Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a plastic hook comprising a pair of male and female members that can be fitted to each other.
[0002]
[Prior art]
Hooks made of plastic, especially nylon, have been known for a long time and are used in various clothing items. A conventional nylon hook has several fitting pieces protruding toward the center of the cavity as disclosed in Japanese Utility Model Publication No. 61-136915, for example, as a female female hook. When the fitting piece is pushed by the male body for fitting, the fitting piece is elastically deformed in the male body pushing direction and allows the head of the male body to pass.
[0003]
In such a conventional nylon hook, since it is a spring that is pushed and bent in the pushing direction of the member (this is referred to as an upper and lower spring), the fitting piece of the female member contracts or extends due to the difference in temperature and humidity. There was a problem that it was affected and it became difficult to come off or loosen. Not only that, if the mating becomes tight during the dry season, it will not come off easily, and if it is accidentally pulled, it may tear the fabric.
[0004]
[Problems to be solved by the invention]
The present invention has been made paying attention to the above points, and an object of the present invention is to provide a plastic hook which is hardly affected by temperature and humidity and can always be stably fitted and separated. Another object of the present invention is to provide a plastic hook that can cope with increase and decrease of fitting and separating force. Moreover, the other subject of this invention is providing the thing which can be used as a hook.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the present invention provides a plurality of shaft-shaped springs that can contact a male member as a female member-fitting spring that can be fitted to a male member. spring, so as to elastically deform laterally with respect to the pushing direction of the male member by contact with the male member, which have a vertically elongated cross-sectional shape at least in part, shaft-like spring, during fitting Two are provided in parallel so as to sandwich the male member from both sides, and one or two protrusions that can be engaged with the male member are provided at both ends between the two shaft-like springs, The male member has a head having a larger diameter at the tip of the stud-like portion, and the head is provided on the same axis as the axis of the stud or protrudes to the side of the stud. in which took measures that the provided shall.
[0006]
The male member may have a so-called stud shape and a substantially the same configuration as a conventional male side having a swelling head at the upper end. The female member is provided with a fitting spring that can be fitted to the male member. In the present invention, the fitting spring includes a plurality of fitting springs provided in the fitting opening of the female member so as to be in contact with the male member. The fitting spring is a shaft-like spring. In the present invention, the term “shaft-like” refers to a spring having high rigidity that is not as soft as a conventional fitting piece.
[0007]
The shaft-shaped spring has a vertically long cross-sectional shape at least in part so that when the male member is pushed into the fitting port and comes into contact, it is elastically deformed laterally with respect to the pushing direction of the male member. . In other words, since the present invention is designed to be elastically deformed to the left and right sides with respect to the pushing direction of the male member, it is appropriate to refer to the left and right springs or the side springs relative to the conventional vertical spring. . The section shape is vertically long, which is a representation of the direction in which the push-in direction is standing upright, and the dimension in the cross-sectional shape is long and the dimension in the left-right direction is relatively short (see FIG. 2). Note that the cross-sectional shape other than a part thereof does not have to be vertically long.
[0008]
Since the rigidity is high and the cross-sectional shape is relatively long in the up-down direction and short in the left-right direction, it can be elastically deformed laterally against the pushing of the male member. Since it is a left and right spring instead of a vertical spring as in the past, there is little influence of shrinkage even in cold and dry periods, and the force required for unfitting slightly increases or decreases, but it shrinks and cannot be removed. Not.
[0009]
It is desirable that two axial springs be provided in parallel so that the male member is sandwiched from both sides when fitted. Due to the parallel arrangement, there is an advantage that the influence of temperature and humidity hardly reaches the distance between the springs. In this configuration, it is also desirable to provide protrusions that can engage with the male member at the end of the space between the two shaft-like springs. Since the projection can be engaged, the male member is unlikely to be detached in the direction of the axial spring with the projection, and the male member is likely to be detached in the direction crossing the direction of the axial spring not engaged with the projection. Although it occurs, it becomes possible to use this as a hook as well as a conventional mere hook by utilizing the directionality of the difficulty. The protrusions are provided on both sides and only on one side.
[0010]
Note that three or four shaft-like springs can be arranged so that the male member is sandwiched from three or four sides when fitted. When three shaft-shaped springs are provided, the fitting force tends to increase, so it is somewhat susceptible to temperature and humidity, but the size difference and the use of shirts, upper garments, etc. Is also convenient.
