2. Description of the Related Art As described above, a frame body having an L-shaped cross section has a large-diameter step on the back side as a fitting step for fitting a glass plate, a book, or a back plate. In order to lock the back plate to such a frame, a large number of rotary pressers pivotally attached to the back of the frame are used. In this locking structure using a rotary presser, a number of rotary pressers are rotated after the back plate is fitted to the fitting step of the frame, and the back surfaces of the back plate and the frame are flush. Perform locking.

[0003]

However, in the above-mentioned back plate locking structure, a large number of rotary pressers must be sequentially rotated to operate, and the mounting and dismounting of the back plate is troublesome. It is said that the locking state is unstable due to pod thickness, and that the size of the fitting step of the frame and the size of the back plate must not greatly differ at the time of locking, and high precision is essential for design. There was a problem.

[0004] As an attempt to solve such a number of problems, there is a frame back plate stopper as disclosed in Japanese Utility Model Publication No. 3-35180. This back plate stopper is used by pressing the back plate against the front surface side by pressing the back plate against the front side, in the space between the rear wall formed on the back surface of the frame and the peripheral edge of the back plate. is there. For this reason, the structure of the above-mentioned rear wall is indispensable and cannot be used for a wooden frame, and only an aluminum frame is used.

In view of the above, the present invention solves the above-mentioned problems such as the inconvenience of handling of the back plate locking structure using the rotary presser, and also a wooden frame having an L-shaped cross section. It is an object of the present invention to provide a frame back plate locking structure that can be used for a vehicle.

[0007]

According to the above construction, in order to lock the back plate, for example, the back plate is inclined, and firstly, one side on which the urging member is mounted is fitted to the frame first. Fit into the step,
Then, the opposite side is also fitted into the fitting step. Then, by the biasing force of the biasing member, the one side of the fitting step portion which faces the one side of the one side Toko of the back plate is biased in the detaching direction, the back plate is fitted to the frame member Strongly locked in the combined state.

As a result of the above, according to the present invention, it has been necessary to operate the member for other locking after fitting the back plate to the fitting step portion of the frame body in the past, Locking of the back plate can be performed by the same operation as fitting the back plate to the fitting step portion, so that attachment and detachment of the back plate is very simple.

Further, the locking is performed in a state where the back plate is pressed into the fitting step, and the back plate is not pressed against the glass side of the surface as in the prior art. It can also be adjusted as appropriate, and the locked state of the back plate does not become unstable due to the size and thickness of the documents, and a stable and strong locked state can be obtained.

A sliding stopper is provided at a position where the urging member abuts on the fitting step.
Is provided to reduce the deviation from the mating step of the back plate.
This reliably prevents the back plate from being stably retained.

[0010] Further, since there is no need to provide a rear wall on the back surface of the frame, it can be used not only for aluminum frames but also for wooden frames, so that the range of use can be expanded and the practical value is high. Also have.

[0011]

An embodiment of the present invention will be described in detail below with reference to the drawings. First Embodiment FIG. 1 shows a small picture frame 1 suitable for displaying a book such as a photograph.
FIG. 1 is an exploded perspective view showing a frame 1. As shown in FIG. 1, a frame 1 has a rectangular frame 2, a glass plate 4 fitted to a fitting step 3 formed on the back side of the frame 2, and Calligraphy 5
It is composed of a back plate 6 which is fitted to the fitting step portion 3 and then locked.

The above-mentioned frame 2 is formed in an L-shaped cross section, and the opening on the front side is a posting window 2a, and the opening on the back side, which is larger in diameter than the posting window 2a, is the aforementioned fitting. Step 3 is provided. The fitting step 3 is set deeper than the combined thickness of the glass plate 4 and the back plate 6 described above.
The above-mentioned glass plate 4 is formed to have a size corresponding to the above-mentioned fitting step portion 3.
The same is true for

The above-mentioned back plate 6 is set to have a slightly shorter length in the vertical direction than the above-mentioned glass plate 4 or the above-described book 5, and a biasing member 7 is attached to the center of the upper side 6 a. A support leg 8 is mounted on the back surface.

The above-mentioned urging member 7 is appropriately formed of metal, and as shown in an enlarged perspective view of FIG. 2, urging pieces 7b, 7b are continuously provided on both sides of a mounting portion 7a having a vertical U-shaped cross section. Shape. The mounting portion 7a forms a space 7c corresponding to the thickness of the back plate 6 therein, and forms a concave portion 7d for forming a bulging portion on the inside by pressing the opposing surfaces. The recess 7 d (the inner bulging portion) is cut into the back plate 6 for mounting. The above-described biasing pieces 7b, 7b
The tilt angle and length of the back plate 6 are appropriately set so as to have a desired urging force corresponding to the vertical length of the back plate 6, and the free ends 7e, 7e are slightly bent downward. I have. On the base end side of the free ends 7e, 7e, projections 7f, 7f for preventing slippage are provided on the front side.

