Description

[0001] This application is a divisional application of the invention patent application with the application date of July 16, 2020, the application number of 202010684032.3, and the invention title of "Beverage Container Holding Device". Technical Field

[0002] The present invention relates to a beverage container holding device also known as a cup holder. Background Art

[0003] In a vehicle, particularly a passenger car, a cup holder is provided within the reach of an occupant's hand. For example, when a 350 - millilitre (hereinafter referred to as ml) beverage container is used as the standard - sized container and a 500 - ml beverage container is used as the long - sized container, if the depth of the cup holder corresponds to the standard - sized container, the long - sized container will protrude significantly upward and become unstable. On the other hand, if the depth corresponds to the long - sized container, it is difficult to take out the standard - sized container.

[0004] Therefore, various cup holders capable of corresponding to beverage containers of different sizes have been proposed (for example, refer to Patent Document 1 ( Figure 7 , Figure 8 ).

[0005] Based on Figure 8 to explain Patent Document 1.

[0006] Figure 8 In (a) of Figure 8 is a cross - sectional view of an existing beverage container holding device, and (b) of

[0007] As shown in (a) of Figure 8 , the beverage container holding device 100 mainly includes a cylindrical portion 101, a movable bottom plate 102 that moves up and down within the cylindrical portion 101, and an operating lever 103 for an occupant to operate.

[0008] A claw - ring 105 is rotatably mounted on the lower surface of the movable bottom plate 102. Claws 104 are provided on the claw - ring 105.

[0009] As shown in (b) of Figure 8 , a longitudinally extending guide groove 106 is provided on the cylindrical portion 101. The claws 104 move up and down along the guide groove 106.

[0010] Locking recesses 107 and 108 are provided on one side of the guide groove 106. When the claws 104 are engaged with one of the locking recesses 107 and 108, the movable bottom plate 102 is locked so that it cannot move up and down.

[0011] In Figure 8In (a) of the figure, when the movable bottom plate 102 is at the position indicated by the imaginary line, if the operating lever 103 is manually pressed, the claw ring 105 rotates in the unlocking direction against the force of the torsion spring 109. Then, in Figure 8 In (b) of the figure, the claw 104 fitted in the locking recess 108 is disengaged, rises in the guide groove 106, and is fitted in the locking recess 107, reaching Figure 8 the position indicated by the solid line in (a) of the figure.

[0012] When the beverage container 111 is manually placed down, the movable bottom plate 102 indicated by the solid line descends to the position of the imaginary line and is locked at this position.

[0013] However, since the beverage container holding device 100 is mounted on a passenger vehicle, it is affected by the vibration of the vehicle body. Then, the liquid beverage will spill out of the beverage container 111 at a certain frequency or probability. In addition, when the beverage container 111 is taken out or put in, the liquid beverage may also be accidentally spilled. When the amount of the spilled beverage increases, the liquid beverage will spill out from the edge of the movable bottom plate 102 and flow down in the gap 112 between the cylindrical portion 101 and the movable bottom plate 102.

[0014] As Figure 8 shown in (b) of the figure, a part of the flowing-down liquid beverage flows down along the guide groove 106. Many liquid beverages contain sticky sugars. This sugar will solidify between the locking recesses 107 and 108 and the claw 104. As a result, the claw 104 is fixed at the locking recess 107 or the locking recess 108, and it is difficult to release the lock.

[0015] In addition, the remaining part of the liquid beverage flowing down in the gap 112 will spread to the bottom surface of the movable bottom plate 102 and solidify. Then, the claw ring 105 is fixed on the movable bottom plate 102. As a result, it is even more difficult to release the lock.

[0016] In this way, the beverage container holding device 100 disclosed in Patent Document 1 cannot be said to have a structure that resists the spillage of liquid beverages.

[0017] However, in the process of diversifying the usage modes of the beverage container holding device 100, there is a need for a beverage container holding device with a structure that can resist the spillage of liquid beverages, that is, a beverage container holding device that is not likely to cause operational failures such as difficulty in releasing the lock even if the liquid beverage spills out of the beverage container.

[0020] Patent Document 1: Japanese Patent No. 6071003 Gazette Summary of the Invention

[0021] An object of the present invention is to provide a beverage container holding device that is less likely to cause malfunction even if a liquid beverage spills from a beverage container.

