Description

  The present invention relates to a cover fixing method and apparatus for fixing an elastic cover member to a covered body such as a string or a chain.

  Conventionally, various covers are attached to end portions of strings, chains, and the like. In general, this cover is relatively hard, and it is configured so that the cover does not fall off from the string by being fused, pressed, pinched, or tied to the end of the string. (For example, Patent Document 1 and Patent Document 2).

  In addition, a soft cover may be attached, but the current situation is that it is very difficult to attach because the tip of the string may fray. The method of mounting firmly requires man-hours and an apparatus for mounting, which increases costs and makes the product expensive. The relatively simple attachment method is easy to fray, has a poor appearance, and the product has a poor appearance.

FIG. 28 to FIG. 32 show an embodiment of the product fixing device according to the present invention. In the embodiment, the covered body will be described as a string.

(Technology and configuration related to cover insertion member)
FIG. 1 shows a string 1, and a pipe member 2 as an auxiliary member for fixing, which will be described later, is inserted on the outside. As shown in FIG. 8, the pipe member 2 is a member having a shape in which a part of the outer shape is cut out in the longitudinal direction. Through the cutout portion, the string 1 can be seen from any position across the length. The pipe member 2 can be inserted. The pipe member 2 has a function of preventing fraying of the end portion of the cord 1 and determining a position of the end portion of the cord 1 by pressing a cover insertion member 3 described later.

  FIG. 2 shows a state in which the end portion of the string 1 is matched with the stepped portion 2 a against which the cover insertion member 3 in the pipe member 2 abuts. 3, the cover insertion member 3 is inserted into the pipe member 2 in the state of FIG. 2 and abuts against the stepped portion 2a, and then the string 1 is inserted into the hole 3b provided in the large diameter portion 3a of the cover insertion member 3. The state where it is pushed and inserted is shown. As shown in the figure, the cover insertion member 3 is provided with a hole 3b in the large-diameter portion 3a so that the string 1 can be inserted into the hole 3b as described above. In addition, when the connection strength of the string 1 and the elastic cover member 4 is required and the end portion of the string 1 is inserted, the hole 3b of the cover insertion member 3 may be impregnated with an adhesive.

An intermediate portion of the cover insertion member 3 is a tapered portion 3c and has a conical shape. The other end constitutes a small diameter portion 3d, and a hook-shaped locking portion 3e is provided on the end side. The locking portion 3e is for preventing the elastic cover member 4 inserted into the small diameter portion 3d from coming out of the small diameter portion 3d, and a base point for pushing the elastic cover member 4 into the string 1 side. It will be.
FIG. 4 shows a state where the elastic cover member 4 is inserted into the small diameter portion 3 d of the cover insertion member 3. The elastic cover member 4 is a synthetic soft material having a small-diameter hole 4a at the center. The pushing member 5 is abutted against the end of the elastic cover member 4. FIG. 5 shows a state immediately before the elastic cover member 4 passes through the tapered portion 3c together with the pushing member 5 and is held by the large diameter portion 3a and pushed into the string 1 side.

  The elastic cover member 4 has elasticity and has a restoring force, and is a kind of rubber or elastomer synthetic resin, and is a synthetic soft material as described above. When passing through the taper portion 3c, the taper is pushed while being expanded by elastic deformation and is pushed while being compressed in the axial direction. The pushing member 5 also passes through while being elastically deformed, but it may be pushed with a pliers 6 as shown in FIG. When the pliers 6 are gripped, the gripping portion 6 a at the tip is opened. One end of the gripping portion 6 a is abutted against the hook-shaped locking portion 3 e of the cover insertion member 3, and the other end is brought into contact with the pushing member 5. When gripped, the gripping portion 6a opens and the elastic cover member 4 is pushed into the string 1 side.

  The tool for pushing in is not limited to the pliers 6, and any tool having a pushing function may be used. FIG. 6 shows a state in which the pushing-in state shown in FIG. 5 is further advanced and the elastic cover member 4 is put on a part of the string 1. The elastic cover member 4 is in a state where the string fixing portion is released from the swollen state and is fixed to the string 1 by an elastic force. FIG. 7 shows a state in which the state of FIG. 6 is further advanced and the elastic cover member 4 is entirely covered with the string 1.

