Description

Technical Field

[0001] This invention relates to door frames for buildings, and more particularly to a combination door for a two-way door and its door frame components. Background Technology

[0002] Traditional door frame components sold on the market are installed in buildings to provide a door panel for use as a door frame. This door frame only provides the door panel to open in one direction. This one-way opening function is insufficient to meet the requirements of opening and closing the building door panel in either direction, especially the need for fire escape.

[0003] Furthermore, related technologies of the inventors, such as Chinese Patent Publication No. CN105849351A and Chinese Patent Publication No. CN204040775U, disclose a two-way door with a two-way door closer structure. The operator is located on both sides of the door frame and pushes the door to open the door leaf. On one side, because the first hinge is installed to rotate only in the first direction, the middle frame and the door leaf relative to the inner edge of the large frame can only rotate back and forth in the first direction to open and close. On the other side, the second hinge is installed to rotate only in the second direction, so the door leaf relative to the inner edge of the middle frame can only rotate back and forth in the second direction to open and close.

[0004] The opening of the aforementioned door is limited to one direction by the hinges. The operator can only push the door open in one direction from either side of the door frame. However, in addition to the instinctive action of pushing (instead of pulling) the door when faced with an emergency-closed door, unpredictable situations may arise where the escapee unconsciously pulls the door to escape, or the escapee may act on instinct. Therefore, enabling the door frame to open and close in both directions, allowing the escapee to pull or push the door from either side of the door frame, and closing the door for fire prevention, has become a necessary and further demanded safety task. Summary of the Invention

[0005] To overcome the aforementioned problems of the prior art, the present invention provides a door frame assembly that can be pushed or pulled open from either side, which can be used in conjunction with a door leaf to form a unique combination door with two frames and one leaf, which is essentially a frame and two leaves. At the same time, it utilizes a two-way door closer to manage the functions of two one-way opening door leaves, and employs a novel lock control configuration, so that the door frame can be opened by pulling or pushing from either side for escape and closed for fire prevention.

[0006] The present invention relates to a combination door and its door frame assembly that can be pushed or pulled open from either side, comprising: a large frame including an inner frame stop and a first receiving opening, and a first crossbeam on its upper side; a middle frame for supporting a door leaf; the door leaf rotating in a second direction; a first lock engaged with the middle frame (e.g., a lock engaged with a through groove in the middle frame), the first lock further including a first handle connected to a first movable tongue in the middle frame, the first movable tongue being telescopically protruding from one outer edge of the middle frame; and a first hinge, one side of the first hinge being connected to the large frame and the other side to the middle frame, the first hinge being installed in a first direction. Rotation; the first movable tongue is used to movably engage or disengage from the first receiving opening, and the middle frame is used to movably engage or disengage from the large frame stop; the middle frame includes an inner middle frame stop and an outer middle frame guard plate extending therefrom, the middle frame guard plate being used to detachably cover the large frame stop; a two-way door closer includes a body, a first sliding arm, and a second sliding arm, the body being engaged with the middle frame, one side of the first sliding arm being movably engaged with the body, and the other side being movably engaged with the first crossbeam, and one side of the second sliding arm being movably engaged with the body, thereby being prepared for use with a door leaf, and serving as a door frame assembly that can be pushed or pulled open from either side.

[0007] In one embodiment of the door frame assembly of the present invention, which can be pushed or pulled open from either side, the first handle is used to drive the first movable tongue to movably engage or disengage from the first receiving opening. The first handle is used to drive the first movable tongue to disengage from the first receiving opening. The first handle pulls the middle frame away from the large frame stop, forming the middle frame that opens in a first direction. This serves as a door frame assembly that can be pushed or pulled open from either side. It can be used in conjunction with a door leaf and a locking device to meet the requirements of opening and closing a building door frame from either direction, especially addressing the need for fire escape.

[0008] Therefore, in some embodiments of the door frame assembly of the present invention, which can be pushed or pulled open from either side, a door leaf assembly is provided with a lock to control the door leaf to be opened and closed in conjunction with the middle frame, or the combined door to be opened and closed in conjunction with the large frame; and the other side of the second sliding arm of the two-way door closer is movably connected to the door leaf, forming a three-in-one structure including two frames and one leaf, which is essentially a unique combined door structure of one frame and two leaves. At the same time, by utilizing a two-way door closer to manage the functions of two unidirectional opening door leaves, and by using a novel locking configuration, the present invention is not limited to the problem that traditional two-way doors can only be opened unidirectionally from either side of the door frame. The combined door and door frame assembly of the present invention, which can be pushed or pulled open from either side, can arbitrarily open the door in both directions for escape and close the door for fire prevention.

