Description

Technical Field

[0001] The present invention relates to a side plate connection structure of a coffin and a coffin provided with the connection structure.

Background Art

[0002] <00000-- 09>Conventionally, in funeral companies and the like, coffins are carried in in the state of finally assembled finished products, so there has been a problem that a large space is required for their storage and transportation. Therefore, various collapsible coffins that can be folded compactly during storage and transportation and assembled at the site (such as a funeral hall) where they are used have been proposed (for example, see Patent Document 1).

[0003] These conventional collapsible coffins generally have a structure in which side plates are connected to a bottom plate via hinges or the like, and are folded during storage and the side plates are raised during use to form a box-shaped coffin.

[0004] [[ID=2-- 0]]However, in conventional collapsible coffins, when placing the deceased in the coffin after assembly, it is necessary to lift the deceased from above and place it in the coffin so as to exceed the already raised and fixed side plates (for example, about 40 cm in height). In recent years, in funeral homes and the like, there has been an increasing number of cases where employees have to perform the coffin placement work with a small number of people (for example, one person), and the work of lifting the deceased to the height of the side plates and placing it in the coffin has been a very heavy labor burden for the workers.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Therefore, the problem that this invention aims to solve is to provide a coffin that allows the deceased to be smoothly placed inside by sliding them in from the side without having to lift them high during the encoffining process, thereby reducing the burden on workers, even with a small number of people. [Means for solving the problem]

[0007] To solve the above problems, the coffin side panel connecting structure according to the present invention is a coffin side panel connecting structure, wherein the coffin comprises a bottom plate, left and right side plates, and a first frame member extending in the front-rear direction, fixed at at least one of the left and right ends in the longitudinal direction of the bottom plate. The first frame member and the side plate located on the side of the left and right side plates are provided with a locking structure that engages them with each other and maintains a connected state by sliding the side plates in the front-rear direction.

[0008] Preferably, the coffin's side panel connecting structure further comprises a plurality of fixing members. The fixing members are formed to extend in the front-rear direction and are configured to be fixable to at least one of the first frame member or the left and right side panels. At least one of the first frame member or the left and right side panels is provided with a transverse hole that penetrates in the left-right direction. The transverse hole is formed to extend in the front-rear direction and is keyhole-shaped, having a wide portion and a narrow portion communicating with the wide portion. The fixing member fixed to at least one of the first frame member or the left and right side panels protrudes from the first frame member or the left and right side panels in the left-right direction, and the protruding portion of the fixing member is formed in a transverse T-shape in cross-section. The first frame member and the side panels are configured to be connected to each other by passing the protruding portion of the fixing member through the transverse hole and sliding the side panel in the front-rear direction.

[0009] The side panel connecting structure of the coffin described above is configured such that, for example, the fixing member is formed in an H-shape in cross-section, and lateral holes are formed in both the first frame member and the side panel, and the fixing member is fixed by sliding in the front-rear direction through the lateral holes in the first frame member or the side panel.

[0010] Preferably, the side panel connecting structure of the coffin described above is provided with an L-shaped notch that penetrates in the thickness direction and an engaging notch that extends in the front-rear direction and is spaced apart from the L-shaped notch. The side panel connected to the first frame is provided with a rod-shaped projection that extends inward from the side and an L-shaped projection with an inverted L-shaped cross-section that extends inward from the side. The side panel moves from top to bottom, bringing the rod-shaped projection into contact with the upper inner edge of the L-shaped notch and the L-shaped projection into contact with the engaging notch. Then, by sliding the side panel in the front-rear direction, the rod-shaped projection is locked into the L-shaped notch and the L-shaped projection into the engaging notch, thereby connecting them.

[0011] To solve the above problems, the coffin according to the present invention comprises a canopy, a bottom plate, a front plate, a rear plate, a left side plate, a right side plate, and a first frame member and a second frame member extending in the front-rear direction at the left and right ends of the bottom plate. One of the left and right plates is configured to be connected to the first frame member by the side plate connecting structure, and the other of the left and right plates is connected to the second frame member via a plurality of hinges. The side plate connected to the second frame member and the second frame member are provided with a fall prevention structure that maintains the upright position of the side plate. [Effects of the Invention]

[0012] The coffin according to this invention allows the deceased to be smoothly placed inside by sliding them in from the side without having to lift them high during the encoffining process, thus reducing the burden on workers even with a small number of people.

