Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a safety lamp in which a lit candle is housed inside a firebox that can be opened and closed, and can be kept safely without being exposed.

(Prior Art) Traditionally, candles used in Buddhist altars and the like are used by standing candles in candlesticks. When the candle burns out, the remaining oil and fat (wax) adheres from the saucer to the vicinity of the candlestick. Naturally, if it is used in that state, the amount of wax deposited will increase, resulting in a problem.

On the other hand, the wax adhering to the candlestick is removed by peeling it off with the tip of a wire or a spatula.

(Problem to be solved) In this way, with conventional candle holders, the wax that remains after the candle burns out adheres to the candle holder wick and its surroundings, and the user must use a tool such as a spatula to remove it. Each time a candle is used, the amount of wax that adheres increases, and when the amount of wax that adheres increases, the state in which the candle is supported by the candle holder becomes unstable, and there is a risk that the lit candle will fall.

The present invention solves these problems by automatically removing unburned wax from the previously burnt out candle from the vicinity of the candlestick when lighting a candle. To provide a safety lamp in which the candle is supported in a stable state by removing the candle, and is also surrounded by a fire pit to prevent the flame from being extinguished by the wind and keep it safe. be.

(Means for Solving the Problems) The present invention provides: (a) an openable and closable firebox that surrounds at least the upper side of a candlestick wick; (b) a firebox that is suspended from a movable receiving member and associated with a locking mechanism By pushing down the movable receiving member by a predetermined amount against the elastic biasing force of the elastic body, it engages with the locking part of the locking mechanism and is temporarily locked. (c) an operating rod having an engaging portion that is disengaged from the locking portion of the locking mechanism by further pushing down and moving against the elastic biasing force of the elastic body from the stopped state; and (c) this operation. The rod is rotated by pressing down and moving, and this rotation rotates a predetermined angle to open the firebox, and the locking portion of the locking mechanism and the engaging portion of the operating rod are released to release the elastic force. A safety lamp comprising: a rotation mechanism that is reversely rotated to close the firebox by returning the operating rod due to the elastic biasing force of the body.

Further, in the present invention, (a) a downward elastic biasing force is applied by another elastic body provided below the candlestick, and wax adhering to the candlestick is removed. (b) an operator having a scraping tool; (b) attached to a moving rod that hangs down from the movable receiving member, the operating element that engages the operating element is raised only when the movable receiving member is pushed down and moved; It is preferable that the movable receiving member is provided with a mechanism for removing the wax and reversing the direction of action of the disengagement movement when the movable receiving member is returned.

(Function) In the safety lamp of the present invention having such a configuration, when the operating stick is pushed down, the locking mechanism associated with the operating stick is interlocked with the engaging part attached to the operating stick and the locking mechanism. The operating stick is temporarily locked by engaging with the locking portion.

At the same time as this operation, the rotating mechanism is rotated by the operating stick, and the firebox connected to this rotating mechanism is opened at the top of the candlestick.

When the burner is open and a lit candle is placed on the candlestick and the control stick is pushed down, the locking part will be displaced far beyond the engagement position with the engaging part on the control stick side and will not engage. The lock is released by the displacement movement of the lock mechanism. Then, the operating stick is pushed back by the restoring force of the elastic body that was pressed and biased at the end of the operating stick.
At the same time, the rotating mechanism is rotated in the opposite direction, and the firebox connected to these fireboxes is closed, and the lit candle is enclosed by the firebox. As a result, the candle remains safe from being extinguished by the wind.

Furthermore, by providing a mechanism for reversing the operating direction of the rotation attached to the operating stick in response to the opening operation of the fire pit, the attached operating element is raised and the operation is performed. A scraping tool for removing the wax attached to the candlestick scrapes off the wax attached along the candlestick. Note that when the operating rod is pushed back, when the upward force applied to the operating element is released, the operating element and the attached scraping tool are immediately lowered by the elastic body.

In this way, before placing a candle on the candlestick, the scraping tool must scrape off any unburned wax adhering to the candlestick, and then the candle that was placed is placed in the firemaker. fenced and kept safe.

Then, the operating element 37 is raised by the rack 38 that meshes with the secondary gear 35, and the scraping tool 40 provided at the top thereof is moved upwardly along the candlestick core 3, and the tip of the scraping tool 40 is moved up. The unburnt wax adhering to the candlestick wick 3 is scraped off by the blade.

To set up a candle, the fire house 20 is open, so use the candle A lit on the candle holder wick 3.
, and then further push down the movable receiving member 4 from the locked state. Then, as shown in FIG. 9c, the engaging portion 8 of the operating rod 5
is further pushed down, the link 14 equipped with the actuator 11 is displaced, and the connecting link 17
is pushed up, the upper link 15 is rotated upward around the shaft 13, and the locking piece 16 disengages from the locking pawl 6. Then, the rotating arm 23
In addition, a pushing force is applied to the operation stick 5 by the restoring force of the return spring 25, which has been compressed and stored, and as the operation stick 5 rises, the rotating arm 23 is also rotated in the opposite direction, and as it returns to its original position. , the firehouse 20 is also closed (see Figure 9d).

Note that when the operating rod 5 is released from the locking force of the locking mechanism 10 and rises, both moving rods 30, 30 also rise in synchrony, so that the gears 33, 33 that mesh with the respective racks 31, 31, Each rotates in the opposite direction.
At the start of reverse rotation of the gears 33, 33, the pawl gear 3
4 and the claw piece 36 on the side of the secondary gear 35 loosely supported on the boss 33' of the gear 33, the locking force on the secondary gear 35 is also released, and the secondary gear 35 is becomes free and this secondary gear 3
The operator 37, which had been raised via the rack 38 engaged with 5, was held in tension by the tension spring 39.
The scraping blade 40 is immediately pulled down by the force, and the scraping blade 40 is instantly lowered and returned to the standby position (see FIG. 9d').

As a result, the lit candle A placed on the candlestick wick 3 on the saucer 2 is
It is surrounded by a fence and is kept in a safe state as a light without being affected by the outside. Note that air flows into the interior surrounded by the firebox 20 from the air formed between the saucer 2 and the lower end of the firebox 20, and combustion gas flows out from the open area at the top of the firebox 20. The flame does not go out due to the fluidity of the emitted air.

(Effects of the Invention) Since the safety lamp of the present invention is configured as described above, the lit candle is securely placed on the candlestick wick, and is protected from the fire pit while it is being lit as a lamp. It is safe because it prevents the fire from extinguishing. In addition, by using a fire shop,
It can be used as a lamp to increase its illuminance.
