  FIG. 2 shows a horizontal deployment posture when the bed is used in which the front bed half 1 and the rear bed half 2 are deployed horizontally, and the state in which the safety cover 4 covers the pivot portion 3 in this bed horizontal deployment posture. This is shown in (a) of FIG. 5 and (a) to (c) of FIG. FIG. 3 shows a state in which the front bed half 1 and the rear bed half 2 are folded to be in a vertical posture, and the cover state of the safety cover 4 in the state in which the front bed half is folded in the vertical posture is shown. This is shown in (b) of FIG. 5 and (a) to (c) of FIG.

  That is, in the bed horizontal deployment posture in which the front and rear bed halves 1 and 2 are deployed horizontally, as can be seen from FIGS. 5 (a) and 6 (a) to 6 (c), the pivot of the front frame 5 can be seen. Is located at the upstream end of the guide grooves 21 and 22 in the inner and outer walls 18 and 19 of the safety cover 4, and the upper wall 20 of the safety cover 4 is on the upper end surface of the pivot bracket 9. Almost all of the pivoting portion 3 is covered in a state of almost abutting.

  When the front and rear bed halves 1 and 2 are folded from the horizontal deployment posture of the bed, the front and rear frames 5 and 7 rotate about the bolts 14 and 16 (pivot axis) of the pivot bracket 9 to Stand upright in a vertical position with the opposite end face facing up. Accordingly, the bolt 14 which is the pivot on the front frame 5 side slides from the upstream end of the guide grooves 21 and 22 and is positioned at the downstream end, and at the end opposite to the guide grooves 21 and 22 is safe. A pivot pin 24 pivoting the cover 4 to the end of the rear frame 7 is displaced above the pivot bracket 9, so that the safety cover 4 can be seen in FIGS. 5 (b) and 6 (a). As can be seen from (c), almost the entire pivoting portion 3 is covered in a state where the upper wall portion 20 is almost in contact with the opposed end surfaces of the front and rear frames 5 and 7 facing upward. That is, when the front and rear bed halves 1 and 2 are folded from the horizontal deployed posture and stood in the vertical posture, the safety cover 4 is displaced upward following the folding operation of the front and rear bed halves 1 and 2, It covers almost the entire landing portion 3.

  Further, when the front and rear bed halves 1 and 2 folded in the above-described manner and vertically deployed are deployed horizontally, the bolt 14 which is the pivot of the front frame 5 is moved from the downstream end of the guide grooves 21 and 22. Slide and move to the upstream end, and the safety cover 4 is displaced downward following the unfolding motion of the front and rear bed halves 1 and 2, and pivots as shown in FIGS. 6 (a) to (c). Covers almost the entire landing portion 3. In this way, when the front and rear bed halves 1 and 2 are deployed, the pivoting portion 3 is covered with the safety cover 4, so there is no risk of fingers or the like being sandwiched near the pivoting portion 3. Even when the front and rear bed halves 1 and 2 are deployed horizontally, the safety cover 4 is in a state in which the upper wall portion 20 is almost in contact with the upper end surface of the pivot bracket 9, and the pivot portion 3. Since there is no gap in the vicinity, it is safe without pinching sheets or the like.

  FIG. 8 shows another safety cover 34 according to the present invention. The safety cover 34 is substantially the same as the previous safety cover 4, and is substantially downwardly formed by an outer wall portion 18, an inner wall portion 19, and an upper wall portion 20 that connects the upper end portions of the inner and outer side wall portions 18, 19. A U-shaped cover is used to pivot one end of the side walls 18, 19 to the end of the front frame 5 with a pivot pin 24, and between the side walls 18, 19 and the pivot bracket 9. By installing a coil spring 32 that attracts the wall 20 to the pivot bracket 9 side, the safety cover 4 is displaced following the unfolding and folding operations of the front and rear bed halves 1 and 2 to cover the pivot 3. It is what I did.

  The safety cover 34 is formed with notches 33 in the side walls 18 and 19 for engaging both ends of the bolt 16 which is the pivot of the rear frame 7. Further, pivot pins 24 for pivotally attaching one end portions of the side wall portions 18 and 19 of the safety cover 34 to the end portions of the front frame 5 are provided at the respective upper end required portions of the inner and outer side plate portions 9 a and 9 b of the pivot bracket 9. A notch 9o for engaging the notch is formed.

Indicates the cover state of the safety cover 34 in a state where the front and rear bed halves 1 and 2 are folded to be in a vertical posture, and resists the urging force of the coil spring 32 for easy understanding of the internal structure. A state where the safety cover 34 is opened and rotated is indicated by a solid line.

  That is, in the bed horizontal deployment posture, the safety cover 34 covers almost the entire pivoting portion 3 with the upper wall portion 20 almost in contact with the upper end surface of the pivoting bracket 9. Thus, when the front and rear bed halves 1 and 2 are folded from the horizontal deployment posture of the bed, the front and rear frames 5 and 7 are rotated around the bolts 14 and 16 (axial axes) so that the front and rear frames 5 and 7 face each other. The safety cover 34 was erected in a vertical posture so that the end surface is upward, and the safety cover 34 was displaced upward in a parallel posture against the urging force of the coil spring 32, and the upper wall portion 20 thereof was upward. Almost all of the pivotally attached portion 3 is covered in a state where it is in contact with the opposing end surfaces of the front and rear frames 5 and 7. That is, when the front and rear bed halves 1 and 2 are folded from the horizontal deployed posture and stood in the vertical posture, the safety cover 34 is displaced upward following the folding operation of the front and rear bed halves 1 and 2. It covers almost the entire landing portion 3.

  In addition, when the front and rear bed halves 1 and 2 that are folded and raised in the vertical posture as described above are deployed horizontally, the safety cover 34 follows the unfolding operation of the front and rear bed halves 1 and 2 and is in a horizontal posture. As it moves downward, it covers almost the entire pivot part 3. Thus, when both the front and rear bed halves 1 and 2 are deployed, the pivotal attachment portion 3 is covered with the safety cover 4, so there is no risk of fingers being caught near the pivotal attachment portion 3, and both Even in the state where the bodies 1 and 2 are deployed horizontally, the upper wall portion 20 abuts on the upper end surface of the pivot bracket 9 and there is no gap in the vicinity of the pivot portion 3, so that no sheets or the like are sandwiched.

  In the safety cover 4 of the above-described embodiment, arc-shaped guide grooves 21 and 22 are provided on one end side of the side walls 18 and 19, and the pivot 14 on the front bed half body 1 side is provided in the guide grooves 21 and 22. Although engaged, guide grooves 21 and 22 may be formed on the other end side of the side wall portions 18 and 19 so that the pivot 16 on the rear bed half body 2 side is engaged therewith. What is necessary is just to pivotally attach the other end side of the side wall parts 18 and 19 to the front bed half body 1 side by the pivot 24. Further, in the safety cover 34 of the above-described embodiment, one end portion of the side wall portions 18 and 19 is pivotally attached to the front bed half body 1 side by the pivot 24, but the other end portion of the side wall portions 18 and 19 is pivoted to the rear bed half body. You may pivot on the two sides.