[0011]
Furthermore, an assembly of a large number of female members can be formed by disposing a plurality of female members on the substrate. A single base material may be provided with only one row of a plurality of female members. However, a plurality of rows may be provided. If two rows are provided in two rows, four rows and three in three rows are provided. One female member is used. By providing the plurality of female members in a plurality of rows, the female members are arranged stepwise in the direction of the row, and this has, for example, an adjustment function for selecting a hook stop position and adjusting the tightness. .
[0012]
The plastic hook of the present invention configured as described above is preferably made of nylon from the viewpoint of easy dyeing. However, other resins can be applied without considering dyeing, and for example, polypropylene resin (PP), copolymer polyacetal (for example, Duracon: trade name of Polyplastics), etc. can be used as the material.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of a plastic hook according to the present invention will be described in more detail with reference to the drawings. FIG. 1 shows a male member 11 of a plastic hook 10 as an example. The male member 11 has a stud 13 that stands upright on the mounting portion 12, and a swelling head 14 is provided at the upper end thereof. Since the male member 11 is for a single hook, an appropriate number of attachment holes 15 are provided in the attachment portion 12 and are sewn and stopped with a thread.
[0014]
In FIG. 2, the female member 16 is shown. The female member 16 has a fitting port 19 and has two shaft-like springs 17 and 18 provided in parallel with a gap sandwiching the male member 11 from both sides. The two axial springs 17 and 18 are provided at intervals that can contact the stud 13 of the male member 11, and as a whole, have a vertically long cross-sectional shape with respect to the pushing direction of the male member 11 ( FIG. 2 (b)). Spaces 21 and 22 are prepared outside the shaft-shaped springs 17 and 18 so that each can be elastically deformed outward.
[0015]
Further, the shaft-like springs 17 and 18 communicate with the female member main body through inclined portions 17m, 17n, 18m, and 18n at both ends (see FIGS. 2 and 3B). The inclined portions 17m, 17n, 18m, and 18n are more difficult to deform and the intermediate portion is more easily deformed, so that the male member 11 can be pushed and removed more easily.
[0016]
Protrusions 23 and 24 that can be engaged with the male member 11 are provided at both ends of the space between the two axial springs 17 and 18. The protrusions 23 and 24 pass through the expansion head 14 of the male member 11 without difficulty. However, the protrusions 23 and 24 are provided at intervals such that the male member 11 is not easily engaged and pulled out when the male member 11 is inclined. 25 is a female member back side recessed part, When the male member 11 is fitted, the swelling head side will be located. Reference numeral 26 denotes a mounting hole for the female member 16, and 27 denotes a recess for thread escape.
[0017]
The state in which the male member 11 and the female member 16 are fitted is shown in FIGS. 3 (a), 4 (a) and 4 (b). When the male member 11 is pushed into the fitting port 19, when the expansion head 14 passes between the shaft-like springs 17 and 18 in the fitting port, the shaft-like springs 17 and 18 are elastically deformed to the maximum (FIG. 3 ( When the swollen head 14 comes out to the concave portion 25 side, a fitting state is established (FIG. 4). As shown in FIG. 4B, the stud 13 can be in contact with the shaft-shaped springs 17 and 18, but the removal is easy as long as the elastic deformation of the shaft-shaped springs 17 and 18 can be used when the expansion head 14 is extracted. is there. However, if the male member 11 is tilted in a direction in which it is difficult to use the elastic deformation of the shaft-like springs 17 and 18, the protrusions 23 and 24 engage with the expansion head 14 and are difficult to remove.
[0018]
FIG. 5 shows a female member 16 ′ of a modification of Example 1 of the plastic hook according to the present invention, which exhibits a stronger spring force than that of Example 1. Although the shaft-like springs 17 'and 18' of this modification have the same vertical and horizontal ratio as the shaft-like springs 17 and 18 of Example 1 at the central portion, the lateral dimensions at both ends are widened to widen the wide portion 17. ", 18". The widening portion is designed to increase by 25% of the size of Example 1, and has obtained good results, but this number is illustrative and not limiting. As a result of the provision of the wide portions 17 ″ and 18 ″, stepped portions 17a and 18a are formed in the fitting port 19. The stepped portions 17a and 18a are engaged and come out when the male member 11 is inclined. It works to be difficult. The strong hook according to this modified example can be said to be a strong hook that exhibits a detachable force suitable for jumpers and work clothes when the one in Example 1 has a detachable force suitable for shirts and blouses.
