The present invention relates to a rotary elastic restoring bed.

A bed is a piece of furniture made for people to lie down to sleep in. It has been passed down over many years, from ancient Egypt to modern times, and has various forms depending on the conditions such as ethnicity, climate, and lifestyle.

The bed where the upper mattress is rotatable for medical use or for the convenience and exercise of the user is usually located in the state where the upper part of the mattress is parallel to the floor. The user reaches a constant angle by rotating the upper part of the mattress by using a rotating device. When it was fixed, it was to be used.

Such a swivel bed is divided into a simple swivel bed and a complicated swivel bed using a cylinder.

In the case of the double simple swivel bed, the rotating shaft is mainly located on the lower plate, and the back plate rotates even if the user gives very little force.In this case, the user's back and waist are lying on the back while the user is standing up. Tension will arise.

That is, the user does not lean slowly on the back while comfortably leaning on the back, but suddenly rotates with only a little force, causing tension on the user's back and waist.

The rotary bed of the complicated structure using a piston, a cylinder, etc. to be distinguished from the simple rotary bed as described above, the back plate is to be rotated by the user load by the cylinder rod or the piston rod, but the structure has a complicated problem.

Rotating elastic restoring bed of the present invention is to solve the above problems and problems, while having a simple structure, the back has an elastic restoring force toward the initial position, raise the height of the point to become the axis of rotation and suddenly the back of the back by a small force The purpose is not to strain the user's back and waist by not rotating smoothly.

In addition, while providing a feeling of stiffness when rotating by the elastic device while providing a feeling of tension while providing a bed for back and back muscle movement when repeating lying or sitting motion.

In addition, there is also an object to provide a bed that can be rotated left and right together when the user moves the shoulder left and right while leaning on the back.

In particular, the back plate can be rotated from side to side as well as front and back, as well as the back and waist movements, there is also an object to provide a comfortable bed.

In addition, there is also an object to provide a bed that is always in the form of a chair before the user lies down to become a bed only when the user applies a load of the back.

In the present invention, the rotation type elastic restoring bed has a rotational coupling position of the lower plate and the back plate higher than the lower plate, and an elastic device is installed on the back plate so that the back plate does not suddenly rotate due to a small force.

As a result, the user may not only relax the user's back and waist, but may also have an exercise effect through repetition of lying and sitting motions.

In addition, the back is rotatable to the left and right to provide a more comfortable feeling to the user when leaned on the back, and can provide not only the back and waist but also the flank movement.

Rotating elastic restoring bed of the present invention, the back is erected like a chair at any time without a separate operation, the back is to be laid back only when the user applies a load.

To this end, the rotary elastic restoring bed of the present invention, the lower mattress to support the lower body of the user; A back plate support having one side connected to the lower mattress and the other side protruding from the upper upper mattress; An upper mattress rotatably connected to the protruding point of the back support in a forward and backward direction; And an elastic device installed between the back support and the lower mattress below the connection point of the back support and the upper mattress to provide an elastic restoring force against a force to be rotated in the horizontal direction by the upper mattress.

Rotating elastic restoring bed of the present invention may be installed to rotate the upper mattress from side to side with the back support.

In addition, the rotating elastic restoring bed of the present invention may further comprise a fixing device for fixing the plate of the upper mattress against the back support of the lower mattress so as not to rotate.

In addition, the rotary elastic restoring bed of the present invention may be installed so that the back support is rotatable on the lower mattress.

Prior to the description of the invention, the terms or words used in this specification and claims should not be construed as limiting in their usual or dictionary meanings, and the inventors have set forth the terminology in order to best describe their invention in the best way possible. Based on the principle that the concept can be properly defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.

The lower mattress 100, which is a component of the present invention, is configured to support the hips and legs of the user as shown in FIGS.

A preferred configuration of the lower mattress 100 is a lower cushion member 110 having a soft and fluffy material at the top, as shown in Figures 4 to 10, and the lower plate 120 for supporting the lower cushion member 100 thereunder Can be configured.