[0022] The invention according to Technical Solution 1 is a beverage container holding device, which includes: a housing member having an upper opening and a lower opening, for housing a beverage container inserted through the upper opening; a movable bottom plate movably mounted on the housing member to support the bottom of the beverage container; a movable bottom plate biasing member disposed between the housing member and the movable bottom plate to bias the movable bottom plate upward; a movable bottom plate locking mechanism for fixing the movable bottom plate at a predetermined height against the biasing force of the movable bottom plate biasing member; a locking release member for releasing the locking of the movable bottom plate locking mechanism; and a bottom member for closing the lower opening, characterized in that

[0023] the housing member has a guiding groove extending longitudinally.

[0024] the movable bottom plate has a branch portion extending through the guiding groove to the outside of the housing member and a claw portion horizontally extending from the branch portion.

[0025] the movable bottom plate locking mechanism includes: an annular member rotatably mounted below the bottom member; a column member extending upward from the annular member parallel to the guiding groove; and a locking piece integrally formed on the column member for pressing the upper surface of the claw portion.

[0026] When viewed from the center of the housing member, the claw portion engages with the movable bottom plate locking mechanism at a position where it cannot be seen through the guiding groove.

[0027] The invention according to Technical Solution 2 is based on the beverage container holding device according to Technical Solution 1, and is characterized in that

[0028] the movable bottom plate locking mechanism is held on the housing member by means of an arcuate long hole and a pin inserted into the arcuate long hole.

[0029] The invention according to Technical Solution 3 is based on the beverage container holding device according to Technical Solution 1 or 2, and is characterized in that

[0030] the upper ends of the column members are connected to each other by a connecting member.

[0031] The invention according to Technical Solution 4 is based on the beverage container holding device according to Technical Solution 1 or 2, and is characterized in that

[0032] the bottom member has a vertical water guiding portion continuous with the guiding groove.

[0033] The invention of Technical Solution 5 is based on the beverage container holding device described in any one of Technical Solutions 1 to 3, and is characterized in that

[0034] The bottom member is provided with a vertical water guiding portion continuous with the guiding groove.

[0035] The invention of Technical Solution 6 is based on the beverage container holding device described in Technical Solution 1, and is characterized in that

[0036] A drain tube member is provided on the bottom member, and the movable bottom plate locking mechanism is supported by a locking mechanism support member so as to be rotatable, and the drain tube member extends below the locking mechanism support member.

[0037] The invention of Technical Solution 7 is based on the beverage container holding device described in Technical Solution 6, and is characterized in that

[0038] Engaging pieces are formed on the drain tube member, and the engaging pieces are engaged with the locking mechanism support member.

[0039] In the invention of Technical Solution 1, when viewed from the center of the housing member, the claw portion is engaged with the movable bottom plate locking mechanism at a position where it cannot be seen through the guiding groove.

[0040] A part of the spilled liquid beverage flows out of the housing member through the guiding groove. Since the engaging portion between the claw portion and the movable bottom plate locking mechanism is at a position where it cannot be seen through the guiding groove, the liquid beverage does not contact the engaging portion. The engagement between the claw portion and the movable bottom plate locking mechanism maintains a sound operation.

[0041] Therefore, according to the present invention, there is provided a beverage container holding device that is not easily prone to operation failure even if liquid beverage spills from the beverage container.

[0042] In the invention of Technical Solution 2, the movable bottom plate locking mechanism is held by the circular arc elongated hole and the pin inserted into the circular arc elongated hole in the housing member. Since it is held by the housing member, vibration (horizontal vibration) of the movable bottom plate locking mechanism can be suppressed.

[0043] In the invention of Technical Solution 3, the upper ends of the column members are connected to each other by a connecting member. Assuming that the upper ends of the column members are free, the upper ends are easily deflected.

[0044] In the present invention, since the upper ends are connected by a connecting member, deflection of the upper ends of the column members can be suppressed.

[0045] In the inventions of Technical Solutions 4 and 5, the bottom member is provided with a vertical water guiding portion continuous with the guiding groove. It is possible to make the liquid beverage flow to the vertical water guiding portion and prevent the liquid beverage flowing along the guiding groove from spreading to the lower surface of the bottom member.

[0046] In the invention of Technical Solution 6, the liquid beverage accumulated on the bottom member can be quickly discharged through the drain tube member. In addition, since the drain tube member extends below the locking mechanism support member, the liquid beverage is less likely to spread to the locking mechanism support member.

