Description

Technical Field

[0001] The present invention relates to a window-fastening safety guardrail device, and more particularly, to a window-fastening safety guardrail device which has a viewing function and can perform indoor ventilation and ventilation while ensuring durability against internal and external impacts and having safety. Background Art

[0002] Usually, steel partitions are installed outside the apartment balcony or balcony windows.

[0003] Such steel partitions not only look like iron bars, but also look unsightly.

[0004] Therefore, recently, in order to pursue the beauty of the building and retain the view from the inside of the living room to the outside, the partition is installed using plate-type tempered glass that cannot be ventilated and ventilated.

[0005] However, if plate-type tempered glass is used to form a partition, although the external view can be retained, it blocks the flow of air, thereby interfering with the ventilation of the air in the house.

[0006] Thus, Korean Patent No. 2024970 proposes a technology related to a partition using plate-type tempered glass.

[0007] However, Patent Document 1 fixes the glass partition to a fixed window frame to play a partition role, but the hot air in the room can only be discharged when the cold air outside flows in from the lower part of the window through convection. Although ventilation can be carried out through the open upper side, the outside air cannot flow in because of the glass partition, so there is a problem of reduced indoor ventilation and ventilation efficiency.

[0047] The above objects, features and other advantages of the present invention will become more apparent by describing in detail preferred embodiments of the present invention with reference to the accompanying drawings.

[0048] According to the present invention, the following effects are achieved: each corner of the guardrail frame is connected to an angle bracket, and blades made of transparent material are sequentially coupled to the opposite surfaces of the guardrail frame, so that the blades are located in front of the blade and blade isolation space in an interval state, and then the two ends are fixed to the frame rails of the fixed window and the horizontal sliding window opposite thereto, so that the ventilation and ventilation are good when the sliding window is opened; the blades are made of transparent material so as not to interfere with the external vision and can reduce the construction cost, and can be operated without using equipment or cranes; the lateral width and height of the part coupled to the frame rail are longer than the lateral width and height of the part fixed to the fixed window, so that the upper and lower and left and right widths look the same after being coupled to the frame rail, and a reinforcement part is installed on the part fixed to the fixed window, so that it can be firmly fixed. In addition, considering that the width of the window frame is different according to each construction site, the present invention cuts the extruded guardrail frame into lengths and then assembles it, so it is easy to deal with. In addition, the present invention has the following effects: the interval adjustment part is inserted between the blades in sequence, so that the opening and closing rate of the blades can be adjusted, and a track insertion groove is formed integrally on the guardrail frame and the corner bracket so that it can be inserted into the frame track of the horizontal sliding window, or an independent track coupling part with a track insertion groove is combined to effectively operate, and a blade protection part is provided at the contact part between the blade and the guardrail frame to prevent damage when the blade is glass.

[0049] Reference Figures 1 to 11 , a window fastening safety guardrail device 10 according to a first embodiment of the present invention includes a guardrail frame 100 , an angle bracket 200 and a blade 300 .

[0050] At this time, the window fastening safety guardrail device 10 according to the first embodiment of the present invention is as follows: Figure 1 The horizontal sliding window 1 is shown behind the sliding window 3 installed on one side or both sides of the fixed window 2 (in front of the insect-proof net), and ventilation and ventilation can be carried out through the gaps in the front and rear or left and right gaps or the upper and lower gaps of the blades 300 made of transparent material.

[0051] Here, the horizontal sliding window 1 has a fixed window 2 fixed to a frame rail 1 a and has a sliding window 3 that moves along the frame rail 1 a on one or both sides of the fixed window 2 .

[0052] like Figures 1 to 7 As shown, the guardrail frame 100 is connected into a four-corner frame structure so as to have a length corresponding to the length of the sliding window 3, and both sides are fixed between the fixed window 2 and the horizontal sliding window 1 opposite thereto.

[0053] At this time, the guardrail frame 100 includes a first frame 110, a second frame 120, a third frame 130, a fourth frame 140 and a reinforcement 150, and the first to fourth frames 110, 120, 130, 140 are formed by extrusion molding, and the reinforcement 150 is formed by bending a metal plate.

