Description

The present invention relates to a stand that holds books, tablets, smartphones, etc.

Conventionally, there are various stands that can be placed on a table or desk to hold books, tablets, smartphones, etc. upright. For example, a multi-stand for study has been proposed that can be folded and carried around, and can also hold books or tablets upright (see, for example, Patent Document 1).

Special table 2018-518342 publication

However, while the above-mentioned multi-stand for learning can hold books and tablets upright and can be folded and carried when not in use, the parts that support the front and back covers of books are small, making it difficult to hold them stably and making it impossible to stand up items of different sizes, such as smartphones, which are smaller than books and tablets.

The present invention therefore aims to provide a stand that can stably prop up and hold objects of different sizes, such as books, tablets, and smartphones, and that can be transformed into a small, easy-to-carry stand when not in use.

In view of the above-mentioned problems, the present invention provides a stand body that supports a supported object by leaning it against it, and legs that support the stand body at an angle,
The stand main body is characterized by having a pair of left and right top members that abut and support the held object, a back member that accommodates the legs and has a guide portion that guides a protrusion portion formed on the back side of the top member , a receiving base that supports the lower part of the held object, and an expansion means that expands the top member in the left-right direction relative to the back member.

In addition to the above-mentioned configuration, the deployment means includes a fixed portion provided on the back side of the top surface member,
A horizontally elongated opening portion in the rear member;
a fastener for fastening the fastening portion of the top surface member through the opening portion of the back surface member,
It is preferable that the top surface member be slidable in the left-right direction.

In addition to the above-mentioned configuration, the receiving base is preferably recessed into a recess provided below the top surface member, and has a placement portion for placing the lower part of the object to be held, an insertion portion extending from the placement portion toward the rear side and inserted into the vertical groove of the recess, an axle portion provided to the side of the insertion portion and supported by a bearing portion provided on the side of the vertical groove of the recess, and a lifting means for lifting the receiving base in the vertical direction relative to the recess.

In addition to the above-mentioned configuration, it is preferable that the lifting means be configured so that when the receiving base is tilted relative to the recess in the top surface member, the inclined surface of the insertion portion and the bottom surface of the vertical groove are parallel, and the central axis of the shaft portion of the receiving base coincides with the central position of the long hole in the bearing portion of the recess, allowing the receiving base to be freely raised and lowered in the vertical direction.

The present invention described above makes it possible to provide a stand that can hold objects of different sizes, such as books, tablets, and smartphones, by leaning them up against the surface, and that can be transformed into a small, easy-to-carry stand when not in use.

FIG.

An embodiment of the present invention will be described in detail with reference to Figures 1-8. In this embodiment, the object to be supported by the stand is a book, tablet, smartphone, etc.

As shown in FIG. 1, the stand of the present invention comprises a stand body 10 that holds an object to be held by leaning it against it, and legs 20 that support the stand body 10 at an angle. The stand body 10 has a pair of left and right top members 110, 110 that abut against and support the object to be held, a back member 120 that houses the legs 20, a support pedestal 130 that supports the lower part of the object to be held, and an unfolding means that unfolds the top members 110, 110 in the left-right direction relative to the back member 120.

(Regarding the stand body 10)
The top surface members 110, 110 have, on the front side against which the held object is leaned, a flat support portion 111 against which the held object is leaned, and, on the back side facing the back surface member 120, a plurality of protrusions 112, 112 for improving strength, a finger grip portion 113 formed in a curved concave shape in the center of the support portion 111, and a recess 114 into which the receiving base 130 is recessed.

The support portion 111 has a flat surface 111a that contacts the back surface of the object to be held, and a curved surface 111b on the side edge side of the flat surface 111a.

As shown in FIG. 2(b), the protrusion 112 has a fixed portion 112a that is fixed by a fixing device 121 through the openings 122, 122 of the back member 120. More specifically, if the fixing device 121 is a fixing screw, a screw hole is formed.

The flat surface 111a is a vertically long rectangle, and preferably has a vertical width sufficient to contact at least the entire height of the back surface of the object to be held.

The finger hook portion 113 is formed in a rounded semicircular concave shape, which guides the fingertip to the center of the finger hook portion 113 when pushing it in the left-right direction, making it easier to slide the top surface members 110, 110 in the left-right direction using the deployment means of the stand main body 10.

As shown in Figures 3 and 4, the recess 114 is shaped so that it can recess the entire receiving base 130 and accommodate it so that the flat surface 111a of the support portion 111 and the underside of the receiving base 130 are flush with each other. When the receiving base 130 is roughly rectangular, the recess 114 is formed in a roughly rectangular recess that is one size larger, and vertical grooves 114a, 114a are formed into which the insertion portions 132, 132 of the receiving base 130 are inserted, and the side of the vertical groove 114a has a bearing portion 114b that supports the shaft portion 132b of the receiving base 130.

In addition, this recess 114 has a step 114e on the upper side edge so that the receiving base 130 can be easily rotated in the front direction by hooking a fingertip thereon, and horizontal grooves 114f, 114f formed to insert and support the rear side of the mounting portion 131 of the receiving base 130 near the engagement holes 114d, 114d of the bearing portion 114b described below.

