The legs 14 are arranged in the space 18 so that the side surfaces formed in parallel with the mounting portions 15 of the legs 14 face the respective end surfaces 17. Each of the end faces 17 is provided with a horizontal guide groove 19 extending from the outer side to the inner side of the frame body 13 (hereinafter referred to as a horizontal direction), for example, from the outer side surface of the outer frame member 12 to the inner side surface. At the same time, each of the side surfaces of the mounting portion 15 is formed with a ridge 20 that can be inserted into the guide groove 19 from the outside.
The guide grooves 19 and the ridges 20 are engaged with each other.
The engaged state is shown in FIG. 2, and the guide groove 19 formed in the end surface 17 and the ridge 20 formed in the mounting portion 15 are shown in FIGS. 3 and 4, respectively. As a fixing means for attaching the leg 14 to the frame body 13, the inner plate thickness surface 21 of the attaching portion 15 is
A female screw portion 22 such as a nut is embedded in the female screw 22, and a male screw portion 24 such as a bolt penetrating a hole 23 formed in the fixture 16 is screwed to the female screw 22, and the screw is inserted through the fixture 16. The legs 14 and the frame 13 are fixed. A male screw portion 24 is embedded in the mounting portion 15 instead of the female screw portion 22, and the male screw portion 24 is provided so that the tip side of the male screw portion 24 penetrates the hole 23 of the mounting tool 16. May be screwed from the inside of the fixture 16 with a female screw.

Further, although the ridges 20 formed on the legs 14 are continuous, they may be discontinuous when the mounting angle of the legs with respect to the frame 13 can be kept constant. Saha

By arranging the legs in the space 18 formed between the parallel end faces and embedding a part of the fixing means for fixing the frame 13 and the legs 14 in the legs 14, the legs 14 around the part of the fixing means are thin. Even if it becomes, since the guide groove 19 and the ridge 20 which are engaged with each other keep the attachment angle of the leg with respect to the frame body constant, even when an external force is applied to the leg 14, The external force is less likely to be applied to a part of the fixing means provided, and it is possible to prevent the thin portion of the leg 14 from being destroyed by a part of the fixing means. Also, the ridges 20 that can be formed to the full width of the guide groove 19 and the leg 14 that engage with each other.
Are formed so as to be directed from the outer side surface of the frame body 13 toward the inner side surface thereof, so that in the engagement completed state arranged in the space 18 formed between the end surfaces of the outer frame members 12, the frame is The legs 14 are temporarily fixed to the body 13 due to its own weight and vibration so as not to fall easily, and the frame body 13 is fixed by the fixing means.
It is possible to easily fix the legs 14 and the legs 14 and to eliminate the risk of the legs 14 falling off the frame 13 from falling.

Effects of the Invention As described above, the mounting device for the goose legs according to the present invention is formed in the direction from the outer surface to the inner surface of the frame body formed on the end surfaces of the outer frame members located at the corners of the frame body facing each other. The guide grooves extending in the same direction as the guide grooves formed in the mounting portions of the legs are engaged with the facing guide grooves, and the guide grooves are slid to slide in the spaces formed between the end faces of the outer frame members facing each other. Since it is arranged, the legs are temporarily fixed to the frame body so as not to drop easily due to its own weight or vibration, and the work of fixing the frame body and the legs by the fixing means is easy and the legs separated from the frame body It can eliminate the danger of falling. Further, by embedding a part of the fixing means for fixing the frame body and the leg in the leg, even if the periphery of the part of the embedded fixing means becomes thin, the guide grooves engaging with each other. Since the mounting angle of the leg with respect to the frame is kept constant by the ridge and the ridge, even when an external force is applied to the leg, it is difficult to apply the external force to a part of the fixing means provided on the leg, and the leg is thin-walled. Prevents the part from being destroyed by part of the fixing means
