Description

  The present invention relates to a bed apparatus in which the upper body of a user can be held at a predetermined inclination angle using a headboard body.

  In the bed apparatus, a portion corresponding to the upper body of the user on the floor plate on which the mattress is placed is provided so that it can be raised and lowered, and the portion that can be raised and lowered can be driven up and down by a back raising mechanism. Bed devices are known. According to such an up-and-down bed device, the user can wake up on the mattress, so that the user can watch TV or read in that state, which is very convenient. It is.

  However, when a part of the floor board is raised, the mattress is bent along with the raising. Usually, the mattress is configured using a spring unit. As the spring constituting the spring unit, a coil spring or a continuous spring is used. In the continuous spring, a plurality of coil portions whose axes are parallel to each other by a single steel wire and connecting rods that connect the upper end and the lower end of adjacent coil portions are continuously formed.

  In any spring unit formed by using any spring, a frame line is provided at the peripheral edge of the upper and lower surfaces, and the peripheral part of the spring unit is reinforced by this frame line. Therefore, even when trying to bend a mattress using a spring unit having such a configuration by a raised floor board, the resistance at the time of bending is so great that it cannot be bent reliably or early. It was easy to damage.

  In particular, in a spring unit using a continuous spring, not only the frame line but also a connecting rod that connects adjacent coil parts becomes resistance during bending, so the bending resistance is significantly higher than that of a spring unit using a coil spring. That happened.

  Therefore, instead of raising the floor board and bending the mattress, a backrest body is provided on the front surface of the headboard body so that the backrest body can be rotated, and the backrest body can be held at a predetermined inclination angle. A bed apparatus has been proposed that allows a person to maintain a posture of raising the upper body on a mattress.

  Such a prior art is shown in Patent Document 1. That is, the bed apparatus disclosed in Patent Document 1 includes a headboard body. The headboard body has a main body, and one end of an arm is rotatably connected to the main body. A backrest is rotatably connected to the other end of the arm. And the said backrest can be hold | maintained in the state accommodated in the said main-body part, and the state inclined by the predetermined angle on the mattress.

Therefore, if the backrest is held at a predetermined angle on the mattress, the user can take a posture of raising the upper body by leaning on the backrest.

A stopper 33 is slidably provided on the case 32 by a spring (not shown) so that its tip is urged in a direction protruding from the lower end of the case 32. One end of the tip of the stopper 33 is an inclined surface and the other surface is a vertical surface.

  The case 32 is attached and fixed to the lower end of the other side surface of the second slip prevention member 12. As shown in FIG. 5, in the state where the mounting body 3 is not moved with respect to the frame 1, the vertical surface of the tip of the stopper 33 is engaged with the locking metal fitting 34 provided on the end surface of the frame 1. It is combined. Thereby, the above-mentioned mounting body 3 cannot move in the forward direction.

  In the state in which the stopper 33 is engaged with the frame 1, the movement of the mounting body 3 in the backward direction (headboard body 15 side) is caused by the second horizontal rail 7 hitting the second contact member 8. Be regulated. That is, the mounting body 3 does not move in either the front-rear direction when the stopper 33 is engaged with the frame 1.

  One end of a strap-like operation member 35 is connected to the rear end of the stopper 33. The other end portion of the operation member 35 is formed in a loop shape and led out to the upper surface of the mattress 9. When the operating member 35 is pulled, the stopper 33 slides against the urging force of the spring, and the tip of the stopper 33 is disengaged from the locking fitting 34 provided on the end surface of the frame 1. Thereby, the above-mentioned mounting body 3 becomes movable with respect to the frame 1.

  According to the bed apparatus having such a configuration, the cushion body 25 of the headboard body 15 is erected almost vertically as shown in FIGS. 1, 3 and 5, or the lower end as shown in FIGS. Can be used in any state of the inclined state in which the lens has moved forward.

  In a state where the cushion body 25 stands substantially vertically, the stopper 33 constituting the second stopper means is engaged with the end surface of the frame 1 as shown in FIG. 5, and the second horizontal rail 7 is in the second contact state. It is in contact with the member 8. As a result, the mounting body 3 on which the mattress 9 is mounted is positioned and held on the frame 1 so as not to move in any of the front and rear directions, so that the cushion body 25 is maintained in a substantially vertical state.

