Description

ELASTIC DEVICE OF A hINGE The present invention relates to an elastic
device of a hinge, in particular to one having a U-shaped leaf spring secured in an accommodation of a hinge cup to provide a restoring force to the hinge.
Hinges have been widely applied to furniture. The basic design includes a hinge cup, a hinge arm and a fixture. The hinge arm is pivotally connected to the hinge cup in a swiveling manner. The hinge cup is usually secured to a cabinet door. A resilient element is located in the hinge cup to provide a restoring force to the hinge arm in order to pull the cabinet door back and close the cabinet.
Most of the conventional resilient elements are made in a spring, such as U.S. Patent Nos. 5,604,956; 5,617,612; 6,393,663 Bi; 6,477,737 B2; 6,845,544 B2; and 6,880,205 B2. Another type of the resilient element is made in a leaf spring, such as U.S. Patent No. 6,360,401 Bi.
The above-mentioned resilient elements are designed to meet different hinges, however, all of these types of hinges have a short service life time.
The present invention is to provide an elastic device of a hinge, which solves the compromise problems between a hinge ann and a hinge cup upon the hinge is closed so as to provide a steady restoring force to the hinge.
According to the present invention, there is provided an elastic device of a hinge comprising a hinge cup, a hinge arm, a connecting pivot, and a leaf spring, wherein said hinge cup has an accommodation and said hinge arm has a cam section secured in said accommodation by said connecting pivot, and characterized by: said leaf spring being a U-shaped plate having a fixed section at one end and a tongue at another end, said fixed section being flush with the bottom of said accommodation of said hinge cup, the bottom of said accommodation being provided with fixing pieces to engage with said fixed section and secure said fixed section in place, said hinge arm being disposed with a slot adjacent to said cam section, said tongue of said leaf spring extending through said slot and being against said cam section of said hinge arm.
Preferably, the bottom of said accommodation of said hinge cup is provided with restraining studs; said restraining studs and said fixing pieces engage with said fixed section; said fixing pieces are bent to secure said fixed section in place.
Preferably, said restraining studs on the bottom of said accommodation correspond to and engage with the edge of said fixed section.
Preferably, said fixed section of said leaf spring is formed with holes for insertion of said restraining studs.
Preferably, the bottom of said accommodation is provided with openings and said fixing pieces; said fixed section of said leaf spring is provided with restraining studs to be inserted through said openings; said fixing pieces are bent to secure said fixed section in place.
Preferably, said fixed section of said leaf spring is formed with locating holes; the bottom of said accommodation of said hinge cup is provided with said fixing pieces; said fixing pieces extend through said locating holes and are bent to secure said fixed section in place.
It is the primary advantage of the present invention to provide an elastic device of a hinge, which comprises a U-shaped leaf spring to provide a long service life time.
It is another advantage of the present invention to provide an elastic device of a hinge, which has an adequate space between the leaf spring and the accommodation of the hinge cup to allow the hinge arm to be inserted therein.
There now follows a description of preferred embodiments of the invention, by way of non-limiting example, with reference being made to the accompanying drawings in which: Figure 1 is an exploded view of a first embodiment of the present invention; Figure 2 is a perspective view of the first embodiment of the present invention; Figure 3 is a side cross-sectional view of the first embodiment of the present invention in a collapsed status; Figure 4 is a side cross-sectional view of a second embodiment of the present invention; Figure 5 is a side cross-sectional view of a third embodiment of the present invention; Figure 6 is a side cross-sectional view of a fourth embodiment of the present invention.
As shown in Figure 1, a first embodiment of the present invention comprises a hinge cup 1, a hinge arm 2, a connecting pivot 3 and a leaf spring 4. The hinge cup 1 has an accommodation 11. The hinge arm 2 has a cam section 21 which is secured in the accommodation 11 by the
S
connecting pivot 3.
The bottom of the accommodation 11 of the hinge cup 1 is provided with fixing pieces 12 and restraining studs 13.
The hinge arm 2 is disposed with a slot 22 adjacent to the cam section 21.
The leaf spring 4 is a U-shaped plate which has a fixed section 41 at one end and a tongue 42 at the opposite end thereof.
To operate the present invention, as shown in Figures 2 and 3, the leaf spring 4 is placed into the accommodation 11 of the hinge cap 1, and the fixed section 41 of the leaf spring 4 is flush with the bottom of the accommodation 11 of the hinge cup 1. The tongue 42 extends through the slot 22 of the hinge arm 2 and is against the cam section 21. The restraining studs 13 provided on the bottom of the accommodation 11 engage with one side of the fixed section 41 of the leaf spring 4, while the fixing pieces 12 are bent to engage with the other side of the fixed section 41.
When the hinge is collapsed, as shown in Figure 3, the hinge arm 2 --will be moved towards the accommodation 11 of the hinge cap 1 and be located above the leaf spring 4.
Figure 4 shows a second embodiment of a hinge cup La and a leaf spring 4a of the present invention. A fixed section 41 a of the leaf spring 4a is formed with holes 41 la for insertion of restraining studs 1 3a provided on the bottom of an accommodation 11 a of the hinge cup 1 a, while fixing pieces 1 2a provided on the bottom of the accommodation 11 a are bent to engage with the edge of the fixed section 41 a.
Figure 5 shows a third embodiment of a hinge cup lb and a leaf spring 4b of the present invention. The hinge cup lb has an accommodation lib. The bottom of the accommodation lib is formed with openings ilib. A fixed section 41b of the leaf spring 4b is provided with restraining studs 41 2b to be inserted through the openings 111 b, while fixing pieces I 2b provided on the bottom of the accoimnodation lib are bent to engage with the edge of the fixed section 41 b.
Figure 6 shows a fourth embodiment of a hinge cup i c and a leaf spring 4c of the present invention. A fixed section 41c of the leaf spring 4c is formed with locating holes 413c. The hinge cap Ic has an accommodation 11 c. The bottom of the accommodation 11 c is provided with fixing pieces 12c. The fixing pieces 12c extend through the locating holes 413c of the leaf spring 4c arid are bent to secure the leaf spring 4c in place.
