Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 14/327,678 filed Jul. 10, 2014, which claims
priority to Chinese Patent Application No. 201410062294.0 filed
Feb. 24, 2014, the contents of which are incorporated herein by
reference in their entirety
FIELD OF THE INVENTION
[0002] The present invention relates to a recreational vehicle, in
particular the recreational vehicle capable of adjusting the width
of a front wheel or a rear wheel that touches the ground to improve
the variability, adaptability and practicality of the vehicle.
BACKGROUND OF THE INVENTION
[0003] In general, children are helped by others to support their
balance or auxiliary wheels are installed on both sides of a rear
wheel to achieve the learning purpose when the children learn how
to ride a vehicle. However, such arrangement can only achieve the
effects of stabilizing a vehicle body and preventing the children
from falling down from the vehicle, but it has not much practical
help on the effect of learning how to ride a vehicle sooner. On the
contrary, children may even become psychologically dependent over
time and fail to develop the potential of maintaining their
balance.
[0004] Therefore, a recreational vehicle (also known as a slider or
walker) without any pedals or chain is introduced into the market.
Basically, the recreational vehicle comprises a front fork
installed at the front of a frame for connecting a handlebar and a
front wheel, a rear wheel installed at the other end of the frame,
a seat installed at the middle section of the frame and provided
for a rider to sit thereon, so that the rider can hold the
handlebar by both hands and stomp at the ground by both legs to
push the front wheel and rear wheel to rotate in order to drive the
recreational vehicle forward and train the children's muscle
strength and balance.
[0005] In a conventional recreational vehicle, both front and rear
wheels are single wheels, so that the wheels can slide by touching
the tire tread of each wheel on the ground. To provide flexible
control and operability, the width of the tire tread of each wheel
is substantially equal to the width of the tire of a general
children's vehicle, and the tire tread of the wheel is not
adjustable, so that the level of difficulty of the learning is
still very high. As to a younger child, the learning and practice
are relatively more difficult and dangerous, and such recreational
vehicle reduces the adaptability and practicality significantly. In
applications where it is desired to more securely fix the position
of one pivot member to another in a pivot joint, the locking faces
of the pivot members are furnished with complementary teeth/deeply
inclined ridges that define a number of relative rotational
orientations in which the first and second pivot members can be
fixed relative to one another.
SUMMARY OF THE INVENTION
[0006] Therefore, it is a primary objective of the present
invention to provide a recreational vehicle capable of adjusting
the width of a front wheel or a rear wheel that touches the ground
to improve the variability, adaptability and practicality of the
vehicle.
[0007] To achieve the aforementioned objective, the present
invention provides a recreational vehicle having a seat installed
at the middle section of a frame, a front wheel set and a rear
wheel set installed at the front and the rear of the frame
respectively and provided for touching the ground, and a handlebar
installed at the front of the frame, characterized in that the
recreational vehicle comprises two parallel wheels installed to the
front wheel set or the rear wheel set, wherein the axes of the two
wheels are not configured to be aligned on the same horizontal
line, and the two wheels are installed at the frame through an
adjusting module that is movable with respect to the frame, and a
fixing module is installed between the frame and the adjusting
module for controlling whether to move the adjusting module with
respect to the frame.
[0008] With the aforementioned characteristics, the recreational
vehicle of the present invention has the wheels of the front wheel
set or rear wheel set whose axes are not configured to be aligned
on the same horizontal line, so that a user can select a side of
the two wheels with a greater tire tread spacing or a side of the
two wheels with a smaller tire tread spacing to touch with the
ground by the effect of the fixing module. Therefore, the stability
of the vehicle body can be enhanced to help younger children to
learn how to ride the vehicle when the side of the two wheels with
a greater tire tread spacing is in contact with the ground or the
flexibility of riding the vehicle can be maintained to provide more
fun to the ride when the side of the two wheels with a smaller tire
tread spacing is in contact with the ground.
[0009] Specifically, the recreational vehicle of the present
invention has the following advantages and effects:
[0010] 1. A user can adjust the width of the wheel set that touches
the ground according to the user's age and riding skill, and thus
the invention provides a more practical and safe ride.
[0011] 2. The recreational vehicle of the invention can satisfy the
requirements of children of different ages, and thus the invention
provides better adaptability.
[0012] 3. The whole recreational vehicle can be erected for parking
or storage by setting the two wheels with a greater tire tread
spacing of the rear wheel set to be touched with the ground, and
thus the invention improves the convenience of use.

the rear wheel set, and the axes of the two wheels 52 are not
configured to be aligned on the same horizontal line, and the two
wheels 52 are installed at a rear end of the frame 10 through an
adjusting module 60 that can move with respect to the frame 10, and
a fixing module 70 installed between the frame 10 and the adjusting
module 60 for controlling whether to move the adjusting module 60
with respect to the frame 10. In other words, the two wheels 52 of
the rear wheel set have the downwardly tapered or upwardly tapered
effect under the action of the adjusting module 60, and the fixing
module 70 is provided for keeping the two wheels 52 of the rear
wheel set at the downwardly tapered or upwardly tapered
condition.
