Description

Angle control structure for railing for stairs {ANGLE CONTROL STRUCTURE FOR CROSSBAR OF HANDRAIL}

The present invention relates to a structure for adjusting the angle of a column for a stair railing, and in particular, by increasing the allowable range of the angle of the cross column with respect to the vertical column while allowing the cross column to be easily coupled to the vertical column of the railing with a staircase. In addition to ensuring that the angle can be adjusted smoothly, the structure of the stair railing struts with an improved structure to connect the ends of the transverse struts to the outside of the vertical struts without additional bolting work and to be rotatably coupled to the vertical struts. It relates to an angle adjustment structure.

In general, the existing railing is used by connecting a crossbar between the strut and the strut, but the crossbar is formed as an upper crossbar and a lower crossbar, and a plurality of balusters (vertical bars) are combined in a vertical direction between the upper and lower crossbars. It is common.

In the case of the railing combined as described above, a base plate is formed at the lower part of the post and the post, and the base plate is first fixed to the ground to prevent the post from moving. In the process of combining the pillars with the two pillars, the railing is correctly installed only if the distance between the pillars and the length of the crossbar are the same.

In the case of installing a railing as above, the length of the crossbar to be assembled according to the distance between the pre-installed strut and the strut must be accurately cut, and the length of the crossbar is extended compared to the distance between the strut and the strut. There is no particular problem by cutting and assembling the crossbar. However, if the length of the crossbar is short, the bolt that is bolted between the strut and the strut is exposed to the outside, which is not good in terms of aesthetics. Problems such as shortening the life of the product have been raised.

As a prior art related to the existing handrail connection structure, as disclosed in Korean Registered Utility Model Publication No. 0132118 "Handrail Connection Device for Building Stairs" (Registration Date: September 23, 1998), it is possible to connect the support rod of the fence forming the handrail of the stairs. To ensure that the upper end of the support rod installed at both ends of the fence and the connector formed by a hinge part separated on both sides so that the inclination can be freely adjusted according to the inclination angle formed by the fence support rod at a certain height, the lower end of the support rod is connected to the floor of the site. It is configured to be able to fix and install a fixing piece having a connection insertion portion with a screw so that it can be fixedly installed on the fixing piece, and a bolt hole is formed in the connection insertion portion of the fixing piece to fix the U-shaped hook with a nut.

As other prior art related to the existing handrail connection structure, Korean Laid-Open Patent Publication No. 10-2011-100835 "Handrail and copper column connector of stair railing and assembly and connection method of handrail and copper column using the same" (Publication date: 2011.09 15), as a connection mechanism for connecting the handrail of the stair handrail and the copper column, and has an external size that can be inserted into the coupling hole drilled in the handrail, and the end of the copper column is on one side. A connector body having a pillar insertion port opened to be inserted and fixed, and a copper column receiving space corresponding to the outer circumferential shape of the copper column; By elastically connected to the side of the connector body, it protrudes from the outer circumferential surface of the connector body when no force is applied, and is pushed into the interior of the connector body when external force is applied. A resilient fixing unit provided so as to be recovered to; And a pressing flange formed to protrude from the outer circumferential surface of the connector body to the outside of the side, and provided to be hooked around the coupling hole when the connector body is inserted into the coupling hole of the handrail.

In this case, the elastic fixing part and the pressing flange are used to be elastically coupled to the rim of the coupling hole, but the gap between the elastic fixing part and the pressing flange is caused to flow according to the size of the coupling hole thickness of the handrail. There is a fear that the main body may not be able to be connected to the handrail's joint hole.

In addition, when a large load is transmitted to the elastic fixing unit, there is a risk of being easily damaged, and in the process of fitting the rim of the bonding hole into the gap between the elastic fixing unit and the pressing flange, the operator can properly It is not possible to easily identify whether it has been joined, and for this reason, even if the rim of the coupling hole is not flexibly fixed in the gap between the elastic fixing unit and the pressing flange, the operator may be mistaken, and accordingly, the baluster can easily be removed from the crossbar. There is a risk of safety accidents as they leave.

