(Covering Member) As shown in FIGS. 2, 3, and 4 (a) and (b), the covering member 40 is a component that extends in the left-right direction to constitute the front end portion of the cover member 2. As shown in FIGS. 4A and 4B, the cover member 40 includes a cover upper wall portion 41, a cover front wall portion 42, and cover side walls 43 a and 43 b. The cover upper wall portion 41 is formed flat and constitutes a part of the top surface 2 a of the cover member 2 (see FIG. 1). A pair of projecting portions 41 a having a substantially triangular shape in plan view protruding rearward is formed on the rear portion of the cover upper wall portion 41. As shown in FIG. 2, each protruding portion 41 a covers corner portions 55 and 55 on the rear side of the operation panel 5 to be described later from above.

The cover front wall portion 42 extends downward from the front side of the cover upper wall portion 41 to constitute the front side surface of the cover member 2 (see FIGS. 5 (a) and (b)). A holding recessed portion 42 a is formed at a center portion in the left-right direction of the cover front wall portion 42. The holding recessed portion 42a is recessed inward (rearward) than the left end surface 42b or the right end surface 42c of the cover front wall portion 42 (see FIGS. 5 (a) and (b)). As shown in FIG. 4 (b), the holding recessed portion 42a has a slightly inverted ladder shape in front view. The holding recess 42a is formed by surrounding the bottom wall 42a1, the left wall 42a3, and the right wall 42a4, and the top surface and the bottom surface are open (see FIG. 4 (a)). The upper end opening of the holding recessed portion 42 a opens upwards of the cover member 2 and functions as an insertion opening for a finger when the cover member 2 is opened and closed.

On the other hand, as shown in FIG. 3, the lower end of the holding recessed portion 42a is opposed to the central recessed portion 15a of the recessed portion 15 of the box body 1 with the lid member 2 closed to the box body 1. 15a is closed. According to this, the finger that fits or inserts the holding recessed portion 42a is restricted from moving the finger below the central recessed portion 15a by the central recessed portion 15a, preventing the finger from falling off from the holding recessed portion 42a. Therefore, a finger can be firmly arranged in the holding recess 42a.

The bottom wall 42a1 is formed with a concave surface 42a5 recessed rearward (see FIGS. 5 (a) and (b)). The concave surface 42a5 has a slightly inverted ladder shape in front view. The concave portion 42a5 is a lower portion 42a6 of the bottom wall 42a1 that protrudes below the left end face 42b or the right end face 42c of the cover front wall portion 42 (see Figs. 5 (b) and (c)). As shown in Figs. 3, 4 (b), and (c), the lower portion 42a6 is made to project the shape of the central recessed portion 15a of the recessed portion 15 of the box body 1, and is configured to be disposed at least partially within the central recessed portion 15a (see the figure) 3). That is, the bottom wall 42a1 of the holding recessed portion 42a is formed by the side surface (front) of one end side of the cover member 2 across the side surface (front) of one end side of the box body 1 corresponding to the side surface. According to this, the holding recessed portion 42 a is provided with a height dimension larger than the height dimension of the front side surface of the cover member 2 in the thickness direction, and an area for holding is secured. In addition, the grip recessed portion 42 a has a size (a recessed space in which a finger can be placed) that can fit or hold a finger of an adult male. The depth of the bottom wall 42a1 of the holding recessed portion 42a can be appropriately set as long as it can fit or hold a finger.

As shown in FIG. 4 (b), the left wall 42a3 and the right wall 42a4 face each other in the left-right direction and form a tapered shape that gradually becomes wider in the left-right direction from the lower end to the upper end. Accordingly, the opening area of the upper end opening of the holding recess 42a is wider than the lower end opening on the side opposite to the upper end opening (see FIG. 4 (a)).

Since the cover side walls 43a and 43b have a left-right symmetrical structure, the left cover side wall 43a will be described here. As shown in FIG. 5 (c), the cover side wall 43 a covers the left side portion of the cover member 40. The cover side wall 43a is formed with a fixing hole 43c for fixing an end portion of the shaft member 45 of a lock plate (see FIG. 8 (a)) described later. The right side cover wall 43 b covers the right side of the cover member 40.

Next, the structure of the back surface of the cover member 40 will be described mainly with reference to FIG. 8. In addition, in FIG. 8, in order to make the structure easier to see, a portion protruding behind the cover member 40 is painted with a dot.

