DETAILED DESCRIPTION

[0038] In the following detailed description of the embodiments, reference is made to the accompanying drawings that form a part hereof. The drawings show, by way of example, specific embodiments in which the invention is embodied. The embodiments shown are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. With respect to the figures, directional terms, such as lower, upper, left, right, and the like, are used with reference to the orientation of the figure being described. Since the components of embodiments of the present invention can be implemented in a variety of orientations, these directional terms are used for purposes of illustration and not for purposes of limitation. Therefore, the following detailed description of the embodiments is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.

[0039] In a first aspect, with reference to FIGS. 1, 2, 3, 4 and 5, an anti-collision strip 1 provided by an embodiment of the present invention comprises a first side edge mounting portion 2, an intermediate portion 3 and a second side edge mounting portion 4 connected in sequence along a width direction of the anti-collision strip 1, and the first side edge mounting portion 2, the intermediate portion 3 and the second side edge mounting portion 4 extend along a length direction of the anti-collision strip 1, wherein a first inner side groove 5 extending along the length direction of the anti-collision strip is formed at a junction of a first inner side surface 21 of the first side edge mounting portion 2 and an intermediate inner side surface 31 of the intermediate portion 3, and a second inner side groove 6 extending along the length direction of the anti-collision strip is formed at a junction of a second inner side surface 41 of the second side edge mounting portion 4 and the intermediate inner side surface 31 of the intermediate portion 3.

[0040] In the anti-collision strip 1, as the first inner side groove 5 extending along the length direction of the anti-collision strip 1 is formed at the junction of the first inner side surface 21 and the intermediate inner side surface 31, and the second inner side groove 6 extending along the length direction of the anti-collision strip 1 is formed at the junction of the second inner side surface 41 and the intermediate inner side surface 31, the first inner side groove 5 and the second inner side groove 6 can provide effective buffer space to avoid squeezing the junction between the first side edge mounting portion 2 and the intermediate portion 3 and the junction between the second side edge mounting portion 4 and the intermediate portion 3, so as to reduce the resilience of the anti-collision strip 1, and to allow the first side edge mounting portion 2 and the second side edge mounting portion 4 to have a larger space for being turned-out with respect to the intermediate portion 3. For example, when the corner has an angle smaller than the angle A between the first inner side surface and the second inner side surface of the anti-collision strip, the buffer space provided by the first inner side groove 5 and the second inner side groove 6 can prevent the junction between the first side edge mounting portion 2 and the intermediate portion 3 and the junction between the second side edge mounting portion 4 and the intermediate portion 3 from being squeezed, so as to reduce the resilience of the anti-collision strip, thereby reducing or avoiding the possibility of peeling of the anti-collision strip due to excessive resilience in the mounted state, particularly in the 90 mounted state. When the corner has an angle larger than the angle A between the first inner side surface 21 and the second inner side surface 31 of the anti-collision strip, the buffer space provided by the first inner side groove 5 and the second inner side groove 6 may allow the first side edge mounting portion 2 and the second side edge mounting portion 4 to have a larger space for being turned-out with respect to the intermediate portion 3, so as to avoid tearing the junction between the first side edge mounting portion 2 and the intermediate portion 3, and the junction between the second side edge mounting portion 4 and the intermediate portion 3, and to allow the anti-collision strip to be adhered more closely to the corner. Therefore, the anti-collision strip can be stably and reliably adhered on corners, and peeling due to resilience can be avoided, which has a good protective effect for the edge of the corner and improves the convenience of use.

[0041] Furthermore, in some embodiments, the intermediate portion 3 of the anti-collision strip 1 of the present invention may be formed with a plurality of grooves arranged at intervals in the width direction of the anti-collision strip 1 and extending along the length direction of the anti-collision strip 1.

[0042] Furthermore, in some embodiments, due to the presence of the first and second inner side grooves 5 and 6, it is possible to avoid the formation of a plurality of grooves as in the prior art on the intermediate portion 3, which ensures the sufficient thickness of the intermediate portion 3, that is, local part in the intermediate portion which has too thin thickness can be avoided, such that the anti-collision strip 1 only needs to be wrapped around the edges of the corners during installation. In addition, due to the presence of the first and second inner side grooves 5 and 6, not only can the anti-collision strip be suitable for corner protection of various angles, but also the user can easily break the first side edge mounting portion 2 and the second side edge mounting portion 4 to both sides, thereby facilitating the adhesion of the double-sided tape to the first inner side surface 21 and the second inner side surface 41, and improving the convenience of use. Therefore, the anti-collision strip 1 can be stably and reliably adhered to the corner, and peeling due to the resilience can be avoided, which has a further excellent protective effect for the edge of the corner, and improves the convenience of use.

