It is about a portable reading stand that allows the plate unit 30 to be retracted and has a flat shape when the pedestal and the base plate unit are accommodated, but has a structure in which the pedestal 20 is retracted or withdrawn from the pedestal receiving groove 110. It is obvious that it can be applied to all reading tables.

Referring to Figures 2 to 4, the stand coupling device for a reading table according to the present invention is a device that couples the top and the base of a reading table, and the stand coupling portion 40 formed in the pedestal receiving groove formed on the top plate is coupled with the pedestal coupling portion. It may be configured to include a fastening protrusion 50 formed on the side of the pedestal and a ring member 60 that is inserted into the fastening protrusion and is frictionally engaged when the pedestal coupling part and the fastening protrusion are coupled.

The fastening protrusion 50 includes a base 510 formed on a side of the pedestal and a fastening protrusion 520 protruding on the base. Here, the fastening protrusion 520 may be configured to have a smaller cross-sectional diameter than the base end 510 so that a step is formed between the base end 510 and the fastening protrusion 520.

The ring member 60 is coupled by being inserted into the fastening protrusion 520 until it comes into contact with the base end 510. Here, the ring member 60 may be made of an elastic material such as rubber so that it is compressed and frictionally coupled when coupled.

The pedestal coupling portion 40 is configured to receive a fastening protrusion 50 to which the ring member 60 is coupled, and includes a fastening protrusion receiving portion 410 for receiving the fastening protrusion and a fastening protrusion receiving portion 410 for receiving the ring member. It may be configured to include a ring member receiving portion 420.

The fastening protrusion receiving portion 410 forms a fastening protrusion receiving groove, and the fastening protrusion is accommodated in contact with one side of the fastening protrusion receiving portion 410, and the ring member receiving portion 420 accommodates the ring member. A groove is formed, and the ring member 60 is accommodated in the ring member receiving portion 420.

Here, the width of the ring member receiving portion 420 is configured to be the same as the thickness of the ring member 60, and a portion of the proximal end 510 is inserted into the ring member receiving portion 420.

More specifically, the fastening protrusion inlet portion of the ring member receiving portion 420 is formed with proximal protrusions 421 at the upper and lower portions, and the height between the upper and lower proximal proximal proximal protrusions is formed so that the height of the proximal end 510 is the same. As a result, a portion of the proximal end 510 is inserted into the ring member receiving portion 420 and the ring member 60 can be fastened while pressing from the side.

Accordingly, when the fastening protrusion is fastened to the pedestal coupling portion, the ring member is compressed from both sides and is deformed to extend in the vertical direction, resulting in frictional coupling.

Accordingly, the fastening protrusion is strongly coupled to the pedestal coupling portion, and the pedestal can be unfolded or folded only by applying a certain force when rotating the fastening protrusion, so no noise is generated during the process of folding or unfolding the pedestal.

The top plate 10 of the reading desk according to the present invention may be configured by combining a back plate 10A and a front plate 10B to have a hollow structure for weight reduction.

Referring to FIG. 5, the top plate 10 of the reading stand according to the present invention may be composed of a rear plate 10A and a front plate 10B, and as a result, the stand coupling portion 40 is formed on the rear plate. It may be configured to be separately composed of a stand coupling portion (40A) and a front stand coupling portion (40B) formed on the front plate and then combined.

When the rear pedestal engaging portion 40A and the front pedestal engaging portion 40B are joined together, a fastening protrusion accommodating portion and a ring member accommodating portion may be formed.

Here, the first ring support jaw 412A serves to support one side of the ring member accommodated in the ring receiving groove, and the first base support jaw 413A is configured to have a lower height than the first ring support jaw. This allows a portion of the base end 510 of the fastening protrusion to be inserted into the first ring receiving groove 411A.

