Claims

[Claims for Utility Model Registration] The leg body 2 is attached to the pivot shaft 44 attached to the leg attaching portion 26 at the corner of the upper frame 1 so as to be movable in a minute dimension in the longitudinal direction thereof, and the elastic member 75 This is a leg for a home kotatsu in which the leg body 2 is resiliently biased toward the proximal direction, and a protrusion 20 is provided upright on the proximal end surface portion 19 of the leg body 2, and the protrusion 20 is Concave groove 21 in the center of the upper end surface
At the same time, notches 22, 22 are formed on the left and right upper end edges of the protrusion 20, and further, the leg body 2
The first fitting piece 27 that fits into the groove 21 of the protrusion 20 and the leg body 2 are parallel to the top frame 1 in the unfolded state in which the first fitting piece 27 is perpendicular to the top frame 1. In the folded state, the groove 2 of the protrusion 20
1, and the protrusion 20.
The notches 22, 22 of the leg body 2 engage with each other and slide while being pressed by the resilient force of the resilient member 75, thereby causing rocking between the first and second fitting pieces 27, 28 of the leg body 2. A leg for a home kotatsu, characterized in that the leg attachment part 26 is provided with a pair of guide protrusions 40, 40 having a substantially quarter-arc inner edge part 39 for guiding movement.
