Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connection member using a magnet,

The present invention relates to a connecting member in which a mini-fix is fixed by using a magnetic force, and a partition which is variously assembled using the connecting member.

In the partition installation, it is necessary to connect a plurality of panels, and frame connection elements are used for adjusting the height of the panel, extension and the like.

The connection of the partitions consists of a connection between neighboring panel flames. The frame is used by injecting plastic or molding it with metal. In the case of plastic, it is usually made by drawing injection molding, so that a method of putting a band in the groove of neighboring frames is used.

In a metal partition, on the other hand, each frame of a neighboring panel is usually fastened using bolts and nuts. Conventional bolt and nut fastening methods have the advantages of convenience of purchase and robustness after installation, but they require a lot of time and effort in installation work, and it is troublesome to use power tools. Particularly, when relocating, repairing and replacing partitions, it is very troublesome to unfasten many bolts and nuts connecting the partitions and then tighten them again.

In addition, in the case of connecting the panel vertically, the auxiliary frame in the form of a square bar is usually used. In the conventional bolt and nut connection method, the bolt and the nut are easily interfered with each other in the auxiliary frame having a narrow cross- There is also a disadvantage that it is quite inconvenient to enter a bell tool.

Korean Patent Publication No. 20-1994-0007018 (Apr. 14, 1994) Korean Patent Publication No. 10-2009-0099031 (2009.098.21) Korean Patent Publication No. 10-2015-0086788 (2015.07.29)

The present invention proposes a connection member capable of variously arranging a partition installation scheme, securing convenience of attachment and detachment of various attachments, enabling installation and disassembly of a quick and easy partition, and a partition using the connection member.

Other objects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description.

According to an aspect of the present invention, there is provided a mini-fix comprising: a mounting hole in which a tip of a mini-fix is inserted and a mounting hole in which a mini-fix having a band-shaped recess is formed around an outer circumferential surface of a tip, A body portion having a side hole in which a part of the mounting hole overlaps with the mounting hole, and a body portion mounted in the side hole, wherein the mini-fix is inserted into the mounting hole, And a pair of actuators for moving the mini-fixes close to each other to fix the mini-fix.

Here, the mounting hole communicates with the side hole, and a separating hole for partially exposing the operating member may be formed. This separating groove allows the minifix to be separated through a separating tool.

Further, the pair of actuators may have a spherical or cylindrical shape, and at least one of them may be a permanent magnet. The pair of actuators has a property of sticking to the permanent by the magnetic force, and acts to fix and fix the recess of the mini-fix.

On the other hand, at a position where the mounting hole overlaps with the side hole, a stopper projection protruding from the inner circumferential surface of the side hole may be protruded to limit movement of the actuator. The stopper protrusion prevents the stopper protrusion that has entered the side hole from being biased toward one side or away from the side hole when the mini-fix is not mounted.

For example, the body may include a first branch and a second branch that are inserted into two profiles that meet vertically, wherein either the first branch or the second branch is provided with the actuating body, A nut for screw tightening may be mounted on the second branch. The configuration of the body part can be variously changed.

Also, the present invention proposes a partition including a connecting member using the above-described magnet, as a frame connecting part forming an outer frame, a panel plate mounted on the frames, and a corner connecting part of frames.

According to the embodiment of the present invention, the mini-fix can be coupled in a fitting manner, so that the partition can be installed quickly and easily. In addition, the mini fix can be unlocked by the separating tool alone, and the partitioning operation of the partition can be easily performed. It is easy to expand the partition, and the structural reliability improves operational reliability and reduces the possibility of failure.

The effects of the present invention will be clearly understood and understood by those skilled in the art, either through the specific details described below, or during the course of practicing the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. It should be noted, however, that the drawing numbers for the same or similar components throughout the drawings and embodiments shall be used collectively.

In the following description, terms such as 'first', 'second', and the like are used to distinguish constituent elements whose technical meaning is within the same range for convenience. That is, any one configuration may be arbitrarily referred to as a 'first configuration' or a 'second configuration'.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, therefore, are not to be construed as limiting the technical spirit of the invention. It is to be understood that the invention is not to be limited by any of the details of the description to those skilled in the art from the standpoint of a person skilled in the art that any or all of the drawings shown in the drawings are not necessarily the shape,

A connecting member using a magnet according to an embodiment of the present invention (hereinafter, referred to as a 'connecting member') can fix the mini-fix shown in FIG.

The mini-fix 10 has a substantially rod shape, and the tip 101 protrudes convexly and is conical. A depressed groove 102 is formed around the outer peripheral surface of the tip portion to form a strip-shaped concave groove. In the mini-fix 10a shown in Fig. 6, a thread 103 is formed on the outer peripheral surface of the mini-fix 10a, It is in the form of a rod. In addition to the illustrated embodiment, the shape of the rear end of the mini-fix may be varied in various ways.

