Abstract

A photo frame has a parallelogram-shaped basic frame. The photo frame can be extended or retracted to regulate based on photo size, and to be placed transversely or longitudinally by rotating a crossbar rotation knob (7) behind the photo frame based on the printing way of the photo. A photo frame group formed by a plurality of photo frames can rotate about a middle rotation axis (13). The rotation axis (13) which is hollowed out in center can be used as a vase or a pencil vase.

Description

Photo frame

Technical field

A photo frame, which uses a parallelogram as the basic frame of the photo frame, utilizes the instability of the parallelogram, so that the photo frame can be adjusted according to the size of the photo, so that the photo frame can be adapted to different sizes of photos; or according to the way the photo is printed ( In horizontal and vertical printing, the photo frame is adjusted to the corresponding horizontal or vertical position by rotating the crossbar rotation button on the back of the stereo photo frame. At the same time, the photo frame group composed of a plurality of photo frames can be rotated around the central rotation axis; the central rotation axis can also be used as a vase or a pen holder.

Background technique

Most of the current photo frames are rectangular, and the interior is hollowed out. The blanks just put the usual photos. It is mainly used for the four-sided positioning of photos, and enhances the aesthetics of photos. It is also used to protect the quality of photos. For example, photo frames with glass can prevent photos from turning yellow and so on. At present, the types of photo frames mainly include wooden photo frames, plastic photo frames, crystal photo frames, digital photo frames and other materials.

However, these types of photo frames are only material differences, but they cannot be adjusted according to the size of the photos, which causes inconvenience to the storage of the photos. Frames that cannot be adjusted in size may also be idle, resulting in wasted resources. Another feature of these types of photo frames is that the frame of the photo frame is fixed. It is not possible to adjust the arrangement of the photo frame according to the way the photo is printed (horizontal and vertical printing), which also makes the photo frame inconvenient to use.

technical problem

In order to overcome the problem that the photo frame cannot be adjusted according to the size of the photo, and only one photo can be stored, and the photo frame cannot be printed according to the photo printing mode (horizontal and vertical printing), the problem of the photo frame placement mode is adjusted, and the present invention provides a The photo frame not only can adjust the photo frame according to the size of the photo, but also can store multiple photos with the stereo photo frame group, or adjust the photo frame according to the printing mode of the photo (horizontal and vertical printing). Improve the utilization of photo frames.

The analogy of the three-dimensional parking lot, the inventor associates with the development of the photo frame to the vertical space, changing the traditional plane placement mode. After calculation, store one The 5-inch photo, the traditional photo frame with the size of 185mm *20mm*135mm, occupies an area of 148 square centimeters; while in the stereoscopic mode, the rotating stereo photo frame takes up 252 square centimeters ( 2 photos (126 cm 2 / piece) can be placed at 18cm * 14cm), and 4 photos can be placed when occupying 324 square centimeters (18cm * 18cm) ( 81 Square centimeter / sheet). It can be seen that the space saving effect of the photo frame increases with the number of displayed photos.

Each horse of the carousel has its own characteristics, leaving the artist with full space. This photo frame draws on the idea of a carousel. Since the length and opening angle of the frame frame can be adjusted, the design rights of the frame are handed over to the user.

Technical solution

( 1 The parallelogram is used as the basic frame of the photo frame, and the feature that the parallelogram is unstable is applied to the structure of the photo frame, thereby expanding the adjustment range of the area of the photo frame. The basic frame of the photo frame is a set of parallelograms fixed by diagonal rotating buttons, which makes the photo frame have certain stability, and the area of the photo frame can be adjusted by changing the angle of the diagonal angles; the other set of diagonals can be free. Activities so that the photo frame can be scaled and adjusted according to the size of the photo.

(2) The rotary button on the back of the photo frame can be rotated 360 °, so that the photo frame can be freely adjusted according to the way the photo is printed (divided horizontally and vertically).

(3 The photo frame is connected to the rotating shaft by the crossbar, and the connecting points are staggered. With the creative idea of 'stereo parking lot', the three-dimensional positioning of the photo frames is realized, and the space is avoided. At the same time, the rotating shaft uses the idea of 'carousel' to drive the photo frame. With a 360° rotation, the rotating shaft itself can also function as a vase or pen holder.

Beneficial effect

The invention has the beneficial effects that the photo frame can be telescopically adjusted according to the size of the photo, so that the photo frame can be adapted to different sizes of photos; or the photo printing mode (horizontal and vertical printing) can be used to pass the activity behind the photo frame. The bracket adjusts the photo frame to the corresponding horizontal or vertical position; it can also store multiple photos with a three-dimensional photo frame group; and arrange flowers on the rotating shaft as a room decoration. It is easy to operate, and improves the utilization of the photo frame, beautifying the living room.

BEST MODE FOR CARRYING OUT THE INVENTION

In Figure 1, ∠ BAD and ∠ BCD are connected by a rotary knob ( 1 ) and a rotary knob ( 3 ) to achieve 180 ° Rotation; and ∠ ABC and ∠ ADC can be completely fixed by the limit pin ( 2 ) and the limit pin ( 4 ).

As shown in Figure 2, when the angles of ∠ BAD and ∠ BCD are 0 °, the edges AB and AD, the edges CD and CB When overlapping, the area of the parallelogram takes a minimum of 0.

As shown in Figure 3, when ∠ BAD and ∠ BCD are rotated to 90 °, the parallel four sides are formed into a rectangle, and the area is maximized. The product of AB and BC.

As shown in Figure 4, when ∠ BAD and ∠ BCD continue to expand, when 180 ° is obtained, then BA and BC, side When DA and DC are respectively overlapped, the parallelogram area has a minimum value of 0.

From the above feasibility analysis, it is known that the parallelogram is used as the basic frame of the photo frame, and the instability of the photo frame is made such that the theoretical range of the adjustment range of the photo frame area is [0, AB*CD].

In Fig. 5, the photo frame consists of a parallelogram frame (5), a limit hole (6) on the frame, and a limit pin for fixing the frame (2). ), the crossbar rotation knob (7), the crossbar (8), and the jam (9) that fixes the crossbar rotation knob. The length of the side of the paper jam ( 9 ) is equal to the length of the side of the photo.

In Figure 6, the border (10) and border (5) that will be connected with the crossbar rotary knob Close to, then insert the jammed paper according to the size of the photo into the frame, adjust the border to a parallelogram, and align the limit hole (11) on the frame (10) according to the size of the photo (5) ) Limit hole ( 6 ).

In Figure 7, the limit pin ( 2 ) and the limit pin ( 4 ) are respectively inserted into the limit hole adjusted according to the manner of Figure 6 ( 11 ) and the limit hole (12). Since the limit pin (2) and the limit pin (4) have a pair of diagonally fixed functions, when the pair of diagonals are completely fixed, the other pair of diagonally rotating buttons (1) and the rotary knob (3) ) is also passively fixed. Thus, the frame structure of the parallelogram is fixed. This adjustment allows a photo frame to hold photos of different sizes.

In Figure 8, the crossbar knob that is attached to the cardboard (9) (7) ) Rotate counterclockwise to achieve the purpose of placing the photo frame longitudinally.

In Fig. 9, the photo frame is connected to the rotating shaft (13) by a crossbar (8), and the rotating shaft (13) is rotated by the central axis (14). ) Rotate the frame 360 ° for the fulcrum, and rotate the axis ( 13 ) to connect multiple frames. At the same time, the rotating shaft ( 13 ) is hollowed out and can be used as a vase or a pen holder.
