Description

Technical Field

[0001] The invention belongs to the technical field of warehouse storage, and in particular relates to a surface-type folding fence and an anti-pirate climbing device. Background Art

[0002] A fence is a relatively sturdy structure similar to a fence made of iron bars or wooden bars, which is usually used for protection. Of course, it can also be used in occasions such as toys or daily utensils. The structure of the fence includes at least three vertical bars and a crossbeam connecting adjacent vertical bars to form a fence surface structure. Considering that fences are often accompanied by cumulative operations during actual storage and transportation, and because the presence of crossbeams or vertical bars at adjacent layers of fences will interfere with each other's positions when stacked, the multi-layer fences after folding will inevitably occupy a certain space height, ultimately causing inconvenience in storage and transportation. Based on this, the present application proposes a new type of surface-type folding fence, so that while ensuring the daily use function of each fence, its stacking height is minimized to achieve the convenience of storage and transportation, and ultimately maximize the cost performance. Summary of the invention

[0003] The object of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a flat folding fence which can minimize its stacking height while maintaining its own basic performance, thereby ensuring the convenience of storage and transportation operations.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A flat folding fence comprises at least three layers of fence surfaces; each layer of fence surfaces comprises at least three vertical bars, and adjacent vertical bars are connected by crossbeams; the characteristic is that the crossbeams are concave and convex along the direction perpendicular to the fence surfaces, thereby respectively forming an arch mouth that goes around the rear of the vertical bars and a arch back that goes around the front of the vertical bars; when the layers of fence surfaces are overlapped so that the vertical bars are arranged in sequence and staggered on the same surface, the crossbeams at each layer of fence surfaces are arranged in sequence from top to bottom along the length direction of the vertical bars, and at this time, the width of the notch of the arch mouth gradually narrows from top to bottom, so that the arch mouth at the next layer of fence surfaces can accommodate the corresponding vertical bars at the current layer and all the previous fence surfaces, and the width of the notch of the arch back gradually widens from top to bottom.

[0006] Preferably, the crossbeam is an intermittent beam structure formed by a combination of sub-beam bodies located between adjacent vertical rods; the outer shape of each sub-beam body is a "Z"-shaped rod body arranged vertically at the corner, and two vertical rods arranged in the same plane are respectively fixed at the two ends of the sub-beam body; when there are more than three vertical rods at the same grid surface, adjacent ends of adjacent sub-beam bodies cooperate to clamp a vertical rod in a direction perpendicular to the grid surface.

[0007] Preferably, the crossbeam is a continuous beam structure formed by a combination of sub-beam bodies located between adjacent vertical rods; the outer shape of each sub-beam body is a "Z"-shaped rod body arranged vertically at the corner, and two vertical rods arranged in the same plane are respectively fixed at the two ends of the sub-beam body; when there are more than three vertical rods at the same grid surface, adjacent ends of adjacent sub-beam bodies are provided with connecting blocks connecting each other, so as to connect the adjacent sub-beam bodies into an integral structure; or the connecting blocks are penetrated with mounting holes for the vertical rods to be inserted and fixed, or the vertical rods are fixed to the sides of the connecting blocks.

[0008] Preferably, the number of vertical bars on each grid surface is the same, and the vertical bars on the grid surface are equidistant from each other and arranged in parallel.

[0009] Preferably, when the grid surfaces of each layer overlap on the same plane, the cross beams on each grid surface are equidistant and arranged in parallel.

[0010] Preferably, an anti-pirate climbing device is applied with a surface-type folding fence as described in claim 1, characterized in that the same end of each layer of the fence surface is hinged on the same hinge shaft, and the axis of the hinge shaft is perpendicular to the length direction of the vertical rod and parallel to the fence surface, so that after each layer of the fence surface is folded along the hinge shaft, each layer of the fence surface overlaps so that each vertical rod is located on the same plane.

