Description

[Detailed description of the device] (a) Technical field to which the invention pertains The device of the present invention can securely and easily fit a California-type cover, and can be carried as appropriate for attaching shoe soles, etc. Concerning plastic lasts.

(b) Conventional technology Plastic lasts for fitting California type covers have been used for a long time.
This last is divided into a front part and a back part,
Since the rear part is fixed and the front part is rotated, when fitting the cover to the last position, grasp the front part at the two-dot chain line position as shown in Fig. 2. All you have to do is push it down in the direction, but at this time, you have to press down the front part of the last with considerable force from above the toe part of the sleeve, so Since the rotation of the front part of the last in the latter half is rapidly restored by the spring, there are drawbacks such as it is difficult to properly fit the cover to the last while gradually adjusting the shape of the cover. Was.

(c) Problems to be solved by the invention The invention is designed to be easily carried while wearing the cover, and is divided into two parts, the front part being fixed and the rear part being the front part. A last made of plastic that is rotatably connected to the end of the last, and which must be held in the correct position with the utmost care when fitting a California type cover to the last. The purpose of the present invention is to provide a plastic last that can be fitted while gradually checking whether the last is in its normal position.

(d) Means for solving the problem The present invention is made of plastic and has a curved split surface that runs from the ankle to the resting area and has a step near the resting part, which separates the front part from the front part. In the last part, which is divided into a rear part, a deep groove is provided in each of the front part and the rear part, and the deep groove opens in the dividing surface and extends in the front-rear direction, and the front part and the rear part are connected within the deep groove. The connecting fitting is rotatably supported astride both, and one end of the <-shaped bar spring is supported around a part of the connecting fitting in the rear part, and the other end is in the front part. It is characterized by being pivotally supported at a position closer to the ankle than in the axial direction of the connecting fitting.

(E) Embodiment FIG. 1 is a side view showing an embodiment of the present invention, in which the last in its normal position is indicated by a solid line, and the upward rotation position of the rear portion 1 of the last is indicated by a two-dot chain line. The cover 3 which is shown and fitted at the position shown by the chain double-dashed line on the rear part 1 of the last is shown by the chain three-dot line,
The cover 3 fitted in the last normal position is shown by a dashed line.

The last is made of plastic,
It is divided into a front part 2 and a rear part 1 along a line from the last ankle part to the non-stepping part.

The parting line 4 has a convex curve on the front part 2 side and a concave curve on the rear part 1 side, and both ends of the parting line 4 are formed closer to the toe part on the non-stepping part side than on the ankle part, A step 5 is provided near the step. The dividing plane between the front part 2 and the rear part 1 of the last is
It is a curved surface in the left-right direction with respect to the last including the dividing line 4.

Deep grooves 6, 6 are formed in the front portion 2 and the rear portion 1, respectively, and extend in the front-rear direction and open in the dividing surfaces thereof. A connecting fitting 7 is housed across both deep grooves 6, 6 of the front portion 2 and rear portion 1, and both ends of the connecting fitting 7 are provided with deep grooves 6, 6 in the left and right direction of the last, respectively.
The front portion 2 and the rear portion 1 are connected to each other by being rotatably fixed to shafts 8 and 9 which are fixed to the last through the front portion. If at least one shaft hole of the connecting fitting 7 is formed into a long hole, the rear portion 2 can be rotated very smoothly.

Further, a substantially <-shaped bar spring 10 is housed in the deep grooves 6, 6 closer to the ankle than the connecting fitting 7. One end of the bar spring 10 is rotatably supported on the shaft 8 via the end of the connecting fitting 7, and the other end of the bar spring 10 is rotatably supported on the shaft 11, which is fixed to the ankle side like the shaft 9. It is rotatably supported. A fixing pin hole 12 is provided on the ankle side of the front portion 2, and a pin hole 13 for a jig is provided on the rear portion 1.
By fitting a suitable jig into this pin hole 13, the rear portion 1 can be rotated without difficulty.

(F) Effect of Action As shown by the solid line in Figure 1, the front part 2 of the last in its normal position is inserted into the pin hole 12 with its ankle side facing downward.
is fixed to a fixing pin (not shown) of the holder, and if the rear part 1 is lifted in the direction of the arrow through the pin hole 13 using a suitable jig (not shown), it will be shown by the two-dot chain line. held in position. At this position, fit the California type clasp 3 from the front part 2 to the rear part 1, and then gradually push down the rear part 1 until the clasp 3 is in its normal position on the toe side of the front part 2. It can be arranged with enough room to be fitted, and at the same time the rear part 1 is returned to the specified position shown by the solid line, the cover 3 is correctly fitted as shown by the dashed line.

In the last made of plastic as described above, by rotating the part 1, the most conspicuous end part of the sleeve 3 is inserted until just before the final step of fitting the sleeve 3 to the last. The front part 2 of the last can be modified, and it is convenient to be able to carry the last freely with the cover 3 attached, and the cover 3 can be removed from the last by simply stepping on the rear part 1. This can be done very easily by rotating to the side.
