Description

[Technical field]

[0001] The present invention relates to a drawer guide unit and a drawer guide unit for a galley container. [Background technology]

[0002] Conventionally, galley units including many storage compartments have been used in interior facilities for vehicles such as aircraft in order to store items while making the most of the limited space in the passenger service area. For example, the following Patent Document 1 is a prior art document that discloses this type of galley unit.

[0003] Galley containers that store, for example, food and beverages are stored in the storage compartment of the galley unit. The galley containers can be stored above the floor level, and are generally taken in and out by cabin crew or loaders (those who take them in and out). In particular, in aircraft and the like, galley containers are often stored above the heads of cabin crew or loaders (those who take them in and out). However, since galley containers that store food and beverages are heavy objects, the task of pulling out or storing the galley containers from the storage compartment is a heavy load. For this reason, conventional galley units are provided with a galley container pull-out guide unit that assists cabin crew or loaders (those who take them in and out) in pulling out the galley containers stored in the storage compartment located at a high position of the galley unit from the storage compartment.

[0004] A conventionally known pull-out guide unit for a galley container has one end of a wire connected to a handle, and the other end of the wire is connected to an engagement member that engages with the galley container.This engagement member is always located at the innermost position of the storage compartment due to the elastic force exerted by an elastic body such as a spring, and is equipped with a mechanism whereby when a flight attendant or loader (person loading or unloading) pulls the handle, the engagement member moves to the entrance side of the storage compartment, thereby pulling out a galley container stored in the storage compartment. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Special Publication No. 2010-514605 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the above-mentioned conventionally known pull-out guide units for galley containers are used for repeatedly pulling out galley containers, which are heavy items, so that the elastic bodies such as handles, wires and springs are prone to breakage, and there is also room for improvement in terms of operability.

[0007] The present invention has been made in consideration of the problems existing in the prior art described above, and its object is to provide a drawer guide unit and a drawer guide unit for galley containers that are less prone to damage and have improved operability compared to the prior art. [Means for solving the problem]

[0008] The drawer guide unit according to the present invention is a drawer guide unit used for drawing out an article stored in a storage section from the storage section, and comprises a linear guide device including at least a fixed member attached to an inner wall surface of the storage section, a track member attached to the fixed member, and a movable member that slides in the longitudinal direction of the track member, an L-shaped plate attached to the movable member and engages with a wall surface on the rear side of the storage section of the article stored in the storage section, an elastic force applying member held by the fixed member and applying an elastic force that urges the movable member in a direction opposite to the drawing-out side of the article, and a handle connected to the movable member or the L-shaped plate via a wire, the wire being a single wire. The handle and the movable member or the L-shaped plate are connected by a two-strand structure, with both ends of the wire attached to the movable member or the L-shaped plate and the middle being looped around a wire holding portion built into the handle, and when the handle is pulled toward the side from which the article is to be pulled out, the wire connecting the handle and the movable member or the L-shaped plate by the two-strand structure exerts a pull-out force against the elastic force of the elastic force imparting member, causing the L-shaped plate to pull out the article from the storage section, and when the pull on the handle is released, the elastic force exerted by the elastic force imparting member urges the L-shaped plate toward the side opposite to the side from which the article is to be pulled out.

[0009] The pull-out guide unit for a galley container according to the present invention is a pull-out guide unit for a galley container used for pulling out a galley container stored in a storage compartment of a galley unit from the storage compartment, and comprises a linear guide device including at least a fixed member attached to an inner wall surface of the storage compartment, a track member attached to the fixed member, and a movable member that slides in the longitudinal direction of the track member, an L-shaped plate attached to the movable member and engages with the container wall surface on the rear side of the galley container stored in the storage compartment, an elastic force applying member held by the fixed member and applying an elastic force that biases the movable member in the opposite pull-out direction of the galley container, and a wire connected to the movable member or the L-shaped plate. and a handle for connecting the movable member or the L-shaped plate to the galley container, wherein both ends of the wire are attached to the movable member or the L-shaped plate and the middle portion is wrapped around a wire holding portion built into the handle, thereby connecting the handle and the movable member or the L-shaped plate in a two-strand structure, and when the handle is pulled toward the pull-out side of the galley container, the wire connecting the handle and the movable member or the L-shaped plate in a two-strand structure exerts a pull-out force against the elastic force of the elastic force imparting member, causing the L-shaped plate to pull the galley container out of the storage compartment, and when the pull on the handle is released, the elastic force exerted by the elastic force imparting member biases the L-shaped plate toward the opposite pull-out side of the galley container. Effect of the Invention

