Description

Technical Field

[0001] This invention relates to the field of door and window transportation accessories, specifically to a protective device for door and window transportation. Background Technology

[0002] In recent years, system windows and doors have experienced explosive growth. This is because consumers have increasingly higher requirements for the functionality of windows and doors in terms of quality, stability, energy efficiency, mechanical strength, sound insulation, and other aspects. Traditional aluminum alloy windows and doors are gradually failing to meet consumers' diverse needs for window and door performance.

[0003] System windows are typically transported and installed as a whole frame because they use pins and glued corner joints, making on-site assembly impossible. Furthermore, the strength and sealing of the corner joints in system windows are crucial, determining the overall strength and waterproofing of the window assembly. Ordinary windows, on the other hand, are assembled from different custom-ordered components. Due to on-site construction limitations, ordinary aluminum alloy windows generally don't treat this area properly, or only apply a token amount of sealant to the joints, making it difficult to guarantee the overall stability of the window.

[0004] Obviously, transporting system windows in their entirety is more difficult than transporting ordinary doors and windows. Generally, during transportation, to prevent metal doors and windows from colliding, they are wrapped with pearl cotton, or sometimes with corrugated cardboard, using a wrapping structure to form a package. This consumes a lot of materials and none of them can be recycled. At the same time, with friction during transportation, the packaging materials will wear and tear at corresponding locations, affecting the internal protection. Some also use foam, bases, or other structures for support and fixation, but foam structures are custom-made and cannot be recycled. Some even use wooden boxes, which are troublesome to disassemble and assemble, and increase transportation costs. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device for transporting doors and windows that is reusable and facilitates the loading and unloading of the entire frame, thereby solving the problem of inconvenience in transporting the entire frame of doors and windows.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a protective device for transporting doors and windows, comprising a vertical frame fixed to a transport vehicle, and protective frame assemblies sequentially arranged along one side of the vertical frame in the transverse direction, wherein,

[0007] The bottom of the vertical frame is horizontally arranged with a fixed rod and a movable rod from bottom to top, and the movable rod can be driven to slide vertically along the vertical frame. The vertical frame also includes a front locking component that corresponds to the protective frame component.

[0008] The protective frame assembly includes a pair of parallel telescopic frame supports, with a space between the frame supports for storing doors and windows; the frame supports include several sets of support units that are hinged in an X-shape by a pair of support rods, and the several sets of support units are pivotally connected and form a rhomboid structure at the connection point; the front end of the frame support is hinged to a fixed rod and a movable rod respectively through the support rod of its foremost support unit; the frame support is hinged to a rear locking assembly through the support rod at the bottom of its rearmost support unit.

[0009] The front locking assembly includes a pair of front locking brackets that can slide along the fixed rod and the movable rod. The front locking brackets are respectively disposed on both sides of the protective frame assembly, and the front locking brackets bring the pair of frame brackets closer to each other by squeezing the support rod. The rear locking assembly includes a pair of rear locking brackets, and the rear locking brackets bring the pair of frame brackets closer to each other by squeezing the support rod.

[0010] The front locking assembly also includes a pair of front side locking plates fixedly connected to the front locking bracket. The pair of front side locking plates are slidably connected to a front active plate corresponding to the accommodating space via an inclined plate. The rear locking assembly includes a pair of rear side locking plates fixedly connected to the rear locking bracket. The pair of rear side locking plates are slidably connected to a rear active plate corresponding to the accommodating space via an inclined plate. When the front active plate and the rear active plate are squeezed from the accommodating space, the front side locking plates and the rear side locking plates move closer to each other.

[0011] The rear-end locking plate is slidably connected to a locking buckle, and the frame bracket is connected to a locking pin that cooperates with the locking buckle via a support rod at the top of its rearmost bracket unit.

[0012] Preferably, the movable rod and the fixed rod are provided with limiting protrusions for limiting the front locking bracket according to the width of the accommodating space.

