Description

1. Field of the Invention

The present invention relates to an electric bed and, more particularly, to a foldable bottom bed structure of an electric bed.

2. Description of the Related Art

A conventional electric bed comprises a bottom bed structure that has a large volume and cannot be detached, thereby causing inconvenience to the user during storage, packaging and transportation of the electric bed. Another conventional electric bed comprises a bottom bed structure which includes a front bed bottom and a rear bed bottom. The front bed bottom is provided with a concave portion, and the rear bed bottom is provided with a convex portion inserted into the concave portion of the front bed bottom. Thus, when the convex portion the rear bed bottom is detached from the concave portion of the front bed bottom, the rear bed bottom is removed from of the front bed bottom, such that the bottom bed structure is disassembled to facilitate storage, packaging and transportation of the electric bed. However, the bottom bed structure includes an electric cylinder and a linkage located under the front bed bottom and the rear bed bottom respectively, such that the bottom bed structure is not assembled easily.

BRIEF SUMMARY OF THE INVENTION

2019100043 15 Jan 2019

The primary objective of the present invention is to provide a bottom bed structure that is folded easily and quickly.

In accordance with the present invention, there is provided a bottom bed structure comprising a front bed bottom, a rear bed bottom, two hinge mechanisms, and a plurality of stands. The front bed bottom includes a first frame and a first board. The first frame of the front bed bottom is provided with two first screw holes, two first mounting seats, and a second mounting seat.

The rear bed bottom includes a second frame and a second board. The second frame of the rear bed bottom is provided with two second screw holes, two third mounting seats, and a fourth mounting seat. Each of the two hinge mechanisms includes a pivot bracket and two bolts. The pivot bracket of each of the two hinge mechanisms is provided with two third screw holes formed in two ends thereof. Each of the stands is provided with a fastening bolt. In assembly, the pivot bracket of each of the two hinge mechanisms is located between the first frame of the front bed bottom and the second frame of the rear bed bottom. Then, the two bolts of each of the two hinge mechanisms extend through the two third screw holes of the pivot bracket, the two first screw holes of the first frame, and the second screw holes of the second frame respectively.

Then, the stands are screwed onto the two first mounting seats, the second mounting seat, the two third mounting seats, and the fourth mounting seat after the front bed bottom and the second frame of the rear bed bottom are expanded.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a bottom bed structure 1 of an electric bed in accordance with the preferred embodiment of the present invention comprises a front bed bottom 10, a rear bed bottom 11, two hinge mechanisms 12, and a plurality of stands 13.

The front bed bottom 10 includes a first frame 100 and a first board

101. The first frame 100 of the front bed bottom 10 is provided with two first screw holes 1000, two first mounting seats 1001, and a second mounting seat

1002. The rear bed bottom 11 includes a second frame 110 and a second board

111. The second frame 110 of the rear bed bottom 11 is provided with two second screw holes 1100, two third mounting seats 1101, and a fourth mounting seat 1102. The fourth mounting seat 1102 of the second frame 110 is located opposite to the second mounting seat 1002 of the first frame 100 to enhance the stability of the bottom bed structure 1. Each of the two hinge mechanisms 12 includes a pivot bracket 120 and two bolts 121. The pivot bracket 120 of each of the two hinge mechanisms 12 is provided with two third

2019100043 15 Jan 2019 screw holes 1200 formed in two ends thereof. Each of the stands 13 is provided with a fastening bolt.

In assembly, the front bed bottom 10 and the rear bed bottom 11 are juxtaposed to each other. Then, the pivot bracket 120 of each of the two hinge mechanisms 12 is located between the first frame 100 of the front bed bottom and the second frame 110 of the rear bed bottom 11. Then, the two bolts 121 of each of the two hinge mechanisms 12 extend through the two third screw holes 1200 of the pivot bracket 120, the two first screw holes 1000 of the first frame 100, and the second screw holes 1100 of the second frame 110 respectively, such that the pivot bracket 120 of each of the two hinge mechanisms 12 is pivotally connected with the first frame 100 of the front bed bottom 10 and the second frame 110 of the rear bed bottom 11 respectively.

Then, the stands 13 are screwed onto the two first mounting seats 1001, the second mounting seat 1002, the two third mounting seats 1101, and the fourth mounting seat 1102 by the fastening bolts.

Referring to FIG. 4 with reference to FIGS. 1-3, the stands 13 are removed from the first frame 100 of the front bed bottom 10 and the second frame 110 of the rear bed bottom 11. At this time, the first frame 100 of the front bed bottom 10 and the second frame 110 of the rear bed bottom 11 are connected pivotally by the pivot bracket 120 of each of the two hinge mechanisms 12, such that each of the two bolts 121 of each of the two hinge mechanisms 12 functions as a fulcrum. Thus, the front bed bottom 10 is

2019100043 15 Jan 2019 pivoted upward relative to the rear bed bottom 11, until a right angle (90°) is defined between the front bed bottom 10 and the rear bed bottom 11. At this time, each of the two hinge mechanisms 12 is perpendicular to the front bed bottom 10.

Referring to FIGS. 5 and 6 with reference to FIGS. 1-3, the front bed bottom 10 is pivoted toward the rear bed bottom 11, until the front bed bottom overlaps the rear bed bottom 11. At this time, each of the two hinge mechanisms 12 is perpendicular to the front bed bottom 10 and the rear bed bottom 11. Thus, the front bed bottom 10 overlaps the rear bed bottom 11, such that the bottom bed structure 1 is folded, to reduce the whole volume, thereby facilitating storage, packaging and transportation of the bottom bed structure 1.

Referring to FIG. 7 with reference to FIGS. 1-3, the front bed bottom is pivoted outward relative to the rear bed bottom 11, until the front bed bottom 10 is juxtaposed to the rear bed bottom 11, to expand the bottom bed structure 1. Then, the stands 13 are secured to the two first mounting seats

1001, the second mounting seat 1002, the two third mounting seats 1101, and the fourth mounting seat 1102 by the fastening bolts. Thus, the bottom bed structure 1 is used after expansion.

Accordingly, the front bed bottom 10 is pivoted to overlap the rear bed bottom 11, such that the bottom bed structure 1 is folded, to reduce the whole volume, thereby facilitating storage, packaging and transportation of the bottom bed structure 1, and thereby decreasing the cost of packaging. In

2019100043 15 Jan 2019 addition, the bottom bed structure 1 is expanded and folded easily and quickly, such that the user expands and folds the bottom bed structure 1 conveniently.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
