Description

  The present invention relates to a roll screen capable of moving a screen up and down.

  The roll screen supports the winding pipe by a frame (for example, a mounting frame) attached to the mounting surface such as a ceiling surface or a wall surface via a bracket, and attaches the upper edge of the screen to the winding pipe. Then, the amount of light collected into the room can be adjusted by winding or unwinding the screen with a winding pipe.

  In a general roll screen, support members (side brackets) are fixed to both ends of the mounting frame, and a cylindrical winding pipe is rotatably supported between the left and right support members.

  Such a support member (side bracket) has a fixed shaft member (bracket shaft) that pivotally supports one end of the take-up pipe, and a base member (side bracket base) that fixes and supports the fixed shaft member. In many of the conventional roll screens, a technique for fixing the fixed shaft member to the base member by screwing or riveting is used (see, for example, Patent Documents 1 and 2).

  In the roll screen 1 shown in FIG. 1, support members 2 a and 2 b are fixed to both ends of the mounting frame 2, and a fixed shaft member 9 is fixed to the support members 2 a and 2 b. By the fixed shaft member 9, the cylindrical winding pipe 3 is rotatably supported between the support members 2a and 2b. The bracket 6 is used when the mounting frame 2 is indirectly fixed to the attachment surface. Each support member 2 a and 2 b is accommodated by the side cover 10.

  An operation pulley 11 is provided at the right end of the winding pipe 3, and an endless operation cord 7 hung around the operation pulley 11 is suspended. In this example, the operation cord 7 is configured by a ball chain, and the surface of the operation pulley 11 around which the ball chain is hung is configured to have irregularities that are shaped to fit the ball portion of the ball chain. . The winding pipe 3 can be rotated by operating the operation cord 7. The operation cord 7 may be formed in a string shape, and the surface of the operation pulley 11 around which the operation cord 7 is wound may have a highly frictional surface shape.

  The winding pipe 3 is attached to one end of the screen 4 and supports the screen 4 so that the screen 4 can be wound or unwound. The other end of the screen 4 is attached to a weight bar 5 that functions as a weight member. Accordingly, the screen 4 is stretched based on the weight of the weight bar 5. In the example of this embodiment, the screen 4 is suspended from the outdoor side of the winding pipe 3.

  When the operation cord 7 is operated to rotate the winding pipe 3 in the screen winding direction, the weight bar 5 is raised, and when the winding pipe 3 is rotated in the screen unwinding direction, the weight bar 5 is lowered.

  Further, in the take-up pipe 3, a spring motor for reducing the operating force when the screen 4 is wound is housed on the left end side, and a stopper device for preventing the weight of the screen 4 from falling down is housed on the right end side. Not shown).

(Configuration around the support member)
FIG. 2 is a perspective view showing a configuration around the support member 2a (base member 8 and fixed shaft member 9) in the roll screen 1 according to the embodiment of the present invention. In the example of the fixed shaft member 9 illustrated in FIG. 2, a shape having a cylindrical shaft-shaped shaft portion 9 a for supporting each end portion in the left-right direction of the winding pipe 3 and a flange 9 b is illustrated.

It may be formed, and the shape of the shaft portion 9a according to the application can be appropriately set.

  By the way, as shown in FIG. 2, the support member 2a is the same as the support member 2b, but the attachment screw 200 is inserted into the attachment hole 801 provided above the base member 8, and this sufficient length of attachment is provided. The screw 200 is fixed to the mounting frame 2 by being screwed into each end of a plurality of screw receiving portions 202 extending in the left-right direction of the mounting frame 2.

  On the other hand, the support member 2a (or 2b) comprising the fixed shaft member 9 and the base member 8 according to the present invention will be described in detail later, and stable fixation is ensured without mainly using screws, rivets or nuts. In addition, the peripheral configuration (width w) of the fixed shaft member 9 can be reduced in size. Furthermore, the support member 2a (or 2b) maintains the flatness of the side surface opposite to the surface on which the fixed shaft member 9 is fixed (the outer surface of the base member 8 in the left-right direction), so that the storage by the side cover 10 is stable. Is secured.