  6 to 7, the elastic cover member 4 is pushed into the string 1, and at the same time, the string 1 moves away from the cover insertion member 3 while covering the elastic cover member 4. Since the elastic cover member 4 is aligned in advance with the end of the string 1, when the string 1 is pulled out from the hole 3 b of the cover insertion member 3 in the state of FIG. 7, the end of the elastic cover member 4 is Fits the end of the string. Since the string 1 has soft and fine irregularities, the elastic cover member 4 is firmly fixed to the string 1 with elastic force over the entire surface, and even if an external force acts in a direction to separate the string 1 from the elastic cover member 4, the elastic cover member There is no possibility that 4 will come off the string 1.

  Further, when the end portion of the elastic cover member 4 is slightly protruded from the end portion of the string, the end portion of the elastic cover member 4 can be contracted by the elastic force to cover the end portion of the string. In this way, the elastic cover member 4 is fixed to the string 1 at a stretch without the need for tying the string 1 or fraying the string 1. An example of this product is shown in FIG. If the elastic cover member 4 with a design such as letters is applied to the end of the string 1, the elastic cover member 4 can be fixed to the string 1 as an accessory member. Moreover, if a to-be-covered body is a string, it can apply to clothing, shoes, gloves, etc. Since the elastic cover member 4 is made of a soft material, it is easy to hold and helps prevent accidents such as injuries.

  FIGS. 11 to 15 show other product examples in the case of the string 1. FIG. 11 shows an example in which the elastic cover member 4 is fixed in the middle of the string 1. This is possible if the hole 3b of the cover insertion member 3 is deepened. FIG. 12 shows an example in which the ends of the two strings 1 are inserted and fixed in the holes 4 a of the elastic cover member 4. This can be fixed in the same manner as shown in FIG. 10 by inserting two ends of the string 1 in advance into the hole 3b of the cover insertion member 3 into which two strings can be inserted.

  FIG. 13 is an example in which FIG. 11 and FIG. 12 are combined, but is an example in which the end of the string 1 is bent and fixed. This is because when the elastic cover member 4 is pushed in after inserting the bent portion of the cord 1 into the hole 3b of the cover insertion member 3 in the form shown in FIG. The cover member 4 is fixed because it contracts due to the elastic force. FIG. 14 shows an example in which the string 1 is formed in a loop shape and both ends are fixed to both ends of the same elastic cover member 4.

  This fixing method is as follows. First, one end of the string 1 is fixed to the elastic cover member 4 in the same manner as in FIG. Next, the small-diameter portion 3d of the cover insertion member 3 is forcibly inserted into the hole 4a at the end of the elastic cover member 4 on the end portion side of the cord 1 (the portion where the cord is not threaded). The other end of the string 1 is inserted into the hole 3b of the cover insertion member in advance. When the elastic cover member 4 reaches the taper portion 3c and the large diameter portion 3a of the cover insertion member 3 by pushing, the other end portion of the string 1 starts to be fixed to the elastic cover member.

  Further pushing, the cover insertion member 3 is pulled away from the opposite end of the elastic cover member 4, and the cover insertion member 3 and the elastic cover member 4 are displaced relative to each other while holding the one string 1 end. One end is fixed and the state shown in the figure is obtained. FIG. 15 is an example applied to two strings 1. As long as the elastic force of the elastic cover member 8 can be maintained, the elastic cover member 8 can be simultaneously fixed to the plurality of strings 1.

  FIG. 16 is an example applied to the chain 7. Since the chain 7 has irregularities, the elastic force of the elastic cover member 4 functions effectively and can be firmly fixed. It goes without saying that the examples of FIGS. 11 to 15 are not limited to strings. Even a chain is applicable. FIG. 17 is an example applied when the body to be covered is a solid body, and shows a state where the elastic cover member 10 is fixed to the handle of the spoon 9. A soft feeling can be given to the touch when the spoon 9 is held, and the handle can be easily held and not slippery. Various designs can also be applied to the handle. FIG. 18 is an example in which the elastic cover member 12 is applied to the handle of the handle tool 11. Examples of this form are conventionally known, but can be firmly and easily fixed by applying the method of the present invention.

