Description

Technology Field

[0001] The present invention relates to a reading stand with a dual top plate structure capable of two-stage angle adjustment, and more specifically, to a reading stand with a dual top plate structure composed of two upper and lower sections that allows for three-dimensional arrangement of various media and enables two-stage angle adjustment and complete horizontal folding to suit the physical characteristics of the user. Background Technology

[0002] Traditional reading stands have been manufactured with a single top plate structure, primarily using wood, plastic, or medium-density fiberboard (MDF).

[0003] These conventional reading stands were limited to an average width of about 35 cm, so there was almost no extra space when large books such as textbooks or law books were spread out, and there were significant spatial constraints, especially when placing a tablet PC next to the book to watch lectures.

[0004] Furthermore, due to the nature of MDF material, which consists of wood fibers mixed with adhesive and compressed, it has low durability and is susceptible to moisture, exhibiting limitations in terms of long-term reliability, such as the tabletop warping or corners easily breaking during prolonged use.

[0005] Meanwhile, according to research from an ergonomic perspective, when humans study while sitting, their gaze naturally forms about 10° to 20° below the horizon. However, most conventional reading stands have a narrow angle adjustment range or unstable fixing mechanisms, making it difficult for users to set the viewing angle to suit their eyesight and body type.

[0006] As a result, users maintain a posture with their heads excessively bowed for a long period, which leads to increased cervical flexion and tension in the shoulder muscles, becoming a major cause of physical ailments such as forward head posture or myofascial pain syndrome.

[0007] In addition, conventional reading stands are often designed as a single unit where the support blocks the entire width, which restricts wrist movement during writing and causes the elbow to protrude outside the stand, resulting in an unbalanced posture and discomfort.

[0008] In addition, due to the lack of a dedicated space to safely store writing instruments, there were numerous factors that disrupted the continuity of learning, such as pens rolling away or getting lost.

[0009] Therefore, there is a need to develop an innovative reading stand that provides a wide learning area while increasing material strength to prevent deformation, and integrates a scientific angle design and mechanical folding function that considers user health. Prior art literature

[0010] Published Patent Application No. 10-2023-0001446 The problem to be solved

[0011] The present invention was devised to solve the problems of the prior art, and the problem to be solved by the present invention is as follows.

[0012] First, the goal is to secure sufficient study space that allows for the stable placement of books and mobile devices simultaneously through a dual tabletop structure with two-stage angle adjustment. This aims to create an environment where users can study while simultaneously viewing multiple reference materials.

[0013] Second, the visual visibility is enhanced through a dual structure of the first and second upper plates. The first upper plate is designed to maintain an ergonomically derived 20° inclination angle to alleviate the burden on the cervical spine, while the second upper plate aims to secure an optimal field of view through a two-stage angle adjustment hinge.

[0014] Third, the goal is to secure significantly improved bending strength and load-bearing capacity compared to ordinary wood by applying a lamination method for birch plywood. The main objective is to fundamentally prevent material warping caused by changes in temperature and humidity by cross-lamining the fiber directions of birch veneers, and to ensure that no minute vibration or sagging occurs on the tabletop even when heavy textbooks are placed on it.

[0015] Fourth, a high-pressure melamine resin coating layer is formed on the surface of the top plate to provide strong wear resistance and scratch resistance. The aim is to complete a decorative plate structure that can be used hygienically for a long period of time by protecting the surface from everyday writing pressure or friction generated when moving books and by enhancing antibacterial functions.

[0016] Fifth, to enhance usability, the length of the bottom support is limited to 26 cm and positioned in the center, thereby opening up writing spaces on the left and right sides. This allows both left-handed and right-handed users to comfortably write directly on the top surface without wrist interference. Additionally, it includes a detailed structural improvement by providing a pen groove to prevent the writing instrument from slipping out.

[0017] Sixth, the goal is to maximize space efficiency by implementing a folding mechanism that allows the second top plate to be completely folded downwards parallel to the first top plate when not in use. The key technical challenge is to provide variability so that horizontal space is secured when the top plate is folded, enabling it to function as a laptop or a wide workbench. means of solving the problem

Specific details for implementing the invention

[0047] In describing the specific details for implementing the present invention, the explanation will be based on preferred embodiments.

[0048] However, this does not mean that the present invention is limited to specific embodiments, and it should be understood that it includes all modifications, equivalents, or substitutions that fall within the spirit and technical scope of the present invention.

[0049] Furthermore, the purposes and effects presented in this invention do not imply that specific embodiments must include all of them or only such effects, and the scope of the rights of this invention should not be understood as being limited by them.

