Description

[Technical field]

[0001] The present invention relates to a fall prevention device that prevents infants and children from falling off verandas and balconies. The fall prevention device of the present invention can be used on both verandas and balconies, but here we will explain the use of the device on a veranda as a representative example. [Background technology]

[0002] There have been many accidents involving infants and children climbing over balcony railings and accidentally falling off. In particular, in recent years, there have been many tragic accidents involving people falling from balconies of high-rise apartment buildings, resulting in death or injury.

[0003] 2. Description of the Related Art Conventionally, fall prevention devices include fall prevention walls or fences that are attached to a balcony fence by a fixing device and stand upright above the fence (see Patent Documents 1 and 2).

[0004] In addition, handrails to prevent infants and children from climbing over are known, which consist of a rotating handrail that is installed concentrically around a support shaft or via a rotating bearing, as the handrail rotates when an infant or child places their hands on the top of the fence to prevent the infant or child from climbing over the fence (see Patent Documents 3 and 4).

[0006] Conventional fall prevention devices have a fall prevention wall that is not necessarily simple to install, has a large number of parts, and is not necessarily easy to install.

[0007] However, because fall prevention devices installed on balcony railings are placed facing the outside of the balcony, they are often exposed to wind and rain and are prone to deterioration over time. In particular, when exposed to external forces from wind and rain, the attachment part of the fall prevention device to the balcony railing is repeatedly subjected to external forces, and the fixing structure is likely to loosen or break.

[0008] For example, conventional fall prevention devices, as shown in the above-mentioned Patent Documents 1 and 2, employ a structure in which the lower part of a fall prevention fence is clamped by a fixing member to the upper part of a fixing member (balcony fence) and fixed with a bolt. With such a structure, the fixing structure is prone to loosening and damage.

[0009] The present invention aims to solve the above-mentioned problems in the conventional art, and its object is to realize a fall prevention device with a simple structure having a small number of parts, which is easy to attach to a balcony fence, and which has a configuration that suppresses rattling, does not loosen or come off when exposed to wind and rain, and is capable of maintaining its attachment strength. [Means for solving the problem]

BEST MODE FOR CARRYING OUT THEINVENTION

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will now be given of an embodiment of a fall prevention device for a balcony according to the present invention with reference to the drawings.

[0022] In the explanation of the embodiments below, when looking out from a balcony that juts out from a building with the building at its back, the outdoor side is defined as the outside of the balcony (or simply "outside"), and the width direction (longitudinal direction) along the balcony railing is defined as the horizontal direction (left-right direction) of the balcony railing.

[0023] In addition, the front view is when the fall prevention device is viewed from inside the balcony (building side), and the side view is when viewed from the side of the balcony. EXAMPLES

[0024] Example 1 A first embodiment of a fall prevention device 1 according to the present invention will be described with reference to FIGS.

[0025] The overall configuration of the fall prevention device 1 of Example 1, as shown in Figure 1, comprises a fall prevention member 2, a pillar 3 supporting both horizontal ends of the fall prevention member 2, a pillar support structure 7 supporting and reinforcing the lower part of the pillar 3 on the balcony floor 6 (or groove 71), a handrail fixing device 12 fixing the pillar 3 to a handrail 8 of an existing balcony fence 9, and a fall prevention member mounting device 13.

[0026] The pillars 3 support both lateral ends of the fall prevention member 2, the pillar support structure 7 supports and reinforces the lower part of the pillar 3 on the balcony floor 6 (or groove 71), and the fall prevention member mounting fixture 13 is a part that attaches the fall prevention member 2 to the pillars 3 (more specifically, parts that attach the upper frame 16 and lower frame 17 of the fall prevention member 2 to the pillars 3).

[0027] Depending on the structure of the balcony, the lower part of the support pillar 3 may be supported on the floor 6 or on a groove 71 formed in the floor 6 along the balcony fence as shown in Figures 10(a) and (c). Therefore, in this specification, it is described as the floor 6 (or groove 71) as described above, and in the drawings it is described as 6(71). The floor described in the claims is the floor 6 (or groove 71) shown in the examples.

