Description

LOCKING CLAMP SYSTEM FOR FOLDABLE DOLLHOUSE AND

FOLDABLE DOLLHOUSE

Field of the invention

The invention relates to the field of toys, more specifically to the field of foldable dollhouses and their locking systems. The invention provides a locking clamp system for a foldable doUhouse, and a foldable doUhouse.

Prior art

Various foldable and folding play and dollhouses are well-known in the art.

German Utility Model DE202006010621 discloses a foldable playhouse which is provided with a locking mechanism, which ensures enough stability and security and does not enable children to fold and unfold the playhouse on their own.

U.S. Patent US6527609 discloses a doUhouse, the walls of which have magnetic sheets for installation purposes.

German Patent Application DE102011084959 discloses a foldable doUhouse which consists of modular walls which are provided with magnets for joining with each other.

German Utility Model DE202007008960 discloses a cardboard doUhouse system, the walls of which are joined with each other with magnetic rods.

The disadvantage of the available solutions is that folding up and unfolding of the doUhouse is time-consuming, too complicated for children or the construction is not stable enough.

Currently, there is no solution for a doUhouse which takes little room in a folded state and which is quickly and conveniently detachable and foldable, while being secure and stable enough for carrying doUhouse furniture and for playing in the doUhouse, so that children could manage to detach and fold it up themselves. Summary of the invention

This invention relates to a locking clamp system for a foldable dollhouse and a foldable dollhouse. The locking clamps are special interconnecting clamps for connecting the wall panels and floor panel of the floor module, for connecting the floor modules with each other, and for connecting the roof floor with the module. A floor module of the dollhouse consists of three wall panels and a floor panel that can be connected with each other by locking clamps. The locking clamps enable unfolding and folding up the wall panels and floor of the floor module of the dollhouse quickly and conveniently. In the unfolded state, the wall panels and floor panel form a strongly fixed three-dimensional space which can be connected other unfolded dollhouse floor modules of similar type, thus forming a multistorey dollhouse. The roof floor module of the dollhouse consists of two roof floor wall panels, a floor panel, and a roof panel which can be connected with each other by locking clamps. At the same time, in the folded state, the dollhouse and its modules are almost entirely two-dimensional book-like objects which do not take much space during storage. Upon unfolding, the locking clamps lock the wall and floor panels of the floor module of the dollhouse to each other and upon folding up, the locking clamps unlock the wall and floor panels of the module of the dollhouse. Similarly, upon unfolding, the locking clamps lock the wall panels, the floor panel, and the roof panel of the roof floor of the dollhouse to each other, and upon folding up, the locking clamps unlock the wall panels, the floor panel, and the roof panel of the roof floor of the dollhouse.

The invention provided in this description enables locking and fixing quickly and securely the wall and floor panels of the floor module of the dollhouse to each other, and also various modules of the dollhouse, including the module of the roof floor. Locking clamps enabling storing the modules of the dollhouse in the detached state being stacked on each other.

Example of carrying out the invention

The invention is based on a locking clamp system that consists of front locking clamp system 1 and rear locking clamp system 2 for a foldable doUhouse as depicted in Figures FIG 1, 2A-2C, 9, lOA-lOC. Front locking clamp system 1 comprises front side clamp 3 according to Figures FIG 3, 4, 5B and the front base clamp 4 according to Figures FIG 6, 7, 8B. The front side clamp and front base clamp are connectable to each other, and the front side clamp and front base clamp are in turn connectable to wall panel 5 (see Figure FIG 17), floor panel 6 of the module of the doUhouse (see Figures FIG 17, 20), and wall panels 7 of the roof floor (see Figure FIG 20). The rear locking clamp system comprises rear side clamp 8 according to Figures FIG 11, 12, 13B and the rear base clamp 9 according to Figures FIG 14, 15, 16B. The rear side clamp and rear base clamp are connectable to each other, and the rear side clamp and rear base clamp are in turn connectable to wall panel 4 (see Figure FIG 17), floor panel 5 of the module of the doUhouse (see Figures FIG 17, 20) and wall panels 7 of the roof floor (see Figure FIG 20).

Front side clamp 3 consists of vertical U-shaped section 10, the bottom side of which has a T-shaped tongue 11. This T-shaped tongue 11 has in at least one end barrier 12 to impede the sliding of the front side clamp 3. Wall panel 5 of the doUhouse and wall panel 7 of the roof floor are attached to the vertical U-shaped section 10 and the T-shaped tongue 11 is attached to groove 12 of the front base clamp 4. Rear side clamp 8 consists of a vertical U-shaped section 13, the bottom side of which has a T-shaped tongue 14. The T-shaped tongue 14 of the rear side clamp 8 is shorter than tongue 11 of the front side clamp. Wall panel 5 of the dollhouse and wall panel 7 of the roof floor are attached to the vertical U-shaped section 13 and the T-shaped tongue 14 is attached to groove 15 of the rear base clamp 9. Unlike the tongue of the front side clamp, tongue 14 of the rear side clamp 8 has no barrier.

