The present invention relates to a reading table for supporting a book or reference document in the case of reading or writing a document by a computer. In particular, the articulation structure can be firmly held and a book can be held. The present invention relates to a reading table having a multi-joint that allows a user to face the book or reference document in any position of the support plate supporting the book.

Various products have been developed as a reading table for reading or writing documents using a computer, and among them, the lower part of the leg is detachably fixed to the corner of the desk. The one disclosed by reference is representative.

The reading table of the Korean Utility Model Publication No. 92-7146 is a pedestal, each of which has a paper fixing arm coupled to both sides of a support plate formed at a lower end thereof so as to be able to swing up and down, and an inclined place for supporting the pedestal so as to be able to lift the pedestal. Supporting the arm and the desk, the first rotating body for rotatably supporting the inclined support is rotatably coupled to one end and the second rotating body is rotatably coupled to the other end, and supporting the arm on a desk. It consists of a fixing means consisting of a conventional bolt and nut coupled to the second rotating body.

In order to view a book by a conventional reading table as described above, first, while holding the book open and resting on the stand, turning both paper fixing arms up to grasp both roots of the book (the bottom of the book when the book is opened). Do it. In this way, the book can be viewed while being supported on the support plate in the inclined state. In this state, when the left and right rotation states of the pedestal do not match, the pedestal can be left and right rotated by the rotation of the arm by the first and second rotating bodies, so that the left and right rotation angles of the pedestal can be adjusted. When the height of the pedestal does not match, the height of the pedestal can be adjusted to the eye level by lifting the pedestal along the inclined support.

However, in the conventional reading table as described above, there are the following problems.

First, since the pedestal and the arm are pivoted only in the left and right directions and the pedestal is lifted along the inclined support, there is a limitation in properly matching the height and the eye height of the pedestal. That is, since it is a structure in which the pedestal cannot be rotated up and down, for example, when the lowest position of the pedestal is higher than the eye level, or when the highest position of the pedestal is considerably lower than the eye level, the pedestal is placed on the pedestal. There is a problem that the eyes are easily tired because the letters are not clearly visible because the old books cannot be viewed in front.

Second, as described above, the pedestal can not be rotated up and down, and the top of the pedestal is always kept inclined backward by the inclined support, for example, there is a problem that is impossible to see the book in the lying down state.

Third, when lifting and lowering the pedestal along the inclined support, loosen the thumbscrews fixed on the inclined support and raise and lower the inclined support to an appropriate position, and then tighten the bow bolt again to fix the pedestal. Not only did it take a lot, but it was also quite uncomfortable.

Fourth, both paper fixing arms do not grasp the folds (books), or judges (版 心: in the case of old books, they do not grasp the folded part in the middle of the book, that is, the vertical goal in the middle). Because the gripping, the parts located on both sides of the judgment core are protruded forward and obscure the letters, so the letters of the parts are not easily seen, especially in the case of small books, the bookcase can be easily removed from the holding state by the supporting arm. Even holding a book was a difficult problem.

The present invention has been devised in view of the above-mentioned conventional problems, and adopts a multi-joint structure so that the support plate for supporting the book can be positioned over all directions so that the book or reference document supported on the support plate can always be seen from the front. In addition, the object of the present invention is to provide a reading stand that can firmly maintain the tilt adjustment state of the support plate.

Another object of the present invention is to ensure that the grip is firmly gripped so that the portions located on both sides of the book's judgement do not protrude forward and obscure the letters.

An additional object of the present invention is to facilitate the support of reference documents.

Accordingly, the present invention, the support plate protruding forward and formed at the bottom; A first arm having one end connected to a center of a rear surface of the support plate so as to be selectively pivoted up and down; A first fixing device for selectively controlling a fixing state between the first and second coupling rings; A second arm having one end connected to the other end of the first arm in a rotatable manner; An elbow arm coupled to the other end of the second arm so that the end of the horizontal rod is rotatable left and right; And a second hollow having a fixing portion at a lower end thereof to be coupled to an edge of the plate, and having a hollow into which the vertical rod of the elbow arm is inserted, and to support the vertical rod inserted into the hollow so as to be swivelable and selectively liftable. By including a support with a locking device, the first object can be achieved.

