body portion 3 is fixed to the rotation support portion 5 by being supported by the two support members 93 and the fence portion 543. The lantern body 3 and the transparent glass plate 8 can be removed from the rotation support 5 by lifting the lantern body 3 upward and then lifting the transparent glass plate 8 upward. As described above, in this embodiment, the transparent glass plate 8 and the lantern main body 3 can be easily attached to and detached from the rotation support portion 5, and excellent maintainability can be obtained.

  As described above, in the present embodiment, with the lower end portion of the shaft member 51 fixed to the base 2, the central portion and the upper end portion of the shaft member 51 protrude upward from the upper surface central portion of the base 2. ing. And while fixing the 1st flat plate 53 with respect to the center part of the shaft member 51, the 2nd flat plate 54 is set with respect to the upper end part of the shaft member 51 above the 1st flat plate 53 via the six spherical bodies 55. It is pivotally supported. Therefore, by fixing the lantern body 3 and the transparent glass plate 8 to the upper surface of the second flat plate 54, the lantern body 3 and the transparent glass plate 8 are stably rotated about the rotation axis extending in the vertical direction from the shaft member 51. Can be made. Thus, by using the rotation support part 5 configured as described above, even the lantern body part 3 formed of a hollow stone material can be stably rotated. Accordingly, when the lantern body 3 is rotated and positioned so that the opening 33 faces the front, the hollow interior of the lantern body 3 is accessed from the opening 33 and the candle holder 72 is attached to and detached from the candle holder 71. Or igniting the candle 6 disposed in the hollow interior of the lantern body 3. In addition, after the candle 6 is ignited, the lamp 6 is led through the opening 31 when the lantern body 3 is rotated and positioned so that the opening 31 having the lattice pattern faces the front. By using the rotation support portion 5 in this way, the lantern body portion 3 can be rotated, and the candle 6 can be ignited smoothly.

  Moreover, in the said embodiment, the sphere 55 rolls between the 1st flat plate 53 and the 2nd flat plate 54, and the lantern main-body part 3 and the transparent glass plate 8 are rotated, and the base 2 and the lantern main-body part 3 are made. In addition to not colliding or rubbing, neither the base 2 nor the lantern body 3 will rub against the rotation support 5, and dust is prevented from being generated from the base 2 or the lantern body 3. be able to.

  Moreover, in the said embodiment, although the reflecting plate 10 is arrange | positioned at the back surface of the candle 6 supported by the candle support part 7, and the light from the candle 6 is reflected to the front, this reflecting plate 10 has only a reflective function. Rather, during normal use (when the opening 31 with the lattice pattern faces the front and the light of the candle 6 is taken out to the front side), the opening 33 located on the back side as shown in FIG. The function to block the candle and make the candle 6 hard to disappear.

  Moreover, in the said embodiment, it can prevent that a user touches the fire of the candle 6 through the said opening part 31, providing a lattice pattern part in the opening part 31, ensuring visibility. Moreover, since the transparent glass plate 8 is provided so as to close the opening 31, it is possible to prevent the fire of the candle 6 from extinguishing due to wind entering from the opening 31 with the lattice pattern while ensuring visibility. it can.

  Furthermore, in the above embodiment, since the first flat plate 53 has a simple flat plate shape, even if the wax of the candle 6 melts and falls down along the shaft member 51, the first flat plate 53 is guided and discharged outside the periphery of the rotation support portion 5. To do. Therefore, it is possible to effectively prevent the wax from staying in the rotation support portion 5 and deteriorating the rotation performance. While the stone lantern 1 is being used, dust such as sand and dust may enter between the first flat plate 53 and the second flat plate 54. Since the flat plate 53 is used, it is easy to remove dust and has excellent maintainability.

  Thus, in this embodiment, the lantern main body 3 corresponds to the “rotated body” of the present invention, the lattice pattern formed in the opening 31 corresponds to the “lattice-shaped portion” of the present invention, and transparent glass The plate 8 corresponds to the “transparent member” of the present invention.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention. For example, as shown in FIG. 5, the second flat plate 54 may be finished in a simple flat plate shape. In FIG. 5, priority is given to clarifying the arrangement relationship of each part of the device, and a part of the dimensional relationship of each part of the device is out of the actual product.

  In the embodiment shown in FIG. 5, the second flat plate 54 has a simple flat plate shape, that is, the fence portion 543 is not provided. Further, as shown in the figure, the support member 93 is arranged substantially symmetrically with respect to the rotation center axis AX extending from the shaft member 51 in the vertical direction. Therefore, the urging forces generated by the spring portions 932 act in opposite directions from the rotation center axis AX, and support the lantern body portions 3 while pressing them against the glass plate 8 in directions shifted by 180 ° from each other. For this reason, the lantern main body 3 is not simply placed on the upper surface of the second flat plate 54, but by the biasing force of the spring portion 932 via the glass plate 8 fixed by the glass receiving portion 931 of the support member 93. It is fixed to the rotation support part 5.

