Description

Technical Field

[0001] This invention relates to the field of stationery, and more specifically to a reading stand with a minimum usability angle limitation function. Background Technology

[0002] A reading stand is an important component used to assist people in reading or studying. It typically includes a panel for holding books and a support frame for supporting the panel. The support frame is usually placed vertically on a table. By rotating the panel and the support frame relative to each other, the angle between the panel and the support frame is changed, thereby changing the angle between the panel and the viewer's line of sight and adjusting the reading angle. In order to minimize the space occupied by the reading stand when folded, most existing reading stands have an angle of 0° between the panel and the support frame when folded. Furthermore, existing reading stands do not have a minimum usable angle setting function, so users do not know the minimum angle between the panel and the support frame when using them for the first time. If the angle between the panel and the support frame is set too small, the books placed on the panel are too vertical and are easy to fall when flipped. Moreover, reading at this angle is not comfortable. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a reading stand with a minimum usage angle limitation function.

[0004] To achieve the above objectives, the present invention provides a reading stand with angle limiting function, comprising a panel and a support for supporting the panel. The front of the panel is provided with a spine groove, and the spine groove forms a longitudinal ridge on the back of the panel. The support includes a pole assembly and a leg assembly. The pole assembly includes a pole sleeve and a pole. The pole sleeve extends vertically in the up-down direction, and the pole is slidably inserted into the pole sleeve. The upper end of the pole is rotatably connected to the longitudinal ridge on the back of the panel.

[0005] The reading holder also includes an angle retainer disposed on the back of the panel. The angle retainer includes a slider, a slider cover, and an angle pad. The slider is slidably disposed on the back of the panel and located on one side of the upright. The slider cover is disposed on the slider and connected to the back of the panel. The angle pad is connected to the side of the slider near the upright and protrudes from the slider cover. The slider has a first working position and a second working position. When the slider is in the first working position, the angle pad is located on one side of the rotation plane of the upright. When the slider is in the second working position, the angle pad extends between the upright and the back of the panel and presses against the upright to prevent the upright from continuing to rotate toward the longitudinal bulge on the back of the panel.

[0006] Preferably, when the slider is in the second working position, the angle between the upright and the panel is 15°-25°.

[0007] More preferably, when the slider is in the second working position, the angle between the upright and the panel is 20°.

[0008] Preferably, when the slider is in the second working position, the included angle between the upright sleeve and the panel is 20°-30°.

[0009] More preferably, when the slider is in the second working position, the angle between the upright sleeve and the panel is 25°.

[0010] Preferably, the sliding direction of the slider is perpendicular to the rotation plane of the upright.

[0011] Preferably, the angle fixer further includes a spring for driving the slider to slide toward the second working position.

[0012] More preferably, a slider spring stop is provided on the inner side of the end of the slider near the angle pad, and a rearwardly protruding panel spring stop is connected to the back of the panel, with the two ends of the spring respectively abutting against the slider spring stop and the panel spring stop.

[0013] Preferably, the end of the slider away from the angle pad has a slider left and right movement protrusion.

[0014] More preferably, the slider cover has a central through hole, the extension direction of the central through hole is parallel to the sliding direction of the slider, and the left and right moving protrusion of the slider and the angle pad pass through the central through hole of the slider cover.

[0015] Preferably, the upper end of the upright is rotatably connected to the longitudinal ridge via a pivot shaft, which is the pivot shaft of the damper.

[0016] More preferably, the slider cover is bonded to the back of the panel.

