Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a core material for decorative barrels such as decorative komo barrels used in shrines, taverns, etc.

Traditionally, it has been the first choice as the core material for this type of decorative barrel.
As shown in Fig. 7, a hollow barrel-shaped case 51 with legs 50 is
The split case parts 51A, 51A are each made of styrofoam, and the split case parts 51A, 51A and the leg part 50 are formed in directions perpendicular or almost perpendicular to the split surfaces of the split case parts 51A, 51A and the leg part 50. By forming recessed and recessed parts 54a and 54b that can be fitted together, and by fitting these recessed and recessed parts 54a and 54b to each other, both divided case parts 51A and 51A are formed.
In addition, one weight member 53 for stabilizing the posture, such as a brick, is placed in the center of the bottom plate of the case 51 in a position spanning the bottom plates 51a, 51a of the two divided case parts 51A, 51A. However, in order to maintain the overall shape of the case 51 in a predetermined shape over a long period of time, a large amount of material such as foamed polystyrene is required, which has the disadvantage of increasing manufacturing costs.

That is, since the weight member 53 for posture stabilization is placed at the center of the bottom plate, the bottom plate 51
In order to eliminate the disadvantage that the weight of the weight member 53 acts concentratedly on the central part along the dividing plane a, and the bottom plate 51a tends to sag downward, these two divided case parts 51 are
A, 51A requires a pair of left and right reinforcing plates 52, 52 in a vertical position perpendicular to the dividing plane to extend from the top plate to the bottom plate 51a, and
Since the weight of the weight member 53 also acts on the reinforcing plates 52, 52 via the bottom plate 51a, stress tends to concentrate at the connection between the bottom plate 51a and the reinforcing plates 52, 52, and cracks occur at this connection. In order to prevent the bottom plate 51a from being damaged by this, it is necessary to make the wall thickness of this connecting portion sufficiently large and to reinforce it, resulting in a structure that requires a large amount of material as a whole.

The present invention has been made in view of the above-mentioned circumstances, and by devising the arrangement of the weight members, it is possible to reduce the amount of materials used and to create a decorative product that is easy to maintain in a predetermined shape over a long period of time. The purpose is to provide core material for barrels.

In order to achieve the above object, the core material of the decorative keg according to the present invention has a hollow barrel-shaped case made of a lightweight material with annular legs integrally connected to the lower surface of the bottom plate along the circumferential direction. It is divided into a plurality of divided case parts along an imaginary vertical plane passing through its center, and on the upper surface side of the bottom plate of each of these divided case parts, there are two positions spaced apart in the direction along the dividing plane, and the above-mentioned A pair of recesses for fitting the weights are formed near the upper part of the continuous leg part so that the recesses of adjacent split case parts face each other on the split surface, and each of these opposing recesses In this step, the posture stabilizing weight members fitted into both of the opposing recesses across the dividing plane are fitted and held in a state where movement in the upward and lateral directions is prevented, and the posture stabilizing weight members are They are arranged in a dispersed manner, and this configuration provides the following effects.

That is, the weight member is rigidly fitted and held in the recess of the split case part to reliably prevent accidental upward and lateral movement during lashing of the outer cover material, and This weight member is also used as a joining member for both divided case parts, and on the upper surface side of the bottom plate of each of these divided case parts, there are two positions spaced apart in the direction along the divided surface, and the above-mentioned legs. A pair of recesses for inserting the weights are formed near the upper part of the part where the parts are connected so that the recesses of the adjacent divided case parts face each other on the dividing surface. Instead of placing the weight members in a fixed position in the center of the bottom plate of the case, the weight members are placed in a position such that they straddle both of the recesses facing each other on the dividing surface. Since the weight members are arranged in a distributed manner, the weight of the weight members is distributed and acts on the bottom plate, and the bottom plate of each divided case portion is not easily sagged downward due to the weight of the weight members.

Furthermore, since the recess is formed near the upper part of the leg part and the weight member is fitted and held in the recess, the weight of the weight member is effectively distributed to the leg part. This makes it possible to further suppress sagging of the bottom plate.

Therefore, there is no need to install a large reinforcing material that spans the top plate and the center of the bottom plate as in the past.
In addition, this eliminates the need to assume a situation such as a crack occurring at the joint between the reinforcing member and the bottom plate, so it is possible to maintain the specified shape for a long period of time with less material than before. We have now been able to provide core material for decorative barrels.

Furthermore, as shown in the embodiments described later, the means for preventing upward movement of the weight member utilizes a reinforcing plate connected to the split case part in a state in which the weight member is in contact with the upper surface of the weight member. In this case, there is an advantage that the structure for preventing movement of the weight member can be simplified by using the reinforcing plate provided to increase the strength of the divided case portion.

Embodiments of the present invention will be described below based on the drawings.

To constitute the core material of the decorative barrel shown in Figures 1 to 4, a hollow barrel-shaped case 2 made of expanded polystyrene with annular legs 1 connected to the bottom is passed through the center of the case 2. It is divided into two on an imaginary vertical plane, and on the upper surfaces of the bottom plates 2a, 2a of both of these divided case parts 2A, 2A, on the left and right sides of the part corresponding to the continuous connection of the leg part 1, respectively, on the dividing surface of the divided case parts 2A, 2A. At the same time, the recesses 3, 3 and 3, 3 are formed in a position orthogonal to the recesses 3, 3 and 3, 3, and the positions of bricks, concrete, etc. The weight members 4, 4 are fitted and held in a flexible state, and further, on the inner peripheral surfaces of the peripheral walls 2b, 2b of the divided case parts 2A, 2A, from the opening periphery thereof to an appropriate length in the circumferential direction. The weight members 4, 4 are positioned close to the upper surfaces of the weight members 4, 4 fitted and held across the recesses 3, 3 and 3, 3.
Reinforcement plates 5, 5 and 5, 5 in a horizontal or almost horizontal posture that prevent upward extraction movement are provided in series, and the weight members 4, 4 for stabilizing the posture are
