Description

Extendable cradle

Field of the Invention

The present invention relates generally to the field of cribs, and more specifically refers to an extensible crib that can be adapted to the size of the baby as it grows.

State of the art

It is well known that the rapid growth of babies in their early years requires that cribs of various sizes be adapted to each stage of growth. For example, up to three cribs of different sizes may be required in the first three years of a baby's life. Obviously, this implies a great cost that it would be desirable to avoid.

Various solutions have been proposed in the art that are intended to solve said problem, providing cribs that can be configured with various sizes as the baby grows. However, most of the solutions proposed to date generally provide cribs that have a limited number of configurations, for example three, but cannot adapt to continued growth of the baby. In addition, the extensible cradles known in the state of the art are complex for the end user, making it difficult to modify the configuration of the cradle. In addition, this complexity also affects time and manufacturing costs, thereby affecting the final price of the item produced.

Therefore, there remains a need in the art for an extendable crib whose configuration can easily adapt to the size of the baby as it grows. In addition, there is a need for a cradle of this type that is simple and economical to manufacture, as well as easy to configure by the end user.

Summary of the invention

The present invention relates to an extensible cradle comprising:

-

at least two legs;

-

a cradle body formed by an upper rectangular frame and a lower rectangular frame each consisting of two crossbars and two stringers, as well as two short walls parallel to each other and two long walls parallel to each other defined between said upper and lower frames; Y

-

a bed base arranged at the base of said cradle body.

According to the present invention, said long walls of the cradle body and said bed base can move continuously between a collected position and an extended position thus varying the internal volume of said cradle body.

Therefore, thanks to the present invention, a cradle is provided that can be easily adapted to all stages of a baby's growth, continuously, as the baby grows.

Detailed description of the preferred embodiment

Figure 1 shows a complete extensible cradle according to the preferred embodiment of the present invention, in a perspective view. It can be seen that said cradle comprises a cradle body (10) formed by an upper rectangular frame and a lower rectangular frame each consisting of two crossbars (12) and two stringers (14), as well as two short walls (16) parallel between yes and two long walls (18) parallel to each other defined between said upper and lower frames.

The extensible cradle also comprises two legs (20) as well as a box spring (not visible in this figure). Legs

(20) extend vertically downwards from the central part of each short wall (16), subsequently dividing into two horizontal extensions of support on the floor thus providing the stability required for the extensible cradle.

According to the preferred embodiment shown in Figure 1, the legs (20) have, at the ends of each of said horizontal support extensions, wheels (22) which will be described hereinafter.

Referring to Figure 2, a lower frame of the cradle body described with reference to Figure 1 is shown. It will be understood by analogy that the upper frame of the cradle body (10) will be similar to the lower frame described below. In this figure it can be seen that said lower frame is actually constituted by two lower half-frames. Each of said half-frames comprises a lower cross member (12) and two lower half-bars (14A, 14B). As can be seen in this figure, the half-rods (14A) of the first half-body have an inner hollow, larger than the half-rods (14B) of the second half-body, so that said half-rods (14B) of the second half-body are coupled and slid in the interior of the half-rods (14A) of the first half-body.

As can be seen in this figure, the half-rods (14B) coupled inside the half-rods (14A) can slide telescopically with respect to the latter, between an extended position and a collected position.

According to an embodiment of the invention, said half-rods have a series of fixed positions (for example, at least three fixed positions) in which the half-rods (14B) are locked inside the half-rods (14A) for example by the use of a screw with nut or similar inserted in a hole arranged for this purpose. In this way an additional level of security is provided to the cradle by preventing unwanted displacement of the half-beams. Additionally, the last fixed position will constitute a stop that prevents the half-rods (14B) from leaving the half-rods (14A) in an undesired manner.

Although not shown in this figure, the upper frame of the extensible cradle is constituted similarly to the lower frame described above, and the cradle further comprises short (16) and long walls (18) defined between said upper and lower frames. In this way, by sliding the half-rods (14B) (both upper and lower) inside the half-rods (14A) (both upper and lower), the interior volume of the cradle body (10) defined is easily varied by the short (16) and long (18) walls thereof.

It will be apparent to the person skilled in the art that, since each of the cradle half-bodies comprises long half-walls (18A, 18B) defined between the respective upper and lower half-rods, when the cradle is in the said position, said long half-walls (18A, 18B) will be superimposed next to each other. On the other hand, in a fully extended position, said long semi-walls (18A, 18B) will be arranged one after the other without providing any or substantially no overlap between them.

In Figure 2 it is further appreciated that, according to the preferred embodiment of the present invention, the lower frame comprises additional intermediate stringers (14C, 14D) to provide greater support for the bed base. Said intermediate stringers (14C, 14D) will have a structure similar to that of the stringers (14) of the ends (that is, they are formed by semi-stringers (14C, 14D) sliding telescopically one inside the other), although they will be arranged to a vertical level below the rest of the lower frame.