Accordingly, since the first ring receiving groove 411A is configured to have the same width as the ring member 60, a portion of the proximal end 510 is inserted into the first ring receiving groove 411A and presses the ring member 60. I do it. That is, since the ring member 60 is fastened while strongly pressing between the first ring support jaw 412A on one side of the ring member 60 and the base end 510 on the other side of the ring member, a strong fixing force can be maintained. Then, the ring member undergoes elastic deformation in which the width narrows and the height increases, and the ring member comes into contact with the bottom of the first ring receiving groove 411A and engages in frictional engagement.

Here, the first ring support jaw 412A may have a groove 412A-1 formed in contact with a portion of the fastening protrusion 520.

A second ring support jaw 412B for supporting the member and a second base support jaw formed on the other side of the second ring receiving groove and formed at a lower height than the support jaw so that a portion of the base end is inserted into the second ring receiving groove. It may be configured to include (413B).

Here, the second ring support jaw 412B serves to support one side of the ring member 60 accommodated in the ring receiving groove, and the second base support jaw 413B serves as the second ring support jaw 412B. ) and allows a portion of the base end 510 of the fastening protrusion to be inserted into the second ring receiving groove 411B.

Accordingly, since the second ring receiving groove 411B is configured to have the same width as the ring member 60, a portion of the proximal end 510 is inserted into the second ring receiving groove 411B and pressurizes the ring member 60. I do it. That is, since the ring member 60 is fastened while strongly pressing between the second ring support jaw 412B and the base end 510, a strong fixing force can be maintained. In addition, the ring member 60 undergoes elastic deformation in which the width narrows and the height increases, and the ring member 60 comes into contact with the bottom of the second ring receiving groove 411B and engages in frictional engagement.

The second fastening protrusion receiving portion 420B is formed integrally with the second ring support jaw 412B, and has a second upper part extending from the second ring support jaw 412B and having a shape that contacts the remaining portion of the fastening protrusion. It may be configured to include a ring receiving groove.

When the rear pedestal coupling portion 40A and the rear pedestal coupling portion 40B are combined and coupled, the second ring receiving portion 420B is inserted into the fastening protrusion frame 421A of the first fastening protrusion receiving portion and accommodates the second ring. The fastening protrusion abuts and is fixed between the groove 420B and the groove 412A-1 of the first ring support jaw 412A.

The first and second ring receiving grooves, the first and second ring support jaws, and the first and second base support jaws are composed of pairs, and when the front support coupling portion and the rear support coupling portion are combined and combined, one ring receiving groove and ring are formed. A support jaw and a base support jaw are formed.

Referring to Figure 6, first, the ring member is inserted into the fastening protrusions 50 formed on both sides of the pedestal.

More specifically, the fastening protrusion 50 includes a proximal end 510 and a fastening protrusion 520 having a step difference from the proximal end 510, and the fastening protrusion 520 is provided through a penetrating portion of the ring member 60. Insert and push the ring member 60 until it abuts the base end 510.

Next, the fastening protrusion 50 is seated on the rear stand coupling portion 40A as shown in FIG. 7.

More specifically, the rear stand engaging portion 40A consists of a pair formed on both sides of the stand, and the fastening protrusion 520 is the first fastening protrusion receiving portion 420A of the rear stand engaging portion 40A. 1 When received in the fastening protrusion receiving groove 422A, the ring member 60 is seated in the first ring receiving groove 411A, and the proximal end 510 is partially inserted into the first ring receiving groove 411A, thereby forming the ring member 60. (60) is pressed from both sides, frictional engagement occurs due to elastic deformation, and the fastening protrusion 50 is strongly coupled to the pedestal coupling portion 40A.

In this state, when the front plate (10B) is coupled to the rear plate (10A), the front stand coupling portion (40B) and the rear stand coupling portion (40A) are combined to fix the fastening protrusion portion (50).

Accordingly, the pedestal 20 is strongly fixedly coupled to the side of the pedestal receiving groove 110 by the pedestal coupling device according to the present invention, and the pedestal can be unfolded or folded only by applying a certain force due to frictional engagement of the ring member 60. No noise is generated during the process of unfolding or folding the stand.

Figures 8 and 9 schematically show a bookshelf fixing device for a reading table according to a preferred embodiment of the present invention, and Figures 10 to 12 show a state in which the bookshelf according to the present invention is fixed by the bookshelf fixing device. will be.