  Moreover, in the said embodiment, although the shaft member 51 is fixed to foundations, such as a base and a ground, and the 1st flat plate 53 is being fixed with respect to the shaft member 51, as shown in FIG. While fixing the flat plate 53 to a base such as a base, the shaft member 53 may be fixed to the first flat plate 53. Hereinafter, a third embodiment of the present invention will be described with reference to FIG.

  FIG. 6 is a view showing a stone lantern equipped with a third embodiment of the rotation support device according to the present invention. The third embodiment is greatly different from the first embodiment in the manner of fixing to the base 2 as described above, and the other configurations are basically the same, so that the details will be described mainly with respect to the differences. The same reference numerals are assigned to the same components, and the description of the components is omitted.

  In the third embodiment, the shaft member 51 includes the shaft piece 512 employed in the first embodiment and a ring-shaped shaft piece 513. Among these, in the through hole of the shaft piece 513, a female screw that can be screwed with the male screw of the shaft piece 512 is engraved, and the lower end portion of the shaft piece 512 is screwed into the shaft piece 513. The shaft member 51 can be configured by being integrated with the piece 513. In an example of the procedure for fixing the shaft member 51 thus configured to the first flat plate 53, the shaft piece 513 is welded to the center of the upper surface of the first flat plate 53 as indicated by reference numeral (3 ′) in FIG. Then, the lower end portion of the shaft piece 512 is screwed into the through hole of the shaft piece 513. By doing so, the shaft member 51 is erected upward from the center of the upper surface of the first flat plate 53.

  And the rotation support part 5 can be assembled by the procedure similar to the procedure (4)-(6) of 1st Embodiment, and the assembled rotation support part 5 is a lantern main-body part similarly to 1st Embodiment. 3 and a mechanism for rotating the shaft member 51 around the shaft member 51. Subsequently, a support member 93, a candle support part 7, and a reflector 10 that detachably support the lantern body part 3 and the transparent glass plate 8 are attached to the rotation support part 5, and then the lower surface of the first flat plate 53. Is fixed to the upper surface (horizontal plane) 22 of the base 2 with an adhesive or a double-sided tape (see reference numeral 7 ').

  When the mounting and fixing of the rotation support part 5 to the base 2 is completed in this way, the transparent glass plate 8 is attached, the lantern body part 3 is fixed to the upper surface of the second flat plate 54, and the lantern body, as in the first embodiment. The head 4 is inserted into the part 3 to complete the stone lantern 1.

  As described above, the mechanism for rotating the lantern body 3 is exactly the same as that of the first embodiment, although the method for mounting and fixing the rotation support 5 to the base 2 is different in the third embodiment as well. The same effect as the embodiment can be obtained. Moreover, as is clear from the comparison between FIG. 3 (first embodiment) and FIG. 6 (third embodiment), in the third embodiment, the step (1) of providing the hole 21 in the base 2 is unnecessary. In addition, the step (2) of providing the wing member 52 is unnecessary, and the configuration of the rotation support portion 5 can be simplified as compared with the first embodiment, and the working efficiency can be improved.

  Moreover, in the said embodiment, although the 1st flat plate 53 is finished in simple flat plate shape, it cannot be overemphasized that a fence part may be erected in the outer periphery.

  In the above-described embodiment, six concave portions 542 are provided in the second flat plate 54 and one spherical body 55 is accommodated in each concave portion 542. However, the number of the spherical bodies 55 to be accommodated in the concave portions 542 is particularly limited. For example, a plurality of pieces may be accommodated. In addition, it is not an essential component of the present invention that the number of the concave portions 542 matches the number of the spheres 55. For example, three or more spheres 55 may be accommodated in one annular concave portion. Good. In order to support the second flat plate 54 so as to be horizontally rotatable with respect to the first flat plate 53, three or more spheres 55 may be provided. It is desirable to provide the number to some extent, for example, about six as in the above embodiment.

  Further, in the above-described embodiment, the recess for accommodating the spherical body 55 is provided in the second flat plate 54, but the recess may be provided on the upper surface of the first flat plate 53. That is, it is only necessary to form a concave portion on the surface facing the other flat plate with respect to one of the first flat plate and the second flat plate, and to accommodate the sphere in a rollable manner within the concave portion.

  Moreover, in the said embodiment, although the shaft member 51 is comprised by connecting two shaft pieces 511 and 512 (or 512, 513), you may comprise the shaft member 51 by a single shaft piece, The shaft structure and the manner of fixing to the first flat plate 53 (mechanical connection with screws or the like, welding, adhesive, etc.) are also arbitrary. Further, the shaft piece 512 may be constituted by a plurality of members. For example, the shaft piece 512 may be used as a shaft piece 512 with a ring member such as a washer attached to the upper surface of the male screw member. In this case, a ring member corresponding to the inner diameter of the through hole 541 can be used. Further, the clearance between the flat plate 54 and the candle stand receiving portion 71 can be adjusted by changing the thickness of the ring member.

