Description

[0002] Inward-and-outward opening door systems

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a door system for opening and closing an opening provided in an opening for a person or the like in a building or an opening for lighting.

Various door systems are installed in the openings for people in buildings and the like and for openings for mining. The door system is classified into a door system of a sliding door type, a sliding door system, and a folding door system according to a manner in which a door opens and closes an opening. Where it is necessary to increase the opening rate, a door system of a hinged or folding type is often used.

However, according to the conventional example, the door system of the hinged type is configured such that the door is operated only in the outdoor direction or only in the indoor direction when the opening portion is opened. When the door is opened only in the outdoor direction when the opening is opened, the user can not cope with a situation in which the door must be operated in the indoor direction. Similarly, when the door is opened only in the direction of the room when the opening is opened, the user can not cope with a situation in which the door must be operated in the outdoor direction. Therefore, it may be inconvenient for the user to use the door. In addition, the door system of the hinged type has a problem that the door occupies a relatively large amount of outdoor or indoor space in a state in which it operates so as to completely open the opening, resulting in a low efficiency.

An object of the present invention is to provide a bi-directional open door system capable of operating in both outdoor and in-door directions in which the door is biased when the opening is opened, thereby enhancing convenience.

According to an aspect of the present invention, there is provided a bi-directional open door system comprising a door frame, two doors operable to open and close an interior space of the door frame, Lt; / RTI > link assemblies. Each of the link assemblies includes a first main link member, a second main link member, a first sub link member, a second sub link member, and a sliding unit. The first main link member is fixed to one side surface of one of the doors and has first and second end portions. The second main link member is fixed to one edge surface of the other door and has first and second end portions. The first sub link member is hinged to the first end of the first main link member in a state where the first sub link member is overlapped with the first main link member and the second end is hinged to the first end of the second main link member . The second sub link member is made to have the same length as the first sub link member and the first end overlaps with the second main link member on the opposite side of the first sub link member to the second end of the first main link member, And the second end is hingedly coupled to the second main link member. The sliding unit is mounted on the second main link member adjacent to the second end of the second sub link member and slidably supported on the door frame.

Further, the bidirectional open door system according to the present invention may include one door that operates to open and close the inner space of the door frame. Here, the first main link member has a length corresponding to a part of one of the edge surfaces of the door, and has first and second end portions. The second main link member is fixed to the other of the one side surface of the door and has first and second end portions.

According to the present invention, since the door can be opened and closed in both directions, convenience can be improved, and the opening ratio of the door can be maximized. According to the present invention, the door can be smoothly opened and closed by the balancing mechanism. Further, according to the present invention, the number of assembling steps of the door chassis constituting the door can be reduced, so that the door chassis can be easily assembled.

The present invention will now be described in detail with reference to the accompanying drawings. Here, the same reference numerals are used for the same components, and a detailed description of known functions and configurations that may unnecessarily obscure the gist of the present invention will be omitted. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

1 is an exploded perspective view of a bi-directional open door system in accordance with an embodiment of the present invention. Fig. 2 is an exploded perspective view showing the link assembly disposed on the lower side in Fig. 1; Fig. Figure 3 is a top view of the link assembly shown in Figure 2;

1 to 3, the bi-directional open door system includes a door frame 110, two doors 121, 122, and a pair of link assemblies 130.

The door frame 110 may be installed along an inner circumference of an opening of a building or the like. The door frame 110 may have a structure in which the horizontal frames 111 and the vertical frames 112 are connected to each other, thereby defining a rectangular internal space.

The two doors 121 and 122 are operated to open and close the inner space of the door frame 110. The doors 121 and 122 may each be a square. The doors 121 and 122 are arranged laterally in the inner space of the door frame 110 so that the inner space of the door frame 110 can be opened and closed laterally. The doors 121 and 122 may each be sized to completely close the interior space of the door frame 110 in a completely unfolded state.

Although the left door 121 is illustrated as having a narrower left and right width than the right door 122, the doors 121 and 122 may have different widths . ≪ / RTI > In addition, the doors 121 and 122 may be formed in various shapes such as glass fitted.

The pair of link assemblies 130 interlock with the doors 121 and 122 as they are folded or unfolded at both edges of the doors 121 and 122. Each of the link assemblies 130 includes a first main link member 131, a second main link member 132, a first sub link member 133, a second sub link member 134, and a sliding unit 135 ). The link assemblies 130 may be installed on the upper and lower sides of the doors 121 and 122 so as to be symmetrical to each other.