That is, in the present invention, a first coupling ring having a first linear bevel gear portion integrally formed on one side is formed at the center of the rear surface of the support plate, and at one end of the first arm, the first bevel gear is disengaged with the first linear bevel gear. A second engagement ring having a second linear bevel gear portion meshed with the first linear bevel gear portion is formed to be able to rotate up and down, and wherein the first fixing device selectively restricts vertical movement between the support plate and the first arm. And a cam handle having a first hinge pin having a stopper attached to one end thereof and a cam portion coupled to the other end of the first hinge pin so as to penetrate the holes of the first coupling ring and the second coupling ring. The first and second straight bevel gear parts may be selectively engaged or released according to vertical movement of the cam handle. Therefore, in the state in which the engagement is released, since the support plate and the first arm can be vertically rotated, the desired inclination angle of the support plate can be easily adjusted.

In addition, the upper and lower coupling rings are formed side by side at the other end of the first arm, and three coupling rings which are coupled to the upper and lower coupling rings of the first arm so as to rotate left and right are sequentially formed at one end of the second arm, The first arm and the second arm may be coupled to each other so as to rotate left and right, and the other end of the second arm is formed with the upper and lower coupling rings the same as the coupling ring formed at one end of the first arm, the horizontal rod of the elbow arm At the end, three coupling rings identical to the three coupling rings formed at one end of the second arm are formed, whereby the second arm and the elbow arm can be coupled to each other in a left-right rotational manner.

In addition, the second fixing device of the support is a clamping piece inserted into the hole formed in one side of the upper end of the support so as to be movable back and forth, and the vertical rod of the elbow arm inserted into the hollow of the support by the forward and backward movement of the clamping piece according to the left and right rotation Cam handles are coupled to one side of the upper end of the support so as to selectively sandwich the elbow arm, which can support the elbow arm in a left-right rotational state with respect to the support, and selectively elevate the elbow arm according to the left-right rotation of the cam handle. I can support it in a state that I can do it.

In addition, in the present invention, the first fixing clip is coupled to the center of the support flange by a torsion spring so as to be able to grip the lower end of the core of the book supported by the support plate is further added, the second The purpose can be achieved.

In addition, in the present invention, it is possible to support the second fixed clip and the lower end of the reference document elastically coupled to the upper end of the support plate by a torsion spring so as to easily grip the upper end of the reference document. The additional object can be achieved by further adding a hinge consisting of a bracket which is lifted and detachably coupled along a left end or a right end of the support plate, and a horizontal cross that one end is pivotally coupled to the bracket.

Other features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

1 is a perspective view showing another reading table according to the present invention, FIG. 2 is a front view, FIG. 3 is a plan view, FIG. 4 is a left side view, FIG. 5 is a right side view, and FIG. 6 is a rear view.

As in the drawings, reference numeral 1 denotes a support plate 1 for supporting the book 10 (see FIG. 12), and reference numeral 2 is selectively pivotally coupled to the center of the rear surface of the support plate 1. The 1st arm for adjusting the inclination of the said support plate 1 is shown. Further, reference numeral 3 denotes a first fixing device for selectively coupling the support plate 1 and the first arm 2 to be rotatable vertically.

The support plate 11 is formed at the lower end of the support plate 1 to protrude forward, so that the support plate 1 has a c-shape with an upper portion extending upward when looking at the support plate 1 from the left side. In addition, as shown in FIG. 8, the first coupling ring 13 having the first linear bevel gear portion 15 formed on one side (here right side) is integrally formed at the center of the rear surface of the support plate 1. It protrudes. That is, the hollow 17 of the first coupling ring 13 is formed in the left and right directions.

