DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0017] The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings.

[0018] Refer to FIGS. 1, 2, and 3 respectively for a perspective view of a reusable hanging device according to an embodiment of the present invention; a cross section view of a reusable hanging device according to an embodiment of the present invention; and a schematic view of reusable hanging device in usage according to an embodiment of the present invention.

[0019] As shown in FIGS. 1, 2, and 3, the reusable hanging device of the present invention mainly includes: an adhesion layer 11, a plate layer 12, and a hook body 13.

[0020] Wherein, the adhesion layer 11 is a low stickiness soft plastic made of a thermoplastic elastomer composite material, having the characteristic of rubber superb friction, and is provided with a smooth surface having smoothness of at least SP1(A3) (SP1(A3) is Ra 0.02 (surface roughness)). The adhesion layer can be vacuum-absorbed onto a smooth surface of a wall 20 (for example, surface of a glass wall, tile smooth surface having tiny bumps, smooth surface of iron gate having tiny bumps), to use the super strong friction force (slip-resistance force) created by the atmospheric pressure on the smooth surface of the wall 20.

[0021] The plate layer 12 is made of hard material, formed integrally on a surface of the adhesion layer 11.

[0022] The hook body 13 is also made of hard material, formed integrally on the surface of the plate layer 12 facing away from the adhesion layer 1. As such, the adhesion layer 11, the plate layer 12, and the hook body 13 formed integrally together into a reusable hanging device 10.

[0023] Through the structure mentioned above, in application, the adhesion layer 11 is absorbed onto the smooth surface of the wall 20 by means of vacuum, the super strong friction force (slip-resistance force) produced by the atmospheric pressure (as shown in FIG. 3) enables the hook body 13 to hang heavy object (0112.6 kgf). Also, the reusable hanging device 10 can be detached, and be reattached onto another smooth surface of a wall 20 as required, without damaging the wall surface or leaving any trace of attaching, in achieving the objective of the present invention.

[0024] In this way, the present invention is able to achieve the objective of changing attaching positions without damaging wall surface and leaving traces of attaching, while providing super strong adhesion for hanging heavy object.

[0025] Refer again to FIGS. 1 and 3. As shown in FIGS. 1 and 3, the surface of soft plastic for the adhesion layer 11 must be a smooth surface attaining at least SP1(A3) (SP1(A3) is Ra 0.02 (surface roughness)), or at least Ra 50 smoothness. In applying the reusable hanging device 10, it is attached outward by pressing the hook body 13, to squeeze the air out, so that the adhesion layer 11 utilizes atmospheric pressure to produce super strong friction force relative to the smooth surface of the wall 20 having or not having bumps (bump size less than 0.3 mm).

[0026] Refer again to FIG. 3, the reusable hanging device 10 is attached to the smooth surface of the wall 20 through the adhesion layer 11 by means of vacuum. The super strong friction force (slip-resistance force) thus produced enables the hook body 13 to be able to hang heavy object. Through SGS pulling force test, the capacity of hanging heavy object can reach as high as 112.6 kgf (as shown in attachment 1). In other words, the reusable hanging device 10 of the present invention is able to hang object of 0112.6 kgf, and that can not be achieved by the Prior Art. In the Prior Art, the hanging hook can only hang object of 030 kgf. In addition, in the present invention, the friction force (slip-resistance force) produced by the atmospheric pressure is utilized, so that when the size of the hook body 13 is enlarged or the number of the reusable hanging device 10 is increased, its object hanging capability may reach as high as several hundred kgfs.

[0027] Refer to FIG. 4 for a schematic view of reusable hanging device in usage according to another embodiment of the present invention. As shown in FIG. 4, the hook body 13 can be embedded into a locker 30. A connection head 31 is disposed on the locker 30, to engage the hook body 13, so that the locker 30 can be placed onto the reusable hanging device 10, for placing object therein.