[0043] In addition, in the anti-collision strip 1 of the present invention, the overall thickness of the anti-collision strip 1 can be flexibly adjusted according to practical requirements, that is to say, the overall thickness of the anti-collision strip 1 can be increased or decreased, as long as the required thickness of the intermediate portion 3 is ensured and the local part in the intermediate portion 3 which has too thin thickness is avoided. For example, in some embodiments, the intermediate portion 3 is formed with a plurality of grooves arranged at intervals in the width direction thereof and extending along the length direction thereof, but the thickness of the intermediate portion 3 at the grooves also satisfies the desired thickness.

[0044] In the anti-collision strip 1 of the present invention, in the natural state of the anti-collision strip, the angle A between the first inner side surface 21 and the second inner side surface 41 may be any appropriate angel value. For example, it may be less than 90, equal to 90 or greater than 90.

[0045] For example, in some embodiments, the angle A between the first inner side surface 21 and the second inner side surface 41 satisfies: 90angle A180. For example, in embodiments where the angle A is any value greater than 90, the anti-collision strip may be further adapted for corner protection at various angles. For example, in some embodiments, the angle A between the first inner side surface 21 and the second inner side surface 41 is greater than 135, which may further facilitate the application of double-sided tape to the first inner side surface 21 and the second inner side surface 41, and especially facilitate the automatic pre-application of double-sided tape to the first inner side surface 21 and the second inner side surface 41 by a machine, thereby improving the production efficiency, ensuring the consistency of double-sided tape application, and reducing the cost and quality defects of manual application.

[0046] Furthermore, in some embodiments, referring to FIGS. 1, 2 and 3, the angle A between the first inner side surface 21 and the second inner side surface 41 is equal to 180, that is, the anti-collision strip 1 is formed as a planar anti-collision strip. In this way, since the first inner side surface 21 and the second inner side surface 41 are arranged in a plane in a natural state of the anti-collision strip, it is easy to adhere the double-sided tape to the first inner side surface 21 and the second inner side surface 41, and in particular, it is further convenient for the machine to automatically pre-adhere the double-sided tape to the first inner side surface 21 and the second inner side surface 41, and in addition, it is also convenient to naturally bundling the anti-collision strip to reduce a storage space and to facilitate package transportation.

[0047] In addition, it needs to be stated here that the anti-collision strip 1 of the present invention do not have to be packed, stored and transported in a rolled manner. For example, in some embodiments, the anti-collision strip 1 may also have a preset length and be stored, packaged, and transported in a naturally spread manner.

[0048] Further, the angle A between the first inner side surface 21 and the second inner side surface 41 in the mounted state of the anti-collision strip may be any suitable angle value from 0 to 180. For example, for very thin flat edges (e.g. flat edges of glass or steel plate), the first inner side surface 21 and the second inner side surface 41 of the anti-collision strip are parallel to each other in the mounted state, in which case the angle A between the first inner side surface 21 and the second inner side surface 41 may be 0. As another example, when the anti-collision strip is installed flat on a plane to be protected, the first inner side surface 21 and the second inner side surface 41 of the anti-collision strip will be located on the same plane, in which case the angle A between the first inner side surface 21 and the second inner side surface 41 may be 180. As another example, for a 90 edge, the angle A between the first inner side surface 21 and the second inner side surface 41 may be 90 in the mounted state. As another example, for edges less than 90, the angle A between the first inner side surface 21 and the second inner side surface 41 may be an acute angel (e.g. 30. 45, or 60) in the mounted state. As another example, for edges greater than 90, the angle A between the first inner side surface 21 and the second inner side surface 41 may be an obtuse angle (e.g. 120. 135, or 150) in the mounted state.

[0049] In addition, in the anti-collision strip 1 of the present invention, the first inner side groove 5 and the second inner side groove 6 may have any desired depth, that is, the distance from an opening portion of the groove to a bottom thereof, for example, in some embodiments, the depth of the first inner side groove 5 and the second inner side groove 6 is 0.2 cm-0.4 cm. In some embodiments, the first inner side groove 5 and the second inner side groove 6 have a depth of 0.3 cm. Further, the first inner side groove 5 and the second inner side groove 6 may have the same depth or may have different depths.

