Abstract

To provide an adapter for a wood screw which enables any user to screw a wood screw, ranging from a large size wood screw to a small size wood screw, into a member properly without inclining the wood screw downward and causing decentering.SOLUTION: In the invention, a body 1 of an adapter for a wood screw in which a screw is set is attached to a driver tip 14 to be used. The invention has a structure which can maintain integration of a driver shaft body 13 and a wood screw body 8 and enables the wood screw body 8 to be screwed into a member without causing decentering. Further, when or after the wood screw is screwed into the member, the body 1 of the adapter for the wood screw is removed from the wood screw.SELECTED DRAWING: Figure 1

Description

The present invention relates to a wood screw adapter.

With a conventional manual screwdriver or electric screwdriver, the tip of the bit and the wood screw are separated when screwing a wood screw into a component, so it is necessary to support the wood screw with one hand to prevent core wobble. rice field. The same thing could be said when the tip of the driver was a magnet.

In order to compensate for this drawback, it is necessary to have a structure that integrates the tip of the bit and the wood screw at the initial stage of the work and holds the wood screw so that the wood screw does not fall over and the core does not move. An adapter with a wood screw set is attached to the tip of the socket pushed out by the built-in elastic body arranged in the . Although it prevents core blurring, there are still problems in manufacturing cost, usability in use, and the number of manual actions.

Further, Patent Document 2 has the same purpose of integrating a driver bit and a wood screw by tightening a unit in which a socket portion pressed by an elastic body arranged on the driver shaft grips the wood screw from the periphery. Even so, there are still problems in manufacturing cost, usability in use, and the number of manual actions.

The problem with conventional manual screwdrivers and electric screwdrivers is that the meshing part between the tip of the screwdriver and the head of the wood screw is weak against lateral force, making it difficult to screw the screw into the member accurately without tipping over. there were. As a result, the screw falls down due to core deflection, and the member may be damaged, or the tip of the bit may poke the finger supporting the screw and injure the user. The same thing could be said when the tip of the bit is a magnet.

In order to solve this problem, the present invention provides an adapter for wood screws characterized by a structure in which the tip of the screwdriver and the screw are integrated to prevent core deflection and screw tilting.

The main body 1 of the wood screw adapter comprises a main body portion 2, a main body distal end portion 3, and a main body distal end tip 4, and a threaded portion 11 of a wood screw 8 extends from the main body distal end portion 3 inside 6 of the main body distal end portion. A screwdriver shaft 13 is inserted into a tool groove of a screwdriver tip 14 and a wood screw 8 in a main body 2 of the main body 1 which protrudes and is set so that the inside 6 of the tip of the main body wraps around the screw part 11 and the head 9 without a gap. The driver shaft 13, the tip 14 of the driver, and the wood screw 8 are integrated so as to wrap around each other by inserting the driver shaft 10 to the point where they mesh with each other, and the rotation shafts of the driver shaft 13 and the wood screw 8 are aligned to prevent core shake. A wood screw adapter characterized by a structure for screwing a wood screw 8 into a member 12.

When the wood screw 8 is screwed into the member 12 with the tip of the driver 14 engaged in the tool groove 10 of the head 9 of the wood screw 8, the inner diameter of the tip 4 of the tip of the main body touches the member 12, and then from the member 12. Due to the pressure applied to the tip 3 of the main body and the pressure from the inside by the head 9 of the wood screw 8, the tip 3 of the main body expands toward the main body 2 until it becomes equal to or larger than the outer diameter of the driver shaft 13. , and the main body 1 inserted into the driver shaft 13 slides from the driver tip 14 toward the driver shaft 13 by the pressure from the member 12, and when the wood screw head 9 reaches the member 12, the main body 1 The wood screw adapter is characterized by a structure in which the wood screw 8 is removed from the wood screw.

The inner side 5 of the main body portion has a cylindrical shape that wraps around the driver shaft 14, and the inner side 6 of the tip portion of the main body has a tapered shape that fits the shape from the head 9 to the screw portion 11 of the wood screw 8. The tip 3 of the main body has a structure that expands in diameter by pressure from the head 9 when the wood screw 8 is screwed in from the inside, and the protruding end 4 of the tip of the main body is connected to the member 12 when the wood screw 8 is screwed in. Friction resistance with the member 12 is reduced when the wood screw 8 comes into contact with the member 12, and before the head 9 of the wood screw 8 reaches the member 12, the head 9 of the wood screw 8 is prevented from biting the tip 4 of the tip of the main body. An adapter for wood screws, characterized in that:

The wood screw adapter of the present invention has a structure in which the driver and the wood screw are integrally held, so that the wood screw does not fall down due to wobbling of the core. Therefore, the operation of screwing wood screws into members can be made accurate and efficient regardless of experience. In addition, it can be used as both an electric screwdriver and a hand-cranked screwdriver, and has high versatility regardless of the shape of the screwdriver shaft.

The inside of the main body portion 2 has a cylindrical shape that can be adapted to the shape of the driver shaft 13, such as a column or a hexagonal column. The screwdriver tip 14 can be engaged with the tool groove 10 of the head 9 of the screwdriver, and when the wood screw 8 is screwed into the member 12, the screwdriver shaft 13 can be slid upward by the pressure from the member 12. Therefore, it takes a form having an inner diameter larger than the maximum diameter of the driver shaft 13 .

However, the wood screws 8 refer to pan screws or countersunk screws, and the members 12 refer to materials such as wood, laminated lumber, plywood, gypsum board, and synthetic resin.

Further, the above-mentioned "at the time of screwing" refers to a state in which the threaded portion 11 of the wood screw 8 is being screwed into the member 9. As shown in FIG.

The tip end portion 3 of the main body has a tapered shape in which the inside 6 of the tip end portion of the body is held from the head portion 9 to the screw portion 11 of the wood screw 8, and there is no protrusion inside the tip end portion 3 of the body, and the member 12 is touched. The tip 3 of the main body has a rounded form that reduces friction with the member 12 when the wood screw 8 is screwed into the member 12. - 特許庁

When the wood screw body 8 is screwed into the member 12, after the tip 4 of the body tip touches the member 12, the body tip 3 receives pressure from the member 12 and the inside of the head 9 of the wood screw 8. Although the body distal end portion 3 is provided with a structure in which the body distal end portion 3 expands in diameter by the pressure that pushes the body distal end portion 3 open, the distal end portion 3 expands or collapses due to the same pressure by a plurality of cuts 7, or the body distal end portion 3 Refers to a structure in which the inner diameter opens while the length of the is shortened.

The main body 1, the main body portion 2, the main body tip portion 3, and the main body tip tip 4 are made of synthetic resin, paper, wood, laminated wood, or the like.

When the inner diameter of the body portion 2 exceeds the maximum diameter of the driver shaft 13, a cylindrical adapter 15 is mounted between the driver shaft 13 and the main body 1. As shown in FIG.

The maximum diameter of the driver shaft 12 means the diameter when the shape of the wood screw adapter is cylindrical, and the diameter of the circumscribed circle when the driver shaft 12 is prismatic.

The tip 14 of the driver bites into the tool groove 10 of the head 9 of the wood screw 8, the tip 3 of the main body holds the screw head 9 and the wood screw 8, and the body 2 of the main body includes the shaft 13 of the driver. , the wood screw 8 and the driver shaft 13 are integrated.

The wood screw adapter of the present invention has several sizes depending on the size and shape of the wood screw 8 .