  The support members 2a and 2b are both configured in the same manner. Hereinafter, the configuration of the support member 2a will be described as a representative.

(Basic concept of support member)
3A and 3B are a partial front view and a side view showing the basic concept of the support member 2a (base member 8 and fixed shaft member 9) according to the present invention, respectively.

  In the conventional technique, as described above, the base member 8 and the fixed shaft member 9 are fixed with screws. However, due to the nature of the screws, there is a risk of assembly errors (insufficient torque, slanting, fastening leakage). is there.

  In order to solve this problem, the support member 2a (the base member 8 and the fixed shaft member 9) according to the present invention does not use a screw for fixing the base member 8 and the fixed shaft member 9, or even if it is used, it is auxiliary fixed. (Even if the screw is loosened, it is fixed to maintain the fit within the range of possible misuse) and after the product is delivered (after the roll screen 1 is installed), the range of misuse that is expected in advance (unpredictable misuse) And holding means (a fitting structure or a holding structure) that cannot be disengaged in the use of any operation.

  More specifically, with reference to FIGS. 3A and 3B, the holding means 8a and 8b for fixing the base member 8 and the fixed shaft member 9 will be described.

  The fixed shaft member 9 is fixed to the base member 8 to constitute the support member 2a. However, in order to prevent the fixed shaft member 9 from being detached from the base member 8 in the direction of the broken line arrow shown in FIG. As shown in FIGS. 3A and 3B, the member 8 is provided with holding means 8a and 8b.

  As shown in FIG. 3B, the holding means 8a holds the flange 9b of the fixed shaft member 9 in order to prevent the Y-axis direction from coming off.

  As shown in FIG. 3B, the holding means 8b holds the shaft portion 9a of the fixed shaft member 9 in order to prevent the retaining shaft 8b from coming off in the illustrated Z-axis direction.

  That is, the support member 2a according to the present invention is prevented from coming off in the Y-axis direction and Z-axis direction shown in FIG. 3B (fixed to the base member 8 in a direction perpendicular to the axial direction of the fixed shaft member 9). By configuring the shaft member 9 to have a function of preventing the shaft member 9 from being detached, the holding means 8a and 8b cooperate to disengage the fixed shaft member 9 from the base member 8 in the direction of the broken arrow shown in FIG. Is to prevent.

  As described above, the holding means 8a and 8b for preventing the fixed shaft member 9 from being detached from the base member 8 in cooperation with the base member 8 and the fixed shaft member 9 are the support members 2a ( This is realized by a fitting structure or a holding structure in the base member 8 and the fixed shaft member 9).

  Hereinafter, the support member 2a (base member 8 and fixed shaft member 9) of each embodiment will be described in detail.

(Support member of Example 1: rotation fitting)
FIG. 4A is a perspective view showing the configuration of the support member 2a (base member 8 and fixed shaft member 9) of Example 1 according to the present invention, and FIG. 4B is an assembly method (rotation). FIG. 4C is a cross-sectional view for explaining the assembly method. Similar components are denoted by the same reference numerals.

  The support member 2a according to the first embodiment illustrated in FIG. 4 includes a holding unit configured to fix the base member 8 and the fixed shaft member 9 by rotational fitting.

  First, as shown in FIG. 4A, the base member 8 is made of a metal material, and is formed by a cutting process in which a substantially T-shaped plate-like piece 81 is cut out from the cut-out portion 811 and bent by approximately 90 °. . A pair of protrusions 81 a are formed at the tip of the plate-like piece 81 as shown in the figure.

  On the other hand, the fixed shaft member 9 is made of a synthetic resin material, has a shaft portion 9a and a flange 9b, and has a hollow portion 91 that opens in a round hole shape from a substantially central portion of the flange 9b toward the inside of the shaft portion 9a. Provided. The hollow portion 91 is formed with a pair of insertion guide grooves 91a and a locking groove 91b which is continuous at the innermost part of each insertion guide groove 91a and bends approximately 90 ° in the same circumferential direction of the shaft portion 9a.

