Definitions

  • the present invention relates to the structure of a heel portion (hereinafter referred simply to as a heel) of a high heel shoe or the like of which lower end portion that is called a lift can be exchanged with a new one.
  • a conventional high heel shoe is also constructed such that its lift can be exchanged with a new one.
  • the high heel shoe includes a lift 1 which is integrated with a connection shaft 2 having a substantially semicircular sectional shape, and the connection shaft 2 is slightly tapered in the upward direction such that its upper end has a slightly reduced sectional area.
  • a receiving hole 4 having the same sectional shape as that of the connection shaft 1 is formed through the bottom surface of a heel 3 of the high heel shoe so that the connection shaft 2 is fitted into the receiving hole 4.
  • an inner diametrical dimension of the receiving hole 4 is determined to be slightly smaller than an outer diametrical dimension of the connection shaft 2.
  • connection shaft 2 is tightly received in the receiving hole 4, it is practically impossible for an unskilled person to disconnect the connection shaft 2 from the receiving hole 4 irrespective of how a high intensity of pulling force is imparted to the connection shaft 2, because the frictional engagement of the connection shaft 2 with the receiving hole 4 is remarkably increased after she wears her high heel shoe for a long time. For this reason, she is unavoidably required to bring her worn high heel shoe to a well-skilled repairing shop in which the worn lift 1 is disconnected from the receiving hole 4 of the heel 3 by actuating a special tool.
  • Another problem is that there is a possibility that the surface of the heel 3 is injured or scratched when the worn lift 1 is disconnected from the heel 3 with a high intensity of pulling force imparted to the lift 1 by actuating a certain tool.
  • the present invention has been made in consideration of the aforementioned background and its object resides in providing a shoe which assures that a worn heel can easily be exchanged with a new one by any unskilled person.
  • a shoe including an exchangeable lift wherein the shoe is characterized in that an anchor plate having a plurality of hook-shaped engagement projections formed thereon is embedded in the upper part of the lift while extending substantially in parallel with the upper surface of the lift in such a manner as to allow the hook-shaped engagement projections to be projected upward of the upper surface of the lift, that an engagement plate is fixedly secured to the lower end surface of a heel located opposite to the upper surface of the lift while extending substantially in parallel with the upper surface of the lift, that a plurality of engagement holes are formed on the engagement plate corresponding to the hook-shaped engagement projections in such a manner that the upper ends of the hook-shaped engagement projections are first inserted through the engagement holes when the upper surface of the lift is located at the insertion/detachment position where the lift is permitted to move along the lower end surface of the heel in the horizontal direction, and thereafter, the horizontal portions of the hook-shaped engagement projections are
  • the shoe is constructed in the above-described manner according to the invention as defined by claim 1 of the claim clause, while the lift is seized at the insertion/detachment position relative to the heel with an operator's hand, the upper surface of the lift is brought in contact with the lower end surface of the heel. At this time, the upper ends of the hook-shaped engagement projections projecting upward of the upper surface of the lift are inserted into the engagement holes formed on the engagement plate.
  • the lift As the lift is displaced toward the attachment position relative to the heel while maintaining the foregoing state, the lift moves in the horizontal direction while the upper surface of the lift is brought in slidable contact with the lower surface of the heel. At the same time, the vertical portions of the hook-shaped projections are displaced toward the other ends of the respective engagement holes. When the lift reaches the attachment position, the horizontal portions of the hook-shaped engagement projections are engaged with the upper surface of the engagement plate, whereby the lift and the heel are firmly assembled together without any possibility that the lift is disconnected from the heel in the vertical direction.
  • the lift Since the lift is released relative to the heel from the immovably seized state that the lift and the heel are firmly assembled together in the horizontal direction till now, the lift can be displaced from the attachment position to the insertion/detachment position,
  • the hook-shaped engagement projections are disengaged from the engagement plate so that the lift can be separated from the heel.
