Abstract
A self-supporting portable projection screen consists of self-supporting steel bands, screen materials and screen edge materials. The self-supporting portable projection screen is characterized in that: the screen edges of the projection screen are provided with the self-supporting steel bands which take curvy shape in original state, the self-supporting steel bands which are straightened and stretched take the shape of vertical bars with grooves, the self-supporting steel bands of the vertical bars have very strong elastic bearing force, and the self-supporting steel bands which are fixed in parallel or in a cross way can support the screen very evenly. The self-supporting steel bands are used for the projection screen, which solves the portable supporting problem of the projection screen and the microminiature package problem of the portable screen, and being capable of meeting convenient carrying needs of mini-projector users. With development and popularization of projectors, the self-supporting portable projection screen has very good popularization and application prospects.
Description
Technical field
The present invention relates to a kind of projection screen, be specifically related to a kind of self-supporting portable projection screen.
Background technology
Along with the continuous progress of digital projection technique, the volume of projector is more and more littler, and the scope of flow applications more and more widely.Current in the personal consumption field, various portable translucent machines such as the desktop minitype projection machine that occurs on the market, pocket projector and mobile phone projectors, caused consumers in general's great interest, they wish to use these portable translucent machines with oneself, for commercial activity or entertainment bring more convenience.But the use of projector be unable to do without and the cooperating of projection screen, if minitype projection machine does not have suitable supporting projection screen, its projection project effect will be had a greatly reduced quality.Yet, although existing projection screen has had a lot of portable new products, all not having subminiaturized portable screen to support so far and set up structure, the volume of existing portable screen is relatively still very big, can't carry use more easily.Therefore, popularizing of minitype projection machine needs a kind of can either the support at any time to set up at present, and the small and exquisite especially again portable translucent screen of packaging volume comes supporting, has only this screen could satisfy user's the demand that is convenient for carrying.
Summary of the invention
In order to satisfy the demand that the minitype projection machine user is convenient for carrying projection screen, the invention provides new departure of a kind of self-supporting portable projection screen, be characterized in: the curtain at projection screen has installed and fixed a kind of self-supporting steel bands on the limit, this self-supporting steel bands have regain the volume that circumnutates little, launch to form the high characteristic of recess supports intensity.On projection screen, utilize this self-supporting steel bands, not only solved the portable support problem of projection screen, and solved the microminiature packaging Problems of this screen, can satisfy the demand that the minitype projection machine user is convenient for carrying.
The present invention addresses the above problem the scheme that is adopted: a kind of self-supporting portable projection screen includes self-supporting steel bands, screen material and curtain sapwood material.Be characterized in: be connected with an act sapwood material on the surrounding of screen material, four jiaos of curtain sapwood material are provided with the perforation that connects self-supporting steel bands; Self-supporting steel bands is very frivolous, and width is 2～10cm, is provided with clasp nail at its two ends; Self-supporting steel bands is a circumnutate-shaped in virgin state, forms the vertical bar shape with groove after the stretching stretching, extension, and the self-supporting steel bands that forms the vertical bar shape has very strong elastic anchorage force; With the clasp nail at self-supporting steel bands two ends, be buckled in the perforation on four angles of screen, self-supporting steel bands parallel or that intersect just can very entirely support screen; Dismantle screen if desired, as long as flatten the groove on the self-supporting steel bands vertical bar shape termination gently, self-supporting steel bands will be become the circumnutate-shaped of virgin state by vertical bar shape automatic winding, and screen comes off immediately; At this moment the volume of self-supporting steel bands is just very little, puts together with collapsible screen, has realized the microminiature packing, is easy to carry especially.According to user's needs, the screen material that is adopted can be a kind of glass microballoon material, also can be a kind of plastic material, can also be a kind of fibers material; Make rule in order to meet screen, curtain sapwood material is a kind of textile of black.
Advantage of the present invention is: utilize the light supporting construction of a kind of self-supporting steel bands as screen, replaced the heavy stilt in traditional projection screen, realized the microminiature packing of projection screen, satisfied minitype projection machine user's the demand of carrying.Under the situation of minitype projection machine fast development, this self-supporting portable projection screen has very good popularizing application prospect.

Embodiment
The specific embodiment of the present invention is: a kind of self-supporting portable projection screen includes self-supporting steel bands 1, screen material 2 and curtain sapwood material 3.Be characterized in: be connected with an act sapwood material 3 on the surrounding of screen material 2, four jiaos of curtain sapwood material 3 are provided with the perforation 4 that connects self-supporting steel bands 1; Self-supporting steel bands 1 is very frivolous, and width is 4cm, is provided with clasp nail 5 at its two ends; Self-supporting steel bands 1 is a circumnutate-shaped 6 in virgin state, and the stretching back of stretching forms the vertical bar shape 8 with groove 7, and the self-supporting steel bands 1 that forms vertical bar shape 8 has very strong elastic anchorage force; With the clasp nail 5 at self-supporting steel bands 1 two ends, be buckled in 4 li of perforation on four angles of screen, self-supporting steel bands 1 parallel or that intersect just can entirely support the screen ten minutes; Dismantle screen if desired, as long as flatten the groove 7 on self-supporting steel bands 1 vertical bar shape 8 terminations gently, self-supporting steel bands 1 will be become the circumnutate-shaped 6 of virgin state by vertical bar shape 8 automatic windings, and screen comes off immediately; At this moment the volume of self-supporting steel bands 1 is just very little, puts together with collapsible screen, has realized the microminiature packing, is easy to carry especially.According to user's needs, the screen material 2 that is adopted can be a kind of glass microballoon material, also can be a kind of plastic material, can also be a kind of fibers material; Make rule in order to meet screen, curtain sapwood material 3 is textiles of a kind of black.
