Description
Technical field
It is a kind of to look squarely tool of reading and writing the present invention relates to a kind of schooling apparatus.
Background technique
Student needs often to bend over the desk for a long time to write and read.In order to meet writing on table and reading and trick association
It adjusts, people must not have to the posture bowed, eye gaze desktop.And it will lead to cervical vertebra, back using the posture bowed for a long time
Acid is swollen and tired, brings cervical spondylosis and other health hazards.
Having a kind of scheme at present is that desktop is tilted upward, it is intended to reduce the angle bowed.But if desktop inclination is smaller,
Still the posture bowed is kept；If gradient is larger, although can bow to avoid wide-angle, arm lacks upwards when writing
Strength rely on, user is tired out soon.This does not well solve problem.
Summary of the invention
It helps people to get rid of the constraint for generalling use heads-down posture in writing and reading, book can be carried out with the posture of head-up
It writes and reads, urgent need is a kind of to look squarely tool of reading and writing.
In order to achieve the above object, it reads and writes tool the technical scheme is that providing a kind of head-up, it can be with desk
It is used cooperatively, feature composition is: including recessed cylindrical mirror, supporting bindiny mechanism, fixing seat, the support bindiny mechanism
One end is connected to the recessed cylindrical mirror, and the recessed cylindrical mirror is supported in the top of desk, described in other end connection
Fixing seat, the weight of the fixing seat carrying support bindiny mechanism and the recessed cylindrical mirror, and described in holding
Head-up is read and write the stabilization of tool, and the recessed cylindrical mirror is in horizontal attitude, and the arc curve mirror of recessed cylindrical mirror from bottom to top
The corresponding horizontal direction that is oriented of each point is to vertical downward direction.
In vertical direction or including at least a set of hinge and support plate, the hinge connects for the support bindiny mechanism
The support plate is connect, or including a set of support plate made of curvature memory material, or including at least a set of hinge, is used for
The pitch angle of recessed cylindrical mirror adjusts and recessed cylindrical mirror is supported to reach suitable height, preferably, the support plate
Including coulisse, expansion plate and adjust lock, the lower end of the expansion plate be inserted into closely be slidably matched mutually it is described
In coulisse, the expansion plate is arranged in for the adjusting lock and the coulisse is slidably matched in section, with convenient
Recessed cylindrical mirror adjusts height, to adapt to the mutual cooperation of user and desk.
The optical distance U of the recessed cylindrical mirror focal length f and recessed cylindrical mirror to the writing picture and text paid close attention to meets relational expression:
U/2 ≤f < U
The fixing seat or with the table side fixing clamp that can be fixedly secured with desk, or read and write work with head-up is extended to
Supporting surface except the center of gravity of tool, to keep the head-up to read and write the stabilization of tool.
The head-up tool of reading and writing is fixed or is placed on desk, the height of recessed cylindrical mirror is adjusted, adjusts recessed cylinder
The mirror surface center of mirror reaches the height of user's eyes head-up, adjusts the angle of the mirror surface direction of recessed cylindrical mirror, makes to watch attentively
Desk on the writing picture and text that lie low can reach the eyes of user by the light reflection of mirror surface, it is identical to form upright size
Or similar picture and text, the constraint in writing and reading using heads-down posture is got rid of, and avoid thus caused cervical vertebra, back
Acid is swollen and tired.

Specific embodiment
It elaborates below with reference to specific embodiment to the present invention, the present embodiment is given in detail premised on the present invention
Embodiment and specific operating process.
It is a kind of to look squarely tool of reading and writing as shown in Fig. 1,2 and 3, it is fixed on desk 1, comprising: recessed cylindrical mirror 2, support
Bindiny mechanism 3, fixing seat 4, one end of the support bindiny mechanism 3 are connected to the recessed cylindrical mirror 2, and the other end is connected to
The fixing seat 4, and the head-up is kept to read and write the stabilization of tool.The recessed cylindrical mirror 2 includes 22 He of mirror holder
Mirror surface 21, the top of desk 1 is supported horizontally in prone position, and the mirror surface 21 is close to the mirror holder 22.
Preferably, the support bindiny mechanism 3 includes two torsional moment hinges (annotation) 31 and support plate 32, described
One end of support bindiny mechanism 3 mirror holder 22 of the recessed cylindrical mirror 2 is connected by one of torsional moment hinge 31, it is described
The other end of support bindiny mechanism 3 fixing seat 4 is connected by another torsional moment hinge 33 therein.The support
Plate 32 includes coulisse 322, expansion plate 321 and adjusting lock 323, and the lower end of the expansion plate 321 is inserted into close mutually
In the coulisse 322 being slidably matched, the expansion plate 321 and the cunning is arranged in the adjusting lock 323
Frid 322 is slidably matched in section.
Preferably, which is fixedly mounted on 1 edge of desk, 4 institute of fixing seat
The fixing 41 of band holds the insertion of desk edge, is tightened with the fixing bolt 42 of the fixing seat 4, the fixing seat 4 is just
It is fixed on desk 1.
The collapsing length that the adjustment expansion plate 321 and the coulisse 322 are slidably matched, to adjust the branch
The length for supportting the support plate 32 of bindiny mechanism 3 makes 21 centre bit of mirror surface of recessed cylindrical mirror 2 so as to adjust the height of recessed cylindrical mirror 2
The height for reaching the head-up of user's eyes 53 is set, adjusting lock 323 is tightened, to lock the height of recessed cylindrical mirror 2.
The connection angle of the adjustment torsional moment hinge 31, the pitch angle of 21 direction of recessed cylindrical mirror 2 and mirror surface is therewith
Change, until the writing picture and text on desk 1 are mapped to the light 51 of the mirror surface 21 of recessed cylindrical mirror 2 after the reflection of mirror surface 21, instead
Until penetrating the eyes 53 that light 52 can reach user, 31 self-sustaining of the torsional moment hinge connection angle.
The connection angle of the adjustment torsional moment hinge 33, recessed cylindrical mirror 2 leave reading writing picture and text and user away from
From changing correspondingly, until suitable distance, 33 self-sustaining of the torsional moment hinge connection angle.
Three above set-up procedure is repeated, to optimize and revise.User looks squarely the mirror surface 21 of recessed cylindrical mirror 2, can see clearly
The upright graph text information same or similar with picture and text size is write on desk.
In this way, user can look squarely the graph text information paid close attention on the desk of the inner reflection of recessed cylindrical mirror 2 in front on one side,
It writes on the table on one side, hand eye coordination.The object of the invention is reached.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
Annotation: so-called torsional moment hinge refers to that the connection angle of hinge can change when being greater than under presetting torque effect
Become, when the torque of effect is less than presetting torque, connection angle remains unchanged and continues a kind of hinge maintained.
