The upper plate is prevented from shaking and nodding to prevent unnecessary noise, improve learning effects, eliminate disturbance in concentration, and minimize friction or wear by interference to extend the service life of the foldable table to improve economic efficiency.

Description

Vertical folding type folding table with top plate floating prevention structure {Folding table}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding table in which a top plate can be opened or folded in a lecture room or an auditorium. More particularly, the top plate in a horizontally extended state is prevented from wobbling due to clearances and gaps in a top plate locking means, The present invention relates to a vertical holding type folding table to which a top plate floating preventing structure for enabling more stable use of a table is applied.

Generally, in a conference room, a lecture room, or a restaurant, a movable table having a caster at the bottom of four legs is widely used so that the number and position of seats can be easily adjusted.

The table can be easily moved by a caster when the seat is arranged using the movable table, and a caster provided with a brake is used to prevent the caster from rolling after the seating of the seat is completed.

The conventional brake type casters include a caster frame coupled to the lower end of the bridge so as to be horizontally rotatable, a wheel coupled to both sides of the wheel frame so as to be vertically rotatable, A brake lever for releasing the brake, and the like.

A folding type table in which the upper plate of the table is rotated vertically or horizontally is mainly used in addition to the movable table as described above, The upper plate is rotated in the horizontal state and the upper plate in the horizontal state is locked by the fixing means. Therefore, the upper plate in the horizontal state needs to perform the same action and purpose as the existing table, The upper plate can be vertically oriented so as to occupy only a small occupied space.

That is, the folding type table as described above is constructed by a column and a support member and an upper plate that rotates from the tip of the column, and is installed so as to pass through the column and the support members and to move in the upward and downward directions as shown in Japanese Patent No. 0361156 And the stopper is provided with a separate stopper so that the pillar and the supporting member can be surely held in a stationary state without being tangled or wobbled when the upper plate is opened and used. Moving bases have been discovered and registered.

In addition, as disclosed in Japanese Patent No. 0317721, the operating link and the elevating members cooperate with each other using a column and supporting members as a supporting member, so that a stopper installed on the elevating member is operated toward the bottom surface. When the first board is unfolded Thirdly, it is possible to improve the convenience by reducing the labor and hassle of the user when operating to move or stop the second movement. Thirdly, it is possible to extend the service life remarkably by avoiding unreasonable operation, The movement support of the folding table which is provided for the improvement of the folding table has been registered and registered.

Then, as in Patent No. 0652529, it is possible to reduce the number of parts, simplify the structure, reduce the cost and improve the productivity of the assembly, and fix the table so as not to move. The table is not easily tilted, A caster assembly and a folding table using the caster assembly have been developed and registered so that the height of the caster assembly can be adjusted by itself without being fixed by separate bells or trees.

However, in the folding type table as described above, when the upper plate hinged from the front end of the vertical column or the supporting angle is rotated in a horizontal state and the upper plate is locked by the upper plate locking device, the upper plate wobbles or nods, It is a problem that disturbs concentration and of course noise.

That is, in the folding type table, the latching pin is formed to protrude laterally from the upper plate fixing body fixed to the lower side of the upper plate, The latching lever having a groove is fixed so as to be rotatable. When the upper plate rotates in the horizontal direction, the latching pin is inserted into the latching groove of the latching lever, thereby locking the upper plate.

In this case, since the engaging lever is fixed in a rotatable state, it needs a fastening clearance with the rotating shaft, and has clearances and tolerances for mutual engagement and disengagement between the engaging grooves in the engaging lever and the engaging pins. And the tolerance and tolerance shown in the rotary shaft of the upper plate itself. Therefore, the upper plate continues to be wobbled and nodded even in the locked state due to the accumulation of the fit tolerance and the tolerance applied at various portions thereof will be.

Such swinging and nodding not only significantly impedes the user's concentration in the process of using the top plate but also inconvenience to handwriting and memoing. In addition, due to unnecessary mutual interference in the process of shaking and nodding the top plate There is a case in which the user himself or herself may be disturbed by the noise.

FIG. 1 is an overall perspective view of a vertical column type folding type table to which a top plate flow prevention structure according to the present invention is applied, and FIG. 2 is a side view of a vertical column type folding type table to which a top plate flow prevention structure according to the present invention is applied.

As shown in the drawing, the folding type table according to the present invention includes a pair of upper plate supporting means formed by vertical columns 100 coupled to the center of the upper side of the horizontal supports 110, And a caster 111 '111' for moving the folding type table is disposed on the lower side of the horizontal support table 110. The upper and lower tables 130 and 130 ' ) Is mounted.

