Definitions
- This invention relates to reclining apparatus for supporting a human body according to the first part of claim 1.
- Such a reclining apparatus realized as a chair is known from GB-A-1,403,648.
- an angular rod is fixed at a seat member which is slidable in a groove of a fixing element which is protatably mounted at a support member.
- these two parts can not get jammed because of the rotatably mounting of the fixing element. Therefore, the different seat positions are not fixed shurely enough especially if the rod takes a more vertical position.
- the angular rod and the fixing element are relatively complicated mecanical parts which damage the appearance of the chair. High production costs are further disadvantages of this construction.
- the object of the invention is to provide a simply constructed and uncostly manufactured reclining apparatus which steplessly can be locked in a desirable reclining position.
- the lock member of the reclining apparatus comprises at least one rod movingly mounted at one of said seat member, said back member and said support member and slidingly guided across in at least one aperture of another one of them, whereby said rod being unlocked and slidable in the aperture in response to a force applied to an upper portion of said back member.
- the lock member When a force is applied only to the seat member, the lock member is locked to maintain the angle between the seat member and the back rest member. On the other hand, when a force is applied to both the seat member and the back rest member, the lock member is unlocked and moves to change the angle between the seat member and the back rest member.
- FIGs. 1A through 1C and Figs. 2A through 2C illustrate a wooden reclining chair 1 of a first embodiment.
- a seat member 3 supporting the lumbar region of a seated person is pivotably connected to a T-shaped support member 2 by a shaft 4.
- a back rest member 5 supporting the back region and the seat member 3 are adjustably connected to each other by a shaft 6 slidably fitted in a long aperture 7 provided on the middle portion of the longitude of the back rest member 5.
- the bottom of the back rest member 5 and the support member 2 are adjustably connected to each other by a shaft 8 slidably fitted in a long aperture 9.
- a rod 11 formed as an integral part of an arm rest 10 is secured on one end by the shaft 8 and is inserted across the seat member 3.
- Figs. 3A and 3B and Figs. 4A and 4B illustrate a lock, device 13, wherein the rod 11 is fitted through a rod through hole 12 provided in the seat member 3.
- the action of the first embodiment is now described.
- the support member 2, the seat member 3 and the back rest member 5 are adjustably interconnected, and the rod 11 of the lock device 13 is connected to the support member 2 and the seat member 3.
- the rod 11 may be connected to any two of the support member 2, the seat member 3 and the back rest member 5 or to all of the three.
- Fig. 4A shows the lock device in its lock position.
- the positions of the support member 2, the seat member 3 and the back rest member 5 are maintained.
- the weight is applied onto the seat member 3 and a certain force is applied to between the seat member 3 and the rod 11 inserted across the seat member 3.
- the rod 11 is then firmly engaged in the rod through aperture 12 and the angle between the rod 11 and the seat member 3 is maintained.
- Fig. 4B shows the lock device in its unlock position.
- the rod 11 is slidably moved in the through hole 12 of the seat member 3, and the positions of the support member 2, the seat member 3 and the back rest member 5 can be re-adjusted.
- the person is seated on the reclining chair 1 in the reclining position as shown in Figs. 2A through 2C.
- the weight is again applied onto the seat member 3 and a certain force is applied to between the seat member 3 and the rod 11 inserted across the seat member 3.
- the rod 11 is then firmly engaged in the rod through aperture 12 and the angle between the rod 11 and the seat member 3 is maintained as shown in Fig. 4A.
- the lock device 13 is not limited to the above construction but may have any other suitable constructions.
- the rod 11 may be fitted in a groove provided on the seat member 3.
- Figs. 5 and 6 are right side views of a reclining chair 21 of a second embodiment.
- Vertically extending support members 22a and 22c are interconnected by a transversely extending support member 22b.
- the upper end of the support member 22a is adjustably connected to a seat member 23 by a shaft 24 slidably fitted in a long aperture 29 provided on the seat member 23.
- a rod 31 provided to support an arm rest 20 is pivotably connected to the seat member 23 and a back rest member 25 by a shaft 26 and is slidably fitted in the support member 22b.
- Fig. 7 shows a lock device 33, wherein the support member 22b is fitted in a groove provided on the rod 31.
- the back rest member 25 is bent upward at the middle portion thereof and a long aperture is provided above the bent.
- the support member 22c is adjustably connected to the back rest member 25 by a shaft 28 slidably fitted in the long aperture 27.
- the lock device 33 is locked when the reclining chair 21 is in the sitting position as shown in Fig. 5 and the lock is released in the manner similar to the first embodiment.
- the lock device 33 When the lock device 33 is unlocked, it moves leftward and the rod 31 thus moves leftward.
- the seat member 23 accordingly slides leftward and the back rest member 25 rotates clockwise to slide left-downward.
- Figs. 8A through 8D and Fig. 9 illustrate a reclinable bed 41 of a third embodiment.
- Each lower end of links 39 and 40 is rotatably connected to a support member 42 by each upper shaft 44, and each upper end of the links 39 and 40 is articulatingly connected to a seat member 43 by each lower shaft 44.
- the seat member 43 and the support member 42 are thus interconnected by the links 39 and 40.
- a back rest member 45 is articulatingly connected to the link 39 by the shaft 44 and the rear part of the back rest member 45 is supported by a roller 46 provided on one end of the support member 42.
- One end of a rod 51 is supported by the support member 42 via a roller 47 of the rod 51 and the other end thereof is inserted across the seat member 43.
- a lock device 53 is clearly seen in Figs. 8A though 8D, wherein the rod 51 is fitted in a through hole 52 for the rod 51 provided in the seat member 43.
- Figs. 10A through 10C, Figs. 11A through 11C and Fig. 12 illustrate a reclining chair 61 of a fourth embodiment according to the invention.
- the main structure of the reclining chair 61 is similar to that of the chair 1 of the first embodiment; only the structure and the function different from those of the chair 1 are thus explained here.
- a second back rest member 75 is provided in parallel with a first back rest member 53 both to support the back region of a seated person.
- the lower portion of the second back rest member 75 is adjustably connected to a T-shaped support member 62 by a shaft 76 slidably fitted in a long aperture 69 provided on the support member 62.
- the middle portion of the second back rest member 75 is adjustably connected to the rear portion of a seat member 63 by a shaft 66 slidably fitted in a long aperture 67 provided on the first back rest member 55.
- any complicated controls for reclining such as manual controls are not required to change the sitting position on the reclining chair 61.
- the reclining chair is in the normalposition when a person is seated. When the seated person stretches himself for reclining, the reclining chair is automatically changed to be in the reclining position. Additionally, the reclining chair 61 is easily constructed and manufactured at a reasonable cost.
- any complicated controls for reclining such as manual controls are not required to change the sitting position on the reclining chair 61.
