Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving position adjuster that is used by being attached to a pneumatic impact tool.

In general, so-called pneumatic impact tools are widely used for fixing architectural board materials such as interior materials and floorboards of houses with nails, etc.
In the case of floorboard materials, if the heads of nails or the like are exposed on the surface, the appearance quality will be greatly impaired.

Therefore, in the installation work of floorboard materials, etc., conventionally, as shown in FIG. A method is adopted in which nails 5 and the like are driven and fixed using a tool 4. Generally, the pneumatic impact tool 4 has an internal impact cylinder, an impact piston, and a driver integrally formed below the impact piston, and drives a nail or the like into a workpiece by opening and closing a trigger valve. It is configured to fit in.

However, in such conventional installation work, it is not possible to hold the nose portion 6 of the pneumatic impact tool 4 on the driving surface 2 of the floorboard material 1, etc., so it is difficult to hold the tool at an appropriate driving position. It is difficult to do so, and there have been problems such as cases in which the floorboard material 1 etc. cannot be properly fixed to the waste board 3.

This invention was devised in view of the above-mentioned conventional problems, and its purpose is to use a pneumatic impact tool when fixing a member to be adhered to, such as a floorboard, using a pneumatic impact tool. An object of the present invention is to provide a driving position adjuster for a pneumatic impact tool that can hold the nose portion of a pneumatic impact tool at a proper driving position with respect to the driving surface of a member to be adhered.

The gist of the present invention is that the first contact member is mounted at the bottom of the pneumatic impact tool so that its mounting position can be moved in the front and back direction, and that contacts a reference plane that is substantially perpendicular to the driving surface of the adhered member. and a second contact member provided at the lower part of the pneumatic impact tool and abuts on the driving surface, and the nose portion of the pneumatic impact tool is driven by the contact of the first and second contact members. A pneumatic impact tool is provided in which the driving position of the nose portion can be adjusted by holding the nose portion in place and moving the mounting position of the first abutting member.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 2 shows a case in which the driving position adjuster 7 according to the present invention is attached to a pneumatic impact tool 4 having the same structure as the conventional one, and is used to fix a floor board material 1 placed on the upper surface of a scrap board 3. It shows the condition.

The driving position adjusting tool 7 according to this embodiment is composed of a first abutting member 7a and a second abutting member 7b. The first abutting member 7a includes a flat base 9 mounted on the lower frame 8 of the pneumatic impact tool 4 so that its mounting position can be moved in the front-back direction;
It is integrally formed through this base part 9 and the connecting part 10, and the side surface of the floorboard material 1 is used as the driving surface 2.
The reference plane 11 is a plane substantially orthogonal to the reference plane 1.
A triangular frame structure is constituted by a plate-shaped holding part 12 that abuts on the holding part 12 and holds the driving position of the nose part 6 at an angle of about 45 degrees. Further, the second contact member 7b includes a mounting plate 14 fixed to the lower surface of the lower frame 8 and a contact protrusion 14a protruding from the front end of the mounting plate 14 and contacting the driving surface 2. ing. A long hole 13 is opened in the base 9 along the longitudinal direction, and the base 9 is slid as appropriate along the longitudinal direction of a mounting plate 14 fixed to the lower surface of the frame 8. By fixing with a screw 16 into a screw hole 15 provided in the nail 1, the driving position (the driving location and driving angle) of the nail 5 relative to the floorboard material 1 can be adjusted.

Therefore, as shown in FIG. 3, even when arranging and fixing floorboard materials 1' having different thicknesses, the air pressure can be adjusted by appropriately adjusting the first contact member 7a of the driving position adjustment tool 7. The nose portion 6 of the type impact tool 4 can be secured at an appropriate driving position.