[0010] According to the present invention, it is possible to provide a drawer guide unit and a drawer guide unit for a galley container which are less susceptible to damage and have improved operability compared to the prior art. [Brief description of the drawings]

[Diagram 25] FIG. 25 is a diagram showing a specific structural example of the configuration shown typically in FIG. 24. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Preferred embodiments for carrying out the present invention will be described below with reference to the drawings. Note that the following embodiments do not limit the inventions according to the claims, and all of the combinations of features described in the embodiments are not necessarily essential to the solution of the invention.

[0013] First, referring to Figures 1 and 2, an example of a galley unit 10 in which a galley container drawer guide unit 20 according to this embodiment is installed and used is shown. Here, Figure 1 is a diagram showing an example of a galley unit to which a galley container drawer guide unit according to this embodiment is applied. Also, Figure 2 is a diagram showing an example of a state in which a galley container drawer guide unit according to this embodiment is installed in a storage compartment of a galley unit.

[0014] The galley unit 10 in which the galley container drawer guide unit 20 according to this embodiment is installed and used is used for interior equipment for vehicles such as aircraft. The galley unit 10 has a plurality of storage compartments 11, and the galley containers 12 can be stored in or drawn out from the plurality of storage compartments 11. In the galley unit 10 of this embodiment, the galley containers 12 are stored in the storage compartments 11 by cabin crew or loaders (those who take them in and out) manually. In the case of the storage compartment 11 shown in Figs. 1 and 2, a plurality of galley containers 12 (for example, two) can be stored in series in the depth direction. In this case, the galley containers 12 stored in the front side can be manually drawn out by cabin crew or loaders (those who take them in and out), but the galley containers 12 stored in the back side cannot be manually drawn out by cabin crew or loaders (those who take them in and out). In this way, the galley container drawer guide unit 20 of this embodiment is used when pulling out a galley container 12 that is stored at the back of the storage compartment 11 and out of reach of people.

[0015] The drawer guide unit 20 for a galley container according to this embodiment can be installed and used on the inner side wall surface of the storage compartment 11, as shown in Fig. 2. Therefore, in the following explanation, a case will be described in which the drawer guide unit 20 for a galley container according to this embodiment is installed on the right side wall surface of the storage compartment 11 of the galley unit 10. In other words, in the explanation of this embodiment, the directions of "front / back, left / right, and up / down" will be defined based on the directions in the usage state when installed on the right side wall surface of the storage compartment 11. However, these directions do not limit the usage state of the drawer guide unit for a galley container according to the present invention.

Fig. 19 is a perspective view of an L-shaped plate and a part of a wire constituting the pullout guide unit for a galley container according to this embodiment, as viewed from the front lower left. Fig. 20 is a perspective view of an L-shaped plate and a part of a wire constituting the pullout guide unit for a galley container according to this embodiment, as viewed from the rear upper right. Fig. 21 is a right side view for explaining a state in which the handle, wire guide, and wire constituting the pullout guide unit for a galley container according to this embodiment are in use, with (a) showing the initial state and (b) showing the state when the handle is pulled forward.

[0017] As shown in Figures 3 to 7, the pull-out guide unit 20 for a galley container in this embodiment is mainly composed of a fixed member 21, a linear guide device 31, an L-shaped plate 41, an elastic force imparting member 51, and a handle 61.

[0018] The fixed member 21 is a plate-shaped member attached to the right inner wall surface of the storage compartment 11. The linear guide device 31, the elastic force applying member 51, and the wire guide 71 (described later) are fixed to the left side surface of the fixed member 21, and the right side surface is attached to the right inner wall surface of the storage compartment 11.

