Cell phone stand

Abstract

A cell phone stand has a base and a cell phone mounting bracket rotatably affixed to the base around a horizontal axis. The mounting bracket has a first jaw and a second jaw that is movable in a horizontal direction with respect to the first jaw. The first jaw has a first u-shaped channel with a first upper segment and a first lower segment. The second jaw has a second u-shaped channel with a second upper segment and a second lower segment. By adjusting the position of the jaws, the user may adjust a width between the first and upper segments, thus sizing the mounting bracket to receive a cell phone of a particular width. Even at the smallest such width, inner ends of the first and second lower segments of the u-shaped channels remain spaced from each other so as to permit the cell phone to be connected to an electrical cable while being held by the stand.

DETAILED DESCRIPTION

(14) Referring first to FIG. 1, a stand 100 according to the invention has two main parts: a cell phone mounting bracket 102 and a base 104. The base 104 is generally oriented around a vertical axis X. A body 801 of the base 104 has a top end 106 that is disposed above a bottom end 108. A mounting pier 110 upwardly extends from the top end 106. In one embodiment, the base 104 includes first, second and third legs 112, 114 and 116, which in general radially outwardly extend from the vertical axis X and which in this embodiment are separated from each other by 120 degrees. While the base 104 could have four or more legs, three are preferred, as they help unambiguously define three points of a plane occupied by the foot gripping surfaces (later described). Four or more legs might introduce wobbling, particularly if the base 104 is placed on a surface that is uneven or not completely planar.

(15) The bracket 102 is rotatably affixed to the mounting pier 110 around a horizontal axis Y. In one embodiment the mounting pier has at least one, and in this embodiment three, upstanding pier plates 118, 120 and 122, each of which have a length and a width greater than their thickness (the thicknesses being in a direction parallel to axis Y) and each of which is disposed to be parallel to and spaced from the others. Body 801, including legs 112-116 and the mounting pier plates 118-122, can be integrally injection-molded of a tough plastic such as ABS.

(16) The cell phone mounting bracket 102 has a first jaw 124 and a second jaw 126. In the illustrated embodiment the second jaw 126 is disposed on the left side of the bracket 102 and is movable, in a direction parallel to axis Y, towards and away from the first jaw 124, which in this embodiment is stationary.

(17) The first jaw 124 includes a first back plate 128 that aids in the support of a back of a cell phone and generally resides in a plane, the angle of which may be adjusted by the user relative to axis Y. A first u-shaped channel 130 forwardly extends from a margin of the first back plate 128, in a direction orthogonal to the plane occupied by back plate 128. The first u-shaped channel has a channel bottom 132 disposed to be orthogonal to first back plate 128 and an outer lip 134 disposed to be in a plane parallel to, but spaced forwardly of, the first back plate 128. A depth of the first u-shaped channel 130 is selected to accommodate most current cell phones, and in some embodiments may be specified so as to further accommodate the jackets with which users frequently encase their cell phones.

(18) The second, movable jaw 126 includes a second back plate 136 that also aids in the support of the back of the cell phone. The second back plate 136 resides substantially in the same plane as that occupied by first back plate 128, although parts of it slide over parts of the first back plate 128, as will be later described. A second u-shaped channel 138 of jaw 126 forwardly extends from the second back plate 136, in a direction orthogonal to the plane occupied by back plate 136. The second u-shaped channel 138 has a channel bottom 140 disposed to be orthogonal to the second back plate 136, and an outer lip 142 disposed to be in a plane parallel to, but spaced forwardly of, the second back plate 136. A depth of the second channel bottom 140 may match the depth of channel bottom 132 and should be selected to accommodate a variety of cell phones, jacketed and unjacketed.

(19) The first u-shaped channel 130 has a first upper segment 144 disposed in a plane that is parallel to axis X, and a first lower segment 146 disposed in a plane that is parallel to axis Y. In use, the first upper segment 144 will be oriented in an inclined plane relative to the horizontal, and most of the time will be oriented so as to be at an angle to vertical axis X. The first upper segment 144 and the first lower segment 146 may be joined by a curved transition 148.