[0050] Furthermore, in the anti-collision strip 1 of the present invention, the cross-sectional shapes of the first inner side groove 5 and the second inner side groove 6 may have any desired shape, for example, in some embodiments, the cross-sectional shapes of the first inner side groove 5 and the second inner side groove 6 include a V-shape (e.g. the V-shape shown in FIGS. 2 and 3), a U-shape, or a semicircular shape. The V-shape. U-shape or semicircular shape not only facilitates shaping, but also forms an arc-shaped transition at the bottom of the groove, which avoids tearing the anti-collision strip at the first inner side groove 5 and the second inner side groove 6. Of course, the cross-sectional shapes of the first inner side groove 5 and the second inner side groove 6 are not limited thereto, and may be rectangular, trapezoidal, or other shapes.

[0051] In addition, in some embodiments of the anti-collision strip of the present invention, the anti-collision strip is not previously adhered with double-sided tape, and the anti-collision strip without double-sided tape can be used as a finished product or a semi-finished product; after being purchased by a user, the double-sided tape can be adhered on the first inner side surface 21 and the second inner side surface 41 by the user, or after being purchased by other manufacturers, the double-sided tape can be adhered on the first inner side surface 21 and the second inner side surface 41 by a machine, and then to be sold as a product thereof.

[0052] In some embodiments, referring to FIG. 3, an adhesive layer 10 having a tearable protective film is formed on the first inner side surface 21 and the second inner side surface 41. In FIG. 3, the adhesive layer 10 is not directly illustrated because the thickness of the adhesive layer 10 adhered to the first inner side surface 21 and the second inner side surface 41 is thin. In this way, the user's step of applying the double-sided tape can be effectively avoided, thereby improving the convenience of use. After the user purchasing, the protective film can be easily torn off, and then the first inner side surface 21 and the second inner side surface 41 are adhered to both sides of the corner, respectively, so that the intermediate portion 3 wraps the edge of the corner.

[0053] The adhesive layer 10 may be a double-sided tape, or may be another adhesive layer, for example, an adhesive layer may be painted on the first inner side surface 21 and the second inner side surface 41, and then a protective film may be attached to the adhesive layer.

[0054] In addition, in some embodiments, when the angle between the first inner side surface 21 and the second inner side surface 41 is 180, the adhesive layer 10 (e.g. double-sided tape) can be automatically adhered to the first inner side surface 21 and the second inner side surface 41 by a machine, thereby ensuring the uniformity and consistency of the adhesive layer 10 on the first inner side surface 21 and the second inner side surface 41, which can improve the adhesion quality of the anti-collision strip and prevent the occurrence of adhesive failure or peeling.

[0055] In addition, in some embodiments, the overall outer side surface of the anti-collision strip may be flush, for example, referring to FIG. 6, the first outer side surface 22 of the first side edge mounting portion 2 and the intermediate outer side surface 32 of the intermediate portion 3 may be flush connected, and the second outer side surface 42 of the second side edge mounting portion 4 and the intermediate outer side surface 32 of the intermediate portion 3 may be flush connected.

[0056] In addition, in some embodiments, referring to FIGS. 1, 2 and 3, the junction of the first outer side surface 22 of the first side edge mounting portion 2 and the intermediate outer side surface 32 of the intermediate portion 3 is formed with a first outer side groove 7 extending in the length direction of the anti-collision strip, and the junction of the second outer side surface 42 of the second side edge mounting portion 4 and the intermediate outer side surface 32 of the intermediate portion 3 is formed with a second outer side groove 8 extending in the length direction of the anti-collision strip. Thus, the first outer side groove 7 may form a partition space at the junction of the first outer side surface 22 and the intermediate outer side surface 32, and the second outer side groove 8 may form a partition space at the junction of the second outer side surface 42 and the intermediate outer side surface 32, which reduces the resilience of the anti-collision strip. When the anti-collision strip is in the mounted state, pulling at the junction of the first outer side surface 22 and the intermediate outer side surface 32 is avoided, and pulling at the junction of the second outer side surface 42 and the intermediate outer side surface 32 is avoided, thereby reducing or avoiding peeling of the anti-collision strip due to excessive resilience in the mounted state, particularly in the 90 mounted state.

