Description

Folding table with easy assembly structure {Folding table with easy assembly structure}

The present invention relates to a folding table that can be used to fold or store and transport a top plate in various places such as a lecture room or a conference room, and more specifically, a folding table composed of a bridge support, a top plate, and a locking and unlocking configuration for the top plate. With respect to the improved assembly structure and complementary configuration of the upper plate flow prevention means and the upper plate deployment means, the present invention relates to a prefabricated folding table that further improves assembly efficiency and operation convenience for the upper plate.

In general, portable tables with casters at the bottom of four legs are widely used in classrooms, offices, conference rooms, cafeterias, etc. to facilitate the adjustment of the number and location of seats.

When the seat is arranged using the movable table, the table can be easily moved by the caster, and a caster with a brake is used to prevent the caster from rolling after the seat is disposed.

Then, in addition to the movable table as described above, a folding table in which the top plate of the table is rotated in a vertical or horizontal state is mainly used. In the folding table, the hinged fixed top plate from the lower support is vertical or As it is rotated in a horizontal state, the top plate in a horizontal state is locked by a fixing means, and thus performs the same operation and purpose as a conventional table through the top plate in a horizontal state. When it is necessary to place it, it is made to be able to stand the upper plate in a vertical direction so as to occupy the minimum occupied space.

That is, the folding table as described above is composed of a pillar and a supporting member, and a top plate rotating from the tip of the pillar, as shown in Patent No. 0361156, and installed to operate in the up and down directions through the pillar and the supporting members. It is for a folding table that allows the working link to be close to one of the moving wheels, and a separate stopper is installed together, so that when the top plate is unfolded and used, the pillars and the supporting members are kept steadily without touching or shaking. Mobile bearings have been created and registered.

In addition, as in the registered patent No. 0317721, the pillars and the supporting members are used as a support so that the operating link and the lifting members cooperate with each other to operate the stoppers installed on the lifting members toward the bottom surface, and when the first board is unfolded and used It maintains the stop state reliably to promote stability, and reduces the user's trouble and hassle when operating to move or stop the second, thereby improving convenience, and avoiding excessive manipulation, greatly extending the service life and reliability The movable support of the folding table, which improves, has been devised and registered.

Subsequently, as in the registered patent No. 0652529, the number of parts is small, the structure is simple, and the cost can be reduced and the assembly productivity can be improved, but the table can be fixed so that it does not move. The caster assembly and the folding table using the caster assembly have been created and registered so that the height of the folding table can be adjusted more conveniently without separate paper or wood.

However, in the case of the existing folding table or folding table, a pair of support angles or lower supports are made to be connected and fixed by welding or the like in the factory manufacturing process, and the top and top supports are mutually different depending on manufacturing characteristics or structural characteristics. It is made in a fixed state, and the hinge coupling part for connecting these support angles and the top plate to each other, and the rotation locking means of the top plate, etc. are all made in a fixed condition through assembly or welding. There is a problem that occurs.

That is, in the existing folding table, the size of the leg member is very large in the lower support, which is made of pillars in all directions or in the form of welding by bending pipes or cross supports, and in addition to these leg members, the upper plate locking means and the upper plate hinge coupling means are considerable. Because it occupies the volume, the storage area and loading area are very large, even when the top plate is placed vertically, resulting in excessively high logistics costs.

In addition, even when the folding table or the folding table is not used for a long time, the individual components cannot be disassembled directly by the consumer, so the inconvenience of storage is very large, and the mutual locking means between the lower support and the top plate is dependent on the weight of the entire table. Compared to the poor, it is the situation that the shaking of the top plate is continuously pointed out in the process of use, and if excessive weight is put on the top plate or an excessive load due to the user's weight is applied, damage or deformation of the locking means is not possible. It has a problem that occurs.

Accordingly, the applicant of the present invention connects and secures the ends of a pair of mutually spaced leg supports to each other through a crossbar, as shown in 2019 Patent Application No. 000000, but the crossbar is formed with a locking fastener coupled to the bottom of the separately provided top plate. On the upper plate support, as the shaft and the release lever and the release lever corresponding to the locking fixture are axially coupled, both the leg support, the top plate, and the locking and unlocking means can be easily assembled or disassembled, as well as the locking fixture and the rotating mechanism. And the locking and releasing means of the top plate by the release lever has been devised a prefabricated folding table with improved locking and releasing means, which allows the top plate to be quickly and efficiently opened and fixed or moved.