Behind the cover front wall portion 42 are formed as ribs protruding rearward from the cover front wall portion 42: horizontal ribs 46 extending from the left and right cover side walls 43a, 43b to the left and right inner sides; and horizontal ribs 46 The inner end in the left-right direction extends upward and continues to the upper and lower ribs 47 of the cover upper wall portion 41. In addition, there are formed an inner rib 48 extending from the upper and lower ribs 47 to the inner side in the left-right direction, and a central rib 42e extending to the left-right direction in the rear center portion of the cover front wall portion 42. In addition, a plurality of rod support portions 44 that are engaged with the rod portion 16a (see the two-point chain line) of the engaged portion 16 to support the rod portion 16a are provided behind the cover front wall portion 42 and extend in the left-right direction. A shaft member 45; a lock plate 6 rotatably arranged on the shaft member 45; and a pushing member 7. The lock plate 6 and the urging member 7 are configured by the lock mechanism 4 and will be described later.

The horizontal ribs 46 and the upper and lower ribs 47 are used to increase the strength of the covering member 40. The horizontal rib 46, the upper and lower ribs 47, and the cover upper wall portion 41 constitute a rectangular rectangular frame portion 47c. A protrusion 35 of the cover body 30 is fitted into the rectangular frame portion 47c, and the cover body 30 and the cover member 40 are integrated together (see FIG. 6). In addition, although not shown in particular, a screw that penetrates the horizontal rib 46 from below is screwed to the protrusion 35 so that the protrusion 35 does not fall out of the rectangular frame portion 47c.

The inner rib 48 is continued to the middle portion in the vertical direction of the upper and lower ribs 47. Therefore, as shown in FIG. 8 (b), the inner rib 48, the upper and lower ribs 47, and the cover upper wall portion 41 constitute a slightly C-shaped wall portion. Hereinafter, the C-shaped wall portion is referred to as a guide portion 49. The description of the guide portion 49 will be described later.

As shown in FIG. 6, a notch 44 a is formed at the lower end of the rod support portion 44. The rod portion 16 a of the engaged portion 16 enters the notch 44 a from below, and the rod portion 16 a is engaged with the rod support portion 44.

As shown in FIG. 8 (a), the shaft member 45 penetrates the rod support portion 44 disposed in the left-right direction, and both ends are fixed to the respective fixing holes 43c of the left and right cover side walls 43a, 43b (see FIG. 5 (c)).

(Operation Panel Storage Section) As shown in FIG. 1, the operation panel storage section 20 is used to arrange the operation panel 5 below the top surface 2 a of the cover member 2. According to this, even if another cold storage box 100 is placed on the top surface 2 a of the cover member 2, it is stable. As shown in FIG. 7, the operation panel storage portion 20 is formed by recessing the top surface of the front end portion 34 of the cover body 30 downward, and includes a bottom surface 25 and a rear surface 26, a left surface 27, and a right surface 28.

As shown in FIG. 2, the width L1 between the left side surface 27 and the right side surface 28 gradually decreases from the front toward the rear. The width L1 is formed such that the middle of the front and rear directions is a boundary line, and the front side has a larger width than the operation panel 5 and the rear side has a smaller width than the operation panel 5. In other words, the width L1 includes a wider area formed by the width of the operation panel 5 and a narrow area formed by the width of the operation panel 5. Therefore, the operation panel 5 can be arranged on the front side of the operation panel storage portion 20. On the other hand, the operation panel 5 disposed on the front side of the operation panel storage portion 20 cannot be moved rearward so that the rear end portion of the operation panel 5 does not abut the rear side surface 26 of the operation panel storage portion 20. As a result, a gap S2 in which a finger can be inserted is always formed between the rear side surface 26 and the operation panel 5.

As shown in FIG. 7, the bottom surface 25 is located below the cover upper wall portion 41 of the cover member 40, and an opening portion S1 is formed between the bottom surface 25 of the operation panel storage portion 20 and the cover upper wall portion 41 of the cover member 40. The cover member 2 is filled with a heat insulating material 33 in a portion located below the operation panel storage portion 20.

