JPH01218908A - Spike tire with protrudable/retreatable spike - Google Patents

Abstract

PURPOSE:To enable protrusion/retreat of spike pins by mounting one end of a band plate extending in the tire side direction on an annular bar with a spike pin while connecting the other end with a fastener, and rotating the bar around its axial line by the operation of the fastener. CONSTITUTION:A turn backle 14 is loosened, then annular bars 5, 6 are rotated in the direction of an arrow B by the compression force of a spring 12 through pulling of each band member 4. Consequently, pins 7, 8 are stored in a tire face which contacts the ground. When the backle 14 is rotated reversely, the bars 5, 6 are rotated in the direction of an arrow A reversal to the B direction to provide a spike tire function. The projection/retreat is enabled in this way.

) is provided exposed on the tire (1) C side, and each strip plate (4)
The spring (1) is attached to the bracket (10) installed at the C side end
2) is provided, and a force storage having a line in the direction of the tie t(1)C side is provided. In addition, a plurality of strip plates (3) slightly wrapped around the annular frames (5) and (6) are provided to be exposed on the tire D side, and a scaffold is installed at the end of each strip plate (3) on the D side. It is constructed by sequentially installing turnbuckles (14) on the fixture (13),
By turning each turnbuckle (14) in the direction of arrow F, the spike pins (7) and (8) can rise to the outside of the ground plane (2) and protrude.

Other Embodiments Another embodiment partially similar to the previous embodiment is as follows.

Tighten each turnbuckle (14), so that each spike pin (7), (8) is retracted when the ear (υ) is tightened toward the D side. When each turnbuckle (14) is loosened, each spike pin (73)
, (8) may be made to protrude from the ground plane (2).

As another example of the stored force that indirectly pulls each strip (4) toward the C side of the tire (1), a spring is attached to each strip (4th) along the circumference of the dotted line G from the vanishing point. and tie A
7 (1) may be applied directly toward the center in the radial direction, in short, each strip (4) has a stored force that directly or indirectly tightens the tire (1) toward the C side. All you have to do is apply

Although the annular rods (5) or (6) are two trees in the illustrated example, the number is not limited and may be configured with any number.

The annular ratios 5) and (6) are contained inside the ground plane (2).

In addition, although the illustration shows that the strips (3) and (4) are also slidably contained within the ground plane (2), the annular rods (5) and (6), and the strip (3) , (4) may be provided by making grooves in the ground plane in Figure 1 (as shown by the dotted lines in the two groups).

The attachment of the strips (3), 24) to the annular IFs (IF), (6) is accomplished by attaching spike pins (7), ( 8)
A short piece shorter than that is provided, and a strip plate (3
1 and (4) may be provided rotatably.

The annular rods (5) and (6) are exemplified as ring-shaped formed along the circumference of the tire (1), but they may be made of metal or a similar material in consideration of rotation in the directions of arrows A and B, and strength, etc. It goes without saying that it should be made of a ring-shaped material, but in addition to the ring-shaped one shown in the figure, the following is an alternative system that will make the action easier. Something that is ring-shaped and has broken points. A ring-shaped thing formed intermittently as shown in Fig. 4. Alternatively, as shown in FIG. 5, it may be constructed by connecting at several locations with adjustable joints (15) or the like to form a ring shape.

In Fig. 3, each turnbuckle (14) is arranged and connected in a ring shape, but both ends of each turnbuckle are connected to the strip plate (3) at the dotted line position. They may be fixedly provided, and the turn paras and barrels (14) may be arranged radially when viewed from the center of the tire (1).

As a substitute for the turnbuckle (14), as shown in FIG.
83t-can also be tightened. Although various types of tightening structures can be considered, FIG. 7 shows another type of structure.

The seventh design box 19) is tightened by attaching a single-shaped lever (20) with a pin (21) to the short piece (22) protruding from the pedestal (19) of the tool base 9, and attaching it to the double-shaped lever (20). An arm (23) is provided as shown in the figure, the other end is attached to the end (25) of the strip plate (3), and the hole (26) at the lower end of the pedestal (19) is installed.
Pass the ring-shaped wire (27) through the tire (1
) The nine illustrated fasteners are arranged radially on each side. The illustrated state is one end (2) of the single-shaped lever (20).
4) is in the state of being raised in the direction of arrow H, and the strip plate (3
) on the D side of the tie A7 (1) is in a state of being pushed towards the radial center of the tire (1), and the band plate (3) is loosened by the arm (23). Further, the tightening illustrated in FIG. 7 is another example of the arrangement of the tools, in which shells are sequentially arranged in a ring shape on each adjacent strip plate (3) as shown in FIG. Also good.

For tightening, the tools do not need to be provided one by one as shown in Figure 3, but by forming holes along the circumference at the end of each strip plate (3),
A ring shape, for example, a wire, may be provided through this, and tightening that acts on and tightens the wire may be achieved by providing an appropriate number of tools at appropriate locations 9 so as to act indirectly.

Although the force storage having the tightening force applied to the strip plate (4) is illustrated in FIG. 2, it is of course possible to use other existing force storage structures.

The tightening tool and the installation method of springs etc. are based on the tire (1
)I! Form a structure fixed on the J plane, or as shown in Figure 2.
Although it is installed at a fixed location such as a ring-shaped object as shown by the dotted line in FIG. 3, it is also possible to use a wheel to act as the fixed location.

The mounting of the strips 3) and (4) shown in FIG. The plate (4) is attached, for example, only to the annular rod 5) or the annular rod (6), and another band plate is provided around the annular rod (5) and the annular rod (6), one end of which is wrapped around the other, so that they interlock with each other. Even if you configure it to do so, it can be done.

The illustrated strips (3) and (4) are flat so-called strips, but they can also be made with strings 2, for example ties A7-.

The detailed structure 2 mentioned above, for example, the mounting (13) provided on the strip plate (3) in Fig. 3, the mounting (10) in Fig. 2, the mounting (10) in Fig. 7,
Although the manner in which the portion 25) and the hole (26) are attached and tightened are shown as examples, it goes without saying that they can be done using any existing appropriate method.

In the embodiments shown in Figures 1 to 7, etc., the gist of the present invention was constructed inside the tire contact surface, but the constituent parts were formed as separate structures, and this was covered with a conventional tire. It can be done even if it is done. Figure 8 is an example diagram showing this, (2

The effects of spike pi'A31), (333 etc. are 1st to 7th)
figure.

Of course, the present invention can also be implemented with the same structure and operation as the various embodiments associated therewith. In addition, the covering (29) is one that completely covers the contact surface of the tire (28), and one that covers the entire surface of the tire (28)
8) may be used to partially cover the ground plane, that is, to have a vertical and horizontal or diagonal mesh shape.

The details of the embodiment have been described above, and this is the C side of the illustrated example.

On the D side, tires are not limited to being mounted on the inside or outside. In addition, each part 1, for example, an annular rod (5), (
6), band (3), (4) It goes without saying that the hemorrhoid should be constructed of a material that can fully demonstrate its function.

Effects of the invention As mentioned above, by using a spiked tire that can be moved in and out, the spike pins can be made longer than conventional ones, which not only improves its performance, but also improves its performance on non-snowy and non-frozen roads. It can be used as a regular tire or as a spiked tire by simple operation even when encountering snowy or icy roads. This not only prevents damage to the spike pin, but also prevents unnecessary wear of the spike pin.