[0028] The existing balcony fence 9 at least comprises a handrail 8 (upper cross rod) and a lower cross rod 11 arranged horizontally between adjacent support rods 10 (see Figures 3(a) and 4(a)) erected on the balcony floor 6 (or groove 71).

[0029] 1, the fall prevention member 2 is formed in a fence-like shape overall, and comprises an upper frame 16 and a lower frame 17 that are installed horizontally along the balcony, and a number of vertical bars 18 that are arranged at equal intervals in the horizontal direction between the upper frame 16 and the lower frame 17. The fall prevention member 2 is placed between adjacent posts 3, and is attached at both ends to the adjacent posts 3 with fall prevention member mounting fixtures 13.

[0030] In this embodiment, the fall prevention member 2 is fence-shaped, but it may have another structure that does not receive wind pressure over the entire surface. For example, it may have a net-like structure or a plate-like structure with many holes (such as a perforated plate) that allows wind to easily pass through and reduces wind pressure.

[0031] The fall prevention member mounting fixtures 13 for the fall prevention member 2 to the support pole 3 are provided on the top and bottom, and as shown in Figures 3(a) and (b), are integrally formed with a gripping portion 23 having a concave vertical cross section which grips the upper frame 16 and the lower frame 17, respectively, and a support pole mounting portion 24 having a concave horizontal cross section. Note that, although the term "concave shape" is used in this specification, it is intended to include not only a concave shape, but also a shape in which the concave shape is upside down.

[0032] In the mounting structure in which the fall prevention member 2 is mounted to the pillars 3 at both lateral ends, as shown in FIG. 3(b), the upper and lower fall prevention member mounting fixtures 13 each have their gripping portions 23 which fit into and grip the upper and lower frames 16 and 17 of the fall prevention member 2, respectively, and their pillar mounting portions 24 are inserted through the pillars 3 and fixed with bolts 25.

[0033] A modified example of the mounting structure for mounting the fall prevention member 2 to the support pole 3 will be described with reference to Fig. 5. As shown in Fig. 5(a) and (b) facing downward and upward, respectively, the modified fall prevention member mounting fixture 14 is integrally formed with gripping parts 26 with concave vertical cross sections for gripping the upper frame 16 and the lower frame 17, respectively, and a support pole mounting part 27 with a rectangular horizontal cross section.

[0034] 5(c), a modified mounting structure for mounting the fall prevention member 2 to the support pole 3 has a configuration in which the gripping portion 26 of the fall prevention member mounting fixture 14 fits into and holds the upper frame 16 of the fall prevention member 2, and the support pole mounting portion 27 is inserted through the support pole 3 and fixed with a bolt 28. When mounting the lower frame 17 to the support pole 3, the mounting fixture 14 can be turned upside down, although this is not shown.

[0035] Figures 5(d) to (f) are oblique views showing the mounting fixtures 14 for the ends of the upper frame 16 and the lower frame 17 and their mounting structure. When viewed from the front, they are ┤-shaped rather than cross-shaped, but are basically the same as the configuration shown in Figure 5(c).

[0036] Depending on the longitudinal length of the balcony, two or more support pillars 3 are erected, and correspondingly, one or more fall prevention members 2 are also provided.

[0037] The support pillars 3 are made of square pipes or the like, and their length is slightly shorter than the height from the balcony floor 6 (or groove 71) to the ceiling 29. The support pillars 3 may be configured to abut against the ceiling 29 via a tension rod 63 (described later) (see the center support pillar 3 in Fig. 1), but may also be configured not to use the tension rod 63 (see the left support pillar 3 in Fig. 1).

[0038] As shown in Figures 1 and 2, the pillar support structure 7 that supports and reinforces the lower part of the pillar 3 on the balcony floor 6 (or groove 71) comprises a foot reinforcement piece 35 (see Figure 8(a)), a foot height adjustment piece 36 (see Figure 8(b)), a floor contact plate 37, and a double-sided adhesive tape 38. A small engagement protrusion 47 (see Figure 2) is formed facing upward on the floor contact plate 37.

