Description

Portable folding type motion bed {Portable folding type motion bed}

The present invention relates to a portable folding motion bed, and more specifically, to a portable folding motion bed that is lightweight and has a folding function, thereby enabling portability and movement and convenient storage.

In general, a motion bed is composed of two separate mattresses on one frame, and the angle of the bed can be adjusted as needed. The actuator mounted on the lower part of the frame operates to adjust the angle of the mattress where the upper and lower body come into contact as desired, thereby stably supporting the body and reducing the pressure applied to each part of the body, thereby helping the user to sleep comfortably and rest well.

The above motion bed was previously applied mainly to medical beds for the convenience of patients with limited movement, but as interest in health increased and living standards improved, investment in health expanded, and it developed into a form of home bed. Recently, the demand for home motion beds has increased significantly, and accordingly, development of motion beds with various functions is also continuously underway.

However, although the convenience and stability of conventional motion beds have been greatly improved, most of them are installed once in a fixed location and used continuously, and since the frame is mainly made of heavy materials such as wood or steel, it is not only inconvenient to move to another location after installation, but also difficult to carry.

As shown in Fig. 5, the leg portion (50) is preferably formed by displacing the leg (51) installed at the rear end of the upper frame (11) and the leg (51') installed at the front end of the lower frame (13) in a left-right direction (up-down direction in the drawing) so that interference between the adjacent legs (51, 51') does not occur when folding the upper frame unit (A) and the lower frame unit (C) by means of a folding means.

In addition, the leg portion (50) can be completely separated from the front and rear ends of the upper frame and the front and rear ends of the lower frame as shown in FIG. 6, thereby eliminating interference by the leg portion when folding the frame units.

Additionally, a leg support reinforcing piece (51) is provided on the inner side of each corner of the main frame part (10) to support each leg part (50).

FIG. 5 is a side view showing a state in which a motion bed is folded using a folding means according to the first embodiment of the present invention, with the driving unit and leg unit omitted. FIG. 6 is an exploded perspective view of the folding means of FIG. 5, and FIG. 7 is an operating state diagram of the folding means of FIG. 5.

According to the drawing, the folding means (60A) is installed on the left and right ends of the central frame (12) of the main frame section to fold and unfold the upper frame unit (A) and the lower frame unit (C) with each other, and is composed of a first folding member (61) and a second folding member (62), which are formed in a shape symmetrical to each other.

The first folding member (61) is mounted on each end of the side vertical bars (122, 123) of the central frame (12), and is composed of a first insertion groove (611) into which the end of the side vertical bar is inserted, a first hinge projection (612) that is formed by protruding and extending in the opposite direction to the first insertion groove, and a first hinge groove (613) that is formed in a step shape on the first hinge projection. The first insertion groove (611) is formed with a plurality of first insertion fixing holes (611a) so that it is fixedly fastened to the side vertical bars (122, 123).

The second folding member (62) is mounted on the rear end of the first right side bar (113) of the upper frame and the front end of the second right side bar (133) of the lower frame, respectively, corresponding to the first folding member, and is composed of a second insertion groove (621) into which the rear end of the first right side bar (113) (the front end of the second right side bar (133)) is inserted, a second hinge protrusion (622) that is formed to protrude and extend in the opposite direction to the second insertion groove and is coupled to the first hinge groove (613), and a second hinge groove (623) that is formed in a stepped manner on the second hinge protrusion and is coupled to the first hinge protrusion (612). The second insertion groove (621) is formed with a plurality of second insertion fixing holes (621a) so as to be fixedly fastened to the first and second right side bars (113, 133).

The first and second hinge projections (612, 622) above are formed with joint holes (612a, 622a) respectively and are connected by a hinge joint (65), and the upper frame unit and the lower frame unit are folded by bending twice around each of the hinge joints (65).

