Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of snow equipment, in particular to a covering layer for protecting and lubricating the surface of a snow airbag. BACKGROUND

[0002] The safety airbag used in the past ski (snow) jumping platform is generally composed of two parts. The first part is the airbag body used to buffer and protect the user landing. The other part is a layer of plastic cloth covering the surface of the airbag. This layer of plastic protects the airbag body from being cut or stabbed by the ski edges, causing the airbag body to leak and become unusable. Moreover, this layer of plastic cloth needs to provide good lubrication to facilitate the landing jumper to slide away.

[0003] However, in reality, no matter what material the plastic cloth is made of, its own cutting resistance is very limited, and it often needs to be repaired due to being cut. Moreover, the lubrication of this layer of plastic cloth is limited, and it needs to be continuously watered during use. In reality, the jumper often falls down after landing due to insufficient watering, and the board and plastic cloth rub too much, causing the board to pull the jumper's body, resulting in injuries to the jumper's body.

[0004] Moreover, the plastic cloth is not suitable for cold and hot climates, and often breaks, softens, and ages too quickly due to the climate, losing its protective effect on the airbag body and reducing lubrication. SUMMARY

[0005] The present application aims to overcome the above-mentioned problems and provide a covering layer for protecting and lubricating the surface of a snow airbag. Since the surface of the airbag is covered with one or more layers of plastic or cloth threads with a certain thickness, and a stab-resistant cloth is placed below the plastic or cloth threads, it is difficult for the ski board edges of the athlete to cut the airbag body below, which can effectively solve the problems in the background art.

[0006] To achieve the above-mentioned purposes, the present application provides the following technical solutions: a covering layer for protecting and lubricating the surface of a snow airbag, comprising a stab-resistant cloth, wherein the upper surface of the stab-resistant cloth is covered with a covering layer with a thickness of not less than 1 mm.

[0007] The stab-resistant cloth covers the surface of the airbag.

[0008] The covering layer is made of plastic or cloth threads or a mixture of the two, which are overlapped and staggered.

[0009] Preferably, the plastic or cloth threads that make up the covering layer are fixed together using a net rope.

[0010] Preferably, the plastic filaments or cloth filaments constituting the covering layer are fixed together by a cloth layer.

[0011] Preferably, the plastic filaments or cloth filaments constituting the covering layer are fixed on the cloth layer by an adhesive.

[0012] Preferably, the adhesive is polyurethane glue, butyl glue or silicone rubber glue.

[0013] Preferably, the plastic filaments or cloth filaments constituting the covering layer are of uniform diameter.

[0014] Preferably, the plastic filaments or cloth filaments are of arbitrary cross-sectional shape.

[0015] Preferably, the plastic filaments or cloth filaments are of elliptical or cylindrical cross-sectional shape.

[0016] Preferably, the plastic filaments or cloth filaments are of water-drop-shaped cross-sectional shape.

[0017] Preferably, the plastic filaments or cloth filaments are of polygonal cross-sectional shape.

[0018] Compared with the prior art, the present application has the following advantages:

[0019] 1. Since the air bag surface is covered with one or more layers of plastic filaments or cloth filaments with a thickness of 1-20 mm, and the plastic filaments or cloth filaments below are optionally backed with a puncture-proof cloth, it is difficult for the edges of the skis of the athletes to cut the air bag body below, thus preventing damage to the air bag body.

[0020] 2. The mixing of plastic filaments or cloth filaments with different properties and the rolling of the filament-like surface have the effect of resisting cutting by the edges of the skis.

[0021] 3. The filament-like surface is not a flat surface, and the skis do not contact it, thus preventing the increase in the sliding resistance of the skis due to the surface tension of the water and the charge attraction of the plastic cloth, which can cause injury to the user, greatly enhancing the sliding effect of the skis and protecting the user.

[0022] 4. Since the plastic filaments or cloth filaments are overlapped and interlocked, and different properties of plastic or cloth can be mixed, the weather resistance of the covering layer is improved, the service life of the covering layer is prolonged, and the economy of the site is improved.

