## Background
This application is being filed within 12 months of the filing date of its parent application and accordingly claims Paris Convention priority from China patent application 201220578409.8 filed Jun. 11, 2012 entitled Electric Bed Bed board With Embedded Fixed Structure by same inventor Shan, Huafeng, the disclosure of which is incorporated herein by reference.
FIELD OF THE INVENTION
The present invention is in the field of electric bed bedboard with fixed connection structure.
DISCUSSION OF RELATED ART
An average person spends about one-third of their life in sleep; and thus, more and more attention has been put to achieve quality sleep by choosing the right bed that can bring people comfortable and healthy sleep. In order to meet the needs of the people, various types of electric beds came into widespread usage.
The traditional electric bed bedboard angle adjustment that allows the bed board to rise in the bedplate mattress easily slips from the foot of the bed due to the lack of friction in the bed board. To solve this technical problem, the angle of the electric bed may be adjusted so that it is installed at the foot of the bed frame above the mattress. In the process of rising and lowering, the bed frame may act as a barrier so that slipping is prevented. There are some shortcomings to this approach, such as the foot of the bed parts can not merely stay still which affects the overall appearance of the electric bed.
Also, mattresses are blocked by the frame when the bedboard is lifted several times. Mattress and mattress displacement may cause the bedplate to rise. There is no guarantee that the mattress and the bedplate is a good fit in the S-shaped angle. These shortcomings reduce the comfort of the electric bed, and hinder the beneficial effects of an electric bed.
Traditional electric beds have a hinged multi-piece bedplate. A variety of different traditional electric beds have been patented such as inventor David Hensley's articulating bed frame U.S. Pat. No. 6,006,379 issued Dec. 28, 1999, the disclosure of which is incorporated herein by reference. The typical bed having four planks hinged to each other may have poor connection between the mattress and the bed boards. Bedboards are also called bedplates.
SUMMARY OF THE INVENTION
This invention discloses an electric bed bedboard with embedded fixed structure. The fixed structure includes a plurality of guide pieces, multiple sliders, multiple disc sleeve and two pieces of wood, a plurality of guide pieces. Multiple guide pieces are set on top of the bedboard and also have T-shaped slots on their surface. Many disc sleeves are stacked on top of the wood pieces at intervals and there are internal threads inside the disc sleeves. Two pieces of wood are fixed into the bed support at intervals and the disc sleeves position matches with the guide pieces. Multiple sliders are “stem” shaped sliders and have external threads on their top. Multiple sliders are situated on top of the guide pieces inside the T-shaped slots. Multiple sliders' tops are situated inside the multiple disc sleeves which have connection by the threads. The fixed structure allows the mattress reliable formation to align with the bed plate, to avoid the slipping of the mattress bed plate during the lifting process, to improve the comfort of the electric bed, and to ensure the overall appearance and effect of the electric bed.
The present invention discloses an electric bed bedboard with embedded fixed structure; wherein the mattress can reliably be fixed to the bedplate to avoid slipping during the bedplate lifting process. This method allows for continued comfort, and ensures the overall appearance and effect of the electric bed.

Further, the electric bed bedboard with embedded fixed structure comprises a plurality of washers wherein the top surface of a plurality of washers is located in two boards. It is positioned to complement a plurality of disc sleeves. The washer disc sleeves are bolted through the wood fastening in a clamping installation to ensure the reliability of positioning, and to avoid drilling damage.
The electric bed bedboard with embedded fixed structure includes: a plurality of guide pieces, multiple sliders, multiple disc sleeves and two pieces of wood, a plurality of guide pieces at the top surface of the open T-slots, multiple disc sleeves in two pieces of wood and in the sleeve inner rings, two pieces of wood embedded in the mattress. Wherein the multiple disc sleeves, plurality of guide pieces, and multiple “stem” shaped sliders are located at the bottom of a plurality of guide pieces which are located at the top surface of the T-shaped slots. The fixed structure allows the mattress reliable formation that complements the bed plate, to avoid the slipping of the mattress during the lifting process, to improve the comfort of the electric bed, and to ensure the overall appearance and effect of the electric bed.
