Discussion of Related Art
Korean Utility Model number 20-0228474 discloses “a double window assembly with improved safety”, wherein an inner window is configured to act as a sidling window and an outer window is configured to act as a hinge type window. However, such a type of the double window assembly may lead to a high production cost due the fact that the inner and outer windows are separately provided. Further, such a type of the double window assembly may require a large installation space.
Further, Korean Patent application publication No. 10-2015-0038763 discloses a double hung window having a double glazing structure to apply a double glazing structure to a double hung window in the indoor and outdoor sides of a window frame, thereby preventing dew condensation and having improved heat insulation performance. To achieve this, the double hung window having a double glazing structure comprises: a window frame; a first double hung window installed in the indoor side of the window frame to be opened or closed; and a second double hung window installed in the outdoor side of the window frame at a space from the first double hung window to be opened or closed. According to the present invention, the double hung window having a double glazing structure prevents dew condensation and has improved heat insulation performance by applying a double glazing structure to the indoor and outdoor sides of a window frame. In addition to this, the double hung window having a double glazing structure can control the flow of air intake through a space between the first and second double hung windows in accordance with the solar radiation change and outdoor air conditions as the first and second double hung windows are separated from each other at a predetermined space to form a double glazing structure. Such a type of the double window assembly may have the shortcoming that the window space is not completely open.

The rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure may include an upper window 4, a lower window 5, a guide chassis 2, a rotatable chassis 3, and a housing 1.
In the housing 1, the guide chassis 2 and rotatable chassis 3 are disposed. The guide chassis 2 is positioned over the rotatable chassis 3. Further, the guide chassis 2 may be coupled to the upper window 4. The rotatable chassis 3 may be coupled to the lower window 5. The guide chassis 2 and rotatable chassis 3 may be made of the same material as that of a conventional window frame to support the windows. Thus, the housing 1, guide chassis 2, and rotatable chassis 3 may be made of, for example, aluminum, a synthetic resin, etc.
The housing 1 may refer to a rectangular frame having an inner rectangular space defined therein. The housing 1 may have first opposite holes 11 formed at an inner lower portion of the housing in both opposite inner side walls of the housing respectively. The extension line between the first opposite holes 11 may act as the rotation axis of the rotatable chassis 3. For this reason, the first opposite holes 11 may be preferably positioned at the lowest level of the inner side walls of the housing. The guide chassis 2 and rotatable chassis 3 may be received in and fitted with the inner space in the housing 1.
The guide chassis 2 may be coupled to the upper portion of the housing 1. The rotatable chassis 3 may be coupled to the lower portion of the housing 1. A length of each of the guide chassis 2 and rotatable chassis 3 may correspond to ½ of a total vertical length of the inner space of the housing 1. However, the present disclosure may not be limited thereto. For example, in order to improve the safety, the rotatable chassis 3 may have a longer vertical length that that of the guide chassis 2. This configuration results in a step between the upper window 4 and lower window 5 when the upper window 4 and lower window 5 overlaps each other. This step may allow a fixing of the upper window 4 and lower window 5 using a locker bar 52 or cover 36 as described later when the rotatable chassis 3 has rotated to the horizontal orientation.
Each of the guide chassis 2 and rotatable chassis 3 may have one open side. The guide chassis 2 and rotatable chassis 3 may have a tilted or rounded tilted ends at the contacting portions thereof. This may facilitate the rotation of the rotatable chassis 3. The guide chassis 2 may be fixed to the housing 1 at the upper portion thereof. The guide chassis 2 may have guide grooved lines 21 vertically defined at opposite inner side walls thereof respectively. The rotatable chassis 3 may have hinge protrusions 34 formed on opposite outer side walls thereof respectively so as to be received in the first opposite holes 11 of the housing 1 respectively.
In this way, the guide chassis 2 may be fixed to the housing 1. The rotatable chassis 3 may rotate via the hinge protrusion 34 from the housing 1.
The guide chassis 2 may have the guide grooved lines 21. The guide grooved lines 21 may respectively receive guide protrusions 41 formed on opposite outer side walls of the upper window 4 respectively. The upper window 4 may be fitted into the guide chassis 2. The upper window 4 may be made of a transparent material such as a glass, acryl, etc. Thus, a sliding of the guide protrusions 41 in and along the guide grooved lines 21 may guide the upper window 4 along the guide lines 21.
