In addition, the elevating tool of the kite disclosed in Patent Document 1 includes a pair of pulleys 40 and 41 over which one string 45 is stretched, but from one string and one pulley. There is also a known eaves lifting tool configured (for example, Patent Document 2).
Patent Document 2 states that “the U-shaped frame is inserted into the upper frame of the blind attached to the window frame or the like at a position where the load on the left and right of the blind is averaged, and the screw is inserted into the U-shaped frame. The upper frame of the blind is fixed, the string is pulled out from the winder and applied to the pulley, and further, the string is passed through the ring that is tied to the horizontal bar of the blind with a connecting tool, and is locked to the lower frame of the blind. " Patent Document 2, Paragraph No. 0005 in the detailed description of the invention, discloses a kite lifting tool.
Hereinafter, a kite lifting tool provided with a pair of pulleys on which one string is stretched is referred to as a “pair pulley type lifting tool”, and a kite lifting tool composed of one string and one pulley. Is called "single pulley type lifting device".

Registered Utility Model No. 3001041 (for example, paragraph number 0002, FIG. 3 etc. in the detailed description of the invention) Japanese Patent Laid-Open No. 2001-46219 (for example, paragraph number 0005, FIG. 1, FIG. 3 and FIG. 4 in the detailed description of the invention)

Such a conventional lifting tool for a kite has a pulley (part of the engaging portion) attached to the upper portion of the kite and a string (wire) engaged with the pulley. ) Is taken up or loosened, and the lower end portion of the heel supported by the string (wire) is moved up and down.
The pulley (a part of the engaging portion) is attached to the upper portion of the ridge. The U-shaped frame 1 (shown in FIG. 3 and FIG. 4 of Patent Document 2) has a width for fitting the upper frame of the blind, and the pulley. This is often done by sandwiching the upper part of the heel from one side and the other side. If the upper part of the heel is sandwiched from one side and the other side with a width determined like the U-shaped frame 1 and a pulley (part of the engaging part) is attached to the upper part of the heel, the pulley to the upper part of the heel (Part of the engaging portion) can be easily and quickly attached. However, if a pulley (a part of the engaging part) is attached to the upper part of the coffin only by holding the upper part of the coffin from one side and the other side with a determined width, the upper part of the coffin is separated from the one side and the other side. In many cases (for example, the first width between one side and the other side of the upper part of the heel, and the upper part of the ridge as one side like the U-shaped frame 1). When comparing with a predetermined second width that is sandwiched by what is sandwiched from the other surface side, if the second width is slightly smaller than the first width, the clamping force increases, This may cause problems such as difficulty in mounting the U-shaped frame 1 or the like on the upper part of the kite or damage of the kite during the installation.) Therefore, when using the lifting tool for the kite, Part) moved unexpectedly along the upper edge of the fence. For example, if the kite is moved up and down in a state where the position of the string (wire) is moved unexpectedly due to receiving wind or being caught by a moving object (for example, a person or a bicycle), the pulley (part of the engaging portion) Moves unexpectedly along the upper edge of the fence. If this unexpected movement occurs, the kite cannot be raised or lowered well, so it is necessary to return the pulley (part of the engaging portion) to the original position of the upper edge of the kite (the pulley (part of the engaging portion). ) Is usually located at a high position, so returning the pulley (part of the engaging part) to its original position can be difficult.) Such unintentional movement is inconvenient to use the elevating tool. To do.

In order to prevent the pulley (a part of the engaging portion) from moving unexpectedly along the upper edge of the kite, in the kite lifting tool described in Patent Document 2, a U-shaped frame is fitted into the kite upper portion. Further, a set screw 3 is inserted into the screw hole 2 so that the U-shaped frame and the upper portion of the collar are fixed. If the pulley (part of the engaging part) is attached to the upper part of the ridge by screwing in this way, it is possible to prevent unexpected movement along the upper edge of the pulley (part of the engaging part) as described above. However, the work of attaching and removing the pulley (part of the engaging portion) to the upper part of the heel takes time and effort.
Further, the U-shaped frame 1 shown in FIG. 3 and FIG. 4 of Patent Document 2 is used to clamp the upper part of the ridge from one side and the other side, thereby moving the pulley (the engagement portion). When attaching a part), it is necessary to prepare each U-shaped frame 1 according to the dimension (thickness) between the one side and the other side of the upper part of the kite. It was necessary to prepare many types of kite lifting tools to install the kit (manufacturers and sellers of kite lifting tools are forced to manufacture and handle small quantities).

