Description

Panel Bonding Structure with Easy Processing and Strong Bonding Force

The present invention relates to a panel coupling structure that is easy to process and has a strong bonding force, and in the combination of a vertical panel and a horizontal panel applied to furniture, etc., a fastening bolt penetrates the horizontal panel and is coupled to a fastening hole inserted into the vertical panel and a fastening bolt An integrated through-hole shape including a nut hole into which a barrel nut is mounted is simply formed on a vertical panel in a single processing process, and the protrusions of the vertical panel formed on the left and right of the fastening hole are coupled to the joint groove or joint hole of the horizontal panel and then fastened. When the bolt is screwed into the barrel nut in a spiral rotation, the barrel nut is tightly tightened according to the rotation of the tightening bolt and lifted up in the direction of the tightening bolt, but the movement is restricted by being blocked by the nut ball, so the tensile force pulling the nut ball is farther apart from the protruding part. It acts as a pushing force to generate a strong clamping force between the protrusion and the joint hole or joint groove, thereby increasing the bonding force, thereby forming a combined structure with an easy processing of a single process to form an integrated through hole. At the same time, a strong bond can be achieved It is about panel bonding structure.

In general, in the production of furniture, vertical and horizontal panels are combined to form various shapes and uses, and when furniture is completed through various processes with the combination of vertical and horizontal panels as a partial element, a large load is applied afterwards. Because of this, it is important to ensure that the vertical and horizontal panels can be firmly bonded.

Therefore, when combining vertical and horizontal panels, if the panels are made of wood, there is a method of combining them by structural form, such as digging grooves directly between the panels to make them interlock, and in case of wood or iron, through the outer surface of one panel, There is a method of combining by parts such as a coupling member, such as through which the coupling member penetrates and is inserted into the side of the edge of the other panel to firmly bind the panels on both sides.

As a conventional method, when combining a vertical panel and a horizontal panel, a hollow is formed in the longitudinal direction along the width of the panel at the upper end of the central part in the longitudinal direction of the vertical panel in the longitudinal direction, and the panel is installed at a predetermined position on the upper side of the vertical panel. Through-holes are processed by penetrating from the side, processing such that the hollows and through-holes are orthogonal, forming holes opposite to the hollows in the horizontal panels, placing the horizontal and vertical panels so that the holes and the hollows face each other, and then bolting through the holes. is inserted and screwed together through a barrel nut inserted into the through hole. As in the above procedure, the hollow is processed along the narrow cross section of the vertical panel, and the through hole is precisely processed to penetrate and connect the hollow from the side. Therefore, the procedure is complicated and difficult, and the probability of failure is high.

In addition, even if a protrusion is formed on a vertical panel and a groove is formed on a horizontal panel, they are fitted to each other, and then they are mutually fastened using bolts and nuts, the protrusion and groove only help to maintain the shape between the mutually perpendicular panels, and practically both panels Since the bonding strength between the panels is determined only by bolts and nuts, the bonding strength is relatively low, and as time passes and the applied load increases, the bonding strength between the vertical panel and the horizontal panel gradually decreases.

However, the previous inventions are trying to increase the bonding force between panels only through the method of using a larger number of larger and stronger bonding members. There is a problem.

A panel coupling structure 10 that is easy to process and has strong bonding strength according to a preferred embodiment of the present invention includes a vertical panel 100, a horizontal panel 200, a fastening bolt 300 and a barrel nut 400, and a vertical panel 100 includes a fastening hole 110 and a protrusion 120, and the horizontal panel 200 includes a coupling portion 210.

The vertical panel 100 and the horizontal panel 200 are vertically coupled to each other in the manufacture of furniture, etc., and are parts that form the shape of furniture. In one embodiment of the present invention, the horizontal panel 200 is a vertical panel ( 100) may have a structure that is vertically opposed to each other, fitted and coupled by the vertical panel 100, and mutually fastened and assembled between the respective panels.

The front end of the vertical panel 100 and the front end of the horizontal panel 200 are mutually coupled, and the vertical panel 100 has a narrow surface as a coupling part and is fitted to the wide surface of the horizontal panel 200. can

The fastening hole 110 is a through hole formed with a predetermined length in the inner longitudinal direction of the vertical panel 100 from the front end of the vertical panel 100, and one surface of the front end of the vertical panel 100 of the fastening hole 110 is open to secure the fastening bolt It forms an inlet portion 111 into which 300 is inserted, and has a closed shape on three sides in the inner longitudinal direction of the vertical panel 100, and has a structure penetrated in the front and rear directions when viewed from the front, and a straight groove with one side pierced. can be a shape.