[0023] 5. The plastic covering cloth used in the prior art cannot store water, and a large amount of water needs to be sprayed to ensure the lubrication of the surface, which is very wasteful. The overlapping and interlocking of the plastic filaments or cloth filaments can store a part of the water, thus achieving the effect of not needing to spray water all the time and saving energy and reducing emissions.

[0024] 6. The silk-like covering layer with a certain thickness has a certain softness, so as to further increase the protection effect of the air bag. BRIEF DESCRIPTION OF DRAWINGS

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Please refer to Figures 1-2 The present application provides the following technical solutions: a covering layer for protecting and lubricating the surface of an air bag.

[0033] Example 1: In this embodiment, it includes a stab-resistant cloth 1; the upper surface of the stab-resistant cloth 1 is paved with a covering layer 2 of 1-20 mm.

[0034] Specifically, since the covering layer 2 has good cutting resistance, the stab-resistant cloth 1 is fixed to the lower surface of the covering layer 2.

[0035] The stab-resistant cloth 1 covers the surface of the air bag.

[0036] Specifically, the setting of the stab-resistant cloth 1 makes it difficult for the edges of the skis of the athletes to cut the underlying air bag body, so as not to cause damage to the air bag body.

[0037] The covering layer 2 is made of plastic filaments or cloth filaments or a mixture of the two.

[0038] Specifically, the mixing of plastic filaments or cloth filaments with different properties and the rolling of the filament-like surface have the effect of cutting resistance of the covering layer itself to the edges of the skis.

[0039] Further, the plastic or cloth filaments that make up the covering layer 2 are fixed together using a net rope.

[0040] Specifically, because the plastic or cloth filaments are interlaced and fixed together using a net rope, they shield each other, and different types of plastic or cloth can be mixed and used, thereby improving the weather resistance of the covering layer, increasing the service life of the covering layer, and improving the economy of the site.

[0041] Please refer to Figure 3 The ends of the plastic or cloth filaments are fixed by the net rope.

[0042] Further, the plastic or cloth filaments that make up the covering layer 2 can be of the same diameter or different diameters.

[0043] Specifically, using filaments of the same diameter is convenient for manufacturing and maintenance, and using filaments of different diameters can increase the tightness of the covering layer 2, thereby increasing its service life.

[0044] Further, the plastic or cloth filaments have a cylindrical cross-section.

[0045] Specifically, the plastic or cloth filaments with a cylindrical cross-section can slide relative to each other when subjected to pressure, thereby providing a cushioning effect.

[0046] More specifically, the plastic or cloth filaments with a cylindrical cross-section have good water storage capacity.

[0047] Further, the plastic or cloth filaments have an elliptical cross-section.

[0048] Specifically, the plastic or cloth filaments with an elliptical cross-section have a greater density and better water storage capacity when combined.

[0049] Further, the plastic or cloth filaments have a water droplet-shaped cross-section.

[0050] Specifically, the plastic or cloth filaments with a water droplet-shaped cross-section can effectively reduce sliding resistance while providing some support effect.

[0051] Further, the plastic or cloth filaments have a rectangular, square, triangular, or trapezoidal cross-section.

[0052] Specifically, the covering layer made of plastic or cloth filaments with a polygonal cross-section makes the filament surface not flat, and when a snowboard contacts it, it will not increase the sliding resistance of the snowboard as before when it contacts a plastic cloth with water, due to the surface tension of the water and the charge attraction of the plastic cloth, which can cause injury to the user. This greatly enhances the sliding effect of the snowboard and protects the user.

[0053] Embodiment 2:

[0054] The difference between this embodiment and embodiment 1 is that in this embodiment, the plastic threads or cloth threads are fixed together by cloth layers. This arrangement can effectively improve the weather resistance of the covering layer, thereby improving the service life of the covering layer and the economy of the site.

[0055] In this embodiment, the anti-puncture cloth 1 is provided, and the upper surface of the anti-puncture cloth 1 is paved with a covering layer 2 of 1-20 mm.

[0056] Specifically, since the covering layer 2 has good cutting resistance, the anti-puncture cloth 1 is fixed to the lower surface of the covering layer 2.

[0057] The anti-puncture cloth 1 covers the surface of the air bag.

