Description

Technology Field

[0001] The present invention relates to a wall fixing structure separation and dismantling device capable of easily and quickly separating and dismantling a wall fixing structure fixedly installed on a building wall. Background Technology

[0002] It is common practice to install security bars on windows or doorways for the safety and security of buildings. Security bars are effective in preventing external intrusion and are widely used not only in residential buildings but also in commercial and public facilities. In particular, sturdy security bars are frequently installed on windows in spaces such as semi-basement homes for security reasons.

[0003] However, these security bars can actually hinder residents' escape in emergency situations. For instance, there have been reported cases where residents in semi-basements were unable to evacuate quickly during floods, or where residents were unable to escape through windows during fires, resulting in casualties.

[0004] To address these issues, security bars with an easy-to-escape structure have been developed; however, they still have drawbacks, such as being difficult to quickly detach or dismantle in emergency situations or difficult to use without separate tools.

[0005] Therefore, there is a need for technology that allows for rapid dismantling and escape in emergency situations while maintaining existing security functions.

[0006] Accordingly, the applicant proposes a technology that allows for the rapid and easy separation and dismantling of structures fixed to building walls, such as security bars, in emergency situations, and which can be utilized as a life-saving device in public offices such as fire stations.

Specific details for implementing the invention

[0021] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms; these embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention. Identical reference numerals in the drawings refer to identical elements.

[0022] A wall-fixed structure separation and dismantling device according to a preferred embodiment of the present invention can quickly and easily separate and dismantle a structure fixedly installed on a building wall from the wall surface, and accordingly, can provide various effects such as saving lives through the dismantling of the structure.

[0023] The present invention will be described in detail below with reference to examples.

[0024] As illustrated in FIGS. 1 to 3 and FIG. 7, the wall-fixing structure separation and dismantling device according to an embodiment of the present invention is configured to separate and dismantle a plurality of horizontal bars (20) and vertical bars (30) fixed to a wall surface, and to perform various separation and dismantling operations such as separating a structure (10) formed by the combination of a plurality of horizontal bars (20) and vertical bars (30) from the wall surface, separating a vertical bar (30) from a horizontal bar (20), cutting a vertical bar (30), or separating a horizontal bar (20) from a vertical bar (30). The wall-fixing structure separation and dismantling device according to an embodiment of the present invention is configured in a structure and form that can be easily used while being carried by a worker.

[0025] Here, the structure (10) can be applied as a security window installed for security purposes on the exterior window of a residential unit, for example. In addition, the horizontal bar (20) and the vertical bar (30) may have a cross-sectional shape such as a circle or a square.

[0026] To elaborate, as illustrated in FIG. 1, the structure (10) is composed of a square frame bar that is fixed to a wall to form a frame, a horizontal bar (20) connected horizontally to the square frame bar, and a plurality of vertical bars (30) connected vertically to the square frame bar.

[0027] The wall fixing structure separation and dismantling device according to an embodiment of the present invention is configured to perform various dismantling operations, such as cutting the horizontal bar (20) and the vertical bar (30), separating the vertical bar (30) from the square border bar, separating the horizontal bar (20) from the square border bar, separating the vertical bar (30) from the horizontal bar (20), or separating the horizontal bar (20) from the vertical bar (30).

[0028] To elaborate, the horizontal bar (20) and the vertical bar (30) can be combined in various ways when connected to the square border bar, and the commonly used methods are as follows.

[0029] For example, as a bolt and nut connection method, the horizontal bar (20) and the vertical bar (30) are fixed by drilling holes in the square frame bar and using bolts and nuts.

[0030] As another example, as an insert method, a groove (slot) into which a horizontal bar (20) and a vertical bar (30) are inserted is pre-machined into a square frame bar, inserted, and fixed with a screw.

[0031] A worker can use a wall fixing structure separation and dismantling device according to an embodiment of the present invention to twist or bend the crossbar (20) to separate the bolts, nuts, screws, etc. installed at the connection part between both ends of the crossbar and the square frame bar, thereby separating the crossbar from the square frame bar.

[0032] In addition, the worker can use a wall-fixing structure separation and disassembly device to twist or bend the vertical bar (30) to separate the bolts, nuts, screws, etc. installed at the connection points between both ends of the vertical bar and the square frame bar, thereby separating the vertical bar from the square frame bar.

