Screen

Abstract

A screen includes: a screen body having flexibility, and onto which an image light is projected; a first support member including a screen wind-up section that supports either one of end portions orthogonal to the vertical direction of the screen body and winds up the screen body, and a base body that supports the screen wind-up section; a second support member that supports the other end portion; a column provided upright to the base body; and a retention hook that is attached to the column, and holds the second support member. The retention hook includes: a hook body that holds the second support member, and moves along the column; a latch member that is supported by the hook body, and moves between a latch position where the latch member abuts the column to latch the hook body with respect to the column and an unlatch position; a biasing member that biases the latch member toward the latch position; and a latch release member that moves the latch member to the unlatch position against a biasing force of the biasing member.

1 . A screen comprising:
 a screen body having flexibility, and onto which an image light is projected;   a first support member including a screen wind-up section that supports either one of end portions orthogonal to the vertical direction of the screen body and winds up the screen body, and a base body that supports the screen wind-up section;   a second support member that supports the other end portion;   a column provided upright to the base body; and   a retention hook that is attached to the column, and holds the second support member, wherein the retention hook includes:   a hook body that holds the second support member, and moves along the column;   a latch member that is supported by the hook body, and moves between a latch position where the latch member abuts the column to latch the hook body with respect to the column and an unlatch position;   a biasing member that biases the latch member toward the latch position; and   a latch release member that moves the latch member to the unlatch position against a biasing force of the biasing member.   
   
   
       2 . The screen according to  claim 1 , wherein the hook body includes:
 an insertion section formed with a hole for insertion of the column; and   a member storage section that has a space linked to the hole, and stores and holds the latch member, the biasing member, and the latch release member, wherein   in the member storage section, a sloped surface is formed on a side surface opposing the column inserted into the hole to be close to the column along the biasing direction of the biasing member, and is abutted by the latch member at the latch position.   
   
   
       3 . The screen according to  claim 2 , wherein
 the latch member is shaped like a cylinder, and is stored in the member storage section with an outer peripheral surface thereof opposing the column and the sloped surface.   
   
   
       4 . The screen according to  claim 1 , wherein
 the second support member supports an upper end portion of the screen body, and   the latch release member is provided on an upper side of the hook body.
