Description

Technical Field

[0001] The invention relates to a bottle fixing device. Background Art

[0002] In order to respond to emergencies in the cabin in a timely manner, emergency equipment (portable fire extinguishers, portable oxygen cylinders) are arranged horizontally in the aircraft luggage compartment. The cabin luggage compartment has a small space. For example, if a PBE (Protective Breathing Equipment: breathing protector) is arranged above a portable fire extinguisher, the space will be more tight, resulting in a small operating space for the portable fire extinguisher.

[0003] Civil aircraft portable fire extinguisher bottles and portable oxygen bottles usually use clamps to fix the bottle body to the support frame, and the support frame is fixed to the cabin interior panel or luggage compartment interior through fasteners. Fig.13 As shown, a fire extinguisher bottle fixing device is known, in which a metal fixing clamp 2A with a buckle is installed on a support frame 1A to fix the bottle body of the fire extinguisher bottle PA, and the fixing clamp 2A limits the movement of the bottle body in the X and Z directions; a limiting end is formed at the front end of the support frame 1A, and the limiting end is provided with a groove 3A for clamping the neck of the fire extinguisher bottle PA, thereby limiting the movement of the fire extinguisher bottle PA in the Y direction.

[0004] When using the above-mentioned fire extinguisher bottle fixing device, the bottle body relies on the clamping rigidity of the buckle structure, and the bottle body is easily scratched because the clamp is inelastic. In the process of taking out the fire extinguisher bottle, the bottle body is easy to rub against the sharp corner of the limit end, scratching the bottle body. For example, when taking out the fire extinguisher bottle PA, first, loosen the buckle on the fixed clamp 2A; then, lift the bottle body upward, avoid the limit end at the front end, and take it out obliquely upward. Due to the combined influence of the height of the suitcase and the small equipment space, the bottle body may be scratched, worn, and even damaged by metal structures such as the fixed clamp 2A, the buckle, and the limit end at the front end during the process of taking out the bottle, resulting in the scrapping of the fire extinguisher bottle.

Fig. 9 1 is a perspective view showing the limiting frame 3 of the bottle fixing device 100 .

[0056] The bottle fixing device 100 disclosed in the present invention can be used as a bracket for portable fire extinguisher bottles, portable oxygen bottles, etc., for example, for fixing and installing bottle equipment such as aircraft fire extinguisher bottles, oxygen bottles, etc. In this embodiment, the fire extinguisher bottle P (see FIG. Fig.10 ) is used as an example to explain the bottle fixing device 100.

[0057] The bottle fixing device 100 of the present disclosure comprises a support frame 1 , a flexible cassette 2 , a limit frame 3 and a linkage mechanism. The linkage mechanism comprises a gear G1 , a first rack G2 , a second rack G3 , and a movable member 4 .

[0058] like Figure 1 to Figure 3 As shown, the support frame 1 comprises a first portion 11 and a second portion 12 fixed to the first portion 11 .

[0059] The first portion 11 is, for example, rectangular in plan view with its long side along the Y direction (equivalent to the "second direction" of the present invention) and its short side along the X direction (equivalent to the "first direction" of the present invention). A placement portion 11a having an arc-shaped cross section is formed on the Z1 side surface of the first portion 11 for placing the fire extinguisher bottle P.

[0060] An anti-friction pad may be provided on the back side of the loading portion 11a and the flexible cassette 2 (the side facing the fire extinguisher bottle P), thereby preventing or preventing the fire extinguisher bottle P from being damaged during clamping and preventing the fire extinguisher bottle P from being scratched during the installation / removal path. For example, an anti-friction pad may be provided at the contact point between the flexible cassette 2 and the fire extinguisher bottle P.

[0061] The first portion 11 is provided with a first support portion 112 for supporting a first elastic urging member T1 described below. More specifically, the first portion 11 is provided with a first opening 111 penetrating along the Z direction (third direction). The first portion 11 is provided with a portion closer to the Y2 side than the first opening 111 to form the first support portion 112.

[0062] In addition, the support frame 1 can be installed on an installation object (such as a cabin interior panel, a luggage compartment interior, etc.) by fasteners such as screws. For example, corner pieces 113 are provided at the four corners of the first portion 11, and the corner pieces 113 are fixed to the installation object by screws.

[0063] The second portion 12 is, for example, a rectangle having a smaller dimension in the Y direction than the first portion 11 when viewed from above. The second portion 12 has a relative portion 121 and a first folded edge 122 and a second folded edge 123 bent in the Z1 direction from both ends of the relative portion 121 in the X direction. The relative portion 121 is opposite to the first portion 11 from the Z2 side. The first folded edge 122 and the second folded edge 123 are connected to both sides of the first portion 11 from the outside in the X direction.