[0017] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0018] The present invention provides a reading stand with angle limiting function, including a panel, a support, a vertical pole assembly, and a foot assembly. The front of the panel has a spine groove, and the spine groove forms a longitudinal ridge on the back of the panel. The upper end of the vertical pole in the vertical pole assembly is rotatably connected to the longitudinal ridge on the back of the panel. An angle fixing device is provided on the back of the panel, which includes a slider, a slider cover, and an angle pad. The slider is slidably disposed on the back of the panel and located on one side of the vertical pole. The slider cover is disposed on the slider and connected to the back of the panel. The angle pad is connected to the side of the slider near the vertical pole and protrudes from the slider cover. In use, the spring force causes the slider to slide towards the vertical pole, and the angle pad extends between the vertical pole and the longitudinal ridge on the back of the panel and presses against the vertical pole, preventing the vertical pole from continuing to rotate towards the panel, thereby limiting the minimum use angle. When using it for the first time, the user can easily set the angle between the panel and the support within a reasonable range. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0025] like Figures 1 to 7As shown, the reading stand with angle limiting function provided by the present invention includes a panel 1 and a support assembly for supporting the panel 1. The front of the panel 1 is provided with a spine groove, and the spine groove forms a longitudinal ridge on the back of the panel 1. The support assembly includes a pole assembly and a leg assembly. The pole assembly includes a pole sleeve 11 and a pole 10. The pole sleeve 11 extends vertically in the up-down direction, and the pole 10 is slidably inserted into the pole sleeve 11. The upper end of the pole 10 is rotatably connected to the longitudinal ridge on the back of the panel 1. The reading stand also includes an angle fixer disposed on the back of the panel 1. The angle fixer includes a slider 4, a spring 3, a slider cover 8, and an angle pad 7. The slider 4 is slidable. The slider 4 is mounted on the back of panel 1 and located on one side of the upright 10. The slider cover 8 covers the slider 4 and is connected to the back of panel 1. The angle pad 7 is connected to the side of slider 4 near the upright 10 and protrudes from the slider cover 8. Slider 4 has a first working position and a second working position. When slider 4 is in the first working position, angle pad 7 is located on one side of the rotation plane of upright 10. When slider 4 is in the second working position, angle pad 7 extends between upright 10 and the longitudinal bulge on the back of panel 1 and presses against upright 10 to prevent upright 10 from continuing to rotate toward the longitudinal bulge on the back of panel 1. Spring 3 has the tendency to drive slider 4 to slide toward the second working position.

[0026] The advantage of this design is that, during use, the elastic force of the spring 3 drives the slider 4 to slide towards the upright 10, inserting the angle pad 7 between the upright 10 and the longitudinal bulge on the back of the panel 1 and pressing against the upright 10, preventing the upright 10 from continuing to rotate towards the longitudinal bulge on the back of the panel 1, thereby limiting the minimum operating angle. When using it for the first time, the user can easily set the angle between the panel 1 and the bracket within a reasonable range.

[0027] In this embodiment, when the slider 4 is in the second working position, the angle between the upright sleeve 11 and the longitudinal protrusion on the back of the panel 1 is 20°-30°. Furthermore, when the slider 4 is in the second working position, the angle between the upright sleeve 11 and the longitudinal protrusion on the back of the panel 1 is 25°.

[0028] In another embodiment, when the slider 4 is in the second working position, the angle between the upright 10 and the longitudinal protrusion on the back of the panel 1 is 15°-25°. Further, when the slider 4 is in the second working position, the angle between the upright 10 and the longitudinal protrusion on the back of the panel 1 is 20°.

[0029] In this embodiment, the sliding direction of the slider 4 is perpendicular to the rotation plane of the upright 10.

[0030] In order to make the spring 3 have the tendency to drive the slider 4 to slide to the second working position, so that the slider 4 moves to the second working position at the first moment when the upright sleeve 11 rotates relative to the panel 1, in this embodiment, the slider 4 is provided with a slider spring stop 5 on the inner side of the end near the angle pad 7, and the back of the panel 1 is connected with a rearward protruding panel spring stop 2. The two ends of the spring 3 are respectively pressed against the slider spring stop 5 and the panel spring stop 2.

[0031] To facilitate the reset of the slider 4 and the folding of the reading holder, in this embodiment, the end of the slider 4 away from the angle pad 7 is provided with a slider left and right movement protrusion 6, and the slider cover 8 is provided with a slider cover middle through hole 9. The extension direction of the slider cover middle through hole 9 is parallel to the sliding direction of the slider 4, and the slider left and right movement protrusion 6 and the angle pad 7 are inserted into the slider cover middle through hole 9.

[0032] In this embodiment, the upper end of the upright 10 is rotatably connected to the longitudinal ridge via a pivot 12, which is preferably the pivot of a damper. Furthermore, the slider cover 8 is bonded to the back of the panel 1.

[0033] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