[0050] Unless otherwise defined, all terms used in describing the present invention are preferably interpreted as being consistent with their dictionary meanings and the meanings universally understood in the context of the relevant technology by those skilled in the art to which the present invention belongs.

[0051] Hereinafter, an embodiment of a reading stand with a dual top plate structure capable of two-stage angle adjustment according to the present invention will be described in detail with reference to the attached drawings. In describing with reference to the attached drawings, identical or corresponding components are given the same reference numerals, and redundant descriptions thereof will be omitted.

[0052] This will be explained with reference to FIGS. 1 to 5.

[0053] The reading stand of the present invention, having a dual top plate structure capable of two-stage angle adjustment, comprises: a first top plate (10) having a high-pressure melamine resin coating layer formed on the surface of a birch plywood material; a pair of side plates (20) each vertically coupled to both ends of the first top plate (10) to support the first top plate (10) at an angle of inclination of 20° from the ground; a bottom support (30) formed protruding from the lower central area of ​​the first top plate (10) to support the bottom of a book and secure writing spaces for wrist rest on the left and right sides; a pen groove (40) formed in a recess at the lower tip of the first top plate (10) to prevent rolling of a writing instrument; a hinge part (50) symmetrically formed on the upper inner surface of the side plate (20) to support the second top plate (60) so that it can rotate and two-stage angle adjustment; and a first by means of the hinge part (50). It is configured to include a second top plate (60) that is coupled to the top plate (10) so as to be rotatable independently and provides an auxiliary mounting space.

[0054] The first upper plate (10) is formed with a horizontal length of 500 to 600 mm and a vertical length of 400 to 450 mm. These dimensions are significantly expanded compared to conventional standard reading stands, and the area is optimized for checking two A4 documents simultaneously or placing a tablet PC next to a textbook.

[0055] Meanwhile, the first top plate (10) is fixed at an angle of inclination of 20° with the ground by the side plates (20) connected to both sides.

[0056] According to ergonomic research results, when the tabletop angle is 20° during reading, the pressure applied to the cervical spine is reduced by approximately 40% compared to a flat state, and the tension of the accommodative muscles, which determine eye fatigue, records the lowest levels. This effectively prevents the so-called "turtle neck" posture by inducing the user's natural gaze to remain within a range of 10° to 20° below the horizon.

[0057] The internal material of the first top plate (10) is high-quality birch plywood. Birch wood has a very high density and a dense structure, providing the best strength as a furniture material.

[0058] In this invention, a multilayer laminated structure is adopted in which birch veneers of approximately 1.0 mm are arranged so that their fiber directions intersect at 90°, and then an eco-friendly resin adhesive is applied and the veneers are compressed under high pressure.

[0059] This orthogonal lamination method cancels out the inherent shrinkage and expansion properties of wood, preventing deformation or warping caused by temperature changes and humidity, and not only secures bending strength of about 1.5 times or more compared to ordinary solid wood of the same thickness, but also achieves structural reliability that firmly supports heavy book loads without deformation of the tabletop.

[0060] In addition, a high-pressure melamine resin coating layer is formed on the outer surface of the top plate to enhance functionality.

[0061] High-pressure melamine resin is a high-performance surface material formed by layering kraft paper and design printed paper, each impregnated with melamine resin and phenolic resin respectively, and then compressing them at a high temperature of about 150° and a high pressure of 100 kg / ㎠ or more.

[0062] This high-pressure melamine resin coating layer has a thickness of 0.7 mm or more and a surface hardness approaching 9H, providing wear resistance that prevents scratches from occurring even under everyday writing pressure or friction with metal instruments. In addition, the resin particles are bonded at a high density, providing moisture resistance that prevents water or contaminants from penetrating into the interior, and by mixing antimicrobial agents during the impregnation process, it possesses hygienic properties that inhibit bacterial growth on the surface.

[0063] The above side plate (20) is made of the same high-density birch plywood as the first top plate (10) and is positioned vertically at the left and right sides of the first top plate (10) to fix and support the inclination of the top plate at 20°.

[0064] The above 20° angle is the optimal angle that, through ergonomic research, keeps the user's gaze within a downward range of 10° to 20°, thereby significantly reducing the load on the cervical spine compared to a flat state.

[0065] The side plate (20) may have a side shape in the form of a triangle or a trapezoid to maintain the angle and may be combined with a rear support to form a strong triangular support structure.

[0066] In addition, the side plate (20) is provided with a handle hole (201) for user mobility convenience.