[0064] The flexible cassette 2 is used to limit the radial movement of the fire extinguisher bottle P (movement in a direction orthogonal to the Y direction). The flexible cassette 2 is arranged in the middle of the bottle fixing device 100 in the Y direction. When viewed from above (along the Z direction), the flexible cassette 2 is in the shape of a long strip extending in the X direction. The two ends of the flexible cassette 2 are respectively fixed to the first rack G2 and the second rack G3. When the first rack G2 and the second rack G3 move toward or away from each other in the X direction, the flexible cassette 2 is contracted or relaxed. After the fire extinguisher bottle P is installed in place, the flexible cassette 2 is in a contracted state. For example, in a relaxed state, when viewed along the Y direction, the flexible cassette 2 is in an inverted U shape.

[0065] (Linkage Agency)

[0066] The linkage mechanism includes a gear G1 , a first rack G2 , a second rack G3 , and a movable member 4 .

[0067] The gear G is rotatably supported on the support frame 1 via the shaft GL. The shaft GL extends in the Z direction. For example, the shaft GL is provided in the space between the first portion 11 and the second portion 12 (the opposing portion 121 thereof), and is supported on at least one of the Z2 side surface of the first portion 11 and the Z1 side surface of the second portion 12. The shaft GL rotatably supports the gear G on at least one of the first portion 11 and the second portion 12.

[0068] When viewed in the Z direction, the gear G is located in the middle of the support frame 1 in the X direction. The Y direction position of the gear G overlaps with the flexible cassette 2, for example. The gear G can rotate around an axis (axis of the shaft GL) extending in the Z direction. The gear G has a plurality of teeth arranged on the outer peripheral surface centered on the axis of the shaft GL.

[0069] The first rack G2 and the second rack G3 are driven racks. The first rack G2 and the second rack G3 are supported on the support frame 1 so as to be movable along the X direction. Figure 7 As shown, the first rack G2 has a first tooth portion G21 including a plurality of first teeth G211 arranged in the X direction and with the tooth tops facing the Y1 side. The second rack G3 includes a second tooth portion G31 including a plurality of second teeth G311 arranged in the X direction and with the tooth tops facing the Y2 side. The first tooth portion G21 and the second tooth portion G31 are opposite to each other in the Y direction. The lengths (in the X direction) of the first tooth portion G21 and the second tooth portion G31 can be appropriately set according to the movement strokes of the first rack G2 and the second rack G3.

[0070] The first rack G2 and the second rack G3 are meshed with the gear G1 from both sides in the Y direction (see Figure 5). The gear G1 is located between the first rack G2 and the second rack G3, and meshes with the first tooth portion G21 of the first rack G2 and the second tooth portion G31 of the second rack G3, respectively. The first tooth portion G21 of the first rack G2 on the X1 side meshes with the gear G1 from the Y2 side. The second tooth portion G31 of the second rack G3 on the X2 side meshes with the gear G1 from the Y1 side.

[0071] In addition, in the first rack G2, a first straight line portion G22 extending in the X direction may be provided at intervals on the Y1 side of the first tooth portion G21 (see Figure 7 ), and contacts the surface of the second tooth portion G31 on the side opposite to the side where the second tooth G311 is provided (Y1 side). The surface on the Y1 side of the second tooth portion G31 extends linearly in the X direction. The first straight portion G22 is located on the Y1 side of the second tooth portion G31. In the second rack G3, a second straight portion G32 extending in the X direction may be provided at intervals on the Y2 side of the second tooth portion G31, and contacts the surface of the first tooth portion G21 on the side opposite to the side where the first tooth G211 is provided (Y2 side). The surface on the Y2 side of the first tooth portion G21 extends linearly in the X direction. The second straight portion G32 is located on the Y2 side of the first tooth portion G21. Through the straight portions G22 and G32, when the first rack G2 and the second rack G3 move in the X direction, the first tooth portion G21 and the second tooth portion G31 can be reliably meshed with the gear G1.

[0072] The support frame 1 may include a first guide portion for guiding the movement of the first rack G2 and the second rack G3 along the X direction. More specifically, the first folded edge 122 and the second folded edge 123 of the second portion 12 are respectively provided with notches 124 and 125 penetrating along the X direction (see Figure 2 , Figure 3 ). The first rack G2 and the second rack G3 are respectively arranged through the notches 124 and 125. For example, when the flexible cassette 2 is in a relaxed state, a portion of the first rack G2 is located in the space between the first portion 11 and the opposite portion 121 of the second portion 12, and another portion is exposed from the notch 124; a portion of the second rack G3 is located in the space between the first portion 11 and the opposite portion 121 of the second portion 12, and another portion is exposed from the notch 125. The shapes of the notches 124 and 125 match the first rack G2 and the second rack G3.

