Description

Technical Field

[0001] The present invention relates to a multifunctional sliding device, and more specifically, to a multifunctional sliding device connected to a safety rope to ensure the safe movement of workers working at heights, wherein the multifunctional sliding device includes a fixing member, which is configured to have two fixing parts that are detachably coupled in different directions, one fixing part is fixedly coupled to a supporting target object such as a scaffolding at a construction site, and the other fixing part is coupled to a mounting member, and a fixing unit is provided in each fixing part of the fixing member, and the fixing unit can fix the coupling position while maintaining the coupling state of the clamp, wherein the mounting member is a fixed target object for the roller part of the sliding member connected to the safety rope to roll, and the clamp is used to detachably couple the target object to a recessed mounting groove of a clamp housing. Background Art

[0002] According to the supplementary statistics on the current status of industrial accidents in South Korea's Ministry of Employment and Labor, "The Current Status of Accident Deaths among Disaster Survey Subjects in 2022", among the 644 fatal accidents in 2022, 388 people died from falling accidents, accounting for 60% of all deaths.

[0003] Safety devices for preventing such falls have been proposed and their use has been mandated.

[0004] For example, Korean Patent No. 10-1208817 (authorized on November 29, 2012; multifunctional guide frame) proposes a multifunctional guide frame, which includes: a guide tube, a portion of one side of which is open along the length direction; a roller member, the head of which is combined with the internal guide of the guide tube; and a guide hole formed in the guide tube.

[0005] In the above-mentioned prior art, in order to set the guide tube for the roller member to slide, not only does it need to additionally set a support platform, but also the roller member installed inside the guide tube and partially exposed to the outside for connecting the safety rope can slide inside the guide tube only after the continuous guide tubes are connected and set. Therefore, there is a disadvantage that the guide tube must be connected and set continuously and without interruption in the entire section.

[0006] In addition, Korean authorized patent No. 10-2055377 (authorized on December 6, 2019; safety ring for preventing falls) proposes a safety ring for preventing falls, which includes: a ring body, which is circular and has an opening of a certain length formed along the circumference; and a pair of opening and closing fingers that can be elastically inserted and protruded at both ends of the ring body, and adjust the width of the opening to allow the ring body to be combined with or separated from the scaffolding.

[0007] In the prior art, when the ring body moves along the horizontal tubes of the scaffold, the opening and closing fingers arranged at both ends of the opening of the ring body adjust the width of the opening by elastically operating the vertical tube parts of the scaffold while allowing the ring body to pass. This concept is based on the premise that all horizontal tubes of the scaffold are arranged on the inner side of the workers, and all vertical tubes are arranged on the outer side of the workers, and it has the disadvantage of limited scope of application. At the same time, the opening and closing fingers of the prior art are configured to elastically limit the opening width of the ring body when contacting the scaffold tube, and when a concentrated load such as a fall of the worker occurs, the opening and closing fingers contact the scaffold tube, and in this case, the opening and closing fingers are opened while contacting the scaffold tube, so the effect of preventing falling may be questioned.

[0063] Hereinafter, the present invention will be described in detail using the accompanying drawings. However, since the accompanying drawings show preferred embodiments of the present invention, the scope of the present invention is not limited by these drawings. Furthermore, even if it is a structure necessary for implementing the present invention, for a structure that belongs to the known technology or can be easily implemented by those skilled in the art according to the known technology, its specific description will be omitted.

[0064] The multifunctional sliding device 10 of the present invention is used to prevent workers from falling during high-altitude operations. Figure 1 As shown, it is mainly used on the system scaffolding at the construction site. The present invention is described on the premise that the sliding device 10 is set on the system scaffolding and used. However, the sliding device 10 of the present invention can also be used in various aspects besides the system scaffolding, such as greenhouses, cranes, building management work lines, etc.

[0065] like Figures 1 to 4 As shown, the multifunctional sliding device 10 of the present invention includes: a fixing member 100, wherein the fixing unit 120 is arranged on two fixing parts 110 for fixing target objects in different directions respectively; an installation member (200), wherein a fixing head 210 is combined with one of the fixing parts 110, and a guide tube part 220 is integrally arranged on the fixing head 210; and a sliding member 300, wherein the sliding member 300 slides along the guide tube part 220.

[0066] The fixing member 100 may be provided in plurality along the working path, and the plurality of fixing members 100 may be linearly and continuously combined with only the mounting member 200 but not with the connecting member 400. However, preferably, as Figure 1 As shown, one fixing member 100 is combined with one mounting member 200 , and another mounting member 200 adjacent to the one mounting member 200 is connected to the connecting member 400 .

