Description

[Detailed explanation of the invention] This invention is a metal handle such as a knife, fork, spoon, etc.
This relates to a handle for metal western tableware that is made by welding a pair of plastic plates using high frequency or ultrasonic waves.

Conventionally, as shown in FIG. 1, in this type of tableware, window holes 11a and llb are bored in the handle rod 11 of metal western tableware.
A pair of plastic plates 1 to match a, 11 b
Utility Model Publication No. 51-292 formed by forming uneven parts 12a and 13a on the inner surface of 2.13 and welding them using high frequency or ultrasonic waves.
There is a pattern of metal Western tableware known from Publication No. 51.

It has been pointed out that in this type of product, since there are two matching parts, the crimping area is small and the durability is somewhat inferior.

In addition, since the end of the handle rod 11 is required to be the same as the plastic plate 12, 13, there are many metal parts and it becomes a little heavy to handle. It has been pointed out that since it has the same width as No. 3, it has poor retention when crimped.

The present invention solves this problem by creating a window hole in the handle of metal Western tableware by welding a pair of ABS, acrylic, or other plastic plates to the handle of metal Western tableware using high frequency or ultrasonic waves. A metal handle drilled in a suitable place, a shallow groove substantially the same as the handle below the inner surface wider than the handle, and a groove or protrusion in the shallow groove at a position corresponding to the edge of the window hole, and a groove or protrusion above the handle. A plastic plate on one side with a groove or protrusion formed thereon, a protrusion or groove that fits into the groove or protrusion through a window hole on an inner surface having the same width as the plastic plate, and a protrusion that fits into the upper groove or protrusion. or a plastic plate on the other side with grooves formed therein.

Next, an embodiment of the present invention will be described based on FIGS. 2 to 4.

1 is a metal handle rod shorter than the handle handle of metal Western tableware a,
Rectangular window holes 1a and lb are formed at two locations, upper and lower.

Reference numeral 2 denotes a plastic plate wider than the handle rod 1 on one side, which has a hole 2a for suspending it in the upper part, and a shallow groove 2b having almost the same shape as the handle rod 1 is formed in the lower part of the inner surface. The shallow groove 2b has the window hole 1a.

A pair of left and right vertical grooves 2C, 2 are provided at positions corresponding to both edges of 1b.
d is formed.

2e and 2f are horizontal grooves formed on both upper and lower sides of the window hole 2a.

Reference numeral 3 designates a plastic plate on the other side in which a window hole 3a is bored in relation to the window hole 2a, and the vertical grooves 2C, 2 are formed on the planar inner surface.
d has a pair of left and right set-like protrusions 3b, 3C that fit through the window holes 1a, lb, and horizontal protrusions 3d, 3e that fit into the lateral grooves 2e, 2f.

The plastic plate 3 has the same width as the plastic plate.

Note that 4 is a decoration applied to the surfaces of the plastic plates 2 and 3 by thermal transfer, film molding, hot stamping, or the like.

The handle rod 1 is placed in the shallow groove 2b, and the set projections 3 d and 3 e are fitted into the vertical grooves 2 C and 2 d through the holes 1 a and lb, and the horizontal projections 3 d and 3 e are fitted into the horizontal grooves 2 e and 2 f. The handle rod 1 is then sandwiched between a pair of plastic plates 2 and 3, and then welded from the outside using high frequency or ultrasonic waves.

Incidentally, appropriate circular, triangular, etc. window holes may be drilled at appropriate locations in the plastic plates 2 and 3 so that the metal handle rod 1 can be seen. The number may be increased or decreased depending on the size of the metal Western tableware a.

As such, the present invention has the following features.

1. Conventionally, the uneven parts 12a and 13a were fitted, but in the present invention, vertical grooves 2C92d and lateral grooves 2e and 2f are formed in the - side plastic plate 2, and the grooves are After fitting the assembled protrusions 3b, 3C1 and horizontal protrusions 3d, 3e of the plastic plate 3 on the other side to 2C, 2d, 2e, 2f, they are welded using high frequency or ultrasonic waves, making it even more robust. It is firmly fixed and can be used safely for many years.

2. In the present invention, a shallow groove 2b is formed in the plastic plate 2, and the handle rod 1 is provided in the shallow groove 2b.
Since the metal handle rod 1 is not provided up to the handle end of the metal western tableware a, the length of the handle rod 1 may be short, and therefore a lightweight handle of the western tableware a can be provided.

That is, in the conventional one, the metal handle rod 11 is provided up to the end of the handle, but in the one of the present invention, it is even lighter,
It has excellent features that make it easy to handle.

3. In the conventional model, both sides of the handle rod 11 were visible, but in the present invention, the handle rod 1 is provided in the shallow groove 2b, and the handle rod 1 is moved between the pair of plastic plates 2 and 3 using high frequency or ultrasonic waves. Since the handle is clamped and welded with the handle, the handle of the metal Western tableware a is provided with a beautiful handle in which the handle rod 1 is not visible.

4. Since the shallow groove 2b is formed in the plastic plate 2, the handle rod 1 is provided in the groove 2b, and the plastic plate 3 is welded by high frequency or ultrasonic waves, the entire handle rod 1 is made of plastic 2,
3, thereby providing metal Western tableware a that is more robust than conventional ones.

5. Decoration 4 is applied to the surface of the plastic plates 2 and 3 by heat transfer, film molding, hot stamping, etc.
A beautiful pattern of the metal western tableware a can be provided by the metal part of the handle rod 1, the plastic part of the plastic plates 2 and 3, and the decoration 4.