  • a signal piece is fitted into the lower surface of the anchor plate so as to enable the present state of wearing of the lift to be visually recognized by a user.
  • the user can visually detect the present state of wearing of the lift by way of exposure of the signal piece to the outside.
  • the signal piece is molded of the same synthetic resin as that of the lift, e.g., a polyurethane resin.
  • the lift is colored with black, while the signal piece is colored with a different color, e.g., a red color.
  • the reason why the signal piece is molded of the same synthetic resin as that of the lift in that way consists in that the signal piece is intended to wear at the same rate as that of the lift.
  • a characterizing feature of the signal piece additionally fitted to the lift according to the invention as defined by claim 2 of the claim clause consists in that excessive wearing of the lift can earlier be detected when the signal piece is disposed at the rear part of the lift (i.e., on the back side of the lift) where the lift wears at a higher rate.
  • a shoe including an exchangeable lift, wherein the shoe is characterized in that an anchor plate having at least one hook-shaped engagement projection formed along a part of a cylindrical cup-shaped plane thereof is embedded in the upper part of the lift in such a manner as to allow the hook-shaped engagement projection to be projected upward of the upper surface of the lift, that an engagement plate is fixedly secured to the lower end surface of a heel located opposite to the upper surface of the lift while extending substantially in parallel with the upper surface of the lift, that an engagement hole is formed along a part of the outer peripheral edge of the engagement plate corresponding to the hook-shaped engagement projection so as to allow the upper end of the hook-shaped engagement projection to be inserted through the engagement hole, that a part of the heel located above the engagement hole is recessed so as to avoid interference with the hook-shaped engagement projection, that a pin hole having the opposite ends thereof kept closed is vertically formed through the lower end part of the heel, the engagement plate and the anchor plate at the attachment position
  • the anchor plate and the hook-shaped engagement projection are arranged one above another in the coaxial relationship, and the lift is arranged at the angular insertion/detachment position relative to the heel so that the hook-shaped engagement projection is aligned with the engagement hole. While the foregoing state is maintained, the upper surface of the lift is raises up to come near to the lower end surface of the heel. Subsequently, the upper end of the hook-shaped engagement projection projected upward of the upper surface of the lift is inserted into the engagement hole of the engagement plate.
  • the lift When the lift is turned relative to the heel to assume an angular attachment position, it performs turning movement while the upper surface of the lift is brought in slidable contact with the lower end surface of the heel. When it reaches the angular attachment position, the horizontal portion of the hook-shaped engagement portion is completely engaged with the upper surface of the engagement plate, whereby the lift and the heel are firmly assembled together without any possibility that the lift is disconnected from the heel in the vertical direction.
  • the pin hole on the lift which is located at the position offset from the center line of the anchor plate and the engagement plate, is aligned with the hole on the heel. This causes the locking pin to be displaced in the downward direction by the resilient force given by a pin spring until the lower end of the locking pin is fitted into the pin hole on the anchor plate of the lift.
  • the bottom surface of the lift intersects the bottom of the pin hole.
  • a hole appears on the bottom surface of the lift.
  • a pin having a small diameter is inserted through the foregoing hole from below so as to raise up the locking pin against the resilient force of the pin spring.
  • a signal piece is fitted into the lower surface of the anchor plate so as to enable the present state of wearing of the lift to be visually recognized by a user.
  • a shoe including an exchangeable lift, wherein the shoe is characterized in that an anchor plate of which both sides are bent in the U-shaped sectional contour to form a pair of first parallel rails and which has at least one hook-shaped engagement projection formed at the central part thereof by bending so as to allow it to stand upright between both the bent side parts thereof is embedded in the upper part of the lift while extending substantially in parallel with the upper surface of the lift in such a manner as to allow the first parallel rails and the hook-shaped engagement projection to be projected upward of the upper surface of the lift, that a pair of second parallel rails exhibiting the U-shaped sectional contour by bending and engageable with the first parallel rails are attached to the lower end part of the heel located opposite to the upper surface of the lift, that an engagement plate is secured to the second parallel rails while extending substantially in parallel with the upper surface of the lift, that an engagement hole is formed on the engagement plate corresponding to the hook-shaped engagement projection on the upper surface of the lift in such a
  • the lift is first placed at the insertion/detachment position offset from the heel in the horizontal direction, and thereafter, while the foregoing state is maintained, the upper surface of the lift is raised up to come near to the lower end surface of the heel. Subsequently, the upper end of the hook-shaped engagement projection is inserted into one end of the engagement hole on the engagement plate.