As another prior art related to the existing stair railing posts, as disclosed in Korean Laid-Open Patent Publication No. 10-2015-0031511, "Stand angle adjustment device for stair railings" (published date: 2015.03.25), consisting of a pair of pluralities. A plate-shaped vertical column having four through holes; Horizontal posts joined between each vertical post; An upper fixing unit detachably coupled to the upper portion of each vertical column; A lower fixture that is detachably coupled to the lower portion of each of the vertical posts as well as coupled to the upper surface of the stairs; Fastening plates having bolt fastening holes installed on both sides of each vertical column; Support having a post insertion hole through which the horizontal post is inserted so as to adjust the angle of the horizontal post with the pivot installed between each vertical post, and an inserting hole through which the end of the bolt fastened to the fastening plate is inserted and fastened. Since it is composed of a rotating ball member provided with a protrusion; it has the advantage of being able to adjust the horizontal post at various angles around the vertical post while combining the vertical post and the horizontal post of the stair railing. In order to be able to rotate, it is cumbersome to fasten the bolt to the inserting hole of the rotating ball member through the bolt fastening hole of the fastening plate, and there is a disadvantage that the fastening plate is exposed to the outside of the vertical column, which is not beautiful in appearance.

In addition, since the angle adjustment in the process of combining the existing horizontal posts with the vertical posts is limited to the size of the inner diameter in the height direction of the post insertion hole, the angle adjustment range of the horizontal posts with respect to the vertical posts is small. There is a fear that it may not be suitable.

The connection hole 114 is formed to be larger than the outer diameter of the pivoting protrusion 127, thereby supporting the rotational movement of the pivoting member 120 in the entry hole 112.

In addition, the connector body 110 is formed in an oval shape having a vertical width in the height direction greater than that in the horizontal direction, and the entry hole 112 has a width in the height direction that is longer than the width in the horizontal direction. desirable.

Accordingly, as the connector body 110 is formed in an elliptical structure having a longer width in the height direction than in the horizontal direction, the rotation member 120 can be rotated in the entry hole 112 in the height direction, so that the rotation member ( The range of rotation angle of 120) can be increased.

In addition, the connector body 110 of the connector 100 is coupled by a locking means 200 formed on the other side after one side passes through the coupling hole 12 and enters the inside of the hollow 15 of the vertical column 10 It is locked and coupled to the rim of the ball 12.

At this time, the elastic protrusion 220 is retracted to the inside where the distance between the connector body 110 is narrowed while passing through the coupling hole 12, and then returns to the outside after passing through the coupling hole 12. While being in contact with the inside of the rim of the coupling hole 12 is supported.

As shown in FIG. 3, the elastic protrusion 220 is bent by a slot groove 230 formed to be horizontally spaced apart from each other in the front and rear sides of the connector body 110 (contraction and return in the front and rear directions). Operation) becomes possible.

After the connector 100 is coupled to the coupling hole 12 of the vertical column 10, the angle of the transverse column 20 with respect to the vertical column 10 can be adjusted to an inclined angle.

The angle adjustment of the transverse post 20 is a rotation member 120 based on the rotation protrusion 127 accommodated in the connection hole 114 and the connector body 110 is fixed to the coupling hole 12 of the vertical post 10 Since it can be rotated, it is possible to adjust the angle of the transverse column 20 coupled to the rotation member 120.

In addition, the pivoting protrusion 127 is supported so as to enable an elevating operation within the connection hole 114 in the vertical direction, and the rotation member 120 accordingly is within the entry hole 112 of the connector body 110 It becomes possible to rotate based on the pivoting protrusion 127 in the up and down height directions.

Accordingly, due to the structural characteristics of the connector body 110 and the entry hole 112 having an elliptical structure, the rotation angle of the transverse column 20 has the advantage of having a larger rotation angle than that of the circular structure.

Therefore, in the present invention, the connector body 110 is accommodated in the hollow 15 of the vertical post 10, and the pivoting protrusion 127 and the connecting hole 114 for rotating the pivot member 120 from the connector body 110 Since it is not exposed to the outside, it is not only possible to give aesthetic appearance, but also it is possible to easily couple the transverse post 20 to the vertical post 10 by using the locking means 200, so that the transverse post to which the connector 100 is combined It is possible to improve the convenience of work because it does not require a bolt fastening operation for rotating the (20) to the vertical column (10).

In addition, the present invention has a circular structure in which the rotational angle range of the transverse column 20 coupled with the rotating member 120 due to the structure in which the width in the height direction of the connector body 110 and the entry hole 112 is larger than the width in the horizontal direction It has an advantage that can be further increased.
