In addition, the proposed mounting bracket assembly is simple in structure yet more versatile. (Dependent Claim: 4, Drawing: 6)

Description

[Technical Field]

[0001] The present invention relates to a fixture for use in construction and the home, and in particular to a fixture that can be used to secure stair treads and at the same time allows the angle of inclination of the tread relative to the horizontal to be adjusted. [Background technology]

[0002] The prior art discloses various design solutions for attaching stair treads to frames (see, for example, Patent Document 1 published on October 12, 2016, Patent Document 2 published on November 13, 2018, and Patent Document 3 published on July 13, 2016). These technical solutions allow the inclination angle of the stair treads to be adjusted relative to the horizontal. However, these technical solutions have common drawbacks, such as complex design, a small adjustment range for the inclination angle of the stair treads, and insufficient reliability for fixing the stair treads in the required position.

[0003] The prior art also discloses a mounting bracket assembly as part of a stair frame mounting mechanism (see Patent Document 4, published September 30, 2021). This mounting bracket includes a bearing support and a pivot support connected to each other, each consisting of a base and a side wall. The side wall of the pivot support has an arc-shaped slot, and the bearing support and the pivot support are connected to each other by bolting using through holes provided in the side wall and the arc-shaped slot. The angle formed by the end of the arc-shaped slot and the axis passing through the center of the through hole in the side wall of the pivot support is in the range of 55 to 65 degrees. Fixation in place is achieved by tightening the bolt in the arc-shaped slot. This technical solution has been adopted as a prototype.

[0004] The drawbacks of this prototype are the insufficient range of adjustment for the angle of the stair treads and the insufficient reliability for fixing the stair treads in the required position. [Prior art documents] [Patent documents]

[0006] The technical object of the present invention is to overcome the drawbacks of the prior art.

[0007] By addressing these technical objectives, the present invention achieves the technical effects of expanding the scope of application of means for allowing a wide range of adjustment of the angle of a stair tread, and enabling the stair tread to be fixed sufficiently and securely at a desired position. In addition, the proposed mounting bracket assembly is simple in structure yet more versatile. [Means for solving the problem]

[0008] The present invention provides a mounting bracket assembly comprising a mounting support and a pivoting support, each of which comprises a base and a sidewall perpendicular to the base, the bases of the mounting support and the pivoting support having at least one mounting hole, the sidewall of the pivoting support having an arc-shaped through-slot, the sidewalls of the mounting support and the pivoting support being connected to each other by two fasteners, one of which serves as a rotation axis for the mounting support and the pivoting support and the other of which is fixed to the sidewall of the mounting support and slides along the arc-shaped through-slot of the pivoting support, the arc-shaped through-slot having a length such that the base planes of the mounting support and the pivoting support can be positioned at an angle ranging from 25 degrees to 90 degrees, and one of the sidewalls of the mounting support and the pivoting support having an additional through-slot.

[0009] The fasteners may be bolted, screwed, riveted, studs, pins or combinations thereof.

[0010] Additional through holes are formed in the side wall of one of the mounting and pivoting supports, and corresponding holes are drilled in the side wall of the other support to allow for placement of additional fasteners in these holes.

[0011] The additional fasteners may be bolted, screwed, riveted, studs, or pins.

[0012] In addition, an additional through hole can be formed in the side wall of one of the mounting support and the rotating support, allowing a self-tapping screw to be screwed into the side wall of the other support through the through hole. [Brief explanation of the drawings]

[0015] The present invention provides a mounting bracket assembly comprising a mounting support 1 and a pivoting support 2. Each support 1 and 2 comprises a base 3 and a side wall 4 perpendicular thereto.

[0016] The bases 3 of the supports 1 and 2 each include at least one mounting hole 5. There may be multiple mounting holes, such as two, three, four, five, or more. The mounting holes 5 may have different shapes, such as circular, square, rectangular, oval, or other shapes, and may be arranged in the same or different lines, rows, or otherwise in the plane of the base 3.

[0017] The side wall 4 of the pivot support 2 is formed with an arc-shaped through slot 6 .

