Description

[Detailed Description of the Invention] The present invention relates to a handle with a bar screw whose handle body can be used in two types.

Conventionally, as a means of attaching a handle to a door of furniture, etc., as shown in Fig. 7, the bar screw of the handle is inserted directly into the through hole of the door and fixed with a nut, or the internal threaded part is fixed. The threaded handle is placed in the through-hole at the end of the door, and a screw is inserted into the through-hole to secure it with a screw (countersunk screws are used for one plate).
In most cases, the directly attached rod screw is 3 mm in diameter,
It is often used as a handle for furniture such as chests of drawers. The reason why we set the diameter to 3 mm is that, as shown in Figure 7, after inserting a bar screw into the through-hole of a door with an appropriate thickness and tightening the nut, the tip of the bar screw protruding inside the door should be inserted. This is because the cutting process can be performed easily and quickly, and if the diameter is 3 mm, it can be made durable in terms of strength.
In addition, the inner diameter of the internal thread is 4 mm in most cases.
It is often used as a handle for cupboards, etc.
This has been going on in the furniture industry for over 10 years now. For this reason, in the furniture hardware industry, even though the handle itself is the same, two types of handles are manufactured: a handle with a bar screw directly attached and a handle with an internal thread.As these handles come in a wide variety of designs, they are difficult to manufacture. Not only that, but inventory management was also extremely difficult. Furthermore, since the rod screw of the handle that is directly attached to the rod screw is always protruding, the handle body is often damaged during handling during transportation, resulting in a defective product.

Therefore, in the present invention, the large-diameter threaded portion of a rod screw, which consists of a long small-diameter threaded portion and a short large-diameter threaded portion, is screwed into the large-diameter internal threaded portion provided at the mounting base of the handle body. By doing so, the handle body can be used for two types of things, and there is no need to directly attach the handle with a bar screw.
This not only simplifies production, but also simplifies inventory management, allows for inexpensive handles with bar screws, and eliminates the above-mentioned drawbacks by preventing damage to the handle body during handling during transportation. It is.

The structure will be explained with reference to the drawings.

1 is the handle body, which has a flat U-shape (Fig. 1,
(see Figure 2), a knob shape (see Figure 5), or a rod shape (not shown) or an appropriate shape,
It is made of metal, wood, synthetic resin, etc. At least one place on the handle body 1 (two places in Figures 1 and 2, one place in Figure 3)
A large-diameter internal threaded portion 2 is screwed onto the mounting base 1a of the mounting base 1a. The actual inner diameter of the large diameter internal threaded portion 2 is 4 mm. In the case of the handle main body 1 made of metal, the large diameter internal threaded portion 2 is directly screwed into the member. In some cases, even if the member is made of synthetic resin, the large-diameter internal threaded portion 2 may be directly screwed into the member. Furthermore, in the case of most handle bodies 1 made of wood or synthetic resin, an inserter 3 having a large-diameter internal thread 2 screwed therein is embedded in a hole in a mounting base 1a of the same member. Reference numeral 4 is a bar screw, and a long small diameter threaded portion 4a and a short large diameter threaded portion 4b are continuously formed in the axial direction. Actual small diameter screw part 4a
The outer diameter of the large diameter screw portion 4b is 3 mm, and the outer diameter of the large diameter threaded portion 4b is 4 mm. The large-diameter threaded portion 4b of the rod screw 4 is configured to be appropriately screwed into the large-diameter internal threaded portion 2 of the handle main body 1. A flange portion 4c is often provided at the inner end of the large diameter threaded portion 4b (dotted line in Figure 2).
(See dotted line position in Figure 5). In the figure, reference numeral 5 indicates a countersunk screw, and the threaded portion thereof is configured to be appropriately screwed into the large-diameter internal threaded portion 2. 6 is a door of furniture, etc., and 7 is a nut.

Next, the effects will be explained.

In the present invention, the mounting base 1a of the handle body 1
By appropriately screwing the large-diameter threaded portion 4a of the bar screw 4, which consists of a long small-diameter threaded portion 4a and a short large-diameter threaded portion 4b, into the large-diameter internal threaded portion 2 provided in the 1. The handle body 1 can be used for two types of things, 2. Manufacturing is simple, 3. Inventory management is extremely simple, and 4. A handle with a bar screw can be provided at low cost. be effective.

To explain the function and effect in detail, first, the rod screw 4 consisting of a long small-diameter threaded portion 4a and a short large-diameter threaded portion 4b as in the present invention is suitable for furniture such as chest of drawers. It can be used as a handle for furniture such as a cupboard (see Figure 6), and if the handle body 1 is provided with a plate screw 5, it can be used as a handle for furniture such as a cupboard (see Figure 6). It can be well suited for the purpose of use in the furniture industry such as cupboards, etc. By doing this, there is no need for a conventional handle that is directly attached with a bar screw, and it is possible to prevent the handle body 1 from being damaged during transportation or other handling. It can be used for two types of applications in the furniture industry, such as furniture and cupboards, etc., and even by simple calculation, the number of copies in stock can be reduced to about half of the conventional one, making inventory management much easier. This is a creative idea. moreover,
By eliminating the need for a handle that is directly attached to the bar screw, the relatively troublesome manufacturing process is eliminated, and the handle body 1 and the bar screw 4 are no longer required.
Alternatively, it may be configured with a countersunk screw 5 as required, and the manufacturing becomes extremely simple, and as a result, an inexpensive handle with a bar screw 4 can be provided.
