Description

[Technical Field]

[0001] The present invention relates to a fall prevention device that prevents infants and children from falling from verandas or balconies. The fall prevention device of the present invention can be used on both verandas and balconies, but here we will explain it in terms of a veranda as a representative application. [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 falls from balconies in high-rise apartment buildings, resulting in injuries and deaths.

[0003] BACKGROUND 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] Also, handrails for preventing climbing over are known, which consist of a rotating handrail that is installed concentrically with a support shaft or via a rotating bearing, and which rotates when an infant or child places their hand on the top of the fence, preventing the child from climbing over the fence (see Patent Documents 3 and 4).

[0006] Conventional fall prevention devices have not always had a simple structure for mounting the fall prevention wall, and they have a large number of parts, so the installation work is not necessarily easy.

[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 direct 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 prone to loosening or breaking.

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

[0009] The present invention aims to solve the above-mentioned conventional problems, and its object is to realize a fall prevention device with a simple structure with a small number of parts, which is easy to attach to a balcony fence, and which is configured to suppress rattling even when exposed to wind and rain, and which is not loosened or removed from the balcony fence, and which can maintain its attachment strength.

BEST MODE FOR CARRYING OUT THE INVENTION

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

[0022] In the description 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 considered to be the outside of the balcony (or simply the "outside"), and the width direction (longitudinal direction) along the balcony railing is considered to be the horizontal direction (left-right direction) of the balcony railing.

[0023] In addition, the front view refers to the view of the fall prevention device from inside the balcony (building side), and the side view refers to the view from the side of the balcony. [Example]

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

[0026] The support pillars 3 support both lateral ends of the fall prevention member 2, the support pillar support structure 7 supports and reinforces the lower part of the support 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 support pillars 3 (more specifically, parts that attach the upper frame 16 and lower frame 17 of the fall prevention member 2 to the support 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 railing as shown in Figures 10(a) and (c). Therefore, in this specification, it is referred to as the floor 6 (or groove 71) as described above, and in the drawings it is referred to 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 has at least a handrail 8 (upper horizontal rod) and a lower horizontal 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] As shown in Figure 1, the fall prevention member 2 is formed in the shape of a fence as a whole, and comprises an upper frame 16 and a lower frame 17 that are installed horizontally along the balcony, and a plurality 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] Although the fall prevention member 2 is fence-shaped in this embodiment, it may have other configurations that do not receive wind pressure over the entire surface. For example, it may have a mesh-like configuration or a plate-like configuration with many holes (such as a perforated plate) that allows wind to pass through easily 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 that 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 support pillar 3 at both lateral ends thereof, as shown in Figure 3(b), the upper and lower fall prevention member mounting fixtures 13 have their gripping portions 23 which fit into and hold the upper frame 16 and lower frame 17 of the fall prevention member 2, respectively, and their support pillar mounting portions 24 are inserted through the support pillar 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 Figs. 5(a) and 5(b) facing downward and upward, the modified fall prevention member mounting fixture 14 is integrally formed with a gripping portion 26 having a concave vertical cross section that grips the upper frame 16 and the lower frame 17, respectively, and a support pole mounting portion 27 having a rectangular horizontal cross section.

[0034] In a modified mounting structure for mounting the fall prevention member 2 to the support pole 3, as shown in Figure 5(c), the fall prevention member mounting fixture 14 has a gripping portion 26 that fits into and holds the upper frame 16 of the fall prevention member 2, and a support pole mounting portion 27 that passes through the support pole 3 and is 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 perspective 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] Two or more support posts 3 are erected depending on the longitudinal length of the balcony, and one or more fall prevention members 2 are also provided correspondingly.

[0037] The support pillars 3 are made of square pipes or the like, and are slightly shorter in length 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 tension rods 63 (described below) (see the center support pillar 3 in Figure 1), but they may also be configured without tension rods 63 (see the left support pillar 3 in Figure 1).

[0038] As shown in Figures 1 and 2, the pillar support structure 7, which 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 double-sided adhesive tape 38. A small engagement protrusion 47 (see Figure 2) is formed on the floor contact plate 37 facing upward.

[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 along the bottom of the support column 3 and is fixed with bolts 40, reinforcing the bottom of the support column 3.

[0040] As shown in Figure 2, the foot height adjustment piece 36 is an L-shaped member in horizontal cross section that is long and narrow in the vertical direction, with the lower end formed with a horizontally folded bottom 44. The bottom 44 has a small engagement hole 48 (see Figure 2(b)).

[0041] The support structure 7 for the support column 3 is shown in Figure 2, in which the support column 3 is erected, with the foot reinforcement piece 35 abutting along its lower part and fixed with the bolt 40 as described above. 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).Then, the bottom 44 is fixed to the surface of the balcony floor 6 (or groove 71) via an abutment plate 37 and double-sided adhesive tape 38, and supports the support post 3 from below.

[0043] The foot height adjustment piece 36 is placed on the floor contact plate 37 with the engagement protrusion 47 of the floor contact plate 37 fitted into the engagement hole 48 of the bottom 44 of the foot height adjustment piece 36. 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, which has strong adhesive power.

[0044] With this type of support structure 7, the lower part of the support 3 is reinforced with foot reinforcing pieces 35, and furthermore, foot height adjustment pieces 36 are used to strongly adhere and fix the support to the uneven surfaces of the balcony floor 6, groove 8, etc., via floor contact plates 37 and double-sided adhesive tape 38. Therefore, the support 3 is supported at its base with great strength so that it stands upright on the balcony.

[0045] The post 3 is fixed to the existing balcony railing 9 at approximately the middle of its height by crossing it with the handrail 8, 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 pressure plate 52, and rubber inserts 57 and 58, as shown in Figures 4(b) and (c).