(20) Similarly, the second u-shaped channel 138 has a second upper segment 150 disposed to be in substantially the same inclined plane occupied by first upper segment 144, and a second lower segment 152 disposed in a plane that is parallel to horizontal axis Y. Second segments 150 and 152 may be joined by a curved transition 154. The first upper segment 144 and the second upper segment 150 have open sides and bottoms that face each other, and their separation from each other defines a width which may be adjusted to receive a cell phone of a particular width. On the other hand, the first lower segment 146 and the second lower segment 152 are aligned to each other, and their bottoms and openings face the same, generally upward direction. As shown in FIG. 4, first and second lower segments 146 and 152 support the bottom of the cell phone C.

(21) FIG. 2 shows the cell phone mounting bracket 102 in a smallest width position, in which the inwardly facing surface of the bottom of second upper segment 150 is spaced by a width W.sub.1 from the inwardly facing surface of the bottom of first upper segment 144. This closed or minimum-width position accommodates cell phones of a small width. The outer or forward lip 134 of the first u-shaped channel 130, and most of the bottom 132 of the first u-shaped channel 130, terminate at an inner end 200. Similarly, the outer or forward lip 142, and most of the bottom 140, of the second u-shaped channel 138, terminate at an inner end 202. Even in the closed position shown here, the horizontal channel segment ends 200 and 202 leave a hole or opening 204 for the insertion of a cell phone electrical cable 400 (see FIG. 4), such as a firewire cable, into a port in the bottom of cell phone C.

(22) FIG. 3 is a view similar to FIG. 2, but showing movable jaw 126 at a second and maximum-width W2 at which the bottom of its channel upper segment 150 is spaced farthest away from the bottom of first channel upper segment 144. This second position accommodates cell phones of a relatively large width. As seen in FIG. 4, and once the width between the jaws 124, 126 has been appropriately adjusted, the lips 134, 142 of the u-shaped channels 130, 138 prevent the cell phone C from falling out of the mounting bracket 102.

(23) Returning to FIG. 2, the cell phone mounting bracket 102 is supported on base 104 by a right support plate 206 and a left support plate 208. Support plates 206 and 208 can be integrally molded with, and can downwardly extend from, the first, stationary jaw 124. Support plates 206 and 208 are generally flat and occupy vertical planes that are orthogonal to the axis Y and are parallel to each other. As assembled to the mounting pier 110, support plate 206 occupies the space between pier plates 118 and 120, while support plate 208 occupies the space between pier plates 120 and 122. While in other embodiments a single support plate could be rotatably affixed to a single pier plate, the provision of multiple pier plates and support plates increases the rigidity and strength of the articulated structure. As unclamped, the surfaces of support plates 206, 208 slide past adjacent surfaces of pier plates 118, 120 and 122, but as clamped, the support plates 206 and 208 and pier plates 118, 120 and 122 afford large surface areas through which large frictional forces may be generated by compression.

(24) The bottom end 108 of the base 104 has a lower margin 210 that, in this embodiment, occupies a horizontal plane. Each of the legs 112, 116, 118 terminates in a foot 212, 214, 216 that is equipped with a respective gripping member 218, 220 or 222 (only feet 212, 216 are visible in FIG. 2; see, e.g., FIG. 8 for foot 214). The bottom or contact surfaces 224, 226 (FIG. 8) and 228 of respective gripping members 218, 220 and 222 are disposed in a plane 230 that is downwardly displaced from the bottom margin 210. The gripping members 218-222 can be formed of a material with a coefficient of friction, relative to the surface on which stand 100 is to be placed, that is higher than the coefficient of friction of the material making up base body 801. For example, gripping members 218-222 can be formed of an elastomer, and more particularly can be molded of a thermoplastic elastomer (TPE). The downward displacement of contact surfaces 224-228 from bottom body margin 210 ensures that the contact surfaces 224-228 will fully support the combined weight of the stand 100 and the cell phone C, and that none of this weight will be borne by bottom body margin 210. This optimizes the gripping action of members 218-222.

(25) FIG. 6 best shows the articulation of the cell phone bracket 102 around mounting pier 110. By clamping and unclamping the pier clamping screw 600, the user may adjust the angle of the cell phone screen for optimum visibility. An alternative angular position of the cell phone mounting bracket 102, and therefore of the cell phone that it holds, is seen in this FIG. 1n dotted line.