[0067] like Figure 1As shown, the fixing member 100 can be set on the joist tube 3 provided with a working platform in the system scaffold formed by connecting the vertical tube 1 and the horizontal tube 2. However, it is not limited to this. Not only can it be fixedly set on the vertical tube 1 or the horizontal tube 2, but also the fixing member 100 can be set even if the tubes are in a vertical relationship or a horizontal relationship. The reason why it can be set in so many positions is that the fixing member 100 is provided with two fixing parts 110, and the fixing parts 110 can be fixedly combined in different directions. And, on this basis, the scaffold including the joist tube 3, the vertical tube 1 and the horizontal tube 2 combined to the fixing part 110 is fixedly combined to each fixing part 110 by the fixing unit 120, and the combined position is fixed.

[0068] Reference Figure 2 and Figure 3 Each of the fixing parts 110 includes a clamp 112, which is fixedly coupled to a target object inserted into a clamp housing 111. The clamp housing 111 is provided with a recessed installation groove 111a for inserting and installing the target object.

[0069] like Figure 2 As shown, the two fixing parts 110 detachably combined in different directions can be formed by two pairs of opposite side walls 111c, wherein the parallel sides of a support plate 111b having a quadrilateral shape are bent and extended perpendicularly to each other in pairs, and each pair of opposite side walls 111c can be formed in opposite directions. Different from this, two pairs of opposite side walls 111c formed in opposite directions can also be arranged on different support plates 111b respectively and then combined with each support plate 111b. A recessed mounting groove 111a in the shape of a groove is formed at the extended end of the opposite side wall 111c formed as described above.

[0070] In addition, the pair of opposite side walls 111 c may be formed with an axial through hole 111 e and an opposite through hole 111 d penetrating through each of the opposite side walls 111 c on both sides along a straight line.

[0071] The shaft through hole 111e is provided with a shaft rod 114, and the clamp 112 is provided on the shaft rod 114 to install and fix the target inserted into the recessed installation groove 111a, and the clamp 112 includes a pair of jaws 112a, and the pair of jaws 112a are arranged in a relative structure so as to perform a rotational movement with the shaft hole 112c corresponding to the shaft rod 114 as the axis. The center of the pair of jaws 112a is inserted into the shaft rod 114, and the clamp 112 as a whole can perform elastic operation through the torsion spring 113 whose two ends are respectively clamped and fixed to the ends of the pair of jaws 112a.

[0072] Furthermore, a pair of jaws 112 a constituting the clamp 112 may have jaws formed therethrough. The jaw through-hole 112 b and the opposing through-hole 111 d formed through the opposing side wall 111 c are configured to be used for installing the fixing unit 120 .

[0073] That is, when the target object contacts the end of the recessed installation groove 111a and is pushed into the end of the recessed installation groove 111a, the pair of jaws 112a closing the entrance of the recessed installation groove 111a are opened with the shaft 114 as the axis by the elastic operation of the torsion spring 113, and the target object enters and is installed in the recessed installation groove 111a. When the installation of the target object is completed, due to the contraction of the torsion spring 113, the pair of jaws 112a close the entrance of the recessed installation groove 111a through the retracted clamping operation, thereby fixing the target object on the recessed installation groove 111a.

[0074] On the other hand, when the clamping action of the pair of jaws 112a, i.e., the clamp 112 is completed, the relative through hole 111d and the jaw through hole 112b are arranged in a straight line. The fixing unit 120, which is a rod-shaped unit that crosses the relative through hole 111d and the jaw through hole 112b, is inserted into the relative through hole 111d and the jaw through hole 112b installed in a straight line. The clamp housing 111 and the clamp 112 are integrated by the fixing unit 120 inserted into the relative through hole 111d and the jaw through hole 112b to stably and firmly fix and support the target object. As a result, there are the following advantages: even if an external force is generated on the target object and / or the sliding device 10, the target object fixed to the fixing portion 110 can maintain a constant connection state without worrying about separation, and at the same time, the connection position of the target object and the fixing member 100 is stably kept fixed.

[0075] In the above, the fixing unit 120 is generally rod-shaped. Figure 3 As shown, in the insertion portion 121 at one end of the rod-shaped fixing unit 120, its end can be gradually narrowed to be inserted into the through hole, and a handle ring can be provided on the rod handle portion 122 at the other end of the rod-shaped fixing unit 120 for grasping.

[0076] In addition, in the insertion portion 121 of the fixing unit 120 , the engaging operation ball 121 d elastically engaged in the inserted through hole may be elastically supported on the coupling pad 121 b by the elastic spring 121 c and disposed in the insertion hole 121 a of the insertion portion 121 .