[0019] As shown in more detail in Figures 10 and 11, the linear guide device 31 includes a track rail 32 as a track member attached to the fixed member 21, and a movable member 33 that slides in the longitudinal direction of the track rail 32 (i.e., the front-to-rear direction).

[0020] The track rail 32 is a long rail member having a substantially C-shaped or U-shaped longitudinal section, and has a pair of track rail side sliding grooves 32a formed as groove shapes extending in the longitudinal direction with respect to the vertical positions of the inner peripheral surface of the substantially C-shaped or U-shaped. On the other hand, the moving member 33 has a pair of moving member side sliding grooves 33a formed in the longitudinal direction with respect to the vertical positions of the outer peripheral surface. The pair of track rail side sliding grooves 32a and the pair of moving member side sliding grooves 33a are arranged opposite to each other. Furthermore, between the track rail side sliding grooves 32a and the moving member side sliding grooves 33a arranged opposite to each other, a sliding member 34 made of oil-impregnated resin and having a cylindrical shape is interposed. Therefore, in the linear guide device 31, the moving member 33 slides in the longitudinal direction of the track rail 32 fixed to the fixed member 21, but since the sliding member 34 made of oil-impregnated resin exists between the moving member 33 and the track rail 32, the moving member 33 can realize a stable sliding motion.

[0021] An L-shaped plate 41 is attached to the moving member 33 of the linear guide device 31 described above. In this embodiment, the moving member 33 and the L-shaped plate 41 are fixed by bolts in a state in which a spacer member 35 shown in Fig. 8 and Fig. 9 is sandwiched between the moving member 33 and the L-shaped plate 41. The spacer member 35 is used to connect and fix the moving member 33 and an elastic force imparting member 51 described later.

[0022] The L-shaped plate 41 of this embodiment is bolted to the movable member 33, so that it can slide in the longitudinal direction of the track rail 32 fixed to the fixed member 21. An L-shaped portion 42 that is bent to the left side in the sliding movement direction is formed on the rear side of the L-shaped plate 41, and the L-shaped portion 42 can engage with the container wall surface on the rear side of the galley container 12, and the L-shaped plate 41, which maintains this engaged state, moves forward, so that the galley container 12 can be pulled out from within the storage compartment 11.

[0023] On the other hand, a wire 45 is fixed to the front side of the L-shaped plate 41, as shown in Figures 6, 7, 15 and 16. Also, the L-shaped plate 41 of this embodiment has an additional shaped portion 43 curved downward and rearward, as shown in Figures 19 and 20, and the formation of the additional shaped portion 43 improves the rigidity of the L-shaped plate 41.

[0024] The elastic force imparting member 51 is a member that is held by the fixed member 21 and exerts an elastic force that urges the moving member 33 of the linear guide device 31 toward the opposite side to the pull-out side of the galley container 12. As shown in Figs. 12 to 14, the elastic force imparting member 51 according to this embodiment includes a winding drum 52 rotatably held by the fixed member 21, a spring force transmitting wire 53 wound around the winding drum with one end 53a fixed to the winding drum 52 and the other end 53b fixed to the moving member 33, a spiral spring 55 that urges the winding drum 52 in the winding direction of the spring force transmitting wire 53, and a spiral spring protective cover 54 that is installed on the right side of the winding drum 52 to protect the spiral spring 55. Therefore, the elastic force imparting member 51 is configured such that the spiral spring 55 always exerts an elastic force that urges the moving member 33 toward the opposite side to the pull-out side (i.e., the rear side) of the galley container 12.

[0025] With regard to the attachment of the spring force transmission wire 53 to the winding drum 52 and the movable member 33, one end 53a and the other end 53b of the spring force transmission wire 53 are spherical in shape, and the spherical shape of one end 53a of the spring force transmission wire 53 is fixed by engaging with the locking groove 52a of the winding drum 52 (see Figures 13 and 14), and the spherical shape of the other end 53b of the spring force transmission wire 53 is fixed by fitting it into the locking groove 33b of the movable member 33, covering it with a spacer member 35 and bolting it in place (see Figure 8).

[0026] The handle 61 is a member that is connected to the movable member 33 via the wire 45. More specifically, the handle 61 incorporates a pulley 62 therein as a wire holder, as shown in Fig. 17. The pulley 62 is protected from the outside by a pulley protection cover 61a that is attached to the handle 61, as shown in Fig. 15.