Hereinafter, a link assembly 130 installed below the doors 121 and 122 of the pair of link assemblies 130 will be described. The first end of the first main link member 131 corresponds to the left end and the second end of the first main link member 131 corresponds to the right end. Similarly, the first and second end portions of the second main link member 132 and the first and second sub link members 133 and 134 correspond to the left and right end portions, respectively.

The first main link member 131 is fixed to one side edge of one of the doors, for example, the lower surface of the left door 121. The first main link member 131 may be fixed to the lower surface of the left door 121 by a predetermined width along the lower surface of the left door 121.

The left end of the first main link member 131 may be hinged to the door frame 110. Of course, the left end of the first main link member 131 may be supported by the door frame 110 so as to be slidable. In this case, the left end of the first main link member 131 can be supported by the door frame 110 via the sliding unit of the same type as the sliding unit 135.

The second main link member 132 is fixed to one of the edge surfaces of the other door, for example, the lower surface of the right door 122. The second main link member 132 can be fixed to the lower surface of the right door 122 with a predetermined width extending along the lower surface of the right door 122. The second main link member 132 may have the same width as the width of the first main link member 131.

The first sub link member 133 is hinged to the left end of the first main link member 131 in a state where the first sub link member 133 is overlapped with the first main link member 131, To the left end of the hinged portion. The first sub link member 133 may have a narrower width than the first main link member 131.

The second sub link member 134 has the same length as that of the first sub link member 133. The second sub link member 134 is hinged to the right end of the first main link member 131 with its left end overlapped with the second main link member 132 on the opposite side of the first sub link member 133 And the right end is hinged to the second main link member 132. The second sub link member 134 has a narrower width than the second main link member 132 and can have the same width as the first sub link member 133. [

When the first sub link member 133 is disposed on the upper side of the first main link member 131, the second sub link member 134 may be disposed on the lower side of the second main link member 132. Of course, the first sub link member 133 may be disposed below the first main link member 131, and the second sub link member 134 may be disposed above the second main link member 132.

The sliding unit 135 is attached to the second main link member 132 adjacent to the right end of the second sub link member 134 and is slidably supported by the door frame 110. The sliding unit 135 may be coaxially hinged to the center of rotation of the right end of the second sub link member 134. The sliding unit 135 can be slidably guided by the guide groove 111a formed in the horizontal frame 111 of the door frame 110. [ The guide groove 111a may be formed long in the longitudinal direction on the inner surface of the horizontal frame 111 so that the guide groove 111a can slide laterally in a state in which the sliding unit 135 is accommodated. The guide groove 111a may have a narrow shape at the entrance so that the sliding unit 135 slides while being detached.

In one example, the sliding unit 135 may include a sliding body 135a hinged to the second main link member 132 and a pair of rollers 135b rotatably supported on the sliding body 135a have. The rollers 135b allow the sliding body 135a to smoothly slide laterally in the guide groove 111a. The rollers 135b are installed on the sliding body 135a so as to rotate along both inner walls with respect to the entrance of the guide groove 111a.

An example of the operation of the above-described bidirectional open door system will be described with reference to FIGS. 3 to 7. FIG. Here, it is assumed that the rear space of the door frame 110 is an outdoor space, and the front space of the door frame 110 is an indoor space.

3, when the user pulls the right door 122 to fully unfold the link assembly 130, the left door 121 is unfolded and unfolded, so that the door frame 110, together with the right door 122, Thereby completely closing the internal space.

4, when the user pushes the right door 122 rearward to fold the link assembly 130, the right door 122 rotates counterclockwise and slides leftward And the left door 121 rotates counterclockwise about a hinged portion of the door frame 110. [ Accordingly, the right space of the door frame 110 is opened and the space between the left door 121 and the right door 122 can be opened. 5, when the user pushes the right door 122 rearward as far as possible to fully fold the link assembly 130, the left and right doors 121, 122 are superimposed on each other so that the door frame 110 Can be completely opened.

6, when the user pulls the right door 122 forward and folds the link assembly 130, the right door 122 rotates clockwise and slides to the left, The left door 121 is rotated around a hinged portion of the door frame 110. [ Accordingly, the right space of the door frame 110 is opened and the space between the left door 121 and the right door 122 can be opened. 7, when the user pulls the right door 122 forward as far as possible to fully fold the link assembly 130, the left and right doors 121 and 122 are folded together and the door frame 110 Can be completely opened.

