1. Field of the Invention
The present invention relates to a storage apparatus, such as cup holders for automotive applications.
2. Description of the Related Art
An automobile is provided with various on-board storage containers, such as console boxes, cup holders and glove compartments. Many storage apparatuses used so far comprise a container body having a top opening, and a lid member for opening and closing the top opening, respectively. Except the instance for putting small articles in or taking them out from a storage apparatus, the lid member covers the opening of the container body to enhance the decorativeness within a vehicle passenger room.
Many lid members are held swingably to a container body. Many lid members used so far are urged by a spring in the opening direction. In this instance, a push-lock opening device is used simultaneously in general. That is, an operator pushes the lid member with a finger to unlock the push-lock opening device so that the lid member is opened automatically by the urging force of the spring. In order to close the opening of the container body, an operator pushes the lid member again to swing so that the push-lock opening device is locked when the lid member closes the opening.
However, since such a storage apparatus is constructed so that the lid member is supported pivotably to the container body, there might arise a problem that the pivotably-supporting shaft is damaged when an excessive load acts onto the closed lid member. Hence, in order to avoid the problem, it has been carried out to provide the lid member with a metallic arm, which extends downward from the lid member and is equipped with a pin for supporting the metallic arm pivotably to the container body. Such a metallic pivotably-supporting construction can inhibit the pivotably-supporting shaft from breaking. However, since the metallic arm is usually formed as s plate shape, the metallic arm might be deformed plastically to result in troubling the opening/closing operation of the lid member when the metallic arm is subjected to an excessive load.
Note that Japanese Unexamined Patent Publication (KOKAI) No. 2003-54,302 discloses a cup holder in which a tray member is made swingable further downward from the horizontal position in order to inhibit the pivotably-supporting shaft from breaking. Moreover, Japanese Unexamined Patent Publication (KOKAI) No. 2000-8,687 discloses a console box whose shaft or bearing hole is formed as a tapered shape to disengage the engagement between the shaft and the bearing hole in order to prevent the breakage.
The present invention has been developed in view of the aforementioned circumstances. It is therefore an object of the present invention to provide a storage apparatus which can inhibit its component parts from breaking and deforming plastically so that the occurrence of opening/closing malfunction is prevented.
A storage apparatus according to the present invention can solve the aforementioned problem, and comprises:
a container body having a top opening;
a lid member for opening and closing the top opening of the container body, the lid member held swingably to the container body;
an arm extending downward from the lid member;
a shaft for pivotably supporting the arm to the container body;
an urging member for urging the lid member upward; and
a slot into which the shaft is fitted so as to pivotably hold the arm, the slot extending up-and-downward; and
the container body further having a receiver, which is brought into contact with the lid member so as to support the lid member when the pivotably-supporting shaft moves relatively within the slot so as to move the lid member downward.
The receiver can preferably have a cross section formed as an arc shape, which is free from interfering with the swinging cover.
The present storage apparatus can preferably further comprise a pin protruding from the arm, wherein: the container body can preferably be provided with a guide groove for guiding a movement of the pin accompanied by the swinging movement of the lid member; and the guide groove can preferably be provided with a descent groove for enabling the pin to move when the shaft moves relatively within the slot so as to move the lid member downward. If such is the case, the urging member can preferably urge the lid member upward by way of the pin.
In accordance with the present storage apparatus, the pivotably-supporting shaft, which supports the arm pivotably, moves relatively within the slot when an excessive load acts onto the lid member, which closes the top opening of the container body, from above. Accordingly, the entire lid member moves downward along with the arm. Consequently, the lid member is brought into contact with the receiver so that the receiver supports the lid member. As a result, no excessive load acts onto the arm and the pivotably-supporting shaft. Therefore, even when the arm is made of a metallic sheet, the arm is inhibited from deforming plastically. Thus, the present storage apparatus can prevent the opening/closing malfunction from occurring. Moreover, since no excessive load acts onto the arm and the pivotably-supporting shaft, it is possible to make the arm and/or the pivotably-supporting shaft of resin instead of metal. Hence, it is possible to furthermore reduce the weight of the present storage container.
Moreover, when the present storage container further comprises the pin, which protrudes from the arm; and the container body is provided with the guide groove, which guides a movement of the pin accompanied by the swinging movement of the lid member, the present storage container can produce a good operation feeling because the pin moves in the guide groove so as to enable the lid member to open and close the top opening of the container body stably during the ordinary opening/closing operation. In addition, when the lid member is subjected to an excessive load, the pin moves in the descent groove, which is formed in the guide groove, so as to enable the lid member to descend. Therefore, the deformation of the arm is inhibited so that the present storage apparatus can prevent the occurrence of the opening/closing malfunction in the same manner as described above.
A more complete appreciation of the present invention and many of its advantages will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings and detailed specification, all of which forms a part of the disclosure.
