Description
Technical field
The present invention relates to a kind of also bookshelf that is used to read of clamping books, especially folding bookshelf placed.
Background technology
In daily reading, people use hand clamping books usually, or with the books horizontal to desktop.The former brings fatigue to the people easily, and the latter often makes the people bow to bend over and is unfavorable for health care, so a kind of book bookshelf of putting simply and easily of needs.At the Foldable bookshelf of the clamping books of selling usually on the market at present that are used for reading, often can not do too greatly because of the restriction that is subjected to volume after folding, can't carry bigger books when causing it to launch.
Summary of the invention
The purpose of this utility model provides the collapsible reading bookshelf of a kind of support, and the clamping books problem when reading for solving provides a solution.In this scheme, be placed into the function on the desktop after having realized will books launching at an angle, and for the reading bookshelf of selling usually on the market at present, have and to carry relatively large books and the volume after folding features of smaller.
This bookshelf mainly is made up of supporting construction behind hinge, two book block boards, two front support rods, two page clamp knees and two.In the rotating shaft with hinge is that center line is divided in the identical left and right sides two parts of structure, and each part contains a book block board, front support rod, page clamp knee, supporting construction after.
Book block board in each part respectively the respective page of the hinge cushion block by being fixedly connected on the one end and hinge be fixedly linked or an end of each book block board directly and the respective page of hinge be fixedly linked.Can make the book block board upset of the bookshelf left and right sides and open by rotating hinge.After two book block boards are opened to certain angle since an end of the connection hinge of book block board maybe this end the fixedly connected hinge page or fixedly connected hinge cushion block draw close contact mutually, and then stop hinge to be rotated further and stop the continuation of two book block boards to be overturn and make the both sides book block board stay open state.Also can bookshelf left and right sides two parts be drawn close mutually contact by the backwards rotation hinge folds up whole bookshelf.
Wherein in each part of bookshelf:
Front support rod and book block board be by linking to each other perpendicular to the rotating shaft A on the book block board plane, and make front support rod do freely to rotate on the plane of book block board around rotating shaft A;
The top of back supporting construction links to each other with front support rod by rotating shaft B, and so the direction of rotating shaft B is parallel to the book block board plane perpendicular to rotating shaft A.Back supporting construction is around rotating shaft B rotation and opening when making its lower end away from the front support rod lower end in the bookshelf process, and the part that its top and book block board side edge are touched can be provided with respective card slot, so that the book block board edge is engaged in this draw-in groove;
Back supporting construction is a back support rod, or back support rod and the back support rod bottom vertically on the screw sheel that is provided with.Under latter event, the bottom of support bar should be cylindrical and on its periphery screw thread is set, and respective threads is set and can be centered around on the periphery of back support rod at the screw sheel inwall and rotate.Make screw sheel on the longitudinal direction of the bottom of back support rod, produce displacement by rotating this screw sheel, thereby adjusted the length of back supporting construction;
The front support rod lower end links to each other with the page clamp knee by its rotating shaft C on vertically.The page clamp knee can rotate arbitrarily around rotating shaft C on the plane longitudinally perpendicular to front support rod.
Must rotate hinge earlier during use and launch both sides book block board, front support rod and back supporting construction.When launching front support rod and back supporting construction, make the respectively rotating shaft A on the book block board at its place rotation and their upper end is drawn close to the centerline direction of bookshelf of two front support rods earlier, this moment, then correspondingly launched to the direction away from the bookshelf center line bottom of supporting construction behind the bottom below the rotating shaft A and two of two front support rods, rotates to the distance that makes between the two front support rod lower ends degree greater than the distance between their upper ends.Make the B rotation around the shaft of each rear flank supporting construction simultaneously, and make supporting construction top, back draw close contact or make the draw-in groove on the back support rod block the book block board edge to this side book block board edge, thereby make the upper end of two front support rods stop to the bookshelf centerline direction draw close and the lower end of back supporting construction and this side page clamp knee stop away from.
Should make when placing bookshelf that the bottom of supporting construction contacts with desktop behind the bottom of the page clamp knee that is installed in two front support rod lower ends and two.Can rotate the page clamp knee earlier when placing books, the left and right sides two parts after again books being launched respectively are placed in the page clamp knee of the left and right sides.The upper end is more drawn close to the direction of bookshelf center line away from the bookshelf center line because the effect of bookshelf and books gravity is healed the lower end of the front support rod of A rotation around the shaft, the lower end of the back supporting construction of B rotation around the shaft is then more away from the front support rod lower end, and thereby back support rod top was blocked by the book block board edge and was made the back supporting construction stop B rotation around the shaft this moment, its result one stops away from the front support rod lower end back support rod structure lower end, the 2nd, thereby stoped front support rod to continue A rotation around the shaft the front support rod lower end is stopped away from the bookshelf center line, thereby make front support rod and book block board, back supporting construction forms stable supporting construction with certain gradient on the table.In addition, when containing turnbarrel in the supporting construction of back, can regulate the length of back supporting construction by the turnbarrel that rotates supporting construction bottom, back, thereby reach the purpose of adjusting the book block board gradient.
Pack up when folding this reading bookshelf; earlier with the back supporting construction B rotation around the shaft of both sides and their bottom is rotated on the plane of book block board of each side; this moment back supporting construction is arranged side by side with the front support rod of this side, and the upper end that no longer stops the front support rod that A around the shaft rotates to the bookshelf centerline direction draw close or the lower end of front support rod away from the bookshelf center line.At this moment with the A rotation around the shaft of the front support rod of both sides and make two front support rods and the upper end of two back supporting constructions is drawn close to the bookshelf centerline direction, the center line with bookshelf is vertical in the vertical to rotate to two front support rods.Rotate hinge again the front support rod lower end away from an end of bookshelf center line and each side of the book block board of both sides, the lower end of back supporting construction are drawn close together, promptly fold up thereby two parts of bookshelf are drawn close together.
Since remove two book block boards can be designed to width and length relatively under width less, length is than outside the long strip shape, other structure all can be designed to strip or shaft-like and collapse on two book block boards when folding, (with two book block board length is long to the area of the contact-making surface that the side that bookshelf contacts with book in the time of promptly can making the placement books in folding process forms, post upper to page clamp knee distance from bottom was wide rectangular area in the past) be reduced to the area of a book block board, and the contact-making surface that the reading bookshelf of selling usually on the market can not contact bookshelf when folding with book a side forms reduces, so adopt the bookshelf of the technical program can make volume after folding littler, also therefore this bookshelf can be easy to design to such an extent that can carry relatively large books and to be unlikely to volume after folding bigger.
Characteristics of the present invention: (1) is compared with the reading bookshelf of selling usually on the market at present for the bookshelf that can carry relatively large books after launching, and the volume after it folds is less, so carry, take care of easilier.(2) simple in structure, be suitable for popularizing.
