Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a cover sheet take-up device which is used for preventing a decrease in the water temperature of a pool, placing it on a gymnasium mat, and the like.

[Prior Art] The present inventor has already proposed the winder disclosed in Japanese Utility Model Laid-Open No. 61-25372 in order to take out a wide and long heat dissipation sheet from a pool. In the winder, when a handle provided on an upper portion of a support frame erected on the underframe is rotated, a pair of upper and lower expanded blade plates are rotated so that a sheet is wound around the blade plates. Has become. Then, in order to take out the rolled-up sheet, the diameter of the blade is reduced and the sheet is pulled out as it is from the open end.

[Problems to be Solved by the Invention] In the above-described winder, it is necessary to provide an interlocking mechanism between the central shaft and the blade plate in order to expand and contract the blade plate, which makes the device complicated. However, it has a disadvantage that it is troublesome and the center of gravity is concentrated on the upper side, so that it is easy to fall, and that if a part of the interlocking mechanism is hindered, the expansion and contraction action of the blade plate cannot be performed smoothly.

[Means for Solving the Problem] The present invention has been made in view of the above-mentioned conventional problems, that is, a column is provided on one side of an underframe to which casters and stoppers are attached, and the column is fixed to the upper end of the column. For bearings,
Insert a long rotating shaft with a handle at the rear end, and fix a guide plate to the rotating shaft at a position facing the handle with the bearing in between. Secure the rear ends of the lengthy open / close bars at equal intervals, insert the guide pin of the clutch into the tip of the rotating shaft, pivotally attach the link base to the support piece provided in the front of the guide pin, and attach the link end. It is intended to provide a winder which does not have the above-mentioned disadvantages by being pivotally attached to the tip of the opening / closing bar and by interlocking the guide pin with the forward / backward movement of the handle of the clutch tip.

[Operation] Since the open / close bars pivotally attached to the link ends are arranged side by side so as to surround the rotating shaft, for example, the cover sheet taken out from the pool is hung on the outside of the open / close bar. One side is in contact with the guide plate and the other side is open. The cover sheet having one end hooked on the opening / closing bar is wound up by turning the handle at the rear end of the rotating shaft. That is, when the handle is turned, the guide plate also rotates, and the open / close bar having the rear end fixed to the guide plate works together, so that the sheet is gradually taken up by the open / close bar, and finally the entire sheet is hung cylindrically outside the open / close bar. To be dressed. Then, in order to take out the suspended sheet from the winder to store it, first, the handle of the clutch is rotated 90 degrees and the guide pin is rotated and pushed in as it is. Then, the support piece (which does not rotate) also retracts together with the guide pin, so that the link tilts, and the diameter of the opening / closing bar pivotally attached to the link is reduced toward the tip end. It can be pulled out from the front of the rotating shaft.

Further, in order to expand the diameter of the opening / closing bar, contrary to the above, the guide pin may be advanced together with the handle to raise the link vertically and rotate the handle to maintain the state.

[Embodiment] 1 is an underframe having a rectangular shape in a horizontal plane, substrates 2 and 3 are provided on the inner front and rear sides, and casters 4 are provided on the lower surfaces of the substrates. Reference numeral 5 denotes a stopper of the underframe 1 which is movable up and down when a lever 7 of an interlocking rod 6 whose both ends are erected on the rear substrate 3 is operated. When the stopper 5 is stopped at the descending limit position, the entire underframe 1 is removed. Fixed. Further, a cylindrical column 8 is erected on the upper surface of the rear substrate 3, and a bearing 10 is fixed to the upper end of the column via a horizontally long seat plate 9.

Reference numeral 11 denotes a long pipe-shaped rotating shaft inserted in the bearing 10.
A handle 12 is fixed to the rear end of the bearing 10, and a circular guide plate 13 is provided at a position facing the handle with the bearing 10 interposed therebetween.
Is fixed through.

The guide plate 13 is provided with three insertion holes 15 at equal intervals, and each of the insertion holes has an elongated opening / closing bar 16 with a small diameter whose tip portion projects slightly forward of the rotary shaft 11. The back end is stuck. Reference numeral 17 denotes a clutch attached to the tip of the rotary shaft 11, and is composed of a guide pin 18, a support piece 19, and a spindle 20 having a handle T at the tip. The rear portion of the spindle 20 is inserted into the guide pin 18 and is mutually skewed by the stopper pin 21, and both ends of the stopper pin are projected to the outside of the guide pin 18. Further, the support piece 19 is sandwiched between the tip portion of the guide pin 18 and the step portion of the spindle 20, and is interlocked with the forward / backward movement of the guide pin 18 and is not interlocked with its rotation.

The rear end of the normal guide pin 18 is inserted into the front end of the rotary shaft 11, and both ends of the stopper pin 21 are hooked in two recesses M at the rotary shaft end. Support piece 19
The bases of the links 22 are pivotally attached to the three brackets 19a provided at, and the ends of the links are fitted to the notches K provided at the tip of the opening / closing bar 16 and are pivotally attached to each other by the pins P. .

That is, the three open / close bars 16 are positioned in parallel with the rotating shaft 11, and the cover sheet 23 is hung on the open / close bars. When the handle 12 is turned, the rotating shaft 11, the guide plate 13, and the opening / closing bar 16 are rotated to wind up the cover sheet, and the entire sheet is finally set outside the opening / closing bar. And to take out the wound sheet from the open / close bar 16 as it is,
The handle T at the spindle end of the clutch 17 attached to the tip of the rotating shaft 11 is rotated to engage the stopper pin 21 with the long hole N of the rotating shaft formed at a position 90 degrees from the position of the depression M. Push the clutch into the rotary shaft 11. When both ends of the stopper pin 21 are guided to the elongated hole N, the guide pin 18 of the clutch is naturally retracted into the rotary shaft and the support piece 19 is also retracted at the same time. For this reason, the diameter of the opening / closing bar 16 supported by the link is reduced toward the front end portion, so that the sheet 23 is taken out from the front end of the opening / closing bar in a wound state. In order to open the contracted open / close bar 16, the clutch 17 is pulled out to the tip of the rotary shaft 11 by the handle T, both ends of the stopper pin 21 are engaged with the recesses M, and the link 22 is rotated 90 degrees with the rotary shaft 11. It should be projected to the position of.

[Effects of the Invention] The present invention has the following unique effects.

(1) Since the cover sheet is automatically wound around the open / close bar by turning the handle, it is efficient because it does not require time and effort for hanging.

(2) The open / close bar is reduced only by immersing the clutch in the rotating shaft, so that the sheet can be taken out quickly.

(3) The opening and closing bar can be contracted and expanded by an operation of retracting and retracting the clutch, and since the device does not become complicated, there is no danger of failure, durability is provided, and disassembly and assembly are easy, compact storage is possible, and it is provided at low cost.
