The present invention relates to a rotating coupling member provided with a magnet, and more specifically, to each of the opposite inner surface edge portions of the disk-shaped fixed plate and the rotating plate facing each other, the direction is wrong but interlocking with the "b", "b" The fixed rail and the rotating rail of the cross section protrude along the arc, and the magnet and the magnetic body are fixedly coupled to the center of each opposing inner surface, so that the rotating rail of the rotating plate is slid along the fixed rail of the fixed plate whose outer surface is fixed to the object. It is rotated, and even when the rotating rail is out of the fixed rail, and the coupling state of the fixed plate and the rotating plate by the attraction between the magnet (magnetic force) and the magnetic plate to maintain the detachable.

Coupling members used to join two objects have a wide variety of structures and shapes. For example, a coupling member such as a hinge or a magic tape is generally composed of a pair of small members. The member is either a structure that can be repeatedly combined in a separated state (magic tape) or a structure that is fixedly coupled in a rotatable state with respect to each other (hinge), such a coupling member can be used in various ways depending on the object. Here are some typical uses:

An example of a coupling member used for repeatedly simple coupling of two coupling targets is that of a monitor external speaker disclosed in Korean Utility Model Publication No. 1999-13898 (hereinafter referred to as "quoting design 1"). As illustrated in FIG. 1, a fastening structure is provided. Each of the rotating half fastening grooves 11A formed integrally on both sides of the television main body 11 and a pair of detachable speakers 12 are provided respectively. The rotary disk 12A serves as a coupling member.

At this time, in the rotary half fastening groove (11A) the engaging head (11B) is formed to protrude in two places opposite to each other, the rotating plate (12A) is provided with a fixing clip (12B) corresponding to the locking head (11B) The locking head 12B is inserted into and coupled to each fixed clip 12B in a rotationally sliding manner. Such a coupling structure allows the rotating disk 12A to be rotated with respect to the rotating disk fastening groove 11A. It merely serves to detach the main body 11 and the speaker 12 to be detachably separated, and does not have any function for other objects other than the object to be combined.

Unlike the coupling member of Proposition 1, which consists of a turntable engaging groove and a turntable, the domestic registration room No. 380546 (referred to as "quoting quotation 2") discloses a door pinching prevention bar, as shown in FIG. As described above, this is a case in which the coupling member acts on another object, and the fixed part 21, which is a small member, is fixedly coupled to the door, and the rotating part 22, which is another small member, is coupled to the fixed part 21, The cam-shaped elastic member 23 is detachably fixed to the rotating part 22.

Coupling member of the citation 2 is used to prevent the hand caught between the door and the door frame and look at the usage thereof as follows.

When the rotating part 22 is rotated together with the elastic member 23 with respect to the fixing part 21 fixed to the door, the convex part of the elastic member 23 protrudes to the outside of one end surface of the door, and in this state When the door is closed, the elastic member 23 protruding from the one end surface of the door is sandwiched between the door and the door frame to form a gap between the door and the door frame, to prevent the hand and the like from being hurt between the door and the door frame. It becomes possible.

That is, the coupling member of the citation proposal 2, unlike the citation proposal 1, in which the action is limited only to two coupling objects, the door frame which is not the coupling object is fixed to the door and the elastic member 23 so as to be rotatably fixed, and belongs to the range of operation. do.

However, the coupling member of Proposition 2 has a complicated structure in which a spring s is interposed between the fixing part 21 and the rotating part 22, and the fixing part 21 and the rotating part 22 can be separated. However, when there is no separate tool such as a driver, the separation of the two members-the fixing part and the rotating part-is not only easy, the structure is complicated, there is a problem that the manufacturing cost increases.

The present invention has been devised to solve all the problems of the conventional coupling member composed of a pair of small members that can be separated from each other, so that the other small member with respect to one small member can be easily detached from each other by a simple rotation. At the same time, even when the two small members are separated from each other by rotation, the external members may not be attached to each other by the attraction force, and may be attached to other objects to which the coupling member is not attached. It is an object of the present invention to provide a rotary coupling member that can exert a force.

The above object of the present invention is achieved by a disk-like fixing member and a rotating member and a magnet which are coupled and separated from each other by sliding rotation.