[0057] In addition, in some embodiments, if the thickness of the anti-collision strip is thick, the first inner side groove 5 and the first outer side groove 7 may be aligned in the thickness direction of the anti-collision strip, and the second inner side groove 6 and the second outer side groove 8 may be aligned in the thickness direction of the anti-collision strip. In addition, in some embodiments, referring to FIGS. 2 and 3, the first inner side groove 5 and the first outer side groove 7 are staggered in the width direction of the anti-collision strip, and the second inner side groove 6 and the second outer side groove 8 are staggered in the width direction of the anti-collision strip, such that the distance between the first outer side groove 7 and the second outer side groove 8 is greater than the distance between the first inner side groove 5 and the second inner side groove 6. Thus, by this staggered arrangement, it is possible to reduce the thickness of the anti-collision strip to some extent, to reduce the resilience of the anti-collision strip, and to improve the adhesion stability of the anti-collision strip.

[0058] In addition, the distance between the groove bottom of the first inner side groove 5 and the groove bottom of the first outer side groove 7 in the thickness direction of the anti-collision strip may have any desired value, for example, in some embodiments, the distance between the groove bottom of the first inner side groove 5 and the groove bottom of the first outer side groove 7 in the thickness direction of the anti-collision strip is greater than 0.5 cm. In some embodiments, the distance between the groove bottom of the first inner side groove 5 and the groove bottom of the first outer side groove 7 in the thickness direction of the anti-collision strip may be 0.8-1.0 cm. Of course, the distance may also have other values less than 0.5 cm, for example 0.4 cm.

[0059] In addition, in the anti-collision strip 1 of the present invention, the first outer side groove 7 and the second outer side groove 8 may have any desired depth, that is, the distance from an opening portion to the bottom of the groove. For example, in some embodiments, the depth of the first outer side groove 7 and the second outer side groove 8 is 0.1 cm-0.3 cm. In some embodiments, the first outer side groove 7 and the second outer side groove 8 have a depth of 0.2 cm. Further, the first outer side groove 7 and the second outer side groove 8 may have the same depth or may have different depths.

[0060] Furthermore, in the anti-collision strip 1 of the present invention, the cross-sectional shapes of the first outer side groove 7 and the second outer side groove 8 may have any desired shapes, for example, in some embodiments, the cross-sectional shapes of the first outer side groove 7 and the second outer side groove 8 include a V-shape (e.g. the V-shape shown in FIGS. 2 and 3), a U-shape, or a semicircular shape. The V-shape. U-shape or semicircular shape not only facilitate processing, but also form an arc-shaped transition at the bottom of the groove, which avoids tearing the anti-collision strip at the first outer side groove 7 and the second outer side groove 8. Of course, the cross-sectional shapes of the first outer side groove 7 and the second outer side groove 8 are not limited thereto, and may be rectangular, trapezoidal, or other shapes.

[0061] In addition, in the anti-collision strip 1 of the present invention, the intermediate portion 3 may have a uniform thickness in the width direction or a variable thickness. Further, in some embodiments, the thickness of the intermediate portion 3 is the same as the thickness of the first side edge mounting portion 2 and the second side edge mounting portion 4. For example, the thickness of the intermediate portion 3 is the same as the thickness of inner side ends of the first side edge mounting portion 2 and the second side edge mounting portion 4 near the intermediate portion 3. In some embodiments, the thickness of the intermediate portion 3 is greater than the thickness of the first side edge mounting portion 2 and the second side edge mounting portion 4. In this way, the intermediate portion 3 provides a reliable and effective protection for the edge of the corner in the adhesive state, regardless how the intermediate portion 3 is tensioned in the width direction of the anti-collision strip. In other embodiments, the thickness of the intermediate portion 3 may also be less than the thickness of at least one of the first side edge mounting portion 2 and the second side edge mounting portion 4. However, as long as the required thickness of the intermediate portion 3 is ensured, the local thickness of the intermediate portion 3 may be prevented from being thin. For example, in some embodiments, the intermediate portion 3 is formed with a plurality of grooves arranged at intervals in the width direction of the anti-collision strip and extending along the length direction of the anti-collision strip, but the thickness of the intermediate portion 3 at the grooves also satisfies the desired thickness.

[0062] Additionally, in some embodiments, the intermediate inner side surface 31 may be planar. In some embodiments, referring to FIGS. 1, 2, and 3, the intermediate inner side surface 31 is a concave arc-shaped surface 9. Thus, the concave arc-shaped surface 9) can accommodate and be attached to the edge when the anti-collision strip 1 is adhered, and the resilience of the anti-collision strip can be reduced.