Next, as shown in FIGS. 8 to 11, the first arm 2 faces the first straight bevel gear 15 so as to be detachably engaged with the first straight bevel gear portion 15. The second coupling ring 23 having the second linear bevel gear portion 25 is integrally formed at one end on one side thereof (the left side here), and the upper and lower coupling rings 21 and 22 are formed side by side at the other end. It is. In addition, the hollow 27 of the second coupling ring 23 of the first arm 2 is in communication with each other by being in line with the hollow 17 of the first coupling ring 13, the first and second When the straight bevel gears 15 and 25 are engaged, the support plate 1 and the first arm 2 cannot be rotated up and down mutually, and in the state where the engagement is released, the support plate 1 and The 1st arm 2 is in the state which can be mutually rotated up and down. Therefore, in the disengaged state, the inclination angle of the support plate 1 can be adjusted to an arbitrary angle.

In addition, the first fixing device 3 is to fix the inclination and the adjusted inclination angle of the support plate 1 by selectively controlling the engagement and the release of the teeth as described above, the first, second coupling ring 13 The first and second stoppers 32 are formed at one end and are installed through the hollows 17 and 27 of the first and second coupling rings 13 and 23 so as to couple the 23 to each other so as to pivot and move left and right. The hinge pin 31 and the first and second linear bevel gears 15 and 25 are engaged with each other in a vertical rotation so as to be pivotally coupled to the other end of the first hinge pin 31 so as to engage or disengage each other. It consists of a cam handle 33 having both cam portions 35 and 36.

Both cam portions 35 and 36 are formed at the tip of both branches of the yoke 34 in turn, so that the cam handle 33 is formed between the first hinge pins 31 between the two cam portions 35 and 36. Both cams 35 and 36 and the first hinge pin 31 may be coupled up and down by the pin 37 in a state where the other end is positioned.

That is, when the cam handle 33 is rotated upward, both cam portions 35 and 36 rotate downward to release the state in which the second coupling ring 23 is pushed toward the first coupling ring 13 to thereby release the first, The engagement between the two linear bevel gear parts 15 and 25 is released, and in this state, the first and second linear bevel gear parts 15 and 25 rotate each other, that is, the first and second coupling rings 13 ( Since the mutual rotation of 23 is possible, the inclination angle of the support plate 1 can be arbitrarily adjusted by pivoting the support plate 1 or the first arm 2 up and down.

In addition, when the cam handle 33 is rotated downward again while the inclination angle is adjusted as described above, both cam portions 35 and 36 rotate upward again to form the second coupling ring 23 as the first coupling ring ( 13), the first and second linear bevel gear parts 15 and 25 mesh with each other. Therefore, the tilt adjustment state of the support plate 1 can be firmly fixed.

Meanwhile, the second arm 4 is connected to the upper and lower coupling rings 21 and 22 of the first arm 2 so as to be rotatable, and at one end, the upper and lower coupling rings 21 of the first arm 2 are connected. ) 22 and three coupling rings (41, 42, 43) that are coupled to the left and right pivotal order from the top to the bottom, and the other end of the upper and lower coupling ring formed on one end of the first arm (2) Coupling rings 45 and 46 which are the same as those of (21) and (22) are formed.

The three engaging rings 41, 42, 43 of the second arm 4 are coupled to the upper and lower coupling rings of the first arm 2 by a second hinge pin 47 having a stopper 49 formed at one end thereof. By being coupled to (21) and (22) so that left and right rotation is possible, the 1st arm 2 and the 2nd arm 4 become mutually left and right rotatable with the 2nd hinge pin 47 as an axis.

In addition, the elbow arm 5 coupled to the second arm 4 so as to rotate left and right, the left and right engagement rings 45 and 46 of the second arm 4 can rotate left and right at the end of the horizontal bar 51. Three coupling rings (52, 53, 54) identical to the three coupling rings (41) (42) (43) formed at one end of the second arm (4) are formed so that the three couplings Rings 52, 53 and 54 are coupled to the upper and lower coupling rings 45 and 46 of the second arm 4 by a third hinge pin 57 having the same shape as the second hinge pin 47. By being rotatably coupled, the second arm 4 and the elbow arm 5 can rotate left and right with the third hinge pin 57 as an axis.