The rotating coupling member provided with a magnet of the present invention includes a fixed member on a disc, a rotating member on a disc, and a magnet coupled to a central portion of the fixed member and a rotating member, and the fixed member and the rotating member face each other so that their centers coincide with each other. As long as the fixing member and the rotating member are coupled or detachable by the sliding rotation of the rotating member with respect to the fixing member in one state, the fixing member and the rotating member are separated by the magnetic force unless an external force is applied. There is a structural feature of the present invention to be attached to each other, look at each as follows.

The fixing member has a pair of "a" shaped cross-sections having a disk-shaped fixing plate fixedly attached to the surface of one side coupling object, and a horizontal portion facing the fixing plate center at the upper end of the vertical portions upright facing each other along the upper edge of the fixing plate. It consists of a fixed rail of.

The rotary member is laminated on the fixing member and the upper surface of the rotating plate of the disc is fixedly attached to the surface of the other coupling object, and the lower end of the vertical portion standing up to face each other along the inner side of the bottom edge of the rotating plate facing the upper surface of the fixing plate It consists of a pair of rotating rails having a "b" shaped cross section with a horizontal portion facing the outer side of the rotating plate.

At this time, the upper surface of the fixed rail and the lower surface of the rotating rail in the state in which the rotating member is laminated on the fixing member are always in contact with or opposed to the bottom surface of the rotating plate and the upper surface of the fixing plate, respectively. Accordingly, the whole or part of the horizontal portion of the rotary rail is located between the upper surface of the fixed plate and the bottom of the fixed rail horizontal portion or is completely out of the state.

That is, the rotating member is not separated from the fixing member in a state where all or part of the horizontal portion of the rotating rail is disposed between the upper surface of the fixing plate and the bottom of the fixing rail horizontal portion, but when the rotating member is completely deviated therebetween, The rotating member can be separated.

The magnet is a permanent magnet that is detachably fixed to the fixing plate upper surface of the fixing member and the center of the bottom surface of the rotating plate of the rotating member, and serves to couple the fixing member and the rotating member by magnetic force.

That is, even when the rotating member can be separated from the fixing member by completely releasing the rotating member between the upper surface of the fixing plate and the bottom of the fixing rail horizontal part, no external means is applied, and no coupling means is interposed between the fixing member and the rotating member. Although not, it is possible to maintain the bonded state, that is, attached state by the magnetic force.

At this time, the opposing surfaces of the two magnets respectively coupled to the centers of the fixed member and the rotating member should have different polarities, and in the case of one magnet, it may be replaced by a magnetic material such as a steel plate rather than a magnet.

Looking at the typical use of the subject innovation coupling member configured as described above are as follows.

First, the fixing member is fixedly coupled to one side of the rotating tip of the door, and the cam-type stopper is fixedly coupled to the rotating member, and then the rotating member is simply attached to the fixing member by using magnetic force.

When the door is closed while the long member of the cam stopper rotates the rotating member so that the rotating rail of the rotating member is positioned between the fixed plate and the fixed rail, the stopper coupled to the rotating member is disposed between the door and the frame. As a result of the pinch, a gap is formed between the door and the door frame, and as a result, a finger may be caught between the door and the door frame to prevent a safety accident from being injured.

The details of the purpose and technical constitution according to the present invention, including the effect thereof, will be clearly understood by the following description with reference to the drawings showing preferred embodiments of the present invention.

Example A cross-sectional view of a coupling of a rotating coupling member with a magnet is shown.

As shown, the rotating coupling member with a magnet of the present invention, the fixing plate 31A on the disc and the fixing plate center to the upper end of the vertical portion (V) upright so as to face along the upper edge of the fixing plate 31A. A fixing member 31 comprising a pair of fixing rails 31B having a “a” shaped cross section provided with a horizontal portion H;

Fixed rail when rotating on one end of the disk-shaped rotary plate 32A to which the upper surface is fixedly attached to the surface of the other side of the coupling object, and the vertical portion V 'upright so as to face along the inner side adjacent the bottom edge of the rotary plate 32A. A pair of rotary rails 32B having a "b" shaped cross section provided with a horizontal portion H 'facing outward of the rotating plate 32A so as to be interposed between the horizontal portion H of the 31B and the fixed plate 31A. And a rotating member 32 stacked on top of the fixing member 31;

It consists of a pair of magnets 33 which are detachably fixed to the center of the fixing plate 31A of the fixing member 31 and the center of the bottom surface of the rotating plate 32A of the rotating member 32, respectively.