[0009] An embodiment of the combined door and its door frame assembly that can be pushed or pulled open from either side of the present invention further includes a second hinge, one side of which is connected to the middle frame and the other side of which is connected to one side of the door leaf. The second hinge is installed to rotate in a second direction. The other side of the second sliding arm of the two-way door closer is movably connected to the door leaf. The inner edge of the middle frame also includes a second receiving opening. The door leaf includes a second lock, which further includes a second handle connected to a second movable tongue that can extend and retract beyond the outer edge of the other side of the door leaf. The second movable tongue can movably engage with or disengage from the second receiving opening.

[0010] The second handle is used to drive the second movable tongue away from the second receiving opening, so that the user, located on the first side of the door frame, can push the door leaf away from the middle frame stop to form a door leaf that opens in the second direction, allowing the user to push and walk away or escape in case of fire.

[0011] An embodiment of the present invention provides a combination door and its door frame assembly that can be pushed or pulled open from either side. The second handle is used to drive the second movable tongue to extend and engage with the second receiving opening. The door leaf and the middle frame are combined to form a single combination door. By operating the first handle, the first movable tongue is driven away from the first receiving opening. Thus, the user, located on one side of the door frame in a first direction, can pull the first handle to drive the middle frame and the door leaf, forming a combination door that opens in the first direction. The user can immediately pull and leave or escape in case of fire.

[0012] The aforementioned large frame stop is used to abut against the middle frame. Due to the large frame stop obscuring part of the middle frame (the headrest) in front of the barrier, the middle frame is too narrow to install ordinary locks or handles. In one embodiment of the door frame assembly of the present invention, the door frame assembly further includes an actuating lock group, which includes a third handle, a third movable tongue, and a roller drive plate. The middle frame also includes a third receiving opening. The third handle is located on the other side of the door leaf relative to the first handle. The third movable tongue is telescopically extended out of the outer edge of one side of the door leaf. One side of the roller drive plate is connected to the free end of the first handle of the first lock in the third receiving opening of the middle frame. The other side of the roller drive plate has a roller that can movably extend out of the third receiving opening and is adjacent to the third movable tongue.

[0013] In this way, the user operates the third handle to drive the third movable tongue to protrude from the outer edge of the door leaf, press and push the roller to move the roller drive plate, thereby driving the first movable tongue to retract and unlock at the outer edge of the middle frame. This pushes the door leaf and the middle frame together away from the large frame stop in the second direction of the door frame, forming a combination door that opens in the first direction. The user can push and walk away immediately or escape in case of fire. This overcomes the problem that it is difficult to install ordinary locks or handles due to the large frame stop blocking part of the middle frame (head) in front of the barrier. It achieves the integration of the door leaf and the middle frame. The combination door that opens in the first direction is formed by unlocking relative to the large frame stop, or by releasing the third handle to release the first movable tongue to rejoin the first receiving opening of the large frame, forming a composite combination door with the door leaf, middle frame and large frame as one.

[0014] In one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side include a fourth handle on the side of the door leaf opposite to the second handle. The fourth handle and the second handle are coaxially connected, thereby the fourth handle can also drive the second movable tongue to extend retractably out of the outer edge of the door leaf, so that the second movable tongue can movably engage with or disengage from the second receiving opening. Thus, when the user is located on the second direction side of the door frame assembly, he can pull the door leaf away from the middle frame stop to form a door leaf that opens in the second direction, allowing the user to pull and leave immediately or escape in case of fire. Compared to existing technologies where the door leaf connected to the door frame assembly can only be opened in one direction from one side of the door frame, the door frame assembly of the present invention, which can be pushed or pulled open from either side, provides a door frame structure that can be combined with a door leaf to form a combined door structure. At the same time, it utilizes a two-way door closer to manage the functions of two door leaves that can be opened in one direction. With the use of a novel lock control configuration, the present invention is not limited to the problem that the door leaf of the traditional two-way door can only be opened in one direction from one side of the door frame. The combined door and door frame assembly of the present invention, which can be pushed or pulled open from either side, can open the door in any two directions for escape and close the door for fire prevention.

