Description

Technical Field

[0001] The present invention relates to a suspension ring device.

Background Art

[0002] Suspension rings are used for purposes such as temporarily suspending or pulling heavy objects such as steel materials and steel plates, or people such as workers, and are usually fixed to flat surfaces such as the structural parts of buildings and structures, concrete walls, ceilings, and floors.

[0003] Generally, this suspension ring is formed by providing a suspension hole of a predetermined size at a predetermined position on a steel suspension plate (flat bar), inserting suspension parts such as wires, hooks, and carabiners through this suspension hole, and welding both ends of the suspension part.

[0004] The suspension ring is constructed in the following manner. First, the suspension plate is embedded in the concrete of the target flat surface, and the concrete is placed, so that the suspension ring can be integrally constructed on the flat surface of the concrete. Heavy objects or temporary equipment can be suspended or supported on the suspension part of this suspension ring.

[0005] Here, a typical practical example of a suspension ring is, for example, a method of embedding a suspension ring on the wall surface at the peripheral edge of the roof of a high-rise building and using it as a suspension point to suspend a temporary gondola used for cleaning and repair work. A safety line for workers and a suspension rope for the temporary gondola are connected to this suspension ring, and workers can ride on the gondola to safely perform window wiping, exterior cleaning, and inspection work on the outer wall of the building.

[0006] Regarding such suspension rings, various technologies exist. For example, Japanese Patent Publication No. 2025-80245 (Patent Document 1) discloses a rope fixing device for building cleaning, comprising a main body case (10), a ring fastener (30), and a case bracket (20). The main body case (10) has a ring housing section (12) formed inside a housing with an open front, and a fastener fitting hole (13) formed at the top of the ring housing section (12). The ring fastener (30) has a rope ring (35) rotatably assembled on one side of the ring fixing plate (31), and the other side is inserted into the fastener fitting hole (13) of the main body case (10), and the building's reinforcing bar (3) is assembled into the reinforcing bar assembly hole (32) at the tip. The case bracket (20) is fixed to the lower part of the back of the main body case (10) and supported by the building's reinforcing bar (3). This design ensures that the binding device is directly connected to the building's reinforcing steel, preventing the case from moving and guaranteeing worker safety. Furthermore, side plate reinforcements are formed on the case's side panels to prevent distortion despite the pressure from concrete pouring, allowing the rope loops to move smoothly. Finally, a case bracket positioned at the bottom of the case's rear is connected to the reinforcing steel, ensuring that the case, supported by the binding device and case bracket, remains in place even during concrete pouring.

[0007] Furthermore, Utility Model Registration No. 3187122 (Patent Document 2) discloses a suspension ring that is installed on a flat surface such as a wall, ceiling, or floor of a building. This suspension ring comprises a suspension plate, a resin cylindrical body, and a substantially annular suspension part. One end of the suspension plate is fixed to a flat surface, and a suspension hole is drilled in the other end. The cylindrical body is fitted to the inner circumferential surface of the suspension hole, and the suspension part is inserted through the inner circumferential surface of the cylindrical body and welded. This makes it possible to prevent damage and noise caused by friction between the outer circumferential surface of the suspension part and the inner circumferential surface of the suspension hole in the suspension plate.

[0008] Furthermore, Japanese Patent Publication No. 2011-185024 (Patent Document 3) discloses a fall prevention and vibration prevention fitting for retrofitting suspension bolts that can cope with vertical and horizontal shaking during earthquakes. It states that it can be retrofitted to all-thread bolts for equipment suspension, and that the vibration-preventing all-thread bolt can be fixed without using fittings such as turnbuckles. It also states that by using it in combination with a wire-attached bolt, it is possible to prevent the fall of lighting fixtures such as system ceilings and downlights. Furthermore, it states that it can be retrofitted to all-thread bolts for equipment suspension, and that the vibration-preventing all-thread bolt can be attached without using fittings such as turnbuckles. Furthermore, it states that it can cope with vertical and horizontal shaking during earthquakes, and that by screwing the wire-attached bolt into a long nut with a hole, or by passing the wire-attached bolt through the hole and fixing it, it is possible to prevent the fall of lighting fixtures such as system ceilings and downlights.

