Abstract
Description
Folding table for car laptop stand
[0001] The present invention relates to a folding table applicable to a laptop stand for a vehicle, and more particularly, to a folding table for a laptop stand for a vehicle, which can be installed and used in a single-stage or two-stage manner as needed while the laptop stand is installed on a handlebar while the vehicle is stopped, so that a laptop, mouse, documents, etc. can be placed on it and used, thereby maximizing convenience, and can be easily folded and stored after use, thereby maximizing portability and storage.
[0002] Recent laptops are easy to carry, allowing them to be used anywhere, and they have the advantage of being able to be used even inside a car.
[0003] Drivers use laptops in cars when the car is stopped and stationary, and they usually use them by placing them on their laps while sitting in the seat.
[0004] However, as mentioned above, using a laptop has the disadvantage of not only being inconvenient because the driver has to use it by raising his or her knees and resting it on them, but also the stability of the stand is reduced because the support of the laptop shakes when working with it on the knees.
[0005] In addition, it is difficult to install a laptop stand in the driver's seat where the car steering wheel is formed. When the driver stops to work on the laptop, he or she has to rely on the steering wheel, twist his or her body excessively to avoid the steering wheel, or adjust the seat to bend over and maintain a bad posture when using the computer, which causes fatigue.
[0006] Accordingly, in order to enable the driver to conveniently use a laptop while maintaining a correct posture, a laptop stand that can be easily attached and detached from the steering wheel is required, and a laptop stand that can be quickly removed from the steering wheel when in use and safely drive the car is required.
[0007] Although various laptop stands have been proposed in the past, such as Patent Document 1, which presents a simple table that can be used by passengers in the rear seats of a vehicle, provides a simple table for passengers in the rear seats of a vehicle that can provide convenience to passengers in the rear seats of a vehicle, but it has the disadvantage of having insufficient space to place a laptop and being a simple table that can be used to simply spread out documents, which limits the scope of use.
[0008] Patent document 2 simply has a laptop stand function and provides a separate file holder for viewing simple documents, but it does not provide a mouse movement space for mouse operations without using the laptop's touchpad and a work space for viewing thick documents while unfolding them, which causes inconveniences in working with the laptop.
[0009] In addition, there is no means to prevent the laptop from sliding down when the laptop is placed on the stand at an angle that is adjusted, so when the angle of the stand is large, there is a disadvantage in that the laptop may slide down while working, which is inconvenient during work.
[0010] Patent Document 3 provides a table that can be used as a reading stand, which can be mounted on the steering wheel or behind the seat in a car, or used as a simple table, or used as a reading stand on a desk or a regular table, and which can be folded thinly after use, making it convenient to carry and store. However, like Patent Documents 1 and 2, it has the disadvantage of being limited to simple use as a reading stand or a laptop stand due to the limited work space, and has the disadvantage of having a complex structure, making installation cumbersome.

[0016] The present invention was developed to solve the problems in the above-mentioned prior art.
[0017] The purpose of the present invention is to provide a foldable table for a vehicle laptop stand that can be used while mounted on a laptop stand installed on the steering wheel of a vehicle, and can be used in one or two stages of unfolding to a required width. This allows for convenient placement of a mouse, documents, etc. while working on a laptop, thereby providing convenient work, and the table can be easily folded and stored after use, maximizing convenience in carrying and storage.
[0018] The purpose of the present invention is to provide a folding table for a laptop stand for a vehicle that ensures convenience by preventing the laptop from sliding down due to use by blocking the laptop from sliding down due to the slope according to the laptop stand.
[0019] The purpose of the present invention is to provide a folding table for a laptop stand for a vehicle that can maintain a horizontal flat state when unfolded, thereby providing a table that is consistently horizontal without shaking during use, thereby ensuring reliability.
[0020] The purpose of the present invention is to provide a folding table for a vehicle laptop stand that is convenient for universal installation on a laptop stand and maximizes reliability by preventing the stand from sliding down according to the size of the laptop.
[0021] The folding table of the vehicle notebook stand of the present invention for achieving the above purpose comprises an upper table formed into four pieces so as to be foldable by industrial injection molding, a first hinge assembly in the middle, and second hinge assembly parts on both sides.
[0022] The above table top is composed of a pair of inner left and right table tops and a pair of outer left and right table tops.