[0054] In addition, the height H1 of the second frame 120 and the lateral width W1 of the third frame 130 are greater than the height H2 of the first frame 110 and the lateral width W2 of the fourth frame 140. This is because the first track coupling portion 128 and the second track coupling portion 134 of the second frame 120 and the third frame 130 are respectively coupled to the lower frame rail 1a and the side frame rail 1a of the horizontal sliding window 1, thereby ensuring that the coupled portion ( Figure 6 ).

[0055] Therefore, the height of the second frame 120 and the lateral width of the third frame 130 are higher and longer than the height of the first frame 110 and the lateral width of the fourth frame 140, but when inserted into the lower frame rail 1a and the one side frame rail 1a of the horizontal sliding window 1 and viewed from the front, the heights of the first frame 110 and the second frame 120 appear the same, and the lateral widths of the third frame 130 and the fourth frame 140 appear the same.

[0056] Finally, the second frame 120 is coupled to the lower frame rail 1a of the horizontal sliding window 1 with a height obtained by subtracting the height H1 of the second frame 120 from the height H2 of the first frame 110, and the third frame 130 is coupled to the side frame rail 1a of the horizontal sliding window 1 with a width obtained by subtracting the lateral width W1 of the third frame 130 from the lateral width W2 of the fourth frame 140.

[0057] The first frame 110 is laterally located on the upper side of the guardrail frame 100, and a first coupling portion 112 is formed at the inner center so that the 1-1 coupling protrusion 212 of the first bracket portion 210 and the 3-1 coupling protrusion 232 of the third bracket portion 230 are fastened on both sides with the longitudinal first partition wall 111 as the starting point, and a first fastening hole 114 fastened to the lower portion of the first partition wall 111 is formed in the length direction so that the first bracket portion 210 and the third bracket portion 230 can be fixed with bolts, and a first protective member insertion groove 116 is formed at the lower portion so that the protective member coupled to one end of the blade 300 can be inserted.

[0058] At this time, the first frame 110 has an advantage that its upper surface is formed in a round shape so as to be smooth.

[0059] Also, if Fig. 9 As shown, the blade protection portion 160 is inserted into the first prevention member insertion groove 116 with a length corresponding to the first prevention member insertion groove 116 .

[0060] When the blade 300 is made of glass, the blade protection portion 160 is configured to prevent damage caused by collision with the first frame 110 made of metal. It includes a main body 162 with a ∩-shaped cross-section that is inserted into the first protective member insertion groove 116, an insertion groove 164 that is formed with an opening on the bottom side of the main body 162 so that the upper end of the blade 300 is inserted, and a wing portion 166 that is formed on the inlet side of the insertion groove 164 so as to contact the two side surfaces of the blade 300.

[0061] In addition, the blade protection part 160 is formed by double extrusion, preferably, its main body 162 is formed by soft and hard materials (such as PVC as an example), and the wing part 166 is formed by super soft materials (such as PVC as an example). In this way, the blade protection part 160 is firmly combined with the first protection member insertion groove 116 through the hard main body 162, and is tightly attached to the two sides of the blade 300 without damage through the wing part 166 of the soft material, thereby eliminating gaps and playing a sealing role.

[0062] The second frame 120 is arranged at the lower side of the guardrail frame 100 in the transverse direction, and a second coupling portion 122 is formed inside so as to have a 2-1 partition wall 121a formed in the transverse direction and a 2-2 partition wall 121b formed in the center of the 2-1 partition wall 121a in the longitudinal direction, and the 2-1 coupling protrusion 222 of the second bracket part 220 and the 4-1 coupling protrusion 242 of the fourth bracket part 240 are fastened on both sides with the 2-2 partition wall 121b as a starting point, a second guard member insertion groove 124 is formed for inserting a guard member coupled to the other end of the blade 300, and a second fastening hole 126 fastened to the center of the 2-2 partition wall 121b is formed in the length direction so as to fix the second bracket part 220 and the fourth bracket part 240 by bolts, and a first track coupling portion 128 is formed at the lower part so as to be coupled to the lower side frame track 1a of the horizontal sliding window 1.

[0063] In addition, the first rail coupling portion 128 is symmetrically bent in a rounded manner on both parallel sides of the second frame 120 and then extends in a 180° direction, thereby having elastic force when closely attached to the frame rail 1 a .

[0064] In addition, if Fig. 9 As shown, the blade protecting portion 160 is inserted into the second preventing member insertion groove 124 with a length corresponding to the second preventing member insertion groove 124 .