[0039] 2, the foot reinforcement piece 35 is an L-shaped member in horizontal cross section that is long and thin in the vertical direction. It abuts against the lower part of the support pillar 3 and is fixed with bolts 40 to reinforce the lower part of the support pillar 3.

[0040] 2, the foot height adjustment piece 36 is an L-shaped member in horizontal cross section that is long and thin in the vertical direction, and its lower end is folded back horizontally to form a bottom portion 44. A small engagement hole 48 (see FIG. 2(b)) is formed in the bottom portion 44.

[0041] 2, the column support structure 7 for the column 3 is shown, in which the column 3 is erected, and the foot reinforcement piece 35 is abutted along its lower part and, as described above, is fixed with the bolt 40. Along this foot reinforcement piece 35, the foot height adjustment piece 36 is fixed with the bolt 45, as described above.

[0042] The foot height adjustment piece 36 abuts against the foot reinforcement piece 35, and its position in the height direction is adjusted and fixed with bolts 45 so that it comes into contact with the balcony floor 6 (or groove 71). The bottom 44 is then fixed to the surface of the balcony floor 6 (or groove 71) via abutment plate 37 and double-sided adhesive tape 38, supporting the support post 3 from below.

[0043] With the engaging protrusion 47 of the floor contact plate 37 fitted into the engaging hole 48 of the bottom 44 of the foot height adjustment piece 36, the foot height adjustment piece 36 is placed on the floor contact plate 37. As described above, the floor contact plate 37 is adhered to the surface of the balcony floor 6 (or groove 71) via the double-sided adhesive tape 38 with strong adhesive power.

[0044] With this type of post support structure 7, the lower part of the post 3 is reinforced with a foot reinforcing piece 35, and furthermore, the foot height adjustment piece 36 is strongly adhered and fixed by the adhesive of the double-sided adhesive tape 38 via the floor contact plate 37 in accordance with the uneven surfaces of the balcony floor 6, groove 8, etc. Therefore, the foot of the post 3 is supported with great strength when standing on the balcony.

[0045] The post 3 crosses and is fixed to the handrail 8 of the existing balcony fence 9 at approximately the middle of its height, as shown in Figures 4(a) to (c). The fixing structure 50 that fixes the post 3 to the handrail 8 includes a post fixing tool 51, a pressing plate 52, and rubber inserts 57, 58, etc., as shown in Figures 4(b) and (c).

[0046] The pillar fixing device 51 is integrally composed of a pillar fixing portion 53 consisting of a tubular portion with a square-shaped horizontal cross section on the pillar 3 side, a handrail fixing portion 54 with a concave-shaped vertical cross section on the handrail 8 side, and left and right protrusion portions 55 that protrude on both sides of the handrail 8 in the longitudinal direction.

[0047] In the fixing structure 50 for fixing the post 3 to the handrail 8, the post fixing device 51 has the post 3 inserted vertically through its post fixing part 53, and the post 3 is fixed from the left and right sides with bolts 56. The handrail fixing part 54 is fitted over the handrail 8 from above with rubber interposition 57 on its inner and upper surfaces, and a pressing plate 52 is abutted against the inner surface of the handrail 8 with rubber interposition 58 interposed therebetween.

[0048] The bolts 59 screwed into the left and right overhangs 55 of the handrail fixing device 12 are screwed in, and the pressure plate 52 is pressed against the handrail 8 via the rubber interposition 58. This causes the handrail 8 to be pressed and clamped between the handrail fixing part 54 and the pressure plate 52 via the rubber interposition 58, and the post fixing device 51 is fixed to the handrail 8. This allows the post 3 to be firmly fixed to the handrail 8.