Detailed Implementation

[0017] To enable your review committee to gain a better understanding and appreciation of the features and characteristics of this invention, the following preferred embodiments are provided in conjunction with the accompanying drawings: Please refer to Figures 1 to 6As shown, the present invention relates to a combination door and its door frame assembly that can be pushed or pulled open from either side, comprising: a large frame 2, the large frame 2 including a large frame stop 23 and a first receiving opening 24 formed on the inner side, and a first crossbeam 25 on the upper side; a middle frame 3; a first lock 32 attached to the middle frame 3 (for example, in the prior art, a through groove can be opened inside the middle frame 3 to install the lock), the first lock 32 also including a first handle 34 connected to a first movable tongue 36 inside the middle frame 3, the first movable tongue 36 being telescopically protruding from the middle frame 3. The outer edge of one side of frame 3; a first hinge 4, one side of which is connected to the large frame 2 and the other side of which is connected to the middle frame 3, the first hinge 4 being installed to rotate in the first direction S1; a first movable tongue 36 for movably engaging or disengaging from the first receiving opening 24, and the middle frame 3 for movably engaging or disengaging from the large frame stop 23; the middle frame 3 includes a middle frame stop 30 formed on its inner side, and a middle frame guard plate 33 extending from its outer side, the middle frame guard plate 33 being detachably used to cover the large frame stop 23; The two-way door closer 7 includes a body 71, a first sliding arm 73, and a second sliding arm 75. The body 71 is attached to the middle frame 3. The first sliding arm 73 is movably attached to the body 71 on one side and movably attached to the first crossbeam 25 on the other side. The second sliding arm 75 is movably attached to the body 71 on one side. Thus, it can be prepared for use with a door leaf and serve as a door frame assembly that can be pushed or pulled open from either side.

[0018] Please also refer to Figure 1 , Figure 3 , Figure 6 As shown, in one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side, the first handle 34 is used to drive the first movable tongue 36 to movably engage or disengage from the first receiving opening 24. The first handle 34 is used to drive the first movable tongue 36 to disengage from the first receiving opening 24. The first handle 34 pulls the middle frame 3 away from the large frame stop 23, forming the middle frame 3 that opens in the first direction S1. Thus, as a door frame assembly that can be pushed or pulled open from either side, it can be used to combine a door leaf and a locking device to meet the requirements of opening and closing the building door in either direction, especially the need for fire escape.

[0019] Therefore, in some embodiments of the door frame assembly of the present invention, which can be pushed or pulled open from either side, a door leaf assembly is equipped with a lock to control the door leaf 5 to be opened and closed in connection with the middle frame 3, or the combined door to be opened and closed in connection with the large frame 2; and the other side of the second sliding arm 75 of the two-way door closer 7 is movably connected to the door leaf 5, forming a three-in-one structure including two frames and one leaf, which is essentially a unique combined door structure of one frame and two leaves. At the same time, the two-way door closer manages the functions of two unidirectional opening door leaves, and the novel lock configuration allows the door frame to be opened for escape by pulling or pushing in any two directions and to close for fire prevention.

[0020] Please also refer to Figure 1 , Figure 4 , Figure 5 As shown, an embodiment of the combined door and its door frame assembly of the present invention, which can be pushed or pulled open from either side, further includes a door leaf 5 and a second hinge 6. One side of the second hinge 6 is connected to the middle frame 3, and the other side of the second hinge 6 is connected to one side of the door leaf 5. The second hinge 6 is installed to rotate in a second direction S2. The other side of the second sliding arm 75 of the bidirectional door closer 7 is movably connected to the door leaf 5. The inner edge of the middle frame 3 also includes a second receiving opening 38. The door leaf 5 includes a second lock 52. The second lock 52 also includes a second handle 54 connected to a second movable tongue 55 that can extend and retract out of the outer edge of the other side of the door leaf 5. The second movable tongue 55 can movably engage with or disengage from the second receiving opening 38.

[0021] In one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side, the second handle 54 is used to drive the second movable tongue 55 away from the second receiving opening 38, thereby allowing the user, located on the first direction S1 side of the door frame, to push the door leaf 5 away from the middle frame stop 30, forming a door leaf 5 that opens in the second direction S2, allowing the user to push and leave immediately or escape in case of fire.

[0022] Please also refer to Figures 3 to 6 As shown, in one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side, the second handle 54 is used to drive the second movable tongue 55 to protrude and engage with the second receiving opening 38. The door leaf 5 and the middle frame 3 are combined to form a single combination door. By operating the first handle 34, the first movable tongue 36 is driven away from the first receiving opening 24. Thus, the user, located on the first direction S1 side of the door frame, can pull the first handle to drive the middle frame 3 and the door leaf 5, forming a combination door that opens the middle frame 3 and the door leaf 5 in the first direction S1. The user can immediately pull and leave or escape in case of fire.

