Elastic bollards for rack protection

Abstract

To provide an elastic bollard for rack protection.SOLUTION: The elastic bollard for rack protection is installed in front of a rack structure to effectively cushion external shocks and prevent damage to the rack structure. When a vertical pole installed upright on the ground is subjected to shocks from various directions, the vertical pole will tilt in the direction in which the external force is applied. An elastic part is installed inside the bollard so that the vertical pole can be restored to its original upright state by elastic force as soon as it tilts in the direction of the applied external force, thereby absorbing and mitigating the impact more effectively. The case itself is equipped with an elastic cushioning part to maximize the shock mitigation effect.SELECTED DRAWING: Figure 13

Description

[Technical Field]

[0001] The present invention relates to a resilient bollard for protecting a rack, and more particularly to a resilient bollard for protecting a rack that is installed in front of the rack to effectively buffer external impacts and prevent damage to the rack structure. [Background technology]

[0002] Generally, a vertical multi-tiered rack structure is used to efficiently store items in boxes or pallets in logistics warehouses, sales areas, etc. Since the rack is manufactured with multiple tiers, it must be manufactured very sturdy to support the weight of the rack structure itself and the items loaded on each tier of the rack. Furthermore, it is necessary to minimize external impacts applied to the rack structure in order to prevent accidents in advance, such as damage to parts of the rack structure and collapse of the structure.

[0003] In large warehouses, forklifts and the like are used to handle and transport product pallets and to load and unload them in multiple layers onto and from shelf racks. Forklifts are equipped with forks on the front of the forklift, which are inserted into the spaces between pallets and then lifted to transport the pallets. When transporting product pallets using a forklift, there have been frequent cases where the forklift driver was careless or the driver's forward vision was blocked by the pallets, resulting in impacts being applied to warehouse structures, i.e., the vertical posts of the shelf racks.

[0004] The impacts and the weight of products stacked in multiple layers can weaken the structure of the shelf rack, and repeated collisions can cause the shelf rack itself to collapse, leading to a major disaster. To prevent direct impacts on the shelf rack, bollards or bollard fences are installed at regular intervals on the ground in front of the shelf rack. A typical bollard, such as the pedestrian protection bollard in Application No. 10-2021-0160961, has a support pipe with a buffer section that is fitted into a pipe holder whose bottom is embedded in the ground, preventing localized deformation of the support pipe and dispersing the impact during a collision. However, because the bollard is fixed to the ground and installed upright, its impact mitigation effect in all directions is limited.

[0005] In contrast, the present invention relates to a resilient bollard for protecting racks, which is installed on the ground and has elasticity that can absorb external impacts in all directions. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Republic of Korea Patent Application No. 10-2021-0160961 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention relates to a resilient bollard for protecting a rack, and aims to provide a resilient bollard for protecting a rack that can smoothly buffer impacts caused by collisions that may occur in all directions. [Means for solving the problem]

[0008] In order to solve the above problem, The present invention solves the problem by providing an elastic bollard for protecting racks, which comprises a support part installed on the ground, a buffer part placed on the upper surface of the support part, a vertical pole connected to the buffer part, and a case part having a ground fixing part that can be firmly fixed to the ground, an insertion hole formed on the upper surface so that the vertical pole can pass through and protrude to the outside, an internal void part that can cover the support part and the buffer part, and

[0009] Also, the present invention solves the problem by providing an elastic bollard for rack protection that has an elastic part including one of an individual spring, a cylinder spring, or an elastic body on the bottom surface of the case part and the top surface of the buffer part, and can absorb and mitigate the impact when the vertical pole tilts due to an external force. Also, the present invention solves the problem by providing an elastic bollard for protecting a rack, which has an elastic buffer part in the case part itself and can absorb external impacts. [Effects of the Invention]

[0010] The present invention relates to an elastic bollard for rack protection. When an impact is applied from various directions to a vertical pole installed upright on the ground, the vertical pole will tilt in the direction of the applied external force. However, an elastic part is installed inside the vertical pole, so that as the vertical pole tilts in the direction of the applied external force, it can return to its original upright state by the elastic force, thereby absorbing and mitigating the impact more effectively. Furthermore, the case itself is equipped with an elastic buffer part, which has the advantage of maximizing the impact mitigation effect. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, this will be described in more detail with reference to the accompanying drawings.

[0013] Prior to this, the terms and words used in this specification and claims should not be interpreted limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept that is consistent with the technical idea of ​​the present invention, based on the principle that the inventor can appropriately define the concept of the term in order to explain his / her invention in the best possible way.

[0014] Therefore, it should be understood that the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent the entire technical idea of ​​the present invention, and that there may be various equivalents and modifications that can be substituted for them at the time of this application.

