Such a sofa is generally in the shape of a bench, and includes a seat on which the user sits and a backrest that leans against the body, and armrests may be provided at both ends of the seat. Products that include a stool that can lie down are popular.

However, since the stool is large in size and carries considerable weight, it is not easy to change the position arbitrarily once the position is determined, and since the armrest is generally provided in a fixed form on both sides of the seat, it is also difficult to change the position.

In addition, the conventional stool is not easy to move due to its large size and occupies a significant part of the space, but its utilization is low, so when purchasing a sofa or using it after purchasing a sofa, it is a reality that concerns about continuous use are accompanied.

Accordingly, there are cases in which the stool is released in the form of a wheel attached to the lower part of the stool, but there is a problem that the position of the stool is easily changed. There is an inconvenience that must be done, and it is not possible to solve the problem of always taking up considerable space regardless of whether the stool is used or not.

On the other hand, since the armrests are fixed on both sides of the seat, a user seated in the center of the sofa cannot use the armrests, and users sitting on both sides of the sofa have to use the armrests without wanting.

In addition, when the auxiliary sofa is disposed on the side of the sofa, there is a problem that considerable inconvenience is caused when the arrangement of the sofa and the auxiliary sofa is changed, such as the armrest must be removed for continuity between the main sofa and the auxiliary sofa.

In order to solve this problem, armrests can be selectively attached and detached, and armrests that are compatible with both sides have been disclosed. However, such a conventional sofa has a shape in which the armrests are inserted into grooves formed at both ends of the backrest, so that the armrests are Limits that can be located only at both ends and when the armrests are removed, the grooves for fixing the armrests are empty, which is inconvenient, and a separate member to fill the fixing grooves is additionally required or the member is not lost. It is difficult to secure the convenience of use due to the occurrence of ancillary problems such as having to be carefully stored for the purpose.

In another embodiment, when the armrest rail 120 is formed in a'T' shape, it can be moved along the armrest rail 120 by having a hollow hexahedral body with an open lower part and a rotating roller on the inner wall of the body. have.

In another embodiment, when the armrest rail 120 has a'+' shape, the armrest includes a hexahedral body with an open lower part and a rotating roller of a two-layer structure spaced apart from each other on the inner side of the body. It can be configured to be movable along the rail 120.

In this way, the armrest coupling portion 510 may also be configured in various shapes according to the shape of the armrest rail 120.

At this time, if there is a device that can move smoothly and easily along the armrest rail 120 in addition to the rotating roller, any device may be used.

If the above-described armrest rail 120 is formed with a locking protrusion, if the rotation roller does not apply more than the reference value, the position of the armrest 500 is not changed by being caught by the locking protrusion, preventing the position of the armrest 500 from being arbitrarily changed. can do.

For this purpose, it is preferable that the diameter of the rotating roller is relatively smaller than the inner height of the armrest rail 120, and engaging protrusions are formed at equal intervals along the length direction on the lower side of the armrest rail 120 corresponding to the rotating roller. .

When the locking protrusion is formed in this way, if a force above the reference value occurs, the rotation roller crosses the locking protrusion and changes its position. If a force below the reference value occurs, the rotation roller does not cross the locking protrusion, so the position is arbitrarily changed. Can be prevented.

The armrest connection part 520 has one end coupled to one side of the armrest coupling part 510, preferably the upper one side of the armrest coupling part 510 body, and the other end through the seat 200 and the backrest 300 to the outside. It may be configured to be exposed to a predetermined length.

The armrest connection part 520 is preferably made of a rigid material such as a metal material, and may be bent into various shapes in consideration of the shapes of the seat 200 and the backrest 300, or may be formed in the shape of a curved flat plate, pipe, or rod. .

In FIG. 5, the armrest connection part 520 has a length corresponding to the length of the armrest 500 so that the user can stably transmit the force to the armrest coupling part 510 even if the user grasps any part of the armrest 500 and moves. Although shown, the exposed length may be selectively determined in consideration of the length and thickness of the armrest 500.

The armrest cushion part 530 is provided at one end of the armrest connection part 520 and may be configured in consideration of the shape of the backrest 300 and the seat 200, the height of the armrest 500, and user convenience.

Since the armrest cushion unit 530 has a configuration similar to the armrest 500 commonly used in the art, a detailed description will be omitted.

Meanwhile, the armrest 500 may be configured to include a toothed rail 130 and an armrest toothed 540 as an additional means for preventing a set position from being arbitrarily changed.

The toothed rail 130 is a shape of a rail having teeth formed on the surface, and is configured to be positioned parallel to the armrest rail 120 in the space between the armrest rail 120 and the seat 200 provided on one side of the sofa frame 100. I can.

The armrest sprocket 540 is a circular sprocket, and may be provided in a form capable of being engaged with the sprocket rail 130 and movable by being positioned at the lower end of the armrest connector 520 with a rotating shaft connected to the armrest connector 520.

The armrest teeth 540 may provide a predetermined limited force capable of preventing the position set by the user from being arbitrarily changed because the armrest 500 is moved too easily along the armrest rail 120.

That is, when the armrest 500 moves along the armrest rail 120, a minimum criterion that can be moved by applying a predetermined force may be set as the engagement between the armrest teeth 540 and the tooth rail 130.