  The pair of insertion guide grooves 91 a in the fixed shaft member 9 are engaged with a pair of protrusions 81 a formed at the tip of the plate-like piece 81 in the base member 8 to guide the insertion of the plate-like piece 81. Then, at a position where the surface of the flange 9b and the surface of the base member 8 come into contact with each other, the pair of protrusions 81a are rotationally guided by the locking grooves 91b (see FIG. 4C).

  Therefore, as shown in FIG. 4B, through the insertion operation (step S <b> 1) of inserting the plate-like piece 81 of the base member 8 into the hollow portion 91 of the fixed shaft member 9, the surface of the flange 9 b and the base member 8. The base member 8 and the fixed shaft member 9 can be fixed to each other by rotational fitting in which a rotation operation (step S2) is performed to rotate the fixed shaft member 9 by approximately 90 ° at a position where the surfaces abut.

  Here, it is preferable that the pair of protrusions 81a be configured to be tightly pressed against the locking groove 91b and to be configured to increase the locking force due to the rotation fitting, but the configuration is not necessarily limited to the pressure. That is, after the roll screen 1 is assembled, even if a force acts in the direction in which the fixed shaft member 9 rotates with respect to the base member 8 and the relative rotation rotates, the deterring force with respect to the disengagement direction as shown in FIG. Is to work.

  In the example shown in FIG. 4, an example in which no screws, rivets, or nuts are used for fixing the fixed shaft member 9 and the base member 8 is shown. Also good.

  As described above, the support member 2a according to the first embodiment is configured to reliably fix the fixed shaft member 9 to the base member 8 without mainly using screws, rivets, or nuts, and constitute a highly reliable roll screen 1. Can do.

(Supporting member of Example 2: Push-fit)
FIG. 5 (a) is a perspective view showing the configuration of the support member 2a (base member 8 and fixed shaft member 9) of Example 2 according to the present invention, and FIG. 5 (b) shows its assembly method (push-in). FIG. 5C is a cross-sectional view for explaining the assembly method. Similar components are denoted by the same reference numerals.

  The support member 2a according to the second embodiment illustrated in FIG. 5 includes a holding unit configured to fix the base member 8 and the fixed shaft member 9 by pressing and fitting.

  First, as shown in FIG. 5A, the base member 8 is made of a metal material, and is formed by a cutting process in which a substantially square plate-like piece 82 is cut out from the cutout portion 821 and bent at about 90 °. A fitting hole 82a is formed near the tip of the plate-like piece 82 as shown in the figure.

  On the other hand, the fixed shaft member 9 is made of a synthetic resin material, has a shaft portion 9a and a flange 9b, and has a hollow portion 92 that opens in a square hole shape from a substantially central portion of the flange 9b to the inside of the shaft portion 9a. Provided. A pair of insertion guide grooves 92a is provided in the upper portion of the hollow portion 92, and therefore the hollow portion 92 is T-shaped when viewed from the surface of the flange 9b. A projection 922 is formed between the pair of insertion guide grooves 92a so as to slightly protrude downward from the upper portion of the hollow portion 92. A protruding piece 921 that protrudes in the axial direction from the surface of the flange 9 b is formed at a position corresponding to the lower portion of the pair of insertion guide grooves 92 a in the hollow portion 92 with a thickness equal to or less than the thickness of the base member 8.

  In the illustrated example of the base member 8, although not necessarily provided, as a preferred example, two engagement receiving portions 822 are provided so as to sandwich the plate-like piece 82. Further, in the example of the fixed shaft member 9 shown in the figure, two engaging protrusions 923 are formed so as to sandwich the hollow portion 92 and the protruding piece 921. In this case, the two engaging protrusions 923 in the fixed shaft member 9 are engaged and positioned with the engagement receiving portions 822 in the base member 8, respectively, and the relative rotation between the fixed shaft member 9 and the base member 8 is further suppressed. Can be made.

