Description

[Detailed Description of the Invention] The present invention relates to ashtrays for chairs used for meetings, lectures, etc.

Since the chairs used for meals and banquets have tables in front of them, ashtrays are placed on the tables and smoking is allowed freely, but in the case of meetings and lectures where only chairs are lined up in the venue, there are no ashtrays. If the event lasts for a long time, participants may not be able to resist the ban and often leave their seats and go out into the hallway, not only making the venue noisy but also being disrespectful to the speaker.

Normally, in the case of such conference chairs, there is usually a space between the cushion body and the back plate, and the present invention is an ashtray that can be attached to such chairs arranged side by side. A metal plate for attaching an ashtray is provided on the back of the backboard, and an ashtray with a handle is provided on this plate so that it can be freely attached to the metal plate, thereby allowing smoking freely at the venue, and providing an ashtray that is easy to clean since it can be attached freely. It is something to do.

To explain the ashtray of the present invention with reference to the attached drawings,
FIG. 1 shows a side view of a chair with an ashtray 1 attached,
FIG. 2 shows the back of the chair, and FIG. 3 shows a plan view of the ashtray 1. FIG. 4 is a longitudinal cross-sectional view of the ashtray 1,
FIG. 5 is a detailed view showing the fitting of the handle 4.

In the figure, A indicates the back of the back of the chair, and a hollowed-out gap is provided in the center of the back of the back, and a T with a wide upper part is formed on the surface of this gap.
A metal plate 5 provided with a letter-shaped fitting groove 6 is attached, while a handle 4 is protruded from one end of the metal ashtray 1, and a horizontal overhang 2 is formed at the tip of the handle 4 and a locking protrusion is provided below. The ashtray 1 thus formed is detachably attached to the back surface A of the back plate of the chair.

The above was about ordinary conference chairs, but
The invention can also be applied to a foldable pipe chair as shown in FIG. A′ in the figure indicates the back plate.

Therefore, when installing, when the overhanging part 2 of the handle 4 of the ashtray 1 is inserted from the wide top of the T-shaped fitting groove 6 of the metal plate 5 and moved below the T-shaped groove 6,
The handle 4 abuts against the lower end 7 of the T-shaped groove 6, and the ashtray 1 is held horizontally and stabilized by the horizontal extension 2 of the handle 4 and the lower locking protrusion 3. Therefore, when removing the ashtray 1, the fitting handle 4 can be removed from the wide part above the T-shaped fitting groove 6 by simply lifting the ashtray 1 upward by performing the reverse operation as described above.

As mentioned above, the present invention has a simple structure because a metal plate is provided on the back of the back of a conference chair, and an ashtray is removably attached to this.
When the ashtray is not needed, it can be removed at all times, and the ashtray is attached only when necessary, so the presence of the ashtray does not get in the way, and by using the ashtray, the ash does not fall on the floor. There's no danger. Furthermore, when the ashtray is attached, the overhanging part of the ashtray handle and the locking protrusion allow the ashtray to be stably locked, so there is no risk of it falling off, and cleaning is easy, making it ideal for meetings and lectures. It can be used practically and conveniently.