[0027] On the other hand, the wire 45 is attached to the front side of the L-shaped plate 41, the both ends of which are fixed to the movable member 33, and the middle portion of the wire 45 is wound around a pulley 62 built into the handle 61. In other words, the L-shaped plate 41 and the handle 61 in this embodiment are configured to connect the wire 45 in a two-wire structure.

[0028] Therefore, in the galley container pull-out guide unit 20 of this embodiment, when the handle 61 is pulled toward the pull-out side (i.e., toward the front) of the galley container 12, the wire 45 connecting the handle 61 and the L-shaped plate 41 with a two-piece structure exerts a pull-out force that resists the elastic force of the elastic force-applying member 51, and as a result, the L-shaped plate 41 engaged with the galley container 12 moves toward the front, allowing the L-shaped plate 41 to pull out the galley container 12 from the storage compartment 11.

[0029] Furthermore, in this embodiment, when the handle 61 is operated to slide the L-shaped plate 41 (movable member 33) via the wire 45 connected in a two-strand structure to pay out or reel in the spring force transmitting wire 53 from the winding drum 52, the spiral spring 55 always exerts an elastic force that urges the L-shaped plate 41 (movable member 33) toward the side opposite the pull-out side (i.e., the rear side) of the galley container 12. Therefore, when the handle 61 is released from tension, the L-shaped plate 41 is urged toward the side opposite the pull-out side (i.e., the rear side) of the galley container 12 by the elastic force exerted by the elastic force imparting member 51, and can easily return to its initial position.

[0030] 3 to 5, the handle 61 is disposed via a wire guide 71 installed on the pull-out side (i.e., the front side) of the galley container 12 in the fixing member 21. As shown in more detail in Fig. 18, the wire guide 71 of this embodiment has a guide wall 72 that guides the pull-out and storage of the wire 45 that connects the handle 61 and the L-shaped plate 41 in a two-wire structure, and this guide wall 72 is configured as a curved wall surface having a curvature.

[0031] As shown in the partial view (a) of Fig. 21, the guide wall 72 formed in the wire guide 71 is preferably configured such that the inequality 2R / d≧20 holds when the diameter of the wire 45 is d and the radius of curvature of the curved wall surface constituting the guide wall 72 is R. This conditional expression contributes to realizing smooth extension and retraction of the wire 45 by guiding the extension and retraction of the two-stranded wire 45 when the handle 61 is pulled out obliquely downward, for example, as shown in the partial view (b) of Fig. 21. The pulley 62 built into the handle 61 realizes, by its pulley structure, a state in which the elastic force from the spiral spring 55 is applied equally to both of the wires 45 connected by the two-stranded structure. Furthermore, although the wire guide 71 does not directly have the effect of preventing damage to the handle 61, for example, if the shape of the wire guide has a sharp R shape that does not satisfy the above conditional formula, the wire 45 may become bent, the handle 61 may be stored in an upright position, and the handle 61 may come into contact with articles such as the galley container 12 and be damaged. For this reason, the wire guide 71 of this embodiment, by having a shape that satisfies the above conditional formula, can indirectly exert the effect of preventing damage to the handle 61.

[0032] Furthermore, in this embodiment, the guide wall 72 formed on the wire guide 71 has a curved shape that satisfies the conditions of the above inequalities, and a configuration is adopted in which the handle 61 and the L-shaped plate 41 are connected by a two-strand wire 45. Therefore, no matter in what direction the handle 61 is pulled out, the wire 45 is unlikely to twist and has high resilience, making it possible to achieve smooth pulling out and storage of the wire 45.

[0033] moreover , Books The pull-out guide unit 20 for galley containers in the embodiment adopts a configuration in which the handle 61 and the L-shaped plate 41 are connected by a two-strand wire 45, thereby achieving the effect of having high strength and making the wire 45 less likely to break.

[0034] The above describes the configuration of the galley container drawer guide unit 20 according to this embodiment. Next, a method of using the galley container drawer guide unit 20 according to this embodiment will be described.

