Description

The present invention relates to a pipe joint member that holds a vertical pipe in the vertical direction and holds a horizontal pipe in the horizontal direction.

Traditionally, metal pipe materials, etc. have been used as vertical pipes (hereinafter sometimes referred to as "vertical pipes") and horizontal pipes (hereinafter sometimes referred to as "horizontal pipes"). In some cases, these were connected via pipe joint members and used as frameworks for various types of fences and fences.

As a related technology, there is a technology that provides a pipe joint that connects pipes of various shapes such as square pipes and round pipes so that they intersect at a desired angle when assembling them into a desired member. (See Patent Document 1).

In addition, as a related technique, by forming a convex strip extending in the longitudinal direction of the pipe material on the outer circumferential surface of the cylindrical part, the section modulus of the part is increased, and the strength of the cylindrical part is improved. There is a technology that provides a pipe joint with excellent strength by reducing the possibility that the vicinity of the opening ends of the split joint will deform in the direction of separating from each other, so that the pipe material can be continuously and strongly gripped (see Patent Document 2). .

In addition, as a related technology, there is a technology that provides a pipe joint fitting that allows a hanging pipe to be easily and effortlessly removed from a pipe-type clothes rack or the like (see Patent Document 3).

Embodiments of the present invention will be described below with reference to the drawings.
FIGS. 1 to 3 collectively show the external structure of a pipe joint member (band portions and the like are partially omitted) according to an embodiment of the present invention.
Each component of the pipe joint member 1 is made of metal unless otherwise specified below, but may be made of resin or the like.
Note that the pipe joint member 1 ultimately holds the vertical pipe 2 in the vertical direction and holds the horizontal pipe 3 in the horizontal direction.

The pipe joint member 1 mainly includes a first clamping part 10 and a second clamping part 20.
These first clamping part 10 and second clamping part 20 are connected via a hinge part 30, and can be in an "open state" (hereinafter sometimes simply referred to as "open state") and a "closed state". state (hereinafter sometimes simply referred to as "closed state").
The pipe joint member 1 is finally fastened by the bolt mechanism part 60 and the nut part 70 in the "closed state" to hold the vertical pipe 2 in the vertical direction and the horizontal pipe 3 in the horizontal direction. becomes.

The first holding part 10 includes a first vertical pipe holding part 11 and a first horizontal pipe holding part 12.
The first vertical pipe holding part 11 has a generally cylindrical shape that is vertically divided into two parts and placed vertically, and together with the second vertical pipe holding part 21 of the second holding part 20 described later. Finally, the vertical pipe 2 is held in the "closed state".
Further, a nut hole 111 for the nut portion 70 is formed in the first vertical pipe holding portion 11 . Note that a nut part 70 is attached to the outer wall surface side of the first vertical pipe holding part 11 so as to communicate with the nut hole part 111, but this nut part 70 will be described later in the "closed state". It is attached at a position corresponding to the bolt mechanism section 60.
The first horizontal pipe holding part 12 is approximately in the shape of a cylindrical part divided vertically into two and placed horizontally, and together with the second horizontal pipe holding part 22 of the second holding part 20 described later. , Finally, the horizontal pipe 3 is clamped and held in the "closed state".