[0058] Specifically, the arrangement of the anti-puncture cloth 1 makes it difficult for the edges of the skis of the athletes to cut the air bag body below, and the air bag body is not damaged.

[0059] The covering layer 2 is made of plastic threads or cloth threads or a mixture of the two.

[0060] Specifically, the mixing of plastic threads or cloth threads with different properties and the rolling of the thread-like surface have the effect of cutting resistance of the covering layer itself.

[0061] Please refer to Figure 4 The plastic threads or cloth threads constituting the covering layer 2 are fixed together by cloth layers.

[0062] Specifically, the arrangement of the cloth layers can improve the water storage capacity and the impact resistance of the covering layer.

[0064] Further, the diameters of the plastic threads or cloth threads constituting the covering layer 2 can be the same or different.

[0065] Specifically, the use of threads with the same diameter facilitates production and maintenance, and the use of plastic threads or cloth threads with different diameters can increase the tightness of the covering layer 2, thereby improving its service life.

[0066] Further, the plastic threads or cloth threads have a cylindrical cross-section.

[0067] Specifically, the plastic threads or cloth threads with a cylindrical cross-section can slide with each other when subjected to pressure, thereby having a buffering effect.

[0068] More specifically, the plastic threads or cloth threads with a cylindrical cross-section have good water storage capacity.

[0069] Further, the cross section of the plastic thread or cloth thread is elliptical.

[0070] Specifically, the plastic thread or cloth thread with elliptical cross section can be more dense when combined together, and can have better storage capacity.

[0071] Further, the cross section of the plastic thread or cloth thread is water drop-shaped.

[0072] Specifically, the plastic thread or cloth thread with water drop-shaped cross section can effectively reduce the sliding resistance, while providing certain supporting effect.

[0073] Further, the cross section of the plastic thread or cloth thread is rectangular, square, triangular or trapezoidal.

[0074] Specifically, the covering layer composed of the plastic thread or cloth thread with polygonal cross section makes the thread-like surface not a flat surface, so that the ski board contacting with it will not increase the sliding resistance of the ski board due to the surface tension of water and the charge attraction of the plastic cloth, which may cause the injury of the user, thereby greatly enhancing the sliding effect of the ski board and protecting the user.

[0075] Embodiment 3:

[0076] The difference between this embodiment and embodiment 1 is that in this embodiment, the plastic thread or cloth thread constituting the covering layer 2 is fixed on the cloth layer by using adhesive, and the adhesive has certain elasticity, which can play a buffering role and further improve the comfort during landing.

[0077] In this embodiment, the anti-puncture cloth 1 is included; the upper surface of the anti-puncture cloth 1 is paved with a covering layer 2 of 1-20 mm.

[0078] Specifically, since the covering layer 2 has good cutting resistance, the anti-puncture cloth 1 is fixed on the lower surface of the covering layer 2.

[0079] The anti-puncture cloth 1 covers the surface of the air bag.

[0080] Specifically, the setting of the anti-puncture cloth 1 makes it difficult for the ski board edge of the athlete to cut the air bag body below, so as not to cause damage to the air bag body.

[0083] More specifically, the plastic threads or cloth threads are staggered by weaving.

[0084] Please refer toFigure 5 The plastic threads or cloth threads constituting the covering layer 2 are fixed on the cloth layer by using adhesive.

[0085] Specifically, the adhesive layer can improve the structural strength and elasticity.

[0086] More specifically, the adhesive only fixes the end and lower part of the plastic threads or cloth threads.

[0087] Further, the adhesive is selected from polyurethane glue, butyl glue or silicone rubber glue.

[0088] Specifically, by selecting the adhesive with wear resistance and elasticity, the service life of the covering layer 2 can be effectively improved.

[0089] Further, the diameters of the plastic threads or cloth threads constituting the covering layer 2 can be consistent or different.

[0090] Specifically, the consistent diameters facilitate the production and maintenance, and the different diameters can increase the tightness of the covering layer 2, thereby improving the service life.

[0091] Further, the plastic threads or cloth threads have a cylindrical cross section.

[0092] Specifically, the plastic threads or cloth threads with a cylindrical cross section can slide with each other when subjected to pressure, thereby achieving the buffering effect.
