Description

[Detailed description of the invention] Purpose of the invention a. Industrial application field The invention relates to a foldable viewing platform.
Books, musical scores, maps, etc. are placed on a pedestal with the eye angle adjusted, and the pedestal and the support member that holds the pedestal at a desired angle are foldable, and placed on a desk or floor, or placed on a car seat. It is an easy-to-use viewing platform that can be hung.

b. Prior Art A conventional book stand has a structure in which a pedestal on which a book is placed is fixed at a fixed angle, and the width of the pedestal is formed to be approximately the same length as the width of the open book.

c Problems that the invention aims to solve When reading, it is said that holding a book at an angle where the line of sight intersects the surface of the book at a nearly right angle makes it easier to read and does not cause eye fatigue. Therefore, with conventional lecterns, the book surface remains at a constant angle, and since the height of the eyes varies depending on the sitting height and height of each person, the book surface and line of sight are held at almost right angles for everyone. It is impossible to cross them, and the width of the stand is almost the same length as the width of the unfolded book, so it is bulky and gets in the way when placed on a desk or the like when not in use.

Structure of the invention (a) Means for solving the problem In order to change and fix the viewing angle of the pedestal on which books, etc. are placed, in several steps, the support member that holds the pedestal is connected with two rods that can be bent freely. The upper end of the upper rod is pivotally attached to the upper part of the base column, the center part of the upper rod is moved and fixed to the base column, and the tip of the lower rod is engaged with a locking groove recessed in the frame. In addition, each rod constituting the frame-shaped pedestal is made foldable, thereby solving the above-mentioned problems.

b. Embodiments and operations The embodiments of the present invention will be described below in detail with reference to the drawings.The base column 1 is screwed with bolts 2 to the upper surface of the supplementary member 1', which is to be raised as necessary. Plant with. A pair of support members 4, 4 consisting of an upper rod 4' and a lower rod 4'' are formed by connecting the two rods in a bendable manner, and the upper end of each upper rod 4' is connected to the base column 1.
The upper rod 4' is pivotally connected to the upper side by a pin 5, and a recess 6 is provided in the center of each upper rod 4' to face each other. and locking protrusions 7, 7 that maintain and fix the desired angle.
through holes 8 through which the base pillar 1 is installed at several predetermined positions;
8', 8'', respectively, are fixed to both ends of pressing springs 9, 9, . Elongated holes 1'' are formed on both outer surfaces of the upper end of the base column 1, and at the upper end of the base rod 11, which is longer than the base column 1,
A pin 12 that is slidably inserted into the elongated hole 1'' is planted, and a recess 13 is provided in the center into which the locking pin 10 provided at the tip of the lower rod 4'' is inserted. The base of the lower frame rod 14, which is integrally formed with a shelf section 14' for receiving books, musical scores, maps, etc., is foldably pivoted to the lower end of the base rod 11, and the lower end of the support rod 15 is attached to the center. It is pivoted so that it can be raised and lowered, and a rotatable mounting bracket 16 is fixed at the tip, and a screw thread 1 is attached to the upper end.
A round rod 17 with a mark 7' carved therein is connected to the mounting fitting 16. The base end of the upper frame rod 18 is foldably screwed onto the upper part of the base rod 11, and a recess 1 is formed on the lower surface of the center.
8' is missing and the upper end of the support rod 15 is inserted, and a screw hole 18'' is carved on the lower surface of the tip and the round rod 17 is screwed into it, thereby creating a space between the upper frame rod 18 and the lower frame rod 14. A pedestal 19 is formed in which a base rod 11, a support rod 15, and a round rod 17 are arranged in parallel.In order to support the upper part of a book, etc. when the vertical length of the book is long and protrudes from the upper frame rod 18 of the pedestal 19. , the backrest member 20 is attached to the base pillar 1
It is fixed by hitting it sideways on the top surface of the. Base post 11 is base post 1
Alternatively, a leaf spring 21 that comes into elastic contact with the upper end of the base rod 11 may be fixed at one end to the backrest member 20, so that the base rod 11 is The upper end is pressed against the base column 1. As another embodiment, in order to suspend the viewing platform according to the present invention above the seat of a car, a gripping member 22 having a substantially U-shaped cross section is fixed to the back of the backrest member 20 using an elastic material, and the gripping member 22 is fixed to the back of the backrest member 20. The member 22 is locked to the upper part of the seat. Reference numeral 23 denotes a bottom plate stretched across the bottom surfaces to maintain the distance between the base rods 11, 11.

Effects of the invention According to the invention, in order to adjust the inclination of the pedestal 19 so that the line of sight intersects at a substantially right angle to the plane of the paper, the lower rod 4'' constituting the support member 4 is bent and a lock is provided at the tip thereof. When the pin 10 is engaged with the recess 13 provided in the base rod 11 constituting the pedestal 19, when the support member 4 is positioned in the vertical direction, that is, in the direction parallel to the base 1, the relationship between the pedestal 19 and the base 1 is increased. The intersection angle can be maintained at 30 degrees (first position), and the upper rod 4' of the support member 4 can be rotated counterclockwise in FIG.
If the locking protrusion 7, which is elastically inserted into the through hole 8' provided in the base column 1, is elastically supported in the recess 13 provided in the upper rod 4', the pedestal 19 can be held at 40 degrees (the 4th position). When the locking protrusion 7, which is inserted into the hole 8'', is elastically supported in the recess 13, the pedestal 19 can be held at 50 degrees (first position), and the angle of the line of sight relative to the paper surface can be set at a nearly right angle, depending on the height of the reader. It is easy to use and can therefore prevent eye fatigue.Furthermore, if the base column 1 itself is raised using the additional member 1', it is convenient for tall people to use it.Furthermore, the grip member 22 can be attached to the seat of a car. When suspended from the top, road maps and the like can be placed on the pedestal 19, making it easy to judge road conditions.Furthermore, if the base 1 itself is made high enough to reach the line of sight of the person, musical scores, etc. placed on the pedestal 19 can be placed on the pedestal 19. The viewing platform itself is compact, making it easy to carry and easy to use by installing it at a desired location.

Therefore, after use or storage, the support member 4 is attached to the base column 1.
The round rod 17 connecting the lower frame rod 14 and the upper frame rod 18 constituting the frame 19 is unscrewed, and the round rod 17 is lowered into the receiving shelf part 14', and the support rod 15 Similarly, lower it onto the shelf part 14',
Raise the lower frame rod 14 in the direction along the base rod 11,
By hanging the upper frame rod 18 in the direction along the base rod 11, the viewing platform itself can be folded compactly.

As described above, the present invention is an excellent and useful device that has a robust structure, is easy to manufacture, and is easy to handle.