[0009] Furthermore, Utility Model Registration No. 3190041 (Patent Document 4) discloses a fall prevention hook comprising a hook body, an opening / closing lever, and a safety latch. The hook body has a hook portion at the tip and an annular portion at the base, and the opening / closing lever rotates to open and close the hook opening of the hook body. The opening / closing lever is said to have a roughly inverted Y shape, with a pivot shaft on one of the Y-shaped bifurcations, pivotally supported near the base, and another pivot shaft on the other, and consists of a base portion slidably disposed in an elongated hole in the safety latch, and an arm portion extending from the Y-shaped bifurcations to open and close the hook opening. As a result, it does not require spreading the fingers to their fullest extent to grip, as in conventional hooks, making it very easy to grip, and preventing fingers from slipping downwards when gripped, allowing for quick and efficient attachment and detachment to a pipe. Furthermore, when gripping the opening / closing lever with your fingertips, your fingertips will sink into the recesses of the curved and bent sections formed in the lever. This prevents your fingertips from coming into contact with the pipe when attaching or detaching the lever, allowing for quick and efficient attachment and detachment.

[0010] [Patent Document 1] Japanese Patent Publication No. 2025-80245 [Patent Document 2] Utility Model Registration No. 3187122 Gazette [Patent Document 3] Japanese Patent Publication No. 2011-185024 [Patent Document 4] Utility Model Registration No. 3190041 (Gazette) [Overview of the project] [Problems that the invention aims to solve]

[0011] As mentioned above, suspension rings installed on flat surfaces are often installed on the walls around the edges of the rooftops of high-rise buildings. On the rooftops of high-rise buildings, the suspension portion of the suspension ring is prone to swaying due to strong winds. When the suspension portion sways, the tip of the suspension portion (free end) hits the wall or the suspension portion rubs against it, creating a loud noise and generating noise pollution. Such noise becomes a source of complaints from residents of high-rise buildings and surrounding areas. Furthermore, even when a case for housing the suspension ring is provided, as in the technology described in Patent Document 1 mentioned above, the tip of the suspension portion collides with the inner surface of the case, similarly creating noise pollution. Moreover, collisions between the suspension portion and the wall can lead to damage to both the suspension portion and the wall, compromising safety. The technologies described in Patent Documents 1-4 mentioned above cannot solve these problems.

[0012] Therefore, this invention was made to solve the aforementioned problems, and aims to provide a suspension ring device that can reliably prevent damage and noise caused by the swinging of the suspension part. [Means for solving the problem]

[0013] The suspension ring device according to the present invention comprises a case, an opening, a suspension plate, an annular suspension portion, and a fastening portion. The bottom surface of the case is embedded in the wall surface of a building, and the opening is formed at the upper end of the inner surface of the case. One end of the suspension plate is inserted through the opening and fixed to the wall surface, and a suspension hole is formed at the other end. One end of the suspension portion is inserted through the suspension hole and welded to the other end, and it is annular in shape. The fastening portion is provided inside the case so as to be detachable from a part of the suspension portion when it is stationary. [Effects of the Invention]

[0014] According to this invention, it is possible to reliably prevent damage and noise caused by the swinging of the suspension part. [Brief explanation of the drawing]

[0015] [Figure 1] This is a front perspective view showing an example of a suspension ring device according to the present invention. [Figure 2] This is a rear view perspective showing an example of a suspension ring device according to the present invention. [Figure 3] The present invention includes a reference perspective view (Figure 3A) showing an example of a suspension part in a stationary state, and a reference perspective view (Figure 3B) showing an example of a suspension part in use. [Figure 4] This is a front view showing examples of fasteners of various shapes. [Figure 5] Figure 5A shows a front perspective view of an example in which the position and number of fastening parts of the suspension ring device according to the present invention are changed, and Figure 5B shows a front perspective view of an example in which the position and number of fastening parts of the suspension ring device according to the present invention are changed. [Modes for carrying out the invention]

[0016] The following describes embodiments of the suspension ring according to the present invention with reference to the attached drawings, in order to facilitate understanding of the present invention. Note that the following embodiments are merely examples of the present invention and do not limit the technical scope of the present invention.