The bearing portion 114b has an elongated hole 114c that allows the receiving base 130 to be raised and lowered in the vertical direction, and engagement holes 114d, 114d at the upper and lower ends of the elongated hole 114c that determine the raised and lowered position of the receiving base 130, and is formed to be wider in the front direction than the elongated hole 114c.

As shown in Figures 2 and 5, the back surface member 120 has openings 122, 122 for fixing the top surface members 110, 110 via a fastener 121, a guide portion 124 for guiding the protrusion portion 112 to prevent the top surface members 110, 110 from wobbling, and a notch 125 on the back surface side for receiving and accommodating the leg 20.

The back member 120 has a recess 126 (see FIG. 1) near the central openings 122 of the back member 120 into which the protruding pieces 111c protruding from the outer frame of the top members 110, 110 fit, in order to give the top members 110, 110 a clicking sensation when returning the top members 110, 110 to their unfolded state in the left-right direction, and a protruding portion 123 formed in a substantially rectangular column shape of about the same width near the lower side of the openings 122 on the front side of the back member 120 to prevent rattling even while sliding the top member 110 to unfold it. The back member 120 also has a vertically long groove-shaped central recess 127 from the upper edge to the lower edge of the back member 120 near the center located at the spine of the book when the object to be held is a book.

As shown in Figures 1 and 2, the openings 122, 122 are formed by drilling long horizontal holes from near the center of the back member 120 to the outer edge in the left-right direction, and at least two openings are formed in parallel in the vertical positions to prevent rattling for one top surface member 110, 110.

The guide portion 124 has a pair of erected pieces 124a, 124a erected from the periphery of the opening portion 122, 122 so as to sandwich the protrusion portion 112, 112 of the top surface member 110, 110, and the width between the erected pieces 124a, 124a is formed so as to gradually narrow relative to the protrusion portion 112 of the top surface member 110, 110 as it advances toward the side edge in the left-right direction.

The deployment means of the stand main body 10 is composed of a fixed part 112a provided on the back side of the top surface members 110, 110, horizontally elongated openings 122, 122 in the back surface member 120, and a fixing device 121 that fixes the fixed part 112a of the top surface members 110, 110 via the openings 122, 122 of the back surface member 120, and the top surface members 110, 110 are in sliding contact with the back surface member 120 while the fixing device 121 moves within the openings 122, 122, thereby sliding and deploying.

As shown in FIG. 3, the support 130 has a mounting portion 131 on which the lower part of the object to be held is placed, insertion portions 132, 132 extending rearward from the mounting portion 131 and inserted into the vertical groove portion 114a of the recess 114, shaft portions 132b provided on the sides of the insertion portions 132, 132, a pressing portion 133 in front of the mounting portion 131 that presses the lower front part of the object to be held, and a lifting means that allows the support 130 to be raised and lowered freely in the vertical direction relative to the recess 114 of the top surface members 110, 110.

The mounting portion 131 is at least a flat plate-like body, and has a protrusion 131a on the side of the flat plate-like body that engages with the recess 114.

The insertion portions 132, 132 are formed in a generally trapezoidal shape with an inclined surface 132a at a predetermined inclination angle θ so as to slide against the bottom surface 114g of the vertical groove portion 114a of the recess 114 in the lifting means of the receiving table 130 described below.

The pressing part 133 is a rod-shaped body having a roughly rectangular prism shape, one end of which is fixed to the front side of the mounting part 131 so as to be freely rotatable within a range of 0 degrees to 90 degrees, and the other end rotates and rises upward to abut against and press the lower front side of the held object.

Next, the lifting means for the receiving table 130 will be described. As shown in FIG. 4(a), this lifting means rotates the receiving table 130 approximately 45 degrees toward the front side with respect to the recess 114, and tilts it diagonally upward.

At this time, the inclined surface 132a of the insertion portion 132 of the receiving base 130 becomes parallel to the bottom surface 114g of the vertical groove portion 114a, and the central axis of the shaft portion 132b of the receiving base 130 coincides with the central position of the long hole 114c of the bearing portion 114b of the recess 114, allowing the shaft portion 132b of the receiving base 130 to be freely raised and lowered in the vertical direction relative to the long hole 114c of the bearing portion 114b.

As shown in FIG. 4(b), when the shaft portion 132b of the receiving base 130 is positioned in the engagement hole 114d of the bearing portion 114b, the receiving base 130, which is tilted diagonally upward by approximately 45 degrees as described above, is rotated further toward the front side, so that the tip of the insertion portion 132 comes into contact with the vertical groove portion 114a, and the shaft portion 132b of the receiving base 130 is pushed toward the front side and enters the engagement hole 114d, thereby being fixed in place.

