FIG. 1 is a view illustrating a state of use of a detachable structure of a tray and a tent frame of a tricycle according to an embodiment of the present invention, and FIG. 2 is a sectional view of a structure of a tray and a tent frame of a tricycle, according to an embodiment of the present invention. 3A to 3C show an operational sectional view of a detachment structure of a tray and a tent frame of a three-wheeled bicycle according to an embodiment of the present invention, and Figs. 4A to 4C are views showing an operation sectional view of an embodiment of the present invention Sectional view of a tray and a detachment structure of a tent frame according to a third embodiment of the present invention.

According to a preferred embodiment of the present invention, a tray and a tent frame are detachably mounted on a frame of a tricycle and are installed at both ends of the installation frame, A detachable bracket detachably coupled to the first insertion port and having a tent on an upper portion thereof; and a support bracket detachably mounted on the first insertion port, A pressing member which is provided on a side surface of the detachable bracket and controls the detachment of the support frame according to whether or not the pressing frame is pressed; insertion projections are protruded from the bottom surfaces of both ends so that both sides thereof are detachably coupled A tray provided at a center thereof with a receiving part; And a detachment switch in which detachment of the tray is controlled is included.

Hereinafter, the structural members of the detachment structure of the tray and the tent frame of the three-wheeled bicycle according to the preferred embodiment of the present invention and the operation thereof will be described in detail with reference to FIGS. 1 to 4C.

Here, the installation frame 10 serves to fix the constituent members to be described later on the frame of the tricycle, and is installed on the tricycle in the "U" shape and the direction, and both ends thereof are positioned upward.

The detachable bracket 20 is detachably coupled to both ends of the mounting frame 10. The detachable bracket 20 is detachably coupled to the support frame 30 and the tray 50 to be described later It plays a role. The attachment / detachment bracket 20 is formed with a fastening protrusion 21 connected to the mounting frame 10 on the lower side thereof, a first insertion opening 22 formed on the upper side thereof, and a second insertion opening 23 formed on the front side thereof Respectively. At this time, a fastening hole 22a is formed in the inner surface of the first insertion port 22 to selectively receive and release the elastic pin and the detachment protrusion 41 to be described later.

The support frame 30 is detachably coupled to the first insertion port 22. The support frame 30 serves to provide a tent 31 on the support frame 30, And is formed into a bar shape. Inside the lower end of the support frame 30, there is provided an elastic pin 32 elastically received in the fastening hole 22a.

The side surface of the above-described detachable bracket is provided with a pressing member 40. The above-described pressing member 40 serves to control the detachment of the support frame 30 according to whether the pressing member 40 is pressed or not. The pressing member 40 is provided with a detachment protrusion 41 protruding and retracted into and out of the fastening hole 22a described above. The detachment protrusion 41 is formed inside and outside the fastening hole 22a in the direction opposite to the elastic pin 32 And the attachment / detachment of the support frame 30 is controlled.

That is, when the support frame 30 is inserted into the first insertion port 22 and the resilient fins 32 are elastically biased and inserted into the fastening holes 22a by the self-elasticity, the fastening holes 22a 41 are pushed, but the pressing member 40 is moved outwardly. In this state, when the pressing member 40 is pressed inward, the detachment protrusion 41 enters the inside of the fastening hole 22a, the elastic pin 32 is released from the fastening hole 22a, And can be separated within the first insertion opening 22.

In the meantime, both ends of the tray 50 are detachably coupled to the second insertion port 23. The tray 50 functions as a table and prevents the occupant from falling off the seat will be.

The tray 50 is fastened to the second insertion opening 23 side in the shape of " ⊂ ". The insertion protrusion 51 inserted into the second insertion opening 23 is protruded from the bottom surface of both ends of the tray 50, A receiving portion 52 for placing a toy or a snack therein is formed at the center thereof and a fastening step 51a is formed at a front lower side of the insertion protrusion 51. [

The detachment switch 60 is provided at one side of the insertion protrusion 51. The detachment switch 60 described above is supported by the coupling step 51a and inserted into the second insertion hole 23, Thereby preventing a sudden departure. Such a detachment switch 60 is resiliently supported on the side of the fastening step 51a at the same time that the insertion projection 51 is completely inserted into the second insertion opening 23 and is separated from the fastening step 51a when pressed.

The insertion protrusions 51 are inserted into the second insertion ports 23 at the time of coupling the tray 50 and then pressed down from the upper side to the lower side until the release switch 60 is supported by the coupling step 51a, When the tray 50 is detached, the detachment switch 60 is pulled from the lower side to the upper side in the pressurized state.

As the present invention can be variously modified by those skilled in the art without departing from the scope of the claims claimed in the scope of the utility model registration, the technical protection scope of the present invention is not limited to the specific preferred embodiments But is not limited to the example.