The fastening hole 110 serves as a passage for accommodating the fastening bolt 300 so that the fastening bolt 300 is inserted from the outside of the horizontal panel 200, penetrates the horizontal panel 200, and enters the vertical panel 100. Therefore, the fastening hole 110 is a straight line opposite to the screw portion of the fastening bolt 300, and its width is capable of accommodating the fastening bolt 300 so that the fastening bolt 300 can be spirally rotated and inserted. It should be wide.

However, as the width of the fastening hole 110 widens, the upper end of the fastening hole 110 and the front end protrusion 120 of the vertical panel 100 become narrower, so the cross-sectional area coupled with the horizontal panel 200 becomes smaller and the bonding force is weakened. Also, since the barrel nut 400 must be fitted and fitted to the fastening hole 110, the width of the fastening hole 110 must be smaller than the diameter of the barrel nut 400.

Therefore, the width of the fastening hole 110 is almost similar to the diameter of the screw of the fastening bolt 300 to the extent that the fastening bolt 300 can rotate while being accommodated in the fastening hole 110, so it is formed in a form that is almost in close contact. Preferably, the length of the fastening hole 110 is preferably formed to be longer than the screw tip of the fastening bolt 300 by a predetermined length.

A cylindrical nut hole 112 into which the barrel nut 400 can be inserted and mounted may be formed at the center of the fastening hole 110 in the longitudinal direction.

When the barrel nut 400 matches the spirally formed through hole on the inner circumferential surface with the longitudinal direction of the fastening hole 110 and is inserted into the nut hole 112, the fastening bolt 300 penetrates the horizontal panel 200 and is inserted into the barrel nut The horizontal panel 200 and the vertical panel 100 are tightly coupled and tightened while being screwed into the through hole of the 400.

In this way, in the mutual coupling of the vertical panel 100 and the horizontal panel 200, fastening by coupling members such as bolts and nuts is performed by the above-described fastening hole 110 and nut hole 112, and fastening bolt 300 and barrel It can be performed by the nut 400. On the other hand, the vertical panel 100 and the horizontal panel 200 are mutually fitted and fitted parts of the vertical panel 100 protrusion 120 and the horizontal panel 200. The shape of the coupling part 210 can also be achieved at the same time.

The protrusion 120 is a portion protruding from the front end of the vertical panel 100 and is fitted into the joint groove 211 or joint hole 212 of the horizontal panel 200 and has a step 121 at the front end of the vertical panel 100. As this is formed, the protrusion 120 may be formed.

That is, the protruding portion 120 is provided at the front end of the vertical panel 100 and may be provided at least one or more positions of the left and right sides around the inlet portion 111 of the fastening hole 110, and in order to form a protruding shape, the vertical panel The step 121 is formed at the front end of the step 100, and the protrusion 120 may be configured as a protruding part on the side of the step 121. For example, as shown in FIG. 2A , the protrusion 120 may be exemplified as a left protrusion 120a formed on the left side of the inlet portion 111 and a right protrusion 120b formed on the right side.

The front end of the horizontal panel 200 may be provided with a coupling portion 210 opposite to the protrusion 120 formed at the front end of the vertical panel 100 .

Coupling part 210 is formed on the lower surface of the front end of the horizontal panel 200 in the form of a through hole in the form of a groove so that the protrusion 120 can be fitted in a tight fit form, or the horizontal panel 200 in the form of a through hole It can be configured by penetrating the tip of.

The coupling part 210 in any form of the groove or through hole may include a bolt hole 213 so that the fastening bolt 300 coupled to the fastening hole 110 can be inserted through.

When the protrusion 120 is fitted into the coupling portion 210 and the vertical panel 100 and the horizontal panel 200 form a vertically coupled form, the stepped portion 121 provided on the side of the protrusion 120 is the coupling portion. Around (210), that is, a structure is formed in contact with and supported by the lower surface of the horizontal panel (200).

Therefore, when the protrusion 120 is inserted into the coupling portion 210, the protrusion 120 enters the coupling portion 210, and the step 121 is caught on the lower surface of the horizontal panel 200 around the coupling portion 210, and further insertion is performed. stopped and fitting is completed.