[0033] Additionally, the worker can cut the vertical bar (30) using a wall-fixing structure separation and disassembly device, and then pull the cut vertical bar (30) forward to separate the bolts, nuts, screws, etc. installed at the connection point between the end of the vertical bar (30) and the square frame bar, thereby separating the vertical bar from the square frame bar.

[0034] Additionally, the worker can cut the crossbar (20) using a wall-fixing structure separation and dismantling device, and then pull the cut crossbar (20) forward to separate the bolts, nuts, screws, etc. installed at the connection part between the end of the crossbar (20) and the square frame bar, thereby separating the crossbar from the square frame bar.

[0035] As illustrated in FIGS. 2 to 6, a wall-fixing structure separation and dismantling device (hereinafter referred to as the 'dismantling device') according to an embodiment of the present invention includes a block (100), a handle (200), and a cutting plate (300).

[0036] As illustrated in FIGS. 2 to 6, the block (100) has at least one groove (110) formed so that a horizontal bar (20) or a vertical bar (30) can be inserted.

[0037] FIGS. 2 and 3 show a vertical bar (30) inserted into a groove (110), but are not limited thereto, and a horizontal bar (20) may also be inserted into the groove (110). The groove (110) may have a cross-sectional shape corresponding to the cross-sectional shape of the horizontal bar (20) and the vertical bar (30), but is not necessarily limited thereto.

[0038] The handle (200) is integrally connected to the block (100) and is configured to apply external force to bend or cut the horizontal bar (20) or the vertical bar (30).

[0039] As illustrated in FIGS. 2 and 3, with the vertical bar (30) inserted into the groove (110), the user can lift or lower the handle (200) in the up-and-down direction relative to the drawing to cause the block (100) to apply an external force to the vertical bar (30). The vertical bar (30) can be bent or cut upon receiving this external force, and in this case, the upper part of the vertical bar (30) connected to the horizontal bar (20) can be easily separated from the horizontal bar (20), thereby allowing the vertical bar (30) to be separated from the horizontal bar (20) more easily.

[0040] In an embodiment of the present invention, as illustrated in FIGS. 2 to 6, a plurality of grooves (110) are formed in the block (100), and the plurality of grooves (110) are formed to have different angles of inclination with respect to the block (100). Although the related drawings show a case where two grooves (110) are formed, it is acceptable to form three or more.

[0041] When a user wants to insert the vertical bar (30) into the groove (110) to bend it in order to separate and disassemble the vertical bar (30) from the horizontal bar (20), the multiple grooves (110) are formed to have different angles of inclination so that it is easy to apply force while holding the handle (200) at a desired position and angle.

[0042] That is, the user can apply an external force to the vertical bar (30) by inserting the vertical bar (30) into a desired groove (110) among the multiple grooves (110) and rotating the block (100) through the handle (200).

[0043] As illustrated in FIGS. 4 to 7, the cutting plate (300) has at least one blade groove (310) into which a horizontal bar (20) or a vertical bar (30) is inserted to cut the horizontal bar (20) or the vertical bar (30). Here, the term blade groove (310) means that a blade is formed on the inner wall forming the groove.

[0044] This cutting plate (300) is slidably coupled to the block (100), and when the cutting plate (300) is not in use, the cutting plate (300) is not allowed to have the blade groove (310) protrude to the outside of the block (100) as shown in FIG. 4, and when the cutting plate (300) is in use, the cutting plate (300) can be slid forward so that the blade groove (310) protrudes to the outside of the block (100) as shown in FIG. 7.

[0045] Therefore, when the cutting plate (300) is not used or the dismantling device according to the present invention is stored, the blade groove (310) is prevented from protruding outside the block (100), thereby minimizing the risk of injury to the user's body from coming into contact with the blade groove (310).

[0046] As illustrated in FIG. 7, the user can slide the cutting plate (300) forward of the block (100), insert the vertical bar (30) into the blade groove (310) and bring the vertical bar (30) into contact with the inner surface of the blade groove (310), and then cut the vertical bar (30) in the transverse direction while rotating the handle (200) left and right.

[0047] At this time, it is preferable that the front surface of the block (100) adjacent to the horizontal bar (20) be spaced apart from the horizontal bar (20) by a certain amount.

[0048] Specifically, in FIG. 7, when the handle (200) is rotated clockwise for a certain amount of time, the front of the block (100) adjacent to the horizontal bar (20) comes into contact with the horizontal bar (20) and acts as a lever point, and at this time, the blade of the blade groove (310) applies a cutting force laterally to the vertical bar (30), and the vertical bar is cut.