[0049] A modified example of the fixing structure 50 for fixing the post 3 to the handrail 8 will be described with reference to Figures 6(a) and (b). The post fixing device 100, which is a modified example of the fixing structure 50, comprises a handrail fixing part 101 having a concave-shaped vertical cross section, a pressing plate 102, and an intermediate rubber 103.

[0050] In a modified example of the fixing structure 50 for fixing the post 3 to the handrail 8, the post fixing device 100 has its handrail fixing part 101 placed over the handrail 8 from above with a rubber interposition 103 interposed between it and the post 3, as shown in Figures 6(a) and (b), and a pressure plate 102 is further abutted against the inner surface of the handrail 8 with the rubber interposition 103 interposed between it and the post 3.

[0051] Then, the bolt 104 with the nut 105 screwed in is passed through the insertion hole 106 formed in the support 3 and screwed into the screw hole 108 formed in the inner wall 107 of the concave-shaped handrail fixing part 101, and further, the tip of the bolt presses the pressing plate 102 against the handrail 8 via the intermediate rubber 103. Then, the nut 105 is tightened so that it abuts against the inner surface of the support 3.

[0052] As a result, the handrail 8 is pressed and clamped between the handrail fixing part 101 and the pressing plate 102 via the intermediate rubber 103, and the handrail fixing part 101 is fixed to the handrail 8. This allows the support post 3 to be firmly fixed to the handrail 8 with the simple fixing structure 50.

[0053] The pillar 3 may be at a height that does not reach the balcony ceiling 29 (see the pillar 3 on the left side of Figure 1), but the upper end of the pillar 3 may be configured to abut against the balcony ceiling 29 via a tension rod 63 (the pillar 3 in the center of Figure 1, see Figure 3(a)).

[0054] 3(a) and (c), the configuration via the tension rod 63 is specifically such that a screw hole 67 (such as a configuration in which a square pillar having a screw hole 67 is fixed inside the pillar 3) is formed in the upper end of the pillar 3, and the screw portion 64 of the tension rod 63 is screwed into this screw hole 67. Then, the handle 65 of the tension rod 63 is rotated, and the abutment body 69 provided at the upper part of the tension rod 63 is pressed against the ceiling 29 via the double-sided tape 68 to fix it.

[0055] With this configuration, the tension rod 63 extends and retracts vertically from the support 3. By moving the tension rod 53 upward and pressing the abutment body 69 at its upper end toward the ceiling 29, it becomes possible to firmly erect and fix the support 3 to the balcony floor 6 (or groove 71) and ceiling 29.

[0056] The fall prevention device 1 having the above-mentioned configuration has the pillar 3, at its lower end, whose height is adjusted by the foot height adjustment piece 36 via the foot reinforcement piece 35, and is supported in contact with the surface of the balcony floor 6 (or groove 71), and is firmly fixed to the handrail 8 by the handrail fixing device 12 at approximately the center of its height so that it stands up.

[0057] Furthermore, if the upper end of the support pillar 3 is configured to abut against the balcony ceiling 29 via a tension rod 63, it can be made to stand with greater strength, and the collapse of the support pillar 3 and the resulting fall prevention member 2 can be prevented from falling even in strong winds or earthquakes.

[0058] Example 2 A second embodiment of the fall prevention device 1 according to the present invention will be described with reference to Figures 7 and 8. The second embodiment has substantially the same overall configuration as the first embodiment, but the pillar support structure 70 of the pillar 3 that supports and reinforces the lower part of the pillar 3 on the balcony floor 6 (or groove 71) is partially different from the pillar support structure 7 of the first embodiment.

[0059] In the second embodiment, the description will be centered on different configurations and will not include descriptions of configurations common to the first embodiment. Note that in the second embodiment, the same reference numerals are used to designate configurations common to the first embodiment.

[0060] In the pillar support structure 70 of the pillar 3 of the second embodiment, as shown in Figures 7 and 8, a foot reinforcement piece 35 (see Figure 8(a)) and a foot height adjustment piece 36 (see Figure 8(b)) having the same configuration as in the first embodiment are used.

