Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention assembles log materials by a piece-end-piece construction method, a post-beam construction method, or a frame construction method or a round notch construction method to construct a building commonly called a log house and other constructions. The present invention relates to a new scriber, which is an essential black-and-white attachment tool.

[0002]

2. Description of the Related Art Conventionally, a scriber having a large-sized compass and a spirit level has been used for marking black logs. In this scriber, for example, one log is placed horizontally, the other log is placed on top of it, and the scribe is kept vertical, and the tips of the two compasses are placed on the circumferential side surfaces of both logs. It is a tool for marking, i.e., scribing, the peripheral side surfaces of both the lower log material and the upper log material on the peripheral side surfaces of the lower log material while simultaneously applying them.

The conventional scriber is a simple tool and is widely used in construction sites. However, for example, one log is placed horizontally and the other log is placed with a space above it. When scribing is performed in parallel, obliquely or at right angles to one of the logs, the conventional scriber cannot scribe around the circumferential side of the log and can scribe only a part of the circumferential side. Further, in the conventional scriber, there is a problem that it is a patience work to scribe while keeping the scriber vertical on the peripheral side surfaces of two logs having a complicated curved surface. Further, there is a problem that skill is required to scribe accurately.

In view of the problems of the conventional scriber, the inventor has developed a swing type scriber that relatively easily marks the peripheral side surfaces of a pair of logs, and proposes this in Japanese Patent Application No. Proposed by No. 95962. This swing type scriber includes, for example, a support structure and a plurality of swing members,
A plurality of rocking members are pivotally connected to each other in a pivotable manner, the base end of which is pivotally connected to a support structure, and a slide rod at the tip of the rocking member is pivotable about a vertical axis and vertically movable. The slide rod is movably provided with a pair of marking members provided with a writing instrument. With this configuration, it is possible to freely move the slide rod provided with the marking member in a wide range around the support structure while always keeping the slide rod vertically.
For example, it was possible to accurately scribe the peripheral side surfaces of the logs placed above and below each other.

[0005]

The swing type scriber has an integral structure in which a slide rod is vertically provided by a support structure and a plurality of swing members. Therefore, for example, it is suitable for accurately scribing a log material in a log house kit manufacturing plant or for scribing for constructing a connection structure such as a large diameter pipe. However, there is a problem in that it is structurally large and cannot be easily carried to a construction site.

[0006] Further, in recent years, the construction of log houses has spread worldwide, and since the spread of log houses is in full swing in Japan as well, they are easy to carry, can be conveniently used on the construction site, and can be used for logs. There has been a problem that an economical scriber that can accurately redact wood is desired.

Since the present invention solves the above problems and problems, it is convenient to carry and can be easily used.
An object of the present invention is to economically provide a new scriber that can accurately mark logs and a mounting table for the scriber.

[0008]

The scriber of the present invention comprises:
In order to achieve the above object, a free slider that is placed on a horizontal mounting table and that can freely move is provided, and a slide rod that is vertically movable while maintaining a right angle to the free slider is provided. A pair of marking members provided with a writing instrument are provided on the slide rod so as to be vertically movable. The free slider is provided with a pivot portion that allows the slide rod to rotate. The pair of marking members is provided with a writing instrument that can be rotated by a declination angle. The free slider, slide rod and marking member can be assembled and disassembled. Further, the mounting table for the scriber of the present invention,
It is characterized by comprising a rectangular frame and legs provided at the corners of the frame, and sliding bars are mounted on the frame. The leg length may be adjustable.