[0035] When pulling out the galley container 12, which is stored in the back of the storage compartment 11 and out of reach of people, a cabin attendant or a loader (a person who takes it in or out) applies a pulling force against the elastic force of the spiral spring 55 by pulling the handle 61 forward. This pulling force is transmitted to the L-shaped plate 41 through the wire 45 that connects the handle 61 with a two-wire structure. Since the L-shaped plate 41 is fixed to the moving member 33 of the linear guide device 31, it slides forward along the track rail 32 of the linear guide device 31. At this time, the L-shaped portion 42 formed on the L-shaped plate 41 engages with the container wall surface on the back side of the storage of the galley container 12, so that the L-shaped plate 41, which maintains this engaged state, moves forward, and the galley container 12 can be pulled out from within the storage compartment 11. When a cabin attendant or a loader (a person loading or unloading) pulls the handle 61 forward, the handle 61 and the L-shaped plate 41 are connected by the two-stranded wire 45, which is stronger and less likely to break than the conventional technology. The two-stranded wire 45 is guided in its pulling-out operation by the guide wall 72 formed as a curved wall surface having a curvature relative to the wire guide 71, and the pulley 62 built into the handle 61 smoothly adjusts the length of the two-stranded wire 45, thereby achieving a smooth pulling-out operation.

[0036] As described above, after the galley container 12 is pulled out from the storage compartment 11, when the cabin attendant or the loader (the person loading or unloading) releases the pulling force applied to the handle 61, the pulling force on the L-shaped plate 41 that was being received from the handle 61 is released, and the L-shaped plate 41 slides rearward due to the elastic force of the spiral spring 55 and automatically returns to its initial position. At this time, too, the wire guide 71 appropriately guides the storage operation of the two-strand wire 45, and the pulley 62 built into the handle 61 smoothly adjusts the length of the two-strand wire 45, realizing a stable return operation.

[0037] Although the preferred embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the above embodiments. Various modifications and improvements can be made to the above embodiments.

[0038] For example, in the above embodiment, the drawer guide unit according to the present invention has been described as a galley container drawer guide unit 20 used for drawing out the galley container 12 stored in the storage compartment 11 of the galley unit 10 from the storage compartment 11, but the drawer guide unit according to the present invention is not limited to being used for drawing out the galley container 12. The drawer guide unit according to the present invention can be used for drawing out all kinds of articles stored in various types of storage units.

[0039] For example, in the above embodiment, the galley container drawer guide unit 20 is installed on the right side wall of the storage compartment 11 of the galley unit 10. However, the galley container drawer guide unit 20 according to this embodiment can also be installed on the left side wall of the storage compartment 11 of the galley unit 10. In this case, the above-mentioned galley container drawer guide unit 20 can be used by inverting it upside down. In this way, the galley container drawer guide unit 20 according to this embodiment can be commonly applied to both the left and right walls of the storage compartment 11, and has a structure with a wide range of applications. The galley container drawer guide unit 20 according to this embodiment can be used not only on the left and right walls of the storage compartment 11, but also in any direction and in any posture.

[0040] For example, in the above-described embodiment, a case has been illustrated in which both ends of a single wire 45 having a two-strand structure are fixed to the L-shaped plate 41, but both ends of a single wire 45 having a two-strand structure may also be fixed to a movable member 33 that slides and moves together with the L-shaped plate 41.

[0041] Also, for example, in the above-described embodiment, the handle 61 has a pulley 62 built therein as a wire holding portion, and the wire 45 is wound around this pulley 62, thereby connecting the handle 61 and the moving member 33 via the wire 45. However, the wire holding portion of the present invention is not limited to the pulley 62. For example, a wire holding portion of a type that holds the wire 45 by sliding contact with it may also be used.

[0042] Also, for example, in the above embodiment, an example was given of the case where the galley container pull-out guide unit 20 according to this embodiment is used when pulling out the galley container 12 that is stored at the back of the storage compartment 11 and in a position that is out of reach of people, but the galley container pull-out guide unit of the present invention can also be used when pulling out a galley container 12 that is in a position that is within reach of people. In other words, the galley container pull-out guide unit of the present invention can be used when pulling out a galley container in any position, attitude, or condition.