The connecting member 1 shown in Figs. 1 and 5 has a body portion 11 which forms an outer shape and the body portion 11 includes a first branch 11a and a second branch 11b . The first branch 11a and the second branch 11b are in a perpendicular relationship to each other and each branch 11a and 11b is used to vertically connect the two profiles by inserting into the profile (frame of the partition).

For example, the partition 300 shown in FIG. 6 is formed by assembling four rectangular panels P1, P2, P3, and P4. The edge of each of the panels P1, P2, P3, The frames are assembled and assembled. At this time, the connection member 1 shown in the connection of the frames which meet vertically is used. That is, the connecting member 1 is used for each corner of the panels P1, P2, P3, and P4.

The panels P1, P2, P3, and P4 are completed by forming rectangular frames with frames and connecting members, and then joining the panel plate members to the front and rear surfaces. This panel is installed alone or in plurality to become the partition 300.

Referring again to FIGS. 1 and 5, a nut N for screw tightening is mounted inside the second branch 11b of the connecting member 1. As shown in FIG.

For this purpose, a groove into which the nut (N) is inserted is formed in the second branch (11b). A through hole 114 is formed in the second branch so that a screw hole of the nut N is exposed. As a result, various attachments can be detachably mounted on the nuts provided on the second branch.

The nut N may be provided on the first branch or the second branch according to the embodiment and in the embodiment shown in Figure 7 the nut N may be provided on both the first branch 11a and the second branch 11b Respectively.

The shape and shape of the connecting member can be variously changed. For example, in the case of forming a three-dimensional structure, the connecting member may be provided with three branches which are perpendicular to each other.

At least one of the branches provided on the connecting member is provided with an operating body (2) to be described later. In the illustrated embodiment, the actuating body is provided only in the branches in the vertically laid direction.

In yet another embodiment, the actuators may be installed in both the first branch and the second branch. Also, the nuts can be installed in both the first branch and the second branch, and when the positions are overlapped, the actuators and the nuts can be arranged side by side along the longitudinal direction of the branches (see FIG. 7).

A mounting hole 111, a side hole 112, and a separation hole 113 are formed in the body portion 11 constituting the first branch. In another embodiment not shown, the separation hole 113 may be omitted.

The mounting hole 111 is formed to be long in accordance with the direction in which the mini-fix 10 is coupled. In the illustrated embodiment, the mounting hole 111 is parallel to the direction in which the screw hole of the nut is provided. The periphery 11a of the mounting hole 111 is depressed toward the center of the mounting hole 111 so that the mini-fix 10 coming into the mounting hole 111 is directed toward the center of the mounting hole 111.

The longitudinal direction of the side hole 112 lies in a direction transverse to the mounting hole 111. The side holes 112 are formed somewhat higher than the center line of the mounting holes 111, so that the side holes 112 partially overlap with the mounting holes 111. Referring to FIGS. 2 and 5, it can be seen that the lower end of the circular cross section of the side hole 112 is located close to the center height of the cross section of the mounting hole 111. Both holes are communicated through a portion where the mounting hole 111 and the side hole 112 overlap each other.

Referring to FIGS. 2 and 3, a stopper projection 112a protrudes from the inner peripheral surface of the side hole 112 at a position where the mounting hole 111 and the side hole 112 overlap each other. The stopper protrusion 112a restricts the movement of the actuating member 2 contained in the side hole 112. [

The separation hole 113, which is an optional element, is a hole communicating with a portion where the mounting hole 111 and the side hole 112 overlap, and is formed in the vertical direction in FIGS. 1 to 2 and 5. The diameter of the circular cross section of the separation hole 113 is somewhat smaller than that of the side hole 112. [ A part of the operating body 2 is exposed through the separation hole 113 and the separating tool 20 described later can be inserted to forcibly open the gap of the operating body 2. [

Referring to FIG. 2, a pair of actuators 2 is inserted into the side hole 112. The actuating body 2 may be a pair of permanent magnets. Or one actuator may be a permanent magnet, and the other one may be a magnetic substance or a ferromagnetic substance adhering to the permanent magnet.

In the illustrated embodiment, the actuating body 2 is spherical. As another embodiment, the cylindrical actuator 2a can be used instead of the spherical actuator. In the case of the cylindrical actuating member 2a, the peripheral edge 21 at both ends is processed into a curved surface.

The operating body 2 is subjected to the sectional shape of the side hole 112, and its shape can be changed. For example, when the side holes are rectangular, the actuating body can be formed into a hexahedron having a square cross section.

Although not shown, the actuating member can be replaced with a case slidable in the side hole and a permanent magnet mounted inside the case. In this case, the case may be made of various shapes of metal, and the permanent magnet may be advantageously used in various shapes that are easy to purchase. For example, as shown in Fig. 2, the case may be a cylindrical shape whose periphery is rounded to a curved surface, and a cylindrical permanent magnet without corners is provided in the case. The case made of the case and the permanent magnet can be selected as a material which is resistant to abrasion due to contact with the mini-fix or the separating tool, so that the life of the connecting member can be easily increased.