  The pair of insertion guide grooves 92 a in the fixed shaft member 9 are engaged with respective end portions of the base member 8 in the width direction of the plate-like piece 82 to guide the insertion of the plate-like piece 82. Then, at the position where the surface of the flange 9b and the surface of the base member 8 abut, the protruding piece 921 is engaged with the cutout portion 821, and the protruding portion 922 is fitted into the fitting hole 82a (FIG. 5 (c)).

  Therefore, as shown in FIG. 5 (b), the push-in fitting that performs the insertion operation (step S1) for inserting the plate-like piece 81 of the base member 8 into the pair of insertion guide grooves 92a in the hollow portion 92 of the fixed shaft member 9 is performed. Thus, the base member 8 and the fixed shaft member 9 can be fixed to each other.

  In the example shown in FIG. 5, after the roll screen 1 is assembled, not only the deterrence force against the detachment direction as shown in FIG. 3A works but also the force in the direction in which the fixed shaft member 9 rotates with respect to the base member 8. Even if it works, it does not rotate relative.

  The example shown in FIG. 5 also shows an example in which no screws, rivets, or nuts are used for fixing the fixed shaft member 9 and the base member 8, but screws or the like are used for auxiliary fixing. It is good also as a structure to use.

  As described above, the support member 2a according to the second embodiment constitutes the highly reliable roll screen 1 by reliably fixing the fixed shaft member 9 to the base member 8 without mainly using screws, rivets, or nuts. Can do.

(Support member of Example 3: Push-fit)
FIG. 6A is a perspective view showing the configuration of the support member 2a (base member 8 and fixed shaft member 9) of Example 3 according to the present invention, and FIG. 6B is an assembling method (push-in). It is sectional drawing for demonstrating fitting. Similar components are denoted by the same reference numerals.

  The support member 2a according to the third embodiment shown in FIG. 6 includes a holding unit configured to fix the base member 8 and the fixed shaft member 9 by another push-in fitting.

  First, as shown in FIG. 6A, the base member 8 is made of a metal material, and is formed by a cutting process in which a substantially T-shaped plate-like piece 83 is cut out from the cut-out portion 831 and bent approximately 90 °. . As shown in the figure, a pair of protrusions 83 a is formed at the tip of the plate-like piece 83. In the example of the base member 8 shown in the drawing, although not necessarily provided, the two engaging projections 832 are provided so as to sandwich the plate-like piece 83, and an auxiliary hole 833 is provided above the plate-like piece 83. ing. Such engagement protrusions 832 and auxiliary holes 833 may be provided for the base member 8 in the first and second embodiments described above or the embodiments described later.

  On the other hand, the fixed shaft member 9 is made of a synthetic resin material, has a shaft portion 9a and a flange 9b, and a raised surface 932 having a predetermined thickness is formed on the surface of the flange 9b.

  A hollow portion 93 that opens in a square hole shape from a substantially central portion of the raised surface 932 toward the inside of the shaft portion 9a is provided. A pair of fitting holes 93 a are formed in the innermost part of the hollow portion 93. In addition, a total of four elastic deformation assisting grooves 931 are provided above and below the hollow portion 93, so that the hollow portion 93 is urged to elastically deform in an arbitrary direction. In the example of the fixed shaft member 9 shown in the figure, although not necessarily provided, the two engagement receiving portions 933 are formed so as to sandwich the hollow portion 93, and the auxiliary groove 934 is formed above the hollow portion 93. Yes. Such a raised surface 932 may be provided for the fixed shaft member 9 in the first and second embodiments described above or the embodiments described later.

  The hollow portion 93 in the fixed shaft member 9 is elastically deformed while narrowly pressing the pair of protrusions 83a of the plate-like piece 83 in the base member 8, and guides the insertion of the plate-like piece 83. The pair of fitting holes 93a in the innermost part of the hollow portion 93 are fitted into the pair of protrusions 83a of the plate-like piece 83 at the position where the side surface of the raised surface 932 of the flange 9b contacts the surface of the base member 8, respectively. (See FIG. 6B).

  When the pair of fitting holes 93a are respectively fitted into the pair of protrusions 83a, the two engagement receiving portions 933 of the fixed shaft member 9 are respectively engaged and positioned with the engagement protrusions 832 of the base member 8. (See FIG. 6 (b)).