  The above example is an example in which an elastic cover member is directly covered on a covered body. However, a part of the covered body is processed or a member is provided, and the elastic cover member is fixed to the processed portion. May be. Next, an embodiment will be described. FIG. 19 is an example showing a resin part 4 a that is a fixing member that fixes the end of the string 1. The resin part 4a is a plate-shaped synthetic resin-made bending member provided with sharp irregularities on a sawtooth on the surface. The resin part 4a is placed on the bent string 1, and the concavo-convex part is bitten into the end of the string 1 and fixed, and in this state, the resin part 4a is inserted into the hole 3b of the large-diameter part 3a.

  FIG. 20 is an explanatory view showing a state where the resin part 4 a is fitted in the cover insertion member 3. Thereafter, the elastic cover member 4 is pushed into and fixed to the resin part 4a in the same manner as described above. The elastic cover member 4 wraps and covers the elastic cover member 4 and the string 1 portion with the concavo-convex portion and integrated with the resin part 4a. The number of the fixed portions of the string 1 is two in the figure, but may be one or plural. Further, if a hole is provided in the bent portion of the resin part 4a, the resin part 4a can be applied to a configuration in which the thin string 1a is separately provided. That is, if only the thin string 1a is passed through the hole and the normal string 1 is fixed to the elastic cover member 4 in the same manner as described above, the normal string 1 and the thin string 1a are formed in two string forms. The cover configuration can be realized.

  FIG. 21 shows such an example. As yet another example, a configuration in which a protruding protrusion 4b is provided at the bent portion is also possible. FIG. 22 shows a structure of an overhang body 4b in which a hole for passing the thin string 1a and the eaves member is provided in the protruding portion. The protrusion may be a wire. A bowl-like body may be used in addition to the hole, and the shape is not limited to a protruding shape. For example, as shown in FIG. 23, a string 1 having an elastic cover member 4 fixed and completed is used as a ring, and both ends are passed through holes by the projecting projecting bodies 4b, and butt-joined in the same configuration as a necklace. You can also Moreover, the thing of the structure which provides the thin string 1a separately is applicable to all the embodiment examples demonstrated below.

  The resin part 4c shown in FIG. 24 is a hard fixing member provided with sharp unevenness on the sawtooth on the surface. In the case of this example, the resin part 4c is sandwiched and fixed by the string 1. The figure shows this state. It is effective when applied to a flat and thin string 1. The uneven part of the resin part 4c bites into the string 1 and is fixed. The fixing method after fixing the resin part 4c between the strings 1 is the same as described above, and the resin part 4c is inserted into the hole 3b of the large-diameter portion 3a of the cover insertion member 3, and the elastic cover member 4 is covered and fixed. The uneven part of the resin part 4 c protrudes from the string 1 and bites into the elastic cover member 4. Although the number of fixing portions of the string 1 is two in the figure, it may be one or may be a plurality.

  FIG. 25 shows a state in which the fixing member is a ring-shaped ring part 4 d and the ring part 4 d is fixed to the string 1. This ring part 4d is provided with a hole, and the string end is tied after passing the string 1 through this hole. This string end may be solidified with a fixing material. The string 1 to which the ring part 4d is fixed is inserted into the hole 3b of the large-diameter portion 3a of the cover insertion member 3 in the same manner as described above, and the elastic cover member 4 is covered and fixed. When fixed, the elastic cover member 4 wraps and covers the entire ring part 4d. Accordingly, since the elastic cover member 4 is fixed to the string 1 while being caught by the ring par 4d, the elastic cover member 4 is a fixed product that does not come off the string 1.

  FIG. 26 shows a state where the elastic cover member 4 is fixed in the state of FIG. Although the elastic cover member 4 has various shapes, the shape in the figure is an example of a product of an elastic cover member designed with a hand. The string 1 is fixed to the ring part 4d while being buried in the elastic cover member 4. Further, the ring part 4d may be a cylindrical ring part 4e as shown in FIG. If the ring parts 4d and 4e have a shape shorter in length than the elastic cover member 4, the ring parts 4d and 4e are completely covered with the elastic cover member 4, and the fixing property is improved.