[0023] The above first hinge assembly is composed of a plurality of fixed axle protrusions formed facing each other in the longitudinal direction at a predetermined interval on the inner left and right upper plates, and a plurality of first joints that connect the opposite fixed axle protrusions to the first joint body through axial coupling.
[0024] The second hinge assembly on both sides above is composed of a plurality of fixed axle protrusions formed facing each other in the longitudinal direction at a certain interval on the inner side of the outer left and right upper plates and the outer side of the inner left and right upper plates, and a second joint that connects the opposed fixed axle protrusions to the second joint body through an axial connection.
[0025] In the present invention, the first hinge assembly part and the second hinge assembly part are configured by axially assembling a pair of connecting axial holes formed through the protrusion bodies of the fixed axial protrusions formed in the inner left and right upper plates and the outer left and right upper plates, and a pair of connecting axial holes formed through the upper and lower sides corresponding to the axial holes in each of the first and second joint bodies, through mutual axial pin coupling.
[0026] In the present invention, a receiving groove is formed on the front surface of the first joint body of the first joint. A cut-out groove is formed on the inner sides of the receiving groove so that the lower sides of a pair of connecting shaft holes formed on the first joint body can be opened, and the cut-out groove is formed so as to face each other. A support piece can be assembled in a state in which it is stored in the receiving groove. The support piece is assembled by opening the cut-out groove and fitting a rotational axis projection protruding from both sides of the support body into the cut-out groove. The support piece has a folded position in which it is stored in the receiving groove, and an unfolded position in which it is opened so as to have a supporting function by rotating downward, for example, 90 degrees (°), around the rotational axis projection.
[0027] Here, a coupling protrusion is formed protrudingly in the receiving groove of the first joint body of the first joint, and a receiving assembly groove is formed in the support piece to receive the coupling protrusion in the folded position and to engage with the coupling protrusion in the unfolded position so that the support piece is supported in the unfolded position. In addition, the support body of the support piece has friction protrusions formed on both sides to support the state in which the support piece is received in the receiving groove, and a gripping protrusion formed on the upper side.
[0028] In the present invention, first stopper protrusions are formed to protrude in opposite directions on the upper and lower sides of the inner left and right upper plates of the upper plate table so that a 180-degree unfolded state is maintained. An axial hole connected to the connecting axial hole of the first joint is formed through the upper and lower sides of each of the first stopper protrusions and is axially connected with an axial pin.
[0029] In the present invention, a second stopper projection and a third stopper projection are formed to protrude in opposite directions on the upper and lower sides of the outer side of the inner left and right upper plates and the inner side of the outer left and right upper plates so that a 180-degree unfolded state is maintained. An axial hole connected to the connecting axial hole of the second joint is formed through the upper and lower sides of each of the second and third stopper projections, and the two are axially coupled with an axial pin. A coupling projection bent at a 90-degree angle is formed on the second stopper projection, and a coupling hole into which the coupling projection can be inserted is formed on the third stopper projection, so that the 180-degree unfolded state is fixed by mutual assembly.
[0030] In the present invention, the outer left and right upper plates are folded in a state where they are exposed on the front surface of the inner left and right upper plates, and can be used in a single-stage folded state.
[0031] In the present invention, the outer left and right upper plates can be used by rotating the inner left and right upper plates around an axis, so that the inner right and left upper plates and the outer left and right upper plates can be used in a two-stage state in which they are spread out 180 degrees.
[0032] According to the present invention, the space limitation of a laptop stand installed in a vehicle can be expanded to the maximum extent possible to provide more convenient laptop work, and convenience is guaranteed by enabling quick installation and removal.
[0033] Furthermore, according to the present invention, the 180-degree unfolded state in one or two stages depending on use is fixed in a horizontal state, thereby providing a table function regardless of the weight of the laptop. For example, if seven support pieces are provided, the stand can be provided in seven stages depending on the laptop, thereby ensuring convenience.
[0034] In addition, according to the present invention, components can be manufactured industrially using synthetic resin materials through injection molding, so that slimmer products can be expected as well as mass-produced, and it becomes possible to provide lightweight products and lower manufacturing costs.
[0035] In addition, according to the present invention, depending on the type of laptop, it can be easily placed and maintained in a placed state without falling down, and it has the advantage of being easy to carry and store by folding it after use.

[0051] Referring to these drawings, it can be stored and carried in a folded state as in Fig. 3, and when necessary, it can be used in a single-stage unfolded state as in Fig. 4, or in a two-stage fully unfolded state as in Figs. 1 and 2.