[0047] In the invention of Technical Solution 7, since the locking mechanism support member is supported by the engaging piece, the swaying of the locking mechanism support member is suppressed. In addition, since the locking mechanism support member is temporarily fixed by the engaging piece, the screwing operation becomes easier. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Implementation Modes

[0058] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0059] [Embodiment]

[0060] As Figure 1 shown, the beverage container holding device 10 is such a cup holder that has a gourd-shaped upper opening 11 at the upper part, and a cylindrical beverage container ( Figure 5 , reference numeral 15) can be taken out and put in through the upper opening 11. In addition, the beverage container holding device 10 of the present invention can also be a cup holder for holding one beverage container. In this case, the upper opening 11 becomes circular.

[0061] In addition, the cylindrical beverage container ( Figure 5 , reference numeral 15) can also be a square tube. In this case, the upper opening becomes a square gourd shape with a reduced diameter in the middle of two quadrilaterals. The square tube-shaped beverage container holding device 10 can also be a holder for holding one beverage container. In this case, the upper opening 11 becomes a quadrilateral.

[0062] A decorative ring 12 is inlaid in a manner surrounding the upper opening 11. An upper panel 13 is placed below the decorative ring 12, and a locking release button 72 as a locking release member is arranged on the upper panel 13. The function of the locking release button 72 will be described in Figure 7 below.

[0063] Hereinafter, the structure of each part will be described according to Figures 2 to 7 the following.

[0064] As Figure 2 shown, the housing member 20 is composed of an upper cylinder 21 and a lower cylinder 22.

[0065] In this example, the lower cylinder 22 is composed of a half body 22a and a half body 22b formed by splitting in half. That is, by combining the half body 22b with the half body 22a and binding them with a first screw 24, a cylinder is formed. In addition, the half body 22a and the half body 22b can also be combined by claws and holes. In addition, the lower cylinder 22 can also be an undivided cylinder.

[0066] The lower cylinder 22 has three guide grooves 23 extending longitudinally.

[0067] The cylindrical lower cylinder 22 is combined with the upper cylinder 21 and bound with a second screw 25. Thus, the housing member 20 with an upper opening 11 and a lower opening 26 is obtained.

[0068] The movable bottom plate 40 is housed in such a housing member 20 so as to be movable up and down.

[0069] The movable bottom plate 40 includes: a circular plate portion 41; a branch portion 42 that horizontally extends outward from the circular plate portion 41; a claw portion 43 that extends from the branch portion 42; and a vertically long shielding portion 44 that extends upward from the branch portion 42. The claw portion 43 extends substantially parallel to the outer edge of the circular plate portion 41.

[0070] A tension spring serving as a movable bottom plate biasing member 46 is installed between the movable bottom plate 40 and the upper cylindrical body 21. That is, with the branch portion 42 passing through the guide groove 23, the movable bottom plate 40 is biased upward.

[0071] In addition to the tension spring, the movable bottom plate biasing member 46 can also be a rubber cord, a torsion spring, a compression spring. In short, as long as it is a member that biases the movable bottom plate 40 upward, the type is not limited.

[0072] In addition, the number and positions of the guide groove 23, the branch portion 42, and the movable bottom plate biasing member 46 are arbitrary.

[0073] As Figure 3 shown, the lower opening portion 26 of the lower cylindrical body 22 is closed by a bottom member 48. The bottom member 48 is coupled to the lower cylindrical body 22 with a third screw 49.

[0074] In addition, the lower cylindrical body 22 has an outwardly projecting piece 27 at its upper edge, and an arcuate long hole 28 is provided in the projecting piece 27.

[0075] Regarding the movable bottom plate locking mechanism 60, its structure will be described in detail later in Figure 4 The movable bottom plate locking mechanism 60 has a pin 61 on its upper surface and an annular member 62 at its lower part.

[0076] Such a movable bottom plate locking mechanism 60 is rotatably supported by a locking mechanism support member 50 that also serves as a cover member. Specifically, a circular peripheral wall portion 51 is provided on the locking mechanism support member 50, and the annular member 62 is rotatably fitted on the peripheral wall portion 51.

[0077] The movable bottom plate locking mechanism 60 is biased toward the locking side by a torsion spring 53.

