Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a fall prevention device for a balcony that is attached to the fence of a balcony of a high-rise building or the like to prevent people or objects from falling from the balcony.

[Conventional technology]

Conventionally, as this type of balcony fall prevention device, one shown in Japanese Utility Model Application Publication No. 54-80300 is known.

In this device, a long bowl-shaped basket is attached to the load part of the gravity load switch, a hanging fixture is provided to the support part of the gravity load switch, and the alarm is activated by the gravity load switch. It is something.

[The problem that the idea aims to solve]

However, in the above conventional example, (a) Since the hook of the hanging fixture is hooked onto the vertical bar of the fence, the vertical bar could not withstand the load of a falling child, etc. and would break, causing the basket to fall into place. There is a risk that infants, etc. who were saved by containment may fall.

(b) In addition, since there is no handle or similar between the basket and the top of the fence, there is a new problem such as the possibility that the stored infant, etc. may fall out of the basket due to the acceleration caused by falling. It was hot.

This idea overcomes these drawbacks with a simple structure.
It is an attempt to eliminate everything.

[Means to solve the problem]

In order to solve the above problems, this invention consists of two or more overhang frames on which net members are stretched, and a substantially V-shaped support frame connected between the front end and the rear end of each overhang frame, The front and rear ends of each overhanging frame are stretched and bent upward, and the rear end straddles the lower horizontal bar of the fence upward from below, while the support frame extends halfway to the upper horizontal bar of the fence. straddle the support frame downward, and then the front end of the overhang frame and one end of the support frame,
The rear end of the overhanging frame and the other end of the support frame are each removably connected by a connecting member such as a long nut.

[Embodiment] An embodiment of this invention will be described below with reference to FIGS. 1 to 5.

Reference numeral 1 denotes a plurality of overhang frames (two in this embodiment) extending from the lower horizontal beam 3 of the balcony fence 2 to the outside of the fence 2 at a predetermined interval, and the front part of the overhang frames 1 is directed upward. The rear part is bent substantially vertically upward, and threaded parts 1a and 1b are formed at the tips, respectively, and horizontal bars 1c and 1d, which also serve as reinforcement, are connected near the front and rear ends.

Reference numeral 5 denotes a substantially V-shaped support frame which is connected to both the front and rear ends of the overhang frame 1 and fixed to the upper horizontal beam 4 of the fence 2 in the middle so as to straddle it downward from above. Threaded portions 5a and 5b having opposite threads to the threaded portions 1a and 1b formed at both the front and rear ends of the overhang frame 1 are formed at both ends of the overhang frame 1, and the threaded portion 5a at one end and the overhang frame The overhang frame 1 and the support frame 5 are connected by abutting the threaded part 1a of one end and the threaded part 5b of the other end and the threaded part 1b, respectively, and removably connecting them with a connecting member 6 such as a long nut. Join.

Various methods can be considered for fixing the overhang frame 1 and the support frame 5 to the fence 2, but in this embodiment, the bent part 7 of the support frame 5 is straddled over the upper horizontal beam 4 of the fence 2, and The bent portion 7 is fixed by a fixing member 8 consisting of a pair of substantially 7-shaped fasteners 9 and 91, as shown in FIG. 5, by tightening bolts 10 and nuts 11.

Then, the ends of the support frame 5 and the overhang frame 1 are butted against each other as described above and connected by the connecting member 6, and then the rear bent part of the overhang frame 1 is placed astride the lower horizontal beam 3. It is tightened and fixed by the same member as the fixing member 8.

A net member 12 is provided between the overhang frames 1...1.
It is made by stretching.

Note that the configurations shown in FIGS. 6 and 7 can also be implemented. This thing consists of the rear end of the overhang frame 1 and the support frame 5.
is integrally formed with the right side portion 5c, and
The front end of the overhang frame 1 is bent upward and inward into a substantially U-shape, and the upper end of the right side portion 5c is bent inward of the fence 2 to correspond to the cross-sectional shape of the upper horizontal beam 4. The bent portion 18 is hooked onto the upper horizontal beam 4 of the fence 2.

An oblique side portion 5d of a support frame 5 made of an inclined plate is fixed to the upper portion of the straight side portion 5c and the upper side 13 of the U-shaped portion of the overhang frame 1 with bolts 14 and nuts 15.