 Therefore, in the present invention, it is possible to easily and quickly attach to the upper part of the ridge, and it does not move unexpectedly along the upper edge of the ridge. An object of the present invention is to provide an engagement portion used for a kite lifting tool that can cope with a certain change in (thickness).

An engagement portion (hereinafter referred to as “main engagement portion”) used in the kite lifting tool of the present invention is attached to a wire rod that supports the vicinity of the lower end of the kite and the upper end of the kite and engages with the wire rod. An engagement portion for use in an elevating tool comprising: an engagement portion, an abutment portion that abuts near the upper end from one surface side of the heel, and the upper end from the other surface side of the heel A kite lifting tool comprising: another abutting part that abuts in the vicinity; and a distance adjusting means that continuously adjusts the distance between the one abutting part and the other abutting part within a predetermined range. It is an engaging part used for.
Note that the “top” and “bottom” of the fence means a state in which the fence is suspended from above (for example, a support with one edge of the fence above (for example, a building eaves, a pillar of a building, “Upper end” and “lower end” in a state of being supported by being suspended and used by a window frame, a saddle support attached to these, and the like). In addition, the “wire” may be any wire that supports the vicinity of the lower end of the heel and is not limited at all. For example, a string, a thread, a rope, a rope, etc. can do. One side and the other side of the kite are surfaces formed by the kite to block sunlight and other people's line of sight (typically a vertical plane is used when the kite is suspended from above) Often referred to as the front and back surfaces).

The present engaging portion constitutes a kite lifting tool together with a wire rod that supports the vicinity of the lower end of the kite (in Patent Document 1 and Patent Document 2, the string corresponds to the wire rod referred to in the present invention), and the wire rod is engaged with the engagement member. Attached to the vicinity of the upper end of the bag. The engaging portion has one abutting portion that abuts from the one surface side of the heel near the upper end of the heel, and another abutting portion that abuts from the other surface side of the heel near the upper end of the heel, and The distance adjusting means of the main engaging portion continuously adjusts the distance between the one abutting portion and the other abutting portion within a predetermined range, so that the main engaging portion is separated from the one abutting portion. The vicinity of the upper end of the flange can be securely clamped between the other contact portions. The distance adjusting means continuously adjusts the distance between the one abutting portion and the other abutting portion within a predetermined range, so that the dimension between the one surface side and the other surface side of the upper part of the collar ( Corresponding to a certain change in (thickness), the vicinity of the upper end of the ridge can be securely clamped. In this way, the main engaging portion securely holds the vicinity of the upper end of the collar by continuously adjusting the distance between the one abutting portion and the other abutting portion within a predetermined range by the distance adjusting means. Therefore, it can be easily and quickly attached to the upper part of the heel without requiring labor and time as in the case of screwing as described in the prior art. By appropriately adjusting the distance between the abutting portion and the other abutting portion, the distance between the upper end of the heel is surely clamped) By adjusting the distance between the one abutment portion and the other abutment portion within a predetermined range by the adjusting means), the dimension (thickness) between the one surface side and the other surface side of the upper portion of the collar It can cope with a certain amount of change.
In addition, this engagement part can be widely used without any limitation as an engagement part with which a wire rod supporting the vicinity of the lower end of the kite engages in the kite lifting tool. For example, the pair of pulley type lifting tools described above and It can be used as any engaging portion of the single pulley type lifting tool.