The second holding part 20 includes a second vertical pipe holding part 21 and a second horizontal pipe holding part 22.
The second vertical pipe clamping part 21 roughly has a shape in which a cylindrical shape is vertically divided into two and placed vertically. In this state, the vertical pipe 2 is clamped and held.
Further, the second vertical pipe holding part 21 is formed with an elongated bolt hole part 211 for the bolt mechanism part 60. Note that a bolt mechanism section 60 is attached to the second vertical pipe holding section 21 so that the handle of the bolt passes through the bolt hole section 211. The bolt mechanism part 60 includes a bolt part 61 (consisting of a bolt handle, a bolt head, and a threaded part), a washer part 62, and a retaining part 63 (removal prevention ring, see also the bottom view of FIG. 2(b)). ) consists mainly of Note that the length dimension of the bolt portion 61 is larger than the diameter of the vertical pipe 2. The bolt mechanism section 60 is attached at a position corresponding to the nut section 70 in the "closed state".
Further, the second vertical pipe holding portion 21 has two step portions 212 along the circumferential direction of a substantially semicircumference on the inner wall surface side (it may be in the shape of three or more, or one rail shape, etc.). ), is formed by welding or the like (see also the bottom view of FIG. 2(b) and FIG. 4(a)). This stepped portion 212 comes into contact with the circumferential upper end surface of the vertical pipe 2, thereby helping the pipe joint member 1 itself to be placed on the vertical pipe 2 (details will be described later).
Further, a band hole 213 for a band portion 40 made of resin metal or the like is formed in the second vertical pipe holding portion 21 . The base end portion of the band portion 40 passes through the band hole portion 213 and is fixed to a predetermined location on the inner wall surface side of the second vertical pipe holding portion 21 by a predetermined method. Note that the band hole portion 213 is not essential, and it is sufficient that the band portion 40 is connected to the second vertical pipe holding portion 21 by some method while maintaining a predetermined strength. A first screw hole 41 for a set screw 50 is formed in the band portion 40 .
Further, a second screw hole 214 for the set screw 50 is formed in the second vertical pipe holding portion 21 . A set screw 50 (tapping screw, etc.) is inserted into the first screw hole 41 of the band portion 40, the second screw hole 214 of the second vertical pipe holding portion 21, and the third screw hole formed in the vertical pipe 2. The pipe joint member 1 itself is stably maintained in a position placed on the circumferential upper end surface of the vertical pipe 2 by being inserted through the screw holes (not shown) and connected by screws. (See also FIG. 4(b), details will be described later.) Note that as long as the same effect is achieved, the second vertical pipe holding part 21 and the vertical pipe 2 may be joined and connected by other known techniques without using the band part 40 or the fixing screw 50. good.
The second horizontal pipe clamping part 22 has a roughly cylindrical shape that is vertically divided into two and placed horizontally, and together with the above-mentioned first horizontal pipe clamping part 12, it finally "closes". Hold the horizontal pipe 3 in the ``state''.
Further, a convex portion 221 (tongue-shaped) is formed on the second horizontal pipe holding portion 22 (see also FIG. 5). The convex portion 221 allows the horizontal pipe 3 to remain in front of the operator (in the open state) even when the horizontal pipe 3 is placed on the second horizontal pipe holding portion 22 and the worker's hand is removed from the horizontal pipe 3. This prevents and prevents the product from rolling down (on the side).

The first horizontal pipe clamping part 12 of the first clamping part 10 and the second horizontal pipe clamping part 22 of the second clamping part 20 are connected via the hinge part 30, but in the "open state" When viewed from the side, it is installed not vertically but at an angle of about 10 degrees (preferably in the range of 5 degrees to 15 degrees) rearward (see also FIG. 5). With this, even if the horizontal pipe 3 is placed on the second horizontal pipe clamping part 22 of the second clamping part 20 and the worker's hand is removed from the horizontal pipe 3 in the "open state", the horizontal pipe does not move. 3 is prevented and restrained from rolling down to the front (to the worker's side).

Next, a method of using the pipe joint member 1 according to the present embodiment will be described in detail with reference to FIGS. 4 to 6 and the like.

First, when the first clamping part 10 and the second clamping part 20 of the pipe joint member 1 are in the "closed state", the bolt mechanism part 60 and the nut part 70 are uncoupled, and the hinge part 30, the first clamping part 10 is lifted upward to transition to the "open state" in relation to the second clamping part 20 (see also FIG. 3).

Then, as shown in FIG. 4, the operator is positioned so as to directly face the vertical pipe 2, and the two steps 212 of the second vertical pipe clamping part 21 of the second clamping part 20 are connected to the vertical pipe 2. It is positioned so as to be in contact with the upper end surface of the arc of the rear half of the circumference. At this time, since the threaded part of the bolt part 61 of the bolt mechanism part 60 or the handle of the bolt is tilted slightly forward rather than horizontally, the front half of the circumference of the vertical pipe 2 naturally It comes into contact with the upper end surface of the circular arc. In this state, the pipe joint member 1 itself is placed on the vertical pipe 2 for the time being. Note that the screw holes (not shown) formed in the vertical pipe 2 are adjusted so as to correspond to the second screw holes 214 of the second vertical pipe holding part 21.
Then, adjust the position of the band part 40 made of resin metal etc. so that the screw hole part 41 of the band part 40 corresponds to the screw hole part (not shown) formed in the vertical pipe 2. , the set screw 50 (tapping screw, etc.) is inserted into the first screw hole 41 of the band portion 40, the second screw hole 214 of the second vertical pipe holding portion 21, and the second screw hole formed in the vertical pipe 2. Insert into the third screw hole (not shown) and secure with the screw. Thereby, the state and posture in which the pipe joint member 1 itself is placed on the circumferential upper end surface of the vertical pipe 2 can be stably maintained.
Note that the screw holes (not shown) formed in the vertical pipe 2 may be made by using screw holes provided in the product in advance, or if necessary during the main work of the pipe joint. The screw hole portion may be simply formed at a predetermined location using a predetermined drill tool or the like, or the screw hole portion may be formed simultaneously with screw fixing using a one-touch screw or the like.

