のあるスキーを得ることができだ。Traditionally, ski boot fasteners (hereinafter simply referred to as fasteners) have been attached to skis with screws, but in order to strengthen the retention force of the screws, the fasteners are attached by attaching metal plates or other fasteners to the parts. It is common to interpose a reinforcing plate (hereinafter simply referred to as a reinforcing plate) in the core, and in its implementation,
Usually, as shown in Fig. 1, a recessed part 2 into which a reinforcing plate 3 is inserted is provided on the upper surface of the fastener fitting part of the core, and the reinforcing plate 3 is fitted into the recessed part to form a flat surface. This was the way to do it. However, this involves a laborious work process for creating the recessed part 2, and as the skis are repeatedly skied down, bending and torsion stress of the ski and stress applied to the fasteners act strongly on the reinforcing plate 3. When this was inserted, cracks appeared on the edges of the recessed part 2, and a peeling phenomenon appeared on the top surface.On the other hand, plastic injection skis have been commercially available in recent years. In this ski, a flat reinforcing plate is attached to the upper surface of the ski without providing a reinforcing plate on the core. In this case, workability is improved, but since the reinforcing plate is located on the upper surface of the core, repeated bending, torsional stress, etc. that occur while skiing downhill will act most strongly on the part where the fasteners are removed. In the case of foamed synthetic resin, which has a weak body, there was a drawback that the top surface part could be peeled off and damaged as the body was torn off. Therefore, as shown in FIG.
A cedar has also been proposed in which a reinforcing plate 7 for fasteners with protrusions is attached, the lower surface of the cedar is inserted into a mold, and the cedar is integrally molded with a foamed synthetic resin. In this case, the reinforcing plate is buried in the center core, creating an anchoring effect, which improves the retention force of the screws, making it possible to obtain a durable ski without reducing the strength of the ski itself. is.

の位置からずれることがあった。However, when attaching the fastener with the protrusion B provided on the lower surface of the upper surface part IF' 3, the reinforcing plate 7 is glued, so this gluing process is time-consuming, and if the bonding is not ensured, the foamed synthetic resin The pressure during injection and foaming caused the protrusions to peel off from the two sides, and the reinforcing plate on the fastener claw side sometimes moved from its designated position.

This is an injection ski manufacturing method designed to provide inexpensive and durable skis.

/, the lower surface component part 3 with which Nutille edge 72 etc. are pre-adhesively integrated is placed, and then the ski boot attachment is done by attaching a protrusion of arbitrary shape to a predetermined location in the lower mold 10 corresponding to the part.
For mounting fasteners with grooves or protrusions (not shown), use the reinforcing plate 15.
is wound with a tensioning member made of metal wire, fiber thread, etc., the tensioning member/B is tensioned and held in the lower mold 10, and then the upper surface component member/7 is wound. This is an injection ski production method in which the upper mold/g is placed and clamped, and a foamed synthetic resin is injected and foamed and hardened to integrally mold the Siski key at the same time.

In the method for manufacturing injection skino according to the present invention, the fastener is attached by winding the tension member/B around the reinforcing plate/S, then tensioning the tension member/B and stretching it into the lower mold. In order to install and lock the upper surface component member /7 on top of it, place the upper mold and press it, the fastener installation is done using the projection /Il or protrusion provided on the reinforcing plate /S. Make sure to contact member/7,
In addition, since the fasteners are installed by tensioning and locking at least the front and back of the reinforcing plate with the tensioning members/B, the fasteners are attached to the reinforcing plate 7 due to the pressure and foaming pressure when creating and injecting the foamed synthetic resin. .5 can be prevented from moving or being misaligned. ! In order to wrap the tensioning member/B and secure it in the mold, the work process is simplified as there is no need for the traditional method of gluing seven protrusions onto the two-sided component. can be converted into

樹脂中に確実に埋設されるため、耐久性が向」―する。In other embodiments of the present invention, the fastener removal reinforcing plate /S is a synthetic resin plate provided with a synthetic resin plate /9 on which protrusions or protrusions are provided in advance, as shown in Figure S. If a reinforcing plate such as Meckle board, fiber-reinforced plastic board, or 20 plate is used as a reinforcing plate/S on the fastener claw side, for example, the thickness distribution of the ski may be changed in design. Therefore, even when the thickness of the ski becomes thinner or thicker, by adjusting the height of the removable protrusion, the tightening claw side can be used without changing the reinforcing plate/S, which improves the yield of the section. This also greatly improves the degree of freedom in designing the ski itself. Since the reinforcing plate/S is firmly embedded in the foamed synthetic resin, the durability is improved.