[0019]
FIG. 6 and subsequent figures show Example 2 of a plastic hook comprising a plurality of female members and male members. 7 (a) and 7 (b) show a female member assembly 46 integrally provided by disposing a plurality of female members 44 on a base material 45, and FIGS. 7 (c) and 7 (d) show a male member 47. A plurality of male member assemblies 49 provided integrally by being disposed on the base material 48 are shown. The specific configurations of the female member 44 and the male member 47 may be the same as those of Example 1 shown in FIGS. 1 to 4, and the male member assembly 46 and the female member assembly 49 can be fitted and removed from each other. It is.
[0020]
In the female member assembly 46 of Example 2 , the female members 44 are arranged in the direction of the axial springs 17 and 18. However, the present invention is not limited to this, and the female members 44 can be arranged in a direction orthogonal to the above direction, and the ease of removal varies depending on which direction is taken. For FIG. 6 (a), the easily removable in the vertical direction in the drawing but becomes difficult to remove the left-right direction.
[0021]
FIG. 7 shows Example 3 in which three rows of base members 52 having three female members 51 arranged in one row are arranged to form a female member assembly 53 consisting of a total of nine female members 51. On the other hand, the male member 54 is a combination of male member assemblies 56 in which three rows are arranged on the base 55. Reference numeral 57 denotes a connection portion for connection at 52 parts of the base material. The female member 51, since the shaft-shaped spring direction are arranged in multiple rows, unlike the example of FIG. 6, difficult to remove in a vertical direction in FIG. Therefore, by attaching the plastic hook of the present invention to the end of the band or belt, the belt tightening degree can be adjusted in three stages, and when the male member assembly 56 is removed, the external force in the fitting port direction be added to, but can be detached male member 54 easily from the female member 51, fitting direction intersecting the abutment, that is the vertical direction of the external force of the female member in parallel with the substrate surface of the aggregate and FIGS. 7 (a) By arranging the female member assembly 53 and the male member assembly 56 so as to be applied, the external force accompanying the belt tension cannot be removed. Therefore, the plastic hook of the present invention can be used as a substitute for a hook, and its use and function are flexible. The specific configurations of the female member 51 and the male member 54 are illustrated as being the same as those of Example 1.
[0022]
FIG. 8 and subsequent figures show Example 4 in which the performance for using the present invention as a hook is improved. The female member 61 shown in FIG. 8 has a short cylindrical outer frame, and only one of the insides protrudes. 66, the other is removed, and the fitting port 19 is widened on the removal side, and wide portions 62, 63 are provided so that the male member 63 can be inserted and removed with almost no resistance. The wide portion 62 is the male member 67. When it is fitted, it is caught by the projection 66 so as not to come out. In addition, since the strength of the axial springs 64 and 65 is weakened by the enlarged portions 62 and 63 having a vertically long cross-sectional shape, it is easy to come off even if the head 68 of the male member 67 is caught. The head 68 at the tip of the stud of the male member 67 is provided so as to protrude to one side (FIGS. 9D and 9E) so that it is sufficiently caught by the protrusion 66 of the female member 61 at the portion where the heel is deeply shown. Designed. Since the other points may be the same as those in Example 1, reference numerals are used.
[0023]
The female member assembly 70 shown in FIGS. 9 (a) and 9 (b) is a two-stage arrangement of two hook-type female members 61 shown in Example 4 arranged in the same direction on the base material 71. This is Example 5 in which the aggregate has a total of four female members 61. For this reason, the position where the male member assembly 72 in which two male members 67 are arranged on the base material 73 is hooked can be adjusted in two stages, and the male member 67 is almost inserted and removed by the wide portions 62 and 63. The feature is that it can be attached and removed without resistance. Reference numeral 69 denotes a connecting portion provided between the base material portions. Therefore, in the case of Example 4 and Example 5 , the male member 67 or the female member 61 of the male member assembly 72 or the female member 61 or the member assembly 70 of the male member assembly 72 can be removably attached. .
[0024]
Therefore, the plastic hook of the present invention can be used as a clothing hook in the same manner as a conventional metal hook, and can also be used as a substitute for a metal hook used in women's underwear, for example. is there. When the plastic hook of the present invention is made of nylon, since it is easily dyed, color matching with clothing is easy, and an aesthetic effect can be obtained in comparison with a cold conventional metal hook.
[0025]
【The invention's effect】
Since the present invention is configured and operates as described above, it does not come out due to changes in temperature and humidity, or on the contrary, it is not too loose to rely on, and always has stable fitting and separation properties. In addition, when a protrusion that can be engaged with the female member and the male member is provided, the separation of the fitted female member changes depending on the direction, and multiple rows of female members are provided for tightening. It has a remarkable effect such as being equipped with an adjusting function.