  The product example has been described in a specific shape. Further, although not shown in the drawing, in accordance with the above-described configuration, an immobilizing solution, paste, or a fixing agent kneaded with powder, etc. is dipped or applied to the end of the string to form irregularities, and dried and fixed to the fixing member. It is also possible to do it. Furthermore, although the above-mentioned embodiment demonstrated centering on applying to the edge part of a string, the thing of the structure which provides fixing members, such as a resin part and a ring part, in the middle part in the middle of a string, and attaches an elastic cover member Needless to say, this can also be applied.

  As described above, the elastic cover member fixing method and the apparatus thereof have been described on the assumption that the structure can be easily performed manually. However, in order to make the fixed state stable, one that can be operated with a dedicated device is better. In particular, when the number of products increases, the dedicated device improves the work efficiency, and the quality of the products is constant and stable. Next, an embodiment of the fixing device will be described.

(Technology and configuration related to push-in devices)
FIG. 28 to FIG. 31 show an example of a pushing device for pushing the elastic cover member 4 into a covered body such as the string 1. FIG. 28 is an overall front view of the pushing device 13, and FIG. 29 is a cross-sectional view showing the side thereof. 30 is a cross-sectional view taken along line AA in FIG. The base body is a frame body in which four plate members are formed in a mouth shape and attached to the base 14 with bolts. The pushing device 13 can be attached to any position via the base 14. This attachment may be fixed with a bolt, or may be fixed with a structure sandwiching the base 14.

  Two side plates 15 and 16 forming side walls are sandwiched between an upper plate 17 and a lower plate 18 and fixed with bolts. A screw 19 is rotatably provided between the two side plates 15 and 16. The moving member 20 meshes with the screw 19 and can move in the vertical direction as the screw 19 rotates. The moving member 20 is guided and moved by guide grooves 15 a and 16 a provided in the side plates 15 and 16. A bearing 21 is provided on the lower plate 18 and supports the lower end of the screw 19.

  A bearing 22 is also held on the upper plate 17 and supports the upper end of the screw 19. A retainer 23 is provided on the upper plate 17 and holds one end of the bearing 22. For this reason, the screw 19 does not shift in the axial direction. Further, the upper end of the screw 19 is configured such that the handle 24 can be inserted, and the screw 19 can be rotated by the handle 24. The upper plate 17 is provided with a position-adjustable stopper 25 and abuts against the moving member 20 to regulate the moving position of the moving member. Since the stopper 25 is a bolt, when the shapes of the elastic cover member 4 and the cover insertion member to be fixed are greatly different, the stopper 25 may be replaced with a suitable length.

  The moving member 20 has a U-shaped recessed portion 20a, and a holding member 26 for holding the cover insertion member 3 is provided in the recessed portion 20a. The holding member 26 is supported by a shaft body 27 supported by the moving member 20. The holding member 26 includes two pinching members 26a and a spring 26b. The two pinching members 26a can be rotated around the shaft body 27 by the elastic force of the spring 26b, and are normally biased in the contracting direction. However, it can be opened against the elastic force of the spring 26b as shown by a two-dot chain line.

The tip of the sandwiching member 26a is split so that a small-diameter shaft can be sandwiched from the lateral direction. A support plate 28 is attached to the lower plate 18 by bolts. The support plate 28 also has a slit configuration at the tip, and the small diameter portion 3d of the cover insertion member 3 can be inserted from the lateral direction. The cover insertion member 3 is set with the hook-shaped locking portion 3e positioned below the support plate 28. The support plate 28 and the holding member 26 can be exchanged depending on the form of the elastic cover member 4.
The configuration of the pushing device 13 has been described above. Next, the operation thereof will be described. As shown in FIG. 22, the screw 19 is rotated by the handle 24 and the holding member 26 is positioned adjacent to the support plate 28 in the lower position. Next, the small diameter portion 3 d of the cover insertion member 3 into which the elastic cover member 4 has been inserted in advance is inserted into the holding member 26 and the support plate 28. At this time, as described above, the hook-shaped locking portion 3e is positioned below the support plate 28.

