Description

Technology Field

[0001] The present invention relates to a handrail connector, and more specifically, to a handrail connector in which the connecting portion is formed in a spherical shape to facilitate angle adjustment. Background Technology

[0003] Since stairs pose a high risk of falling accidents, a design fence is installed as a safety device to ensure the safety of stair users. The design fence consists of posts fixed vertically at regular intervals and a railing that serves as a fence by connecting the upper or middle sections of adjacent posts. The railing installed on the stairs is installed at an angle equal to the slope of the stairs, while the railing installed on landings, rooftops, terraces, etc., is installed horizontally with respect to the floor. As for the method of fixing the posts and railings together, in the case of steel, welding or a separate fastening member is used.

[0004] Recently, with the increase in outdoor activities such as hiking, trekking, and walking trails, and the social boom in nature-friendly environments, wooden (deck) stairs and designer fences are being installed in hiking trails, walking paths, and ecological parks. Designer fences installed on building stairs, rooftops, or terraces are generally made of steel. Since building stairs have a constant slope but rooftops and terraces have flat surfaces, the fastening members that securely connect the posts and railings are classified into sloped and horizontal types, and even within the sloped type, there are various types produced depending on the angle of incline.

[0005] However, since design fences installed outdoors, such as hiking trails or ecological parks, do not have a uniform slope and are mostly made of wood, which is an eco-friendly material, the posts and railings cannot be fixedly joined by welding, so separate fastening members are used. For example, as shown in FIG. 1a, for a design fence installed in a straight line on a horizontal surface, the integrated fastening member (3) for fixing the posts (1) and railings (2) can have the same shape. However, as shown in FIG. 1b, for a design fence installed on a sloped surface, the slope of the railing varies depending on the stairs, so the fastening member for fixing the vertically installed posts (1) and railings (2) must have a different installation angle for each post. Therefore, as used in a design fence installed in a straight line on a horizontal surface (Fig. 1a), it is not possible to use the same fastening member for all of them. Thus, for a design fence installed on a sloped surface, it is common to fix the railings (2) to the posts (1) using bolts and nuts (4).

[0006] In a structure like the one above, there is a problem in that it is difficult to fix each post and railing of the fence and to deform it at various angles.

[0007] To solve this problem, Patent Document 01 (Registered Patent Publication No. 10-1054261, Post and Handrail Fastening Member of a Design-Type Fence with Easy Angle Adjustment) comprises: a plate-shaped post-side fastening member fixedly coupled to the post, having a first through hole formed in the central part; a first hinge piece formed such that a first pivot penetrates the first through hole and protrudes to the front of the post-side fastening member while a first flange portion formed at one end engages with the rear surface of the post-side fastening member; and a handrail-side fastening member fixedly coupled to the handrail, manufactured as a plate-shaped member, having a cuboid shape with one side open, and having a second through hole formed in the central part of the surface corresponding to the open surface. A configuration is disclosed in which the first and second pivots are combined and fastened by including a second hinge piece formed such that the second flange portion engages with the railing-side fastener and the second pivot penetrates the second through hole and protrudes toward the front of the railing-side fastener.

[0008] However, according to Patent Document 01, a hinge piece is required separately, so the structure is not only complex but the range of motion is also limited. Prior art literature

[0030] It is understood that various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the claims of the present invention, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.

[0031] The scope of protection sought through this specification is defined by the claims set forth below rather than by the detailed description above, and should be interpreted to include all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents.

[0033] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

[0034] FIG. 2 briefly illustrates an example in which a railing connector (100) according to an embodiment of the present invention is connected, FIG. 3 shows an exploded view of a railing connector according to an embodiment of the present invention, and FIG. 4 shows a cross-sectional view of a railing connector according to an embodiment of the present invention.

[0035] A railing connector (100) according to an embodiment of the present invention comprises: a support portion (11) that is fastened to one side of a support post (1); a neck portion (12) that is integrally extended and protruded from the support portion; a support connecting portion (10) that is integrally extended from the neck portion and protruded in a spherical shape and has a head portion (13); a rotating connecting portion (21) that is formed with a spherical receiving portion to receive and rotatably connect the head portion (13); and a crossbar connecting portion (20) that is integrally extended from the rotating connecting portion and wraps around one end of a crossbar (2).

[0036] The above-mentioned support connecting part (10) has a through hole formed therein, and a reinforcing rod (14) is integrally inserted into the through hole. The above-mentioned pivot connecting part (21) is connected so as not to slip past the center of the head part (13), but is connected so as not to pass through the middle of the neck part (12) and the head part (13), thereby allowing the rotation range to be widened.

