Technical Field
[0001] This utility model belongs to the field of warehousing and storage technology, specifically relating to a surface-type folding fence and an anti-piracy climbing device. Background Technology
[0002] Fences are sturdy, fence-like structures made of iron or wood strips, typically used for protection, but also applicable to toys and everyday items. A fence typically consists of at least three vertical bars and horizontal beams connecting adjacent bars to form a grid-like structure. Considering that fences are often stacked during actual storage and transportation, and that the presence of horizontal or vertical beams at adjacent layers can interfere with each other during stacking, the resulting multi-layered fences inevitably occupy considerable height, causing inconvenience in storage and transportation. This application addresses this issue by proposing a novel surface-type stackable fence that minimizes the stacking height while maintaining the daily functionality of each fence layer, thereby facilitating storage and transportation and ultimately maximizing cost-effectiveness. Summary of the Invention
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a surface-mounted folding fence that can minimize its stacking height while maintaining its basic performance, thus ensuring the convenience of warehousing and transportation operations.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A folding fence with a surface structure includes at least three fence surfaces; each fence surface includes at least three vertical bars, and adjacent vertical bars are connected by crossbeams; characterized in that: the crossbeams are concave and convex along the direction perpendicular to the fence surface to form an arch opening behind the vertical bar and an arch back around the front of the vertical bar respectively; when the fence surfaces are stacked so that the vertical bars are arranged alternately on the same surface, the crossbeams at each fence surface are arranged sequentially from top to bottom along the length direction of the vertical bar, at this time the slot width of the arch opening gradually narrows from top to bottom, so that the arch opening at the next fence surface can accommodate the corresponding vertical bars at the current layer and all previous fence surfaces, and the slot width of the arch back gradually widens from top to bottom.
[0006] Preferably, the crossbeam is an intermittent beam structure formed by the combination of sub-beams located between adjacent vertical bars; each sub-beam is shaped like a "Z"-shaped bar with a vertical angle, and two vertical bars arranged on the same plane are fixed at both ends of the sub-beam; when there are three or more vertical bars on the same grid surface, the adjacent ends of the adjacent sub-beams cooperate to clamp a vertical bar along the direction perpendicular to the grid surface.
[0007] Preferably, the crossbeam is a continuous beam structure formed by combining sub-beams located between adjacent vertical bars; each sub-beam is shaped like a "Z" with its corners vertically arranged, and two vertical bars arranged on the same plane are fixed at both ends of the sub-beam; when there are three or more vertical bars on the same grid surface, connecting blocks are provided at the adjacent ends of adjacent sub-beams to connect them into a whole structure; or the connecting blocks have mounting holes through which the vertical bars can pass and be fixed, or the vertical bars are fixed to the side of the connecting blocks.
[0008] Preferably, the number of vertical bars on each layer of the grid is the same, and the vertical bars on the grid are equidistant from each other and arranged in parallel.
[0009] Preferably, when the grid layers overlap on the same surface, the crossbeams on each grid layer are equidistant and arranged in parallel.
[0010] Preferably, the anti-piracy climbing device uses any of the above-mentioned surface-type folding fences, characterized in that: the same end of each fence surface is hinged to the same hinge axis, the axis of the hinge axis is perpendicular to the length direction of the vertical bar and parallel to the fence surface, so that after each fence surface is folded along the hinge axis, each fence surface overlaps, thereby making each vertical bar located on the same plane.
[0011] Preferably, it also includes a first end cover above the first layer of grid surface and a last end cover below the last layer of grid surface. Both covers include at least three vertical rods hinged to the hinge shaft, and the vertical rods are connected to each other by straight beams. When all covers and grid surfaces are folded up so that all vertical rods are on the same plane, the straight beam at the first end cover is located at the bottom of all the crossbeams and is arranged in the same plane as the groove back of each arch back, and the straight beam at the last end cover is located at the top of all the crossbeams and is arranged in the same plane as the groove bottom of all the arch openings.
[0012] Preferably, there are connecting parts between adjacent grid surfaces and between the corresponding grid surface and the adjacent cover surface, which are used to limit the expansion range between them; the connecting parts are connecting ropes, connecting chains or longitudinal folding rods; the longitudinal folding rods are two-section connecting rods with adjacent ends hinged to each other, and the two ends of the longitudinal folding rods are respectively hinged to the corresponding vertical rods, and the axis of each hinge of the longitudinal folding rod is parallel to the axis of the hinge.
[0013] Preferably, it also includes mounting rods arranged parallel to each other, with the hinge shaft mounted at the same end of the mounting rods; the hinge shaft is in the shape of a straight rod, and the vertical rods at each layer of the grid and all the cover surfaces are coaxially fitted onto the hinge shaft through the hinge hole at the tail end.