[0013] Preferably, the vertical frame includes a pair of vertical columns, and the bottom of the vertical columns is provided with a base. The vertical columns are provided with sliding blocks that slide along them. The two ends of the fixed rod are respectively fixed to the bases of the pair of vertical columns, and the two ends of the movable rod are respectively fixed to the sliding blocks of the pair of vertical columns.

[0014] Preferably, the slide block is driven by a lead screw mechanism to slide vertically along the vertical column, and the vertical frame is also provided with a motor for driving the lead screw mechanism.

[0015] Preferably, it also includes a rear stabilizing frame, which includes a support body vertically fixed on the transport vehicle and a horizontal stabilizing frame fixed on the support body. The horizontal stabilizing frame has a stabilizing rod fixed to each pair of frame supports, and the rear active plate has a corresponding fitting groove for the stabilizing rod.

[0016] Preferably, the fixed rod and the movable rod are fitted with a return spring that abuts against the inside of the support rod at the accommodating space of each pair of frame supports.

[0017] Preferably, the support unit in the protective frame assembly has a rolling structure pivotally connected at the connection point of its support rod facing the bottom. The rolling structure includes rolling wheels disposed on both sides of the protective frame assembly for contacting the transport vehicle, and also includes rollers disposed between the frame supports for supporting doors and windows.

[0018] Preferably, the rear active plate is fixedly connected to a clamping part for clamping the door and window frame on the side facing the accommodating space, and the clamping part includes a clamping opening and elastic clamping wedges on both sides of the clamping opening.

[0019] Preferably, a vertical retainer is provided between adjacent support units, and the retainer has a flexible pad on the side facing the accommodating space, and the retainer has a vertical clearance groove.

[0020] The beneficial effects of this invention compared to the prior art are:

[0021] First, this invention makes it very convenient to load doors and windows into the transport vehicle. The system windows to be transported are fed in sequence along the frame brackets, and then the locking port of the rear locking component is engaged with the locking pin. Then, the motor is started to automatically tighten the doors and windows, so that the side and bottom frames of the doors and windows are covered, thereby fixing multiple system windows at the same time and realizing rapid loading of system windows during transportation.

[0022] Secondly, when unloading after transportation, this invention only requires releasing the rear locking component and starting the motor to extend the frame support, which allows the loaded system window to be moved to the rear of the frame support, facilitating rapid unloading.

[0023] Furthermore, while providing excellent protection during transportation, this invention also avoids the use of consumables in conventional transportation. For example, conventional transportation usually requires the repeated wrapping of packaging materials such as corrugated paper, foam, pearl cotton, and film around the system window to create a buffer and protective effect, and template supports are also needed for support. Therefore, the cost of consumables during transportation is high and they are not easy to reuse. In contrast, this invention uses less consumables, reduces costs, does not require other support devices, and can be reused repeatedly, thus achieving both green and environmentally friendly transportation and reducing transportation costs.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0041] Reference Figures 1 to 8 A protective device for transporting doors and windows includes a vertical frame 100 fixed to a transport vehicle, and protective frame assemblies 200 sequentially arranged along one side of the vertical frame in a transverse direction. The vertical frame 100 can be fixed to the transport vehicle in various ways, such as a truck bed, train car, or container, for example, by bolting it to the floor of the truck bed. Figure 1 As shown, the lateral direction refers to the width of the carriage, and the vertical / vertical direction refers to the direction pointing vertically downwards towards the ground.

[0042] like Figures 2 to 4 As shown, the bottom of the vertical frame 100 is horizontally arranged with a fixed rod 110 and a movable rod 120 from bottom to top, and the movable rod 120 can be driven to slide vertically along the vertical frame 100. The vertical frame 100 also includes a front locking component 300 that corresponds to the protective frame component 200.

[0043] The protective frame assembly 200 includes a pair of parallel telescopic frame supports 210, with a space 600 between the frame supports 210 for storing doors and windows 400; the frame supports 210 include several sets of support units 220 that are hinged in an X-shape by a pair of support rods 221, and the several sets of support units 220 are pivotally connected and form a rhomboid structure at the connection point; the front end of the frame support 210 is hinged to the fixed rod 110 and the movable rod 120 respectively through the support rod 221 of its foremost support unit 220; the frame support 210 is hinged to the rear locking assembly 500 through the support rod 221 at the bottom of its rearmost support unit 220.