Then, the bottom of the horizontal portion (H) of the fixed rail (31B) standing upright so as to face each other along the upper edge of the fixing plate (31A) facing the spaced apart from the upper surface of the fixing plate (31A), the bottom edge of the rotating plate (32A) The upper surface of the horizontal portion H 'of the rotary rails 32B, which are respectively erected so as to face along the inner side adjacent to each other, is also in a state of being opposed to the bottom of the rotary plate 32A, and the horizontal portion of the fixed rail 31B is rotated. (H) and the horizontal portion (H ') of the rotary rail 32B is a structure that may be completely overlapped up and down over the entire length, or may not overlap at all.

Further, the vertical portion V of the fixed rail 31B and the vertical portion V ′ of the rotary rail 32B, which are standing upright on the upper surface of the fixed plate 31A and the lower surface of the rotary plate 32A, respectively, are formed on two circular arcs concentric with each other. As it is located, the vertical portion V of the fixed rail 31B forms an outer concentric circular arc, and the horizontal portion H of the fixed rail 31B and the horizontal portion H 'of the rotary rail 32B are two concentric circles. Rotation between them overlaps or does not overlap each other.

At this time, the entire length of the fixed rail 31B and the rotary rail 32B is not larger than the circumference on the same circular arc, and the circular arc spacing between the fixed rails 31B is not shorter than the length of the rotary rail 32B. When the rotary member 32 is initially stacked on the fixed member 31, the rotary rail 32B is simply attached to each other by the attraction force of the magnets coupled to the respective centers while being positioned between the fixed rails 31B. .

When the rotating member 32 is rotated with respect to the fixing member 31 in the simple attachment state as described above, the horizontal portion H 'of the rotating rail 32B provided on the bottom surface of the rotating member 32 is fixed. The gap between the fixed plate 31A of the member 31 and the horizontal portion H of the fixed rail 31B enters into a gap, whereby the horizontal portion H 'and the horizontal portion of the fixed rail 31B of the rotary rail 32B. (H) overlaps up and down while being engaged with each other, that is, the rotating member 32 in the vertical direction with respect to the fixing member 31, in a state that cannot be separated from each other with respect to the external force.

In addition, the first stacked state of the fixing member 31 and the rotating member 32, that is, the horizontal portion H 'of the rotary rail 32B and the horizontal portion H of the fixed rail 31B do not overlap vertically. Is attached to the rotating member 32 without falling from the fixing member 31 by the magnetic force generated from a pair of magnets provided at each center of the fixing member 31 and the rotating member 32 In terms of manufacturing cost, one magnet may be replaced with a ferromagnetic material such as a steel sheet.

Rotating member according to the present invention configured as described above is capable of free rotation of the rotating member with respect to the fixed member, and while rotating the rotating member to generate a click sound while rotating the rotating member at the same time the horizontal member rather than the vertical direction In order to prevent the rotating member from rotating by itself due to its own use in the combined direction, as shown in FIG. 6, the upper surface of the fixed rail 31B horizontal part H or the lower surface of the rotating rail 32B horizontal part H ′. A plurality of locking projections (E) and a plurality of locking grooves (G) detachably coupled to either one of the surfaces and the bottom surface of the rotating plate (32A) or the upper surface of the fixed plate (31A) which are opposite thereto It is also preferable to form at regular intervals.

That is, by engaging the engaging projection (E) in the engaging groove (G), the rotation of the rotating member 32 itself can be prevented unless an external force is applied to the rotating member (32).

As shown in FIG. 7. The fixing member 31 of the present invention is fixedly attached to the door D, and the rotating member 32 is fixed to the rotating member 32 in a state in which a cam type stopper 34 having a long part and a short part is coupled. Can be coupled to the member 31, by rotating the rotating member 32 so that the long part of the stopper 34 protrudes out of the door (D), when the door (D) is closed, the door (D) and the door frame A gap can be formed between them.

That is, when the door is closed, the hand and the like can be prevented from being injured by the gap between the door and the door frame formed by the stopper (S).

As described above, the rotating coupling member provided with a magnet of the present invention is not only easy to manufacture due to its simple structure, but also can be easily rotated and maintained even by a detachable state by magnetic force, thereby causing a risk of loss. This lack of course has the advantage of easy replacement.
