Description

[Detailed description of the invention] [Industrial application field] This invention relates to a desk with a footrest, which is often used as a study desk.

[Problems to be solved by conventional techniques and inventions] Desks have heretofore been devised in which a footrest plate is provided in the footrest space of the desk. This footrest automatically moves backwards when the chair is pushed into the footrest space of the desk.

Regarding such a desk with a footrest,
No. 23834 discloses a desk with a footrest as shown below. That is, this desk with a footrest is provided with a pair of first and second pins protruding from both sides of the rear of the footrest, and a pair of first and second pins are provided on opposite sides of the footrest space of the desk. A cam member is attached to support the footrest. Further, the cam member includes a first pin and a second pin.
A cam surface is provided to guide the pin backwards,
By applying an external force to the rear of the desk, the front part of the footrest moves rearward, causing the footrest to stand up.

However, in the case of the above-described desk, the footrest is configured to stand up centered on the second pin located behind the first pin. Therefore, when the footrest stands up, the entire weight of the footrest is applied to the second pin, and this second
There was a danger that the pins would no longer be able to withstand the weight of the footrest and would break at the base.

In addition, when using a desk, in order to return the footrest, which is in an upright state due to the chair being stored, to a horizontal state again, apply force from the rear of the desk to the front with your hands or feet. However, there was a problem with its operability. Further, in the above-mentioned desk, it is also conceivable to use a leaf spring, for example, to bias the footrest in the upright state in the direction of transitioning to the horizontal state. However, if this is done, there is a problem that the structure of the footrest becomes complicated.

[Means for solving the problem] Therefore, in order to solve the above problem, the following measures were taken. That is, claim 1 of the present invention
In this system, a pair of first and second pins projecting outward are provided on both left and right sides of the rear of the footrest, and the footrest is supported on both sides facing the foot space of the desk. A footrest is provided with opposing supporting members, and the footrest can assume both a horizontal position on which a user places his or her feet, and an upright position at the rear when not in use. In the desk with a desk, the support member includes:
a first inclined surface that contacts the lower side surface of the first pin of the footrest in a horizontal state and rises toward the rear;
A second sloped surface that contacts the lower side surface of the second pin and extends rearward to form a mountain shape, and further includes a rearward high position of the first sloped surface where the first pin is located when the footrest is in an upright state. , the distance between the second inclined surface and the rear low position is set larger than the distance between the first pin and the second pin, and by applying a rearward external force to the footrest, the footrest causes a rising behavior. The second pin of the footrest in the upright state is positioned upward from the rear position of the second inclined surface, and when the external force to the rear is released, the footrest is caused by its own weight. It is designed to automatically return to the horizontal state.

Further, in claim 2 of the present invention, the second
The present invention differs from claim 1 in that the inclined surface is provided below the first inclined surface and has a shape that extends only downward. That is, a pair of front and rear first and second pins are provided on both left and right sides of the rear part of the footrest, respectively, and project outward, and the footrest is supported on both sides facing the foot space of the desk. Support members facing each other are arranged,
In a desk with a footrest, the footrest can assume both a horizontal position on which the user rests his feet, and an upright position at the rear when not in use,
The support member is provided with a first inclined surface that comes into contact with the lower side surface of the first pin of the footrest in a horizontal state and rises toward the rear, and the lower side surface of the second pin below the first inclined surface. and a second inclined surface that descends toward the rear in contact with the footrest, and further includes a rear high position of the first inclined surface where the first pin is located when the footrest plate is upright, and a rear low position of the second inclined surface. The distance from the first pin to the second pin is larger than the distance between the first pin and the second pin, so that by applying a backward external force to the footrest, the footrest rises and is in an upright state. The second pin of the footrest is positioned above the rear position of the second inclined surface, so that when the rearward external force is released, the footrest automatically returns to a horizontal state due to its own weight. This is what was done.

[Function] In the desk with a footrest according to claim 1 of the present invention,
When attempting to store a chair in the footrest space of the desk, the chair comes into contact with the front side of the horizontal footrest. If you push the chair further behind the desk, a backward force will be applied to the footrest. Along with this, the first pin of the footrest slides on the first slope, and the second pin slides on the second slope, moving upward toward the rear of the desk. This causes the footrest to move to the rear of the desk while remaining horizontal. Further, the second inclined surface has a chevron shape, and the footrest plate moves in a horizontal state until the second pin reaches the top of the second inclined surface. Therefore, as long as the footrest receives the weight of the user's feet, the footrest will not move even if the user tries to push the footrest toward the rear of the desk.

When a further rearward force is applied to the footrest, the first pin continues to rise, the second pin passes over the top, and then descends rearward. As a result, the footrest exhibits a rising behavior.

When the footrest is pushed further into the back by the chair, the first pin further rises and reaches a high rear position where the footrest is upright.