[0043] For example, in the above-described embodiment, the linear guide device 31 was of a type that performed a sliding motion, but the linear guide device applied to the galley container pull-out guide unit of the present invention may also be of a type that performs a rolling motion by interposing a plurality of rolling bodies (balls, rollers, rollers, etc.) between the track member and the movable member.

[0044] Also, for example, in the above-mentioned embodiment, as shown in FIG. 20, cylindrical stop sleeves 46 are provided at both ends of one wire 45 having a two-strand structure, and the stop sleeves 46 are hooked into slit grooves 47 formed in the L-shaped plate 41, thereby fixing both ends of the wire 45 to the L-shaped plate 41. However, in the fixing method using the stop sleeves 46, there is a small possibility that the wire 45 rotates and the two-strand wire 45 is twisted. Therefore, it is preferable that the attachment sites between both ends of the wire 45 and the L-shaped plate 41 are attached by connection parts 81 having a ring terminal shape that makes the wire 45 non-rotatable, as shown in FIG. 22. Here, FIG. 22 is a diagram showing an example of a connection part 81 that can be adopted as an attachment site between both ends of the wire 45 and the L-shaped plate 41. A specific attachment method will be described with reference to FIG. 22. The L-shaped plate 41 is provided with tap holes 48, and both ends of the one wire 45 having a two-strand structure are provided with connection parts 81 having a ring terminal shape. From this state, the wire 45 is passed through the slit groove 47 formed in the L-shaped plate 41, and the screw shaft of the bolt 83 is passed through the through hole of the connection part 81 having a ring terminal shape, and the bolt 83 is screwed into the tapped hole 48 to complete the fixing of both ends of the wire 45 to the L-shaped plate 41. At this time, since the connection part 81 fixed to the L-shaped plate 41 has a ring terminal shape, the wire 45 is fixed to the L-shaped plate 41 in a non-rotatable state. Therefore, according to the structural example shown in FIG. 22, the wire 45 does not rotate, and it is possible to preferably prevent the occurrence of a problem such as the twisting of the two-stranded wire 45. Note that, as for the connection part according to the present invention that makes the wire 45 non-rotatable, in addition to the ring terminal shape shown in FIG. 22, a Y-shaped terminal shape, a hook-shaped terminal shape, or the like may be adopted.In addition, in the structural example shown in FIG. 22, tapped hole 48 and bolt 83 are used as a means for fixing L-shaped plate 41 and connection portion 81, but as a means for fixing the L-shaped plate and connection portion of the present invention, any fixing means known in the art can be used, such as, for example, providing an untapped through hole in the L-shaped plate and using a bolt and nut fixing means in which the threaded shaft of a bolt is passed through this through hole and fastened with a nut, using a rivet fixing means, or using a welding fixing means.

[0045] For example, further improvements can be made to the galley container drawer guide unit 20 according to the embodiment described above, and examples of such improvements will be described with reference to Figures 23 to 25. Here, Figure 23 is a schematic diagram showing the state in which the handle 61 and the wire guide 71 of the galley container drawer guide unit 20 according to this embodiment are in contact with each other, as viewed in a direction parallel to the inner wall surface of the storage compartment 11 to which the fixing member 21 is attached and perpendicular to the direction in which the handle 61 is pulled (i.e., the up-down direction), with the partial view (a) in the figure showing the normal state and the partial view (b) showing the state in which a malfunction has occurred. 24 is a schematic diagram showing the operating state when the handle 61 of the galley container pull-out guide unit according to the improved embodiment of the present invention comes into contact with the wire guide 171, as viewed in a direction parallel to the inner wall surface of the storage compartment 11 to which the fixing member 21 is attached and perpendicular to the direction in which the handle 61 is pulled (i.e., vertical direction), and the state in which the handle 61 comes into contact with the wire guide 171 as a result of being pulled by the wire 45 is shown in sub-views (a) and (b) in the figure. Furthermore, FIG. 25 is a diagram showing a specific structural example of the configuration shown in FIG. 24. In FIG. 23 to FIG. 25, the same reference numerals are used for the same or similar members as those in the above-mentioned embodiment, and the description thereof is omitted.