[0011] Preferably, it also includes a head end cover surface located above the first layer of grid surfaces and a tail end cover surface located below the last layer of grid surfaces, both cover surfaces include at least three vertical rods hinged on the hinge axis, and the vertical rods are connected to each other by straight beams; when all the cover surfaces and grid surfaces are folded so that all the vertical rods are located on the same plane, the straight beam at the head end cover surface is located at the bottom of all the cross beams and is arranged in the same plane as the groove backs of each bow back, and the straight beam at the tail end cover surface is located at the top of all the cross beams and is arranged in the same plane as the groove bottoms of all the bow mouths.

[0012] Preferably, connecting parts for limiting the expansion range between the two are arranged between adjacent grid surfaces and between corresponding grid surfaces and adjacent cover surfaces; the connecting parts are connecting ropes or connecting chains or longitudinal folding connecting rods; the longitudinal folding connecting rods are two-section connecting rods with adjacent ends hinged to each other, and the two ends of the longitudinal folding connecting rods are respectively hinged to corresponding vertical rods, and the axes of each hinge of the longitudinal folding connecting rod are parallel to the axis of the hinge shaft.

[0013] Preferably, it also includes installation rods arranged parallel to each other, and the hinge shaft is installed at the same end of the installation rods; the hinge shaft is in the shape of a straight rod, and the vertical rods at each layer of the grid surface and all the cover surfaces are coaxially matched to the hinge shaft through the tail end hinge holes.

[0014] Preferably, the hinge shaft and the mounting rod together form a fixing frame, which also includes a reserved mounting base for mounting the fixing frame; and a handle is arranged on the head end cover surface and / or the tail end cover surface.

[0015] The beneficial effects of the present invention are:

[0016] 1) Through the above scheme, the present invention provides a special folding structure for flat folding, so that it can be applied to the folding occasions of fences with vertical bars and horizontal beams. When used in daily utensils, toys, fences, and even anti-pirate thorns, the present invention can be applied thereto, so that while ensuring its inherent performance, through the special structure of the horizontal beam and the sequentially staggered folding state, a flat or even curved folding effect is achieved to minimize its stacking height and ensure the convenience of storage and transportation operations.

[0017] 2) The actual product application of the present invention will eventually radiate to anti-piracy operations. The applicant has applied for a utility model patent with the patent announcement number "CN215972052U" and the patent name "A cluster-type pirate protection device", and applied for a related invention patent on the same day. To this end, the present application can provide a hinge shaft at the tail end of each grille surface to achieve its protection effect; at the same time, due to the existence of a specific crossbeam structure, once the grille surfaces are staggered and folded, they can return to the original flat folded state, and finally based on the original application, further improve its volume state after folding, improve its convenience in warehousing, transportation and installation, and ultimately achieve maximum cost-effectiveness.

[0018] So far, the present invention is based on vertical rods, horizontal beams as links, and a single hinge axis as a rotation basis, thereby realizing a working state of "multiple rods forming a surface, multiple surfaces forming a cluster, which can be expanded and folded". In particular, considering that the present invention is a rotating structure based on the same hinge axis, by controlling the thickness of the vertical rods, changing their arrangement, etc., it is possible to achieve a folding effect in which the grid surfaces are in the same plane after folding, or at least are parallel to each other, to ensure its ease of use.

[0019] 3) As mentioned above, each layer of the grid surface can be very thin, and the positions of the mounting holes at the hinged end are ensured to be coaxial with each other, so that the folding state of multiple layers of grid surfaces can be achieved by stacking them in parallel one by one.

[0020] 4) For the horizontal beam at the grid surface, due to its specific shape, there are many ways to cooperate with the corresponding vertical rod. For example, if the method of direct rod surface fixing is adopted, at this time, the adjacent ends of adjacent sub-beams at the same grid surface cooperate to clamp a vertical rod. It is also possible to use a preset connection block to ensure the connection effect between the vertical rod and the horizontal beam.

