Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

A stair edge closing structure is shown in figures 1-3 and is used for connecting two pedals 1 laid on the surface of a stair, and comprises two supporting sections 2 provided with clamping grooves 21 and a transition section 3 which is used for connecting the two supporting sections 2 and enabling the two supporting sections 2 to be perpendicular to each other, wherein the pedals 1 can be inserted into the clamping grooves 21. The supporting section 2 further comprises a bottom plate 22, a first supporting plate 23 and a second supporting plate 24 which are connected with each other through the bottom plate 22, and a clamping groove 21 is formed among the bottom plate 22, the first supporting plate 23 and the second supporting plate 24; the transition section 3 comprises a first transition section 31 connected with the first support plate 23 and a second transition section 32 connected with the second support plate 24, and a buffer cavity 4 is formed among the first transition section 31, the second transition section 32 and the bottom plates 22 of the two support sections 2.

In the embodiment, the stair edge closing structure is manufactured by adopting an aluminum alloy extrusion forming technology, the aluminum alloy blank placed in the die cavity is forced to generate directional plastic deformation by applying forced pressure, and the directional plastic deformation is extruded from the die hole of the extrusion die, so that the support section 2 and the transition section 3 are integrally formed, and the stair edge closing structure has better strength and toughness.

Because the corners of the stair step surface comprise the external corners protruding outwards and the internal corners recessed inwards, different edge closing structures are often used for connecting the pedals at the external corners and the internal corners. In order to improve the universality of the stair edge closing structure, so that the stair edge closing structure can be simultaneously suitable for an external corner and an internal corner, and can reduce the number of die sinking in the processing process and reduce the production cost, as shown in fig. 2, in the embodiment, two supporting sections 2 are respectively connected with two ends of a transition section 3 through design and are in smooth transition, so that the stair edge closing structure is in an L shape, wherein a first transition section 31 is in an arc shape, and a second transition section 32 is in a right-angle shape, when the stair edge closing structure is connected with two pedals 1 positioned at the external corner, the right-angle second transition section 32 can be directly buckled at the corner of the step surface and is attached to the step surface of the stair, and at the moment, the first transition section 31 is positioned above the second transition section 32, so that the corner is in the arc shape, and collision caused by the fact that the corner is too sharp is avoided; when the stair edge closing structure is connected with the two pedals 1 positioned at the internal corner, the stair edge closing structure can be rotated by 180 degrees for use, the second transition section 32 is positioned above the first transition section 31, and a triangular cavity can be formed between the arc-shaped first transition section 31 and the two step surfaces, so that smooth transition is realized, and the corner is prevented from cracking due to stress concentration.

Present interior decoration adopts the mode of direct spraying foaming adhesive on stair step face to lay stair tread more, when stair step face local exists sunken, the unevenness, need handle with gasket etc. still need exert pressure in order to guarantee foaming adhesive and footboard 1 full contact after laying, complex operation, and fitment effect uniformity is poor, and the viscose is difficult to the clearance when follow-up maintenance or change footboard 1. In the embodiment, the stair edge-closing structure is arranged at the corner of the stair to realize the plug-in connection of the pedal 1, so that the problems that the adhesive is not uniformly coated and is difficult to clean and the like in the adhesive connection process are solved. When the stair is installed, firstly, the stair edge folding structure is fixedly installed at each internal corner of the stair through screws, then the pedals 1 are sequentially inserted into the clamping grooves 21 at the internal corners, so that the side edges of the pedals 1 at the internal corners are fixed, after the pedals 1 are paved on each stair surface of the stair, the side edges of two adjacent pedals 1 at the external corners are sequentially inserted into the clamping grooves 21 of the stair edge folding structure at the external corners, so that the second supporting plates 24 of the stair edge folding structure at the external corners are attached to the stair surface, and the installation is completed. When the stair step surface is uneven, the cavity can be adjusted to accommodate the bulge or the recess of the stair step surface, and the flatness of the installation of the stair step surface is ensured; simultaneously, this hole 5 can play and fall make an uproar, dampproofing function, and when the people trampled on footboard 1, hole 5 provides the space that the bending kick-backed for footboard 1, and the sense of touch is softer, comfortable when can making trample.

In this embodiment, during installation, the stair edge closing structure located at the internal corner is fixedly connected to the stair body through screws, and the stair edge closing structure located at the external corner is connected with the pedal 1 through the clamping groove 21 in an inserting mode, so that the pedal 1 cannot be damaged during installation, and the stair edge closing structure is convenient to disassemble. Wherein, the length of the first supporting plate 23 is greater than that of the second supporting plate 24, so that when the first supporting plate 23 of the stair edging structure of the utility model located at the internal corner is fixed by screws, the second supporting plate 24 does not interfere with the first supporting plate 23; meanwhile, when the two pedals 1 positioned at the external corners are connected, the first supporting plate 23 is longer and has better toughness, so that the first supporting plate 23 can be properly bent, the pedals 1 can be conveniently inserted, and the installation is convenient.

In order to increase the friction force on the surface of the stairs and prevent slipping during descending the stairs, in the present invention, the surface of the first supporting plate 23 is provided with a plurality of anti-slip strips 231.

In order to avoid the sharp edge of the stair edging structure and the scratch during installation, the end of the first support plate 23 is provided with a round angle.

In order to avoid the gap between the second support plate 24 of the stair edging structure at the internal corner and the surface of the tread 1, which causes dirt to be contained and accumulated, in the utility model, the end part of the second support plate 24 is provided with a slope 241, so that the lower surface of the second support plate 24 is abutted against the tread 1, and the slope 241 forms a slope with the surface of the tread 1, thereby being easier to clean and clean.