[0061] That is, as shown in Figures 7(a), (c) and 8(d), the support pillar 3 is erected, and a foot reinforcement piece 35 is abutted along its lower part and fixed with a bolt 40. A foot height adjustment piece 36 is abutted along this foot reinforcement piece 35 and fixed with a bolt 45.

[0062] The horizontally folded bottom portion 44 formed at the lower end of the foot height adjustment piece 36 is abutted against and placed on the balcony floor 6 (or groove 71).

[0063] The second embodiment is characterized by a configuration in which a pair of inner and outer clamping pieces 75, 76 are provided to clamp the support rod 10 of an existing balcony fence 9 from the front and back using left and right bolts 74, as shown in Fig. 7(b). The inner clamping piece 75 is integrally formed with a fixing piece 77 that extends inward from its midpoint.

[0064] In the column support structure 70 for the column 3 of the second embodiment, as shown in Figs. 7(b) and 8(d), the fixing piece 77 of the inner clamping piece 75 abuts against the side surface of the column 3 and is fixed by a bolt 78.

[0065] The configuration in which foot reinforcement piece 35 is fixed to the inner surface of support pillar 3 with bolt 40 and foot height adjustment piece 35 is further fixed to the side of foot reinforcement piece 35 with bolt 45 is the same as the configuration shown in Figure 2 of Example 1.

[0066] With this type of pillar support structure 70, the pillar 3 is fixed laterally to the support rod 10 of the existing balcony fence 9 via a pair of clamping pieces 75, 76 and the fixing piece 77 of the clamping piece 75 (see Figure 7(b)), and its lower part is further supported from the inside by the foot reinforcement piece 35 and the foot height adjustment piece 35, allowing it to stand firmly.

[0067] Example 3 A third embodiment of the fall prevention device 1 according to the present invention will be described with reference to Fig. 9 to Fig. 11. The third embodiment is substantially the same as the first embodiment, but the pillar support structure 80 that supports and reinforces the lower part of the pillar 3 on the balcony floor 6 (or groove 71) is partially different from the pillar support structure 7 of the first embodiment.

[0068] In the third embodiment, the description will be centered on different configurations and will not include descriptions of configurations common to the first embodiment. Note that in the third embodiment, the same reference numerals will be used to designate configurations common to the first embodiment.

[0069] In the pillar support structure 80 of the pillar 3 of the third embodiment, as shown in Figures 9 to 11, a foot reinforcement piece 35 (see Figure 8(a)) and a foot height adjustment piece 36 (see Figure 8(b)) having the same configuration as in the first embodiment are used.

[0070] That is, as shown in Figures 9(a), (b), 10(a), (c), and 11(a), the support pillar 3 is erected, and a foot reinforcement piece 35 is abutted along its lower part and fixed with a bolt 40. A foot height adjustment piece 36 abuts along this foot reinforcement piece 35 and is fixed with a bolt 45.

[0071] The horizontally folded bottom portion 44 formed at the lower end of the foot height adjustment piece 36 is abutted against and placed on the balcony floor 6 (or groove 71).

[0072] A pillar support structure 80 of the third embodiment is characterized in that a pillar 3 is fixed to a concrete protruding edge portion 96 of a balcony floor 6 by a foot fixing device 81 as shown in Figs.

[0073] Whether or not a concrete raised edge 96 is present depends on the structure of the balcony, but if it is present, the concrete raised edge 96 is formed along the outer edge of the balcony, with a raised vertical cross-section on the balcony floor 6 (or groove 71) (see Figures 9 to 11), and the lower end of the existing balcony support rod 72 is usually fixed to this and stands upright.

[0074] As shown in Figures 10(a), (b) and 11, the foot fixing device 81 comprises a fastening piece 82 having a concave-shaped vertical cross section, an auxiliary piece 83 having a crank-shaped vertical cross section, and an L-shaped metal fitting 85 that is L-shaped when viewed horizontally. A long hole (see Figure 11(a)) for position adjustment is formed horizontally in the L-shaped metal fitting 85.
