Description
Technical Field
[0001] This utility model relates to the field of beds, and in particular to a soft bed headboard and a bed using the same. Background Technology
[0002] The headboard (also known as the headboard) of a common upholstered bed mainly consists of an inner wooden frame, an attached elastic layer, and an outer covering fabric. The wooden frame is relatively flexible and allows for various connection combinations. Therefore, the elastic layer needs to be divided into multiple individual pieces to better cover and match the wooden frame. The headboard also incorporates a grooved structure that causes the covering fabric to tighten inwards, forming an inward-sloping groove, thus tensioning the covering fabric to ensure a tight fit and wrapping around the elastic layer. The groove can be formed independently on a single piece of covering fabric or at the seam of two pieces of covering fabric.
[0003] The existing tufting structure is completed manually by professional upholsterers. The upholsterers sew the elastic tufting fabric and the covering fabric to be tightened together, then pull the tufting fabric taut towards the inside of the mattress to flex the covering fabric. For example... Figure 1 The example shown uses a leather cover. The fabric connecting the cover is secured to the wooden frame inside the upholstered bed with a row of nails to keep the cover taut. Because the fabric itself is elastic, when manually pulling the fabric to tighten the cover, the tension along the length of the groove is not only dispersed but also uneven, resulting in inconsistencies in the tightening effect. As shown in the diagram, the tension T1"≠T2"≠T3" in each part of the fabric. Therefore, the tension at different locations on the cover is different. The nail positions for securing the fabric are also randomly selected by the upholsterer based on personal experience, resulting in uneven and inconsistent grooves. Because each upholsterer's technique and force are different, the pulling direction and force will vary. Even if the same upholsterer operates the same bed for all positions, the groove effect at different locations on the headboard will not be consistent. Utility Model Content
[0004] To address the technical problems of uneven, inconsistent, and non-uniform grooves formed by using fixed fabric to tighten the covering material in existing soft bed backrests, this utility model provides a soft bed backrest and a bed using it. The covering material of the soft bed backrest can be evenly tensioned to form a straight groove effect with uniform depth.
[0005] The technical solution adopted by this utility model to solve the technical problem is as follows: A soft bed backrest includes a support frame, multiple elastic layers that fit and wrap around the support frame, and a covering fabric covering the elastic layers. The support frame has a central support surface, two side surfaces at both ends, and at least one groove structure. The groove structure allows the covering fabric to collapse inward to form a groove. The groove structure is characterized by including a rigid body fixedly connected to the covering fabric, with several tension ropes attached to the rigid body. The ropes tension the rigid body, causing the covering fabric to collapse inward. After tensioning the rigid body, the ropes can pass through the support surface and one side of the elastic layer and / or the side surface and one side of the elastic layer before being fixed to the support frame. This utility model uses a rigid body fixedly connected to the covering fabric, and tension ropes to pull the rigid body to tighten the covering fabric, causing the covering fabric to collapse inward to form a groove. The rigid body applies uniform force to each connection point with the covering fabric, resulting in straight grooves of consistent depth.
[0006] As a further improvement and supplement to the above technical solution, the present invention adopts the following technical measures: the pull rope is fixed to the support frame corresponding to the support surface, or passes through the support surface and is fixed to the support frame on its rear side. When the pull groove is formed on the side of the end of the bed headboard, the pull rope passes through the side of the end of the support frame and the elastic layer on the same side and is fixed to the support frame corresponding to the support surface; when the pull groove is formed on the front of the bed headboard, the pull rope passes through the support surface and the elastic layer on the same side and is fixed to the support frame on the rear side of the support surface.
[0007] The pull rope is secured to the support frame with nails to maintain tension. Fixing the pull rope with nails is not only simple and easy to operate, but also fast, efficient, and reliable. A pneumatic nail gun, commonly used on construction sites, can be used to fix the pull rope.
[0008] The grooved structure is located on the side of the support frame and / or on the supporting surface. When the grooved structure is on the side of the support frame, the groove extends vertically; when the grooved structure is on the supporting surface of the support frame, the groove extends vertically or horizontally. The grooved structure can be flexibly configured according to the specific material covering the headboard surface of the soft bed. When the grooved structure is located on the side of the support frame, i.e., at both ends of the headboard, the groove extends vertically; when the grooved structure is on the supporting surface of the support frame, i.e., at the front of the headboard, the groove can extend vertically and / or horizontally.