[0073] For example, when the first rack G2 and the second rack G3 move in the X direction, the first rack G2 slides on the Z1 side surface of the opposite portion 121 while meshing with the gear G1; the second rack G3 slides on the Z1 side surface of the opposite portion 121 while meshing with the gear G1. The notches 124 and 125 are first guides for guiding the movement of the first rack G2 and the second rack G3 in the X direction. The notches 124 and 125 restrict the first rack G2 and the second rack G3 to move only in the X direction. In addition, a convex strip protruding from one of the opposite portion 121 and the first portion 11 to the other may be provided as the first guide instead of or in addition to the notches 124 and 125.

[0074] The first rack G2 is connected to the flexible cassette 2 at the X1 side end. The second rack G3 is connected to the flexible cassette 2 at the X2 side end.

[0075] In addition, recesses 114 ( Figure 3 , only one recess 114 is shown). The position of the recess 114 in the Y direction corresponds to the notches 124 and 125, and receives the end of the flexible cassette 2 when the flexible cassette 2 is contracted by the first rack G2 and the second rack G3. The recess 114 may have a bottom surface with an arc-shaped cross section, which cooperates with the flexible cassette 2 in the contracted state. Through the recess 114, the movement of the flexible cassette 2 can be guided, and the flexible cassette 2 can be contracted and relaxed more smoothly.

[0076] The movable member 4 is supported on the support frame 1 so as to be movable in the Y direction. The movable member 4 has a movable main body 41 and a holding portion 42. The movable main body 41 is in the shape of a plate extending along the XY plane. For example, the part of the movable main body 41 on the Y1 side is located in the space between the first part 11 and the opposing part 121 of the second part 12.

[0077] The supporting portion 42 is used to support the bottom of the fire extinguisher bottle P. The supporting portion 42 is folded from the Y2 side end of the movable main body portion 41 to the Z1 side. The supporting portion 42 is in the shape of a plate extending along the XZ plane. The movable main body portion 41 is located closer to the Z2 side than the first portion 11. The movable member 4 moves in the Y direction in a manner that the supporting portion 42 passes through the first opening portion 111. The first opening portion 111 (or the first opening portion 111 and the second guide portion described below) limits the movable member 4 to move only in the Y direction.

[0078] The movable member 4 is provided with a movable rack portion G4 as an active rack. The movable rack portion G4 meshes with the gear G1. More specifically, the movable member 4 (the movable main body portion 41) is provided with a long hole 43 (see FIG. Figure 5). The long hole 43 passes through the movable main body 41 along the Z direction. When viewed along the Z direction, the inner peripheral wall of the long hole 43 is composed of two sides extending along the Y direction and an arc-shaped side connecting the two sides. The gear G1 is located in the long hole 43. A movable rack part G4 having a plurality of third teeth G41 arranged along the Y direction and with the tooth tops facing the X direction is provided at one side of the inner peripheral wall of the long hole 43 extending along the Y direction. That is, the movable rack part G4 is provided on the inner peripheral wall of the long hole 43. In the present embodiment, the movable rack part G4 is provided on the side on the X1 side of the two sides extending along the Y direction of the inner peripheral wall of the long hole 43. The length (in the Y direction) of the movable rack part G4 can be appropriately set according to the moving stroke of the movable part 4. In addition, instead of the side on the X1 side, a movable rack part can be provided on the side on the X2 side of the two sides extending along the Y direction of the inner peripheral wall of the long hole 43. In this case, the first rack gear on the X1 side has a first tooth portion that meshes with the gear from the Y1 side, and the second rack gear on the X2 side has a second tooth portion that meshes with the gear from the Y2 side.

[0079] The support frame 1 may include a second guide portion for guiding the movement of the movable member 4 in the Y direction. For example, the movable body portion 41 of the movable member 4 can slide on the Z1 side surface of the opposing portion 121 while meshing with the gear G1. A groove or a track may be provided on the Z1 side surface of the opposing portion 121 to form the second guide portion for guiding the movement of the movable member 4 in the Y direction.

[0080] When the movable member 4 moves in the Y direction, the movable rack G4 drives the gear G1 to rotate, thereby driving the first rack G2 and the second rack G2 to move toward or away from each other, so as to shrink or loosen the flexible cassette 2.

