DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments for realizing the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, an ice shaving machine 1 according to the present invention basically has the same structure as a conventional ice shaving machine. That is, the same machine has a casing-shaped vertical support frame 2, an intermediate support plate 3 horizontally fixed at an intermediate height position of the support frame 2, and a cutting plate fixed to the intermediate support plate 3. 4 and the vertical support frame 2 above the intermediate support plate 3.
An upper support plate 5 fixed horizontally to the upper plate, a vertical lift shaft 6 rotatably supported by the upper support plate 5 above the cutting plate 4, and a circle fixed to the lower end of the vertical lift shaft 6. At least a plate-shaped ice block holder 7 is provided.

A cutting blade 8 for cutting an ice block (not shown) is fixed to the cutting plate 4 with its tip facing upward, and the lower surface of the upper support plate 5 is shown in FIG. A metal or resin brim-like locking member 9 as shown is attached, and a rotary curved surface-shaped cover member 10 which is a feature of the present invention has the brim-like locking member 9 at the upper end thereof.
It is locked to.

The brim-shaped locking member 9 has a shape which is produced by deep-drawing and processing one brim-shaped disc inside thereof, that is, a large-diameter disc portion 11 and a large diameter. The diameter disc portion 12 is connected in a stepped shape, the former is fixed to the upper support plate 5 with a screw 13, and the latter has a function of locking the cover member 10. Then, two stoppers 14 are provided on the outer peripheral surface side of the large-diameter disk portion 12.
a and 14b are provided at a predetermined interval in the circumferential direction, that is, at a center angle α of slightly smaller than 180 degrees, and when the cover member 10 is rotated in the circumferential direction, an angle of a predetermined range ( It exerts a stopping function that allows rotation by α-γ) degrees. However, γ is the stopper 14
It means a central angle whose arcs are the circumferential lengths of a and 14b.

The cover member 10 includes a cover body 15 made of a transparent resin and having a substantially semi-cylindrical shape, and an annular or semi-annular slide locking portion 16 integrally formed with the cover body 15 itself at an upper end portion thereof. Are formed from. Further, the cover body 15 has a tapered shape that spreads downward, and a reinforcing rib 17 is formed on the outer side of the lower end portion so as to extend in the circumferential direction.

Similarly, on the upper surface of the upper end portion, an upper protrusion 18 that projects slightly above the upper surface of the slide locking portion 16 is provided.
Is provided, and the large-diameter disk portion 12 of the collar-shaped locking member 9 is provided.
On the other hand, when the cover member 10 is rotated while the annular slide locking portion 16 of the cover member 10 is locked, the upper protrusion 18 is attached to the upper support plate 5 by a sensor such as a micro switch ( (Not shown) is operated to stop the rotation of the vertical lifting shaft 6.

Further, on the outer surface of the upper end portion of the cover member 10,
A frictional portion 20, for example, an uneven surface, which allows the cover member 10 to be rotated by touching the surface with a hand, is provided over a predetermined circumferential length.

Further, on the inner surface of the upper end portion of the cover member 10, as shown in FIG. 3, one inward projection 19 capable of abutting on the two stovers 14a, 14b of the collar-shaped locking member 9.
Are provided inward, and when the cover member 10 is rotated in a state where the annular slide locking portion 16 of the cover member 10 is locked to the large-diameter disk portion 12, The protrusion 19 contacts the two stoppers 14a and 14b so that the rotation range of the cover member 10 becomes a predetermined rotation angle β (see FIG. 2).

This rotation angle β is determined by the stopper 14a,
14b mounting positions, their widths, and the circumferential length of the cover body 15 of the cover member 10 (or the opening length L between the circumferential end faces 21a and 21b) and the width of the inward projection 19 Although different, the opening length L is
It is determined to be slightly larger than the circumferential length of the front opening 23 of the ice shaving machine 1 shown in FIG. In the present invention, the length of the opening length L is set to a rotation angle β of 18
Even if it is slightly smaller than 0 degree, preferably in the range of 175 degrees to 160 degrees, and the slide locking member 16 has a semi-annular collar-shaped locking member 9 partially lacking, the former is surely locked to the latter. Thus, not only the function thereof is retained, but also the function of shielding the front side opening 23 formed by the support frame 2, the intermediate support plate 3 and the upper support plate 5 is maintained.

The operation and effect of the cover member 10 in the ice shaving machine 1 having the above structure will be described with reference to FIGS. First, when the cover member 10 is blocking the front opening 23, the friction portion 20 of the cover member 10 is covered.
Is touched by hand to rotate the cover member 10 in the direction of arrow X shown in FIG. 1 (FIG. 1, FIG. 2, FIG. 4). Then, the upper protrusion 18 of the cover member 10 turns off the microswitch to disconnect the circuit of the motor (not shown) for rotating the vertical lifting shaft 6. Then, the inward projection 19 of the cover member 10 comes into contact with the stopper 14b of the collar-shaped locking member 9, and the cover member 1
The rotation of 0 is stopped and the front opening 23 of the ice shaving machine 1 is released (FIG. 5).

Next, as in the prior art, the cutting plate 4
After the ice block is placed on the vertical support frame 2, the vertical handle shaft 22 is rotated by rotating the vertical handle 22 on the upper side surface of the vertical support frame 2.
Is lowered, and the ice block is attached to the cutting plate 4 side by the ice block retainer 7 attached to the lower end thereof.

Again, the friction portion 20 of the cover member 10 is touched by hand and rotated in the direction of the cover member arrow Y (FIGS. 1 and 5). Then, the inward projection 19 of the cover member 10 abuts on the stopper 14 a of the collar-shaped locking member 9, and the cover member 1
When the rotation of 0 stops, the micro switch turns on.
Then, the front opening 23 of the ice shaving machine 1 is shielded (FIG. 4). Next, when the switch (not shown) of the motor is turned on, the vertical lifting shaft 6 rotates and the lower surface of the ice block is cut by the cutting blade 8.

In this series of operation steps, the cover member 10 is composed of a semi-cylindrical rotating curved surface body. Therefore, when the cover member 10 is rotated in the circumferential direction, the disk-shaped ice block holder 7 is pressed. A space formed by the support frame 2, the intermediate support plate 3 and the upper support plate 5 is surrounded by a predetermined distance so as to surround a semicircular locus.

Therefore, the front opening 23 of the ice shaving machine can be shielded in a space-saving manner without substantially changing the shape of the conventional ice shaving machine and without impairing its function. Since the cover member 10 of the present invention is made of transparent resin, the space can be seen through at all times. In this embodiment, since the upper protrusion 18 operates the micro switch, the cover member 10 cannot rotate the vertical elevating shaft 6 when the front opening 23 is in the open state, and ensures safety during ice shaving. it can.

The present invention can be carried out by modifying the above-described embodiment, for example, as follows, within the limit that the effect of the invention is not significantly impaired by following the fundamental technical idea. (1) The rear surface side of the vertical support frame 2 may not necessarily have a wall shape but may have a lattice shape. (2) The vertical lifting shaft 6 may be manually rotated instead of being electrically driven.

(3) The rail member provided on the intermediate support plate 3 may be slid without the cover member 10 being locked to the annular locking member 9. In this aspect, the upper end of the cover member 10 can be guided by the guide member. (4) Friction reducing means such as bearings and lubricants can be provided on the contact surface between the annular locking member 9 and the cover member 10.

[0023]

As described in detail above, according to the present invention, the front side opening portion of the ice shaving machine is space-saving without substantially changing the shape of the conventional ice shaving machine and without impairing its function. It has an excellent effect that it can be shielded by.