An electric bed bedboard with embedded fixed structure is characterized in that the fixed structure comprises a plurality of guide pieces, a plurality of sliders, a plurality of disc sleeves, two planks of wood, a plurality of guide pieces, located at the headboard and the top surface of the open T-slots, respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4 above, the present invention of an electric bed bedboard with an embedded fixed structure includes a plurality of guide pieces 3, a plurality of sliders 4, a plurality of disc sleeves 5 and two pieces of wood. The plurality of guide pieces 3 on bedboard 1 has a T-shaped slot 31 and the top surface of the plurality of disc sleeves 5 is located in the two pieces of wood on the sleeve inner ring. The two pieces of wood 2 and the disc sleeve 5 position and the plurality of guide pieces 3 position complements the plurality of “stem” shaped sliders 4 and the top of the outer thread 41 is provided, wherein a plurality of the sliders 4 are located at the bottom of a plurality of guide pieces at the top surface of the T-shaped slot 31. A plurality of the sliders 4 are located within the disc sleeve 5 at the threaded connection where the threaded connection threads connect together the disc sleeve to the slider on the outer thread 41.
Additionally, there can be at least four sets of connectors comprising the plurality of guide pieces 3, the plurality of sliders 4, and the plurality of disc sleeve 5.
Additionally the guide pieces 3 can have a T-shaped slot 31 with an end being a trumpet shaped opening 32. The trumpet shaped opening provides an easier insertion of the mattress onto the guide pieces. The guide pieces 3 are elongated and have an elongated channel with a top portion of the elongated channel cut with a slot such that a T-shaped slot 31 is formed. The guide pieces 3 are preferably secured to the bedboard 1 by connection screws.
Additionally, this structure also includes multiple washers 7. The multiple washers 7 are located on the top surface of the two boards 6 and above disc sleeves 5. The washers are fastened in their respective locations by matching washer 7 to disc sleeve 5 via bolts through the board 6.
The fixed structure is simple. Reliable connection is achieved through the planks of the disc sleeve being fixed to the underside of the mattress. A bed plate setting corresponds to the position of the guide pieces, and the disc sleeves are connected with the guide pieces through the “stem” shaped slider. The bottom of the slider inserts into the guide piece T-shaped slot. The top of the slider extends into the disc sleeve through threading, securing the mattress to the bedplate.
During the mattress securing process the slider is initially screwed in the bottom surface of the disc sleeve. Then the mattress is aligned with the matching side of the bed board and then slid toward one side.
When more than one slider at the bottom connects with the matching multiple T-shaped grooves of the guide pieces, the mattress can be fixed to the bed plate. Separation can be handled by sliding the mattress in the reverse direction. Multiple sliders slide out of the T-shaped slot of the of guide pieces, and then the mattress and bed board can be separated.
At the same time, because the slider and the disk sleeve have a threaded connection, the disc sleeve, through the planks, are fixed to the underside of the mattress. The mattress in the installed position has a traction effect, and therefore avoids an S-shape mattress when the bed board is rising.
In addition, the planks can be embedded into the mattress with wood adhesives. Then the sponge can cover the structure. Also, the inner ring of the disc sleeve threads are situated at hollow part of the sponge so that the slider can be easily screwed into it.
The structure of the fixed guide pieces is made according to the size of the bed and the bed carrying capacity between the mattress and the bed board.
Preferably, the quantity of connectors among the guide piece slider and disc sleeves are at least four or more, to give the mattresses a reliably smooth connection to the bedplate. Once affixed the connection structure is hidden so that the mattress appearance is clean. The fixed structure has hidden connections, the mattress has clean a and beautiful appearance and is convenient to install and affix to provide the mattress and bed board a close fit without relative sliding.
The “stem” shaped sliders 4 preferably terminate at a bulbous downwardly facing mushroom shaped head that has a rounded bottom portion for ease of insertion into the channel of the guide pieces.
