A bed having a stacked frame < RTI ID = 0.0 >

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed having a laminated horizontal frame, and more particularly, to a bed having a plurality of horizontal frames provided between support rods and vertically stacking them together to increase the overall supporting rigidity of the bed frame, To a bed having a laminated lateral frame for preventing the frame from being deformed.

Generally, a bed is a kind of furniture widely used when a person puts a mattress on a frame and sleeps or rests, and the frame of the bed is closely related to the life of the bed.

In the conventional bed, the frame connecting the four supports is formed in the form of plywood and is screwed to the bracket. However, such a frame joint structure is warped by the internal deformation of the plywood due to the temperature and humidity, or by the external force, and a clearance is formed between the plywood and the bracket, and a crackling sound is generated by such a gap, There is a problem that the plywood easily breaks even under a small load.

Further, in the case of a frame composed of a plywood, since the cross-sectional shape of the plywood is a "1" shape, there is a structural problem in that even if a load is applied to any one place, Therefore, when a torsional load is applied to the plywood, the plywood easily bends or breaks.

As a prior art related to a bed frame, in Patent Publication No. 10-2012-0078430 (coupling device of a bed frame), a front and rear plate insertion holes are formed on one side of a pipe-shaped leg outer diameter, A front and rear plate insertion holes are formed in the front and rear plate insertion holes formed in the legs of the legs, and the front and rear plate insertion holes are formed in the front and rear plate insertion holes, A panel portion formed to have a side plate inserted therein and fastened by a coupling bolt through a coupling hole, and a support portion coupled to inner edge portions of the front and rear plates and the side plate of the panel portion.

The prior art is a technique of inserting a panel part in the form of a plywood plate into an insertion hole formed in a leg and fixing the panel part to a leg by means of bolts. Since there is no structure capable of supporting the panel part at the bottom, There is a gap between the coupling hole and the panel portion during the use process to generate noise and deformation and breakage of the panel portion.

As a prior art relating to another bed frame, Registration No. 20-0448465 (joining structure of a bed frame) is provided with a post on a corner of a bed, and two assembled plates orthogonal to each other with the post interposed therebetween, The connecting structure of the frame includes a connecting plate formed in a direction in which one side surface and the other side surface are mutually orthogonal to each other. In the intersection portion between one side surface and the other side surface of the connecting plate, a bent portion A first bracket having one or more fastening holes formed on one side surface and the other side surface of the connecting plate, and a second bracket disposed between one side surface of the one assembled plate and the connecting plate, And a second bracket having a '?' -Shaped hook formed on the surface thereof and passing through the fastening hole and fitting into the downward direction. This is presented.

However, although the prior art has the advantage that the first bracket and the second bracket can be easily combined, a portion where the assembly plate is substantially engaged is completely fastened to the first screw hole of the second bracket with the fixing screw, When a load is applied to the assembled plate due to such a structure, there is a problem that only the assembled plate is detached while the first and second brackets are engaged, and the first and second brackets and the assembled plate are engaged only by screwing Therefore, there is a problem that when the screw is loosened or a gap is generated, noise is generated.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a frame structure for a bed frame, comprising a plurality of horizontal frames, And to prevent a deformation due to a torsional load applied to a horizontal frame.

Hereinafter, preferred embodiments of the present invention will be described in detail. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1, a separate mattress M is used together with a bed frame as shown in FIG. 1, so that the support frame 10 can be used without using a plywood- A plurality of horizontal frames 30 provided between the horizontal frame 30 and the horizontal frames 30 are stacked vertically so as to increase the overall rigidity of the bed frames and prevent the vertical frames 30 from being deformed due to the torsional load applied to the horizontal frames 30. [ The present invention relates to a bed having a horizontal frame.

As shown in FIGS. 2 to 3, the bed having the laminated lateral frame of the present invention comprises a support base 10 vertically provided at each corner of the bed, a support member 10 fixed to the side surface of the support base 10 by welding, A plurality of first engaging holes 21 and a plurality of second engaging holes 21 formed in the bracket 20 so as to be vertically stacked in the bracket 20, A horizontal frame 30 in which a second engagement hole 31 is formed at a corresponding position and a screw member 40 are coupled through the first engagement hole 21 and the second engagement hole 31, A plurality of horizontal frames 30 can be fixed to the frame 20, respectively.