Referring to FIGS. 8 to 12, the bookshelf fixing device 70 for a reading stand according to the present invention has a through hole 710 that penetrates into the hollow interior through the front of the stand and into which the anchor 810 of the bookshelf is inserted. A fixation unit that is connected to a through hole to accommodate a fixing unit, a fixing unit accommodating part 720, and a bookshelf anchor 810 inserted into the fixing unit accommodating part and inserted through the through hole penetrates to secure the bookshelf. It may be configured to include a unit 730.

In the bookshelf according to the present invention, an anchor 810, one end of which is formed in the shape of a straight wire, is inserted into a through hole 710 formed in the front of the pedestal, so that the bookshelf 80 is fixed.

However, when the size of the through hole 710 is simply formed to be smaller than the cross-section of the anchor 810 of the bookshelf and fastened by force fitting due to the difference in cross-sectional size of the anchors 810 of the bookshelf, the above-mentioned There was a problem that the book holder easily came off as the through hole (710) became loose.

Therefore, in the present invention, the anchor 810 of the book handle is accommodated in the fixing unit receiving portion 720 connected to the through hole 710 with the fixing unit 730 having a central portion penetrated through the through hole 710. When penetrating through the fixing unit 730, the fixing unit accommodating portion 720 prevents the fixing unit 730 from being detached and prevents the fixing force from being lowered due to use of the book holder 80, thereby preventing the book holder 80 from being deteriorated. can be firmly fixed.

Additionally, the fixing unit accommodating part 720 may be configured to include a fixing unit fixing part to prevent the fixing unit 730 from being pushed or separated.

As shown in Figure 5b, the fixing unit accommodating part 720 has a side wall 721 formed on the edge to provide a space for accommodating the fixing unit 730, and an opening 722 is formed in the lower center for insertion. The anchor 810 of the book holder may extend below the fixing unit receiving portion 720. In particular, the lower walls 721a of the side walls formed on both sides of the opening 722 can maintain a strong fixing force by preventing the received fixing unit 730 from being pushed downward or separated.

Here, the lower wall 721a serves as a fixing unit fixture that prevents the fixing unit 730 from being pushed downward or separated.

It may further include a reinforcing wall 723 extending downward from the lower wall 721a below the fixing unit accommodating portion 720, and the anchor 810 of the bookshelf is formed by the reinforcing wall 723. is guided to the lower part, prevents the fixed anchor from moving left and right, and plays a role in reinforcing the strength of the lower wall (721a), preventing destruction or damage of the lower wall (721a) even if a large force is applied to the lower wall (721a). It can be prevented.

The fixing unit 730 has a fixing washer through-hole 731a at the center and is configured in a cylindrical shape, and has a fixing washer 731 for fixing the anchor and a snap ring through-hole 732a at the center, and is located between the inserted anchor. It may be configured to include a snap ring 732 that provides friction to prevent the anchor from falling off.

Referring to FIG. 13, the snap ring 732 may be configured to have a dish shape by having a convex portion 732b that protrudes downward around the snap ring through hole 732a.

The snap ring 732 provides friction that cancels out the force acting in the opposite direction when the anchor 810 inserted into the snap ring through hole 732a is applied in the opposite direction. It is responsible for maintaining the fixing force of the anchor 810.

The snap ring 732 may be composed of one piece, but may be composed of multiple pieces to increase the fixing force of the anchor 810. If too many snap rings 732 are included, the anchor 810 may be damaged due to excessively large magic force. Since insertion may be difficult, it is preferable to configure it in two pieces as in the embodiment of FIG. 7.

The height of the fixing unit 730 can be made the same or greater than the height (H) inside the fixing unit accommodating part 720. When the height of the fixing unit 730 is made large, the fixing unit 730 The fixing force of the anchor 810 can be increased by being tightly fixed inside the fixing unit receiving portion 720.