[Figure 8] Figure 7 is a perspective view showing how the left panel is connected to the first frame member by the side panel connecting structure shown. [Modes for carrying out the invention]

[0014] The side plate connecting structure according to the present invention and one embodiment of a coffin equipped with said connecting structure will be described in detail below with reference to the attached figures. In the figures, double arrows X indicate the left-right direction, double arrows Y indicate the front-back direction, and double arrows Z indicate the up-down direction.

[0015] <Composition of the coffin> Figure 1A is a perspective view showing the coffin 1 according to this embodiment, and Figure 1B is an enlarged view of part B of A. Figure 2A is a perspective view showing the bottom plate 12 etc. which will be described below, and Figure 2B is an enlarged view of part B of A.

[0016] As shown in Figure 1A, the coffin 1 mainly comprises a canopy 10, a bottom board 12 on which the body is placed, a front board 14, a rear board 16, a left side board 18, and a right side board 20. As shown in Figure 2A, the left and right ends of the bottom board 12 in the longitudinal direction are provided with first frame members 22 and second frame members 24, which extend in the front-to-back direction, respectively. In addition, the front and rear ends of the bottom board 12 in the short direction are provided with third frame members 26 and fourth frame members 28, which extend in the left-to-right direction, respectively.

[0017] The materials of the bottom plate 12, front plate 14, rear plate 16, left side plate 18, right side plate 20, and each frame member 22, 24, 26, 28 constituting the coffin 1 are not particularly limited. For example, in addition to wood-based materials such as natural wood, plywood, and MDF (medium density fiberboard), paper-based materials such as reinforced cardboard, or lightweight and high-strength synthetic resin materials may also be used.

[0018] The left side plate 18 is detachable from the first frame member 22 and has a locking structure that is firmly connected by sliding in the front-rear direction.

[0019] FIG. 3 is a perspective view showing a state in which a fixing member, which will be described later, is removed at portion B of FIG. 2A. As shown in FIGS. 2B and 3, a plurality of horizontal holes 22a penetrating in the left-right direction are provided in the first frame member 22. Further, as shown in FIGS. 1B and 5, horizontal holes 18a penetrating in the left-right direction are also provided in the lower part of the left side plate 18. These horizontal holes 22a, 18a are formed to extend in the front-rear direction and are formed in a keyhole shape having a wide portion and a narrow portion communicating with the wide portion.

[0020] To connect the first frame member 22 and the left side plate 18, the fixing member 30 shown in FIG. 4 is used. The fixing member 30 includes a central plate portion 30a and side portions 30b, 30c that project at both left and right ends thereof, and is formed in an H-shaped cross section as a whole. The fixing member 30 is preferably integrally formed of a metal material or a hard resin material so as to withstand friction and load during sliding.

[0021] <Connection method of the left side plate> At the time of connection, first, one side portion 30c of the fixing member 30 is passed through the wide portion of the horizontal hole 22a of the first frame member 22 and slid in the front-rear direction to engage with the narrow portion. In this state, the projecting portions (central plate portion 30a and the other side portion 30b) of the fixing member 30 project from the first frame member 22 to the left (outer side) and function as a rail having a horizontal T-shaped cross section.

[0022] Next, when attaching the left side plate 18, the wider portion of the horizontal hole 18a is passed through the protruding portion of the fixing member 30 to align it, and the left side plate 18 is slid in the front-to-back direction. As a result, the central plate portion 30a of the fixing member 30 enters the narrow portion of the horizontal hole 18a, and the side portion 30b locks onto the outer surface of the left side plate 18, thereby firmly connecting the left side plate 18 to the first frame member 22 while preventing it from coming loose upwards or falling outwards. The sliding distance (stroke amount) required to slide the left side plate 18 in the front-to-back direction relative to the first frame member 22 to complete the connection is preferably set in the range of 3 cm to 15 cm. Within this range, the worker is not forced to perform excessive movement operations, and detachment due to unexpected impact can be prevented.

[0023] <Method for connecting the right-side panel> Next, the method of connecting the right side panel 20 will be described. As shown in Figure 2A, a square timber 20a is fixed to the inner surface of the right side panel 20 below the center. The square timber 20a of the right side panel 20 is connected to the second frame member 24 via a plurality of hinges 32. As a result, the right side panel 20 is configured to open and close so as to tilt inward. Furthermore, the square timber 20a of the right side panel 20 connected to the second frame member 24 and the second frame member 24 are provided with a fall prevention structure that maintains the right side panel 20 in an upright position.

