The present invention relates to a joint clip for assembling a profile, which assembles profiles having an assembly groove formed by opening an outer surface in the longitudinal direction on the outer surface in the longitudinal direction and an assembling hole formed in the longitudinal direction through the central column, in more detail. A body part having a fitting hole into which a bolt fastened to the first assembly hole of the first profile is fitted, and slidingly coupled to the second assembly groove of the second profile; A bending piece that is bent inward in one direction from both left and right side ends of the body part and fitted into the first assembly groove of the first profile; And a non-slip protrusion protruding from one side surface of the body portion and contacting the locking portions on both sides of the second assembly groove, including a clip for assembling a profile for preventing assembly from being displaced.

Profiles that form the frame (skeleton) of various structures, such as shelves, cabinets, tables, and clean rooms, are usually extruded from an aluminum material, making them lightweight, high-strength, and capable of manufacturing in various forms. Easy to change and inexpensive, it is used for various purposes.

Such a profile is used by assembling a vertical profile (hereinafter referred to as a first profile) and a horizontal profile (hereinafter referred to as a second profile) of the same structure to form a right angle in a lattice shape to fit the construction design.

Briefly explaining the structure of the profile, an assembly groove formed along the longitudinal direction is formed on at least one side (generally, in the case of a rectangular profile, one or more fastening grooves are formed on four surfaces), and the longitudinal direction of the central pillar As the assembly hole is provided, the first and second profiles are connected at right angles to assemble the structure.

At this time, what is used to assemble the profiles at right angles is called a joint clip, and there are registered patent Nos. 10-1457646 and 10-1058840 for joint clips.

As a first embodiment shown in [A] of FIGS. 2, 4, and 5, the non-slip protruding portion 13 is a first protrusion 13a that is partially cut by bending a portion of the body portion 10 (13a').

There are no restrictions on the position or number of the first protrusions 13a and 13a', but it is preferable that at least two first protrusions 13a and 13a' are provided on each side of the fitting hole 11, respectively.

At this time, the first protrusions 13a and 13a' may be formed by cutting a portion of the front and rear side ends of the body portion 10 and bending the cut portion in one direction, as illustrated in FIG. 2,

Alternatively, as shown in [A] of FIG. 5, a portion of the middle portion of the body portion 10 may be cut to form the incised portion by bending in one direction.

Also, the shape of the first protrusions 13a and 13a' is not limited.

In FIG. 2, the first protrusions 13a provided at both front and rear ends of the body portion 10 are cut in a square shape to bend and form an embodiment, and in FIG. 5A, the body portion 10 is An example in which a first protrusion 13a' provided in the middle portion is cut and then bent can be confirmed.

Of course, in the case of the first protrusion 13a of FIG. 2, a triangular shape with a sharp end is also possible.

Next, as a second embodiment shown in [B] of FIG. 5, the anti-skid protrusion 13 is composed of a second protrusion 13b protruding unevenly from one side of the body 10.

The second protrusion 13b is preferably made of a triangular concave-convex shape, and may be provided on both front and rear sides of the fitting hole 11 as shown in the drawing, or the second protrusion 13b is front and rear of the body portion 10. It may be provided in a form that crosses the whole.

At this time, there is no restriction on the number and shape of irregularities of the second protrusion 13b.

Since the body portion 10 is spaced apart from the pillar portion 3 of the first profile P1 by the bending piece 12, the first and second protrusions 13a in the temporary engagement state of the joint clip JC (13a') 13b) the end portion of the second assembly groove (1b) does not contact the engaging portion (2b) of the joint clip (JC) can be coupled to the second assembly groove (1b) sliding, and then the first When the first bolt 20 is tightened by inserting a wrench through the through hole 5, the body portion 10 is in close contact with the engaging portion 2, and the first and second protrusions 13a, 13a', 13b As the end part digs in contact with the engaging portion 2b, the joint clip JC has an effect of being fitted into the engaging portion 2b of the second assembly groove 1b, so that the profiles P1 and P2 do not slide And a solid assembly is maintained.

Subsequently, as a third embodiment shown in [C] of FIG. 5, the second profile P2 has a fitting groove 2ba in which a part of both side locking portions 2b of the second assembly groove 1b is cut in a circle. Including,

The non-slip protruding portion 13 is formed of a third projection 13c that protrudes from the rim of the fitting hole 11 and fits into the fitting groove 2ba.

The third projection (13c) is a circle corresponding to the fitting hole 11, the projecting height is projected to have a height smaller than the thickness of the engaging portion (2) of the second profile (P2).