[0028] In the following, refer to FIGS. 1, 2, and 3 for detailed descriptions of the reusable hanging device 10. As shown in FIGS. 1,2, and 3, the adhesion layer 11, the plate layer 12, and the hook body 13 can be formed integrally into a reusable hanging device 10 by means of double-ejection molding, insertion molding, or insertion and extrusion molding, depending on requirement.

[0029] As shown in FIGS. 1, 2, and 3, the adhesion layer 11 can be made of soft plastic composite adhesive material of industrial elastomer selected from one of the following group consisting of: TPEE, TPU, TPR, TPSIV, PVC, or Silicon.

[0031] As shown in FIGS. 1, 2, and 3, the hook body 13 can be made of hard material selected from one of the following group consisting of: PC, ABS, PP, PMMA, POM, NYLON, or plastics plus glass fiber.

[0032] As shown in FIGS. 1, 2, and 3, the thickness of soft plastics of the adhesion layer 11 is 0.310.0 mm, while the thickness of the plate layer 12 is 0.330.0 mm, in achieving raised hanging capacity though increased thickness.

[0033] As shown in FIGS. 1, 2, and 3, different thickness of adhesion layer 11 and plated layer 12 are matched in cooperation, to increase absorption capability on the surface of tiny bumps.

[0034] As shown in FIGS. 1, 2, and 3, the thickness of the plate layer 12 can be increased 0.330.0 mm, or reinforcement rib can be added, or adhesive glue or screw can be added to strengthen the plate layer 12, so as to increase the structure strength of the hook body 13. In addition, the thickness of the soft plastic adhesion layer 11 can be increased, to increase its absorption capability and weight hanging capability beyond that of the hanging hook presently available on the market.

[0035] As shown in FIGS. 1, 2, and 3, the hook body 13 is provided with dove tail groove or T-shape groove, for combining with various outside hanging hook, rod, or storage rack or cabin, to provide various hanging functions.

[0036] As shown in FIGS. 1, 2, and 3, around the edge of the adhesion layer 11 is provided with an unfilled corner 111, to facilitate the user to extend his finger or hand tool (for example, a flathead screwdriver) into the unfilled corner 111, to remove the adhesion layer 11 from the smooth surface of the wall 20.

[0037] As shown in FIGS. 1, 2, and 3, on the plate layer 12 is provided with at least a screw hole, to be used to lock an additional object, such as a multi-function connector head, a storage basket, a support rack, etc.

[0038] As shown in FIGS. 1, 2, and 3, around the plate layer 12 is provided with rim having thickness reduced to 0.4 mm, so that the hardness of the rim is reduced, to facilitate attaching the reusable hanging device 10 onto the smooth surface of the wall 20. Also, that makes easier to detach and remove the plate layer 12.

[0039] As shown in FIGS. 1, 2, and 3, around the plate layer 12 is wrapped a layer of soft plastic, to prevent water and moisture from seeping into the reusable hanging device 10. Further, it is used to prevent user's hand from being scratched when detaching and removing the plate layer 12.

[0040] As shown in FIGS. 1, 2, and 3, the contact between the plate layer 12 and the hook body 13 can be made into an arc surface or a slant surface, to strengthen the load hanging capacity of the reusable hanging device 10. Also, it can prevent the plate layer 12 from being damaged, when detaching and removing the reusable hanging device 10 from the smooth surface of the wall 20.

[0041] As shown in FIGS. 1, 2, and 3, tackifier can be added into the thermoplastic elastomer material, to increase the stickiness of the adhesion layer 11, and the weight hanging capacity of the reusable hanging device 10. The tackifier mentioned above can be one of the followings: Rosin ester, Terpene resinite, C5 Hydrocarbon Resin, Coumatone Resin, Aromatic Petroleum Resins, Styrenated, Acrylate Copolymer, other industrial tackifier, and elastomer having stickiness. With regard to the technology of adding tackifier into elastomer material, to increase the weight hanging capacity, refer to Chinese Patent Number CN102559112B.