The lower cushion member 110 may be formed of various materials and structures, such as leather seats, wood, spring mats,

The lower plate 120 is preferably a metal material.

As shown in FIGS. 1 and 2, a bed pillar 910 and a bed frame 900 supporting the lower mattress 100 and the upper mattress 300 to be described later may be installed below the lower mattress 100.

In addition, as shown in Figure 3 may be provided with a support device with a wheel 920 on the lower mattress 100 to be suitable for using the rotary elastic restoration bed of the present invention as a chair combined.

The back support 200, which is a component of the present invention, has one side connected to the lower mattress 100, and the other side is formed to protrude upward from the lower mattress 100.

In this case, the reason why the back support 200 protrudes upward from the lower mattress 100 is to fit the connection point of the upper mattress 300 and the back support 200 to be described later as much as possible to become the rotation axis of the human body.

The connection between the back support 200 and the lower mattress 100 is fixed to one side of the back support 200 on the lower plate 120 of the lower mattress 100 by welding or the like, as shown in FIGS. 4 to 6. The back support 200 may be formed of a metal material having elasticity.

In addition, as shown in FIGS. 7 to 10, the lower plate 120 and the back plate support 200 of the lower mattress 100 are pin-coupled using the back plate support rotary pin 230, based on the lower plate 120. The back support 200 may be configured to rotate.

In the former case, the back support 200 may be laid back to some extent by elasticity. In the latter case, the back support 200 is rotated so that the rotation angle of the upper mattress 300 becomes larger.

In configuring the latter back support 200 to rotate, the back support fixing device 800 to adjust the rotation of the back support 200 can be further configured.

As an example of a configuration of the back support fixing device 800, after forming the back support fixing hole on one side of the lower plate 120, and preparing the back support fixing member to be inserted into the hole according to the user operation, the back support in the back support fixing hole Inserting the fixing member may prevent the back support 200 from rotating over the back support fixing member.

Alternatively, the back support 200 may be fixed by applying pressure to the back support 200 to be rotated.

That is, according to the operation of the user by operating the handle by configuring the back support contact member and the handle that is in close contact with the back support 200 according to the user's operation, the back support contact member is in close contact with the back support 200 to rotate the support 200 Can be prevented.

Since the configuration of the support plate fixing device 800 may be installed by referring to the rotation prevention device disclosed in the prior art, a specific illustration will be omitted.

The upper mattress 300, which is a component of the present invention, is connected to the protruding portion of the back support 200 so as to be rotatable in the front and rear directions with respect to the user.

Like the lower mattress 100, the upper mattress 300 also has an upper cushion member 310 having a fluffy material on one side, and an upper plate 320 supporting the upper cushion member 310, as shown in FIGS. 4 to 10. ) Can be configured.

Coupling position of the upper mattress 300 and the back support 200 is preferably pinned from the top of the back support 200 protruding into the lower mattress 100 as shown in FIGS.

In order to allow the upper mattress 300 to be rotatable back and forth with respect to the backrest support 200, a hinge 330 is installed on one side of the rear side of the upper plate 320 of the upper mattress 300, and on the upper end of the backrest support 200. By installing the hinge shaft 220 inserted into the hinge 330, the upper mattress 300 can be rotated.

As the upper mattress 300 is rotatably coupled to the portion protruding to the upper portion of the backrest support 200 as described above, when the user leans against the upper mattress 300, the distance between the rotating shaft and the upper mattress 300 is short. Will not give tension on the waist.

This is the case of the conventional bed is the main axis of rotation lower than the same or lower than the mattress (100) position when the user leans back, the distance between the axis of rotation and the upper mattress 300 is long distinct that it is distinct from the tension on the user's waist Since the axis of rotation is directly behind the lower end of the upper mattress 300, specifically, the hips above the hip, the distance between the axis of rotation and the upper mattress 300 is short so that the user's waist is not tense during rotation.

The upper mattress 300 may not only be coupled to the back support 200 so as to be rotatable back and forth, but may also be formed such that the upper mattress 300 may rotate left and right as the user moves the left and right shoulders.