[0024] Specific examples of the anti-tipping structure are shown in Figures 6A and 6B. In the example shown in Figure 6A, the corner timber 20a at the lower end of the right side plate 20 and the second frame member 24 are provided with locking holes 20c and 24a, respectively, and these locking holes 20c and 24a form a single locking hole.

[0025] Then, the locking pins 34 are inserted from above into the locking holes 20c provided in the square timber 20a and the locking holes 24a provided in the second frame member 24, thereby fixing the open angle, that is, the upright position of the right side panel 20. Multiple locking holes 20c and 24a may be provided in the square timber 20a and the second frame member 24, in which case multiple locking pins 34 will be inserted.

[0026] Furthermore, in the example shown in Figure 6B, the second frame member 24 is provided with a plurality of rotatable stoppers 36. As shown in Figure 6B, by rotating the tips of these plurality of stoppers 36 upward and contacting and locking them against the square member 20a of the right side plate 20, the right side plate 20 is physically prevented from tilting in the direction of closing inward. In this embodiment, the stoppers 36 are provided on the second frame member 24, but the stoppers 36 may also be provided on the square member 20a. In this case as well, by rotating the tips of the stoppers 36 downward and contacting and locking them against the second frame member 24, the right side plate 20 is physically prevented from tilting in the direction of closing inward.

[0027] The structures shown in Figures 6A and 6B prevent the right-side panel 20 from unexpectedly falling over during the coffin-laying process, thus ensuring a safe working environment.

[0028] As shown in Figures 2A, 7, and 8, the inner surfaces of the front and rear ends of the left and right side plates 18 and 20 are provided with vertically extending engaging projections 18b and 20b, respectively. Although not shown, the sides of the front plate 14 and rear plate 16 are provided with vertically extending engaging grooves. By engaging these engaging grooves with the engaging projections 18b and 20b of the left and right side plates 18 and 20 and sliding them downward, the front plate 14 and rear plate 16 are engaged with the left and right side plates 18 and 20. This restricts the front-to-back movement of the left and right side plates 18 and 20.

[0029] This configuration allows workers to remove the left-side panel 18 beforehand when placing the body in the coffin. With the left-side panel 18 removed, the body can be smoothly placed into the coffin by sliding it in from the side of the coffin 1 while maintaining an extremely low position, without having to lift the body high. After the body is placed inside, the left-side panel 18 can be easily attached with a single touch using the aforementioned sliding operation, thus significantly reducing the physical burden on workers, even when the coffin placement work is performed by a small number of people.

[0030] The side panel connecting structure according to the present invention and one embodiment of a coffin equipped with said connecting structure have been described above, but the side panel connecting structure and coffin according to the present invention are not limited thereto. For example, the side panel connecting structure according to the present invention may be implemented by the following modifications.

[0031] <Variation> Referring to Figures 7 and 8, a modified side plate connecting structure of the present invention will be described. In this modified structure, instead of using a separate fixing member 30, a sliding connecting structure is realized by directly processing the left side plate 18 and the first frame member 22. However, this is merely one example, and similar processing may be applied to the right side plate 20 and the second frame member 24 instead of, or together with, the left side plate 18 and the first frame member 22.

[0032] As shown in Figure 7, the upper part of the first frame member 22 is provided with an L-shaped notch 22b that penetrates in the thickness direction and is roughly L-shaped in side view, and an engaging notch 22c that extends in the front-rear direction and is spaced apart from the L-shaped notch 22b. On the other hand, the lower part of the inner surface of the left side plate 18 is provided with a cylindrical rod-shaped projection 18c that protrudes inward, and an L-shaped projection 18d that protrudes inward and has an inverted L-shaped cross-section with a flange-like lower end.

[0033] In the coupling operation, the left plate 18 is first moved vertically from top to bottom, so that the rod-shaped projection 18c is inserted through the upper opening of the L-shaped notch 22b and brought into contact with the bottom surface, and the L-shaped projection 18d is brought into contact with the opening of the engagement notch 22c.

[0034] Next, as indicated by the arrow in Figure 7, the left plate 18 is slid backward. As a result, as shown in Figure 8, the rod-shaped projection 18c enters the depth of the lateral groove of the L-shaped notch 22b, and the protruding portion of the L-shaped projection 18d engages with the engaging notch 22c. This sliding operation causes each projection to engage with the notch, preventing the left plate 18 from coming loose upward or tipping outward, thus achieving a stable connection quickly and easily while reducing the number of parts.