[0009] When the grooved structure is on the side of the support frame, the support frame has a through-hole for the pull rope to pass through on the side and the corresponding elastic layer; when the grooved structure is on the supporting surface of the support frame, the support frame has a through-hole for the pull rope to pass through on the supporting surface and the corresponding elastic layer. Regardless of whether the grooved structure is on the side or the supporting surface of the support frame, the corresponding elastic layer has a through-hole for the pull rope to pass through.
[0010] The rigid body is sewn and fixed to the inner surface of the covering fabric; or the covering fabric is made of multiple outer fabrics sewn together, with two adjacent outer fabrics sewn together to hold the rigid body. The rigid body can be directly sewn and fixed to the inner surface of the covering fabric, and the covering fabric can be folded and sewn together with the rigid body. When the rigid body is pulled, the covering fabric also moves, causing the covering fabric to collapse inward to form a groove; the rigid body can also be sewn at the joint of two outer fabrics and held by the two outer fabrics sewn together. When the rigid body is pulled, the covering fabric moves, and the joint of the two outer fabrics collapses inward to form a groove.
[0011] The rigid body is covered by a protective sleeve, which is then fixedly connected to the covering fabric. The pull cord extends out from the protective sleeve. The function of the protective sleeve is to protect the rigid body while positioning the pull cord connected to it, preventing one end of the pull cord from shifting on the rigid body. Especially when there are multiple pull cords, the protective sleeve can effectively limit the position of each pull cord on the rigid body, ensuring that there is a preset interval between the pull cords.
[0012] The rigid body is a steel bar with a circular cross-section and a diameter of 3-5 mm. Using a circular cross-section steel bar as the rigid body ensures that the entire perimeter of the rigid body has the same arc shape, eliminating the need to consider direction and angle when assembling and fixing it with the covering fabric. With the steel bar diameter within this range, it has sufficient rigidity when pulled taut by the rope, maintaining the stability of the pull groove.
[0013] The ropes are fixed at equal intervals along the length of the rigid body at one end. Because each rope is connected to the rigid body at equal intervals, when all the ropes tighten the rigid body, the rigid body is uniformly stressed along its length.
[0014] The second objective of this invention is to provide a bed comprising a headboard, a footboard, and a middle side panel. The headboard is equipped with a headboard, characterized in that the headboard is a soft headboard as described in the first part. Beds using the aforementioned soft headboard have straight grooves with minimal variation in depth, resulting in a uniform grooved effect.
[0015] The beneficial technical effects of this utility model are as follows: by using a rigid body to replace the fabric puller to move the covering fabric, and at the same time using a pull rope to pull the rigid body to tighten the covering fabric, the covering fabric collapses inward to form a groove. The rigid body applies force evenly to tighten the covering fabric, resulting in a good consistency of groove effect, with straight grooves and consistent depth. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 2-10As shown, Embodiment 1 is a soft bed backrest, including a support frame 3, multiple elastic layers 4 that fit and wrap around the support frame, and a covering fabric 5 that wraps around the elastic layers. The support frame 3 has a central support surface, two side surfaces at both ends, and at least one groove structure. The groove structure allows the covering fabric 5 to collapse inward to form a groove 8. The groove structure includes a rigid body 1 fixedly connected to the covering fabric. Several tension ropes 2 are connected to the rigid body 1. One end of each rope 2 is connected to a tension rope fixing position 9 on the rigid body, which is equidistant along the length of the rigid body. All the ropes tighten the rigid body 1, causing the covering fabric 5 to collapse inward. After tightening the rigid body 1, the ropes 2 pass through the support surface and the elastic layer 4 on one side or the side surface and the elastic layer 4 on one side, and are then fixed to the support frame 3. In this embodiment, the rigid body 1 is a steel bar with a circular cross-section and a diameter of 3-5 mm. The support surface here refers to the internal structure of the headboard that provides support for the human body. Besides using a wooden board directly as the support surface, it can also be composed of multiple horizontally arranged wooden strips, multiple elastic bands along the vertical strips, and sponge glued to the surface of the elastic bands. Both types of support surfaces can have the aforementioned grooved structure. The sides of the support frame can be multiple wooden strips or a single piece of board. Other parts of the support frame are equipped with appropriate wooden strip or board structures depending on the reinforcement and support requirements. Reinforcement refers to ensuring the structural strength required for the support frame, and support refers to reserving adhesive fixing positions where the elastic layer needs to be attached to the headboard, such as providing adhesive surfaces for wooden strips, board strips, or elastic bands. For example, the support frame is a wooden frame consisting of a front panel, a back panel, and two side panels. The pull rope passes through the front panel where the support surface is located and the elastic layer on the same side, and is then fixed to the back panel. In this embodiment, the back panel consists of multiple separated panels to provide operating space for the pull rope.