Having generally described the present invention, a further understanding can be obtained by reference to the specific preferred embodiments which are provided herein for the purpose of illustration only and not intended to limit the scope of the appended claims.
A storage apparatus according to the present invention comprises a container body, and a lid member. The container body has a top opening, which opens upward. The container body is formed as various shapes depending on the applications of the present storage apparatus. The container body is made of resin in general. However, it does not matter at all that the container body is made of any material.
The lid member is for opening and closing the top opening of the container body, and is held swingably to the container body. The lid member is formed in such a size that it can open and close the top opening of the container body. The lid member is provided with an arm, which extends downward from the lid member. Note that the lid member is held swingably to the container body by way of the arm. Moreover, the present storage apparatus further comprises a shaft, and a slot. The shaft is for pivotably supporting the arm to the container body. The pivotably-supporting shaft is fitted into the slot, which extends up-and-downward. Thus, the arm is supported pivotably to the container by way of the shaft, which is fitted into the shaft. Note that the pivotably-supporting shaft can be formed in one of the container body and arm. Accordingly, the slot can be formed in the other one of the container body and arm. Consequently, the pivotably-supporting shaft, which protrudes from one of the container body and arm, is disposed movably in the slot, which is formed in the other one of the container body and arm. For example, when the slot is formed in the arm, the pivotably-supporting shaft, which protrudes from the container body, engages movably with the slot, which is formed in the arm. On the other hand, when the slot is formed in the container body, the pivotably-supporting shaft, which protrudes from the arm, engages movably with the slot, which is formed in the container body.
Therefore, when an excessive load acts onto the closed lid member, the slot and the pivotably-supporting shaft move relatively to each other to move the arm downward. For example, when the arm is provided with the slot, the arm moves so that the pivotably-supporting shaft moves relatively to the slot. On the other hand, when the container body is provided with the slot, the arm moves so that the slot moves relatively to the pivotably-supporting shaft.
In order to control the moving magnitude of the slot or pivotably-supporting shaft, the present storage apparatus comprises the container body, which has a receiver. The receiver is brought into contact with the lid member so as to support the lid member. Therefore, when the lid member is brought into contact with the receiver, the lid member is inhibited from moving any further. Moreover, since the receiver receives the load which the lid member exerts, no excessive load acts onto the arm.
The arm is disposed so as to extend downward from one of the opposite side surfaces of the lid member in general. However, paired arms can preferably be disposed so as to extend downward from the opposite side surfaces of the lid member, respectively. In such a preferable arrangement, since it is possible to provide the opposite-side arms with the above-described slot/supporting structures, respectively, the opposite-side arms can move uniformly even when they are subjected to an excessive load so that they are furthermore inhibited from deforming.
Moreover, at least one of the lid member and container body can preferably be provided with a guide for guiding the swinging cover in order to have the lid member swing stably. If such is the case, it is needed to dispose the guide so as not to inhibit the above-described relative movement of the slot and pivotably-supporting shaft. For example, when the present storage apparatus is constructed so that the container body is provided with a guide groove which engages with a pin protruding from the arm, it is advisable to form a descent groove, which enables the pin to move downward only when the lid member is closed, in the guide groove. In such a preferable arrangement, when an excessive load acts onto the lid member, the pin moves in the descent groove so that the slot and the pivotably-supporting shaft can move relatively to each other.
When no excessive load acts onto the lid member, it is necessary to hold the lid member in such a floating manner that it does not contact with the receiver. Hence, the present storage apparatus comprises an urging member, which urges the lid member upward. The urging member can be made of springs, or elastomers such as rubber and polyurethane. However, it is not preferable if the lid member has descended with a small load. Accordingly, as for the urging member, it is preferable to use springs, which can exert a comparatively large load to the lid member. The urging member can urge the lid member itself, but can preferably urge the arm. Note that it is convenient to utilize the above-described pin for urging the arm upward.
The receiver can be disposed at any position without limitation. However, the receiver can preferably be disposed at positions from above to rearward with respect to the pivotably-supporting shaft, for instance, on an opposite side with respect to the opening opposite end of the lid member. When the present storage apparatus further comprises a push-lock opening device, it is preferable not to dispose the receiver at portions which an operator pushes the lid member to open.
Hereinafter, the present storage apparatus will be described in detail with reference to an example.
The container 1 is made of resin, and is provided with opposite bosses 10. The bosses 10 are formed on both opposite right and left side surfaces of the container 1, respectively, and protrude outward therefrom. Moreover, the container 1 is provided with an engagement pin 11, which is disposed swingably on a lower side of one of the right and left side surfaces of the container 1. In addition, the container 1 opens upward, and is provided with a receiver 12. The receiver 12 protrudes upward beyond the opening of the container 1. Moreover, the receiver 12 is disposed at position, which is placed above the bosses 10 when the container 1 is viewed from one of the opposite sides. In addition, the receiver 12 is formed as an arc shape in cross section so that it does not interfere with the swinging lid member 2.