As described above, the distance between the high rear position of the first slope and the low rear position of the second slope is greater than the distance between the first pin and the second pin. As a result, when the first pin reaches the rear high position, the second pin cannot remain in the rear low position, but reversely moves upward on the surface that has been descending until then, and is positioned slightly above the rear low position. I come to do it. This state can be rephrased as a state in which the chair presses the footrest, which is in a floating and upright state, backward while maintaining the floating state. As a result, when the chair is pulled out, the pressure on the footrest is released, the first pin at the rear high position is lowered by the weight of the footrest, and the second pin is moved to the top of the second slope. The footrest returns to its original position via the section, and the footrest returns to its horizontal state.

As described above, when the footrest stands up to an upright state and returns to a horizontal state, the first pin and the second pin are constantly moving on each inclined surface. This prevents either pin from bearing the full weight of the footrest, so there is no risk of the pin breaking.

In addition, returning the footrest from the upright position to the horizontal position can be easily done by simply pulling out the chair that has been stored.

Further, in the desk with a footrest according to claim 2,
the second inclined surface is provided below the first inclined surface,
The difference from claim 1 is that the shape extends only downward. As a result, since the mountain-shaped rising portion on the second slope is eliminated, horizontal movement of the footrest is omitted, and the footrest quickly stands up upon contact with the chair.

As mentioned above, the first pin and the second pin are provided at the rear of the footrest, but the rear of the footrest here refers to the area from the center of the footrest to the rear end. say something

[Example] An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a perspective view of a study desk 10 and a chair 12. Code 14 is a footrest, code 16
is a support member made of synthetic resin. The footrest plate 14 is supported by this support member 16. This support member 16 is attached to the left and right side plates facing the foot space 11 so as to face each other. Screws are used for this attachment, and it can be attached and detached freely. Although the study desk 12 in this embodiment is shown as a desk with one sleeve, the present invention is not limited to this, and may be a desk with both sleeves.

Both end portions of the footrest plate 14 are formed to have an arcuate cross section. The length of the footrest plate 14 in the lateral direction is approximately the same as the width of the footrest space 11. Also,
Pin holding members 18 are provided on both left and right sides of the rear portion of the footrest plate 14. This pin holding member 18 has a step shape in which the front part is thicker than the rear part, and the width between the left and right pin holding members 18 at the rear part is shorter than that at the front part by the amount of the step difference. It's summery. And pin holding member 1
A first pin 20 is attached to the rear end of the front part of the 8, and a second pin 2 of the same length as the first pin 20 is attached to the rear end of the rear part.
2 are provided in an outwardly projecting shape. Therefore, the distance between the left and right second pins 22 is smaller than that of the left and right second pins 22.
It is shorter than that of pin 20. This facilitates attachment of the footrest plate 14 to the support member 16.

Further, as shown in FIG. 2, the support member 16 is provided with a holding portion 24 on the front portion thereof that holds the footrest plate 14 in a horizontal state. The front end of this holding portion 24 is formed to have an arcuate cross section corresponding to the shape of the front end of the footrest plate 14. Although it is not always necessary to do this, if the holding portion 24 is formed as described above, the movement of the footrest plate 14 in the horizontal state in the direct upward direction is restricted. Thereby, even if the user kicks up the footrest plate 14 from below, the footrest plate 14 will not fly up. Further, the rear part of the support member 16 is wide, and this wide part has a first inclined groove 26 having the first inclined surface 25 as a side wall, and a second inclined groove arranged below the first inclined groove 26. Face 27
A second inclined groove 28 having a sidewall of . The first pin 20 and the second pin 22 slide in the first inclined groove 26 and the second inclined groove 28, respectively. Therefore, although the depths of the inclined grooves 26 and 28 are the same, the second inclined groove 28 is deeper than the first inclined groove 26 in order to receive the first pin 20 and the second pin 22 having different left and right intervals. are arranged inward by the amount of the step.

The first inclined groove 26 extends rearward upward from the lower end of the support member 16 at an angle of approximately 45 degrees. The upper part of the first inclined surface 25, which is a high rear position of the first pin 20, is oriented further upward, and when the first pin 20 is located at this part, the footrest plate 14 is in an upright state. will be shown.

Further, the second inclined groove 28 extends upwardly rearward from the lower end of the support member 16 at an angle of about 45 degrees. The second inclined groove 28 changes its direction downward at this central portion, and extends downwardly toward the rear at an angle of about 45 degrees. Therefore, the side wall of the second inclined groove 28 has a side chevron shape, and the top portion is a gentle curve. Further, the interval between the rear low position of the second inclined groove 28 and the rear high position of the first inclined groove 26 is set larger than the interval between the first pin 20 and the second pin 22. Reference numerals 30 and 32 are screw holes. A threaded rod (not shown) is inserted into this threaded hole 30,
32 and screwed into the female screws provided on the left and right side plates facing the foot space 11. In this way, the support member 16 is attached to the both side plates. In addition,
By providing the female screw at any position in the vertical direction so that the support member 16 can be installed at any height, the height of the footrest 14 can be changed freely, which will improve the growth of the child. It can accommodate changes in physique due to Reference numeral 34 indicates the holding portion 24
This felt is provided at the front end of the footrest 34, and when the foot is placed on the footrest plate 14, this felt 34 functions as a cushion. Reference numeral 36 is the support member 16
This is a stopper located at the rear end of the

Next, the rising behavior of the footrest plate 14 in the footrest space 11 will be explained.