However, in the above-described prefabricated folding table, the coupling structure between the top plate support and the top plate is not easy, so the height or spacing of the top plate support spaced apart in a pair does not match, and as a result, the assembly completeness is poor. If it is not fixed to the correct position on the bottom of the top plate, it is impossible to assemble the table or the rotation operation of the top plate cannot be smoothly performed.

In addition, in the case of the top plate of the prefabricated folding table, if the user wants to rotate from the horizontal state to the vertical direction, the user must lift the top plate using the artificial force of the user or operator. It is a hassle to use both hands by rotating the lever and lifting the top plate in the unlocked state with the other hand.

In addition, the upper plate rotated in a horizontal state by descending, and in the rotation lock state with respect to the upper plate, the upper plate has a fine rotation clearance angle around the hinge axis, which is inevitable due to errors in the production process and assembly process. As the clearance occurs, the upper plate has a shake due to the rotation clearance angle or the clearance, which is very inconvenient for use, and in the case of an elongated table, the load is concentrated in the central portion of the upper plate in the form of a single plate and both sides It has a closed end in which the center of the upper plate corresponding to the spaced apart upper plate support is concavely bent or deformed.

Republic of Korea Registered Patent 10-0361156 (Registered on November 1, 2002) Republic of Korea Registered Patent 10-0893947 (Registration on December 4, 2001) Republic of Korea Registered Patent 10-0652529 (Registered on November 24, 2006)

The present invention is to improve the problems as described above, the top plate support of the prefabricated folding table is composed of a square tube to form a fixed stopper on both ends of the top plate support, and a compression spring is attached to a hinge pin to which a locking fixture is coupled. Insertion is formed, the upper side of the locking fastener is coupled to form a clearance prevention hole, as the hinge to form a hinged rotation bracket for fixing the cover plate to the fixed closing hole,

According to the present invention, it is possible to quickly and efficiently fix the top plate support to the top plate by using a fixed closing tool, thereby improving assembly, and the rotating bracket can be directly connected and fixed to the fixed closing tool, thereby enabling efficient assembly of the blind plate. This is because the top plate can be easily rotated in a vertical direction with one hand, which greatly improves the convenience of use. By removing the play against the top plate in a horizontal state, it is possible to prevent the top plate from shaking in the process of use. Thereby, the center of the upper plate can be prevented from being bent or deformed to the lower side, so that the service life is greatly extended.

Prefabricated folding table according to the present invention, as shown in the figure, a pair of legs spaced apart from each other, the upper plate 30 located on the support 10, 10 'is hinged on the support 10, 10' It is configured to be rotated in the vertical direction or the horizontal direction, and the leg supports 10 and 10 'may be formed by combining bent pipes of different lengths or by combining a vertical support and a horizontal support. It may be made of, and the top plate 30 may be manufactured in a flat shape using wood or synthetic resin.

Subsequently, in the case of the leg supports 10 and 10 ', the front ends are connected and fixed to each other by a separate crossbar 20, and a pair of locking fasteners separately provided at the top of the crossbar 20 (50) (50 ') are fixed to be spaced apart from each other.

In addition, a pair of upper plate supports 40 and 40 'spaced apart from both sides are coupled to the bottom surface of the upper plate 30, and the above-mentioned hanging fasteners are provided below the upper plate supports 40 and 40'. (50) The other end of the (50 ') is axially coupled to each other by a separate hinge shaft 41, and the upper side of the upper plate support 40, 40' is provided with a separate rotation counter 60, 60 ' ) Is coupled so as to be rotatable from the top support (40) (40 '), the rotation stopper (60) (60') is a separate release lever located on the side of the top support (40, 40 ') (70) (70 ') as being axially coupled, by the rotation of the release lever (70) (70') is that the rotation mechanism (60, 60 ') can be rotated at the same time.