The third projection (13c) is the joint clip (JC) in the state coupled to the first profile (P1), the body portion (10) is spaced apart from the pillar portion (3) of the first profile (P1) third Since the protrusion 13c does not contact the locking portion 2b of the second assembly groove 1b, sliding engagement is possible with the second assembly groove 1b, and then a wrench is inserted into the first through hole 5 to remove the protrusion. When the 1 bolt 20 is tightened, the body part 10 is in close contact with the locking portion 2b of the second assembly groove 1b of the second profile P2, and the third protrusion 13c is the fitting groove 2ba. It is fitted and fixed by the engagement (contact) of the third protrusion 13c and the locking portions 2b on both sides, so that the profiles P1 and P2 do not slip and a robust assembly is maintained.

At this time, the third projection (13c) is preferably made of a circular arc shape separated from each other, not a complete circle.

On the other hand, in order to prevent the sliding of the profiles (P1) (P2), the present invention is a fixed piece (14) formed to be extended to the outside while being bent in the opposite direction of the anti-skid protrusion (13) at one side end of the body (10) Including, the fixing piece 14 is provided with a screw tab 14a to which a second bolt (not shown) is screwed through both sides of the fixing piece 14.

That is, the body portion 10 is formed to be longer than the normal length, and the left and right one side middle portions are incised to bend the incised portion inward in one direction to form the bent piece 12, and then the remaining portions are bent portion 14b. Bending in the other direction from the starting point to mold the fixed piece (14).

The fixing piece 14 is formed to protrude longer than the outer surface of the first profile P1, and the screw tab 14a is provided at a position spaced apart from the first profile P1.

At this time, the second profile (P2) in the form corresponding to the first through-hole (5), the perforated in the direction perpendicular to the longitudinal direction of the pillar portion (3) at a position corresponding to the screw tab (14a) 2 It has a through hole (not shown).

Therefore, when the temporarily coupled joint clip (JC) is slidingly coupled to the second assembly groove (1b), the screw tab (14a) is exposed by the second assembly groove (1b), and using this, the second bolt is applied to the screw tap ( When tightened in combination with 14a), the threaded portion of the second bolt penetrates through the screw tab 14a and fits into the second through hole to prevent slippage of the joint clip JC, that is, the first profile P1, so that it is fixed more firmly. Combined.

The fixing piece 14 using the second bolt is fixed by the interference fitting method of the joint clip JC and the second assembly groove 1b together with the anti-slip protrusion 13 by the first bolt 20. By keeping it stronger, it is possible to keep the assembly of the profiles P1 and P2 more robust.

At this time, the bent portion 14b is formed to be rounded like the guide protrusion 15 to be described later, and a jam occurs when the joint clip JC temporarily coupled to the first profile P1 is inserted into the second assembly groove 1b. Do not.

Furthermore, the body portion 10 is raised in the opposite direction of the anti-skid protrusion 13 to the front and rear ends of the bending piece 12, more specifically, the bending piece disposed in a direction in which the fixed piece 14 is not connected. It includes a guide projection (15) connected to bend at an angle.

This is in the conventional joint clip (TJC), the end portion of the body portion 10 formed on both front and rear sides of the bent piece 12 is'-' shaped to fit the end portion of the joint clip into the second assembly groove (1b) This is due to the fact that it is not easy to fit the joint clip JC because it is caught on the inner surface of the locking portion 2b.

Accordingly, the end portion of the body portion 10 or the fixed piece 14 through the guide protrusion 15 is not caught in the engaging portion 2b of the second assembly groove 1b, so that the sliding coupling of the joint clip JC, That is, the operation of moving the first profile P1 in the longitudinal direction of the second profile P2 can be performed more easily.

Of course, when the joint clip JC is fitted in the direction in which the fixing piece 14 is provided, not in the direction in which the guide protrusion 15 is provided, the bent portion 14a replaces the function of the guide protrusion 15.

On the other hand, the present invention is characterized in that the first bolt 20 is not separated from the fitting hole 11 but is made of an integral type coupled to be idle.

In order to prevent the first bolt 20 from being detached from the fitting hole 11, after inserting the screw portion of the first bolt 20 into the fitting hole 11, both front and rear sides of the body portion 10 are inward. A method of deforming the circular fitting hole 11 into an oval shape by pressing, alternatively, a method of removing the thread under the head of the first bolt 20 to be caught in the fitting hole 11 may be considered.

Through this, it is possible to prevent the loss of the first bolt 20 when assembling the profile, and such an integrated first bolt 20 can be equally applied to the coupling structure of the second bolt and the screw tab 14a.

Furthermore, the bending piece 12 is provided with identification grooves 12a on one side or both sides of the vertical bending portion.

The identification groove (12a) is a first bolt (20) when the joint clip (JC) is temporarily coupled, by tightening the first bolt (20) only to the height of the identification groove (12a), the joint clip (JC) second When fitting into the assembly groove 1b, it is possible to maintain an optimal height at which mutual friction does not occur.

In the above description, the joint clip for assembling the profile has been mainly described with reference to the accompanying drawings, but the present invention is capable of various modifications, changes and substitutions by those skilled in the art, and such modifications, changes and substitutions are protections of the present invention. It should be construed as being within the scope.