When attempting to store the chair 12 in the foot space 11 of the study desk 10, the chair 12 comes into contact with the front side of the footrest 14 which is in a horizontal state (see FIG. 3).
When the chair 12 is further pushed to the rear of the study desk 10, a rearward force is applied to the footrest plate 14. Along with this, the first pin 20 of the footrest 14 slides inside the first inclined groove 26 and the second pin 22 slides inside the second inclined groove 28, while moving upward to the rear of the study table 10. do. As a result, the footrest 14 moves to the rear of the study desk 10 while remaining horizontal (see FIG. 4). The second inclined groove 28 from the lower end to the top is
The footrest 14 extends parallel to the first inclined groove 26, and moves in a horizontal state until the second pin 22 reaches the top of the second inclined groove 28.

When a further rearward force is applied to the footrest plate 14, the first pin 20 continues to rise, and the second pin 22 crosses the top and then descends rearward. As a result, footrest plate 1
4 shows rising behavior (see Figure 5).

When the footrest plate 14 is pushed further inward by the chair 12, the first pin 20 further rises.
Further, the second pin 22 reaches a lower rear position of the second inclined groove 28 (see FIG. 6). Although the footrest plate 14 is not upright in this state, when a rearward force is further applied to the footrest plate 14, the first pin 20
reaches the rear high position of the first inclined groove 26, and the footrest plate 14 stands upright (see FIG. 7).

As described above, the distance between the rear high position of the first inclined groove 26 and the rear lower position of the second inclined groove 27 is
The distance between the pin 20 and the second pin 22 is larger than that between the pin 20 and the second pin 22 . As a result, when the first pin 20 reaches the rear high position, the second pin 22 cannot remain at the rear low position, but reversely moves upward in the groove in which it has descended until then, moving slightly upward from the rear low position. will be located in In this upright state, the footrest plate 14 is in a floating state while being pressed backward by the chair.

In this way, the footrest plate 14 can be placed in an upright position, and the chair 12 can be stored far into the footrest space 11 of the study desk 10.

If you pull out the chair 12 when using the study desk 10,
The rearward pressure on the footrest plate 14 is released. Therefore, the first pin 2 of the footrest plate 14
0 and the second pin 22 are lowered by the weight of the footrest plate 14, and the second pin 22 is inserted into the second inclined groove 28.
(See Figure 8). after that,
As the first pin 20 continues to descend, the second pin 22 returns to the lower end of the support member 16 via the top of the central portion of the second inclined groove 28 (see FIGS. 9 and 9). (See Figure 10). This results in
The footrest 14 will automatically return to its horizontal state.

As described above, the first pin 20 and the second pin 22 are constantly moving in the respective inclined grooves 26 and 28 when the footrest plate 14 stands up to an upright position and returns to a horizontal position. This prevents either the pins 20 or 22 from receiving the weight of the footrest plate 14, unlike in the prior art, so there is no risk of the pins 20, 22 breaking.

In addition, in order to return the footrest 14 that is in the upright state to the horizontal state, it is sufficient to simply pull out the chair 12 that has been stored as described above. No operation required. Further, there is no need to install a leaf spring in the footrest plate 14 or the footrest space 11 of the study table 10 to bias the footrest plate 14 toward the front side.

In this embodiment, as illustrated, the shape of the second inclined surface 27 is made into a chevron shape, but the raised part of the chevron shape may be omitted and the second inclined surface 27 may simply extend downward.
In this case, the raising of the footrest plate 14 in the horizontal state is omitted, and when the chair 12 comes into contact with the footrest plate 14, it immediately stands up.

All other embodiments that fall within the scope of the claims for utility model registration are within the scope of this invention.

[Effect of the invention] According to the desk with a footrest according to claims 1 and 2 of the present invention, while the footrest stands up to an upright state or returns to a horizontal state, The pair of pins will always move on the inclined surface. Therefore, the weight of the rotating footrest will not be applied to either pin. This prevents the pin from being able to withstand the weight of the footrest and breaking at its base.

Further, the upright footrest automatically returns to a horizontal state due to its own weight. Therefore, when returning the footrest to a horizontal state, there is no need to operate the footrest with the hands or feet while maintaining a cramped position. Further, in order to achieve the above object, it is not necessary to provide a means for biasing the footrest plate in the forward direction, such as a leaf spring.