The front base clamp 4 consists of a horizontal U-shaped section 16, the side of which has perpendicularly two mutually located grooves 12 and 17. Floor panel 6 of the dollhouse is attached to this horizontal U-shaped section 16. Of those mutually located grooves, to the upper groove 12 is attached the T-shaped tongue 11 of the front side clamp 3, and to the lower groove 16 is attached the upper edge of the wall panel 5 of the module of the dollhouse.

The rear base clamp 9 consists of a horizontal U-shaped section 18, the side of which has perpendicularly two mutually located U-shaped grooves 15 and 19. Floor panel 6 of the dollhouse is attached to this horizontal U-shaped section 18. Of those mutually located U- shaped grooves, to the upper groove 15 is attached the T-shaped tongue 14 of the rear side clamp 8, and to the lower groove 19 is attached the upper edge of the wall panel 5 of the module of the dollhouse.

Side clamps 3, 8 and base clamps 4, 9 can accordingly be fixated to wall panels 5, base panel 6, and wall panel 7 of the roof floor by fastening means that can be, for example, adhesive, rivets, whereas if rivets are used, hole 20 is located in the horizontal section 16, 18 and vertical U-shaped section 10, 13.

The horizontal U-shaped section 16, 18 of base clamp 4, 9 that has holes 12 for riveting enables installing and riveting base clamp 4, 9 to floor panel 6 of the dollhouse; floor panel 6 is placed between the horizontal U-shaped section 16, 18 of base clamp 4, 9 and is attached to base clamp 4, 9 by the rivet connected through its holes 20 and through the floor panel 6.

The t-shaped groove 12, 15 of base clamp 4, 9 is intended for locking the side clamp 3, 8 with the T-shaped tongue 11, 14. In order to facilitate the insertion of tongue 11, 14 to groove 12, 15, tongue 11, 14 has the front end with phasing 21. The lower part of base clamp 4, 9, which has the U-shaped section 16, 18, is intended to be based both on floor panel 6 or floor and on the edge of wall panel 5 of the module of the dollhouse, so that the modules of the dollhouse could be installed stably on each other, being based directly on the bottom module of the dollhouse, which minimises fluctuation and helps to keep wall panels 5 of the bottom module of the dollhouse and wall panels 7 of the roof floor straight, so that the centre of gravity of the upper module of the dollhouse would not break or bend wall panels 5 of the bottom module of the dollhouse. The set of one floor, including the set of the roof floor, includes four base clamps 4, 9, i.e. 2 front and 2 rear base clamps in the side edges of the floor panel 6; so that the module of the dollhouse that is installed on the top holds tight and the modules of the dollhouse are stable between themselves, while being easily detachable.

The purpose of side clamp 3, 8 is to lock wall panels 5 of the module of the dollhouse, so that they would not move from right to left and up and down.

There are 4 side clamps in the set, i.e. two front side clamps and two rear side clamps, which are attached to base clamps 4, 9 to lock the unfolded module of the dollhouse. Side clamp 3, 8 can be locked in base clamp 4, 9 by pressing on it (from top to bottom or by pulling by its groove 12, 15). In order to deactivate, side clamp 3, 8 is pulled out of groove 12, 15 (from bottom to top or by sliding out of groove 12, 15). The locking section of the front side clamp 3, which is pressed or pulled in base clamp 4, has in one end barrier 12 or a thicker part which impedes the front side clamp 3 from sliding out of groove 12.