[0017] As shown in FIGS. 1-2, the suspension device 1 according to the present invention includes a case 10, an opening 11, a suspension plate 12, a suspension part 13, and a fastening part 14. Here, the bottom surface 10a of the case 10 is embedded in the wall surface W of the building, and the opening 11 is formed at the upper end 10b1 of the inner surface 10b (corresponding to the bottom surface 10a) of the case 10.

[0018] Moreover, one end 12a of the suspension plate 12 is inserted through the opening 11 and fixed to the wall surface W, and a suspension hole 12c is formed at the other end 12b. Further, one end 13a of the suspension part 13 is inserted through the suspension hole 12c and welded to the other end 13b. And the fastening part 14 is detachably provided on the inner surface 10b of the case 10 at a part 13c of the stationary suspension part 13 (for example, corresponding to the vicinity below the suspension part 13).

[0019] Thereby, it becomes possible to surely prevent damage and noise caused by the swinging of the suspension part 13. That is, as shown in FIG. 3A, when the user does not use the suspension part 13, by attaching a part 13c of the stationary suspension part 13 to the fastening part 14, the suspension part 13 is fixed to the case 10 via the fastening part 14. Therefore, even if the suspension part 13 swings due to wind, since it is fixed to the case 10 by the fastening part 14, the suspension part 13 does not collide with the inner surface 10b of the case 10 or generate noise due to swinging. As a result, damage and noise caused by the swinging of the suspension part 13 can be surely prevented.

[0020] Moreover, when the user uses the suspension part 13, as shown in FIG. 3B, a part of the suspension part 13 is removed from the fastening part 14 fixed to the case 10, and the suspension part 13 is used as a suspension point (suspension base) to suspend a suspension rope of a temporary gondola used for cleaning or repair work, or a lifeline of a worker. Thereby, the worker can ride on the temporary gondola and, for example, safely perform window wiping or exterior cleaning and inspection work on the building exterior wall.

[0021] Here, the shape of case 10 is not particularly limited as long as it does not hinder the purpose of the present invention. For example, as shown in Figure 1, it may be a cube with curved corners, a simple cube, a cylindrical body, a polygonal cylinder, or the like. Also, the material of case 10 is not particularly limited as long as it does not hinder the purpose of the present invention. For example, metals, stainless steel, or iron with excellent load-bearing capacity can be used.

[0022] Furthermore, the case 10 may be provided with a front receiving plate (flange) 10c that is bent outwards. Here, the front receiving plate 10c can prevent concrete from flowing into the inside of the case 10 when concrete is poured. In addition, the front receiving plate 10c has multiple screw holes 10d formed therein, and by inserting predetermined screws into the screw holes 10d, the case 10 can be properly fixed to the concrete wall surface.

[0023] In the present invention, the suspension ring device 1 is configured to house the suspension plate 12 and the suspension part 13 inside the case 12. Therefore, when embedding the case 12 in concrete, it is possible to place the concrete pouring wall formwork in contact with the front receiving plate 10c before pouring the concrete, thereby facilitating the installation of the wall formwork.

[0024] Furthermore, the side of the case 10 may be provided with a side reinforcing portion 10e that protrudes in the vertical direction, for example. Here, the side reinforcing portion 10e reinforces the side of the case 10, preventing the side of the case 10, which is installed inside the concrete, from being deformed by the concrete pressure. There are no particular limitations on the configuration of the side reinforcing portion 10e; for example, it may protrude in the left-right direction, or it may protrude in a cross shape in both the vertical and left-right directions.

[0025] Furthermore, the shape of the opening 11 is not particularly limited as long as it does not hinder the purpose of the present invention. For example, as shown in Figure 2, it may be a rectangle corresponding to the cross-sectional shape of the short side of the suspension plate 12, or it may be a square, circle, ellipse, rounded rectangle, etc., through which one end 12a of the suspension plate 12 can be inserted.