The rotatable chassis 3 may have the hinge protrusions 34 to be received in the first opposite holes 11 defined in the housing 1 respectively. The rotatable chassis 3 may have an inner space defined therein to receive the lower window 5. The lower window 5 may not have the guide protrusions. The lower window 5 may be fixed to the rotatable chassis 3.
The housing 1 may have the inner accommodation space to receive the guide chassis 2, and rotatable chassis 3, which receives the upper window 4 and lower window 5 respectively. The guide chassis 2 may be coupled to the upper window 4, while the rotatable chassis 3 may be coupled to the lower window 5. In an upper portion of the inner space of the housing 1, the guide chassis 2 may be disposed, while, in a lower portion of the inner space of the housing 1, the rotatable chassis 3 may be disposed. The bottom of the upper window 4 may contact the top of the lower window 5 to realize the closing mode of the present rotatable and hung safety window assembly. In order to pull the upper window 4 toward the lower window 5, a handle 42 may be formed on the upper window 4 at the bottom end thereof. Thus, the user may pull the handle 42 and lower down the upper window 4 along the guide grooved lines 21 toward the lower window. In order to guide the upper window 4 to overlap the lower window 5 side by side horizontally, a horizontal grooved guide line may be formed in each of the opposite inner side wall of the guide chassis 2. Each horizontal grooved guide line may be coupled to each vertical grooved guide line in a right angle. Each horizontal grooved guide line may have a length larger than or equal to the thickness of the lower window 5. In this way, the user may pull the upper window 4 along the horizontal grooved guide lines and then lower down the upper window 4 along the vertical grooved guide lines, such that the upper window 4 may be arranged horizontally side by side with the lower window 5. In this way, both the lower window 5 and upper window 4 may be accommodated in the rotatable chassis 3. For the sake of a convenience, an esthetic aspect, and an easy operation, when the upper window 4 may be arranged horizontally side by side with the lower window 5, the lower window 5 may act as an outer window and the upper window 4 as an inner window.
In order to reach the state that the upper window 4 is lowered down to contact the bottom of the rotatable chassis 3 at the bottom end of the upper window 4, further guide grooved lines 31 may be vertically formed in opposite inner side walls of the rotatable chassis 3 at a predetermined length respectively to be coupled to the vertical guide grooved lines 21 defined in the guide chassis 2 respectively. In order to stop the movement of the upper window 4, stopper protrusions 32 may be formed on the opposite inner side walls of the rotatable chassis 3. In this way, the downward movement of the upper window 4 along the further guide grooved lines 31 may stop at the stopper protrusions 32 when the guide protrusions 41 contact the stopper protrusions 32 respectively.
Optionally, each of the guide chassis 2 and rotatable chassis 3 may have a chassis guard 22 partially extending in a parallel direction to a window plane of the upper window 4 and lower window 5. Thus, the chassis guard 22 may prevent the upper window 4 and lower window 5 from being removed away from the guide chassis 2 and rotatable chassis 3 due to the external force such as a heavy wind, etc.
The rotation of the rotatable chassis 3 via the hinge protrusion 34 may be limited in a rotation range in following manners. First, the hinge protrusion 34 may have a semi-circular shape and the first opposite hole 11 may have an arc shape with a length larger than a length of the semi-circular shape of the hinge protrusion 34. In this way, the rotation of the hinge protrusion 34 in the first opposite hole 11 may be limited in a rotation range. However, this approach may have shortcomings that the hinge protrusion 34 and first opposite holes 11 should have sufficient sizes and durability to withstand the repeated rotations thereof. Second, a stopper 12 may be formed to extend, for example, in a horizontal direction. The stopper 12 may extend from the housing 1 at the bottom thereof outwards. However, the present disclosure may not be limited thereto. The stopper 12 may be formed to extend in a predetermined angle to control the rotation range of the rotatable chassis 3.
Further, each rotatable link 33 may be hingedly coupled to the rotatable chassis 3 and housing 1 at each side of the rotatable chassis 3 and housing 1. Thus, when the stopper 12 is damaged not to control the rotation range of the rotatable chassis 3, the rotatable links 33 may maintain the rotation range of the rotatable chassis 3.
In addition, a screener 35 may be disposed to prevent the user' hand from being inserted into between the rotatable chassis 3 and housing 1. As the rotatable chassis 3 rotates, the screener 35 may be configured to vary in a size thereof. Thus, the screener 35 may be foldable in multiple times. This may have an advantage that the screener 35 may be kept in a small size when the rotatable chassis 3 is upright. To this end, the screener 35 is coupled, at one end thereof, to the housing 1 at a bottom thereof, and is coupled, at the other end thereof, to the rotatable chassis 3 at a bottom thereof. When the rotatable chassis 3 rotates, the screener 35 may be spread out based on the rotation angle of the rotatable chassis 3. In this way, the screener 35 may prevent the user' hand from being inserted into between the rotatable chassis 3 and housing 1.