[0021] 5) In actual design, the present invention further provides a head end cover and a tail end cover to ensure convenience during opening and closing.

[0022] 6) The arrangement of the mounting rod serves the function of directly connecting the installation point on the ship; for example, it is directly fixed to the hull railing by buckles, or fixed to the preset base of the hull by bolts, etc.

[0023] 7) The arrangement of the connection part is used to achieve the effect of "a single move affects the whole body", so as to ensure that once the head cover is lifted by the handle, all the grille surfaces are opened one by one in sequence due to the existence of the connection part, so as to further improve the convenience of opening. Of course, the connection part can be of various connection structures, as long as it can achieve the above linkage effect.

[0024] 8) If necessary, the present invention also includes a reserved installation base. The purpose is that when the installation area is located in an area that cannot be installed, such as the deck surface, the reserved installation base can be installed in the area in advance, and later it can be directly quickly disassembled and assembled with the fixing frame to achieve the expected protection and disassembly purposes, thereby ensuring its flexibility of use.

[0039] When the present invention is actually used, it is possible to use only multiple layers of grid surfaces 10 to cooperate with each other to achieve the predetermined planar folding requirement; it is also possible to cooperate with the head end cover surface 30 and the tail end cover surface 40 to achieve the double-end clamping folding purpose; of course, for the latter, the present invention further provides Figure 8-Figure 11 The specific embodiment shown.

[0040] In addition, it is worth mentioning that: in the concept of the present invention, the vertical rod a can be formed by a single rod body, or multiple rod bodies fixed side by side to form an integral body, and finally it is sufficient to implement a single rod or a single group of vertical rods a that can be placed in the corresponding arch opening 11a. Similarly, although the grid surface 10 can be a curved surface or other special-shaped surface, as long as it is a surface, it can be overlapped to form a single surface using the concept of the present invention; of course, it is preferred to still use the flat grid surface 10 described in the present invention to ensure that the size of the space height after folding is minimized.

[0041] Furthermore, since the anti-pirate climbing device has the head end cover 30, the grid surface 10 and the tail end cover 40, it also has different connection structures of the cross beam 11 and the straight beam b. Figure 1-Figure 11 , directly taking the specific structure and working mode of the anti-pirate climbing device used in the present invention as an example, the detailed structure of the present invention is described in detail as follows:

[0042] like Figure 1-Figure 2 As shown, the specific embodiment of the present invention includes the aforementioned head cover 30, the grid surface 10 and the tail cover 40. The head cover 30 and the tail cover 40 have an overall sealing effect on the outside and inside, so as to stabilize the coplanar state of each layer of grid surface 10 after superposition through the clamping effect of the two covers. In the specific design, the two covers each include four spear-shaped vertical rods a, and rely on a whole straight beam b to connect each other, so as to form Figure 3 and Figure 5 Correspondingly, the grille surface 10 between the two covers is connected to each other by four spear-shaped vertical rods a through a crossbeam 11 of a specific shape to form a layer of grille surface 10. The grille surface 10 and the corresponding cover are then mounted on the hinge shaft 21 of the fixing frame 20 through the rear end hinge hole b1. Figure 2Taking the example of ten rows of grille surfaces 10 and two rows of cover surfaces, the tail end hinge holes b1 are sequentially used to hinge at the same hinge shaft 21 of the fixing frame 20; then the longitudinal folding connecting rod type connecting parts are successively installed between the two adjacent grille surfaces 10 to ensure the linkage effect. Of course, the tail end cover surface 40 of the present invention shown in the figure is directly formed integrally with the fixing frame 20, that is, the tail end cover surface 40 itself may not exist, and can be integrated with the fixing frame 20 into an integral structure; and even if it is an integral structure, the above-mentioned connecting part should be arranged between the tail end cover surface 40 and the adjacent grille surface 10; when the head end cover surface 30 is used as a part of the fixing frame 20, it is also the same. In this way, the present invention can be quickly deployed to resist pirates, and can also be folded for convenient storage.