In this way, when the inner space of the door frame 110 is opened, the doors 121 and 122 can operate in both the outdoor direction and the indoor direction in both directions, thereby enhancing convenience. Further, when the inner space of the door frame 110 is fully opened, the first and second main link members 131 and 132 are vertically rotated to be folded to each other, so that the left and right doors 121 and 122 All of the front and rear surfaces of the door frame 110 can be folded vertically. Accordingly, the opening rate for opening the inner space of the door frame 110 can be maximized while occupying less space in front of or behind the door frame 110. [

Meanwhile, as shown in Figs. 8 and 9, the bi-directional open door system may further include a balancing mechanism 140. Fig. The balancing mechanism 140 is configured such that the sliding unit 135 of the upper link assembly 130 and the sliding unit 135 of the lower link assembly 130 move at the same amount of movement when the doors 121 and 122 are opened and closed . Therefore, the doors 121 and 122 can smoothly open and close.

The balancing mechanism 140 according to the first example may include rotating shafts 141, planetary gear assemblies 142, and rack gears 143a, 143b. The rotating shafts 141 are rotatably coupled to the sliding units 135, respectively, and a pinion gear 141a is formed around each of the rotating shafts 141. The rotating shafts 141 can be connected by a connecting bar 144 passing through the right door 122. The connecting bar 144 may be in the form of a rod.

The planetary gear assemblies 142 transmit the rotational force of the right door 122 to the rotating shafts 141. The planetary gear assembly 142 includes a sun gear 142a, a ring gear 142b, a planetary gear 142c, and a carrier 142d. The sun gear 142a is coaxially fixed to the rotating shaft 141. [ The ring gear 142b is fixed to the right door 122. The planetary gears 142c are arranged along the circumference of the sun gear 142a between the sun gear 142a and the ring gear 142b. The respective planetary gears 142c are engaged with the sun gear 142a and the ring gear 142b. The carrier 142d supports the planetary gears 142c. The rotational force of the right door 122 is transmitted to the sun gear 142a via the ring gear 142b and the planetary gear 142c so that the rotation shaft 141 can be rotated by the rotation of the sun gear 142a .

The rack gears 143a and 143b selectively engage with the respective pinion gears 141a in accordance with the opening / closing operation direction of the right door 122 and are respectively supported by an elastic force. The rack gears 143a and 143b can be supported by elastic members (not shown) such as springs on both sides of the pinion gear 141a in the door frame 110. [

10, when the user pushes the right door 122 rearward and opens the pinion gear 141a, the pinion gear 141a meshes with the rack gear 143a on the indoor side and rotates in the counterclockwise direction, Thereby allowing the shaft 141 to move to the left. 11, when the user pulls the right door 122 forward and opens the pinion gear 141a, the pinion gear 141a meshes with the rack gear 143b on the outdoor side and rotates in the clockwise direction, ) To the left. At this time, the rotating shafts 141 are restricted to move by the same amount of movement to each other by the planetary gear assemblies 142 and the rack gears 143a, 143b. Therefore, the sliding units 135 connected to the rotating shafts 141 can move left and right with the same amount of movement.

12, the balancing mechanism 240 according to the second example may include a guide gear 241, and an interlocking member 242. [ The guide gear 241 is rotatably supported within the door frame 110. The guide gear 241 may be disposed in the vertical frame 112.

One of the interlocking members 242 is connected to the sliding unit 135 of the upper link assembly 130 and the other is connected to the sliding unit 135 of the lower link assembly 130. [ The interlocking members 242 are guided to move along the door frame 110 within the door frame 110. The interlocking members 242 are configured to be deformed when moving along a corner portion of the door frame 110. The interlocking member 242 may be made of a metal material having elasticity at the deformation portion. The interlocking members 242 may be connected by a connecting bar 243 passing through the right door 122.

The interlocking members 242 have gears 242a that engage with the guide gear 241 with the guide gear 241 interposed therebetween. The interlocking members 242 are restricted by the guide gear 241 to move at the same moving amount with respect to each other. Therefore, the sliding units 135 connected to the interlocking members 242 can move left and right with the same amount of movement.

13, the balancing mechanism 340 according to the third example includes a shifting member 341, a screw member 342, a first bevel gear 343, a second bevel gear 342, 344, and an interlocking shaft 345. One of the shifting members 341 is connected to the sliding unit 135 of the upper link assembly 130 and the other is connected to the sliding unit 135 of the lower link assembly 130. The movable members 341 may be connected by a connecting bar 346 passing through the right door 122.

The screw members 342 are disposed side by side in the door frame 110 in a state where they are screwed to the moving members 341, respectively. The screw members 342 are rotatably supported in the horizontal frame 111 on the upper and lower sides about the horizontal axis. The first bevel gears 343 are coaxially fixed to the screw members 342, respectively. The second bevel gears 344 are engaged with the first bevel gears 343, respectively. The first and second bevel gears 343 and 344 are disposed at the corners of the door frame 110.