[0014] Preferably, the hinge shaft and the mounting rod together form a fixing frame, and the fixing frame is further included with a reserved mounting base for mounting the fixing frame; a handle is arranged on the front end cover and / or the rear end cover.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1) Through the above solution, this utility model provides a special folding structure for planar folding, enabling its application in folding applications of fences with vertical bars and horizontal beams. This utility model can be applied to everyday utensils, toys, fences, and even anti-piracy spikes, thereby ensuring their inherent performance while achieving planar or even curved folding effects through the special structure of the horizontal beams and the sequential staggered folding state, minimizing the stacking height and ensuring convenience for warehousing and transportation operations.
[0017] 2) The actual product application of this utility model will ultimately extend to anti-piracy operations. The applicant previously applied for a utility model patent with patent publication number "CN215972052U" entitled "A Cluster-type Pirate Protection Device," and on the same day, applied for a related invention patent. Therefore, this application can have hinge shafts inserted at the tail ends of each grid surface to achieve its protective effect; simultaneously, due to the existence of a specific beam structure, once the grid surfaces are staggered and folded, they can return to their original planar folded state. Ultimately, based on the original application, this further improves its volume after folding, enhances its convenience in storage, transportation, and installation, and ultimately maximizes its cost-effectiveness.
[0018] Thus, this utility model uses vertical rods as the foundation, horizontal beams as the link, and a single hinge axis as the rotation basis, thereby achieving a working state of "multiple rods forming a surface, multiple surfaces forming a cluster, and being able to be unfolded and stacked". In particular, considering that this utility model is based on a rotational structure of the same hinge axis, by controlling the thickness of the vertical rods and changing their arrangement, it is possible to achieve a flat or at least parallel stacking effect after the grid surface is folded up, so as to ensure its ease of use.
[0019] 3) As mentioned above, each layer of the grid can be very thin, and the mounting holes at the tail hinge are positioned to ensure that they are coaxial with each other, which can achieve a stacked state in which multiple grids are stacked in parallel one after another.
[0020] 4) For the crossbeams at the grid surface, due to their specific shape, there are multiple ways to connect them with the corresponding vertical bars. For example, a direct bar-face fixing method can be used, in which case adjacent ends of adjacent sub-beams at the same grid surface will clamp a vertical bar. Alternatively, a pre-set connecting block method can be used to ensure the connection effect between the vertical bar and the crossbeam.
[0021] 5) In actual design, this utility model also adds a front end cover and a rear end cover to ensure ease of opening and closing.
[0022] 6) The arrangement of the mounting rods serves to directly connect to the installation points on the ship; for example, they can be directly fixed to the ship's railings by clips, or fixed to the pre-set base on the ship's hull by bolts, etc.
[0023] 7) The arrangement of the connecting parts is designed to achieve a "one-size-fits-all" effect, ensuring that once the first end cover is lifted by the handle, all the grilles open sequentially due to the presence of the connecting parts, further improving the ease of opening. Of course, the connecting parts can be of various types, as long as they can achieve the above-mentioned linkage effect.
[0024] 8) When necessary, this utility model also includes a reserved mounting base, the purpose of which is to install the reserved mounting base in advance in areas where the installation area is located on the deck surface or other areas where installation is not possible, and to achieve the expected protection and disassembly purpose by quickly assembling and disassembling the fixed frame, so as to ensure its flexibility of use.

[0039] In practical use, this utility model can either use multiple layers of grid surfaces 10 working together to achieve the desired planar folding requirement; or it can be used with the first end cover surface 30 and the last end cover surface 40 to achieve double-end clamping folding; of course, for the latter, this utility model further provides... Figures 8-11 The specific embodiments shown are as follows.
[0040] Furthermore, it is worth noting that in this invention, the vertical rod a can be formed by a single rod or by multiple rods fixed side by side, ultimately ensuring that a single or group of vertical rods a can fit into the corresponding arch opening 11a. Similarly, although the grid surface 10 can be curved or other irregularly shaped, as long as it is planar, it can be stacked using the concept of this invention to form a single surface; of course, it is preferable to still use the planar grid surface 10 described in this invention to ensure that the dimensions in terms of spatial height are minimized after stacking.