[0023] Please also refer to Figures 2 to 6 As shown, the aforementioned large frame stop 23 has the structural function of being able to abut against the middle frame 3 or for the middle frame 3 to drive the door leaf 5 to open in the second direction S2. It also has basic anti-theft and aesthetic purposes. However, due to the large frame stop 23 blocking part of the middle frame 3 (head bumping), the middle frame 3 is too narrow to install ordinary locks or handles. This creates a problem with the function of unlocking the large frame stop 23 when operating the door leaf 5 and the middle frame 3 as a whole. Therefore, it is necessary to design a special lock to solve this limitation problem of the door frame component.

[0024] Please also refer to Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figures 10 to 13 As shown, an embodiment of the combined door and its door frame assembly of the present invention, which can be pushed or pulled open from either side, further includes an actuated lock assembly 50, which includes a third handle 57, a third movable tongue 571, and a roller drive plate 59; the middle frame 3 also includes a third receiving opening 31, the third handle 57 is disposed on the other side of the door leaf 5 opposite to the first handle 34 and connected thereto, the third movable tongue 571 is telescopically protruding from the outer edge of one side of the door leaf 5, one side of the roller drive plate 59 is coaxially connected to the free end of the first handle 34 of the first lock 32 within the third receiving opening 31 of the middle frame 3, and the other side of the roller drive plate 59 has a roller 591 that movably extends out of the third receiving opening 31 and is adjacent to the third movable tongue 571.

[0025] In one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side, the user operates the third handle 57 to drive the third movable tongue 571 to protrude from the outer edge of the door leaf 5, pressing and pushing the roller 591 to move the roller drive plate 59, thereby driving the first movable tongue 36 to retract and unlock at the outer edge of the middle frame 3. This pushes the door leaf 5 and the middle frame 3 together away from the large frame stop 23 in the second direction S2 of the door frame, forming a combination door that opens in the first direction S1, allowing the user to push, pull, or open the door. This allows for easy departure or fire escape, overcoming the problem that the middle frame 3 (bumper) is partially obscured by the large frame stop 23, making it difficult to install ordinary locks or handles. It achieves the integration of the door leaf 5 and the middle frame 3, which can be unlocked relative to the large frame stop 23 to form a combination door that opens in the first direction S1, or the third handle 57 can be released to release the first movable tongue 36 to return to the first receiving opening 24 of the large frame 2, forming a combination door where the door leaf 5 and the middle frame 3 are integrated and temporarily fixed to the large frame 2 to form a composite combination door frame, which is in the default closed state.

[0026] With this, the user is positioned on the second direction S2 side of the door frame. The user can operate the third handle 57 to drive the third movable tongue 571 to protrude from the outer edge of the door leaf 5, thereby pressing and pushing the roller 591. This, in turn, drives the roller drive plate 591 to drive the first movable tongue 36 to retract and unlock away from the first receiving opening 24 at the outer edge of the middle frame 3. The third handle 57 can then be pushed to move the door leaf 5 and the middle frame 3 together, forming a combined door that opens in the first direction S1. The user can then push and walk away or escape in case of fire.

[0027] Please also refer to Figure 2 , Figure 6 , Figures 9 to 14As shown, in one embodiment of the present invention, a combination door and its door frame assembly that can be pushed or pulled open from either side, wherein the third handle 57 is replaced by a third lock 500, the third lock 500 further including a keyhole 501 and a key 503, the third lock 500 being connected to the third movable tongue 571, the key 503 being used to engage with the keyhole 501, and operating the third lock 500 causing the third movable tongue 571 to extend retractably outward from the outer edge of one side of the door leaf 5, thereby pushing the roller 591 and the roller drive plate 59 to move up and down, thereby driving the first movable tongue 36 in the middle. The outer edge of frame 3 protrudes or retracts to engage with or disengage from the first receiving opening 24 of the large frame 2. This allows the user to be positioned on the second direction S2 side of the door frame. The user can use the key 503 to engage with the keyhole 501 and rotate it to operate the third movable tongue 571 of the third lock 500, which presses against and pushes the roller 591. This, in turn, drives the roller drive plate 59 to move the first movable tongue 36 away from the first receiving opening 24, thus pushing the third handle 57 to integrate the door leaf 5 and the middle frame 3, forming a combined door that opens in the first direction S1. The user can then easily push and leave or escape in case of fire. The key 503 of the third lock 500 has the same function as the third handle 57, and it engages the third movable tongue 571. Those skilled in the art will understand and use this function without further explanation.