In addition, the support 6 is for supporting the vertical rod 55 of the elbow arm 5 so as to be swivelable and selectively liftable. The support 6 has a hollow 62 and a hollow 62 on one side of the outer peripheral surface of the upper end. A support rod 61 having a hole 63 communicating therewith, a fixing portion 65 provided at a lower end of the support rod 61 so as to be fixed to a corner portion of a plate such as a desk, and an elbow arm inserted into the support rod 61. And a second fixing device 70 for supporting the vertical bar 55 of (5) to be swivelable and selectively liftable.

The fixing part 64 is installed to be elevated by left and right pivoting through the channel 66 installed at the lower end of the supporting rod 61 and the lower flange 67 of the channel 66 and is sandwiched at the upper end. It consists of a screw rod handle 68 provided with a plate 69.

In addition, the second fixing device 70 of the support 6 is a clamping piece 71 inserted into the square hole 63 formed on one side of the upper end of the supporting rod 61 so as to be movable back and forth, and the clamping piece according to left and right pivoting. A cam coupled to one side of the upper end of the support 6 to selectively pinch the outer circumferential surface of the vertical rod 55 of the elbow arm 5 inserted into the hollow 62 of the support 6 by moving forward and backward of the 71. The handle 72 allows the elbow arm 5 to be rotatable left and right with respect to the support 6 and to selectively lift the elbow arm 5 according to the left and right rotation of the cam handle 72. Can be placed in a state.

The clamping piece 71 has a substantially rectangular structure corresponding to the rectangular hole 63, and the inner surface preferably forms an arc surface having the same radius as the inner circumferential surface of the support bar 61. This supports the vertical rod 55 in a state in which left and right pivoting is possible, but the lifting and lowering is impossible when the clamping piece 71 is in close contact with the outer circumferential surface of the vertical rod 55 of the elbow arm 5 inserted into the supporting rod 61. To do this. In addition, the cam handle 72 has cam portions 73 and 74 formed on both sides thereof without the yoke 34 as in the cam handle 33 of the first fixing device 3. The left and right pivots of the vertical rods 55 of the elbow arm 5 are coupled to the engaging portion 64 formed around them by the pin 75 so as to rotate left and right. The lift is selectively limited.

That is, when the cam handle 72 is rotated to the left about the pin 75, both cam portions 73 and 74 which have pushed the outer surface of the sandwich piece 71 rotate to the right, and the sandwich piece 71 supports the support rod 61. By being in a state capable of retracting in the radial outward direction, the vertical rod 55 of the elbow arm 5 is liftable, and when the cam handle 72 is rotated to the right, both cam portions 73 and 74 are rotated. ) Is rotated to the left side again and the vertical rod 55 is sandwiched between the inner circumferential surface of the support rod 61 and the inner surface of the pinch piece 71 by pushing the clamping piece 71 toward the supporting rod 61. ) Is able to rotate left and right, but not ascend or descend. That is, in this state, since the inner circumferential surface of the support bar 61 and the inner surface of the sandwich piece 71 form an arc surface, the vertical rod 55 can only rotate left and right.

Meanwhile, as shown in FIGS. 1 and 7, the first fixing clip 7 has an angular cross section, and is provided by the torsion spring 78 at the center of the support flange 11 of the support plate 1. Elastically coupled up and down rotatable. Specifically, the first flange 76 of the first fixing clip 7 is placed on the front surface of the support flange 11 and the second flange 77 of the first fixing clip 7 is a support flange ( A shaft portion (not shown), which is disposed on the upper surface of 11 and formed on both rear surfaces of the first flange 76, is formed to face both sides of the bottom surface of the support flange 11 in a corresponding direction. G) is designed to be rotated. In addition, the stop portion of the torsion spring (78) wound on both shafts is supported on the bottom of the second flange 77, and both ends of the torsion spring (78) support the bottom of the support flange (11). The fixed clip 7 is coupled to the support flange 11 to be able to rotate up and down elastically.