[0063] In addition, in some embodiments, in order to enhance the protective effect of the concave arc-shaped surface 9 on the edge, the thickness of the intermediate portion 3 at the lowest point of the concave arc-shaped surface 9 is greater than the thickness of the first side edge mounting portion 2 and the second side edge mounting portion 4, for example, greater than the thickness of the inner side ends of the first side edge mounting portion 2 and the second side edge mounting portion 4 near the intermediate portion 3.

[0064] In addition, in the anti-collision strip 1 of the present invention, the width distance between the two side edges of the intermediate inner side surface 31 in the width direction of the anti-collision strip may have any desired value. For example, in some embodiments, the width distance between the two side edges of the intermediate inner side surface 31 in the width direction of the anti-collision strip is between 0.6 cm and 1.2 cm. In some embodiments, the width distance between the two side edges of the intermediate inner side surface 31 in the width direction of the anti-collision strip is between 0.8 cm and 1.0 cm. In addition, the width distance may have other values outside the range of values, such as 0.5 cm, or 1.5 cm.

[0065] Furthermore, in the anti-collision strip 1 of the present invention, in a natural state of the anti-collision strip, the intermediate outer side surface 32 of the intermediate portion 3 is a flat surface or a convex arc-shaped surface. For example. FIGS. 2 and 3 show the intermediate outer side surface 32 being a flat surface. In the mounted state of the anti-collision strip 1, the outer side surface will be tensioned, so that this flat or convex arc-shaped surface ensures an effective protection for the edge by the intermediate part 3.

[0066] In addition, in some embodiments, the first side edge mounting portion 2 and the second side edge mounting portion 4 have a uniform thickness in the width direction of the anti-collision strip. In some embodiments, referring to FIGS. 2 and 3, the first outer side surface 22 of the first side edge mounting portion 2 is obliquely arranged so that the first side edge mounting portion 2 has a gradually decreased thickness, i.e. the first side edge mounting portion 2 gradually decreases, and the second outer side surface 42 of the second side edge mounting portion 4 is obliquely arranged so that the second side edge mounting portion 4 has a gradually decreased thickness, i.e. the thickness of the second side edge mounting portion 4 gradually decreases along a direction from the intermediate portion toward each side edge. In this way, the weight of the anti-collision strip 1 can be effectively reduced and the cost can be reduced while ensuring the protective effect of the intermediate portion 3 for the edge. In addition, the first outer side surface 22 and the second outer side surface 42 may be obliquely arranged flat, or may be obliquely arranged arcuately, or may be obliquely arranged flat and then obliquely arranged arcuately. Of course, the inclined arrangement of first outer side surface 22 and second outer side surface 42 is not limited to this.

[0067] In addition, in the anti-collision strip 1 of the present invention, the widths of the first inner side surface 21 and the second inner side surface 41 may be of any desired value. For example, in some embodiments, the width of the first inner side surface 21 and the second inner side surface 41 is between 2.5 cm and 3.5 cm. Such a width may meet the edge protection requirements of most locations. Additionally, in some embodiments, the width of the first inner side surface 21 and the second inner side surface 41 is between 2.8 cm and 3.0 cm. In addition, the width may have other values outside the range of values, such as 2.0 cm to 2.4 cm, or 3.6 cm to 3.8 cm.

[0068] Further, considering the different corner protection requirements, in some embodiments, at least one of the first side edge mounting portion 2 and the second side edge mounting portion 4 is formed with at least one cutting track (not shown in figures) extending along the length of the anti-collision strip, the cutting track is configured to allow a user to cut along the length of the anti-collision strip to reduce the width of the corresponding side edge mounting portion. In this way, if necessary, the user can adjust the width of at least one of the first side edge mounting part 2 and the second side edge mounting part 4 according to the width of the side of the corner, so that at least one of the first side edge mounting part 2 and the second side edge mounting part 4 is more adapted to the corresponding side, thereby enhancing the user's feeling of use.

[0069] In addition, the cutting trace may be an indicating mark or may be an indicating recess. In addition, the cutting trace may be formed on the outer side surface of at least one of the first side edge mounting portion 2 and the second side edge mounting portion 4, or may be formed on the outer side surface and the inner side surface of at least one of the first side edge mounting portion 2 and the second side edge mounting portion 4.