Next, the case of fixing the floorboard material 1 using the pneumatic impact tool 4 equipped with the driving position adjuster 7 having the above configuration will be explained based on FIG. 2. First, the second abutting member The abutting protrusion 14a of 7b is brought into contact with the driving surface 2 of the floorboard material 1, and the floorboard material 1
The holding part 12 of the first abutting member 7a of the driving position adjustment tool 7 is brought into contact with the reference surface 11 of the screw 16.
, slide the pneumatic impact tool 4 along the elongated hole 13 of the base 9, and align the tip of the nose portion 6 with the proper driving position. Next, tighten the screws 16 to tighten the lower frame 8 of the pneumatic impact tool 4.
After fixing the first abutting member 7a of the driving position adjustment tool 7, the nail 5 and the like are driven. In this case, movement in the direction of the driving surface 2 is regulated by the holding portion 12 of the first abutting member 7a, and movement in the direction of the reference surface 11 is regulated by the second abutting member 7b. For this reason,
In the pneumatic impact tool 4, the driving angle and driving location are held constant by the driving position adjuster 7, so that the nail 5 can be properly driven into the floorboard material 1, and the floorboard material 1 can be properly driven. It is properly fixed to the waste board 3.

FIG. 4 shows an example of application of the driving position adjuster 7 according to the present invention, in which the driving position adjusting tool 7 according to the present invention is used in combination with a guide member 17 arranged and fixed on the front surface of the nose portion 6 to adjust the driving position of the pneumatic impact tool 4. This makes it possible to secure the insertion position even more reliably.

That is, the guide member 17 is connected to the driving surface 2 of the floorboard material 1.
It has a recess 19 at its tip as an engaging part that fits into a connecting convex part 18 formed protruding from the top of the driving position adjusting tool 7 that comes into contact with the reference surface 11 of the floorboard material 1. The holding part 12 of the first contact member 7a and the second contact member 7b that contacts the driving surface 2 of the floorboard material 1
The abutting protrusion 14a and the recess 1 that fits into the protrusion 18
9, the pneumatic impact tool 4 is reliably held in its driving position. Note that the engaging portion of the guide member 17 is not limited to the shape of the recess 19;
Of course, the shape can be changed as appropriate depending on the shape of the engaged portion on the floorboard material 1 side.

FIG. 5 shows another embodiment of the driving position adjusting tool 7' according to the present invention, which can be used when installing a suitable plate material 21 on a foundation wall 20.

That is, the driving position adjusting tool 7' in this embodiment
is composed of a first abutting member 7'a and a second abutting member 7'b constructed in the same manner as described above. The first contact member 7'a includes a base 9' that is fixed to the lower frame 8 of the pneumatic impact tool 4 via the mounting plate 14 and contacts the driving surface 21a, and a side reference surface 11' of the plate material 21. approximately L with the holding part 12' in contact with the
As in the previous embodiment, the periphery of the elongated hole 13 bored along the longitudinal direction of the base 9' allows the screw 16 inserted into the screw hole 15 provided in the mounting plate 14 to be tightened. It is placed in a predetermined position by being fixed by attaching it. The head of the screw 16 is hidden in a groove 22 formed in the base 9' so that it does not get in the way when the surface of the base 9' and the plate 21 come into contact.

In this embodiment, by displacing the holding portion 12' in the horizontal direction along the reference plane 11', the nails 5 driven from the nose portion 6 are aligned substantially horizontally, which is preferable in terms of appearance quality. Further, when it is desired to shift the driving position in the vertical direction, the driving position can be easily adjusted by sliding the base 9' along the frame 8 and fixing it at a predetermined position with the screw 16. Also, in this example,
Not only the second abutting portion 7'b but also the base 9' are connected to the driving surface 2.
Since it comes into contact with 1a, the nose portion 6 can be held more reliably. In this embodiment, since the base 9' abuts the driving surface 21a, the second abutting member 7'
The base portion 9' may be configured as a second abutting member without specifically providing b.

In the above embodiment, the triangular shape and the L
Although the driving position adjusting tools 7 and 7' in the shape of a letter have been described, the present invention is not limited to the above shapes, and may be of any suitable shape and size depending on the shape of the member to be adhered, the state of attachment, etc. It can be configured as follows.

Since the present invention is constructed as described above, it is possible to easily hold the nose portion of the pneumatic impact tool in the proper driving position when driving a nail or the like from the side or front side of a member to be fastened. This makes it possible to accurately drive nails, etc.
It is particularly useful when driving nails etc. into the side surfaces of floorboards of different thicknesses. Note that the same effect is achieved not only in driving nails but also in driving staples.
