Description

[Detailed description of the invention] [Field of industrial application] This invention relates to the improvement of a table with a shelf that can be folded upright at the center of the top plate, and in particular, a folding table with an improved position of the pillars. Regarding.

[Prior Art] In the case of a table that is folded into an upright position, conventionally, as shown in FIGS. 1 and 2, the ground-contacting side of the pedestal 10 is placed outside the base end position, either directly or via a pedestal 11. It has a structure that extends in the direction.

This is to stabilize the folded posture.

In this case, the base end of the pedestal must be placed closer to the inside of the top plate in order to allow seating on the table from the shorter side of the top plate.

However, if the base end of the pedestal is closer to the inside of the top plate, the distance between the pedestals becomes narrower, the seating space on the long side of the top plate becomes narrower, and the shelf space stretched between the pedestals becomes narrower. I have some regrets.

Furthermore, as seen in the variable-format table reading seat device disclosed in JP-A No. 49-51061, the lower end of the pedestal is curved and extended outward in the longitudinal direction of the top plate, and the lower end thereof is a rod having a caster. Fixed configurations are also known.

With this configuration, it is possible to increase the shelf space by widening the space between the legs, but since the legs hang from two places, one end of the top plate and the other in the center, it is necessary to sit from the short side of the top plate. This is inconvenient as the user must sit with the leg between his or her feet.

[Problem that the invention attempts to solve]

This idea was created as a result of intensive research in view of the above circumstances, and its purpose is to:
It is possible to use table seating from the short side of the top plate, and the seating space on the long side can be set wider (wider frontage), and the space in the longitudinal direction of the shelf can also be set wider accordingly. We offer a folding table with great convenience.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention includes a top plate, a pair of left and right independent pillars supporting the top plate, a shelf member stretched between the pillars, and a top plate positioned at the center of the longitudinal side. a top plate folding device that bends at the top plate and folds it into an upright position, the lower end side of the pedestal is curved outward in the longitudinal direction of the top plate and slightly extends, and the pedestal is perpendicular to the extending direction. In a folding table having a leg stand provided at the tip thereof and a caster fixed to the underside of the leg stand, a) the top plate folding device is configured to connect a connecting portion of the top plate which is divided into left and right sides when folded; A hanging cylinder connected at a position biased toward one end of the body, a slide member fitted into the hanging cylinder, and an upper end pivotally attached to the top plate side at a spaced apart position sandwiching the connecting part of the top plate. and a pair of left and right stays whose lower ends are pivoted to the lower end of the slide member, b. The pedestal is located at the center of the top plate in the short side direction of the top plate and between the center position of the top plate folding device. A technical measure has been taken in which the base of the pedestal is located near the hanging position of the outer end of the longitudinal side of the top plate in the longitudinal direction of the top plate. There is.

[Effect]

In the direction of the shorter side of the top plate, the space on one side of the pedestal partitioned by the pedestal is wide open, so the seated person can walk from the short side of the top plate without being obstructed by the pedestal. can be entered.

Furthermore, in the longitudinal direction of the top plate, the pillars are located closer to the outer ends of the long sides, so there is also a large space on the long side of the top plate, making it possible to increase the length (area) of the shelf provided under the top plate. .

〔Example〕

The foldable table according to this invention will be explained below with reference to the drawings.

The folding table 1 shown in FIGS. 3 to 5 is
A top plate 2 and a pair of independent pillars 10 that support the top plate
, a shelf member 4 stretched between the pillars, and a top plate folding device 5 that folds the top plate 2 and shelf member 4 into two in an upright position.
It is made up of.

That is, the top plate 2 is divided into two parts of the same shape and size,
At the same time, the top plate support frame 3 and the shelf member 4 disposed below it in parallel and spaced apart positions are also divided into two pieces of the same shape and size, with opposing ends attached to pins 21 and 2.
It has a bilaterally symmetrical structure in which the two parts are connected in a flexible manner.

The top plate support frame 3 having the above structure is rotatably connected and supported on the outer end side by a pin 23 to the upper end of the pedestal 10.