[0043] In addition to the hinge shaft 21, the fixing frame 20 is also provided with a mounting rod 22 so as to facilitate the mounting on a base such as a railing.

[0044] The appearance of the straight beam b at the head end cover 30 and the tail end cover 40 is shown in FIG. Figure 3 and Figure 5 As shown, it is only necessary to weld a whole straight beam body at the corresponding side. However, if it is considered that the plane can be as thin as possible after being stored, the cross beam 11 at the grid surface 10 needs to be made in a special shape, and the specific formation method has at least Figure 4 , Figure 7 and Figure 8 There are three ways to implement it. Figure 4 and Figure 7 In FIG. 1 , it can be seen that the cross beam 11 at the grid surface 10 is divided into several sub-beam bodies 11c, and the sub-beam bodies 11c are Figure 6 It can be seen that the nesting relationship between them is that the arch 11a of the current grid surface 10 can be inserted into the corresponding single vertical rod a of all the previous grid surfaces 10; in other words, the vertical rods a of all the previous grid surfaces are correspondingly pillowed in the corresponding arch 11a. At the same time, the arch back 11b is used to ensure that each grid surface can only be opened one by one in a single direction. Of course, if necessary, the matching position of the vertical rod a and the sub-beam body 11c can be adaptively adjusted, such as using Figure 7 The connecting block 12 shown in the figure. The slot width of the bow mouth 11a is gradually narrowed from top to bottom, which means that the slot width of the bow mouth 11a at the lower beam 11 is always smaller than the slot width of the bow mouth 11a at the upper beam 11; the same is true for the bow back 11b. In this way, when stacked, the present invention can make the vertical rods a in the same row rise and fall synchronously, and at the same time, when all the vertical rods a are folded and retracted, the vertical rods a in each row can be staggered with each other, and the beams 11 will not interfere with each other. The whole device can be folded to form a thin flat plate, which can save space to the maximum extent when stored in the cabin, and can also improve the stability when different devices are stacked. Figure 8 It can be seen that the cross beam 11 forms an integrated structure and can also achieve the intended function.

[0045] In actual design, the vertical rod a can also be equipped with a motor, and a forward and backward reciprocating motion mechanism can be added. A secondary rod with spikes on the head or an additional discharge device can enhance the protection effect.

[0046] When necessary, the present invention can be installed not only on a predetermined ship railing, but also directly on the surface of the hull, or even with a reserved mounting base pre-installed on the deck at an important entrance and exit position, so that the present invention can be quickly installed and deployed in danger to serve as the last line of defense.

[0047] According to calculation, a single device of the present invention weighs 6-7 kilograms, can be carried by one person, and can be installed by two people, so it is very convenient and quick to use.

[0048] The specific operation process of the anti-pirate climbing device of the present invention includes:

[0049] Before entering dangerous waters, take out the folded Figure 1 The present invention in the state shown is then pre-installed on the railings or the like outside the ship by means of buckles, straps, steel wires or bolts. After entering the dangerous sea area, the handle 50 is gripped and force is applied to thereby install the present invention as shown in FIG. Figure 9-11 As shown in the unfolding and fixing, each vertical rod a is like a spear, which can turn the climbing area of ​​the whole ship into a steel hedgehog, leaving pirates with nowhere to climb. The densely arranged installation of the present invention can achieve an excellent anti-hijacking effect. After the ship leaves the dangerous sea area, the present invention can be folded up again to form a thin plane, and then disassembled one by one and put back into the cabin. This will not hinder the normal navigation of the ship, and will only take up a small amount of storage space on the ship when stored; and because the folded Figure 6 The final storage state of the thin sheet shown is also very convenient for stacking and storage in the cabin, which greatly improves the space utilization and has high cost performance.