[0078] And the movable bottom plate locking mechanism 60 is nested in the lower cylindrical body 22 in such a way that the pin 61 is inserted into the arcuate long hole 28. Then, the locking mechanism support member 50 is coupled to the bottom member 48 with a fourth screw 54.

[0079] According to Figure 4 to describe the structure of the movable bottom plate locking mechanism 60.

[0080] As Figure 4As shown in (a) therein, the movable bottom plate locking mechanism 60 has: an annular member 62; three column members 63 extending upward from the annular member 62; locking pieces 64 and 65 integrally formed on each of these column members 63; a connecting member 66 connecting the upper ends of the column members 63 to each other; and pins 61 erected on the upper surfaces of the column members 63.

[0081] In addition, the connecting member 66 is in a C shape in this embodiment, but is formed in an O shape (ring shape) when the housing member 20 is a simple cylinder.

[0082] In addition, the locking pieces 64 and 65 are two in this embodiment, but may be only one or more than three.

[0083] In addition, the connecting member 66 may be omitted from the movable bottom plate locking mechanism 60 to achieve weight reduction. Figure 4 The movable bottom plate locking mechanism 60B with the connecting member 66 omitted is illustrated by (b) therein.

[0084] That is, as Figure 4 shown in (b) therein, the movable bottom plate locking mechanism 60B has: an annular member 62; a column member 63 extending upward from the annular member 62; locking pieces 64 and 65 integrally formed on the column member 63; and pins 61 erected on the upper surface of the column member 63.

[0085] Since the movable bottom plate locking mechanism 60B does not have the connecting member 66, it achieves weight reduction accordingly. On the contrary, since the column member 63 is a cantilever beam, the deflection of the upper end of the column member 63 is likely to become large.

[0086] Regarding this point, if it is the structure of (a) therein, the connecting member 66 is used to suppress the deflection of the upper end of the column member 63. Figure 4 As

[0087] shown, the movable bottom plate 40 is housed in the housing member 20 composed of the upper cylinder 21 and the lower cylinder 22 so as to be movable up and down. The movable bottom plate 40 supports the bottom of the so-called long beverage container 15. Figure 5 The annular member 62 rotates around the peripheral wall portion 51, and the connecting member 66 rotates around the lower cylinder 22.

[0088] In addition, in the embodiment, the housing member 20 is divided vertically, but the housing member 20 may also be a single cylinder as long as it can be formed.

[0089] As

[0090] shown, the movable bottom plate 40 is urged upward by the movable bottom plate urging member 46. The guide groove 23 is covered by the longitudinally long covering portion 44. Figure 6 The annular member 62 rotates around the peripheral wall portion 51, and the connecting member 66 rotates around the lower cylinder 22.

[0091] As Figure 7 shown, when viewed from the outside, the claw portion 43 and the movable bottom plate locking mechanism 60 are disposed at positions away from the guide groove 23. That is, since the center of the housing member 20 is located on the inner side of the figure, when viewed from the center of the housing member 20 (from the inner side of the figure to the front side of the figure), the claw portion 43 and the movable bottom plate locking mechanism 60 are arranged at positions where they cannot be seen through the guide groove 23.

[0092] In addition, the movable bottom plate locking mechanism 60 has an inclined cam surface 67 near one of the plurality of column members 63 (diagonally upward to the right in the figure).

[0093] In addition, a release lever 70 extending upward is disposed near the cam surface 67.

[0094] The release lever 70 is formed with a cam portion 71 placed on the cam surface 67 at the lower portion. The lower end of the release lever 70 is supported by the locking mechanism support member 50 so as to be movable up and down. In addition, the upper portion of the release lever 70 is supported by the upper cylinder 21 so as to be movable up and down. A locking release button 72 is inserted into the upper end of the release lever 70, and the release lever 70 is biased upward by a biasing member 73 such as a compression spring.

[0095] In addition, the locking release member is not limited to the locking release button 72, and may also be the release lever 70 itself.

[0096] When the locking release button 72 is manually pressed, the cam surface 67 is pushed by the cam portion 71, and the movable bottom plate locking mechanism 60 moves in the locking release direction (right side in the figure).

[0097] In addition, the locking release button 72 may also be provided on the side wall of the upper cylinder 21. Although the movement of the locking release button is in the horizontal direction, it is only necessary to provide a mechanism that converts the horizontal movement into an up and down movement via a link or the like.