  The bed apparatus with the cushion body 25 in a vertical state can be used by a user sleeping on the mattress 9, raising his / her upper body on the mattress 9, and leaning on the cushion body 25 for reading. .

  When the user leans on the cushion body 25 in a state where the cushion body 25 is standing substantially vertically, the user is in a posture in which the upper body is raised substantially at a right angle. It may be easy.

  In such a case, the operation member 35 led out on the mattress 9 is pulled. As a result, the stopper 33 engaged with the engagement fitting 34 on the end face of the frame 1 moves in the upward direction against the biasing force of a spring (not shown), and the engagement with the engagement fitting 34 is released. If the user leans against the cushion body 25 with the head against the head cushion 21 and moves the mattress 9 forward by the buttocks so that the upper body falls backward, the user rests with the mattress 9. The body 3 moves forward on the frame 1.

  2 and 4 show a state in which the mounting body 3 has moved forward. When the mounting body 3 moves forward, as shown in FIG. 4, a cushion body whose lower end is rotatably connected by a hook member 29 to a holding member 24 provided at the other end in the longitudinal direction of the mounting body 3. 25 is interlocked and the lower end moves forward.

  When the lower end portion of the cushion body 25 moves forward, the link 23 rotates from the standing state shown in FIG. 5 in the lying down direction with the both end portions supported by the fixture 22 as fulcrums. That is, the link 23 rotates in the direction opposite to the cushion body 25.

  As a result, the cushion body 25 is lowered from the standing state while rotating in the lying down direction, and the upper end descends, as shown in FIG. 4, is inclined at a predetermined inclination angle, and is held in the inclined state by the link 23 and the holding member 24. . In this state, the first horizontal rail 5 comes into contact with the first contact member 6 and the mounting body 3 is prevented from moving further forward.

  Therefore, the user can lean on the tilted cushion body 25 to tilt the upper body backward and take a comfortable posture. That is, the cushion body 25 of the headboard body 15 can be used for reclining.

  The cushion body 25 inclined at a predetermined angle is held by a link 23 and a holding member 24. That is, the lower end of the cushion body 25 is not supported by being supported on the upper surface of the mattress 9 as in the prior art, and can be held in a state where the link 23 and the holding member 24 are inclined at a predetermined angle.

  Therefore, when the cushion body 25 is used while being tilted, the load of the user is not applied to the upper surface of the mattress 9 via the cushion body 25, so that the mattress 9 is not partially damaged at an early stage. Can do.

  Moreover, since the cushion body 25 is tilted in conjunction with the movement of the mounting body 3 and is held by the link 23 and the holding member 24 in a predetermined tilted state, even if the user leans against the cushion body 25, The tilted state does not move. That is, the cushion body 25 can be used in a stable state at a predetermined inclination angle.

  When the cushion body 25 is tilted, the user pulls the operation member 35 led to the upper surface side of the mattress 9 to remove the stopper 33 from the locking metal fitting 34 provided on the frame 1, and for example, a saddle portion or the like through the mattress 9. And a force for moving the mounting body 3 in the forward direction may be applied.

  That is, the user raises the upper body on the mattress 9, hits the head against the head cushion 21, and removes the stopper 33. In this state, if the lower half of the body is shifted forward, the above-described placement body 3 can be shifted forward together with the mattress 9. Therefore, when the cushion body 25 is tilted from the vertical state, the user can perform the operation without getting off the mattress 9, so that it is very easy to use and convenient.

  When returning the cushion body 25 from the inclined state to the vertical state, the mounting body 3 is moved in the backward direction. In that case, the user only has to descend from the mattress 9 and push the tip of the mattress 9 in the backward direction (headboard body 15 side).

  When the mounting body 3 is pushed and moved in the backward direction, the inclined surface at the tip of the stopper 33 hits the inner surface of the frame 1. As a result, the stopper 33 rises, gets over the upper end of the frame 1 and engages with the locking bracket 34. That is, in order to raise the cushion body 25 from the inclined state, the stopper 33 can be automatically engaged with the locking fitting 34 when the mounting body 3 is moved to the headboard body 15 side.

  When the cushion body 25 is inclined, the opening portions on both sides in the width direction of the cushion body 25 are covered with the cover 30. Therefore, when the cushion body 25 is tilted, the front surface of the fixed portion 18 constituting the headboard body 15 and the lower surface side of the cushion body 25 are not exposed, so that the appearance is very good.