[0065] At this time, the blade protection part 160 is symmetrical with the blade protection part 160 installed in the first prevention member insertion groove 116 with the horizontal axis as a starting point and has the same structure and function, so a detailed description will be omitted.

[0066] The third frame 130 is longitudinally arranged on one side of the first frame 110 and one side of the second frame 120, and forms a third coupling portion 132 inside, so that the third partition wall 131 formed along the transverse direction is used as a starting point, and the third coupling portion 132 is formed at the inner end to fasten the 1st-2 coupling protrusion 214 of the first bracket part 210 and the 2nd-2 coupling protrusion 242 of the second bracket part 220, and a second track coupling portion is formed at the outer end so as to be coupled to the frame track 1a on one side of the horizontal sliding window 1.

[0067] Also, the second rail coupling portion 134 is symmetrically bent in a rounded manner on two parallel sides of the third frame 130 and then extends in a 180° direction, so as to have elastic force when closely attached to one side frame rail 1a.

[0068] In addition, the third frame 130 is located in a direction of the frame rail 1 a on one side of the horizontal sliding window 1 .

[0069] The fourth frame 140 is disposed longitudinally at the other side of the first frame 110 and the other side of the second frame 120, and a fourth coupling portion 142 is formed inside to fasten the 3-2 coupling protrusion 234 of the third bracket portion 230 and the 4-2 coupling protrusion 244 of the fourth bracket portion 240, and a step 144 is formed on both sides. At this time, the step 144 is formed to correspond to the thickness of the second bent end 154 of the reinforcing portion 150, so as to prevent protrusion when the reinforcing portion 150 is fixed.

[0070] In addition, the reason why the step difference 144 is formed on both sides of the fourth frame 140 is that the position of the second bent end 154 of the reinforcement portion 150 is different depending on whether the sliding window 3 is a right window or a left window, so the second bent end 154 can be installed regardless of the direction.

[0071] The reinforcing portion 150 is located between the fixed window 2 and the other side of the guardrail frame 100 and the corner bracket 200 fixed to the fixed window 2, and plays a reinforcing role in preventing the other side of the guardrail frame 100 and the corner bracket 200 from moving backward (toward the outdoors). The reinforcing portion 150 includes a first bent end 152 and a second bent end 154.

[0072] That is, the second frame 120 and the second bracket portion 220 and the fourth bracket portion 240 fixed on the left and right of the second frame 120 and the third frame 130 and the first bracket portion 210 and the second bracket portion 220 fixed on the upper and lower parts of the third frame 130 are fixed to one side and the lower frame rail 1a by the first rail joint portion 128 and the second rail joint portion 134 and are firmly fixed. Different from this, when the fourth frame 140 and the third bracket portion 230 and the fourth bracket portion 240 fixed on the upper and lower parts of the fourth frame 140 are fixed to the fixed window 2 by bolts, their firm fixation is insufficient, and therefore it is necessary to install the reinforcement portion 150.

[0073] To this end, a plurality of fastening holes are formed so that the first bent end 152 is fixed to the fixed window 2 by bolts in a state where it is tightly attached to the same surface of the third bracket portion 230, the fourth bracket portion 240 and the fourth frame 140, and the second bent end 154 is tightly attached to the side surface (outdoor direction) of the third bracket portion 230, the fourth bracket portion 240 and the fourth frame 140.

[0074] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, the corner bracket 200 respectively connects the connection parts of the first frame 110 and the third frame 130, the connection parts of the second frame 120 and the third frame 130, the connection parts of the first frame 110 and the fourth frame 140, and the connection parts of the second frame 120 and the fourth frame 140, and includes a first bracket part 210, a second bracket part 220, a third bracket part 230 and a fourth bracket part 240.

[0075] The front side of the first bracket portion 210 is formed in a ┐ shape, and a 1-1 coupling protrusion 212 is arranged in the horizontal direction to be coupled to the first coupling portion 112 of the first frame 110, and a 1-2 coupling protrusion 214 is arranged in the longitudinal direction to be coupled to the third coupling portion 132 of the third frame 130, and the upper part of the 1-2 coupling protrusion 214 as the outer side surface forms a first track insertion groove 216, so as to be coupled to the side frame track 1a of the horizontal sliding window 1.

