Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a simple mahjong mat made of a flexible synthetic resin.

(Prior Art) Conventionally, it is known that a frame body b is fixed to the four peripheral edges on the surface of a rectangular plate-shaped mat body a in a frame shape with an adhesive c. This simple mahjong mat is
Since both the mat body a and the frame body b are made of a flexible synthetic resin such as vinyl chloride resin, they can be conveniently wound at a low price because they can be rolled up in a tubular shape and stored when unnecessary.

(Problems to be solved by the invention) The above-mentioned mat is fixed to the mat body a, the frame body b, and the adhesive c, and the frame body b has four independent peripheral edges. It is only joined and integrated at an angle. However, in the game, since the operation of aligning the "pai" with the frame strongly hitting the frame is repeated, the fixing and unifying means as described above cannot endure this at all, and peels off in a short time. There was a drawback.

(Means for Solving the Problem) As a means for solving the above-mentioned problems, the present invention provides a simple Mahjong mat made of a flexible synthetic resin on the four peripheral edges on the surface of a rectangular plate-shaped mat body 1. In a simple mahjong mat made of a flexible synthetic resin in which the frame body 2 is fixed in a frame shape, a cut step having the same height as the thickness of the mat body 1 except for a part 3 on the back side of the frame body 2. 4, the three corner portions 7, 7 and 7 are continuously arranged at an outer angle and are joined and integrated at a joining line 8, and the other corner portion 7 ′ is joined and integrally formed at a joining line 8 ′. Is formed into a frame shape, and the four peripheral edges of the mat body 1 are fitted into the cut step portions 4 on the back surface of the frame body 2, and the frame body 2 is formed at least at the inner and outer end portions 9 and 10 of the cut step portions 4.
Perforation-shaped welded portions 11 and 12 are provided along the longitudinal direction so that the frame body 2 and the mat body 1 are welded and integrated.

(Function) The Mahjong mat of the present invention is appropriately placed on a flat surface such as a desk to play the game. Since the back surface of the frame body 2 has a part 3 left on the outside, the frame made of this soft material is used. The part 2 of the body 2 does not move in contact with the top surface of the desk. Further, since at least three corner portions 7, 7, 7 of the frame body 2 are continuously provided at the outer corner and are integrated by the joining line 8, the corner portion 7 is not separated and separated. Moreover, the frame body 2 and the mat body 1 are fixed by fitting the four peripheral edges of the mat body 1 with the cut step portions 4 on the back surface of the frame body 2 and at least at the inner and outer end portions 9 and 10 in the longitudinal direction of the frame body 2. Along the perforated welds 11,12
Since the frame body 2 and the mat body 1 are welded and integrated with each other, even if the “pay” is strongly hit against the frame body 2 in the alignment of “pay”, they are not separated from each other.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings shown in FIGS.

The present invention comprises a square plate-shaped mat body 1 and a frame-shaped frame body 2. The former is a flexible synthetic resin plate of 1.5 to 2 mm and is made of, for example, a vinyl chloride material, and the latter is a flexible synthetic resin that is softer than the former, and is made of a vinyl chloride material like the former. The surface of the mat body 1 is a rough surface to prevent slippage. on the other hand,
The frame body 2 is formed by extrusion molding with its back surface having a cut step portion 4 having the same height as the thickness of the mat body 1 with a part 3 left outside. FIG. 3 is a development view of a frame body having the same length as the four circumferential walls of the mat body 1, and the development frame body 2'is a V-cut 5, 90 degrees angle of 90 degrees at three places in the middle of the quadrant.
5 and has 45 degree angled edges 6 and 6 at both ends. By bending the unfolding frame 2'to 90 degrees at the V-cut 5 portion and joining the slanted edges 6 and 6 at both ends, the three corner portions 7, 7 and 7 are continuously provided at the outer corners to form an adhesive. Is joined and integrated at the joining lines 8, 8 and 8, and the other one corner portion 7'is joined and integrated at the joining line 8'to form a frame. The outer corners of the three corners 7, 7 and 7 are bent, and as a result, this part becomes an arc shape and is not angular, but the other one corner part 7'is angular and therefore the part is arcuate. It has been excised. By the way, the four peripheral edges of the mat body 1 are fitted into the cut step portions 4 on the back surface of the frame body 2. Further, at least inner and outer end portions 9 and 10 of the cut step portion 4 are provided with perforated welding portions 11 and 12 along the longitudinal direction of the frame body 2 so that the frame body 2 and the mat body 1 are welded and integrated. There is.

(Effect of the Invention) In the present invention, since the back surface of the frame body 2 is partially left outside, the frame body 2 part 3 of the soft material does not move in contact with the desk top surface. Further, since at least three corner portions 7, 7, 7 of the frame body 2 are continuously provided at the outer corner and are integrated by the joining line 8, the corner portion 7 is not separated and separated. Moreover, the frame body 2 and the mat body 1 are fixed by fitting the four peripheral edges of the mat body 1 with the cut step portions 4 on the back surface of the frame body 2 and at least at the inner and outer end portions 9 and 10 in the longitudinal direction of the frame body 2. Since the perforation-like welded portions 11 and 12 are provided along the frame body 2 and the mat body 1 so as to be welded and integrated, even if the "pay" is strongly hit against the frame body 2 by the alignment of "pay", Both do not separate.