The lid member 2 is made of resin, and is formed as a plate shape substantially in such a size that it can cover the opening of the container 1. Moreover, the metal-plate arm 3 is fastened to the rear surface of the lid member 2 with screws (not shown). In addition, as shown in
The metal-plate arm 3 comprises paired legs 30, 31, and a bridge 32, and is formed as a letter “U” shape substantially. The bridge 32 connects between the paired legs 30, 31, and is fastened to the lid member 2. The paired legs 30, 31 extend downward from the bridge 32, and are provided with a slot 33, respectively. The slots 33 are formed longer in the top/down direction, and have a width which is narrower than the diameter of the bosses 10. Above the slots 33, a pin 34 protrudes outward, respectively. Note that both of the imaginary line connecting between the paired slots 33 and the imaginary line connecting between the paired pins 34 are formed parallel to the longitudinal direction of the container 1. Moreover, one of the paired legs 30, 31 (e.g. the leg 30) is formed longer downward than the other one of the paired legs 30, 31 (e.g., the leg 31). In addition, a cam 35, which is provided with a heart-shaped cam groove in the bottom surface, is fastened to the leading or lower opposite end of the leg 30. Note that the heart-shaped cam groove of the cam 35 engages with the engagement pin 11 of the container 1.
The cover 4 is made of resin, and comprises a back 40, and paired grips 41, 41. The back 40 is formed as an arc shape in cross section. The grips 41, 41 protrude forward from the opposite ends of the back 40 substantially perpendicularly. The grips 41, 41 are provided with a through hole 42, respectively. Above the through holes 42, a substantially arc-shaped guide groove 43 is formed so as to penetrate through the outer and inner surfaces of the grips 41, 41, respectively. Note that the guide grooves 43 are provided with a descent groove 44, respectively, as shown in
The above-described respective component parts are assembled in the following manner. First of all, the metal-plate arm 3 is fastened to the lid member 2 with screws. Then, the bosses 10 of the container 1 are fitted into the springs 5, respectively. Thereafter, the metal-plate arm 3 is disposed so as to hold the container body 1 between the paired legs 30, 31. In this instance, the slots 33 and the bosses 10 are positioned coaxially. Moreover, the springs 5 are disposed between the container 1 and the metal-plate arm 3 so as to engage with them. Thus, the springs 5 urge the lid member 2 in the direction of opening the opening of the container 1. In addition, the engagement pin 11 is engaged with the cam 35 to make a push-lock mechanism.
Afterward, the cover 4 is disposed so that the paired grips 41, 41 are disposed outside the paired legs 30, 31 of the metal-plate arm 3. In this instance, the cover 4 and the metal-plate arm 3 are disposed so that the pins 34 engage with the guide grooves 43, and that the through holes 42 and the bosses 10 are positioned coaxially. Then, resinous bolts 6 are fitted into the through holes 42, respectively. Finally, the cover 4 is fastened to the container 1 with not-shown screws. Thus, the cover 4 is assembled with the container 1 integrally. Moreover, the lid member 2 comes in and out the space, which is formed between the back 40 of the cover 4 and the container 1. Accordingly, the lid member 2 and metal-plate arm 3 can swing around the resinous bolts 6. In addition, torsion springs 7 are fastened to the cover 4 at one of the opposite ends, respectively, and urge the pins 34, which protrude through the guide grooves 43, upward at the other one of the opposite ends, respectively.
In the thus assembled state shown in
In the thus constructed cup holder according to an example of the present invention, the lid member 2 closes the opening of the container while the engagement pin 11 engages with the cam 35, as shown in
After the operator has completed using the cup holder according to an example of the present invention, he or she presses the leading end of the lid member 2, which protrudes against the urging forces of the springs 5, forward, that is, in the direction of approaching the opening of the container 1. Then, the lid member 2 and metal-plate arm 3 swing in the opposite direction with respect to the above-described direction. When the engagement pin 11 engages with the cam 35, the lid member 2 is held at the position where it closes the opening of the container 1 as shown in
On the other hand, when an excessive load is applied to the lid member 2, which is placed in closing the opening of the container 1, from above, and if the applied excessive load is larger than the forces, which the springs 5 and torsion springs 7 act onto the lid member 2, the resinous bolts 6 move upward relatively within the slots 33, and the pins 34 move downward relatively within the descent grooves 44 as shown in
All in all, the cup holder according to an example of the present invention can operate to open and close the lid member 2 stably, because the metal-plate arm 3 is inhibited from deforming plastically even when the lid member 2 is subjected to an excessive load from above.
The present storage apparatus can be applied to various storage apparatuses as far as they comprise a lid member, and an arm made integrally with the lid member, respectively, wherein the lid member swings to open and close the opening of storage apparatuses.
Having now fully described the present invention, it will be apparent to one of ordinary skill in the art that many changes and modifications can be made thereto without departing from the spirit or scope of the present invention as set forth herein including the appended claims.