[0076] In addition, a third fastening hole 218 is formed in the first rail insertion groove 216 so that the first bracket portion 210 is positioned in a state of being concentric with the first fastening hole 114 of the first frame 110 and fastened by bolts, and fourth fastening holes 219 are formed on both sides of the third fastening hole 218 so as to be fixed by bolts to the horizontal sliding window 1 formed with a one side frame rail 1a.

[0077] At this time, when the fourth fastening holes 219 are located on both sides of the first bracket portion 210 and are fixed to the horizontal sliding window 1 formed with the frame rail 1a on one side by bolts, interference with the blade 300 coupled to the center can be avoided. Also, for the same reason as the fourth fastening hole 219, the sixth fastening hole 229, the eighth fastening hole 238, and the tenth fastening hole 248 are also formed on both sides of the second bracket portion 220 to the fourth bracket portion 240.

[0078] The front side of the second bracket portion 220 is formed in a ┘ shape, and a 2-1 coupling protrusion 222 is arranged in the horizontal direction to be coupled to the second coupling portion 122 of the second frame 120, and a 2-2 coupling protrusion 224 is arranged in the longitudinal direction to be coupled to the third coupling portion 132 of the third frame 130. The lower second track insertion groove 226 of the 2-2 coupling protrusion 224 as the outer side extends to the bottom, thereby simultaneously coupling to one side of the horizontal sliding window 1 and the lower frame track 1a.

[0079] In addition, a fifth fastening hole 228 is formed in the second rail insertion groove 226, and the second bracket portion 220 is fastened using bolts in a state concentric with the second fastening hole 126 of the second frame 120, and sixth fastening holes 229 are formed on both sides of the fifth fastening hole 228 so as to be fixed to the horizontal sliding window 1 formed with a one side frame rail 1a by bolts.

[0080] The front side of the third bracket portion 230 is formed in a ┌ shape, and a 3-1 coupling protrusion 232 is arranged in the transverse direction to be coupled to the first coupling portion 112 of the first frame 110, and a 3-2 coupling protrusion 234 is arranged in the longitudinal direction to be coupled to the fourth coupling portion 142 of the fourth frame 140, and a first coupling step difference 2340 is formed with the outer side surface and the two side surfaces adjacent thereto, so that the second bent end 154 of the reinforcing portion 150 is tightly attached to the desired position, so that the reinforcing portion 150 does not protrude compared to the outer side surface of the third bracket portion 230.

[0081] At this time, when the window fastening safety guardrail device 10 is fixed to the sliding window 3 on the left and to the sliding window 3 on the right, the direction of the reinforcement part 150 must be changed. Therefore, considering this point, the first coupling step difference 2340 is respectively formed on the outer side surface of the third bracket part 230 and the two side surfaces adjacent thereto.

[0082] In addition, a seventh fastening hole 236 is formed at the upper end of the center portion so that the third bracket portion 230 is positioned concentric with the first fastening hole 114 of the first frame 110 and fastened by bolts, and eighth fastening holes 238 are formed on both sides of the lower portion of the seventh fastening hole 236 so as to be fixed to the fixed window 2 by bolts.

[0083] The front side of the fourth bracket portion 240 is formed in an L shape, and a 4-1 coupling protrusion 242 is arranged in the horizontal direction to be coupled to the second coupling portion 122 of the second frame 120, and a 4-2 coupling protrusion 244 is arranged in the longitudinal direction to be coupled to the fourth coupling portion 142 of the fourth frame 140, and a second coupling step difference 2440 is formed with the outer side surface and the two side surfaces adjacent thereto, so that the second bent end 154 of the reinforcing portion 150 is tightly attached to the desired position, thereby preventing the reinforcing portion 150 from protruding more than the outer side surface of the fourth bracket portion 240.

[0084] The fourth bracket portion 240 forms a third rail insertion groove 245 at a lower portion so as to be coupled to the lower frame rail 1 a of the horizontal sliding window 1 .

[0085] At this time, when the window fastening safety guardrail device 10 is fixed to the sliding window 3 on the left and to the sliding window 3 on the right, the direction of the reinforcement part 150 must be changed. Therefore, considering this, the second coupling step difference 2440 is respectively formed on the outer side surface of the fourth bracket part 240 and the two side surfaces adjacent thereto.

[0086] In addition, in the end of the third rail insertion groove 245, a ninth fastening hole 246 is formed in a groove extending in the vertical direction, so that the fourth bracket part 240 is fastened by bolts in a concentric state with the second fastening hole 126 of the second frame 120, and tenth fastening holes 248 are formed on the upper parts of both sides of the ninth fastening hole 246 so as to be fixed to the fixed window 2 by bolts.