(Grip portion) The grip portion 21 includes a front grip surface 22 facing forward, a grip surface 23 facing backward (rear) in a direction opposite to the front grip surface 22 in the operation panel storage portion 20, and upward and upward. Grasping surface 24. The grip portion 21 projects more upward than the bottom surface 25 of the operation panel housing portion 20 and is convex in cross section. Therefore, it can be grasped by pinching the fingers in the front-rear direction.

The front holding surface 22 is formed by the bottom wall 42a1 of the aforementioned holding recessed portion 42a. The rear grip surface 23 is constituted by a rear end surface (operation surface 53 a) of the operation panel 5 stored in the operation panel storage portion 20. The rear grip surface 23 faces the direction (rear) opposite to the bottom wall 42a1 of the grip recessed portion 42a inside the operation panel storage portion 20. The details of the operation panel 5 will be described later. The upper grip surface 24 is a surface for contacting the palm from above (see each figure in FIG. 9). The upper grip surface 24 is configured by a cover upper wall portion 41 of the cover member 40. In addition, the contact area between the hand and the holding portion 21 is increased by the upper holding surface 24, and the holding can be performed firmly.

Next, the lock mechanism 4 and the operation panel 5 constituting the opening and closing device 3 will be described. As shown in FIG. 8 (a), the lock mechanism 4 includes the aforementioned engaged portion 16 (see FIGS. 1 and 4 (c)), a lock plate 6, and a pressing member 7.

(Lock plate) The lock plate 6 is a resin-made plate-like member extending in the left-right direction. The locking plate 6 is penetrated by the shaft member 45 in the central portion in the vertical direction, and is rotatable around the shaft member 45. The locking plate 6 includes a pressed portion 60 located at the center in the left-right direction and extending upward from the shaft member 45, and claw portions 70 located at both sides in the left-right direction and extending downward from the shaft member 45. In addition, one end of the urging member 7 is locked to the horizontal rib 46, and the other end is locked to the back of the claw portion 70, and the claw portion 70 is always pushed toward the back of the cover front wall portion 42 (toward the front of the cool box 100) (see Arrow in Fig. 6). Therefore, the pressed portion 60 integrated with the claw portion 70 is pushed to move (rotate) to the rear of the cool box 100 (refer to the arrow in FIG. 7).

The pressed portion 60 is a plate-like member formed in a long direction in the left-right direction and is located between the left and right upper and lower ribs 47. As shown in FIG. 7, the upper end 60 a of the pressed portion 60 extends to the vicinity of the cover upper wall portion 41 of the cover member 40, and is located above the bottom surface 25 of the operation panel storage portion 20. In addition, the upper end 60a is formed in a semicircular shape in cross section.

As shown in FIG. 6, the claw portion 70 includes a plate portion 72 extending downward from the shaft member 45 and a protrusion 73 protruding from the lower end of the plate portion 72 forward. Since the plate portion 72 is pushed forward by the urging member 7 (see FIG. 8 (a)), the front portion abuts the rod portion 16 a of the engaged portion 16. By this abutment, the lock plate 6 is prevented from rotating.

The protrusion 73 abuts the bottom surface of the rod portion 16a. Therefore, even if a force is applied to move the front end side of the cover member 2 upward, the protrusion 73 is locked to the rod portion 16 a and restricted (locked) so that the front end side of the cover member 2 does not move upward. Accordingly, the closed state of the cover member 2 is maintained. In addition, since the periphery of the rod portion 16a is surrounded by the rod support portion 44 and the claw portion 70, the cover member 2 is rotatably connected around the rod portion 16a.

(Operation Section) As shown in FIG. 10, the operation panel 5 has a substantially rectangular shape in plan view, and is a component formed long in the left-right direction. Further, the operation panel 5 is formed with a pressing surface 52a at the front end surface and an operation surface 53a at the rear end surface.

As shown in FIG. 7, the operation panel 5 is stored on the front side of the operation panel storage section 20 and is placed on the bottom surface 25 of the operation panel storage section 20. The corner portions 55 and 55 on the rear side of the operation panel 5 abut on the left side 27 and the right side 28 of the operation panel storage portion 20 (refer to the operation panel 5 disposed on the rear side in FIG. 2), and the rearward movement is restricted. The operation surface 53 a (rear end surface) of the operation panel 5 faces rearward in the operation panel storage portion 20, and constitutes a rear grip surface 23 of the grip portion 21.