Accordingly, when the book 10 is placed on the support plate 1 in the state where the second flange 77 of the first fixing clip 7 is turned upward, and then the first fixing clip 7 is placed, the torsion spring 78 Since the second flange 77 pivots toward the support plate 1 by the elastic force, the lower end of the plate core of the book 10, that is, the lower end of the pear is elastically pushed toward the support plate 1, so that the book 10 is supported by the support plate 1. Can be firmly supported. Thereby, the parts located on both sides of the core of the book 10 can be gripped so as not to protrude forward.

In addition, in the present invention, when the reference document is to be supported, a second fixing clip 8 that is elastically coupled to the upper and lower pivots by the torsion spring 83 is further added to the upper end of the support plate 1, In addition, a hinge made of a lifting bracket 91 which is lifted and detachably coupled along a left end or a lower end of the support plate 1 and a horizontal arm 92 which is coupled to one end of the lifting bracket 91 so as to rotate left and right. 9) is also added to facilitate the support of reference documents.

The second fixing clip 8 has a substantially channel-shaped cross-sectional structure, and is arranged to cover the top center portion of the support plate 1 from top to bottom, as in the assembled state of the first fixing clip 7 described above. , By the torsion spring 83 is elastically coupled back and forth. Therefore, when the rear flange portion 82 of the second fixing clip 8 is pressed, the front flange portion 81 of the second fixing clip 8 is rotated upwards so that the upper end and the front flange portion 81 of the support plate 1 are rotated. When the rear flange portion 82 is placed while the upper end portion of the reference document is inserted between the gaps, the front flange portion 81 again moves toward the support plate 1 by the elastic force of the torsion spring 83. By flexibly rotating, the upper end of the reference document can be gripped.

In addition, the lifting bracket 91 of the hinge 9 is lifted along the rail 19 of a portion formed at the left or right side of the rail 19 formed along the front edge of the support plate 1. It is coupled to the left end or the right end of the cross-section 92 is coupled to the elevating bracket 91 is located in the transverse direction on the front surface of the support plate 1 so that it can be turned left and right around the elevating bracket (91). By doing so, while supporting the reference document on the support plate 1 by the second fixing clip (8) in accordance with the lifting and lowering of the lifting bracket 91 and the left and right turning of the cross (92) the reference document so as not to fly You can grasp the proper position of.

Next, the operation of the reading table according to the present invention configured as described above will be described.

First, as shown in FIG. 10, the cam handle 33 is upward to release the first and second linear bevel gear parts 15 and 25 from being engaged with each other to adjust the inclination angle of the support plate 1. When rotated, the two cam portions 35 and 36 move the second coupling ring 23 by downward rotation of both cam portions 35 and 36 of the cam handle 33 constituting the first fixing device 3. The state of pushing toward the first coupling ring 13 is released, so that the second coupling ring 23 slightly moves to the right, thereby releasing engagement between the first and second linear bevel gear parts 15 and 25. . Therefore, the state in which the engagement is released is a state in which the first and second coupling rings 13 and 23 can be rotated up and down, so that the support plate 1 or the first arm 2 is rotated up and down to incline the angle of the support plate 1. Adjust it properly.

After the inclination angle adjustment is finished, as shown in FIG. 5, when the cam handles 33 are rotated downward again to raise both the cam portions 35 and 36, the cam portions 35 and 36 are removed. By pushing the second coupling ring 23 toward the first coupling ring 13, the first and second linear bevel gear parts 15 and 25 are engaged with each other, so that the first and second coupling rings 13 and 23 rotate up and down. It becomes impossible. Therefore, the inclination adjustment state of the support plate 1 can be firmly fixed.

In adjusting the inclination angle of the support plate 1 as described above, since the support plate 1 can be rotated up and down nearly 360 ° with respect to the first arm 2, the inclination angle can be adjusted in a wide range.

When the inclination adjustment is completed as described above, next to adjust the left and right positions of the support plate (1). That is, when holding the support plate 1 and rotating it left and right, as shown by the arrow in FIG. 3, the left and right rotations of the 1st engagement ring 13 and the 1st arm 2 of the support plate 1, and 1st Left and right rotation of the arm (2) and the second arm (4), left and right rotation of the second arm (4) and elbow arm (5), and left and right rotation of the support (6) of the elbow arm (5), ie Since the left and right rotation by the multiple joints are made, respectively, the support plate 1 can be placed in a position where the support plate 6 can always be seen in the front, no matter where the support plate 1 is placed.

