Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a joint frame such as a curtain box frame, and more particularly to a joint frame formed integrally by connecting a plurality of frame members via elastic holding fittings.

(Prior Art) Generally, a box frame for accommodating and suspending curtains, blinds, lighting equipment, etc. has a top wall section for suspending objects to be hung, such as curtains, and a hanging wall section hanging from both ends of the top wall section. It is formed into a U-shaped or L-shaped cross section that opens downward, or a frame is provided protruding from one side end of the top wall part to the outside of the lower end of the hanging wall part.
Since such a box frame has various variations in the size of the suspended object, if it is formed as an integral frame in advance, many types of box frames must be prepared. In addition, for example, when a box frame is constructed from an extruded aluminum material, it is difficult to mold a large box frame by extrusion. Recently, therefore, these box frames have been formed in advance by dividing them into a top wall member, a hanging wall member, a frame member, etc., and these frame members are connected to each other. Although this method has fewer parts for each frame member, it is possible to assemble and form many types of box frames by combining them, and since molding is easy, it is possible to lower material costs, and
Packing and shipping costs are easy. However, on the other hand, the joint frame formed by connecting the frame members in this way involves tying work. Conventionally, the ends of the assembled members were overlapped and the overlapped parts were connected using screws, which took time to fasten.As a result, although the material cost was low, the construction cost was high, resulting in an overall Costs could not necessarily be kept low.

(Objective of the invention) The object of the present invention is to solve the above-mentioned drawbacks, and particularly to propose a joint frame in which frame members are easily and reliably connected without using screws.

(Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1a and 1b, the symbol A indicates a curtain,
A box frame that also serves as a blind, and the box frame A
is the base frame member 1 that constitutes the ceiling wall part and the upper part of the hanging wall part.
A joint frame formed by connecting a hanging wall member 2 constituting the lower part of the hanging wall portion to the lower part of the base frame member 1 through a holding fitting 3.
is made of a metal section having a U-shaped cross section, and is provided with a curtain rail a on the lower surface of the ceiling wall portion, and a connecting groove 4 that opens inwardly at the middle portions of both sides. A constricted portion 5 is formed inside the connecting groove 4 .

The hanging wall member 2 constituting the lower part of the hanging wall portion is also made of a metal member, and has a hook-shaped ridge 10 at the upper end, and a connecting edge 6 is protruded outward from the tip of the ridge 10. . The connecting edge 6 is set to fit loosely into the connecting groove 4, and has a bulge 7 formed at its tip. In addition, a shallow engagement groove 11 that opens upward is formed in the middle part of the hanging wall member 2.
A guide surface 12 is provided on the outside of the engagement groove 11. The lower end of the hanging wall member 2 is bent outward.

Next, the holding fitting 3 is made of an elastic metal,
It is formed by protruding an outer engaging piece 15 and inner engaging pieces 16 and 17 from a base piece 14 whose central part is bent into a U shape. Projecting and inner engaging pieces 16, 17
The tip also faces toward the tip and protrudes in a tapered shape.

As shown in FIG. 2a, the holding fitting 3 is made by making a U-shaped notch in the surface of the U-shaped base piece 14, and raising the inside of this notch inward or outward to connect the outer engaging piece 15 and the inner engaging piece. Alternatively, as shown in FIG. 2b, a cut may be made on the outer side of the U-shaped base piece 14, and the cut may be bent inward or outward to form the outer engaging piece 15. and an inner engagement piece 16,
17 may be formed.