[0015] The present invention relates to a resilient bollard for rack protection, The bollard is generally made up of a support part (20) that is installed on the ground, a buffer part (30) that can be placed on the top of the support part or installed directly on the ground, a vertical pole (50) that is connected to the buffer part, and a case part (10) that has a through-insertion hole (11a) formed on the top surface so that the vertical pole can pass through and protrude outward, an internal space part (13) that can cover the support part (20) and the buffer part (30), and a ground fixing part (12a) that can be firmly fixed to the ground. The bollard has an elastic part (40) that includes one of an individual spring (41), a cylinder spring (42), or an elastic body (43) between the bottom surface of the case part and the top surface of the buffer part, and can absorb and mitigate impact when the vertical pole (50) tilts due to external force.

[0016] In more detail, The case part 10 is composed of an upper case part 11 having a through insertion opening 11a formed on its upper surface, and a lower case part 12 connected to the lower end of the upper case part and having a ground fixing part 12a formed at its lower end, and the upper and lower case parts 11 and 12 are either connected as a single unit or an elastic buffer part 14 is connected as a single unit between the upper and lower case parts. In other words, the upper and lower case parts are integrated to form a single case part with an internal space, and the upper and lower case parts and the elastic buffer part are also integrated to form a single case part with an internal space 13.

[0017] The bottom surface of the support part 20 is fixed to the ground, and a recess 21 is formed on the top surface thereof. In addition, the buffer unit 30 has a mounting portion 31 on its bottom surface so that it can be mounted in the recess 21 of the support unit or directly on the ground, and a socket portion 32 can be additionally positioned on the top surface of the buffer unit, and the buffer unit 30 can be made of metal or elastic synthetic resin material. In other words, the support unit can be selectively used as needed.

[0018] The shapes of the support part and the buffer part are not limited to those shown in the drawings of the present application, and the shape of the support part can be changed depending on the ground on which it is installed or the installation method, and the recess of the support part can also be manufactured in various shapes depending on the shape of the mounting part on the bottom of the buffer part, and the mounting part on the bottom of the buffer part can also be changed depending on the shape of the ground on which it is installed, the installation method, or the shape of the support part.

[0019] Also, the vertical pole 50 may be integrally manufactured with the buffer part 30 or may be fixedly coupled to a socket part 32 located on the upper surface of the buffer part.

[0020] The socket part may be manufactured integrally with the buffer part, or the buffer part and the socket part may be manufactured separately and then coupled or assembled. In particular, when the socket part and the buffer part are made of different materials, they may be manufactured separately and then coupled or assembled. When the socket part and the buffer part are made of the same material, they may be manufactured integrally or separately and then coupled or assembled.

[0021] In addition, the elastic part 40 may be installed on the bottom surface of the upper case 11 and the top surface of the buffer part, and may be composed of one or more individual springs 41 installed on the top surface of the buffer part at the outer corner of the vertical pole 50, one or more cylinder springs 42 installed to be penetrated by the vertical pole 50, or one or more elastic bodies 43 installed to be penetrated by the vertical pole 50. The elastic bodies 43 may be made of a synthetic resin material having elasticity and may be manufactured in a doughnut shape or a doughnut shape with a sawtooth shape (not shown) on the top surface. In order to fix the elastic part 40 when it is installed on the bottom surface of the upper case 11 and the top surface of the buffer part 30 so that it does not come off, protrusions (not shown) for fixing each elastic part may be formed on the bottom surface of the upper case 11 and the top surface of the buffer part, but this is obvious from known technology and will not be described separately.

[0022] In order to install the support or buffer part on the ground, bolts, nuts or anchors may be used, but the installation method is obvious from existing known inventions and will not be described separately.

[0023] In addition, in order to fix the case part to the ground, the case part can be fixed to the ground by fastening a bolt, nut or anchor body to the ground fixing part 12a, but the installation method is obvious from the analogy of existing publicly known inventions, so it will not be described separately.

[0024] As an example, 1 to 4, when an external force is applied to the vertical pole 50 from the left side, the vertical pole tilts to the right, but the right side of the elastic part 40 installed on the bottom surface of the upper case and the upper surface of the buffer part is compressed by the left external force, and the elastic force of the compressed right side of the elastic part causes the vertical pole to return to its upright state. Also, as shown in Figures 11c and 12c, when an external force is applied to the vertical pole from the left side, the vertical pole tilts with the right inner wall of the through-insertion hole formed in the upper case as its limit. If the left external force is strong, the right side of the elastic buffer part 14 is compressed between the upper and lower case, causing the vertical pole to tilt further to the right, and the elastic force of the right side of the elastic buffer part causes the vertical pole to return to its upright state.

[0025] When an external force is applied to the vertical pole, the vertical pole tilts with the inner wall of the insertion hole as a limit, and the more the vertical pole tilts, the more the elastic portion is compressed.

[0026] As described above, the present invention has been described using specific details such as concrete components, limited examples, and drawings. However, this is merely provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above examples. Various modifications and variations can be made from such descriptions by those having ordinary knowledge in the field to which the present invention pertains.

[0027] Therefore, the concept of the present invention should not be limited to the described embodiments, and all aspects that are equivalent or have equivalent modifications to the scope of the claims, as well as the scope of the claims, can be said to fall within the scope of the present invention.