DETAILED DESCRIPTION OF THE INVENTION The scriber of the present invention will be described with reference to FIGS. A slide rod 1 is mounted at right angle on a horizontal free slider 2 which can be freely slid on a horizontal mounting table, which will be described later, through a vertical guide portion 3, and the slide rod 1 is vertically moved on the vertical guide portion 3. It is inserted freely. As a result, it is possible to guide the slide rod 1 vertically while the free slider 2 is in the horizontal state while the slide rod 1 is kept vertical.
A pair of marking members 4 and 4 are provided so as to be vertically movable. The slide rod 1 is formed of a long rectangular member, and has vertical grooves 6, 6 on its front and back surfaces and a vertical groove 10 opened along a side surface 7. The vertical groove 10 is widened inside the slide rod 1. The free slider 2 is formed of a long and wide plate member 8, a vertical guide portion 3 provided at the base end of the plate member 8, and a balance plate 9 at the tip.

At the base end of the plate member 8, a mounting plate 11 formed of a thick plate member is vertically provided. Guide members 13, 13 with inward locking pieces 12 are provided opposite to each other on the upper and lower portions of the slightly vertically long mounting plate 11, and rotatably provided on the inside of each of the guide members 13. Balls 14, 1
4 is inserted into the vertical grooves 6, 6 of the slide rod 1 to vertically guide the slide rod 1 inserted therein vertically and vertically, thereby forming the vertical guide portion 3. Instead of the balls for bearings, the slide rod may be vertically guided by a guide rod made of, for example, a plastic material. Further, a level may be provided on the slide rod or the free slider. The slide rod 1 is assembled into the guide member 13 so that it can be disassembled and is assembled so that it can be disassembled when carried and assembled on site.

The above-mentioned marking members 4 and 4 are in contact with the side surface 7 of the slide rod 1 and are a slightly vertical cross-shaped square member 15 and 15.
Through the opening of the side surface 7, and its base end is fixed to the central portion of the slider 17 loosely inserted in the vertical groove 10 (FIG. 3). The screws 16 fixed to the upper part and the lower part of the slider 17 protrude from the opening of the side surface 7,
The cross-shaped square member 15 is penetrated, and wing nuts 18, 18 are screwed into the extra length portion. The wing nut 18 allows the pair of marking members 4 and 4 to move up and down on the slide rod 1 and fix their positions. Each of the marking members 4 and 4 is formed of a rectangular tubular body, and lateral grooves 19 and 19 are provided on the front surface and the back surface thereof. The lateral groove 19 and the screw 20 adjust the position of the writing instrument 5, and the screw 21 adjusts the vertical angle and length of the writing instrument 5. The marking members 4 and 4 are also incorporated in the slide rod 1 so that they can be assembled and disassembled so that they can be disassembled when carrying and assembled on site.

FIG. 4 shows a scriber having the above-described structure and a mounting table 4 on which the free slider 2 of the scriber is mounted.
1 indicates a state in which the log 42 and the log 43 are scribed. In the figure, the log 42 is the horizontal core ink 44,
A plane including 44 is arranged horizontally, and a log 43 is arranged below the log 42 with a slight interval. The core of the log 43 is at a right angle to the core of the log 42, and the plane including the horizontal core inks 47, 47 is horizontal. A plane including the upper core ink 45 and the lower core ink 46 of the log material 42 and a plane including the upper core ink 48 and the lower core ink 49 of the log material 43 are vertical.

The mounting table 41 has a rectangular frame 5
0 and four legs 54 of variable length provided at the corners of the frame 50.
Sliding rods 51 made of a hard plastic material are mounted on the four frame members forming 0. This slide bar 51
The free slider 2 mounted on the frame 50 is slidably moved. The mounting table 41 has a level attached to the frame 50, and the mounting table 41 is made horizontal by adjusting the length of the legs 54. As shown in FIG. 4, two of the above four legs are placed on the log 42, the other two are placed on the log 43, and the mounting table 41 is horizontally arranged above the log. I am doing it.
The free slider 2 of the scriber is slidably mounted on the frame 50. The free slider 2 vertically moves the slide rod 1 around the frame 50 and guides it vertically so that the tip of the writing instrument 5 provided on the pair of marking members 4 and 4 is attached to the log 42 and the log 42. It can be moved freely around the circumference of 43. The mounting table is not limited to the one described above. Anything can be used as long as it can be stably attached while keeping the horizontal position.