[0049] In the present invention, a groove (110) is formed in the block (100), and a cutting plate (300) is additionally provided in the block (100), so that the bending separation operation and the cutting operation of the horizontal bar (20) or vertical bar (30) can both be performed using a single tool.

[0050] In an embodiment of the present invention, as shown in FIGS. 4, 5, 7, and 8, a block (100) and a cutting plate (300) are provided with a slide coupling structure for integrally coupling the cutting plate (300) to the block (100) while allowing it to slide.

[0051] This slide coupling structure includes an elongated hole (320), a fixing member (330), and an elastic pressing member (340).

[0052] The elongated hole (320) is formed along one side direction (length direction) of the cutting plate (300). Although it is acceptable to form only one elongated hole (320), it is preferable to provide multiple elongated holes (320) spaced apart from each other along one side direction of the cutting plate (300) to set the slide movement direction of the cutting plate (300).

[0053] The fixing member (330) has a cross-sectional area larger than the elongated hole (320) and is connected to the block (100) by penetrating the elongated hole (320).

[0054] Specifically, the fixing member (330) is connected to each of the multiple slots (320), and the block (100) is provided with multiple connecting grooves (120) so that the fixing member (330) is connected to each other along a direction corresponding to one side of the cutting plate (300) while being spaced apart from each other.

[0055] In the related drawings, an elastic pressure member installation groove (130) in which an elastic pressure member (340) described later is installed is shown to be formed in the block (100) along with a coupling groove (120), but it is not necessarily limited thereto.

[0056] The block (100) may be made of wood, and a separate metal plate (not shown) having a coupling groove (120) and an elastic pressure member installation groove (130) formed on the outer surface of the block (100) may be additionally fixedly connected.

[0057] In an embodiment of the present invention, the fixing member (330) includes a bolt (331) that is screw-coupled to the coupling groove (120) and a washer (332) that has a cross-sectional area larger than the width of the elongated hole (320) to prevent the cutting plate (300) from coming off the bolt (331).

[0058] As illustrated in FIGS. 4, 5 and 8, the elastic pressure member (340) constantly presses the bottom surface of the cutting plate (300) so that the top surface of the cutting plate (300) is in close contact with the bottom surface (bottom surface) of the fixing member (330), specifically the washer (332).

[0059] That is, as illustrated in FIGS. 4, 5 and 8, the elastic pressure member (340) elastically pressurizes and supports the bottom surface of the cutting plate (300) so that the bottom surface of the cutting plate (300) is spaced apart from the upper surface of the block (100) facing it by a certain amount or more, and when the user wants to slide the cutting plate (300), the user can slide the cutting plate (300) by holding it with their hand and pushing it forward and backward.

[0060] Here, the elastic pressure member (340) can be applied as a ball plunger and is installed so that the ball of the ball plunger makes rolling contact with the bottom surface of the cutting plate (300). Accordingly, the elastic pressure member (340) can not only stably elastically support the cutting plate (300) but also minimize contact friction with the cutting plate (300), thereby allowing the cutting plate (300) to slide back and forth more smoothly.

[0061] In the present invention, as shown in FIGS. 4, 5 and 7, a gripping portion (350) is formed protrudingly on the cutting plate (300) so that the user can slide the cutting plate (300) forward and backward in a direction corresponding to one side of the block (100) more easily, so that the cutting plate (300) can be grasped by hand and slide the cutting plate (300).

[0062] In an embodiment of the present invention, blade grooves (310) are formed on opposite sides of the cutting plate (300), and the user can cut the vertical bar (30) using the blade groove (310) that is more suitable for their posture and angle of use.

[0063] For example, as illustrated in FIGS. 4 and 5, a pair of blade grooves (310) formed on each side in the width direction of the cutting plate (300) may have the same shape as each other. These blade grooves (310) may have shapes such as circular, elliptical, triangular, or square.

[0064] As a variation example, as shown in FIG. 9, a pair of blade grooves (310) formed on each side in the width direction of the cutting plate (300) may be formed with different shapes. In this case, there is an advantage in that a blade groove (310) of an appropriate shape can be selected and used according to the cross-sectional shape of the vertical bar (30).

[0065] Although the present invention has been illustrated and described above in relation to preferred embodiments for illustrating the principles of the invention, the invention is not limited to the configuration and operation as illustrated and described. Rather, those skilled in the art will understand that numerous changes and modifications to the invention are possible without departing from the spirit and scope of the appended claims.