[0052] Referring to these drawings, the present invention is largely composed of a top plate table (100) composed of four top plates, a first hinge assembly part (200) that connects and folds the four top plates constituting the top plate table (100), and second hinge assembly parts (300) on both sides.
[0053] The above-mentioned table top (100) comprises four upper plates that are formed into foldable sections. The upper plates are industrially manufactured by injection molding. The upper plates formed into four sections include a pair of inner left and right upper plates (110, 120) and a pair of outer left and right upper plates (130, 140).
[0054] The above first hinge assembly (200) is composed of a plurality of fixed axle protrusions (150) formed longitudinally and facing each other at regular intervals on the inner side of the inner left and right upper plates (110, 120), and a plurality of first joints (210) that connect the fixed axle protrusions to the first joint body (220) through axial coupling.
[0055] The second hinge assembly (300) is composed of a plurality of fixed axle protrusions (150) formed longitudinally and facing each other at regular intervals on the inner side of the outer left and right upper plates (130, 140) and the outer side of the inner left and right upper plates (110, 120), and a second joint (310) that connects the fixed axle protrusions to the second joint body (320) through an axial connection.
[0056] As shown in FIGS. 6 and 7, the first hinge assembly (200) in the center is composed of a fixed axle projection (150) formed on the inner left and right upper plates (110, 120) and an axle pin connection of the first joint (210).
[0057] The fixed axle projection (150) formed on the inner left and right upper plates (110, 120) has a projection body (151) and is formed with the same structure in which an axis hole (152) penetrates the upper and lower sides of the projection body (151).
[0058] The first joint (210) is formed with a pair of connecting shaft holes (230) formed through penetration on the upper and lower sides corresponding to the shaft hole (152) in the first joint body (220), and the shaft hole (152) and the connecting shaft hole (230) are assembled by coupling with a shaft pin (P).
[0059] At this time, the first joint (210) is formed with a cut shaft groove (235) facing the inner sides of the receiving groove (240) while the lower side of the connecting shaft hole (230) is openable in a state in which a receiving groove (240) is formed on the front surface of the first joint body (220), and the support piece (260) is assembled in a state in which it is received in the receiving groove (240). The spreading is provided by a 90-degree rotation of the support piece (260).
[0060] The above-mentioned support piece (260) is assembled by opening the above-mentioned cut-out groove (235) and fitting the protruding rotational projections (280) on both sides of the support body (270). By rotating the support body (270) downward 90 degrees around the rotational projections (280) and unfolding it, the bottom of the main body of the notebook can be supported, thereby implementing the support function without sliding.
[0061] Here, a connecting projection (245) is formed to protrude into the receiving groove (240) of the first joint body (220) of the first joint (210). A receiving assembly groove (275) in which the connecting projection (245) can be received is formed in the support piece (260).
[0062] The above storage assembly groove (275) allows the support piece (260) to be folded by receiving the connecting projection (245) when the support piece (260) is received in the storage groove (240). In addition, the storage assembly groove (275) is formed so that when the support piece (260) is unfolded by a 90-degree rotation in the storage groove (240), the lower end of the connecting projection (245) is caught in the storage assembly groove (275) to provide a function of firmly supporting and maintaining the support piece (260) in a state where the support piece (260) is rotated by 90 degrees.
[0063] The position where the above-mentioned support piece (260) is stored in the above-mentioned storage groove (240) is referred to as the folded position, and the position where the support piece (260) is unfolded by a 90-degree rotation with respect to the first joint body (260) and supported by the 90-degree rotation of the support piece (260) by contact between the above-mentioned connecting protrusion (245) and the above-mentioned storage assembly groove (275) and thereby can perform the support function is referred to as the unfolded position.
[0064] In the embodiment of the present invention, the support piece (260) is described as being unfolded by a 90-degree rotation, but is not limited to a 90-degree rotation and may have an appropriate angle at which a laptop or the like can be placed.
[0065] The support body (270) of the above support piece (260) has friction protrusions (276) formed on both sides, and a gripping protrusion (290) protruding and formed on the upper side.
[0066] The above friction protrusion (276) can maintain the folded state of the support body (270) in a fixed state.