[0041] Furthermore, since the anti-piracy climbing device combines a front end cover 30, a fence surface 10, and a rear end cover 40, it also features different connection structures for the crossbeam 11 and the straight beam b. Therefore, for the sake of effective description, this section combines... Figures 1-11 Taking the specific structure and working method of the anti-piracy climbing device used in this utility model as an example, the detailed structure of this utility model is described in detail below:
[0042] like Figures 1-2 As shown, a specific embodiment of this utility model includes the aforementioned first end cover 30, grid surface 10, and tail end cover 40. The first end cover 30 and tail end cover 40 have an overall sealing effect on both the outer and inner sides, stabilizing the coplanar state of the stacked grid surfaces 10 through the clamping effect of the two covers. Specifically, each cover includes four spear-shaped vertical rods a, connected to each other by a single straight beam b, thereby forming... Figure 3 and Figure 5 The structural state is as follows. Correspondingly, the grid surface 10 located between the two cover surfaces is formed by connecting four spear-shaped vertical rods a to each other via a crossbeam 11 of a specific shape. The grid surface 10 and the corresponding cover surface are then subsequently mounted on the hinge shaft 21 of the fixing frame 20 through the tail hinge hole b1. Figure 2Taking the example of ten rows of grilles 10 and two rows of covers, they are sequentially hinged to the same hinge axis 21 of the fixing frame 20 using the tail hinge hole b1. Then, longitudinal folding linkage-type connecting parts are installed between adjacent grilles 10 to ensure a linkage effect. Of course, the tail cover 40 of this invention shown in the figure is directly integrated with the fixing frame 20; that is, the tail cover 40 itself may not exist and can be integrated with the fixing frame 20 into a single structure. Even in a single structure, the aforementioned connecting parts should be arranged between the tail cover 40 and the adjacent grilles 10. The same applies when the head cover 30 is used as part of the fixing frame 20. In this way, this invention can be quickly deployed to defend against pirates and can also be easily stored.
[0043] In addition to the hinge shaft 21, the fixed frame 20 is also equipped with a mounting rod 22 to facilitate climbing and installation on a base such as a railing.
[0044] The shape of the straight beam b at the first end cover 30 and the last end cover 40 is referenced. Figure 3 and Figure 5 As shown, it simply requires welding a straight beam to the corresponding side. However, if the goal is to create a thin, flat surface after storage, the crossbeam 11 at the grid surface 10 needs to be made in a special shape, with at least the following specific methods: Figure 4 , Figure 7 and Figure 8 Three implementation methods. Figure 4 and Figure 7 In the diagram, it can be seen that the crossbeam 11 at the grid surface 10 is divided into several sub-beams 11c, and the sub-beams 11c are in... Figure 6 The nesting relationship is evident, meaning the arch opening 11a of the current grid surface 10 can engage with the corresponding single vertical rod a of all preceding grid surfaces 10; in other words, the vertical rods a of all preceding grid surfaces are correspondingly nested within their respective arch openings 11a. Simultaneously, the arch back 11b ensures that each grid surface can only open sequentially in a single direction. Of course, if necessary, the engagement position of the vertical rod a and the sub-beam 11c can be adaptively adjusted, such as by using… Figure 7 The connecting block 12 is shown. The width of the slot of the bow 11a gradually narrows from top to bottom, meaning that the width of the bow 11a slot at the lower layer of crossbeam 11 is always smaller than the width of the bow 11a slot at the upper layer of crossbeam 11; the same applies to the bow back 11b. In this way, when stacked, this utility model allows the vertical rods a in the same row to rise and fall synchronously. At the same time, when all the vertical rods a are folded up, the vertical rods a in each row can be placed in an interlaced manner, and the crossbeams 11 will not interfere with each other. The entire device can be folded into a thin flat plate, which can maximize space saving when stored in the cabin and also improve the stability when different devices are stacked. Figure 8 As can be seen, the crossbeam 11 forms an integrated structure and can also achieve its intended function.
[0045] In actual design, a motor can be added to the vertical rod a, and a reciprocating motion mechanism can be installed. A secondary rod with spikes at the head or an additional discharge device can improve the protective effect.
[0046] When necessary, this utility model can not only be installed on existing ship railings, but also directly on the ship's hull surface, or even pre-installed on the deck at important entrances and exits. In case of danger, this utility model can be quickly installed and deployed to serve as a last line of defense.
[0047] According to calculations, each unit of this utility model weighs 6-7 kg, can be carried by one person and installed by two people, and is very convenient and quick to use.
[0048] The specific operating procedure of this anti-piracy climbing device includes:
[0049] Before entering dangerous waters, remove folded items from the hold. Figure 1 The present invention, as shown, is subsequently pre-installed on the railing or other parts of the vessel's exterior using fasteners, straps, wires, or bolts. Upon entering dangerous waters, gripping the handle 50 degrees and applying force will then secure the present invention as shown. Figure 9-11 As shown in the diagram, when unfolded and fixed, each vertical rod a resembles a spear, transforming any climbable part of the ship into a steel hedgehog, leaving pirates nowhere to climb. This densely arranged installation achieves excellent anti-hijacking effectiveness. After the ship leaves the dangerous waters, this invention can be folded back up to form a thin flat surface, then disassembled piece by piece and placed back into the hold. This does not hinder normal navigation and occupies very little storage space; furthermore, due to the folded shape... Figure 6 The thin, flat final storage configuration shown makes it very convenient to stack and store inside the cabin, greatly improving space utilization and offering high cost-effectiveness.
[0050] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar methods that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
