Abstract
Description
[Technical Field]
[0001] The present invention relates to a bench. [Background technology]
[0002] The bench has a wooden seat and concrete arched base legs, and the seat and arched base are not integrated; the seat is simply placed on top of the arched base. The seat is made of a thick wooden board, so it will not be blown away by the wind, and is not fixed to the arched base. The reason for this is that when transporting the bench, the arched base and seat can be carried separately, making it easier to carry. [Prior art documents]
[0003] [Patent documents] [Patent documents] Problems to be solved by the invention of Patent Publication No. 2018-122067
[0004] However, if the seat plate is not fixed to the arched base, there is a risk that the seat plate may move and cause fingers to get caught between the seat plate and the arched base, resulting in injury.
[0005] To solve this problem, the present invention provides horizontal through holes in the seat plate and the arched base for passing bolts through, and fixes the seat plate to the arched base using bolts and nuts.
[0006] The seat can be fixed to the arched base, preventing fingers from getting pinched underneath. When transporting the bench, simply remove two bolts to disassemble the seat and arched base, allowing them to be carried separately. Since the fixed seat will not be blown away by the wind, synthetic resin, wood, or aluminum seats can also be used. [Brief explanation of the drawings]
[0007] [Figure 1] FIG. 10 is a perspective view of an arch-shaped base having a through hole for a bolt. [Figure 2] FIG. 10 is a perspective view of the back side of a seat plate having a through hole for passing a bolt therethrough. [Figure 3] This is an oblique view of a bench made by assembling an arched base and a seat using bolts. [Explanation of symbols]
[0008] 1 Bolt hole 2 Crosspiece 3 Crosspiece 4 Bolt through hole 5 Bolt through hole [Example]
[0009] To secure the seat plate to the arched base, horizontal through-hole 1 is drilled into the wall of the arched base as shown in Figure 1 to allow a bolt to pass through. Then, as shown in Figure 2, horizontal through-holes 4 and 5 are drilled through the centre of each of the two crosspieces 2 and 3 on the back of the seat plate to allow a bolt to pass through. The length from the centre of through-hole 1, which allows the bolt to pass through the arched base, to the top of the base should be the same as the length from the centre of through-holes 4 and 5 in the crosspieces of the seat plate to the top of each crosspiece. To secure the seat plate to the arched base, place two arched bases facing each other as shown in Figure 3, and then place the seat plate on the two arched bases. Then, pass bolts through the bolt holes in the seat plate and arched base and tighten them with nuts to secure the seat plate in place.
Claims
1. A concrete arched base with a single horizontal through-hole for a bolt in the upright arched projection
2. A wooden base plate with two crosspieces and one horizontal through hole for a bolt.