[0067] It should be noted in advance that the handle hole (201) is formed by penetrating the plate surface of the side plate (20) and is perforated with dimensions of 100 to 120 mm in width and 30 to 40 mm in height, taking into account the average hand width of adult men and women, but the shape of the handle hole (201) is not limited.

[0068] The inner edge of the handle hole (201) is finished with a smooth curved surface through sanding with a grit of 400 or higher and chamfering, thereby minimizing pressure on the user's hand when gripping and preventing injury.

[0069] In particular, the position of the handle hole (201) is positioned to correspond to the mechanical center of gravity of the reading stand, thereby providing a sense of balance that prevents the product from tilting forward or backward when lifted.

[0070] The lower support (30) is formed to protrude from the bottom of the first top plate (10) to prevent the book from falling.

[0071] It is preferable that the lower support (30) has a horizontal length of 200 to 300 mm and is placed only in a limited manner in the central part of the first upper plate (10) with a total width of 500 to 600 mm.

[0072] This partial arrangement design is an ergonomic consideration to relieve the discomfort caused by the wrist and forearm parts getting caught on the lower support (30) when the user writes on the first upper plate (10) of the reading stand.

[0073] That is, by utilizing the empty space on the left and right sides without the bottom support (30) as a dedicated writing area, both left-handed and right-handed users can secure a free writing radius as on a flat desk.

[0074] The above pen groove (40) is formed by being recessed in the upper central area of ​​the first top plate (10) in a horizontal direction.

[0075] That is, the pen groove (40) is formed with a length of 400 to 500 mm and a width of 7 to 20 mm in the horizontal direction, and it is preferable to round both ends. This prevents the writing instrument from rolling or coming off and performs a sophisticated convenience function that increases immersion in learning by allowing the writing instrument needed during learning to be immediately taken out and used.

[0076] The hinge portion (50) is symmetrically formed on the upper inner surface of the side plate portion (20) and includes a hinge groove (501) and a hinge shaft (502) to support the second upper plate portion (60) so that it can be rotated and adjusted to a two-stage angle.

[0077] The hinge groove (501) is formed on the inner surface of the side plate (20) and is configured to include a pivot groove (501a) formed in an arc shape and a pair of fixed grooves (501b) formed in the middle and one end of the pivot groove (501a).

[0078] The above hinge shafts (502) are formed such that a plurality of them protrude spaced apart from the side of the second upper plate (60) and are inserted into the hinge groove (501), moving along the hinge groove (501) to enable rotation of the second upper plate (60) and two-stage angle fixation.

[0079] For example, when multiple hinge shafts (502) are all positioned within the rotation groove (501a), the second upper plate (60) can be rotated.

[0080] As another example, when multiple hinge axes (502) are each positioned within different fixing grooves (501b), the second upper plate (60) is fixed at a first angle, and at this time, it is preferable that the second upper plate (60) maintain an angle of inclination of 110 to 130° from the ground.

[0081] As another example, when one hinge shaft (502) is positioned in a fixed groove (501b) formed at one end of a pivot groove (501a) and another hinge shaft (502) is positioned within the pivot groove (501a), the second upper plate (60) is fixed at a second angle, and at this time, it is preferable that the second upper plate (60) maintains an angle of inclination of 130 to 150° from the ground.

[0082] The second upper plate (60) is connected to the first upper plate (10) by a hinge part (50) so as to be rotatable independently, thereby providing an auxiliary mounting space.

[0083] That is, the second upper plate (60) is installed independently so as to be rotatable on the upper side of the first upper plate (10), and it is preferable that it be formed with a width of 490 to 590 mm and a length of 150 to 300 mm, which is smaller than that of the first upper plate (10).

[0084] Accordingly, the second upper plate (60) is mainly used for mounting a tablet PC, a mobile device for watching videos, or a small reference book.

[0085] In addition, the second upper plate (60) can be angle-adjusted in two stages by the torque-holding force of the hinge part (50), and when not in use, it rotates downward to have a horizontal folding structure that is in close contact parallel to the upper front surface of the first upper plate (10).

[0086] In this state, the reading stand forms a single wide flat space without any protrusions on the top, which not only allows it to function as a wide writing workspace without obstructing the view of the screen when a laptop is placed, but also significantly reduces its volume during storage and portability, thereby maximizing the efficiency of space utilization.

[0087] Although the present invention has been described above with respect to limited embodiments, the scope of the present invention is not limited thereto. Changes and modifications to the present invention are possible by a person skilled in the art without departing from the technical concept and scope of the claims of the present invention, and such changes and modifications should be deemed to fall within the scope of the present invention as equivalents.