At this time, the receiving base 130 is engaged and fixed in the engagement hole 114d, and at the same time, the back side of the mounting portion 131 shown in FIG. 3 is inserted into the horizontal grooves 114f, 114f of the recess 114, preventing the receiving base 130 from rotating more than 90 degrees and determining the elevation position of the receiving base 130. Although not shown, this engagement hole 114d may be provided in multiple places other than the upper and lower ends of the long hole 114c, allowing the vertical position to be adjusted in more stages.

(Regarding leg 20)
As shown in FIG. 5, the leg 20 has a leg body 210 that is recessed and accommodated in the cutout portion 125 of the back member 120 and supports the stand body 10 at an angle, and a base 220 that receives the tip portion 211 of the leg body 210 and adjusts the angle of inclination of the stand body 10.

The leg body 210 has tip portions 211, 211 that engage with the uneven portion 221 of the base 220, and an axis portion 212 that is supported on the central side edge of the cutout portion 125 of the back member 120.

The base 220 is supported by the lower side edge of the notch 125 of the back member 120, and has a concave-convex portion 221 that engages the tip ends 211, 211 of the leg body 210. The concave-convex portion 221 has two protruding sawtooth straight lines, allowing the tip ends 211, 211 of the leg body 210 to be engaged at any point.

The base 220 also has a simple leg 230 that supports the stand body 10 at an angle without rotating and unfolding the base 220 itself. As shown in FIG. 7, this simple leg 230 is a thin, substantially rectangular plate that is received in a second cutout 222 that is formed by cutting the rear side of the base 220 from below, and is pivotally supported on the upper side of the second cutout 222 so that it can be opened to a predetermined angle.

The stand body 10, which is composed of the top surface members 110, 110 and back surface member 120 described above, and the legs 20, which are composed of the leg body 210, base 220 and simple legs 230, are each injection molded mainly from synthetic resin material such as plastic, and then assembled together.

(How to use)
Next, a method of using the stand body 10 described above for supporting an object to be supported will be described.

Place your fingertips on the finger hooks 113 of the top surface members 110, 110 and slide them left and right. At this time, the protrusions 112 of the top surface member 110 are guided by the guides 124 of the back surface member 120, and the top surface member 110 is deployed stably and without rattling.

The leg 20 is placed on a mounting surface such as a desk or table by rotating the base 220 from the rear member 120 side, unfolding the leg body 210 and the base 220. The tilt angle of the stand body 10 can be freely adjusted by rotating the tip 211 of the leg body 210 and engaging one of the recesses of the uneven portion 221 of the base 220 so that the stand body 10 is tilted at a predetermined tilt angle.

More specifically, the legs 20 can support the stand body 10 in a nearly vertical position (maximum 68 degrees in this embodiment) by engaging the tips 211, 211 of the leg body 210 with one of the recesses on the stand body 10 side of the uneven portion 221, and can also support the stand body 10 in a nearly horizontal position by engaging the rear of the uneven portion 221.

When the support base 130 holds the object to be held by leaning it against the upper position of the stand body 10, the placement portion 131 of the support base 130 is moved to the engagement hole 114d at the upper end of the long hole 114c while tilted diagonally upward, and then rotated so that it is perpendicular to the recess 114, and the shaft portion 132b is engaged with the engagement hole 114d of the recess 114 to fix the raised or lowered position of the support base 130.

When the support base 130 holds the object to be held by leaning it against the lower position of the stand body 10, the support base 130's mounting portion 131 is moved to the engagement hole 114d at the lower end of the long hole 114c while tilted diagonally upward, and then rotated so that it is perpendicular to the recess 114, and the shaft portion 132b is engaged with the engagement hole 114d of the recess 114 to fix the raised or lowered position of the support base 130.

As shown in Figures 6 and 7, the stand described above does not slide the top members 110, 110 of the stand body 10 in the left-right direction, but supports the stand body 10 at an angle with the simple legs 230, allowing a smartphone, which is smaller than a book or tablet, to be leaned up and held, and in places where there is not enough space to install the base 220, the simple legs 230 can be rotated and deployed from the base 220 to be used as a simple support leg. In this case, the stand can lean up and hold the smartphone with the charging cable connected, using the gap between the two receiving bases 130 of the stand body 10.

The above-mentioned stand can therefore be deformed by sliding the top members 110, 110 of the stand body 10 left and right relative to the back member 120, allowing different sized objects to be held upright, such as books, tablets, and smartphones, and the height can be adjusted to a comfortable viewing position for the user by using the lifting means of the support base 130 of the stand body 10.

As shown in FIG. 8, when not in use, the stand described above can be transformed into a small, flat shape by recessing the receiving base 130 into the recess 114 of the top surface members 110, 110 and recessing the legs 20 into the notches 125 of the back surface member 120, making it easy to carry by hand or by storing in a bag.

The above embodiment illustrates a preferred embodiment of the present invention, but the present invention is not limited to the above embodiment, and improvements and modifications are possible within the scope of the claims. For example, the fixing device 121 of the back member 120 can fix the top members 110, 110 so that they can slide freely in the left-right direction relative to the opening 122 of the back member 120, and a pin or the like can be used instead of a fixing screw to fix the top members 110, 110 via the opening 122.