  At this time, since the positions of the auxiliary groove 934 in the fixed shaft member 9 and the auxiliary hole 833 in the base member 8 are aligned, for example, the relative rotational position with respect to the winding pipe 3 is adjusted from the auxiliary hole 833 toward the auxiliary groove 934. A lock pin (not shown) for locking may be provided. The function of adjusting the relative rotational position with respect to the take-up pipe 3 is not directly related to the present invention, and further details are omitted.

  Therefore, as shown in FIG. 6B, the base member 8 and the fixed member are fixed by a push-in fitting for inserting the plate-like piece 83 of the base member 8 through the hollow portion 93 of the fixed shaft member 9 (step S <b> 1). The shaft members 9 can be fixed to each other.

  In the example shown in FIG. 6, after the roll screen 1 is assembled, not only a deterring force against the disengagement direction as shown in FIG. 3A acts but also a force in a direction in which the fixed shaft member 9 rotates with respect to the base member 8. Even if it works, it does not rotate relative.

  The example shown in FIG. 6 also shows an example in which no screws, rivets or nuts are used for fixing the fixed shaft member 9 and the base member 8, but screws or the like are used for auxiliary fixing. It is good also as a structure to use.

  As described above, the support member 2a according to the third embodiment constitutes the highly reliable roll screen 1 by reliably fixing the fixed shaft member 9 to the base member 8 without mainly using screws, rivets, or nuts. Can do.

(Support member of Example 4: press-fitting)
FIG. 7A is a perspective view showing the configuration of the support member 2a (base member 8 and fixed shaft member 9) of Example 4 according to the present invention, and FIG. FIG. 7C is a cross-sectional view for explaining the assembly method. Similar components are denoted by the same reference numerals.

  The support member 2a according to the fourth embodiment shown in FIG. 7 has holding means configured to fix the base member 8 and the fixed shaft member 9 by pressing and pressing.

  First, as shown in FIG. 5A, the base member 8 is made of a metal material, and a cylindrical throttle portion 84 squeezed into a cylindrical shape is formed.

  On the other hand, the fixed shaft member 9 is made of a synthetic resin material, has a shaft portion 9a and a flange 9b, and has a hollow portion 94 that opens from a substantially central portion of the flange 9b in a round hole shape and toward the inside of the shaft portion 9a. Provided. On the upper part of the hollow portion 94, a single protrusion (or a plurality of protrusions) 94a is provided. The diameter of the hollow portion 94 is substantially equal to the outer diameter of the cylindrical throttle portion 84.

  In the illustrated example of the base member 8, although not necessarily provided, as a preferred example, two engagement receiving portions 841 are provided so as to sandwich the cylindrical diaphragm portion 84. Further, in the example of the fixed shaft member 9 shown in the figure, two engaging projections 941 are formed so as to sandwich the hollow portion 94. In this case, the two engaging protrusions 941 in the fixed shaft member 9 are respectively engaged and positioned with the engagement receiving portions 841 in the base member 8, and the relative rotation between the fixed shaft member 9 and the base member 8 is suppressed. Can do.

  The hollow portion 94 in the fixed shaft member 9 engages with the cylindrical throttle portion 84 in the base member 8 and guides its insertion. However, since the hollow portion 94 is provided with the convex portion 94a, the insertion of the cylindrical throttle portion 84 into the hollow portion 94 is narrowed and press-fitted. And it press-fits to the position which the surface of the flange 9b and the surface of the base member 8 contact | abut (refer FIG.7 (c)). FIG. 7C shows an example in which the convex portion 94a is arranged at an arbitrary position and the fixed shaft member 9 is pushed into the base member 8 to facilitate understanding of the present invention.

  Accordingly, as shown in FIG. 7B, the base member 8 and the fixed shaft are fixed by the press-fitting operation (step S1) in which the cylindrical throttle portion 84 of the base member 8 is pushed into the hollow portion 94 of the fixed shaft member 9. The members 9 can be fixed to each other.