[0026] Furthermore, the shape of the suspension plate 12 is not particularly limited as long as it does not hinder the purpose of this invention. For example, as shown in Figure 1, it may be a plate with a semicircular tip, or it may be a simple plate. Also, in order to increase durability and fixing strength, for example, the suspension plate 12 may be a plate bent at a predetermined position, or a plate with a T-shaped base. Furthermore, the material of the suspension plate 12 is not particularly limited as long as it does not hinder the purpose of this invention. For example, metals, stainless steel, iron, etc., which have excellent load-bearing capacity, can be used.

[0027] Alternatively, a rebar assembly hole 12d may be provided at one end 12a of the suspension plate 12. The rebar assembly hole 12d allows the suspension plate 12 to be firmly fixed to the concrete wall W by inserting the reinforcing bars provided inside the concrete when constructing the concrete wall W.

[0028] Furthermore, the shape of the suspension portion 13 is not particularly limited as long as it does not hinder the purpose of this invention, but for example, it can be a perfect circular ring, an elliptical ring, or a polygonal ring. Also, the material of the suspension portion 13 can be a metal, stainless steel, iron, or the like, which has excellent load-bearing capacity and wear resistance.

[0029] Furthermore, the shape of the fastening portion 14 is not particularly limited as long as it does not hinder the purpose of this invention, but for example, as shown in Figure 4, it may be U-shaped, C-shaped, crescent-shaped, wing-shaped, M-shaped, etc. Also, the material of the fastening portion 14 is not particularly limited as long as it does not hinder the purpose of this invention, and for example, metal or resin can be used.

[0030] In this case, if the material of the fastening part 14 is made of resin, polyethylene, polystyrene, polypropylene, polyester, carbon fiber reinforced plastic, glass fiber reinforced plastic, aramid fiber reinforced plastic, or fiber-reinforced epoxy resin, which have excellent weather resistance and durability, can be used.

[0031] Furthermore, there are no particular limitations on the method of installing the fastening portion 14, as long as it does not hinder the purpose of the present invention. For example, the base end portion 14a of the fastening portion 14 may be welded to the inner surface 10b of the case 10 for fixation, or the base end portion 14a of the fastening portion 14 may be detachably fixed to the inner surface 10b of the case 10 by bolts or screws, or the base end portion 14a of the fastening portion 14 may be fixed by passing it through the inner surface 10b of the case 10.

[0032] Furthermore, there are no particular limitations on the number of fastening parts 14, as long as they do not hinder the purpose of this invention. For example, as shown in Figure 5A, a predetermined number of fastening parts 14 (e.g., 2) may be provided at positions corresponding to the lower part of the suspension part 13, or additional fastening parts 14 may be provided depending on the application. Also, as shown in Figure 5, the positions of the fastening parts 14 may be provided symmetrically, asymmetrically, or at predetermined intervals in the vertical direction.

[0033] Furthermore, in the suspension ring device 1 according to the present invention, a resin cylinder may be provided attached to the inner circumferential surface of the suspension hole 12c, and the suspension portion 12 may be made to pass through the inner circumferential surface of the cylinder. This prevents direct contact between the suspension portion 12 and the suspension hole 12c, and further suppresses wear and noise generation.

[0034] Here, the shape of the cylindrical body is not particularly limited as long as it does not hinder the purpose of this invention, but for example, cylindrical, elliptical, polygonal, etc. can be used. Also, the material of the cylindrical body is not particularly limited as long as it does not hinder the purpose of this invention, but for example, polyethylene, polystyrene, polypropylene, polyester, etc. can be used.

[0035] Furthermore, the suspension ring device 1 according to the present invention is used by attaching the hooking parts of wire ropes, chains, shackles, and hooks to the suspension part 13.

[0036] Furthermore, the buildings to which the suspension ring device 1 according to the present invention is applied are not particularly limited, as long as they do not hinder the purpose of the present invention. As mentioned above, they may be the rooftops of high-rise buildings, or other buildings such as factories, offices, residences, and houses. [Industrial applicability]

[0037] As described above, the suspension ring device according to the present invention is useful as a suspension ring device in the fields of architecture, construction, design, construction, maintenance, etc., and is effective as a suspension ring device that can reliably prevent damage and noise caused by swinging of the suspension part.
