Description

Sofa with removable armrests

The present invention relates to a sofa equipped with a movable armrest, and more particularly, a movable armrest for maximizing the convenience of use of the sofa by sliding the armrest according to the user's usage mode or the coupling direction of the auxiliary sofa, and placing it at a desired position by the user. It relates to a sofa with armrests.

Sofas are widely used in homes or offices as a daily necessity to provide a space in which users can rest comfortably. Such a sofa generally includes a seat on which the user can be seated and a back on which the user leans on his back. In addition, depending on the usage mode, it may include an armrest fixedly installed on at least one side of both end portions of the seat of the sofa.

Sofas equipped with such armrests are limited in use because they have a uniform shape. That is, since the user can use it only when he sits on the side of the seat with armrests, the user who wants to use the armrests cannot sit in the center of the sofa.

In addition, when an auxiliary sofa or the like is disposed on the side of the wide sofa, armrests may not be provided at the corresponding portion according to the arrangement position of the auxiliary sofa. Accordingly, even if the user tries to change the arrangement of the sofa and the auxiliary sofa, there is a problem that a lot of inconvenience is caused.

In order to solve this problem, an armrest compatible with both sides has been disclosed so that the armrest may be removed in consideration of the area and atmosphere of the installation site, the size of the sofa, or the like, or may be selectively attached or detached to the left or right side of the seat.

Such a conventional sofa has a shape in which armrests are fitted into grooves formed at both ends of the backrest. Such a conventional sofa has the advantage of selectively using armrests at both ends, but still has a problem that the position of the armrests is limited to both ends of the sofa.

In addition, when the armrest is not provided, it is inconvenient to use because the groove formed in the backrest or seat is empty, or a separate member is required to fill this space, and it is difficult to store such a separate member. If not used, there is a problem that there is a risk of loss.

Armrest 500 that is easily coupled to the guide rail 400 and the guide rail 400 without separating the seat 200 and the back 300 of the sofa 10 on one side of the rear of the base frame 100 according to the present invention. As shown in FIG. 5, the opening 110 may be formed so as to check and repair the coupling state of ). The size of the opening 110 may be formed in various sizes in consideration of the size of the sofa 10 and the like. In addition, an opening/closing unit capable of opening and closing the opening 110 may be further provided in order to prevent foreign substances such as external dust from entering through the opening 110. Any device that can open and close the opening 110 through various methods such as folding or sliding may be used.

The seat 200 is a device provided on one side of the upper portion of the base frame 100 to provide a space for a user to sit. In this case, the seat 200 is preferably provided so as to be spaced apart by a predetermined distance from one side to which the backrest 300 of the base frame 100 is coupled in order to provide a space in which the guide rail 400 can be disposed. The seat 200 may include a cushion member to improve comfort when a user is seated.

The backrest 300 is provided on one side of the base frame 100 on which the seat 200 is provided and the base frame 100 disposed at a predetermined angle to lean on the user's back. It is to provide a space to lean on. In this case, it is preferable that the backrest 300 is spaced apart from the upper surface of the base frame 100 by a predetermined interval to provide a space in which the guide rail 400 can be disposed. The backrest 300 may include a cushion member to improve comfort when the user leans on the back.

The above-described seat 200 and back 300 are commonly used in the art, and a detailed description thereof will be omitted.

The guide rail 400 extends the length direction along the width direction of the base frame 100 on one side of the base frame 100, preferably on one side of the base frame 100 to which the seat 200 and the backrest 300 are coupled. It is a device that is provided so as to provide a path through which the armrest 500 can slide. As for the guide rail 400, any device may be used as long as it is a device capable of providing a path through which the position of the armrest 500 can be changed. However, it is preferable that the armrest 500 has a length corresponding to the width of the sofa 10 so that the armrest 500 can be changed to a position desired by the user along the width direction of the sofa 10. These guide rails 400 may be configured to have various cross-sections in consideration of a method of coupling the armrests 500 and the like. As an example, as shown in FIGS. 2 to 4, it may be formed of a hollow pipe-shaped rail with one side of the upper surface open along the length direction. As another usage mode, it may be made of a rail having a cross section of a'T' shape or a'+' shape. In addition, depending on the usage mode, a plurality of locking protrusions may be formed on one side of the inner side along the length direction so that the position of the armrest 500 may be fixed to the position changed by the user.

The armrest 500 has one end coupled to the guide rail 400 to change its position, and the other end is exposed to the outside so that it can be seated on the top of the seat 200 so that the user can mount the arm when the seat 200 is seated. Or, depending on the usage mode, it is a device that allows the user to mount the head or feet while lying on the seat 200. The armrest 500 is largely composed of a coupling portion 510, a connection portion 520, and a cushion portion 530.