[0067] According to an embodiment of the present invention, seven of the supporting pieces (260) can be assembled corresponding to each of the first joints (210). When the driver works on the laptop, depending on the size or support position of the laptop, the driver can hold the grip projection (290) of the supporting body (270) and rotate the supporting piece (260) 90 degrees around the rotational axis projection (280) in the storage groove (240) of the first joint to support the bottom of the laptop body while working. Therefore, there is a convenient advantage in that the work is provided while preventing the laptop from sliding.
[0068] As illustrated in Fig. 8, the second hinge assembly (300) is formed with a structure identical or similar to that of the first hinge assembly (200) except for the structure for assembling the support piece (260) to the first joint (210).
[0069] That is, the outer side of the inner left and right upper plates (110, 120) and the inner side of the outer left and right upper plates (130, 140) are formed with shaft holes (152) penetrating through the upper and lower sides of the protrusion body (151) of the correspondingly formed fixed axle protrusion (150), and a pair of connecting shaft holes (330) equivalent to the shaft holes (152) are formed in the second joint body (320) of the second joint (310) and are axially connected with the shaft pin (P).
[0070] In this specification, the connecting shaft hole (230) formed in the first joint body (220) and the connecting shaft hole (330) formed in the second joint body (320) are formed corresponding to each shaft hole (152) formed in each protrusion body (151) and are connected with shaft pins, so although their arrangements are different, their functions are the same and are therefore referred to by the same name.
[0071] Meanwhile, on the inner side of the inner left and right upper plates (110, 120) that construct the upper plate table (100), first stopper protrusions (111, 121) are formed to protrude in opposite directions on the upper and lower sides so that a 180-degree unfolded state is maintained. An axial hole (152) that is formed to engage with a connecting axial hole (230) formed in the first joint body (220) of the first joint (210) is formed through the upper and lower sides of each of the first stopper protrusions (111, 121) and is axially connected with an axial pin (P).
[0072] It is preferable that the first stopper projection (111, 121) provided on the inner left and right upper plates (110, 120) be formed with a wide thickness so as to maintain a 180-degree flat surface in the unfolded state and to reinforce the strength in the unfolded state.
[0073] In addition, as shown in the enlarged extract of FIG. 8, the second stopper protrusion (112, 122) and the third stopper protrusion (131, 141) are formed in a protruding manner on the upper and lower sides so that the 180-degree unfolded state is maintained on the outer side of the inner left and right upper plates (110, 120) and the inner side of the outer left and right upper plates (130, 140).
[0074] At this time, a shaft hole (152) that fits into the connecting shaft hole (330) formed in the second joint body (320) of the second joint (310) is formed through the upper and lower sides of each of the second stopper protrusion (112, 122) and the third stopper protrusion (131, 141) and is axially connected with an axis pin (P). The second stopper protrusion (112, 122) is formed with a connecting protrusion (113, 123) that is bent, for example, bent by 90 degrees, and a connecting hole (132, 142) into which the connecting protrusion (113, 123) is fitted is formed in the third stopper protrusion (131, 141) of the outer left and right upper plates (130, 140). By assembling the second stopper protrusion (112, 122) and the third stopper protrusion (131, 141), the 180-degree unfolded state is fixed, and maintenance and reinforcement of the solid 180-degree unfolded state are provided.
[0075] According to the present invention, as illustrated in FIG. 9, the outer left and right upper plates (130, 140) are folded in a state in which they are exposed on the front surface of the inner left and right upper plates (110, 120) and can be used in a single-stage folded state.
[0076] In addition, the present invention can be used in a state where the inner left and right upper plates (110, 120) and the outer left and right upper plates (130, 140) are spread out in a two-stage manner by 180 degrees by rotating the outer left and right upper plates (130, 140) around the inner left and right upper plates (110, 120), as shown in FIG. 10.
[0077] The present invention can be used by being installed in an unfolded state on a notebook stand assembled to a vehicle handle as illustrated in FIG. 11, for example, in the state illustrated in FIG. 1, the support piece (260) constituting the first hinge assembly (200) can be unfolded to an unfolded position, and when working on a notebook, the selected support piece (260) can be unfolded according to the size or support position of the notebook, thereby supporting the bottom of the notebook body, thereby providing a convenient advantage in that the notebook is prevented from sliding.
[0078] That is, the present invention can be stored folded as shown in Fig. 3 when portable, and used unfolded as shown in Figs. 1 and 4 when in use.
[0079] While the detailed description of the present invention has described specific embodiments, it should be understood that various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims set forth below but also by equivalents thereof.