[0044] The front locking assembly 300 includes a pair of front locking brackets 310 that can slide along the fixed rod 110 and the movable rod 120. The front locking brackets 310 are respectively disposed on both sides of the protective frame assembly 200, and the front locking brackets 310 bring the pair of frame brackets 210 closer to each other by pressing the support rod 221. The rear locking assembly 500 includes a pair of rear locking brackets 510, and the rear locking brackets 510 bring the pair of frame brackets 210 closer to each other by pressing the support rod 221.

[0045] In this invention, the paired frame supports 210 form a accommodating space 600 for placing doors and windows 400. Taking a truck bed as an example, the vertical frame 100 is horizontally fixed inside the truck bed, and the doors and windows to be loaded are pushed into the accommodating space between the frame supports 210 in sequence, thus completing the initial loading.

[0046] The front locking assembly 300 also includes a pair of front side locking plates 320 fixedly connected to the front locking bracket 310. The pair of front side locking plates 320 are slidably connected to a front active plate 330 corresponding to the accommodating space through an inclined plate. The rear locking assembly 500 includes a pair of rear side locking plates 520 fixedly connected to the rear locking bracket 510. The pair of rear side locking plates 520 are slidably connected to a rear active plate 530 corresponding to the accommodating space 600 through an inclined plate. When the front active plate 330 and the rear active plate 530 are squeezed from the accommodating space 600, the front side locking plates 320 and the rear side locking plates 520 move closer to each other.

[0047] like Figure 4 and Figure 5 As shown, the rear-end locking plate 520 is slidably connected to a locking buckle 521, and the frame bracket 210 is connected to a locking pin 522 that cooperates with the locking buckle 521 via a support rod 221 above its rearmost support unit 220. The locking buckle 521 can be slidably connected to the rear-end locking plate 520 through a sliding groove structure.

[0048] After initial loading, the rear locking assembly 500 is connected to the frame bracket 210 through the cooperation of the locking buckle 521 and the locking pin 522. Then, the movable rod 120 is slid away from the fixed rod 110, and the frame bracket 210 composed of the bracket units 220 shortens along the length of the carriage until both the front and rear ends of the frame bracket 210 abut against the sides of the door / window 400. Since in this invention, the front locking plate 320 and the front active plate 330, and the rear locking plate 520 and the rear active plate 530 are all inclined mating plates, the contact with the door / window 400 causes the front active plate 330 and the rear active plate 530 to slide in opposite directions under pressure, while the front locking plate 320 and the rear locking plate 520 move towards the door / window 400 and finally adhere to both sides of the door / window 400, forming a... Figure 5 As shown, when the door and window 400 is completely fixed and does not wobble relative to the frame bracket 210, the installation of the door and window 400 is complete.

[0049] Of course, in some embodiments, special protection is still required for the doors and windows 400 during loading, such as installing corner protectors on their edges, covering the upper part of the doors and windows 400 with tarpaulins on the upper part of the truck bed, and embedding foam pads in the top gaps between adjacent doors and windows 400, etc. Therefore, it should be understood that the main function of the present invention is to provide primary and overall protection for the transportation of doors and windows 400.

[0050] Reference Figure 3 As shown, in order to avoid improper sliding of the protective frame assembly 200 relative to the fixed rod 110 and the movable rod 120, the movable rod 120 and the fixed rod 110 are evenly provided with limiting protrusions 130 for limiting the front locking bracket 310 according to the width of the accommodating space 600, so that the protective frame assembly 200 only slides between adjacent limiting protrusions 130.

[0051] Specifically, such as Figure 7 As shown, in some embodiments, the vertical frame 100 includes a pair of vertical columns 140, and the bottom of the vertical columns 140 is provided with a base 141. The vertical columns 140 are provided with a sliding seat 142 that slides along them. The two ends of the fixed rod 110 are respectively fixed to the base 141 of the pair of vertical columns 140, and the two ends of the movable rod 120 are respectively fixed to the sliding seat 142 of the pair of vertical columns 140. Preferably, the movable rod 120 and the fixed rod 110 should be made of high-strength material to avoid deformation due to the inertial impact of the goods (doors and windows 400) during transportation. Alternatively, a flat rod body can be used to improve its resistance to horizontal impact.