Next, the work of scribing using the scriber of the present invention will be described. First, it is necessary to determine the position of the tip of the writing instrument 5 of the marking member with respect to the slide rod 1 in the vertical state. That is, the distances of the tip positions of the respective writing tools 5 from the slide rod 1 are matched so that the lines connecting the tips of the respective writing tools 5 of the upper and lower marking members are vertical. At the same time, match the distance between the tips of the upper and lower writing instruments 5 with the distance between the cores of the upper and lower logs 42, 43,
The upper and lower marking members 5 are positioned. After that,
The free slider 2 is slid and moved while being placed on the frame frame 49 of the mounting table 41, and the slide rod 1 is operated while the tips of the writing instruments 5 and 5 are simultaneously applied to the peripheral side surfaces of the logs 24 and 25. , The upper half of the peripheral side surfaces of the logs 42 and 43 are scribed. Also, when scribing on the opposite peripheral side surface, the free slider and the slide rod may be moved to the opposite side.

Next, when scribing on the lower half surface of the peripheral side surface of the log material, the screws 20 and the like are loosened, and the tips of the writing instruments 5 on both marking members are changed upward. After making this change, the positioning operation of the marking member is repeated again. After completing this operation, scribe is restarted.
With the above procedure, for example, at a construction site, a work of scribing the peripheral side surfaces of a pair of logs arranged vertically using a jack or a stepladder can be performed. Further, this scribe can be formed on a part of the peripheral side surface or along the entire circumference.

Another embodiment will be described below with reference to FIGS. Free slider 24 placed horizontally in FIG.
A scriber is formed by vertically inserting the above-mentioned slide rod 1 into the vertical guide portion 3 so as to be vertically movable. The vertical guide portion 3 can be horizontally rotated by a pivot portion 25 described later. The free slider 24 includes a long and wide plate member 26, a cross beam 27 provided at the base end portion of the plate member 26, a stop plate 28 slightly protruding below the front end, and the cross beam 27 and the stop plate 28. Overhanging material 29, 2 laid across
9 and the above-mentioned pivotal support portion 25 and vertical guide portion 3. At the base end of the plate member 26, a horizontal portion of the support member 30 formed of a thick plate member in a T shape is detachably attached by a screw or the like, and its vertical portion is provided in contact with the base end of the plate member 26. A rotary shaft 31 is passed through a vertical portion of the support member 30, and the rotary shaft 31 interposes a pair of upper and lower small arms 32 to allow the mounting plate 11 of the vertical guide portion 3 to be horizontally rotatable. It is pivotally supported to form a pivot 25. As a result, the slide rod 1 can be horizontally rotated within the range of the arrow shown in FIG.

FIG. 7 shows a state in which the scriber having the above-described structure and the mounting table 52 on which the free slider 24 of the scriber is mounted scribes on the logs 42 and 43. The mounting table 52 includes a rectangular frame 50 and four legs 5 of the same length provided on the frame 50.
4 and the sliding rod 51 is mounted on the parallel long sides of the frame 50. Leg 5 above
The lateral width between the four and the leg 54 is also variable, so that the two legs 54 are slidable with respect to the frame. Pins 55 are provided at the lower ends of the four legs 54, the pins 55 are driven into the horizontal core inks 44, 44 of the log 42, and the mounting table 52 is horizontally attached to the upper part of the log 42.
Therefore, the free slider 24 of the scriber is placed on the parallel long sides. Since the free slider 24 guides the slide rod 1 so as to be vertically vertically movable and horizontally pivots within the range shown in FIG. 7,
With the slide rod 1 kept vertical, the pair of marking members 4, 4 can be horizontally swung to freely move around the circumferential side surfaces of the logs 42 and 43. In this state, the log 42 and the log 43 are produced according to the procedure described above.
And you can scribe a part of each side of each other,
You can also scribe along the entire circumference.
