Description

[Detailed description of the invention] The present invention relates to a pressure welding jig for wood, etc., which is used when joining pieces of wood together in woodworking, for example, and its purpose is to make it easy to use and to be able to strongly press pieces of wood together. shall be.

Conventionally, when joining pieces of wood together, a jig has been proposed that presses the pieces of wood so that the joining surfaces come closer together in order to strongly bond the pieces. When joining another piece of wood at right angles to the wood, members are provided at both ends of a long rod that spans the entire length of the one piece of wood, and the long rod is attached to the side of the piece of wood. It was a very labor-intensive task to operate the member while supporting it parallel to the side.

This invention was made to deal with such problems,
A member that is approximately T-shaped and has two mutually orthogonal through holes at its central tip, and an abbreviated member that is inserted at one end into one of the through holes of this member and has one clamping portion at the other end. , has a through hole at one end of the arm that can be inserted and removed from one end side of this abbreviated member, and an operating threaded rod is screwed into the other end of the arm, and the tip of the operating threaded rod is opposed to the one clamping portion. a member having the other clamping part constituting a pair of clamping part means, and a rod that can be freely fitted into and removed from the other through hole of the approximately T-shaped member, and a pressing force is applied in a direction parallel to the rod. The structure is such that a pressing means for applying the pressure can be attached to the rod.

The present invention will be explained below based on drawings showing an example of implementation.

In the figure, 1 is a member that is approximately T-shaped and has two through holes 2 and 3 that are orthogonal to each other at the central tip, and 4 is a member that has one end inserted into one through hole 2 of this approximately T-shaped member 1 and the other end. A member 6 is in the shape of an abbreviation with one holding part 5, and a through hole 7 in one end of the arm 8, which can be inserted and removed from one end of the member 4 in the abbreviation 4, is provided with an operating screw at the other end of the arm 8. A member 11 into which a rod 9 is screwed, and the other clamping part 10, which is opposite to the one clamping part 5 and constitutes a pair of clamping means, is provided at the tip of the operating threaded rod 9;
is a rod that can be fitted into and removed from the other through hole 3 of the substantially T-shaped member 1.

Reference numeral 12 denotes an arm having a through hole 13 at one end, into which the rod 11 can be inserted and removed, and the arm 12 at the other end.
The operating threaded rod 14 is screwed in the direction perpendicular to 2.

Reference numeral 15 denotes a pressing portion provided at the tip of the operating screw rod 14, and this pressing portion 15 is connected to the substantially T-shaped member 1 as shown in FIG.
Abuts on the outer surface of the central part.

As shown in FIG. 4, 16 is formed in a direction perpendicular to the through hole 17 in which the rod 11 is inserted, and a long rod 18 other than the rod 11 is inserted therein. This is a connecting member in which a groove portion 19 is formed.

As shown in FIG. 4, 20 is a connecting member connected to the elongated rod 18, and an operating threaded rod screwed into 21. This operating threaded rod 20 is attached in a direction perpendicular to the rod 18. .

22 is a pressing portion provided at the tip of the operating screw rod 20.

Note that 23 is a groove formed in the connecting member 21, and the rod 18 is fitted into the groove 23.

24 are tightening screws provided on the connecting members 16, 21 for fixing the connecting member 16 to the rod 11.degree. 18 and fixing the connecting member 21 to the rod 18.

Further, 25... are both prize through holes 2. of the substantially T-shaped member 1. '3
Tightening screws provided corresponding to the portions are used to fix the substantially T-shaped member 1, the substantially T-shaped member 4, and the rod 11 as necessary.

By the way, both the clamping parts 5 and 10 and the pressing parts 15 and 22 are constructed so that they can swing freely.

Next, a method of using the pressure welding jig for wood, etc. of the present invention will be explained.

First, as shown in FIG. 2, when joining the end surfaces of two pieces of wood 26 and 27 with adhesive, the approximately T-shaped member 1, the approximately T-shaped member 4, The arm 3 and the operating threaded rod 9 are attached, and the ends of each of the timbers 26 and 27 are clamped by clamping means from the clamping parts 5 and 10, respectively.

In this state, the arm 12 is fitted to one end of the rod 11, the operating screw rod 14 is rotated, and the tip pressing portion 15 is used to press the outer surface of the central portion of one approximately T-shaped member 1 to the other approximately T-shaped member. Press to the 1 side.

As a result, the T-shaped member 4 and the arm 8 attached to one T-shaped member 11 are pressed together, and the two pieces of wood 26 and 27 are pressed against each other and their end faces are strongly joined. Ru.

Also, as shown in FIG. 3, when another piece of wood 29 is joined to the end surface of the piece of wood 2B at right angles to this piece of wood 28 with an adhesive,
The substantially T-shaped member 1, the substantially T-shaped member 4, the arm 8, and the operating threaded rod 9 are attached to one location on the rod 11, and the ends of the wood 28 are clamped between the clamping parts 5 and 10.

Note that one end of the rod 11 is made to protrude toward another wood 29, and the arm of the pressing means 30 is attached to one end of the rod 11.

This pressing means 30 can use the arm 8 and the operating threaded rod 9, and the rod 11 is provided with the through hole 7 of the arm 8.
When fitted, the operating threaded rod 9 is oriented parallel to the rod 11, and its distal end clamping portion 10 can be opposed to the outer surface of the wood 29.

By tightening the operating rod 9 in this state, the wood 29 is pressed against the wood 28 side, and both wood pieces are held at 28°2.
9 is strongly bonded.

Furthermore, the one shown in Fig. 4 has the same purpose as Fig. 3, and uses wood 28
The rod 11 is clamped at both ends by the clamping parts 5 and 10, respectively.
, 11 protrudes toward another wood 29, and the connecting member 16.16 is attached to one end of the rods 11, 11, and the elongated rod 18 is hung between the connecting members 16.16. , Operation threaded rods 20 are attached to the rod 18 via connecting members 21 so as to be parallel to the rod 11 at appropriate intervals in the longitudinal direction of the rod 18 .

The wood 29 is evenly pressed against the wood 28 over its entire length by the plurality of operation threaded rods 20, and both wood 28.
29 can be strongly bonded.

By the way, in the above usage example, for example, the operation screw rod 9
When tightening the arm 8, one end of the arm 8 to which it is attached is only fitted into the oval-shaped member 4, so as it is tightened, the arm 8 seems to slide in the direction away from the oval-shaped member 4. However, since the inner surface of the through hole 7 at one end of the arm 8 and the outer surface of the abbreviated member 4 are pressed together in a slightly distorted state, the arm 8 does not slide and the tightening force of the operating screw rod 9 is ensured. can be transmitted to.

Further, the tightening screw 25 is used, for example, for positioning the abbreviated member 4 when one of the clamping portions 5 is brought into contact with the lower surface of the timbers 26, 27. It may be used for fixing the shaped member 1 and the rod 11 as needed.

Furthermore, in FIGS. 2 to 4, the operating threaded rod 14.9.
20, the tensile force (and pressing force) applied to the T-shaped member 1 is transmitted from three points on the T-shaped member 1 to the T-shaped member 4 and the arm 8, causing local damage. It can be prevented.

The wood pressure welding jig of the present invention can be used by appropriately rearranging it in addition to the usage examples shown in FIGS. 2 to 4.

In addition to pressure welding wood together, it can also be used to pressure weld metal together.

The present invention can be implemented as described above, is easy to use, and can strongly press wood or metal together.
In particular, since attachment is achieved at the end of the wood or the like near the joint, workability is improved compared to conventional ones.

Also, since it is compact, it is convenient to carry.
