Abstract
Description
Technical Field
[0001] This utility model relates to a bed structure, specifically a bed structure that makes it easy to change the bed sheet. Background Technology
[0002] Hotels and similar establishments typically have guest beds in every room. Existing guest beds have a complex structure, requiring staff to make and change the sheets daily. Each time the sheets are made, the sides need to be tucked into the gap between the bed frame and the mattress, requiring considerable effort and potentially injuring the staff's hands if not handled carefully. Before changing the sheets, staff must also forcefully pull the old sheets out of the gaps. Due to the unreasonable design of the existing bed structure, changing and making sheets is time-consuming, laborious, and somewhat dangerous. Furthermore, the existing bed structure has a single piece of material between the bed frame and mattress, making it difficult to clean the dust that accumulates under the mattress on the inside of the bed frame after prolonged use, hindering cleaning. Therefore, the inventor has improved the bed structure. Utility Model Content
[0003] The purpose of this utility model is to provide a bed structure that makes it easy to change sheets. This bed structure is simple in structure and reasonable in design, allowing service personnel to easily lay and change sheets, eliminating the trouble of manually stuffing sheets into gaps and the hassle of pulling sheets out forcefully during changing, thus avoiding injury to service personnel's hands. It also facilitates cleaning of the inner space of the bed frame, achieving the advantage of easy dust removal, and solving the problems mentioned in the above-mentioned technical background.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a bed structure that facilitates easy sheet replacement, comprising a bed frame and a bed board mounted on the bed frame. The width of the bed board is greater than the width of the bed frame, and both ends of the bed board are equipped with sheet positioning mechanisms. Each sheet positioning mechanism includes a mounting plate, which is a hollow cavity structure with an opening at one end. The cavity opening of the mounting plate is located on its lower end face. A positioning strip is fixed within the cavity. Above the positioning strip, a lifting assembly and a pushing assembly located on one side of the lifting assembly are provided. The lifting assembly includes a first fixed seat, and the pushing assembly includes a second fixed seat fixed to one side of the first fixed seat. Both the first and second fixed seats are hollow cavities with an opening at one end. A passive slider and a horizontal plate located below the passive slider are provided within the cavity of the first fixed seat. The passive slider is slidably positioned. Within the cavity of the first fixed seat, a horizontal plate is fixed within the cavity of the first fixed seat. Below the horizontal plate, a first spring, a limiting strip, and a connecting rod are provided. The two ends of the first spring are connected to the horizontal plate and the limiting strip, respectively. The connecting rod is connected to the upper end face of the limiting strip and passes through the horizontal plate from bottom to top, connecting to the passive slider, thereby driving the passive slider to rise and fall. Within the cavity of the second fixed seat, a second spring and an active slider are provided. The two ends of the second spring are connected to the second fixed seat and the active slider, respectively. The active slider passes through the second fixed seat from the inside to the outside and enters the cavity of the first fixed seat. The ends of the active slider and the passive slider that are close to each other are both inclined surfaces with the same inclination angle, allowing the passive slider and the active slider to push each other. An operating rod is fixed at the end of the active slider that is away from the passive slider. The operating rod passes through the second fixed seat from the inside to the outside and extends to the outer side of the second fixed seat.
[0005] Preferably, the two mounting plates are arranged in parallel and are both rectangular in shape, and both mounting plates are fixed to the lower end surface of the bed board.
[0006] Preferably, both the first fixing seat and the second fixing seat are fixed in the cavity of the mounting plate, and the end of the first fixing seat near the second fixing seat is provided with a slot, and the end of the active slider away from the second spring passes through the slot and enters the cavity of the first fixing seat.
[0007] Preferably, the limiting strip is positioned directly above the positioning strip, and the limiting strip has an arc-shaped inner wall. The positioning strip has an arc surface that perfectly matches the arc-shaped inner wall, thus increasing the contact area with the bed sheet and achieving a better limiting effect on the bed sheet.
[0008] Preferably, a gap is provided between the limiting strip and the positioning strip. When both the first spring and the second spring are in their natural state, the value of the gap is between 2cm and 4cm. This value is the distance between the limiting strip and the positioning strip in the vertical direction.
[0009] Preferably, the bed also includes a decorative panel and a padded panel, wherein two decorative panels are provided and are symmetrically installed at both ends of the bed frame, and the padded panel is installed on the upper surface of the bed board.