Moreover, each of the rotatable chassis 3, stopper 12, upper window 4, lower window 5, and/or chassis guard 22 may have corners with an elastic coating made of an elastic material such as silicon. The elastic coating may act as the protection cover to prevent the user from being damaged from the corners.
An operation of the rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure will be as follows: initially, in a closing mode, the upper window 4 and lower window 5 may be vertically arranged side by side. Then, the user may pull the handle 42 of the upper window 4 inwardly and down along the guide grooved lines 21 of the guide chassis 2. The upper window 4 may be accommodated in the rotatable chassis 3 in the housing 1. Thus, the lower window 5 and upper window 4 may be arranged side by side horizontally. In other words, they may overlap horizontally. The upper window 5 may be secured via the stopper protrusions 32 at bottom ends of the further guide grooved lines 31. In this state, the user may push the upper window 4 outwardly to rotate the upper window 4 and lower window 5, and rotatable chassis 3 collectively toward the stopper 12. At the same time, the screener 35 may be spread out based on the rotation angle of the rotatable chassis 3 to prevent the user' hand from being inserted into between the rotatable chassis 3 and housing 1. In this way, the rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure may act as both the hung window and hinged window.
The rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure may have a locking mechanism to improve the safety thereof. The locking mechanism may have a locker bar 52 on a lower end of the upper window 4 on an inner face thereof, and multiple (in this example, two) locker links 51, each link having a lower end coupled to the lower window 5 and an upper end coupled to the locker bar 52.
The locker bar 52 may be made of a material capable of absorbing an external shock such as rubber, silicon, sponge, etc. The locker bar 52 may have substantially the same length as the horizontal width of the upper window 4. The locker bar 52 may have a thickness smaller than or equal to the thickness of the upper window 4 or lower window 5.
The locker link 51 may be hingedly moveable. To this end, the locker link 51 may have one end hingedly coupled to the lower window 5 and the other end hingedly coupled to the locker bar 52. The locker link 51 may operate in a vehicle-wiper manner. Although not shown, each locker link 51 may be outwardly tilted from the lower window 5 to the locker bar 52. This tiled configuration may allow the locker bar 52 to more reliably pressure the upper window 4 to improve a safety of the present window.
The locker bar 52 may have multiple elongate slots 53 at the locations where the locker links 51 are hingedly coupled to the locker bar 52. Thus, each locker link 51 may be moveable along each elongate slot 53. The locker bar 52 may be moveable via the movement of the locker link 51. The elongate slot 53 may act as a movement channel of the locker link 51. Further, the locker bar 52 may move in a vehicle-wiper manner via the hingedly movement of the locker link 51.
In operation, in a closing mode, when the upper window 4 and lower window 5 may be arranged side by side vertically, the locker bar 52 may be moved so as to block a boundary between the upper window 4 and lower window 5. Thus, the user' hand may be prevented from being inserted into between the lower window 5 and upper window 4. At the same time, the locker bar 52 may prevent the upper window 4 from moving inwardly and downwardly along the guide lines to open the present window.
In an open mode, the locker bar 52 may be moved to unblock the upper window 4, then, the upper window 4 may be pulled down to overlap the lower window 5. Thus, the overlap between the upper window and lower window may define the step portion because the upper window has a smaller vertical length than that of the lower window. The locker bar 52 may be moved to be located in the step portion. In this state, the locker link 51 may be oriented horizontally. Thus, the space between the upper window 4 and lower window 5 may be blocked by the locker bar 52. In this way, the user' hand may be prevented from being inserted into between the lower window 5 and upper window 4. When the upper window has the same vertical length as that of the lower window, the locker bar 52 may be located at a top of the lower window 5 and upper window 4 to prevent the user' hand from being inserted into between the lower window 5 and upper window 4. Further, the locker bar 52 may prevent the upper window 4 from being removed away from the rotatable chassis 3.