Specifically, as shown in FIG. 4, after the upper plate 320 of the upper mattress 300 is formed with the rotation pin insertion hole 340, the rotation pin 500 is inserted into the rotation pin insertion hole 340. One side of the rotary pin 500 is fixed to the back support 200, and the other side is fixed to the upper plate 320 by a nut, the upper mattress 300 as the upper plate 320 rotates around the rotating pin 500 ) Can be rotated.

In this case, the bearing 510 having the rotation pin 500 as an axis may be installed on the front and rear surfaces of the upper plate 320 to further smooth the rotation.

As described above, the upper mattress 300 may be fixed to the back support 200 to be rotatable.

In other words, the upper mattress fixing device 700 is applied by applying various fixing methods such as the back support fixing device 800 described above to maintain the inclined state of the upper mattress 300 at a predetermined angle while the user is lying down. Can be configured.

Specifically, by applying a pressure to the upper plate 320 of the upper mattress 300 to install the lever to stop the rotation or by applying a pressure directly to the hinge shaft 220 to rotate the hinge 330 to the axis to force the rotation You can also stop it.

For example, after protruding one side of the hinge shaft 220 long, and installing a locking piece to which the protruding hinge shaft 220 is caught, a lever is installed to adjust the position of the locking piece so that the locking piece is hinged according to the operation of the lever. The upper mattress 300 may be fixed by preventing the hinge shaft 220 from rotating by being caught by the 220.

On the other hand, in installing the back support 200 to be rotatable can provide an elastic restoring force to the back support 200.

That is, when the backing support 200 is arbitrarily rotated, the connecting part of the backing support 200 and the lower plate 120 may be rotated about an axis. It is preferable to prevent such a point.

To this end, a spring support is installed between the backing support 200 and the lower plate 120 or the backing support elastic device 600 of the operation method such as the elastic device 400 to be described later as shown in FIG. 200 can have elastic restoring force in a direction opposite to the direction of rotation.

As such, the method of providing the elastic restoring force to the backrest support 200 may be implemented using various components similar to the elastic device 400 described later in addition to the simple spring.

On the other hand, the upper mattress 300 is installed on the back of the elastic device 400 to be described later to install the cover 350 to the outside of the elastic device 400 in consideration of aesthetics, the cover 350 is fixed to the upper plate 320 The cover fixing nut 360 may be installed.

The elastic device 400, which is a component of the present invention, is installed between the back support 200 and the upper mattress 300 under the connection point of the back support 200 and the upper mattress 300 so that the upper mattress 300 is horizontal. It is intended to provide an elastic restoring force against the force to rotate in the direction.

As a specific example, as shown in FIG. 4, a support shaft insertion hole 210 is formed under a portion connected to one side of the upper mattress 300 of the back support 200, and one side of the back support 200 is connected to the upper mattress 300. The spring support shaft 410 is installed to protrude out of the back plate support 200, the spring 420 is installed around the spring support shaft 410 protruding out of the support plate, and the spring at the end of the spring support shaft 410. The support plate 430 may be installed to block the 420, and the nut 440 may be installed to fix the position of the support plate 430 outside the support plate 430 to configure the elastic device 400.

In addition to the above shape, the elastic member may be implemented by simply installing a plate-shaped elastic member or spring between the back support 200 and the upper plate 320 of the upper mattress 300.

The support shaft insertion hole 210 is preferably formed so that the support shaft is inserted and left to spare.

The upper mattress 300 is rotated about the top of the back support, so that the angle between the top of the top mattress 300 and the top of the back support is wide enough to allow sufficient margin in accordance with the angle of rotation of the top mattress 300.

The elastic device 400 configured as described above allows the upper mattress 300 not to rotate arbitrarily so that the user rotates only when the user's pressure is continuously applied so that the user can exercise the muscles without giving tension to the user's back and waist. .

An operation example of the present invention configured as described above will be described with reference to FIGS. 4 to 10.

4 shows that one side of the back support 200 is fixed to the lower plate 120 of the lower mattress 100 by welding or the like, and the other side protrudes above one side of the lower mattress 100 to have an 'L' shape. .