[0077] The mounting member 200 includes: a fixed head 210 fixedly coupled to any one of the fixing parts 110; and a guide tube 220 integrally formed on the fixed head 210. The fixed head 210 can be connected to the guide tube 220 along the length direction through a plate-shaped mounting connection part 230.

[0078] The fixed head 210 includes a protruding head 211 capable of ensuring the bonding force with the clamp 112 set in the fixed part 110. The two side surfaces of the protruding head 211 are formed to protrude outward along the length direction, and are formed at the upper end of the mounting connection part 230, and can be in a "T" shape. In addition, a head fixing port 212 is formed in the central part of the cross section of the fixed head 210 formed in this way, which can be formed in the form of a groove at both ends in the length direction, or in the form of a through hole along the entire length direction, or differently from this, at both ends in the length direction, in the form of a protruding coupling rod, or by a corresponding coupling method among various coupling methods of a fixed connecting rod 213 whose ends are in the form of a through hole or a groove are connected to each other.

[0079] The guide pipe portion 220 is configured to allow the roller portion 310 of the sliding member 300 to be described to slide. Preferably, the guide pipe portion 220 is configured to allow the roller portion 310 to slide on the outer circumferential surface of the guide pipe portion 220 in the length direction, and a round steel pipe with a diameter of 48.6 mm x a thickness of 2.3 mm, which is generally used as a scaffolding pipe at a construction site, is used to facilitate the rolling of the roller portion 310. However, the shape of the guide pipe portion 220 is not limited to a round pipe, and a polygonal pipe such as a triangular pipe or a quadrangular pipe may also be used if necessary.

[0080] When the guide tube 220 is formed as a circular tube, a portion of the outer circumferential surface of the circular tube may be formed as a guide surface 223, which is a flat surface along the length direction. Along the guide surface 223 formed in this way, the roller 310 of the sliding member 300 is in close contact and slides, and since the roller of the roller 310 is in contact and rolls over a large area on the flat horizontal surface of the guide surface 223, even if the guide tube 220 is formed as a circular tube, the roller 310 can roll along the guide surface 223 in a state with a certain directionality without rotating along the circumferential direction of the circular tube.

[0081] In addition, the guide tube portion 220 may be connected to another adjacent guide tube portion 220, that is, the guide tube portions 220 may be directly connected to each other. In this case, the fixed head portion 210 formed integrally with one guide tube portion 220 may also be configured to be directly connected to another fixed head portion 210 formed integrally with another guide tube portion 220. Different from this, if necessary, as Figure 1As shown, the connecting pipe portion 410 of the connecting member 400 may also be configured to be able to connect one guide pipe portion 220 to another guide pipe portion 220 therethrough.

[0082] As described above, connection interfaces 221 may be formed at both ends of the guide pipe 220 in the length direction so that one guide pipe 220 is connected to another guide pipe 220 or to the connection pipe 410 of the connection member 400 .

[0083] The connection interface 221 can be formed at both ends of the guide tube portion 220 in the length direction. The connection interface 221 is formed in the form of a groove, or in the form of a through hole that passes through the length direction. Alternatively, it can be formed in the form of a protruding coupling rod at both ends in the length direction, or by various coupling methods of the interface connecting rods 222 that connect the ends in the form of through holes or grooves to each other. Corresponding coupling methods.

[0084] Preferably, if Figure 5 As shown, the connection interface 221 may further include a reinforcing rib 221 a for improving its own reinforcement. The interior of the reinforcing rib 221 a is integrally penetrated, and the reinforcing rib 221 a is formed along the inner diameter at at least two locations.

[0085] In addition, in the above, one mounting member 200 can be directly connected to another mounting member 200. In this case, the fixed heads 210 can be connected to each other through the fixed connecting rod 213, and the guide tubes 220 can be connected to each other through the interface connecting rod 222. Due to such a combination characteristic, the mounting members 200 have a certain directionality, so that even if an external force occurs, a certain directional combination force can be maintained, thereby ensuring the stable sliding of the sliding member 300 sliding on the guide tube 220.

[0086] like Figure 1 As shown, when the mounting members 200 coupled to the fixing member 100 are spaced apart from each other, the spaced apart mounting members 200 are connected to each other in a row by the connecting member 400 so that the sliding member 300 can move uninterruptedly.

[0087] Therefore, at least in the structure of the mounting member 200, the guide pipe part 220 on which the sliding member 300 slides must be allowed to be connected. That is, the guide pipe parts 220 arranged separately are connected to each other by the connecting member 400, and include a connecting pipe part 410 formed in an image corresponding to the guide pipe part 220, so that the sliding member 300 sliding on the guide pipe part 220 can slide continuously and smoothly on the connecting member 400 connected to the guide pipe part 220 without any resistance.