The structure of the present invention is largely constituted by a support frame 10, a bracket 20 and a horizontal frame 30, and a connecting rod 11 on which the bed mattress M is supported is supported by the inner side And both ends are fixed by welding. At this time, the connecting block 11 is fixed to the horizontal frame 30 located at the lowermost one of the stacked horizontal frames 30, and the mattress M is mostly covered with the stacked horizontal frames 30 without finishing with a separate plywood It also has the effect of being able to play a protective role.

The support base 10 is formed of a metal tube of a predetermined thickness and installed vertically, and a cap is coupled to the upper and lower ends, respectively. The support 10 may be formed in various shapes such as a circular shape or a square shape, but the side portions to which the bracket 20 is welded are preferably flat.

The bracket 20 of the present invention is welded to a suitable position of the support frame 10 in accordance with the direction in which the horizontal frame 30 is installed and the first engagement hole 21 is formed through the bracket 20 at a predetermined interval in the height direction . As shown in the figure, the brackets 20 are installed on one support 10 on both sides so that the horizontal frames 30 are connected in a " C "shape on a plane basis.

" 형태가 되어 가로프레임(30)을 양측에서 지지할 수 있도록 외판부(20a) 및 내판부(20b)로 이루어지되, 상기 외판부(20a)의 높이는 복수의 가로프레임(30)이 모두 수용될 수 있도록 한 높이로 형성되고, 상기 내판부(20b)의 높이는 최상단에 적층되는 가로프레임(30)과 밀착되지 않도록 더 낮은 높이로 형성되어 있다. 즉, 최상단에 적층되는 가로프레임(30)을 제외한 나머지 가로프레임(30)은 수직방향으로 눌러 끼워지고 최상단에 적층되는 가로프레임(30)은 측방향으로 눌러 밀착한 다음 브라켓(20)의 외판부(20a)에만 결합함으로써 조립의 편의성을 높이는 구조를 갖는다.Further, the bracket 20 has a cross-

The outer frame 20a and the inner frame 20b are formed so that the horizontal frame 30 can be supported on both sides of the frame 30. The height of the outer frame 20a is set such that the plurality of horizontal frames 30 are all accommodated And the height of the inner plate portion 20b is set to a lower height so as not to be in close contact with the horizontal frame 30 stacked at the upper end of the horizontal frame 30. That is, The other horizontal frame 30 is pushed in the vertical direction and the horizontal frame 30 stacked on the uppermost portion is pressed in the lateral direction and then engaged with only the outer plate portion 20a of the bracket 20, .

An upper support plate 20a-1 bent in the horizontal direction is integrally formed on the upper surface of the outer plate portion 20a so that the uppermost horizontal frame 30 of the horizontal frame 30, So as to be able to be supported in contact with the upper end surface. In the conventional bed structure, when a screw is loosened so that the frame and the bracket can be engaged with each other, a creaking noise is generated as the frame swings up and down,

The present invention has such a structure that even when the screw member 40 is loosened, the horizontal frame 30 is supported upward by the upper support plate 20a-1 of the outer plate portion 20a, The problem that the horizontal frame 30 is detached from the outside of the bracket 20 does not occur, and no creaking noise also occurs.

As shown in FIG. 4, the transverse frames 30 of the present invention are provided in a plurality of units and are stacked inside the bracket 20. At this time, the plurality of horizontal frames 30 may have different heights, but they are all formed to have the same width so that they can be inserted in accordance with the width of the inside of the bracket 20. The horizontal frame 30 is formed with a second engaging hole 31 at a position corresponding to the first engaging hole 21 of the bracket 20. The second engaging hole 31 is set at the same height as the position of the first engaging hole 21 formed in the bracket 20 and is fixed by the screw member 40 when the transverse frame 30 is stacked.

