Abstract

Disclosed is a soft-close device for a compact hinge comprising a housing removably fitted to the compact hinge and a plunger slidingly engaged with the housing. The housing includes a cavity sized and shaped to receive the plunger. The plunger includes a collar that when the plunger is rotated will engage a slot in the housing to deactivate the soft close functionality of the device. In an alternate embodiment, a tab slides around the exterior of the collar to engage the slot. In another alternate embodiment, the plunger includes a detent that engages a catch formed in the housing. The catch extends from a flexible arm of the housing that can be elastically deformed to deactivate and reactivate the soft-close functionality.

Claims

1. A soft-close device for a compact hinge comprising:

a housing configured to be attached to the compact hinge;

a plunger slidingly engaged with the housing and configured to abut the compact hinge;

a detent extending from the plunger;

a catch extending from the housing for engagement with the detent;

wherein upon contact with the compact hinge the plunger slides toward the housing and provides a soft-close functionality;

wherein upon engagement of the detent with the catch, the soft-close functionality is deactivated; and

,

wherein the housing further comprises;

a cavity spaced between a first sidewall and a second sidewall;

a flexible arm extending from an upper surface;

a first slot adjacent the first sidewall and the arm;

a second slot adjacent the second sidewall and the arm; and

,

an arch extending from the arm adjacent the first slot and the second slot.

2. The soft-close device of claim 1 wherein the housing further comprises:

a first side extending from an upper surface;

a second side extending from the upper surface;

a first attachment means on the first side configured to be attached to the compact hinge; and

,

a second attachment means on the second side configured to be attached to the compact hinge.

3. The soft-close device of claim 1 wherein the housing further comprises:

the flexible arm adjacent the first sidewall, the second sidewall and the cavity; and

,

whereby deformation of the flexible arm in a direction away from the cavity allows the detent to bypass the catch.

4. The soft-close device of claim 1 wherein the plunger further comprises:

a fluid filled body for slidable engagement with the housing;

a piston rod extending from the body and configured to abut the compact hinge;

a piston head attached to the piston rod for movement through the body; and

,

wherein the detent extends from the body.

5. The soft-close device of claim 1 wherein the plunger further comprises:

a body, having a first cross-section, for slidable engagement with the cavity formed in the housing, where the cavity has the first cross-section; and

,

an angled face on the body configured to abut the compact hinge.

6. The soft-close device of claim 1 wherein the plunger further comprises:

a fluid filled body for slidable engagement with the housing;

a piston rod extending from the body and configured to abut the compact hinge;

a spring, surrounding the piston rod, adjacent the body and the housing; and

,

the spring biasing the body away from the housing.

7. A method of deactivating the soft-close functionality of a soft close device having a housing slidingly engaged with a plunger, a first part defined in the housing, and a second part extending from the plunger comprising:

providing the housing configured to be attached to the compact hinge;

wherein the housing is provided to include;

a cavity spaced between a first sidewall and a second sidewall;

a flexible arm extending from an upper surface;

a first slot adjacent the first sidewall and the arm;

a second slot adjacent the second sidewall and the arm; and

,

an arch extending from the arm adjacent the first slot and the second slot

providing a plunger slidingly engaged with the housing and configured to abut the compact hinge;

providing the second part, including a detent extending from the plunger;

providing the first part, including a catch extending from the housing for engagement with the detent;

contacting the plunger with the compact hinge;

sliding the plunger toward the housing until the first part is adjacent the second part;

engaging the first part with the second part; and

,

whereby the soft-close functionality of the device is deactivated.

8. The method of claim 7 wherein the first part extends from a flexible arm formed in the housing, further comprising:

deforming the flexible arm away from the plunger; and

,

sliding the plunger away from the housing until the second part bypasses the first part.