[0081] The bottle fixing device 100 may include a first elastic urging member T1. At least after the fire extinguisher bottle P is installed in place, the first elastic urging member T1 urges the movable element 4 toward the Y1 side (the direction for taking out the fire extinguisher bottle P).

[0082] The support frame 1 has a first support portion 112 located on the Y2 side relative to the supporting portion 42. The first elastic force member T1 is, for example, a coil spring located between the supporting portion 42 and the first support portion 112. When the movable part 4 is subjected to a thrust force transmitted, for example, via the fire extinguisher bottle P and moves toward the Y2 side, the coil spring T1 is compressed and reacts to the bottom of the fire extinguisher bottle P. The coil spring serving as the first elastic force member T1 is connected to the supporting portion 42 at the end on the Y1 side, and / or is connected to the first support portion 112 at the end on the Y2 side. In addition, the first elastic force member T1 may also adopt other elastic force members known in the art.

[0083] In this case, for example, a pull-out portion (not shown) connected to the movable element 4 is provided, and the movable element 4 can be manually pulled or pushed in the Y direction to move the movable element 4 .

[0084] (Limiting frame)

[0085] The limit frame 3 is used to limit the movement of the fire extinguisher bottle P along the Y direction. The limit frame 3 is detachably mounted on the Y1 side end of the support frame 1. After removing the limit frame 3, the fire extinguisher bottle P can be taken out along the extension direction of the bottle body (Y direction). In this way, the fire extinguisher bottle P can be prevented from being scratched by the sharp corner of the limit end of the device during the process of taking out or putting in.

[0086] like Fig. 9 As shown, the limit frame 3 has a handle 31 and two arms 32, 32. The handle 31 is in the shape of a plate extending along the XZ plane. The handle 31 is opposite to the holding portion 42 in the Y direction. The handle 31 has a groove 311 that contacts the neck of the fire extinguisher bottle P. The groove 311 is formed concavely from the Z1 side end surface of the handle 31 to the Z2 side. When viewed along the Y direction, the groove 311 is U-shaped. At least the curved bottom of the groove 311 can be provided with an anti-friction pad to avoid or suppress scratch damage to the fire extinguisher bottle P.

[0087] The arms 32, 32 are fixedly connected to the handle 31. For example, the arms 32, 32 protrude from the handle 31 toward the Y2 side. In this embodiment, the two arms 32 have a symmetrical structure (but not limited to this, and can also be an asymmetrical structure). The two arms 32 are respectively located on both sides of the handle 31 in the X direction. The arms 32 are columnar (for example, cylindrical). A retractable spring pin 33 is installed on the arm 32. Fig. 9 By pressing the spring pins 33 at the left / right positions of the limiting frame 3 , the limiting frame 3 can be disengaged from the supporting frame 1 .

[0088] For example, the spring pin 33 includes a spring 331, a limit card 332 and a button 333 disposed at one end of the spring 331. The support arm 32 is provided with a spring pin receiving portion open in a direction perpendicular to the Y direction (in this embodiment, the X direction) for receiving the spring 331 of the spring pin 33. The two ends of the spring 331 are respectively fixed to the support arm 32 (the bottom wall of the spring pin receiving portion) and the limit card 332. The limit card 332 is integrated with the button 333 and exposed outward from the support arm 32. The operation button 333 realizes the locking and unlocking functions of the spring pin 33.

[0089] The support frame 1 is provided with two receiving portions 13 (see FIG. Figure 3). The storage portion 13 has an inner wall surface that is recessed from the Y1 side end surface of the first portion 11 to the Y2 side. A snap-in hole 131 is provided through the side wall of the storage portion 13. When the support arm 32 is stored in the storage portion 13, the spring pin 33 (button 333) is snap-fitted into the snap-in hole 131. When the button 333 is not subjected to a pressing force, it is located at the origin position under the action of the spring 331. The spring 331 can be compressed by pressing the button 333 and pressed into the snap-in hole 131, so that the button 333 is retracted from the snap-in hole 131. At this time, the limit frame 3 can be removed from the support frame 1 by pulling the handle 31 toward the Y1 side. On the other hand, when the limit frame 3 is installed on the support frame 1, the support arm 32 is pushed (inserted) into the storage portion 13 along the Y direction while pressing the button 333. When the support arm 32 moves to the specified position, the position of the button 333 is aligned with the snap-in hole 131. The button 333 pops out under the action of the spring 331 and snaps into the snap-in hole 131, and the limit frame 3 is installed.