Next, as shown in FIG. 5, the worker holds the horizontal pipe 3 from the front side of the pipe joint member 1 in the "open state" and holds it in the second horizontal pipe clamping part 22 of the second clamping part 20. Place it on. In addition, in this case, the second horizontal pipe holding part 22 may be formed in a size such that the horizontal pipe 3 can be snapped into place.
At this time, the first horizontal pipe clamping part 12 of the first clamping part 10 and the second horizontal pipe clamping part 22 of the second clamping part 20 connected via the hinge part 30 are opened. Since the second horizontal pipe of the second clamping part 20 is installed so that it is not vertical but tilted backward at an angle of about 10 degrees (preferably in the range of 5 degrees to 15 degrees) when viewed from the side in the "state", the second horizontal pipe of the second holding part 20 Even if the horizontal pipe 3 is placed on the clamping part 22 and the worker's hand is removed from the horizontal pipe 3, the horizontal pipe 3 will remain in the front (towards the operator) of the second horizontal pipe clamping part of the second clamping part 20. 22 is prevented and restrained from rolling down.
In addition, since the second horizontal pipe clamping part 22 has a convex part 221 (tongue-shaped) formed at an angle that serves as a stopper, the horizontal pipe 3 can be placed on the second horizontal pipe clamping part 22. This further prevents the horizontal pipe 3 from rolling forward (towards the worker) from the second horizontal pipe clamping part 22 of the second clamping part 20 even if the worker's hand is removed from the horizontal pipe 3.・It is to be suppressed.
In this way, if the horizontal pipe 3 can be placed on the second horizontal pipe holding part 22 in the "open state" and the worker's hand can be removed from the horizontal pipe 3, the long horizontal pipe 3. Even when installing a plurality of pipe joint members 1 while adjusting their positions, etc., the convenience, efficiency, and ease of the work are improved. In particular, when the horizontal pipe is made of metal and has a certain amount of weight, it is highly useful and has the advantage that even one person can continue the work.

Finally, as shown in FIG. 6, the first clamping part 10 is lowered via the hinge part 30, and while transitioning to the "closed state" in relation to the second clamping part 20, the bolt The nut portion 70 is tightened to the threaded portion of the bolt portion 61 of the mechanism portion 60 to complete the “closed state”. When tightening this nut part 70, since the bolt hole part 211 for the bolt mechanism part 60 is formed into an elongated hole, so-called play occurs, and the bolt part 61 is changed from a substantially horizontal direction to tighten the nut part 70. Can be finely adjusted to the desired tightening angle. Note that, based on the shape of the horizontal pipe 3, etc., the direction can be adjusted by appropriately rotating the horizontal pipe 3 held between the first horizontal pipe holding part 12 and the second horizontal pipe holding part 22, as necessary. It may be something you do.
In this way, the pipe joint member 1 holds the vertical pipe 2 in the vertical direction by the first vertical pipe clamping part 11 and the second vertical pipe clamping part 21, and the first horizontal pipe clamping part 12 and the second horizontal pipe holding part 22 can hold the horizontal pipe 3 in the horizontal direction.

According to the present embodiment described above, the two vertical and horizontal pipes do not overlap and the thickness dimension is doubled, and the appearance is smart, and after the vertical pipe 2 is positioned, the vertical pipe 2 is To provide a joint member for a pipe, which allows the user to independently install a horizontal pipe 3 from the front direction (worker's side) and prevents the horizontal pipe 3 from rolling forward even if the user releases his/her hand during installation. Can be done.

[Modification 1]
As shown in Fig. 7, when the horizontal pipe 3 has a bent shape at both ends (corner pipe), the bent part tends to be downward due to gravity during the installation work of the horizontal pipe 3, but when in use, the bent part tends to be downward. If you want to position the part horizontally, you can adjust the direction by appropriately rotating the horizontal pipe 3 held between the first horizontal pipe holding part 12 and the second horizontal pipe holding part 22. good.

[Modification 2]
Two horizontal pipes 3 are connected by a known joint member (a type that is inserted into the inner wall of the pipe), and are held together as a horizontal pipe 3 by a first horizontal pipe clamping part 12 and a second horizontal pipe clamping part 22. It may also be an embodiment.

The above-described embodiments are preferred embodiments of the present invention, and various changes in shape, size, ratio, etc. can be made without departing from the gist of the present invention.