In addition, the fixing unit 730 may be composed of only a fixing washer 731 or a snap ring 732. The fixing washer 731 has excellent fixing force, but when it becomes loose through use, the friction force decreases and the anchor 810 You can break away. On the other hand, the snap ring 732 can maintain a fixing force by maintaining friction when a force acts in the opposite direction to which the anchor 810 is inserted due to the convex portion 732b around the snap ring through hole 732a, so the anchor 810 It is possible to prevent the departure of . Therefore, it is preferable that the fixing unit 730 includes the snap ring 732 alone or the fixing washer 731 and the snap ring 732.

Here, when the fixing unit 730 is composed of only the snap ring 732, it is obvious that the height H of the fixing unit accommodating part 720 must be adjusted to match the height of the snap ring 732.

Hereinafter, we will look at the process of installing the bookshelf fixing device according to a preferred embodiment of the present invention.

First, the fixing unit 730 is inserted into the fixing unit receiving portion 720.

More specifically, the fixing washer 731 and snap ring 732 forming the fixing unit 730 are sequentially inserted into the fixing unit accommodating part 720.

Here, when the height of the fixing washer 731 and the snap ring 732 is formed to be larger than the height of the fixing unit accommodating part 720, the fixing washer 731 and the snap ring 732 are forced to accommodate the fixing unit. It can be strongly fixed within the part 720.

When the fixing unit 730 is inserted into the fixing unit receiving portion 720 as described above, the through hole 710, the fixing washer through hole 731a, and the snap ring through hole 732a are aligned in a straight line.

In this state, the anchor 810 of the bookshelf is inserted into the through hole 710 of the bookshelf, penetrates through the fixing washer through hole 731a and the snap ring through hole 732a, and is inserted into the lower part of the fixing unit receiving portion 720. The anchor 810 is completely pushed into the lower part through the opening 722.

Through the above process, the book holder 80 is firmly fixed to the support.

When the bookshelf 80 is fixed to the bookshelf fixing device 70 as described above, even if a force acts in the direction opposite to the direction in which the anchor 810 of the bookshelf is inserted, the fixing washer 731 and The anchor 810 can be prevented from coming off by offsetting the force acting in the opposite direction by the double fixing means of the snap ring 732.

In particular, with both ends of the snap ring 732 in contact with the bottom wall 721a of the side wall of the fixing unit receiving portion 720, the convex portion 732b provides cushioning when force acts in the opposite direction to which the anchor 810 is inserted. Since the force can be offset by friction, it is possible to prevent the anchor 810 from coming off.

In the end, the fixing unit receiving portion 720 prevents the left, right, top and bottom fixing units 230 from being separated, and the through hole 710, the fixing washer through hole 731a, and the snap ring through hole 732a are aligned in a straight line. This makes it easier to insert the bookshelf anchor.

In addition, there is a reinforcing wall 723 connected to the bottom wall 721a, so that the strength of the bottom wall 721a is strengthened, so that the bottom wall 721a is not damaged even if force is applied when inserting the anchor 810 of the book holder into the fixing unit. The fixing unit 720 can be easily inserted while preventing it from falling to the bottom, and once the anchor 810 is installed, the fixing force of the anchor is prevented from being reduced by the fixing unit 730 accommodated in the fixing unit receiving portion 720. This can prevent the anchor 810 from being separated.

The fixing washer through hole 751a is a space where the anchor 810a of the bookshelf is inserted and fixed, and may be configured to have a diameter equal to that of the anchor 810a in order to increase the fixing force by closely adhering the anchor 810a. The holding power can be increased by insertion.

As the anchor 810a is inserted into the fixing washer through hole 751a in close contact, the contact area expands, and the adhesive force becomes stronger, so that the anchor 810a can sufficiently resist the force of detachment, thereby maintaining the fixing force.

The fixing unit accommodating part 720a is formed in a concave shape corresponding to the shape of the fixing washer 751 inserted into the lower part, but may be configured to have a pressing part 721a protruding downward at the inner upper part.

