Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a winch that is convenient for use in operating a folding basket support device installed on the ceiling of a gymnasium, for example.

For example, the applicant's earlier application
In the folding basket support device of No. 21711, the basket frame is lifted up close to the ceiling of the gymnasium by rope operation, and folded and stored.
It also has a structure that allows it to be pulled down vertically.

A winch is attached to the ceiling of the gymnasium to wind up ropes for operating such baskets. To operate the winch, an operating wheel such as a chain wheel is installed that is linked to the rope winding drum.
A long annular hand chain is attached to this operating vehicle, allowing it to be operated from below. by the way,
If the hand chain were to come off the chain foil, it would be extremely dangerous for the person operating it below, so make sure that the hand chain does not come off the chain foil, and even if it does come off, there is no risk of it falling downward. A guide member is attached to the winch body to prevent danger.

However, the guide member must always be placed horizontally in relation to the chain, but the slope of the beam on the ceiling of the gymnasium is not always the same for each gymnasium, and in this case no special consideration is required. When the winch body is attached to a ceiling beam, the winch body is not vertically disposed but is attached at an angle.
However, since the conventional guide member is fixed to the winch body by welding means, in the above case, the guide member is disposed at an angle with the winch body. For this reason, each time the slope of the ceiling beam in the gymnasium differs, the mutual lengths of the mounting brackets 20 and 21 in Figure 1 are adjusted (in other words, by using appropriate lengths), so that the winch body is always positioned vertically. It is installed as shown. However, in order to replace and install the mounting brackets 20 and 21 each time the ceiling slope of the gymnasium differs, it is necessary to prepare various types of mounting brackets with different lengths and to work with the existing fittings. This is extremely inconvenient as it does not work.

This invention solves the above-mentioned problem.A guide member is rotatably provided on the winch body and can be fixed at a desired angular position, so that the winch body is always installed tilted to match the slope of the ceiling beam. However, the guide member can always be installed in a horizontal position.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIGS. 2A and 2B are explanatory views showing the state in which the device is installed on a beam with a gentle slope.

In FIG. 1, 1 is a winch main body, and a drum 2 is pivotally supported on side plates 4, 4' of the winch main body, and a wire 6 is wound around the drum 2. 3 is the tsuba of the drum.

A guide plate 7 constituting one member of the guide member 23 is in close contact with the outside of the side plate 4', and the shaft 24 is in close contact with the outside of the side plate 4'.
A chain foil 8 is disposed on the outside thereof. This chain foil 8 is attached to the end of the shaft 24 passing through the side plates 4, 4'. A chain 9 is hung on the chain foil 8 to form a chain block 10.
In the chain block 10, the guide frame 11 is connected to the connecting rods 12, 1 at an interval that does not prevent the rotation of the chain wheel 8 from the outside of the guide plate 7.
It is established by 2.

The guide plate 7 has circular arc holes 1 formed opposite to each other.
3 and 14 are provided, and the tips of the lower connecting rods 5, 5 of the connecting rods 5, 5 for holding the side plates 4, 4' of the winch main body 1 at a predetermined interval are inserted into the arc holes. , Nuts 15 and 16 are screwed into screw portions formed at the ends of the connecting rods 5 and 5 so as to be tightenable and loose. Therefore, the guide plate 7 is rotated by a predetermined angle using the shaft 24 as a fulcrum, and the nuts 15 and 16 are rotated by a predetermined angle.
can be fixed in that angular position.

In the winch, when the annular and long hanging chain 9 is operated from below, the chain wheel 8 is rotated, and the shaft 24 is rotated. A gear (not shown) is attached to the other end of the shaft 24, and this gear meshes with a gear attached to the drum shaft, so that the drum 2 rotates in conjunction with the chain wheel 8, and the wire 6 can be wound up.

Next, in order to install a winch with such a configuration under the beam, angle members 17, 17 are arranged on the upper part of the side plates 4, 4', and the angle members 17,
17 is the support member 1 installed on the ceiling beam 22 of the gymnasium.
Mounting brackets 20 and 21 hung and fixed to 8 and 19
Concatenate. Of course, the installation of the winch 1 under the beam is not limited to this embodiment, and can be done as desired depending on the site.

Therefore, when the winch is installed on the ceiling beam 22 of the gymnasium in this way, the installation angle of the winch body 1 is different along the slope of the beam 22 as shown in FIG. become. However, since the guide plate 7 and guide frame 11 must always be horizontal, in this case,
The nuts 15 and 16 of the connecting rods 5 and 5 are loosened to release the fixation of the guide plate 7, and the guide plate 7 is shifted until it becomes horizontal and the nuts 15 and 16 are tightened. In this way, the winch body 1 can be attached to the beam 2.
Although mounted perpendicular to the slope of 2, the chain block 10 is located below for easy operation.

Figure 2A shows a beam slope of 40°, and in order to attach it to the beam slope of 10° shown in Figure 2B, the guide plate 7 will be tilted by the amount that the slope has decreased. It is sufficient to slide the connecting rod 5 on the right side along the arcuate hole 14 and fix the nut 16 in a position where the chain block 10 is in a substantially horizontal state.

As explained above, the proposed winch has an arcuate hole in the guide plate of the chain block, and is configured so that the guide member can be rotated and fixed at any angle relative to the winch body, thereby improving the slope of the ceiling beam. It is possible to carry out the installation work very easily even when the conditions are different, and the structure is simple, so standardization is easy.