In order to allow the movement of the upper window 4 when the lower window 5, locker bar 52, and upper window 4 are collectively accommodated in the rotatable chassis 3, there may be a clearance or gap between the upper window 4 and lower window 5. In order to improve the movement of the upper window 4, the locker bar 52 may be made of an elastic material and/or may have rounded corners. When the locker bar 52 may be made of an elastic material, the locker bar 52 may be shrunk during the downward movement of the upper window 4, while, the locker bar 52 may be restored in a volume when the locker bar 52 may be located in a boundary between the upper window 4 and lower window 5, thereby to block the gap or clearance between the upper and lower windows. When the locker bar 52 has the rounded corners, the movement of the upper window 4 may be more facilitated.
In addition, the locker link 51 may be coupled to the lower window 5 via a height-adjustable shaft (not shown), In this way, the level of the locker link 51 may be adjusted freely. The locker bar 52 may have more flexible movements. Thus, the locker bar 52 may be reliably positioned to block the gap between the upper window 4 and lower window 5. Further, the locker bar 52 may have a shaft channel passing through to the slot 53 to allow the shaft to move through the shaft channel to be received into the slot 53.
The operation of the rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure may be as follows in more details: initially, the upper window 4 and lower window 5 may be arranged side by side vertically, which may be a closing mode. In this connection, the locker bar 52 hingedly coupled to the lower window 5 via the locker link 51 may be located at the highest position via an upright orientation of the locker link 51, such that the locker bar 52 may push outwards the upper window 4 and lock the movement of the upper window 4. In order to move the upper window 4 down, the locker bar 52 may be hingedly lowered down toward the lower window. In this connection, the locker link 51 may move along the elongate slot 53 defined in the locker bar 52, and the shaft (not shown) coupled to the locker link 51 may be received in the elongate slot 53. Thus, the locker bar 52 may be moved to the lower window 5. Subsequently, the user may pull the handle 42 on the upper window 4 to move inwardly and down the upper window 4. Thus, the upper window may be guided along the guide grooved lines 21 defined in the guide chassis 2. In this connection, since the locker bar 52 is made of the deformable material such as an elastic material, the movement of the upper window 4 may not be restricted. The upper window 4 may be located in the rotatable chassis 4 in an inner portion thereof. In this way, the lower window 5 and upper window 4 may be accommodated in the guide chassis 2 to overlap horizontally with each other. The upper window 4 may be secured by the stopper protrusion 32 formed at the bottom end of the further guide grooved line 31. In this state, the locker bar 52 may be positioned to a boundary between the lower window 5 and upper window 4 to bock the gap therebetween. Thus, the user' hand may be prevented from being inserted into between the lower window 5 and upper window 4.
The rotatable and hung safety window assembly in accordance with one embodiment of the present disclosure may have the cover 36 to prevent the upper window 4 from being separated from the rotatable chassis during the rotation of the rotatable chassis. The cover 36 may be coupled to the rotatable chassis 3 at each side thereof via each hinge. The cover 36 may have a liner shape or stepped shape. The stepped shape may correspond to the step portion defined by the upper window 4 and lower window 5 overlapping each other horizontally in case that the upper window and lower window have different vertical lengths as described above. Further, a fixing guard may be formed in the stepped shape at each side of the rotatable chassis to function like the chassis guard 22. Thus, the cover 36 may be hingedly rotated to be coupled to the top portions of the upper window 4 and lower window. In this state, the rotatable chassis 3 may rotate. Due to the cover 36, during the rotation of the rotatable chassis 3, the upper window 4 may be prevented from being separated from the rotatable chassis 3.
When the cover 36 is coupled to the rotatable chassis 3 via the hinge, it has a disadvantage that the rotatable chassis 3 should extend by the length of the cover 36. In order to remedy the disadvantage, a cover accommodation hole 38 may be formed in the rotatable chassis 3 to have a corresponding size and position to the cover 36. In this connection, the hinge may be disposed adjacent to the cover accommodation hole 38. Normally, the cover 36 may be received in the cover accommodation hole 38. When the upper window 4 is moved into the rotatable chassis 3, the cover 36 may be withdrawn from the cover accommodation hole 38 and may be coupled to the upper window 4 and lower window 5 on the top faces thereof. This may remove the need for changing the existing chassis size. Further, this may allow utilization of non-used portions in the existing chassis. This may allow the existing chassis to be adapted for the present rotatable and hung safety window assembly.
The above description is not to be taken in a limiting sense, but is made merely for the purpose of describing the general principles of exemplary embodiments, and many additional embodiments of this disclosure are possible. It is understood that no limitation of the scope of the disclosure is thereby intended. The scope of the disclosure should be determined with reference to the Claims. Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic that is described in connection with the embodiment is included in at least one embodiment of the present disclosure. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.