[0029] The pull cord tightens the rigid body, causing the covering fabric to taut. The covering fabric at the location of the rigid body collapses inward, forming a groove. The rigid body applies even force to all connections between itself and the covering fabric, resulting in straight grooves of consistent depth and good uniformity. Figure 2 As shown, the spacing between adjacent pull ropes is equal, and the working section length of each pull rope is consistent, so that the tension of each pull rope on the rigid body is equal. The tension of each pull rope on the rigid body in the figure is T1=T2=T3=T4=T5.
[0030] Furthermore, the pull rope 2 is fixed to the support frame 3 in two ways. Taking the pull groove formed on the end side of the headboard as an example, the first state is... Figure 8 The pull rope shown is taut along a straight line, and its rear end is directly fixed to the support frame; the second state is... Figure 10 The pull rope shown is taut, and its rear end is bent before being secured to the support frame. Regardless of which of the aforementioned methods the pull rope is used to secure it to the support frame, it will... Figure 9As shown, the fabric is held taut by being fixed to the support frame 3 by the nail 10, so as to pull the rigid body 1 to tighten the covering fabric.
[0031] Furthermore, the groove structure can be located on the side of the headboard end corresponding to the support frame 3, or on the support surface of the headboard front area corresponding to the support surface of the support frame 3, or simultaneously on both the aforementioned side and support surface. This embodiment uses the groove structure on the side of the support frame 3 as an example. The pull rope passes through the side of the headboard end and the elastic layer on the same side, and is then fixed to the support frame corresponding to the support surface. The support frame 3 has a through-hole 6 for the pull rope 2 on its side and the corresponding elastic layer 4. The groove is formed on the side of the headboard end and extends vertically. Additionally, when the groove structure is on the support surface of the support frame 3, the pull rope passes through the support surface and the elastic layer on the same side, and is then fixed to the support frame on the rear side of the support surface. The support frame has a through-hole for the pull rope on the support surface and the corresponding elastic layer. The groove is formed on the front of the headboard and extends vertically and / or horizontally.
[0032] Furthermore, such as Figure 4 As shown, the rigid body 1 can also be sewn and fixed to the inner surface of the covering fabric 5, or the covering fabric 5 can be made of multiple outer fabrics 51 sewn together, with two adjacent outer fabrics sewn together to clamp the rigid body 1. Here, the rigid body can be directly sewn and fixed to the inner surface of the covering fabric. The covering fabric can be a single outer fabric folded and sewn together with the rigid body. When the rigid body is pulled, the covering fabric moves in conjunction with it, causing the covering fabric to collapse inward to form a groove. When the rigid body is sewn at the joint of two outer fabrics and is clamped by the two outer fabrics, when the rigid body is pulled, the covering fabric moves in conjunction with it, and the joint of the two outer fabrics collapses inward to form a groove. In this embodiment, it is preferred that the rigid body is clamped by two sewn outer fabrics.
[0033] To protect the rigid body and to limit the fixing positions of each rope on the rigid body, such as... Figure 5 As shown, the rigid body 1 can first be wrapped with a protective sleeve 7, and then fixedly connected to the covering fabric 5, with the pull rope 2 extending out from the protective sleeve 7.
[0034] Example 2 is a bed comprising a headboard, a footboard, and a middle side panel. The headboard is equipped with a headboard, which is the soft headboard described in Example 1. The grooves on the bed are straight, with minimal variation in depth, resulting in a uniform groove effect.
