Description

  The present invention relates to a connecting device for wooden members capable of firmly connecting two wooden members.

JP 2002-4497 A

  Conventionally, as a method of connecting two wooden members, a method of connecting or joining both members using a nail with sharp ends is already known as described in JP-A-2002-4497.

  In this method, there is a gap of the thickness of the plate provided with nails with both ends sharp, so that the appearance is not impaired without being visible from the outside when joining the planes, but the gap is visible when joining the end faces Sometimes it looks bad.

For example, in the case of a wooden headquarters with the function of providing a door pocket that is a storage part for a sliding door, the groove where the upper end of the sliding door fits must always be on the lower surface side, so the position where the door pocket is provided when viewed from the indoor side is Therefore, it was necessary to make it a planar L-shaped shape so that a wide part and a narrow part of the Kamoi could be formed.

  Therefore, conventionally, the rectangular mooring material with a groove that fits the upper end of the sliding door on the lower surface can be cut into a flat L-shape that can form a wide part and a narrow part depending on the position where the door is provided at the construction site. Was.

Object of the invention

  The present invention is a knock-down type headquarters that can be freely changed at the construction site regardless of whether the door is provided on the right side or the left side by changing the mounting position of another head member on the narrow head member. It is related with the connection apparatus of the wooden member which can comprise.

Means for solving the problem

  The connecting device for a wooden member according to the present invention fixes a screw having a head to one wooden member, and a recess formed in the other wooden member has a round hole into which the head of the screw can be inserted, A connecting tool formed of a synthetic resin in which a long hole having a diameter narrower than the diameter of the round hole continuing to the round hole is fitted, and the head of the screw fixed to the one wooden member is connected to the connecting member. By sliding the other wooden member in a state of being fitted into the round hole, the side wall of the elongated hole is expanded with the head of the screw to expand the connection tool, and the connection tool is brought into close contact with the side wall of the recess. It is characterized by connecting the members.

Effect of the invention

  The connecting device for a wooden member according to the present invention includes a screw and a screw of one wooden member which are expanded by a connecting tool in which a head of a screw fixed to one wooden member is fitted in a recess formed in the other wooden member. These wooden members are integrated and firmly connected via a connector.

FIG. 5 is a perspective view of a screw, FIG. 6 is a perspective view showing a state in which two wooden members are connected, and FIGS. 7 and 8 show a relationship between the connector and the screw. FIG. 9 is a perspective view of another embodiment of the connector, FIG. 10 is a plan view of the connector of FIG. 9, FIG. 11 is a cross-sectional detail view of the connector connected by the connector, and FIG. It is a perspective view showing the case of the wooden duck with the function which provides the door pocket which is a storage part of the sliding door by this invention apparatus.

  In the figure, reference numeral 1 denotes a connector fitted in a recess of one wooden member constituting the device of the present invention, which is formed of a synthetic resin and is operated by the action of a screw head fixed to the other wooden member described later. It expands and bites into the concave side wall of the wooden member, so that the two wooden members are connected to the connector 1 via screws.

  The specific structure of the connector 1 is as follows. The side wall 2-1 has a large number of projections 2c... 2c formed below both sides of the substrate 2 continuously drilled with a large diameter hole 2a and a small diameter long hole 2b. 2, and is used by being fitted into a recess h that is substantially the same shape as the planar shape of the connector 1 formed on the end surface of one wooden member A.

  3 is a screw provided with a flange 3-1 for restricting the amount of protrusion, and after fastening to the other wooden member B, the head 3-2 of the screw 3 is inserted into the large-diameter hole 2 a of the connector 2. It is configured to be inserted into.

  In FIG. 12, the wooden members A and B are called Kamoi constituents.

Next, a method for connecting wooden members by the apparatus of the present invention will be described. First, a plurality of recesses h in which the connector 1 can be fitted to the side end surface of the wooden member A, which is one of the kamoi structures, are provided at predetermined positions. The head 3-1 of the screw 3 attached to the side end surface of the other wooden member B corresponding to the recess h is fitted into the large-diameter hole 2 a of the connector 1, and the wooden member B is When the head 3-1 of the screw 3 is moved from the position of the large-diameter hole 2 a to the small-diameter long hole 2 b by sliding to the right, both side walls 2-1 and 2-1 of the substrate 2 spread outward. The protrusion 2c bites into the side wall of the recess h, and the wooden members A and B are firmly connected.

  In the case of the connector 1 in FIG. 9, if the semicircular protrusions 2 d and 2 d are fitted in the holes D formed in the wooden member A on the both side walls 2-1 and 2-1 of the substrate 2, A strong connection is obtained.

  In this way, by changing the mounting position of the narrow head portion and the wide head portion as shown in FIG. 12, the knock can be freely changed at the construction site regardless of whether the door is provided on the right side or the left side. A down-type duck can be constructed.

Effect of the invention

  According to the connecting device of the wooden member according to the present invention, the screw of one wooden member is expanded by extending the connecting tool in which the head of the screw fixed to the one wooden member is fitted into the recess formed in the other wooden member. And the other wooden member is integrated and firmly connected via a connector, so that the connection state deteriorates due to aging effects such as adhesives and so on, and no unexpected accidents occur, For example, by changing the mounting position of another moss material to a narrow sword material, a knock-down stool can be freely changed at the construction site regardless of whether the door is provided on the right side or the left side. It is something that can be done.

  In addition, it is possible to omit the protrusions that bite into the side wall of the recess by molding the connector with a synthetic resin having a very high coefficient of friction and making the degree of adhesion between the side wall of the fitting recess of the connector and the connector extremely high. .
