Abstract: A chair seat device includes a lower seat and an upper seat softer than the lower seat and permitting restitution when compressed. The upper seat includes a top board having front and rear lower edges coupled with front and rear lower edges of the lower seat. Two openings are formed in left and right sides of the coupled upper and lower seats. At least one elastic element is coupled to the lower seat and includes an upper supporting portion shorter than the upper seat. The upper supporting portion includes front and rear arcuate portions having front and rear end portions coupled with the lower seat. The front arcuate portion is spaced from the front upper edge by a front spacing. The rear arcuate portion is spaced from the rear upper edge by a rear spacing. The front and rear spacings permit elastic deformation of the at least one elastic element.

Abstract: An angular position adjusting device includes a coupling column coupled with a chair body. The coupling column includes a top end having a lower coupling face with a receiving groove, a pivotal groove, and at least one restraining groove. The pivotal groove includes a bottom wall having a coupling hole. A positioning block is mounted in the receiving groove and includes a resilient portion having a positioning member. A seat includes a lower end having an upper coupling face with an axle received in the pivotal groove. A fastener extends through the axle and is coupled with the coupling hole of the coupling column. The positioning member is selectively and releasably engaged in one of angularly spaced positioning grooves of the upper coupling face. At least one restraining member is disposed on the upper coupling face and is slidably received in the at least one restraining groove.

Abstract: A bedside dining table includes a supporting beam mounted on top of a vertical leg. A table is mounted on a top of the supporting beam. First and second axle seats are coupled to the supporting beam. The first axle seat includes a plurality of angularly spaced positioning holes. First and second pivotal seats are coupled to the table. Two axles respectively extend through axle holes of the first and second pivotal seats and the first and second pivotal seats to permit pivotal movement therebetween. Each of the first and second pivotal seats includes an arcuate abutment face abutting an arcuate abutment face of one of the first and second axle seats. A positioning seat is mounted to the first pivotal seat. A positioning rod extends through the positioning seat and is biased by an elastic element into one of the plurality of positioning holes of the first axle seat.

Abstract: A forearm crutch includes a supporting rod, a handle, and a holding device. The supporting rod is adapted to contact with ground. The supporting rod includes an upper end having a holding portion. The handle is mounted below the holding portion and extending forward. The holding device includes two holding plates and two elastic elements. The two holding plates are respectively mounted to two sides of the holding portion. Each of the two elastic elements is coupled between one of the two holding plates and the coupling portion to provide the two clamping plates with a holding force relative to the holding portion for holding a forearm of a user.

Abstract: An improved chair is disclosed. The chair includes: (i) a seat; (ii) a base portion connected to the bottom of the seat; (iv) an upwardly extending support frame connected to either the seat or the base; and (v) a backrest connected to the support frame by a number of fasteners. The fasteners include a resilient member located between the backrest and the support frame, such that the backrest is spaced apart from the support frame.