(26) Referring to FIG. 8, a body 801 of the stand base 104 conveniently may be injection-molded of plastic, and where injection molding is used as a fabrication technique, the base body 801 should have a sidewall 800 that at least roughly conforms to a nominal thickness throughout the part. This means that the body 801 will have a downward-facing cavity 802. Cavity 802 radially extends into each foot 212, 214, 216, where it is made to house respective gripping members 218, 220 and 222. The bodies of the gripping members 218-222 may each be adhered or otherwise fastened to the interiors of respective cylinders 804 that in turn downwardly depend from, and are molded extensions of, the base sidewall 800. In an alternative embodiment (not shown), the body 801 of the stand base 104 may be machined out of a solid block of aluminum or other metal, filling in cavity 802 except for the interiors of cylinders 804 or their equivalents.

(27) Further details of the illustrated embodiment are revealed by FIG. 10. The right pier plate 118 has been thickened so as to define a hexagonally shaped opening 1000 that closely receives a hex head 1002 of the pier clamping screw 600, thereby preventing a threaded clamping screw shaft 1004 from turning. Shaft 1004 is inserted through coaxial bores made in plates 118, 206, 120, 208 and 122, in that order. A fluted knob 1006, which may be fabricated with nylon and which may have a threaded metal insert 1008, is threaded onto threaded shaft 1004. Tightening knob 1006 will compress bracket support plates 206 and 208 between pier plates 118, 120 and 122, clamping in place the stationary jaw back plate 128 relative to axis Y and controlling one axis of adjustment of the cell phone screen relative to the user.

(28) As best seen in FIG. 10, movable back plate 136 includes a relatively thin, rightward extending tongue 1010 that reciprocates within a shallow and wide horizontal slot 1012 defined by stationary back plate shoulder portions 1014 and 1016. An upper edge 1018 of tongue 1010 is parallel to axis Y and linear, and slides along lower edge 1020 of upper shoulder 1014. Lower edge 1020 of stationary back plate upper shoulder portion 1014 is linear and is aligned with axis Y. A lower edge 1022 of tongue 1010 is parallel to axis Y and linear, and slides along upper edge 1024 of stationary back plate lower shoulder portion 1016. Upper edge 1024 is also linear and is parallel to axis Y.

(29) As seen in FIGS. 5, 9, 11 and 12, the movable jaw 126 has a thickened boss 900 with horizontal and parallel sides that slide within a depression 1026 (FIG. 10) in the stationary jaw 124. Centered within this depression 1026 is a slot 1028, elongate in the horizontal direction, which slidably receives a shaft 1030 of a cap screw 1032. Shaft 1030 is inserted into bore 1033 formed in back plate 136 and then through horizontal slot 1028. A hexagonally shaped cavity 1034 is formed in a forward surface 1036 of the movable jaw back plate portion 136. Cavity 1034 closely receives a hex head 1038 of the cap screw 1032. This prevents cap screw 1032 from turning. A jaw width adjusting knob 1040 may be formed of nylon with a threaded metal insert 1042 and is threaded onto the shaft 1030.

(30) In use, the user slides the movable jaw 126 leftward or rightward relative to stationary jaw 124 to best fit a width of the user's cell phone, then tightens the knob 1040 on threaded shaft 1030 of screw 1032, thereby clamping movable jaw 126 to stationary jaw 124. Boss 900, depression 1026, cap screw 1030 and knob 1040 constitute a jaw clamp for clamping the movable jaw 126 to the stationary jaw 124, but this clamping action could be effected by other means or hardware.

(31) Once the cell phone stand 100 has been adjusted for a particular cell phone and adjusted to optimize the direction in which the cell phone screen faces, it can be left in this condition. The user may at any time slip his or her cell phone into bracket 102, and then later easily remove the cell phone from stand 100 through the open top of bracket 102, with only one hand. The u-shaped cord opening 204, since it is open toward its front and top, permits the cell phone and cord to be extracted and installed as a unit without disconnecting the power/communications cord 400.

(32) In summary, a new cell phone stand has been illustrated and described. A movable jaw allows easy adjustment to a particular cell phone width and a horizontal axis allows easy adjustment of the cell phone viewing angle. Both of these adjustments may be made with one hand. The open tops of the cell phone bracket and the cord channel permit easy insertion and extraction of the cell phone and power cord as a unit, also with a single hand.

(33) While illustrated embodiments of the present invention have been described and illustrated in the appended drawings, the present invention is not limited thereto but only by the scope and spirit of the appended claims.
