Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for attaching a memo stand in a folding chair.

[Conventional technology]

Conventionally, a folding seat was constructed by connecting a bent flat part at the upper end of the pipe rear leg to the middle of the upper part of the pipe front leg, and attaching the seat body between both legs in a bendable manner. Some chairs have a structure that allows you to attach a memo stand, but there are none that allow you to easily remove the memo stand.
There has never been a single folding chair that allows you to easily attach and use a memo stand and remove it for use.

[Problem that the invention attempts to solve]

The present invention is such that a single folding chair can be used with a memo stand attached to it, or it can be easily removed and used as a chair without a memo stand, and the memo stand can be easily attached and removed. In addition, the present invention provides a simple structure that can be stably supported in an attached state, and is easy to manufacture, so that it can be suitably implemented.

[Means for solving problems]

Therefore, in the present invention, a semi-cylindrical front mounting bracket that can be fitted to the front side of the front leg and opens the rear part,
A rear mounting pipe that has a groove in the vertical direction on its circumference that can be fitted into the flat part of the upper end of the rear leg, and can be fitted into the rear leg.
They are connected integrally with each other at a predetermined distance from each other at a predetermined distance from each other, and have a support rod extending upwardly for supporting the memo stand.

[Effect]

With this configuration, the rear mounting pipe is fitted into the rear leg by fitting the split groove in the flat part, and the front mounting bracket is fitted to the front leg that is opened and deployed at an angle to the rear leg to prevent rattling. The memo stand can be mounted stably and firmly so that it does not come off, and can be easily removed by reverse operation.

〔Example〕

Next, the embodiment shown in the drawings will be described.

B shows the entire folding chair, with a backrest 8 straddled between the upper parts of the front pipe legs 2, 2 on both sides, and the upper end of the back legs 1, 1 made of pipes on both sides with the front legs as seen from the side. The flat portions 1a are each pressed and formed so as to be bent, and both flat portions 1a are
Insert the tips of the pins 9, 9 into the upper parts of the front legs 2, 2.
The front leg 2 and the rear leg 1 are rotatably attached to each other by insertion, and at positions below the pin 9 of the front leg 2 and the rear leg 1, there is a support shaft 11 for pivotally supporting the seat body 3 and the support rod 10 for supporting the seat body. 12 are respectively inserted, and the rear side of the seat body 3 and the front end of the support rod 10 are connected freely to rotate, and the seat body 3 is also installed so that it can be folded, so that the structure is similar to the conventional structure. .

Reference numeral 6 denotes a rear mounting pipe. On the front surface of the pipe 6 which can be fitted into the rear leg 1, split grooves 5 which can be fitted into the flat part 1a are formed across both ends. The front mounting bracket 4, which is fixed to the rear part of the connecting plate 13 and the front part of the connecting plate 13 is fixed to the outer surface, is tilted in a crosswise direction at a predetermined interval with respect to the rear mounting pipe 6, and the front leg is extended. The support rod 7 made of a pipe is formed into a semi-cylindrical shape with its rear open so that it can be fitted onto the front side of the connecting plate 13, and its lower end is fixed to the intermediate outer surface of the connecting plate 13. It is formed to extend forward, and a memo stand A is attached to its upper part 7a so that it can be fixed in a horizontal position and rotated into an upright position, as in the conventional type.

Therefore, when installing memo stand A, the seventh
As shown in the figure, the chair B is folded so that the seat body 3 is folded and the front legs 2 and the rear legs 1 are close to each other. As shown in Figure 10, align the rear mounting pipe 6 and insert the split groove 5 into the flat part 1.
a, lower it as shown by arrow A, and fit the rear mounting pipe 6 into the rear leg 1. Fit the pipe 6 into the rear leg 1 as shown in FIG. In this state, when the chair is unfolded as shown in FIG. 3, the front mounting bracket 4 is fitted as shown in FIG. 1 so as to lean against the front side of the front legs 2 facing forward. , as shown in FIGS. 4 and 5, the memo stand A can be stably attached so that it will not come off.

Further, the memo stand A can be removed from the chair B by the reverse operation.

12 and 13 show other embodiments,
The structure is substantially the same as that of the previous embodiment, but the front side of the upper half of the rear mounting pipe 6 is made semicircular and the notch 6a is formed.
In this case, even when the chair B is unfolded, the rear mounting pipe 6 can be inserted into the rear leg 1 from above.

FIG. 14 shows yet another embodiment, in which the length L of the rear attachment pipe 6 is extremely shortened, so that it can be attached and detached even when the chair B is unfolded, as described above.

FIG. 15 and FIG. 16 each show another embodiment in which the front mounting bracket 4 and the rear mounting pipe are connected by the bent lower part 7b of the support rod 7 instead of being connected by the connecting plate 13 as in the previous embodiment. 6 can be connected together.

[Effect of idea]

In this way, the present invention fits the split groove 5 into the flat part 1a, fits the rear mounting pipe 6 into the rear leg 1, and attaches the front mounting bracket to the front leg 2 which is opened and deployed at an angle to the rear leg 1. By fitting 4, you can easily attach memo stand A, and by reversing the operation, you can easily remove it and attach memo stand A whenever necessary. , the memo stand A can be stably supported without coming off or wobbling because it is firmly attached, and has a simple structure that is easy to manufacture and can be suitably implemented.
