DETAILED DESCRIPTION OF THE INVENTION
The drawings show an embodiment of the present invention. In FIGS. 1 to 5, reference numeral 1 denotes a rectangular tube-shaped metal pipe 1b, 1b made of, for example, steel or stainless steel, and both ends thereof are arranged at the corners. Is a frame that is fixed to the round cylindrical mounting pipes 1a, 1a,... By means of welding or the like, for example, so as to exhibit a substantially rectangular shape. A plurality of long and short beam members 2 made of a metal pipe made of stainless steel or the like are fixed by means such as welding. As shown in FIG. 3, a number of punch holes 3a, 3a,... Are provided between the frame members 2, 2,. Plates 3, 3... Are stretched by means such as welding. The reinforcing plates 3, 3... May be fixed to the frame body 1 or the beam member 2 using bolts, screws or the like. The mounting pipes 1a, 1a,... At the corners of the frame 1 have four leg parts 4, 4,. .. Are fixed in a detachable manner by mounting bolts 5 (only one is shown) that are fitted in 1a, 1a... And attached in the axial direction of the mounting pipes 1a, 1a. The means for attaching the leg 4 is shown in detail in FIG. According to the drawing, the mounting pipe 1a is provided with a recess 1c in the upper portion, and a mounting plate 1d is welded thereto, and the mounting plate 4b welded to the upper end of the leg portion 4 with the bolt 5 through the mounting plate 1d. Is fixed.
[0011]
A pair of mounting pipes 6 and 6 are fixed to the central part of the beam member 2 by means of welding or the like at a predetermined interval, and a holding rod 7 made of, for example, steel or stainless steel is attached to the mounting pipes 6 and 6. , 7 are detachably attached to the upper ends thereof by means such as bolts. In addition, although the fixing means with respect to the beam member 2 of this holding rod 7 and 7 is the same as the attachment means of the leg part 4 mentioned above, it is not limited to this. For example, a male screw portion may be provided on the upper end side of the holding rod 7 and screwed to a female screw portion provided on the attachment pipes 6 and 6. Or you may make it fix with a volt | bolt from the radial direction of the attachment pipe 6. FIG. In short, the fixing method is not limited, and various known means may be used. The same applies to the leg 4. The catch bars 7 and 7 do not necessarily need to be grounded on the floor, but if grounded, there is an advantage that the pressure resistance of the infant desk can be increased. In addition, if there are two catch bars 7 and 7, usually there are about six infants at the infant desk, so that the number of people that can be caught in the event of an earthquake can be increased. It is not always necessary to have two. One or two or more can be arbitrarily selected according to the size of the desk. The rubber seats 4a and 7a with height adjustment are attached to the lower ends of the leg portion 4 and the holding rod 7, but this rubber seat may be fixed.
[0012]
Rollers 8 and 8 are attached to the lower end of one of the four legs 4 that is located on one side so as to be grounded when the infant desk is tilted. Reference numerals 8 a and 8 a denote covers that cover the rollers 8 and 8. In particular, as shown in FIG. 5, for example, a wooden top plate 10 is placed on the upper surface of the frame 1 or the beam member 2, and the top plate 10 is attached to the frame 1 or the beam member 2. 9 is detachably fixed to 9 via a bolt 9a.
[0013]
Therefore, in a nursery school or kindergarten, when an earthquake occurs during childcare in the nursery room, the child or the mother escapes under this infant desk and clings to the holding bar, so that even if it is in severe shaking, the body By preventing the child from jumping out from under the infant desk, the body and life can be secured by falling into the fallen object. Also, in the event of an earthquake where a building collapses and a ceiling or beam falls, the desk can withstand heavy fallen objects without being crushed, and the body and life of the children and nurseries who evacuated under the desk. It can protect.
[0014]
FIGS. 6 to 9 show another embodiment of the present invention. A frame 11 made of metal pipe and a long and short beam member 12 attached to the inside of the frame 11 are also shown in FIGS. And the point which has the reinforcement plate 13 made from metal provided with many punch holes 13a is the same as the thing of previous embodiment. However, it differs from that of the previous embodiment in that the leg 14 and the holding bar 15 are configured to be foldable.
[0015]
That is, the leg portions 14 are not independent one by one, but are formed of metal pipes so that each pair has a substantially U-shape, and can be folded to the frame body 11 via the mounting members 16, 16. Is attached. Reference numeral 17 denotes a stopper means for the leg portion 14. Each free end of a first stopper piece 17 a that is pivotally attached to the frame 11 by a pin 19 and a second stopper piece 17 b that is pivotally attached to the leg 14 by a pin 18. The springs 21 are stretched between the first stopper piece 17a and the second stopper piece 17b. Reference numeral 22 denotes a connecting rod of stopper means 17 for cooperating stopper pieces 17a, 17a provided on each pair of legs 14,14.
[0016]
The holding bars 15 and 15 are foldably attached to the beam member 12 via the attaching member 23, and the stopper means 24 and 24 are attached to the holding bars 15 and 15, respectively. A partial enlarged side sectional view thereof is shown in FIG. 9, but the structure thereof is the same as that of the stopper means 17 of the leg portion 14 except that there is no connecting rod, so that the description thereof is omitted. In addition, the attachment means and stopper means with respect to the frame 11 and the beam member 12 of the leg part 14 and the holding bar 15 are examples, and are not limited to those of the embodiments.
[0017]
Therefore, the stopper pieces 17a, 17b, 24a and 24b of the stopper means 17 and 24 are in an unfolded state when the leg portions 14 and the holding rod 15 are opened, and the stopper portions 17c, 17d and 24c are mutually expanded. , 24d do not fall down in the folding direction, and are pulled firmly by the stopper means 17, 24 so that they are firmly fixed in an upright state so as not to fall in the opposite direction. The springs 21 and 21 pull each other so that the stopper pieces 17a, 17b, 24a, and 24b are not naturally folded. When the connecting portion 22 is pushed when the leg portion 15 is folded, the first stopper piece 17a and the second stopper piece 17b are bent at the connection position of each other and bent, and the leg portion 14 is slightly tilted. The leg portion 14 can be folded by pushing it in the folding direction. When opening the folded leg portion 14, when the leg portion 14 is held and opened, the stopper pieces 17 a and 17 b of the stopper means 17 are unfolded to enable the leg portion 14 to be activated. As described above, the open leg 14 is fixed in the upright position. When each gripping bar 15 is folded, when one of the stopper pieces 24a, 24a of the stopper means 24, 24 is slightly pushed, each stopper piece 24a, 24b supports its connecting position against the traction force of the spring 25. Since the holding rod 15 is slightly tilted, it is pushed by hand to fold it. Other functions and operations are the same as those of the legs 14.
[0018]
In addition, 26 and 26 are receiving members of the infant desk on the upper side when the legs and the gripping bars of the infant desk are folded and stacked. It is made of synthetic resin, and if it is present, it has the advantage that it does not damage the top of the infant desk.
[0019]
