Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and those skilled in the art can make modifications to the present embodiment which do not contribute to the utility model as required after reading the present specification, but are protected by the patent laws within the scope of the appended claims.

The embodiment relates to an office chair with a changeable afternoon nap, as shown in fig. 1, 2 and 3, comprising a chair seat 1, a chair back 2, a supporting plate 3, a tension plate assembly and a locking assembly 4.

The seat 1 is a main area of the chair for a user to sit, and is generally square or circular, and the legs 5 for supporting the seat 1 are disposed below the seat 1, in this embodiment, as shown in fig. 6, four legs 5 are disposed below the seat 1 and are disposed at four corners of the seat 1, so that the seat 1 is balanced and stable on the legs 5. Meanwhile, an I-shaped stabilizing frame 51 is arranged between the supporting legs 5 to fix the relative positions of the supporting legs 5, so that the seat 1 is more stable. Of course, in other embodiments, the stabilizer 51 between the legs 5 may take other shapes, such as a chevron shape, an X-shape, etc.

As shown in fig. 1, the backrest 2 is disposed at the rear side of the seat 1, and is used for supporting the waist and back of the user, thereby improving the comfort of the user. The bottom of the chair back 2 is hinged with the rear side of the chair seat 1, so that the chair back 2 can rotate at the bottom, and the chair back 2 can incline to meet different sitting postures of users, and even be placed on the same plane with the chair seat 1, so that the whole chair can be used as a bed for the users to lie down.

As shown in fig. 1, one end of the support plate 3 is hinged to the seatback 2, and the other end is freely rotatable. The support plate 3 is connected to the tension plate assembly through a locking assembly 4 to support the seat back 2 in a chair configuration as a whole. The other end of the supporting plate 3 can directly contact with the ground to support the back 2 for stability when the back 2 is inclined or even laid flat as a afternoon nap. Wherein the length of the supporting plate 3 is greater than or equal to the height of the chair seat 1, so that the other end of the supporting plate 3 can prop against the ground when the chair back 2 is flat, and the supporting effect is realized.

In this embodiment, as shown in fig. 4, a first connecting member 21 is provided at the rear middle of the seatback 2 for the connection plate to hinge. The second limiting plate 211 is disposed on the first connecting member 21, and the maximum angle of the support rotation is set by the second limiting plate 211: when the chair back 2 is put flat as a bed, the other end of the supporting plate 3 is positioned right below or behind the hinged position of the supporting plate, and the supporting plate just abuts against the ground to support the chair back 2. It is ensured that the end of the support plate 3 does not move backwards, resulting in its loss of support. Of course, in other embodiments, other structures may be used to limit the rotation angle of the support plate 3.

The tension plate assembly includes: tension plate 6 and elastic member 7. Wherein, tension plate 6 is connected to elastic component 7 one end, and the rear side of seat support 1 is connected to the other end, and tension plate 6 hangs below the rear side of seat support 1 through the effect of elastic component 7. When the backup pad 3 passes through locking subassembly 4 and connects pulling force board 6, because pulling force board 6 connects the movable structure that elastic component 7 formed for the back of the chair 2 that backup pad 3 supported can have the floating space of taking the resilience force in its rotatable direction, thereby when making the user back on back of the chair 2, can not feel back of the chair 2 too hard, promotes the comfort level of back of the chair.

In this embodiment, as shown in fig. 6, the tension plate assembly further includes: the first limiting plate 8 is arranged below the rear side of the seat 1 and is used for limiting the tension plate 6 to move only in the vertical direction, and the tension plate can not rotate in a sideways direction, so that the effect of the elastic piece 7 is maintained.

As shown in fig. 5, the tension plate 6 includes: a first plate surface 61 and a second plate surface 62. The first plate surface 61 is vertically arranged and is used for connecting the elastic piece 7; the second plate surface 62 is fixedly connected with the first plate surface 61 and horizontally arranged.

As a preferable embodiment, as shown in fig. 1, the elastic member 7 is a plurality of springs symmetrically disposed at both left and right sides of the first plate surface 61.

In the present embodiment, the support plate 3 is coupled to the upper side of the second plate surface 62 by the locking assembly 4. In other embodiments, the support plate 3 may also be attached to the underside of the second plate surface 62.

In the present embodiment, as shown in fig. 2 and 5, the locking assembly 4 includes: a locking member 41 provided on the support plate 3 and a locking hole 42 provided on the second plate surface 62. In other embodiments, the locking assembly 4 may have other structures to lock and unlock the support plate 3 and the tension plate 6

In this embodiment, as shown in fig. 1, a movable surface 9 is further disposed above the seat 1, and the front side of the movable surface 9 is hinged to the front side of the seat 1, so that the movable surface 9 can be turned around its front side to the front side of the seat 1 to the same plane as the seat 1, so as to increase the length of the whole bed, support legs, and improve the comfort of use.

As a preferred solution, as shown in fig. 3, two sides of the movable surface 9 are provided with armrests 91 protruding upwards for supporting the arms of the user, and at the same time, the movable surface 9 can be grasped as a handle when being turned, so that the user can turn the movable surface 9 more conveniently.

As a preferred solution, as shown in fig. 3, the rear side of the movable surface is provided with a cross bar 92 protruding upward to limit the forward rotation of the seat back 2, so as to ensure the posture of the seat back 2. Meanwhile, when the movable surface 9 is turned over, the movable surface 9 can be used as a handle for grabbing, so that a user can turn over the movable surface 9 more conveniently.

The working principle of the utility model, which is changed into a afternoon nap bed, is approximately as follows: unlocking the locking assembly 4 enables the chair back 2 to be placed on the same plane with the chair seat 1, and the supporting plate 3 supports the placed chair back 2 against the ground through one end, so that the chair back 2 is more stable. The movable surface 9 above the seat 1 is turned over to the front side of the seat 1 to be at the same level as the seat 1 for supporting the legs of the user.

The above description is only for the purpose of illustrating the technical solution of the present utility model and not for the purpose of limiting the same, and other modifications and equivalents thereof by those skilled in the art should be included in the scope of the claims of the present utility model without departing from the spirit and scope of the technical solution of the present utility model.
