に樹脂を注入している。 Traditionally, this type of pattern was used, for example, in the 1970s.
There is one shown in Publication No. 21441. The same handle has three metal support rods extending in the longitudinal direction on the grip part, and their axes are connected to each other to form a triangular cross-sectional shape, with a space between them communicating with each other. The resin is injected into this space.
ところが、中央の支杆が片持ち状になるため、
この支杆が樹脂の注入圧力により振れ易くなつて
位置ずれするおそれがあつた。 However, because the central support rod becomes cantilevered,
There was a risk that this support rod would tend to swing due to the injection pressure of the resin, causing it to become misaligned.
本発明の目的は、把持部分の合成樹脂を支持す

In this state, the axis P1 of the support rods 4 and 5,
The cross-sectional shape M formed by connecting P2 to each other has a substantially isosceles triangular shape, and spaces S1 and S2 are formed between the support rods 4 and 5 so as to communicate with each other. This cross-sectional shape M has a center-to-axis distance of P2 to P3.
is larger than P1 to P2, so it becomes flat.

又、柄１の先端部を第７図に示すように柄１の後
面側へ湾曲させる。 Note that the proximal end 6 of the handle 1 is bent as shown in FIG. 7 to form a hook portion, and the hook hole 7
As shown in Fig. 6, spread it out to both the left and right sides of the handle 1.
Further, the tip of the handle 1 is curved toward the rear side of the handle 1 as shown in FIG.

４，５を互いに離間させたので、合成樹脂９の注
入前の骨組をスポツト溶接等を必要とすることな
く容易に形成することができる。 As described above, in the method for manufacturing a handle according to the present invention, two discontinuous cuts 3 are formed in the gripping portion 2 of the handle 1 made of a single metal material in the longitudinal direction of the handle 1, and then Since the three support rods 4 and 5 separated by the notches 3 are spaced apart from each other, the frame before injection of the synthetic resin 9 can be easily formed without the need for spot welding or the like.

振れることなく、支杆４の位置ずれを防止するこ
とができる。 In particular, in this method invention, two cuts 3
Since it is formed discontinuously, the central support rod 4 has a dual-supported shape, making it difficult for the support rod 4 to swing. Therefore,
During molding, the resin 9 is applied to the spaces S1 and S between each support rod 4 and 5.
When injecting the liquid into the injection tube 2, the support rod 4 does not swing due to the injection pressure, and displacement of the support rod 4 can be prevented.