[0090] The limit frame 3 may have a second elastic force member T2 to assist the limit frame 3 in smoothly withdrawing (removing from the support frame 1). At least when the support arm 32 is stored in the storage portion 13, the second elastic force member T2 applies force to the support arm 32 in the removal direction. For example, the second elastic force member T2 is a coil spring located between the front end (Y2 side end) of the support arm 32 and the bottom wall of the storage portion 13. The second elastic force member T2 may be connected to the support arm 32 at the Y1 side end, or connected to the storage portion 13 at the Y2 side end. In addition, it is also possible that the second elastic force member T2 is arranged between the support arm 32 and the storage portion 13 in a manner not connected to either the support arm 32 or the storage portion 13. In addition, the second elastic force member T2 may also be omitted.

[0091] In addition, the limiting frame 3 can be removed from the support frame 1 by the force of the first elastic force member T1 (via the fire extinguisher bottle P), or the limiting frame 3 can be removed from the support frame 1 by the force of the first elastic force member T1 and the second elastic force member T2.

[0092] (How to use the bottle fixing device 100)

[0093] Fig.10 1 is a diagram schematically showing the action when the limiting frame 3 is removed. The left part of the diagram shows a state where the limiting frame 3 is installed on the support frame 1 , and the right part shows a state where the limiting frame 3 is about to be removed from the support frame 1 . Fig.11 2 is a diagram schematically showing the action when taking out the fire extinguisher bottle P. The upper part of the diagram shows the state when the fire extinguisher bottle P is taken out, and the lower part shows the state when the fire extinguisher bottle P is further taken out. Fig.12 3 is a diagram schematically showing the installation of the limit frame 3 , wherein the left portion of the diagram shows a state where the limit frame 3 is not installed in place, and the right portion shows a state where the limit frame 3 is installed on the support frame 1 .

[0094] The bottle fixing device 100 disclosed in the present invention can automatically loosen / tighten the bottle body when the fire extinguisher bottle P is taken out / pushed in, which can solve the problem that the operation is cumbersome and the tightness of the clamp cannot be adjusted when the bottle body is fixed by a clamp in the previous bottle body bracket. In addition, the applicability of installing bottles of different sizes can be achieved by designing and replacing the length of the first elastic force-applying member and the flexible cassette (adapting to the fixing requirements of bottles of various sizes).

[0095] The bottle fixing device 100 disclosed in the present invention can automatically tighten the flexible cassette 2 as the fire extinguisher bottle P slides when loading (fixing). Loading the fire extinguisher bottle P includes: first, removing the limit frame 3. Next, insert the fire extinguisher bottle P from the Y1 side, make the bottom of the fire extinguisher bottle P abut against (closely adhere to) the supporting portion 42, and push the supporting portion 42 toward the Y2 side (via the fire extinguisher bottle P) to move the movable part 4 toward the Y2 side (in the case where a coil spring is provided as the first elastic force applying member T1, the coil spring is compressed). At this time, the gear G1 is driven to rotate by the movable rack portion G4 of the movable part 4 ( Figure 5 , counterclockwise rotation); the rotating gear G1 drives the first rack G2 and the second rack G3 that are meshed together to move toward each other (moving toward each other), and both ends of the flexible cassette 2 move inward at the same time, and the flexible cassette 2 is gradually tightened. When the movable part 4 moves to the specified installation position, the flexible cassette 2 tightens the fire extinguisher bottle P (in the case where a coil spring is provided as the first elastic force component T1, the tightening force of the flexible cassette 2 is determined by the pre-tightening force of the first elastic force component T1). In this way, the flexible cassette 2 can shrink in conjunction with the fire extinguisher bottle P. Then, the limit frame 3 is installed on the support frame 1. Thus, the fire extinguisher bottle P is installed.

[0096] When the flexible cassette 2 is in a contracted state, the fire extinguisher bottle P is limited from both sides in the Y direction by the supporting portion 42 and the limiting frame 3 .

[0097] When taking out the fire extinguisher bottle P, first, remove the limit frame 3. Then, move the movable member 4 to the Y1 side. At this time, the movable rack G4 of the movable member 4 drives the gear G1 to rotate ( Figure 5 The rotating gear G1 drives the first rack G2 and the second rack G3 that are meshed together to move in the direction of separation from each other (movement in opposite directions), and the flexible cassette 2 gradually becomes loose, and the fire extinguisher bottle P can be taken out.

[0098] For example, in the case of a coil spring as the first elastic urging member T1, the movable member 4 can be moved to the Y1 side by the force of the first elastic urging member T1 when the fire extinguisher bottle P is taken out. In this case, when the fire extinguisher bottle P is taken out, the coil spring as the first elastic urging member T1 is restored from the compressed state, assisting the operator to take out the fire extinguisher bottle P along the Y direction, and the slack of the flexible cassette 2 increases.