When connecting the base frame member 1 and hanging wall member 2 to form a hanging wall, first, connect the connecting groove 4 of the base frame member 1.
Alternatively, the holding fittings 3 are fitted and attached at regular intervals along the longitudinal direction of the connecting edge 6 of the hanging wall member 2, and then attached to the vicinity of both lower ends of the base frame member 1 and the upper end of the hanging wall member 2. The lower ends of both sides of the base frame member 1 are engaged with the engagement grooves 11 of the hanging wall member 2, and the connecting edge 6 is fitted inside the holding fitting 3 in the connecting groove 4. The outer engaging piece 15 of the holding fitting 3 engages with the inner wall of the constricted parts 5, 5 in the connecting groove 4, and the inner engaging piece 17 engages with the base of the distal end protrusion 7 of the connecting edge 6. The connecting edge 6 of the hanging wall member 2 is held in the connecting groove 4 of the base frame member 2 via the holding fitting 3, and the hanging wall member 2 and the base frame member 2 are reliably connected.

Note that the connecting portions 40, 40 formed by the connecting portions 4 and the connecting edges 6 formed on the two frame members on each side of the hanging wall portion protrude so as to face the inside of the hanging wall portion. It is formed.

In the above connection configuration, when some force is applied to the hanging wall member 2 from the inside to the outside, the hanging wall member 2 rotates outward, and at this time, the connecting edge 6 tends to come out of the connecting groove 4. do. However, the rotation of the hanging wall member 2 is centered around the engagement portion between the engagement groove 11 and the tip of the base frame member 1, and the radius is the overlapping portion 41 of the base frame member 1 and the hanging wall member 2. Since it is a rotation and the rotation radius is large, the connection edge 6
The angle within the connecting groove 4 does not change much.
Therefore, since the holding fitting 3 does not move much, the engagement with the connecting edge 6 and the connecting groove 4 is maintained stably, and there is no fear that the connecting edge 6 will come off.

On the other hand, when there is no overlap between the base frame member 1 and the hanging wall member 2, the connecting edge 6 rotates at a small radius, so the pulling out force of the connecting edge 6 increases due to the lever principle, and Since the holding fitting 3 moves and deforms greatly within the groove 4, the holding fitting 3 and the connecting groove 4 or the connecting edge 6 are likely to disengage, which is extremely dangerous.

Next, when installing the box frame A having the joint frame configuration described above to the corner between the ceiling D and the wall E, first place the box frame A at a certain interval from the top of the ceiling D along the corner. A hanging fixture 9 may be attached to the hanging support fixture 8, and the box frame A may be mounted via the hanging fixture 9. In this case, a male threaded portion 8a is provided at the tip of the support fitting 8.
and nuts 18, 18 that are screwed into the male threaded portion.
With the hanging tool 9 sandwiched between them, the protruding locking parts 9a, 9a at the lower end of the hanging tool 9 are inserted into the fitting grooves 1a, 1a at the upper part of the box frame A, and fitted by snap locking or the like. At the same time, the hanging tool 9 is adjusted and moved left and right along the elongated hole 19, and the nuts 18, 18 are tightened. Although the hanging tool 9 is fixed, the fitting groove 1
The box frame A can be adjusted in the longitudinal direction by sliding the parts a and 1a along the protruding locking parts 9a and 9a.

A curtain rail a is formed on the box frame A, and a connecting portion 40 is formed by a connecting groove 4 and a connecting edge 6 formed in the two frame members on each side of the hanging wall. 40 is formed to protrude so as to face the inner side of the hanging wall portion. Since both ends b1, b1 of the hanging tool of the blind hanging tool b (or lighting equipment, etc.) can be locked to the upper surfaces of these connecting parts 40, 40, it is possible to select either one according to the conditions of the site. can.

A joint plate 22 is fitted into a joint plate fitting groove 21 formed on the lower side of the box frame A, and is aligned and connected to the adjacent box frame. Further, in a normal case, one lower end of the box frame A is connected to the ceiling plate 23, and the other lower end is connected to a frame member (not shown) between the box frame A and the sash.