[0010] Preferably, two parallel slide rails are fixed on the bed frame, symmetrically distributed at both ends of the bed frame. Multiple pulleys are slidably installed in each slide rail, and brackets are installed on each pulley. The brackets are fixed to the lower end of the bed board. The bed board can move horizontally above the bed frame, which drives the multiple pulleys to move horizontally in the two slide rails respectively, opening up the space inside the bed frame. This facilitates the storage of items in the space inside the bed frame and also makes it easier to clean the space inside the bed frame, achieving the effect of easy cleaning.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model provides a bed structure that facilitates easy sheet changing. The bed structure includes a bed frame and a bed board mounted on the bed frame. Sheet positioning mechanisms are provided at both ends of the bed board. The overall structure is simple and rationally designed. The sheet positioning mechanism includes a mounting plate, which is a hollow cavity structure with an opening at one end. The cavity opening is located on the lower end face of the mounting plate. A positioning strip is fixed inside the cavity. A lifting assembly and a pushing assembly are provided above the positioning strip. The lifting assembly includes a first fixed seat, and the pushing assembly includes a second fixed seat fixed to one side of the first fixed seat. Both the first and second fixed seats are hollow cavities with an opening at one end. A passive slider and a horizontal plate located below the passive slider are provided inside the cavity of the first fixed seat. The passive slider is slidably disposed within the cavity of the first fixed seat, and the horizontal plate is fixed within the cavity of the first fixed seat. A first spring is provided below the horizontal plate. The system consists of a spring, a limiting strip, and a connecting rod. The two ends of the first spring are connected to the horizontal plate and the limiting strip, respectively. The connecting rod is connected to the upper end of the limiting strip and passes through the horizontal plate from bottom to top, connecting to the passive slider, thereby driving the passive slider to rise and fall. The cavity of the second fixed seat contains a second spring and an active slider. The two ends of the second spring are connected to the second fixed seat and the active slider, respectively. The active slider passes through the second fixed seat from the inside to the outside and enters the cavity of the first fixed seat. Since the width of the bed board is greater than the width of the bed frame, the two sides of the bed board extend outwards. Therefore, when laying the sheet, the service person only needs to pull the operating lever with one hand to move the limiting strip to the highest position, and use the other hand to insert the two sides of the sheet into the two mounting plate cavities and into the two gaps. Then, the person releases the operating lever, and under the action of the two sets of springs, the edge of the sheet presses against the positioning strip, ensuring that the sheet will not easily shift during use.
[0013] 2. In this utility model, the active slider is fixed with an operating rod at the end away from the passive slider. The operating rod passes through the second fixed seat from the inside to the outside and extends to the outside of the second fixed seat. When changing the bed sheet, the service personnel only need to pull the operating rod to raise the limiting strip, thereby increasing the width of the gap and releasing the restriction on the bed sheet. This allows the bed sheet to be easily removed, eliminating the trouble of manually stuffing the bed sheet into the gap between the bed frame and the mattress. It also eliminates the trouble of pulling out the bed sheet with effort during the change, and avoids squeezing the service personnel's hands. Therefore, it is easy to promote and use.
[0014] 3. The bed frame of this utility model has two parallel slide rails fixed on it. The two slide rails are symmetrically distributed at both ends of the bed frame, and multiple pulleys are slidably installed in each of the two slide rails. Each pulley is equipped with a bracket, and the brackets are fixed to the lower end of the bed board. Therefore, the bed board can be moved horizontally above the bed frame, which drives the multiple pulleys to move horizontally in the two slide rails respectively, opening up the space inside the bed frame. This facilitates cleaning of the space inside the bed frame and achieves the effect of easy dust removal, making it highly practical. Attached Figure Description

[0025] Please see Figure 1 The present invention provides an embodiment of a bed structure that is easy to change sheets. The bed structure includes a bed frame 1 and a bed board 2 set on the bed frame 1. The width of the bed board 2 is greater than the width of the bed frame 1, and both ends of the bed board 2 are provided with a sheet positioning mechanism 3. The bed structure also includes a decorative panel 4 and a soft pad 5. There are two decorative panels 4, and the two decorative panels 4 are symmetrically installed at both ends of the bed frame 1. The soft pad 5 is installed on the upper surface of the bed board 2.