[0088] The connecting pipe part 410 has a shape corresponding to the guide pipe part 220 so that the sliding member 300 sliding on the guide pipe part 220 can slide continuously and smoothly without resistance. Therefore, when the guide pipe part 220 is formed as a circular pipe, the connecting pipe part 410 is also formed as a circular pipe the same as the guide pipe part 220. In addition, when the guide pipe part 220 is formed as a triangular or quadrangular polygonal pipe, the connecting pipe part 410 is also formed as a triangular or quadrangular polygonal pipe corresponding thereto.

[0089] In addition, when the connecting tube portion 410 is formed as a circular tube, a flat surface corresponding to the guide surface 223 (the flat surface of the guide tube portion 220), namely, a connecting surface 411, is formed on the connecting tube portion 410. The connecting surface 411 is a flat surface formed flatly along the length direction of a portion of the outer peripheral surface of the connecting tube portion 410 formed as a circular tube. Along the connecting surface 411 formed in this way, the roller portion 310 of the sliding member 300 is in close contact and rolls. Since the roller of the roller portion 310 is in contact and rolls over a large area on the flat horizontal surface of the connecting surface 411, even if the connecting tube portion 410 is formed as a circular tube, the roller portion 310 can roll along the connecting surface 411 in a state with a certain directionality without rotating along the circumference of the circular tube.

[0090] Also, a connection head portion 420 corresponding to the fixed head portion 210 of the mounting member 200 may be connected to the connection pipe portion 410 through an intermediate connection portion 430 .

[0091] In addition, the connecting pipe part 410 and the connecting head part 420 have a connecting interface 412 and a connecting fixing port 421 respectively connected to the guide pipe part 220 and the fixing head part 210 at both ends in the length direction. The connecting interface 412 and the connecting fixing port 421 can be formed in the form of an insertion groove, a through hole, a protruding rod or a connecting rod corresponding to the connecting interface 221 and the head fixing port 212.

[0092] The connection interface 412 is provided at both ends of the connection tube 410 in the length direction and is directly connected to the connection interface 221 of the guide tube 220, or is connected via the interface connection rod 222. In addition, the connection fixing port 421 is provided at both ends of the connection head 420 in the length direction and is directly connected to the head fixing port 212 of the fixed head 210, or is connected via the fixed connection rod 213.

[0093] In addition, after the connecting pipe part 410 of the connecting member 400 is connected to the connecting head part 420 as a whole through the intermediate connecting part 430, it can be connected to the guide pipe part 220 and the fixed head part 210 of the mounting member 200 by using the interface connecting rod 222 and the fixed connecting rod 213. In this case, since the fixed head part 210 is connected to the connecting head part 420 through the connecting and fixing port 421, and the guide pipe part 220 is connected to the connecting pipe part 410 through the interface connecting rod 222, the connecting member 400 can be connected to the mounting member 200 while maintaining a certain directionality, and thus has the advantage of ensuring the stable sliding of the sliding member 300 sliding on the guide pipe part 220.

[0094] The sliding member 300 includes a roller portion 310 that rolls on the guide tube portion 220 of the mounting member 200 and / or the connecting tube portion 410 of the connecting member 400. The safety rope 4 may be disposed on one side of the sliding member 300, such as Figure 4 As shown, preferably, the safety rope portion 330 is detachably connected to the lower portion of the roller housing 320 .

[0095] The roller housing 320 provided with the roller portion 310 may be formed to correspond to the shape of the guide tube portion 220 and / or the connecting tube portion 410, and preferably, may be formed to include an opening portion that is partially opened in a circular ring corresponding to the guide tube portion 220 and / or the connecting tube portion 410 formed as a circular tube. With the formation of the opening portion, interference between the mounting member 200 and / or the connecting member 400 and the connecting portion 230 and / or 430 does not occur.

[0096] In addition, the roller shell 320 is provided with a roller portion 310 that slides along the outer circumference of the guide tube portion 220 and / or the connecting tube portion 410, but preferably, the first roller portion 310a, the second roller portion 310b and the third roller portion 310c are formed in the shape of an equilateral triangle.

[0097] The first roller portion 310a provided at the base of the equilateral triangle is configured to slide on a large area of ​​the guide surface 223 and / or the connecting surface 411 which are flat surfaces of the guide tube portion 220 and / or the connecting tube portion 410. Thus, even if the guide tube portion 220 and / or the connecting tube portion 410 is formed as a circular tube, the first roller portion 310a contacts a large area of ​​the guide surface 223 and / or the connecting surface 411, so that the sliding member 300 can perform linear motion instead of rotating in the circumferential direction of the circular tube.

[0098] The second roller 310b and the third roller 310c are respectively provided on the two equal sides of the equilateral triangle.
