Buckle device for tightening strap

A buckle device for tightening a strap includes an opening formed in the middle portion for threading the strap. Two beams each includes two hooks engaged with the buckle device so as to be secured to the buckle device. The strap may be engaged through the buckle device and engaged with the beams before the beams are secured to the buckle device, such that the strap may be easily engaged through the buckle device.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a buckle, and more particularly to a 
buckle device for tightening a strap. 
2. Description of the Prior Art 
Typical buckles for tightening straps comprise a ring body having an 
extension radially extended inward therefrom for engaging with the straps 
to be tightened. The extension is solidly secured to the ring body and may 
not be disengaged from the ring body such that the strap may not be easily 
threaded through the ring body and engaged around the extension. 
The present invention has arisen to mitigate and/or obviate the 
afore-described disadvantages of the conventional buckles. 
SUMMARY OF THE INVENTION 
The primary objective of the present invention is to provide a buckle 
device in which the strap may be easily threaded and engaged in the buckle 
device. 
In accordance with one aspect of the invention, there is provided a buckle 
device for tightening a strap, the buckle device comprises a body 
including an opening formed therein for threading the strap, and at least 
one beam including hook means extended therefrom for engaging with the 
body so as to be secured to the body, the beam allowing the strap to be 
engaged thereon before the beam is secured to the body. 
The body includes two ends each having a groove formed therein for engaging 
with the hook means so as to secure the beam to the body. 
The buckle device includes two beams, the beams each includes a bottom 
surface having a plurality of ratchet teeth formed thereon, the body 
includes an upper surface having a plurality of ratchet teeth formed 
thereon for engaging with the ratchet teeth of the beams so as to prevent 
the beams from moving toward each other. 
Further objectives and advantages of the present invention will become 
apparent from a careful reading of a detailed description provided 
hereinbelow, with appropriate reference to accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring to the drawings, and initially to FIGS. 1 to 3, a buckle device 
in accordance with the present invention comprises a body 20 including an 
opening 21 formed therein and including two end portions each having a 
groove 23 formed in the side portion and each having a number of ratchet 
teeth 22 formed in the upper surface thereof. Two beams 30 each includes 
two hook means 33 extended downward from the end portions for engaging 
with the grooves 23 so as to be secured to the body 20, and each includes 
a number of ratchet teeth 32 formed in the bottom portion for engaging 
with the ratchet teeth 22 of the body 20. It is preferable that the beams 
30 have one end coupled together by a band 31 or the like. The strap 40 
includes two ends engaged through the body 20 and engaged around the beams 
30 respectively so as to be coupled together by the buckle device. It is 
to be noted that the strap 40 may be engaged through the opening 21 of the 
body 20 and engaged around the beams 30 before the beams 30 are secured 
onto the body 20, such that the strap 40 may be easily engaged with the 
buckle device. 
Referring next to FIG. 5, the engagement between the ratchet teeth 22, 32 
allows the beams 30 to move away from each other and prevents the beams 30 
from moving toward each other. 
Referring next to FIG. 4, alternatively, the beams 30 include hook means 35 
extended inward of the opening 21 of the body 20 for engaging with the 
body 20 so as to be secured to the body 20. 
Accordingly, the buckle device in accordance with the present invention 
includes a pair of beams that may be secured to the buckle body after the 
strap is engaged thereon such that the strap may be easily engaged with 
the buckle device. 
Although this invention has been described with a certain degree of 
particularity, it is to be understood that the present disclosure has been 
made by way of example only and that numerous changes in the detailed 
construction and the combination and arrangement of parts may be resorted 
to without departing from the spirit and scope of the invention as 
hereinafter claimed.