A support piece 120 for axially coupling the upper plate 130 is fixedly formed on an inner surface of each of the vertical columns 100. The upper plate 130 is spaced apart from the bottom of the upper plate 130 The upper plate 130 and the upper plate support 140 are coupled to the support plate 120 by the side portions of the upper plate support plate 140 being axially coupled to the support plate 120. [ (Not shown).

A hook 150 is hinged on the inner surface of the vertical column 100 so as not to interfere with the support 120. The hook 150 is provided with a hook- And the engaging pin 141 protruding from the side surface of the upper plate supporting table 140 is inserted and fixed in the engaging groove 151 by rotation.

A separate shelf 112 is coupled between the pair of vertical columns 100 spaced from each other as described above so as to be rotatable from the vertical column 100 in a rotatable manner. The shelf 112 is rotated together with the rotation of the upper plate 130 so that the shelf 112 can be folded or unfolded in the vertical or horizontal direction, It can be.

A separate operation rod 160 is inserted into the vertical column 100. An operation protrusion 161 protruding from the inner side of the vertical column 100 is formed at an upper portion of the operation rod 160, The operating protrusion 161 is interfered with the draw openings 114 formed in the both side shaft coupling portions of the electric shelf 112 so that the draw openings 114 are opened simultaneously with the rotation of the shelf 112 The operating rod 161 is lifted or lowered while rotating so that the operating rod 160 can be interlocked with the upper and lower portions.

One end of the seesaw member 170 inserted from the lower side of the horizontal support member 110 is coupled to the lower end of the operation rod 160. The seesaw member 170 has a central portion, And a lower end of the operating rod 160 is coupled with a restoring spring 162 inserted into one end of the seeside member 170. The lower end of the seesaw member 170 is connected to the lower end of the seesaw member 170 And the stopper 180 is fixedly coupled to the bottom surface.

Therefore, when the user rotates the upper plate 130, which is erected vertically, the shelf 112 rotates simultaneously with the upper plate 130, and when the shelf 112 rotates, The stopper 180 on the other side of the seesaw member 170 starts to descend as the operation rod 160 rises.

When the upper plate 130 reaches the horizontal position, the latching pins 141 protruding from the upper plate support 140 under the upper plate 130 are inserted into the latching grooves 151 of the latching lever 150, The stopper 180 on the other side of the seesaw member 170 can be prevented from being rotated by the operation rod 160 lifted upward by the pulling mouth 114, A state in which the bottom surface is strongly pressed is created.

In this case, a separate finishing cover 300 is coupled to the upper part of the vertical column 100, and a fitting hole 301 for inserting the screw thread 210 is formed in the finishing cover 300, As shown in FIG.

The support plate 211 is fixed to the inner surface of the vertical column 100 by means of welding or the like and the screwed portion 212 formed on the support plate 211 is fixed to the inner surface of the vertical column 100 by a rigid screw- And a female screw portion having a predetermined height for the sake of convenience.

The upper plate 130 is rotated in the horizontal direction from the vertical direction so that the latching pins 141 of the upper plate support table 140 are engaged with the latching grooves 151 of the latching lever 150, When the horizontal state is established, the operator or the user rotates the receiving member 200 and the screw rod 210 to set the receiving member 200 so that the bottom surface of the upper plate 130 can be strongly pressed do.

The supporting member 200 made of a resilient material is lifted together with the screw rod 210 so that the supporting member 200 moves from the screw rod 210 to the bottom surface of the supporting member 200 Since the upper plate 130 is continuously pushed up through the entire upper surface of the upper plate 130, the upper plate 130 can eliminate or minimize the allowable tolerance and gap flow acting as a factor of wobbling, The nodding or nodding of the user can be prevented.

When the latching lever 150 is rotated so that the latching pin 141 of the upper plate support table 140 is released from the latching groove 151, the upper plate 130 is returned by a return spring When the upper plate 130 is rotated in the horizontal direction to use the upper plate 130 again, the supporting member 200 is maintained in a state where the height is already set So that it is possible to prevent the upper plate 130 from being shaken or nudged in a horizontal state without a separate adjustment operation.

Accordingly, the upper cover 300 is closed by the upper cover 300, and the top plate 100, which is nodded due to the tolerance in the assembly process through the supporting member 200, 130 can be eliminated.

Particularly, the upper plate 130 is subjected to the upward pressing force of the sustaining member 200, so that the upper plate 130 is deformed due to a tolerance and a clearance that can inevitably occur at the coupling portion or the locking portion of the upper plate 130, So that the user can use the folding table in a more comfortable and quiet state.