[0026] Please see Figures 2 to 3The diagram shows the state when changing the bed sheet. The bed sheet positioning mechanism 3 includes two mounting plates 31 arranged in parallel, both of which are rectangular plates. Both mounting plates 31 are fixed to the lower end face of the bed board 2. Each mounting plate 31 is a hollow cavity structure with an opening at one end. The cavity opening of the mounting plate 31 is located on its lower end face. A positioning strip 32 is fixed inside the cavity. Above the positioning strip 32, a lifting assembly 33 and a pushing assembly 34 located on one side of the lifting assembly 33 are arranged. The lifting assembly 33 includes a first fixed seat 331, and the pushing assembly 34 includes a second fixed seat 341 fixed to one side of the first fixed seat 331. Both the first fixed seat 331 and the second fixed seat 341 are fixed inside the cavity of the mounting plate 31. The fixed bases 341 are all hollow cavity structures with an opening at one end. A passive slider 332 and a horizontal plate 333 located below the passive slider 332 are installed inside the cavity of the first fixed base 331. The passive slider 332 is slidably disposed within the cavity of the first fixed base 331, and the horizontal plate 333 is fixed within the cavity of the first fixed base 331. A first spring 334, a limiting strip 335, and a connecting rod 336 are arranged below the horizontal plate 333. The two ends of the first spring 334 are connected to the horizontal plate 333 and the limiting strip 335, respectively. The limiting strip 335 is located directly above the positioning strip 32 and has an arc-shaped inner wall 3351. The positioning strip 32 has an arc surface that perfectly matches the arc-shaped inner wall 3351, thus increasing the contact area with the bed sheet. To achieve better limiting effect on the bed sheet, the connecting rod 336 is connected to the upper end face of the limiting strip 335, and the connecting rod 336 passes through the horizontal plate 333 from bottom to top and is connected to the passive slider 332, thereby driving the passive slider 332 to rise and fall. A gap 35 is provided between the limiting strip 335 and the positioning strip 32. When the first spring 334 and the second spring 342 are both in their natural state, the value of the gap 35 is between 2cm and 4cm. This value is the distance between the limiting strip 335 and the positioning strip 32 in the vertical direction. The cavity of the second fixed seat 341 is provided with a second spring 342 and an active slider 343. The two ends of the second spring 342 are respectively connected to the second fixed seat 341 and the active slider 343. The active slider 343 passes through the second fixed seat 341 from the inside to the outside. 41. The active slider 343 and the passive slider 332 are both inclined at their closest points, with the same inclination angle, allowing them to push against each other. An operating lever 344 is fixed to the end of the active slider 343 furthest from the passive slider 332. The operating lever 344 passes through the second fixed seat 341 from the inside out and extends to the outside of the second fixed seat 341. Furthermore, a slot 337 is provided at the end of the first fixed seat 331 closest to the second fixed seat 341. The end of the active slider 343 furthest from the second spring 342 passes through the slot 337 and enters the cavity of the first fixed seat 331. When laying the sheet, the service worker only needs one hand to pull the operating lever 344.The second spring 342 is compressed, causing the active slider 343 to retract into the cavity of the second fixed seat 341. At this time, under the action of the first spring 334, the limiting strip 335 and the connecting rod 336 rise, causing the passive slider 332 to rise, increasing the value of the gap 35. The service person then uses their other hand to insert the two sides of the sheet into the gap 35 respectively. Afterwards, the service person releases the operating rod 344, and under the action of the two sets of springs, the edge of the sheet is pressed between the limiting strip 335 and the positioning strip 32, ensuring that the sheet will not easily shift during use. The operation for changing the sheet is the same and will not be described further here.
[0027] Please see Figures 4 to 5 This is a diagram showing the state of the bed sheet being laid out, with a gap of 35 compared to... Figure 3 The state shown is significantly shortened, and the bed sheet can be sandwiched between the limiting strip 335 and the positioning strip 32.
[0028] Please see Figure 6 Two parallel slide rails 6 are fixed on the bed frame 1. The two slide rails 6 are symmetrically distributed at both ends of the bed frame 1, and multiple pulleys 7 are slidably installed in each of the two slide rails 6. Each of the multiple pulleys 7 is equipped with a bracket 8, and the multiple brackets 8 are fixed to the lower end surface of the bed board 2. Therefore, the bed board 2 can move horizontally above the bed frame 1, and drive the multiple pulleys 7 to move horizontally in the two slide rails 6 respectively, opening up the space inside the bed frame 1, making it easier to clean the space inside the bed frame 1, and achieving the effect of easy cleaning.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
