The specific embodiment
But the embodiment of the L shaped skeleton that folds of acute angle as shown in Figure 1, its support frame 2 comprises a lower supporter 21, a pair of oblique arm 22 and a pair of joint set 3.Wherein said lower supporter 21 is in order to kiss the earth and support described oblique arm 22, be provided with a pair of connecting portion 20 and a pair of grip part 24 in the upper end of described oblique arm 22, described connecting portion 20 can constitute a high chair with support frame 2 for connecting a seat support, also can connect an infant carrier and constitute a berch of baby, can connect a swing arm and seat again and constitute a swing (not shown) with support frame 2 is common with support frame 2 is common; In the present embodiment, described connecting portion 20 is mainly used to connect seat support or hand basket etc., and described connecting portion can be structures such as a detent or alignment pin, with convenient and seat support or hand basket etc.
As shown in Figure 2, described joint set 3 contains one first Connection Block 31, one second Connection Block 32, elastic parts 33, the first interlocking assembly 35 and one second an interlocking assembly 36.The described first interlocking assembly 35 and the second interlocking assembly 36 are connected to each other after running through first Connection Block 31 and second Connection Block 32, and its connected mode includes but not limited to the jelly gluing, with the thermal welding of ultrasonic machine, with the automatic clip joint of elasticity button or with the screw interlocking.First Connection Block 31 described in the present embodiment and second Connection Block 32 are example with 351,361 pairs of locks of screw thread, make described first Connection Block 31 and second Connection Block 32 remain on pivotable coupling access status.
Described first Connection Block 31 and second Connection Block 32 are respectively equipped with a connecting portion 311,321, are connected with described oblique arm 22 and lower supporter 21 respectively.The inner edge place of described second Connection Block 32 is provided with extension 322 and forms locating slot 323.Described first Connection Block, 31 inner edges are provided with a circle circular orbit 312 that is used for guiding extension 322.
As shown in Figure 3 and Figure 4, door bolt part 34 is installed on described oblique arm 22 lower ends slidably and passes the inside of described first Connection Block 31, has a latched position that snaps in the locating slot 323 of described second Connection Block 32, and described joint set 3 can't be rotated.Described elastic parts 33 is installed between door bolt part 34 and the oblique arm 22, makes described door bolt spare 34 remain in latched position, thereby makes described oblique arm 22 be fixed in the upright state of opening of an acute angle theta.
Please continue to consult Fig. 4 and Fig. 6, releasing device 5 is located at described oblique arm 22 upper ends, comprises an actuator 51 and a moving part 52.Wherein said actuator 51 can be a kind of actuators wherein such as rocking handle, sliding sleeve, rotary liner, knob or button, and described moving part 52 can be one kind of moving parts such as flexible wire, cable, steel cable.
Described actuator 51 can be contained in the position of close described grip part 24 with handled easily.It is to connect or butt with described moving part 52 that actuator is provided with 511 confessions of a connecting portion.Described moving part 52 is connected in door bolt part 34.When described actuator 51 is subjected to stopper, utilize moving of described connecting portion 511 to spur described moving part 52 and described door bolt spare 34 is detached its latched position in the mode of touching or affect, make described joint set 3 can recover to rotate.
As Fig. 6 and shown in Figure 7, when desire is adjusted the angle of oblique arm 22 or is carried out folding, the hand-holdable described grip part 24 of operator, make described door bolt spare 34 break away from described locating slot 323 with the described actuator 51 of thumb stopper simultaneously, when described joint set 3 is recovered to rotate, the hand-holdable described grip part 24 of user and control rotating up and down of described oblique arm 22 makes to change just angle or directly lower and draw close described lower supporter 21.
Fig. 8 has described a kind of alternate embodiment that discharges the mechanism in joint, and the mechanism 6 that wherein discharges the joint comprises a sliding sleeve 61 and a moving part 62.Wherein sliding sleeve 61 is socketed on the upper end of oblique arm 22 and is connected with moving part 62.When the user spurs described sliding sleeve 61, can described door bolt spare 34 be detached described locating slot 323, make described joint set 3 recover to rotate, thereby adjust the angle between described oblique arm 22 and the described lower supporter 21 by described moving part 62.
Again as shown in Figure 1, described lower supporter 21 is connected with the connecting portion 321 of second Connection Block 32 of joint set 3.Described lower supporter 21 can be the body of a bending, for example for the U-shaped pipe of a front end 215 and rear end 216 is arranged.The preferably can connect a transversal connecting assembly 211 between the both sides of described front end 215, to increase the structural rigidity of described lower supporter 21, prevent to take place when it is stressed transversely deforming.And slide in preventing to use, can install a plurality of on-slip assemblies 213,214 at the downside of described lower supporter 21, increase the frictional force of its bottom to ground.
Described oblique arm 22 is connected in the connecting portion 311 of first Connection Block 31 of described joint set 3, be to increase structural rigidity, can riveted joint, interlocking between two oblique arms 22 or weld a transversal connecting assembly 221, diagonal distortion takes place when bearing loading to prevent it.As Fig. 3, Fig. 4 and shown in Figure 6, articulate and angle orientation by joint set 3, make between described oblique arm 22 and the described lower supporter 21 and can keep an acute angle theta when the stationary state 100 that launches, (as shown in Figure 7) can directly down rely on the state 200 of described lower supporter 21 until complete folding again.
In sum, but L shaped skeleton acute angle of the present utility model folds its mode of operation ratio Known collapsible skeleton is convenient, has better practicality, novelty and creativeness.