  Moreover, in the said embodiment, by providing a clearance between the flat plate 54 and the candle stand receiving portion 71, the second flat plate 54 and the lantern body portion 3 are integrated with the candle stand receiving portion 71 and the reflecting plate 10 fixed. However, it is configured so that a felt or resin ring-shaped member is inserted between the flat plate 54 and the candle stand receiving portion 71 so that the clearance is eliminated. May be.

  Moreover, in the said embodiment, although the lantern main-body part 3 and the head 4 are manufactured separately, and both are combined, you may manufacture the lantern main-body part 3 and the head 4 integrally in advance. Further, a stone lantern may be configured by rotatably supporting the lantern main body 3 alone by a rotation support portion. However, in this case, in order to prevent raindrops, winds and the like from entering the inside of the lantern main body 3, it is desirable that the lantern main body 3 is finished in a hollow shape provided with a ceiling surface.

  Moreover, in the said embodiment, although the support member 93 is used in order to fix the lantern main-body part 3 to the 2nd flat plate 54, the fixing method to the 2nd flat plate 54 of the lantern main-body part 3 is limited to this. Rather, any fixing method can be used. For example, it may be fixed with an adhesive. In this regard, the same applies to the fixing of the transparent glass plate 8. For example, the transparent glass plate 8 may be attached to the second flat plate 54 with an adhesive. Or you may fix the transparent glass plate 8 to the lantern main-body part 3 fixed to the 2nd flat plate 54 with the adhesive agent.

  Moreover, in the said embodiment, in order to prevent a user touching the fire of the candle 6 through the opening part 31 while ensuring visibility at the time of normal use, while forming a lattice pattern part in the opening part 31, and transparent Although the glass plate 8 is provided, only one of them may be employed. However, it is desirable to provide at least the transparent glass plate 8 from the viewpoint of preventing the wind from entering through the opening 31 and extinguishing the candle 6.

  Moreover, in the said embodiment, although the lantern main-body part 3 formed with the hollow stone material is rotated with respect to the base 2 by the rotation support part 5 as the "to-be-rotated body" of this invention, You may comprise so that a hollow stone material and a stone pillar may be rotated with respect to the base 2 by the rotation support part 5 as the "to-be-rotated body" of this invention. For example, a column-shaped grave magazine can be fixed to the upper surface of the second flat plate 54 using an adhesive or a fixing bracket as a “rotated body”, and the grave magazine can be rotated by the rotation support portion 5. In this way, the rotating body is not affected by the upper surface of the second flat plate 54 even if the rotating body is a stone pillar without any processing on the rotating body such as a tomb magazine. It can be smoothly rotated around the shaft member 51 while being supported. Further, when the center of gravity of the rotated body is not positioned above the vertical direction of the shaft member 51, the rotation of the rotated body becomes unstable. In this case, the center of gravity of the rotated body is not in the vertical direction of the shaft member 51. The rotation can be easily stabilized by adjusting the position of the rotated body on the second flat plate 54 so as to be positioned above. Furthermore, since the rotated body is rotated by rolling the sphere 55 between the first flat plate 53 and the second flat plate 54, the base 2 and the rotated body are similar to the embodiment shown in FIG. Not to collide or rub against each other, and neither the base 2 nor the rotated body will rub against the rotation support portion 5 to prevent dust from being generated from the base 2 or the rotated body. Can do.

  Moreover, in the said embodiment, the drilling hole 21 is formed in the upper surface center part of the exclusive base 2 used for the stone lantern 1, and the rotation support part 5 is fixed, or the lower surface of the 1st flat plate 53 is used for the base 2 of the base 2. Although it is fixed to the upper surface 22, for example, the rotation support 5 may be fixed to a part of a stone monument, and thus a stone lantern is constructed using the stone monument or the like as the “base” of the present invention. May be. In addition to the base, a hole may be formed in the ground such as the ground or rock, and the rotation support 5 may be directly fixed to the ground. In addition, the method of fixing the lower end portion of the shaft member 51 of the rotation support portion 5 to the base such as the base 2 or the ground is not limited to the method described in the above embodiment, but can be arbitrarily fixed. The method can be adopted. For example, the lower end portion of the shaft member and the first flat plate may be fixed to a base such as a base or the ground using an adhesive or concrete.

  The present invention is applied to a rotation support device that rotatably supports a rotating body formed of a stone pillar or a hollow stone material with respect to a foundation such as a base or a ground, and to stone lanterns generally equipped with the rotation support device. Can do.