The front end portion of the operation panel 5 is inserted into an opening portion S1 formed between the operation panel storage portion 20 and the cover member 40. The front end portion of the operation plate 5 is disposed between the left and right upper and lower ribs 47 (see FIG. 8 (a)), and the pressing surface 52 a of the operation plate 5 abuts the pressed portion 60 of the lock plate 6. Therefore, a load facing the front and greater than the urging force of the urging member 7 acts on the operation panel 5, and while pressing the pressed portion 60, the operation panel 5 slides (horizontally moves) forward. The detailed configuration of the operation panel 5 will be described later.

Next, a method of opening the cover member 2 will be described with reference to FIG. 9. The method of opening the cover member 2 is composed of a procedure for holding the gripping part 21 and a procedure for lifting the gripping part 21 upward.

As shown in FIG. 9 (a), the procedure for holding the gripping portion 21 first places a hand above the gripping portion 21 with the palm facing downward. Next, the thumb is brought into contact with the front grip surface 22 (the bottom wall 42a1 of the grip recess 42a of the cover member 40), and the palm is brought into contact with the upper grip surface 24 (the cover upper wall portion 41 of the cover member 40). Furthermore, a finger other than the thumb is inserted into the gap S2 between the rear side surface 26 of the operation panel housing section 20 and the operation surface 53a of the operation panel 5 to contact the rear grip surface 23 (operation surface 53a).

In addition, the width L1 in the left-right direction in the gap S2 between the rear side surface 26 and the operation surface 53a is narrower than that of the operation panel 5 (see FIG. 2), and it is difficult for a finger to contact the left and right ends of the operation surface 53a. Therefore, it is guided so that a finger touches the center part of the operation surface 53a.

Next, each finger is bent such that the thumb approaches four fingers other than the thumb, and the grip portion 21 is held. Accordingly, as shown in FIG. 9 (b), the operation surface 53a is pressed, the operation panel 5 is moved forward, and the pressed portion 60 is rotated. Then, the engagement between the left and right claw portions 70 and the rod portion 16 a (see FIG. 6) of the engaged portion 16 is released, and the front side of the cover member 2 can be moved (rotated) upward. When the pressed portion 60 comes into contact with the rear face of the cover front wall portion 42, the lock plate 6 stops rotating. Therefore, the operation panel 5 is restricted from moving forward, and the holding portion 21 can be held (held) in the front-rear direction.

Here, for example, if the pressing surface 52a is inclined and pressed only by the left end of the pressing portion 60 (hereinafter referred to as [single-end contact]), the left claw 70 is fully rotated, but the right claw 70 There is little fear that the engagement with the engaged portion 16 will not be released. In this case, according to the embodiment, since the finger is guided so as to contact the central portion of the operation surface 53a, in other words, to press the central portion of the operation surface 53a, the possibility of single-end contact is small. Therefore, the engagement between the left and right claw portions 70 and the engaged portion 16 is reliably released.

Next, while maintaining the state in which the grip portion 21 is held, the hand is moved upward. Accordingly, as shown in FIG. 9 (c), the front end side of the cover member 2 is lifted upward. After that, if the hand is moved to the upper side, the rod portion 16 a of the engaged portion 16 in the opening and closing device 3 on the rear side of the cover member 2 is rotated as a center, and the upper opening 10 of the box body 1 is opened.

The above is the opening operation method of the cover member 2. Further, if the aforementioned operations are performed on the front grip portion 21 and the rear grip portion 21 at the same time, the locks of the lock mechanisms 4 provided on the front and back sides are released, and the cover member 2 can be removed from the box body 1.

Next, the operation panel 5 will be described in detail. As shown in FIG. 10, the operation panel 5 includes a body portion 50 having a substantially rectangular shape in plan view; a rib 51 for operation portions extending near the center of the bottom surface of the body portion 50 forward and backward; and extending downward along the front end of the body portion 50. The front wall 52 forms the pressing surface 52a; the front wall 52 extends along the rear end of the main body portion 50; the rear wall 53 forms the operation surface 53a; the upper end surface of the rear wall 53 extends to the obliquely extending extension 54; A corner of the rear side of the portion 50 extends to the lower corner portion 55; and a side wall 56 of the main body portion 50 extends along the left and right end edges.

