Abstract
A retaining sheet is used for retaining to a slat of a venetian blind. The slat has a through hole for penetration of a lifting cord. The retaining sheet includes a main body with an upper surface, a lower surface, a hole, and a slot. The hole and the slot pass through the upper and bottom surfaces of the main body and communicate with each other. The width of the slot is smaller than the width of the hole, wherein the main body is configured when the retaining sheet is retained to the slat of the venetian blind, the hole of the main body corresponds to the through hole of the slat, and the lifting cord is penetrated through the hole and inserted into the slot when pulled by an external force. This can prevent the lifting cord from being drawn out for enhancing the safety of use.

A retaining sheet for retaining to a slat of a venetian blind, the slat having a through hole for penetration of a lifting cord, the retaining sheet comprising:
- a main body having an upper surface, a lower surface opposite to the upper surface, a hole passing through the upper and lower surfaces, and a slot passing through the upper and lower surfaces and communicating with the hole and having a width smaller than a width of the hole;
- wherein the main body is configured when the retaining sheet is retained to the slat of the venetian blind, the hole of the main body corresponds to the through hole of the slat, and the lifting cord is penetrated through the hole and the through hole and inserted into the slot when pulled by an external force;
- wherein the hole has a front side edge, a rear side edge, a left side edge, and a right side edge, and the main body comprises a plurality of said slots extending away from the hole and disposed at the front and rear side edges of the hole or the left and right side edges of the hole.
A venetian blind comprising:
- a top rail;
- a bottom rail;
- a plurality of slats positioned between the top and bottom rails and each having a through hole;
- a lifting cord passing through the through holes of the slats and having two ends thereof connected to the top and bottom rails;
- and
- a retaining sheet comprising a main body having an upper surface, a lower surface opposite to the upper surface, a hole passing through the upper and lower surfaces, and a slot passing through the upper and lower surfaces and communicating with the hole and having a width smaller than a width of the hole, wherein the retaining sheet is retained to one of the slats and the hole corresponds to the through hole of the slat, and the lifting cord is penetrated through the hole and inserted into the slot when pulled by an external force;
- wherein the hole has a front side edge, a rear side edge, a left side edge, and a right side edge, and the retaining sheet comprises a plurality of said slots extending away from the hole and disposed at the front and rear side edges of the hole or the left and right side edges of the hole.
