Abstract
The horizontally-folded frame of baby carriage whose bearing bar and underbed can be separated includes front wheels, rear wheels, underbed, active four-bar linkage mechanism, supporting bar, bearing bar and handlebar, in which the lower end of the supporting bar is hinged to the underbed, and its upper end is hinged to the front portion of the four-bar linkage mechanism, and the upper end of the bearing bar is fixedly joined together with the front link of the four-bar linkage mechanism, and its lower end can be separated from the underbed, and can be fastened to the underbed by means of elastic locking mechanism.
Description
The present invention relates to frame for baby cart, the horizontal folding type baby carriage frame that specifically a kind of bearing bar and base can be thrown off.
In existing horizontal folding baby carrier frame, initiatively four connecting rods utilize driven four connecting rods and underframe to link, and as described in CN2118676U, its driven four connecting rods are by forward and backward bearing bar, and the front rod in base and active four connecting rods constitutes.When baby carriage frame is in open configuration, front rod and the preceding bearing bar shape that is in line, driven four connecting rods become a big triangle.This structure has certain stability after baby's bedstead being rested on active four connecting rods.But because in this structure, front rod connects for movable with preceding bearing bar, therefore, so-called big triangle is actually the triangle of a vacation, between front rod and preceding bearing bar, one hinge-point is arranged, increased required connector, also just increased work capacity and productive costs when producing.
The objective of the invention is to design the affixed all-in-one-piece horizontal folding type baby carriage frame of a kind of front rod and bearing bar, with further raising stability, cost-cutting.
Its main technical schemes comprise be installed in before, arc-shaped base on the trailing wheel, and be positioned at base top by preceding, after, on, the active four-bar linkage that lower link constitutes, on rear linking rod, be connected with handspike, connect strut bar at boxed rod with the union end of front rod, the lower end of this strut bar is hinged on the rear portion of base, the two ends of joystick are hinged on respectively on rear linking rod and the strut bar, there is bearing bar lower end at front rod, and, front rod becomes to be fixedly connected with bearing bar, the lower end of bearing bar can be thrown off with base, and the elastic locking mechanism that can lock bearing bar is arranged in the contact position of base and bearing bar; The lower end of the fork in this elastic locking mechanism is hinged on the front end of base, is connected with spring and hook on the fork, and the other end of spring connects with base, and the pin that can cooperate with hook is arranged in the bearing bar lower end; Perhaps, the fork in the elastic locking mechanism is hinged on the lower end of bearing bar, is connected with pin and spring on fork, connect on the base can with the hook of pin fit on the fork.Described elastic locking mechanism also can adopt the lock structure of lever lock tongue of locating bush.During installation, locating bush is fixed in the front end of base, side at locating bush has transverse groove, place the locking bar that is with spring in the groove, the inner of locking bar is a dead bolt, and the outer end is a shank of the key, and the inner of spring contacts with dead bolt, the outer end contacts with lid on being fastened on locating bush, and the hole that can cooperate with dead bolt is arranged in the lower end of bearing bar.Another form of elastic locking mechanism is that an end of L shaped buckle is hinged on the base, the movable end of buckle has the hook that can hook the bearing pin that is connected in the bearing bar lower end, also affixed baffle plate on base, middle part at buckle connects handle, one end of spring is connected in the middle part of buckle, the other end is connected on base or the baffle plate, and the gap that can allow bearing bar insert is arranged between baffle plate and buckle.
Advantage of the present invention is owing to front rod and bearing bar is affixed is integral, when vehicle frame is in open configuration, strut bar, bearing bar and base constitute a real stable big triangle, and the lower end of bearing bar is also highly stable under the effect of elastic locking mechanism.Therefore, thoroughly stopped the vibration problems that caused because of the hinge-point between front rod and preceding bearing bar originally, made whole vehicle frame have the stability of real meaning.Secondly,, reduced the articulation piece between a cover rod member, also just reduced the trouble point that may occur, reduced required raw MAT'L and machining period especially in process of production, reduced cost with original comparing.After being installed in lockout mechanism between rear linking rod elongated end and joystick originally and being installed between base front end and the bearing bar lower end, make installation baby carrier and tent part thereof seem fairly simple, and not corpulent loaded down with trivial details, thereby, also help the installation and the maintenance of each several part member.
Constitution diagram when Fig. 1 opens for the present invention is in.
Fig. 2 is folding process figure.
Constitution diagram when Fig. 3 will finish for folding.
Fig. 4 is an another kind of elastic locking mechanism.
Fig. 5 is another elastic locking mechanism.
As shown in Figure 1, 2, 3: the following installation front and rear wheel 8,10 of arc-shaped base 9, and in the position of relative front and rear wheel 8,10 connection strut bar 11 and elastic locking mechanism.Initiatively four-bar linkage is by forward and backward, upper and lower connecting rod 4,13,2,3 hinged forming, the upper end of strut bar 11 is hinged on the hinged place of boxed rod 2 and front rod 4, upper end at rear linking rod 13 connects handspike 1, at rear linking rod 13 and 11 hinged joysticks 12 of strut bar, this joystick 12 is used for interlock and supporting role, front rod 4 and bearing bar 14 affixed being integral.
The fork 6 of elastic locking mechanism is hinged on the base 9, and the top of fork is connected with spring 7 and hook 5, this hook 5 can with the pin fit that is connected in bearing bar 14 lower ends, the other end of spring 7 is connected on the base 9.As another kind of form, also hook 5 can be connected in bearing bar 14 lower ends, bearing pin is installed on the fork 6.
The another kind of pattern of elastic locking mechanism is a welding locating bush 15 on base 9, one transverse groove 20 is arranged on locating bush, place the locking bar 18 that is with spring 21 in the groove, one end of locking bar connects dead bolt 17, the other end connects shank of the key 19, one end of spring 21 contacts with dead bolt 17, and the other end contacts with the lid 22 that is installed in transverse groove 20 ends.Bearing bar 14 can insert in the locating bush 15, and the hole 16 that can cooperate with dead bolt 17 is arranged in the lower end of bearing bar 14.See Fig. 4.
Elastic locking mechanism also can adopt structure as shown in Figure 5.Respectively affixed baffle plate 23 and hinged L shaped buckle 26 on base 9, the movable end of buckle has the hook that can hook the bearing pin 25 that is connected in the bearing bar lower end, the middle part is connected with handle 24, one end of spring 27 is connected in the middle part of buckle 26, the other end is connected on base 9 or the baffle plate 23, at baffle plate 23 and 26 of buckles the gap 28 that can allow bearing bar 14 insert is arranged.