The pressing portion 721a is formed to be smaller than the width of the fixing unit receiving portion 720a, and is formed to contact only the snap ring 752, so that the convex portion 752b of the snap ring 752 is pressed and the snap ring penetrating portion 752a is formed. Since pressure is applied to narrow the anchor, the anchor 810a can be strongly fixed.

In the embodiments of FIGS. 15 and 16, the fixing unit is configured in the form of a cylinder, but it may be configured in various shapes such as an elliptical column or a polygonal column.

The fixing washer 751 is configured in an embossed shape corresponding to the fixing unit receiving portion 720a, and when the pedestal 20a is fixed to the top plate 10a, the fixing washer 751 is connected to the top plate 10a. Because it is in close contact, the fixing washer 751 is fixed while preventing slipping due to the pressure of the book holder 80a.

The snap ring 752 may have the same shape as the snap ring 732 shown in FIG. 7, and is configured to have a dish shape by having a convex portion 752b that protrudes downward around the snap ring through hole 752a. It can be.

The fixing washer 751 has excellent fixing power, but if it becomes loose due to use, the friction force may decrease and the anchor 810a may come off. On the other hand, the snap ring 752 can maintain a fixing force by maintaining friction when a force acts in the opposite direction to which the anchor 810a is inserted due to the convex portion 752b around the snap ring through hole 752a, so the anchor 810 It is possible to prevent the departure of . Therefore, it is preferable that the fixing unit 750 includes a fixing washer 751 and a snap ring 752.

The snap ring 752 may be composed of one piece, but may be composed of multiple pieces to increase the fixing force of the anchor 810a. If too many snap rings 752 are included, the anchor 810a may be damaged due to excessively large magic force. Since insertion may be difficult, it is preferable to configure it in two pieces as in the embodiment of FIG. 13.

The snap ring 752 may be coupled to the upper or lower part of the fixing washer 751, and may be configured to be coupled one to the upper and lower parts.

The fixing washer 751 may be configured to include a snap ring receiving portion 751b at a portion where the snap ring 752 is coupled.

Here, the snap ring receiving portion 751b serves as a fixing unit fixture that prevents the snap ring 752, which serves as a fixing unit, from being pushed or separated from the lower part.

The snap ring receiving portion 751b may be configured to have a concave or convex shape at a portion where the snap ring 752 abuts.

That is, when the snap ring 752 is coupled to the upper part of the fixing washer 751, as shown in FIGS. 15 and 16, the snap ring receiving portion 751b is configured to have a convex shape because it comes into contact with the lower part of the snap ring 752, and the fixing washer ( 751) When coupled to the lower part, the snap ring receiving portion 751b contacts the upper part of the snap ring 752, so it may be configured to have a concave shape.

Also, since the area where the anchor (810a) of the bookshelf is coupled within the fixing washer (751) increases, it can be coupled with a stronger fixing force.

Therefore, in the embodiments of FIGS. 15 and 16, the length of the fixing washer 751 is longer than that of the fixing washer 731 according to the embodiment of FIG. 13, so the area where the anchor 810a of the bookshelf is coupled is wider, making it stronger. It can have fixing power.

Figure 20 schematically shows how a bookshelf according to a preferred embodiment of the present invention is fastened to a pedestal, and the pedestal is fastened to a top plate.

Referring to FIG. 20, first, the fixing washer 751 with the snap ring 752 inserted is inserted into the fixing unit receiving portion 720a of the pedestal 20a.

Then, the anchor 810a of the book holder 80a is inserted through the anchor hole 721a of the base, and is fixed by being forced into the fixing washer through hole 751a at the bottom of the anchor hole 721a. When the anchor 810a is forcibly inserted until it is completely inserted, the book holder 80a is integrally fixed to the stand 20a.

It is then fixed to the top plate (10a) through the fastening groove (230a) of the pedestal using a bolt or piece.

Accordingly, as shown in FIGS. 21 and 22, the stand 20a on which the book handle 80a is integrally formed is fixed to the top plate 10a.

Here, the top plate 10a in contact with the pedestal 20a serves as a fixing unit fixture that prevents the fixing unit 750 from being pushed or separated from the lower part.