Next, FIGS. 3a and 3b show another example of a box frame of a joint frame, and this box frame B has a base frame member 1 and a hanging wall member 2 in the same way as box frame A described above. The base frame member 1 is made of a metal shape with a substantially U-shaped cross section, and is equipped with a curtain rail a on the lower surface of the top wall, and a downwardly opening groove inside the lower portions of both sides. A connecting groove 4 having a portion 5 is formed. The hanging wall member 2 is also made of a metal profile, and has a hook-shaped ridge 24 at the upper end.
A connecting edge 6 is provided to protrude upward from the tip of the projecting edge 24. The connecting edge 6 is set to fit loosely into the connecting groove 4, and has a swollen protrusion 7 formed at its tip. Further, an engagement groove 25 that opens upward is formed in the upper part of the hanging wall member 2, and a locking groove 27 is formed on the opposite side of the engagement groove 25.
The holding fitting 3 has exactly the same structure as described above.

When connecting the base frame member 1 and the hanging wall member 2, first, as shown in FIG. The holding fittings 3 are fitted and attached at intervals of , and then the lower end edge 26 of the base frame member 1
At the same time, the end of the connecting edge 6 of the hanging wall member 2 enters inside the base piece 14 of the holding fitting 3. In the connecting groove 4 of the hanging wall member 2, the outer engaging piece 15 of the holding fitting 3 engages with the inner wall of the constricted portion 5 in the connecting groove 4, and cannot escape. In addition, the inner engaging piece 17 on the tip side
is engaged with the base of the distal end bulge 7 when the base frame member 1 comes off, thereby preventing the connecting edge 6 from coming off;
The connecting edge 6 of the hanging wall member 2 is securely held in the connecting groove 4 of the base frame member 1 via the holding fitting 3.

As described above, even if the base frame member 1, the connection groove 4, and the connection edge 6 of the hanging wall member 2 face each other vertically, It is reliably and firmly connected to the wall member 2.

Also in the above box frame, two
The connecting portions 40, 40 formed by the connecting groove 4 and the connecting edge 6 formed in each of the two frame members,
It is formed to protrude so as to face the inside of the hanging wall part. Blind hanger b on the top surface of these connections.
Since both ends b1, b1 of the hanging tool (or lighting equipment, etc.) can be locked, either one can be selected depending on the conditions at the site.

Next, when attaching the box frame B having the above structure to the corner between the ceiling D and the wall E, first attach rod-shaped rods hanging from the top of the ceiling D along the corner at regular intervals. Attach the hanging fixture 31 to the support fixture 30,
The box frame B may be attached via the hanging tool 31. In this case, the hanging tool 31 has an upper engagement piece 3
2 and the lower clamping pieces 33, 33 are connected,
The engagement piece 32 is formed with an engagement groove 32a that fits into the support fitting 30, and the clamping piece 3
3, 33 have upward locking parts 34,
34 are provided. The above-mentioned hanging tool 31 has the above-mentioned rod-shaped support fitting 30 inserted into its engagement groove 32a,
Adjust up and down to engage in the optimal position. At this time,
Since the clamping pieces 33, 33 protrude downward, the box frame B is pushed up from below and its upper part is pushed between the clamping pieces 33, 33. holding piece 33,
When the tip of the locking portion 3 passes through the locking grooves 27, 27 on the outside of the approximately middle portion of the box frame B, the locking portion 3
4 and 34 are locked in these locking grooves 27 and 27. Since the locking grooves 27, 27 are formed in the hanging wall members 2, 2 of the box frame B, the hanging wall members 2, 2 are suspended by the hanging fixture 31.
When the base frame member 1 and the hanging wall member 2 are connected in the vertical direction as described above, the possibility that the hanging wall member 2 will fall off from the connection portion is eliminated.

Note that one lower end of the hanging wall member 2 is connected to the ceiling plate 2.
3, and the other lower end is connected to a frame member 38 between the sash and the frame member 38. A connecting edge 6 is formed protrudingly on the side of one of the hanging wall members 2, whereas a connecting groove 4 is provided at one end of the frame member 38.
By arranging the holding fittings 3 at regular intervals in the connecting groove 4 and elastically fitting the connecting edge 6 into the holding fittings 3 in the connecting groove 4 in the same manner as described above, the hanging wall member 2 and the frame member 38 are connected. The other end of the frame member 38 is fixed to a sash upper frame 39, a wall, or the like. In this case as well, the same linking effect as above can be obtained.

