Abstract
A modified structure of a telescopic belt buckle includes a spring compartment in the belt buckle body, and a latch located at the end of the spring to link the head of the belt, which is allowed to slide along the compartment and reach the belt fastening the human body with specific length for extension. As both the thickness of the belt equals the space taken by the spring, the compartment is thus provided with enough space for telescopic movement of the most slim and simple buckle.

FIELD OF THE INVENTION




The present invention relates to a telescopic belt buckles. More particularly, the present invention relates to a telescopic belt buckle in which a compartment in the belt buckle conceals a small piece of a tip of the belt so as to receive a spring that allows the belt to telescope within this compartment.




BACKGROUND OF THE INVENTION




Conventional belts come in a fixed length. After the belt is positioned around the waist of the user, this fixed length tends to be unexpandable with the flexible movements of the human body. The waist size of any given person can vary slightly over the course of a single day. The difference in waist size before and after a meal can be noticed. Some persons will feel slightly uncomfortable with a tightly fastened belt. As a result, adjustment of the belt is necessary.




In the past, a large number of telescopic belt buckles have been developed. Virtually all of these telescopic belt buckles have the belt buckle fixed at one end of the belt while a spring, along with other elements, are also included in the belt so as to allow the belt to be expandable. In particular, there is a sliding and hooking block used to latch the hole at the end of the belt. The entire assembly of the hook slides and allows the belt to move freely. Those prior art telescopic belt buckle that are available in the marketplace are mostly of a very complicated structured and are positioned at the end of the belt. As a result, the telescopic belt buckle is not compact, nor is it elegant.




The telescopic belt buckle of the present invention has a moving tip positioned at the beginning of the belt and not at the end of the belt. A small piece of the tip is concealed in the compartment of the belt buckle. This piece of the tip is joined to a spring so as to allow the space of the compartment to be fully used. The other elements, such as the latch and the fastening ring of the belt, remain fixed as used in conventional belts. Since the space in the compartment of the belt buckle is optimally used, the assembly of the present invention is simplified and lightweight. As a result, the buckle is more compact. This compact belt buckle will be satisfactory to most users' preferences.




BRIEF SUMMARY OF THE INVENTION




The present invention is a belt for men. The end of the belt is concealed within the buckle. The present invention also relates to a modified telescopic belt buckle that has the front end of the belt buckle attached with a ring. On the top of the ring, there is a latch or a pin in the center thereof that allows the hole at the end of the belt to be latched through the notch in the center of the ring prior to winding up above the belt buckle.

is placed across an inside surface of the buckle unit


1


. The cover


2


has a protruding latch


24


. The belt


4


has a belt head


41


which passes through the belt ring


14


at one end of the buckle unit


1


while the other end


42


of the belt


4


winds up onto the opposite end of the buckle unit


1


. As a result, a circular belt


4


is formed.





FIG. 2

shows the interior construction of the buckle unit


1


. The buckle unit


1


has a hollowed compartment


11


in an interior thereof. The belt ring


14


defines the exit of the hollowed compartment


11


. The opposite end of the compartment


11


includes a spring unit


3


in the form of plate winding springs


31


and


32


. The plate winding springs


3


land


32


are secured to the buckle unit


1


. A cradle


33


extends from the spring unit


3


and is positioned against a bottom of the compartment


11


. The belt head


41


is received within the compartment


11


. The end of belt head


41


is engaged with the cradle


33


so as to allow free horizontal movement within the compartment


11


. The cover


2


is placed over the spring unit


3


and across the compartment


11


. The cover


2


divides the end of the belt ring


14


so as to allow the formation of the exit of the belt head


41


and an entry for the tip end


42


of the belt


4


.

FIG. 3

shows these elements in greater detail.




The buckle unit


1


is in the form of an elongated block with a back surface defining an interior portion of the compartment


11


. Studs


12


and


13


protrude from back surface of the compartment


11


. Each of the studs


12


and


13


include screw holes which allow screws to be secured thereto. The end of the buckle unit


1


, defining the exit of the compartment


11


, is in the form of an inverted block “U” configuration that extends outwardly so as to form the belt ring


14


. A pair of pin holes


15


are formed on the opposite sides of the belt ring


14


. The spring unit


3


includes a pair of winding springs


31


and


32


. The centers of each of the winding springs


31


and


32


are fitted onto the studs


12


and


13


such that the studs


12


and


13


act as an axle cam for the pair of winding springs


31


and


32


. One end of the pair of winding springs


31


and


32


is connected to the L-shaped cradle


33


. One surface of the cradle


33


is positioned against the inside surface of the compartment


11


. The cradle


33


has pins


331


and


332


protruding therefrom. The holes


411


and


412


on one end of the belt


41


are secured to the pins


331


and


332


. The cover


2


is an elongated plate that has a latch


24


protruding from an outer surface thereof. Screw holes


22


and


23


are formed adjacent to the latch


24


so as to align with the studs


12


and


13


. Pin holes


21


are formed at the outer edges of the cover


2


. A pair of straight pins


5


engage the pin holes


15


of the plate and engage the pin holes


21


of the cover


2


. Screws


6


pass through the screw holes


22


and


23


so as to secure the cover


2


onto the buckle unit


1


and into the studs


12


and


13


.





FIGS. 4A-C

show the assembled structure. The compartment


11


of the buckle unit


1


has springs


31


and


32


, along with the cradle


33


, engaged with the end of the belt


4


. The cradle


33


has pins


331


and


332


engaged with the holes


411


and


412


in the head


41


of belt


4


.The belt is inserted through the right exit at the belt ring


14


of the compartment


11


. The cover


2


closes the hollowed out compartment buckle unit


1


. The right end of the cover


2


is secured into the pin hole


15


by straight pins


5


. This allows the belt ring


14


to form a guide for the end


42


of the belt


4


. The belt end


42


can include a plurality of latch holes


43


so as to allow for the free setting onto the latch


24


on cover


2


by the user. As can be seen in

FIG. 4B

, the assembled belt


4


is withheld by the springs


31


and


32


from the belt end


41


for rightward extension and restoration (as shown in

FIG. 4C

) within a limited range. This allows the belt to have elasticity when latched.

A. The latch


7


A has a retaining latch


74


A. The latch


7


A also has security pin


8


A that is engaged into the latch hole


43


A at the end of the belt


4


A. This allows the belt end


42


A to pass through the latch


7


A before being positioned against the buckle unit

3


in the buckle unit


1


A which guides the belt head for automatic adjustment within a specific length.




The present invention has the free end of the belt as a part of the belt head without void spaces. The free end is fully concealed into the belt buckle unit. During telescopic movement, the elements remain free from movement along with the user's body or clothing. The simple construction provides convenient manufacture, low cost and a desirable appearance.




The foregoing disclosure and description of the invention is illustrative and explanatory thereof. Various changes in the details of the illustrated construction can be made within the scope of the appended claims without departing from the true spirit of the invention. The present invention should only be limited by the following claims and their legal equivalents.