Therefore, as shown in FIG. 9, the upper support using the hinge shaft 41 with respect to the fasteners 50 and 50 'coupled to the crossbar 20 for connecting and fixing the leg supports 10 and 10' 40) The upper plate 30 coupled to the upper plate support 40 and 40 'as the 40' is combined and formed can be rotated in the vertical or horizontal direction using the hinge shaft 41 as a rotation axis. As it is, when rotating the top plate 30 downward by applying an artificial force to rotate the top plate 30 in the vertical state in the horizontal direction, a rotation system coupled to the top plate support 40, 40 'of the bottom surface of the top plate 30 The earth (60) (60 ') is rotated downward toward the jamming fixture (50) (50'), and the rotating earth (60) (60 ') rotates at the moment causing interference with the jamming fixture (50) (50') The possible rotational rotation zones 60 and 60 'are reverse rotation due to the slip action of each other.

Subsequently, due to the continuous downward pressing force on the top plate 30 by the user, the ends of the rotating stoppers 60 and 60 'are disengaged from the ends of the locking fixtures 50 and 50', and at the same time, the rotating stoppers 60 and 60 The end of ') is in a locked state to prevent the top plate 30 from being rotated in the upward direction due to the interlocking fixation as the fastening position is fast downward to the lower side of the locking fixtures 50 and 50'.

Therefore, it is possible to fix and lock the horizontal plate with respect to the upper plate 30 by simply rotating and pressing the vertical top plate 30 in the horizontal direction, so that the convenience in use is very excellent.

Conversely, in the case where the top plate 30 is to be vertically erected in the horizontal locking state as described above, when the release levers 70 and 70 'located on both sides of the bottom surface of the top plate 30 are rotated, at the same time, the rotation stopper 60 ) (60 ') is rotated together, and as the rotational stops (60) (60') are rotated in the reverse direction, the upper plate (30) in the vertical direction is completely separated from the locking fixture (50) (50 '). This will lead to a state in which rotation is possible, and the user can easily create a vertical state by lifting the top plate 30.

With respect to the prefabricated folding table having such a structure and operating relationship, the present invention can provide a more advanced prefabricated folding table by applying complementary means for fastening structure and operation between components.

That is, a separate compression spring 42 is inserted into the hinge shaft 41 for axially coupling the locking fixtures 50 and 50 'to the upper plate support 40 and 40' to form the compression spring ( As each end portion of the 42) is configured to be elastically supported on the locking fixtures 50, 50 'and the top plate supports 40, 40', when the top plate 30 is rotated in the horizontal direction in the vertical state, the When the compression spring 42 is compressed and the rotation lock state of the horizontal top plate 30 is released, the upper plate 30 is automatically vertical due to the elastic force of the compression spring 42. It is configured to rotate in the direction.

Accordingly, after the top plate 30 in a vertical state is rotated in a horizontal direction with one hand to make a lock state, the release lever 70, 70 'is also rotated with one hand to lock the top plate 30 in a locked state. When the fixing means is released, the upper plate 30 is automatically rotated in the vertical direction due to the elastic force caused by the compression spring 42. Thus, unlike the conventional method, the horizontal plate or vertical direction of the upper plate 30 is used using one hand. It is possible to realize the rotation and locking state.

In particular, the upper plate support (40, 40 ') is used to cut a square tube, the upper plate support (40, 40') of the cut square tube is inclined cutting portion (43) (45) at both ends 43 ') to form a separate fastener 80, 80' with respect to the ends of the upper plate supports 40, 40 '.

Here, the fixed closing fixture (80) (80 ') of the upper plate support (40, 40') is inserted into the fixed end by the interference fit into the inner end of the upper plate support (81) is formed on one side and the other side Is an inclined groove portion 83 having a fastening hole 82 and 82 'formed through the bottom surface of the upper plate 30 is formed, and the outer body of the inclined groove portion 83 is the upper plate support 40 ) (40 ') When the fitting portion 81 is inserted into the upper plate support 40 (40') as it is configured in the same size and shape as the outer periphery of the body 40, the inclined groove 83 is the upper plate support 40, ( 40 '), which acts as a continuous finish for the ends.

Therefore, the top plate support 40, 40 '(40') on the bottom surface of the top plate 30 in a state of firmly inserting and fixing fasteners 80, 80 'on both ends of the top plate support 40, 40' After being in close contact, it is necessary to securely fix the bolt to the top plate 30 through the fastening holes 82 and 82 'formed in the fixing closing holes 80 and 80' as shown in FIG.

At this time, the bottom surface of the top plate 30 is to be able to work in advance a bolt hole for a fixed position of the top plate support 40, 40 ', the top plate through the bolt hole of the bottom plate formed through post-work It will be possible to further improve the assembly and completeness of the table by keeping the fixed position of the support 40 (40 ') constant.