Furthermore, in the case where a connecting edge is provided on one frame member and a connecting groove is provided on the other frame member, and the connecting edge is inserted into the connecting groove via a holding metal fitting and connected to form an integral joint frame, the above-mentioned In addition, for example, the fourth
As shown in Figure a, a sawtooth-like uneven portion 4a is formed on the inner wall of the connecting groove 4 of one frame member, and the connecting edge 6 of the other frame member is inserted into the connecting groove 4 via the holding fitting 3 to connect it. It may also be a configuration. Since the holding fitting 3 can select the locking position of the uneven portion 4a, fine adjustment is possible. In this case, contrary to the above, as shown in FIG. It may be configured to be connected by being inserted into the connecting groove 4 of the other frame member, or alternatively, it may be configured such that both the connecting edge and the connecting groove are provided with the above-mentioned serrated uneven portions.

In addition, it is also possible to make the said clamping piece 33 into a joint frame structure, and it is also possible to make frame members single bodies into a joint frame structure.

(Effects of the invention) As explained in detail above, the joint frame such as a box frame according to the present invention overlaps the ends of two frame members connected to each other, and connects the end of one frame member to the other frame member. While the frame member is locked in the engagement groove formed in the middle part of the frame member, a U-shaped elastic holding fitting is fitted into the connection groove formed in the middle part of one of the frame members to hold the frame member. Inserting the connecting edge formed at the end of the other frame member inside the metal fitting,
An outer engaging piece formed protruding on the outside of the holding fitting is engaged with the inner wall of the connecting groove, and an inner locking piece formed protruding on the inside of the holding fitting is engaged with the swollen protrusion at the tip of the connecting edge. A connecting portion formed by a connecting groove and a connecting edge formed in each of the two frame members is formed protruding from inside the hanging wall portion, and a blind is provided on the upper surface of the connecting portion. It has a configuration in which both ends of the box frame are locked.

Therefore, 2 can be easily installed without using screws etc.
A joint frame can be constructed by connecting two frame members. Furthermore, if some force is applied to only one frame member, for example due to rough handling of the curtain, the two frame members will rotate relative to each other, so the connecting edge will rotate in the direction of coming out of the connecting groove. It may move. However, in this case, the relative rotation of the two frame members is a rotation centered on the locking portion with the engagement groove and with a radius of the overlapping portion of the two frame members, and the rotation radius is large. , the angle of the connecting edge within the connecting groove does not change much. Therefore, since the holding fitting does not move much, the engagement with the connecting edge and the connecting groove is held stably and reliably, and there is no fear that the connecting edge will come off. Therefore, danger such as one frame member falling can be prevented.

Moreover, the connecting portion formed by the connecting groove and the connecting edge formed in the two frame members on each side of the hanging wall portion is formed to protrude so as to face the inside of the hanging wall portion, and the connecting portion Since both ends of a hanger such as a blind or a lighting fixture can be locked to the top surface of the blind box, the connection part of the frame member can also be used as the locking part of the blind box frame. Therefore, there is no need to specially form a locking part for a blind, a lighting fixture, etc. on the hanging wall part, and each frame member can be easily formed.

On the other hand, in the joint frame structure shown in Japanese Utility Model Application Publication No. 55-3915, in addition to the locking parts for hanging tools such as blinds and lighting equipment, the connecting parts of the frame members protrude inside the hanging wall part. Therefore, when a hanging tool is to be locked to the above-mentioned locking portion, force must be applied to the hanging tool to deform it in order to pass over the connecting portion, which makes the work cumbersome.