If the eye height does not match the height of the support plate 1, the cam handle 72 of the second fixing device 70 is rotated to raise and lower the vertical rod 55 of the elbow arm 5 to fit the eye level. The cam handle 72 may be rotated in the opposite direction to fix the elbow arm 5 in a state in which the elbow arm 5 cannot be elevated. Even though the eye height and the height of the support plate 1 are adjusted in this way, when the eye height is out of the lifting distance of the vertical rod 55 of the elbow arm 5, the support plate 1 is rotated up and down as described above. What is necessary is just to adjust so that the support plate 1 may be frontally seen. In particular, if you want to see the book 10 lying down, the book 10 is to grip the upper end of the core of the book 10 by the second fixing clip 8 so as not to fall down.

Next, in a state in which the second fixing portion 77 is rotated upward by rotating the first fixing clip 7, the book 10 is placed on the support plate 1, and then the first fixing clip 7 is released. The second flange portion 77 is elastically rotated back toward the support plate 1 by the elastic force of the spring 83 so that the plate center of the book 10, that is, the lower end of the pear, is shown in FIG. Since it is elastically pushed toward 1), the book 10 can be firmly gripped. Therefore, the parts located at both sides of the open core of the open book 10 can be prevented from protruding forward.

Next, in the case of supporting the reference document, when the rear flange portion 82 of the second fixing clip 8 is pressed, the front flange 81 of the second fixing clip 8 rotates upward to support the support plate 1. There is a gap between the upper end of the and the front flange portion 81. When the rear flange portion 82 is placed in the state in which the upper end portion of the reference document is sandwiched between the gaps, the front flange portion 81 is elastically rotated toward the support plate 1 again by the elastic force of the torsion spring 83. Therefore, since the front flange 81 pushes the upper end of the reference document toward the support plate 1, the upper end of the reference document can be firmly gripped.

Thus, when there is a risk that the lower end of the reference document may be blown away by, for example, a wind by a fan or the like while the reference document is held, the cross 92 is left on the lifting bracket 91 of the hinge 9. After turning to the horizontal plate 92 in a state where the lower end of the reference document is positioned between the support plate 1 and the cross ruler 92, the cross ruler 92 pivots toward the support plate 1 by reference to the reference document. Since the lower part of the gripper can be avoided from flying the lower part of the reference document. In addition, since the lifting bracket 91 of the hinge 9 can be moved up and down along the rails located on the left and right sides of the support plate 1, the grip position of the hinge 9 with respect to the reference document along the length of the reference document. Can be changed as appropriate.

As described above, according to the reading table according to the present invention, since the inclination angle of the support plate 1 can be adjusted in a wide range by supporting the support plate 1 so that it can be rotated not only in the left and right directions but also in the vertical direction, the support plate 1 is Wherever you are, you can view the book 10 or reference books in a comfortable state, and especially when you lie down, you can see the book 10 or reference documents. In addition, the fixed state between the support plate 1 and the first arm 2 on which the inclination angle is completed can be firmly maintained by the first fixing device 3.

Further, the book 10 can be easily held regardless of the thickness and size of the book 10 by allowing the first fixing clip 7 to firmly grip the lower end of the book, ie, the lower end of the core, of the book 10. Not only can be supported, so that the parts located on both sides of the open core of the open book 10 can not be protruded forward, so that the characters of the part can be seen well.

In addition, in the case of holding the upper end of the reference document by the second fixing clip 8, not only the reference document can be held without removing the second fixing clip 8 from the support plate 1, but also the reference document. In the case of holding the lower end of the lower part of the hinge, the hinge 9 is also rotated horizontally 92 without being separated from the supporting plate 1, and the appropriate portion of the reference document by the free shandong of the lifting bracket 91.