The interlocking shaft 345 is coaxially fixed to both ends of the second bevel gears 344 and disposed in the door frame 110. When the link assemblies 130 are arranged up and down, the interlocking shaft 345 is rotatably supported in the longitudinal frame 112. [ The first bevel gears 343 are constrained to move with the same amount of movement of the shifting members 341 while being engaged with the second bevel gears 344 so that the sliding unit 135 connected to the shifting members 341, Can move left and right with the same amount of movement.

14, the balancing mechanism 440 according to the fourth example includes belts 441, first pulleys 442, second pulleys 443, and interlocking shafts 444 . One belt 441 runs between the upper first pulley 442 and the second pulley 443 while being connected to the sliding unit 135 of the upper link assembly 130. [ The other belt 441 is spanned between the lower first pulley 442 and the second pulley 443 while being connected to the sliding unit 135 of the lower link assembly 130. [ The belts 441 rotate as the sliding units 135 slide. The belts 441 may be connected by a connecting bar 445 passing through the right door 122.

The first pulley 442 rotatably supports one side of each belt 441. The first pulleys 442 are coaxially fixed to both ends of the interlocking shaft 444, respectively. The second pulleys 443 are spaced apart from the first pulleys 442 and rotatably support the other side of each belt 441. The second pulleys 443 are rotatably supported about the vertical axis in the upper and lower horizontal frames 111. The interlocking shaft 444 is disposed within the door frame 110. When the link assemblies 130 are arranged up and down, the interlocking shaft 444 is rotatably supported within the longitudinal frame 112. Since the belts 441 are restricted to move at the same moving amount with respect to each other, the sliding units 135 connected to the belts 441 can move to the left and right at the same moving amount.

15 to 17, the bi-directional open door system may further include a braking mechanism 150 for braking the sliding units 135. For example, the braking mechanism 150 includes the fixed blocks 151, the compression blocks 152, the rotation lever 153, the gear 154 for the lever, and the actuating member 155.

The fixed blocks 151 are moved in such a manner as to be in close contact with or disengaged from the sliding units 135 in the horizontal frame 111 of the door frame 110 while being supported by the elastic force. The fixing blocks 151 are subjected to elastic force by elastic members (not shown) in the direction of approaching the pressing blocks 152. The fixed blocks 151 are formed with first protrusions 151a at regular intervals on opposite surfaces facing the sliding units 135. [ The first projections 151a may each be formed in a trapezoidal shape.

The fixed blocks 151 may have a concavo-convex structure on the side facing the sliding units 135. [ Therefore, the braking effect can be enhanced when the fixed blocks 151 are in close contact with the rollers 135b of the sliding units 135. [

The pressing blocks 152 are formed with the second protrusions 152a in such a size that they can be inserted between the first protrusions 151a on the respective surfaces facing the fixing blocks 151, respectively. The second projections 152a may each be formed in a trapezoidal shape. The pressing blocks 152 press or release the fixing blocks 151 in accordance with the slide reciprocating motion in the horizontal frame 111.

17, the push block 152 presses the fixed block 151 when the second protrusions 152a slide to correspond to the first protrusions 151a, respectively. Accordingly, the fixing block 151 can move so as to be in close contact with the roller 135b of the sliding unit 135. [ 16, when the second pushing portions 152a are slidably inserted between the first pushing portions 151a, the pushing block 152 releases the pushing block 151 from the pushed state . Thus, the fixing block 151 can be released from the state of being in tight contact with the roller 135b of the sliding unit 135. [ At this time, the fixing block 151 maintains the state where the second protrusions 152a of the compression block 152 are inserted between the first protrusions 151a by the elastic force of the elastic member.

The rotary lever 153 is disposed outside the door frame 110 and rotates. The rotation lever 153 may be disposed in the vertical frame 112. The lever gear 154 is coaxially fixed to the rotary lever 153 in the door frame 110 and rotates together with the rotary lever 153.

The actuating members 155 are connected to the push blocks 152, respectively. The actuating members 155 have gears 155a that engage with the gears 154 for levers, respectively, via gears 154 for levers. The actuating members 155 slide back and forth the pushing blocks 152 in accordance with the forward and reverse rotation of the rotary lever 153. The actuating members 155 are guided to move along the door frame 110 within the door frame 110. The actuating members 155 are configured to be deformed when moving along the corner portion of the door frame 110. The operating member 155 may be made of a metal material having elasticity at the deformation portion.
