Abstract

The utility model relates to a folding bookend which is composed of a bottom board, a vertical board and a support rod. Both ends of the support rod are respectively hinged with the bottom board and the vertical board. The back half part of the bottom board is provided with a front positioning groove and a back positioning groove. The lower end of the vertical board is provided with a positioning-shaft button which is fit with the front and the back positioning grooves. The utility model can be folded and after the folding bookend is folded, the periphery of the folding bookend is smooth. The folding bookend is convenient for carrying and storing. When the folding bookend is used, the folding bookend can be supported stably and a shelf is not easy to collapse.

Description

Collapsible bookend

The utility model relates to a kind of bookshelf, especially a kind of folding bookend.

Traditional bookend (Bookend) generally is to make L type or inverted T shape with hard material, places the both sides of book heap, and is upright wherein the books folder.But the riser of this bookend is generally all fixedlyed connected with base plate, therefore can not fold, and inconvenience is carried and deposited.For overcoming above-mentioned defective, people increase a tilt prop between riser and base plate, the lower end of this tilt prop (or upper end) becomes hinge property to be connected with base plate (or riser), upper end (or lower end) then becomes dropout type to be connected with riser (or base plate), riser is connected for hinge property with base plate simultaneously, like this as will carry or deposit the time, as long as an end of the dropout type of tilt prop connection is thrown off mutually with riser (or base plate), at this moment riser, base plate and tilt prop just can fold.But still there is following weak point in this collapsible bookend: the one, because of riser and base plate be a kind of rotatable but can not moving type be connected (connection of hinge property), and the relation of the position between them is: the middle part of base plate is stood in the lower end of riser, when folding like this, the upper end of riser must protrude in the front end of base plate, both can not be concordant, and are folding not ideal enough.The 2nd, because the upper end (or lower end) of tilt prop is that a kind of dropout type is connected with riser (or base plate), this connection is easy to be subjected to external force to influence and threads off, and causes often to occur the phenomenon of falling the frame in the use.

The purpose of this utility model is to provide a kind of bookend that is difficult for falling frame in even more ideal and the use that folds, to overcome the weak point of existing bookend.

The utility model is achieved in that this collapsible bookend comprises base plate, riser and support bar, and the support bar two ends become hinge property to be connected with base plate and riser respectively, promptly all can rotate around tie point; Base plate latter half of has forward and backward locating slot, and wherein the prelocalization groove is near the base plate middle part, the tie point of close base plate of back locating slot and support bar; The riser lower end has the locating shaft knob, and the riser lower end can move forward and backward the location as required on base plate like this, and when the locating shaft knob was positioned in the prelocalization groove, riser was perpendicular to base plate, and the support bar diagonal brace is between riser and base plate; When the locating shaft knob is positioned in the locating slot of back, riser, base plate, support bar three overlaid.

The advantage of the utility model structure is not only can fold, and smooth around the folding back, and supporting ﹠ stablizing is difficult for falling frame during use.Firmly overall, light weight, easy to use.

Below in conjunction with accompanying drawing, the utility model is done further concrete the elaboration.

With reference to Fig. 1, this bookend is made up of base plate 1, riser 2 and support bar 3, and there is the window 4 of revealing the exact details the front portion of base plate 1, and there is window 6 at the bottom of movable window 5 of a rectangular riser and the support bar at the rear portion of base plate 1, in the centre of riser 2, a ccontaining window 7 of support bar that adapts with support bar is arranged.The first half of base plate (slightly more than half) is below books, bear the gravity of books, when books to riser 2 directions incline by the time, riser 2 is subjected to the level effect of power backward, the support force of 3 pairs of risers 2 of support bar this moment provides therewith the reaction force of antagonism mutually, so just books folder in a row can be stood between two bookends.

With reference to Fig. 2,3,4, two parts before and after base plate 1 is divided into, anterior length direction slightly is longer than the rear portion, and width is slightly narrow than the rear portion.There is the window 4 of revealing the exact details the front portion, and the purpose that designs this window mainly is to make material to reduce cost in order to save.There is window 6 at the bottom of movable window 6 of a rectangular riser and the support bar at the rear portion, and the purpose of the movable window 5 of design riser is that the lower end of riser 2 can be moved forward and backward therein, is convenient to fold.The bottom surface of the movable window 5 of riser has prelocalization groove 8 and back locating slot 9, and respectively there is a support bar fixed shaft hole 11 both sides, bottom surface of window 6 at the bottom of support bar.All have stiffened edge 12 around the bottom surface of the periphery of the bottom surface of base plate 1 front portion and the window 4 of revealing the exact details, the bottom surface of window 6 has stiffened edge 13 as shown in the figure at the bottom of movable window 5 of riser and support bar.Periphery in the bottom surface, rear portion of base plate 1 has a kind of webbing 14 that adds, and the purpose that design adds webbing 14 is when using this bookend, makes between the rear portion of base plate 1 and the desktop to have certain space, makes prelocalization groove 8 and back locating slot 9 that enough degree of depth are arranged like this.So that the locating shaft knob 15 of riser 2 lower ends (Fig. 5, shown in Figure 6) is wherein ccontaining.

With reference to Fig. 5,6,7, riser 2 is a kind of plane bodies wide at the top and narrow at the bottom, and riser 2 lower ends have a locating shaft knob 16, and this locating shaft knob and aforesaid prelocalization groove 8 and back locating slot 9 adapt.Has a ccontaining window 7 of support bar that adapts with support bar at the middle part of riser 2, so that make support bar 3 wherein ccontaining when folding.Periphery in the bottom surface of riser 2 has stiffened edge 16 and locking edge 17, and the effect of locking edge 17 is when bookend is folding, and the front portion of base plate 1 is fastened wherein, makes whole bookend more smooth attractive in appearance.Have stiffened edge 18 around the bottom surface of the ccontaining window 7 of support bar, both sides at an upper portion thereof respectively have a support bar fixed shaft hole 19.

With reference to Fig. 8,9, support bar 3 is a kind of microscler plane bodies, has a pair of outwards outstanding support bar fixed

axis

20,21 respectively at its two ends, and they adapt with support bar fixed shaft hole 19,11 respectively, has stiffened edge 10 at the periphery of its reverse side.

From above-listed each figure as can be known, the

fixed axis

20,21 of support bar 3 respectively with riser 2 on fixed axis 19 be connected with fixed shaft hole 11 on the base plate 1.When this bookend used, the locating shaft knob 15 of riser 2 lower ends was in the prelocalization groove 8, and at this moment riser 2 is perpendicular to base plate 1, and support bar 3 diagonal braces are between riser 2 and base plate 1; When this bookend was folding, the locating shaft knob 15 of riser 2 lower ends moved backward, was placed in the locating slot 9 of back, and at this moment support bar 3 is placed in the ccontaining window 7 of support bar, and the front portion of the top of riser 2 and base plate 1 is interlocked, and bookend becomes smooth folded state.

When making base plate 1, riser 2 and support bar 3,, just stiffened edge can have been designed if they have the material of enough thickness or its making to have enough flintinesses.