As described above, according to the present invention, the horizontal frame 30 is fixed in the form of a laminated structure inside the bracket 20, and the mattress M of the bed can be sufficiently protected and supported without using a plywood- The overall rigidity of the bed frame can be increased. In the present invention, when a torsional load is applied to the transverse frame 30, since the plurality of transverse frames 30 are independently fixed to the inside of the bracket 20 at minute intervals, deformation such as warping does not occur There is a structural problem in that if the frame is formed by a single frame rather than a lamination method, the load is irregularly transmitted to the entire section even if a load is applied to only a part of the frame.

5, the first engaging hole 21 of the bracket 20 is formed in a shape in which the first protrusion 22 formed in the inward direction is narrowed, The second engaging hole 31 is formed in a shape corresponding to the first engaging hole 21 so that the second engaging hole 31 is narrowed to form the second protrusion 32. When the first frame 30 is inserted, So that the first projecting portion 22 of the engaging hole 21 can be fitted and fixed to the second engaging hole 31. By inserting the horizontal frame 30 into the bracket 20 through the above-described coupling structure and fixing the position of the coupling hole, the primary fixing is performed and the fixing member is firmly fixed together with the screw member 40. Also, even if a part of the screw member 40 is partially lost during use, the horizontal frame 30 is not detached.

Hereinafter, the joining process of the horizontal frame 30 will be described with reference to FIGS.

First, the bracket 20 is fixed to the support frame 10 by welding, and then the plurality of horizontal frames 30 are stacked one by one as shown in FIG. The second engaging hole 31 of the transverse frame 30 is forcibly inserted into the first projecting portion 22 of the first engaging hole 21 in the stacking process and the portion to be fitted is the bracket 20 and the transverse frame 30, The first protruding portion 22 is fitted into the second engaging hole 31 and is fixed while being restored together with a sound of "snapping ".

The horizontal frame 30 positioned at the lower part of the bracket 20 is inserted into the bracket 20 while being horizontally inserted into the bracket 20, It is preferable that the horizontal frame 30 which is to be positioned at the bottom so as not to be interfered is directly inserted into the first engaging hole 21 located at the lower portion in the diagonal direction .

7, the uppermost horizontal frame 30 is inserted not in the vertical direction but in the lateral direction of the bracket 20 so that the outer plate portion 20a of the bracket 20 and the upper support plate 20a-1 are inserted, So that the first engaging hole 21 of the outer plate portion 20a and the second engaging hole 31 of the transverse frame 30 are fitted to each other to perform primary fixing.

After the bracket 20 has been inserted into the bracket 20 and the bracket 20 has been completely fixed to the bracket 20, the bracket 20 is finally fixed to the bracket 20 through the screw member 40, A secondary fixation is made through the hole 31. The screw member 40 may be configured to be fastened to each other through a screw member 40 having a female screw shape on both sides as shown in the figure, And the second engagement hole 31, as shown in Fig.

9 is a perspective view illustrating a state where the second engaging hole 31 is formed on both side portions of the transverse frame 30 from the top to the bottom of the first engaging hole 21 and the second engaging hole 31, And the first engaging hole 21 of the bracket 20 is formed with a cutout 23 so as to be divided into two sides at the center of the first projecting portion 22, 30, the first protrusion 22 is pushed inward along the guide groove 33 and can be fitted while being restored at the position of the second engagement hole 31. [ By further forming the guide groove 33 and the cut-out portion 23, the coupling process can be easily performed. Since the horizontal frame 30 stacked at the uppermost end is not structured to be inserted in the vertical direction within the bracket 20, the guide groove 33 may not be formed.

In addition, the present invention can be applied to a double-layer bed as shown in FIG.

The height of the supports 10 at the corner portions may be higher and the bracket 20 and the horizontal frame 30 may be provided in the same position in the second layer. Since the horizontal frame 30 is rigidly fixed to the bracket 20 and has a structure resistant to the load, the stability of the bed frame can be ensured even when the horizontal frame 30 is formed as a two-layer structure.

While the present invention has been described with reference to the exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