The distance adjusting means has a female screw portion fixed to the one abutting portion and a male screw portion screwed into the female screw portion, and the male screw portion rotates relative to the female screw portion. Thus, it may be one that adjusts the distance (the distance between one abutting portion and the other abutting portion) (hereinafter referred to as “screw adjusting main engaging portion”).
If the male screw part that is screwed into the female screw part fixed to the one abutting portion rotates relative to the female screw part, the male screw part is relative to the female screw part in the axial direction (both forward and reverse directions) of the male screw part. Can be moved to. As a result, the one contact portion to which the female screw portion is fixed and the other portion whose relative positional relationship with respect to the male screw portion is limited within a predetermined range with respect to the axial direction of the male screw portion (whether the restriction is direct or indirect). The distance between the contact portion and the contact portion can be continuously adjusted within a predetermined range (by rotating the male screw portion relative to the female screw portion). By configuring the male screw portion and the female screw portion with the distance adjusting means, the distance between the one abutting portion and the other abutting portion can be surely and easily achieved with a simple configuration. Can be continuously adjusted within a predetermined range.

In the case of the screw adjusting main engaging portion, the distance adjusting means has a gripping portion formed on the base end side of the male screw portion, and the other contact portion is between the gripping portion and the female screw portion. The male screw portion may be penetrated.
If the other abutting portion is penetrated by the male screw portion between the grip portion and the female screw portion, the relative positional relationship (of the other abutting portion) with respect to the male screw portion with respect to the axial direction of the male screw portion is determined. The distance between the one abutting portion and the other abutting portion can be surely and easily restricted within a predetermined range, and the male screw portion rotates relative to the female screw portion within the predetermined range. Can be adjusted continuously. In addition, the gripping portion formed on the base end side of the male screw portion can grip the gripping portion by hand and rotate the male screw portion well. The other contact portion is prevented from unexpectedly falling off from the male screw portion between the grip portion and the female screw portion (for example, the grip portion cannot pass through the through hole of the other contact portion through which the male screw portion passes. Or a female screw in which the male screw part is screwed into a penetrating part of the other abutting part through which the male screw part penetrates (the female screw part fixed to the one abutting part is reversely threaded. The change in the distance when the portion is rotated can be increased, and the thread is screwed into the male screw portion, etc.).

In the case of the screw adjustment main engaging portion, the male screw portion can be screwed from either one end side or the other end side of the female screw portion, and the one abutting portion can be configured such that the male screw portion is the same as the female screw portion. One contact surface that contacts the vicinity of the upper end of the flange when screwed from one end side, and another contact surface that contacts the vicinity of the upper end of the flange when the male screw portion is screwed from the other end side of the female thread portion (Hereinafter, referred to as “double-sided contact main engagement portion”).
The male screw portion can penetrate the female screw portion and can be screwed from either one end side or the other end side. When the male screw portion is screwed from one end side of the female screw portion, the male screw portion comes into contact with the vicinity of the upper end of the collar. If the one abutting portion has an abutting surface and another abutting surface that abuts in the vicinity of the upper end of the flange when the male threaded portion is screwed from the other end of the female threaded portion, the male threaded portion of the female threaded portion In either case of screwing from one end side or screwing from the other end side, the one contact portion can contact the vicinity of the upper end of the heel. For this reason, both the abutment surface and the other abutment surface can be used as the abutment surface in the vicinity of the upper end of the bag, so that when one of the surfaces is damaged, the other surface can be used. The use of the engaging portion can be continued, and the state of contact with the vicinity of the upper end of the heel by one contact surface is different from the state of contact with the vicinity of the upper end of the heel by another contact surface. The contact area, the shape of the contact surface, the angle of the contact surface, the roughness of the contact surface (including the presence or absence of protrusions and irregularities, etc.), etc., are varied according to the state near the upper end of the heel. One of the contact surface and the other contact surface can also be selected.