As shown in FIG. 10 (a), an upper sliding portion 50 a protruding upward is formed on the front edge side of the top surface of the main body portion 50. As shown in FIG. 10 (b), a lower sliding portion 51 a is formed on the bottom surface of the operation portion rib 51, which is narrower than the operation portion rib 51. As shown in FIG. 7, the upper sliding portion 50 a is slidably abutted against the bottom surface of the cover upper wall portion 41. The lower sliding portion 51 a is slidably abutted against the bottom surface 25 of the operation panel storage portion 20. The upper sliding portion 50a and the lower sliding portion 51a suppress the vertical movement of the operation panel 5. In addition, the contact area can be reduced compared to the case where the top surface of the main body portion 50 and the bottom surface of the operation portion rib 51 are in contact with each other, and the operation panel 5 can be slid smoothly.

As shown in FIG. 10 (c), the front wall 52 extends linearly in the left-right direction, and the pressing surface 52a becomes a flat surface. The rear wall 53 is curved and the central portion is recessed forward. Further, the extension portion 54 is also curved so as to correspond to the rear wall 53, and the central portion is recessed forward. Therefore, as shown in FIG. 2, the gap S2 between the rear side surface 26 of the operation panel housing portion 20 and the operation panel 5 is the largest compared to the left and right central portions, and can be guided by inserting a finger near the central portion. As a result, the probability that the finger touches the central portion of the operation surface 53 a increases, and it is possible to prevent the single-end contact with the pressed portion 60 due to the operation panel 5.

As shown in FIG. 7, the extending portion 54 extends obliquely from the upper end edge of the operation surface 53 a toward the upper rear side. As shown in FIG. 9 (c), when the extension portion is opened by opening the cover member 2 while holding the grip portion 21, the extension portion 54 catches the finger even if the operation surface 53 a slides off by the finger. Therefore, operability at the time of opening operation of the cover member 2 can be improved. On the other hand, when the cover member 2 is in the closed state, even if the user accidentally hangs a finger on the extension portion 54 and lifts up the finger, the extension portion 54 is inclined, so that the finger easily falls off. Therefore, it is possible to prevent an excessive load from being applied to the operation panel 5 and break it.

As shown in FIG. 10 (b), the left and right side walls 56 are formed so that the length in the vertical direction is shorter than the front wall 52 and the rear wall 53. An upper sliding portion 50 a is formed on the top surface of the side wall 56, and a lower sliding portion 51 a is formed on the bottom surface of the side wall 56. As shown in FIG. 8 (b), the left and right side walls 56 are inserted into the guide portion 49 formed in the cover member 40.

The upper sliding portion 50 a of the side wall 56 is slidably abutted against the bottom surface of the upper wall (the cover upper wall portion 41) of the guide portion 49. The lower sliding portion 51a of the side wall 56 slidably abuts the top surface of the lower wall (inner rib 48) of the guide portion 49. A lateral sliding portion 49 a protruding from the upper and lower ribs 47 into the guide portion 49 is slidably abutted on the outer surface 56 a of the side wall 56. Further, the lateral sliding portion 49 a extends in the front-rear direction and always abuts against the outer surface 56 a of the side wall 56. According to the above configuration, the contact area between the side wall 56 of the operation panel 5 and the guide portion 49 can be reduced, and the operation panel 5 can be slid smoothly. Furthermore, the pressing surface 52a of the operation panel 5 can be held in parallel with the pressed portion 60 by the lateral sliding portion 49a, and the single-end contact of the operation panel 5 can be prevented. As a result, the engagement between the claw portions 70 on the left and right sides and the engaged portion 16 is reliably released.

As described above, according to the embodiment, since one finger can be placed on the bottom wall 42a1 of the holding recessed portion 42a and the one end portion (front portion or rear portion) of the cover member 2 can be held by the fingers, it is easy to perform gripping during opening and closing operations. The cover member 2 has excellent opening and closing operability. In addition, other coolers or other luggage are arranged without any gap on the front side of the cooler box 100 during transportation, even when there is no gap between fingers inserted between the front side of the cooler box 100 and other coolers, etc. A space is also formed between the bottom wall 42a1 of the holding recessed portion 42a and the side surfaces of other cool boxes. Therefore, since the finger can be inserted into the space from above and the front side portion of the cover member 2 is held by the fingers, the opening and closing operability of the cover member 2 is excellent.

