DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereafter, the present disclosure is described in detail with reference to the accompanying drawings.

[0015] The terms and words used in the present specification and claims should not be interpreted as being limited to typical meanings or dictionary definitions, but should be interpreted as having meanings and concepts relevant to the technical scope of the present disclosure based on the rule according to which an inventor can appropriately define the concept of the terms to describe most appropriately in the best possible way that he or she knows for carrying out the disclosure.

[0016] Accordingly, it should be appreciated that there may be various equivalents and modifications that can replace the embodiments and the configurations at the time at which the present application is filed.

[0017] The present disclosure relates to a bollard for floor installation that include: a base 10 that is installed on the ground; an intermediate outer cylinder 40 that is installed on the top of the base; a connector 20 that is fitted in the base through the internal space of the intermediate outer cylinder; a spring 30 that is fitted on the connector; and an extension outer container 50 that extends a length by being coupled to the intermediate outer cylinder 50.

[0018] In more detail, the base 10 has: a grounding fixing portion 11 that can be installed and fixed on the ground by a fixing member (not shown); and an upright fixing portion 12 that protrudes upward from the top of the ground fixing portion and has an insertion fastening groove 12a.

[0019] Further, the connector 20 has: an insertion fastening portion 21 that is formed at the lower portion thereof to be fitted in the insertion fastening portion of the base; and a main body 22 that is integrally formed on the top of the insertion fastening portion.

[0020] Further, the main body may be formed in a cylindrical shape, as shown in FIG. 2, or an upper ellipsoidal solid 22a and a lower ellipsoidal solid 22b that are different in outer diameter may be combined while forming a coupling groove 22c, as shown in FIG. 3. In more detail, the upper ellipsoidal solid and the lower ellipsoidal solid are combined with each other and the coupling groove 22c is formed by the difference in outer diameter, whereby an 8 shape is formed. The lower ellipsoidal solid is not limited to an ellipsoidal solid shape.

[0021] Further, the intermediate outer cylinder 40 has: an internal space 41 that is defined therein; a locking supporting plate 43 that protrudes inward perpendicular to the longitudinal direction from the inner wall of the lower end of the intermediate outer cylinder; a spring locking hook 44 that protrudes upward from the end of the locking supporting plate; and a compressive separating portion 45 that is formed at the upper end in the internal space of the intermediate outer cylinder.

[0022] Further, the compressive separating portion 45 may be formed in a plate shape to be able to define the internal space, as shown in FIG. 2, or, as shown in FIG. 3, may have: a semispherical separation socket 45b at the center thereof; and a compressive separation plate 45a formed between the edge of the semispherical separation socket 45b and the inner wall of the intermediate outer cylinder.

[0023] Further, the extension outer cylinder 50 has a second coupling portion 51 formed at the lower end thereof to be able to be coupled to the first coupling portion 42 of the intermediate outer cylinder.

[0024] As an embodiment, the grounding fixing portion 11 of the base 10 is fixed to the ground using a fixing member (not shown) and then the insertion fastening portion 21 of the connector 20 can be inserted and fastened into the insertion fastening groove 12a of the upright fixing portion 12 of the base through the internal space 41 of the intermediate outer cylinder 40. Then, the spring 30 is installed outside the main body 22 of the connector 20, the lower end of the spring is fixed by the spring locking hook 44 of the intermediate outer container, and the upper end of the spring is fixed by the compressive separating portion 45. Accordingly, it is possible to prevent the spring from separating out of the internal space 41 of the intermediate outer container. The main body of the connector may be formed in a cylindrical shape, as in FIG. 2, or may be manufactured in an 8 shape. When the main body is formed in a cylindrical shape, the compressive separating portion 45 of the intermediate outer cylinder is formed over the internal space and may be formed in a disc shape along the inner side of the intermediate outer cylinder.

[0025] When it is the main body is formed in an 8 shape, the compressive separating portion may be composed of the semispherical separation socket 45b at the center thereof and the compressive separation plate 45a to be able to define the internal space between the semispherical separation socket and the inner wall of the intermediate outer cylinder, and the upper ellipsoidal solid 22a of the connector is inserted in the semispherical separation socket and operates like a hip joint when an external force is applied.

[0026] Further, the spring locking hook 44 protruding upward from the end of the locking supporting plate 43 of the intermediate outer cylinder can fix the lower end of the spring in cooperation with the locking supporting plate.

[0027] Further, since the first coupling portion 42 is formed at the upper end of the intermediate outer cylinder 40 and the second coupling portion 51 is formed at the lower end of the extension outer cylinder 50, it is possible to extend the height by coupling the extension outer cylinder 50 to the intermediate outer cylinder.

[0028] When an external force is applied to the intermediate outer cylinder 40 or the extension outer cylinder 50 from the left, the bollard may incline, as shown in FIG. 1. In this case, when the connector is formed in a cylindrical shape, as shown in FIG. 6, the left lower end of the spring is compressed upward by the spring supporting plate and the spring locking hook of the intermediate outer cylinder and simultaneously the right upper end of the spring is compressed downward by the compressive separating portion at the upper portion of the intermediate outer cylinder, whereby it is possible to attenuate and absorb impact, and when the external force is removed, bollard is returned by the elasticity of the spring.

[0029] Further, when the main body is formed in an 8 shape, as shown in FIG. 7, and when an external force is applied from the right, the right lower end of the spring is compressed upward by the spring supporting plate and the spring locking hook of the intermediate outer cylinder and simultaneously the left upper end of spring is compressed downward by the compressive separating portion at the upper portion of the intermediate outer cylinder, whereby it is possible to attenuate and absorb impact. Further, since the upper ellipsoidal solid is inserted in the semispherical separation socket and operates like a hip joint, it is possible to secure a firm operation of the intermediate outer cylinder when an external force is applied, and the bollard is returned by the elasticity of the spring when the external force is removed.

[0030] Further, when the main body is formed in an 8 shape, the upper ellipsoidal solid and the lower ellipsoidal solid can be flexibly deformed around the coupling groove 22 when an external force is applied, so it is possible to more effectively absorb and attenuate impact.

Therefore, the present disclosure is not limited to the embodiments.