[0087] like Figures 1 to 3 , Figure 6 and Figure 7 As shown, in order to protect the blade 300, both ends are inserted into the first and second protection member insertion grooves 116 and 124 of the first and second frames 110 and 120 in a state where the blade protection part 160 is combined, and a transparent plate or the like is suitable for this.

[0088] At this time, the blades 300 are shown to be spaced apart in the longitudinal direction in the first and second guard insertion grooves 116 and 124, but are not limited thereto and may be spaced apart in the transverse direction or in various shapes such as double rows or zigzags in addition to a single row.

[0089] The blade 300 is manufactured by heat treatment in a state where an adhesive film (not shown) is disposed between two tempered transparent plates. At this time, the blade 300 may increase or decrease its thickness.

[0090] Meanwhile, the blade 300 is not only made of tempered glass, but can also be made of synthetic resin including acrylic acid or polycarbonate (PC), etc., but is not limited thereto, and any transparent material can be applied.

[0091] In addition, the blades 300 and the interval adjusting portion 170 are sequentially inserted into the first protection member insertion groove 116 and the second protection member insertion groove 124, and the interval of the blades 300 can be adjusted by the interval adjusting portion 170. At this time, preferably, the interval adjusting portion 170 has a cross-section having a shape corresponding to the cross-section of the insertion groove 164 formed in the blade protection portion 160.

[0092] Specifically, the interval adjustment unit 170 can adjust the intervals between the blades 300 through different sizes (lengths), thereby adjusting the closing degree and opening degree of the blades 300, thereby adjusting the opening and closing rate of the blades 300.

[0093] Thus, the assembly and installation process of the window fastening type safety guardrail device 10 according to the first embodiment of the present invention will be described as follows.

[0094] First, the 3-2 coupling protrusion 234 of the third bracket portion 230 and the 4-2 coupling protrusion 244 of the fourth bracket portion 240 are coupled to the upper and lower portions of the fourth coupling portion 142 of the fourth frame 140 , respectively.

[0095] Next, when the first coupling portion 112 of the first frame 110 is coupled to the 3-1 coupling protrusion 232 of the third bracket portion 230, the seventh fastening hole 236 of the third bracket portion 230 is formed concentric with the first fastening hole 114 of the first frame 110 by bolt fastening, thereby fixing the first frame 110 to the third bracket portion 230.

[0096] Next, the second coupling portion 122 of the second frame 120 is coupled to the 4-1 coupling protrusion 242 of the fourth bracket portion 240, and the ninth fastening hole 246 of the fourth bracket portion 240, which is concentric with the second fastening hole 126 of the second frame 120, is fastened by bolts, thereby fixing the second frame 120 to the fourth bracket portion 240 ( shape).

[0097] Next, the blade protection part 160 is inserted into the first protection member insertion groove 116 of the first frame 110 and the second protection member insertion groove 124 of the second frame 120, respectively, and then the blade 300 and the interval adjustment part 170 are sequentially combined between the insertion grooves 164 of the blade protection part 160 facing each other up and down, so as to adjust the interval between the blade 300 and the blade 300. In this way, the blade protection part 160 prevents the blade 300 from directly contacting the first protection member insertion groove 116 and the second protection member insertion groove 124, thereby preventing damage when the blade is made of glass.

[0098] Next, the 1-2 coupling protrusion 214 of the first bracket portion 210 and the 2-2 coupling protrusion 214 of the second bracket portion 220 are coupled to the upper and lower portions of the third coupling portion 132 of the third frame 130 (I-shape), respectively.

[0099] Next, when the first coupling portion 112 of the first frame 110 is coupled to the 1-1 coupling protrusion 212 of the first bracket portion 210, the first fastening hole 114 of the first bracket portion 210 is fastened by bolts to form a concentric first fastening hole 114 of the first frame 110, thereby fixing the first bracket portion 210 to the first frame 110.

[0100] Next, the second coupling portion 122 of the second frame 120 is coupled to the 2-1 coupling protrusion 222 of the second bracket portion 220, and the fifth fastening hole 228 of the second bracket portion 220 is formed concentric with the second fastening hole 126 of the second frame 120 by bolts, thereby fixing the second bracket portion 220 to the second frame 120 ( shape).

