Abstract
A head-up writing method and its auxiliary device features that two planar reflectors are combined at an angle less than 50 deg. to form a light reflector, which is then installed to relative supporter/hanger and then placed in front of writer.
Description
Technical Field
The invention relates to a head-up observation method during writing, namely head-up writing.
Background
It is known that writing is performed under observation, and a general writing observation method is overlooking observation (abbreviated as overlooking writing hereinafter), and an auxiliary device is not required, but diseases such as myopia, humpback, cervical vertebra pain and the like are easily caused by overlooking observation for a long time, and in particular to adolescent students, health is damaged, life and study are influenced, and the construction of national defense teams is lack of qualified talents.
Disclosure of Invention
In order to avoid the hidden danger of the existing overlooking writing method, the invention provides the head-up writing method, and by means of a simple device, a writer can observe the image during writing in a head-up manner when sitting at the right time.
The technical scheme adopted by the invention for solving the technical problem is as follows:
a head-up aid is composed of two planar reflectors, a light reflector at an angle less than 50 deg, and a supporter/hanger for holding the reflector in front of writer.
The invention has the advantages of keeping the proper visual range during writing in the head-up state, avoiding diseases such as myopia, humpback, cervical vertebra pain and the like caused by long-term overlooking, being beneficial to the health of teenagers and the construction of national defense teams, along with convenient implementation, simple manufacture, low cost and easy popularization.
Drawings
The invention is further illustrated by the following examples in conjunction with the drawings.
FIG. 1 is a head-up writing sight refraction diagram of the present invention.
Fig. 2 is a configuration diagram of a first embodiment of the head-up assist apparatus.
Fig. 3 is a frame diagram of the flat mirror 3 of fig. 2.
Fig. 4 is a view of a holder for the flat mirror 3 of fig. 2.
Fig. 5 is a configuration view of a second embodiment of the head-up assist device.
In the figure, 1 is a sight line path, 2 is a plane mirror combined included angle, 3 is a plane mirror, 4 is a support, 5 is a support plate, 6 is a mirror frame, 7 is a mirror frame bolt, 8 is a support bar, 9 is a mounting hole, 10 is a fastening bolt, and 11 is a nut.
Detailed Description
In fig. 1, the combined angle of the two plane mirrors of the auxiliary device is adjusted to be between 40 and 50 degrees, so that fine adjustment can be realized.
In the first embodiment of the head-up aid shown in fig. 2, a flat mirror 3 is installed in a mirror frame 6, combined according to the angle of fig. 1, and then a mirror frame bolt 7 is installed in a mounting hole 9 of a bracket 4 and a corresponding mounting hole of a support plate 5, fixed by a nut 11, and the height of the bracket and the angle of the frame are adjusted according to the requirements of a user when the head-up aid is used, so that the image written on a desktop is in a head-up range, and the head-up aid is completed.
As shown in fig. 3, a pair of mirror frames 6, the inner side of which is provided with a plane mirror 3, and the outer side of which is provided with a fixing bolt 7, can be butt-jointed and fixed with a nut 11 and a mounting hole 9 of a bracket 4 and a corresponding mounting hole of a supporting plate 5 by butt-joint and fixing, and can finely adjust the angle of the plane mirror.
In a second embodiment of the head-up aid shown in fig. 5, a support plate 5 is used to fix a frame 6 to the combination shown in fig. 1, and a support bar 8 is used to hang on a wall/cabinet in the range of head-up writing.
Claims (3)
1. A head-up aid is characterized in that: the angle between the two plane mirror surfaces of the auxiliary device is less than 50 degrees, and the auxiliary device can be finely adjusted.