[0046] The support pillar fixing device 51 integrally comprises a support pillar fixing portion 53 consisting of a cylindrical portion with a square horizontal cross section on the support pillar 3 side, a handrail fixing portion 54 with a concave 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 portion 53, and the post 3 is fixed from the left and right sides with bolts 56. The handrail fixing portion 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 threaded into the left and right overhanging portions 55 of the handrail fixing device 12 are screwed in, and the pressure plate 52 is pressed against the handrail 8 via the interposed rubber 58. This presses and clamps the handrail 8 between the handrail fixing portion 54 and the pressure plate 52 via the interposed rubber 58, and the support post fixing device 51 is fixed to the handrail 8. This allows the support post 3 to be firmly fixed to the handrail 8.

[0049] A modified example of the fixing structure 50 for fixing the support pole 3 to the handrail 8 will be described with reference to Figures 6(a) and 6(b). equippedThe support pole fixing device 100 has a handrail fixing portion 101 having a concave vertical cross section. and a variant of the fixing structure 50 further comprises: It is provided with a pressing plate 102 and an interposed rubber 103 .

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

[0051] Then, bolt 104 with nut 105 screwed in is passed through insertion hole 106 formed in support 3 and screwed into screw hole 108 formed in inner wall 107 of concave-shaped handrail fixing part 101, and further, the tip of bolt 104 presses pressing plate 102 against handrail 8 via interposed rubber 103. Then, nut 105 is tightened so that it abuts against the inner surface of 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 interposed 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 a simple fixing structure 50.

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

[0054] 3(a) and 3(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 threaded 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 contact member 69 provided at the top of the tension rod 63 is pressed against the ceiling 29 via double-sided tape 68 to fix it.

[0055] With this configuration, the tension rod 63 extends and retracts vertically from the support post 3. By moving the tension rod 53 upward and pressing the abutment member 69 at its upper end toward the ceiling 29, the support post 3 can be firmly erected and fixed to the balcony floor 6 (or groove 71) and ceiling 29.

[0056] The fall prevention device 1 having the above-mentioned configuration has the support 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 by being in contact with the surface of the balcony floor 6 (or groove 71), and is firmly fixed to the handrail 8 at approximately the center of its height by the handrail fixing device 12 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 even in strong winds or strong 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 support structure 70 for the support 3, which supports and reinforces the lower part of the support 3 on the balcony floor 6 (or groove 71), is partially different from the support structure 7 of the first embodiment.

[0059] In the second embodiment, the description will be centered on the different configurations and will omit the description of the configurations common to the first embodiment. Note that in the second embodiment, the same reference numerals will be used to designate the configurations common to the first embodiment.

[0060] In the pillar support structure 70 of the pillar 3 of Example 2, 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 Example 1 are used.

[0061] 7(a), (c), and 8(d), the support column 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.

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

[0063] As shown in Figure 7(b), 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 the existing balcony fence 9 from the front and back using left and right bolts 74. The inner clamping piece 75 is integrally formed with a fixing piece 77 that extends inward from its midpoint.

[0064] In the support structure 70 for the support 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 support 3 and is fixed with a bolt 78.

[0065] The configuration in which a foot reinforcement piece 35 is fixed to the inner surface of the support 3 with a bolt 40, and a foot height adjustment piece 35 is further fixed to the side of the foot reinforcement piece 35 with a 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 Figures 9 to 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 the different configurations and will omit the description of the configurations common to the first embodiment. Note that in the third embodiment, the same reference numerals will be used for the configurations common to the first embodiment.

[0069] In the pillar support structure 80 of the pillar 3 of Example 3, 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 Example 1 are used.

[0070] 9(a), (b), 10(a), (c), and 11(a), the support column 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 placed in contact with the balcony floor 6 (or groove 71).

[0072] As shown in Figs. 9 to 11, the support structure 80 of the third embodiment is characterized by a configuration in which the support 3 is fixed to a raised edge portion 96 of the concrete of the balcony floor 6 by a foot fixing device 81.

[0073] Whether or not the 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 support rod 72 of the existing balcony 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 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. The L-shaped metal fitting 85 abuts against the side of the support 3 and is fixed with a bolt 89.

[0075] 10 and 11, in a column support structure 80, a fastening piece 82 is placed over a raised edge portion 96 of the concrete with a rubber interposition piece 87 interposed therebetween. An auxiliary piece 83 is placed on the inner end of the fastening piece 82, an L-shaped metal fitting 85 is abutted against an outer rising portion 84 of this auxiliary piece 83, and a bolt 88 is inserted into the long hole to adjust the lateral position and fix it in place.

[0076] As shown in Figures 10 and 11(b), the bolt 91 passes through a through hole 94 formed in the inner rising portion 90 of the auxiliary piece 83 and is further screwed into a screw hole 95 formed in the fastening piece 82, and its tip presses the abutment plate 86 against the convex edge portion 96 of the concrete via the intervening rubber 87.

[0077] Furthermore, a nut 93 is threaded onto the head side of the bolt 91, and by tightening this nut 93, the auxiliary piece 83 is pressed against the fastening piece 82 and fastened. This fixes the foot fixing device 81 to the raised edge portion 96 of the concrete, and as a result, the support 3 is fixed to the raised edge portion 96 of the concrete via the foot reinforcing piece 35 and the foot fixing device 81.

[0078] According to the pillar support structure 80 of Example 3 having such a configuration, the lower part of the pillar 3 is firmly fixed and supported to the raised edge portion 96 of the concrete via the foot reinforcement piece 35 and the foot fixing device 81, allowing it to stand upright.

[0079] The above describes the form for implementing the fall prevention device of the present invention based on the examples, but it goes without saying that the present invention is not limited to such examples, and there are various embodiments within the scope of the technical matters described in the claims.