  FIG. 31 shows this state. Subsequently, the screw 19 is rotated by operating the handle 24 to raise the holding member 26 while holding the elastic cover member 4. At this time, since the cover insertion member 3 is supported by the support plate 28 by the hook-shaped locking portion 3e, it is prevented that the cover insertion member 3 moves upward due to friction of the elastic cover member 4. When the holding member 26 rises and approaches the tapered portion 3c, the pinching member 26a gradually opens against the spring force. In this way, the pinching member 26a is pressed while pressing the elastic cover member 4 while forcibly compressing and inflating the elastic cover member 4 while being opened halfway, and is pushed into the covered body such as the string 1. When the elastic cover member 4 is all pushed in, the string 1 is separated from the cover insertion member 3.

  After the elastic cover member 4 is completely pushed into the string 1, the handle 24 is rotated in the reverse direction, and the holding member 26 is returned to the state shown in FIG. In this returning process, the cover insertion member 3 is displaced downward together with the holding member 26 while being held by the friction of the holding member 26. Therefore, a butting member 29 for preventing this is provided below the support plate 28. As a result, the small diameter portion 3d abuts against the abutting member 29 in the downward returning process, and the cover insertion member 3 maintains the state shown in FIG. When such pushing operation is completed, the next elastic cover member 4 is inserted into the cover insertion member 3, and the next target string is inserted into the hole 3b of the large diameter portion 3a, and the above-described operation is repeated.

  FIG. 32 shows a second embodiment for pushing the elastic cover member 4 into a covered body such as the string 1. The figure is a sectional view showing the entire side surface of the pushing device 30 of the second embodiment. The base 31 has a box shape, and the lower pedestal 31a can be fixed at an appropriate position on the work site. A part of the base 31 is an opening 31b, and a part of the base 31 is open to the outside. The holding member 32 is guided between the openings 31b and can move in the vertical direction. The holding member 32 is fixed to the rack body 33. When the rack body 33 is regulated and moved in the vertical direction along the opening 31b, the holding member 32 protruding from the opening 31b can move. Yes.

  The base body 31 above the rack body 33 is provided with a stopper 34 to restrict the upward movement of the rack body 33. The stopper 34 is a bolt. The stopper 34 is rotated by rotating the threaded portion, and is fixed to the base 31 by a nut 34a at a predetermined position. A gear 35 is rotatably incorporated in the base 31, and a pinion 36 is engaged with the gear 35. The pinion 36 is engaged with the rack 33 a of the rack body 33. Therefore, when the gear 35 rotates, the rack body 33 moves up and down via the pinion 36. A support gear 37 is provided below the rack body 33, and is used to appropriately support the posture of the rack body 33 or to fix the rack body 33.

  The support gear 37 may be a roll-shaped rotating body instead of a gear. A lever 39 is attached to the outside of the base 31 by being coupled to a rotary shaft 38 fixed to the gear 35. When the lever 39 is operated as indicated by an arrow and pushed downward, the gear 35 rotates and the rack body 33 moves upward as indicated by an arrow. When the lever 39 is operated in reverse, the rack body 33 moves downward.

  In this way, the holding member 32 can be moved in the vertical direction via the rack body 33. Although not shown, the gear 35 and the pinion 36 are supported on the side wall of the base 31 via bearings. Since the configuration of the holding member 32 is the same as that of the above-described embodiment, the description thereof is omitted. However, in the present embodiment, although shown in a simple configuration, the holding member 32 pushes the elastic cover member 4 into the string 1 via the cover insertion member 3 and fixes it. There is no change.

  A support plate 40 is provided at the lower portion of the base 31 as in the above-described embodiment, and the locking portion 3e and the small diameter portion 3d of the cover insertion member 3 are inserted. Since the function of this relationship is also the same as that of the above-mentioned embodiment, detailed explanation is omitted. Further, in the two embodiments, the holding member is moved and operated in the vertical direction, but it goes without saying that it may be in the horizontal direction.
