Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) This invention relates to a cushion device that can be used as a sofa having a pinerest or armrest.

(Prior Art) There are various types of cushion devices that can be used by converting them into sofas, mattresses, etc. One of these is a device in which a pair of members are connected by a hinge mechanism, and the hinge mechanism allows one member to be held at an arbitrary angle relative to the other member. According to this structure,
If the pair of members is made horizontal, it can be used as a pinerest, and if one member is made to stand up at a predetermined angle, the upright member becomes the backrest, and the horizontal member becomes the seat. This can be used as a sofa.

Such a structure can certainly be used for both a sofa and a pinerest. However, when used as a sofa, it has only a seat and a backrest but no armrests, which is not only inconvenient but also unsightly in appearance.

Therefore, the present applicant proposed a cushion device as shown in Japanese Patent Application No. 61-58596. In this prior art, an armrest body is formed from a first armrest member and a second armrest member whose one ends are pivotally connected to each other, and the other end of the first armrest member is pivotally connected to a first base member. , the other end of the second armrest member is pivotally connected to the second base member. Then, by standing the second base member at a predetermined angle, the first base member
Since the connecting portion between the armrest member and the second armrest member is bent, it can be used as an armrest.

However, with this structure, the armrest and the second base member serving as the backrest are separate members, resulting in an increase in the number of parts and complicated assembly work. Further, when used as a sofa, the second base member, which serves as a backrest, is made to stand up at the rear end of the first base member. In such a structure, unless the width of the second base member is increased to a certain extent, a sufficient height of the backrest cannot be obtained when used as a sofa. However, when the width dimension of the second base member is increased, the joint part between the first base member and the second base member, which has different cushioning properties from other parts when it is made into a pinerest, is located exactly at the center of the width direction of the pinerest. Because it will be located in
This may result in decreased sleeping comfort.

(Problems to be solved by the invention) As described above, in the conventional cushion device, the number of parts increases in order to provide an armrest, and it is not suitable for use with both a pinerest and a sofa. There was no way I could do that.

This idea was created based on the above circumstances, and its purpose was to provide an armrest without increasing the number of parts, and to be able to comfortably use it on both a pinerest and a sofa. The object of the present invention is to provide a cushion device that can perform the following functions.

[Structure of the idea]

(Means and effects for solving the problems) In order to solve the above problems, this invention includes a base member, and one end rotatably connected to the front end side of both sides of the base member. A pair of connecting members, a movable member having a substantially U-shaped planar shape and having both ends rotatably connected to the other ends of the connecting members, and a movable member provided between the movable member and the base member. The movable member is rotatably connected to the base member, and the base member is connected to the base member by a hinge mechanism so that the movable member can be held at a predetermined rotation angle. It is provided with a support rod that is supported substantially horizontally above the rear end side. The movable member can be used both as an armrest and a backrest, and can also be used as a backrest having a predetermined height without increasing the width of the movable member.

(Example) An example of this invention will be described below with reference to the drawings. The cushion device shown in FIG. 1 includes a base member 1 in the shape of a rectangular plate. This base member 1
A first cushion material 2 such as urethane foam is bonded to the upper surface of the first cushion material 2.
is covered with a first exterior material 3. First supports 4 (only one is shown) are provided on the upper surface of both front end sides of the base member 1, respectively. Each support 4 rotatably supports a support shaft 6 provided at the front end of a connecting member 5 (only one of which is shown) arranged on both sides of the base member 1. At the rear end of each connecting member 5, both ends of a movable member 7, which has a substantially U-shaped planar shape, are connected to the rear end of each connecting member 5 by hinges 8 so as to be freely flexible. This movable member 7 is formed in a size that surrounds the rear end and both sides of the base member 1. A second cushion material 9 is attached to the movable member 7 and the connecting member 5.
are joined, and this second cushion material 9 is covered with a second exterior material 11. In addition, the connecting member 5
The movable member 7 and the movable member 7 are covered with a second cushion material 9 and an exterior material 11 in a state of being slightly bent upward.

On the lower surface of the movable member 7, a support rod 12 made of pipe material bent into a U-shape approximately corresponding to the movable member 7 is rotatably supported at its midpoint by a second support 13. It is provided. Both ends of the support rod 12 are connected to a hinge mechanism 15 disposed at the central portion in the depth direction on both sides of the base member 1 via a mounting plate 14. This hinge mechanism 15 is designed to hold the support rod 12 at a predetermined rotation angle.

According to the cushion device configured in this way, when the movable member 7 is not rotated and raised as shown by the solid line in FIG. 1 or FIG. the second cushion material 9 and the base member 1
Since the first cushion material 2 attached thereto is substantially flush with the first cushion material 2, the plane formed by these can be used as a bed surface. In other words, the cushion device can be used as a pinerest.

When converting the cushion device from a mattress to a sofa, the movable member 7 is lifted upward. Then, the support rod 12 is attached to this movable member 7.
The hinge mechanism 15 is interlocked and connected to both ends of the hinge mechanism 15.
It rotates while operating. An intermediate portion of the support rod 12 is rotatably connected to the movable member 7 via a second support 13. Therefore, supporting rod 1
2 rotates about the end connected to the hinge mechanism 15 as a fulcrum, the movable member 7 connected to this support rod 12 not only rises but also moves forward. At this time, the connecting member 5 rotates about the support shaft 6 while being bent at the connecting portion with the movable member 7. When the movable member 7 is raised to a predetermined position, the support rod 12 is held at that position by the hinge mechanism 15 without falling down. Therefore, the movable member 7 is the base member 1
Its middle part located above can be used as a backrest, and both sides can be used as armrests.

That is, not only can the movable member 7 be used as both a backrest and an armrest, but the user's back can be supported at a sufficient height regardless of the width of the movable member 7. In other words, in order to provide the movable member 7 with a good function as a backrest, there is no need to increase its width. , 9 is used as a bed surface, there is no possibility that the joined portion of these parts will be located at the center of the bed surface in the width direction and impair the user's feel.

Note that this invention is not limited to the above-mentioned example,
For example, instead of using one support rod, two L-shaped support rods may be used.

[Effects of the invention] As described above, this invention connects a movable member having a U-shaped planar shape to a base member rotatably via a connecting member, and connects this movable member to the rear end side of the base member. It is now possible to hold it above. Therefore, when converted into a sofa, the middle part of the movable member can be used as a backrest, and the both sides can be used as armrests, reducing the number of parts compared to the conventional case where the backrest and armrests were made of separate members. can be done. Furthermore, since the movable member is displaced upward, the user's back can be supported at a predetermined height position regardless of its width. Therefore, since the width dimension of the movable member can be made sufficiently small and the width dimension of the base member can be made large, when used as a pine tress, the joint part between the base member and the movable member can be placed towards the end in the width direction. It is located at the top of the bed and does not impair the feel of the user, so it does not cause a decrease in sleeping comfort.