[0046] As shown in FIG. 23, the handle 61 and the wire guide 71 of the above-mentioned embodiment are formed with a flat surface at the contact points. Therefore, when the handle 61 is pulled by the wire 45 and contacts the wire guide 71, the handle 61 is normally aligned with the inner wall surface of the storage compartment 11 (see the sub-diagram (a) in FIG. 23). However, when the handle 61 is repeatedly pulled out and retracted, the handle 61 may come into contact with the wire guide 71 in a state where it is raised up against the inner wall surface of the storage compartment 11 (see the sub-diagram (b) in FIG. 23). If such a state occurs, the handle 61 or the wire 45 may be damaged. Therefore, when the handle 61 comes into contact with the wire guide 71, it is necessary to always maintain a state where the handle 61 is aligned with the inner wall surface of the storage compartment 11 without rising up. Therefore, the present inventors have succeeded in eliminating the above-mentioned defective state by devising the configuration of an improved example shown in FIG. 24. Such an improved example will be described with reference to FIG. 24.

[0047] In the case of the improved example shown in Fig. 24, the shape of the part of the wire guide 171 that comes into contact with the handle 61 is formed as a convex shape 172a at a part distant from the fixed member 21 and as a concave shape 172b at a part close to the fixed member 21, so that the wire guide 171 has a stepped shape 172 consisting of a convex shape 172a and a concave shape 172b. Therefore, when the handle 61 is pulled by the wire 45, the handle 61 is pulled by the wire 45 with the part of the wire guide 171 that comes into contact with the convex shape 172a as a fulcrum and a part closer to the fixed member 21 than the fulcrum as a force point, so that a force is always applied to the handle 61 so that the handle 61 is always pressed against the inner wall surface of the storage compartment 11. Therefore, in the case of the improved example shown in Fig. 24, the handle 61 does not rise up against the inner wall surface of the storage compartment 11, and always maintains a state along the inner wall surface of the storage compartment 11. That is, according to the improved example shown in Fig. 24, the raised state of the handle 61, which may cause damage to the handle 61 or the wire 45, can be suitably prevented, thereby realizing a pull-out guide unit 20 for a galley container that maintains normal operation and has few malfunctions. Note that, in order to achieve this effect, it is necessary to provide a configuration in which the point where the handle 61 contacts the wire guide 171 is taken as a fulcrum, the point where the handle 61 receives the elastic force applied by the elastic force applying member 51 via the wire 45 is taken as a force point, and the point where the handle 61 is pressed against the inner wall surface of the storage compartment 11 is taken as a point of action, in which the point of action, point of force, and fulcrum are arranged in this order in a direction away from a position close to the inner wall surface of the storage compartment 11 (see the sub-diagram (b) in Fig. 24).

[0048] Next, a structural example that specifically realizes the improved example shown in FIG. 24 is shown in FIG. 25. As shown in FIG. 25, the shape of the part of the wire guide 171 that contacts the handle 61 is formed as a convex shape 172a at a part distant from the fixed member 21 and as a concave shape 172b at a part close to the fixed member 21. When the handle 61 is pulled by the wire 45, the handle 61 is pulled by the wire 45 with the part of the wire guide 171 that contacts the convex shape 172a as a fulcrum and a part closer to the fixed member 21 than the fulcrum as a force point, so that the handle 61 is always pressed against the inner wall surface of the storage compartment 11. That is, a force is applied to the handle 61 in a state of contact with the wire guide 171 so that the handle 61 is always pressed against the inner wall surface of the storage compartment 11. Therefore, in the structural example shown in FIG. 25, the handle 61 does not rise up against the inner wall surface of the storage compartment 11, and can always maintain a state along the inner wall surface of the storage compartment 11.

[0049] In the improved examples and structural examples shown in Figures 24 and 25, an example is shown in which step shape 172 is formed on the wire guide 171 side, but the step shape according to the present invention may be provided on the handle 61 side, or on both the wire guide 171 and the handle 61.

[0050] It will be apparent from the description of the claims that such modified or improved forms may also be included within the technical scope of the present invention. [Explanation of symbols]