Note that 16 and 17 are the bent portions 1 of the right side portion 5c.
8 to the upper horizontal beam 4 of the fence 2. 19 is a net stop.

For example, attach the overhang frame 1 and the support frame 5 to 3 of the fence 2
A net member 12 is stretched between the overhang frames 1...1. 20 is the net member 1
This is a core metal attached to the edge of 2.

In this case, the fixing member 8 is not necessary, and a part of the end of the net member 12 is secured to the net stop 19.
Since it is secured to the overhang frame 1, it is easy to tension it, does not easily come off from the overhang frame 1, and does not shift outward from the tip or rear end of the overhang frame 1. Further, the core bars 20, 20 attached to the edges of the net member 12 prevent the edges from loosening and also provide a reinforcing effect.

Furthermore, the configurations shown in FIGS. 8 and 9 can also be implemented. In this structure, the overhang frame 1, the right side part 5c, and the oblique side part 5d of the support frame 5 are formed separately, and the rear end of the overhang frame 1, the right side part 5c, and the right side part 5c are formed separately. An intermediate member 2 whose upper end portion and the upper end portion of the oblique side portion 5d are externally fitted onto the lower horizontal beam 3 and the upper horizontal beam 4.
1 and 21 with bolts 22 and nuts 23 (described later), and the lower end of the oblique side 5d and the front end of the overhang frame 1 are connected with bolts 14 and nuts 15 in the same manner as in FIGS. 6 and 7. That's what happens.

In this case, the intermediate member 21 is bent into a substantially U-shape as shown in FIG. 8 using a hinge at the bent portion according to the cross-sectional shape of the upper horizontal bar 4 and the lower horizontal bar 3 of the fence 2. , or approximately U (not shown)
A letter-shaped one is used. This intermediate member 21 has screw insertion holes at a plurality of locations extending from the bent portion to the end, and nuts 23 are fixed inside each hole.

The overhang frame 1 has a leading end bent upward into a substantially U-shape, and a rear end bent upward at a substantially right angle. and,
By making the screw insertion holes opened near the rear end of the overhanging frame 1 correspond to the required screw insertion holes of the intermediate member 21 externally fitted on the lower horizontal crosspiece 3, and by screwing the bolts 22 into the nuts 23, the overhanging frame can be assembled. 1 and the intermediate member 21 are connected. The straight side portion 5c of the support frame 5 is connected at its upper and lower ends to the intermediate members 21, 21 externally fitted onto the upper horizontal beam 4 and the lower horizontal beam 3 in the same manner as described above. Note that the same reference numerals as above indicate the same structure.

In this case, in addition to substantially the same advantages as in the case of the above configuration, the intermediate members 21, 21 and the right side portion 5
c and the oblique side portion 5d can be changed by selecting the screw insertion hole through which the bolt 22 is inserted,
Therefore, since the distance between the intermediate members 21 and 21 can be changed, the right side portion 5c can be made to have an appropriate length according to the height of the fence 2, and the overhang frame 1 and the support frame 5 can be attached to the fence 2. Can be installed. Alternatively, the overhang frame may be attached in an inclined state so that the leading end is higher than the rear end.

[Effect of idea]

According to this idea, (1) Both the front and rear ends of each overhang frame are stretched and bent upward, and the rear end straddles the lower horizontal crosspiece of the fence upward from the bottom, while the support frame is straddles the upper horizontal beam of the fence downward from the top, and the ends of the overhanging frame and the ends of the support frame are connected with a connecting member such as a long nut,
Since the overhang frame and support frame are straddled by the upper and lower horizontal rungs, which have the highest strength among fences, the load of infants, etc. stored in the net section causes the upper rung, lower rung, and overhang frame to straddle each other. Also, since the support frame can be prevented from being broken, the net member will not fall.

(2) The support frame not only serves as a handle for an infant, etc. that falls and is held, but also as a guard member to prevent the infant, etc., from falling, and is a safe structure that prevents the infant, etc. contained therein from slipping off the net member. We can provide fall prevention equipment for balconies.

(3) Since the connecting member removably connects the front end of the overhang frame to one end of the support frame, and the rear end of the overhang frame to the other end of the support frame, the upper horizontal beam of the fence and By appropriately selecting a support frame according to the distance from the lower horizontal beam, the connection length with the overhang frame can be adjusted as appropriate. In addition, it has many advantages such as an extremely simple structure.