The protrusion 120 and the coupling portion 210 should be mutually compatible so that they are not loose after coupling, preventing the vertical panel 100 and the horizontal panel 200 from shaking. It is preferable that the length of the horizontal panel 200 coincides with the thickness of the coupling portion 210 or the depth of the coupling portion 210 when the coupling portion 210 is in the form of a groove.

As described above, the shape of the fastening hole 110 is a straight through hole with one side open and a circular nut hole 112 convex at a predetermined location in the center, while the shape is constant in various embodiments of the present invention. , The shape and position of the protruding portion 120 and the step 121, and the configuration and shape of the coupling portion 210 may be configured in various shapes according to various embodiments of the present invention.

Therefore, in describing various embodiments of the present invention, as described below based on classification according to the position of the protrusion 120 and the step 121 and the shape of the coupling part 210, from one embodiment to the second additional embodiment It is divided into 4 types to explain.

go. one embodiment

First, according to an embodiment of the present invention, the fastening hole 110 of the panel coupling structure 10, which is easy to process and has a strong bonding force, may be formed at the center of the front end of the vertical panel 100.

In addition, the protruding portion 120 is in contact with the inlet portion 111 of the fastening hole 110 and is formed to protrude from the left and right, respectively, and the stepped portion 121 is formed on the outside of the protruding portion 120, that is, on the outside of the front end of the vertical panel 100, respectively. can

That is, the protrusion 120 is formed while the inner surface of the through hole forming the fastening hole 110 extends as it is to the front end of the vertical panel 100, and the step 121 is formed on the outside of the protrusion 120, that is, the vertical panel 100 ) It may be formed while the stage is lowered in the outer direction of the.

Coupling part 210 is configured on the front lower surface of the horizontal panel 200 so as to be opposed to the protruding part 120 and may be configured to include a joint groove 211 and a bolt hole 213, the joint groove 211 is a plurality It may be provided in a rectangular grooved form according to the shape of the outline formed by the protrusion 120 and the fastening hole 110 of the inlet 111, and the bolt hole 213 is the center of the joint groove 211. It may be formed in the through hole into which the fastening bolt 300 can be inserted.

Coupling part 210 is in the form of a rectangular groove formed long to the left and right when viewed from the lower surface of the horizontal panel 200, and a bolt hole 213 is drilled in the center of the groove, and viewed from the upper surface of the horizontal panel 200. At the time, only the bolt hole 213 may be visible.

A total of three surfaces of the plurality of protrusions 120, such as an outer surface and two surfaces consecutive to the outer surface, are fitted and fitted to both sides of the joint groove 211, and the inner surface of each protrusion 120 is a bolt hole 213 And it is composed of a shape facing each other with the fastening hole 110 therebetween, so that the vertical panel 100 and the horizontal panel 200 can be fitted.

When the fastening bolt 300 is inserted through the bolt hole 213 from the upper surface of the horizontal panel 200 in the fitted state of both panels, and is drawn into the fastening hole 110 and inserted into the barrel nut 400, a spiral rotational coupling occurs. It can be done.

When it comes into contact with the upper surface and in this situation, if the spiral rotation is further performed by a predetermined distance for complete tightening within the possible range, the fastening bolt 300 has no place to go down anymore, so the barrel nut 400 is pulled up by the fastening bolt 300 Force, that is, tensile force is applied to the barrel nut 400. Since the barrel nut 400 is also fitted and coupled to the nut hole 112, it cannot be pulled up, so the tensile force is applied in the direction of widening the fastening hole 110 It acts as a push to the left protrusion (120a) and the right protrusion (120b) in a mutually spaced direction.

Since the protrusions 120 are tightly fitted into the joint grooves 211, when force is applied so that the protrusions 120 are mutually pushed in the direction in which they are spaced apart, the protrusions 120 are more tightly fastened to the joint grooves 211 and tightly tightened. Since the clamped step 121 strongly supports the lower surface of the horizontal panel 200, the force of the protrusion 120 being tightened to the joint groove 211 is supported to form a stronger bonding force.

Therefore, the vertical panel 100 and the horizontal panel 200 form a very strong coupling state by adding the coupling force of the protrusion 120 and the joint groove 211 to the coupling force by the fastening bolt 300 and the barrel nut 400.

In one embodiment of the present invention described above, the vertical panel 100 and horizontal The fact that the panel 200 forms a strong bond is a feature that is commonly applied to other and additional embodiments of the present invention, and this method forms a stronger bond with a simple process of forming a single fastening hole 110.