In addition, the upper portion of the locking fixture (50) (50 ') fixed to the upper surface of the crossbar (20) for connecting and fixing the leg support (10, 10') is provided with a separate clearance prevention device as shown in FIG. 52) as a screw coupling, the clearance hole (50) (50 ') is formed in the vertical direction on the upper surface of the screw hole 51, the clearance hole 52 is screwed into the clearance hole ( 52) is that the tip can be lifted according to the direction of rotation.

Therefore, after the top plate 30 is rotated in the horizontal direction, a locking state of the top plate is made by engaging engagement between the fasteners 50, 50 'and the rotational stops 60, 60', and then the bottom surface of the top plate 30 Or, due to the clearance between the inner surface of the upper support (40, 40 ') and the upper surface of the locking fixture (50, 50'), the upper plate (30) will be shaken in the rotational direction to some extent. Since the shaking of the top plate 30 will act as a factor that interferes with the user's concentration, when the shaking of the top plate 30 occurs as described above, as the rotation of the clearance preventing device 52 is raised, FIG. 7 As shown in the figure of the top plate 30 is locked in the horizontal direction, the tip of the play-off prevention device 52 is supported in contact with the inside of the top plate support 40, 40 ', so as to rotate in the rotation direction with respect to the top plate 30. The flow of does not occur at all.

Subsequently, in the case of the fixed closing fixtures 80 and 80 ', which are coupled to both ends of the upper support 40, 40', the rotating brackets provided separately for the fixed fixings 80 and 80 'on one side ( By combining 90), the separate cover plate 94 can be easily mounted, as well as configured to be able to efficiently rotate the cover plate 94.

That is, as shown in FIG. 8, in the case of the fixed closing tool 80, 80 'coupled to the lower end of the upper plate support 40, 40', the hinge hole 84 is penetrated in the transverse direction in the inclined groove portion 83. The formed bracket connecting portion 85 is protruded, and the bracket connecting portion 85 is hinged to each other by using a separate shaft pin 91 by combining the rotating bracket 90 with the hinge coupling portion 92 formed at the tip. You can do it.

In addition, the one side of the rotating bracket 90 is formed with an enclosing portion 93 for adhering the cover plate 94, and a plurality of coupling holes are provided in the entirety of the rotating bracket 90 corresponding to the enclosing portion 93. (95) (95 ') is formed through at regular intervals.

Therefore, a pair of spaced upper plate supports 40 as shown in FIG. 9 are bolted to the above-mentioned cover plate 94 using the above-mentioned recess portion 93 and the coupling hole 95, 95 '. It is possible to easily mount and fix the elongated panel-shaped cover plate 94 by using 40 ', which is mounted on the lower portion of the top plate 30 as shown in FIG. 10, so that the top plate 30 is in a vertical state. In this case, the blanking plate 94 may also be rotated to face the vertical direction, and when the top plate 30 is rotated in the horizontal direction for use of the table, the blanking plate 94 as shown in FIG. ) Can be used for the purpose of protecting the lower part of the user wearing the skirt by rotating in the vertical direction.

Particularly, it is more efficient because it is not fixedly installed as a separate component on the bottom surface of the top plate 30 as in the prior art, but is combined and installed using the top plate supports 40, 40 'and fixing fixtures 80, 80'. , Since the top plate supports 40 and 40 'having a fixed fixed position are combined, the cover plate 94 can also be quickly and easily fixed at a fixed position, so assembly convenience and efficiency are very excellent.

In addition, in the present invention, a pair of leg supports 10 and 10 'is formed by combining a separate cushion support 100 on the upper surface of the crossbar 20 for connecting and fixing the upper portion of the crossbar 20. After forming at least one or more screw holes 21 in the cushion bar 100 after placing the cushion support 100 having the same or a slightly larger height between the upper surface of the crossbar 20 and the bottom surface of the upper plate 30, the cushion support ( 100) is made by fixing the cushion support 100 to at least one of the bolts securely through the fixing hole 101 formed vertically through.

Accordingly, when the top plate 30 is rotated in the horizontal direction to make the lock state, the cushion support body 100 supports the bottom surface of the top plate, and the top plate corresponds between the top plates 40 and 40 '.