At this time, the above-described locking protrusions are formed at a sufficient distance within the armrest rail 120 at a predetermined interval or more, and in the space between adjacent locking protrusions, the armrest 500 is used as the armrest teeth 540 and the tooth rail 130 Regardless of the intention, the position can be prevented from being arbitrarily changed.

The use of the armrest 500 in the stool mobile sofa 10 according to the present invention having the above-described configuration will be described in detail as follows.

The stool mobile sofa 10 of the present invention, as shown in Figure 4, even if the user does not sit at both ends of the seat 200, if the user wants to use the armrest 500 after seating at a desired position, the armrest 500 ) Can be moved to use.

As an example, both armrests 500 may be moved so that both armrests 500 may be placed on both sides of the armrest 500 like a personal sofa.

In another usage mode, when seated in the center of the sofa, only one armrest 500 can be moved to place an object, or it can be used over the user's arm.

In another usage mode, when the user is lying on the seat 200, one armrest 500 is used as a pillow according to the user's body shape, and the other armrest 500 is an armrest ( 500) can be used by changing the placement position.

As described above, when the position of the armrest 500 is changed according to various usage modes and the needs of the user, the armrest 500 can be smoothly moved along the armrest rail 120 through the armrest coupling part 510 Therefore, the user can easily change the position of the armrest (500).

In addition, since the position of the armrest 500 can be freely changed even when an auxiliary sofa or the like is disposed on the left or right side of the sofa, unlike the left type or right type sofa, it is possible to freely arrange furniture in the user's living room or office.

Accordingly, the user can freely arrange the sofa without changing the sofa, so that various atmospheres can be created.

Since the armrest cushion part 530 of the armrest 500 according to the present invention is provided so as to be in close contact with the seat 200, the armrest cushion part 530 and the seat 200 face each other even when a predetermined force is generated when the user uses it. The armrest 500 does not move arbitrarily when friction occurs on the one side and no more than a certain force is generated.

Accordingly, the user can use the armrest 500 more conveniently and stably.

Meanwhile, the toothed rail 130 is configured in parallel to the armrest rail 120, and the armrest tooth 540 is connected to the armrest connection 520 to form a structure that meshes with the toothed rail 130, so that a predetermined force of the minimum standard is applied. By setting the limit so that the armrest 500 can move, the armrest 500 slides along the armrest rail 120, but it is possible to prevent the position of the armrest 500 from being arbitrarily changed regardless of the user's intention.

In addition, depending on the usage mode, a locking protrusion having a predetermined height along the length direction is formed on the inner side of the armrest rail 120 to more reliably prevent the armrest 500 from moving arbitrarily.

That is, when the rotation roller provided in the armrest coupling part 510 to drive the armrest 500 receives a force greater than the reference value, it passes through the locking protrusion of the armrest rail 120 and the position of the armrest 500 can be changed. have.

However, when the user does not change the position of the armrest 500, for example, when a force below the reference value is transmitted to the armrest coupling portion 510, such as colliding with the armrest 500 during use, the armrest coupling portion Since sufficient force is not transmitted to the 510, the rotating roller is caught by the locking protrusion and cannot be moved, so that the change is not made at the placement position set by the user.

As described above, the armrest 500 is arbitrarily arranged by at least one of the frictional force generated from the armrest cushion portion 530 and the seat 200 of the armrest 500, the armrest teeth 540, and the locking protrusion Because it prevents from being changed, the arrangement position of the armrest 500 may be fixed without being changed by a user's mistake.

Through this, the user can more conveniently and stably fix and use the armrest 500 at a desired position.

On the other hand, as an additional embodiment of the stool mobile sofa 10 according to the present invention, the armrest rail 120 is observed at the bottom of the rear of the sofa frame 100 and communicates with the inside of the sofa frame 100 at a portion where the armrest rail 120 can be observed. Sized openings can be configured.

Therefore, when the armrest rail 120 is jammed while the stool mobile sofa 10 is being used, or when checking and repairing the armrest rail 120 or the armrest coupling part 510, do not separate the seat 200 and the backrest 300. Even if not, it is possible to check or repair the defective part through the opening formed on the rear of the sofa frame 100.

In addition, an opening portion may be provided in the opening portion, and when the opening portion is not used, the opening portion may be closed using the opening portion, thereby preventing foreign substances from flowing into the sofa frame 100.

The example of using the stool 400 and the use of the armrest 500 of the stool mobile sofa 10 of the present invention described above may be applied, respectively, and may be applied at the same time.

For example, as an embodiment in which the stool 400 and the armrest 500 are used at the same time, the user can sit in the center of the stool mobile sofa 10 and move the armrests 500 at both ends closely to the user's body and arrange it. , The stool 400 located at the front end of the seat 200 is moved and placed in front of the user's seating position, but the stool extension unit 460 is extended to both ends of the stool 400 to stool food, books, notebooks, etc. It is placed on the extension part 460, and the foot is stretched on the body of the stool 400, and the convenience of working or taking a break while leaning on the armrest 500 can be promoted.

In addition to the above example, the user may change and use the stool 400 and the armrest 500 by moving and disposing each of the stool 400 and the armrest 500, thereby maximizing the convenience of use of the stool mobile sofa 10 of the present invention.