[0025] Of course, the front wheel set may have two parallel wheels
(not shown in the figure), and the two wheels of the front wheel
set can be fixed to a downwardly tapered or upwardly tapered
condition through the adjusting module and the fixing module for
its use.
[0026] In a preferred embodiment as shown in FIGS. 1 to 6, the
frame 10 has a circular slot 13 transversally formed at the rear
end of the frame 10, and the fixing module 70 has a hoop 71 set
into the circular slot 13 and movable in the circular slot 13, and
a pull rod 72 passing from an outer side of the frame 10 through a
wall of the circular slot 13 and coupled to the hoop 71, wherein a
cam wrench 73 is installed at a rear end of the pull rod 72 for
dragging the pull rod 72 to move reciprocally in an axial
direction.
[0027] The adjusting module 60 has a shaft member 61 installed into
the hoop 71 and rotatable in the hoop 71, and a hub 62 disposed
separately at both ends of the shaft member 61 for installing the
wheel 52, wherein the axes of the two hub 62 are not set to align
with the same horizontal line; and the shaft member 61 can be
dragged together with the hoop 71 by the cam wrench 73 and the pull
rod 72, and the shaft member 61 is pressed against the circular
slot 13 and unable to rotate, or the shaft member 61 is not pressed
against the circular slot 13 and capable of changing a rotating
status.
[0028] The frame 10 has a circular slot 13 formed at a rear end of
the frame 10, and the fixing module 70 has a hoop 71 set into the
circular slot 13 and displaceable in the circular slot 13, and a
pull rod 72 passing from an outer side of the frame 10 through a
wall of the circular slot 13 and coupled to the hoop 71, and the
pull rod 72 has a cam wrench 73 installed at a rear end of the pull
lord 72 for dragging the pull rod 72 to move reciprocally in an
axial direction, and the adjusting module 60 has a shaft member 61
set into the hoop 71 and rotatable in the hoop 71, and a hub 62 is
installed separately at both ends of the shaft member 61 for
installing a wheel 52, and the axes of the two hubs 62 are not
configured to be aligned on the same horizontal line; and the shaft
member 61 is dragged together with the hoop 71 by the cam wrench 73
and the pull rod 72, so that the shaft member 61 is pressed against
the circular slot 13 and cannot rotate, or not pressed against the
circular slot 13 to allow a change of the rotating status. The
adjusting module 60 further has a bushing 63 disposed separately at
the positions where the shaft member 61 is extended out from both
sides of the hoop 71 and rotatable with the shaft member 61 in the
circular slot 13, and the bushing 63 and the circular slot 13 abut
against each other to produce a fixing effect to restrict them from
rotating.
[0029] In the foregoing preferred embodiment, the adjusting module
60 comprises a knob 64 installed on an outer side of one of the
wheels 52 of the rear wheel set and fixed to the hub 62 of the
wheel 52 and rotatable with the shaft member 61, so that the fixing
module 70 may be released from the restriction with the shaft
member 61 and the knob 64 may be turned direction to adjust the two
wheels 52 of the rear wheel set in a downwardly tapered status (as
shown in FIG. 6) or an upwardly tapered status (as shown in FIG.
7).
[0030] Since the recreational vehicle of the present invention has
two wheels installed at the front wheel set or the rear wheel set
and having two axes not configured to be aligned on the same
horizontal line, therefore users can select a side of the two
wheels with a greater tire tread spacing a side of the two wheels
with a smaller tire tread spacing to be in contact with the ground
under the effect of the fixing module, such that when the side of
the two wheels with a greater tire tread spacing is in contact with
the ground, the stability of the vehicle body is enhanced to assist
younger children to learn how to ride the vehicle, and when the
side of the two wheels with a smaller tire tread spacing is in
contact with the ground, the flexibility of riding can be
maintained to provide more fun to the ride.
[0031] In the foregoing preferred embodiment, the shaft member 61
has a first straight section 611 disposed at opposite positions of
an outer periphery of the shaft member 61 (wherein the included
angle of the two first straight section 611 is equal to
180.degree.), and the hoop 71 has a second straight section 711
disposed at an inner periphery of the hoop 71 and opposite to the
other side coupled to the pull rod 72 for pressing against any one
of the first straight sections 611, so that the rotation of the
shaft member 61 with respect to the hoop 71 is limited by the
pressing effect of the first straight section 611 and the second
straight section 711 to achieve a more stable and reliable fixing
effect.