Further, a shelf support frame 41 is fixed to the middle part of the pedestal 10, and an end of the shelf member 4 is rotatably pivoted to the shelf support frame 41 by a pin 24.

Next, in the case of the illustrated example, the top plate folding device 5 includes a hanging cylinder 51 whose upper end side is connected via a pin 21 to a position biased toward one end of the connecting portion of the pair of left and right top plate support frames 3; A slide member 52 fitted into the cylinder 51 and the upper end of the slide member 52 are rotatably connected to each frame at a spaced apart position sandwiching the connecting portion 21 of the frame, and a lower end of the slide member 52 is rotatably connected to the lower end of the slide member 52. A pair of connected left and right stays 5
3, 53, and the hanging cylinder 5 at the horizontal deployment position of the top plate 2.
1 and a locking means 8 for automatically locking the slide member 52.

Here, as shown in FIG.
A lock pin 82 is provided in the frame and is held in a position where it can be freely inserted into and removed from the lock hole 81 when the frame is in a horizontally deployed position, and is always biased in the direction of insertion into the lock hole, and a lock pin 82 is provided in the vicinity of the lock hole on the side of the hanging cylinder. The shutter member 83 is provided to block a gap between the two when the lock pin is pulled out from the lock hole 81, and is displaced from the blocking position of the lock hole 81 to the blocking release position by the lock pin 82 when the frame is expanded.

Next, the shelf folding device 7 that folds the shelf member 4 together with the top plate 2 is configured to fold the shelf while maintaining the distance between the connecting portion 22 of the shelf member 4 and the connecting portion 21 of the top plate support frame even when folding. One connecting portion 22 of the member 4 is pivotally connected to the hanging cylinder side, and the other connecting portion 22' is connected to the connecting portion 21' of the top plate support frame via an auxiliary rod 71.
It has a structure in which it is connected and pivoted.

In the above configuration, the lower end of the pedestal 10 is slightly curved outward in the longitudinal direction of the top plate, and a pedestal 11 is provided at the lower end of the pedestal 10 perpendicular to the extending direction. It is being

Here, the pillar 10 is located between the center position of the top plate 2 in the short side direction and the mounting position of the top plate folding device 5, and is also located in the long side direction of the top plate 2. In this case, the pedestal 11 of the pedestal 10 is formed to be located approximately at the same position as the hanging position of the outer end of the longitudinal side of the top plate 2, or slightly inward.

In addition, the above-mentioned leg stand 11 has casters 1 on the lower side of both ends.
It consists of a rod having 2 and 12 rods and is fixed integrally with the lower end of the pillar 10.

Therefore, in this case, the pedestal 10 is vertical and the pedestal 1
1 is formed into a U-shape or a V-shape and is easier to manufacture or install than a configuration in which the two are connected, and since it is linear, it does not get in the way when sitting on the table.

The top plate support frame 3 and the shelf member 4 are pivotally mounted between the pair of left and right independent pillars 10, 10 that face each other in this manner.

Therefore, the folding table 1 has a top plate folding device 5.
The folding posture and the top plate 2 in which the center of the top plate 2 rises and is folded in half into an upright shape by the operation of the shelf folding device 7
It can be displaced to a deployed position in which it is horizontal, and is supported by the pillars 10.

Here, the pedestals 10 are arranged between the central position of the top plate 2 in the short side direction and the top plate folding device 5, so that it stably supports the top plate 2 in the unfolded or folded position. be able to.

[Effect of idea]

In the present invention, each pedestal is arranged to be biased to one side from the center position in the short side direction of the top plate, so that the wide space partitioned by the pedestal can be used as a seating space. can.

Since the legs and footrests do not get in the way when sitting on the short side of the top, the legs are placed as far as possible toward the outer end of the long side of the top. A proximal end can be disposed.

Furthermore, since the legs are arranged near the hanging position of the outer end of the long side of the top plate, the spacing between the legs can be set wide, increasing the seating space of the table. .

Furthermore, since the longitudinal sides of the shelf members stretched between the pillars are also set longer, the usable space of the shelf becomes wider, which is advantageous.