Since the actuators 2 have the property of being attached to each other by the magnetic force, they are held in the front and rear with the stopper protrusion 112a as the center, as shown in Fig. 3 (b). Even if the connecting member 1 is tilted in this state, any one of the actuating members 2 is caught by the stopper protrusion 112a, so that the actuating member 2 does not separate from the side hole 112. [ This makes it possible to tilt the connecting member arbitrarily, thereby facilitating handling of the connecting member in which the operating bodies are embedded.

Also, the stopper projection 112a allows the two actuators 2, which are attracted by the magnetic force, to stay in a proper position in the circular cross section of the mounting hole 111. [ That is, the inclined surface of the leading end of the incoming mini-fix 10 can make complete contact with the curved surface of each actuating body 2, thereby ensuring correct operation of the actuating body.

The operation of the actuating body 2 will be described with reference to Fig. Fig. 5 is a sectional view corresponding to the center height of the spherical operating body 2. Fig.

5 (a) to 5 (c) sequentially show the entry process of the mini-fix 10. The mounting hole 111 is formed at a lower position than the side hole 112, so that a part of the mounting hole 111 and a part of the mini-fix 10 are seen in cross-section.

5A and 5B, the inclined surface of the conical tip 101 of the mini-fix 10 comes into contact with the curved surface of the actuating body 2. [ The force for pushing the mini-fix 10 into the mounting hole 111 causes the two actuators 2 to extend in the direction away from each other on the inclined surface of the conical tip 101. [ The actuating body 2 can further enter into the mounting hole 111 on the gap thus opened.

As the mini-fix 10 is further inserted into the mounting hole 111, the actuators 2 are moved close to each other by the magnetic force by reaching the position of the recess 102 of the mini-fix. At the position of the recessed groove 102, the actuators 2 are moved close to each other by the magnetic force, and the inner wall of the recessed groove 102 is blocked by the proximity of the actuating body 2 to prevent the mini-fix 10 from being separated. Thus, the mini-fix 10 inserted into the body portion 11 is fixed.

Figure 1 shows a separating tool 20 for separating the installed mini-fix 10. The separating tool 20 is inserted into the separating hole 113 to open the separating hole 113 to expose the partially exposed portion of the working body 2. The lower end surface of the separating tool 20 is formed with a "V" When the separating tool 20 is inserted and pressed into the separating hole 113, the actuating bodies 2 are pushed in a direction away from each other on the inclination 201 at the lower end of the separating tool 20. The mini-fix 10 is pulled out with the gap of the actuators 2 being greater than the tip of the mini-fix 10 to release the fixing of the mini-fix 10 by the actuators 2, 111 can be detached from the mini-fix 10.

On the other hand, FIG. 6 shows a partition 300 using the connecting member 1 according to FIGS. 1 to 5. The connecting member 1 of the above-described embodiment is used at the corners of the panels P1, P2, P3, and P4.

The mini-fix 10 having recessed grooves 102 formed at both ends thereof is used to connect the two panels P1 and P2 which are arranged in parallel on the right side of the drawing. The end of the mini-fix 10 is inserted into the mounting hole of the neighboring connecting member 1 and is held and fixed by the actuators provided in the respective mounting holes. The mini-fix 10 is used above and below the panels P1 and P2 as the connecting member 1 is provided on one side and under the panels P1 and P2. The coupling method using the bi-directional mini-fix has a merit that it is very easy and quick to install by connecting the panels with a simple fitting method.

An auxiliary frame 302 used as a column and a grid connecting member 303 are used to connect the two panels P2 and P3 which are coupled at right angles. The grid connecting member 303 has a recess 102 formed at one end thereof and a mini-fix 10a having a thread 103 formed at the other end thereof. The connection of the grid connecting member 303 and the mini-fix 10a is made by screwing and the two panels P2 and P3 that meet vertically are coupled through the depressed grooves 102.

Although not shown, the panels may be cross-connected using a slope of the grid connecting member, or may be connected in a "T" shape.

6, an additional panel P4 may be further connected to the upper portion of the panel P3 using a mini-fix 10a having a screw thread formed on one side thereof.

The connecting member 1 of the additional panel P4 provided on the upper part is assembled so that the branch having the operating body is positioned on the bottom surface of the panel and the screw P10 is connected to the lower panel P3, The additional panel P3 on the upper side can be connected by fitting using the recess 102 of the mini-fix 10a.

6, a height adjustment unit 304 is shown. A screw rod is provided at an upper end of the height adjusting unit 304 and is screwed to a nut provided on the connecting member. By appropriately rotating the height adjustment unit 304, horizontal connection of the panels is possible even when the floor is not horizontal.

Through such panel connection, it is possible to easily and quickly construct the intended partition with various structures. Also, when disassembling partitions, one can use a separation tool to quickly unlock the mini-fix and separate the panel.

The connecting member in which the mini-fix is fixed by using the magnet can be used for joining various furniture and equipment in addition to the partition.
