Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on a gas rubber hose winding device, has a simple structure, can automatically wind up a gas rubber hose, and has improved durability and safety. are trying to provide.

Traditionally, for tabletop gas appliances where a rubber hose for gas is drawn from the gas pipe to the table, it has been necessary to wrap or bundle the rubber hose when storing it after use. In addition to being troublesome, the rubber hose itself got in the way, making storage inconvenient.

In order to solve this problem, it is possible to wind up the rubber hose with a take-up reel, for example, like an electric cord after cleaning, but in this case, the connection between the connection port of the winding device and the gas appliance. If the opening is fixedly connected with a rubber hose, there is a risk that the hose will twist as the reel rotates and the conduit will be blocked. Therefore, it is necessary to rotatably connect the connection port of the gas appliance and the connection port of the winding device using a rotary joint, etc. In this case, the joint part must be connected to completely prevent gas leakage. This requires a precise seal structure, which results in a complicated structure for the force seal part, and also poses a problem in durability. Therefore, at present, a Halil type rubber hose winding device has not yet been put into practical use.

Meanwhile, conversion work to natural gas has been progressing steadily recently, and it has become possible to use smaller inner diameter rubber pipes instead of the conventional relatively large diameter ones. I came. Therefore, if an appropriate winding structure is developed, it will become possible to roll up and store the cable in the same way as electrical wiring monthly cords.

Therefore, the present invention takes into consideration the above-mentioned circumstances and provides a gas rubber hose winding and collection device that has a simple structure and is excellent in durability and safety. A plurality of divided pieces that serve as winding members for the hose are slidably attached to the slide, and each divided piece is constantly urged outward by a spring so that the whole can expand radially. Furthermore, a stopper groove is formed in the fixing member along the sliding direction of the divided piece, and a stopper claw is provided in the other divided piece to fit into the stopper groove and stop the expansion thereof, and further, the above-mentioned The present invention is characterized in that a lock release member is provided corresponding to each of the stopper claws to release the fitting of each stopper claw from the stopper groove.

Next, examples of how the present invention will be implemented will be described below with reference to the drawings.

(8) is a winding member for a rubber hose consisting of a plurality of divided pieces (31), and this winding member (8) has convex portions provided at both ends of each divided sail so that it can be expanded radially. installed. One side of the slide groove is formed as a sawtooth stopper. Also, the divided piece (3J
In the case of the figure, the cylindrical body is divided into four parts, and when used as a slide groove, the divided pieces (311K corresponding saddle are equally divided in shape). ) is constantly pulled outward by a spring (8) fixed to the outer periphery of the fixed part (2+1 C1l. Therefore, the rolled-up material 81'1 (8) usually expands radially. .Furthermore, each of the divided pieces CIJI has its convex i1

It is constantly pressed in the direction of protrusion at the fixed k [2
+) It fits into the serrated stopper groove formed on one side of the slide 1 of f2+1, and functions to lock the slide of the divided piece 011. However, as shown in FIG. 2, the stopper groove is formed so that the stopper surface (2) is perpendicular to the radial direction so as to limit only the outward cutting of the stopper claw Ce.

Therefore, only the outward movement of the divided pieces C11Iri is locked, and they can freely move toward the center.

Next, (4) is a forest-like lock # removing member arranged radially from the inside of the fixed shaft, and the dividing piece c111 is equipped with CG L,
The sleeve-like attachment is provided to face each of the stopper claws (2) and the active part G1υVill 1.
It is fitted so as to rotate together with the stationary vehicle (CO), and the rotation presses the stopper claw (2) to release the fitting with the stopper groove (CO). With this release of the fitting, each divided piece t311 f''i further slides outward. That is, as long as the winding member (8) and the V10 release member (4) are rotated, they further expand radially. The lock release member (4) can be opened by rotating the lock release member (4) using the L turntable (5
). (61) is a lever for rotation operation.

The above-mentioned winding device (1) has its winding member (8) wound around the rubber hose (6) for K gas, with one end (5) connected to the connection port (a) of the gas appliance. Fixed board CI! 1) The rubber hose can be attached to the gas appliance side or used alone with a cover etc.

The winding member (3) may be implemented by forming a circumferential groove (c), which is a spiral groove, in each divided piece c31) in order to prevent the rubber hose from being rolled up misaligned. In addition, each divided piece 31J is equipped with a rotating roller (r
) may be installed (see Figure 8). Further, as means for forcibly sliding the divided pieces (311) outward, a compression spring may be used to press the divided pieces (317 outward from the center).

In addition, the hose winding device (1) according to the present invention can be implemented with various modifications, such as those shown in FIGS. 9 and 1.

The spring (
It is pressurized downward at point 8) and passes through the stopper claw. Therefore, in this case, the slide lock of the divided piece +311 can be released by lifting the lock release member (4) upward against the spring (S). It is preferable to attach the divided piece CIIJ to the slide par (goods) through a slide bearing, since this can effectively prevent the split piece from coming loose. In addition, the slide bar (to) is arranged in a pair of upper and lower parts to create a divided piece (cll).
Of course, it is also possible to support both sides.

The winding member (3) consisting of a plurality of divided pieces (3D) is expanded by a spring (S) as a means for winding and storing a rubber hose. Since the rubber hose is wound around the rubber hose due to the difference in the outer diameter before and after the expansion member (3) is expanded, even if one end of the rubber hose is fixedly connected to the connection port of the gas appliance, the rubber hose will not fit. It is possible to take up the winding system, does not require a rotary joint like the reel system, has a simple structure, eliminates concerns about gas leakage, etc., and is extremely reliable and durable.

Moreover, since the lock release member (4) is provided in correspondence with the stopper claw G31 of the divided piece c31), the rubber hose can be rolled up with one touch by rotating the lock release member (4), etc. You can also pull out the rubber hose by simply pulling the rubber hose.
It is also extremely convenient in terms of handling.

Therefore, we can provide a gas rubber hose winding and storage device that has various excellent effects such as a simple structure, excellent durability, safety, and low price. This makes it possible to eliminate the troublesomeness of storing gas appliances as described above, and also to store them in an attractive manner.