Front and rear clamp system 1 provided by the invention can be quickly assembled and disassembled; clamps 3 and 4, and 8 and 9, respectively, can be fixed to each other and these can be strongly attached to cardboard used as material for the floor modules and the roof floor module. The modules of the foldable dollhouse depicted in Figures FIG 17-23 comprise a floor module that consists of four details: two sidewall panels 5, floor panel 6 and rear wall panel 5. The roof floor module as depicted in Figures FIG 20-24 A, B, C consists also of four details: two roof floor wall panels 7, roof panel 25, floor panel 6. For folding up and unfolding the module, there is an articulation 22 between the sidewall panels and rear wall panel (for the roof floor, between the roof floor wall panels and roof panel, respectively). In a preferred embodiment of the invention, for the articulation, the edge of the side wall panels is on the rear wall panel (for the roof floor, the edge of the roof floor wall panels on the roof panel, respectively) with overlay 23, which enables attaching the side wall panels by adhesive or rivets to the rear wall panel of the module of the dollhouse (for the roof floor, the wall panels of the roof floor are attached to the roof panel, respectively). The overlay of the sidewall panels 5 (for roof floor, the overlay of the roof panel, respectively) gives the load-bearing strength to the floor module or roof floor module. Overlays 23 of the side wall panels (for the roof floor, the overlays of roof floor wall panels, respectively) are riveted or glued to the rear wall panel 5 (for the roof floor, to the roof panel, respectively), doubling therefore the corner thickness of the module of the dollhouse and giving significant strength and stability to the construction of the module of the dollhouse as a whole; the resulting articulation enables folding up and unfolding the side wall panels (for the roof floor, the roof floor wall panels, respectively).

Floor panel 6 and rear wall panel 5 (for the roof floor, the roof panel 25, respectively) are in one piece and a two-part hinge 5a of the floor panel is located in between them. In the front edge of the floor panel 6, which is located facing the attached edge of the rear wall panel 5 (for the roof floor, the roof panel 25, respectively), there is an angular forehand 24. The reinforcement of angular forehand 24 helps to prevent the fluctuation of the floor panel 6 of the module of the dollhouse and provides it with significant strength and rigidity. In addition, the angular forehand 24 protects wall panels 5 of the module of the dollhouse (for the roof floor, wall panels 7 of the roof floor, respectively) in its folded state. The angular forehand 24 gives to the assembled module the consistent impression in each case of assembly - the module turns into a small box, reminding of a book.

Hinge 5a of the floor panel between floor panel 6 and rear wall panel (for the roof floor, the roof panel 25, respectively) gives to the module of the dollhouse enough flexibility to move forth, back and also down, which is necessary for connecting locking clamps 3 and 8, so that base clamps 4, 9 could be locked with side clamps 3, 8 of side wall panels 5 (for the roof floor, of the wall panels 7 of the roof floor, respectively), and therefore to fix the module in its unfolded state. In addition, the narrow space created by the two-part hinge section 5a of the floor panel enables hiding upon folding up the module the side wall panels 5 (for the roof floor, wall panels 7 of the roof floor, respectively) with side clamps 3, 8 between the rear wall panel 5 (for the roof floor, roof panel 25, respectively) and floor panel 6. This way, the folded module of the doUhouse is thin enough to be placed, for example, in a shelf (like a book).

On both edges of the two side wall panels 5 of the module of the foldable doUhouse (for the roof floor, wall panels 7 of the roof floor, respectively), there are two side clamps 3, 8, and on both opposite edges of floor panel 6, there are two base clamps 4, 9. Side clamps 3, 8 and base clamps 4, 9 can be locked with each other, forming in its unfolded state a dimensional module of the doUhouse, as depicted in Figure FIG 23.

According to a preferred embodiment of the invention, wall panels 5 (for the roof floor, wall panels 7 and roof panel 25 of the roof floor, respectively) and floor panel 6 of the foldable doUhouse are made of cardboard.

The module of the doUhouse described in this invention can be conveniently and quickly (approx. 10-30 seconds) folded up and unfolded, whereas the folded module of the doUhouse has enough space for fitting locking clamps 3, 8 and 4, 9, and has similarly to books or file cases a so-called 'backplate' for the information regarding the contents of the module of the doUhouse.

In a preferred embodiment of the invention, the module of the doUhouse comprises eight locking clamps: four base clamps 4, 9 that are attached to the edge of the floor panel 6, and four side clamps 3, 8 that are attached to wall panels 5 of the module of the doUhouse (for the roof floor, to wall panels 7 of the roof floor, respectively).

Deactivation of LOCKING CLAMPS

Both clamps, i.e. base clamp 4, 9 and side clamp 3, 8 are deactivated by a smooth stroke out of the groove (from bottom to top) or by sliding out of the groove (from back to forth):

1. Side wall panel 5 (for the roof floor, wall panel 7 of the roof floor, respectively) is opened and placed to the rear wall panel 5 (for the roof floor, to roof panel 25, respectively) - first movement.

2. Second wall panel 5 (for the roof floor, wall panel 7 of the roof floor, respectively) is opened and placed to the rear wall panel 5 (for the roof floor, to roof panel 25, respectively) - second movement. Floor panel 6 is turned against rear wall panel 5 (for the roof floor, against roof panel, respectively) and the module of the dollhouse is folded - third movement.
