## Abstract

A slide device includes a body provided at an end portion of a side of the fixed rail, and provided with a guide path, a slider coupled to the body, and selectively slidably movable along a longitudinal direction of the body during slidable movement of the transfer rail, a transfer pin coupled to the slider to be movable simultaneously at the time of movement of the slider, and movable along the guide path, and a damper provided in the body, and configured such that a rod end portion thereof is connected to the transfer pin. The slide device employs a structure in which the rod end part of the damper is detachably coupled to a sub-transfer pin without being directly coupled to the slider, and thereby can maximally prevent occurrence of a problem where the durability of the slider degrades during long-term reciprocating movement.

## Claims

### Claim 1

A slide device, comprising:
a fixed rail to be fixed to a main body;
a transfer rail slidably movable relative to the fixed rail so as to induce opening or closing movement of a drawer body;
a body provided at an end portion of a side of the fixed rail, the body having a guide path;
a slider coupled to the body, the slider being selectively slidably movable along a longitudinal direction of the body during slidable movement of the transfer rail;
a transfer pin coupled to the slider to be movable simultaneously at the time of movement of the slider, the transfer pin being movable along the guide path; and
a damper provided in the body, the damper having a rod end portion connected to the transfer pin; and
a sub-transfer pin interposed between the rod end portion of the damper and the transfer pin, the sub-transfer pin being hingedly rotatable about the transfer pin and movable simultaneously at the time of movement of the rod end portion,
wherein the rod end portion of the damper is provided with a concave neck to reduce a cross sectional area thereof;
the sub-transfer pin has a rod coupling groove at a side thereof to allow the rod end portion of the damper to be engaged therewith; and
the rod coupling groove has a neck insertion protrusion insertable into the concave neck.

### Claim 2 (depends on 1)

The slide device of claim 1, wherein the rod end portion of the damper, the transfer pin, and the sub-transfer pin are detachably coupled to each other.

### Claim 3 (depends on 1)

The slide device of claim 1, wherein the transfer pin includes:
a pin body;
a first protrusion protruding from a first surface of the pin body and being insertable through a through-hole formed in the slider;
a second protrusion protruding from a second surface of the pin body to correspond to the first protrusion and transferable along the guide path when the slider is transferred;
a third protrusion protruding from the second surface of the pin body to be spaced apart from the second protrusion and transferable along the guide path when the slider is transferred; and
a fourth protrusion protruding from the first surface of the pin body to correspond to the third protrusion;
wherein the sub-transfer pin is provided with a protrusion insertion groove to allow the fourth protrusion to be inserted thereinto; and
the transfer pin is rotatable about the protrusion insertion groove of the sub-transfer pin.

### Claim 4 (depends on 1)

The slide device of claim 1, wherein the damper has a damper protruding portion protruding at a back thereof; and
the body has a damper protruding portion-insertion groove into which the damper protruding portion of the damper is forcibly inserted.

### Claim 5 (depends on 4)

The slide device of claim 4, wherein the damper protruding portion has a cross section of an annular shape; and
the damper protruding portion-insertion groove includes an annular first insertion groove with the damper protruding portion inserted thereinto, and a straight second insertion groove communicating with the annular first insertion groove and having a width smaller than a diameter of the annular first insertion groove.