[0032] The adjusting module 60 has a bushing 63 disposed separately
at positions of the shaft member 61 that is extended out from both
sides of the hoop 71 and rotatable together with the shaft member
61 in the circular slot 13, and the whole recreational vehicle 10
has a groove 631 formed at an outer periphery of one of the
bushings 63 for limiting the rotating angle (180.degree.) of the
shaft member 61, and at least one bump 131 formed at an inner
periphery of the circular slot 13 of the frame 10 for extending
into the groove 631. With the effect of the bump 131 and the groove
631, users can quickly identify whether or not the shaft member 61
has rotated to a fixed position, and a better operation hand feel
is provided.
[0033] Of course, the adjusting module 60 of the recreational
vehicle has a bushing 63 installed onto the shaft member 61 and at
position of extending out from both sides of the hoop 71 and
rotatable in the circular slot 13 of the frame 10, wherein at least
one of the bushing 63 has a groove 631 formed at the outer
periphery of the bushing 63 for restricting the rotating angle
(180.degree.) of the shaft member 61, and at least one bump 131
formed at the inner periphery of the frame 10 for extending into
the groove 631; and the adjusting module 60 preferably includes a
knob 64 installed on an outer side of one of the wheels 52 of the
rear wheel set and coupled to the hub 62 that is installed at the
wheel 52 and rotatable together with the shaft member 61.
[0034] The adjusting module 60 has a bushing 63 installed onto the
shaft member 61 and at position of extending out from both sides of
the hoop 71 and rotatable in the circular slot 13 of the frame 10.
The shaft member 61 has an anchoring groove 612 disposed around the
position where each bushing 63 is sheathed, and each bushing 63 has
an elastic hook plate 632 installed at the inner periphery of the
bushing 63 for latching into the anchoring groove 612. With the
latching of the elastic hook plate 632 with the anchoring groove
612, the positioning effect for preventing the bushing 63 from
slipping out is achieved.
[0035] In addition, the shaft member 61 has a first straight
section 611 disposed separately at two corresponding position of
the outer periphery of the shaft member 61 (wherein the included
angle of the two first straight sections 611 is equal to
180.degree.), and the hoop 71 has a second straight section 711
disposed at an inner periphery of the hoop 71 and opposite to the
other side coupled to the pull rod 72 for pressing against any one
of the first straight sections 611. The two bushings 63 further
include a third straight section 633 disposed at two corresponding
positions of the inner periphery of the bushing 63 and coupled to
the first straight section 611 of the shaft member 61 to enhance
the fixing effect for restricting the rotation of the shaft member
61.
[0036] In a preferred embodiment as shown in FIG. 7, the frame 10
has a stair 14 concavely formed at a rear end of the frame 10, and
the vertical wall of the stair 14 has a screw hole 141, and the
adjusting module 60 has two block 65 axially installed at the frame
10 and opposite to both sides of the stair 14 and swinging with
respect to the frame 10. Each block 65 has a hub 62 for installing
the wheel and positioning boards 651 stacked on one another and
attached to the vertical wall of the stair 14. The positioning
board 651 of each block 65 has a positioning through slot 652
aligned precisely with the screw hole 141 of the stair 14, and the
fixing module 70 has a bolt 74 passing through the positioning
through slot 652 of each block 65 and screwed into the screw hole
141 of the stair 14.
[0037] In a preferred embodiment as shown in FIG. 7, the bolt 74 of
the fixing module 70 is provided for pressing the positioning board
651 of the block 65 towards the vertical wall of the stair 14 of
the frame 10 to achieve the effect of fixing the angle of the axes
of the two wheels 52 of the rear wheel set. After the bolt 74 of
the fixing module 70 is loosened, the block 65 can be turned to
adjust the two wheels 52 of the rear wheel set to a downwardly
tapered status or an upwardly tapered status.
[0038] In a preferred embodiment as shown in FIG. 8, the frame 10
also has a stair 14 concavely formed at a rear end of the frame 10,
and a screw hole 141 formed on a vertical wall of the stair 14, and
the adjusting module 60 has two blocks 65 axially installed at the
frame 10 and opposite to both sides of the stair 14 and swinging
with respect to the frame 10, and each block 65 includes a hub 62
for installing the wheel, and positioning boards 651 stacked on one
another and attached onto the vertical wall of the stair 14, and
the positioning board 651 of each block 65 has a positioning
through slot 652 aligned precisely with the screw hole 141 of the
stair 14. The difference between this embodiment and other
embodiments resides on that the fixing module 70 has a bolt 75
passing through the positioning through slot 652 of each block 65
and screwed into the screw hole 141 of the stair 14, and the bolt
75 has a cam wrench 76 pivotally installed at a rear end of the
bolt 75, and the combination of the bolt 75 and the cam wrench 76
substitutes the design of the original single bolt to achieve the
effects of providing a quick release or pressing the positioning
board 651 of the block 65 towards the vertical wall of the stair 14
of the frame 10.
[0039] It is noteworthy that each preferred embodiment of the
present invention has two parallel wheels installed at the rear
wheel set (wherein the axes of the two wheels are not configured to
be aligned on the same horizontal line), or the front wheel set has
two parallel wheels (wherein the axes of the two wheels are not