At this time, as shown in Fig. 8, the first and second hinge projections (612, 622) are formed with a curved shape at the lower corner portion to form vertical and horizontal straight portions (L1, L2) and a curved portion (R), and the first and second hinge grooves (613, 623) are provided with a step portion (614, 624) whose wall surface connected to the first and second hinge projections is a straight shape, so that when the upper frame unit and the lower frame unit are folded by the first and second folding members, the curved portions (R) of the first and second hinge projections (612, 622) are folded while rotating along the step portions in contact with the step portions (624, 614) of the second and first hinge grooves, respectively, and when the folding angle is 90°, the straight portions (L2) of the first and second hinge projections are engaged with the lower side of the step portions (624, 614) of the second and first hinge grooves, so that no more Folding is limited to prevent it from collapsing.

On the other hand, when the angle between the upper frame unit and the lower frame unit is 180° during unfolding, the straight portion (L1) of the first and second hinge projections (612, 622) engages with the upper portion of the step portion (614, 624) of the second and first hinge grooves (612, 613), thereby restricting unfolding so that it cannot unfold any further.

In this way, in the folding means (60A), the first folding member (61) and the second folding member (62) are formed symmetrically in a diagonal direction without distinction between left and right, and the hinge projections intersect each other to form a connection, and further, a vertical straight surface, a curved surface, and a horizontal straight surface are formed at the ends of the hinge projections of the first and second folding members, and a step portion is provided at a corresponding portion, and when the vertical straight surface of the hinge projection on the first folding member is in contact with the step portion on the second folding member, when the first and second folding members are folded, when the curved surface of the hinge projection on the first folding member reaches the end point, the folding and unfolding are naturally stopped as the horizontal straight surface engages with the step portion (for example, the step portion of the hinge groove portion).

In addition, the width of the space formed between the upper frame unit and the lower frame unit when they are folded must be secured to a level where the lower components do not touch each other.

Figure 8 is a second embodiment of a folding means according to the present invention.

The folding means (60B) is installed on both ends of the central frame (12) of the main frame section to fold and unfold the upper frame unit (A) and the lower frame unit (C) to each other, and is composed of a third folding member (63) and a fourth folding member (64), which are formed in a shape symmetrical to each other.

The third folding member (63) is mounted on each of the front and rear ends of the side vertical bars (122, 123) of the central frame (12), and is composed of a third insertion groove (631) inserted into the end of the side vertical bar, a third hinge projection (632) extending in the opposite direction from the center of the first insertion groove, and a joining groove (633) formed in a step shape on both sides of the third hinge projection to which a joining support part to be described later is joined. The third insertion groove (631) is formed with a plurality of third insertion fixing holes (631a) so that it can be fixedly fastened to the side vertical bars (122, 123).

At this time, the third hinge protrusion (632) is formed in a curved shape at the lower corner portion, just like the first and second hinge protrusions, so that vertical and horizontal straight portions (L1, L2) and a curved portion (R) are formed.

The fourth folding member (64) is formed in an H-shaped cross-section shape corresponding to the third folding member and is mounted on the rear end of the first right side bar (113) of the upper frame and the front end of the second right side bar (133) of the lower frame, respectively, and is composed of a fourth insertion groove (641) into which the rear end of the first right side bar (113) (the front end of the second right side bar (133)) is inserted, a fifth insertion groove (642) formed in the opposite direction to the fourth insertion groove and to which the third hinge projection (632) is coupled, and first and second joining support members (643, 644) formed to extend in the front-back direction on the outside of the fourth and fifth insertion grooves while being parallel to the upper and lower frames. The fourth insertion groove (641) is formed with a plurality of fourth insertion fixing holes (641a) so that it can be fixedly fastened to the first and second right side bars (113, 133).

The second joint support portions (644) formed to extend in the direction of the third folding member are each formed with a joint hole (644a) and connected by a hinge joint (65), and the upper frame unit and the lower frame unit are folded by bending twice around each of the hinge joints (65).