[0028] Please also refer to Figure 1 , Figure 2 , Figures 4 to 9 As shown, in one embodiment of the combined door and its door frame assembly that can be pushed or pulled open from either side of the present invention, the door leaf 5 further includes a fourth handle 56 on the side opposite to the second handle 54. The fourth handle 56 and the second handle 54 are coaxially connected, for example, one side of the fourth handle 56 and the free end side of the second handle 54 are coaxially connected. In this way, the fourth handle 56 can also drive the second movable tongue 55 to extend retractably out of the outer edge of the door leaf 5, so that the second movable tongue 55 can movably engage with or disengage from the second receiving opening 38. Those skilled in the art will understand and use that the fourth handle 56 and the second handle 54 are coaxially connected, so that when the user is on the second direction S2 side of the door frame assembly, operating the fourth handle 56 can also drive the second movable tongue 55 to movably disengage from the second receiving opening 38. The door leaf 5 can be pulled away from the middle frame stop 30 to form a door leaf that opens in the second direction S2, allowing the user to pull and leave immediately or escape in case of fire.

[0029] Please also refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7As shown, in one embodiment of the combined door and its door frame assembly that can be pushed or pulled open from either side of the present invention, the first sliding arm 73 of the bidirectional door closer 7 further includes a first front end 731 and a first rear end 733; the second sliding arm 75 further includes a second front end 751 and a second rear end 752; the first crossbeam 25 includes a first sliding groove 251, which is located, for example, on one side of the first crossbeam 25; the first front end 731 of the first sliding arm 73 is rotatably connected to the upper side of the body 71, and its first rear end 733 is slidably connected to the first sliding groove 251; the door leaf 5 includes a second sliding groove 53, which is located, for example, on one side of the door leaf 5; the second front end 751 of the second sliding arm 75 is rotatably connected to the lower side of the body 71, and its second rear end 752 is slidably connected to the second sliding groove 53.

[0030] In some embodiments, the body 71 of the bidirectional door closer 7 can be hidden inside the middle frame 3, the first slide groove 251 can be formed inside the first crossbeam 25, or the second slide groove 53 can be formed inside the door leaf 5. Those skilled in the art will understand and apply this without further explanation.

[0031] The inventors also referenced their previous patent applications, Chinese Patent Publication No. CN105849351A and Chinese Patent Publication No. CN204040775U, which disclosed a two-way door with a two-way door closer structure. The patent applications and published references are incorporated herein by reference in their entirety, including the door closer described in the claims, drawings and embodiments, to further provide a detailed description of the technical solution of the present invention's combined door and its door frame components.

[0032] Please also refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, in one embodiment of the combination door and its door frame assembly that can be pushed or pulled open from either side of the present invention, the middle frame 3 includes an auxiliary lock 39, which also includes a handle 390 that can be linked to a movable tongue 391; the large frame 2 includes an auxiliary receiving opening 29 formed on its inner side, and the handle 390 of the auxiliary lock 39 rotates to link the movable tongue 391 to engage with the auxiliary receiving opening 29 in the large frame 2, so as to lock the middle frame 3 and the combined door leaf 5 together in the large frame 2, thereby controlling the access control of the door leaf 5 combined with the middle frame 3.

[0033] The handle 390 can be replaced with a key (not shown in the figure). Those skilled in the art will understand and use it without further explanation. The key is used to engage with the key. When the auxiliary lock is opened, the first movable tongue 391 is telescopically extended out of the outer edge of the middle frame 3 and engages with the auxiliary receiving opening 29 in the large frame 2 to lock the middle frame 3 and the door leaf 5 together in the large frame 2. Those skilled in the art will understand and use it without further explanation.

[0034] To enable the esteemed examiner to gain a deeper understanding and appreciation of the features and characteristics of this invention, the inventors have incorporated, in particular, the complete and detailed technical solutions of the present invention—including Chinese Patent Publication No. CN105849351A and Chinese Patent Publication No. CN204040775U, which disclose a two-way door with a two-way door closer structure—as well as the patent applications and published references, into this application. This will further provide a detailed description of the technical solutions of the present invention, including the combined door and its door frame components.

[0035] The door frame assembly of the present invention, which can be pushed or pulled open from either side, provides a combination door structure formed by combining a door leaf.