[0052] As a preferred driving method, the slide block 142 can be driven by the lead screw mechanism 150 to slide vertically along the vertical column 140, and the vertical frame 100 is also provided with a motor 160 for driving the lead screw mechanism 150. The control switch of the motor can be set at the rear of the carriage. After the initial loading, the staff can start the motor 160 to make the movable rod 120 slide away from the fixed rod 110.

[0053] Reference Figure 2 and Figure 8 As shown, in order to further ensure the stability of the door and window 400 during transportation, the present invention also includes a rear stabilizing frame 700. The rear stabilizing frame 700 includes a support body 710 vertically fixed on the transport vehicle and a horizontal stabilizing frame 720 fixed on the support body 710. The horizontal stabilizing frame 720 is fixed with a stabilizing rod 721 for each pair of frame supports 210. The rear active plate 530 is provided with a corresponding fitting groove 531 for the stabilizing rod 721, so that the rear stabilizing frame 700 can prevent the rear end of the protective frame assembly 200 from swinging.

[0054] like Figure 3 As shown, in order to facilitate the horizontal reset of the frame bracket 210, the fixed rod 110 and the movable rod 120 are fitted with a reset spring 170 that abuts against the inner side of the support rod 221 at the accommodating space 600 of each pair of frame brackets 210. After transportation, a pair of frame brackets 210 are automatically reset by the reset spring 170, which not only helps to avoid scratches when the door and window 400 is removed from the protective frame assembly 200, but also facilitates the next loading work.

[0055] At the same time, such as Figure 4 As shown, in order to make the retraction and extension of the protective frame assembly 200 in the length direction of the carriage smoother, the support unit 220 of the protective frame assembly 200 has a rolling structure pivotally connected at the connection of its support rod 221 towards the bottom. The rolling structure includes rolling wheels 230 disposed on both sides of the protective frame assembly 200 for contacting the transport vehicle, and also includes rollers 240 disposed between the frame supports 210 for supporting the doors and windows 400. It is worth noting that the rollers 240 in the rolling structure can not only prevent the doors and windows 400 from scratching the bottom frame of the doors and windows 400 when they slide into / out of the accommodating space 600, but also play a supporting role during transportation, thereby improving the overall stability of the protective frame assembly 200.

[0056] To prevent scratches on both sides of the door and window 400 during transportation, a vertical retainer 250 is provided between adjacent support units 220. The retainer 250 has a flexible pad on the side facing the accommodating space, and the retainer 250 has a vertical clearance groove 251. The clearance groove 251 is used to facilitate vertical movement at the hinge of the support unit 220.

[0057] Please see Figure 5 and Figure 6 As shown, considering the convenience requirements of the door and window 400 during loading and unloading, in some embodiments of the present invention, a clamping part 540 for clamping the frame of the door and window 400 is fixedly connected to the side of the rear active plate 530 facing the accommodating space 600. The clamping part includes a clamping opening 541 and elastic clamping wedges 542 provided on both sides of the clamping opening 541. Thus, after the protective frame assembly 200 is tightened along the length direction of the carriage, the clamping part 540 automatically clamps the rear frame of the door and window 400 through the elastic clamping wedges 542. After transportation, the door and window 400 can be disassembled. In addition to the rear stabilizing frame 700, the motor 160 is started to extend the protective frame assembly 200 along the length of the carriage. At this time, the door and window 400 will be automatically dragged to the rear end of the protective frame assembly 200 by the clamping part 540, which is conducive to the unloading of the door and window 400. In addition, with the aforementioned roller 240, the bottom frame of the door and window 400 is only subjected to a small rolling friction resistance from the roller 240. The clamping part 540 exerts a small pulling force on the door and window 400. The inner side of the elastic clamping wedge 542 can also be provided with a rubber pad, so it will not cause damage to the door and window 400.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