The coupling part 510 is a device that is coupled to the guide rail 400 to smoothly move the armrest 500 along the guide rail 400. The coupling part 510 may have various configurations and shapes according to the configuration and coupling method of the guide rail 400. For example, as described above, when the guide rail 400 is formed in a hollow pipe shape with an open upper portion shown in FIGS. 2 to 4, a hexahedral shape having an outer circumferential surface corresponding to the inner circumferential surface of the guide rail 400 It may include a body and at least one rotating roller provided on each side wall of the body. Accordingly, the rotating roller rotates, and smooth and smooth movement along the guide rail 400 is possible. In another embodiment, when the guide rail 400 is formed in a'T' shape, it can be moved along the guide rail 400 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 guide rail 400 has a'+' shape, the guide rail 400 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 surface of the body. It can be configured to be movable along the rail 400. As such, it may be configured in various shapes according to the shape of the coupling part 510. In addition, any device may be used as long as there is a device that can move smoothly and easily along the guide roller in addition to the rotating roller.

If a locking protrusion is formed inside the guide rail 400 described above, if the rotation roller does not apply a force above the reference value, the position of the armrest 500 is not changed by being caught by the locking protrusion, thereby 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 formed relatively smaller than the inner height of the guide rail 400, and engaging protrusions are formed at equal intervals along the length direction on the lower side of the guide rail 400 corresponding to the rotating roller. . When the locking protrusion is formed in this way, if a force above the standard value occurs, the rotation roller crosses the locking protrusion and changes its position. If a force below the reference value occurs, the rotation roller cannot cross the locking protrusion, so the position is arbitrarily changed. Prevent it.

The connecting portion 520 has one end coupled to one side of the coupling portion 510, preferably to one side of the upper portion of the coupling portion 510 body, and the other end exposed to the outside through a predetermined length between the seat 200 and the backrest 300 It is configured to be. At this time, the 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 back 300, or may be formed in the shape of a curved flat plate, pipe, or rod. have. 2 and 3, the 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 coupling part 510 no matter which part of the armrest 500 is moved. Although shown, the exposed length may be selectively determined in consideration of the length and thickness of the armrest 500.

The cushion part 530 is provided at one end of the 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 the user's convenience. Since the cushion part 530 has a configuration similar to the armrest 500 commonly used in the art, a detailed description will be omitted.

Use of a sofa with movable armrests

The usage mode of the sofa 10 having a movable armrest according to the present invention having the above-described configuration will be described in more detail with reference to the drawings as follows.

Figure 6 is a perspective view of a mobile armrest according to the present invention. As shown in FIG. 6, the sofa 10 with movable armrests according to the present invention intends to use the armrest 500 after seating at a desired position by the user even if the user does not sit at both ends of the seat 200. If you move the armrest 500 can be used.

As an example, both armrests 500 may be moved so that both armrests 500 can be spread over both armrests 500 like a personal sofa 10. In another usage mode, when seated in the center of the sofa 10, 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 guide rail 400 through the coupling part 510 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 the auxiliary sofa 10 is disposed on the left or right side of the sofa 10, the user's living room or office is different from the left type sofa 10 or the right type sofa 10. It is possible to freely arrange furniture on the back. For this reason, the user can freely arrange the sofa 10 without changing it, so that various atmospheres can be created.

Since the 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 cushion part 530 and the seat 200 face each other even if a predetermined force is generated during use by the user. In the case where friction occurs and no more than a certain force is generated, the armrest 500 does not move arbitrarily. Accordingly, the user can use the armrest 500 more conveniently and stably. In addition, depending on the usage mode, a locking protrusion having a predetermined height along the length direction is formed on an inner side of the guide rail 400 to more reliably prevent the armrest 500 from moving arbitrarily. That is, when the rotation roller provided in the coupling part 510 to drive the armrest 500 receives a force greater than the reference value, the position of the armrest 500 may be changed while passing through the locking protrusion of the guide rail 400. . 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 coupling portion 510, such as colliding with the armrest during use, the coupling portion 510 is sufficient. Since the force is not transmitted, 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 user's mistake because at least one of the frictional force and the locking protrusion generated from the cushion portion 530 and the seat 200 of the armrest 500 prevents the armrest 500 from arbitrarily changing the arrangement position. By this, the arrangement position of the armrest 500 is fixed. Through this, the user can more conveniently and stably fix and use the armrest 500 at a desired position.

When a rail is jammed during use of the sofa 10 having a movable armrest according to the present invention, or when checking and repairing the coupling portion 510 of the rail or armrest 500, the seat 200 and the backrest 300 Even without separating, as shown in FIG. 5, the faulty part can be checked or repaired through the opening 110 formed on the rear of the base frame 100. In addition, when the opening portion 110 is provided with an opening and closing portion when not in use, the opening portion 110 may be closed to prevent foreign substances from flowing into the base frame 100.

As described above, those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential features thereof. Therefore, the above-described embodiments are illustrative in all respects and should be understood as non-limiting. The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modified forms derived from the meaning and scope of the claims and equivalent concepts should be interpreted as being included in the scope of the present invention.