[0098] In the figure, the claw portion 43 engages with the lower locking piece 65. That is, the locking piece 65 presses the upper surface of the claw portion 43. As a result, the movable bottom plate ( Figure 6 , reference numeral 40) biased upward by the movable bottom plate biasing member 46 is locked at this position.

[0099] Next, when the locking release button 72 is pressed, the movable bottom plate locking mechanism 60 moves in the locking release direction (right side in the figure), and the lower locking piece 65 separates from the claw portion 43. Then, by the movable bottom plate biasing member 46, the claw portion 43 moves upward and moves to the upper edge of the guide groove 23. As a result, as Figure 5 shown, the upper portion of the beverage container 15 protrudes greatly and is easy to grasp.

[0100] Although the illustration is omitted, when the beverage container 15 is of a standard size, the claw portion 43 hangs on the upper locking piece 64. Similarly in this case, if the lock release button 72 is pressed, the claw portion 43 rises and moves to the upper edge of the guide groove 23.

[0101] In addition, among beverage containers, there are paper cups (or plastic cups) with the entire upper surface open. In a cup, the filled liquid beverage is likely to spill. A part of the spilled liquid beverage flows from the inner side of Figure 7 to the front side through the guide groove 23. At this time, the claw portion 43 and the locking pieces 64, 65 are located at positions away from the guide groove 23. As a result, the spilled liquid beverage does not come into contact with the claw portion 43 or the locking pieces 64, 65.

[0102] Moreover, the spilled liquid beverage flows down in the vertical water guide portion 75 connected to the lower end of the guide groove 23.

[0103] In Figure 6 , due to the presence of the vertical water guide portion 75, the spread of the spilled liquid beverage to the lower surface of the bottom member 48 is prevented. Also, since the vertical water guide portion 75 is located outside the locking mechanism support member 50 and the annular member 62 of the movable bottom plate locking mechanism, the liquid beverage flowing down in the vertical water guide portion 75 does not spread to the locking mechanism support member 50 and the annular member 62.

[0104] In addition, as Figure 5 shown, a drain tube member 55 is provided on the bottom member 48, and the liquid beverage can be quickly discharged. Also, since the drain tube member 55 extends below the locking mechanism support member 50, the liquid beverage is even less likely to spread to the locking mechanism support member 50 and the annular member 62.

[0105] In addition, a engaging piece 56 is formed on the drain tube member 55. The engaging piece 56 engages with the locking mechanism support member 50.

[0106] As described above, the locking mechanism support member 50 is joined to the bottom member 48 with the fourth screw 54. There is a concern that the locking mechanism support member 50 swings around the fourth screw 54. However, since the locking mechanism support member 50 is supported by the engaging piece 56, the swinging of the locking mechanism support member 50 is suppressed.

[0107] In addition, the locking mechanism support member 50 is supported by the engaging piece 56. Then, the fourth screw 54 is screwed into the bottom member 48. That is, since the locking mechanism support member 50 is temporarily fixed by the engaging piece 56, the screwing operation becomes easy. As a result, the joining operation of the locking mechanism support member 50 to the bottom member 48 becomes easy.

[0108] The sticky liquid beverage does not come into contact with the claw portion 43 and the locking pieces 64, 65, and does not spread to the locking mechanism support member 50 and the annular member 62. Therefore, the operation of the movable bottom plate locking mechanism 60 becomes smooth, and locking and unlocking can be performed smoothly.

[0109] When the movable bottom plate locking mechanism 60 rotates, since the pin 61 is guided by the arcuate long hole 28, the movable bottom plate locking mechanism 60 rotates without wobbling. Therefore, the good operation of the movable bottom plate locking mechanism 60 is maintained.

[0110] In addition, the pin 61 can also be provided on the lower cylindrical body 22, and the arcuate long hole 28 can be provided on the column member 63 side. In addition, the arcuate long hole 28 through which the pin 61 passes can also be an arc groove only for the pin 61 to be inserted.

[0111] In addition, not only cylindrical, as long as the pin 61 is formed to be able to slide in the arcuate long hole 28.

[0112] In addition, the beverage container holding device 10 of the present invention is preferably applicable to a passenger car, but can also be applicable to land vehicles such as trucks or buses, airplanes, and ships. However, it is more preferably applicable to vehicles assuming sudden starts or sudden brakes.

[0113] The beverage container holding device of the present invention is preferably applicable to a vehicle.