[0101] Furthermore, when installing the window fastening safety guardrail device 10, the first track insertion groove 216 of the first bracket part 210, the first track coupling part 128 of the second frame 120 and the side of the second track insertion groove 226 of the second bracket part 220 are coupled to the side frame rail 1a of the horizontal sliding window 1, and the bottom of the second track insertion groove 226 of the second bracket part 220, the second track coupling part 134 of the third frame 130 and the third track insertion groove 245 of the fourth bracket part 240 are coupled to the lower side frame rail 1a of the horizontal sliding window 1, and then the first bracket part 210 and the second bracket part 220 are fixed to the side frame rail 1a of the horizontal sliding window 1 by using bolts and through the fourth fastening hole 219 and the sixth fastening hole 229.

[0102] Next, when the outer side surfaces of the third bracket portion 230 and the fourth bracket portion 240 connected to the upper and lower sides of the fourth frame 140 are aligned with the fixed window 2, the third bracket portion 230 and the fourth bracket portion 240 are fixed to the fixed window 2 by bolts through the eighth fastening hole 238 and the tenth fastening hole 248.

[0103] At the same time, before fixing the third bracket portion 230 and the fourth bracket portion 240 to the fixed window 2 with bolts, the reinforcement portion 150 is fixed to the fixed window 2 with bolts to prevent the third bracket portion 230 and the fourth bracket portion 240 connected to the upper and lower sides of the fourth frame 140 fixed to the fixed window 2 from detaching in the outward direction.

[0104] That is, when the reinforcement part 150 is first fixed to the fixed window 2, the third bracket part 230 and the fourth bracket part 240 connected to the upper and lower sides of the fourth frame 140 are tightly attached to the first bent end 152 of the reinforcement part 150, and the second bent end 154 is tightly attached to the side (outdoor direction) of the third bracket part 230 and the fourth bracket part 240 and the fourth frame 140, and then the third bracket part 230 and the fourth bracket part 240 are fixed to the fixed window 2 by bolts through the eighth fastening hole 238 and the tenth fastening hole 248.

[0105] Reference Fig.12 , a window fastening safety guardrail device 10 ′ according to a second embodiment of the present invention includes a guardrail frame 100 ′, an angle bracket 200 ′ and a blade 300 ′.

[0106] At this time, as in the first embodiment, the guardrail frame 100′ includes a first frame 110′, a second frame 120′, a third frame 130′, a fourth frame 140 and a reinforcement portion (not shown), and as in the first embodiment, the corner bracket 200′ includes a first bracket portion 210′, a second bracket portion 220′, a third bracket portion 230′ and a fourth bracket portion 240′.

[0107] In addition, the window fastening safety guardrail device 10′ according to the second embodiment of the present invention is different from the first embodiment in which the second rail coupling portion 134 is formed on the outer side of the third frame 130, the second rail insertion groove 226 and the third rail insertion groove 245 and the first rail coupling portion 128 are integrally formed on the bottom side of the second bracket portion 220 and the bottom side of the fourth bracket portion 240 and the bottom side of the second frame 120 located on the same horizontal plane, thereby being combined on one side of the horizontal sliding window 1 and the lower frame rail 1a. The difference is that the second rail insertion groove and the third rail insertion groove are formed on the bottom side of the second bracket portion 220′ and the bottom side of the fourth bracket portion 240′, but the outer side of the third frame 130′ and the bottom side of the second frame 120′ have a surface without a groove, and are combined by bolts or the like in a state in which a rail coupling portion 136′ with a rail insertion groove 136a′ is separately manufactured on the outer side of the third frame 130′, and the rest is the same.

[0108] Here, the rail coupling portion 136 ′ is shown as being disposed at a portion of the outer side of the third frame 130 ′, but is not limited thereto and may correspond to the entire length of the third frame 130 ′ or be disposed at various positions of the third frame 130 ′ in a divided state.

[0109] In addition, the rail coupling portion 136' is shown as being provided on the third frame 130', but may also be provided on the second frame 120', and the second rail insertion groove and the third rail insertion groove may also be provided without forming the bottom sides of the second bracket portion 220' and the fourth bracket portion 240'.

[0110] The configurations included in the various embodiments described above may also be implemented through other possible various modified combinations not illustrated above, as long as they are not combinations that are obviously mutually exclusive.