[0018] The mounting support 1 and the pivoting support 2 are connected by their side walls 4 by two fasteners 7 and 8, one of which (7) is fixed in a hole 10 in the supports 1 and 2 and serves as their axis of rotation relative to each other, and the other (8) is fixed to the side wall 4 of the mounting support 1 so as to slide along the arc-shaped slot 6 in the pivoting support 2. In the context of the present invention, the fasteners 7 and 8 may be bolted fasteners, screw fasteners, threaded fasteners, studs, pins or combinations thereof, for example, the fastener 7 may be a screw fastener and the element 8 a pin, or any other possible combination thereof.

[0019] The arc-shaped through slot 6 is formed to a length that allows it to be positioned at an angle between 25 and 90 degrees relative to the plane of the base 3 of the supports 1 and 2. Such a length of the through slot 6 ensures a wide range of adjustment for the stair tread angle that is ensured on the plane of the base 3 of the pivoting support 2. An angle of less than 25 degrees is impractical because the angle relative to the horizontal is small, while an angle of more than 90 degrees is impractical because the stringer to which the mounting support is fixed may tip over.

[0020] The side wall 4 of one of the supports (1 or 2) is further provided with a through-hole 9. During installation, this hole in one of the supports ensures sufficient reliability for fixing the stair tread in the required position. This is achieved as follows: if the plane angle of the bases 3 of supports 1 and 2 is not at an end position, supports 1 and 2 require additional fixing relative to each other. In this case, after setting the desired angle using the through-hole 9 formed in one of the side walls 4 of supports 1 or 2, corresponding holes are drilled in the side wall 4 of the other support 2 or 1, respectively, and additional fasteners are placed in these holes. Bolted fasteners, screw fasteners, studs, pins, etc. can be used as additional fasteners. The supports can be made of any material that provides the required properties, such as steel, aluminum, or other alloys.

[0021] The following are non-limiting examples of using the present invention.

[0022] The load-bearing frame of the staircase includes at least two mounting brackets arranged in pairs, symmetrically with respect to each other, each mounting bracket including a load support and a pivot support connected to each other, each support having a base and a side wall, and configured to pivot about the horizontal axis of the bracket.

[0023] The base of the pivot support of the mounting bracket was provided with an eye of at least 20 + 2 mm in length directed away from the stringer and was attached to the load-bearing frame using a bolted connection.

[0024] The through-holes in the side walls of the load support were secured coaxially to the arc-shaped through-slots in the pivot support when the brackets were attached using bolts, screws, lock washers, and flat washers. The load support and pivot support were further connected by fasteners passing through the respective through-holes. In one embodiment, additional through-holes in the pivot support were drilled through the additional through-holes in the load support using self-tapping screws during the stair installation process. In another embodiment, additional through-holes in the pivot support were drilled through the holes in the load support, and split pins were securely inserted into these through-holes. The through-holes in the side walls of the load support were fastened coaxially to the through-holes in the pivot support with bolts and nuts, forming a pivot axis for the two supports to rotate relative to each other.

[0025] A pivoting support with a height of 84 + 2 mm and C-shaped side walls was used, and the base of the tread was placed parallel to the horizontal on stairs with different inclination angles from 25 to 90 degrees.

[0026] The tread mounting brackets were attached to the load-bearing frame using quick-mount bolts and nuts. After aligning the bolts, they were tightened to a force of 40N, allowing each stair tread to support a maximum recommended lateral load of 2,000-3,000N at the mounting point.

[0027] Such a design of the mounting bracket assembly overcomes the drawbacks of the prior art, allows for a wide range of adjustment of the stair tread angle, and expands the range of tools that can be used to securely fix the stair tread in the required position (additional fixing points for the required position). Also, the proposed mounting bracket assembly is simple in structure yet more versatile.

[0028] A search conducted through publicly available sources confirms that all of the combinations of features of the present invention are neither known nor explicitly suggested in the prior art, and therefore the present invention satisfies the patentability requirements of "novelty" and "inventive step."

[0029] The present invention is composed of materials and elements that are standard in the art and are interconnected in a specific way, making it industrially applicable, and therefore the invention also satisfies the patent requirement of "industrial applicability."

[0030] It is readily understood that other changes, modifications, and embodiments will become apparent to those skilled in the art after considering the description and embodiments of the present invention, and therefore all such changes, modifications, and embodiments, as well as other fields of application that do not contradict the essence of the present invention, should be construed as falling within the scope of protection granted by the appended claims of the present invention.