Next, the operation and effect will be described. In order to display the papers 5, the glass plate 4 and the papers 5 are fitted to the fitting step 3 of the frame 2 shown in FIG. 1, and then the upper side 6 a of the back plate 6 is made to correspond thereto. After adjusting the position of the biasing member 7 (the position of the upper side 3a of the fitting step portion 3 in the lateral direction and the depth direction) after coming into contact with the upper side 3a of the fitting step portion 3, The back plate 6 is pushed up against the urging force, and the lower side 6b of the back plate 6 is fitted to the lower side 3b of the fitting step 3. Then, the upper side 6a of the back plate 6 is separated from the upper side 3a of the fitting step 3 by the urging force of the urging member 7, and conversely, the lower side 6b of the back plate 6 is Is pressed into contact with the lower side 3b, and the locked state of the back plate 6 to the frame 2 is obtained (FIG. 3).

Further, in order to release the engagement of the back plate 6, for example, the lower part of the glass plate 4 can be fitted to the lower side 6b of the back plate 6 from the posting window 2a on the front surface of the frame body 2 with the lower part of the glass plate 4 on the back side. Lower side 3b of part 3
If it is pushed with a strong force equal to or more than the frictional resistance of the backing plate 6, the lower side 6b of the back plate 6 is disengaged, and
The backing plate 6 is pushed out of the fitting step 3 of the frame 2 by the urging force of (1). Alternatively, when the back plate 6 is pushed up to the upper side 3a side of the fitting step portion 3 against the urging of the urging member 7 using the support legs 8, the lower side 6b of the back plate 6 comes off and The plate 6 can be removed.

As described above, the attachment and detachment of the back plate 6 is usually performed by the back plate 6.
The work can be performed simply because the work can be performed by simply fitting the work. Moreover, it can be firmly locked by a desired urging force.

Further, since the urging member 7 is mounted by digging into the concave portion 7d formed in the mounting portion 7a, the urging member 7 can rotate slightly around the concave portion 7d. Even when the upper side 6a of the back plate 6 and the upper side 3a of the fitting step 3 are not parallel, a uniform biasing force can be applied to the left and right, and a well-balanced and stable locking state can be obtained.

Further, since the locking of the back plate 6 is not performed by strongly pressing the books 5, the back plate 6 can be stably stuck even when the posted books 5 have irregularities, for example. Can be locked.

Further, for example, even when the lateral dimension of the back plate 6 is shorter than a predetermined value, the back plate 6 is locked by the upper side 6a and the lower side 6b. In the locking operation, the back plate 6 may be shifted laterally and the prints may be shifted, but this can be prevented. For this reason, there is also an advantage that strict dimensions are not required and manufacture is easy. This is true even when the vertical dimension of the back plate 6 is shorter than a predetermined value. By preparing a plurality of urging members 7 having different urging forces, it is possible to avoid strictness in the dimensions.

In the above description, only one urging member 7 is used when applied to a small frame 1. However, when the frame is large, for example, two urging members 7 are arranged on the left and right. Good. Further, the urging member 7 may be provided on either the left or right side of the back plate 6. What is necessary is just to select suitably according to the direction in which the picture frame 1 is used, and the book 5 to be posted. (Second Embodiment) FIG. 4 shows a large picture frame 11, and two frames are provided on the upper side 6 a of the back plate 6.
In addition to mounting the urging members 7, 7, the lower sides 6b, 6b
, Two spring members 12, 12 are mounted.

The elements constituting the frame 11 (the frame 2,
The configurations of the glass plate, the papers, the back plate 6) and the urging members 7, 7 are the same as those in the first embodiment.
The same reference numerals are given and the description is omitted. In addition, back plate 6
Of the spring member 1 in addition to the urging members 7, 7
By mounting 2, 12, both members 7, 7, 1
It is set appropriately in consideration of the urging forces 2 and 12.

As shown in the enlarged perspective view of FIG. 5, the above-mentioned spring members 12, 12 are provided at one lower end on one side of the mounting portion 12a having a U-shaped vertical cross-section through the curved portion 12b in the other direction. And a spring piece 12c extending from the front end is continuously provided. Mounting part 12
a includes a mounting portion 7a of the urging member 7 described in the first embodiment.
Similarly to the above, concave portions 12d, 12d (inwardly bulging portions) are formed on the opposing surfaces so that mounting to the back plate 6 is performed. The attachment is performed such that the curved portion 12b corresponds to the front side of the back plate 6.

In order to lock the back plate 6 on which the spring members 12, 12 are attached to the fitting step 3 of the frame 2,
What is necessary is just to carry out similarly to the case of the first embodiment. That is, at the time of locking, when the lower side 6b of the back plate 6 is fitted, the curved portion 12b of the spring members 12, 12 abuts on the lower side 3b of the fitting step 3 to facilitate the above-described fitting. Further, it is locked by an urging force cooperating with the urging members 7, 7 mounted on the upper side 6a.

Therefore, in addition to the effects described in the first embodiment, the operation for locking is further facilitated, and the locking is strengthened. Then, by adjusting the urging force of the urging members 7, 7 and also adjusting the urging force of the spring members 12, 12,
Dimensional errors in manufacturing the back plate 6 and the frame 2 can be absorbed, and the manufacturing becomes easy.