It can also be seen in Figure 2 that the half-rods (14A, 14B) also have rails (24) arranged to introduce projections (not shown in these figures) present at the longitudinal ends of the slats that constitute the bed base (as will be described continued in this document). Said rails (24) act as fixing means for said slats, as well as guiding their movement between the collected position and the extended position.

Obviously, the upper frame of the cradle body (10) will differ from the lower frame just described in that it will lack intermediate stringers (14C, 14D) as well as rails (24) for the bed base.

Next, in relation to Figures 3, 4A, and 4B, the constitution of the bed base according to the preferred embodiment of the present invention will be described. Said bed base consists of slats (26). Figure 3 shows

two of said slats (26) engaged in fully extended position. It can be seen that each strip (26) is formed by an elevated zone (26A) followed by a recessed zone (26B). The raised area (26A) will serve as a support for a mattress, while the extension of the lowered area (26B) will define, as described below, the extension capacity of the bed base. The slats also have a first stop wall (28A) at the transverse end of the raised area (26A) and a second stop wall (28B) at the transverse end of the recessed area (28B). In this way, the slats are coupled to the first abutment wall (28A) of a slat in the recessed zone (28B) of another slat, so that the extension path of each slat is defined by the distance that the first can travel stop wall (28A) of a first strip between the raised area (26A) and the second stop wall (28B) of the second strip (ie, the distance of the recessed area (26B) of the second strip).

Thus, in figure 4A a crib bed base is shown in a top view according to the preferred embodiment of the invention, constituted by a succession of slats coupled to each other, in the collected position. In this position, the first stop wall (28A) of each slat is in contact with the raised area (26) of the next slat. In contrast, a view similar to that of Figure 4A is shown in Figure 4B, but in which the slats have moved to their extended position, in which the first stop wall (28A) of each blade is in contact with the second stop wall (28B) of the following slat. Although these figures show the two end positions (collected and extended) that the cradle bed base can adopt according to the preferred embodiment of the present invention, it will be evident to the person skilled in the art that the bed base can be configured in any intermediate position, passing continuously between the collected position and the extended position.

Finally, in figures 4A and 4B there are also projections (30) arranged in both longitudinal ends of the slats (26), intended to be introduced in the rails (24) as described hereinabove.

The wheels (32) of the cradle according to the preferred embodiment of the invention will now be described, in relation to Figures 5A and 5B. As can be seen, said wheels (32) are attached to the ends of the horizontal extensions of the legs (20). When it is desired that the cradle remains stable in a fixed position, the wheels (32) will be fixed to the legs (20), by any means known in the art (for example a through screw in the axis of rotation thereof) in collapsed position, so that the wheels are parallel to the ground (shown in Figure 5A). On the contrary, when it is desired to move the cradle to a new location, the wheels (32) will be turned 90 ° to move to a rolling position, perpendicular to the ground (shown in Figure 5B).

As shown in Figure 6, the structure of the cradle's legs has a vertical lifting rail

(3. 4)

 directed into the cradle body (10). This vertical lifting rail (34) is intended to couple a slide carriage (36) arranged approximately in the center of the short sides of the bed base (shown in Figure 7). In this way, the sliding carriage travel (36) along the vertical lifting rail

(3. 4)

 It allows you to continuously vary the height of the bed base between a high position and a low position.

Furthermore, as also shown in Figure 7, the extendable cradle further comprises fixing means of the bed base in a desired lifting position in the form of a clamping screw (38) disposed in the sliding carriage (36).

According to another preferred embodiment not shown in the attached figures, the cradle of the present invention also comprises means for lifting the legs. Said means for lifting the legs are constituted, for example, by a gas piston located inside the housing of the legs, forming the internal structure of the leg and in which a bed base guide is located. At the top of each leg is a piston activation button. Therefore, the pistons will be activated if both buttons are pressed at the same time.

According to another embodiment of the invention, said buttons also have a safety system consisting of a spring that contracts after a force with the hand and then this in turn activates the button.

According to other embodiments of the invention, said leg lifting means can be of any other type known in the art, for example they can be constituted by retention stops and by various lifting points arranged in height.

In addition, according to yet another preferred embodiment of the present invention, the extensible cradle can also be suitably used as a desk. Indeed, according to this embodiment, it is possible to disassemble the walls and the base that constitute the body of the extendable cradle, and fix by clamps an upper board to the upper rectangular frame so that the extendable cradle becomes a children's desk.

Although the present invention has been described with reference to a specific preferred embodiment thereof, it will be understood that variations and modifications may be applied thereto without thereby departing from the scope of protection of the appended claims. For example, the number of legs of the cradle may be varied (provided that they provide the necessary stability to it, preferably at least two legs), the constitution of the means for fixing the bed base in its desired lifting position, the realization of the wheels and their rolling and non-rolling positions, etc., without thereby departing from the scope of the present invention.