  • the upper surface of the lift moves in the horizontal direction while the upper surface of the lift is brought in slidable contact with the lower surface of the heel and the side surfaces of the first parallel rails are brought in slidable contact with the side surfaces of the second parallel rails.
  • the vertical portion of the hook-shaped engagement projection is displaced toward the other end of the engagement hole of the engagement plate.
  • a signal piece is fitted into the lower surface of the anchor plate so as to enable the present state of wearing of the lift to be visually recognized by a user.

  • the lower surface (the upper surface as seen in Fig. 20) of the heel 3 is recessed in the rectangular contour to form a mounting surface 3a at the bottom of the rectangular cavity.
  • a part of the mounting platform 3a corresponding to a rectangular engagement hole 13 on the engagement plate 8 is recessed to have a large depth, while a pin hole 3c and a fixing shaft hole 3b are formed on the mounting platform 3a at the positions located in alignment with the stopper hole 8a and the fixing shaft hole 8b on the engagement plate 8.
  • a fixing shaft 9 having a number of slantwise knurled portions 19a formed therearound is used in the same manner as the embodiment of the present invention as defined by claim 2 of the claim clause.
  • a locking pin 11 and a pin spring 12 serving as a compression spring for biasing the locking pin 11 in the downward direction are preliminarily received in the pin hole 3c on the heel 3 side before the engagement pin 8 is fixed to the heel 3 with the aid of the fixing shaft 9.
  • the locking pin 11 is designed in the form of a stepped pin including a cylindrical larger diameter sleeve portion in which a pin spring 12 is received.
  • the distance between the pair of first rail portions 14, the distance between the pair of second rail portions 15 and the relative positional relationship between the first rail portions 14 and the second rail portions 15 are determined in such a manner that when the lift 1 is secured to the heel 3 as shown in Fig. 23, the first rail portions 14 are held in the second rail portions 14 in the clamped state while maintaining a gap of, e.g., about 0.03 mm therebetween.
  • the engagement projection 6 is displaced in the horizontal direction.
  • the hook-shaped engagement projections 6 may be displaced in the transverse direction as shown in Fig. 24. In this case, a quantity of displacement required by the hook-shaped engagement projection 6 can be reduced but there arises a necessity for modifying the contour of the engagement hole 13 to a L-shaped one.
  • a worn lift can easily and simply be exchanged with a new one by an unskilled operator.
  • the present invention can equally be applied to all the kinds of shoes with advantageous effects.

Abstract

L'invention se rapporte à une structure de talon de chaussure et, plus particulièrement, à une chaussure pourvue d'un bon-bout qui peut être remplacé facilement et simplement. A cet effet, des saillies en forme de crochets (6) sont prévues sur la partie supérieure du bon-bout et, en outre, une plaque de prise (8), fixée à la surface terminale inférieure du talon, comporte des trous (13) dans lesquels s'engagent les saillies (6) lors de tout mouvement ou de toute rotation du bon-bout par rapport au talon, pour que l'interpénétration entre les saillies et la plaque de prise (8) puisse bloquer à la fois le bon-bout et le talon contre tout mouvement vertical, et, de plus, un goujon de blocage (11), amené à agir dans la direction d'approche du bon-bout, est placé dans un trou traversant le talon et le bon-bout lorsque ce dernier est fixé au talon, afin de bloquer le bon-bout et le talon contre tout mouvement horizontal.
