Abstract

PURPOSE:To enable a hose or the like to be extended to a desired position and put in storage, by urging a reel in the direction, in which the hose or the like is wound, by a spiral spring further stopping rotation of the reel in the desired halfway position of the hose or the like by a rotation control means. CONSTITUTION:If a hand is detached from a hose 2 drawing it out in a position P2 when an adapting piece 65 is placed in a position P1, a device, which rotates an annular member 51 in an urging direction 47 by a spiral spring 41 guiding the adapting piece 65 by the first step differenced surface 57 to reach a stop recessed part 59 via a position P3 from the position P2, stops the hose by fitting the adapting piece 65 of a stopper 52. Next the device, if the hose 2 is a little drawn out when it is stored, moves the adapting piece 65 to escape from the recessed part 59, and the adapting piece 65, which moves over the second step differenced surface 62 from a tilt surface 61 via a guide surface 60 moving from a position P6 to P7, is relocated to an outer annular groove 54. And if the hand is released, the hose 2 is wound by the spring 41, then the adapting piece 65, continuously running riding over the third step difference surface 63 of the groove 54, stops in a condition that a stopping piece 8 is adapted to an adjusting cylinder 7. While the hose, when its winding is stopped in the halfway, is pulled, and the hand is released by moving the adapting piece to positions P10-14.

Description

Description: TECHNICAL FIELD The present invention relates to devices for winding flexible elongate bodies, such as hoses for transporting fluids and for conducting electrical power (electrical cords, etc.).

BACKGROUND OF THE INVENTION In medical facilities such as surgical hospitals, medical equipment is connected to outlets that supply gases such as air, oxygen, and laughing gas to use the desired gas. It is desirable that such an outlet be provided within reach of the user, and it is also desirable that it be provided at a remote location so that it does not get in the way when not in use.

Problems to be Solved by the Invention An object of the present invention is to provide a long body in which a long body such as a hose connected to an outlet can be extended to a desired position and can be stored. An object of the present invention is to provide a winding device.

Means for solving the problem of stress The present invention comprises a main body provided at a fixed position, a reel for winding a longitudinal body rotatably provided on the main body, one end fixed to the main body and the other end attached to the reel. fixed,
There is a spring-biased spring on the reel in the direction in which the first body wraps around the reel, and an I! on the reel. (l) a reel rotation control means which is provided in series and which enables the reel to be pulled out against the spring force, and which stops the rotation of the reel midway when the elongated body is wound around the reel by the spring force; 1 is a winding device for a long body, characterized in that:

In a preferred embodiment, the reel rotation control means is an annular body fixed to the reel, and the annular body has an inner annular groove concentric with the reel and an inner annular groove concentric with the inner annular groove on the side of the annular body. The outer annular groove is formed at intervals in the radial outward direction, and is connected to the inner annular groove and the outer annular groove, which are arranged at intervals in the circumferential direction! nl Oue VfI&2! having a groove,
Such an annular body, which fits into the inner annular groove, the outer annular groove, the first communication groove, and the second communication groove of the annular body, is capable of being displaced in the radial direction, and is prevented from being displaced in the circumferential direction. The PjSi communication groove has a generally V-shaped overall shape, is lower on the downstream side of the inner annular groove in the spring biasing direction, and is lowered on the downstream side of the inner annular groove in the spring biasing direction. It has a first r2 difference surface that extends diagonally across, a stop recess that opens toward the upstream side in the spring biasing direction, and a second step surface that is higher than the outer annular groove on the radially inner circumferential surface of the outer annular groove. The second surface communication groove extends diagonally inward in the radial direction along the direction of the spring biasing force, is lower on the upstream side of the outer annular groove in the spring biasing direction, and extends diagonally across the outer annular groove. It is characterized by having a third stepped surface extending across.

According to the present invention for cattle, the reel for winding the baby body is biased by a spiral spring in a direction in which the baby body is tightly attached to the reel. The reel rotation control means pulls the elongated body against the spring force of the spiral spring, allowing the elongated body to be pulled out from the reel. Therefore, it becomes possible to arrange the long body at a desired position. This reel spinning control means makes it possible to stop the spinning of the reel at a desired intermediate position of the baby body when the reel is rotated by the spring force and the baby body is wound around the reel. This makes it possible to pull out the long body from the reel by a desired length.

The hose outlet 3 is suspended from the ceiling within reach, and in this state, the locking piece 8 is attached as shown in Figure 8 above.
is in contact with the adjustment tube 7. From this state, the hose can be pulled out to any desired length, for example up to 5 lengths, and used. When you first pull out hose 2, then let go, that hose 2 gets caught up a little and stops, and then hose 2 is pulled out.
When the hose 2 is pulled out and released, the hose 2 is wound up without stopping and returns to the original state shown in FIG. hose 2
When pulling out the hose 2, the hose 2 is pulled manually, and when winding the hose 2, it is pulled in by the spring force of the thinly coiled spring 41. During the operation of drawing out the hose 2, the annular body 51 rotates the inner annular groove 53 in the drawing direction 89, which is the opposite direction of the spring biasing force direction 47.

To describe the operation steps in order: (1) Now, the contact piece 65
is at position P1. (2) When the hose 2 is pulled out and released from the hose 2 at position fiP2, the annular body 5 is moved in the spring urging force direction 47 by the spring force of the spiral spring 41.
1 rotates, and the contact piece G5 moves from position raP2 to position r! 1P3
The stopper 52 is guided by the first stepped surface 57 and reaches a stop recess 59, where the abutment piece 65 of the stopper 52 fits into the stop recess 59 and stops.

(3) Next, when storing the hose 2, when the hose 2 is pulled out a little, the contact piece 65 escapes from the stop recess 59, passes through the guide surface 60, moves from the inclined surface 61 to the second stepped surface 62, and
It moves from position 1iP6 to position P7 and moves onto the outer annular groove 54. (4) This contact piece 65 is at the position of the outer annular groove 54.
When you move to P7, let go of your hand and it will turn into a thin ball 41.
The hose 2 is wound up by the spring force, and the contact piece 65 continues running over the tpJ3 step surface 63 of the outer annular groove 54. (5) The hose 2 is wound up in this manner, and stops in the state shown in FIG. 8 in which the locking piece 8 is in contact with the adjustment piece 7, as shown in FIG. This crest abutting piece 65 is at position P
10.

(6) In the above-mentioned operation step (4), the contact piece 65
In the middle of winding up the hose 2 running in the outer annular groove 54,
When you want to stop winding hose 2 at any position,
Pull hose 2. (7) As a result, the contact piece 65
It is guided by the third step surface 63 from the position jJP10 of the outer annular groove 54, passes through the position 1pi1, and goes from the second communication groove 56 to the position P12+ of the inner annular groove 53, 3 Ral: position i?
