Rail retention system for a cordless window shade
A covering for an architectural opening includes a first rail, a second rail adjustably connected to the first rail, and a magnetic retention assembly configured to removably connect the first and second rails. The magnetic retention assembly includes a magnet coupled to one of the first rail or the second rail, and a receiver coupled to the other of the second rail or the first rail, the receiver configured to form a magnetic connection with the magnet.
1. A covering for an architectural opening comprising:
a first rail;
a second rail adjustably connected to the first rail, the second rail defining a first shoulder, a second shoulder, and a channel that is positioned between the first and second shoulders;
a light blocking flange coupled to the first rail, the light blocking flange defining a first light blocking member and a second light blocking member, the first light blocking member being spaced apart from the second light blocking member; and
a magnetic retention assembly configured to removably connect the first and second rails, the magnetic retention assembly comprising:
a magnet coupled to one of the first rail or the second rail; and
a receiver coupled to the other of the second rail or the first rail, the receiver is configured to form a magnetic connection with the magnet,
wherein in response to the magnet contacting the receiver, the first light blocking member extends into the channel, and the second light blocking member does not extend into the channel.
2. The covering of claim 1 , wherein the second rail is adjustably connected to the first rail by a first lift cord, and further comprising a third rail adjustably connected to the first rail by a second lift cord, the third rail connected to the second rail by a covering material.
3. The covering of claim 1 , further comprising a retainer coupled to one of the first rail or the second rail, the magnet received by the retainer.
4. The covering of claim 1 , wherein the covering is a top-down bottom-up shade.
5. The covering of claim 1 , wherein the receiver is positioned in the channel defined by the second rail.
6. The covering of claim 1 , wherein the receiver is configured to form the magnetic connection with the magnet in response to the magnet contacting the receiver.
7. The covering of claim 1 , wherein the first and second light blocking members are positioned on opposite sides of the magnetic retention assembly.
8. The covering of claim 1 , wherein the covering includes a first side and a second side, and in response to the magnet contacting the receiver, the first light blocking member is positioned on the first side of the magnetic retention assembly, and the second light blocking member is positioned on the second side of the magnetic retention assembly.
9. The covering of claim 8 , wherein the magnet is positioned between the first and second light blocking members.
10. The covering of claim 1 , wherein the second light blocking member includes a first portion that projects away from the first rail towards the second rail, and a second portion that angularly projects away from the first portion.
11. The covering of claim 10 , wherein the second portion is orthogonal to the first portion.
12. The covering of claim 10 , wherein in response to the magnet contacting the receiver, the second portion contacts the second shoulder that is defined by the second rail.
13. The covering of claim 1 , wherein in response to the magnet contacting the receiver, the second light blocking member contacts the second shoulder.
14. The covering of claim 13 , wherein the magnet is positioned between the first and second light blocking members.
15. A method of adjusting and retaining consecutive rails of a covering for an architectural opening comprising:
adjusting a position of a second rail in relation to a first rail, the second rail being adjustably connected to the first rail by a first lift cord;
retaining the second rail relative to the first rail by contacting a receiver carried by one of the second rail or the first rail to a magnet carried by the other of the first rail or the second rail to form a magnetic connection between the first and second rails;
forming a light blocking connection between the second rail and the first rail during the retaining step, the light blocking connection including a light blocking flange carried by the first rail, the light blocking flange including a first light blocking member positioned on a first side of the magnetic connection and a second light blocking member positioned on a second side of the magnetic connection, opposite the first side, the first light blocking member extending into a recessed channel defined by the second rail, and the second light blocking member not extending into the recessed channel; and
adjusting a position of a third rail in relation to the first rail and the second rail, the third rail being adjustably connected to the first rail by a second lift cord, wherein adjusting the position of the third rail occurs while the first and second rails maintain the magnetic connection.
16. The method of claim 15 , further comprising applying a downward force on the second rail to disengage the magnetic connection between the first and second rails.
17. The method of claim 15 , further comprising applying a downward force on the second rail to pivot the second rail with respect to the first rail to disengage the magnetic connection between the first and second rails, the pivot occurring at a pivot point defined by an interface of the second light blocking member and a shoulder that is defined by the second rail, the shoulder partially defining the recessed channel.
18. A covering for an architectural opening comprising:
a first rail;
a second rail adjustably connected to the first rail, the second rail defines a channel and at least one shoulder that borders the channel;
a light blocking flange mounted to the first rail, the light blocking flange defines a first light blocking member and a second light blocking member; and
a magnetic retention assembly configured to removably connect the first rail to the second rail, the magnetic retention assembly including:
a magnet coupled to one of the first rail or the second rail; and
a receiver coupled to the other of the second rail or the first rail,
wherein in response to the covering being positioned in a first configuration where the second rail is proximal to the first rail, the first light blocking member extends into the channel of the second rail, the second light blocking member contacts the shoulder of the second rail, and the receiver is configured to form a magnetic connection with the magnet.
19. The covering of claim 18 , wherein the at least one shoulder includes a first shoulder and a second shoulder, the first shoulder and the second shoulder bordering opposite sides of the channel, the channel is recessed relative to the first and second shoulders, and the second light blocking member contacts the second shoulder in response to the covering being positioned in the first configuration.