Further, since the upper recess opening is formed wider than the lower opening in the thickness direction of the cover member 2 in the thickness direction of the grip member 2, it is easy to put a finger on the recess 42 a for holding, and it is easy to insert a finger into the recess 42 a for holding. Therefore, the cover member 2 is easily held, and the opening and closing operability of the cover member 2 is excellent. Furthermore, the tapered left side wall 42a3 or right side wall 42a4 of the holding recessed portion 42a can be used to insert a hand into the holding recessed portion 42a diagonally from the left or from the right into the holding recessed portion 42a.

Moreover, since the concave surface 42a5 is formed in the holding recessed portion 42a, it is easy to put a finger on the holding recessed portion 42a (bottom wall 42a1), and it is easy to insert a finger into the holding recessed portion 42a. Therefore, the cover member 2 is easily held, and the opening and closing operability of the cover member 2 is excellent.

In addition, since the grip recessed portion 42a is formed by the cover member 2 throughout the box body 1, it is easier to put a finger on the grip recessed portion 42a, and it is easier to insert a finger into the grip recessed portion 42a. Therefore, the cover member 2 is easily held, and the opening and closing operability of the cover member 2 is excellent.

Further, the operation panel 5 is provided with an operation panel 5 that is released from the lock of the lock mechanism 4 by being pressed against one side (for example, the front side) of the cover member 2, and a bottom wall 42 a 1 (for allowing a finger to contact the holding recess 42 a) The bottom surface, the front grip surface 22) and the grip surface 21 of both sides of the operation surface 53a (rear grip surface 23) of the operation panel 5. According to this, it is possible to open the bottom wall 42a1 of the holding recessed portion 42a while grasping the operation plate 5 while pressing it. Therefore, the cover member 2 is easily held, and the opening and closing operability of the cover member 2 is excellent. Then, by holding the grip portion 21, the lock of the lock mechanism 4 is released. That is, if the user wants to contact his finger with the operation surface 53a of the operation panel 5, and then bend the finger to hold the gripping portion 21, the operation surface 53a is pressed by the finger, and the lock of the lock mechanism 4 is released. Therefore, convenience is high and the opening and closing operability of the cover member 2 is excellent.

In addition, since a finger is brought into contact with the side surface of the cover member 2 (the bottom wall 42a1 of the holding recess 42a) to hold the side surface of the cover member 2, the load acting on the operation panel 5 when the cover member 2 is lifted is reduced, and the operation panel Deformation and breakage of 5 are suppressed.

Further, since the upper grip surface 24 (the cover upper wall portion 41) is formed, the grip can be firmly held, and the opening operation of the cover member 2 is stable. In addition, since the front holding surface 22 and the upper holding surface 24 use the cover member 40, there is no risk that the manufacturing of the cover member 2 will be complicated.

In addition, according to the embodiment, the operation panel 5 moves along the bottom surface of the operation panel storage portion 20. In other words, it is not possible to lift a finger by hanging it on the bottom surface of the operation portion as in the conventional technique. Therefore, it is not necessary to form a space for inserting a finger under the operation panel 5, and the operation panel storage portion 20 can be designed shallowly. On the other hand, the thickness of the cover member 2 located below the operation panel storage portion 20 can be greatly designed. (Refer to L2 in FIG. 7). As a result, as in the present embodiment, a heat-insulating material 33 is provided inside the cover member 2 constituting the bottom wall of the operation panel housing portion 20, or a cavity is not formed between the outer wall 31 and the inner wall 32, but the For example, it is possible to fill the outer wall 31 and the inner wall 32 with, for example, a resin material to form a solid, and it is possible to suppress a decrease in heat insulation.

The portion of the cover member 2 located below the operation panel storage portion 20 is the portion having the thinnest thickness in the cover member 2. Therefore, as in the present embodiment, if the heat insulating material 33 is provided inside the cover member 2 constituting the bottom wall of the operation panel storage portion 20, the heat insulation property of the cover member 2 can be effectively improved.

Furthermore, a heat insulating material 33 is provided inside the cover member 2 constituting the bottom wall of the operation panel storage portion 20 so that the heat insulating material 33 covers the entire upper opening 10. Therefore, it is difficult for the cold air in the storage space 11 to escape to the outside through the cover member 2, and the heat insulation property of the cover member 2 is greatly improved.