In the case of a double-sided abutting main engaging portion, the one abutting is performed with respect to a reference plane that includes a center point between one end and the other end of the female screw portion and is a plane perpendicular to the advancing and retreating direction of the female screw portion. The surface and the other contact surface are substantially parallel, and the distance between the one contact surface and the reference surface is different from the distance between the other contact surface and the reference surface. There may be.
The reference surface includes a center point between one end and the other end of the female screw portion, and the advancing / retreating direction of the female screw portion (relative to the male screw portion by rotating the male screw portion relative to the female screw portion). This means the direction in which the internal thread portion moves (usually the axial direction of the external thread portion). The one abutting surface and the other abutting surface are substantially parallel to such a reference surface, the distance between the one abutting surface and the reference surface, the other abutting surface and the reference surface, If the one contact surface is in contact with the vicinity of the upper end of the flange (when the male screw portion is screwed from one end side of the female screw portion) and the other contact surface is The distance between the one abutting portion and the other abutting portion can be changed in the case of abutting in the vicinity of the upper end (when the male screw portion is screwed from the other end side of the female screw portion). The change in the distance can be used for various purposes. For example, it can be used to cope with a large change in the dimension (thickness) between the one side and the other side of the heel. May be.

  As described above, the main engaging portion constitutes the kite lifting tool (hereinafter referred to as “the book lifting tool”) together with the wire material that supports the vicinity of the lower end of the kite. That is, this lifting / lowering tool is a kite lifting / lowering tool which has this engagement part and the wire which this engagement part engages and supports the lower end vicinity of a collar.

The lifting tool has a first engagement portion (first book engagement portion) and a second engagement portion (second book engagement portion) that are attached to two different points along the upper edge of the bag. The wire rod is stretched between the first engagement portion and the second engagement portion, and at least when raising the vicinity of the lower end of the flange, the first engagement portion and the second engagement The tension | tensile_strength of the wire rod between parts may increase (henceforth "a pair engagement part book raising / lowering tool").
Thus, it has a pair of engaging parts attached to two different points along the upper edge of the collar, and the wire is stretched between the pair of engaging parts. As shown in Japanese Patent Application Laid-Open No. 2003-133260, the lifting tool for a kite that increases the tension of the wire rod between the pair of engaging portions when raising the vicinity of the lower end has been conventionally used. When the vicinity of the lower end of the pair is raised, at least one of the pair of engaging portions is reduced so that the distance between the pair of engaging portions is reduced by increasing the tension of the wire between the pair of engaging portions. There was a problem of moving unexpectedly. On the other hand, in the pair engaging part main lifting tool, both the first engaging part (first main engaging part) and the second engaging part (second main engaging part) By securely holding the vicinity of the upper end of the flange between the contact portion and the other contact portion, it is possible to effectively prevent the engagement portion from being moved unexpectedly.

In the pair engagement portion main lifting tool, the first engagement portion has one end fixing portion to which one end of the wire is fixed, and a first support portion that is movably supported in a direction along the wire, The second engagement portion includes a second end fixing portion to which the other end of the wire is fixed, and a second support portion that is movably supported in a direction along the wire, and the first support portion and the second support portion. The wire rod is stretched between the first portion and the wire portion between the one end fixing portion and the first support portion, and the wire portion between the other end fixing portion and the second support portion is the lower end of the rod. It may support the vicinity.
In this way, the wire rod is taken out (usually, the wire rod stretched between the first support portion and the second support portion is pulled over). It is possible to change the length of the wire between the part and the length of the wire between the other end fixing part and the second support part at the same time, and it is convenient because the vicinity of the lower end of the heel can be easily raised and lowered It is. If comprised in this way, when raising the lower end vicinity of a collar, the tension | tensile_strength of the wire between a 1st support part and a 2nd support part will increase, but the unexpectedness of these 1st support parts and a 2nd support part is unexpected. Movement is effectively prevented as described above. In addition, the state where the vicinity of the lower end of the rod is supported by the portion of the wire between the one end fixing portion and the first support portion and the portion of the wire between the other end fixing portion and the second support portion is maintained. To make it possible, the length of the wire between the one end fixing part and the first support part and the length of the wire between the other end fixing part and the second support part are larger than a predetermined value. You may make it further have the length limiting means to restrict | limit.

  The lifting tool may be manufactured or sold as a finished product in which the main engaging portion and the wire are assembled. However, since a general-purpose wire is readily available, only the main engaging portion is used. Manufacture, sale, etc. may be performed, and also manufacture, sale, etc. may be performed as a production set which manufactures this lifting tool which includes this engagement part and a wire rod at least.