[0037] The receiving portion (211) in which the head portion (13) is received has an inner surface formed to be identical to the size and curvature of the head portion (13) in correspondence with the size of the head portion (13), so as to be able to receive the head portion (13).

[0038] When the receiving portion (211) receives the head portion (13), it is received in the pivoting connecting portion (21) to expand the range of motion, but the head portion (211) is received only to the extent that it is not completely received in the receiving portion (211) and does not fall out. In order for the head portion not to fall out, it must be received by passing through the central part of the head portion. As illustrated, the end of the pivoting connecting portion (21) is coupled to be located between the central part of the head portion (13) and the neck portion (12). Preferably, the head portion is received such that the end of the pivoting connecting portion (21) passes slightly past the central part and is located at the 1 / 3 point between the center of the head portion and the neck portion.

[0039] If the head is accepted too deeply, the range of rotation may be limited, and if it is accepted too shallowly, there is a risk that the head may slip out, so it is desirable to accept it up to about one-third of the way. The one-third mark is the position where the end is closer to the center, starting from the center of the head.

[0040] In order to increase the range of motion of the fixed cap (22), it is preferable to form the neck portion (12) thin and the head portion (13) as large as possible. However, if the neck portion becomes thin, problems such as breaking may occur when an external impact is applied. In this embodiment, to solve this problem, a reinforcing rod (14) is inserted to reinforce the strength of the neck portion (12).

[0041] The above reinforcing rod (14) can be formed integrally by screw connection or rivet connection, or the initial molding process can be integrally insert molded.

[0042] Additionally, it is preferable for the head portion (14) to be formed in a large spherical shape, but as the head portion (14) becomes larger, there is a problem that the cooling time during mold manufacturing becomes longer. In this embodiment, to solve this problem, a long groove-shaped slit (141) can be formed in the head portion (14). The handrail connector according to the embodiment of the present invention is manufactured by placing it in a mold. At this time, if a slit-shaped groove is formed in the head portion (14), the cooling time can be shortened.

[0043] The end of the head portion (13) is formed flat so that a predetermined space is formed between the receiving portion (211) and the end.

[0044] The above crossbar connecting part (20) has a through hole formed therein, and a pressure rod (23) is inserted into the through hole to press the head part (13) and fix the head part.

[0045] The fixed cap (22) has a predetermined thickness in the portion connected to the pivot connecting portion (21) and includes a first region (221) with screw threads and a second region (222) with a space formed therein, and a polygonal screw head is formed on the pressure rod (23) located in the second region (222) so that the pressure rod (23) can be tightened.

[0046] When installing the crossbar (2), the crossbar connecting part (20) is positioned in the desired direction and fixed to the support post (1), but once the installation of the crossbar is complete, there is no need for the crossbar to move further. Rather, if the crossbar connecting part (20) moves repeatedly, its durability may decrease. Therefore, by using a pressure rod (23) to press the flat end of the head part (13), the frictional force between the head part (13) and the inner surface of the receiving part (211) of the pivot connecting part (21) is increased, so that it can be firmly fixed without moving even when an external force is applied.

[0047] At this time, an opening (223) may be formed on one side of the second area (222) to allow a screw head mechanism to be fastened so that the pressure rod (23) can be tightened. Since a space is formed in the second area (222), a space is secured to tighten the pressure rod (23), and if an opening (223) is formed in the area where the screw head of the pressure rod (23) is located, a mechanism such as a wrench can be inserted through the opening (223) to rotate the screw head.

[0048] The above fixing cap (22) is in the form of two separate parts, and a connecting screw hole (224) for joining the fixing cap and a fixing screw hole (225) for fixing the crossbar are formed. After joining the separated fixing caps through the connecting screw hole, the crossbar can be inserted into the space of the fixing cap, and then the crossbar can be fixed by fastening a screw through the fixing screw hole (225).

[0050] As seen above, the spherical head portion (13) is not fully inserted into the pivoting connection portion (21), but is inserted only enough so that the pivoting connection portion (21) does not come out, thereby maximizing the range of rotation. Therefore, a crossbar can be installed in the desired direction even in places with sharp turns, such as walking paths.

[0051] In addition, after installing the railing, the head portion (13) can be pressed using a pressure rod (23) to increase friction between the head portion (13) and the inner surface of the receiving portion (211), thereby allowing it to be firmly fixed so as not to shake even under external force.

[0053] The scope of protection sought through this specification is defined by the claims set forth below rather than by the detailed description above, and should be interpreted to include all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents.
